BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

To explore the inhibitory effect of ginkgolide B (GB) on MH7A human fibroblast-like synoviocytes (FLS) and its potential mechanism. Firstly, 20 μg/L tumor necrosis factor-α (TNF-α) was pretreated with MH7A to establish a cell model of arthritis. After incubation of MH7A cells with various concentrations of GB, CCK-8 assay, Transwell assay, and flow cytometry (FCM) were separately used to detect cell viability, cell invasion, and cell apoptosis rate and cell cycle; Real-time quantitative PCR and Western blot assay were performed to detect the apoptosis- and cycle-related gene transcriptions and protein expressions, respectively. The results showed that compared with the control group, GB dose- and time-dependently suppressed cell viability to a greater extent; GB significantly reduced cell invasive ability and increased cell apoptosis rate and proportion of G0/G1 phase in MH7A cells, along with increased transcription levels of Bcl-2-associated X protein (Bax) and p21 mRNA and decreased transcription levels of Bcl-2, myeloid cell leukemia 1(Mcl-1), protein kinase B (PKB; AKT), IP3K, Cyclin D1 and cyclin-dependent kinase 4 (CDK4) mRNA; GB remarkably increased expression levels of Bax, p21, and cleaved-Caspase 3 protein and decreased expression levels of Bcl-2, Mcl-1, p-AKT, p-PI3K, Cyclin D1, and CDK4 protein, with decreased ratios of p-PI3K/PI3K, p-AKT/AKT, and Bcl-2/Bax. In conclusion, GB blocks the G1-to-S cell cycle transition, suppresses cell viability and cell invasion and induces cell apoptosis of MH7A human RA-FLS via suppressing the PI3K/AKT signaling pathway.

PURPOSE: This study aims to identify the prevalence and risk factors of military training-related abdominal injuries and help plan and conduct training properly. METHODS: This questionnaire survey study was conducted from October 2021 to May 2022 among military personnel from 6 military units and 8 military medical centers and participants' medical records were consulted to identify the training-related abdominal injuries. All the military personnel who ever participated in military training were included. Those who refused to participate in this study or provided an incomplete questionnaire were excluded. The questionnaire collected demographic information, type of abdominal injury, frequency, training subjects, triggers, treatment, and training disturbance. Chi-square test and t-test were used to compare baseline information. Univariate and multivariate regression analyses were used to explore the risk factors associated with military training-related abdominal injuries. RESULTS: A total of 3058 participants were involved in this study, among which 1797 (58.8%) had suffered training-related abdominal injuries (the mean age was 24.3 years and the service time was 5.6 years), while 1261 (41.2%) had no training-related abdominal injuries (the mean age was 23.1 years and the service time was 4.3 years). There were 546 injured patients (30.4%) suspended the training and 84 (4.6%) needed to be referred to higher-level hospitals. The most common triggers included inadequate warm-up, fatigue, and intense training. The training subjects with the most abdominal injuries were long-distance running (589, 32.8%). Civil servants had the highest rate of abdominal trauma (17.1%). Age ≥ 25 years, military service ≥ 3 years, poor sleep status, and previous abdominal history were independent risk factors for training-related abdominal injury. CONCLUSION More than half of the military personnel have suffered military training-related abdominal injuries. Inadequate warm-up, fatigue, and high training intensity are the most common inducing factors. Scientific and proper training should be conducted according to the factors causing abdominal injuries.

Objective:To analyze the situation of rodents carrying Hantavirus and the genetic and evolutionary characteristics of the virus in Zibo city, Shandong province in 2022, and provide reference for the scientific prevention and control of hemorrhagic fever with renal syndrome (HFRS).Methods:Real-time quantitative PCR (RT-qPCR) was used to detect hantavirus (HV) nucleic acids in rodent lung tissues and identify HV genotypes. Each nucleic acid fragment was designed to amplify various gene fragments by segment, and the whole genome of Hantavirus was sequenced by second generation sequencing. Sequence assembly was performed using SeqMan 7.1.0.44, a subprogram of DNAStar. Sequence alignment and evolutionary analysis were conducted using MEGA 7.0 and BioEdit software.Results:A total of 270 host animals were captured in this survey. Among them, 13 rodent lung samples tested positive for Hantavirus, resulting in a virus-positive rate of 4.8%. The full-genome sequences of four hantavirus strains were successfully obtained, all identified as Seoul virus (SEOV) genotype. Four Hantavirus-positive samples showed high nucleotide sequence homology in the M gene and belonged to the SEOV S3 subtype. These strains exhibited high similarity with those from Hebei, Liaoning, and Beijing. The amino acid sequences of the nucleoprotein and glycoprotein immunogenic epitopes were identical to those of the vaccine strain Z37.Conclusions:This study successfully determined the full genome sequences of four hantavirus strains from Zibo city, Shandong province. The genotypes are primarily SEOV, with the subtype being S3. The homology of genes within the same subtype is high, with no significant variations observed. The alignment of immune epitopes in key proteins suggests that the current vaccine may provide protection against locally circulating strains, but further in-depth research is still required.

Objective:To understand the epidemiological characteristics of severe fever with thrombocytopenia syndrome (SFTS) in Shandong province from 2010 to 2022, analyze the trends in morbidity and mortality, and provide a scientific basis for the prevention, control, diagnosis, and treatment of SFTS.Methods:The data on SFTS cases and deaths were retrospectively collected through the China Disease Control and Prevention Information System′s infectious disease surveillance system and the Shandong province all-cause mortality surveillance system. Descriptive epidemiological method was used for epidemiological analysis, and the Joinpoint regression model was applied to analyze trends in morbidity and mortality.Results:From 2010 to 2022, 6 714 SFTS cases were reported in Shandong, with an average crude incidence rate (CIR) and age-standardized incidence rate (ASIR) of 0.52/100 000 and 0.43/100 000, respectively. Among these, 1, 064 cases died within 30 days of onset, with an average crude mortality rate (CMR) and age-standardized mortality rate (ASMR) of 0.08/100, 000 and 0.06/100 000, respectively, and an average case fatality rate of 15.85%. The average incidence rates for males and females were 0.52/100 000 and 0.53/100 000, respectively, with no statistically significant difference ( P>0.05). The average annual mortality rate for males (0.09/100 000) was higher than that for females (0.08/100 000), and the average annual case fatality rate for males (17.21%) was higher than that for females (14.48%), with statistically significant differences ( P<0.05); 93.95% of the cases were over 45 years old, and 86.56% of the deaths were over 60 years old. Both cases and deaths were primarily among farmers, accounting for over 85% of the total. From 2010 to 2022, the incidence rate of SFTS in Shandong showed an overall upward trend, with an average annual percentage change (AAPC) in CIR of 23.58% and an AAPC in ASIR of 19.97%, P<0.05. The mortality rate of SFTS cases in Shandong from 2010 to 2022 showed a continuous and significant upward trend, with a CMR AAPC of 27.64% and an ASMR AAPC of 22.70%, P<0.05. SFTS incidence and mortality in Shandong exhibited clear seasonality, with high occurrence from May to October, primarily concentrated in the Jiaodong Peninsula and the hilly areas of central Shandong. The number of affected counties increased in a wave-like pattern, expanding from 6 in 2010 to 79 in 2021 for cases and from 2 in 2010 to 53 in 2022 for deaths. Conclusions:From 2010 to 2022, the incidence and mortality of SFTS in Shandong showed an upward and expanding trend, with a particularly heavy disease burden among middle-aged and elderly farmers.

Objective:To evaluate the safety and feasibility of double-port laparoscopic cholecystectomy (LC) combined with transcystic common bile duct (CBD) exploration using ultrafine choledochoscopy on patients with gallbladder stones and common bile duct stones.Methods:Clinical data of 35 patients undergoing double-port LC combined with transcystic CBD exploration using ultrafine choledochoscopy in Anhui No.2 Provincial People’s Hospital from December 2021 to June 2024 were retrospectively analyzed, including 8 males and 27 females, aged (45.8±18.1) years. In all patients, the diameter of the gallbladder duct was greater than 3 mm, the maximum diameter of the stones was less than 10 mm, and the number of stones was less than 5, and the gallbladder ducts were normal. Magnetic resonance cholangiopancreatography (MRCP) was used to measure the diameter of CBD, the number and the maximum diameter of stones. The operative time, intraoperative blood loss, postoperative anal exhaust time, postoperative hospital stay and complications (including abdominal infection, biliary tract infection, bile leakage, bleeding, etc.) of all patients were analyzed. The incidence of bile duct stenosis, residual stone or stone recurrence were followed up by telephone or outpatient review.Results:MRCP measurement indicated that the common bile duct diameter of patients was (8.1±1.3) mm. Single CBD stone occurred in 27 cases (77.1%, 27/35), and the mean maximum diameter of CBD stones was (3.9±1.3) mm. All patients successfully underwent the procedure. The operative time was (80.1±10.9) min, the intraoperative blood loss was (25.5±10.2) ml, the recovery time of postoperative anal exhaust was (17.3±4.7) h, and the postoperative hospital stay was (2.5±0.6) d. There were no complications such as abdominal and biliary tract infection, bile leakage and bleeding. All patients were followed up for 1-30 months, with a median follow-up time of 12 months. No biliary stricture, residual stones or recurrence occured during the follow-ups.Conclusion:In selected cases, double-port LC combined with transcystic CBD exploration using ultrafine choledochoscopy could be safe and feasible, with less trauma, quick recovery and short operative time.

Aim To study the therapeutic effect of al-licin on senna-induced diarrhea in mice and to explore the underlying mechanism.Methods Forty-eight C57BL/6J mice were randomly divided into six groups:control,model,loperamide positive control group(2 mg·kg-1),allicin low-dose group(6 mg·kg-1),allicin medium-dose group(12 mg·kg-1)and allicin high-dose group(18 mg·kg-1).Except for the con-trol group,the diarrhea model was induced in the other groups by intragastric administration of senna leaf ex-tract.After drug administration,several diarrhea indi-ces were measured:the rate of loose stools,diarrhea index,accumulated frequency of loose stools at differ-ent time points within 5 hours,and small intestine pro-pelling rate.Serum levels of TNF-α and IL-6 were de-tected by ELISA.Serum NO content was determined u-sing the Griess method.The activities of SOD and CAT,as well as MDA content in the ileum and colon,were measured.The pathological changes and the ex-pression of mRNA related to intestinal barrier proteins in the ileum and colon were evaluated using HE stai-ning and RT-qPCR.Results Allicin improved diar-rhea symptoms in mice induced by senna leaf.It re-duced the rate of loose stools,diarrhea index,cumula-tive number of loose stools in five hours,and the intes-tinal propulsion rate.Allicin also protected the intesti-nal mucosa,decreased serum TNF-α and IL-6 levels,and lowered MDA content in the intestines.It in-creased serum NO levels and enhanced SOD and CAT activities in the intestines.Additionally,allicin upreg-ulated the mRNA expression of AQP1,AQP4,and ZO-1 in intestinal tissues.Conclusions Allicin has a significant therapeutic effect on senna-induced diarrhea in mice.The underlying molecular mechanisms may involve anti-inflammatory and antioxidant effects,in-creased NO content,and upregulation of mRNA ex-pression of aquaporins and tight-junction proteins.

Objective:To investigate the efficacy and safety of transurethral water vapor thermal therapy(WVTT)using the Rezūm system for benign prostatic hyperplasia(BPH)in the real world.Methods:A total of 181 patients with BPH were recruited from the Second Affiliated Hospital of Nanjing Medical University from August 2022 to December 2023,of whom 173 patients were treated with WVTT using the Rezūm system,while 8 patients were treated with WVTT combined with TURP.They were followed up at 1,3,and 6 months postoperatively to assess changes in the IPSS,QoL,Qmax,IIEF-5,and the occurrence of any complications.Results:All 181 surgeries in this group were successfully completed.The operation time of the Rezūm system was(4.6±1.4)mi-nutes.The postoperative indwelling catheterization time was(8.0±2.1)days.With a follow-up of at least 6 months,there was a significant decrease in PV,IPSS and QoL,and a remarkable increase had been found in Qmax as well(P＜0.05).There was no sig-nificant difference in IIEF-5 before and after the operation(P＞0.05).In this groups of patients,postoperative complications mainly included 95 cases(52.5％)of gross hematuria,6 cases(3.3％)of retrograde ejaculation,5 cases(2.8％)of urethral stricture,4 cases(2.2％)of prostatitis,and 10 cases(5.5％)of urinary tract infection.Four cases(2.2％)underwent surgical retreatment for BPH after surgery.Conclusion:In the real world,the use of Rezūm thermal steam ablation system for the treatment of BPH has sat-isfactory short-term effect,short surgical time,and significant improvement in IPSS,QoL,Qmax,which does not adversely affect sexu-al function.
