OBJECTIVE To estimate the quality markers of antioxidant activity for standard decoction of Schisandrae Chinensis Fructus.METHODS 15 batches of Schisandrae Chinensis Fructus standard decoctions were subjected to quality evaluation by ultra high-performance liquid chromatography(UPLC)based on single-marker(QAMS)method,before being summarized by chemometrics analysis.The antioxidant abilities of 15 batches of samples were determined by DPPH and ABTS methods,while gray correlation analy-sis(GRA)and the partial least squares regression(PLSR)methods were subsequently applied to investigating the relationship between the contents of 8 components and the antioxidant activity.Ultimately,molecule docking was utilized to explore the binding properties between candidate quality markers and the core targets of anti-oxidation,with the experimental verification being executed on the indi-vidual compound by in vitro anti-oxidation.RESULTS There was no remarkable difference between the results of QAMS and external standard method(ESM),with P valued greater than 0.05.And it was speculated that protocatechuic acid,gomisin A,schizantherin B and schisandrin B were the constituents of quality difference.Moreover,the 4 quality variation components were reckoned to be the al-ternative markers on antioxidant according to the results of GRA and PLSR.The molecule docking result also showed that 4 candidate quality markers presented good binding affinity with the antioxidant core targets.The antioxidant capacity was presumably originated from the collaborated effects by multi-components in the standard decoction of Schisandrae Chinensis Fructus.In the interim,protocate-chuic acid exhibited noteworthy antioxidant efficacy with dosage-depended manner in the results of single-compound verification,which was best conformed to the characteristics of quality markers and supposed to be the antioxidant quality marker for Schisandrae Chinensis Fructus standard decoction.CONCLUSION This research predicts the potential antioxidant substances on the basis of content deter-mination by UPLC and in vitro antioxidant assay,but also provides rational foundation for quality assessment on other preparations of Schisandrae Chinensis Fructus.

Constructing a multi-tiered healthcare security system can meet the diverse and individualized healthcare service demand of the general public.Public hospitals,as the main providers of healthcare services in China,effectively integrate with commercial health insurance,which can accelerate the implementation of high-quality healthcare services,promote innovative development,and optimize product coverage and operational efficiency for commercial health insurance,achieving a win-win situation.Taking Shanghai as the research object,it analyzes the supply and demand status of multi-tiered healthcare security in Shanghai based on population characteristics,economic level,healthcare resources,and policy environment.It identifies the difficulties in the current collaboration between public hospitals and commercial insurance.Finally,it proposes exploring the expansion of independent development space for specialized services,improving the level of coordination between commercial insurance institutions and public hospitals in health management services,promoting the management and sharing of data,strengthening the protection of innovative medicines and devices by commercial insurance,in order to promote the coordinated development of commercial insurance and public hospitals.

Metabolic abnormality in type 2 diabetes mellitus(T2DM)can cause damage to the central nervous system,leading to cognitive decline.Neurofilament light chain protein(NFL),as a blood marker of neuroaxonal injuries,is significantly associated with the onset of cognitive impairment and affected by the renal function.It can participate in the development of cognitive impairment in T2DM through inflammation,blood-brain barrier breakdown,interaction between microglia and neurons,and Tau protein phosphorylation.We re-viewed the mechanism of the occurrence and development of NFL-involved cognitive impairment and the correla-tion between NFL and renal function in T2DM,hoping to provide a basis for early diagnosis and treatment of cog-nitive impairment in T2DM patients.
