The advancement of microbiome technologies has facilitated a growing interest in the interactions between urinary microbiota and urinary stone formation. This article systematically reviews the technological evolution, and the reciprocal mechanism of microbiota involvement in lithogenesis and its clinical significance. It specifically highlights the changes within the urinary microbiota of calcium oxalate stone patients, notably a depletion of Lactobacillus populations and an enrichment of pathogenic taxa such as Enterobacteriaceae. Furthermore, it delineates the mechanisms whereby microbes participate in stone formation through metabolic regulation, physical adhesion, and inflammatory processes. The article also explores the influence exerted by distinct stone types on the structural composition and functional dynamics of the urinary microbiota. Integrated multi-omics analyses offer novel perspectives for unraveling the intricate microbiome-host interaction network. This approach is anticipated to facilitate significant advances in developing precision-focused prophylactic and therapeutic strategies for urinary stones from a microecological standpoint.

Objective:To explore impacts of nuciferine(Nuci)on liver fibrosis and inflammatory reaction in cirrhotic rats through p38MAPK-PPARγ/NF-κB signal pathway.Methods:Six SD rats were randomly selected as control(NC)group,other rats were injected with thioacetamide(TAA)into peritoneum at a dose of 200 mg/kg to induce cirrhosis.Rats successfully modeled were randomly grouped into Model group,Nuci group(20 mg/kg Nuci),anisomycin group(5 mg/kg Nuci p38MAPK-PPARγ/NF-κB signal pathway activator anisomycin),and Nuci+anisomycin group(20 mg/kg Nuci+5 mg/kg anisomycin),with 6 rats in each group.The NC group and the Model group were given the same amount of normal saline once a day for 8 weeks.Serum inflammatory index and liver function index were detected by ELISA kits;HE staining was applied to detect pathological changes of liver;Masson staining was applied to detect liver fibrosis;Western blot was applied to detect pathway related proteins levels.Results:In NC group,cell structure was normal,only a small amount of collagen was deposited,no collagen fiber proliferation was observed,and liver lobule was clearly stained.Compared with NC group,hepatocytes in Model group were enlarged,accompanied by inflammatory cell infiltration,and in-creased collagen fiber proliferation,IL-1β,TNF-α,alanine aminotransferase(ALT),IL-6,hyaluronic acid(HA),aspartate amino-transferase(AST),type Ⅲ procollagen(PCⅢ),total bilirubin(TBIL)content,laminin(LN),collagen volume fraction,p-p38MAPK/p38MAPK,p-NF-κB p65/NF-κB p65 proteins levels were significantly increased(P<0.05),PPARγ protein level was significantly decreased(P<0.05).Nuci treatment improved inflammatory cell infiltration and necrosis in liver tissue,levels of IL-1β,IL-6,TNF-α,ALT,AST,TBIL,HA,LN,PCⅢ,collagen volume fraction,p-p38MAPK/p38MAPK,p-NF-κB p65/NF-κB p65 pro-teins were significantly decreased(P<0.05),PPARγ protein level was significantly increased(P<0.05),trend of anisomycin group was opposite to that of Nuci group;anisomycin eliminated therapeutic effect of Nuci on cirrhotic rats.Conclusion:Nuci may reduce liver fibrosis and inflammation in cirrhotic rats by down-regulating p38MAPK-PPARγ/NF-κB signal pathway.

Aim To evaluate the effectiveness and safety of remimazolam tosylate for administering general anesthesia in morbidly obese patients.Methods This clinical trial was conducted at a single center from De-cember 2021 to October 2023.It assessed 108 morbid-ly obese patients(body mass index,BMI≥40)who underwent laparoscopic sleeve gastrectomy.Patients were randomly assigned to either the remimazaolam group(Group R)or the propofol group(Group P)for general anesthesia induction and maintenance.The primary outcome was to compare the incidence of ad-verse events and postoperative recovery characteristics between the two groups.Results During induction pe-riod,the incidence of adverse events was higher in group P,including hypotension(P＜0.01),hypox-emia(P＜0.05),bradycardia(P＜0.01),and in-creased vasopressor requirement(P＜0.05).The time to loss of consciousness and BIS falling to 60 was shor-ter in group P than in group R(P＜0.01).There were no statistically significant differences between the two groups in terms of postoperative quality of recovery(QoR-40 score),24-hour postoperative pain visual an-alogue scale(VAS)scores and morphine consump-tion.In conclusion,remimazolam tosylate,utilized for anesthesia induction in morbidly obese patients,signif-icantly reduced hypotension and hypoxemia compared to propofol,while it could also maintain similar postop-erative recovery quality.Conclusions Remimazolam is effective in reducing the incidence of hypotension and hypoxaemia during the induction period of general anaesthesia in morbidly obese patients and it is compa-rable to propofol in terms of quality of postoperative re-covery.

Objective To understand current epidemic trend of coronavirus disease-2019(COVID-19)in Anhui province in the optimization policy stage,and to analyze the pathogenic characteristics of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)in different population.Methods Using a cross-sectional survey design,from December 19 to 20,2022,an online questionnaire survey was conducted among residents of Anhui province through the official Wechat public accounts of provincial and municipal institutions with high traffic,to collect infor-mation on the incidence and clinic situation of COVID-19.The chi-square test was used to compare the proportion of COVID-19 suspected symptoms in different regions,ages and occupations.Results A total of 69 014 question-naires were distributed and 68 232 valid questionnaires were recovered with an effective rate of 98.97％.The pro-portion of the participants with COVID-19 suspected symptoms in the past 2 weeks was 51.37％,of which 77.88％self-medicated at home.The top three cities were Bozhou,Fuyang and Bengbu.The age group of 15-59 had the highest proportion of COVID-19 suspected symptoms(51.96％).Among various occupations,service providers had the highest proportion of COVID-19 suspected symptoms(61.07％).70.20％of the respondents felt anxious about the infection of SARS-CoV-2 and thought it was more serious than the flu.Conclusion The relatively high number of the infected cases and the anxiety of the people are all challenges faced by Anhui province in the stage of optimizing policies.Under the new situation of the epidemic,it is necessary to continuously monitor the local preva-lent strains and strengthen the monitoring of clinical symptoms of the infected cases,and effectively control the speed of the virus spread through public health policies and various economic and publicity measures,so as not to cause a run on medical resources and excessive excess deaths.

Objective To explore the effectiveness of a nutritional intervention in rescuers who screened positive for depression. Methods A randomized controlled trial design was employed.From June to August,2022,4,460 rescuers were screened using the Self-Rating Depression Scale(SDS),and 1,615 positive cases were identified.Thirty-one volunteers were recruited and randomly divided into a nutritional intervention group and a control group.The intervention group received health education and nutritional intervention(a compound paste therapy primarily composed of red roses and Seville orange flowers),while the control group received psychological education.SDS scores were assessed before and after the intervention. Results There was a statistically significant decline in SDS scores in the nutritional intervention group after the intervention(P<0.05).Furthermore,the SDS scores of the intervention group were significantly lower than those of the control group,both before and after the intervention(P<0.05).No severe adverse reactions were observed during safety evaluation. Conclusion The nutritional intervention effectively reduced the depression scores in rescuers.Early nutritional intervention is recommended for rescuers who initially screen positive for depression.

The objective of this study was to examine the underlying factors and epidemiological traits of a cluster epidemic of cutaneous anthrax in Northern Anhui,to formulate targeted preventive and control strategies.After the epidemic,a rigorous epidemiological investigation was undertaken,including collection of clinical specimens and environmental samples for laboratory analysis.A total of 11 cutaneous anthrax cases were reported,comprising 2 confirmed,6 clinically diagnosed,and 3 suspected cases.These cases were geographically dispersed across a slaughterhouse in Yingzhou District,Fuyang City(5 ca-ses),and a village in Lixin County,Bozhou City(6 cases).All cases were in people engaged in cattle breeding,slaughtering,sales,and other work.The source of infection was traced to cattle purchased from a livestock trading market in another prov-ince.Our findings underscore that this epidemic was a locally transmitted,human-to-human outbreak stemming from the intro-duction of infected animals from another province.Notably,direct contact with infected cattle emerged as the primary mode of infection.

Methods : Sentinel hospital surveillance data and network laboratory etiological surveillance data of influenza⁃like cases (ILI) in Anhui province from 2018 to 2023 were collected by " China influenza surveillance information system" , and the data were analyzed using Excel 2019 and SPSS 25. 0. Results : From 2018 to 2023 , ILI% in Anhui province were 3. 74% , 4. 26% , 3. 53% , 4. 34% , 6. 80% , respectively. The positive rates of influenza virus were 14. 87% , 19. 98% , 0. 12% , 12. 39% and 24. 72% , respectively. There were significant differences in time distribution and age distribution of ILI% and influenza virus positive rates (P < 0. 001) . Influenza mainly occurred from December to March and from June to August in Anhui province. The positive rate of influenza virus detection was the highest among children under 15 years old , which was the main population of influenza cases. The outbreaks had mainly occurred in primary and secondary schools and childcare facilities. Conclusion There are two incidence peaks of influenza each year, one is in winter and spring , another one is in summer. From December to March , from June to August are the critical periods of influenza control and prevention. Children under 15 years old are the key groups and schools are the key places of influenza control and prevention. Continuous influenza surveillance can provide scientific basis for the prevention and control of influenza in Anhui province.

Objective : To analyze the epidemiological characteristics and pathogen spectrum of hand，foot mouth disease (HFMD) in Anhui province from 2015 to 2022，and to provide scientific evidence for prevention and control measures of HFMD． Methods : The surveillance data of hand，foot and mouth disease in Anhui province from 2015 to 2022 were analyzed by descriptive epidemiology.
