This study explores the diagnosis and treatment of needle knife therapy for ankylosing spondylitis (AS) at middle and advanced stage based on the theory of meridian tendons, from a holistic perspective and syndrome differentiation. The treatment strategy includes "harmonizing yin and yang" to address root causes and "tendons-based release" to harmonize qi and blood, with the "tendons nodule points" as the core acupoint selection criterion. Based on this approach, the study systematically elaborates on two needle knife methods for AS: "governor vessel bone-piercing technique" and "below-the-umbilicus release technique", covering indications, acupoint location, and procedures. Clinical case examples are provided to enrich needle knife therapy guided by the theory of meridian tendons, offering insights for clinical and research work on AS.

Alzheimer's disease (AD) is a common neurodegenerative disorder among the elderly, and BuChE has emerged as a potential therapeutic target. In this study, we reported the development of compound 8e, a selective reversible BuChE inhibitor (eqBuChE IC₅₀ = 0.049 μmol/L, huBuChE IC₅₀ = 0.066 μmol/L), identified through extensive virtual screening and lead optimization. Compound 8e demonstrated favorable blood-brain barrier permeability, good drug-likeness property and pronounced neuroprotective efficacy. Additionally, 8e exhibited significant therapeutic effects in zebrafish AD models and scopolamine-induced cognitive impairments in mice. Further, 8e significantly improved cognitive function in APP/PS1 transgenic mice. Proteomics analysis demonstrated that 8e markedly elevated the expression levels of very low-density lipoprotein receptor (VLDLR), offering valuable insights into its potential modulation of the Reelin-mediated signaling pathway. Thus, compound 8e emerges as a novel and potent BuChE inhibitor for the treatment of AD, with significant implications for further exploration into its mechanisms of action and therapeutic applications.

Ischemic stroke,due to its high prevalence and mortality,has become one of the most important public health concerns globally.Nerve cell damage is the main biological event in its patho-logical process and there is still a lack of effective neuroprotective drugs for clinical use.Numerous studies have shown that inhibitions of histone deacetylases(HDACs)can exert neuroprotective effects in ischemic stroke.Due to the multiple types of HDACs and the relatively poor specificity of HDAC inhib-itors,it has been difficult to identify any HDAC that plays a key role in ischemic stroke.ClassⅠHDACs include four members:HDAC1,HDAC2,HDAC3,and HDAC8,and have been more in-depth in isch-emic stroke.The complex mechanisms of classⅠHDAC inhibitors that have been discovered so far involve neural cell function,neuroinflammation and blood-brain barriers.This article is intended to study the regulatory role of classⅠHDACs in ischemic stroke in the hopes of providing reference for the developments of effective drugs targeting HDACs.

Objective To investigate the pathological damage to and inflammation of different intestinal segments in a rat model of severe hemorrhage,and to explore the effect of polarization of intestinal macrophage on the pathophysiology of intestinal inflammation.Methods Male Wistar rats were randomly divided into two groups:the sham operation group and hemorrhage group.In the hemorrhage group,40％of the total blood volume was lost in 25-30 minutes,while in the sham operation group,only the femoral artery and vein were intubated without bleeding.The rats were killed at 0,3,6,12 and 24 hours.The entire intestine was isolated quickly,and sections of the intestine were cut at the duodenum,jejunum,ileocecal junction,colon and rectum for histopathological evaluation.ELISA was adopted to determine related inflammation factors while multi-color immunohistochemistry was used to calculate macrophage surface markers.The data was statistically analyzed.Results(1)Compared with the sham group,there was no significant difference in colon histology at 3 h and 6 h,but significant difference was detected in rectum scores only at 24 h.The scores of other intestinal segments were significantly different at each time point.The severity of ileocecal and colonic lesions after bleeding increased with time.The duodenum,jejunum and ileocecum were more critically injured at 3 h than the rectum at 6 h.The injury to the duodenum,jejunum,ileum and colon was much more pronounced than to the rectum at 12 h.(2)The expressions of TNF-α and IL-1β in the rectum were increased significantly at 12 h post operation.The expressions of IL-1β,TNF-α in the jejunum increased obviously at 3 h and 6 h,respectively.(3)Three hours after severe bleeding,the level of macrophages in the jejunum and ileocececal area increased significantly,and the percentage of M1 macrophages was higher.After 6 hours,the proportion of M2 macrophages in the jejunum and M1 macrophages decreased significantly.After 3 hours,the percentage of M1 macrophages in the colon decreased,but that of M2 macrophages increased.The proportion of M2 polarized macrophages in the duodenum and rectum increased at 3 h after severe bleeding but decreased at 6 h.Conclusion Pathological damage to intestinal sections after bleeding varies depending on the time,and is correlated with the inflammatory level of macrophages.

Objective:To analyze the efficacy and safety of tislelizumab in the treatment of advanced gastric cancer.Methods:The clinical data of 54 patients with advanced gastric cancer in Baotou Cancer Hospital from July 2022 to December 2023 were retrospectively analyzed. Among them, 27 patients were treated with chemotherapy (control group), and 27 patients were treated with tislelizumab combined with chemotherapy (combination group). The efficacy was evaluated after 2 cycles. The patients were followed up until March 2024, and the survival status was evaluated by progression-free survival (PFS) and duration of remission (DOR). The adverse reactions were recorded. Kaplan-Meier survival curve was drawn, and the compared used log rank test. Binary Logistic regression was used to analyze the independent risk factors of efficacy in patients with advanced gastric cancer.Results:The effective rate and disease control rate in combined group were significantly higher than those in control group: 29.6% (8/27) vs. 7.4% (2/27) and 85.2% (23/27) vs. 59.3% (16/27), and there were statistical differences ( χ2 = 4.42 and 4.52, P<0.05). Kaplan-Meier survival curve analysis result showed that the median PFS and DOR in combination group were significantly longer than those in control group (9.9 months vs. 7.2 months and 8.7 months vs. 6.4 months), and there were statistical differences (log-rank χ2 = 6.58 and 8.47, P<0.05). Among the 54 patients, 10 cases (18.5%) were effective, and 44 cases (81.5%) were ineffective. The efficacy was related to the number of organ metastase, prealbumin and Helicobacter pylori infection rate, and there were statistical differences ( P<0.05). Binary Logistic regression analysis result showed that the number of organ metastase >1, prealbumin <160 mg/L and Helicobacter pylori infection were independent risk factors of efficacy in patients with advanced gastric cancer ( OR = 0.089, 8.418 and 0.153; 95% CI 0.012 to 0.661, 1.255 to 56.449 and 0.025 to 0.944; P<0.05). There was no statistical difference in the incidence of adverse reactions between two groups ( P>0.05). Conclusions:The tislelizumab combined with chemotherapy in patients with advanced gastric cancer can improve the efficacy and prolong the survival without increasing the incidence of adverse reactions.

Objective To investigate the cognition of colorectal cancer-related knowledge and influencing factors of patients with middle- and advanced-stage colorectal cancer in ethnic minority areas of Inner Mongolia. Methods According to the national population and the prevalence of colorectal cancer, 277 patients with colorectal cancer were selected by stratified and random sampling in Inner Mongolia. The patients were surveyed in Baotou, Chifeng, Bayannaoer, and other hospitals. The questionnaire included patients' basic information, cognition of colorectal cancer risk factors and screening knowledge, screening information, etc. Results Before suffering from the disease, the patients' knowledge of colorectal cancer (risk factors, early screening knowledge, treatment methods) was low. About 54.9% of patients were unaware of high risk factors for colorectal cancer, 75.8% of patients did not understand the knowledge of early screening of colorectal cancer, and 37.5% of patients did not underst and the treatment of colorectal cancer. The main influencing factors of colorectal cancer cognition were education level and occupation. Patients who work in institutions and enterprises and with higher education level had better cognition. Conclusion Patients with middle- and advanced-stage colorectal cancer in Inner Mongolia have poor knowledge and awareness of risk factors and screening of colorectal cancer before diagnosis. Education level and occupation are factors influencing colorectal cancer cognition, therefore, people with low knowledge rate of colorectal cancer and low education level as well as unemployed laid-off people should be given priority intervention.

Objective Based on the gene expression omnibus(GEO)database,bioinformatics methods were employed to analyze the expression characteristics of hypoxia-related differentially expressed genes(HRDEGs)in ischemic stroke,and key genes were screened,to provide important support for a deeper understanding of ischemic stroke.Methods The GSE16561 and GSE58294 datasets were downloaded from the GEO database,and Python software was used for data integration.The Combat method was employed to eliminate batch effects while retaining disease grouping characteristics.Principal component analysis was conducted to reduce dimensionality of the data before and after batch effect removal,and intraclass correlation coefficient(ICC)testing was performed on the ischemic stroke and normal control groups.Gene set enrichment analysis(GSEA)and single-sample GSEA were conducted on the merged and batch effects eliminated dataset,with a nominal P-value(NOM P-val)＜0.05 and false discovery rate P-value(FDR P-val)＜0.25 used as criteria to select significantly different gene sets.Differential expression genes between the ischemic stroke samples and normal control samples after merging and eliminating batch effects of the GSE16561 and GSE58294 datasets were identified using R software,with an absolute value of log2 gene expression fold change(FC)≥0.58 and adjusted P-value(Padj)＜0.05 as selection criteria.Intersection with hypoxia-related genes obtained from the National Center for Biotechnology Information(NCBI)in the United States yielded the HRDEGs.Gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)enrichment analyses were performed on the HRDEGs,and the STRING database was used to construct a protein-protein interaction network of differentially expressed genes.The top 10 key genes were filtered using Cytoscape 3.8 software.Results The ICC analysis results showed excellent consistency in the ischemic stroke and normal control samples after batch effect removal,with ICC values of 0.94 and 0.98 for the GSE16561 and GSE58294datasets,respectively.GSEA results demonstrated significant enrichment of 34 gene sets in the stroke samples in the newly merged and batch effects removed dataset from GSE16561 and GSE58294,leading to the identification of 404 differentially expressed genes(all with Padj＜0.05),including 354 upregulated genes and 50 downregulated genes.Intersection with hypoxia-related genes yielded 64 HRDEGs.GO enrichment analysis indicated significant enrichment of HRDEGs in vesicle lumen,cytoplasmic vesicle lumen,secretory granule lumen,with molecular functions such as amide binding,peptide binding,phospholipid binding,and enzyme inhibitor activity.These genes are primarily involved in the positive regulation of cytokine production,regulation of immune response,response to bacterium-derived molecules,and response to lipopolysaccharide,among other biological processes.KEGG enrichment analysis revealed enrichment of HRDEGs in pathways related to lipid and atherosclerosis,Salmonella infection,neutrophil extracellular trap formation,nucleotide-binding oligomerization domain-like receptor signaling pathway,protein glycosylation in cancer,tuberculosis,and necroptosis.Based on the protein-protein interaction network,10 key genes were identified,including arginase1(ARG1),caspase1(CASP1),interleukin1 receptor type 1(IL-1R1),integrin subunit alpha M(ITGAM),matrix metalloproteinase9(MMP9),prostaglandin-endoperoxide synthase 2(PTGS2),signal transducer and activator of transcription 3(STAT3),Toll-like receptor2(TLR2),TLR4,and TLR8.Conclusion This study has identified 10 key genes associated with ischemic stroke and hypoxia through bioinformatics mining,which maybe provid potential targets for subsequent research and diagnostic and therapeutic interventions.

Objective:To understand the prevalence of insufficient physical activity among adults aged ≥18 years in China and to explore the influencing factors.Methods:The China Chronic Disease and Risk Factor Surveillance was conducted in 298 counties/districts in China in 2018, covering 31 provinces (autonomous regions, municipalities). A multi-stage stratified cluster random sampling method was used to select permanent residents aged ≥18 years. A questionnaire including Global Physical Activity Questionnaire was used to collect information about the participants' demographic characteristics and physical activity through face-to-face interview. A total of 183 769 participants completed the survey. After complex data weighting, the prevalence of insufficient physical activity, occupation, transportation, and leisure-time physical activity time was analyzed. Multivariate logistic regression models were used to analyze the influencing factors related to insufficient physical activity.Results:The prevalence of insufficient physical activity among adults aged ≥18 years was 22.3% (95% CI: 20.9%-23.7%) in China in 2018, with males [24.4% (95% CI: 23.0%-25.8%)] significantly higher than females [20.2% (95% CI: 18.6%-21.8%)]. Adults aged 70 years and above [28.4% (95% CI: 26.9%-29.9%)] were significantly higher than adults in other age groups, followed by adults aged 18-29 years [26.4% (95% CI: 24.4%- 28.3%)] and 30-39 years [23.4% (95% CI: 21.5%-25.3%)], and tended to increase with increasing education and total sedentary behavior time ( P<0.001). The weekly occupation, transportation, and leisure-time physical activity time appeared 958.6 (95% CI: 911.4-1 005.8) minutes, 234.5 (95% CI: 224.7- 244.2) minutes, and 88.6 (95% CI: 83.5-93.7) minutes, respectively. Multivariate logistic regression analysis showed that males, adults living in rural areas or northern China, ≥70 years, with junior high school education, an annual household income per capita <6 000 yuan and institutional/clerical/ technical occupation and longer total sedentary behavior time were related to a higher prevalence of insufficient physical activity. Conclusions:In China, over one-fifth of the adults had lower physical activity levels. Adults who are male, young adults, more educated, institutional/clerical/technical occupation, and with more extended total sedentary behavior are the populations that need to be focused on to promote physical activity-related health.

Objective To investigate the protective effects of astragalosides Ⅳ (ASI) on high glucose-induced renal proximal tubular epithelial cells (NRK-52E).Methods NRK-52E were cultured and divided randomly into three groups:control group,high glucose group (HG in short),ASI groups (with various doses).Cells were treated with increasing concentrations of ASI (20,40,80 and 100 μg/ml) for 24 h in high glucose and we also stimulated cells in ASI 100 μg/ml with high glucose for various lengths of time.The apoptosis rate was detected by flow cytometric analysis.The mRNA and protein expression of transforming growth factor-β1 (TGF-β1),a-smooth muscle actin (α-SMA),Smad2,Smad3 and their phosphorylated forms were detected by real-time polymerase chain reaction (PCR) and Western blot,respectively.Results Compared with the control group,apoptosis was increased in the high glucose group (P ＜ 0.01).However,ASI inhibited high glucose-induced cell apoptosis in a dose-dependent manner,with a maximal inhibitory effect achieved at 100 μg/ml (P ＜ 0.05).The significant inhibition caused by ASI was observed at 8h after the start of pretreatment (P ＜ 0.05) and increased in a time-dependent manner.ASI can inhibit the expression of TGF-β1,α-SMA,Smad2,Smad3 both at mRNA and protein level.Conclusions ASI inhibited NRK-52E cells apoptosis induced by high glucose and reduced expression of TGF-β1,α-SMA,Smad2,Smad3 both at the mRNA and protein level in NRK-52E cells,thus delayed epithelial-to-mesenchymal transition progress.
