Objective To investigate the intervention effect and mechanism of LUO's Neiyi Prescription on the proliferation and angiogenesis of eutopic endometrium in rats with endometriosis(EMs)based on hypoxia-inducible factor 1A(HIF1A)/enhancer of zeste homolog 2(EZH2)/anthrax toxin receptor 2(ANTXR2)signaling pathway.Methods SD rats were randomly divided into sham operation group,model group,Danazol group(4.2 g·kg-1),low-dose LUO's Neiyi Prescription group and high-dose LUO's Neiyi Prescription group(15.74,31.48 g·kg-1),eight rats in each group.The rat model of EMs with qi stagnation and blood stasis syndrome was constructed by autologous endometrial transplantation combined with multi-factor intervention.Intragastric administration was given once a day for 28 consecutive days.The pathological changes of endometrial tissue were observed by HE staining.The expression levels of proliferating cell protein 67(Ki67)and platelet endothelial cell adhesion molecule 1(CD31)in endometrial tissue were detected by immunohistochemistry.The mRNA and protein expression levels of HIF1A,EZH2 and ANTXR2 in endometrial tissues were detected by qRT-PCR and Western Blot.The expression levels of YAP1,CD44 and β-catenin in endometrial tissues were detected by Western Blot.Results Compared with the sham operation group,the epithelial cells of the eutopic endometrium of the model group were thickened,the interstitial cells were arranged disorderly,and the inflammatory cells increased.The expression levels of Ki67 and CD31 in endometrial tissues were significantly increased(P＜0.01),the mRNA and protein expression levels of HIF1A and ANTXR2 were significantly increased(P＜0.01),while the mRNA and protein expression levels of EZH2 were significantly decreased(P＜0.01),and the protein expression levels of YAP1,CD44 and β-catenin were significantly increased(P＜0.01).Compared with the model group,the epithelial layer of the eutopic endometrial tissue of the rats in each administration group became thinner,the interstitial disorder and inflammatory infiltration were improved,and the levels of Ki67 and CD31 in the eutopic endometrial tissue were significantly decreased(P＜0.01).The mRNA and protein expression levels of HIF1A and ANTXR2 in the endometrium of rats in the Danazol group and the high-dose LUO's Neiyi Prescription group were significantly decreased(P＜0.05,P＜0.01),and the mRNA and protein expression levels of EZH2 were significantly increased(P＜0.05,P＜0.01).The protein expression levels of YAP1,CD44 and β-catenin in endometrial tissue of rats in each administration group were significantly decreased(P＜0.05,P＜0.01).Conclusion LUO's Neiyi Prescription can play a role in the treatment of EMs by inhibiting the proliferation and angiogenesis of eutopic endometrial cells,and its mechanism may be related to the inhibition of HIF1A/EZH2/ANTXR2 signaling pathway.

OBJECTIVE: Circular RNAs (circRNAs) participate in several important pathological processes and have been used in the diagnosis and treatment of various diseases. This study aimed to investigate the role of circRNAs in neural tube defects (NTDs). METHOD: We characterized circRNA-associated competitive endogenous RNA (ceRNA) networks in brain tissue of low folate -induced NTDs mouse at embryonic day 13.5 by high-throughput sequencing. The expression levels of Circzfp644, miR-20-5p and Gas7 were detected by RT-PCR. Gas7 and Circzfp644 functions were determined by miRNA-mimics and inhibitors in mouse teratocarcinoma cells (F9 cells), and luciferase gene reporter assay was assessed in the F9 cells. In addition, the expression levels of Circzfp644, miR-20-5p and Gas7 were determined by Nanostring in human NTDs tissues. RESULTS: We detected 57 circRNA transcripts, 16 miRNAs, and 148 mRNAs that were significantly dysregulated in NTDs brain tissues compared with their expression levels in control (normal) tissues. Circzfp644 shared miRNA response elements with the growth arrest specific 7 ( Gas7) gene and competitively bound with miR-20-5p to increase the expression of Gas7. Downregulation of Circzfp644 and Gas7 and upregulation of miR-20-5p were found in human NTD tissue. CONCLUSION This study provides new perspectives on the role of circRNAs in nervous system development and the pathogenesis of NTDs.

Uric acid (UA) is the final product of purine metabolism in human body,and its metabolic disorder will induce hyperuricemia (HUA).The occurrence and development of HUA are associated with a variety of pathological mechanisms such as oxidative stress injury,activation of inflammatory cytokines,and activation of renin-angiotensin-aldosterone system.These mechanisms directly or indirectly affect the bioavailability of endogenous nitric oxide (NO).The decrease in NO bioavailability is common in the diseases with high concentration of UA as an independent risk factor.In this review,we summarize the mechanisms by which high concentrations of UA affect the endogenous NO bioavailability,with a focus on the mechanisms of high-concentration UA in decreasing the synthesis and/or increasing the consumption of NO.This review aims to provide references for alleviating the multisystem symptoms and improving the prognosis of HUA,and lay a theoretical foundation for in-depth study of the correlations between HUA and other metabolic diseases.

The ethanol precipitation process of Nauclea officinalis extract was optimized based on the concept of quality by design(QbD). Single factor tests were carried out to determine the levels of test factors. The ethanol volume fraction, pre-ethanol precipitation drug concentration, and ethanol precipitation time were taken as critical process parameters(CPPs). With the comprehensive scores of strictosamide transfer rate and solid removal rate as the critical quality attributes(CQAs), Box-Behnken design was employed to establish the mathematical models and space design between CPPs and CQAs, and the obtained optimal operating space was validated. The optimal operating space included ethanol volume fraction of 65%-70%, pre-ethanol precipitation drug concentration of 22-27 mg·mL~(-1), and ethanol precipitation time of 12 h. Based on the concept of QbD, this study adopted the design space to optimize the ethanol precipitation process of N. officinalis extract, which provided a reliable theoretical basis for the quality control in the production process of N. officinalis preparations. Moroever, this study provided a reference value for guiding the research and industrial production of traditional Chinese medicines.

Aim To investigate the effects of DAP on human rheumatoid arthritis synovial fibroblasts(RA-FLS)and its relationship with endoplasmic reticulum stress(ERS)PERK/ATF4/CHOP signaling pathway.Methods RA-FLS cells were cultured and identified by immunofluorescence assay for Vimentin and CD68.CCK-8 detected(0,5,10,20,30,40,50,60,70)mg·L-1 DAP on the proliferation activity of RA-FLS cells.According to the proliferation activity,the experiment was divided into blank group(Blank),low dose group(L-DAP),medium dose group(M-DAP),high dose group(H-DAP)and high dose+specific inhibitor 4-PBA group(H-DAP+4-PBA).The levels of TNF-α and IL-6 were detected by ELISA.Cell apoptosis was detected by flow cytometry.The invasion and migration of cells were detected by Transwell and scratches assays,and the expressions of endoplasmic reticulum stress-related proteins GRP78,PERK,P-PERK,ATF4,CHOP,Caspase-12,C-Caspase-12 and Bcl-2 were assessed by Western blot.Results CCK-8 results showed that compared with 0 mg·L-1 DAP group,the proliferation activity of each group in 20-70 mg·L-1 DAP group was significantly different(P<0.05),and the proliferation rate corresponding to 0,20,40 and 60 mg·L-1 DAP group was significantly different(P<0.05).This concentration was used as the basis for blank,low-dose,medium-dose,high-dose groups and high-dose+4-PBA experimental grouping.DAP could inhibit the release of inflammatory cytokines IL-6 and TNF-α from RA-FLS cells in concentration,reduce the invasion ability of cells,promote apoptosis,upregulate the expression of PERK,P-PERK,ATF4,GRP78,CHOP,Caspase-12, C-caspase-12 proteins and decrease the expression level of anti-apoptotic protein Bcl-2.Another set of experiments demonstrated that high dose DAP+4-PBA could up-regulate the expression of IL-6 and TNF-α,as well as the invasion of cells,and inhibit the expression of apoptosis and ERs-related proteins.Conclusions Daphresin regulates the secretion of inflammatory factors by activating the PERK/ATF4/CHOP signaling pathway,inhibits the proliferation and invasion of RA-FLS cells,and induces apoptosis,which is expected to be a potential therapeutic pathway for RA.

Pneumonia caused by SARS-CoV-2 has seriously threatened human life and health worldwide and caused a large number of deaths. Viral infection and acute inflammation are important causes of death, so it is particularly important to combine antiviral therapy with anti-inflammatory therapy. Glycyrrhizic acid, the main component of the glycyrrhizic root extract, has a wide range of pharmacological effects as well as high efficiency and low toxicity, its preparation has been widely used in the treatment of chronic hepatitis and other diseases. Glycyrrhizic acid can regulate the expression and release of a variety of cytokines and play a significant anti-inflammatory effect. At the same time, glycyrrhizic acid also showed significant inhibition towards a variety types of viruses. Therefore, the potential application of glycyrrhizic acid as COVID-19 treatment should be explored.

To systematically evaluate the efficacy and safety of traditional Chinese medicine injections combined with antiviral wes-tern medicine in the treatment of influenza by Bayesian network Meta-analysis. Four Chinese databases(CNKI, Wanfang, VIP, CBM) and three English databases(PubMed, EMbase, Cochrane Library) were retrieved by computer for randomized controlled trials(RCT) about the comparison between the combined administration of traditional Chinese medicine injections with antiviral western medicine(or with placebo) and the single administration of antiviral western medicine in the treatment of influenza, or the comparison between two different traditional Chinese medicine injections combined with antiviral western medicine in the treatment of influenza. The retrieval time was from the establishment of the databases to July 2020. Two researchers independently screen out the literatures and extracted the data according to the inclusion criteria and exclusion criteria. The included studies were evaluated by the Cochrane 5.1 bias risk assessment tool, and data analysis was conducted by ADDIS 1.16.8 and Stata 14.0. A total of 49 literatures about 5 061 cases were included finally, involving six traditional Chinese medicine injections, namely Reduning Injection, Xiyanping Injection, Tanreqing Injection, Yanhuning Injection, Qingkailing Injection and Shuanghuanglian Injection. The results of network Meta-analysis,(1)in terms of total effective rate, 6 traditional Chinese medicine injections combined with antiviral western medicine was better than antiviral western medicine alone. In terms of probability sorting, Shuanghuanglian Injection combined with antiviral western medicine ranked first.(2)There was no significant statistical difference in adverse reaction rate among all groups, but Reduning Injection ranked first in the probability sorting, due to the least side effects.(3)In terms of antipyretic time, Yanhuning Injection, Xiyanping Injection and Tanreqing Injection combined with antiviral western medicine was better than antiviral western medicine alone and Xiyanping Injection ranked first in the probability sorting.(4)In terms of cough relief time, Qingkailing Injection and Tanreqing Injection combined with antiviral western medicine was better than antiviral western medicine alone and Qingkailing Injection was superior to Yanhuning Injection. Qingkailing Injection combined with antiviral western medicine ranked first in the probability sorting.(5)In terms of the length of hospital stay, Xiyanping Injection, Tanreqing Injection and Reduning Injection combined with antiviral western medicine was superior to antiviral western medicine alone, and Reduning Injection ranked first in the probability sorting due to the shortest hospital stay. Because of the small quantity and low quality of included studies, the results of this study shall be regarded cautiously and comprehensively. In the future, multi-center, large-sample and clinical randomized controlled trials shall be conducted to verify the results.
