OBJECTIVE: To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12. RESULTS: In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred. CONCLUSIONS GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI. (Registration No. ChiCTR1800014291).

OBJECTIVE To clarify the core content of traditional Chinese medicine （TCM） policy in the provinces of China， so as to provide reference for optimizing the structure of the policy system of traditional Chinese medicine in China and assisting the inheritance and innovation of TCM industry in various regions. METHODS The websites of directly affiliated organs in 31 provinces， excluding Hong Kong， Macao and Taiwan， were retrieved to collect the TCM policies released from 2000 to 2021. The importance of keywords in the TCM policies of each province was measured based on term frequency-inverse documentation frequency （TF-IDF） keyword extraction method， and the similarities and differences were analyzed among TCM policies. RESULTS & CONCLUSIONS A total of 99 documents related to TCM policies of various provinces were obtained in this study， most of which were released after 2016. The theme of national TCM policy covered four aspects： building TCM talent team， perfecting TCM service system， strengthening TCM resource management and promoting TCM industry innovation. The TF-IDF values of “medical institutions”“traditional Chinese medicine”“medical treatment” were higher than other keywords in each province， indicating that the provinces paid more attention to the construction of TCM service system and the management of TCM resources than other aspects. Anhui and Jiangsu， Beijing and Henan， Hubei and Jilin， Hubei and Tianjin， and Hubei and Yunnan had the more degree of similarity in TCM policies， which all contained 16 of the same keywords. Therefore， the above regions should be encouraged to strengthen exchanges and cooperation and realize mutual promotion and joint development. Among all the keywords whose importance ratio was greater than 0.2，“ Tibetan medicine” was unique to Qinghai and Tibet，“ disease type” was unique to Guangdong， and the TF-IDF value of “supervision and management” in Beijing was higher， indicating that the emphasis of TCM policy formulation in different provinces was various. Meanwhile， the top 10 keywords of TF- IDF value in all provinces did not have words related to financial input， and the TF-IDF values of “informatization” in most provinces did not rank at the top. It is suggested to increase financial input or encourage social financing， and add “Internet+new business” in the field of TCM.

OBJECTIVE: To investigate the correlation between the human epidermal growth factor receptor-2-related genes (HRGs) and survival prognosis of bladder cancer and to construct a predictive model for survival prognosis of bladder cancer patients based on HRGs. METHODS: HRGs in bladder cancer were found by downloading bladder tumor tissue mRNA sequencing data and clinical data from the cancer genome atlas (TCGA), downloading HER-2 related genes from the molecular signatures database (MsigDB), and crossing the two databases. Further identifying HRGs associated with bladder cancer survival (P < 0.05) by using single and multi-factor Cox regression analysis and constructing HRGs risk score model (HRSM), the bladder cancer patients were categorized into high-risk and low-risk groups accor-ding to the median risk score. Survival analysis of the patients in high- and low-risk groups was conducted using R language and correlation of HRGs with clinical characteristics. A multi-factor Cox regression analysis was used to verify the independent factors affecting the prognosis of the patients with bladder cancer. The area under the curve (AUC) of the receiver operating characteristic curve (ROC) of HRSM was calculated, and a nomogram was constructed for survival prediction of the bladder cancer patients. Analysis of HRSM and patient immune cell infiltration correlation was made using the TIMER database. RESULTS: A total of 13 HRGs associated with patient survival were identified in this study. Five genes (BTC, CDC37, EGF, PTPRR and EREG) were selected for HRSM by multi-factor Cox regression analysis. The 5-year survival rate of the bladder cancer patients in the high-risk group was significantly lower than that of the patients in the low-risk group. High expression of PTPRR was found to be significantly and negatively correlated with tumor grade and stage by clinical correlation analysis, while EREG was found to be the opposite; Increased expression of EGF was associated with high grade, however, the high expression ofCDC37showed the opposite result. And no significant correlation was found between BTC expression and clinical features. Correlation analysis of HRSM with immune cells revealed a positive correlation between risk score and infiltration of dendritic cells, CD8⁺T cells, CD4⁺T cells, neutrophils and macrophages. CONCLUSION HRGs have an important role in the prognosis of bladder cancer patients and may serve as new predictive biomarkers and potential targets for treatment.

Experimental animals have made important contributions to human medical research and life and health. It is known that the development of laboratory animal science in Japan has been relatively rapid in the past few decades, providing important support for the development of the world's experimental animal field. Therefore, it is of great significance to understand the management mode and resource storage situation of Japanese experimental animals, analyze the advantages of Japanese experimental animal development, and propose suggestions to strengthen the high-quality development of experimental animals in China. Through literature research, the authors first analyzed the management system of experimental animals in Japan, including regulations and policies, research funding management, experimental animal management, talent cultivation, and standard and normative systems. Then, the current status of experimental animal research in Japan was summarized, including experimental animal resources, major research institutions, and production enterprises. On this basis, it was found that the field of experimental animal research in Japan currently exhibits characteristics such as a complete policy system, flexible management methods, rich resource reserves, and large-scale industrial development. Finally, by comparing the existing problems in China, suggestions for the development of experimental animal technology in China are proposed: (1) drawing on the legal management method of experimental animals in Japan, strengthening and improving the legislation and management model of experimental animals in China; (2) increaseing investment in scientific research funds, playing the role of research institutions, societies and industries, and promoting the incremental construction and industrial development of experimental animal resources.

Objective:To explore the potential synergistic protective mechanism of Glycyrrhizae Radix et Rhizoma-Granati Pericarpium formula compound by using the methods and tools of network pharmacology，and provide a basis for the modernization of traditional Chinese medicine（TCM） compounds and the discovery of new drugs. Method:Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） was used to obtain the active components of Glycyrrhizae Radix et Rhizoma-Granati Pericarpium formula and their corresponding targets. The obtained targets were input to the UniProt database to inquire the gene names corresponding to the targets. By searching the CTD database，Genecards database and OMIM database of disease-related websites，the anti-sunburn targets were obtained. The interaction of the active targets was analyzed with online STRING database to screen the predicted core targets. The gene ontolog（GO） gene function enrichment analysis and Kyoto encyclopedia of genes and genomes（KEGG） pathway enrichment analysis of the predictive targets were performed by using DAVID database. Cytoscape 3.6.1 software was used to make "drug-component-target" network diagram，"protein-protein interaction" network diagram and "component-target-pathway" network diagram. Online website Draw Venn Diagram was used to show the relationship between disease targets and drug predicted targets. R Studio software was used to draw the functional enrichment analysis diagram of GO gene and KEGG pathway. Molecular docking between the active ingredients and the core targets was performed using GOLD software. Result:The 16 active compounds were collected，such as liquiritin，glycyrrhizin，kaempferol and quercetin. The active components mainly acted on 5 core targets：protein kinase B1（AKT1），interleukin（IL）-6，vascular endothelial growth factor（VEGFA），tumor necrosis factor（TNF） and tumor suppressor gene （TP53） and played a role in anti-sunburn effect primarily through these pathways such as hepatitis B，pathways in cancer，toxoplasmosis，chagas disease（American trypanosomiasis），and TNF signaling pathway. Conclusion:Based on the method of network pharmacology，the present study has preliminarily explored the anti-sunburn targets and pathways of Glycyrrhizae Radix et Rhizoma-Granati Pericarpium formula，and further verified the characteristics of multi-component and multi-target treatment of diseases in TCM，so as to provide certain scientific ideas for the modernization research of Chinese herbal compound prescriptions.

Objective:Compare the anti-tumor effect and mechanism of Liushenwan and realgar (As₄S₄) on human endometrial cancer cells JEC. Method:The release of As in Liushenwan and As₄S₄ was measured by atomic absorption spectrometry. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used for cell proliferation, and cell migration was measured by Transwell assay. Flow cytometry and Western Blot were used to determine apoptosis and DNA damage. Result:The dissolution of As in Liushenwan was 17.4%, and that of As₄S₄ was only 1.6% according to atomic absorption assay. With the same content of As, compared with the As₄S₄ group, the cell viability in the 3，10 mg·L^-1 Liushenwan groups was decreased (P<0.05), the early apoptosis rate was significantly increased in 0.25，0.5，1 mg·L^-1 Liushenwan groups (P<0.05), the rate of cell migration was decreased in 1 mg·L^-1 Liushenwan group (P<0.05), the expressions of cleaved cysteinyl aspartate-specific proteinase-3 (cleaved Caspase-3), cleaved cysteinyl aspartate-specific proteinase-7 (cleaved Caspase-7), cleaved poly ADP-ribose polymerase (cleaved PARP), phosphorylated histone (p-H₂AX), phosphorylation of checkpoint kinase 2 (p-CHK2) and ataxia-telangiectasia mutated (ATM) were increased in 1 mg·L^-1 Liushenwan group (P<0.05), while the expression of phosphorylation of ataxia-telangiectasia mutated rad3-related (ATR) was decreased in 1 mg·L^-1 Liushenwan group (P<0.05), with no significant changes in the expressions of cysteinyl aspartate-specific proteinase-3 (Caspase-3) and cysteinyl aspartate-specific proteinase-7 (Caspase-7). Conclusion:With the same content of As, both Liushenwan and As₄S₄ could inhibit JEC cell proliferation and migration, and induce cell apoptosis and DNA damage. Liushenwan has a stronger effect than As₄S₄. It is suggested that there are other components in Liushenwan with an anti-tumor effect in cooperation with As.
