Objective To understand the awareness and willingness of primary medical staff in Songjiang District, Shanghai towards human papillomavirus (HPV) and its vaccines, and to provide references for improving the vaccination willingness of HPV vaccine and primary prevention of cervical cancer. Methods From July to August 2023, a questionnaire survey was conducted among the in-service medical staff in 17 community health service centers in Songjiang District, Shanghai, using the random sampling method. Descriptive analysis, χ² test and logistic regression were used for statistical analysis. Results A total of 951 valid questionnaires were collected during the survey. The awareness rate of HPV among medical staff was 92.74%, and the awareness rate of HPV vaccine was 93.38%. The maximum score for HPV knowledge was 6 points, with an average score of (3.99±1.34) points. The maximum score for HPV vaccine knowledge was 10 points, with an average score of (5.63±1.61) points. 881 (92.64%) medical staff were willing to receive or recommend HPV vaccination. Multivariate analysis showed that concerns about being infected with HPV (OR=2.648, 95% CI: 1.459-4.806), qualified score on HPV vaccine knowledge (OR=1.717, 95% CI: 1.012-2.912), high price burden of HPV vaccine (OR=0.343, 95% CI: 0.157-0.746), and concerns about side effects of vaccination (OR=0.443, 95% CI: 0.243-0.805) were the influencing factors for medical staff's willingness to vaccinate. Conclusion There is insufficient knowledge of HPV and its vaccines among primary medical personnel in Songjiang District, Shanghai. It is necessary to strengthen the continuing education of medical personnel through multiple channels, supplement the HPV-related knowledge system, and eliminate their concerns about vaccines.

Objective:To investigate the mechanism of immunomodulatory effects of umbilical cord mesenchymal stem cells(UC-MSCs)modified by miR-125b-5p on systemic lupus erythematosus(SLE).Methods:The expression level of miR-125b-5p was detected by real-time fluorescence quantitative PCR in UC-MSCs and peripheral blood mononuclear cells(PBMCs)from SLE patients and health checkers.Annexin V-FITC/PI apoptosis detection kit was used to detect the effect of miR-125b-5p on apoptosis of UC-MSCs.MRL/lpr mice in each group were injected with UC-MSCs via tail vein,and T-lymphocyte subsets in the spleen of the MRL/lpr mice were detected by flow cytometry after 5 weeks.The expression levels of interleukin(IL)-4 and IL-17A in serum of MRL/lpr mice were detected by ELISA.Hematoxylin-eosin staining was used to observe the pathological manifestations of the lungs and kidneys of the MRL/lpr mice.Results:miR-125b-5p was significantly down-regulated in PBMCs of SLE patients compared with healthy controls(P＜0.01).Compared with the UC-MSCs group,the expression of miR-125b-5p in UC-MSCs modified by miR-125b-5p group was increased(P＜0.01).The survival rate of UC-MSCs was significantly increased by miR-125b-5p(P＜0.01).Compared with the untreated group of MRL/lpr mice,the expression level of IL-4 in serum was increased(P＜0.05);the expression level of IL-17A was decreased(P＜0.05);the proportion of Th17 cells in the spleen of MRL/lpr mice was decreased(P＜0.05);the inflammatory cells infiltration and micro-thrombosis of lungs and kidneys of MRL/lpr mice were significantly reduced in the UC-MSCs modified by miR-125b-5p treatment group.Conclusion:UC-MSCs modified by miR-125b-5p have immunomodulatory effects on systemic lupus erythematosus.

ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndrome types and influencing factors of protein-energy wasting （PEW） in chronic kidney disease （CKD） undergoing maintenance hemodialysis （MHD）. MethodsAccording to diagnostic criteria， 164 patients with MHD were divided into PEW group and non-PEW group. The clinical data of all patients were collected， including general information such as gender， age， height and weight， disease characteristics such as course， cormobidity， and haemodialysis duration， laboratory indicators such as blood routine， liver function， renal function， electrolyte， blood lipid， grip strength， and the four examinations. Logistic regression analysis was used to find the influencing factors of PEW by taking the clinical indicators with significant differences between the two groups （P＜0.05） as the independent variables， diagnosis of PEW as the dependent variable， and normal values as the reference. ResultsOut of 164 patients with MHD， there were 96 （58.5%） cases in PEW group and 68 cases （41.5%） in non-PEW group. Compared to the non-PEW group，PEW group had increased age， ratios of bedrest， deep vein preservation， edema， and low grip strength， percentages of comorbidities type 2 diabetes， cardiovascular and cerebrovascular diseases，infections and anemia， and levels of alanine aminotransferase and permine amin aminotransferase， as well as decreased body mass index， self-care ratio，internal arteriovenous fistula， red blood cell count， hemoglobin， serum total protein， serum albumin levels （P＜0.05）. The PEW group had significantly higher frequency of poor appetite and digestion， abdominal distension， fear of cold and preference of warmth， weak breathing and fatigue， poor appetite， oliguria， nausea and vomiting than non-PEW group （P＜0.05）. The incidence of both yin and yang deficiency syndrome and damp-turbidity syndrome were significantly higher in the PEW group than the non-PEW group， while that of liver-kidney yin deficiency syndrome and stirring of wind syndrome were lower （P＜0.05）. Logistic regression analysis showed that low BMI （＜22 kg/m²）， inability to take care of oneself， low grip strength，low serum albumin （＜38 g/L）， infection， older age， fear of cold and cold limbs，and poor appetite were the risk factors of PEW in patients undergoing MHD （P＜0.05）. ConclusionThe root syndrome of MHD-PEW patients is both yin and yang deficiency， concurrent with damp-turbidity syndrome. Low BMI， low serum albumin， infection and older age may be the influencing factors of PEW in patients undergoing MHD.

OBJECTIVE: To analyze the composition and metabolites of gut microbiota in septic rats by fecal 16s rRNA sequencing and untargeted metabolomics, and to preliminarily explore the effect and potential mechanism of gut microbiota and its metabolites on inflammatory response and multiple organ damage in sepsis. METHODS: Ten males healthy male Wistar rats were randomly divided into a sham operated group (Sham group) and sepsis model group (CLP group) using a random number table method, with 5 rats in each group. A rat sepsis model was established by cecal ligation and perforation (CLP) method. The animals were sacrificed 24 hours after modeling, the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in peripheral blood were detected by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining was used to observe the pathological changes of lung and kidney tissues, and the pathological scores were evaluated. Fecal samples were collected, and 16s rRNA high-throughput sequencing and non-targeted metabolomics were used to screen microbiota, metabolites and potential signal pathways that may play an important role in disease outcomes. Spearman correlation analysis was conducted to jointly analyze the gut microbiota and non-targeted metabolism. RESULTS: Compared with the Sham group, the degree of pathological damage to lung and kidney tissues in the CLP group was significantly increased (lung tissue score: 3.60±0.80 vs. 0.00±0.00, kidney tissue score: 2.40±0.80 vs. 0.00±0.00, both P < 0.01), the level of IL-6 and TNF-α in peripheral blood significantly increased [TNF-α (ng/L): 248.12±55.98 vs. 143.28±36.57, IL-6 (ng/L): 260.26±39.47 vs. 116.01±26.43, both P < 0.05], the species diversity of intestinal flora of rats in the CLP group was significantly reduced, the relative abundance of Morganella, Bacteroides and Escherichia-Shigella were significantly increased, and the relative abundance of Lachnospiraceae NK4A136, Ruminococcus, Romboutsia and Roseburia were significantly reduced. In addition, the biosynthesis and bile secretion of phenylalanine, tyrosine, and tryptophan in the gut microbiota of the CLP group were significantly increased, while the biosynthesis of secondary bile acids was significantly reduced. There was a significant correlation between differential metabolites and differential microbiota. CONCLUSIONS Sepsis can cause significant changes in the characteristics of gut microbiota and fecal metabolites in rats, which provides a basis for translational research to seek new targets for the treatment of sepsis.
