Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

Neuroinflammatory responses play an important role in the pathogenesis of various diseases, particularly those affecting the central nervous system. Inhibition of neuroinflammation is a crucial therapeutic strategy for the management of central nervous system disorders. The intestinal microbial-gut-brain axis serves as a key regulatory pathway that modulates neuroinflammatory processes. Intestinal flora metabolites such as short-chain fatty acids, indoles and their derivatives, lipopolysaccharides, trimethylamine oxide, and secondary bile acids exert direct or indirect effects on neuroinflammation. Studies have shown that electroacupuncture (EA) modulates the composition of the intestinal microbiota and its metabolites, while also suppressing neuroinflammation by targeting the TLR4/NF- κ B, NLRP3/caspase-1, and microglial cell M2-type transformation pathways. This review discusses the mechanisms by which EA regulates neuroinflammation via intestinal microbiota and its metabolites, providing information and a foundation for further investigation of the precise therapeutic mechanisms of EA in neurological disorders.

Objective To observe the multi-system toxicity of Tripterygium glycosides tablets in rats with type Ⅱ collagen-induced arthritis(CIA).Methods Healthy SD rats were randomly divided into normal group,model group and experimental group,with 10 rats in each group.In addition to the normal group,the other groups were established collagen-induced arthritis model.After the first immunization,the normal group and the model group were given an equal volume of 0.3％sodium carboxymethyl cellulose solution,and the experimental group was given 72 mg·kg-1·d-1 Tripterygium glycosides solution,once a day for 6 weeks.On the 42 nd day,the blood routine of each group was detected and the organ index was calculated.The levels of liver,kidney function and sex hormones in rats were detected by enzyme-linked immunosorbent assay.The histopathological changes of liver,kidney,ovary and testis were observed by hematoxylin-eosin(HE)staining.Results The testicular indexes of the normal group,the model group and the experimental group were(0.81±0.05)％,(0.97±0.06)％and(0.81±0.12)％;the estradiol contents were(63.90±16.19),(55.42±7.23)and(40.04±5.97)pg·mL-1;the testosterone contents were(1 290.96±257.94),(1 198.43±190.77)and(912.62±61.72)pg·mL-1,respectively.There were statistically significant differences in the above indexes between the model group and the experimental group(P＜0.01,P＜0.05).HE pathological results showed that Tripterygium glycosides tablets could cause abnormal histopathological changes of ovary and testis in CIA model rats.Conclusion Continuous administration of 8-fold clinical equivalent dose of Tripterygium glycosides tablets for 6 weeks can cause damage to the reproductive system of CIA rats.

Objective:To analyze the expression of B-cell development-related genes in acute B lymphoblastic leukemia (B-ALL),and to explore the relationship between B-cell development-related genes and the prognosis of B-ALL patients.Methods:The GEO and TARGET databases were integrated to analyze the differential expression of B-cell development-related genes between the healthy persons and B-ALL patients and their differential expression in the B-ALL relapse and non-relapse groups.Cox single factor regression and Lasso regression were used to constructe a B-ALL specific prognosis model of B-cell development-related genes.The prognostic value of this model was analyzed by Cox multiple factor regression.The risk scores of different subtypes of B-ALL was analyzed.In the real world,the correlation between the prognostic model of B-cell development-related genes and clinical outcomes was verified through the transcriptome sequencing results of B-ALL patients.In addition,the correlation between this prognostic model and other B-ALL prognostic models was also analyzed.At last,Metascape was used to evaluate the pathway and function enrichment status related to the prognosis model.Results:There were 1097 genes specifically expressed in B-ALL and related to B cell development,27 of which were up-regulated in the B-ALL relapse group,and 37 genes were down-regulated in the B-ALL relapse group.14 genes were further selected to be included in the B-cell development-related prognosis model (CDC25B,CKAP4,DSTN,IGF2R,NDUFA4,ODC1,PAX5,SH3BP4,SLC27A5,APAF1,ARRB2,HHEX,IL13RA1,UVRAG)based on Cox single factor regression and Lasso regression.Risk scoring of patients with B-ALL based on the 14 genes prognosis model,the prognosis of 134 patients in the low-risk scoring group (score>0.11) was better than those in the patients with high-risk scores (score≤0.11 ).Multivariate analysis showed that the risk score of B-cell development-related genes was an independent prognostic factor.And the proportion of hyperdiploid positive children in the low-risk scoring group was significantly higher than that in the high-risk scoring group,while the proportion of TCF3/PBX1 positive children in the high-risk scoring group was significantly higher than that in the low-risk scoring group.At the same time,the real-world data showed that the prognosis of patients with B-ALL in the high-risk scoring group was worse than those of the patients with low-risk scores in Xi'an Children's Hospital.And the risk score of B-cell development-related genes in patients with B-ALL death was higher than that in patients with B-ALL non-death.In addition,there is a positive correlation between the risk score calculated by the metabolic-related gene prognostic scoring system and the risk score calculated by the B-cell developmental-related gene prognostic model.At last,differential gene enrichment analysis suggested that the prognosis risk was related to the process of embryonic development and differentiation to various systems,especially to the B cell receptor signaling pathway.Conclusion:The specific expression of B-cell development-related genes in B-ALL is related to the prognosis of B-ALL.The prognosis model composed of 14 genes is expected to be a new prognostic marker for children with B-ALL.

Objective:To analyze and compare the differences of expression profiles between RPL and normal adipose tissue by transcriptome sequencing(RNA-Seq),then identify the key genes related to prognosis and explore their potential mechanisms.Methods:Tumor tissues and normal adipose tissues of patients with RPL were collected for RNA-Seq,and then the differentially ex-pressed genes were analyzed by GO and KEGG enrichment analysis.Based on TCGA,the high-risk genes related to prognosis were screened and verified by Kaplan-Meier curve and receiver operat-ing characteristic(ROC)curve.Results:Compared with normal adipose tissue,279 differentially expressed genes were simultaneously up-regulated in RPL tissues,which were mainly enriched in immune response and PPAR signaling pathway.Combined with TCGA,7 stable prognostic high risk genes were identified and the overall survival rate of the high risk group was significantly lower than that of the low risk group(P＜0.05).Conclusion:KCNQ5,RBPJ and some other genes may be re-lated to the poor prognosis of RPL patients.The analysis of the mechanism of these genes in RPL is expected to provide new evidence for the formulation of diagnosis and treatment strategies for RPL patients.
