Objective To evaluate the efficacy of minimally invasive neuroendoscopy combined with intraventricular drainage in the treatment of intraventricular hemorrhage.Methods A retrospective analysis was conducted on the clinical data of 88 patients with intraventricular hemorrhage who underwent surgical treatment from January 2018 to December 2023.All patients received bilateral ventricular indwelling external drainage tubes.Among them,37 cases were included in the endoscopy group.The bleeding side or side with more blood accumulation underwent a midline fistula.With the assistance of neuroendoscopy,the intraventricular blood clots were removed and a ventricular drainage tube was inserted.The contralateral ventricle was punctured and a ventricular drainage tube was inserted;The remaining 51 cases were included in the drainage group,in which bilateral ventricular drainage tubes were placed according to the traditional intraventricular drainage protocol.Results There was no significant statistical difference(P>0.05)between the endoscopic group and the drainage group in terms of mortality rate(10.8%vs.13.7%),rebleeding rate(8.1%vs.11.8%,P=0.576),intracranial infection rate(10.8%vs.17.6%,P=0.372),and hydrocephalus rate(10.8%vs.23.5%,P=0.166).Similarly,no significant statistical difference was found in the total hospitalization cost between the endoscopy group and the drainage group[(90700±73000)yuan vs.(99500±66000)yuan]and the GOS score during the 6-month follow-up(3.16±1.14 vs 3.02±1.12)showed(P>0.05).However,the postoperative GCS score improvement was significantly better in the endoscopic group than in the drainage group[2.00(2.00,4.00)vs.1.00(0.00,3.00),P=0.002].The duration of the extracranial drainage catheter placement was significantly shorter in the endoscopic group than in the drainage group[(7.16±2.99)days vs.(10.12±3.93)days,P<0.001].Conclusion Neuroendoscopy-assisted evacuation of intraventricular hemorrhage facilitates effective hematoma clearance,reduces the duration of ventricular drainage catheterization,and may contribute to improved patient outcomes.

Drug addiction,also referred to as drug dependence or substance use disorder,is a chronic and recurrent brain disease.Its main characteristics are compulsive drug-seeking behavior,continued use of drugs,and a loss of control over intake.Prolonged use of addictive substances can result in both physiological and psychological dependence.When usage is ceased,individuals may experience intense discomfort,including anxiety,insomnia,nausea,vomiting,and a strong craving for the substances.Drug dependence is classified into two types:physical dependence and psychological dependence.Physical dependence describes a pathological state of adaptation that results from the repeated use of addictive substances,leading to severe withdrawal syndrome upon cessation.Psychological dependence involves a mental craving for addictive substances,which is needed to experience the specific euphoria that follows consumption.Regular or continuous use is required to sustain these euphoric effects.The mechanisms of addiction are complex and influenced by genetic,environmental,and various other factors.They involve higher-level neurological activities,such as memory,reward,and decision-making.Currently,effective treatment methods for drug addiction are insufficient.Due to the complexity of drug addiction,laboratory animal research is essential.Using animal behavioral models to simulate human drug addiction can enhance our understanding of the mechanisms of addiction.This research offers a comprehensive overview of various animal experimental models that explore both physical and psychological dependence.It includes detailed descriptions of the methods and procedures used to assess physical dependence,behavioral sensitization,conditioned place preference,drug discrimination,and self-administration experiments.Additionally,the characteristics of each experimental model are compared,and the relevance of these models is discussed,aiming to provide support for the research on addiction mechanisms and the development of therapeutic methods.

Objective:To analyze the mediating effect of cardiovascular health status (CVH) on the association between educational level and cardiovascular disease (CVD).Methods:The participants were from Shanghai Suburban Adult Cohort and Biobank, and questionnaire survey, physical examination, blood biochemistry were conducted from 2016 to 2020 for baseline information collection, and follow up was conducted until March 31, 2024 based on the medical data, CVD incidence data and death surveillance data at different levels. The associations of educational level, CVH and time to CVD onset of the study population were analyzed using the accelerated failure time model to analyze the mediating effects of CVH, health behaviors, and health factors in the association of educational level and time to CVD onset. The mediating effects of educational level, gender, and age moderated associations were also analyzed.Results:A total of 57 312 participants were included, with 2 780 new cases of CVD during a median follow-up of 6.71 (6.71-6.72) years, and a mean incidence density of 7.77/1 000 person-years (95% CI: 7.48/1 000 person-years -8.06/1 000 person-years). In total, the less educational level and the lower CVH, the higher CVD incidence density ( P<0.05). The results of accelerated failure time models showed that the time ratio for CVD-free survival was 1.15 (95% CI: 1.06-1.24) and 1.33 (95% CI: 1.10-1.60) for moderate and high educational level, respectively. The results of the mediation effect analysis showed that the association between moderate and high educational level and time to CVD onset was 29.60% (20.50%-50.00%) and 36.10% (23.80%-59.00%), 9.97% (5.07%-20.00%) and 13.84% (6.84%-29.00%), 15.24% (9.64%-27.00%) and 17.55% (11.58%-33.00%) of mediators mediated by CVH, health behaviors, health factors, respectively. Among them, there was an exposure-mediated interaction of educational level and a positive moderating effect of age. Conclusion:CVH, health behaviors and health factors had a proportionate mediating effect in the association between educational level and risk of CVD development.

Guided by Zhang Zhongjing's axiom that"blood stasis induces water",this study develops stage-specific treatment strategies for edema in Kidney Consumption Disorder by examining its four-stage pathogenic progression:Sluggish Flow → Stagnant Obstruction → Depressed Accumulation → Stasis Congelation.We propose an integrated approach that reinforces the root by warming the kidney and replenishing essence,while addressing the branch by activating blood circulation and promoting diuresis.Stage-specific interventions include:for the Sluggish Flow Phase,warming and tonifying kidney Yang combined with unblocking Yang to promote uri-nation;for the Stagnant Obstruction Phase,warming the kidney and replenishing essence supported by activating blood circulation and freeing the collateral channels;for the Depressed Accumulation Phase,quickening blood and resolving stasis,regulating Qi and trans-forming turbidity,along with warming the kidney and strengthening essence;and for the Stasis Congelation Phase,expelling stagnant accumulations while simultaneously regulating essence and blood.This framework advances novel pattern-determined strategies for Kid-ney Consumption edema management.

Objective To map the genome-wide distribution profile of histone H3K27me3 modification in diffuse gastric cancer tissues,identify target genes regulated by H3K27me3,and primarily explore the potential mechanism of its modification reprogramming in the occurrence and development of the tumor.Methods Normal gastric mucosal tissues and diffuse gastric cancer tissues were harvested from the patients who underwent examinations or treatments in the departments of gastroenterology and gastrointestinal surgery of our medical center between 2021 and 2023.There were 14 patients in the normal group(6 males and 8 females,average age of 46 years)and 14 patients in the gastric cancer group(8 males and 6 females,average age of 63 years).Cleavage under target and tagmentation(CUT&Tag)technology was employed to capture genomic regions modified by H3K27me3,and analyze the reprogramming characteristics of these modifications.RNA sequencing data,data from high-throughput chromosome conformation capture(Hi-C)technology,and publicly available single-cell data were integrated to investigate the target genes regulated by the reprogramming of H3K27me3 modifications in diffuse gastric cancer cells.Results The quality of the CUT&Tag and RNA sequencing data met the standards required for subsequent analysis.Histone H3K27me3 modifications in normal gastric mucosa and diffuse gastric cancer tissues were primarily distributed in distal intergenic regions and intronic regions.In gastric cancer tissues,compared to normal tissues,there was significant reprogramming of H3K27me3 modifications,characterized by a marked reduction in overall H3K27me3 signal intensity.The loss of 2 912 H3K27me3 signal peaks might lead to the up-regulation of 822 tumor-associated genes.Among them,56 genes displayed the most significant up-regulation(fold change in signal intensity≥2,P<0.05),with notable enrichment in the mammalian target of rapamycin complex 1(mTORC1)signaling pathway.Specifically,the methionine transporter SLC7A5 and the cystine transporter SLC7A11 were found to have the highest expression levels in gastric cancer tissues.Single-cell data revealed that the abnormal overexpression of SLC7A11 in diffuse gastric cancer was primarily observed in tumor epithelial cells.Further validation using public data and immunohistochemical experiments confirmed the elevated expression of SLC7A11 in diffuse gastric cancer,which is associated with poor prognosis in gastric cancer patients.Conclusion The reprogramming of histone H3K27me3 modification is an important epigenetic characteristic in diffuse gastric cancer.Loss of H3K27me3 signal peaks may up-regulate the expression of SLC7A11 in diffuse gastric cancer cells,and thereby promote tumor progression.

Objective To map the super-enhancers remodeling of intestinal gastric cancer and reveal the tumor biological functions of the super-enhancers and the downstream target genes that may be activated.Methods A total of 31 normal gastric mucosal tissues,23 intestinal gastric cancer tissues and 9 intestinal gastric cancer organoids were collected from the Department of Gastroenterology of Army Medical Center of PLA from January to December 2022.Chromatin targeting histone H3K27ac modified chromatin targeting cleavage under targets and tagmentation(CUT&Tag)sequencing was conducted on above tissues.The remodeling profiles of super-enhancers in intestinal gastric cancer were analyzed and the key target genes were identified based on bioinformation tools.CRISPRi technology was used to intervene with the super-enhancers,the expression of target genes was detected with Western blotting,and the proliferation,migration and invasion abilities were detected by CCK-8 assay and Transwell chambers in the control group and the intervention group.Results There was a significant difference in the signal of super-enhancers between intestinal gastric cancer tissues and normal gastric mucosal tissues(P<0.05),and the active super-enhancers in cancer tissues may be involved in biological processes such as negative regulation of the immune system and cell adhesion.The expression of up-regulated cell migration-inducing protein(CEMIP)in tumor cells was regulated by the super-enhancers,and intervening the super-enhancers down-regulated the expression of CEMIP(P<0.05),and inhibited the cell proliferation,invasion and migration abilities of tumor cells(P<0.05).Conclusion Super-enhancer remodeling is observed in intestinal gastric cancer,and they can up-regulate the expression of CEMIP gene and promote the growth,migration and invasion of cancer cells.
