Clinical data of a patient with alveolar soft part sarcoma (ASPS) treated at Zhongshan Hospital, Fudan University were retrospectively analyzed. The patient was initially diagnosed with abdominal ASPS with multiple lung metastases. After 6 weeks of treatment with nivolumab and ipilimumab, the patient achieved stable disease (SD). In the 7th week, the treatment was changed to a combination of nivolumab (30 mg, d1, q3w), anlotinib (8 mg, d1-14, q3w) and ipilimumab (50 mg, d1, q6w). The patient remained SD at the 12th week. The patient then underwent iliac artery embolization and intensity-modulated radiation therapy for the lesion in the psoas major muscle, while continuing the combination treatment. By the 24th week, the evaluation showed partial remission (PR) of both primary tumor and lung metastases. The patient experienced mild adverse reactions during treatment.

This article systematically analyzes the historical evolution of the name， origin， quality evaluation， harvesting， processing and other aspects of Picrorhizae Rhizoma by referring to the medical books， prescription books， and other documents of the past dynasties， combined with relevant modern research materials， in order to provide a basis for the development and utilization of famous classical formulas containing this medicinal herb. The research results indicate that Picrorhizae Rhizoma was first recorded in New Revised Materia Medica from the Tang dynasty. Throughout history， Huhuanglian has been used as its official name， and there are also aliases such as Gehu Luze， Jiahuanglian and Hulian. The main source of past dynasties is the the rhizomes of Picrorhiza kurrooa and P. scrophulariiflora. In ancient times， Picrorhizae Rhizoma was mainly imported by foreign traders via Guangzhou and other regions， and also produced in China， mainly in Xizang. In ancient times， it was harvested and dried in early August of the lunar calendar， while in modern times， it is mostly harvested from July to September， with the best quality being those with thick and crispy rhizomes without impurities， and bitter taste. Throughout history， Picrorhizae Rhizoma was collected， washed， sliced， and dried before being used as a raw material for medicine， it has a bitter and cold taste， mainly used to treat bone steaming， hot flashes， infantile chancre fever， and dysentery. There is no significant difference in taste and efficacy between ancient and modern times. Based on the research results， it is recommended that the rhizomes of P. scrophulariiflora in the 2020 edition of Chinese Pharmacopoeia， or the rhizomes of P. kurrooa， can be used in famous classical formulas containing this medicinal herb， which can be processed according to the processing requirements marked by the original formula. For those without clear processing requirements， the dried raw products are used as medicine.

OBJECTIVE To evaluate the quality of Mongolian medicine Sendeng-4 based on qualitative and quantitative analysis combined with chemical pattern recognition， in order to provide the reference for its quality control. METHODS The chemical components in Sendeng-4 were analyzed qualitatively by HPLC-Q-Exactive-MS.

Cluster analysis （CA）， principal component analysis （PCA）， and orthogonal partial least squares discriminant analysis were conducted and variable importance projection （VIP） value greater than 1 was used as the index to screen the differential components. RESULTS A total of 73 chemical components were identified in Sendeng-4， including 20 flavonoids， 16 tannins， 14 organic acids， etc. According to the quantitative analysis， the results exhibited that the average contentsthe of above 16 components in 15 batches of Sendeng-4 were 3.683-7.730， 2.391-6.952， 2 275.538-4 377.491， 2 699.188-3 537.924， 858.266-1 377.393， 3.366-11.003， 140.624-315.683，414.629-978.334， 285.501-1 510.457， 27.799-48.325， 3 625.415-6 309.563， 0.506-0.656， 442.337-649.283， 47.093-59.736， 12.942-15.822， 127.738-326.649 μg/g， respectively. According to the results of CA and PCA， 15 batches of samples could be clustered into two categories: S1-S3， S5-S6， S9-S10 and S13 were clustered into one category； S4， S7-S8， S11-S12， S14-S15 were clustered into one category. VIP values of geniposide， epicatechin， deacetylasperulosidic acid methyl ester and genipin-1-O- β-D-gentiobioside were all greater than 1. CONCLUSIONS HPLC-Q-Exactive-MS and HPLC-MS/MS techniques are employed for the qualitative and quantitative analysis of Sendeng-4. Through chemical pattern recognition analysis， four differential components are identified: geniposide， epicatechin， deacetylasperulosidic acid methyl ester， and genipin-1-O-β-D-gentiobioside.

Objective To understand the current situation of healthcare-associated infection(HAI)in China,pro-vide data support and decision-making basis for formulating scientific and effective strategies for HAI prevention and control.Methods A nationwide cross-sectional survey on HAI was conducted among various types and levels of medical institutions in China according to a unified protocol of bedside surveys and case investigations.Results In 2024,a total of 5 736 medical institutions and 2 751 765 patients were surveyed.Among them,34 889 HAI cases were identified,with a prevalence rate of 1.27％.The number of HAI episodes was 38 032,and case prevalence rate was 1.38％.The prevalence rate of HAI in medical institutions in different regions of China ranged from 0.66％to 2.35％.Among medical institutions of different scales,those with a bed capacity of ≥900 had the high-est incidence of HAI,reaching 1.65％.The most common infection site was the lower respiratory tract(44.66％),followed by the urinary tract(12.94％),surgical site(9.32％),upper respiratory tract(7.02％),and bloodstream infection(5.78％).The top 3 departments with the highest HAI rates were the general intensive care unit(10.02％),department of neurosurgery(5.51％),and department(group)of hematology(5.34％).A total of 23 238 strains of HAI pathogens were detected,with 10 714 strains(46.10％)from lower respiratory tract speci-mens.The top 5 detected strains were Klebsiella pneumoniae(14.76％),Pseudomonas aeruginosa(13.33％),Escherichia coli(12.79％),Acinetobacter baumannii(9.23％),and Staphylococcus aureus(7.88％).231 944 pa-tients underwent class Ⅰ incision surgery were monitored,with 1 647 cases experienced surgical site infection,and the prevalence rate of surgical site infection was 0.71％.The number of patients who should undergo pathogen de-tection(patients receiving therapeutic and therapeutic combined prophylactic antimicrobial agents)was 715 179,while the actual number was 480 492,with a pathogen detection rate of 67.18％.425 225 patients received patho-genic detection before treatment,with a detection rate of 59.46％.Conclusion The overall HAI prevalence in Chi-na is lower,showing disparities among medical institutions of different regions and scales.Therefore,precise imple-mentation of measures is necessary for HAI prevention and control,with a focus on high-risk institutions and high-risk departments,key areas,and critical procedures.All levels of medical institutions should continuously reduce the incidence of HAI by strengthening monitoring,standardizing the use of antimicrobial agents,and reinforcing basic HAI prevention and control measures.

Objective To explore the value of three-dimensional automated right ventricular quantification(3D Auto RV)for predicting right ventricular function dysfunction in patients with severe aortic stenosis(AS).Methods Eighty severe AS patients were retrospectively enrolled.Based on right ventricular ejection fraction(RVEF)obtained with 3D Auto RV,the patients were classified into right ventricular compensation group(RVEF≥45%,compensation group,n=56)and right ventricular function decompensation(RVEF＜45%,decompensation group,n=24)group.Ultrasonic parameters related to right ventricular structure and function were compared between groups.Univariable analysis and multivariable logistic regression were performed to observe ultrasound parameters related to right ventricular function,so as to screen out the independent predictors of right ventricular functional decompensation(dysfunction)in patients with severe AS.Results Compared with those in compensation group,right ventricular end diastolic volume and right ventricular end systolic volume of decompensation group increased,while right ventricular fractional area change,tricuspid annular plane systolic excursion,right ventricular free wall longitudinal strain(RVFWLS),septal longitudinal strain(SLS),right ventricular stroke volume and RVEF all decreased(all P＜0.05).Valvulo-arterial impedance(OR=2.337),left ventricular ejection fraction(OR=0.751)and RVFWLS/pulmonary artery systolic pressure(right ventricle-pulmonary artery coupling)(OR=0.653)were all independent predictors of right ventricular dysfunction in patients with severe AS(all P＜0.05).Conclusion 3D Auto RV could be used to effectively predict right ventricular dysfunction in patients with severe AS.

Objectives:This study aimed to investigate the impact of quantitative flow ratio(QFR)-guided revascularization on outcome of elderly patients with coronary artery disease(CAD)undergoing valve surgery.Methods:We retrospectively analyzed 750 consecutive patients with angiographically confirmed CAD(≥50%stenosis)who underwent valve surgery at Zhongshan Hospital,Fudan University,between January 2016 and December 2021.According to the patients'ages,they were divided into the younger group(age<70 years old,n=532)and the elderly group(age≥70 years old,n=218).Revascularization strategies were evaluated using anatomical(angiography-based)and functional(QFR-based)criteria.Anatomical complete revascularization(CR)was defined as bypass grafting for all lesions with≥70%diameter stenosis in major coronary arteries or≥50%stenosis in the left main coronary artery.Functional CR referred bypass grafting for all lesions with QFR≤0.80.Incomplete revascularization(ICR)was defined as failure to meet CR criteria.According to the anatomical and functional definitions,the younger group and the elderly group were further divided into the incomplete revascularization subgroup and the complete revascularization subgroup respectively.Major adverse cardiovascular events(MACE),including death,myocardial infarction,repeat revascularization,and stroke,were assessed as the composite endpoint.Results:Over a follow-up of(3.7±1.8)years,the overall MACE rate was 13.3%.The younger group exhibited significantly lower MACE rates than the elderly group(10.7%vs.19.7%,P=0.001).In the younger group,anatomical ICR did not increase MACE risk(HR=1.46,95%CI:0.81-2.62,P=0.164),whereas functional ICR significantly increased MACE risk(HR=2.27,95%CI:1.24-4.15,P=0.001).In the elderly group,neither anatomical ICR(HR=1.22,95%CI:0.62-2.41,P=0.540)nor functional ICR(HR=1.52,95%CI:0.78-2.96,P=0.172)was associated with increased MACE risk.Conclusions:In patients undergoing valve surgery with CAD,functional ICR correlated with adverse outcomes in the younger group,whereas neither anatomical nor functional ICR significantly affected prognosis in elderly patients.These findings suggest that a moderately conservative revascularization strategy may be more appropriate for elderly populations.

Temporomandibular disorders (TMD), a common condition in oral and maxillofacial surgery, significantly impairs patients' quality of life. Early prediction and appropriate treatment of TMD are therefore critically important. Research on TMD prediction models has evolved from traditional statistical methods to machine learning and subsequently to deep learning, each offering unique advantages and limitations. Traditional statistical methods can effectively identify independent risk factors influencing treatment outcomes but generally rely on substantial prior knowledge and assumptions. Machine learning techniques can process large-scale, high-dimensional data and autonomously learning patterns and regularities within datasets. However, they exhibit strong dependence on data quality and limited model generalization capabilities. Deep learning approaches excel at automatically extracting temporal patterns and trends from time-series data while effectively capturing complex nonlinear relationships, yet they require extensive training datasets and suffer from interpretability challenges due to their inherent black-box testing. This review comprehensively evaluates the implementation and performance of these computational approaches in TMD prediction, critically analyzes their respective strengths and constraints, and discusses promising future research directions.

Objective:To evaluate the clinical process of fragment reattachment in crown-root fractures (CRF) of teeth that the fracture occurred between sub-gingival and supra-alveolar ridge (sub-gingival & supra-alveolar ridge) in the esthetic zone, and to analyze the feasibility of this minimally invasive technique for sub-gingival & supra-alveolar ridge CRF involving anterior teeth.Methods:Fourteen sub-gingival & supra-alveolar ridge CRF involving anterior teeth in 12 patients received fragment reattachment in the Department of Prosthodontics, School of Stomatology, the Fourth Military Medical University from January 2016 to August 2024. The success rate of the fractured teeth 3 years after reattachment and the complications during the follow-up period were retrospectively analyzed. The 3-year success rate and complications during follow-up were evaluated to assess the clinical efficacy of this technique.Results:The 14 treated teeth were followed for an average of (36.0±33.7) months (range: 4-99 months). Complications occurred in 2 teeth: one was extracted due to debonding and replaced with a removable partial denture, while the other developed a palatal sinus post-reattachment, which healed after local saline irrigation and medication (followed for 12 months without recurrence). The remaining 12 teeth exhibited no complications, resulting in a success rate of 13/14.Conclusions:Fragment reattachment is a minimally invasive, rapid, and cost-effective treatment option for sub-gingival & supra-alveolar ridge CRF in the anterior esthetic zone. With strict case selection, it delivers favorable outcomes and extends the clinical lifespan of affected teeth.

Objective:To analyze the relationship between 24-hour urinary calcium (24 h UCa) level and the risk of end-stage kidney disease (ESKD), cardiovascular disease (CVD), and all-cause mortality.Methods:In the Chinese Cohort Study of Chronic Kidney Disease, we examined 3 375 patients aged 18-74 years with CKD stages 1-4. Kaplan-Meier survival and Cox proportional hazard regression models were used to test a time-to-event association between levels of 24 h UCa and incidence of ESKD, CVD, and all-cause mortality.Results:During a follow-up of 4.17 (3.37, 5.20) years, 179, 145, 104 and 38 ESKD events occurred in <0.60, 0.60-, 1.20-, ≥2.32 mmol 24 h UCa groups. Higher levels of 24 h UCa (1.20-,≥2.32 mmol) were independently associated with a lower incidence of ESKD events in patients with CKD, with HR (95% CI) of 0.71 (0.54-0.93) and 0.43 (0.29-0.64), respectively. No significant associations with CVD and all-cause mortality endpoints were detected. Conclusion:Among patients with CKD, levels of 24 h UCa displayed an association with the risk of ESKD among patients with CKD stages 1-4.
