Distribution Mechanism of Network Modules in Combined Treatment of Liver Cancer with Jiuwei Zhengxiao Granules / 中国实验方剂学杂志

ObjectiveTo explore the distribution mechanism of network modules in the combined treatment of liver cancer with Jiuwei Zhengxiao granules （JWZX） based on the analysis framework of module pharmacology. MethodThe cell experiment and the animal experiment were carried out to investigate the in vitro anti-liver cancer efficacy of JWZX of different concentrations and the effect on the survival time of H22 ascites tumor mice. By virtue of the analysis strategy of modular pharmacology，the distribution characteristics of nine Chinese drugs in the liver cancer disease network modules were investigated based on the constructed liver cancer disease network and module division by MCODE. In this study，the average degree （AD） of the nodes in the modules was used as an index to screen the main modules of the disease，and the intervention of the sovereign drugs，minister drugs，and assistant drugs on the main modules was explored. Finally，the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis was performed on the drug-acted modules by Metascape. ResultAs revealed by the cell experiment，JWZX could significantly inhibit the proliferation of H22 cells. The animal experiment demonstrated that the medium- and high-dose JWZX could significantly prolong the survival time of mice with H22 ascites tumor （P<0.05，P<0.01）. The distribution of targets of JWZX in the liver cancer disease network modules showed that JWZX interfered with tumor necrosis factor （TNF），epidermal growth factor receptor （EGFR），vascular endothelial growth factor A （VEGFA），transcription factor （JUN），tumor protein p53 （TP53），and other 26 targets and 8 modules. The sovereign drug Ginkgo Semen mainly intervened in modules 3 and 8，and the minister drugs such as Centipeda Herba jointly intervened in modules 1，3，5，8，10，and 12. Centipeda Herba and Phyllanthi Fructus intervened in module 7 and module 19 individually. Artemisiae Annuae Herba and other assistant drugs jointly intervened in modules 3，5，10，and 12. KEGG pathway enrichment analysis found that 135 pathways were enriched in 8 modules，and the pathway functions involved 12 categories including cancer，signal transduction，immune system，endocrine system，and amino acid metabolism. The functions of the four major modules involved cancer，signal transduction，and immune system. According to the results of literature verification，the key links of JWZX on the liver cancer disease network and the core mechanism were presumedly related to the inhibition of phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） and hypoxia-inducible factor-1 （HIF-1） signaling pathways，reduction of the immunosuppressive effect in the tumor microenvironment，and improvement of the anti-tumor immune response. ConclusionJWZX possesses pharmacological activity against liver cancer，and the therapeutic efficacy was achieved through the multiple targets，multiple modules，and multiple functions of drugs alone or in combination to intervene in the disease. The present study reduced the complexity of drug-disease target network analysis with module analysis strategy and explored the network module distribution mechanism of JWZX in the treatment of liver cancer，which provides a new idea for interpreting the complex mechanism of prescription compatibility.

State-regulating medicine: an integration of traditional Chinese medicine and biomedicine / 中国中药杂志

Currently available drugs for complex diseases have such limitations as unsatisfactory efficacy, drug resistance, and toxic side effects. Complexity of biological systems is a determinant of drug efficacy. It is not an effective approach to find disturbance strategies for the complicated biological network for complex diseases based on the static topological structures, as biological systems undergo dynamic changes all the time. Supported by profound theoretical basis and rich clinical experience, traditional Chinese medicine(TCM) emphasizes systematic and dynamic treatment depending on changes. Guided by TCM theory in practical treatment, Chinese medicine dynamically and comprehensively regulates the overall state. Therefore, if the dynamic factors are taken into consideration in design, the resultant drugs will be more effective. This study proposes state-regulating(SR) medicine from the perspective of system dynamics, elaborating the concept in terms of the connotations and principle and verifying the feasibility of SR medicine design with the attractor method. Thus, SR medicine is a new concept for drug discovery and design from the aspect of system dynamics, which integrates the TCM focusing on holistic dynamic regulation with biomedicine that features local microscopic research such as molecular mechanisms. The attractor method is a feasible techinical way for SR medicine design.

Exploring efficacy of Chinese medicine injection for promoting blood circulation and removing blood stasis in treatment of acute cerebral infarction based on two complex network analysis methods / 中国中药杂志

This study aims to explore the efficacy of Chinese medicine injections( CMIs) for promoting blood circulation and removing blood stasis for acute cerebral infarction from the perspectives of clinical medication and mechanism of action based on two complex network analysis methods. Firstly,the current 13 kinds of CMIs for acute cerebral infarction were obtained from 2019 List of medicines for national basic medical insurance,industrial injury insurance and maternity insurance with the method of network Meta-analysis. Secondly,with the use of network pharmacology,the mechanisms of top 2 CMIs with the highest therapeutic effect for acute cerebral infarction were explored from two levels including core target and network function enrichment. The result of network Meta-analysis showed Mailuoning Injection was superior to Danhong Injection in terms of total effectiveness rate for neurological deficit score and NIHSS score. The network pharmacology results showed that Mailuoning Injection had more core targets,interaction networks,enriched biological functions and more signaling pathways than Danhong Injection for cerebral infarction. Both two CMIs can play a role in treating cerebral infarction through core targets such as TP53 and NOS3,biological processes such as fibrinolysis,nitric oxide biosynthesis,nitric oxide-mediated signal transduction,negative regulation of apoptosis in endothelial cells and apoptosis process,as well as the signaling pathways such as PI3 K-Akt signaling pathway,HIF-1 signaling pathway and cell apoptosis signaling pathways. The results of pharmacological studies explained their differences in clinical efficacy to a certain extent. A research strategy based on curative effect should be advocated in efficacy evaluation of traditional Chinese medicine,where comparative research on clinical efficacy can be conducted firstly,and then mechanism research based on outstanding effective drugs to better provide references and basis for selection of similar competitive drugs for one disease in the clinical practice.

Retrotransposon insertion polymorphism of the porcine esr gene and its association with production performances of Large White pigs / 生物工程学报

Estrogen receptor (esr) mediates the effects of estrogen on the expression of related genes, thereby regulating the growth and reproduction of mammals. To investigate the effect of retrotransposon insertion polymorphism (RIP) of the porcine esr gene on porcine growth performance, retrotransposon insertion polymorphism of the esr gene were predicted by comparative genomics and bioinformatics, and PCR was used to verify the insertion polymorphisms in different porcine breeds. Finally, the correlation analysis between the genotypes and performance of Large White pigs was conducted. The results showed that four retrotransposon polymorphic sites were identified in the esr1 and esr2 genes, which are esr1-SINE- RIP1 located in intron 2 of the esr1 gene, esr1-LINE-RIP2 and RIP3-esr1- SINE located in intron 5 of the gene, and esr2-LINE-RIP located in intron 1 of the esr2 gene, respectively. Among them, insertion of a 287 bp of SINE into intron 2 of the esr1 gene significantly affected (P<0.05) the live back fat thickness and 100 kg body weight back fat thickness of Large White pigs. Moreover, the live back fat thickness and back fat thickness at 100 kg body weight of homozygous with insertion (SINE+/+) was significantly greater than that of heterozygous with insertion (SINE+/-) and homozygous without insertion (SINE-/-). Therefore, esr1-SINE-RIP1 could be used as a molecular marker to assist the selection of deposition traits in Large White pigs.

Effect of CASC19 on proliferation, apoptosis and radiation sensitivity of cervical cancer cells by regulating miR-449b-5p expression / 中华妇产科杂志

Objective:To investigate the effects of cancer susceptibility candidate gene 19 (CASC19) regulating the expression of microRNA-449b-5p (miR-449b-5p) on the proliferation, apoptosis and radiation sensitivity of cervical cancer cells.Methods:(1) HeLa cells of cervical cancer cell line were cultured. HeLa cells were irradiated with X-ray at different doses (0, 2, 4, 6, 8 Gy, respectively), then the expression level of CASC19 mRNA and miR-449b-5p were detected by real-time quantitative PCR. (2) HeLa cell proliferation, apoptosis, radiation sensitivity (expressed as a survival fraction) and its related protein expression included cyclin D1, cleaved-caspase-3, and histone variant H2AX (γ-H2AX) were examined after different treatment including silencing CASC19 expression, over-expressing miR-449b-5p, down-regulating miR-449b-5p and silencing CASC19 expression. (3) The dual luciferase reporter gene experiment and real-time quantitative PCR technology were used to verify the targeting relationship between CASC19 and miR-449b-5p.Results:(1) With the increase of X-ray irradiation different dose (0, 2, 4, 6, 8 Gy), the expression level of CASC19 mRNA in HeLa cells gradually increased ( F=502.681, P=0.000), and the expression level of miR-449b-5p gradually decreased ( F=202.936, P=0.000).(2) After silencing CASC19 expression or over-expressing miR-449b-5p, the survival rate of HeLa cells was significantly reduced ( P<0.05), the apoptosis rate was significantly increased ( P<0.05), the survival fraction was significantly reduced ( P<0.05), the expression level of cyclin D1 protein was significantly reduced ( P<0.05), and the expression levels of cleaved-caspase-3 and γ-H2AX protein were significantly increased ( P<0.05). After down-regulating miR-449b-5p and silencing CASC19 expression, the survival rate of HeLa cells was significantly reduced ( P<0.05), the apoptosis rate was significantly increased ( P<0.05), the survival fraction was significantly reduced ( P<0.05), the expression levels of cyclin D1 and γ-H2AX protein were significantly increased ( P<0.05), and the expression level of cleaved-caspase-3 was significantly decreased ( P<0.05). (3) Over expression of miR-449b-5p could significantly reduce the luciferase activity of CASC19 wild type (1.00±0.09 versus 0.37±0.05, P<0.01), but there were no significant effect on the luciferase activity of CASC19 mutant type (0.92±0.07 versus 0.94±0.05, P>0.05). After the expression of CASC19 was silenced, the expression level of miR-449b-5p in HeLa cells increased significantly (1.00±0.12 versus 4.84±0.49, P<0.05). After overexpression of CASC19, the expression level of miR-449b-5p in HeLa cells was significantly reduced (1.00±0.09 versus 0.38±0.04, P<0.05). Conclusion:CASC19 in HeLa cells negatively regulates the expression of miR-449b-5p, and down-regulating the expression of miR-449b-5p could partially reverse the effects of silencing CASC19 on HeLa cell proliferation, apoptosis and radiation sensitivity.

Analysis of status quo of RCT outcome indexes in treatment of acute ischemic stroke with traditional Chinese medicine / 中国中药杂志

The purpose of this study was to evaluate the selection situation of outcome indexes in randomized controlled trials of traditional Chinese medicine(TCM) in the treatment of acute ischemic stroke and to provide suggestions for future research. In this study, four Chinese databases and three English databases were searched from January 2017 to June 2019. The randomized controlled trials of traditional Chinese medicine in the treatment of ischemic stroke were selected according to the pre-established selection criteria. Cochrane bias risk assessment tool was used to evaluate the quality of the included studies. A total of 20 651 related articles were searched, and 11 662 ones were left after eliminating the repetitions. Finally, 42 articles were included, including 36 articles in Chinese and 6 articles in English, 40 randomized controlled trials and 2 registration schemes of randomized controlled trials. The results showed that the outcome indexes of 42 randomized controlled trials were mainly divided into seven categories, that is clinical outcome index, blood biochemical index, mental state evaluation index, cerebral hemodynamics index, index of evaluating the degree of carotid artery stenosis, safety indicators and other indicators. The blood biochemical index was the one with highest frequency, followed by the clinical outcome index. TCM syndrome score was used as an indicator of curative outcome in 17 studies. After the analysis, it was found that there were many problems in selecting the outcome indexes for the randomized controlled trials of traditional Chinese medicine in the treatment of cerebral apoplexy. For example, the end point index and hard index were rarely selected as the main outcome indicators, and the vast majority of them were intermediate alternative indexes; recognized curative effect could not be obtained; there were too many kinds of outcome indicators and excessive heterogeneity, hindering the promotion of superior treatment measures of traditional Chinese medicine in clinical practice. Therefore, we should draw lessons from the establishment method of the international core index outcome index set, construct the core index outcome index set of traditional Chinese medicine in the treatment of ischemic stroke, and develop the outcome index set which accords with the curative effect characteristics of traditional Chinese medicine treatment mea-sures to solve the problems effectively.

Ethical review of clinical study on intervention with traditional Chinese medicine in new public health emergencies / 中国中药杂志

High-quality clinical study on traditional Chinese medicine is of great significance to effectively control new public health emergencies represented by outbreaks of infectious diseases and ensure people's health and safety, but it still faces a series of ethical issues. Based on the seven core values of equity, good deeds, effectiveness, respect for individuals, freedom, reciprocity, and solida-rity proposed in the Guidelines for Management of Ethical Issues in Outbreaks of Infectious Diseases, this article emphasizes the characteristics and laws of clinical studies on traditional Chinese medicine. Main points of ethical review of traditional Chinese medicine were summarized in the aspects of overall concept, syndrome differentiation and treatment, prevention before disease onset, cultural value, and clinical basis. Based on the outbreak of coronavirus disease 2019(COVID-19), we collected relevant registered Chinese medicine clinical studies, summarized the core issues of the ethics review for COVID-19, and further improved the traditional Chinese medicine ethics review system and resources, so as to better serve ethical review and scientific studies in public health emergencies.

Effect of CASC19 on proliferation, apoptosis and radiation sensitivity of cervical cancer cells by regulating miR-449b-5p expression / 中华妇产科杂志

Objective@#To investigate the effects of cancer susceptibility candidate gene 19 (CASC19) regulating the expression of microRNA-449b-5p (miR-449b-5p) on the proliferation, apoptosis and radiation sensitivity of cervical cancer cells.@*Methods@#(1) HeLa cells of cervical cancer cell line were cultured. HeLa cells were irradiated with X-ray at different doses (0, 2, 4, 6, 8 Gy, respectively), then the expression level of CASC19 mRNA and miR-449b-5p were detected by real-time quantitative PCR. (2) HeLa cell proliferation, apoptosis, radiation sensitivity (expressed as a survival fraction) and its related protein expression included cyclin D1, cleaved-caspase-3, and histone variant H2AX (γ-H2AX) were examined after different treatment including silencing CASC19 expression, over-expressing miR-449b-5p, down-regulating miR-449b-5p and silencing CASC19 expression. (3) The dual luciferase reporter gene experiment and real-time quantitative PCR technology were used to verify the targeting relationship between CASC19 and miR-449b-5p.@*Results@#(1) With the increase of X-ray irradiation different dose (0, 2, 4, 6, 8 Gy), the expression level of CASC19 mRNA in HeLa cells gradually increased (F=502.681, P=0.000), and the expression level of miR-449b-5p gradually decreased (F=202.936, P=0.000).(2) After silencing CASC19 expression or over-expressing miR-449b-5p, the survival rate of HeLa cells was significantly reduced (P<0.05), the apoptosis rate was significantly increased (P<0.05), the survival fraction was significantly reduced (P<0.05), the expression level of cyclin D1 protein was significantly reduced (P<0.05), and the expression levels of cleaved-caspase-3 and γ-H2AX protein were significantly increased (P<0.05). After down-regulating miR-449b-5p and silencing CASC19 expression, the survival rate of HeLa cells was significantly reduced (P<0.05), the apoptosis rate was significantly increased (P<0.05), the survival fraction was significantly reduced (P<0.05), the expression levels of cyclin D1 and γ-H2AX protein were significantly increased (P<0.05), and the expression level of cleaved-caspase-3 was significantly decreased (P<0.05). (3) Over expression of miR-449b-5p could significantly reduce the luciferase activity of CASC19 wild type (1.00±0.09 versus 0.37±0.05, P<0.01), but there were no significant effect on the luciferase activity of CASC19 mutant type (0.92±0.07 versus 0.94±0.05, P>0.05). After the expression of CASC19 was silenced, the expression level of miR-449b-5p in HeLa cells increased significantly (1.00±0.12 versus 4.84±0.49, P<0.05). After overexpression of CASC19, the expression level of miR-449b-5p in HeLa cells was significantly reduced (1.00±0.09 versus 0.38±0.04, P<0.05).@*Conclusion@#CASC19 in HeLa cells negatively regulates the expression of miR-449b-5p, and down-regulating the expression of miR-449b-5p could partially reverse the effects of silencing CASC19 on HeLa cell proliferation, apoptosis and radiation sensitivity.

Systematic review and trail sequential analysis of preparation of Xiakucao for Hashimoto's thyroiditis / 中国中药杂志

To systemically evaluate the clinical efficacy and safety of oral preparation of Xiakucao with levothyroxine(LT4) on Hashimoto's thyroiditis(HT), so as to provide the evidence for its clinical application in the future. All the included studies were retrieved from four Chinese databases and three English databases from their inception to December 2019. ROB assessment tool of cochrane system and the evidence classification recommended by GRADE were used to evaluate the quality of evidences in all included studies. RevMan 5.3 was used for Meta-analysis of the outcomes. Software TSA 0.9(trail sequential analysis) was used to estimate the sample size for Meta-analysis. The results showed that 11 randomized controlled trials and totaling 1 215 patients were included. Preparation of Xiakucao combined with LT4 was adopted as intervention in experimental group, while patients in control group were treated with LT4 alone. Meta-analysis results showed that as compared with control group, the rate of total efficacy in experimental group was significant improved, including improvement of thyroid function and thyroid autoantibodies, shrinkage of thyroid gland and nodule, and improvement of clinical symptoms such as fatigue and cold intolerance(RR=1.15, 95%CI[1.09, 1.21]). The experimental group significantly decreased the serum level of thyroperoxidase antibody TPO-Ab(SMD=-0.91, 95%CI[-1.40,-0.41]), and reduced the size of left thyroid lobe(MD=-1.46, 95%CI[-1.82,-1.11]), right thyroid lobe(MD=-1.45, 95%CI[-1.96,-0.94]) and isthmus of thyroid gland(MD=-1.08, 95%CI[-1.20,-0.95]). After evaluation based on GRADEpro, the results showed that the evidence quality of all included studies was low or very low. The result of TSA showed that the cumulative sample size had reached the expected value. However, the pooled results may be affected by one study with high bias risk, with not so high effect intensity of evidences. From this review, we can see that in treatment of HT, intervention of preparation of Xiakucao combined with LT4 has advantages on improvement of clinical efficiency, decreasing serum level of TPO-Ab and shrinkage of thyroid gland. However, due to the quality of evidence, more rigorously designed and high-quality trials are needed in the future to verify the clinical efficacy and safety of preparation of Xiakucao in treating HT.
