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.

Purpose: This study assessed the performance of the ultrasound-guided attenuation parameter (UGAP) in diagnosing and grading hepatic steatosis in patients with metabolic dysfunctionassociated steatotic liver disease (MASLD). Magnetic resonance imaging proton density fat fraction (MRI-PDFF) served as the reference standard. Methods: Patients with hepatic steatosis were enrolled in this prospective study and underwent UGAP measurements. MRI-PDFF values of ≥5%, ≥15%, and ≥25% were used as references for the diagnosis of steatosis grades ≥S1, ≥S2, and S3, respectively. Spearman correlation coefficients and area under the receiver operating characteristic curves (AUCs) were calculated. Results: Between July 2023 and June 2024, the study included 88 patients (median age, 40 years; interquartile range [IQR], 36 to 46 years), of whom 54.5% (48/88) were men and 45.5% (40/88) were women. Steatosis grades exhibited the following distribution: 22.7% (20/88) had S0, 50.0% (44/88) had S1, 21.6% (19/88) had S2, and 5.7% (5/88) had S3. The success rate for UGAP measurements was 100%. The median UGAP value was 0.74 dB/cm/MHz (IQR, 0.65 to 0.82 dB/ cm/MHz), and UGAP values were positively correlated with MRI-PDFF (r=0.77, P<0.001). The AUCs of UGAP for the diagnoses of ≥S1, ≥S2, and S3 steatosis were 0.91, 0.90, and 0.88, respectively. In the subgroup analysis, 98.4% (60/61) of patients had valid controlled attenuation parameter (CAP) values. UGAP measurements were positively correlated with CAP values (r=0.65, P<0.001). Conclusion Using MRI-PDFF as the reference standard, UGAP demonstrates good diagnostic performance in the detection and grading of hepatic steatosis in patients with MASLD.

Objective To quantitatively assess the correlation between the skeletal muscle index(SMI)of patients and the occur-rence of anastomotic leakage(AL)in rectal cancer patients after surgery,and to analyze the risk factors for AL in rectal cancer patients and the influencing factors of sarcopenia.Methods The clinical,pathological,and related imaging data of 362 patients who under-went radical surgery for rectal cancer were retrospectively analyzed.All patients underwent pelvic MRI and abdominal CT scans(plain/enhanced)within one month before surgery,and the third lumbar vertebra skeletal muscle area(L3-SMA)was measured from the images.All patients were divided into AL group(56 cases)and control group(306 cases)based on the presence or absence of postoperative complications.The differences in clinical characteristics and imaging parameters between the two groups were analyzed.A logistic risk prediction model was established.Results Significant differences were observed between the two groups in sarcopenia,type of surgery,surgical approach,serum albumin level,operation duration,stoma type,and extramural vascular invasion(EMVI)(P＜0.05).These factors were incorporated in a multivariate logistic regression analysis model,the area under the curve(AUC)of receiver operating characteristic(ROC)curve of the model was 0.810[95％confidence interval(CI)0.743-0.876,P＜0.001],with a sensitivity of 0.865 and specificity of 0.669.Conclusion Sar-copenia is a significant risk factor for AL after rectal cancer surgery.It enhances the predictive efficacy for postoperative AL and serves as a basis for identifying high-risk populations for AL in clinical practice.

Objective To investigate the predictive performance of serum soluble CD40 ligand(sCD40L),interleukin-17(IL-17)and neutrophil extracellular traps(NETs)in combination for intracranial aneurysm rupture.Methods A total of 120 patients with intracranial aneurysms admitted from January 2022 to January 2025 were selected and divided into low-risk group and medium-high-risk group according to different rupture risks.After propensity score matching with 1:1 ratio and caliper matching(caliper=0.02),there were 60 patients in each group.The general data and serum levels of sCD40 L,IL-17 and NETs were compared between the two groups.Multivariate logistic regression analysis was used to analyze the risk factors of intracranial aneurysm rupture.The linear relationship between serum sCD40 L,IL-17,NETs and the risk of intracranial aneurysm rupture was analyzed by smoothing curve fitting.The receiver operating characteristic(ROC)curve,clinical impact curve(CIC)and clinical decision curve analysis(DCA)were used to evaluate the predictive performance of serum sCD40L,IL-17 and NETs for intracranial aneurysm rupture.Results The irregular shape of aneurysms,the proportion of the longest diameter of aneurysms≥7 mm and the levels of serum sCD40L,IL-17 and NETs in the low-risk group were lower than those in the medium-high-risk group(P<0.01).The shape of aneurysm,the longest diameter of aneurysm,sCD40L,IL-17 and NETs were the independent risk factors for intracranial aneurysm rupture(P<0.05).After adjusting for other covariates,serum sCD40L,IL-17 and NETs were positively correlated with the risk of intracranial aneurysm rupture(P<0.05).The ROC curve showed that the area under the curve of serum sCD40L,IL-17 and NETs in combination for predicting the risk of intracranial aneurysm rupture was the largest.The DCA and CIC showed that both the net benefit of the combined prediction model of serum sCD40L,IL-17 and NETs in predicting the risk of intracranial aneurysm rupture and the coincidence rate with the actual situation were relatively high.Conclusion The elevated levels of serum sCD40L,IL-17,and NETs in patients with intracranial aneurysms are associated with their rupture risk.The combination of the three indicators has a high predictive performance for the risk of intracranial aneurysm rupture.

Aim To investigate the effect of Huangqi injection(HI)and Huangqi oral solution(HO)on cisplatin-induced nephrotoxicity(CIN)based on un-targeted metabolomics technology and the underlying mechanisms.Methods Sprague Dawley(SD)rats were randomly divided into the blank group,cisplatin(CDDP)model group,HI treatment group,and HO treatment group,then the CIN model was built with low dose multiple intraperitoneal injections of CDDP.Pre-liminary evaluation of the renal protective efficacy of HI and HO was performed by measuring serum creatinine(Scr),blood urea nitrogen(BUN),and organ indi-ces.Further screening and identification of potential biomarkers(PBs)related to CIN and HI/HO pharma-cological effects were attained through metabolomics studies of renal tissues,and pathway enrichment analy-sis was conducted.Results HI and HO significantly restored the abnormal increase in renal function indica-tors and abnormal decrease in organ indices caused by CDDP,as well as significantly improved the abnormal renal metabolic profile induced by CDDP,indicating that both HI and HO had good alleviating effects on CIN.HI significantly reversed 47 out of 54 CIN related PBs,mainly involving metabolic pathways such as glycerophospholipid metabolism,tryptophan metabo-lism,pantothenate and CoA biosynthesis;HO signifi-cantly reversed 18 out of 54 CIN related PBs,mainly involving metabolic pathways such as taurine and hypo-taurine metabolism,ascorbate and aldarate metabo-lism,pentose and glucuronate interconversions.Con-clusions Both HI and HO have significant alleviating effects on CIN.In the short term,HI salleviating effect is superior to that of HO.Overall,the mechanisms by which both alleviate CIN are mainly related to regula-ting lipid metabolism,amino acid metabolism.

Objective To explore clinical effect of accessory scaphoid bone fusion in treating type Ⅱ painful accessory scaphoid bone.Methods A retrospective analysis was performed on 26 patients with type Ⅱ painful accessory navicular bone treated by accessory navicular bone fusion from January 2012 to June 2022,including 1 male and 25 females,aged from 18 to 70 years old with an average of(44.61±16.32)years old;10 patients with type Ⅱ A and 16 patients with type Ⅱ B;20 patients with simple fusion and 6 patients with fusion plus calcaneal translocation osteotomy.Changes of Meary angle,Pitch angle,an-teroposterior talar-first metatarsal angle(T1MA),talonavicular coverage angle(TCA),lateral talocalcaneal angle(LTCA)be-fore operation and 6 months after operation were observed and compared,and American Orthopedic Foot and Ankle Society(AOFAS)foot and ankle score and visual analogue scale(VAS)were used to explore clinical effect.Results All 26 patients were followed up for 7 to 24 months with an average of(10.72±3.94)months.Meary angle,Pitch angle,T1MA,TCA and LTCA were improved from(9.20±2.57)°,(16.45±3.57)°,(33.34±5.02)°,(22.42±5.86)°,(48.89±4.43)° before opertaion to(3.33±1.06)°,(22.33±4.56)°,(23.89±3.48)°,(11.83±2.67)°,(36.50±3.50)° at 6 months after operation,the difference were statistically significant(P＜0.01).Postoperative AOFAS foot and ankle score were(86.24±4.33)and(93.18±6.02)for type Ⅱ A and type Ⅱ B at 6 months,which were significantly improved compared with those for type Ⅱ A and type Ⅱ B before op-eration(67.34±6.55)and(65.12±9.51),and the difference was statistically significant(P＜0.01);20 patients got excellent re-sult,5 good and 1 poor.Preoperative VAS of type ⅡA(5.67±1.58)and type Ⅱ B(5.77±1.49)were improved to(2.13±1.01)and(1.43±0.68)at 6 months after operation,with statistical significance(P＜0.01).Conclusion Fusion of accessory navicular bone in patients with type Ⅱ painful accessory navicular bone combined with internal calcaneal osteotomy in patients with par-tial calcaneal valvaration could effectively correct flat foot deformity and relieve pain,and could be used as a clinical treatment for painful accessory navicular bone.

Objective To evaluate the transition rules of normal body mass index(BMI),overweight and metabolic syndrome(MetS)in patients with major depressive disorder(MDD).Methods Patients with MDD who had multiple admission records between Jan 2016 and Nov 2021 in Beijing Anding Hospital,Capital Medical University were included.Based on the overweight and metabolic syndrome status assessed at each admission,the patients were categorized into three states:normal BMI,overweight and metabolic syndrome.A multi-state Markov model was used to analyze the transition intensity and transition frequency between three states and the influence of covariates on transitions.Results A total of 892 records of 398 subjects were included,with a median age of 56 years old and 31.4% males.The median follow-up period was 40 months.The multi-state model showed that there were 494 transitions between the three states,of which 5.1% moved from normal BMI to overweight and 5.5% moved from overweight to MetS.The intensity of transition was the highest from overweight to MetS,9.52 times greater than overweight to normal BMI.After 48.53 months,MDD patients with normal BMI began to transition to MetS.For overweight MDD patients,the transition to MetS started after 8.77 months.MDD patients with normal BMI or overweight had 31.4% and 50.4% probabilities of developing Mets after 36 months.For MDD patients comorbid with MetS,the probability of staying at MetS was 51.2% after 36 months.Multivariate analysis showed that being unmarried was a risk factor against developing overweight in normal BMI MDD patients,while a higher level of education was a protective factor against developing MetS in overweight MDD patients.Conclusion MDD patients exhibited a higher intensity and risk of developing MetS,and it is not easy to reverse MetS,suggesting that BMI management and MetS intervention should be strengthened in MDD patients.
