Objective To explore the causal relationship between immune cells and heart failure (HF), and the mediating role of serum metabolites, in order to identify potential biomarkers and therapeutic targets. Methods We employed a two-sample Mendelian randomization (MR) analysis method based on genome-wide association study (GWAS) data, analyzing the direct and indirect effects of 731 types of immune cells and 1 400 metabolites on HF. We selected valid instrumental variables and conducted statistical analyses using R software. The primary analysis was performed using the inverse variance weighted method, supplemented by MR-Egger analysis and weighted median method. The stability of the results was assessed through tests such as Cochran’s Q test. Results Our research found a negative causal relationship between PD-L1 on CD14−CD16+ and HF. Sensitivity analysis supported this result. The reverse MR analysis did not find an effect of HF on PD-L1 on CD14−CD16+, indicating that PD-L1 on CD14−CD16+ might play a unidirectional role in reducing the risk of HF. Further mediation MR analysis showed that PD-L1 on CD14−CD16+ might influence the risk of HF onset by regulating the levels of sphingomyelin (d17:1/14:0, d16:1/15:0), with a mediation effect ratio of 6.7%. Conclusion PD-L1 on CD14−CD16+ may reduce the risk of HF by elevating the levels of sphingomyelin (d17:1/14:0, d16:1/15:0), which provides a new perspective for understanding the pathogenesis of HF.

Objective To explore the mediating role of intolerance of uncertainty(IU)and moderating role of the negative emotion differentiation in the influence of perceived stress on anxiety among college students from a cognitive perspective.Methods A total of 271 participants were surveyed using the perceived stress scale,intolerance of uncertainty scale,depression anxiety and stress scale(Chinese version),and the test on negative emotional differentiation.SPSS 22.0 was used to perform descriptive statistics and correlation analyses and to test the moderated mediation model.Results Perceived stress affected anxiety and IU played a mediating role-perceived stress could affect anxiety through influencing IU.At the same time,the influence of IU on anxiety could be adjusted through the negative emotion differentiation.The higher the degree of negative emotion differentiation,the lower the degree of anxiety increase(β=0.17,t=5.70,P＜0.01).Conclusion It may be effective to develop training programs to reduce anxiety by regulating perceived stress,increasing acceptance of uncertainty,and improving the negative emotion differentiation,which can help individuals reduce anxiety by perceiving and adjusting anxiety-related emotional or cognitive factors in a timely manner.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Objective:To investigate the effects of preoperative enteral nutrition on nutrition-related complications and gastrointestinal function in esophageal cancer patients by administering EN before surgery.Methods:A total of 215 patients who underwent thoracoscopic esophagectomy at Nanjing Hospital of Traditional Chinese Medicine between January 2018 and December 2020 were retrospectively analyzed in this study. Among them, 145 patients received enteral nutrition preconditioning, while 70 patients received traditional nutritional support. The nutritional risk was assessed according to the Nutritional Risk Screening 2002 (NRS2002), and the patients were categorized into non-nutritional risk group (NRS2002<3) and nutritional risk group (NRS2002≥3). Patients in the traditional nutritional support group with NRS2002<3 were provided with a regular diet three days prior to surgery, whereas those with NRS2002≥3 received intravenous fat emulsion amino acid glucose for nutritional support. In the enteral nutrition preconditioning group, patients with NRS2002<3 received 500 mL/d of enteral nutrition suspension orally in addition to their regular diet for 3 days preoperatively; those with NRS2002≥3 received received 1000 mL/d of enteral nutrition suspension orally or via gastric tube. Postoperative hospital stay, time to gas passage and defecation, hospital expenses, gastrointestinal dysfunction incidence including diarrhea, abdominal distension and constipation, postoperative routine blood indicators, anastomotic fistula occurrence as well as infectious complications such as pneumonia and wound infection were compared between groups. Measurement data with normal distribution was expressed as Mean±SD, independent sample t-test was used on comparison between groups. Counting data was expressed as case(%), χ2 test was used on comparison between groups, P<0.05 was considered as statistically significant. Results:The incidence of anastomotic leakage and infectious complications in the enteral nutrition pre-adaptation group was 4.83% (7/145) and 4.83% (7/145), respectively, showing no statistically significant differences compared to the traditional nutrition support group [2.86% (2/70) and 8.57% (6/70)] ( χ2=0.46 and 1.16, P=0.499 and 0.280, respectively). The incidences of gastrointestinal dysfunction and overall complications in the enteral nutrition pre-adaptation group were 5.52% (8/145) and 13.10% (19/145), respectively, which were significantly lower than those in the traditional nutrition support group [37.14% (26/70) and 45.71% (32/70)] ( χ2=35.47 and 27.75, both P<0.001). Postoperative outcomes in the enteral nutrition pre-adaptation group, including hospital stay (14.05±3.75 days), time to first flatus (25.75±5.03 hours), time to first defecation (49.25±5.98 hours), and hospitalization costs (85,200±13,500 CNY), were significantly better than those in the traditional nutrition support group [(16.46±4.79 days, 31.53±6.55 hours, 63.45±11.43 hours, and 93,500±20,100 CNY)] ( t=3.70, 6.52, 9.77, and 3.17, all P<0.001). No significant differences were observed in routine postoperative blood tests between the two groups (all P>0.05). Stratified analysis revealed that among patients with preoperative nutritional risk, the enteral nutrition pre-adaptation group demonstrated superior outcomes in hospitalization costs (82,300±11,000 CNY), time to first flatus (26.17±5.69 hours), time to first defecation (50.31±5.59 hours), overall complication rate (15.79%), and gastrointestinal dysfunction rate (7.89%) compared to the traditional nutrition support group [100,800±28,800 CNY, 31.42±6.29 hours, 60.80±9.89 hours, 54.55%, and 40.91%] ( t=2.89, P=0.008; t=3.32, P=0.002; t=4.57, P<0.001; χ2=9.97, P=0.002; χ2=9.49, P=0.002). Similarly, among patients without preoperative nutritional risk, the enteral nutrition pre-adaptation group showed better results in hospital stay (13.69±3.83 days), time to first flatus (25.60±4.80 hours), time to first defecation (48.87±6.10 hours), overall complication rate (12.15%), and gastrointestinal dysfunction rate (4.67%) compared to the traditional nutrition support group [16.60±4.36 days, 31.58±6.73 hours, 64.67±11.98 hours, 41.67%, and 35.42%] ( t=4.19, t=5.56, t=8.65, χ2=17.23, χ2=25.72, all P<0.001). Conclusion:Enteral nutrition pre-adaptation positively impacts post-esophagectomy nutrition-related complications and gastrointestinal dysfunction.nutrtional support before surgery can't be neglected.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective:To explore the efficacy and its related factors of rituximab (RTX) in the treatment of children with frequently relapsing nephrotic syndrome/steroid-dependent nephrotic syndrome (FRNS/SDNS).Methods:It was a single-center retrospective study. The clinical data of FRNS/SDNS children first treated with RTX in the First Affiliated Hospital of Sun Yat-sen University from November 1, 2016 to September 1, 2023 were collected. The number of relapse within 1 year before and after RTX treatment, the time to first relapse after RTX treatment, and the time to B-cell reconstitution were analyzed. At the first treatment, a single dose of RTX was given at 375 mg/m 2, with a maximum dose of 500 mg, once a week, for 1 to 4 doses. The count of CD19 + lymphocytes in the peripheral blood of the children was continuously monitored. If B-cell reconstruction was performed, the decision on whether to proceed to the next course of RTX treatment was made based on clinical manifestations. Kaplan-Meier method was used to analyze relapse-free survival rate after receiving RTX. Cox proportional hazards regression model was used to analyze the related factors of relapse after RTX treatment. Results:A total of 98 FRNS/SDNS children receiving RTX treatment were enrolled, including 75 males (76.5%). The age at onset was 4.0 (1.9, 7.1) years and age of receiving RTX was 11.3 (8.5, 13.5) years. There were 90 children (91.8%) achieving complete remission, while 8 patients (8.2%) did not respond to RTX treatment, and 3 patients (3.1%) progressed to end-stage kidney disease after receiving RTX. The relapse-free survival rates at 6 months and 1 year after RTX treatment were 83.3% (75/90) and 57.9% (22/38), respectively. The frequency of relapse 1 year after RTX treatment decreased compared to 1 year before RTX treatment ( Z=-7.398, P<0.001). Compared with children without relapse during the period of B-cell depletion, relapsed children had a higher number of relapse within one year after RTX treatment ( Z=5.246, P<0.001). The time to first relapse after RTX treatment was 8.3 (4.6, 13.9) months in 51 relapse patients. Compared with children receiving 1 dose of RTX in the first course, those receiving 2 or more doses had a longer time to the first relapse ( Z=2.983, P=0.003). There was no statistically significant difference in time to the first relapse between children who received mycophenolate mofetil therapy after RTX treatment and those who didn't ( P>0.05). The reconstruction time of B cells after the first course of RTX was 6.9 (5.3, 9.0) months. Compared to children receiving one dose of RTX in the first course, those receiving two or more doses had a longer B-cell reconstitution time ( Z=2.739, P=0.006). There was no statistically significant difference in B-cell reconstitution time between children who received mycophenolate mofetil therapy after RTX treatment and those who didn't ( P>0.05). Univariate Cox regression analysis showed that recurrence after calcineurin inhibitor (CNI) treatment before RTX treatment and the number of recurrence in one year before RTX treatment were correlated factors of recurrence after RTX treatment (both P<0.05). Multivariate Cox regression analysis showed that recurrence after CNI treatment before RTX treatment was an independent correlated factor of relapse after RTX therapy ( HR=3.496, 95% CI 1.245-9.818, P=0.018). Infusion reactions occurred in 10 patients (10.2%) and infections were observed in 24 patients (24.5%) during B cell depletion. No serious adverse events occurred. Conclusions:RTX is well tolerated and effective in treating FRNS/SDNS. Recurrence after CNI treatment before RTX treatment may be an independent related factor of relapse after RTX treatment.

Retrograde intrarenal surgery（RIRS）has become a first-line therapeutic option for upper urinary tract stones ≤2 cm. Although conventional ureteral access sheaths enable smooth ureteroscope insertion and reduce intrarenal pressure，but the stone-free rate（SFR）remains limited. Recently，a novel flexible and navigable suction ureteral access sheath（FANS）has improved the stone clearance efficiency，therapeutic effect，and safety of RIRS. The advent of FANS is progressively reshaping the role of RIRS within urological endoscopic surgery. This review aims to summarize the current research on FANS in the management of urolithiasis and discuss potential directions for its future development.

We report a 30-year-old woman who presented with intermittent gross hematuria and left flank pain，and CT revealed a left staghorn stones. The initial percutaneous nephrolithotomy（PCNL）left a 6 mm fragment，and both stone and urine cultures yielded extended-spectrum β-lactamase（ESBL）-producing Escherichia coli. Seven months later，the stone increased to 6 cm and urine culture revealed Proteus mirabilis. Endoscopic combined intrarenal surgery（ECIRS）achieved complete clearance. At 6-month follow-up，the patient remained asymptomatic，culture-negative，and stone-free. This case highlights that small residual fragments after PCNL may rapidly enlarge with secondary urease-producing infection，underscoring the need for early re-intervention and standard follow-up.
