Kigelia africana fruit: Constituents, bioactivity, and reflection on composition disparities
Ahmed Galal Osman, Zulfiqar Ali, Amar G Chittiboyina, Ikhlas A Khan
October-December 2017, 3(4):1-6
Objective: Kigelia africana, a tropical tree, which has long been used in African traditional medicine. The objective of the current study has been identifying the constituents of K. africana and verifying its utilities in traditional medicine. Materials and Methods: The methanol extract of K. africana fruits was subjected to chromatographic fractionation utilizing different techniques. The methanol extract together with the isolated compounds were tested for their bioactivities in a series of cell-based assays. Results: The current work led to isolation and characterization of nine constituents including iridoid glycosides, phenylpropanoid derivatives, and a eucommiol derivative. The hexanes extract caused inhibition of the opportunistic yeast; Cryptococcus neoformans Pinh. The chloroform extract exhibited substantial antileishmanial activity of Leishmania donovani. Verminoside (1) showed weak inhibition of the CB1, CB2, and Kappa opioid receptors. Compound 4 exhibited weak inhibition of the Kappa and Mu opioid receptors. The hexanes and the chloroform extracts of K. africana exhibited inhibitory activity against the pathogenic parasite Trypanosoma brucei. The ethyl acetate extract showed the same activity. Conclusions: This is the first report on the isolation of coniferyl 4-O-β-D-glucopyranoside (7), a eucommiol derivative (crescentin IV) (6), and 6-feruloylcatalpol (4) from the genus Kigelia. It is also the first report on the separation of ajugol (2), catalpol (3), and specioside (5) from the fruits of K. africana. Revision of the 1H and 13C-NMR spectra of 6-feruloylcatalop (4) and 6-p-hydroxycinnamoylcatalpol (5, specioside) is described. Further, the results of the in vitro assays corroborate the traditional utility of this plant in medicine.

Xiao chai hu tang for liver diseases: A literature review
Yi Wang, Li Li, Yan-Mei Cheng, Sheng-Liang Zhu
July-September 2017, 3(3):46-50
The objective of this study is to summarize the pharmacological effects and the mechanisms of action of Xiao Chai Hu Tang (XCHT, Minor Bupleurum Decoction) on liver diseases, so as to give relevant researchers a valuable insight and benefit patients with hepatopathy. PubMed was used to search for and collect scientific publications related to XCHT and liver diseases from 1986 to 2016. The available scientific results or evidence were read, classified, and analyzed. XCHT showed clinical efficacy in patients with hepatic diseases including hepatitis, hepatic fibrosis, and hepatoma. The mechanisms involved the production of cytokines, the regulation of immune function, the suppression of lipid peroxidation, etc., XCHT might work on the metabolism of some medications such as tolbutamide by the regulation of gastric emptying and intragastric pH. XCHT exhibited a very low toxicity profile, such as interstitial pneumonia due to duration of medication, patients' age, and drug combination. XCHT has been a eutherapeutic supplemental remedy for liver diseases. However, many mechanisms of action and effects of XCHT on new types of liver diseases still remain unclear, so more and more animal experiments and human clinical trials are needed to obtain enough proofs for the clinical use of XCHT in new types of hepatosis such as nonalcoholic fatty liver disease and autoimmune liver disease.

Xiao-Ping Zheng, Fang-Di Hu, Li Yang, Yu-Ling Ma, Bo-Lu Sun, Chang-Hong Wang, Zheng-Tao Wang
July-September 2017, 3(3):12-17
Background: The Qing'e formula (QEF) is a well-known traditional Chinese prescription that has been clinically employed for treatment of bone disease for hundreds of years. Objective: The present study aims to observe the effects of different compatibilities of QEF on the scopolamine-induced learning and memory impairment in the mouse, and further to explore its action mechanisms and compatibility rationality. Materials and Methods: The learning and memory alterations in the mouse were evaluated using the step-down test and Morris water maze (MWM) test; the acetylcholinesterase (AChE) activity and brain-derived neurotrophic factor (BDNF) expression in the hippocampus were measured using colorimetric method or immunohistochemistry. Results: The results showed that different compatibilities of QEF significantly prolonged latency in the step-down test, shortened escape latency in the navigation test, increased the percentage of residence time, and the percentage of swimming distance in the target quadrant in the probe trial session. In addition, our results also found that different compatibilities of QEF remarkably inhibited AChE activity and increased BDNF expression in the hippocampus of mice. What's more, the group after being treated with whole recipe (QF) showed the highest level of improvement. Conclusions: These findings not only suggest that QEF may effectively ameliorate cognitive deficits through inhibiting AChE activity and increasing BDNF expression in the hippocampus but also elucidate the rationality of QEF.

Zhi-Jie Ding, Dan-Qing Xu, Yuan-Zhi Lao, Hong-Xi Xu
July-September 2017, 3(3):38-45
Herbal medicines, including traditional Chinese medicines (TCMs), have been used in Eastern countries for treating diseases such as cancer for thousands of years. With the growing knowledge of tumorigenesis and cancer therapy, some natural compounds have been developed as clinical anticancer drugs. In addition, many compounds and TCMs have been characterized as complementary and alternative treatments, with synergetic effects on enhancing the efficacy or reducing the side effects of the therapeutics. In this review, we summarized the recent studies focusing on the combination of natural compounds or TCM decoction with chemotherapeutics. The detailed mechanisms of action of the combinations and the application of analytical methods on TCM development are also discussed.

Ikuo Saiki, Satoru Yokoyama, Yoshihiro Hayakawa
October-December 2017, 3(4):26-45
A Japanese herbal (Kampo, [INSIDE:1]) medicine, [INSIDE:2] (juzentaihoto/Shi-Quan-Da-Bu-Tang), is one of the nourishing agents, a so-called “[INSIDE:3] (Hozai/Bu-Ji),” that is used for improving disturbance and imbalances in the homeostatic condition of the body. This formulation is orally administered to patients in various weakened states, including postsurgery patients and patients with chronic illness, where it can alleviate general symptoms such as extreme fatigue, pale complexion, loss of appetite, dry or scaly skin, night sweating, and dryness of the mouth. Recently, juzentaihoto/Shi-Quan-Da-Bu-Tang has been shown to have a variety of biological activities, including activation of natural killer cells and macrophages, cytokine induction, antibody production, antitumor effects in combination with surgical excision or other drugs, and protection against the adverse effects of anticancer drugs and radiation, including immunosuppression and bone marrow toxicity. This article focuses on the antitumor and antimetastatic properties of some Kampo medicines and mainly describes the effects of juzentaihoto and its related formulations on tumor development, progression, and metastasis in vivo. We also discuss the inhibitory mechanism of action and the importance of the prescription and constituent crude drugs in determining the efficacy.

Progress of studies on traditional chinese medicine based on complex network analysis
Qian-Ru Zhang, Xiang-Jun Kong, Hai-Yu Xu, Yi-Tao Wang, Yuan-Jia Hu
July-September 2017, 3(3):28-37
Traditional Chinese medicine (TCM) is a distinct medical system that deals with the life–health–disease–environment relationship using holistic, dynamic, and dialectical thinking. However, reductionism has often restricted the conventional studies on TCM, and these studies did not investigate the central concepts of TCM theory about the multiple relationships among life, health, disease, and environment. Complex network analysis describes a wide variety of complex systems in the real world, and it has the potential to bridge the gap between TCM and modern science owing to the holism of TCM theory. This article summarizes the current research involving TCM network analysis and highlights the computational tools and analysis methods involved in this research. Finally, to inspire a new approach, the article discussed the potential problems underlying the application of TCM network analysis.

Ahmed Attia Ahmed Abdelmoaty, Yu-Ling Ma, Ruibin Bai, Xiao-Ping Zheng, Fang-Di Hu, Ying-Dong Li
October-December 2017, 3(4):7-14
Objective: The present study aims to optimize the extraction conditions of polysaccharides and flavonoids from a polyherbal preparation consisting of three kinds of Chinese medicinal herbs, Codonopsis pilosula, Crataegus pinnatifida, and Lycium barbarum, and evaluation of its immunomodulatory activity in immunosuppressed mice. Materials and Methods: An orthogonal design (L9 [3]4) was constructed to achieve the optimal extraction conditions. The immunomodulatory action of the polyherbal preparation was studied at three doses of 10, 20, and 40 mL/kg/day orally by measuring splenocyte proliferation in mice model of cyclophosphamide-induced immunosuppression. Results: The chosen parameters, including the ratio of solvent-to-raw material, duration of extraction, and extraction times, were the fundamental variables that influenced the extract yields. The highest yield of total polysaccharides content was 54.3 mg/mL when the ratio of solvent-to-raw material, duration of extraction, and number of extractions were 12:1, 1.5 h, and 3, respectively. The maximum extraction yield of the flavonoids was 3.5 mg/mL when the ratio of solvent-to-raw material was 12:1, the extraction time was 2 h, and the number of extractions was 3. The prescription screening showed that the impact of the polyherbal preparation on the splenocyte proliferation capacity was more pronounced than its disassembled components. Oral administration of the polyherbal preparation could significantly increase the concanavalin A-stimulated mouse spleen cells proliferation in a dose-dependent manner. Conclusion: These findings suggested that the polyherbal preparation possesses potential for augmenting the immune activity due to the polysaccharide and flavonoid content in these herbal medicines.

Ying Zhang, Lin-Jie Xu, Yu Zheng, Feng-Quan Xu
July-September 2017, 3(3):51-57
Objective: The objective of this study is to evaluate the effectiveness and safety of traditional Chinese herbal medicine (TCHM) in treatment of perimenopausal depression (PD) in China. Methods: To identify randomized controlled trials, an electronic search has been conducted through databases as follows: PubMed, the Cochrane Central Register of Controlled Trials, Web of Science, Chinese Biological Medicine Database, China National Knowledge Infrastructure Database, Chinese Scientific Journal Database, and WanFang Digital Periodicals Database. Methodological quality was evaluated by Cochrane Collaboration's tool which is able to assess the risk of bias in Review Manager Software. What's more, meta-analysis was performed by using Cochrane Collaboration's RevMan 5.2 software, (Nordic Cochrane Centre, Cochrane Collaboration, Copenhagen, and Denmark). Dichotomous data were analyzed by using relative risk (RR) and 95% confidence interval (CI). Continuous variables were analyzed using weighted mean differences (WMDs) and 95% CI. Subgroup analysis was performed by the type of medicine which was used in the experimental group. Results: This meta-analysis includes 11 randomized control trials with 818 patients. Compared to the control group (RR: 1.14, 95% CI: [1.03, 1.26], P = 0.009 and WMD: −2.09, 95% CI: [ −3.58, −0.18]), the experimental group had a significant higher clinical efficacy rate and relatively lower Hamilton Depression Rating Scale (HAM-D) score. For clinical efficacy rate, the results varied depending on the detail treatment measures of the experimental group. In the experimental group with TCHM, no significant difference was observed (RR: 1.14, 95% CI: [0.97, 1.33]), while in the experimental group combined with western medicine, a significant difference in the clinical efficacy rate between the experimental group and control group showed up (RR: 1.15, 95% CI: [1.01, 1.32], P = 0.04). For the HAM-D score, subgroup analyses revealed that the pure TCHM therapy was not associated with significant HAM-D score reduction compared to the control group (WMD: −2.48, 95% CI: [−6.00, 1.03], P = 0.17). However, in the experimental group where western medicine was added to, the HAM-D score decreased statistically compared to the control group (WMD: −1.88, 95% CI: [−3.58, −0.18], P = 0.03). There is no serious adverse event in both groups. Conclusions: Combination therapy of TCHM and western medicine is more effective in treating PD in terms of clinical efficacy rate. However, the results should be interpreted with caution due to the mediocre methodological quality of the included trials.

Monoclonal antibody usage strategies for natural products in traditional chinese medicine
Yukihiro Shoyama
July-September 2017, 3(3):18-27
Monoclonal antibodies (MAbs) against natural products with low-molecular weights have become an important tool when combined with other analytical systems. Eastern blotting involves a typical staining system wherein, for example, glycosides can be blotted to a membrane and cross-linked and stained using MAbs. An immunoaffinity column combined with a monoclonal antibody allows a one-step purification of hapten compounds or preparation of a knockout extract that removes only the target hapten molecules from a crude extract. Here, we discuss the application of these extracts. Single-chain variable fragment (scFv) proteins have led to novel assay systems such as fluobodies or antibodies coupled with green fluorescent protein for natural products. A typical novel application of a scFv gene would be in the context of plant breeding; this is designated “missile-type” molecular breeding, intended to increase hapten molecule concentrations in transgenic plants.

Na Yu, Ke-Jian Zhu, Si-Jing Ma, Hao Tang, Xiao-Ning Tan
October-December 2017, 3(4):15-20
Objectives: The objective of this study is to evaluate the effect of the total flavonoids of Clerodendrum bungei (TFCB) on the proliferation, invasion, and metastasis of A549 lung cancer cells through the Wnt signaling pathway. Materials and Methods: A549 cells were transfected with a β-catenin overexpression plasmid and the empty vector pcDNA3.1. The A549 cells were divided into six groups: normal A549 cell group, normal A549 cells with TFCB group, vector control group, vector with TFCB group, β-catenin overexpression group, and β-catenin with TFCB group. We used the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay to detect cell proliferation, a scratch test was used to observe cell migration, and a transwell experiment was employed to evaluate cell invasion. Proteins related to the Wnt pathway were detected with Western blot analysis, including β-catenin, GSK-3 β, P-GSK-3 β, c-Myc, and CyclinD1. Results: The proliferation, invasion, and metastasis of A549 cells were significantly enhanced after being transfected with the β-catenin overexpression plasmid (P < 0.05 or 0.01), accompanied by increased expression of β-catenin, C-Myc, CyclinD1 and reduced expression of Gsk-3 β and P-GSK-3 β. Treatment of cells with TFCB resulted in inhibition of cell proliferation, migration, and invasion; downregulated expression of β-catenin, C-Myc, and CyclinD1; and upregulated expression of GSK-3 β and P-GSK-3 β, especially in the β-catenin overexpression group. Conclusion: TFCB has the potential to inhibit the Wnt/β-catenin pathway by prohibiting the overexpression of β-catenin and regulating its downstream factors.

Qing-Hong Du, Yi-Bo Tang, Wei-Hong Li, Ya Xu, Lin Han, Xu Jia, Tong Zhao
October-December 2017, 3(4):21-25
Objective: To elucidate the protective effect of Gan Shen Fu Fang (GSFF) on liver endothelial cells in common bile duct-ligated (CBDL) rats. Materials and Methods: Cirrhosis was induced by common bile duct ligation. The rats were divided into three groups: sham group, CBDL group, and GSFF group. After 2 weeks of ligation, rats in the GSFF group were administered GSFF. After 4 weeks, the hydroxyproline (Hyp) content of liver tissues was spectrophotometrically determined. The histological changes were evaluated by H and E and Masson staining. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were used to observe the ultrastructural changes in the liver, especially in the liver sinusoidal endothelial cells (LSECs). Results: Hyp synthesis was significantly inhibited by GSFF, which agreed with the results from H and E and Masson staining for liver fibrosis. The TEM observations of CBDL rats revealed reduced hepatocyte microvilli and deposited fibrous tissue underneath LSECs. SEM confirmed the TEM findings and showed that the fenestrae of LSECs decreased and even disappeared in CBDL rats. The morphological results indicated hepatic sinusoid capillarization. GSFF promoted the restoration of fenestrae and reversed hepatic sinusoid capillarization. Conclusion: GSFF can inhibit Hyp synthesis, restore the fenestrae of LSECs, and reverse hepatic sinusoid capillarization in CBDL rats. These results provide a basis for future detailed investigations of the mechanism of action of GSFF in LSECs.

Mohammad K Ashfaq, Mohamed Sadek Abdel-Bakky, Mir Tahir Maqbool, Waseem Gul, Mahmoud A ElSohly
January-March 2018, 4(1):8-14
Background: Artemisinin dimer oxime – dimer molecule synthesized from artemisinin possesses high bioavailability and marked in vitro anticancer activities against solid tumor-derived cell lines, endothelial cell proliferation, migration, and angiogenic processes. Numerous murine models have been developed to study human cancer. The most widely used models are the human tumor xenograft mouse model. Materials and Methods: In this study, human tumor cells (NCI-H640, 1 × 107 in 100 μL) are implanted subcutaneously, or 1 × 107 in 50 μL in the thoracic cavity, in athymic nude mice (nu/nu). The implanted cells were allowed to grow for 10 days before initiation of drug treatment (dimer oxime and topotecan, ip). Tumor volume and thoracic/body weight ratio were recorded. Results: We successfully established subcutaneous and thoracic xenografts with human nonsmall cell lung cancer cell line xenografts in athymic nude mice in only 10 days. Using these models, we attempted treatment of xenografts with topotecan – a known anticancer drug and artemisinin dimer oxime or combination of these two drugs. Combination therapy showed a significant reduction in tumor volume and tumor/body weight. Treatments with combination of topotecan and dimer oxime resulted in the reduced mortality rates in comparison with untreated mice. Conclusions: Xenograft tumor models are useful for preclinical screening of new pharmacophores. From this preliminary study, it appears that combination of dimer oxime and topotecan may be used as chemotherapeutic agents against nonsmall cell lung cancer. Further studies are needed to evaluate other combination treatment regimens as well as the mechanism(s) of action.

Comparison of granules for prescription and classical decoctions by high-performance thin-layer chromatography-fingerprint analysis
Katharina Schiller, Jörg Heilmann, Detlef Manns, Gerhard Franz
January-March 2018, 4(1):1-7
Objective: The so-called granules for prescription have been developed about 20 years ago as a new form of modernizing and simplification of the classical decoction common in Traditional Chinese Medicine (TCM) practice. Due to actual problems in Germany/Europe, which are caused by the lack of quality monographs and judicial classification of granules for prescription, the aim of the study was a comparison of the chemical composition of commercial granules versus decoctions. Taking an example, decoctions, commercial granules, and organic extracts of two well-established TCM herbal drugs, Scrophulariae Radix and Xanthii Fructus, were examined in their specific composition. Methods: Using high-performance thin-layer chromatography (HPTLC) for fingerprint analysis of different batches of herbal drugs and samples from various suppliers of Xanthii Fructus and Scrophulariae Radix were critically examined. The decoctions were prepared according to traditional rules, while the granules were dissolved in water in accordance with actual regulations. Furthermore, organic extracts of the plant material were examined and compared with aqueous extracts. Results: It could be demonstrated, that in some cases, there are remarkable differences in the specific composition between granules from different suppliers, the classical aqueous decoction and the organic extract used for the HPTLC fingerprinting. On the other hand, few examples exist for good comparability of decoctions and commercial granules. Conclusion: After critical evaluation of the above results, it can be questioned, if there is a so-called phytoequivalence between decoctions and commercial granules for prescription used in TCM practice.

An integrated study for the utilization of anthraquinone compounds extract “Heshouwu” In vivo and their comparative metabolism in liver microsomes using UPLC-ESI-Q-TOF/MSn
Sha Chen, Hong-Yu Ma, Zhe Deng, Jun Zhang, Jin-Tang Cheng, Chang Chen, An Liu
January-March 2018, 4(1):21-27
Objective: Anthraquinone (AQ), a major bioactive component of the traditional Chinese medicine HeShouWu, has widespread applications in industry and medicine. The objective of the current study is to explore the differences in the bioavailability of anthraquinones in vivo and the metabolism in liver microsomes. Materials and Methods: In vivo, we used a reliable UPLC-ESI-QqQ-MS/MS method to measure seven AQ compounds in the jugular vein plasma of rats following oral administration of HeShouWu. Furthermore, in order to quantify the bioavailability of AQs in vivo and to further understand the metabolism of these compounds, we compared the in vitro metabolism of AQ in different species with respect to metabolic profiles, the enzymes involved, and catalytic efficiency using liver microsomes from human (HLM), mouse (MLM), rat (RLM), and beagle dog (DLM). Results: We identified two metabolic pathways, including the hydroxylation and glucuronidation of AQ, in the liver microsomes of humans and other species using UPLC-ESI-Q-TOF. We found that substitutions on the AQ ring were crucial to the activity and regioselectivity of its hydroxylation. In general, hydroxylation activity decreased greatly with β-COOH (rhein) and enhanced dramatically with β-OH (emodin). We also found that glucuronidation of the compound emodin-8-O-β-D-glucoside acts as the main isoform in AQ hydroxylation in HLM and DLM. Total microsomal intrinsic clearance values for AQ were greatest in mouse microsomes, followed by those in dog, human, and rat microsomes. Conclusion: The absorption of different anthrquinone compounds varied based on the compound structure, the metabolism types and products of anthraquinones in liver microsomes were different in different species. These findings provide vital information for a deeper unuunderstanding of the metabolism of AQs.

De-Liang Liu, Shu-Fang Chu, Hui-Lin Li, Heng-Xia Zhao, Xue-Mei Liu, Xin Qu, Yi-Nan Zhou, Zhe Chen, Xue-Wen Zhang
January-March 2018, 4(1):28-35
Objective: Our aim was to investigate the correlation between free fatty acid (FFA) spectrum, blood stasis (BS) score, and macroangiopathy in type 2 diabetic patients with or without BS, as well as the possible relationship between BS and lipotoxicity. Methods: A total of 50 type 2 diabetes (T2D) patients with or without BS were enrolled from June to December 2014 in Shenzhen Traditional Chinese Medicine (TCM) Hospital, with 25 patients allocated to each of two groups. Basic information, BS score, blood glucose, blood lipids, etc., were measured for each patient. In addition, we tested the levels of interleukin (IL)-6, tumor necrosis factor α (TNF-α), and IL-18 with enzyme-linked immunosorbent assay. The macroangiopathy status of patients in the two groups was examined by color ultrasound and all factors related to BS scores were analyzed. Gas chromatography-mass spectrometry was used to explore the difference in the serum FFA spectra between the two different groups. In addition, the relationship between FFA spectra, BS scores, and macroangiopathy was analyzed. Results: BS scores, total cholesterol (TC), total triglyceride (TG), low-density lipoprotein cholesterol, IL-6, TNF-α, IL-18, carotid and femoral artery plaque, carotid intima-media thickness, carotid plaque area, and femoral artery plaque area were all significantly increased in T2D patients with BS syndrome (P < 0.05). A positive correlation was observed between age, duration of diabetes, carotid intima-media thickness, carotid plaque area, femoral artery plaque area, and BS score (P < 0.05). A total of 21 fatty acids were found in the serum, and total FFA (TFFA), saturated fatty acid (SFA), lauric acid (C12:0), palmitic acid (16:0), stearic acid (C18:0), arachidonic acid (C20:4n6), behenic acid (C22:0), and lignoceric acid (C24:0) scores were all found to contribute to the difference between FFA spectrums of the two groups; of the fatty acids, C12:0, C16:0, C18:0, C22:0, TFFA, and SFA positively correlated with BS scores as evaluated by Pearson's or Spearman's correlation analysis (P < 0.05). Only SFA entered the regression equation in the multiple linear regression analysis. C12:0, C16:0, C18:0, C20:4n6, TFFA, and SFA were positively correlated with carotid plaque area, whereas linoleic acid (C18:3n3), Cis-5, 8, 11, 14, and 17-eicosapentaenoic acids (C20:5n3) were negatively correlated (P < 0.05). C16:0 was positively correlated with the femoral artery plaque area and C18:3n3, cis-4, 7, 10, 13, 16, and 19-docosahexaenoic acids (C22:6) and nervonic acid were negatively correlated (P < 0.05). Conclusion: Serum FFA spectra were significantly different between T2D patients with BS and those without, and long-chain SFA made the greatest contribution. Serum FFA spectra were correlated with BS scores and diabetic macroangiopathy, which means that lipotoxicity and BS are correlated in T2D.

January-March 2018, 4(1):15-20
Objective: To clone and investigate two dehydrodolichyl diphosphate synthase genes of Tripterygium wilfordii by bioinformatics and tissue expression analysis. Materials and Methods: According to the T. wifordii transcriptome database, specific primers were designed to clone the TwDHDDS1 and TwDHDDS2 genes via PCR. Based on the cloned sequences, protein structure prediction, multiple sequence alignment and phylogenetic tree construction were performed. The expression levels of the genes in different tissues of T. wilfordii were measured by real-time quantitative PCR. Results: The TwDHDDS1 gene encompassed a 873 bp open reading frame (ORF) and encoded a protein of 290 amino acids. The calculated molecular weight of the translated protein was about 33.46 kDa, and the theoretical isoelectric point (pI) was 8.67. The TwDHDDS2 encompassed a 768 bp ORF, encoding a protein of 255 amino acids with a calculated molecular weight of about 21.19 kDa, and a theoretical isoelectric point (pI) of 7.72. Plant tissue expression analysis indicated that TwDHDDS1 and TwDHDDS2 both have relatively ubiquitous expression in all sampled organ tissues, but showed the highest transcription levels in the stems. Conclusions: The results of this study provide a basis for further functional studies of TwDHDDS1 and TwDHDDS2. Most importantly, these genes are promising genetic targets for the regulation of the biosynthetic pathways of important bioactive terpenoids such as triptolide.

Bao-Yue Zhang, Yi-Fu Zheng, Xiao-Cong Pang, Zhe Wang, Hong Ding, Ai-Lin Liu
April-June 2018, 4(2):43-53
Objective: To investigate the network pharmacology of anti-tumor Chinese medicinal formulae and explain the synergistic mechanism of various active ingredients of Chinese medicinal formulae. Methods: We collected the anti-tumor Chinese medicinal formulae and chose several single herbs with the top frequency for further study. The chemical constituents of these herbs were downloaded from databases CNPC and Traditional Chinese Medicine Systems Pharmacology and were analyzed to set up the anti-tumor material basis. The genes regulated by these constituents were retrieved in Traditional Chinese Medicine integrated database and Comparative Toxicogenomics database. Results: We collected 65 anti-tumor Chinese medicinal formulae, and 4 single herbs were selected, including Licorice, Radix astragali, Panax ginseng, and Radix scutellariae, which consist of 172, 70, 293, and 92 known constituents, respectively. The constituent–gene network, protein–protein interaction network, gene–pathway enrichment network, and gene–disease network were constructed. Moreover, molecular docking was employed to clarify the interactions between active constituents and key drug targets (PTG2, epidermal growth factor receptor, peroxisome proliferator-activated receptor gamma, estrogen receptor 1, mammalian target of rapamycin, AKT1, mitogen-activated protein kinase 1 [MAPK1], peroxisome proliferator-activated receptor alpha, and MAPK8). Most of the constituents could act on multiple targets, whose structures mainly belong to alkaloids, flavonoids, and their glycosides, organic acids, or dianthrone, and their representative chemical constituents include narcissus glycosides, rutin, dauricine, scutellarin, baicalin, isoschaftoside, and leucovorin. Conclusion: The network mechanism of the effective constituents from traditional Chinese medicines (TCMs) for anti-tumor therapy was partially uncovered by using statistical methods, network pharmacology methods, and molecular docking methods. This study will provide important information for new drug design with multiple targets for anti-tumor therapy.

Juan Liu, Ti-Ying Chen, Yuan Yuan, Jun-Hui Zhou, Yu-Yang Zhao, Lu-Qi Huang
April-June 2018, 4(2):37-42
Background: NAC, as a unique transcription factor to plants, plays important roles in multiple biological functions, such as regulation of plant growth and development, hormone levels, and responses to various kinds of stresses. However, there is a lack of research of NAC genes in Chinese herbs. Objective: The study aimed to evaluate the potential functions of NAC genes in Scutellaria baicalensis by bioinformatics and expression analysis, and provide evidence of the molecular regulation mechanism involved in flavonoid biosynthesis in S. baicalensis. Methods: The genes of NAC transcription factors in S. baicalensis were obtained from cDNA library and their functions were explored using bioinformatic methods. The NAC genes were screened from the cDNA library of S. baicalensis using BLAST comparison software. Then, the open reading frame (ORF) finder online tool was used to predict the full-length ORFs of NAC genes and their protein characteristics were explored by bioinformatic methods. The expression of NAC genes was then detected by quantitative polymerase chain reaction in different parts of S. baicalensis and different leaves treated by gibberellin GA3 treatment. Results: Six genes of NAC transcription factors were cloned, two of which had complete ORFs. NAC genes cloned in this study were mainly expressed in the flowers of S. baicalensis. The expression levels of NAC2, NAC3, NAC4, NAC5, NAC6 were increased firstly and then decreased gradually after 100 μM GA3 treatment. Meanwhile, some NACs and PAL2 in S. baicalensis showed strong correlation. Conclusion: This study suggested that NACs cloned in this study were mainly regulated the flavonoid biosynthesis in the flowers of S. baicalensis; NAC6 in S. baicalensis might be involved in the regulation of PAL2 transcription and affected the accumulation of flavonoids in the root of S. baicalensis. Our results provided a basis for further understanding the molecular regulation mechanism of flavonoid biosynthesis in S. baicalensis.

Le-Min Xia, Le-Le Cui, Yi-Ling Jiang, Zheng Qin, Mei-Hong Luo
October-December 2017, 3(4):46-50
Background: The “Diagnosis and Treatment Guidelines for Chinese Medicine Internal Common Diseases” issued by the Chinese Institute of traditional Chinese medicine (TCM) offers many methods for the treatment of aplastic anemia (AA). However, there is a lack of corresponding evidence. Objective: The study aimed to evaluate the clinical efficacy of TCM in the treatment of AA, and provide evidence for the development of guidelines for the diagnosis and treatment of AA using TCM. Methods: Data of randomized or semi-randomized control trials of AA treatments with TCM were retrieved, and the selected literature was scored using the Jadad scale. The data were extracted, and RevMan 5.2.6 software was used for the meta-analysis. Results: Two studies on the treatment of AA using Liuwei Dihuang pills combined with compound Zaofan pill were included. The results of the meta-analysis showed that there were no statistically significant differences in the efficacy between Liuwei Dihuang pills combined with compound Zaofan pill and androgen in the treatment of AA (P = 0.65). However, there were less adverse reactions, including liver damage and the hirsutism of women, with the former than the latter (P < 0.05). Other studies on the treatment of AA with TCM did not include reports from clinical trials. Conclusion: TCM had a certain curative effect when used to treat AA. However, the quality of the literature is generally low, and the sample size is small, which makes the validation of the results poor. Further high-quality studies are needed to provide high-level evidence.

Guang-Wei Zhu, Jie Guo, Ya-Jing Li, Lu Luo, Toru Sugita, Takehisa Tomoda
April-June 2018, 4(2):69-76
Objective: The objective of this study is to investigate the inhibitory effect of peony and licorice decoction and its compatibility components on the Nav1.4 voltage-gated sodium channels (VGSCs). Materials and Methods: Writhing test was carried out with ICR mice. Paeonia lactiflora and Glycyrrhiza uralensis group were administrated 0.2 ml of solution of freeze-dried powder dissolved in normal saline with the concentration of 2.94 mg/ml, 1.47 mg/ml, and 0.74 mg/ml using intragastric administration, respectively. Peony and licorice decoction groups were administrated 0.2 ml of solution of freeze-dried powder dissolved in normal saline with the concentration of 5.89 mg/ml, 2.94 mg/ml, and 1.47 mg/ml using intragastric administration, respectively. For electrophysiology studies, each freeze-dried powder was dissolved in DMSO to make 10 mg/ml and 50 mg/ml stock solutions. The electrophysiological recordings were obtained under visual control of a microscope. For UPLC analysis, the freeze-dried powder was dissolved in methanol and then determines the contents of the nine marker compounds. Results: The effect of G. uralensis on incubation period and writhing frequency was significantly better than that of peony and licorice decoction group and P. lactiflora group. The inhibition rate of 50 mg/ml water extracts of the three samples was significantly higher than that of the 10 mg/ml group. Moreover, the water extract of G. uralensis at 50 mg/ml had the strongest inhibitory effect on INav1.4 of the three. Conclusion: The possible mechanism of peony and licorice decoction in relieving spasm and pain is most likely by inhibiting Voltage-Gated Sodium Channel Subtype 1.4.

Objective: The objective of this study is to study the best inclusion technology of Lavender- and fennel-mixed volatile oil by beta-cyclodextrin (β-CD) and characterize the final product thereafter. Methods: Using the saturated water solution method, the volatile β-CD inclusion complex was produced. The effect of volatile oil weight ratio, inclusion temperature and inclusion time on the inclusive quality was studied by measuring the yield of inclusion and inclusion rate of volatile oil as evaluation indexes. The preparation method of inclusion complex was then optimized by the Box-Behnken response surface method. The inclusion complex was characterized by ultraviolet spectrophotometry, thin-layer chromatography, thermogravimetry and differential thermal analysis, and the microscopic imaging method. Results: The optimized conditions were the weight ratio of β-CD to volatile oil was 8.13:1 (g/ml). The inclusion temperature was 44°C. The inclusion time was 1 h. Conclusion: We were able to produce an inclusion complex with high inclusion rate of volatile oil and high yield of inclusion using the preparation method mentioned above. Furthermore, the method can also improve the stability of volatile oil in abnormal savda munziq. This study can provide a good reference for the development of new preparations.

Li-Na Liang, You-Zhi Tang, Wen-Jie Zhan, Jiao Li, Qun-Ying Ma, Jie Liang
April-June 2018, 4(2):62-68
Objective: The objective of this study is to investigate the inhibitory effect of LXHY, a Chinese medicine compound formula, on choroidal neovascularization (CNV) and to find the possible working mechanism. Methods: CNV was induced in C57BL/6 mice by krypton laser and bone marrow-derived cells (BMCs) isolated from enhanced green fluorescent protein (EGFP) transgenic mice were injected through tail vein 0.5–1 h after the laser surgery. The BMC-treated mice were randomly divided into two groups gavaged with either distilled water (DW group) or LXHY formula solution from day 1 after laser surgery. On days 7, 14, and 28 after treatment, histopathologic examination, fundus fluorescein angiography, and choroidal flatmount assay were performed to measure the CNV severity and BMC recruitment. CXCR4 levels in peripheral blood were measured by enzyme-linked immunosorbent assay. Stromal cell-derived factor-1α (SDF-1α), vascular cell adhesion molecule-1 (VCAM-1), and intercellular adhesion molecule-1 (ICAM-1) were detected by immunofluorescent staining. Results: On days 7 and 14 after treatment, CNV lesions in the LXHY-treated mice showed less recruitment of BMCs and were smaller in size compared to DW-treated mice. Histological examination also confirmed less severe CNV lesions in the LXHY group. CXCR4 levels in peripheral blood in the LXHY group were less than that of DW group on days 7 and 14. Moreover, the expression levels of SDF-1α, ICAM-1, and VCAM-1 at the lesion sites in the LXHY group were lower compared with the DW group. Conclusion: This experiment indicated that LXHY formula could inhibit CNV formation and development, probably by inhibiting the recruitment and attachment of BMCs into CNV area.

July-September 2018, 4(3):77-84
Objective: The objective of the study is to investigate the effect of Kangfuxin lotion as adjunctive therapy for treating ulcerative colitis (UC) through a systematic review and meta-analysis of randomized controlled trials (RCTs). Materials and Methods: RCTs comparing Kangfuxin lotion with no treatment, placebo, western medications or combination therapy for treatment of UC were included in this study. Two English and three Chinese electronic databases were searched. All searches ended in December 2017. Data and quality assessment carried out respectively. RevMan 5.2 software (Copenhagen, The Nordic Cochrane Centre, The Cochrane Collaboration, 2014) was used to analyze with effect estimate presented as mean difference (MD), risk ratio (RR) and 95% confidence interval (CI). Results: Fifteen trials with 1050 participants were included in this review. Overall, 13 trials were eligible for meta-analysis. Kangfuxin lotion combined with Mesalazine was better than Mesalazine on clinical cure rate (RR 1.45, 95% CI 1.24–1.70, 7 trials), recurrence rate of UC (RR 0.22, 95% CI 0.07–0.72, 2 trials), or endoscopic mucosal recovery (RR 8.05, 95% CI 2.64–24.57, 2 trials). And Kangfuxin lotion combined with triple live bacteria tablets (Bifidobacterium-Lactobacillus- Streptococcus thermophilus)was superior with regard to symptoms remission rate (RR 5.36, 95% CI 1.73–16.60, 3 trials), endoscopic disease activity score (MD − 2.30, 95% CI − 2.64–−1.96, 1 trial). There were no reports on the serious adverse events of Kangfuxin lotion. Conclusion: Kangfuxin lotion as adjunctive treatment appears more effective than medications alone on clinical cure rate, recurrence rate, endoscopic mucosal recovery and improvement rate of related symptoms.
