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.

AIM:To investigated the mechanism of action of Yiqi tongfu xiere prescription(YTX)in treating mice with lipopolysaccharide(LPS)-in-duced acute lung injury(ALI).METHODS:According to the random number table,24 C57BL/6 mice were divided into 4 groups:control group(Control),model group(LPS),low dose group(YTX-L)and high dose group(YTX-H).Except for the control group,the mice models of acute lung injury were established by intratracheal instillation of LPS solu-tion(5 mg/kg).The low and high dose treatment groups were given intragastric administration con-tinuously for 14 days.After 24 hours,the lung tis-sue,bronchoalveolar lavage fluid(BALF)and serum of the four groups were taken for follow-up detec-tion.The degree of pulmonary edema was evaluat-ed by wet weight coefficient(wet to dry ratio,W/D)of lung tissue.The degree of alveolar inflamma-tion and pulmonary fibrosis were evaluated by HE and Masson staining,and the contents of BALF and serum inflammatory cytokines IL-1β and IL-6 were detected by ELISA.The protein expressions of α-SMA,FN,Col-Ⅰ and Col-Ⅲ were measured by West-ern blot.Determination of α-SMA,FN,Col-Ⅰ,MAPK,NF-κB mRNA expression by RT-PCR method.RE-SULTS:Compared with LPS group,the contents of BALF,IL-1β and IL-6 in serum,Wmax D ratio,lung pathology,serum α-SMA,FN,Col-Ⅰ,Col-Ⅲ protein expression and α-SMA,FN,Col-Ⅰ,MAPK,NF-κB mRNA expression in treatment group were signifi-cantly lower than those in control group.CONCLU-SION:YTX can significantly reduce the levels of pul-monary fibrosis markers such as α-SMA,FN,Col-Ⅰand Col-Ⅲ by inhibiting the activation of MAPK/NF-κB signal pathway,and improve alveolar inflamma-tion and pulmonary fibrosis in mice with lung inju-ry,suggesting that YTX can treat acute lung injury and provide a theoretical basis for the clinical use of YTX.

Objective To investigate the appropriate indicators for monitoring pediatric nociceptive stimu-lation,this study compared the SPI and NOX,two dual-parameter nociceptive stimulation monitors based on different principles,in terms of their effects on remifentanil consumption and postoperative recovery in pediatric adenotonsil-lectomy.Methods Children aged 3～12 years who were scheduled to undergo adenotonsillectomy under general anesthesia with endotracheal intubation were randomly assigned to the conventional group(Group R,n=19),the SPI group(Group S,n=19),and the NOX group(Group N,n=18)according to the type of nociceptive stimu-lation monitor used.All children were subjected to routine fasting.The depth of anesthesia was monitored using a BIS monitor,and the remifentanil infusion rate was adjusted according to heart rate,SPI,or NOX values to maintain the index within the range of 30～50.After surgery,all children were transferred to the Post-Anesthesia Care Unit(PACU)with the tracheal catheter in place until they recovered.During the operation,the consumption of anes-thetics such as remifentanil was recorded.Postoperatively,pain and agitation scores,the incidence of agitation at different time points,the duration of anesthesia,the surgical time,the time to extubation,and the length of stay in the recovery room were measured.Additionally,postoperative adverse reactions and perioperative vital signs were documented.Results In comparison with Group R,in Group N,the intraoperative consumption of remifentanil and the agitation score during the recovery period were significantly reduced.Conversely,in Group S,both of(P<0.05).There were no significant disparities in the FLACC score,the incidence of agitation,and the extubation time among the three groups.Conclusions The NOX index can serve as a quantitative metric for monitoring nonci-ceptive stimulation during pediatric adenotonsillectomy.This index has the potential to decrease the intraoperative consumption of opioids and the residence time in the recovery room.

Objective To investigate whether resveratrol alleviates hyperglycemia-induced cardiomyocyte hypertrophy by enhancing the expression of silent information regulation 2 homolog 1(SIRT1)to maintain mitochondrial homeostasis.Methods Rat cardiomyocytes H9c2 cells with or without lentivirus-mediated mRNA interference of SIRT1 were cultured in high glucose(HG)and treated with resveratrol for 72 h.The changes in superoxide dismutase(SOD)activity,malondialdehyde(MDA)content,reactive oxygen species(ROS)level,and relative surface of the cells were examined,and the mRNA expressions of atrial natriuretic factor(ANF)and brain natriuretic peptide(BNP)and protein expressions of SIRT1,mitochondrial fusion related proteins optic atrophy protein 1(OPA1)and mitofusin 2,mitochondrial division related proteins dynamin-related protein 1(DRP1)and fission protein 1(FIS1),and mitophagy-related proteins BNIP3L and LC3 were detected using RT-qPCR and Western blotting.Results HG exposure significantly decreased SOD activity,increased MDA content,ROS production,relative cell surface,and the mRNA expressions of ANF and BNP in the cardiomyocytes;the protein expressions of SIRT1,OPA1,mitofusin 2 and BNIP3L and LC3-Ⅱ/LC3-Ⅰ ratio were all decreased and the protein expressions of DRP1 and FIS1 increased in HG-exposed cells(P<0.01).All these changes in HG-exposed cardiomyocytes were significantly alleviated by treatment with resveratrol(P<0.05).The protective effects of resveratrol against HG exposure in the cardiomyocytes were obviously attenuated by transfection of the cells with si-SIRT1(P<0.05).Conclusion Resveratrol inhibits hyperglycemia-induced cardiomyocyte hypertrophy by reducing oxidative stress,the mechanisms of which involve enhancement of SIRT1 protein expression,regulation of mitochondrial fusion and division balance,and promoting BNIP3L-mediated mitophagy to maintain mitochondrial homeostasis in the cells.

ObjectiveTo investigate the effect and mechanism of Yiqi Wenyang Huwei decoction （YWHD） on airway inflammation in bronchial asthma （BA） rats based on transforming growth factor-β₁ （TGF-β₁）/SMAD family member 3 （Smad3） signaling pathway. MethodSixty male SD rats were randomly divided into a normal group， a model group， a dexamethasone （DEX） group， and low-， medium-， and high-dose YWHD groups， with 10 rats in each group. The BA model was induced by intraperitoneal injection of 1 mL of ovalbumin （OVA）-aluminum hydroxide suspension for sensitization， followed by nebulization with 2% OVA. One hour before daily OVA nebulization， the control group was treated with saline， the DEX group with DEX solution at 0.2 g·L^-1， and the low-， medium-， and high-dose YWHD groups with YWHD at 1， 2， 4 g·mL^-1， respectively. General conditions and lung function were observed. Bronchoalveolar lavage fluid （BALF） and serum were collected to count inflammatory cells in BALF and measure immunoglobulin E （IgE） levels in serum and inflammatory cytokines in BALF using enzyme-linked immunosorbent assay （ELISA）. Pathological changes in lung tissues， collagen deposition， and airway mucus secretion were observed by hematoxylin-eosin （HE）， Masson， and periodic acid-Schiff （PAS） staining. TGF-β₁/Smad3-related mRNA and protein levels in lung tissues were determined by Real-time fluorescent quantitative polymerase chain translation （Real-time PCR） and Western blot analysis. ResultCompared with the normal group， the model group showed increased total airway resistance （RL） and decreased dynamic compliance （Cdyn） （P<0.05， P<0.01）， elevated serum IgE levels， increased inflammatory cell counts， and higher inflammatory cytokine levels in BALF （P<0.01）. Additionally， there was significant inflammatory cell infiltration， collagen deposition， and mucus secretion in lung tissues. The levels of TGF-β₁， α-smooth muscle actin （α-SMA）， and Smad3 phosphorylation in lung tissues were significantly increased （P<0.01）. Compared with the model group， the DEX group and high-dose YWHD group exhibited significantly reduced RL （P<0.01）， improved lung dynamic compliance （P<0.05）， and lower serum IgE levels， inflammatory cell counts， and inflammatory cytokine levels in BALF （P<0.05）. Moreover， these treatments alleviated pathological damage in lung tissues and reduced the levels of TGF-β₁， α-SMA， and Smad3 phosphorylation （P<0.01）. ConclusionYWHD reduces airway inflammation， improves pathological damage， and mitigates airway remodeling in bronchial asthma rats， possibly by downregulating TGF-β₁， α-SMA protein levels， and Smad3 phosphorylation.
