Objective To compare the clinical outcomes of subxiphoid robot-assisted thoracoscopic surgery (SRATS) and intercostal robot-assisted thoracoscopic surgery (IRATS) in the treatment of anterior mediastinal tumors. Methods A retrospective analysis was conducted on patients with anterior mediastinal tumors who underwent robot-assisted surgery in the Department of Thoracic Surgery, Gansu Provincial Hospital, from May 2020 to July 2022. According to the surgical approach, patients were divided into an SRATS group and an IRATS group. Perioperative data were compared between the two groups. Results A total of 87 patients were included. There were 41 patients in the SRATS group [23 males, 18 females; mean age, (44.51±11.28) years] and 46 patients in the IRATS group [21 males, 25 females; mean age, (46.67±8.76) years]. Compared with the IRATS group, the SRATS group had significantly less intraoperative blood loss [(24.41±6.67) mL vs. (37.93±9.23) mL, P<0.001], shorter postoperative drainage duration [(1.73±0.59) days vs. (2.54±0.50) days, P<0.001], lower postoperative drainage volume [(94.46±34.08) mLvs. (116.72±24.90) mL, P=0.001], lower visual analogue scale (VAS) pain scores on postoperative day 1 [(3.66±0.76) points vs. (4.15±0.84) points, P=0.005] and day 3 [(2.41±0.59) points vs. (2.89±0.82) points, P=0.003], shorter postoperative hospital stay [(4.12±0.81) days vs. (4.98±1.02) days, P<0.001], and lower hospitalization costs [(4.51±0.65) ten thousand yuan vs. (4.86±0.68) ten thousand yuan, P=0.020]. There were no statistical differences between the two groups in operative time or incidence of postoperative complications (P>0.05). Conclusion Both SRATS and IRATS are safe and effective for the treatment of anterior mediastinal tumors. However, SRATS is less invasive and more conducive to enhanced postoperative recovery.

ObjectiveTo explore the impact of comprehensive vocational rehabilitation on quality of life and return-to-work outcomes for individuals with mild work-related disability. MethodsA longitudinal observational study was conducted. A total of 343 work-injured employees receiving comprehensive vocational rehabilitation intervention in Guangdong Work Injury Rehabilitation Hospital from June, 2023 to December, 2024 were selected. The 36-item Short Form Health Survey (SF-36) was adopted to assess their health-related quality of life at admission and discharge. All subjects were followed up within one year after discharge to collect their return-to-work status. The differences in each dimension score of SF-36 among patients with different return-to-work outcomes (return to original post, transfer to new post and non-return to work) were compared, and the independent influencing factors of return-to-work outcomes were identified. ResultsComprehensive vocational rehabilitation intervention significantly improved the scores of physical functioning (PF), role-physical (RP) and role-emotional (RE) among work-injured employees (P < 0.05). At discharge, compared with patients who failed to return to work, patients returning to original post obtained significantly higher scores in PF, RP, bodily pain (BP), general health (GH), vitality (VT), social functioning (SF) and mental health (MH), patients transferred to new post achieved significantly higher scores in PF, BP, GH and SF (P < 0.05). Taking non-return-to-work status as the reference category, the multinomial logistic regression model showed the adverse factors for return to original post included low educational attainment (college diploma or below), on-site placement service, increased lost workdays and low employment intention (pre-contemplation and contemplation stages); the protective factor was positive evaluation of health transition (HT); for patients transferred to new posts, adverse factors were low employment intention (pre-contemplation stage) and increased lost workdays, while protective factors covered on-site placement service and positive HT evaluation. ConclusionComprehensive vocational rehabilitation can improve the quality of life for injured workers. Better quality of life is positively associated with return-to-work outcomes. HT, education level, job placement mode, lost workdays and employment willingness are independent factors impacting return-to-work outcomes.

"Spirit turns but does not reverse； if it reverses， it ceases to turn" originates from the Plain Questions： Discussion on Essential Jade Plates （《素问·玉版论要篇》）. It profoundly summarizes the objectivity of life as a phenomenon subject to the laws of the universe and nature， while also expressing the subjectivity of individuals possessing systematic， stable， and ordered biological rhythms. In light of relevant ancient philosophical insights， the theory of "spirit turns but does not reverse； if it reverses， it ceases to turn" embodies the principles of constant motion in life， change according to dao （道）， orderly progression， and the rule that reversal disrupts continuity. In clinical diagnosis and treatment， one should adopt the therapeutic principle of regulating spirit to promote "spirit turning". Guiding along the trend and acting in accordance with the natural momentum must be adopted to maintain the operation of spirit turning. Adhering to constancy while recognizing variability， and prioritizing harmony above all， should be employed to ensure the orderly progress of spirit turning. Regulating qi movement serves as the driving force behind facilitating spirit turning. This will provide clinical insights and theoretical foundations for treating diseases through the concept of "regulating spirit".

ObjectiveTo investigate the mechanism by which Kangxian Yixin prescription regulates the circular RNA 0006719 （circ0006719）/microRNA 6852-5p （miR-6852-5p）/transforming growth factor-β₁ （TGF-β₁）/Smad axis to ameliorate myocardial fibrosis in rats with dilated cardiomyopathy （DCM） and angiotensin Ⅱ （Ang Ⅱ）-induced activation of cardiac fibroblasts （CFs）. MethodsA DCM rat model was established by administration of furazolidone. The rats were divided into normal group， model group， captopril （CAP， 10.1 mg·kg^-1·d^-1） group， and low-， medium-， and high-dose Kangxian Yixin prescription groups （0.9， 1.8， 3.6 g·kg^-1·d^-1）， with 15 rats in each group. After modeling， the treatment groups received corresponding drug solutions by gavage， whereas the normal and model groups received an equal volume of normal saline for 60 consecutive days. Echocardiography was used to measure left ventricular end-systolic diameter （LVESD）， left ventricular end-diastolic diameter （LVEDD）， left ventricular ejection fraction （LVEF）， and left ventricular fractional shortening （LVFS）. Transmission electron microscopy （TEM）， hematoxylin-eosin （HE） staining， and Masson staining were used to observe myocardial ultrastructure， pathological changes， and collagen deposition. Immunohistochemistry （IHC） was used to detect the protein expression of collagen type Ⅰ alpha 1 （Col1A1） and collagen type Ⅲ（Col Ⅲ） in myocardial tissue. Real-time quantitative polymerase chain reaction （Real-time PCR）， Western blot， and fluorescence in situ hybridization （FISH） were used to detect the expression and localization of circ0006719， miR-6852-5p， fibrosis-related molecules， and TGF-β₁/Smad pathway-related molecules in myocardial tissue and CFs. CFs from neonatal rats were isolated and cultured in vitro. Cell Counting Kit-8 （CCK-8） assay was used to determine the optimal concentration of Kangxian Yixin prescription for subsequent intervention. An Ang Ⅱ-induced CF activation model was established， and the cells were divided into normal group， Ang Ⅱ group， Ang Ⅱ+CAP group， Ang Ⅱ+Kangxian Yixin prescription group， and Ang Ⅱ+Kangxian Yixin prescription+miR-6852-5p inhibitor group. CF viability and fibrosis-related molecular expression were detected. RNA immunoprecipitation （RNA IP） and dual-luciferase reporter assays were used to verify the targeting relationship between circ0006719 and miR-6852-5p. ResultsCompared with the normal group， the model group showed significantly increased LVESD and LVEDD， significantly decreased LVEF and LVFS， aggravated myocardial ultrastructural and histopathological injury， and significantly increased collagen volume fraction （CVF） in myocardial tissue （P<0.01）. The expression of circ0006719， Col1A1 mRNA， Col ⅢmRNA， and Col1A1， Col Ⅲ， TGF-β₁， Smad3， and Smad4 proteins in myocardial tissue was significantly upregulated， whereas miR-6852-5p expression and Smad7 protein expression were significantly downregulated （P<0.01）. Compared with the model group， the CAP group and the high- and medium-dose Kangxian Yixin prescription groups showed varying degrees of improvement in cardiac function， myocardial fibrosis， circ0006719/miR-6852-5p expression， and TGF-β₁/Smad pathway-related indicators， with more pronounced improvements in the CAP group and the high-dose Kangxian Yixin prescription group （P<0.05， P<0.01）. In in vitro experiments， 2.0 g·L^-1 was determined as the optimal concentration of Kangxian Yixin prescription for subsequent intervention. Compared with the normal group， the Ang Ⅱ group showed significantly increased CF viability， significantly upregulated expression of circ0006719， Col1A1 mRNA， α-smooth muscle actin （α-SMA） mRNA， and Col1A1， α-SMA， TGF-β₁， Smad3， and Smad4 proteins in CFs， and significantly downregulated miR-6852-5p expression and Smad7 protein expression （P<0.01）. Compared with the Ang Ⅱ group， the Ang Ⅱ+CAP group and the Ang Ⅱ+Kangxian Yixin prescription group showed markedly decreased CF viability and fibrosis-related mRNA and protein expression， markedly increased miR-6852-5p expression， and markedly attenuated TGF-β₁/Smad pathway activation （P<0.05， P<0.01）. Compared with the Ang Ⅱ+Kangxian Yixin prescription group， the Ang Ⅱ+Kangxian Yixin prescription+miR-6852-5p inhibitor group showed significantly increased CF viability （P<0.01）， markedly increased expression of circ0006719， Col1A1 mRNA， and Col1A1， TGF-β₁， and Smad4 proteins in CFs， and markedly decreased miR-6852-5p expression （P<0.05， P<0.01）. RNA IP and dual-luciferase reporter assays showed a targeting binding relationship between circ0006719 and miR-6852-5p （P<0.01）. ConclusionKangxian Yixin prescription may alleviate myocardial collagen deposition and myocardial fibrosis， improve cardiac function in DCM rats， and inhibit Ang Ⅱ-induced abnormal activation of CFs. Its mechanism may be associated with downregulation of circ0006719， restoration of miR-6852-5p expression， and inhibition of the TGF-β₁/Smad pathway.

In recent years， the incidence of depression among adolescents has increased significantly， becoming a serious global public health problem. There is a close relationship between adolescent depression and lipid metabolism abnormalities. However， the mechanisms underlying this association have not been fully elucidated. This article provides a review of the mechanisms and interventions linking adolescent depression and lipid metabolism abnormalities， aiming to offer new ideas for interventions in adolescent depression. Using computerized searches of the China National Knowledge Infrastructure （CNKI）， Wanfang Data， PubMed， and Web of Science， studies on the mechanisms and interventions related to adolescent depression and lipid metabolism were collected， with the search period extending up to October 10， 2025. Two researchers independently conducted literature screening and extracted basic information from the included studies. A total of 12 original studies were included. The results indicate that adolescent depression is associated with certain lipid metabolites. Neurobiological factors， immune inflammation， oxidative stress， and gut microbiota imbalance play important roles in this association. In addition， lipid metabolites such as omega-3 polyunsaturated fatty acids （ω-3 PUFAs） have a significant ameliorating effect on adolescent depression. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGSP013）； Shenzhen Science and Technology Program （number， 20210617155253001）］

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To explore the role and underlying mechanism of the transcriptional coactivator with PDZ-binding motif(TAZ)and a histone variant of acute histone H2A(H2A.Z)in the repair of hypoxia-induced lung injury.Methods A mouse model of hypoxic lung injury was established by being placed in a hypoxia chamber(simulating an altitude of 5 800 m)for 4 d.HE staining was used to observe the severity of lung injury.A hypoxia model of murine alveolar epithelial cells(murine lung epithelial-12,MLE12)was constructed by treating the cells in a hypoxia workstation(1%O2 concentration)for 24 h.Western blotting was employed to detect TAZ expression.The proliferation of alveolar epithelial cells(AECs)was evaluated by CCK-8 assay.Co-immunoprecipitation(Co-IP)assay was utilized to verify the interaction between TAZ and H2A.Z.CUT&Tag sequencing was performed to determine the effect of TAZ on the chromatin deposition of H2A.Z.Results Hypoxia significantly induced alveolar atrophy and inflammatory infiltration in mouse lung tissues(P＜0.01).Hypoxia significantly up-regulated the protein level of TAZ in MLE12 cells(P＜0.05).CCK-8 assay showed that knockdown of TAZ significantly reduced the proliferative capacity of AECs(P＜0.01).Co-IP assay confirmed the physical interaction between TAZ and H2A.Z.CUT&Tag sequencing revealed that hypoxia promoted the deposition of H2A.Z on chromatin(31 817 peaks under normoxia,44 078 peaks under hypoxia),which was partially reversed by TAZ knockdown(37 840 peaks).Conclusion Hypoxia significantly up-regulates the expression of TAZ,which combines with H2A.Z and promotes the deposition of H2A.Z on chromatin,thus enhancing the proliferation of AECs in response to hypoxic injury.
