Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

ObjectiveTo analyze the annual publication volume， prolific research institutions， and research hotspots in the field of shared decision-making （SDM） by utilizing CiteSpace software based on a literature review， predicting the future research focus and development direction in this area. MethodsAn advanced search was conducted in the China National Knowledge Infrastructure （CNKI） and the Web of Science Core Collection databases， with the search timeframe limited to 2004—2024. Scientific knowledge mapping analysis was performed using CiteSpace software. ResultsFrom 2004 to 2024， the volume of publications on SDM research has shown an increasing trend both domestically and internationally. In China， SDM research was mainly focused on nursing， oncology， and other fields， whereas internationally， the emphasis was on patient participation， risk communication， and the application of decision-making support tools. In China， research institutions were primarily nursing schools and specific departments in affiliated hospitals， while internationally， SDM research was concentrated in North America. Keyword analysis showed that the research hotspots in China have gradually shifted from technical topics such as decision-making trees to the practical application of patient participation and decision-making support tools， while international research has earlier moved into the areas of SDM and artificial intelligence-supported decision-making tools. ConclusionThe research hotspots of SDM， both domestically and internationally， have gradually shifted from theoretical exploration to clinical practice and technological applications. In the future， with the deeper integration of artificial intelligence and big data technologies， SDM research in China will focus more on optimizing decision-making support systems and enhancing patient participation. Promoting the localization of SDM practices， fostering multidisciplinary collaboration， and strengthening policy support will be key directions for future research.

Objective To investigate the effect of intravenous flurbiprofen axetil on the incidence and severity of catheter-related bladder discomfort(CRBD)after transurethral resection of the prostate(TURP).Methods The elderly patients undergoing TURP under general anesthesia were enrolled,and randomly divided into two groups:flurbiprofen axetil group(group F)and control group(group C).Ten minutes before the end of surgery,group F was given 50 mg of flurbiprofen axetil intravenously,group C was given an equal amount of 0.9％sodium chloride injection.The primary outcome indicator was the incidence of moderate to severe CRBD immediately after entering the resuscitation room(T0).Secondary indicators included the incidence and severity of CRBD at 1 h(T1),2 h(T2),and 6 h(T3)after entering the resuscitation room,the amount of sufentanil used within 24 hours after surgery,postoperative NRS score,flurbiprofen axetil-related and analgesic adverse reactions 24 hours after surgery,and patient satisfaction.Results A total of 90 patients were included and each group was 45 patients.The incidence of moderate to severe CRBD at T0 was significantly lower in group F than that in group C(8.9％vs.33.3％,P=0.004).The incidence of CRBD in T1,T2,and T3 was lower in group F than in group C(P＜0.05).The incidence of mild CRBD at T3 in group F was lower than that in group C(P＜0.05).The incidence of moderate to severe CRBD at T1 and T2 in groups F was lower than that in group C(P＜0.05).The amount of sufentanil used in group F at 24 hours after surgery was significantly lower than that in group C(P=0.001).The pain scores in group F at T0,T1,T2,and T3 were lower than those in group C(P＜0.05);The postoperative patient satisfaction score in group F was higher than that in group C(P=0.001).However,there were no significant differences between the two groups in postoperative anesthesia resuscitation time and 24-hour adverse reactions incidence(P＞0.05).Conclusion Intravenous flurbiprofen axetil can safely and effectively reduce the incidence and severity of CRBD after TURP.It can significantly relieve pain,reduce sufentanil use,and have high clinical application value.

Objective To describe the clinical features of patients with primary sclerosing cholangitis(PSC)in China based on a nationwide multicenter patient cohort,and to investigate the risk factors for prognosis.Methods A retrospective cohort study was conducted among the patients with a confirmed diagnosis of PSC based on the electronic medical record system of seven grade A tertiary hospitals across the country,and related data were extracted.The Mann-Whitney U test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.The Kaplan-Meier method was used to estimate liver transplant-free survival,and the log-rank test was used for comparison of survival rate between PSC patients with different features.The Cox regression model was used to identify independent risk factors for the prognosis of PSC patients and the interactions between key factors.Results A total of 107 patients were enrolled,among whom 55.6%(55/99)had large-duct PSC and 29.0%(31/107)had comorbidity with inflammatory bowel disease(IBD).The positivity rate of anti-neutrophil cytoplasmic antibody(ANCA)was 32.9%(24/73),and 50.0%(40/80)of the patients had an increase in IgG/IgM.The median symptom-to-diagnosis interval was 1 year(<1-4.0),and 38.3%(41/107)of the patients had progressed to decompensated cirrhosis at the time of diagnosis.The median liver transplant-free survival time was 114 months(95%confidence interval[CI]:62-166),with a 5-year survival rate of 65.7%.The multivariate analysis showed that an increase in total bile acid(TBA)(hazard ratio[HR]=1.006,95%CI:1.002-1.010,P=0.001)and a prolonged symptom-to-diagnosis interval(HR=1.252,95%CI:1.059-1.480,P=0.009)were independent risk factors for prognosis.The interaction analysis showed that compared with the female patients with TBA<50 μmol/L,both male and female patients with TBA≥50 μmol/L had a significant increase in the risk of liver transplantation or death(male:HR=16.563,95%CI:2.103-130.449,P<0.001;female:HR=17.009,95%CI:2.113-136.934,P<0.001),and compared with the patients with an age of<45 years and a TBA level of<50 μmol/L,the patients with an age of≥45 years and a TBA level of≥50 μmol/L had a significant increase in the risk of liver transplantation or death(HR=10.729,95%CI:1.325-86.859,P=0.026).Compared with the female patients with an symptom-to-diagnosis interval of≤2 years,the male patients with a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.825,95%CI:1.725-13.644,P=0.003),and compared with the patients with an age of<45 years and a symptom-to-diagnosis interval of≤2 years,the patients with an age of<45 years and a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.983,95%CI:1.366-18.173,P=0.015).Conclusion Compared with the reports from Western countries,large-duct PSC is also the main type of PSC in China,but with a relatively low proportion,and there is also a relatively low proportion of patients with IBD or positive ANCA.An increase in TBA and a prolonged symptom-to-diagnosis interval are independent risk factors for prognosis,with significant interactions with age and sex.This suggests that early screening and intervention should be enhanced to improve prognosis.

Objective:To understand the pathogenic composition and epidemiological characteristics of febrile respiratory syndrome (FRS) in elderly people aged 60 and above in China, and to provide a reference basis for the scientific and precise prevention and control of FRS in the elderly.Methods:Based on FRS cases surveillance data from information management system of National Technical Platform for Infectious Disease Surveillance, National Science and Technology Major Project of China, the surveillance pathogens included 8 viruses, including influenza virus (IFV), respiratory syncytial virus (RSV), adenovirus (HAdV), parainfluenza virus (HPIV), metapneumovirus (HMPV), coronavirus (HCoV), bocavirus and rhinovirus (HRV); 7 bacterias, namely Streptococcus pneumoniae ( S.pneumoniae), Staphylococcus aureus ( S.aureus), Klebsiella pneumoniae ( K.pneumoniae), Pseudomonas aeruginosa ( P.aeruginosa), Group A Streptococcus ( GAS), Haemophilus influenzae ( H.influenzae) and Legionella pneumophila ( L. pneumophila), in addition to Chlamydia pneumoniae ( C. pneumoniae) and Mycoplasma pneumoniae ( M. pneumoniae). A descriptive epidemiological approach was used to analyze the pathogenic composition and major epidemiological characteristics of FRS cases aged 60 years and older nationwide from 2009 to 2021. Results:The predominant viruses of FRS cases aged≥60 years accounted for 87.93% of the pathogen spectrum in China, including IFV (42.42%), HRV (16.71%), HPIV (11.53%), HCoV (9.52%), and RSV (7.75%), while the pathogen spectrum of the major bacteria accounted for 94.60%, including S. pneumoniae (25.71%), P. aeruginosa (24.97%), K. pneumoniae (22.47%), H. influenzae (12.23%), and S. aureus (9.22%). Influenza viruses have always been at the top of the viral pathogen spectrum, and P. aeruginosa, K. pneumoniae and S. pneumoniae, ranked high in the bacterial pathogen spectrum. Among them, the proportions of HRV, HPIV, RSV, K. pneumoniae, and H. influenzae fluctuated and increased during the 13 years of observation. The positive rate of any pathogen in FRS cases was higher in out patient emergencies (32.83%) than in hospitalized cases (27.26%) ( χ2 =125.89, P<0.001). The positive rate of IFV was higher in cases aged 60-74 years (13.66%). The positive rate of P. aeruginosa and K. pneumoniae were higher in cases aged ≥90 years (10.71%, 9.40%) and in northern regions (8.32%, 7.30%). The positive rate of any pathogen in FRS cases was higher in winter (33.82%) than in other seasons ( χ2=212.03, P<0.001). The positive rate of IFV and HRV were higher in winter (22.87%) and autumn (5.98%) and the positive rate of P.aeruginosa (8.11%) and K.pneumoniae (8.30%) were higher in summer. Conclusions:IFV, HRV, HPIV, S. pneumoniae, P. aeruginosa and K. pneumoniae were respectively the top three pathogens in the viral and bacterial pathogen spectrum of FRS cases aged 60 years and above in China from 2009 to 2021, and the positive rate of these main pathogens showed differences between age groups, seasons, and geographic regions. In the future, the dynamic surveillance of various pathogens in the elderly with respiratory tract infections should be continuously strengthened.

Objective:To identify and summarize the best evidence for pelvic floor muscle exercises (PFME) in preventing pelvic floor dysfunction (PFD) during pregnancy.Methods:A systematic search was conducted in databases including UpToData, Cochrane Library, PubMed, Web of Science, Embase, China National Knowledge Infrastructure, VIP, Wanfang Data, SinoMed, Yiigle, and Joanna Briggs Institute Evidence Based Healthcare Center Database and so on. The search spanned from January 1, 2018, to March 16, 2023. Two researchers independently evaluated the quality of clinical decision-making articles, expert consensus, and systematic reviews, while four researchers appraised the quality of guidelines. Evidence extraction and grading were performed independently by two researchers.Results:A total of nine documents were included: three guidelines, two clinical decision-making articles, one expert consensus, and three systematic reviews. A total of 20 evidence-based recommendations were summarized in six categories: indications and contraindications, assessment, implementation plans, supervision and follow-up, management, and outcome evaluation.Conclusions:PFME during pregnancy is effective in preventing PFD. Healthcare providers should integrate best evidence into clinical practice to develop tailored PFME plans for pregnant women, aiming to prevent PFD.

Objective To investigate the protective effect of Yiqi Yangyin Huazhuo Tongluo Formula(YYHT)against high glucose-induced injury in mouse renal podocytes(MPC5 cells)and the possible mechanism.Methods Adult Wistar rats were treated with 19,38,and 76 g/kg YYHT or saline via gavage for 7 days to prepare YYHT-medicated or blank sera for treatment of MPC5 cells cultured in high glucose(30 mmol/L)prior to transfection with a miR-21a-5p inhibitor or a miR-21a-5p mimic.The changes in miR-21a-5p expressions and the mRNA levels of FoxO1,PINK1,and Parkin in the treated cells were detected with qRT-PCR,and the protein levels of nephrin,podocin,FoxO1,PINK1,and Parkin were detected with Western blotting.Autophagic activity in the cells were evaluated with MDC staining.The effect of miR-21a-5p mimic on FoxO1 transcription and the binding of miR-21a-5p to FoxO1 were examined with luciferase reporter gene assay and radioimmunoprecipitation assay.Results MPC5 cells exposed to high glucose showed significantly increased miR-21a-5p expression,lowered expressions of FoxO1,PINK1,and Parkin1 mRNAs,and reduced levels of FoxO1,PINK1,parkin,nephrin,and podocin proteins and autophagic activity.Treatment of the exposed cells with YYHT-medicated sera and miR-21a-5p inhibitor both significantly enhanced the protein expressions of nephrin and podocin,inhibited the expression of miR-21a-5p,increased the mRNA and protein expressions of FoxO1,PINK1 and Parkin,and upregulated autophagic activity of the cells.Transfection with miR-21a-5p mimic effectively inhibited the transcription of FoxO1 and promoted the binding of miR-21a-5p to FoxO1 in MPC5 cells,and these effects were obviously attenuated by treatment with YYHT-medicated sera.Conclusion YYHT-medicated sera alleviate high glucose-induced injury in MPC5 cells by regulating miR-21a-5p/FoxO1/PINK1-mediated mitochondrial autophagy.

Objective To investigate the age-dependent modulatory effects of treadmill exercise on spatial learning and memory in mice and to elucidate the potential neurobiological mechanisms underlying these effects.Methods Male C57BL/6J mice at three distinct developmental stages were subjected to a controlled treadmill training protocol for a duration of four weeks.Cognitive performance was assessed in terms of spatial learning and memoryusing a series of behavioral tests.To examine exercise-induced neurogenesis,proliferating adult neural stem cells in the hippocampal region were labeled via intraperitoneal administration of BrdU.Meanwhile,physiological parameters,including body and muscle weight,were monitored throughout the experiment.Results The study revealed significant age-specific effects of treadmill training.In one-month-old mice,exercise intervention markedly enhanced spatial learning and memory,along with increased proliferation of hippocampal neural stem cells,but no significant alterations were observed in body or muscle weight.In six-month-old mice,treadmill training selectively improved spatial memory and led to increased muscle weight.Notably,three-month-old mice exhibited no significant exercise-induced changes in cognitive performance,hippocampal neurogenesis,or muscle weight.Conclusion These findings demonstrate that treadmill exercise exerts significant,age-dependent regulatory effects on spatial learning and memory,with the most pronounced and comprehensive improvements observed in one-month-old mice.The cognitive enhancements may be mediated,at least partially,through exercise-induced promotion of hippocampal neurogenesis.This study provides data for elucidation of the mechanistic basis of exercise-mediated cognitive enhancement and contributes to the potential applications of exercise interventions in cognitive optimization and neuroplasticity across different developmental stages.

Cholesterol(CH)plays a crucial role in enhancing the membrane stability of drug delivery systems(DDS).However,its association with conditions such as hyperlipidemia often leads to criticism,overshadowing its influence on the biological effects of formulations.In this study,we reevaluated the delivery effect of CH using widely applied lipid microspheres(LM)as a model DDS.We conducted comprehensive in-vestigations into the impact of CH on the distribution,cell uptake,and protein corona(PC)of LM at sites of cardiovascular inflammatory injury.The results demonstrated that moderate CH promoted the accumulation of LM at inflamed cardiac and vascular sites without exacerbating damage while partially mitigating pathological damage.Then,the slow cellular uptake rate observed for CH@LM contributed to a prolonged duration of drug efficacy.Network pharmacology and molecular docking analyses revealed that CH depended on LM and exerted its biological effects by modulating peroxisome proliferator-activated receptor gamma(PPAR-γ)expression in vascular endothelial cells and estrogen receptor alpha(ERα)protein levels in myocardial cells,thereby enhancing LM uptake at cardiovascular inflam-mation sites.Proteomics analysis unveiled a serum adsorption pattern for CH@LM under inflammatory conditions showing significant adsorption with CH metabolism-related apolipoprotein family members such as apolipoprotein A-V(Apoa5);this may be a major contributing factor to their prolonged circu-lation in vivo and explains why CH enhances the distribution of LM at cardiovascular inflammatory injury sites.It should be noted that changes in cell types and physiological environments can also influence the biological behavior of formulations.The findings enhance the conceptualization of CH and LM delivery,providing novel strategies for investigating prescription factors' bioactivity.
