Objective To investigate the association of interferon (IFN) γ gene polymorphisms and risk and prognosis of HPV cervical infection.Methods PCR-ASP was used for detectiug IFN-γ rs2430561 polymorphism in 179 HPV positive patients and 328 HPV negative normal controls.Results The frequency of A allele of 63.7％ (228/358) was significantly higher than the frequency of T allele of 36.3％ (130/358) in HPV positive group (P =0.045).The frequencies were 41.3％ (74/179) in AA genotype and 14.0％ (25/179) in TT genotype,women carrying AA genotype increased the risk of HPV infection compare with those with TT genotype (OR =1.784,95％ CI:1.031-3.088,P =0.039).During follow-up,the rate of HPV positive again in AA genotype was 83.8％ (62/74),while TT genotype was 20.0％ (5/25).In the analysis of Kaplan-Meier,the cumulative HPV negative rates of AA,TA and TT genotype exhibited significantly different (P =0.008).The cumulative HPV negative rate of AA genotype was the lowest (1.1％-5.9％).Conclusions IFN-γ rs2430561 polymorphisms confer the susceptibility to HPV infection.Women with AA genotype exhibited higher risk of infection and inclined to be continuous status and recurrence after HPV infection.

The classical prescription Yangweitang， derived from Zhengzhi Zhunsheng， is specialized in treating syndromes of chill and fever due to exogenous pathogens， inner-cooling， and malaria， and it has been included in the Catalogue of Ancient Classical Formulas （the First Batch） published by the National Administration of Traditional Chinese Medicine （TCM） in 2018. Through bibliographical research， the relevant ancient books and modern documents were systematically sorted out， and it was found that there were many prescriptions related to the Yangweitang from Zhengzhi Zhunsheng. They were interwoven with Yangweitang from Zhengzhi Zhunsheng and widely used in clinical practice. In order to clarify their history and evolution， this paper combed the historical origin of Yangweitang and its related prescriptions and conducted textual analysis on key information such as semantic composition， herb origin， processing method， and efficacy. A total of 896 pieces of data on Yangweitang from Zhengzhi Zhunsheng were collected. 26 pieces of effective data were included after the screening， involving 17 ancient TCM books. Then， a total of 28 pieces of data on prescriptions related to the Yangweitang from Zhengzhi Zhunsheng were included， involving 23 ancient TCM books for reference. The textual analysis showed that Yangweitang originated from the Renshen Yangweitang recorded in Taiping Huimin Heji Jufang in the Song dynasty. Based on the original formula， medical experts from later generations have modified it into many different versions. A comparative analysis showed that Yangweitang from different generations had similar compositions， and the herb origin and processing method were basically clear. The recommended prescriptions are as follows： 37.3 g of Pinelliae Rhizoma Praeparatum Cum Alumine， Magnoliae Officinalis Cortex（fried with ginger juice）， and frying with rice water Atractlodis Rhizoma， 27.98 g of Citri Exocarpium Rubrum， 18.65 g of Pogostemon cablin leaf， Tsaoko Fructus， Poria， and Ginseng Radix et Rhizoma， and 9.33 g of Glycyrrhizae Radix et Rhizoma. They could be ground into a coarse powder， with 14.92 g for every dose， and they could be orally taken after being decocted with 450 mL of water， 7 g of fresh ginger， and 2 g of Mume Fructus to 270 mL in warm conditions. Yangweitang from Zhengzhi Zhunsheng has the effect of warming the middle and releasing the external， and it can treat many syndromes including spleen and stomach disharmony caused by chill and fever due to exogenous pathogens and inner-cooling， as well as all kinds of malaria. Modern clinical applications mainly focus on chronic atrophic gastritis and other digestive system diseases.

【Objective】 To explore the role and mechanism of TRPC6 in apoptosis of glomerular mesangial cells (HBZY-1) induced by endoplasmic reticulum stress (ERS). 【Methods】 The experiment groups were classified as follows: normal control (NC), thapsigargin (TG), TG+SKF96365, and TG+TRPC6 siRNA groups. Transcription and protein expressions of TRPC6 and ERS related proteins (GRP78 and Caspase12) were detected by qRT-PCR and Western blotting. Additionally, cell apoptosis was measured by flow cytometry and Hoechst33258. Finally, Fluo-4 AM Ca²⁺ imaging technique was used to determine changes of intracellular calcium ( [Ca²⁺] i) by laser scanning confocal microscope. 【Results】 Morphological changes of apoptotic cells were characterized by nuclear enrichment or nuclear fragmentation, and the apoptosis rate was increased after TG stimulation. The expressions of TRPC6 and ERS related proteins (GRP78 and Caspase12) were elevated in TG group compared with NC group (P<0.05). Pre-incubation of HBZY-1 cells with SKF96365 and TRPC6 siRNA decreased cell apoptosis (P<0.05). The entry of [Ca²⁺] i also increased after TG stimulation (P<0.05). The expressions of TRPC6, GRP78 and Caspase12 were downregulated compared with TG group after treatment with SKF96365 and TRPC6 siRNA accompanied by decreased [Ca²⁺] i (P<0.05). 【Conclusion】 Taken together, this study suggests that inhibition of TRPC6 can alleviate TG-induced HBZY-1 cell apoptosis.

End-stage renal disease (ESRD) patients undergoing outpatient hemodialysis (HD) and home peritoneal dialysis (PD) are high risk population of severe and critical types caused by SARS-CoV-2 infection. In order to improve the quality of diagnosis and treatment in dialysis patients with SARS-CoV-2 infection, we wrote this recommendation for primary care clinicians. During the epidemic period of SARS-CoV-2 infection, all patients should be instructed to strengthen self-management. Once the SARS-CoV-2 infection was found in dialysis patients, early stratified management should be carried out within 72 hours after the first positive nucleic acid or antigen test results, which includes early antiviral therapy, early recognition, and transferring severe patients from community or primary hospital to a referral hospital promptly. Guidance for dietary and sports rehabilitation after SARS-CoV-2 infection should also be started as soon as possible.
