ObjectiveTo observe the effects of Xiaoyaosan on glucagon-like peptide-1 (GLP-1)/GLP-1 receptor (GLP-1r) and protein kinase A (PKA)/cAMP response element binding protein (CREB)/brain-derived neurotrophic factor (BDNF) signaling pathways in the hippocampal CA1 region of rats under chronic restraint stress (CRS),and to explore the mechanism of this formula to alleviate anxiety and depression-like behaviors. Methods40 specific pathogen-free male Sprague-Dawley (SD) rats were randomly divided into normal,model,Xiaoyaosan,and fluoxetine groups,with 10 rats in each group. CRS was used to induce anxiety and depression-like behaviors. The rats in the Xiaoyaosan group were gavaged with aqueous solution of traditional Chinese medicine formula granules (7.36 g·kg-1·d-1),while those in the fluoxetine group were gavaged with aqueous solution of fluoxetine (2 mg·kg-1·d-1). Body weight was measured on days 0,7,14,and 21 of the experiment. On days 0 and 22 of the experiment,the sucrose preference test (SPT),forced swimming test (FST),and open field test (OFT) were performed. The pathological morphology of the hippocampal CA1 region was observed by Nissl staining. The relative mRNA expression of post-synaptic density protein-95 (PSD95) and synapsin (SYP) was detected by reverse transcription quantitative real-time polymerase chain reaction. Immunohistochemistry and Western blot were used to detect expression of proteins in the GLP-1/GLP-1r and PKA/CREB/BDNF pathways in the hippocampal CA1 region. ResultsAfter CRS modeling,compared with the normal group,the rats of the model group had anxiety and depression-like behavioral manifestations,neuronal damage in the hippocampal CA1 region,significantly downregulated expression of synaptic plasticity markers PSD95 and SYP genes (P<0.01),and inhibition of GLP-1/GLP-1r and PKA/CREB/BDNF signaling pathways (P<0.05,P<0.01). Compared with the model group,the Xiaoyaosan group exhibited alleviated anxiety and depression-like behaviors,reduced neuronal damage in the hippocampal CA1 region, significantly increased expression of PSD95 and SYP genes (P<0.01),and the activation of the GLP-1/GLP-1r and PKA/CREB/BDNF signaling pathways (P<0.05,P<0.01). ConclusionXiaoyaosan can alleviate anxiety and depression-like behaviors in CRS rats by improving synaptic plasticity in the hippocampal CA1 region. The mechanisms may be related to the activation of the GLP-1/GLP-1r pathway and its mediated PKA/CREB/BDNF signaling pathway by the formula.

ObjectiveThis study aims to explore the mechanism by which Yishen Huoxue Tongqiao Formula improves metabolism-neuroplasticity and treats unilateral vestibular labyrinth destruction by regulating the metabolic balance of glutamate (Glu)/γ-aminobutyric acid (GABA). Methods48 Sprague-Dawley (SD) adult rats were randomly divided into the sham operation group, model group, Yishen Huoxue Tongqiao Formula groups with low, medium, and high doses (9.20, 18.39, 36.78 g·kg-1), and betahistine group (1.62 mg·kg-1). A unilateral vestibular labyrinth destruction (vestibular dysfunction) model was established by intratympanic injection of chloroform into the right ear, while the control group received intratympanic injection of normal saline. Drugs were administered once daily for seven consecutive days. During the period, behavioral tests were performed to evaluate the behaviors of rats after unilateral vestibular labyrinth destruction. Hematoxylin-eosin (HE) staining and Nissl staining were used to observe the neuronal morphology in the medial vestibular nucleus. Golgi staining was employed to assess the number of dendritic spines of neurons in the medial vestibular nucleus. Ultra-performance liquid chromatography-tandem mass spectrometry (LC-ESI-MS/MS) was utilized to detect Glu/GABA. Immunofluorescence and immunohistochemistry were used to detect the expressions of neuronal nuclei (NeuN), growth-associated protein 43 (GAP-43), and glial fibrillary acidic protein (GFAP). Western blot and real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) were applied to determine the expressions of glutamate-immunoreactive (Glu-IR), GABA, GFAP, postsynaptic density protein 95 (PSD-95), and GAP-43. ResultsCompared with the sham operation group, the model group presented with head deviation, balance disorder, increased tail suspension score, nuclear consolidation of medial vestibular nerve neurons, and decreased Nissl bodies (P<0.01). The number of dendritic spines in neurons and NeuN-positive cells decreased. The content of Glu decreased. The content of GABA increased (Glu/GABA decreased). The expression of GAP-43 was down-regulated, and GFAP was up-regulated (P<0.05, P<0.01). The expressions of Glu-IR, PSD-95, and GAP-43 proteins, as well as Glu-IR mRNA decreased, while the expressions of GABA and GFAP proteins and mRNA increased (P<0.05, P<0.01). Compared with those in the model group, the head deviation, imbalanced behavior, and tail suspension scores in each treatment group decreased, with alleviated neuronal injury and recovered Nissl bodies (P<0.01). The number of dendritic spines of neurons increased, and the number of NeuN-positive cells rebounded. The content of Glu increased, and the content of GABA decreased (Glu/GABA increased). GFAP was down-regulated, and GAP-43 was up-regulated (P<0.05, P<0.01). The expressions of Glu-IR, PMD-95, and GAP-43 proteins, as well as Glu-IR mRNA increased, while the expressions of GABA and GFAP proteins and mRNA decreased. The effect was more significant in the high-dose group (P<0.01). ConclusionThe Yishen Huoxue Tongqiao Formula can alleviate vestibular dysfunction, and its mechanism may be associated with regulating the metabolic balance of Glu/GABA, mitigating neural damage, improving synaptic plasticity (promoting GAP-43 expression and inhibiting GFAP expression), and facilitating vestibular compensation.

OBJECTIVE To explore a model for constructing a platform for medical institution formulation and provide insights for promoting their development. METHODS By systematically reviewing the development status and challenges of medical institution preparations in China, and based on the theory of industry-university-research collaborative innovation, the organizational structure, collaborative processes, and safeguard mechanisms of the platform were designed. RESULTS & CONCLUSIONS Medical institution formulations in China mainly faced challenges such as weak research and development (R&D) capacity, uneven quality standards, and blocked transformation pathways. This study established a full-chain, whole- industry collaborative innovation network covering the government, medical institutions, universities/research institutes, pharmaceutical enterprises, and the market, forming a new “government-industry-university-research-application” five-in-one platform model for medical institution formulations. By establishing mechanisms such as multi-entity collaborative cooperation, full- chain intellectual property management, contribution-based benefit distribution, staged risk-sharing, and third-party evaluation, the model clarified the responsibilities and collaborative pathways of all parties. The new model highlights the whole-process transformation of clinical experience-based prescriptions, enabling precise alignment between clinical needs and technological R&D, as well as between preparation achievements and industrial transformation. While breaking down the barriers of traditional platform construction, it effectively achieves optimal resource allocation and complementary advantages, addresses problems emerging in the development of medical institution preparations, and provides reference value for the formulation of relevant systems.

OBJECTIVE To evaluate the efficacy and safety of total glucosides of paeonia (TGP) in the treatment of systemic lupus erythematosus (SLE). METHODS Randomized controlled trial (RCT) about TGP combined with western medicine versus western medicine alone for SLE treatment were retrieved from PubMed, Embase, Cochrane Library, Web of Science, CNKI, VIP, Wanfang Data, and CBM. The search period spanned from the inception of each database to June 1, 2025. After literature screening, data extraction, and quality assessment of the included studies, Meta-analysis was performed using RevMan 5.4 software. RESULTS Fifteen RCTs, involving 1 318 patients, were included. Meta-analysis results showed that compared with western medicine alone, TGP combined with western medicine significantly improved clinical efficacy [OR=4.96, 95%CI(3.41, 7.23), P<0.000 01], complement 3 [MD=0.18, 95%CI (0.13, 0.23), P<0.000 01] and complement 4[MD=0.08, 般021) 95%CI (0.04, 0.11), P<0.000 01], and reduced the levels of immunoglobulin G (IgG) [MD=-3.10, 95%CI (-3.59,-2.62), P<0.000 01], IgA [MD=-0.68, 95%CI (-0.78, -0.58), P<0.000 01], IgM [MD=-0.43, 95%CI (-0.53,-0.34), P<0.000 01], systemic lupus erythematosus disease activity index (SLEDAI) [MD=-1.59, 95%CI (-2.20, -0.99), P<0.000 01], recurrence rate [OR=0.23, 95%CI (0.13, 0.42), P<0.000 01] and the incidence of adverse drug reactions [OR= 0.54, 95%CI (0.36, 0.82), P=0.004]. CONCLUSIONS TGP therapy can improve clinical efficacy of SLE patients, promote the restoration of immunoglobulins and complements, reduce SLEDAI and recurrence rate and has good safety.

Chinese Journal of School Health 2026;47(1):70-74
Objective:
To understand the impact of childhood trauma on psychological distress among upper grade elemetary school students, and to explore the mediating role of leisure activities in the relationship, so as to provide a basis for developing mental health intervention strategies.
Methods:
From August to November 2024, a combination of convenience sampling and stratified cluster random sampling was employed to recruit 1 373 fourth to sixth grade students from four primary schools in Harbin. The Childhood Trauma Questionnaire(CTQ), a self designed leisure activity scale (including active and passive leisure activities), and the Kessler Psychological Distress Scale (K10) were used to assess childhood trauma experiences, leisure activities, and levels of psychological distress. Spearman correlation analysis and linear regression analysis were conducted to explore the relationships among childhood trauma, leisure types, leisure time, and psychological distress. Based on the mediation analysis framework proposed by Hayes (Model 4), the mediating role of leisure types in the relationship between childhood trauma and psychological distress was examined.
Results:
Totally 19.1% of the upper elemetary school students exhibited psychological distress, while 30.2% had experienced childhood trauma. During school days, 64.6% of the students were reported of having leisure time concentrated between 1 and 5 hours per day, whereas 67.4% reported leisure time exceeding 5 hours per day on weekends. After controlling for potential demographic confounders such as gender, grade, ethnicity, household registration, being an only child, parents educational level, co residence, and whether parents are first time married,linear regression analysis showed that childhood trauma experience had positive predictive effect on psychological distress in upper primary school students( β =0.20, P <0.01). Leisure time showed no statistically significant association with psychological distress, both on school days ( β =-0.58 to -0.56) and weekends ( β =0.26- 0.98 )(all P >0.05). Active leisure activities were negatively associated with psychological distress ( β =-0.20), while passive leisure activities were positively associated with psychological distress ( β =0.29)(both P <0.01). Leisure type partially mediated the relationship between childhood trauma and psychological distress, accounting for 11.7% of the indirect effect.
Conclusion
Childhood trauma experiences positively predict psychological distress in upper elementary school students, and affect psychological distress through active leisure and passive leisure.

Objective:
To analyze adverse event following immunization(AEFI) with the domestic bivalent human papilloma virus (HPV) vaccine among female students in primary, junior, and senior high schools in Hebei Province from 2022 to 2024, aiming to provide evidence for the vaccination program.
Methods:
On May 14, 2025, AEFI case data and vaccination data for the domestic bivalent HPV vaccine among female students in primary, junior, and senior high schools in Hebei Province from 2022 to 2024 were collected from the China Disease Control and Prevention Information System and the Hebei Provincial Immunization Program Information Management System, respectively. Statistical analysis was performed by using descriptive and analytical epidemiological methods, with intergroup comparisons conducted by using the Chi square test or Fisher s exact probability test.
Results:
From 2022 to 2024, a total of 817 900 doses of the domestic bivalent HPV vaccine were administered to female students in primary, junior, and senior high schools in Hebei Province. A total of 68 AEFI cases were reported, comprising 57 common vaccine reactions, 7 rare vaccine reactions, 3 coincidental events, and 1 psychogenic reaction. The overall AEFI reporting rate was 8.31 per 100 000 doses, 4 cases (2.30/100 000 doses), 31 cases (8.73/100 000 doses), and 33 cases (11.41/100 000 doses) were reported in 2022, 2023, and 2024, respectively, with a statistically significant difference across years ( χ 2=10.97, P <0.01). The reporting rates for common and rare vaccine reactions were 6.97 per 100 000 doses and 0.86 per 100 000 doses, respectively. The AEFI reporting rates were 15.14 per 100 000 doses among primary school girls and 8.20 per 100 000 doses among secondary school girls, though the difference was not statistically significant (Fisher s exact test, P =0.30). The reporting rate was higher after the first dose (10.91/100 000 doses) than after the second dose (5.96/100 000 doses; χ 2=5.85, P =0.02).The second quarter recorded the highest AEFI reporting rate at 11.21 per 100 000 doses. The majority of AEFI cases (56 cases, 82.35%) occurred within 24 hours post vaccination.
Conclusion
The domestic bivalent HPV vaccine demonstrates a favorable safety profile among female students in Hebei Province, with a low overall AEFI reporting rate that consisted predominantly of general reactions and occasional cardiac related reactions.

[Objective] To investigate and summarize the clinicopathological features, diagnosis, treatment and prognosis of adrenocortical carcinoma with rhabdoid features. [Methods] The clinical diagnosis and treatment of a case of adrenocortical carcinoma with rhabdoid features admitled to Department of Urology, Weifang People's Hospital were reported.The clinical manifestations, pathological features, diagnosis and prognosis of the disease were analyzed in combination with relevant literature. [Results] A 34-year-old male patient was admitted due to scrotal distension and pain that had persisted for 6 months.Imaging examination showed a huge soft tissue tumor in the left adrenal region of the retroperitoneum with compression displacement of the left kidney, leading to obstruction of venous return in the left spermatic vein, which in turn caused varicose veins.The levels of serum renin, angiotensin, aldosterone, cortisol, and catecholamine were within normal ranges.Surgical resection of the tumor was performed, and postoperative pathological examination revealed that the tumor tissue was predominantly composed of rhabdoid cells, exhibiting positive immunohistochemical staining for INI 1, Syn, Calretinin and Vimentin.Genetic testing did not identify any deletion of SMARCB1 and SMARCA4 mutations.Therefore, the diagnosis was adrenocortical carcinoma with rhabdoid features.At the current 20-month follow-up, no recurrence or metastasis was observed.A review of the literature found that only 7 cases of this disease had been reported. [Conclusion] Adrenocortical carcinoma with rhabdoid features is a rare disease, and a definitive diagnosis is dependent upon pathological examination.Surgical resection remains the primary treatment.Long-term follow-up is essential, and further research is needed to evaluate the impact of adjuvant therapy.

[Objective] To extract hemoglobin (Hb) from red blood cells using osmotic pressure swelling method, expected to achieve a hemoglobin dissolution rate of ≥80% and a cell membrane integrity rate of ≥70%. [Methods] Human umbilical cord blood red blood cells were used as raw materials and phosphate buffer solution was used as the swelling solution for red blood cells. A three factor three-level orthogonal experiment (n=3) was conducted to determine the optimal matching conditions for selecting the osmolality molar concentration of phosphate buffer solution, pH value of hypotonic phosphate buffer solution and volume ratio of hypotonic phosphate buffer solution to washed red blood cells. Red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions. The hemoglobin dissolution rate and cell membrane integrity rate were checked. In the expanded comparative experiment, red blood cell swelling solution samples (n=6) were prepared by the optimal matching conditions and the original process conditions, which was filtered by ultrafiltration membranes. The filtration time and hemoglobin yield were checked. [Results] The optimal matching conditions for preparing red blood cell swelling solution were obtained through orthogonal experiment as follows: osmotic pressure molar concentration was 30 mOsmol/Kg, pH was 7.8, and phosphate buffer to red blood cell volume ratio was 6∶1. On the basis of the above conditions, the red blood cell swelling solution sample was compared with the original process sample: the hemoglobin dissolution rate was (82.4±1.8)% vs (78.6±3.0)% (P<0.05), and the cell membrane integrity rate was (65.8±4.0)% vs (28.7±2.3)% (P<0.05). In the expanded comparative experiment, the optimal matching conditions were compared with the original process conditions: filtration time(s) (327±9) vs (434±13) (P<0.05), and hemoglobin yield was (72.3±1.2)% vs (66.0±1.4)% (P<0.05). [Conclusion] Compared with the original preparation process, the hemoglobin extraction process which optimized through orthogonal experiments greatly reduces the cell membrane fragmentation rate and minimizes the entry of cell membrane matrix into the target solution, ensuring a slightly higher hemoglobin dissolution rate, and reducing the preparation difficulty for the subsequent cell membrane separation and further purification.

This paper comprehensively discusses on the potential neurobiological mechanisms of acupuncture in the treatment of tobacco dependence, focusing on three important aspects, including acupuncture's regulation of tobacco dependence behavior, effects of acupuncture on withdrawal syndrome, and the role of acupuncture in preventing relapse. It is found that acupuncture can inhibit drug-seeking behavior by regulating the reward pathway and related neurons, such as dopamine, thus modulating tobacco dependence behavior. It also alleviates withdrawal symptoms by improving the oral environment of smokers and reducing negative emotions after quitting. Furthermore, acupuncture can prevent relapse by decreasing brain network activity related to smoking cravings and improving cognitive brain functions like addiction memory. Currently, research on the specific neurobiological mechanism of acupuncture in treating tobacco dependence and the involved neural circuits is limited. Future research directions are proposed, including the evaluation of clinical effects, exploration of specific therapeutic mechanisms, investigation of brain pathology, and strengthening the exploration of brain functions. Additionally, combining modern technologies to clarify the neural circuits involved in acupuncture intervention will provide a basis for acupuncture treatment of tobacco addiction.

ObjectiveTo investigate the effects of Dihuang Yinzi on the cognitive function in the mouse model of learning and memory impairments induced by scopolamine (SCOP) and explore the treatment mechanism. MethodsA mouse model of learning and memory impairment was induced by intraperitoneal injection of SCOP. Sixty male C57BL/6J mice were randomized into six groups: control (0.9% NaCl, n=10), model (SCOP 1 mg·kg-1·d-1, n=10), low-, medium-, and high-dose Dihuang Yinzi (SCOP 1 mg·kg-1·d-1 + Dihuang Yinzi 5.5, 11.0, and 22.0 g·kg-1·d-1, n=10), and donepezil (SCOP 1 mg·kg-1·d-1 + donepezil 0.84 mg·kg-1·d-1, n=10). Mice were administrated with corresponding drugs for 6 weeks. Modeling started in the 4th week, and mice in other groups except the control group were injected with SCOP intraperitoneally 40 min after daily gavage. Behavioral testing began in the 5th week, 30 min after modeling each day. The Morris water maze and novel object recognition tests were carried out to evaluate the spatial learning and memory function of mice. Nissl staining was employed to observe the survival of neurons and Nissl bodies in the hippocampal CA1 region. Western blot was employed to determine the protein levels of silent information regulator 2 (SIRT2), α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor 1 (GluA1), protein kinase A (PKA), cAMP response element-binding protein (CREB), phosphorylated-CREB (p-CREB), postsynaptic density protein 95 (PSD95), growth-associated protein-43 (GAP-43), and synaptophysin (SYN) in the hippocampus. Immunofluorescence was used to detect the expression of doublecortin (DCX) in the hippocampal dentate gyrus (DG) region. ResultsCompared with the control group, the model group showed impaired learning and memory (P<0.01), obvious neuronal damage in the hippocampal CA1 region, a reduction in neuron survival (P<0.01), a decrease in DCX expression in the hippocampal DG region (P<0.01), down-regulated proteins levels of GluA1, PKA, p-CREB/CREB, PSD95, SYN, and GAP-43 in the hippocampal tissue (P<0.05, P<0.01), and an up-regulated protein level of SIRT2 (P<0.01). Compared with the model group, the medium- and high-dose Dihuang Yinzi groups and the donepezil group showed improvements in learning and memory (P<0.05, P<0.01), while the low-, medium-, and high-dose Dihuang Yinzi groups and the donepezil group had increased neuron survival (P<0.05, P<0.01). The medium-dose Dihuang Yinzi group and the donepezil group showed increased DCX expression (P<0.05, P<0.01). The medium- and high-dose Dihuang Yinzi groups and the donepezil group showed up-regulation in the protein levels of GluA1, PKA, p-CREB/CREB, PSD95, SYN, and GAP-43 (P<0.05, P<0.01) and down-regulation in the protein level of SIRT2 (P<0.01). ConclusionDihuang Yinzi can improve the cognitive function in the mouse model of learning and memory impairments induced by SCOP by inhibiting the upregulation of SIRT2, activating the PKA/CREB signaling pathway, improving synaptic plasticity, and reducing hippocampal neuronal damage.
