ObjectiveTo investigate whether Huanglian Jiedutang can inhibit neutrophil infiltration in the brains of middle cerebral artery occlusion (MCAO) mice by regulating the expression of neutrophil-related chemokines in exosomes, thereby achieving therapeutic effects. MethodsA total of 130 male specific pathogen-free (SPF) C57BL/6J mice were randomly divided into four groups: Sham-operated group, MCAO model group, Huanglian Jiedutang group (6 g·kg-1), and Ginaton group (21.6 mg·kg-1), with 10 mice in the Ginaton group and 40 mice in each of the remaining three groups. Mice in the Huanglian Jiedutang group and the Ginaton group were administered the corresponding drugs by oral gavage once daily at a volume of 0.15 mL·(10 g)-1 for 7 consecutive days, while the sham-operated and model groups received an equal volume of saline via the same route. After 7 days, MCAO surgery was performed. The distal and proximal ends of the right common carotid artery (CCA) were ligated, a small incision was made between the two ligatures, and a silicone rubber-coated monofilament with a rounded tip was inserted into the lumen to occlude the CCA. The filament was left in place for 1 h to establish a focal cerebral ischemia model. At 24 h after modeling, mice were evaluated. Neurological function was assessed using the Longa score. Cerebral infarct volume was measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Cerebral blood flow was observed by laser speckle imaging. Hematoxylin and eosin (HE) staining and Nissl staining were used to observe pathological changes in brain tissues. Exosomes were isolated from mouse plasma and brain tissues by ultracentrifugation and molecular size exclusion and identified by electron microscopy, particle size analysis, and protein blotting. Long-chain RNA libraries of exosomes were constructed and sequenced. Real-time quantitative reverse transcription polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of inflammatory factors and neutrophil-related chemokines in exosomes from plasma and brain tissues of each group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the protein expression of inflammatory factors and neutrophil-related chemokines in exosomes from brain tissues of each group. Immunohistochemistry was used to detect the expression of the neutrophil-specific protein myeloperoxidase (MPO) in the brains of mice in each group. ResultsCompared with the sham-operated group, the model group showed decreased neurological function scores (P<0.01), obvious cerebral infarction (P<0.01), reduced cerebral blood flow (P<0.01), neuronal necrosis in the brain, and decreased numbers of Nissl bodies (P<0.01). The mRNA expression levels of IL-1β, MPO, CXCL1, CXCL2, CXCL3, CXCL10, CCL2, and CCL3 in exosomes from plasma and brain tissues were significantly increased (P<0.05, P<0.01). The protein expression levels of IL-1β, MPO, CXCL2, and CXCL10 in exosomes from brain tissues were increased (P<0.05, P<0.01), and MPO-positive rates and mean optical density values in brain tissues were elevated (P<0.01). Compared with the model group, the Huanglian Jiedutang group and the Ginaton group showed increased neurological function scores (P<0.05), reduced cerebral infarct volume (P<0.01), restored cerebral blood flow (P<0.01), reduced necrotic cells in the brain, and increased numbers of Nissl bodies (P<0.01). In the Huanglian Jiedutang group, the mRNA expression levels of IL-1β, MPO, CXCL1, CXCL2, CXCL3, CXCL10, CCL2, and CCL3 in exosomes from plasma and brain tissues were decreased (P<0.05, P<0.01). The protein expression levels of IL-1β, MPO, CXCL2, and CXCL10 in exosomes from brain tissues were reduced (P<0.05, P<0.01), and MPO-positive rates and mean optical density values in brain tissues were decreased (P<0.01). ConclusionHuanglian Jiedutang can effectively regulate the expression of neutrophil-related chemokines in exosomes from plasma and brain tissues of MCAO mice, thereby reducing neutrophil infiltration in the brain and achieving therapeutic effects.

Chinese Journal of School Health 2026;47(3):398-402
Objective:
To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies.
Methods:
From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects.
Results:
Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05).
Conclusion
Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

ObjectiveTo explore the driving forces for oncology nurses’ participation in palliative care work, thereby providing a theoretical basis for the improvement of education and training, incentive mechanisms, and other aspects of the palliative care nursing staff. MethodsEmploying a qualitative research method, semi-structured interviews lasting 40-60 minutes were conducted with 14 nurses who had participated in palliative care work. The interview data were analyzed using the Colaizzi seven-step analysis method. ResultsInternal positive driving forces were job interest, empathy, and a sense of professional responsibility, while the negative was low psychological resilience. External positive driving forces included high work support, professional identity, mutual benefits for nurses and patients, and positive patient attitudes, whereas negative driving forces comprised busy routine clinical work, lack of a reward and incentive system, and bland or negative patient attitudes. ConclusionIt is essential to provide a flexible platform for the enhancement of nurses’ professional capabilities in palliative care, intensify the publicity of palliative care and death education; intervene and guide nurses’ negative emotions, improve and implement relevant incentive systems, and standardize the job recognition and scope of responsibilities of palliative care nurses.

Infection-related glomerulonephritis (IRGN) is an immune-mediated glomerular injury triggered by infectious agents. This article reports a case of immune complex-mediated glomerulonephritis following acute hepatitis B virus infection, which continued to progress despite standard antiviral and immunosuppressive therapy. Given the significant elevation of soluble complement membrane attack complex (sC5b-9), an indicator of terminal complement pathway activation, the patient was treated with eculizumab. Following treatment, the patient's urine protein-to-creatinine ratio significantly decreased, hypoalbuminemia and hematuria markedly improved, and sC5b-9 levels declined. This case suggests that abnormal complement system activation may be a key mechanism driving disease persistence in some patients with IRGN. For those unresponsive to conventional therapy, complement function screening and targeted terminal complement pathway inhibition may represent an effective salvage strategy.

OBJECTIVE To study the protective effect and potential mechanism of chikusetsu saponin Ⅳ a (chsⅣ) on renal function in diabetic nephropathy (DN) model rats. METHODS DN rat model was established by high-fat diet combined with streptozotocin injection. Thirty-six model rats were randomly divided into model group (i.g. administration of normal saline, high-fat diet), chsⅣ low-dose and high-dose groups (i.g. administration of 90, 180 mg/kg chsⅣ, high-fat diet), with 12 rats in each group. Additionally, 10 normal rats were set as the control group (i.g. administration of normal saline, regular diet). From the 5th to the 12th week after streptozotocin injection, they were given intragastric administration of relevant drug or normal saline, once a day. After the last medication, the levels of fasting blood glucose, fasting insulin, blood urea nitrogen, serum creatinine and urine protein as well as the levels of reduced glutathione (GSH), superoxide dismutase (SOD) and malondialdehyde (MDA) in renal tissues were measured. Additionally, the insulin resistance index was calculated. Hematoxylin-eosin, periodic acid-Schiff, and Masson staining techniques were employed to examine the histopathological alterations in the renal tissue. The expressions of Notch signaling pathway-related proteins in renal tissue were detected by immunohistochemical staining and Western blot methods. RESULTS Compared with model group, the histomorphological of renal tissues in the chsⅣ low- and high-dose groups were significantly improved, with significant decreases in renal histological scores, mesangial expansion index, and glomerulosclerosis scores ( P <0.05); the levels of fasting blood glucose, fasting insulin, blood urea nitrogen, serum creatinine, urine protein and homeostasis model assessment for insulin resistance, as well as MDA content, the expression levels of Notch1, Notch intracellular domain, hairy and enhancer of Split 1 and Delta-like protein 1 in renal tissue were all significantly decreased ( P <0.05). The levels of GSH and SOD in renal tissue were significantly elevated ( P <0.05). Moreover, the improvement in these indicators was significantly more pronounced in the chsⅣ high-dose group compared to the chsⅣ low-dose group ( P <0.05). CONCLUSIONS ChsⅣ can ameliorate renal pathological damage and functional impairment in DN rats. Its underlying mechanisms include restoration of glucose homeostasis and insulin sensitivity, attenuation of renal oxidative stress, and suppression of aberrant Notch signaling pathway activation.

Pulmonary fibrosis(PF) is a progressive and life-threatening disease with limited therapeutic options, highlighting the urgent need for innovative drug discovery strategies. To address this challenge, the authors propose the formula-originated rational intelligent screening&translation(FIRST), a systematic framework for developing anti-fibrotic monomers derived from classical traditional Chinese medicine(TCM). The strategy integrates three key dimensions, including tissue-oriented intelligent screening of active compounds, structural optimization based on drug-target spatial interactions and plant biosynthetic pathways, and cross-scale validation of drug. We further highlight its applications in discovering tissue-oriented novel drugs from clinically validated TCM, the development and mechanistic elucidation of anti-fibrotic therapeutics, as well as the clinical translation and secondary development of candidate drugs. This strategy paves the way for first-in-class, formula-derived monomeric drugs with defined structures, clarified mechanisms, and proven safety, offering a transformative avenue to meet the urgent therapeutic needs of PF and setting a new paradigm for TCM-based drug innovation.

OBJECTIVE To evaluate the efficacy of Compound glutamine enteric-coated capsules in the treatment and prevention of radiotherapy- and chemotherapy-related intestinal dysfunction in patients with malignant tumors. METHODS PubMed, Embase, CNKI, and Wanfang data were searched to collect randomized controlled trial (RCT) and cohort studies comparing Compound glutamine enteric-coated capsules (experimental group) with or without other treatments versus other treatments or blank control (control group). The search period was from the establishment of each database to November 19, 2025. After literature screening, data extraction, and quality assessment, a meta-analysis was performed using RevMan 5.4 software. RESULTS A total of 23 studies were included, involving 2 014 patients. Meta-analysis results showed that the effective rate in the experimental group was significantly higher than that in the control group, the overall incidence and moderate-to-severe incidence of radiotherapy- and chemotherapy-related intestinal dysfunction, quality of life scores, and interleukin-6 levels in the experimental group were significantly lower than those in the control group ( P <0.05). However, no statistically significant differences were observed between the two groups in terms of Karnofsky Performance Status score improvement rate and tumor necrosis factor-α levels ( P >0.05). The results of subgroup analysis based on different medications in the control group showed that, when used for treatment, regardless of whether patients in the control group received blank control or positive control, the efficacy in the experimental group was significantly higher than that in the control group ( P <0.05). When used for prevention, compared with patients who received blank control in the control group, the overall incidence and the incidence of moderate-to-severe radiotherapy- and chemotherapy-related intestinal dysfunction in the experimental group were significantly reduced ( P <0.05). No statistically significant difference was found in the overall incidence or incidences of moderate-to-severe radiotherapy- and chemotherapy-related intestinal dysfunction with positive control between the two groups ( P >0.05). CONCLUSIONS Compound glutamine enteric-coated capsules can effectively treat and prevent radiotherapy- and chemotherapy-related intestinal dysfunction in patients with malignant tumors, improve patients’ quality of life, and alleviate inflammatory responses.

AIM:To compare and analyze the effectiveness and safety of reducing the diameter of the back optical zone diameter(BOZD)of orthokeratology lens designed by CRT and VST in controlling the progression of myopia in children and adolescents.METHODS:Retrospective study. The study subjects were 400 myopia patients aged 8-16 years who were admitted to the orthokeratology fitting center of our hospital from June 2019 to May 2022, with 400 eyes(including right eye data analysis). The subjects were divided into CRT-S group(BOZD<6.0 mm), CRT group(BOZD=6.0 mm), VST-S group(BOZD<6.2 mm), VST group(BOZD=6.2 mm)according to the brand of orthokeratology lens and BOZD group, with 100 cases in each group. Uncorrected visual acuity(UCVA), corneal flat K value, axial length, spherical equivalent, and incidence of corneal injury were collected and analyzed at 1 d, 1 wk, 1 and 6 mo, 1 and 2 a, respectively.RESULTS:After wearing lenses for 1 d, the UCVA of the VST-S group improved the fastest, but after 1 wk, all groups reached a good UCVA, and there was no significant difference between groups. The corneal flat K value of the CRT-S group decreased the most after wearing lenses for 6 mo, and there was no significant difference in the corneal flat K value of all groups after 1 year of lens wearing. At each time point, the axial length growth decreased significantly after reducing the BOZD of the same brand of orthokeratology lens. At 6 mo, there was no significant difference in the axial length growth and defocus ring diameter between the CRT-S group and the VST-S group, but at 1 and 2 a, the VST-S group had significantly lower axial length growth and defocus ring diameter than the CRT-S group. The growth of the diopter sphere and spherical equivalent(SE)was significantly reduced when the BOZD of the same brand of orthokeratology lens was reduced at 2 a follow-up. The VST-S group had the smallest changes in the degree of SE and had the best myopia control effect. There was no significant difference in the change value of the diopter cylinder and the incidence of corneal injury among the four groups.CONCLUSION:Reducing the BOZD of the orthokeratology lens can effectively control the growth of the axial length and the progression of myopia degree. The myopia control effect of the VST lens is better than that of the CRT lens after reducing the BOZD. Reducing the BOZD of the orthokeratology lens does not increase the risk of additional corneal injury.
