Objective: To understand the current status of neglect among rural preschool children in Xi an under the multi child policy and the association with family characteristics, so as to provide a reference for preventing and reducing the occurrence of child neglect. Methods: A total of 7 052 parents of preschool children were selected using stratified cluster sampling across 9 suburban counties/districts in Xi an from March to April 2025. A questionnaire survey was administered using the Chinese Norm Scale for Neglect Assessment of Rural(Preschool) Children Aged 3-6. The t-test, Chi-quare test, and analysis of variance (ANOVA) were used for inter group comparisons. Results: The overall prevalence rate and mean score of neglect among rural preschool aged children in Xi an were 32.4% and 38.27±6.70, respectively. Statistically significant differences were detected in neglect rates and neglect degrees among preschool children of different genders and grade levels ( χ 2=30.41, 15.15, t/F =4.92,7.03, all P <0.05). Statistically significant differences were also detected in neglect rates and neglect degrees among preschool children from whether only one child, different family structures, numbers of children in a family and families with different annual incomes ( χ 2=29.22, 10.41 , 31.99, 186.47, t/F =-9.96, 5.50, 33.57, 68.63, all P <0.05). In multi child families, there was a statistically significant difference in neglect degree among children with different birth orders ( F =4.25, P <0.05), but there was no statistically significant difference in neglect rate ( χ 2=5.73, P >0.05). Among all subgroups, the highest neglect rates and neglect degrees were observed in children from multi child families(35.0%,39.00±6.71), other family types(50.0%，42.38±12.34) and families with three children(39.9%，39.50±7.43). Lower annual family income was associated with higher neglect rates and neglect degrees among preschool children( χ 2 trend =186.47， F =270.68，both P <0.05). Conclusions Under the multiple child policy, the neglect of preschool children in rural areas of Xi an is quite severe, particularly in families with multiple children and low income households. Targeted interventions should be implemented for high risk groups.

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.

Optical brain-computer interface (OBCI) represents an emerging class of neural interaction technologies that use “light” as an information carrier to enable the acquisition, decoding, and modulation of neural signals. Compared with conventional electrical brain-computer interface (BCI), OBCI demonstrates distinct advantages in spatial resolution, cell-type specificity, and the capacity for simultaneous multiparametric monitoring. Driven by rapid advances in functional near-infrared spectroscopy, optical neuroimaging, and optogenetics, optical approaches have progressively extended across the full “read, decode, write” continuum of neural activity, providing a novel technological framework for the development of high-precision closed-loop brain-computer systems. This review systematically summarizes the principal technological strategies and recent advances in OBCI, and further discusses the key challenges encountered during clinical translation, as well as future development direction.

Objective To investigate the possible association between cross-domain associative memory(AM)impairment and hippocampal subfield volumes in patients with schizophrenia(SCZ).Methods We enrolled 28 SCZ patients from Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,and 28 healthy controls(HCs)between 2019 and 2021.Based on an innovative AM paradigm and automated segmentation,3D-T1 weighted data of the objects were processed with PhiPipe and FreeSurfer.Differences in subfield volums between the two groups were analyzed using ANCOVA,while their relationship with AM scores was assessed using Pearson correlation.Results SCZ patients exhibited significantly poorer AM performance across three conditions compared with HCs.Marginally significant reductions were observed in the total volume of bilateral hippocampus,encompassing both the hippocampal head and body.Significant volume reductions were identified in the bilateral presubiculum and parasubiculum.The volumes of bilateral presubiculum head(r=0.273,P=0.042),parasubiculum(r=0.397,P=0.002),and CA1 head(r=0.382,P=0.004)exhibited positive correlations with cross-domain AM performance.Conclusion The bilateral presubiculum and parasubiculum,as hippocampal subregions significantly associated with cross-modal AM deficits in SCZ,may play a crucial role in the pathology of AM.

Aim To explore the therapeutic effect and mechanism of Qingjie Huagong decoction in modulating PI3K/AKT/NF-κB signaling pathway in inflammatory response of acute pancreatitis(AP)mice.Methods Twenty-four mice were randomly divided into Blank group,Model group,Ustekin group,and Qingjie Hua-gong decoction group,with six mice in each group.The AP model was prepared by using rain frogin.Serum α-AMS,PNLP,IL-1β,IL-6,IL-8,IL-18,and TNF-α lev-els were detected by ELISA;the pancreatic pathology was detected by HE staining;the expressions of PI3K,AKT,and NF-κB-related proteins and mRNAs were de-tected by immunohistochemistry,Western blot,and RT-qPCR.Results Compared with the blank group,the model group showed obvious pathological damage to the pancreas,with significantly higher serum α-AMS,PN-LP,IL-1β,IL-6,IL-8,IL-18,and TNF-α levels(P＜0.01),and significantly higher levels of PI3K,AKT,and NF-κB-related proteins and mRNA expression(P＜0.01).Compared with the model group,both the Qingjie Huagong decoction group and the ustekin group improved the histopathological changes in the pancreas of AP mice,decreased the serum α-AMS,PNLP,IL-1β,IL-6,IL-8,IL-18,and TNF-α levels,and down-reg-ulated the expression levels of pancreatic PI3K,AKT,NF-κB-related proteins and mRNA(P＜0.05 or P＜0.01).Conclusion Qingjie Huagong decoction may inhibit the inflammatory response and protect pancreat-ic tissues by regulating the expression of PI3K/AKT/NF-κB signaling pathway.

Objective:To evaluate the clinical outcomes of right vertical infra-axillary thoracotomy technique (RVIAT) versus traditional median sternotomy (MS) for ventricular septal defect (VSD) repair in infants weighing ≤5 kg.The study further investigates the safety and feasibility of these two surgical approaches.Methods:Retrospective case-series study.Three hundred and fourteen children weighing no more than 5 kg who received VSD repair in Fuwai Central China Cardiovascular Hospital from January 2020 to June 2024 were analysized.Of these children, 252 cases who underwent RVIAT were included in the RVIAT group, and 62 cases who received traditional MS were classified as the MS group.Clinical data such as day age, body mass, the VSD type and diameter were compared between the 2 groups.The operation time, extracorporeal circulation time, block and postoperative mechanical ventilation time, intensive care unit (ICU) treatment time, 24-hour postoperative chest drainage volume and intraoperative bleeding, postoperative secondary intubation, and cardiac arrhythmia of the 2 groups of patients were recorded.Children with unstable blood pressure and active bleeding after taking vasoactive and hemostatic drugs underwent a secondary surgery.The peak airway pressure, oxygenation index, and lung dynamic compliance of the 2 groups of children were recorded before chest opening, immediately after surgery, and 24 hours after surgery. t test, χ2 test and rank sum test were used to compare the clinical data, perioperative results, complications and lung function data of the two groups. Results:(1) No significant differences were observed between the two groups in gender, age, body mass, VSD type and diameter, preoperative pneumonia, and mechanical ventilation rate (all P>0.05).(2) One-stage VSD repair was successfully completed in all cases.In the MS group, 1 infant required a secondary surgery for pericardial tamponade due to excessive bleeding.In the RVIAT group, 1 case necessitated a secondary surgery for third-degree atrioventricular block.Two cases in the MS group and 3 cases in the RVIAT group suffered postoperative arrhythmia, all of who supplemented electrolytes, received a secondary surgery to remove patches and adjust suture positions, and took antiarrhythmic drugs to restore sinus rhythm.(3) The operation time [(137.4±9.1) minutes], hospital stay [(8.2±2.1) days], postoperative mechanical ventilation time [8.0 (6.0, 13.0) hours], postoperative ICU stay [2.9 (2.0, 3.6) days], 24-hour postoperative chest drainage volume [(11.3±1.2) mL], intraoperative bleeding [(11.6±1.2) mL], and hospital costs [(70±7) thousand yuan], the postoperative incidence of incision infection [0.4%(1/252)] and the postoperative incidence of sternal malformation (0) in the RVIAT group were significantly lower than those in the MS group [(151.9±20.2) minutes, (13.1±1.7) days, 12.0 (9.0, 15.0) hours, 2.9 (2.5, 3.7) days, (14.3±1.6) mL, (15.8±2.0) mL, (78±4) thousand yuan, 4.8%(3/62), and 4.8%(3/62), respectively] (all P<0.05).There was no significant difference in extracorporeal circulation time, aortic occlusion time, postoperative arrhythmia rate, residual shunt, and atelectasis between the two groups (all P>0.05).(4) The peak airway pressure, oxygenation index and lung dynamic compliance before chest opening, immediately after surgery, and 24 hours after surgery did not differ significantly between the two groups (all P>0.05). Conclusions:In infants with low body mass (≤5 kg), RVIAT for VSD repair offers good exposure through a small incision, capable of reducing operation time, intraoperative bleeding, postoperative hospital stay, and hospital costs, and facilitating faster recovery.With high safety and effects, RVIAT can be considered as a viable alternative to MS.
