BackgroundCurrently， the incidence of depression among teenagers is on the rise， and the related academic problems are becoming increasingly serious. Short video addiction has a negative impact on teenagers' emotional issues and academic achievements. However， few studies have explored the relationship between this addiction and the learning burnout of teenagers with depression， and even fewer have focused on the role paths of impulsivity and coping disposition in this process. ObjectiveTo explore the relationship between short video addiction and learning burnout in adolescent patients with depression， as well as the pathway of impulsivity and coping disposition， so as to provide references for the intervention of learning burnout in adolescent patients with depression. MethodsA total of 191 adolescent patients who were hospitalized at The Affiliated Brain Hospital of Guangzhou Medical University from December 2024 to April 2025 and met the diagnostic criteria for depression according to the International Classification of Diseases， tenth edition （ICD-10） were selected consecutively. The Short Video Addiction Measurement Scale （SVAMS）， the Brief Barratt Impulsiveness Scale （BBIS）， the Simplified Coping Style Questionnaire （SCSQ）， and the Adolescent Student Burnout Inventory （ASBI） were used for assessment. Pearson correlation analysis was employed to examine the correlations of the scores of each scale. Model 6 of the SPSS macro Process 4.2 was employed to analyze the chained mediation pathway of impulsivity and coping disposition between short video addiction and learning burnout. ResultsA total of 173 cases （90.58%） of adolescent patients with depression completed the valid questionnaire survey. Correlation analysis showed that SCSQ coping disposition score was negatively correlated with the SVAMS score， the BBIS score， and the ASBI score （r=-0.282， -0.341， -0.431， P<0.01）， the SVAMS score was positively correlated with the BBIS score and the ASBI score （r=0.339， 0.262， P<0.01）， and the BBIS score was positively correlated with the ASBI score （r=0.486， P<0.01）. The pathway analysis showed that the direct effect of short video addiction on learning burnout was not statistically significant， but the total effect and the indirect effect were statistically significant. The effect values were 0.275 （95% CI： 0.207–0.343） and 0.193 （95% CI： 0.143–0.246）， respectively， with the indirect effect accounting for 70.18%. Impulsivity and coping disposition both played independent mediating roles between short video addiction and learning burnout， with effect values of 0.122 （95% CI： 0.090–0.156） and 0.054 （95% CI： 0.032–0.079）， accounting for 44.36% and 19.64% of the total effect， respectively. The chained mediation effect of impulsivity and coping disposition was significant， with an effect value of 0.017 （95% CI： 0.011–0.026）， accounting for 6.18% of the total effect. ConclusionAlthough short video addiction does not directly affect learning burnout in adolescent patients with depression， it may indirectly influence learning burnout through independent and chain paths of impulsivity and coping disposition. ［Funded by Guangzhou Key Clinical Specialty （Clinical Medical Research Institute）］

Objective:To investigate the clinical outcomes of arthroscopic suture anchor fixation for acute bony Bankart lesions.Methods:Data of 49 patients with acute bone Bankart injury treated with suture anchor fixation under arthroscopy at the Affiliate Nanjing Drum Tower Hospital of Nanjing University School of Medicine from February 2019 to July 2024 were retrospectively analyzed, including 34 males and 15 females, aged 46.4±17.7 years (range, 18-81 years). Body mass index was 26.3±4.2 kg/m 2 (range, 19.8-37.9 kg/m 2). There were 17 patients with left shoulder and 32 patients with right shoulder. The time from injury to operation was 12.6±10.5 d (range, 1-50 d). CT three-dimensional reconstruction showed that the area of bone defect accounted for 20.1%±11.4% (range, 8%-49%) of the glenoid area. According to the degree of bone defect, there were 38 cases in the bone defect area ≤25% group and 11 cases in the bone defect area >25% group. All 49 patients received shoulder arthroscopic fixation with wire anchor. All 49 the patients were treated under shoulder arthroscopy using suture anchor technique. Using American Shoulder & Elbow Surgeon (ASES) score, University of California, Los Angeles (UCLA) score, Rowe score as well as shoulder range of motion to evaluate shoulder function. The position and healing of the fracture mass were evaluated with shoulder joint CT and three-dimensional reconstruction at immediate and final follow-up. Results:The incision healed in one stage and no infection occurred in all patients. All 49 patients were followed up for a period of 3 to 81 months, with an average follow-up of 23.8±20.2 months. At the final follow-up, the mean forward elevation, external rotation, and internal rotation improved from 126.1°±20.3°, 36.9°±14.0°, and 10±2 preoperatively to 167.1°±15.5°, 66.8°±8.3°, and 6±1 at the last follow-up, respectively ( P<0.05). At the final follow-up, the mean ASES score, UCLA score, and Rowe score were all significantly improved from 41.3±11.9, 14.2±6.1 and 46.9±14.7 preoperatively to 89.7±7.8, 31.5±3.6 and 92.4±7.4, respectively ( P<0.05). The differences between the final follow-up and preoperative values for forward elevation in the bone defect area >25% group and the bone defect area ≤25% group were 43°±20° and 41°±21°, respectively. The differences in lateral external rotation were 34°±8° and 29°±18°, while the differences in internal rotation (measured by hand-behind-back reach) were 5±2 and 4±2, respectively. None of these differences were statistically significant. The differences between the final follow-up and preoperative scores in the bone defect area >25% fracture fragment group and the bone defect area ≤25% group were as follows: ASES score, 50.9±14.4 vs. 47.7±12.8; UCLA score, 18.4±3.2 vs. 17.0±6.9; and Rowe score, 40.5±13.5 vs. 46.9±15.0. None of these differences were statistically significant. CT examination at the last follow-up showed that all fractures were healed, all patients in the bone defect area ≤25% group achieved good reduction, and 3 patients in the bone defect area >25% group had step-offs on the glenoid surface. Postoperative shoulder adhesion occurred in 5 patients, which was improved after intensive abduction and external rotation exercise. Conclusions:Arthroscopic suture anchor fixation is effective for the bone defect area ≤25% bony Bankart lesions, offering advantages of minimal invasiveness and rapid recovery. For lesions involving more than the bone defect area 25% of the glenoid surface, enhanced fixation strength is recommended to prevent fracture fragment displacement.

Osteoarthritis (OA), the most prevalent joint disease of late life, is closely linked to cellular senescence. Previously, we found that the senescence of fibroblast-like synoviocytes (FLS) played an essential role in the degradation of cartilage. In this work, single-cell sequencing data further demonstrated that cartilage acidic protein 1 (CRTAC1) is a critical secreted factor of senescent FLS, which suppresses mitophagy and induces mitochondrial dysfunction by regulating SIRT3 expression. In vivo, deletion of SIRT3 in chondrocytes accelerated cartilage degradation and aggravated the progression of OA. Oppositely, intra-articular injection of adeno-associated virus expressing SIRT3 effectively alleviated OA progression in mice. Mechanistically, we demonstrated that elevated CRTAC1 could bind with NRF2 in chondrocytes, which subsequently suppresses the transcription of SIRT3 in vitro. In addition, SIRT3 reduction could promote the acetylation of FOXO3a and result in mitochondrial dysfunction, which finally contributes to the degradation of chondrocytes. To conclude, this work revealed the critical role and underlying mechanism of senescent FLSs-derived CRTAC1 in OA progression, which provided a potential strategy for the OA therapy.

Objective:To explore the relevant risk factors for deep venous thrombosis (DVT) of lower limb occurring 3 months after joint replacement surgery.Methods:A retrospective analysis was conducted on the clinical data of 1,782 patients who underwent joint replacement surgery at Drum Tower Hospital, School of Medicine of Nanjing University, from February 2015 to December 2018. Of these, 1,298 were male and 484 were female, with an average age of 65.4±12.3 years (range, 18-95 years). Fourteen factors associated with DVT occurrence at 3 months were investigated, including age, gender, body mass index (BMI), season of surgery, preoperative coagulation function, type of surgery, selection of minimally invasive approach, occurrence of lower limb venous thrombosis 1 day after surgery, history of previous thrombotic diseases, smoking, tumors, diabetes, hypertension, and heart disease. Independent sample t-tests and chi-square tests were used to analyze the risk factors for DVT occurrence. Indicators with statistically significant differences were included in a binary logistic regression analysis to determine the risk factors for DVT 3 months after surgery. The risk prediction model was established according to the results of logistic regression analysis, and the receiver operating characteristic curve was drawn. The area under the curve of the prediction model was calculated. Results:A total of 1,782 patients were included. The overall incidence of DVT occurring 3 months after joint replacement surgery was 10.5% (187/1,782). The thrombosis group included 5 symptomatic cases and 182 asymptomatic cases, with 13 proximal and 174 distal cases. DVT was found in the iliac vein (1 case), femoral vein (10 cases), popliteal vein (8 cases), peroneal vein (14 cases), and intramuscular vein (168 cases). Single-factor analysis showed that female gender, increasing age, previous thrombotic disease, hypertension, surgery in autumn, and the occurrence of DVT on the first day after surgery were correlated with DVT occurring 3 months after joint replacement surgery ( P<0.05). After excluding the missing data, a total of 1,744 patients were included in the final analysis. DVT occurrence on the first day after surgery [ OR=7.498, 95% CI (5.312, 10.584), P<0.001], surgery in autumn [ OR=1.834, 95% CI (1.215, 2.769), P=0.004], age [ OR=1.024, 95% CI (1.007, 1.042), P=0.009], female gender [ OR=1.863, 95% CI(1.184, 2.931), P=0.007], and history of previous thrombotic diseases [ OR=0.012, 95% CI (1.136, 2.830), P=0.012] were found to be associated with DVT occurrence at 3 months after surgery. The area under the curve (AUC) for predicting DVT three months after hip or knee arthroplasty was 0.803 [95% CI (0.761, 0.844)]. Conclusion:Advanced age, female gender, history of previous thrombotic diseases, occurrence of DVT on the first day after surgery, and surgery in autumn are risk factors for DVT occurring 3 months after joint replacement surgery.

Objective To explore whether hepatocyte Perilipin-2(Plin2)is involved in the development of fatty liver related to comparative gene identification-58(CGI-58)deficiency mice and compare the effects of Plin2 and Plin3 on lipid droplet formation and lipid accumulation.Methods Based on CGI-58Flox/Flox mice as animal model,the adeno-associated viruses targeting mouse liver,CGI-58 knockout and Plini2 knockdown were achieved by co-expression Cre protein and micro-RNA targeting Plin2(Mi-KD).Then CGI-58 deficiency mice were used as control(NC)to detect the differences in metabolic phenotype and liver pathology.AML-12 mouse hepatocytes were used as cellular model and interfered with siRNA to achieve Plin2/Plin3 knockdown in AML-12 cells.Lipid droplet formation and lipid accumulation were compared with Bodipy staining and enzyme colorimetry in basal condition or lipid-overloaded condition(OA inducement)after Plin2/Plin3 knockdown.Results Plin2 knockdown(Mi-KD)reduced PLIN2 protein level by＞99％in mouse livers.Mi-KD decreased hepatomegaly(P=0.019 5)and liver injury(P=0.000 4),while reduced the histological NAS score(P=0.000 2)and hepatic triglyceride content(P=0.016 6)in the CGI-58 deficiency female mice.Mi-KD prevented microvesicular hepatic steatosis in the CGI-58 deficient female mice.Plin3 knockdown significantly reduced the triglyceride content in basal condition of hepatocytes(P=0.001 4),and Plin2 knockdown just showed a decreased trend.Plin2 or Plin3 knockdown significantly reduced the triglyceride content separately in lipid-overloaded hepatocytes(P＜0.05).Conclusion Hepatocyte Plin2 is essential in the development of microvesicular hepatic steatosis caused by CGI-58 deficiency.Both Plin2 and Plin3 are involved in lipid droplet formation and lipid accumulation in hepatocytes,and Plin3 shows a stronger effect.

OBJECTIVE: To investigate the feasibility and effectiveness of "tail compression fixation+suture bridge" technology under shoulder arthroscopy for treating primary tear in medial enthesis of rotator cuff. METHODS: The clinical data of 11 patients with primary tear in medial enthesis of rotator cuff who met the selection criteria between October 2020 and October 2022 were retrospectively analyzed, including 3 males and 8 females, aged 39-79 years, with an average of 61.0 years. Rotator cuff injury was caused by traumatic fall in 8 cases, and the time from injury to admission was 1-4 months, with an average of 2.0 months; the remaining 3 cases had no obvious inducement. The active range of motion of the affected shoulder was limited, with an active forward flexion range of motion of (64.1±10.9)°, abduction of (78.1±6.4)°, internal rotation of (48.2±6.6)°, and external rotation of (41.8±10.5)°; 5 cases had shoulder stiffness. The preoperative visual analogue scale (VAS) score was 7.8±0.8 and the American Society of Shoulder and Elbow Surgeons (ASES) score was 23.9±6.4. The patients were treated with "tail compression fixation+suture bridge" technology under shoulder arthroscopy, and the pain and functional recovery were evaluated by VAS score, ASES score, and active range of motion of shoulder joint at last follow-up; MRI was performed after operation, and the integrity of rotator cuff was evaluated by Sugaya classification system. RESULTS: All the 11 patients were followed up 2-22 months, with an average of 13.5 months. All incisions healed by first intention, and there was no complication such as infection, rotator cuff re-tear, and anchor falling off. At last follow-up, the VAS score was 0.8±0.7 and the ASES score was 93.5±4.2, which significantly improved when compared with those before operation ( P<0.05). All 11 patients had no significant swelling in the shoulders, and the active range of motion was (165.1±8.8)° in flexion, (75.3±8.4)° in abduction, (56.6±5.5)° in internal rotation, and (51.8±4.0)° in external rotation, which significantly improved when compared with those before operation ( P<0.05). Shoulder MRI showed adequate tendon thickness and good continuity in 9 cases, including 4 cases with partial high signal area; and 2 cases with inadequate tendon thickness but high continuity and partial high signal area. According to Sugaya classification system, there were 4 cases of type 1 (36.4%), 5 cases of type 2 (45.5%), and 2 cases of type 3 (18.1%). CONCLUSION For the patients with primary tear in medial enthesis of rotator cuff, the "tail compression fixation+suture bridge" technology under shoulder arthroscopy is simple and effective.

Objective    To explore the application value of machine learning models in predicting postoperative survival of patients with thoracic squamous esophageal cancer. Methods    The clinical data of 369 patients with thoracic esophageal squamous carcinoma who underwent radical esophageal cancer surgery at the Department of Thoracic Surgery of Northern Jiangsu People's Hospital from January 2014 to September 2015 were retrospectively analyzed. There were 279 (75.6%) males and 90 (24.4%) females aged 41-78 years. The patients were randomly divided into a training set (259 patients) and a test set (110 patients) with a ratio of 7 : 3. Variable screening was performed by selecting the best subset of features. Six machine learning models were constructed on this basis and validated in an independent test set. The  performance of the models' predictions was evaluated by area under the curve (AUC), accuracy and logarithmic loss, and the fit of the models was reflected by calibration curves. The best model was selected as the final model. Risk stratification was performed using X-tile, and survival analysis was performed using the Kaplan-Meier method with log-rank test. Results    The 5-year postoperative survival rate of the patients was 67.5%. All clinicopathological characteristics of patients between the two groups in the training and test sets were not statistically different (P>0.05). A total of seven variables, including hypertension, history of smoking, history of alcohol consumption, degree of tissue differentiation, pN stage, vascular invasion and nerve invasion, were included for modelling. The AUC values for each model in the independent test set were: decision tree (AUC=0.796), support vector machine (AUC=0.829), random forest (AUC=0.831), logistic regression (AUC=0.838), gradient boosting machine (AUC=0.846), and XGBoost (AUC=0.853). The XGBoost model was finally selected as the best model, and risk stratification was performed on the training and test sets. Patients in the training and test sets were divided into a low risk group, an intermediate risk group and a high risk group, respectively. In both data sets, the differences in surgical prognosis among three groups were statistically significant (P<0.001). Conclusion    Machine learning models have high value in predicting postoperative prognosis of thoracic squamous esophageal cancer. The XGBoost model outperforms common machine learning methods in predicting 5-year survival of patients with thoracic squamous esophageal cancer, and it has high utility and reliability.

OBJECTIVE：To prov ide referen ce for clinical safe and rational use of belimumab by mining the risk signals of adverse drug event （ADE）. METHODS ：ADE reports related to belimumab were collected from FDA adverse event reporting system（FAERS）from the first quarter of 2015 to the first quarter of 2021. The reporting odds ratio （ROR）method and the Medicines and Healthcare Products Regulatory Agency （MHRA）method were adopted to mine the ADE risk signals related to belimumab，setting the threshold as the number of reports ＞3 and the lower limit of 95％ CI ＞1（ROR method ）and the proportional reporting ratio （PRR）＞2，and χ2 ＞4（MHRA method ）. ADEs were counted and classified by using the preferred system organ class （SOC）and preferred term （PT）of Medical Dictionary for Regulatory Activities （MedDRA）. RESULTS & CONCLUSIONS：A total of 3 529 ADE reports with belimumab as the primary suspicious drug were screened ，in which female patients（90.31％）were much more than male patients （6.15％）；age distribution was concentrated in 18-59 years old （41.80％）. There were 1 234 cases（34.97％）of severe ADE reports ，mainly involving hospital or prolonged hospital stay. Most of the reporters were consumers or other non-medical professionals （81.84％）. North America reported the most （70.39％）and the main reporting country was the United States （2 029 reports）. A total of 180 PTs were mined from 3 529 reports，in addition to PTs associated with primary disease （systemic lupus erythematosus ，pain，arthralgia，pyrexia，weight decreased ，swelling，oropharyngeal pain ， etc.），PTs related to medication error （product dose omission ，inappropriate schedule of product administration ，underdose， product availability issue ，etc.）and PTs related to infection （influenza，urinary tract infection ，infection，sinusitis，etc.）were reported in a large number of cases. Twenty-six SOCs were involved ，the top 10 SOC in ADE reports were all kinds of injuries ， poisoning and surgical complications （2 225 reports），infections and infectious diseases （1 247 reports），general disorders and administration site conditions （1 196 reports），musculoskeletal and connective tissue disorders （1 195 reports），surgical and medical procedures（515 reports），etc. PTs in SOC in the first place （all kinds of injuries ，poisoning and surgical complications ）of ADE reports were all related to medication error ；herpes zoster ，kidney infection and cellulitis in SOC in the second place （infections and infectious diseases ）of ADE reports were not included in the drug instruction of belimumab ；most PTs in SOCs such as various nervous system diseases ，immune system diseases ，mental diseases ，benign，malignant and unknown tumors （including cystic and polypoid）which were taken attention in clinic were not included in the drug instruction of belimumab. It is suggested to avoid medication errors as far as possible in clinical use of belimumab ，and to guard against adverse reactions such as herpes zoster ， kidney infection ，cellulitis and various nervous system diseases ，immune system diseases and mental diseases. In addition ，the patients with malignant tumor or related history should use belizumab carefully.
