OBJECTIVE: Coptis chinensis (Huanglian in Chinese, HL) is commonly utilized in clinical settings to counteract dyslipidemia in patients with hot syndrome. Its lipid-reducing efficacy has been consistently demonstrated in high-fat diet (HFD)-induced hyperlipidemic animal models. However, whether HL's efficacy differs in HFD-fed animals with hot or cold syndromes remains unclear. This study aims to discern the variations in the anti-hyperlipidemic effects of HL in HFD-fed mice with hot or cold syndromes. METHODS: HFD-induced C57BL/6 mice were subjected to cold or hot syndrome via two weeks of ice water (0 °C) and levothyroxine sodium (240 µg/kg) treatment, respectively. Then, an aqueous extract of HL was administered to the mice via oral gavage over the following four-week period. Lipid levels in the serum and liver were gauged to determine the lipid-reducing effects of HL. Furthermore, gut microbiota composition was elucidated using full-length 16S rRNA gene sequencing. RESULTS: HL notably reduced lipid levels in HFD-induced hyperlipidemic mice. Its efficacy was amplified in hyperlipidemic mice with a hot syndrome but was markedly reduced in those with a cold syndrome. HL treatment led to a decline in alpha-diversity (characterized by ACE, Chao1, Shannon and Simpson index) of the gut microbiota in both sets of mice but affected specific microbial populations based on the syndrome. Specifically, while HL led to a notable increase in Eubacterium, Robinsoniella, and Lachnoclostridium genera, along with the enhancement of Clostridium innocuum and Bacteroides thetaiotaomicron species across all conditions, it syndrome-dependently stimulated Romboutsia ilealis and Parabaceroides_sp_HGS0025 species in mice with hot syndrome. CONCLUSION HL shows stronger lipid-lowering effect on hyperlipidemic mice with hot syndrome, which is in accordance with its traditional usage in clinic. The therapeutic outcomes of HL are intrinsically tied, at least in part, to its modulatory effects on the gut microbiota, offering fresh insights into the foundational principles of traditional Chinese medicine.

OBJECTIVE To investigate the current status of cleaning and disinfection of medical bedding items in public medical institutions of Liangshan ethnic minority area and analyze the risk of infections so as to provide ba-ses for optimizing the infection control strategies in the ethnic minority area.METHODS On the basis of question-naire survey,onsite sampling method and bacterial isolation and identification technique,a cross-sectional survey was conducted for the current status of cleaning and disinfection of medical bedding items in 15 different grades of public medical institutions of Liangshan ethnic minority area by stratified random sampling method from Sep.2021 to Sep.2023.RESULTS A total of 66 valid questionnaire were recycled,and 540 bedding item samples were col-lected.Totally 93.33％of the medical institutions relied on laundries for centralized cleaning of the medical bed-ding items.The implementation rates of management items such as policy formulation(100.00％)and pre-job training were remarkably higher in the tertiary hospitals than in the secondary and primary hospitals(allP＜0.05).There were no significant differences in the qualified rates of surveillance of microbiological indexes for the medical bedding items among the medical institutions,the qualified rate of surveillance of microbiological inde-xes was highest(71.30％)in the general hospitals and was lowest(61.11％)in the infectious diseases specialized hospital.The qualified rate of surveillance of microbiological indexes was lowest(3.33％)in pediatrics department or internal medicine department,and it raised most remarkably(80.00％)after the disinfection,and there was significant difference(x2=36.274,P＜0.001).CONCLUSIONS The current status of disinfection of the medical bedding items is not optimistic in the medical institutions of Liangshan ethnic minority area.There are the prob-lems such as imperfect system,insufficient equipment and absence of personnel training.It is necessary to com-plete the execution and supervision system for cleaning and disinfection standards,increase the cleaning facilities,promote the use of antibacterial textile and bring in smart management system so as to improve the cleaning and disinfection quality and reduce the risk of hospital-associated infections.
