Objective To investigate the efficacy of early, short-term, low-dose corticosteroid administration for the prevention and treatment of early acute lung injury (EALI) in patients undergoing thoracoscopic lobectomy. Methods A retrospective analysis was conducted on the clinical data of patients who underwent thoracoscopic lobectomy at the Department of Thoracic and Cardiovascular Surgery, Taihe Hospital, Hubei University of Medicine, from January 2019 to January 2022. Patients were divided into an early steroid therapy group and an observation group based on whether they received corticosteroids in the early postoperative period. In the early steroid therapy group, in addition to standard postoperative care, patients received a low-dose intravenous push of methylprednisolone (80-120 mg/d) for 3 consecutive days. In the observation group, patients received standard postoperative care without intravenous corticosteroids for the first 3 days. Chest plain CT scans were performed on postoperative day (POD) 1 and POD 3 or 4 to evaluate lung injury. CT scores and the incidence of postoperative EALI were recorded. Results A total of 521 patients were included (268 males, 253 females; age range: 11-80 years). There were 318 patients in the observation group and 203 in the early steroid therapy group. On POD 1, the incidence of EALI was 16.0% in the observation group and 13.8% in the early steroid therapy group, with no statistical difference (P=0.486). Correspondingly, there was no statistical difference in chest CT scores among EALI-positive patients between the two groups (P=0.927). On POD 3-4, the incidence of EALI was significantly lower in the early steroid therapy group (22.7%) compared to the observation group (33.6%) (P=0.007). Although chest CT scores among EALI-positive patients were lower in the early steroid therapy group, the difference was not statistically significant (P=0.377). The overall incidence of EALI within the first 4 postoperative days was significantly lower in the early steroid therapy group (26.1%) than in the observation group (37.4%) (P=0.007). Radiological progression (defined as new-onset EALI or progression of existing EALI) occurred in 14.8% of the early steroid therapy group, significantly lower than the 28.9% in the observation group (P<0.001). The early steroid therapy group had a shorter postoperative length of stay (P<0.001), while there was no statistical difference in the incidence of poor wound healing between the groups (P=0.762). Conclusion Early postoperative corticosteroid use effectively reduces the incidence of EALI on POD 3-4, lowers the risk of radiological progression, and decreases the overall incidence of postoperative EALI. This is achieved without prolonging the length of stay or increasing the risk of poor wound healing. Therefore, early administration of low-dose corticosteroids is beneficial in suppressing the occurrence and progression of EALI. Its early use is recommended for patients at high risk for postoperative EALI.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Compulsory medical treatment is considered a necessary means to maintain public health. It faces many ethical dilemmas during its implementation， primarily concerning issues of autonomy. The discussion of autonomy issues is grounded in the concept， which faces difficulties in explanation and challenges in power structures. In addition to conceptual issues， autonomy also encounters various controversies in practice， including rational suicide， interpersonal relationships， bioethical principles， and other aspects. Faced with challenges， Bjorn Hofmann’s polyvalent concept clarifies the concept of autonomy， and the relational ethical approach provides innovative solutions to the practical issues of autonomy.

Background::Cardiovascular disease (CVD) has emerged as the leading cause of death from prostate cancer (PCa) in recent decades, bringing a great disease burden worldwide. Men with preexisting CVD have an increased risk for major adverse cardiovascular events when treated with androgen deprivation therapy (ADT). The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China.Methods::Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling. CVD was defined as myocardial infarction, arrhythmia, heart failure, stroke, ischemic heart disease, and others. CVD risk was estimated by calculating Framingham risk scores (FRS). Patients were accordingly divided into low-, medium-, and high-risk groups. χ2 or Fisher’s exact test was used for comparison of categorical variables. Results::A total of 4253 patients were enrolled in the present study. A total of 27.0% (1147/4253) of patients had comorbid PCa and CVD, and 7.2% (307/4253) had two or more CVDs. The enrolled population was distributed in six regions of China, and approximately 71.0% (3019/4253) of patients lived in urban areas. With imaging and pathological evaluation, most PCa patients were diagnosed at an advanced stage, with 20.5% (871/4253) locally progressing and 20.5% (871/4253) showing metastasis. Most of them initiated prostatectomy (46.6%, 1983/4253) or regimens involving ADT therapy (45.7%, 1944/4253) for prostate cancer. In the present PCa cohort, 43.1% (1832/4253) of patients had hypertension, and half of them had poorly controlled blood pressure. With FRS stratification, as expected, a higher risk of CVD was related to aging and metabolic disturbance. However, we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT. This was in accordance with clinical practice, i.e., aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery. Among patients who underwent medical castration, only 4.0% (45/1118) received gonadotropin releasing hormone antagonists, in stark contrast to the grim situation of CVD prevalence and risk.Conclusions::PCa patients in China are diagnosed at an advanced stage. A heavy CVD burden was present at the initiation of treatment. Patients who accepted ADT-related therapy showed an original higher risk of CVD, but the awareness of cardiovascular protection was far from sufficient.

MicroRNA(miRNA)is a kind of small non-coding single stranded RNA that can participate in multiple biological processes.It also plays an important role in regulating the immune function of the body.Immune thrombocytopenia(ITP)is an autoim-mune disease,whose cause and deterioration are closely related to miRNA regulates immune function of CD4+T cells subsets.In ITP patients,different expression of miRNA can affect the immune function of CD4+T cells subsets,which causes not only unbalanced ex-pression of Th1/Th2,Th17/Treg and excessive differentiation of TFH,but also abnormal cytokine secretion furthermore.This paper summarizes the unbalanced mechanism of miRNA regulating immune function of CD4+T cells subsets in ITP,so as to provide inspira-tion for exploring the immunology and immunotherapy of ITP.

Background and Aims:Rupture is the most serious complication of abdominal aortic aneurysm,requiring rapid diagnosis,emergency surgery,and posing significant surgical challenges,with high mortality rates. Currently,there is very limited reporting on ruptured abdominal aortic aneurysm (rAAA) in our country,which presents numerous difficulties for the prevention and treatment of rAAA. This study collected the data of epidemiological characteristics,treatment outcomes,and prognosis of rAAA patients from multiple centers with a large sample size,analyzing the current status and trends of rAAA surgery in China over the past decade,aiming to provide reference for clinical practice.Methods:The clinical and follow-up data of 161 rAAA patients treated at five major vascular surgery centers (50 from Drum Tower Hospital Affiliated to the Medical School,Nanjing University;19 from the First Affiliated Hospital of Anhui Medical University;33 from the Second Affiliated Hospital of Nanchang University;31 from Qilu Hospital,Shandong University;and 28 from the First Affiliated Hospital of the University of Science and Technology of China) were retrospectively analyzed.Results:Among the 161 patients,124 (77.02％) were male and 37 (22.98％) were female,with an average age of 68.27 years. The median age at diagnosis was 70 years for males and 71 years for females. The overall mean aneurysm diameter was 7.11 cm,with males at 7.72 cm and females at 6.82 cm,showing a statistically significant difference (P<0.05). The main comorbidities were hypertension and coronary artery disease. Over 80％ of patients presented with abdominal pain as the initial symptom,while 15％ presented with low back pain,and 8 patients sought medical attention for dizziness or visual disturbances. Among the 161 patients,86 underwent open surgical repair (OSR),and 75 received endovascular aneurysm repair (EVAR). The proportion of EVAR has increased annually,reaching nearly 70％ in the past five years,and up to 90％ in patients aged over 70 years. All OSR procedures were performed under general anesthesia,while 20 EVAR cases used local anesthesia and 55 used general anesthesia. Compared to the OSR group,the EVAR group showed significant differences in operative time (231.77 min vs. 162.49 min),intraoperative blood transfusion volume (1578.56 mL vs. 843.87 mL),length of hospital stay (21.21 d vs. 15.34 d),ICU stay duration (8.28 d vs. 5.49 d),and hospitalization costs (108500 CNY vs. 132800 CNY) (all P<0.05). No significant differences were found between the EVAR and OSR groups in total complications or perioperative mortality rates (both P>0.05). The main causes of perioperative death included respiratory and circulatory failure,acute myocardial infarction,and severe infections. Postoperative follow-up was effectively conducted for 92 patients,with follow-up durations ranging from 10 to 142 months. Survival analysis revealed no significant difference in survival rate between the OSR and EVAR groups (P=0.3182).Conclusion:rAAA is a rare and high-risk disease,with certain clinical differences between male and female patients. The number of EVAR procedures has increased rapidly;however,EVAR has not shown a significant advantage over OSR in improving long-term survival rates.

Objective:To observe the clinical characteristics and guideline compliance of chronic obstructive pulmonary disease (COPD) patients with initial triple therapy in real-life world.Methods:This study is a cross-sectional study. The subjects of the study were COPD patients admitted to 13 hospitals in Hunan Province and Guangxi Zhuang Autonomous Region from December 2016 to December 2021. The initial treatment was triple inhaled drugs. The data collected included gender, age, diagnosis, body mass index (BMI), history of acute exacerbation (AE) in the past year, pulmonary function, COPD Assessment Test (CAT) score, modified British Medical Research Council Dyspnea Questionnaire (mMRC), inhaled drugs and other indicators. The characteristics and differences of COPD patients before and after 2020 were analyzed.Results:7 184 patients with COPD were enrolled in this study, including 2 409 COPD patients treated with initial triple therapy, accounting for 33.5%(2 409/7 184). Taking January 1st, 2020 as the cut-off point, 1 825 COPD patients (75.8%) received initial treatment with triple inhaled drugs before 2020 and 584 patients (24.2%) after 2020 were included in this study. Compared with COPD patients before 2020, the COPD patients after 2020 had higher FEV 1% [(40.9±15.5 )% vs (39.3±15.5)%, P=0.040], lower CAT [(15.8±6.5)point vs (17.5±6.2)point, P<0.001], less AE in the past year [1(0, 2)times vs 1(0, 2)times, P=0.001] and higher rate of non-AE [255(43.7%) vs 581(37.1%), P=0.006]. In addition, before 2020, patients with COPD were mainly treated with open triple drugs (1 825/1 825, 100%); after 2020, 306 patients (52.4%) received open triple inhaled drugs, and 278 patients (47.6%) received closed triple inhaled drugs. Conclusions:In real-life world, most of patients with COPD treated with triple therapy have severe lung function, obvious symptoms and high risk of acute exacerbation. The real-world prescribing of triple therapy in patients with COPD does not always reflect recommendations in guidelines and strategies, and overtreatment is common. After 2020, prescribing triple therapy for COPD patients is more positive and worse consistency with guideline.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
