ObjectiveTo investigate the epidemiological characteristics and influencing factors of depressive symptoms among middle school (junior, senior, and vocational high school) students in Yunnan Province, China, and to inform evidence-based intervention strategies for adolescent mental health. MethodsA cross-sectional survey was conducted between October and November 2023 using stratified random cluster sampling. Students from eight counties (districts) across four prefectures (cities) in Yunnan Province were included. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Multivariate logistic regression analysis was performed to examine factors associated with depressive symptoms, with stratified analyses conducted by gender, educational stage, and ethnicity. ResultsA total of 4 672 questionnaires were distributed, with 4 670 valid questionnaires retrieved, yielding a valid response rate of 99.96%. The surveyed participants were predominantly female students (50.81%), junior high school students (49.13%), ethnic minorities (52.78%), and urban residents (79.29%). The mean CES-D score for middle school students in Yunnan Province was (15.31±10.83). Female students had a significantly higher mean score (16.63±11.41) than male students (13.95±10.02) (P<0.001). Senior high school students had a significantly higher mean score (16.61±10.61) compared to both junior high school students (14.74±11.45) and vocational high school students (13.10±7.71) (all pairwise comparisons P<0.001). The prevalence of depressive symptoms among middle school students in Yunnan Province was 28.18%. The prevalence was significantly higher in females (34.09%) than in males (22.07%). By school type, the detection rate was highest among senior high school students (33.39%), followed by junior high school students (26.29%) and vocational high school students (17.27%) (P<0.05). Multivariate logistic regression analysis showed that female gender (OR=2.16, 95%CI: 1.86‒2.50), being in junior high school (OR=2.43, 95%CI: 1.84‒3.20) or senior high school (OR=2.27, 95%CI: 1.73‒2.98), not living with parents (OR=1.24, 95%CI: 1.07‒1.44), irregular breakfast consumption (OR=1.52, 95%CI: 1.33‒1.75), lack of moderate-to-vigorous physical activity (MVPA) (OR=1.69, 95%CI: 1.37‒2.09), sleep duration ≤5 h per night (OR=2.52, 95%CI: 2.02‒3.14) or 6‒7 h per night (OR=1.47, 95%CI: 1.25‒1.73), smoking (OR=1.86, 95%CI: 1.56‒2.23), and alcohol consumption (OR=1.81, 95%CI: 1.54‒2.13) were positively associated with depressive symptoms. In contrast, screen time ≤1 h (OR=0.71, 95%CI: 0.59‒0.86) was negatively associated with depressive symptoms. Stratified analyses showed that female students not living with parents (OR=1.29, 95%CI: 1.06‒1.58), senior high school students (OR=1.51, 95%CI: 1.21‒1.88), and Han Chinese students (OR=1.37, 95%CI: 1.11‒1.69) were more likely to experience depressive symptoms. Han Chinese students who smoked were also more likely to have depressive symptoms (OR=1.72, 95%CI: 1.34‒2.21). In contrast, male students with screen time ≤1 h (OR=0.71, 95%CI: 0.53‒0.95) and ethnic minority students (OR=0.74, 95%CI: 0.58‒0.95) were less likely to experience depressive symptoms. Regardless of gender, irregular breakfast consumption, lack of MVPA, sleep duration less than 8 h per night, smoking, and alcohol consumption were all positively associated with depressive symptoms (P<0.05). Among both junior and senior high school students, irregular breakfast consumption, lack of MVPA, smoking, and alcohol consumption were positively associated with depressive symptoms (all P<0.05), while screen time ≤1 h was negatively associated with depressive symptoms (all P<0.05). For junior high school students, engaging in 1‒2 days of MVPA per week, screen time more than 2 h per day, and sleep duration 6‒7 h per night were all positively associated with depressive symptoms (all P<0.05). Among junior high, senior high, and vocational high school students, sleep duration ≤5 h per night was positively associated with depressive symptoms (P<0.05). For both Han Chinese and ethnic minority students, irregular breakfast consumption, lack of MVPA, sleep duration less than 8 h per night, and alcohol consumption were all positively associated with depressive symptoms (all P<0.05). ConclusionThe prevalence of depressive symptoms among middle school students in Yunnan Province is comparable to that in central China and higher than that in northern regions. Prevention and control efforts should prioritize female students and those in junior and senior high school stages. Universal improvements in lifestyle behaviors among middle school students, such as regular breakfast consumption, MVPA, sufficient sleep (≥8 h), and abstinence from smoking and alcohol. Particular attention should be given to limiting excessive screen time among junior high school students and addressing the mental health needs of females not living with their parents, senior high school students, and Han Chinese students.

Mitochondrial quality control （MQC） homeostasis serves as a fundamental mechanism in maintaining the mitochondrial structure and function. Dysregulation of MQC contributes to the progression of acute ischemic stroke （AIS） through multiple pathways including disturbances in energy metabolism， increased oxidative stress， and imbalances in mitochondrial fusion and fission. Drawing upon the traditional Chinese medicine （TCM） theory of the kidney governing Yin and Yang， this study innovatively proposes an integrative model of "Yin-Yang dynamic balance-MQC homeostasis" to elucidate the underlying pathophysiological mechanisms. Specifically， kidney Yang deficiency and decline result in reduced driving force， thereby inhibiting mitochondrial fusion. This leads to decreased efficiency of oxidative phosphorylation and impaired adenosine triphosphate （ATP） production. Conversely， when kidney Yin is dysfunctional and excessive phlegm-blood stasis accumulates， mitochondrial fission becomes hyperactive， causing rapid accumulation of reactive oxygen species （ROS） and intensified oxidative stress. The interplay between these two pathological states culminates in the central TCM pathogenesis—Yin-Yang imbalance and disordered Qi and blood-of AIS. To address this pathogenesis， a therapeutic strategy is proposed： tonifying the kidney as the primary intervention to restore MQC homeostasis， supplemented by resolving phlegm and removing blood stasis to interrupt the deleterious cycle of cerebral vascular damage. This work integrates the holistic perspective of TCM with contemporary molecular insights， offering precise intervention targets along the "kidney-mitochondria axis" for the prevention and treatment of AIS， while establishing a novel integrative paradigm for stroke management that bridges traditional and modern medicine. Future research should focus on elucidating the molecular mechanisms through which TCM regulates MQC in AIS and integrating classical TCM theories with evidence-based medicine to facilitate the translation of theoretical insights into clinical applications.

BACKGROUND:Peripheral nerve axon rupture seriously affects patients' physical function and mental health.Microsurgery,nerve autograft,nerve allograft,fibrin glue and catheter technology are the main treatments for peripheral nerve injury,each of which has its own advantages and disadvantages,but the overall treatment effect is not satisfactory.Despite the clinical success of Schwann cells in promoting axonal regeneration,there are still many challenges in the treatment with Schwann cells,such as slow expansion of Schwann cells,immune rejection,and low survival rate of transplanted cells.OBJECTIVE:To summarize the role and mechanism of Schwann cells in promoting the regeneration of peripheral nerve axons,and the difficulties and challenges of Schwann cells in the process of nerve regeneration treatment.METHODS:PubMed,Medline,WanFang,VIP,and CNKI were searched by computer using the search terms of"Schwann cells,synaptic Schwann cell,macrophage,peripheral nerve axon rupture,Wallerian degeneration,Peripheral nerve axon regeneration,Central nervous system repair"in English and Chinese.Literature related to Schwann cell proliferation and differentiation,promotion of peripheral nerve regeneration,and clinical applications was retrieved from database inception to October 2024,and a total of 95 articles were finally included for review.RESULTS AND CONCLUSION:Schwann cells interact with macrophages,T cells and other cells,to initiate the regeneration process through signaling pathways,including Krox20/C-Jun,NRG-1/ErbB,Notch,MAPK,and PI3K/Akt/mTOR,synthesize and release nerve growth factors,and thus promote regeneration of the peripheral nervous system.Schwann cells have been experimentally demonstrated to have great potential in peripheral nerve repair and are expected to become the key target of therapeutic intervention.However,there are still problems such as difficulties in cell harvest and culture,as well as the occurrence of other diseases during the treatment process.

Objective: To investigate the mechanism of Yishen Tongluo Formula in ameliorating renal pyroptosis in diabetic nephropathy mice by regulating the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-κB (NF-κB) signaling pathway. Methods: Sixty C57BL/6 male mice were randomly divided into control (10 mice) and intervention groups (50 mice) using random number table method. The diabetes nephropathy model was established by intraperitoneally injecting streptozotocin(50 mg/kg). After modeling, the intervention group was further divided into model, semaglutide (40 μg/kg), and high-, medium-, and low-dose Yishen Tongluo Formula groups (15.6, 7.8, and 3.9 g/kg, respectively) using random number table method. The high-, medium-, and low-dose Yishen Tongluo Formula groups were administered corresponding doses of medication by gavage, the semaglutide group received a subcutaneous injection of semaglutide injection, and the control group and model groups were administered distilled water by gavage for 12 consecutive weeks. Random blood glucose levels of mice in each group were monitored, and the 24-h urinary protein content was measured using biochemical method every 4 weeks; after treatment, the serum creatinine and urea nitrogen levels were measured using biochemical method. The weight of the kidneys was measured, and the renal index was calculated. Hematoxylin and eosin, periodic acid-Schiff, periodic Schiff-methenamine, and Masson staining were used to observe the pathological changes in renal tissue. An enzyme-linked immunosorbent assay was used to detect urinary β2-microglobulin (β2-MG), neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) levels. Western blotting and real-time fluorescence PCR were used to detect the relative protein and mRNA expression levels of nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3), Caspase-1, gasdermin D (GSDMD), interleukin-1β (IL-1β), and interleukin-18 (IL-18) in renal tissue. Immunohistochemistry was used to detect the proportion of protein staining area of the TLR4, MyD88, and NF-κB in renal tissue. Results: Compared with the control group, the random blood glucose, 24-h urinary protein, serum creatinine, urea nitrogen, and renal index of the model group increased, and the urine β2-MG, NGAL, and KIM-1 levels increased. The relative protein and mRNA expression levels of NLRP3, Caspase-1, GSDMD, IL-1β, and IL-18 in renal tissue increased, and the proportion of TLR4, MyD88, and NF-κB protein positive staining areas increased (P<0.05). Pathological changes such as glomerular hypertrophy were observed in the renal tissue of the model group. Compared with the model group, the Yishen Tongluo Formula high-dose group showed a decrease in random blood glucose after 12 weeks of treatment (P<0.05). The Yishen Tongluo Formula high- and medium-dose groups showed a decrease in 24-h urinary protein, creatinine, urea nitrogen, and renal index, as well as decreased β2-MG, NGAL, and KIM-1 levels. NLRP3, Caspase-1, GSDMD, IL-1 β, and IL-18 relative protein and mRNA expression levels were also reduced, and the proportion of TLR4, MyD88, and NF-κB protein positive staining areas was reduced (P<0.05). Pathological damage to renal tissue was ameliorated. Conclusion Yishen Tongluo Formula may exert protective renal effects by inhibiting renal pyroptosis and alleviating tubular interstitial injury in diabetic nephropathy mice by regulating the TLR4/MyD88/NF-κB signaling pathway.

MethodsSpecific pathogen-free （SPF） male C57BL/6 mice were assigned into a control group （n=10） and a modeling group （n=50）. The DKD model was established by intraperitoneal injection of streptozotocin. The mice in the modeling group were randomized into a model group， a semaglutide （40 μg·kg^-1） group， and high-， medium-， and low-dose （18.2， 9.1， 4.55 g·kg^-1， respectively） Yishen Tongluo prescription groups， with 10 mice in each group. The treatment lasted for 12 weeks. Blood glucose and 24-h urine protein levels were measured， and the kidney index （KI） was calculated. Serum levels of creatinine （SCr）， blood urea nitrogen （BUN）， alanine aminotransferase （ALT）， and aspartate aminotransferase （AST） were assessed. The pathological changes in the renal tissue were evaluated by hematoxylin-eosin， periodic acid-Schiff， periodic acid-silver methenamine， and Masson’s trichrome staining. Enzyme-linked immunosorbent assay kits were used to measure the levels of β2-microglobulin （β2-MG）， neutrophil gelatinase-associated lipocalin （NGAL）， kidney injury molecule-1 （KIM-1）， liver fatty acid-binding protein （L-FABP）， nitric oxide synthase （NOS）， glutathione （GSH）， total antioxidant capacity （T-AOC）， and 8-hydroxy-2'-deoxyguanosine （8-OHdG）. Immunohistochemical staining was performed to examine the expression of Kelch-like ECH-associated protein 1 （Keap1） and malondialdehyde （MDA）. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR） and Western blot were employed to determine the mRNA and protein levels， respectively， of factors in the Nrf2/HO-1/NQO1 signaling pathway. ResultsCompared with the control group， the DKD model group showed rises in blood glucose， 24-h urine protein， KI， SCr， BUN， and ALT levels， along with glomerular hypertrophy， renal tubular dilation， thickened basement membrane， mesangial expansion， and collagen deposition. Additionally， the model group showed elevated levels of β2-MG， NGAL， KIM-1， L-FABP， NOS， and 8-OHdG， lowered levels of GSH and T-AOC， up-regulated expression of MDA and Keap1， and down-regulated expression of Nrf2， HO-1， NQO1， and glutamate-cysteine ligase catalytic subunit （GCLC） （P<0.05）. Compared with the model group， the semaglutide group and the medium- and high-dose Yishen Tongluo prescription groups showed reductions in blood glucose， 24-h urine protein， KI， SCr， BUN， and ALT levels， along with alleviated pathological injuries in the renal tissue. In addition， the three groups showed lowered levels of β2-MG， NGAL， KIM-1， L-FABP， NOS， and 8-OHdG， elevated levels of GSH and T-AOC， down-regulated expression of MDA and Keap1， and up-regulated expression of Nrf2， HO-1， NQO1， and GCLC （P<0.05）. ConclusionYishen Tongluo prescription exerts renoprotective effects in the mouse model of DKD by modulating the Nrf2/HO-1/NQO1 signaling pathway， mitigating oxidative stress， and reducing renal tubular injuries.

Background Automotive repair workers are exposed to a wide variety of volatile organic compounds (VOCs) during painting operations, which poses significant health risks. Biomonitoring can directly reflect the internal body burden of these compounds. Therefore, it is essential to develop an analytical method for simultaneous determination of VOCs in the urine of automotive spray painting workers. Objective To establish a static headspace gas chromatography-mass spectrometry (GC-MS) method for simultaneously determining 22 VOCs in the urine of spray painting workers in automotive repair enterprises. Methods An automatic headspace sampler was used for the pretreatment of urine samples. The headspace conditions as well as the chromatographic and mass spectrometric conditions of static headspace GC-MS were optimized. The separation of 22 VOCs was achieved by optimizing the temperature program. Sensitivity was enhanced by optimizing the quantitative ions. The signal response of VOCs was improved by optimizing the headspace equilibrium temperature, equilibrium time, and the amount of inorganic salt added. The method's detection limit, lower limit of quantification, accuracy, precision, and stability were tested using blank urine samples spiked with standards. Additionally, the method was applied to examine 40 urine samples collected from painting workers in automotive repair enterprises in Tianjin. Results In this study, the headspace equilibrium temperature was set at 80 ℃, the equilibrium time was 30 min, and the salt addition amount was 2.0 g. A DB-624ms chromatographic column was selected for the separation of 22 VOCs. The initial temperature of heating program was 50 ℃, maintained for 15 min, and then increased to 85 ℃ at a heating rate of 10 ℃·min⁻¹ for 10 min, followed by increasing to 90 ℃ at a heating rate of 5 ℃·min⁻¹ for 20 min. The single ion monitoring (SIM) mode was chosen for the quantitative analysis of the 22 VOCs. The method demonstrated good linearity for determining 22 target analytes in the urine of spray painting workers, with correlation coefficients all above 0.990. The lower limits of quantification (LOQ) for the components ranged from 0.4 to 3.8 μg·L⁻¹. The spiked recovery rates of the samples were between 80.1% and 112.1%, and the relative standard deviations (RSD) ranged from 1.5% to 9.7%. All target analytes could be stored at 4 ℃ for 5 d and at −20 ℃ for 7 d. This method was applied to evaluate urine samples from 40 spray painting workers in automotive repair enterprises in Tianjin. The positive rate of butyl acetate was 37.5%. The positive rate of xylene was 32.5%. The positive rate of toluene was 30.0%. The positive rate of isopropanol was 25.0%. The concentration range of the detected substances was from −1. Conclusion The established simultaneous determination protocol of 22 VOCs by static headspace- GC-MS is characterized by its simplicity, high sensitivity, excellent selectivity, and high accuracy. It is suitable for urine samples of spray painting workers in automotive repair industry.

Background Currently, incidents of organic solvent poisoning are occurring frequently. Rapidly and accurately qualitative and quantitative analysis of toxic substances is crucial for the treatment of affected individuals. In recent years, many biomarker assays with good specificity and high sensitivity have been developed for the detection of exposure to organic solvents, but they cannot meet the demand for real-time and fast detection. Objective To establish a paper spray mass spectrometry method for direct and rapid detection of four organic compound metabolites (toluene diamine, 2,5-hexanedione, hippuric acid, and methylhippuric acid) in the urine of occupational populations. Methods Toluene diamine and 2,5-hexanedione were analyzed using positive ion mode, while hippuric acid and methylhippuric acid were analyzed using negative ion mode. The ion transfer tube temperature was 275 °C. The ion transfer tube voltage was 35 V. For positive ion mode, the scan range was 50-150 m/z. For negative ion mode, the scan range was 150-250 m/z. The distance from the paper substrate tip to the mass spectrometry inlet was 8 mm. The applied voltage was 3.5 kV. The spray solvent was methanol/water (90:10). The spray solvent volume was 15 μL. Under the optimized experimental conditions, both external standard and internal standard methods were used for quantitative analysis. Limit of detection, limit of quantification, accuracy, and precision of the proposed method were determined by spiking blank urine samples. To evaluate the feasibility of the method, the established approach was compared with current national standard detection methods or methods described in the literature. All methods were used to analyze 40 urine samples collected from occupationally exposed individuals (20 exposed to n-hexane and 20 exposed to toluene and xylene). Results The four biomarkers showed good linearity within their respective measurement ranges and the correlation coefficients were higher than 0.9990. The limits of detection of the method were in the range of 0.00027 to 0.020 μg·mL⁻¹, and the limits of quantification were in the range of 0.0009 to 0.067 μg·mL⁻¹. The spiked recoveries at low, medium, and high concentrations ranged from 96.5% to 106.9%, with relative standard deviations (RSDs) between 5.6% and 9.7%. When applying the method to 40 urine samples from occupationally exposed individuals, the detection rates for toluene diamine, 2,5-hexanedione, hippuric acid, and methylhippuric acid were 0%, 45%, 20%, and 37.5%, respectively. For biomarkers detected by both this method and the reference methods, the detection values were generally consistent. The analysis time per sample was approximately 1-2 min using paper spray mass spectrometry, compared to 1-2 h for reference methods. Conclusion The paper spray mass spectrometry method established in this study for detecting four organic compound metabolites in urine is characterized by its simplicity, rapidity, efficiency, and high accuracy. It can obtain results within 1-2 min, which significantly improves the timeliness of detection. It is suitable for direct and rapid screening of four organic compound metabolites in urine, and can provide technical support for the diagnosis and treatment of organic solution poisoning.

OBJECTIVES: Intracranial aneurysm (IA) has an insidious onset, and once ruptured, it carries high rates of mortality and disability. Cardiometabolic factors may be associated with the formation and rupture of IA. This study aims to summarize the application of Mendelian randomization (MR) methods in research on cardiometabolic factors and IA, providing insights for further elucidation of IA etiology and pathogenesis. METHODS: Literature about MR-based IA studies published up to February 21, 2024, was retrieved from PubMed, Embase, Web of Science, CNKI, and Wanfang. Two researchers independently performed literature screening, data extraction, and quality assessment. A narrative synthesis approach was used to conduct a qualitative systematic review of the included studies. RESULTS: A total of 11 MR-based studies on IA published between 2017 to 2024 were included, of which 4 were rated as high quality. These studies investigated the associations between blood pressure, blood lipids, blood glucose, obesity-related indicators, and inflammatory cytokines with IA and its subtypes, though issues of duplication were noted. Four MR studies based on the same European population but using different instrumental variable selection criteria, as well as another MR study in a different European cohort, consistently identified blood pressure as a risk factor for IA and its subtypes. Findings for blood lipids, blood glucose, obesity-related indicators, and inflammatory cytokines were inconsistent across MR studies. CONCLUSIONS Blood pressure appears to increase the risk of IA and its subtypes. Associations between other cardiometabolic factors and IA/subtypes require further in-depth investigation. Given the inherent limitations of MR studies, causal inferences should be made cautiously in combination with other lines of evidence.
