Abstract:
Objective To evaluate the quality of the clinical trial literatures published on the treatment of COVID-19 with TCM, find out the shortcomings and put forward corresponding suggestions, in order to promote TCM against COVID-19. Methods "COVID-19", "New Coronavirus Pneumonia", "TCM", "Chinese Medicine", "Clinical Trial", "Lianhua Qingwen", "Huoxiang Zhengqi", "Jinhua Qinggan", and other keywords were used to search relevant literatures in CNKI and PubMed database. Among the all the screened relevant literatures on the treatment of COVID-19 with TCM, the literature quality was assessed according to evaluation criteria of clinical trial literatures. Results A total of 463 papers related to the treatment of COVID-19 with TCM were obtained. 440 papers on theoretical research on the network pharmacology mechanism of Chinese medicine treatment of COVID-19 were excluded. Among the 23 articles included in the quality analysis, there are 3 randomized controlled studies, 1 multi-center prospective randomized controlled trial, 2 disease case report trials, and 5 uncontrolled single arm studies, 5 controlled trials and 7 retrospective studies. In the period of more than half a year, although many clinical trial documents of TCM for the treatment of COVID-19 have been published, the clinical trial design reflected in most TCM clinical trials were not standardized. There are problems in "randomness and rationality", such as no control group, no randomization design, only case studies, no blinding method in controlling bias, and insufficient objectivity in the evaluation criteria of efficacy. All of these need to be improved. Conclusion The treatment of new coronavirus pneumonia with TCM still requires more and standardized clinical trial verifications and publications to generate strong evidence-based results, such as adding control groups, increasing sample size, and using blinding methods to increase the credibility of clinical trials.

Abstract:
Objective To investigate the change of biological characteristics after stable knockdown of the coding gene of 3-methylcrotonyl-coenzyme A carboxylase β subunit (MCCC2) expression in DU145 by lentivirus shRNA. Methods Three groups were included in this study. shNC was the control group in which MCCC2 was negatively knocked down in DU145. shMCCC2 was the experimental group in which MCCC2 was knocked down. DU145 was the blank group without any treatment. The expression of MCCC2 was assessed by Western blot and qPCR. The proliferation of DU145 cells was detected by CCK8 assay. The migration ability of DU145 was detected by transwell. The apoptosis of DU145 cells was detected by flow cytometry. Results The expression level of MCCC2 in shMCCC2 group was significantly lower than that in shNC group (0.22 ± 0.02 vs 0.61 ± 0.06, P < 0.001). The proliferation (2.24 ± 0.04 vs 3.13 ± 0.15) and migration (23.96 ± 1.85 vs 49.73 ± 0.63) of DU145 cells in shMCCC2 group was significantly lower than that in shNC group, whereas the apoptosis (12.64 ± 0.30 vs 3.68 ± 0.02) of DU145 cells in shMCCC2 was significantly higher than that in shNC group. Conclusion MCCC2 knockdown significantly inhibited the proliferation and migration, and induced apoptosis of DU145 cells, which indicated that the down-regulation of MCCC2 is correlated with the change of tumor biological characteristics of DU145 cell line and can be a potential target for the treatment of prostate cancer.

Abstract:
Objective To explore the effects of Humulus lupulus L. extract (HLE) and xanthohumol (XN) on preventing glucocorticoid-induced osteoporosis (GIOP). Methods The GIOP model was established by intraperitoneal injection of dexamethasone (DEX). Bone microstructure, bone mineral density and serum biochemical indexes were evaluated by Micro-CT and ELISA kits. The levels of cells proliferation and ALP activity, and the expression of bone formation related proteins were assayed with primary osteoblasts injured by DEX. Results HLE and XN significantly alleviated the bone microstructure damage, enhanced the bone mineral density, and improved the trabecular parameters in GIOP mice. In vitro experiments showed that HLE and XN can prevent bone loss not only by improving cell proliferation and ALP activity, but also through increasing the expression of bone γ-glutamic acid-containing proteins (BGP), bone morphogenetic protein 2 (BMP-2) and runt-related transcription factor 2 (Runx-2). Conclusion This study confirmed that HLE and XN had anti-GIOP effects for the first time. It provides a new resource for the development of anti-osteoporosis medications.

Abstract:
Objective To explore the anti-inflammatory and analgesic mechanism of Yinlian Tongfeng granules by network pharmacology. Methods Three main active components of Yinlian Tongfeng granules were collected from TCMSP database to predict its effective targets. Based on the network information of active components and targets, the anti-inflammatory and analgesic related targets were established by using protein-protein interaction information. The enrichment analysis of KEGG biological pathway and go function enrichment were carried out to construct the active component-target-signal pathway network and explain the main mechanism of anti-inflammatory and analgesic. Results 37 targets were closely related to anti-inflammation and analgesic effects of Yinlian Tongfeng granules, mainly on Prostaglandin endoperoxide synthase 2(PTGS2), interleukin-6 (IL-6), interleukin-10 (IL-10) and tumor necrosis factors (TNF). The mechanism of action may relate to the regulation of nuclear transcription factor B signaling pathway(NF-κB). Conclusion The study predicted the anti-inflammatory and analgesic mechanism of Yinlian Tongfeng granules, and provided theoretical basis for further verification and interpretation of its mechanism.

Abstract:
Objective To explore the potential mechanism of Jiangzhihugan capsule (JZHG) for fatty liver (FL), and to provide a theoretical guideline for the clinical application of JZHG. Methods TCMSP and TCMID databases were used to search for the active components and targets of JZHG. GeneCards and OMIM database were used to search the FL related targets. The intersection method was used to identify the common targets of JZHG and FL. Cytoscape software was applied for the construction of active compounds-targets network map. Protein-protein interaction network was constructed by STRING software. Gene ontology functional enrichment analysis and KEGG pathway enrichment analysis were conducted with Bioconductor database and R software. Results 46 potential active components were screened out from JZHG. 7406 targets were retrieved through GeneCard and OMIM database. 118 genes were obtained from the intersection of component-target and disease-target. These genes were mainly involved with the response to oxidative stress, apoptosis, inflammatory response, hormone resistance and other biological processes. The mechanism was related to PI3K-Akt signaling pathway, human cytomegalovirus infection, microRNAs in cancer, etc. Conclusion The mechanism of active ingredients for FL in JZHG may be due to improving lipid metabolism and reducing liver fat accumulation through anti-oxidative stress and anti-inflammatory effects.

Abstract:
Objective To study the effect of SLCO1B1 521 T>C and APOE gene polymorphisms on the clinical efficacy and safety of atorvastatin in ischemic stroke patients with dyslipidemia. Methods 210 cases of ischemic stroke with dyslipidemia were enrolled from April 2018 to December 2018 to determine SLCO1B1 521 T>C and APOE gene polymorphisms. Patients received atorvastatin 20 mg/d orally. TC, TG, HDL-C, LDL-C levels were measured to evaluate the efficacy 3 months pre-and post- treatment. TBil, ALT, AST, CK levels were assayed with following up adverse reactions to evaluate safety. Results SLCO1B1 521 T>C genotype distribution was TT79.05%, TC19.05%, CC1.90%. E2, E3, E4 allele frequencies of APOE genes were 14.28%, 67.62%, 18.10%. Each genotype conforms to the law of Hardy-Weinberg balance. After three months of medication, there were significant differences in TC, TG, LDL-C, HDL-C changes in patients with different APOE genotypes. No obvious abnormality was found in safety index. The incidence of myalgia in SLCO1B1521 T>C mutant group was significantly higher than that in the wild group (P<0.01). Conclusion Lipid regulation of atorvastatin was affected by APOE gene polymorphism. SLCO1B1521 T>C may be associated with myalgia, the adverse reaction of atorvastatin. The detection of SLCO1B1 and APOE genotyping is helpful for individualized treatment of blood lipids and provides basis for rational use of statins in patients for drug therapy management.

Abstract:
Objective To study the content differences of Dihydromyricetin in Ampelopsis grossedentata from different origins, parts and processing techniques, and improve the therapeutic effects by optimizing the compatibility of Ampelopsis grossedentata with Fructus arctiine. Methods The HPLC separation of Dihydromyricetin was performed on an Agilent ZORBAX SB-C18 column with methanol, 0.05 % phosphoric acid (30∶70) as the mobile phase. The flow rate was 1 ml/min, the detection wavelength was 291 nm, and the column temperature was 25 °C. Compatibility efficacy verification was performed with the inflammation model caused by cotton ball implantation in rats and ear swelling in mice. The net granulomatosis in the rats with cotton ball implantation and the swelling rate of mouse ears were recorded. Results Dihydromyricetin had a good liner recovery between 0.019 9-0.318 mg/ml (r=0.999). The extracted recovery was in the range of 95.04 %-100.4 %. The sample was stable within 24 h. This method had good repeatability. The combination of optimized high-dose Ampelopsis grossedentata with Fructus arctiine resulted in significantly lower net granuloma in rats and ear swelling rate in mice compared to the blank control group. Conclusion This method is simple and accurate. The content of dihydromyricetin varies greatly with different origins, parts, and processing techniques. Among them, the natural sun-dried vine tea in Jiangkou County, Guizhou Province has the highest content. The combination use of Ampelopsis grossedentata and Fructus Arctiine can significantly alleviate the pharyngeal symptoms, reduce the degree of inflammation, and achieve the therapeutic effect of clearing pharynx.
