Objective: To explore the relationship between related factors of non-suicidal self-injury behavior (NSSI) among middle school students in Guizhou Province, so as to provide the evidence for preventing high risk behaviors in adolescents. Methods: A stratified cluster random sampling method was used to select 1 034 junior and senior middle school students from Zunyi City, Qiannan Prefecture and Tongren City in Guizhou Province from April to October in 2023. Questionnaire survey was conducted to collect information including Adolescent Self injury Scale and Family Assessment Device. The R 4.4.1 software was employed for network analysis visualization, centrality indicators, and result stability assessment. Results: The detection rate of NSSI behavior among middle school students in Guizhou province was 29.6%, with a detection rate of 25.5% for boys and 33.1% for girls, showing a statistically significant difference ( χ 2=7.07, P <0.05). There were statistically significant differences in scores of emotional communication, egoism, family rules, positive communication, problem solving, expression of positive emotions and management of negative emotions self-efficacy, and bullying victimization in various dimensions between middle school students with and without NSSI ( Z =-13.66 to -7.05, P <0.01). NSSI among middle school students was positively correlated with social/relational bullying, depression and anxiety, and there were relatively close connections in the network ( r =0.35, 0.43, 0.42, P <0.01). Centrality indicators showed that the highest in strength and closeness centrality were stress ( Z =1.29, 1.58), the highest in betweenness centrality was for emotional communication ( Z =1.91), and the highest in expected influence index was for physical bullying ( Z =1.44)( P < 0.05). Conclusions Stress, emotional communication and physical bullying have significant impacts in the network of factors related to NSSI. Social/relational bullying, depression and anxiety have strong direct correlations with NSSI behavior among middle school students.

Objective To explore the regulatory effect and mechanism of Zhongfeng Xinglou Tongfu Capsule on the brain inflammatory response of mice with cerebral hemorrhage through cholecystokinin octapeptide(CCK-8)mediated the interleukin 10(IL-10)/signal transduction and transcriptional activator 3(STAT3)signaling pathway.Methods A total of 110 C57BL/6 mice were divided into sham operation group,cerebral hemorrhage group,Zhongfeng Xinglou Tongfu Capsule low-,medium-,and high-dose groups according to the random number table method,with 22 mice in each group.The intracerebral hemorrhage model was established by collagenase method.At 2 hours after the establishment of the model,Zhongfeng Xinglou Tongfu Capsule suspension was intragastrically administered at a dose of 10 mL·kg-1.The sham operation group and the cerebral hemorrhage group were intragastrically administered with the same dose of normal saline.The neurofunctional score and left-turn rate of the mice were recorded.The dry and wet weight method was used to detect brain water content on the 72 h after surgery,and the Western Blot method was used to detect tumor necrosis factor-α(TNF-α),interleukin 1β(IL-1β),interleukin 6(IL-6),interleukin 10(IL-10),and the relative expression levels of JAK-1,STAT3,and p-STAT3 pathway proteins around the hematoma of mice at 72 h after surgery.On the 3rd and 5th day after surgery,Elisa method was used to detect the relative expression level of CCK-8,qPCR method was used to detect the expression levels of IL-10 and STAT3 mRNA.Results Compared with the cerebral hemorrhage group,the NDS scores of mice in the low-,medium-,and high-dose groups of Zhongfeng Xinglou Tongfu Capsules were significantly reduced on the 3rd and 5th days after intervention treatment(P＜0.01).And the left-turn rate in the low-dose group on the 3rd and 5th days after intervention treatment was reduced(P＜0.05),the left-turn rate in the medium-dose group was reduced on the 3rd day(P＜0.05)and the 5th day(P＜0.01).Furthermore,the left-turn rate was obviously reduced on the 3rd and 5th day in the high-dose group(P＜0.01).The brain water content of mice in the low-dose group was reduced(P＜0.05),and the brain water content of mice in the medium-and high-dose groups was significantly reduced(P＜0.01).In the low-dose group,the expressions of pro-inflammatory factors TNF-α,IL-6 and JAK-1,STAT3,and p-STAT3 pathway proteins were significantly reduced(P＜0.01),while the expression of IL-1β was reduced(P＜0.05),the expression of IL-10 increased significantly(P＜0.01).The expression of pro-inflammatory factors TNF-α,IL-1β,IL-6,as well as JAK-1,STAT3,and p-STAT3 pathway proteins in the medium-and high-dose groups was significantly reduced(P＜0.01),the expression of anti-inflammatory factor IL-10 increased significantly(P＜0.01).The content of CCK-8 in the low-dose group was increased on the 3rd day after treatment(P＜0.05),and the content increased significantly on the 5th day(P＜0.01).The content of CCK-8 in the medium-and high-dose groups obviously increased on the 3rd and the 5th day after treatment(P＜0.01).The relative expression level of IL-10 mRNA was significantly increased after treatment(P＜0.01),but the relative expression level of STAT3 mRNA was significantly decreased after treatment(P＜0.01).Conclusion Zhongfeng Xinglou Tongfu Capsule can target the content of brain-gut peptide CCK-8 and regulate the IL-10/STAT3 signaling pathway to reduce the secondary inflammatory reaction and cytotoxic brain edema after cerebral hemorrhage.

ObjectiveTo analyze the expression of molecular marker affecting the prognosis of acute myeloid leukemia （AML） patients from bioinformatics database， thus providing an experimental basis for further exploration of a novel molecular marker for the prognosis of AML. MethodsThe prognostic data of 179 AML patients from The Cancer Genome Atlas （TCGA） database were examined for differential gene analysis and survival analysis. The bone marrow samples of 74 healthy individuals （HI） and 542 de novo AML patients in the dataset GSE13159 downloaded from the Gene Expression Omnibus （GEO） database were analyzed to detect the difference in the expression levels of differential target genes. Peripheral blood and bone marrow samples were collected from 18 de novo AML patients and 20 age- and gender-matched healthy controls， and real-time fluorescent quantitative PCR was used to validate the expression levels of the differential genes in the AML patients. ResultsBioinformatics data analysis showed that the optimal cut-off value of Homo sapiens NK2 homeobox 3 （NKX2-3） calculated by R language was 0.051. Survival analysis revealed a statistically poorer overall survival in de novo AML patients with high NKX2-3 expression than in those with low NKX2-3 expression （P = 0.0036）. NKX2-3 was highly expressed in patients with de novo AML than in HI and the difference was statistically significant （P < 0.001）. Real-time fluorescence quantitative PCR verified the expression levels of the NKX2-3 gene in AML patients and confirmed that compared with those in HI， in the de novo AML patients， NKX2-3-1 and NKX2-3-2 were highly expressed and were significantly correlated （P = 0.000， P = 0.000）. ConclusionNKX2-3 is highly expressed in de novo AML patients， and the AML patients with high NKX2-3 expression have poor overal survival. NKX2-3 may be closely related to the clinical outcome and prognosis of AML.

To investigate the mechanism of Wenshen Xuanbi Decoction (WSXB) in treating osteoarthritis (OA) via network pharmacology, bioinformatics analysis, and experimental verification. The active components and prediction targets of WSXB were obtained from the TCMSP database and Swiss Target Prediction website, respectively. OA-related genes were retrieved from GeneCards and OMIM databases.Protein-protein interaction and functional enrichment analyses were performed, resulting in the construction of the Herb-Component-Target network. In addition, differential genes of OA were obtained from the GEO database to verify the potential mechanism of WSXB in OA treatment. Subsequently, potential active components were subjected to molecular verification with the hub targets. Finally, we selected the most crucial hub targets and pathways for experimental verification in vitro. The active components in the study included quercetin, linolenic acid, methyl linoleate, isobergapten, and beta-sitosterol. AKT1, tumor necrosis factor (TNF), interleukin (IL)-6, GAPDH, and CTNNB1 were identified as the most crucial hub targets. Molecular docking revealed that the active components and hub targets exhibited strong binding energy. Experimental verification demonstrated that the mRNA and protein expression levels of IL-6, IL-17, and TNF in the WSXB group were lower than those in the KOA group (p < 0.05). WSXB exhibits a chondroprotective effect on OA and delays disease progression. The mechanism is potentially related to the suppression of IL-17 and TNF signaling pathways and the down-regulation of IL-6.

An effective therapeutic regimen for hepatic fibrosis requires a deep understanding of the pathogenesis mechanism. Hepatic fibrosis is characterized by activated hepatic stellate cells (aHSCs) with an excessive production of extracellular matrix. Although promoted activation of HSCs by M2 macrophages has been demonstrated, the molecular mechanism involved remains ambiguous. Herein, we propose that the vitamin D receptor (VDR) involved in macrophage polarization may regulate the communication between macrophages and HSCs by changing the functions of exosomes. We confirm that activating the VDR can inhibit the effect of M2 macrophages on HSC activation. The exosomes derived from M2 macrophages can promote HSC activation, while stimulating VDR alters the protein profiles and reverses their roles in M2 macrophage exosomes. Smooth muscle cell-associated protein 5 (SMAP-5) was found to be the key effector protein in promoting HSC activation by regulating autophagy flux. Building on these results, we show that a combined treatment of a VDR agonist and a macrophage-targeted exosomal secretion inhibitor achieves an excellent anti-hepatic fibrosis effect. In this study, we aim to elucidate the association between VDR and macrophages in HSC activation. The results contribute to our understanding of the pathogenesis mechanism of hepatic fibrosis, and provide potential therapeutic targets for its treatment.
