ObjectiveTo investigate the detection status of scoliosis and its influencing factors among primary and secondary school students in Jiangqiao Town in Jiading District of Shanghai, thereby providing evidence for the prevention and management of scoliosis in children and adolescents. MethodsA stratified cluster random sampling was conducted in March 2025. Three primary schools and two secondary schools in Jiangqiao Town were randomly selected; within each school, 3‒4 entire classes were randomly chosen. Screening was performed in accordance with the criteria specified in GB/T 16133‒2014 Screening for Abnormal Spinal Curvature in Children and Adolescents, and a self-designed structured questionnaire was administered to conduct face-to-face surveys (Cronbach’s α=0.730). ResultsA total of 772 valid questionnaires were collected on-site, representing a 100% response rate. The sample consisted of 413 males (53.50%) and 359 females (46.50%), including 385 primary school students (49.87%) and 387 secondary school students (50.13%). The detection rate of scoliosis in primary and secondary school students was 12.05%. The detection rates were 8.72% for males and 15.88% for females, with the female rate being significantly higher than the male rate (χ²=9.29, P=0.002). For primary and secondary school students, the detection rates were 6.75% and 17.31%, respectively, with the secondary school student rate being significantly higher (χ²=20.31, P<0.001). The results of univariate analysis revealed that students with sufficient sleep and standard sitting postures during reading/writing had a significantly lower scoliosis detection rate compared to those with insufficient sleep and non-standard sitting postures (χ²=5.90, P=0.015 and χ²=5.09, P=0.024). Multivariate logistic regression analyses revealed that the detection rate of scoliosis was significantly higher in females than in males (OR=1.846， 95%CI: 1.156‒2.984), and significantly higher in secondary school students than in primary school students (OR=2.722， 95%CI: 1.656‒4.472). ConclusionThe scoliosis detection rate among primary and secondary school students in Jiangqiao Town in Jiading District is relatively high. Females and secondary school students are key populations requiring targeted prevention and control efforts. It is imperative to strengthen health education on scoliosis, promote early screening and diagnosis, and implement timely targeted interventions.

Objectives:Recently,domestical developed left ventricular assist devices(LVAD)have been frequently introduced into clinical practice.This study aims to report the anesthesia protocol and perioperative outcomes in Chinese patients receiving LVAD implantation surgery.Methods:This retrospective analysis included patients who underwent LVAD implantation at our center from June 2017 to November 2024.During and after separation from cardiopulmonary bypass,we optimized right heart function through careful adjustments in heart rate,rhythm,preload,myocardial contractility,and afterload.Vasoactive agents were administered as needed,and mechanical ventilation parameters were optimized.We implemented blood conservation strategies and established strict transfusion criteria to minimize allogenic blood transfusions.Results:A total of 100 patients were included in the analysis,with 54.0%classified as Interagency Registry for Mechanically Assisted Circulatory Support(INTERMACS)I or II.Before leaving the operating room,the mean arterial pressure(MAP),mean pulmonary arterial pressure(mPAP),central venous pressure(CVP),lactic acid levels,and urinary output after cardiopulmonary bypass were recorded as(74±7)mmHg,(25±7)mmHg,(7±3)mmHg,(2.3±1.9)mmol/L,and(8.2±5.4)ml/(kg·h),respectively.The transfusion rates for red blood cells and fresh frozen plasma were 20.0%and 28.0%.The in-hospital mortality rate was 3.0%,with a low incidence of severe complications including right heart failure(12%).Left ventricular ejection fraction increased from(23.7±4.8)%preoperatively to(25.3±10.5)%prior to discharge.Conclusions:Patients who received LVAD at our center exhibited low rates of postoperative mortality and complications and significant improvement in left heart function before discharge.

Cultivating intern's doctor-patient communication skills is crucial for fostering a patient-centered approach in medical practice.This process helps to overcome information gaps,cognitive and ideological barriers,and trust between doctors and patients,thereby laying a strong foundation for the interns' future careers.Clinical internships encompass several stages where doctor-patient communication is emphasized:during the preparation phase,while collecting medical history,throughout the treatment process,and before and after surgical procedures.Key strategies for developing these skills include clearly defining es-sential communication components,engaging in diverse communication practice activities,leveraging the guidance of instructors,and enhancing assessment,and evaluation mechanisms for communication skills.

In the era of deep technologization with the flourishing development of newquality productive forces， China’s medical science and technology innovation has transitioned from “following” to “leading”， and the ethical governance environment of medical science and technology has undergone profound changes. However， the traditional ethical governance system of medical science and technology faces several issues， such as outdated ethical governance concepts， inadequate ethical norms， excessive hidden ethical risks， and numerous loopholes in governance systems， which fail to effectively respond to the diverse and complex ethical risk challenges. To this end， it is essential to promote the transformation of ethical governance thinking in medical science and technology based on the reality of newquality productivity forces and deep technologization， as well as to shift unilateral， extensive， and single governance into comprehensive， precise， and early-warning governance. Additionally， it is necessary to cultivate an ethical governance concept that prioritizes ethics and prevention， establish a diverse and collaborative ethical governance model， set up a prevention mechanism focused on major ethical risks， as well as enhance the systems of ethical communication， review， and feedback in medical science and technology.

Objectives:To evaluate the tricuspid valve(TV)geometric remodeling in patients with idiopathic pulmonary arterial hypertension(IPAH)by three-dimensional transthoracic echocardiography. Methods:Two-dimensional and three-dimensional transthoracic echocardiography were performed in 30 IPAH patients and 15 healthy controls,and the geometry parameters of TV were obtained by four-dimensional auto tricuspid valve quantitative(4D Auto-TVQ)in the right ventricular-focused apical view.Pulmonary arterial hypertension was determined by right heart catheterization within 48 hours of echocardiography. Results:The 4-chamber diameter,tricuspid annular(TA)perimeter,TA area,maximal tenting height,coaptation point height and tenting volume were larger in IPAH patients than those in healthy controls(all P＜0.05),2-chamber diameter was similar between two groups.In IPAH group,maximal tenting height and coaptation point height were moderately correlated with right ventricular end-diastolic volume(r=0.710,r=0.515,both P＜0.05),while TA perimeter,4-chamber diameter and TA area were moderately correlated with right atrial end-systolic volume(r=0.712,r=0.558,r=0.545,all P＜0.05). Conclusions:IPAH patients have larger maximal tenting height,coaptation point height and tenting volume,TA enlargement is mainly visible in 4-chamber diameter.TV tenting height is associated with right ventricular volume,but TA size is associated with right atrial volume in IPAH patients.

Objective:To assess the long-term outcome of sequential radical surgery after immune combined with targeted therapy for patients with initially unresectable hepatocellular carcinoma (HCC).Methods:Clinical data of 100 patients with initially unresectable HCC undergoing sequential radical surgery after immune combined with targeted therapy at the Faculty of Hepato-Pancreato-Biliary Surgery of Chinese PLA General Hospital from December 2018 to August 2023 were prospectively collected, including 87 males and 13 females, with a median age of 55 (24-73) years. The pre-treatment tumor staging was determined using the China liver cancer staging (CNLC). The efficacy of immune combined with targeted therapy was accessed using the modified response evaluation criteria in solid tumor (mRECIST). The cycles of immune combined with targeted therapy were analyzed. The tumor residual of resected tissue was analyzed through a standard pathological protocol. The prognosis was analyzed using the Kaplan-Meier method.Results:Upon initial diagnosis, there were 46 cases (46.0%) staged CNLC-Ⅲa and 40 (40.0%) staged CNLC-Ⅲb. There were also 14 cases (14.0%) staged CNLC-Ⅰb, Ⅱa, and Ⅱb who underwent immune combined with targeted therapy due to rupture of tumor or insufficient liver remnant. All patients received a median of 5 (3-28) cycles of immune combined with targeted therapy and underwent radical surgery after successful conversion. According to mRECIST, 14 (14.0%) were determined as complete remission, 63 (63.0%) as partial remission, 18 (18.0%) as stable disease, and 5 (5.0%) as disease progression. Of 24 (24.0%) were defined as pathologically complete remission by postoperative pathology. Furthermore, pathological tumor residue was less than 10% in 61 (61.0%) cases and less than 50% in 82 (82.0%) cases. The 1, 3, and 5 year-overall survival rates of patients were 98.0%, 83.1%, and 74.5%, respectively. The 1, 2 and 3 year-recurrence-free survival rates were 67.5%, 54.8%, and 49.6%, respectively.Conclusion:Sequential radical surgery after immune combined with targeted therapy benefits the long-term survival of patients with initially unresectable HCC.

Extracorporeal membrane oxygenation (ECMO) is a critical life support technique for patients with severe cardiopulmonary failure. Establishing a stable ECMO animal model is essential to further investigate the effects of ECMO on the body and provide assistance for optimizing ECMO management strategies and preventing complications in clinical practice. In recent years, rats have been widely used to establish ECMO models due to their low cost and good reproducibility. Therefore, this article provided a comprehensive review of literature on the ECMO rat model, including equipment and experimental management strategies. It offers a theoretical foundation for the development of a stable and mature ECMO rat model in the future.
