This study explores the role and related molecular mechanism of Tianxiangdan (TXD) Capsules in ameliorating atherosclerosis (AS) by regulating GPER (G protein-coupled estrogen receptor) to inhibit NLRP3 inflammasome-mediated pyroptosis. Eight ApoE-/- mice were randomly selected and fed a normal diet as a blank control group, while the remaining ApoE-/- mice were induced with a high-fat diet to establish an atherosclerosis model. These mice were randomly divided into the following groups: model group, atorvastatin intervention group (3.03 mg/kg), TXD Capsules high-dose group (1.092 g/kg), medium-dose TXD group (0.546 g/kg), low-dose TXD group (0.273 g/kg), and medium-dose TXD plus GPER inhibitor (1 mg/kg) group. The effects of TXD Capsules on AS through GPER regulation and inhibition of NLRP3-mediated pyroptosis were evaluated by measuring the serum lipid profile, performing enzyme-linked immunosorbent assays, conducting histopathological analyses, and Western blot. The results showed that TXD significantly reduced serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and inflammatory cytokine levels while increasing high-density lipoprotein cholesterol (HDL-C) levels. TXD also reduced aortic plaque area and lipid deposition. In addition, TXD significantly upregulated GPER expression in aortic tissues and inhibited NLRP3 expression and pyroptosis. These effects were reversed by the GPER inhibitor. In conclusion, TXD may inhibit NLRP3 inflammasome-mediated pyroptosis by upregulating GPER expression, thereby alleviating inflammatory responses in the atherosclerotic microenvironment and exerting vasculoprotective effects.

Objective To build the theoretical system model and research assessment indicators for equalization of basic medical and health services of both urban and rural residents.This aims at providing a theoretical and empirical basis for advancing basic medical health system covering rural and urban residents.Methods Literature research and Delphi expert consultation are used to build the indicator model and structure.The extremal standard method,health resources sharing by geography method,Gini coefficient method and other statistical analysis were used for an empirical analysis and test in an eastern provincial capital city.Results The indicator system comprises three dimensions of opportunity,process and result,as well as seven second-level indicators of health financing,resource allocation,accessibility etc.and twenty-seven third-level indicators.The grand mean value of the urban and rural regional indicators for H city in 2010 was calculated as 63.53,while the mean values for urban and rural were 74.75 and 45.58 respectively.Conclusion The assessment indicators focus on three combinations:basic public health services and basic medical services,service supply and demand,as well as the number and quality of services.This approach can help with the assessment of equalization of basic medical and health service for urban and rural areas and policy making.

Objective To study the chemical constituents of the medicinal fungus Shiraia bambusicola.Methods Chromatography on silica column and preparative HPLC were used to purify the compounds;Spectroscopic methods including 1H-NMR,13CNMR,and MS were used to elucidate their structures.Results Nine compounds were isolated and identified as 3,6,8-trihydroxy-l-methylxanthone(1),3,8-dihydroxy-6-methoxy-1-methylxanthone(2),2,3,6,8-tetrahydroxy-l-methylxanthone(3),3,4,6,8-tetrahydroxy-l-methylxanthone(4),pregn5(10)-en-3?,17?,20?-triol(5),macrosphelide A(6),(+)-griseofulvin(7),griseophenone A(8),and 11,11′-dideoxyverticillin A(9).Conclusion Compounds 1-9 are obtained from the fungus S.bambusicola for the first time.
