ObjectiveTo investigate the mechanisms by which Huanglian Jiedutang (HLJDT) modulates microglial (MG) phenotypes through the sialic acid-binding Ig-like lectin 2 (SIGLEC2/CD22)/Src-homology-2-domain-containing protein tyrosine phosphatase-1 (SHP-1)/phosphorylated protein kinase B (p-Akt) signaling pathway, thereby promoting myelin repair and alleviating agitation-like behaviors in vascular dementia (VAD). MethodsSixty C57BL/6J mice were randomly assigned to a sham (normal) group, model group, HLJDT low-, medium-, and high-dose groups (2.5, 5, and 10 g·kg-1·d-1), and a risperidone group (2 mg·kg-1·d-1), with 10 mice per group. VAD was induced by bilateral common carotid artery stenosis (BCAS). From day 42, mice received drug interventions for 2 weeks. Agitation-like behaviors were assessed using the resident-intruder test. After behavioral testing, ventrolateral part of the ventromedial hypothalamus (VMHvl) tissues were collected. Western blot was used to measure protein levels of myelin oligodendrocyte glycoprotein (MOG), myelin basic protein (MBP), proteolipid protein (PLP), inducible nitric oxide synthase (iNOS), arginase-1 (Arg1), CD86, CD206, and CD22, SHP-1, and p-Akt. Immunofluorescence was used to evaluate myelin-associated glycoprotein (MAG) intensity and the proportion of iNOS+/ionized calcium-binding adapter molecule 1 (Iba1)+ cells. ELISA was used to detect tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-1β. ResultsCompared with the normal group, the model group exhibited markedly increased biting and aggressive behaviors and shortened attack latency (P<0.01). MOG, MBP, and PLP protein levels and MAG fluorescence intensity were significantly reduced (P<0.05, P<0.01). INOS and CD86 expression and TNF-α, IL-6, and IL-1β levels were significantly elevated (P<0.01). CD22 and SHP-1 expression increased significantly (P<0.01), whereas p-Akt expression decreased (P<0.01). Compared with the model group, the medium- and high-dose HLJDT groups and the risperidone group showed markedly reduced biting and aggression (P<0.05, P<0.01) and prolonged attack latency (P<0.01). MOG, MBP, and PLP levels and MAG fluorescence intensity were significantly increased (P<0.05, P<0.01). INOS, CD86, TNF-α, IL-6, and IL-1β levels decreased significantly (P<0.05, P<0.01). CD22 and SHP-1 expression decreased, while p-Akt expression increased significantly (P<0.05, P<0.01). ConclusionHLJDT may modulate CD22/SHP-1/p-Akt signaling in the VMHvl, promote the shift of MG toward an anti-inflammatory and phagocytic phenotype, enhance myelin repair, and improve agitation-like behaviors in VAD mice.

Objective:
To explore impacts of sports games designed based on the information-motivation-behavioral skills model (IMB) on prosocial behavior in children with intellectual and developmental disabilities (IDD) attending regular classes, so as to provide a theoretical basis for promoting the development of prosocial behavior in school age IDD children.
Methods:
From February to March 2023, 40 children with intellectual disabilities aged 8-9 who were enrolled in ordinary schools in Beijing were recruited by using WeChat parents to send messages. They were randomly divided into an experimental group (19 before intervention, 17 after intervention) and a control group (19 before intervention, 19 after intervention) by lottery method. During the study period, children in both groups received the same frequency and quality of regular physical activities. The experimental group, in addition, underwent a 13 week sports game intervention based on the IMB model, 4 times a week, each session lasting 50 minutes. The sports game intervention scheme based on IMB model was divided into two modules,including basic training and development training:low difficulty sports game intervention based on emotion recognition, and medium low difficulty and medium difficulty sports game intervention based on social training such as "prosocial". The Griffith Empathy Measure (GEM) and the Prosocial Behavior Scale for Adolescents (PBSA) were used to assess empathy ability and prosocial behavior levels of children in both groups before and after the intervention.
Results:
After intervention, the cognitive empathy dimension, emotional empathy dimension and total score of GEM in the experimental group (39.15±2.85, 38.54±1.94, 77.69±3.95) were higher than control group (32.18±4.18, 32.28± 4.28, 64.56±6.48) and before intervention (33.92±4.94, 31.30±4.61, 65.23±8.47), and the differences were statistically significant ( F =12.06, 6.99, 14.90; 8.95, 7.36, 13.22, P <0.05). After intervention, compliance with public welfare factors, trait factors and total score (31.33±1.97, 16.67±1.03, 71.83±2.93) were higher than control group (22.65±1.58, 12.59±0.71, 59.47± 2.18 ) and before intervention (22.00±1.27, 12.17±0.75, 58.00±1.67), and the differences were statistically significant ( F = 17.00 , 36.54, 12.71; 29.87, 13.09, 13.12, P <0.05).
Conclusion
Sports game intervention based on IMB model can effectively promote the development of prosocial behavior of children with IDD attending regular classes.

OBJECTIVE To compare the efficacy and safety of different daily doses of aspirin in the prevention of preeclampsia (PE). METHODS The case-control studies and prospective randomized controlled trials on aspirin with daily dose ≥ 100 mg (trial group) vs. <100 mg (control group) in the prevention of PE were retrieved from PubMed, Medline, Embase, the Cochrane Library, CNKI, China Biomedical Literatue Database and Wanfang Data from base-building to January 2025. After literature screening, data extraction and quality evaluation, meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 11 literatures were included, involving 3 052 pregnant women. Meta-analysis showed the incidence of PE [RR=0.63, 95%CI (0.53,0.76), P<0.000 01], gestational hypertension [RR=0.69, 95%CI (0.50,0.94),P=0.02], preterm birth [RR=0.56, 95%CI (0.47,0.66), P<0.000 01], and intrauterine growth retardation [RR=0.73,95%CI (0.61,0.87),P=0.000 5] in trial groups were significantly lower than control group. The incidence of postpartum hemorrhage between the two groups had no statistically significant difference [RR=1.17, 95%CI (0.90,1.53),P=0.25]. Subgroup analysis showed that the incidence of PE in Chinese pregnant women taking 150 mg of aspirin was significantly higher than taking 100 mg of aspirin [RR=3.40, 95%CI (1.29, 8.93), P=0.01]; but there was no significant difference between the two groups in the incidences of postpartum hemorrhage, preterm birth (P>0.05). CONCLUSIONS Aspirin with daily dose ≥100 mg is more effective in preventing PE than daily dose <100 mg, with lower rates of gestational hypertension, preterm birth, and intrauterine growth retardation. It does not increase the risk of postpartum hemorrhage. For pregnant women in China, daily dose 100 mg of aspirin may be more effective in preventing PE than 150 mg.

ObjectiveTo investigate the ameliorative effects of quercetin on neuropsychiatric symptoms associated with vascular dementia (VaD) and to elucidate the molecular mechanism, specifically whether quercetin inhibits pro-inflammatory activation of microglia by modulation of the receptor-interacting serine/threonine-protein kinase 1 (RIPK1)/NOD-like receptor protein 3 (NLRP3)/Caspase-1 signaling pathway, thereby promoting myelin repair in the medial prefrontal cortex (mPFC). MethodsA C57BL/6J mouse model of VaD with neuropsychiatric symptoms was established by bilateral common carotid artery stenosis (BCAS) combined with chronic restraint stress (CRS). Mice were randomly divided into a sham group, a model group, low-dose, medium-dose, and high-dose quercetin groups (30, 60, 120 mg·kg-1·d-1), and a fluoxetine group (10 mg·kg-1·d-1). After intervention, depressive- and anxiety-like behaviors were assessed by the sucrose preference test (SPT), forced swim test (FST), open field test (OFT), and elevated plus maze (EPM). mPFC tissue was collected. Immunofluorescence (IF) was used to detect myelin basic protein (MBP) expression and microglial morphology. Western blot was used to measure the protein level of MBP, myelin oligodendrocyte glycoprotein (MOG), myelin-associated glycoprotein (MAG), inducible nitric oxide synthase (iNOS), CD86, RIPK1, phosphorylated RIPK1 (Ser166), NLRP3, and Caspase-1. Enzyme-linked immunosorbent assay (ELISA) was used to determine the level of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β). ResultsCompared with the sham group, the model group exhibited significant depressive- and anxiety-like behaviors (P<0.01), significantly decreased protein expression of MBP, MOG, and MAG in the mPFC (P<0.01), activated microglia (characterized by enlarged cell bodies, reduced protrusions, and upregulated iNOS and CD86 expressions, P<0.01), and significantly elevated p-RIPK1/RIPK1 ratio, NLRP3, Caspase-1 protein expression, and level of TNF-α, IL-6, and IL-1β (P<0.01, P<0.05). Compared with the model group, the quercetin treatment (especially at medium and high doses) significantly ameliorated these behavioral abnormalities (P<0.05, P<0.01), increased the expression of MBP (protein and fluorescence intensity), MOG, and MAG in the mPFC (P<0.05, P<0.01), suppressed excessive microglial activation (characterized decreased cell bodies, increased protrusions, and downregulated iNOS and CD86 expressions, P<0.01), and significantly reduced the p-RIPK1/RIPK1 ratio, NLRP3, Caspase-1 protein expression, and inflammatory cytokine levels (P<0.01). ConclusionQuercetin effectively alleviates neuropsychiatric symptoms in VaD mice. Its mechanism may be associated with the inhibition of microglial inflammatory activation mediated by the RIPK1/NLRP3/Caspase-1 signaling pathway, thereby promoting myelin repair in the mPFC region.

Zuoguiyin, which first recorded in Jingyue Quanshu written by ZHANG Jiebin in the Ming dynasty, was included in the Catalogue of Ancient Famous Classical Formulas(The Second Batch). This study followed the Principles of Textual Research on Key Information of Ancient Famous Classical Formulas to determine the key information of Zuoguiyin in ancient and modern literature, such as the formula origin, the composition of the formula and the origin of the drugs. It was found that the composition, dosage, preparation and processing methods of Zuoguiyin were basically the same as the original formula. The original dosage of this formula is 41.03 g of Rehmanniae Radix Praeparata(the fresh or dried tuberous roots of Rehmannia glutinosa, processed by wine stewing or wine steaming), 7.46 g of Dioscoreae Rhizoma(the dried rhizomes of Dioscorea opposita), 7.46 g of Lycii Fructus(the dried mature fruit of Lycium barbarum), 3.73 g of Glycyrrhizae Radix et Rhizoma Praeparata cum Melle(the dried roots and rhizomes of Glycyrrhiza uralensis, processed by honey-roasted method), 5.595 g of Poria(the sclerotium of Poria cocos), 5.595 g of Corni Fructus(the dried mature fruit pulp of Cornus officinalis). The method of administration is to add 600 mL of water to all the herbs, decoct to 140 mL and take before meals. The function of Zuoguiyin is to nourish Yin and tonify the kidney, and it is often used in the treatment of lumbar soreness and ejaculation, night sweating, dry mouth and throat, thirst and desire to drink, glossy red tongue, thin and rapid pulse, etc. Since ancient times, Zuoguiyin has been used to treat a variety of internal and gynaecological diseases as well as diseases of the nervous, circulatory and reproductive systems that are predominantly caused by kidney Yin deficiency. However, there is not much research on the modern application and therapeutic mechanism of this formula, and there is no standardized preparation in the market, so the degree of development and utilization is not high, and there is still a lot of room for research.

Objective:To evaluate inflammation early in the infarct zone and its dynamic changes after acute myocardial infarction (AMI) using 18F-FDG PET imaging, and analyze its relationship with left ventricular remodeling progression (LVRP). Methods:Sixteen Bama miniature pigs (4-6 months old, 8 females) were selected. AMI models were established by balloon occlusion of the left anterior descending artery. 18F-FDG PET imaging was performed before AMI and at days 1, 5, 8, and 14 post-AMI to evaluate the regional inflammation response. 18F-FDG SUV ratio (SUVR) and the percentage of uptake area of left ventricle (F-extent) in the infarct zone, and the SUVRs of the spleen and bone marrow, were measured. Echocardiography and 99Tc m-methoxyisobutylisonitrile(MIBI) SPECT myocardial perfusion imaging (MPI) were performed at the above time points and on day 28 post-AMI to assess left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), and myocardial perfusion defect extent. The degree of LVRP at day 28 post-AMI was defined as ΔLVESV(%)=(LVESV AMI 28 d-LVESV AMI 1 d)/LVESV AMI 1 d×100%. Data were analyzed using repeated measures analysis of variance, Kruskal-Wallis rank sum test and Pearson correlation analysis. Results:Twelve pigs were successfully modeled and completed the study. Inflammation in the infarct zone persisted until day 14 post-AMI. The SUVR of the infarct zone pre-AMI and at days 1, 5, 8, and 14 post-AMI were 1.03±0.08, 3.49±1.06, 2.93±0.90, 2.38±0.76, and 1.63±0.62, respectively ( F=49.31, P<0.001). The F-extent values in the infarct zone pre-AMI and at days 1, 5, 8, and 14 post-AMI were 0, (40.08±12.46)%, (40.00±12.76)%, (31.08±12.82)%, and 16.50%(7.25%, 22.00%), respectively ( H=37.61, P=0.001). There were no significant differences in the SUVRs of bone marrow and spleen before and after AMI ( F values: 0.69 and 0.77, both P>0.05). At day 1 post-AMI, both SUVR and F-extent in the infarct zone were significantly correlated with LVRP ( r values: 0.82 and 0.70, P values: 0.001 and 0.035). Conclusions:18F-FDG PET imaging can be used to evaluate inflammation in the infarct area and its dynamic changes after AMI. Inflammation in the infarct area is severe at day 1, and then gradually decreases. The extent and severity of inflammation visible on 18F-FDG PET imaging 1 d after AMI are closely related to LVRP.
