ObjectiveTo explore the possible mechanisms by which ligustilide (LIG) exerts neuroprotective effects on ischemic stroke (IS) by inhibiting the release of neutrophil extracellular traps (NETs), promoting blood-brain barrier repair, and alleviating post-ischemic neuroinflammation, thereby providing a new direction for IS treatment. MethodsA middle cerebral artery occlusion (MCAO) model was established in rats. The rats were divided into the sham operation (Sham) group, model (Model) group, low- and high-dose LIG groups (20, 40 mg·kg-1), and the NET inhibitor CI-amidine group (CI-amidine, 10 mg·kg-1). Drug treatments were administered for 3 days. Neurological injury after ischemia was evaluated by 2,3,5-triphenyltetrazolium chloride (TTC) staining, neurological deficit scoring, and brain index measurement. Flow cytometry and Western blot were used to analyze changes in neutrophil expression. Immunofluorescence was used to observe the fluorescence intensity of the NET marker citrullinated histone H3 (H3Cit). Western blot was performed to detect the expression of blood-brain barrier tight junction-related proteins and inflammatory factors, including interleukin-18 (IL-18) and interleukin-1β (IL-1β). ResultsCompared with the Sham group, the Model group exhibited significant brain tissue injury (P<0.05), significantly increased neutrophil numbers and NET expression (P<0.05), significantly impaired blood-brain barrier permeability (P<0.05), and significantly increased expression of inflammatory factors (P<0.05). Compared with the Model group, both low- and high-dose LIG significantly alleviated brain tissue injury in rats (P<0.01), inhibited neutrophil numbers and NET expression (P<0.01), reduced blood-brain barrier damage (P<0.01), and suppressed the expression of inflammatory factors IL-18 and IL-1β (P<0.01), thereby ultimately exerting a neuroprotective effect. ConclusionThe neuroprotective effect of LIG in rats with cerebral ischemia-reperfusion injury may be related to inhibition of neutrophils and the NETs induced by them.

ObjectiveThis paper aims to investigate the protective effects of the Tanyu Tongzhi Youhua prescription(TYTZP) against myocardial ischemia/reperfusion injury in rats via regulation of the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) signaling pathway. MethodsFifty-six 8-week-old male Sprague-Dawley (SD) rats were randomly divided into sham group, model group, ticagrelor group (32.4 mg·kg-1), RU320521 (RU.521cGAS inhibitors) group (5 mL·kg-1), groups of TYTZP with low dose (3.6 g·kg-1), medium dose (7.2 g·kg-1), and high dose (14.4 g·kg-1), with eight rats per group. The ticagrelor group and groups of TYTZP with different doses received pre-treatment for seven days according to their respective protocols. The RU.521 group received an intraperitoneal injection one hour before modeling. A rat model of the no-reflow phenomenon in myocardial ischemia/reperfusion injury was established by ligating the left anterior descending coronary artery in situ. Myocardial no-reflow area was determined by thioflavin staining. Histopathological morphology of myocardial tissue was observed via hematoxylin and eosin (HE) staining. Cardiac function was detected by echocardiography. Myocardial microcirculation function change was observed by using real-time myocardial contrast echocardiography. The myocardial enzyme levels in the serum were measured by serum biochemical analysis. The double-stranded DNA (dsDNA) levels were detected by using PicoGreen. The protein expression of cGAS, STING, and nuclear factor-κB (NF-κB) p65 in myocardial tissue was detected by Western blot. The levels of cardiac troponin Ⅰ (cTNⅠ), cardiac troponin T (cTNT), interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) in the peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the sham group, the model group showed a significantly increased myocardial no-reflow area (P<0.01). Myocardial fiber rupture and disarray and inflammatory cell infiltration were observed by HE staining. The ultrasound results indicated that left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) (P<0.01) were significantly decreased. Real-time myocardial contrast echocardiography showed that the peak time of myocardial blood perfusion was significantly prolonged (P<0.01), and the levels of creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH), cTNⅠ, cTNT, and dsDNA were significantly elevated (P<0.01). Western blot results showed that the myocardial protein expressions of cGAS, STING, and NF-κB p65 were upregulated (P<0.01). ELISA results showed that the inflammatory factors in the serum such as IL-6, IL-1β, and TNF-α were increased (P<0.01). Compared with the model group, the group of the TYTZP significantly reduced the levels of myocardial enzyme, troponins, and dsDNA (P<0.01, P<0.05), improved cardiac function and myocardial microcirculation, alleviated histopathological morphology and inflammatory infiltration, inhibited activation of the cGAS/STING pathway, reduced the expression of NF-κB p65 (P<0.01, P<0.05), and inhibited inflammatory response. ConclusionThe TYTZP mitigates the no-reflow phenomenon in myocardial ischemia/reperfusion injury, and its mechanism is associated with inhibiting the activation of the cGAS/STING pathway and attenuating inflammatory responses.

Background Depressive symptoms have become a significant factor affecting the physical and mental health of the occupational population, and workers in petroleum refining enterprises face multiple stressors in their work environment. Objective To explore the impact of occupational noise exposure on depressive symptoms among workers in a petroleum refining enterprise. Methods This cross-sectional study was conducted in July 2024 using a questionnaire survey among workers of a petroleum refining enterprise in Hainan Province. Basic information of the subjects was collected. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to measure depressive symptoms, the Chinese version of the Pittsburgh Sleep Quality Index (PSQI) scale was used to assess sleep quality, and the Chinese version of the Effort-Reward Imbalance (ERI) scale was used to evaluate occupational stress. Chi-square test was employed to compare the differences in reporting depressive symptoms among populations with different characteristics. Binary logistic regression models were used to analyze the impact of occupational noise exposure and other factors on depressive symptoms. Results The overall positive rate of depressive symptoms in the study population was 42.7%. The results of the multifactor analysis indicated that compared with the control group, employees in both the low-exposure and high-exposure groups had elevated odds of depressive symptoms, with OR (95%CI) of 2.244 (1.131, 4.454) and 1.970 (1.009, 3.850), respectively. This association remained robust after adjusting for potential confounders, including gender, age, work tenure, and other occupational exposures. Additionally, female [OR (95%CI)=1.483 (1.039, 2.118)], exposure to benzene, toluene, or xylene [OR (95%CI)=1.621 (1.208, 2.174)], sleep disturbance [OR (95%CI)=3.772 (2.942, 4.838)], and occupational stress [OR (95%CI)=2.018 (1.575, 2.585)] were also significantly associated with higher odds of depressive symptoms. Conclusion The positive rate of depressive symptoms is relatively high among employees in this petrochemical enterprise, and occupational noise exposure may be a risk factor for depressive symptoms.

Acquired paralytic strabismus is a common neuromuscular disorder in adults,characterized by diplopia, visual confusion, impaired ocular motility, and ocular deviation, which severely affects the patient's quality of life and overall health. The disease has a complex etiology, encompassing multiple pathological mechanisms such as vascular pathologies, trauma, inflammation, neoplasms, and immune-related disorders. Treatment primarily focuses on addressing the underlying cause. While conventional Western approaches, such as medication and surgery, can alleviate symptoms, some carry the risk of adverse effects, and their long-term recurrence rates warrant careful consideration. Traditional Chinese medicine utilizes distinctive therapies such as herbal medicine, acupuncture, and other adjunctive therapies, which have shown promising therapeutic effects but are constrained by a lack of high-quality evidence from large-scale randomized controlled trials. This review systematically summarizes recent advances in the etiological classification and traditional Chinese and Western medical treatments of acquired paralytic strabismus. It innovatively summarizes the clinical features associated with different causes, analyzes current therapeutic strategies and research landscape, aiming to inform clinical practice and suggest future research directions.

Objective:
To explore the latent classes of peer victimization among junior high school students, and to analyze the association between the characteristics of different classes and non suicidal self injury(NSSI) behavior,so as to provide scientific basis for the prevention and intervention of NSSI behavior among junior high school students.
Methods:
A census method was used to select 19 738 students from 16 junior high schools in a central urban area of Wuhan as research subjects from November to December 2024. The Multidimensional Peer Victimization Scale and a self designed NSSI questionnaire were used to assess peer victimization and NSSI behaviors. Latent profile analysis (LPA) was used to identify latent classes of peer victimization among students by sex. Binary Logistic regression model was used to analyze the association between latent classes of peer victimization and NSSI behavior among junior high school students of different genders.
Results:
Latent patterns of peer victimization among boys were classified into 4 groups:no victimization group (85.8%, n =8 874), low victimization-verbal type group (6.6%, n =682), low victimization-mixed type group (5.7%, n =587) and high victimization group (1.9%, n =195); girls were classified into 4 groups:no victimization group (87.0%, n =8 179), low victimization group (7.5%, n =702), high victimization-social type group (3.8%, n =360) and high victimization-physical type group (1.7%, n =159). After controlling for only child status, place of residence, parenting style, and self rated family socioeconomic status, binary Logistic regression analysis showed that the risk of NSSI behavior among boys increased sequentially in the low victimization-verbal type group( OR =4.14, 95% CI =3.22-5.31), low victimization-mixed type group ( OR =4.75, 95% CI =3.68-6.13), and high victimization group ( OR =8.26, 95% CI =5.83-11.71) compared to the no victimization group; the risks of NSSI behavior among girls increased sequentially in the low victimization group ( OR =3.06, 95% CI = 2.51-3.72), high victimization-social type group ( OR =4.01, 95% CI =3.13-5.15), and high victimization-physical type group ( OR =6.18, 95% CI =4.38-8.73) compared to the no victimization group (all P <0.05).
Conclusions
There are gender differences in the latent classes of peer victimization among junior high school students and the risk of NSSI behavior varies across different victimization classes. Targeted prevention and intervention should be implemented based on the gender of junior high school students and the characteristics of peer victimization students experience.

Chronic obstructive pulmonary disease (COPD) is the most common chronic respiratory disease around the world, and pharmacotherapy is the foremost treatment method currently. In recent decades, with the rapid development of bronchoscopic interventional therapy, endoscopic physical ablation technology presents a therapeutic effect in treating COPD, with few treatment-related side effects, showing excellent application prospects in treating COPD. Since ablation techniques in this field are emerging technologies with low patient acceptance, they are not widely used in the clinical treatment of COPD. This article reviews the development process of physical ablation techniques. Moreover, their current application status and the prospects in the field of COPD treatment are also summarized and analyzed. We hope to promote the application of physical ablation in the clinical treatment of COPD and provide practical references and a theoretical basis for the clinical treatment of COPD.
9.Analysis of knowledge awareness and associated factors of chikungunya fever among medical college students in Baise City
Chinese Journal of School Health 2026;47(3):347-350
Objective:
To understand the awareness of chikungunya fever knowledge and its related factors among medical college students in Baise City, so as to provide a scientific basis to offer relevant courses and special education.
Methods:
From July to August 2025, 7 286 enrolled medical students were selected by a sampling method from a medical college in Baise City to participate in the questionnaire survey. The questionnaire covered epidemiological characteristics, clinical symptoms, and prevention/control knowledge of chikungunya fever. Statistical analyses including the Chi quare test and multivariate Logistic regression models were performed.
Results:
The overall awareness rate of chikungunya fever knowledge among the medical students was 18.89%. Among the knowledge items, the awareness rate of "the high incidence season" was the highest (84.05%), while that of "the infectious period" was the lowest (17.80%). Multivariate Logistic regression analysis showed that medical students with female (a OR= 1.37 , 95%CI =1.20- 1.57 ), the age for over 25 years old (a OR=1.76, 95%CI =1.05-2.93), whose father had a middle school educational level (a OR=1.18, 95%CI =1.05-1.31), and majored in preventive medicine (a OR=1.54, 95%CI =1.10-1.67) had relatively higher awareness rates of chikungunya fever knowledge (all P <0.05). In contrast, students of Zhuang ethnicity (a OR= 0.87 , 95%CI =0.76-0.98) and majoring in nursing (a OR=0.74, 95%CI =0.61-0.91) or pharmacy (a OR=0.70, 95%CI =0.52-0.95) had relatively lower awareness rates (all P <0.05).
Conclusions
The awareness rate of chikungunya fever related knowledge among medical college students in Baise City is relatively low. Schools should take targeted publicity measures to improve medical students awareness.

ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory, Qijia Rougan prescription, combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted, and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis (CHB-HF) who met the diagnosis and inclusion criteria were randomly assigned to an observation group (Qijia Rougan prescription + entecavir) and a control group (entecavir). The treatment duration was 24 weeks. Liver stiffness measurement (LSM), fibrosis-4 index (FIB-4), portal vein diameter, hepatitis B serology, biochemical indicators, hepatic fibrosis markers in serum [hyaluronic acid (HA), laminin (LN), procollagen Ⅲ peptide (PⅢP), and type Ⅳ collagen (Ⅳ-C)], and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis, with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment, the observation group showed a significant reduction in LSM and FIB-4 (P<0.01), as well as notable improvements in LN, Ⅳ-C, and various TCM syndrome scores (P<0.05, P<0.01). When compared to the control group after treatment, the observation group demonstrated significant improvements in LSM, FIB-4, and various TCM syndrome score indicators (P<0.05, P<0.01), indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment, the observation group had better improvement in regression of stages F2 and F3 (P<0.05). When compared to the control group after treatment, the observation group exhibited superior improvement in regression of stage F3 (P<0.05). No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone, the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3, which is a potential “interception” point of the “Zhu Ke Jiao” theory.
