BackgroundIn recent years， the incidence of depression among adolescents has been increasing steadily， posing a serious threat to their physical and mental health and even leading to severe consequences such as self-harm and suicide. At the same time， the detection rate of subclinical depression symptoms among adolescents is even higher. Although these symptoms do not meet the clinical diagnostic criteria， they have significantly affected their quality of life， and their persistence over time may further develop into depression. Therefore， in-depth exploration of adolescent depression symptoms and the predictive factors holds significant practical significance and research value. However， up to now， no large-scale investigation and research on depression symptoms among children and adolescents has been conducted in Inner Mongolia Autonomous Region. ObjectiveTo understand the prevalence of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region， in order to provide references for formulating scientific and effective prevention strategies and intervention measures. MethodsBy using the cluster stratified random sampling method， 6 281 students from the third grade of primary school to the second grade of high school in 12 leagues and cities of Inner Mongolia Autonomous Region were selected in March 2024. A self-designed questionnaire and the Self-rating Depression Scale （SDS） were used for on-site investigation. ResultsA total of 6 058 （96.45%） children and adolescents completed the valid questionnaire survey， and 2 728 cases （45.03%） were found to have depressive symptoms. There were statistically significant differences in the detection rates of depressive symptoms among children and adolescents of different genders， ages， whether they were only children， different family types， family monthly income， parents' educational levels， and whether the mother was employed （χ²=33.769， 40.618， 48.593， 29.972， 142.648， 195.999， 168.190， 5.445， P<0.05 or 0.01）.The results of the Logistic regression analysis showed that for children and adolescents， being female， aged between 12 and 16， over 16 years old， not being an only child， living in a reconstituted family， having a monthly family income of less than 5 000 yuan， and having parents with an education level of primary school or below were predictors of depressive symptoms （OR=1.241， 1.427， 1.273， 1.177， 1.549， 1.278， 1.462， 1.417， 1.514， 1.929， 1.660， 1.528， P<0.05 or 0.01）. ConclusionThe detection rate of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Factors that may predict depressive symptoms in children and adolescents include female gender， ages between 12 and 16， ages over 16 years old， non-only children， families with a restructured structure， monthly family income of less than 5 000 yuan， and parents with an education level of primary school or below. ［Funded by Science and Technology Planning Project of the Inner Mongolia Autonomous Region （number， 2022YFSH0119）］

ObjectiveTo investigate the mechanism by which Shengjiang Pingchuan Zhike pills （SPZP） alleviate airway injury in the rat model of cough variant asthma （CVA） via regulating autophagy through activating the adenosine monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR）/Unc-51-like autophagy activating kinase 1 （ULK1） signaling pathway based on transcriptomics， thus providing experimental evidence for the clinical application of SPZP. MethodsForty SPF-grade SD rats were enrolled in the present study and randomly via the random number table method assigned into four groups： a blank group， a model group， a SPZP （2 160 mg·kg^-1·d^-1） group， and a positive drug （montelukast sodium， MTL， 0.9 mg·kg^-1·d^-1）group， with 10 rats in each group. After one week of adaptive feeding， the rat model of cough variant asthma （CVA） was established by two-week sensitization with ovalbumin （OVA） and aluminium hydroxide， followed by capsaicin atomization challenge. Rats in the blank group received an equal volume of normal saline during modeling. Upon successful modeling， rats in the SPZP group and positive drug group were administrated with SPZP suspension and MTL solution， respectively， while those in the blank and model groups received the same dose of normal saline by gavage. The whole intervention lasted for 21 consecutive days. After the intervention， general behaviors of rats in each group were observed. Pulmonary function indicators were subsequently detected. Hematoxylin-eosin （HE） staining was performed to visualize the pathological morphology of the lung tissue， and periodic acid-Schiff （PAS） staining was adopted to evaluate airway mucus secretion. Transcriptomic sequencing was conducted to screen differentially expressed genes in the lung tissue across groups. The levels of inflammatory cytokines including interleukin （IL）-4， IL-5， immunoglobulin E （IgE）， and interferon-γ （IFN-γ） in the bronchoalveolar lavage fluid （BALF） were quantified by enzyme-linked immunosorbent assay （ELISA）. Immunofluorescence staining was used for detecting the co-localization of autophagy-related protein Beclin-1 and phosphorylated mammalian target of rapamycin （p-mTOR）. Transmission electron microscopy was employed to count autophagosomes and observe mitochondrial morphological changes in the lung tissue. Western blot assay was utilized to measure the expression levels of AMPK/mTOR/ULK1 axis-related proteins， including AMPK， phosphorylated adenosine monophosphate-activated protein kinase （p-AMPK）， mTOR， phosphorylated mammalian target of rapamycin （p-mTOR）， ULK1， and phosphorylated Unc-51-like autophagy activating kinase 1 （p-ULK1） as well as the autophagy biomarkers Beclin-1 and selective autophagy adaptor protein p62 in lung specimens. ResultsCompared with the blank group， the model group exhibited markedly elevated cough frequency accompanied by wheezing and stridor， dull fur， poor mental activity， diminished motor activity， accelerated respiratory rate， and weakened sensory response and mobility to external stimuli， accompanied by a declining tendency of body mass. Meanwhile， the model group exhibited decreased dynamic lung compliance， increased airway resistance （P<0.01）， severe pathological damage and excessive mucus secretion in the lung tissue （P<0.01）， and elevated levels of IL-4， IL-5， and IgE and declined level of IFN-γ in the BALF （P<0.01）. Ultrastructural observation revealed damaged mitochondrial morphology and a sharp reduction in the number of autophagosomes in the lung tissue. In addition， the expression of p-AMPK， p-ULK1， and Beclin-1 were downregulated， whereas p-mTOR and p62 were highly expressed （P<0.05， P<0.01） in the model group. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analyses demonstrated significant enrichment of AMPK， mTOR， and autophagy-related pathways. Compared with the model group， both the positive drug group and SPZP group obtained visible improvements in general behavioral manifestations and obvious recovery of pulmonary function indicators （P<0.05）， alleviated pulmonary pathological lesions and suppressed excessive airway mucus secretion （P<0.05）， recovered levels of inflammatory cytokines in the BALF （P<0.05）， restored mitochondrial morphology， increased autophagosomes， upregulated expression levels of p-AMPK， p-ULK1， and Beclin-1， and downregulated expression levels of p-mTOR and p62 （P<0.05）. ConclusionSPZP can effectively ameliorate airway inflammation and improve the pulmonary function in the rat model of CVA by activating the AMPK/mTOR/ULK1 signaling pathway， enhancing autophagy in the lung tissue， and inhibiting excessive airway mucus secretion and immune inflammatory imbalance.

Objective To systematically evaluate the risk factors for metabolic syndrome in hospitalized patients with schizophrenia in China.Methods Relevant observational studies were retrieved for Chinese schizophrenia patients with metabolic syndrome in Databases,with a retrieval period from the database establishment date to January 12 2025.Two researchers independently screened the literature,extracted data and evaluated the quality of the studies,and a total of 16 articles were included for Meta analysis.Results Age,body mass index,smoking history,disease duration,family history of metabolic syndrome,diabetes history,hypertension history,chlorantraniliprole use,olanzapine use,interleukin-6 levels,leptin levels,triglyceride levels,and high-density lipoprotein cholesterol levels were significant risk factors for metabolic syndrome in hospitalized Chinese schizophrenia patients(P＜0.05).Moderate recreational exercise served as a protective factor(P＜0.05).Conclusion There are many influencing factors for the association of metabolic syndrome in hospitalized patients with schizophrenia in China,and moderate exercise is a protective factor for the association of metabolic syndrome in schizophrenia.In clinical practice,high-risk groups of metabolic syndrome can be actively screened according to relevant risk factors.

Objective:To study the results of detection of pulmonary nodules among military flying personnel and analyze the contributors to pulmonary nodules so as to provide data for early prevention and interventions.Methods:The physical examination data of 1 465 military flying personnel was retrospectively analyzed who had received the annual health checkup and undergone chest CT examinations at Lintong Rehabilitation and Recuperation Center. They were grouped by age (<40 years and ≥40 years), flying hour (<1 000 h and ≥1 000 h) and type of personnel [pilots and air support (technical) personnel]. The detection rates of pulmonary nodules among flying personnel were compared across groups, and a multivariate Logistic regression analysis was conducted to analyze the contributing factors to pulmonary nodules.Results:Among the 1 465 military flying personnel, 212 cases (14.47%) with pulmonary nodules were detected. A total of 230 pulmonary nodules were detected, including 35 pulmonary nodules (15.22%) in the left upper lung, 42 pulmonary nodules (18.26%) in the left lower lung, 52 pulmonary nodules (22.61%) in the right upper lung, 47 pulmonary nodules (20.43%) in the right middle lung, and 54 pulmonary nodules (23.48%) in the right lower lung. The detection rate of pulmonary nodules among military flying personnel in the ≥1 000 h group was higher than in the <1 000 h group, and the difference was statistically significant ( χ2=4.14, P=0.042). More pulmonary nodules were detected among military flying personnel who smoked than among those who did not, and the difference was statistically significant ( χ2=9.34, P=0.002). Age, types of personnel, body mass index, and complications with other lung diseases made no significant difference in the detection rate of pulmonary nodules (all P>0.05). Multivariate Logistic regression analysis showed that smoking was a risk factor for pulmonary nodules ( OR=1.692, 95% CI: 1.217-2.351). Conclusions:Among military flying personnel, pulmonary nodules are more likely to occur in the right lung. Smoking is an independent risk factor for pulmonary nodules, suggesting that routine chest CT screening should be carried out during the annual physical examinations of military flying personnel in order to exercise early interventions.

Aim To investigate the preventive and therapeutic effect of crocetin(Cro)on acute intestinal injury induced by radiation(RT)and its related mech-anism.Methods Forty mice were randomly divided into four groups:control group,radiation group(RT group),low-dose Cro intervention group(RT+Low-dose Cro group)and high-dose Cro intervention group(RT+High-dose Cro group).The RT group was given a single dose of 12Gy radiation to the abdomen.The Cro intervention group was treated with 25 mg·kg-1 and 100 mg·kg-1 Cro by gavage once a day before ra-diation until seven days after radiation.The mice in each group were weighed.The morphology of intestinal tissue was observed by HE staining.The levels of in-testinal inflammatory factors and oxidative stress were detected.The expressions of Lgr5,Ki67,lysozyme,ZO-1 and Occludin in small intestine tissuewere detected by immunohistochemistry.The expressions of Nrf2/HO-1 and NF-κB signaling related proteinswere detected by Western blot.Results Compared to the control group,mice in the RT group exhibited a significant decrease in body weight(P＜0.01).Additionally,they dis-played evident morphological damage to the small in-testine and elevated levels of pro-inflammatory factors(TNF-α,IL-6)as well as oxidative stress markers(in-creased ROS and MDA levels,decreased GSH and SOD activities)(P＜0.01).Moreover,there was an in-crease in Lgr5 and Ki67 positive cells within the crypts(P＜0.01).The expressions of Occludin,lysozyme,ZO-1,and HO-1 were reduced in small intestine while Nrf2,p-p65,and p-IκB expressions increased(P＜0.01).The improvements in the Cro group were sig-nificantly greater than the RT group(P＜0.01),with a more pronounced effect observed in the high-dose group.Conclusions Cro has a preventive and thera-peutic effect on radiation-induced intestinal injury,and its mechanism is related to anti-inflammation,anti-oxi-dation,improvement of intestinal barrier function,pro-motion of intestinal stem cell regeneration,enhance-ment of Nrf2/HO-1 signaling and reduction of NF-κB signaling activity.

Objective:To explore the relationship between the dynamic alterations of immune cell subsets in a patient with autoimmune encephalitis and the clinical relapses.Methods:For a patient with multiple relapses of anti-N-methyl-D-aspartate receptor encephalitis superimposed with myelin oligodendrocyte glycoprotein antibody-associated disease who visited Peking Union Medical College Hospital on July 18, 2018, the lymphocyte subsets were monitored dynamically over a long period and the relationship between lymphocyte subsets and the relapses was summarized.Results:The 38-year old male patient experienced a total of 5 episodes (including 4 relapses) during the six-year immunotherapy and follow-up process, and responded well to first-line and maintenance immunotherapy. His relapses occurred during drug reduction. Finally, the neurological symptoms resolved after rituximab treatment. A total of 39 tests of peripheral blood lymphocyte subsets were conducted during the follow-up, and 5 peaks of elevated CD19 positive B cells, 9 peaks of elevated CD3 positive T cells and 11 peaks of elevated natural killer cells were observed. The peak period of peripheral blood CD19 positive B cells exactly coincided with clinical relapses. While the consistency rates of clinical relapse and the peaks of peripheral blood CD3 positive T cells and natural killer cells were 5/9 and 2/11, respectively.Conclusions:The dynamic alterations of CD19 positive B cells in peripheral blood are correlated with the clinical relapse of autoimmune encephalitis and can predict clinical relapse.
