BackgroundThe prevalence of depressive disorder in adolescents is on the rise. There have been studies on the pairwise relations between dysfunctional attitude， negative automatic thoughts， positive coping style and depressive symptoms in the past. However， the impact of the intrinsic relations among dysfunctional attitude， negative automatic thoughts and positive coping style on depressive symptoms is still unclear. ObjectiveTo explore the influence of dysfunctional attitude on adolescent depressive symptoms and examine the action path of negative automatic thoughts and positive coping style on it， in order to provide references for intervention for adolescent patients with depressisve disorder. MethodsThis study involved 162 adolescent patients with depressive disorder， who met the diagnostic criteria for depressive episodes in the International Classification of Diseases， 10th edition （ICD-10） and received treatment in Taiyuan Psychiatric Hospital from October 1， 2022 to October 31， 2023. These patients were evaluated using Self-rating Depression Scale （SDS）， Dysfunction Attitude Scale （DAS）， Positive Coping Style Subscale in Simplified Coping Style Questionnaire（SCSQ） and Automatic Thoughts Questionnaire （ATQ）. Pearson correlation analysis was adopted to examine the correlation among scores of scales above. Model 6 in Process 3.4.1 was adopted to test the acting path of negative automatic thoughts and positive coping style between dysfunctional attitude and adolescent depression symptoms. ResultsA total of 148 adolescent patients with depressive disorder completed an effective questionnaire survey， with a response rate of 91.36%. The direct effect value of dysfunctional attitude on depressive symptoms was 0.423 and the effect size was 63.32%. Negative automatic thoughts and positive coping style affected as acting path between dysfunctional attitude and depressive symptoms， with effect values of 0.156 （accounting for 23.35% of the total effect） and 0.045 （accounting for 6.74% of the total effect） respectively. Meanwhile， negative automatic thoughts and positive coping style affected as a chain reaction pathway between dysfunctional attitude and depressive symptoms， with an effect value of 0.044， accounting for 6.59% of the total effect. ConclusionDysfunctional attitude can not only directly affect the depressive symptoms of adolescent patients with depressive disorder， but also affect the depressive symptoms of adolescent patients with depressive disorder through the independent path or chain path of negative automatic thoughts and positive coping style.

Objective:To explore the causal relationship between social activity and depressive symptoms in the elderly, and to provide a reference for preventing and interventing depressive symptoms in the elderly.Methods:Data were sourced from the China Health and Retirement Longitudinal Study (CHARLS) program, involving 3 164 elderly individuals aged≥60 years with data collected in two measurements, in 2015 (T1) and 2018 (T2). The sample included 1 240 males and 1 924 females aged (71±7) years. Social activities were assessed by constructing a social activity index from the 11 social activities included in the CHARLS questionnaire and the frequency of their activities. The depressive symptoms were assessed using the short version of the Center for Epidemiological Studies Depression Scale (the 10-item Center for Epidemiological Studies Depression Scale, CESD-10). A mixed-design ANOVA was used to explore the trends in social activity and depressive symptoms over time and across genders in the elderly adults. Pearson correlation analysis was used to investigate whether social activity and depressive symptoms in the elderly met the criteria for simultaneous and sequential correlations, followed by a cross-lagged model to analyze the causal temporal or mutual prediction between social activeness and depressive symptoms over a 3-year intervals.Results:The social activity of elderly men at T2 was significantly lower than at T1 ( F=21.00, P<0.001), while no significant difference observed in elderly women ( F=0.31, P<0.001). At both T1 and T2, elderly men scored higher in social activity than elderly women [T1: 2.93±2.98 vs 2.55±2.65,T2: 2.28±2.49 vs 2.24±2.43); F=43.60, 11.24, both P<0.01]. Depressive symptoms at T2 were higher than at T1 for both elderly men and elderly women ((male: 1.90±6.10 vs 21.52±6.08, female: 23.84±6.54 vs 23.07±6.44); F=5.20, 32.77, both P<0.05). Elderly men scored lower than elderly women on depression symptoms at both T1 and T2 (T1: F=45.74, P<0.001; T2: F=69.96, P<0.001). Pearson correlation analysis showed a negative correlation between social activity and depressive symptoms at both measurement points (T1: r=-0.329, P<0.01; T2: r=-0.343, P<0.01), and a positive correlation across T1 and T2 ( r=0.391, 0.573; both P<0.01), meeting the criteria for simultaneous and sequential correlations, and supporting the basic assumptions of cross-lagged design. Cross-lagged analysis revealed that T1 social activity negatively predicted T2 depressive symptoms (β=-0.128, P<0.001), and T1 depressive symptoms negatively predicted T2 social activity (β=-0.202, P<0.001). Conclusion:There is a bidirectional predictive relationship between social activity and depression symptoms in the elderly. Depression symptoms lead to a decrease in social activity, and a decrease in social activity predicts an exacerbation of depression in the elderly.

Objective:To investigate the safety and prognosis of partial nephrectomy (PN) in the treatment of highly malignant non-clear renal cell carcinoma (nccRCC).Methods:Clinical data of 47 patients with cT 1N 0M 0 high malignant nccRCC treated in Changhai Hospital from March 2016 to March 2022 were retrospectively analyzed. All patients received PN. There were 34(72.3%) males and 13(27.7%) females. The mean age was (53.5±15.0) years, and average BMI, was(23.7±3.4)kg/m 2.The maximum tumor diameter was (29.8±12.6) mm, and R. E.N.A.L. score was 7(5-9), with 37(78.7%) cases of T 1a and 10(21.3%) cases of T 1b. The mean estimated glomerular filtration rate (eGFR) before surgery was (96.3±25.5) ml/ (min·1.73m 2). All patients underwent PN, including 1 patient (2.1%) undergoing open surgery, 29 patients (61.7%) undergoing laparoscopic surgery, and 17 patients (36.2%) undergoing robotic surgery. There were a total of 22(46.8%) cases of papillary cell carcinoma(pRCC)type Ⅱ, 4(8.5%) cases of collecting duct carcinoma (cdRCC), 9(19.1%) cases of MiT family translocated renal cell carcinoma (tRCC), 5(10.6%) cases of mucoid tubular and spindle cell carcinoma (mtSCC)and 7(14.9%) cases of unclassified renal cell carcinoma (uRCC). The surgical conversion rate, positive margin rate, operative time, intraoperative blood loss, complications, and postoperative hospital stay were analyzed. Preoperative and postoperative eGFR were analyzed, and overall survival (OS) and cancer specific survival (CSS) were calculated. Results:All the operations were successfully completed. No radical operation or open operation was performed, with operation time of(100±60) min and intraoperative blood loss of(100±59) ml. There were no intraoperative complication and 1 case (2.1%) suffered from postoperative complication. Postoperative hospital stay were 5 (4-6) days. The mean eGFR after surgery was (86.5±27.1) ml/(min·1.73m 2), and the difference was statistically significant ( P=0.041). In this study, the mean follow-up time was (45.7±20.9)months, and no adjuvant therapy was used after surgery. During the follow-up period, 2 patients died, who all of them were kidney cancer-related death, and both OS and CSS were 95.7% (45/47). Conclusions:PN is safe, feasible and has a good prognosis in the treatment of high malignant T 1 nccRCC. For tumors with clear imaging boundaries and complete envelope, complete tumor resection is more likely, postoperative follow-up should be strict, and no remedial radical or systemic treatment was required.

Objective To develop a non-contact identification method for gait asymmetry in Parkinson's disease based on depth image to assist medical diagnosis and assessment, to avoid the cost, impact on normal life, and complex process of high wear-out sensing equipment. Methods From July to August, 2016, eight patients with Parkinson's disease and ten healthy subjects were collected the gait parameters of walking six meters with Kinect V2.0. The parameters of left and right foot were filtered and clustered. Then similarity matrix algorithm was used to find the difference between healthy subject and patient similarity values. Finally, the recognition effect of this method was verified by Hidden Markov Model. Results The similarity of clustering sequences of left and right foot parameters was less in the patients than in the healthy individuals. There were twelve of 14 data identified in patients, and 35 of 46 in the healthy. Conclusion A non-contact identification method for the asymmetry of gait has been developed based on the parameter clustering results of left and right foot, which is some effective on identifying Parkinson's patients.
