This study was aimed at exploring novel auxiliary diagnostic biomarkers for brucellosis and their potential miR-NA-mRNA regulatory networks.High-throughput sequencing was used to compare miRNA expression differences in serum ex-osomes between patients with brucellosis and healthy controls.Subsequently,RT-qPCR was used to validate the expression of significantly upregulated exosomal miRNAs.The diagnostic value of these miRNAs was assessed with ROC curves,and bioin-formatics analyses were performed to investigate the potential roles of the miRNAs in brucellosis infection.The ROC curve a-nalysis indicated that the area under the curve for exosomal hsa-miR-11400(P＜0.05),hsa-miR-199a-5p(P＜0.05),and hsa-miR-148a-5p(P＜0.05)was 0.79,0.81,and 0.74,respectively.A total of 465 differentially expressed miRNAs and their tar-get genes were predicted,including 25 immune-related target genes,most of which were closely associated with cancer-related proteoglycans,NF-kappa B signaling pathways,and IL-17 signaling pathways.The constructed differentially expressed gene network indicated that the immune genes PLXNA2,IL17RA,PRKCA,CD22,ACVR1B,and CBL might be regulated by hsa-miR-199a-5p and hsa-miR-148a-5p.These findings suggest that exosomal miRNAs might serve as auxiliary diagnostic indicators for brucellosis.Our exosomal miRNA-mRNA regulatory network provides new insights into the pathogenesis and treatment of brucellosis.

Objective To explore practical pathways for the connotation quality control of Zhuang medical records by le-veraging the reform of DRG-based medical insurance payment systems as an opportunity,thereby enhancing record quality and fostering the coordinated development of ethnic medicine with modern medical insurance payment systems.Methods By analy-zing the requirements imposed by the DRG-based payment reform on the quality management of Zhuang medical records,a quality control management system focused on the connotation quality control of these records was established.A scoring standard for the connotation quality of Zhuang medical records,supplemented by DRG,was developed.Dynamic quality control was implemented through a combination of information-based intelligent review and expert manual review to ensure rectification.Results Key in-dicators,such as the qualification rate of the first page of medical records,the A-level rate of inpatient records,and the DRG en-rollment rate,showed significant improvements.The documentations of surgical and procedural records were standardized,and the records of ward rounds and case discussions by senior physicians were comprehensive and detailed,accurately reflecting the diagnostic and therapeutic methods and outcomes of Zhuang medicine.Conclusion The DRG-based quality control model for Zhuang medical records effectively aligns medical insurance payment with the unique characteristics of ethnic medicine,offering a replicable model for the quality management of medical records in ethnic medicine institutions under DRG-based reforms.

This study was aimed at identifying the pathogenic bacteria responsible for the death of a young tiger at the Fujian Meihua Mountain South China Tiger Breeding Research Institute.Tissue samples from the lungs,liver,and intestines of the deceased tiger were collected,and the bacteria were cultured inasterile environment.The bacterial strains were characterized according to their morphological and molecular biological properties,including assessment of virulence genes and antibiotic resistance genes,mouse lethality tests,and antibiotic susceptibility evaluations.A predominant bacterial strain isolated from the liver of the deceased tiger was identified as enterotoxigenic Escherichia coli(ETEC)strain Tiger22513F.Phylogenetic analysis of the 16S rRNA gene revealed that the Tiger22513F strain exhibited close genetic similarity to the reference strain ETEC(MF919609.1),with 99.9%nucleotide similarity,and resided on the same evolutionary branch.The Tiger22513F strain contained 11 antibiotic resistance genes(tetA,sul1,sul3,cmlA,floR,blaTEM,blaSHV,blaCMY-2,qnrA,qnrS,and qnrD)along with five virulence genes(VT1,fyuA,tsh,iucD,and ST).Mouse lethality tests indicated significant pathogenicity toward mice,affecting primarily the lungs,liver,and intestines.Antibiotic susceptibility testing demonstrated that this strain exhibited resistance to various classes of beta-lactam antibiotics,as well as quinolones and aminoglycosides.This investigation successfully isolated a multi-drug resistant enterotoxigenic Escherichia coli strain with pronounced pathogenicity from the liver of a deceased tiger;thus providing valuable scientific insights for clinical diagnosis,as well as prevention and control measures,against ETEC infections in South China tigers.

Objective To explore influencing factors in diagnosing stump vaginal lesions by comparing the clinical data of patients with vaginal wall resection after total hysterectomy.Methods This retrospective study included patients who underwent vaginectomy due to stump vaginal lesions[including high-grade intraepithelial lesion(HSIL)or cancer]in Obstetrics and Gynecology Hospital,Fudan University between Jan 1,2013 and Sep 30,2022.The diagnosis was confirmed based on pathology results after vaginal stump resection,then patients were categorized into HSIL group and vaginal cancer(VC)group.We analyzed the differences in clinical features between the groups and evaluated the diagnostic value of various indicators for vaginal cancer.Additionally,within the VC group,patients whose colposcopic biopsy showed HSIL while whose pathology upgraded to invasive cancer after stump colpotomy were classified as the high-grade pathologic invasive cancer group(HC group).We then compared the HSIL group and the HC group to assess the predictive value of each index for pathological escalation.Results Significant differences were observed between the HSIL and VC groups in terms of age,etiology of previous hysterectomy,proportion of clinical symptoms,proportion of abnormal physical examination findings,proportion of abnormal imaging findings,proportion of papillary lesions,proportion of vaginal roof lesions,and squamous cell carcinoma antigen(SCCA)(P<0.05).However,there were no significant differences in fertility,previous hysterectomy,or HPV infection rate.Abnormal physical examination and imaging findings demonstrated better diagnostic performance(AUC>0.7).The proportion of vaginal apex lesions was significantly higher in the HC group compared with the HSIL group(P<0.05).Conclusion Previous hysterectomy for cervical cancer,presence of clinical symptoms,abnormal physical findings,abnormal imaging manifestations,and lesions at the vaginal apex are significant influencing factors in the diagnosis of vaginal stump carcinoma.Although colposcopy remains the primary diagnostic method,vaginal resection should be considered to rule out invasive carcinoma when high-risk factors exist,even if colposcopic biopsy pathology suggests HSIL.

Objective To analyse the clinical efficacy and safety of acupuncture combined with intermittent catheterisation in treating postoperative urinary retention after radical surgery for cervical cancer,and provide reference for the clinical treatment of postoperative urinary retention.Methods A retrospective analysis was conducted based on the clinical data of patients who underwent radical hysterectomy for cervical cancer at Obstetrics and Gynecology Hospital,Fudan University,from Sept 2019 to Dec 2021 and subsequently developed urinary retention.The patients were treated with a combination of acupuncture and intermittent catheterization.We observed residual urine volume,duration of acupuncture treatment,and urinary tract infection status to evaluate the effectiveness and safety of the acupuncture combined with intermittent catheterization regimen.We examined the relationship between treatment duration and various factors such as age,pathological type,surgical-pathological staging,surgical method,pre-treatment catheter indwelling time,pre-treatment residual urine volume,presence or absence of postoperative radiotherapy and chemotherapy,pre-existing urinary tract infection,and whether ureteral stenting was performed,in order to analyze the factors affecting the treatment duration.Results A total of 156 patients were reviewed.After treatment,132 cases had a post-treatment residual urine volume<100 mL,7 cases had a volume of 100-200 mL,and 15 cases had a volume>200 mL.Two cases still had great difficulty in urination after treatment,resulting in an overall effectiveness rate of 89.1%.No significant adverse events occurred in the patients.The treatment duration ranged from 2 to 17 days,with an average treatment time of 6.2 days.The treatment duration was a correlated with the preoperative indwelling catheter duration,residual urine volume and postoperative radiotherapy.Conclusion Acupuncture combined with intermittent catheterisation in treating urinary retention after radical surgery for cervical cancer has good efficacy,short treatment time and no obvious adverse effects,and can be an option for treating postoperative urinary retention.

Objective:To investigate the effects of combination therapy with aqueous extract of corn silk(CS)and training on exercise capacity and glycolipid metabolism in mice with metabolic syndrome(MS).Methods:In this study,db/db mice were used as the animal model of MS.The mice were administered aqueous extract of CS via gavage and subjected to different intensities of training for 12 weeks(3 months).The specific experimental design was as follows:24 db/db mice were randomly divided into four groups on average:negative control group(NC),aqueous extract of CS group(CS),aqueous extract of CS+moderate-intensity training group(CS+MT),and CS aqueous extract of CS+high-intensity training group(CS+HT).The maximum running speed,forelimb grip strength,body weight and fasting blood glucose of mice were measured before and after treatment.After the intervention,oral glucose tolerance test(OGTT)and insulin tolerance test(ITT)were conducted to assess glucose metabolism,while serum triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C)levels were measured to evaluate lipid metabolism.Results:After 3 months of intervention,there were significant differences in the maximum running speed and forelimb grip strength among the four groups(P＜0.05).The maximum running speed and forelimb grip strength of CS group,CS+MT group and CS+HT group were higher than those of NC group(P＜0.05).The CS+MT group exhibited higher forelimb grip strength,and the CS+HT group showed higher maximum running speed and forelimb grip strength compared to the CS group(P＜0.05),while no significant difference was found between the CS+MT and CS+HT groups(P＞0.05).Significant differences in body weight were observed among the four groups after 3 months of intervention(P＜0.05).Specifically,the CS+MT and CS+HT groups exhibited significantly lower body weight compared to both the NC and CS groups(P＜0.05),with the CS+MT group having the lowest body weight(P＜0.05).Fasting blood glucose levels also differed significantly among the groups after 2 and 3 months of intervention(P＜0.05).The CS,CS+MT,and CS+HT groups had lower fasting blood glucose levels compared to the NC group(P＜0.05),with the CS+MT and CS+HT groups showing the lowest levels(P＜0.05).No significant difference was found between the CS+MT and CS+HT groups(P＞0.05).After 3 months of intervention,significant differences in the area under the curve(AUC)of OGTT and ITT were observed among the four groups(P＜0.05).The AUC of OGTT and ITT were significantly lower in the CS,CS+MT,and CS+HT groups compared to the NC group(P＜0.05).The CS+MT and CS+HT groups exhibited the lowest AUC values for both OGTT and ITT(P＜0.05),with the CS+MT group showing the lowest AUC for OGTT(P＜0.05).Significant differences in serum lipid levels were observed among the four groups after 3 months of intervention(P＜0.05).TG,TC,and LDL-C levels were significantly lower,while HDL-C levels were higher in the CS,CS+MT,and CS+HT groups compared to the NC group(P＜0.05).The CS+MT group had the lowest TG levels and the highest HDL-C levels compared to the CS+HT group(P＜0.05),with no significant differences in TC and LDL-C levels between these two groups(P＞0.05).Conclusion:Aqueous extract of CS combined with different intensity training can significantly improve the exercise capacity and glycolipid metabolism of MS mice and reduce body weight,especially CS combined with MT treatment is more effective in improving lipid metabolism.In addition,when combined with HT,aqueous extract of CS can also play an auxiliary role in reducing the side effects of high-intensity exercise and improving the therapeutic effect.
