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.

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::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.

Pulmonary hypertension (PH) is a life-threatening disease characterized by pulmonary vascular remodeling, in which hyperproliferation of pulmonary artery smooth muscle cells (PASMCs) plays an important role. The cysteine 674 (C674) in the sarcoplasmic/endoplasmic reticulum Ca²⁺ ATPase 2 (SERCA2) is the critical redox regulatory cysteine to regulate SERCA2 activity. Heterozygous SERCA2 C674S knock-in mice (SKI), where one copy of C674 was substituted by serine to represent partial C674 oxidative inactivation, developed significant pulmonary vascular remodeling resembling human PH, and their right ventricular systolic pressure modestly increased with age. In PASMCs, substitution of C674 activated inositol requiring enzyme 1 alpha (IRE1α) and spliced X-box binding protein 1 (XBP1s) pathway, accelerated cell cycle and cell proliferation, which reversed by IRE1α/XBP1s pathway inhibitor 4μ8C. In addition, suppressing the IRE1α/XBP1s pathway prevented pulmonary vascular remodeling caused by substitution of C674. Similar to SERCA2a, SERCA2b is also important to restrict the proliferation of PASMCs. Our study articulates the causal effect of C674 oxidative inactivation on the development of pulmonary vascular remodeling and PH, emphasizing the importance of C674 in restricting PASMC proliferation to maintain pulmonary vascular homeostasis. Moreover, the IRE1α/XBP1s pathway and SERCA2 might be potential targets for PH therapy.

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.

Lung cancer is the malignancy with the highest mortality rate worldwide. Malignant pleural effusion (MPE) caused by advanced lung cancer severely affects the quality of life and prognosis of patients. Tumor-associated genetic testing is the basis for making precise treatment decisions. There are some risks of tissue biopsy, and it is difficult to sample repeatedly. Due to its non-invasive and can reflect the full profile of tumor gene characteristics, liquid biopsy is increasingly used in the diagnosis and treatment of lung cancer. Because of the extremely low DNA level of circulating tumor, the sensitivity and specificity of liquid biopsy based on blood samples are limited. Tumor cells is enriched in MPE. The detection of cell-free DNA, extracellular vesicles and microRNA in MPE will be helpful to the diagnose, treatment and assess prognosis of patients with lung cancer. This review aims to discuss the research progress of liquid biopsy based on MPE in the diagnosis and treatment of lung cancer patients.

Objective: To assess the diagnostic performance of contrast-enhanced spectral mammography (CESM) in suspected breast lesions. Methods: A total of 97 patients with suspected breast cancer identified by clinical examination or screening underwent two-views CESM examination on the basis of digital breast tomosynthesis (DBT) combined with full-field digital mammography (FFDM), and they were finally confirmed by biopsy or pathology. Three senior radiologists analyzed images, including lesion visibility, lesion characteristics, enhancement type, degree of enhancement, BIRDS classification, etc. Finally, based on the pathology, we compared the CESM+DBT+FFDM and DBT+FFDM two models according to sensitivity, specificity and ROC for diagnostic performance. Results: There were a total of 120 lesions. Eighty-nine lesions were malignant, 31 benign; CESM was not enhanced in 2 cases, mild enhancement was performed in 22 cases, moderately intensive in 15 cases, highly intensive in 81 cases, and 2 cases were not enhanced; mass-enhanced in 96 cases, including ring-enhanced in 12 cases, 22 cases of non-mass type. The sensitivities of the combination of CESM and not combination of CESM were 91.0% and 80.9%, respectively, and the specificities were 93.5% and 87.1%, respectively. The area under the ROC curve of combination of CESM was higher than the without combination of CESM (0.923 and 0.900, P<0.05), The difference was statistically significant. Conclusion For suspicious lesions, CESM examination can improve the diagnosis accuracy of breast cancer.
