Objective:To investigate the employment status of graduates from standardized residency training in Hubei Province, China and provide strategies for improving the quality of medical education after graduation.Methods:A cross-sectional survey was conducted in August 2022. Graduates from the first and second batches of 29 national standardized residency training bases in Hubei Province from 2017 to 2022 were surveyed using an online questionnaire. A total of 4 344 valid responses were collected, with a response rate of 95.78%. The survey was conducted online using a self-designed questionnaire titled "Employment Status Survey of Residency Training Graduates in Hubei Province".Results:Among the graduates, 3 505 (80.69%) were directly employed after completing the training, while 428 (9.85%) were unemployed. The primary reason for unemployment was ongoing job searching or application processes (268, 62.61%). Of the employed graduates, 3 082 (87.63%) worked in hospitals, including 1 799 (58.37%) in grade A tertiary hospitals, 485 (15.74%) in grade B tertiary hospitals, and 618 (20.05%) in grade A secondary hospitals. A total of 2 936 (83.48%) graduates worked in physician positions aligned with their training specialties, while 500 (14.22%) worked in physician positions unrelated to their training specialties. Additionally, 1 349 (38.35%) graduates reported that their current income met their personal consumption needs, while 2 138 (61.65%) stated that their income barely met or failed to meet their needs. Moreover, 2 466 (70.12%) graduates felt that their current work status generally met their expectations, while 968 (27.52%) reported that it fell below their expectations. Of the graduates, 2 927 (67.40%) believed that the residency training significantly helped them perform their current jobs, whereas 1 417 (32.60%) perceived the training as providing limited or moderate assistance.Conclusions:The re-employment rate of residency training graduates in Hubei Province is relatively high. However, the recognition of standardized residency training and the salary levels of re-employment are relatively low.

Tooth pulpitis is a prevalent oral disorder. Understanding the underlying mechanisms of pulpitis and developing effective treatment strategies hold great significance. Ferroptosis has recently emerged as a new form of cell death, but the role of ferroptosis in pulpitis remains largely unknown. In our study, single-cell RNA sequencing (scRNA-seq) was used to identify cellular heterogeneity between 3 pulpitis tissue and 3 healthy pulp tissue, and explored ferroptosis occurrence in pulpitis tissue and inflamed dental pulp cells (DPCs). In scRNA-seq, 40 231 cells (Pulpitis: 17 814; Healthy pulp: 22 417) were captured, and visualized into 12 distinct cell clusters. Differentially expressed ferroptosis-related genes (DE-FRGs) were almost presented in each cluster in pulpitis vs healthy pulp. ROS and Fe2+ levels significantly rose, and immunohistochemistry showed low expression of GPX4 and high expression of PTGS2 in pulpitis. In LPS-stimulated DPCs, thymosin α1 increased the expression of GPX4 and FTL, and decreased expression of TNF-α, IL-1β, IL-6, and Fe2+ levels. In rat pulpitis models, both prothymosin α (PTMA, precursor of thymosin α1) gelatin sponge placed at the hole of pulp (LPS-P(gs)) and PTMA injection in pulp (LPS-P(i)) significantly reduced infiltration of inflammatory cells and expression of PTGS2, and increased the expression of GPX4. In RNA sequencing, the expression of DE-FRGs were reversed when thymosin α1 were added in LPS-stimulated DPCs. Collectively, single-cell atlas reveals cellular heterogeneity between pulpitis and healthy pulp, and ferroptosis occurrence in pulpitis. Thymosin α1 may reduce ferroptosis in DPCs to alleviate pulpitis and thus potentially has the ability to treat pulpitis.

Objective To investigate the characteristics and influencing factors of mental health status of permanent residents in Yichang, Hubei Province. Methods A total of 9 576 permanent residents aged 18 years and older from Yichang City were selected by a multistage random sampling method between June and October 2022. The PHQ-9 was used to assess the residents’ depressive symptoms, the GAD-7 was used to assess their anxiety symptoms, the ISI was used to assess their insomnia status, and the PCL-5 was used to assess their stress status. The influence factors of depression and anxiety were analyzed using χ2 test and logistic regression. Results A total of 9 122 valid questionnaires were completed. The detection rate of depression, anxiety, insomnia, and stress symptoms were 29.98%, 19.03%, 11.97% and 1.58%, respectively. Gender, education level, monthly family income, self-rated health status, mental health literacy level, total GAD-7 score, total ISI score, and total PCL-5 score were the main factors that caused residents' anxiety symptoms, while gender, education level, self-rated health status, total PHQ-9 score, total ISI score, and total PCL-5 score were the main factors that caused residents' anxiety symptoms. Conclusion The prevalence of depression and anxiety is high among the permanent residents in Yichang, while the situation of insomnia and stress is relatively good. Measures such as improving the level of mental health literacy can be taken to improve mental health level of residents in Yichang.

Objective:To evaluate the feasibility of abandoning prophylactic abdominal drainage in patients undergoing minimally invasive minor hepatectomy based on a propensity score matching (PSM) study.Methods:Retrospective review of a prospectively collected database of patients undergoing minimally invasive minor hepatectomy from July 2022 to May 2023 at the Department of Hepatopancreatobiliary Surgery and Minimally Invasive Surgery, Zhejiang Provincial People's Hospital. A total of 108 patients were enrolled, including 48 males and 60 females, aged (60.8±13.7) years old. According to whether the abdominal drainage tube was prophylactically placed intraoperatively, patients were divided into two groups: the drainage group (with prophylactic placement of abdominal drainage tubes, n=76); the no-drainage group (without prophylactic placement of abdominal drainage tubes, n=32). PSM was used to compare the perioperative data between the groups, including extent of liver resection, intraoperative blood loss, operative time, and postoperative complications. Postoperative survival status within 90 days was followed up through telephone review. Results:Before PSM, the two groups differed significantly on age and the history of hypertension (both P<0.05). After PSM, there were 23 patients in each group. Patients in the two groups showed comparable results regarding the intraoperative parameters including the surgical method, pathological types, the number and maxium diameter of hepatic lesions, the extent and complexity of liver resection, and the duration of hepatic inflow occlusion (all P>0.05). No postoperative intra-abdominal bleeding occurred in either group. The incidences of postoperative complications were comparable between the groups, including fever, bile leakage, incision infection, and abdominal acupuncture for drainage (all P>0.05). After PSM, compared to patients wothout prophylactic abdominal drainage, prophylactic abdominal drainage group showed a decreased white blood cell counts on postoperative day 1 [9.39(6.30, 10.58)×10 12/L vs. 13.19(10.15, 14.90)×10 12 /L, P=0.006] and a shorter length of postoperative hospital stay [4(3, 5) d vs. 5(4, 5) d, P=0.033]. No postoperative death within 90 days occurred in either group. Conclusion:In minimally invasive minor hepatectomy, abandoning prophylactic abdominal drainage could be feasible, which facilitates fast recovery without increasing the incidence of postoperative fever, perihepatic fluid accumulation and postoperative abdominal acupuncture for drainage.

Exosomes are extracellular vesicles secreted by cells containing various biologically active substances, including proteins, lipids and nucleic acids. In the brain, exosomes participate in many physiological processes, such as neurogenesis, synaptic plasticity, and intercellular communication, and are closely associated with the development of depression. As exosomes can traverse the blood-brain barrier and be extracted in various peripheral body fluids, exosomes of central nervous system origin may facilitate understanding the pathophysiology of brain-related disorders. This review summarizes the role of exosomes in the common pathogenesis of depression, and it also discusses the great potential as biomarkers for early depression diagnosis and precision medicine, aiming to provide novel perspectives for depression research.
