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.

Viruses constitute a significant group of pathogens that have caused numerous fatalities and substantial economic losses in recent years, particularly with the emergence of coronaviruses. While the impact of SARS-CoV-2 appears to be diminishing in daily life, only a limited number of drugs have received approval or emergency use authorization for its treatment. Given the high mutation rate of viral genomes, host-directed agents (HDAs) have emerged as a preferred choice due to their broad applicability and lasting effectiveness. In contrast to direct-acting antivirals (DAAs), HDAs offer several advantages, including broad-spectrum antiviral activities, potential efficacy against future emerging viruses, and a lower likelihood of inducing drug resistance. In our review article, we have synthesized known host-directed antiviral targets that span diverse cellular pathways and mechanisms, shedding light on the intricate interplay between host cells and viruses. Additionally, we have provided a brief overview of the development of HDAs based on these targets. We aim for this comprehensive analysis to offer valuable perspectives and insights that can guide future antiviral research and drug development efforts.

This study investigated the role of the nuclear factor of activated T cells c3 (NFATc3) in vascular smooth muscle cells (VSMCs) during aortic aneurysm and dissection (AAD) progression and the underlying molecular mechanisms. Cytoplasmic and nuclear NFATc3 levels were elevated in human and mouse AAD. VSMC-NFATc3 deletion reduced thoracic AAD (TAAD) and abdominal aortic aneurysm (AAA) progression in mice, contrary to VSMC-NFATc3 overexpression. VSMC-NFATc3 deletion reduced extracellular matrix (ECM) degradation and maintained the VSMC contractile phenotype. Nuclear NFATc3 targeted and transcriptionally upregulated matrix metalloproteinase 9 (MMP9) and MMP2, promoting ECM degradation and AAD development. NFATc3 promoted VSMC phenotypic switching by binding to eukaryotic elongation factor 2 (eEF2) and inhibiting its phosphorylation in the VSMC cytoplasm. Restoring eEF2 reversed the beneficial effects in VSMC-specific NFATc3-knockout mice. Cabamiquine-targets eEF2 and inhibits protein synthesis-inhibited AAD development and progression in VSMC-NFATc3-overexpressing mice. VSMC-NFATc3 promoted VSMC switch and ECM degradation while exacerbating AAD development, making it a novel potential therapeutic target for preventing and treating AAD.

This paper summarized the clinical experience of Professor LIU Shenlin in diagnosing and treating gastric cancer with the thinking of "prescription according to tendency". In this paper， the thinking of diagnosis and treatment for gastric cancer and medication skills were summarized into four dimensions： power， energy， chronology and situation. The diagnosis emphasizes the tendency of qi power， considering that the onset of gastric cancer primarily stems from the disorder of qi movement in zang-fu organs， and emphasizing the importance of regulating the liver and spleen qi to intercept the tendency of disease. It points out that dampness-phlegm-stasis-toxin is a crucial link leading to the metabolic imbalance of body energy， and Professor LIU adepts at using methods such as breaking up blood and expelling stasis， and clearing heat and resolving toxins to block the pathological chain reaction caused by energy imbalance and to restore the homeostasis of the organism. In the treatment process， according to the characteristics of gastric cancer staging and chronological evolution， we will explore the changes of the exuberance and weakness of healthy qi and pathogenic qi in the context of the chronologic tendency， and adjust the dosage of attacking and tonic medicines in different stages of the disease in order to balance and restore the body. The "situation" is in line with the state of consumptive disease in advanced gastric cancer， Professor LIU skillfully uses large doses of Huangqi （Astragalus mongholicus） with flexible combination of medicinals to replenish deficiencies， invigorate qi， and regulate blood vessels.

BACKGROUND:Numerous clinical studies have suggested a close relationship between obesity and osteoporosis,but whether there is a genetic causal effect between obesity and osteoporosis remains unclear. OBJECTIVE:To explore the association between obesity and osteoporosis using summary data from a large-scale genome-wide association study(GWAS)through Mendelian randomization analysis. METHODS:Obesity data were derived from summary statistics of the Genetic Investigation of Anthropometric Traits(GIANT)and the UK Biobank(UKBB).Osteoporosis data were obtained from the Genetic Factors for Osteoporosis(GeFOS)consortium,including two bone density phenotypes:total body bone mineral density(BMD)and heel BMD.The inverse variance-weighted method was the primary analysis,with the Mendelian randomization method based on Egger regression(MR-Egger)and weighted median method as supplementary approaches to calculate the causal association between genetic variations related to obesity and osteoporosis.Sensitivity analyses were conducted to validate the reliability of the results.Heterogeneity was assessed using Cochran's Q test.Horizontal pleiotropy was assessed through the MR-Egger intercept test.Leave-one-out analysis was performed to evaluate the potential influence of single nucleotide polymorphisms on the combined inverse variance-weighted estimates. RESULTS AND CONCLUSION:(1)Impact of obesity on osteoporosis:In addition to body mass index and forearm BMD,body mass index,waist-to-hip ratio,body mass index-adjusted waist-to-hip ratio,and whole-body body mass index,heel BMD,forearm BMD,lumbar spine BMD,and femoral neck BMD were causally related to each other.Further Meta-analysis revealed that obesity increased the risk of BMD(odds ratio=1.07,95%confidence interval:1.03-1.12,P<0.01).(2)Impact of osteoporosis on obesity:Apart from arm BMD and lumbar spine BMD as exposure factors showing causal relationships with obesity,other datasets indicated no causal effect between total body BMD,heel BMD,femoral neck BMD,and obesity.Additional meta-analysis demonstrated that BMD did not increase the risk of obesity(odds rate=0.99,95%confidence interval:0.98-1.01,P<0.01).There is a causal relationship between obesity and osteoporosis,suggesting that obesity may be a risk factor for osteoporosis.However,no causal association is found between osteoporosis and obesity.

ObjectiveTo evaluate the validity of four screening questionnaires on chronic obstructive pulmonary disease (COPD) among community residents in Shanghai, and to provide a scientific basis for selecting suitable screening questionnaires and plans for the community use. MethodsA multi-stage random sampling method was used to select community residents aged ≥40 for COPD questionnaire screening and spirometry. The screening questionnaires included the COPD Population Screener Questionnaire (COPD-PS), the COPD Screening Questionnaire (COPD-SQ), the COPD Diagnosis Questionnaire (CDQ), and the Lung Function Questionnaire (LFQ). The diagnostic gold standard for COPD was defined as a ratio of post-bronchodilator forced expiratory volume in one second to forced vital capacity (FEV1/FVC) less than 0.7. The receiver operating characteristic (ROC) curve was used to assess the validity of each questionnaire, and DeLong’s test was used to compare the area under the curve (AUC) of different questionnaires. ResultsAmong the 1 122 residents screened, 99 (8.8%) were diagnosed with COPD based on the gold standard criteria. The AUC values for the four questionnaires ranged from 0.643 to 0.682, with no statistically significant differences in screening accuracy among them (P>0.05). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for each questionnaire at recommended cut-off points were as follows: COPD-PS (sensitivity: 33.3%, specificity: 84.9%, PPV: 17.6%, NPV: 92.9%), COPD-SQ (34.3%, 85.8%, 19.0%, 93.1%), CDQ (73.7%, 42.4%, 11.0%, 94.4%), and LFQ (48.5%, 74.8%, 15.7%, 93.8%). Optimal cut-off values for this population differed from the recommended values. When selecting the optimal cut-off value, the sensitivity of COPD-PS (58.6%), COPD-SQ (55.6%), and LFQ (64.7%) increased, while the specificity of CDQ (75.9%) increased. The AUC of sequential lung function testing for all four screening questionnaires increased to 0.7 or above. The optimal cut-off values for the four questionnaires in this population differed from the recommended values. When applying the optimal cut-off values, the sensitivity of three questionnaires increased: COPD-PS (58.6%), COPD-SQ (55.6%), and LFQ (64.7%), while the specificity of CDQ rose to 75.9%. The AUC of each questionnaire increased to above 0.7 when followed by sequential lung function testing. ConclusionThe COPD-PS, COPD-SQ, CDQ, and LFQ have limited value for COPD screening among Shanghai community residents, indicating that further refinement of these tools is needed.

OBJECTIVE To investigate the effect of Jianpi Yangzheng(JPYZ)formula regulating tumor-associated macrophage(TAM)exosomes on anoikis in gastric cancer and its mechanism.METHODS TAM model was established by inducing human mononuclear THP-1 cells in vitro;M0,TAM and TAM+JPYZ formula exosomes were extracted by ultracentrifugation and co-incuba-ted with gastric cancer cells.Flow cytometry was used to detect the effect of exosomes in each group on anoikis in gastric cancer cells.A BALB/c transplanted tumor mouse model was constructed,and the expression level of apoptotic proteins in transplanted tumors was detected by Western blot.Label-free mass spectrometry proteomics and bioinformatics were used to analyze the differential proteins in gastric cancer cells before and after intervention;Western blot and qPCR experiments were used to detect the expression level of dif-ferential protein isocitrate dehydrogenase 1(IDH1),and ubiquitination experiments were used to detect the ubiquitination level of IDH1;kits were used to detect the levels of α-ketoglutarate(α-KG),NADPH/NADP+,glutathione(GSH/GSSG)and reactive oxy-gen species(ROS)content.RESULTS The anoikis rate of gastric cancer cells was reduced after TAM exosomes intervention(P<0.05,P<0.01),while it was significantly increased after TAM+JPYZ exosomes intervention(P<0.05,P<0.01).In the in vivo mouse experiment,the ratio of Cleaved Caspase-3/Caspase-3 in the tumor of the TAM exosome group was reduced(P<0.05),while the ra-tio was significantly increased after TAM+JPYZ exosome intervention(P<0.05).Proteomic analysis showed that IDH1 was significant-ly different after intervention,and was related to tricarboxylic acid cycle metabolism.Compared with the M0 group,the IDH1 ubiquiti-nation level of gastric cancer cells in the TAM group with exosome intervention was increased,the levels of α-KG,NADPH/NADP+and GSH/GSSG were significantly increased,and the ROS content was reduced(P<0.05),while TAM+JPYZ exosomes could reverse the above phenomenon.CONCLUSION JPYZ Formula can regulate TAM exosomes to cause ubiquitin degradation of IDH1 in gas-tric cancer cells,reduce the level of tricarboxylic acid cycle metabolism in gastric cancer cells,promote ROS accumulation,induce anoikis in gastric cancer,and thus inhibit the development of gastric cancer.

Objective:To evaluate the role of hippocampal prostaglandin-endoperoxide synthase 2 (PTGS2) in baicalin-induced reduction of cognitive dysfunction after cerebral ischemia-reperfusion injury (CIRI) in mice.Methods:Thirty healthy male C57BL/6 mice, aged 16 weeks, weighing 20-25 g, were divided into 5 groups ( n=6 each) using a random number table method: control group (C group), CIRI group, baicalin+ CIRI group (B+ CIRI group), overexpression of PTGS2+ CIRI group (PTGS2+ CIRI group), and overexpression of PTGS2+ baicalin+ CIRI group (PTGS2+ B+ CIRI). In B+ CIRI group and PTGS2+ B+ CIRI group, baicalin-liposome 0.2 ml was injected through the tail vein, and the CIRI model was established 1 week later. In PTGS2+ CIRI group and PTGS2+ B+ CIRI group, PTGS2-overexpressed adeno-associated virus 1.2 μl was injected into the hippocampus, and the CIRI model was established 4 weeks later. CIRI model was established by using the transient (50 min) bilateral common carotid artery occlusion/reperfusion. On the 12th day after developing the model, the spatial learning and memory ability was evaluated using Morris water maze test. The expression of PTGS2 in the hippocampus was detected by Western blot, and the expression of tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), IL-6, Iba-1 and CD68 mRNA in the hippocampus was detected by quantitative real-time polymerase chain reaction. Results:Compared with C group, the escape latency was significantly prolonged, the time spent in the target quadrant was shortened, the number of crossing the original platform was reduced, and the expression of PTGS2 and expression of Iba-1, CD68, TNF-α, IL-1β and IL-6 mRNA in the hippocampus was up-regulated in CIRI group ( P<0.05). Compared with CIRI group, the escape latency was significantly shortened, the time spent in the target quadrant was prolonged, the number of crossing the original platform was increased, and the expression of PTGS2 and expression of Iba-1, CD68, TNF-α, IL-1β and IL-6 mRNA in the hippocampus was down-regulated in B+ CIRI group, and the escape latency was significantly prolonged, the time spent in the target quadrant was shortened, the number of crossing the original platform was reduced, and the expression of PTGS2 and expression of Iba-1, CD68, TNF-α, IL-1β and IL-6 mRNA in the hippocampus was up-regulated in PTGS2+ CIRI group ( P<0.05). Compared with B+ CIRI group, the escape latency was significantly prolonged, the time spent in the target quadrant was shortened, the number of crossing the original platform was reduced, and the expression of PTGS2 and expression of Iba-1, CD68, TNF-α, IL-1β and IL-6 mRNA in the hippocampus was up-regulated in PTGS2+ B+ CIRI group ( P<0.05). Conclusions:The mechanism by which baicalin attenuates cognitive dysfunction after CIRI is related to down-regulation of hippocampal PTGS2 expression and inhibition of neuroinflammation in mice.

Objective:To establish the ultra-high performance liquid chromatography (UPLC) fingerprint and high performance liquid chromatography (HPLC) content determination method of Curcumae Radix standard decoction; To predict the quality markers of Curcumae Radix standard decoction combined with network pharmacology.Methods:UPLC method was used to establish the fingerprint of Curcumae Radix standard decoction, and the common peaks were determined. Combined with chemical pattern recognition techniques such as similarity analysis and clustering analysis, Curcumae Radix standard decoction from different producing areas was studied, and curcumol was used as an index to determine the content of 24 batches of Curcumae Radix standard decoction. At the same time, network pharmacology was used to predict potential of curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one.Results:A total of 24 batches of Curcumae Radix standard decoction from different habitats were compared and analyzed, and 10 common peaks were calibrated. The similarity of 24 batches of samples ranged from 0.982 to 0.999. Clustering analysis and principal component analysis divided them into three categories. Heat map analysis showed that peak 8 (curcumol) and peak 9 ((1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one) were the main components. The content of curcumol in 24 batches of Curcumae Radix standard decoction was 0.69-1.87 mg/g; curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β- (3-oxobutyl) bicyclo [4.1.0] heptan-3-one may regulate the neuroactive ligand-receptor interaction signaling pathway, calcium signaling, and excitation by regulating neuroactive ligand-receptor interaction signaling pathway, calcium signaling, and excitation. It was preliminarily predicted that curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one were potential quality markers of Curcumae Radix.Conclusion:Curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one are potential quality markers of Curcumae Radix standard decoction, and the established fingerprint can be used for the quality control of Curcumae Radix standard decoction.

Objective To investigate the effect of inhibiting the expression of RNA component of mitochondrial RNA processing endoribonuclease(RMRP)on the proliferation and invasion of human lung cancer cell line A549 in order to provide evidence to support the research on NSCLC mechanism.Methods A total of 122 cases of patients who underwent surgical treatment were selected in Jiaozuo People's Hospital from March 2016 to March 2021.In the same period,50 healthy people from physical examination center were selected as the control group.RT-qPCR was used to detect the expressions of RMRP in blood and tissues.Human lung cancer cell line A549 was cultured and divided into si-RMRP group,siRNA-NC group and blank group.RT-qPCR,CCK-8 and Transwell assays were used to detect the expression of RMRP,proliferation activity and cell counting of invasive cells.Results The rel-ative expression level of RMRP in the blood of NSCLC patients was significantly higher than that of control group(P<0.001).The relative expression level of RMRP in NSCLC tissues was significantly higher than the adjacent tissues(P<0.001).The relative expression level of RMRP in blood and tissues of patients with poorly differenti-ated,lymph node metastasis and TNM stage Ⅲ compared with moderate to highly differentiated,no lymph node metastasis and TNM stage Ⅰ-Ⅱ were significantly increased(P<0.05).The relative expression level of RMRP in the cells of the si-RMRP group was lower than that of blank and the siRNA-NC group(P<0.001).Compared with the blank group and the siRNA-NC group,the absorbance(A)value of cells at 24,48,72 and 96 h in the si-RMRP group was decreased(P<0.05).The number of invasion cells in the si-RMRP group was lower than that in the blank group and the siRNA-NC group(F=27.765,P<0.001).Conclusions The relative expression levels of RMRP in blood and tissues of NSCLC patients are increased.Down-regulation of the expres-sion of RMRP gene in A549 cells can inhibit cell proliferation and reduce cell invasion.
