Objective: To analyze the prevalence status and clustering patterns of risk factors for chronic diseases among adult residents in Rui' an City, Zhejiang Province, so as to provide a basis for formulating strategies for the prevention and control of chronic diseases and implementing risk factor interventions. Methods: A multi-stage random cluster sampling method was used to select residents aged ≥18 years in 5 townships (sub-districts) of Rui' an City as survey subjects from December 2023 to March 2024. Data on basic information, history of major chronic diseases, lifestyle behaviors, height, weight, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. Descriptive analysis was used to analyze the prevalence status of 5 risk factors for chronic diseases. K-means clustering analysis was used to analyze clustering patterns. Results: A total of 3 060 people were surveyed, including 1 476 males, accounting for 48.24%, and 1 584 females, accounting for 51.76%. The median age was 49.00 (interquartile range, 25.00) years. There were 1 275 cases (41.67%) of hypertension, 462 cases (15.10%) of diabetes, and 1 460 cases (47.71%) of dyslipidemia. Insufficient fruit and vegetable intake, excessive salt intake, overweight and obesity, excessive red meat intake, and smoking involved 2 201, 1 878, 1 541, 1 337, and 571 people, with prevalences of 71.93%, 61.37%, 50.36%, 43.69%, and 18.66%, respectively. K-means clustering analysis identified 4 clustering patterns: smoking-insufficient fruit and vegetable intake type (249 people, accounting for 8.20%), low intake type (1 421 people, accounting for 46.75%). high red meat type (245 people, accounting for 8.07%), and high BMI-high salt type (1 118 people, accounting for 36.96%). The prevalences of hypertension and diabetes were higher in adult residents of the high BMI-high salt type, at 56.53% and 20.30%, respectively. The prevalence of dyslipidemia was higher in adult residents of the smoking-insufficient fruit and vegetable intake type, at 59.44%. Conclusions The prevalence of insufficient fruit and vegetable intake among adult residents in Rui' an City is relatively high. The clustering pattern of chronic disease risk factors is dominated by the low intake type. The prevalence of chronic diseases is higher in adult residents of the high BMI-high salt type and smoking-insufficient fruit and vegetable intake type. It is suggested to carry out health education and collaborative intervention of risk factors for different risk groups.

ObjectiveTo address the shortage of high-caliber multidisciplinary professionals in China's rehabilitation engineering field and the prominent issue of "separation between medicine and engineering" in existing curricula, this study introduces the World Health Organization rehabilitation competency framework (RCF) to construct a systematic curriculum system for rehabilitation engineering.

OBJECTIVE To explore the effect and potential mechanisms of berberine on formation of biofilms of clinical methicillin-resistant Staphylococcus aureus(MRSA)isolates.METHODS Totally 95 clinical MRSA iso-lates were collected from Shanghai Eighth People's Hospital from Jan.2023 to Dec.2023.The 14 biofilm forma-tion-related genes in the strains were detected by polymerase chain reaction(PCR)and multiplex PCR,the mini-mum inhibitory concentration(MIC)of berberine was determined by microbroth dilution method,the effect of berberine on resistance of biofilm formation was evaluated by crustal violet staining,fluorescence microscope,Congo red agar plate and extracelluar DNA(eDNA).The transcription levels of 9 biofilm formation-related genes were detected by real-time fluorescent quantitative reverse transcription PCR.RESULTS All of the 95 strains of MRSA carried eno,clfA,clfB and icaA genes,the most widespread gene profile was bbp-eno-ebpS-fnbA-fib-clfA-clfB-icaA-sasG,and 29 strains had the phenotypes with strong capability of biofilm formation.The MIC score of berberine ranged between 64 and 1 024 μg/ml.Berberine with the concentration of 1/2 MIC could inhibit the biofilm formation of MRSA(P＜0.001),and the inhibiting rate of biofilm formation of the MIC ≥512 μg/ml group was higher than that of the MIC≤128 μg/ml group and the MIC 256 μg/ml group(all P＜0.05).The re-sult under the fluorescence microscope showed that the fluorescence intensity of biofilms decreased with the rise of berberine concentration.Berberine could reduce the formation of amyloid fibrils and the release of eDNA,down-regulating the transcription levels of ica A,sasG,ebpS,fib,eno,clfA,clfB,bbp and fnbA genes(P＜0.05).CONCLUSION Berberine may inhibit the biofilm formation of MRSA by downregulating expression levels of related genes,interfering the formation of amyloid fibrils and blocking the release of eDNA,which may provide experimental bases for development of drugs resisting to MRSA biofilms.

Objective : To explore the mechanism of isorhamnetin (Iso) in the treatment of oral squamous cell carcinoma (OSCC) using network pharmacology and molecular docking methods and to verify it in vitro. Methods : The key targets were obtained by constructing the PPI protein interaction network based on the common intersection targets of Iso-OSCC. At the same time, gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) were used to analyze the related signaling pathways of the intersection targets. Iso and core targets were also analyzed through molecular docking and visualization. Colony formation assay and Transwell assay were used to identify the effect of Iso on the proliferation and invasion of Cal-27 cells. Western blot was used to analyze the regulatory effects of different concentrations of Iso on estrogen receptor-1 (ESR1), phosphoinositide-3-kinase regulatory subunit-1 (PIK3R1), Src tyrosine kinase (SRC), and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway proteins. Results: A total of 269 potential intersection targets of Iso-regulated OSCC were obtained. According to the degree obtained by topological analysis, PIK3R1, AKT1, SRC, ESR1, and other core targets were screened out. KEGG analysis showed that 165 signaling pathways were enriched in the intersection targets of Iso-OSCC, among which the PI3K/AKT signaling pathway played an important role in the treatment of OSCC with Iso. Molecular docking results showed that the absolute value of binding energy between target proteins PIK3R1, AKT1, SRC, ESR1, and Iso was high. After Cal-27 cells were treated with Iso, the number of cell colony formations, the number of transmembrane cells, and the expression of PIK3R1, ESR1, SRC, p-PI3K, and p-AKT were negatively correlated with the increase in Iso concentration (P < 0.05). Conclusion Iso can inhibit PI3K/AKT signal transduction and influence the expression of PIK3R1, AKT1, SRC, and ESR1 proteins, thereby inhibiting the occurrence and development of OSCC.
