BackgroundNon-suicidal self-injury （NSSI） has become a public health concern of wide interest. Adolescents with depressive disorder are at high risk of NSSI behaviors. Previous studies have mostly focused on analyzing factors associated with NSSI behaviors， while research on developing visual models that are intuitive， quantifiable， and suitable for rapid clinical assessment is relatively limited. ObjectiveTo investigate the risk factors for NSSI behaviors in adolescents with depressive disorder， and to construct a nomogram prediction model for the risk of NSSI behaviors occurrence， so as to provide a quantitative tool for clinical rapid assessment of the occurrence risk of NSSI behaviors in this population. MethodsA cross-sectional study was conducted. A total of 448 adolescent patients diagnosed with depressive disorder who attended the Mental Health Department of The Second Hospital， Lanzhou University from February to December 2025 and met the diagnostic criteria for depressive disorder as specified in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） were enrolled. All participants were randomly divided into the modeling group （n=313） and the validation group （n=135） at a ratio of 7∶3. Assessments were performed using the Self-rating Depression Scale （SDS）， the Self-rating Anxiety Scale （SAS）， the Barratt Impulsiveness Scale-11 （BIS-11）， the Childhood Trauma Questionnaire-short form （CTQ-SF）， and the Pittsburgh Sleep Quality Index （PSQI）. Binary Logistic regression analysis was applied to screen independent predictors of NSSI behaviors in the modeling group， and a nomogram was constructed accordingly. The receiver operating characteristic （ROC） curve， calibration curve， and decision curve analysis （DCA） were used to evaluate the discrimination， calibration and clinical utility of the model， respectively. ResultsBinary Logistic regression analysis revealed that younger age， female sex， higher SDS score， higher BIS-11 score， higher CTQ-SF score， and higher PSQI score were risk factors for NSSI behaviors in adolescent patients with depressive disorder （OR=0.816， 2.671， 1.131， 1.030， 1.064， 1.102， P<0.05 or 0.01）. The Hosmer-Lemeshow test of the nomogram prediction model constructed based on these six indicators showed a good fit （χ²=15.144， P=0.056）. Model validation showed that the AUC was 0.895 for the modeling group and 0.891 for the validation group. The calibration curves suggested that the mean absolute errors between the actual values and the predicted values were 0.043 and 0.023， respectively. Decision curve analysis indicated that the model provided a clear net clinical benefit when the risk threshold was greater than 0.11. ConclusionThe nomogram model based on six indicators （age， sex， depressive symptom severity， impulsivity， childhood trauma， and sleep quality） for predicting NSSI risk in adolescent patients with depressive disorder exhibits good discrimination， calibration， and clinical application value. ［Funded by National Natural Science Foundation of China （number， 82560281）； Gansu Provincial Science and Technology Program （number， 25JRRA618）； Gansu Provincial Health Industry Research Project （number， GSWSKY2025-13）； The College Students' Innovation and Entrepreneurship Training Program of the Second Clinical Medical College of Lanzhou University （number， 20250050060）］

Major depressive disorder is a common mental disorder,one of the core symptoms of which is anhedonia,characterized by a reduced ability to respond to pleasurable stimuli.Brain images of patients with major depressive disorders with anhedonia show the following features:reduced volume or cortical thickness in brain regions such as the striatum and temporal lobe,changes in the microstructure of white matter tracts,abnormal neuronal activity in the frontal lobe,temporal lobe,and limbic system,and altered connectivity in the default mode network,reward network,and fronto-parietal network.Additionally,factors such as stress,gene expression,the glutamate system,and biological rhythms may also influence anhedonia.The neurobiological mechanisms of anhedonia are intricate,and are crucial for the diagnosis,treatment,and prognosis of depressive disorders.

Objective To observe the clinical efficacy of Shengdi Xiexin Decoction combined with proton pump inhibitors(PPIs)in the treatment of acute non-variceal upper gastrointestinal bleeding(ANVUGIB)with stomach-heat congestion syndrome.Methods Sixty-two patients with ANVUGIB of stomach-heat congestion syndrome admitted to Dongguan Hospital of Guangzhou University of Chinese Medicine between January and December 2024 were randomly divided into a treatment group(n=31)and a control group(n=31)using a random number table.The control group received conventional western therapy(e.g.,Omeprazole Sodium),while the treatment group additionally received Shengdi Xiexin Decoction.Both groups were treated for 7 days,followed by 8 weeks of follow-up.The changes in traditional Chinese medicine(TCM)syndrome scores,hematological parameters[hemoglobin(Hb),red blood cells(RBC),hematocrit(Hct),albumin(ALB)],tissue perfusion and metabolic markers[blood urea nitrogen/creatinine ratio(BUN/Cr),lactate(Lac)levels],hemostasis time,time to resume oral diet,hospital stay duration,hospitalization costs,and rebleeding rates were observed to evaluate the clinical efficacy and drug safety.Results(1)After 7 days of treatment,the total effective rate was significantly higher in the treatment group(90.32％,28/31)than that in the control group(74.19％,23/31).The intergroup comparison(by chi-square test)showed that the treatment group,efficacy was superior to that of the control group(P＜0.05).(2)The treatment group showed significantly short hemostasis time,time to resume oral diet,and hospital stay duration(P＜0.05),as well as significantly low hospitalization costs(P＜0.05)compared to the control group.(3)Both groups exhibited significant reductions in the scores of epigastric burning pain,abdominal distension,acid regurgitation,restlessness,excessive thirst,scanty dark uring and dry stools,and total TCM syndrome scores(P＜0.05).The treatment group demonstrated significantly greater improvements in the scores of abdominal distension,acid regurgitation,restlessness,dark uring and dry stools,and total TCM syndrome scores(P＜0.05),while no significant differences were observed in epigastric burning pain and excessive thirst(P＞0.05).(4)Hb and Hct levels increased significantly in both groups(P＜0.05),with a greater increase in the treatment group(P＜0.05).Although RBC and ALB levels showed an upward trend,no significant differences were observed between groups(P＞0.05).Following treatment,intergroup comparisons revealed that the treatment group demonstrated significantly greater increases in Hb and Hct levels than the control group(P＜0.05).In contrast,the two groups showed comparable effects in elevating RBC and ALB levels,with no statistically significant differences(P＞0.05).(5)BUN/Cr ratio and Lac levels decreased significantly in both groups(P＜0.05),with a more pronounced reduction in the treatment group(P＜0.05).(6)No significant differences were found in early or delayed rebleeding rates between groups(P＞0.05).(7)Neither group experienced significant adverse events.Conclusion Shengdi Xiexin Decoction combined with PPIs significantly improves clinical outcomes in ANVUGIB patients with stomach-heat congestion syndrome.It is effective on enhancing hematological parameters,correcting tissue hypoperfusion,alleviating symptoms,shortening hemostasis time and hospitalization durations,and reducing medical costs,demonstrating excellent safety.

[Objective]To investigate the non-suicidal self-injury(NSSI)behaviors in adolescents with depressive disorder,analyze related influencing factors,and provide theoretical basis and reference for the prevention and treatment of NSSI.[Methods]According to DSM-5 criteria,95 depressive adolescents were divided into two groups:one with NSSI(NSSI group)and one without NSSI(nNSSI group).All patients were assessed with Adolescent Non-suicidal Self-injury Assessment Questionnaire(ANSAQ),Self-Rating Depression Scale(SDS),Self-Rating Anxiety Scale(SAS),Simplified Coping Style Questionnaire(SCSQ),Experiences in Close Relationships-Relationship Structures Scale(ECR-RS),and Childhood Trauma Questionnaire-Short Form(CTQ-SF).The inter-group differences were compared.The influencing factors of NSSI were analyzed by using binary logistic regression.[Results]Of the 95 depressive adolescents,59 cases of NSSI were identified,with a detection rate of 62.11%.NSSI group had higher scores than nNSSI group on SDS,SAS,negative coping style,paternal attachment anxiety,maternal attachment anxiety and avoidance,CTQ-SF total score,emotional neglect,physical neglect,emotional abuse,and sexual abuse(all P<0.05).Binary logistic regression analysis showed that anxiety,negative coping style,maternal attachment avoidance and emotional abuse increased the risk of NSSI among adolescents with depressive disorders(all P<0.05).[Conclusions]Adolescents with depression have a high incidence of NSSI behaviors,which is related to anxiety,negative coping style,maternal attachment avoidance and emotional abuse.In addition to improving patients' depression and anxiety in clinical setting,attention should also be paid to patients' coping styles,parent-child relationship and childhood trauma to reduce the occurrence of NSSI behaviors.

Cognitive dysfunction is the impairment of higher brain functions.Cognitive impairment caused by neuropsychiatric diseases has caused serious impact on patients'quality of life and the outcome of the disease.The transcranial alternating current stimulation(tACS)improves cognitive function by modulating neural oscillations of specific frequencies,affecting the release of neurotransmitters such as serotonin and dopamine,and enhancing local and distal synchronization of brain networks.Specific frequencies of tACS can improve the cognitive impairment caused by Alzheimer disease(AD),schizophrenia,and depression,among which the gamma and theta frequencies of tACS have the most significant effects on cognitive function.tACS has high safety and low operational difficulty,and has great potential to improve cognitive function.

Depression is a common mental disorder characterized primarily by low mood accompanied by cognitive and behavioral changes. The commonly used antidepressants are not fast onset. Even with a long term pharmacotherapy, relapse rate is still quite high. Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation technique that has been increasingly used in the treatment of depression in recent years. Since depression is associated with abnormalities in endogenous neural oscillations and synaptic plasticity in the brain, tACS can influence these process, thereby treating depression. Different frequencies of tACS stimulation can improve depressive symptoms, with gamma (γ) and alpha (α) frequencies receiving the most attention. This article primarily reviews the potential mechanisms of tACS and the application of tACS at different frequencies in treating depression, aiming to further explore the feasibility of tACS in the treatment of depression.

Objective:To evaluate the effect of maternal depressed mood at pregnancy and postpartum on the risk of emotional or behavioral disorders of offspring by meta-analysis. Methods:The following Mesh words and free words were searched in 7 online databases, including the PubMed, Embase, Web of Knowledge, PsycINFO, Cochrane, WanFang databases and China National Knowledge Infrastructure from January 1, 2000 to October 31, 2020: " maternal" AND " depression" AND " child OR offspring" AND " neuropsychology" . According to the inclusion and exclusion criteria, case-control and cohort studies reporting the effect of maternal depressed mood during pregnancy or postpartum on the risk of emotional or behavioral disorders of offspring were reviewed. Meta-analysis was performed by RevMan 5.3. Results:Fourteen studies involving 3 914 in the case group and 17 016 in the control group were included.Children whose mother with depressed mood during pregnancy or postpartum had 2.03 times risk of emotional or behavioral disorders than those whose mothers without depressed mood ( OR=2.03, 95% CI: 1.55-2.65). Both depressed mood at pregnancy and postpartum could increase the incidence of emotional or behavioral disorders in children, but there was no significant difference between these two periods ( Z=-0.371, 95% CI: 0.796-1.168). Moreover, the effect of maternal depressed mood on emotional or behavioral disorders in offspring could last to the preschool and school period, and the children in the school period may have higher incidence of emotional or behavioral disorders than those during the preschool period ( Z=-2.340, 95% CI: 0.643-0.962). Conclusions:Maternal depressed mood can increase the incidence of emotional or behavioral disorders in offspring, which are long-lasting and do not decrease with age.

Objective::This survey was designed to understand the misconceptions about labor epidurals.Methods::This voluntary and anonymous online survey on wenjuan.com was conducted from September 1 st, 2015 to January 1 st, 2016 via mainly WeChat groups dedicated to perinatal healthcare providers in China. The questionnaire included items inquiring the knowledge and opinions about labor epidural analgesia related to maternal complications, baby safety, and effect on laboring. Incomplete surveys were excluded from the data analysis. The data was presented as percentages and a Chi-square test or Fisher’s exact test, as appreciate, was used to quantitatively compare the results. Results::A total of 1412 respondents completed surveys with 42.9% (606/1412) of them being anesthesiologists, 35.1% (495/1412) being obstetricians, 11.8% (167/1412) being midwives, 3.7% (52/1412) being labor and delivery nurses, and 6.5% (92/1412) being hospital administrators and unspecified. The study revealed a lack of knowledge in labor pain control. Although 82.4% (1164/1412) of respondents were familiar with labor epidural analgesia, 8.9% (126/1412) did not know how it works, and 1.1% (15/1412) never heard it in a multiple-choice question. The three main groups (anesthesiologists, obstetricians, and midwives/labor and delivery nurses) were chosen for comparisons. Opinions among these three groups concerning five questions in the three main concerns were evaluated using a statistical significance of P<0.05. Conclusion::The results in our survey indicated an urgent need of continuing medical education to multidisciplinary specialties to improve evidence-based medical practices as these misconceptions have existed for over 10 years in the medical professionals. Lack of public awareness fueled by misconceptions related to labor epidural analgesia may be associated with a lack of professional knowledge. Correct knowledge in professionals needs to be disseminated to the public in order to dispel possible misconceptions and rumors about labor epidural analgesia. This would not only enhance patient understanding of their care but also improve maternal, fetal, and neonatal outcomes.
