Objective To systematically evaluate the efficacy and safety of video-assisted thoracoscopic surgery (VATS) with different numbers of ports in the treatment of spontaneous pneumothorax. Methods We conducted a comprehensive search of CNKI, PubMed, The Cochrane Library, Web of Science, EMbase, Wanfang Data, and the Chinese Medical Journal Full-text Database for clinical controlled trials on VATS with different port numbers for spontaneous pneumothorax, from their inception to March 2023. Two researchers independently screened the literature and assessed its quality.The Newcastle-Ottawa Scale (NOS) was used to assess the methodological quality of cohort and case-control studies, and the Cochrane risk-of-bias tool was used to evaluate randomized controlled trials (RCT). Meta-analysis was performed using RevMan 5.4.1 software. Results A total of 107 studies were included, comprising 35 RCT, 2 cohort studies, and 70 case-control studies. All cohort and case-control studies included in the analysis had NOS scores≥7. The meta-analysis revealed that compared to two-port VATS (2P-VATS) and three-port VATS (3P-VATS), single-port thoracoscopic surgery (SPTS) was associated with less intraoperative blood loss (SMD=–1.58, 95%CI: –1.93 to –1.22, P<0.001; and SMD=–1.59, 95%CI: –2.03 to –1.14, P<0.001, respectively), shorter postoperative hospital stay (SMD=–1.05, 95%CI: –1.29 to –0.82, P<0.001; and SMD=–1.08, 95%CI: –1.39 to –0.77, P<0.001), shorter duration of postoperative chest tube drainage (SMD=–0.75, 95%CI: –1.00 to –0.50, P<0.001; and SMD=–1.23, 95%CI: –1.72 to –0.75, P<0.001), fewer postoperative complications (OR=0.34, 95%CI: 0.26 to 0.45, P<0.001; and OR=0.47, 95%CI: 0.33 to 0.68, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P<0.05). The operative time for SPTS was shorter than that for 2P-VATS (SMD=–0.53, 95%CI: –0.90 to –0.16, P=0.005) but showed no significant difference compared to 3P-VATS (P=0.21). When comparing 2P-VATS with 3P-VATS, 2P-VATS demonstrated less intraoperative blood loss (SMD=–1.02, 95%CI: –1.81 to –0.22, P=0.01), shorter postoperative hospital stay (SMD=–0.59, 95%CI: –1.11 to –0.06, P=0.03), shorter duration of chest tube drainage (SMD=–0.46, 95%CI: –0.85 to –0.08, P=0.02), fewer postoperative complications (OR=0.36, 95%CI: 0.22 to 0.59, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P≤0.05). Conclusion Both SPTS and 2P-VATS are effective and safe surgical options for spontaneous pneumothorax, deserving further promotion and application in clinical practice. However, due to limitations in the quantity and quality of the included studies, more large-sample, high-quality research is needed to validate these findings.

Objective To systematically evaluate the efficacy of immune checkpoint inhibitors (ICIs) in treating esophageal cancer patients of different genders. Methods Computer searches were conducted on PubMed, Cochrane Library, and Embase databases to collect randomized controlled trial (RCT) on ICIs treatment for esophageal cancer patients from the establishment of the databases to January 25, 2024. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. The outcome indicators were overall survival (OS) and progression-free survival (PFS), and RevMan 5.4 software was used for meta-analysis. The modified Jadad scoring scale was used to evaluate the quality of the included literature. Results A total of 10 RCT involving 5364 esophageal cancer patients were included in this study, with 2684 patients in the trial group and 2680 patients in the control group. The Jadad scores of the included literature were all ≥6 points, indicating high-quality RCT. Meta-analysis results showed that female esophageal cancer patients receiving ICIs treatment [HR=0.72, 95%CI (0.59, 0.87), P<0.001] had a more significant median OS prolongation than male patients [HR=0.73, 95%CI (0.68, 0.78), P<0.001]; while male patients [HR=0.57, 95%CI (0.52, 0.64), P<0.001] had a more significant PFS prolongation than female patients [HR=0.72, 95%CI (0.55, 0.94), P=0.01]. Female patients treated with ICIs alone [HR=0.66, 95%CI (0.50, 0.87), P=0.003] had a more significant median OS prolongation than male patients [HR=0.79, 95%CI (0.72, 0.87), P<0.001]; while male patients receiving ICIs combined with chemotherapy [HR=0.67, 95%CI (0.61, 0.74), P<0.001] had a more significant median OS prolongation than female patients [HR=0.77, 95%CI (0.59, 1.01), P=0.06]. Conclusion Female patients receiving ICIs have a slight advantage in OS compared to male patients, while male patients have an advantage in PFS. Male patients receiving ICIs combined with chemotherapy have better survival benefits than female patients, while female patients using ICIs monotherapy have better survival benefits than male patients.

Objective: To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies. Methods: From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects. Results: Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05). Conclusion Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

Background As one of the most severe occupational diseases in China, pneumoconiosis is significantly burdened by its complications, which adversely affects patients' quality of life. Objective To identify the influencing factors of complications in pneumoconiosis and to construct an early prediction model for pneumoconiosis complications, providing theoretical guidance for clinical diagnosis, treatment, and rehabilitation. Methods A case-control study was conducted using data from the Chongqing 5G Pneumoconiosis Rehabilitation Management Information Platform. A total of 1872 pneumoconiosis patients with complications, who received rehabilitation at various rehabilitation stations in Chongqing from January 2021 to December 2024, were enrolled as the case group. Concurrently, 2348 patients without complications from the same platform and period were included as the control group. Univariate analysis, LASSO regression, and logistic regression were employed to identify influencing factors for complications. An extreme gradient boosting (XGBoost) model was trained using ten-fold cross-validation to predict pneumoconiosis complications. The SHapley Additive exPlanations (SHAP) method was applied for model visualization. Results The analysis of influencing factors revealed that increased age, silicosis type, advanced stage of pneumoconiosis, dependence in activities of daily living, abnormal muscle strength, increased dyspnea index, presence of cough, viscous sputum, impaired cardiac function, severe abnormality in the 6-minute walk test (6MWT), and increased Borg score were risk factors for complications (P<0.05). The XGBoost model demonstrated an area under the curve (AUC) of receiver operating characteristic of 0.718, and a Brier score of 0.211 for the calibration curve. Decision curve analysis demonstrated a superior net benefit within the threshold probability range of 0.2 to 1.0 compared to "all-patient intervention" and "no-patient intervention" strategies, indicating good predictive performance and significant clinical utility. SHAP visualization identified the top six important features as Borg score, age, 6MWT, muscle strength, pneumoconiosis stage, and cough symptoms. Conclusion Multiple factors influence the occurrence of complications in pneumoconiosis patients. Clinical attention should be focused on elderly patients with decreased cardiopulmonary reserve, pronounced respiratory symptoms, and diminished muscle strength. The XGBoost model demonstrates satisfactory discrimination, calibration, and clinical applicability in predicting pneumoconiosis complications and may serve as a useful reference for clinical decision-making.

Objective: To systematically evaluate the therapeutic efficacy and maintenance effects of digital psychological therapies on depressive symptoms among adolescents, so as to provide a reference for clinical practice. Methods: Randomized controlled trial(RCT) investigating digital psychological therapies to improve depressive symptoms among adolescents were searched across databases, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang database, VIP database, and SinoMed, from database inception to November 20, 2025. Following literature screening, quality assessment, and data extraction, a Meta analysis was performed using Stata 18.0 software. Results: A total of 20 studies involving 2 042 adolescents aged 11-19 were included. The Meta analysis revealed that digital psychological therapies significantly alleviated depressive symptoms in adolescents ( SMD =-0.59, 95% CI =-0.85 to -0.32, P <0.01). The therapeutic effect was sustained at long term follow up ( SMD =-0.21, 95% CI =-0.34 to -0.09, P <0.01). Furthermore, depression scores in the intervention group showed a continued decrease from post intervention to long term follow up ( SMD =-0.28, 95% CI =-0.41 to -0.14, P <0.01). Egger s linear regression test indicated possible publication bias (Kendall s tall=0.28, P <0.01). Conclusions Digital psychological therapies can effectively improve depressive symptoms among adolescents, with stable long term efficacy. However, current evidence remains limited and exhibits substantial heterogeneity. Therefore, further large sample, high quality RCTs are warranted to validate the effectiveness of this intervention.

ObjectiveTo investigate the efficacy and safety of simplified diagnosis and treatment strategies and regimens in the treatment of patients with human immunodeficiency virus （HIV）/hepatitis C virus （HCV） co-infection. MethodsThis multicenter prospective real-world study was conducted among 198 patients with HIV/HCV co-infection who received hepatitis C treatment in 10 designated primary hospitals for hepatitis C in Yuxi， China from July 2023 to June 2024， and according to whether genotype detection was performed， they were divided into genotype detection group with 122 patients and non-genotype detection group with 76 patients. The patients were observed in terms of sustained virologic response at 12 weeks （SVR12）， safety， and liver biochemical parameters. Propensity score matching was used to match the two cohorts， using caliper matching （caliper value = 0.02） at a ratio of 1∶1. The independent-samples t test or the Wilcoxon signed-rank test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between groups. ResultsAmong the 122 patients in the genotype detection group， 63.11% （77/122） had genotype 3， while the non-genotype detection group had 76 patients； both groups achieved an SVR12 rate of 100%. From baseline to 12 weeks after treatment， both groups had a significant increase in the serum level of albumin， significant reductions in the serum levels of total bilirubin， alanine aminotransferase， aspartate aminotransferase， and alpha-fetoprotein， and a significant reduction in FibroScan value （all P<0.05）. A total of 54 patients （27.27%） experienced at least one adverse reaction， and anemia was the most common adverse reaction （38 patients， 19.19%）， with an incidence rate of 50.00% （33/66） in patients with liver cirrhosis. HIV viral load remained <50 IU/mL before and after treatment， and there was no significant change in CD4⁺ T lymphocyte count after treatment （Z=-0.969， P=0.202）. Compared with the genotype detection group， the non-genotype detection group had a significantly shorter time from positive HCV RNA testing to treatment initiation （4±2 days vs 19±4 days， t=5.321， P<0.05） and significantly lower testing costs （618±97 yuan vs 789±129 yuan， t=3.661， P<0.05）. ConclusionFor patients with HIV/HCV co-infection， the simplified diagnosis and treatment strategies can achieve a relatively high SVR12 rate， improve biochemical indicators， and effectively reduce time cost and economic burden， with a favorable safety profile.

AIM To investigate the protective effects of Shuangyi Qushi Tongluo Capsules(Shuangyi Capsules)on Dexamethasone(Dex)induced osteoporosis in mice.METHODS The C57BL/6J mice were randomly divided into the control group,the model group,the Xianling Gubao Capsules group(1.5 g/kg),and the low-dose,moderate-dose,and high-dose Shuangyi Capsules groups(0.6,1.2,and 2.4 g/kg).The mouse model of osteoporosis was induced by 8-week intraperitoneal injection of Dex sodium phosphate injection(5 mg/kg).The mice had their femur osteogenesis observed with hematoxylin and eosin(HE)staining and tartrate-resistant acid phosphatase(TRAP)staining;their serum alkaline phosphatase(ALP)and osteocalcin(BGP)activities detected by ELISA;their femoral mRNA expressions of Col-Ⅰ,OCN,and OPN detected by RT-qPCR;and their femoral protein expressions of OPG and RANKL detected by Western blot.Upon the MC3T3-E1 cells exposed to Dex and Shuangyi Capsules,their viability was evaluated by CCK-8 assay;their mineralization determined by alkaline phosphatase staining and alizarin red staining(ARS);and their intracellular ROS level detected using DCFH-DA probe.RESULTS Compared with the model group,Shuangyi Capsules groups demonstrated improved fracture of femoral trabeculae and reduced number of osteoclasts;increased serum ALP and BGP activities(P＜0.05,P＜0.01);increased femoral expressions of Col-Ⅰ mRNA and OPG protein(P＜0.05,P＜0.01);and decreased RANKL protein expression(P＜0.05).Compared with the MC3T3-E1 cells stimulated by Dex,those underwent further treatment of Shuangyi Capsules demonstrated increased cell viability and ALP activity(P＜0.05,P＜0.01);increased mineralization and calcium nodule formation;increased expressions of Col-Ⅰ,OCN,OPN mRNA and OPG protein(P＜0.05,P＜0.01);decreased RANKL protein expression(P＜0.05,P＜0.01);and reduced ROS levels.CONCLUSION Shuangyi Capsules ameliorate Dex-induced osteoporosis in mice by suppressing osteoclast overactivation,enhancing osteoblast activity,and stimulating bone formation through modulation of Col-Ⅰ,OCN,OPN mRNA and OPG/RANKL protein levels.

BACKGROUND:As an essential trace element for body growth and development,copper participates in many processes such as redox process,energy generation,signal transduction and bone metabolism.The imbalance of copper homeostasis in diabetic patients will lead to the increase of oxidative stress and the impairment of antioxidant mechanism,which stimulate the production of inflammatory mediators and inflammatory factors,and thus lead to cytotoxicity and body damage.In recent years,the role of copper in diabetes has gradually attracted attention,and some studies have confirmed that copper plays a key regulatory role in the pathological process of diabetes.OBJECTIVE:To summarize the current progress in the role of copper in systemic complications of diabetes and provide some theoretical reference for its future research and treatment.METHODS:The first author searched PubMed,Web of Science,CNKI and WanFang databases for literature related to the role of copper in systemic complications of diabetes.The search terms were"copper,Cu,diabetes,diabetic complications,diabetic cardiomyopathy,diabetic nephropathy,diabetic retinopathy,diabetic osteoporosis,diabetic periodontitis"in English and Chinese,respectively.After screening,95 articles were included in the review.RESULTS AND CONCLUSION:(1)Copper is involved in the occurrence and development of diabetic complications and most of the damage caused by copper to the body is due to interference with the body's redox level.(2)In diabetic cardiomyopathy,increased Cu2+in the corpuscular circulation and impaired uptake of copper ions by cardiomyocytes,the accumulation of redox-active Cu2+and ceruloplasmin outside the cardiomyocyte induces copper oxidative stress in cardiomyocytes,leading to acute cardiac impairment.(3)In diabetic nephropathy,the toxic effect of excessive copper leads cause granular degeneration and vacuolar degeneration of renal tubular epithelial cells and proximal tubular necrosis,eventually leading to chronic or acute renal failure.(4)Excessive copper in diabetic patients can produce reactive oxygen species and directly or indirectly affect the function of copper protein with antioxidant function,thus damaging retinal cells.(5)In patients with diabetic osteoporosis,accumulated copper induces lipid peroxidation and interferes with bone metabolism.Copper acts on osteoblasts mainly through inhibition of superoxide dismutase,glutathione peroxidase,and alkaline phosphatase activities.(6)Excessive copper exacerbates inflammatory changes in periodontal tissue by promoting inflammatory responses.

BACKGROUND:Exosomes have been confirmed to be closely related to cartilage degeneration in osteoarthritis.However,the role and mechanism of exosome-derived genes in cartilage degeneration of osteoarthritis have not been fully elucidated.OBJECTIVE:Bioinformatics analyses were used to screen the genes related to cartilage degeneration in the synovial exosomes of patients with osteoarthritis,and to determine their biological functions and signaling pathways in order to provide new therapeutic targets for delaying cartilage degeneration in osteoarthritis.METHODS:Firstly,osteoarthritis-related exosome dataset GSE185059 and cartilage degeneration dataset GSE114007 were downloaded from Gene Expression Omnibus(GEO)database to screen exosome-derived cartilage degeneration related genes.GO functional and KEGG pathway enrichment analyses were performed based on the screened exosome-derived cartilage degeneration related genes.Protein-protein interaction network was drawn and Ingenuity Pathway Analysis(IPA)was conducted to screen and obtain key exosome-derived cartilage degeneration-related genes.Finally,qRT-PCR was used to verify the expression of key genes in osteoarthritis cartilage tissue and interleukin-1β stimulated chondrocyte models.RESULTS AND CONCLUSION:(1)There were 831 differentially expressed genes in the GSE185059 dataset and 5 323 differentially expressed genes in the GSE114007 dataset.A total of 94 exosome-derived cartilage degeneration related genes were screened after the intersection of these differentially expressed genes,of which 51 genes were down-regulated and 43 genes were up-regulated.(2)GO functional enrichment analysis showed that the up-regulated genes were mainly involved in the positive regulation of cell-cell adhesion,the positive regulation of T cell activation,and chronic inflammatory response,while the down-regulated genes were mainly involved in biological processes such as cell aggregation,cartilage differentiation and development,and skeletal system morphogenesis.(3)KEGG pathway enrichment analysis showed that exosome-derived cartilage degeneration-related genes were mainly involved in tryptophan enrichment metabolism,vitamin B6 metabolism,and leukocyte transendothelial migration.(4)The constructed protein-protein interaction network confirmed the existence of multiple interaction relationships among exosome-derived cartilage degeneration-related genes.Combined with five algorithms in CytoHubba software,four key exosome-derived cartilage degeneration-related genes were further screened,namely THY1,CYP1A1,NFKB2,and COL6A3.(5)The results of qRT-PCR showed that compared with normal cartilage,the expressions of THY1 and COL6A3 in osteoarthritic cartilage were increased,while the expression of CYP1A1 and NFKB2 was decreased.Similarly,compared with the unstimulated group,the expression of THY1 and COL6A3 in the interleukin-1β induced chondrocytes was upregulated,while the expression of CYP1A1 and NFKB2 was downregulated.(6)These results indicate that THY1,CYP1A1,NFKB2,and COL6A3 are genes related to cartilage degeneration in the exosomes of synovial fluid of patients with osteoarthritis,and may participate in the pathogenesis of osteoarthritis by regulating biological processes such as protein tyrosine kinase activity and lipid metabolism,as well as nuclear factor-κB signaling pathway and focal adhesion signaling pathway.However,the specific regulatory roles and molecular mechanisms of these key genes in cartilage degeneration need to be further verified by experiments.

To summarize the nursing experience of a patient with acute injection botulism complicated with respiratory failure.The key nursing points include early standard use of botulinum antitoxin therapy to improve the signs of myasthenia;to strengthen respiratory support and airway management,to carry out respiratory training,and to promote the recovery of respiratory function;swallowing function training and dynamic evaluation were carried out to promote the recovery of swallowing function;narrative nursing was carried out to relieve patient's negative emotions.After 17 days of treatment and nursing care,the patient was removed from the tracheal tube on the 7th day,transferred to the general ward on the 14th day,and discharged successfully on the 17th day with a good prognosis.A telephone follow-up was conducted 4 months after discharge,and the patient recovered well.
