ObjectiveTo investigate the material basis of the pathogenesis of cerebral ischemic injury with blood stasis and toxin syndrome and to explore the protective effects of Huayu Jiedu prescription (HYJDP) on neutrophil extracellular trap-related cell death (NETosis) in cerebral ischemic injury following acute cerebral infarction. MethodsSeventy-two Sprague-Dawley (SD) rats were randomly divided into six groups (n=12 per group): sham operation (Sham) group, blood stasis and toxin model (Model) group, low-, medium-, and high-dose HYJDP groups (HYJDP-L, HYJDP-M, and HYJDP-H; 9, 18, and 36 g·kg-1, respectively), and butylphthalide (NBP) group (0.06 g·kg-1). Except for the Sham group, rats in all other groups were subjected to carrageenan/dry yeast combined with a modified intraluminal filament method to establish a focal cerebral ischemia model of the middle cerebral artery with blood stasis and toxin syndrome. Neurological function was evaluated at 24 h after modeling using the Zea-Longa neurological deficit score. Cerebral infarction rate was assessed by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Pathological morphology of brain tissue was observed using hematoxylin-eosin (HE) staining. Enzyme-linked immunosorbent assay (ELISA) was used to determine serum levels of interleukin-8 (IL-8), myeloperoxidase-DNA complexes (MPO-DNA), and citrullinated histone H3 (CitH3). Protein expression of phosphorylated phosphatidylinositol 3-kinase (p-PI3K), protein kinase B (p-Akt), mammalian target of rapamycin (p-mTOR), sequestosome 1 (p62), and CitH3 in brain tissue was detected by Western blot. Immunofluorescence (IF) was used to detect the expression of neutrophil-specific marker Ly6G, CitH3, and neuron-specific nuclear protein (NeuN) in brain tissue. ResultsCompared with the Sham group, neurological deficit scores and cerebral infarction rates in the model group were significantly increased (P<0.01 for both). HE staining showed varying degrees of neuronal degeneration and necrosis, characterized by blurred neuronal structures, nuclear pyknosis and fragmentation, cytoplasmic dissolution into a vacuolated reticular pattern, and mild glial cell proliferation. ELISA results showed that serum levels of IL-8, MPO-DNA, and CitH3 were significantly increased (P<0.01). Western blot analysis demonstrated decreased expression of p-PI3K, p-Akt, p-mTOR, and p62, while CitH3 expression was significantly increased (P<0.01). IF results showed an increased number of NETs+ cells and a significant decrease in NeuN+ cells (P<0.01). Compared with the Model group, neurological deficit scores in the HYJDP-H group were significantly decreased (P<0.05), and cerebral infarction rates in the HYJDP-H and NBP groups were significantly reduced (P<0.01). HE staining showed that brain tissue damage was markedly alleviated in the HYJDP-H group. ELISA results showed that levels of IL-8, MPO-DNA, and CitH3 were significantly decreased in the HYJDP-M, HYJDP-H, and NBP groups (P<0.01). Western blot analysis showed that expression of p-PI3K, p-Akt, p-mTOR, and p62 was significantly increased in the HYJDP-H and NBP groups, while CitH3 expression was significantly reduced in all drug intervention groups (P<0.01). IF results showed that the number of NETs+ cells was significantly decreased and the number of NeuN⁺ cells was significantly increased in all drug intervention groups (P<0.01). ConclusionNETs may be the material basis of the pathogenesis of cerebral ischemic injury characterized by blood stasis and toxin. HYJDP can regulate the PI3K/Akt/mTOR signaling pathway, reduce the release of pro-inflammatory mediators and NETosis-related products, alleviate cerebral ischemic injury caused by autophagy-dependent NETosis, and thereby exert a neuroprotective effect.

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.

OBJECTIVE To establish a high-risk medication list and preventive and therapeutic measures for drug-induced hypofibrinogenemia, and to provide a reference for the prevention and treatment of this condition. METHODS By integrating domestic and international case reports, retrospective case-control studies, and spontaneous adverse drug reaction reporting databases, 19 domestically marketed high-risk drugs for drug-induced hypofibrinogenemia were identified. Based on the clinical characteristics and mechanisms of these drugs, relevant risk factors were systematically reviewed, and existing treatment options were summarized, leading to the preliminary development of recommended preventive and therapeutic measures. A two-round Delphi consultation was conducted to evaluate, revise, and ultimately reach consensus on the preliminary findings, using a mean importance score of ≥3.5 points for indicators and a coefficient of variation <0.3 as screening criteria. RESULTS The coefficient of expert authority for both rounds of expert consultation was 0.904. In the first round, the Kendall coordination coefficients (Kendall’s W ) for the high-risk medication list and the proposed preventive and therapeutic measures were 0.390 and 0.223 ( P <0.05), respectively. In the second round, the Kendall’s W were 0.227 and 0.200 ( P <0.05), respectively. After two rounds of expert consultation and discussion, 11 high-risk drugs for drug-induced hypofibrinogenemia, represented by hemocoagulase and certain anti-infective agents, were ultimately identified, along with 5 preventive and therapeutic measures spanning the entire process of “pre-medication assessment, intra-medication monitoring, and bleeding event management”. CONCLUSIONS This study has established a scientific and reliable high-risk medication list, and corresponding preventive and therapeutic measures for drug-induced hypofibrinogenemia, providing a theoretical basis and practical support for the early identification, stratified management, and precise intervention of this condition.
4.Home food environment and its association with overweight and obesity among primary school students
Chinese Journal of School Health 2026;47(5):629-632
Objective:
To investigate the association between the home food environment and overweight and obesity among primary school students, so as to provide scientific evidence for developing targeted family based intervention strategies.
Methods:
From May to June 2017, a total of 3 670 students in grades 4-6 were selected from 26 schools in 13 districts and counties of Shenyang using multistage random cluster sampling. A questionnaire survey was used to assess the home food environment and sociodemographic factors. Standardized physical examinations were conducted to measure height and weight, and overweight and obesity were defined according to the Screening for Overweight and Obesity among School age Children and Adolescents. Multivariable Logistic regression model was used to examine the association between the home food environment and overweight and obesity among primary school students.
Results:
Characteristics of the home food environment showed that "healthy cooking and seasoning" was the predominant household cooking pattern among primary school students, accounting for 2 119 students (57.7%), whereas "unhealthy cooking and seasoning" accounted for the lowest proportion, with 37 students(1.0%). Among households, the proportions of "often/always" available unhealthy foods were relatively high for candies(22.6%) and sugar sweetened beverages(19.2%). The mean score for household availability of unhealthy foods was (7.81±4.01). Multivariable Logistic regression analysis showed that, after adjustment for sex, age, family residence, and socioeconomic status, students from households with "unhealthy cooking and healthy seasoning" had a higher risk of overweight and obesity than those from households with "healthy cooking and seasoning" ( OR =1.60, 95% CI =1.03-2.46), the risk was even higher among students from households with "unhealthy cooking and seasoning" ( OR = 3.99 , 95% CI =2.03-7.86) (both P <0.05). Household availability of unhealthy foods was positively associated with overweight and obesity among primary school students. Each one point increase in the unhealthy food availability score was associated with a 7% increase in the risk of overweight and obesity ( OR =1.07, 95% CI =1.01-1.13); in addition, students from households where sugar sweetened beverages were "often/always" available had an increased risk of overweight and obesity ( OR=1.40, 95%CI =1.07- 1.86 ) (both P <0.05).
Conclusions
The home food environment is associated with the risk of overweight and obesity among primary school students. Improving household cooking practices and controlling the availability of unhealthy foods at home may contribute to the prevention and control of overweight and obesity among primary school students.

With the aging population and the widespread implementation of lung cancer screening programs, an increasing number of elderly patients are undergoing curative lung resection. Due to diminished physiological reserve and complex comorbidities, this demographic exhibits a significantly higher incidence of severe perioperative complications (defined as Clavien-Dindo grade≥Ⅲ), which adversely affects both perioperative safety and long-term prognosis. In recent years, the research paradigm has shifted from univariate analysis toward multidimensional risk integration and the development of predictive models. This article systematically reviews the key risk factors for severe perioperative complications in elderly lung cancer patients, encompassing biological aging processes, frailty and sarcopenia, cardiopulmonary and renal functional reserves, inflammatory-immune and coagulation status, and perioperative interventions. Furthermore, it traces the evolution of risk assessment tools from traditional regression models to machine learning models that integrate multimodal data. The review also discusses common challenges in this field, including the standardization of outcome definitions, external validation, calibration assessment, and clinical translation. Future efforts should prioritize the deep integration of predictive tools with clinical decision support systems to establish a closed-loop care pathway from risk identification to stratified intervention, thereby effectively reducing complication rates and enhancing surgical outcomes for elderly lung cancer patients.

Morinda officinalis is one of the “Four Great Southern Medicines” and is commonly used in clinical practice to treat erectile dysfunction and nocturnal emissions caused by kidney yang deficiency, uterine cold infertility, menstrual disorders, low abdominal pain, rheumatism, and muscle and bone weakness. Based on the principle of “treating raw and cooked differently”, this article summarizes the effects of different processing methods on the chemical constituents and pharmacological effects of M. officinalis . Research has found that processing can affect the content and structure of sugars, iridoids, and anthraquinones in M. officinalis , thereby regulating its pharmacological effects such as anti-osteoporosis, immune regulation, anti-fatigue, and anti-depression. Among them, salt M. officinalis shows outstanding performance in anti-osteoporosis and enhancing immunity. Although previous studies have preliminarily elucidated the major chemical constituents of M. officinalis and their pharmacological characteristics, the dynamic transformation paths of constituents during the processing remain to be further clarified, especially the es tablishment of a quality marker system associated with the processing technology, to achieve the precision and intelligent development of the processing.

Objective To investigate the effect of tritiated water on the immune system of zebrafish and its potential molecular mechanism. Methods Zebrafish embryos (2.5 to 3 hours post-fertilization [hpf]) were exposed to 3.7 × 104 Bq/mL tritiated water (tritiated water group), and those exposed to E3 culture medium were used as the control group. The mortality rate, hatching rate, deformity rate, heart rate, body length, yolk sac area, neutrophil count in the tail, immune-related gene expression, and immune-related protein expression of zebrafish in the two groups were determined. Then transcriptome technology was used to further analyze the possible mechanism of tritiated water affecting the immune system of zebrafish. Results Compared with the control group, zebrafish at 72 hpf in the tritiated water group had no significant changes in the mortality rate, hatching rate, deformity rate, body length, and yolk sac area((t = 0.9045, 0.5000, 1.0000, 0.7238, 0.0337, P = 0.4169, 0.6433, 0.3739, 0.4785, 0.9735), but had significantly increased heart rate(t = 4.575,P = 0.002). At 4 days post-fertilization (dpf), the neutrophil count in the tail of zebrafish in the tritiated water group was significantly increased(t = 2.563,P = 0.0196), the mRNA expression of TNF-α was significantly decreased(t = 2.891, P = 0.045), the protein expression of nuclear factor-kappa B (NF-κB) was significantly increased(t = 3.848, P = 0.018), and the protein expression of NLRP3 was significantly decreased(t = 14.98, P = 0.001). At 7 dpf, the neutrophil count in the tail and the protein expression levels of NF-κB, NLRP3, and interleukin-1β were significantly decreased(t = 3.772, 7.048, 15.620, 4.423, P = 0.014, 0.002, 0.0001, 0.012). Transcriptome sequencing revealed that differentially expressed genes were mainly enriched in the “neutrophil activation” and “platelet activation pathways” at 4 dpf and in the “neutrophil apoptosis”, “ferroptosis”, and “necroptosis” pathways at 7 dpf. Conclusion Tritiated water exposure induces a temporally dynamic immune response in zebrafish, potentially affecting immune homeostasis by regulating neutrophil activation and apoptosis, as well as the expression of NF-κB and NLRP3.

Objective To investigate the sputum metabolic profiles of patients with occupational coal workers' pneumoconiosis (CWP) by an untargeted metabolomics method, and to identify relevant differential metabolic pathways and potential biomarkers. Methods A total of 12 male patients with stage Ⅰ CWP were selected as the CWP group, and 16 healthy male individuals were selected as the control group, using a judgmental sampling method. Sputum metabolites of individuals in both groups were detected to perform non-targeted metabolomic analysis using the ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. Differential metabolites (DMs) and their pathways were screened using principal component analysis, partial least squares discriminant analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Potential biomarkers were analyzed and identified via the receiver operating characteristic curve (ROC). Results There were apparent metabolic alterations observed in sputum of CWP patients compared with healthy controls. In the positive ion mode, a total of 42 DMs were identified in sputum from CWP patients, including 19 downregulated and 23 upregulated metabolites. In the negative ion mode, a total of 25 DMs were identified in sputum from CWP patients, including 16 downregulated and 9 upregulated metabolites. KEGG enrichment analysis of sputum from CWP patients showed that seven DMs pathways were enriched in ABC transporters, histidine metabolism, phenylalanine metabolism, arachidonic acid metabolism, linoleic acid metabolism, purine metabolism, and oxidative phosphorylation, involving 26 DMs. ROC analysis indicated that 16(R)-hydroxyarachidonic acid, pyrophosphate, and 2-hydroxyphenylacetate of these 26 DMs may serve as potential biomarkers for CWP. Conclusion Sputum metabolomic profiles were altered in CWP patients compared with healthy controls. The potential biomarkers of CWP prevention and treatment are 16(R)-hydroxyarachidonic acid, pyrophosphate, and 2-hydroxyphenylacetate.
