Objective To explore the casual relationship between immune cells and chronic pancreatitis(CP)using Mendelian randomization(MR)analysis.Methods The immune cell phenotypes and CP GWAS data used in this study were obtained from public databases,and 731 immune cell phenotypes were included.The bidirectional MR analysis was used to explore the causal relationship between immune cells and CP,and various sensitivity analysis methods were used to verify the heterogeneity and level multiplicity of the results.Results This study identified 33 immune cell phenotypes with a causal relationship with CP,of which 18 were inhibitory factors,and the rest were risk factors.Among the 18 inhibitory factors,CD25 on CD4+in the Treg cell group showed the most significant inhibitory effect.Among the 15 risk factors,CD8br AC in the TBNK cell group,CD8br on TD CD8br in the mature T cell group,and CD39+CD8br％ T cell and CD28 on CD4+in the Treg cell group showed statistical significance.The reverse MR results further confirmed the unidirectionality of the causal relationship.Conclusion Our study revealed the close relationship between immune cells and CP through MR method,highlighting the complex interaction pattern between the immune system and CP.

Objective:To evaluate the causal relationship between autism spectrum disorder (ASD) and chronic pancreatitis (CP) using a bidirectional two-sample Mendelian randomization (MR) analysis.Methods:Based on genome-wide association study (GWAS) data, forward and reverse two-sample MR analyses were conducted to examine the causal relationship between ASD and CP. Single-nucleotide polymorphisms (SNPs) reaching genome-wide significance were selected from the GWAS data as candidate instrumental variables, and the Steiger directionality test was used to confirm the causal direction. The inverse-variance weighted (IVW) method was applied as the primary analysis to estimate the causal effect of the exposure on the outcome. MR-Egger regression and weighted median methods were used as supplementary sensitivity analyses to assess the robustness of the results. Pleiotropy and heterogeneity tests were performed to evaluate the reliability of the findings.Results:The forward MR analysis ultimately identified 29 SNPs. The IVW analysis indicated that ASD had a significant positive causal effect on CP risk ( OR=1.197, 95% CI 1.047-1.368, P=0.008), with no evidence of horizontal pleiotropy or significant heterogeneity. In the reverse MR analysis, 17 SNPs were included; the IVW analysis did not detect a significant causal effect of CP on ASD ( OR=0.990, 95% CI 0.935-1.047, P=0.717), also with no evidence of horizontal pleiotropy or significant heterogeneity. Causal effect estimates from MR-Egger regression and weighted median analyses were generally consistent with those of IVW. Conclusions:These findings indicate that, at the level of genetic susceptibility, ASD is a risk factor for CP.

【Objective】 To explore the causal relationship between education level and pancreatitis risk through Mendelian randomization. 【Methods】 A two-sample Mendelian randomization analysis was conducted using genome-wide association study (GWAS) summary data. The GWAS data for education level and pancreatitis were obtained from SSGAC database and the FinnGen database (version R9). Causal relationship between education level and pancreatitis was explored using the inverse variance weighted (IVW), MR-Egger, and weighted median methods. Heterogeneity and directional pleiotropy were evaluated using Cochran’s Q test and funnel plots. 【Results】 Totally 604 SNPs associated with education level were included. The results provided evidence that there was negative relationship between education level and pancreatitis risk. For acute pancreatitis, OR=0.52, 95% CI: 0.44-0.62, P=2.43×10^-14 while for chronic pancreatitis, OR=0.51, 95% CI: 0.41-0.64, P=7.20×10^-9. Results from MR-Egger and weighted median analyses obtained the same results. The results of sensitivity analysis indicated that this study did not violate the basic assumptions of Mendelian randomization. 【Conclusion】 There is a causal relationship between education level and the occurrence of pancreatitis. The educational level is negatively correlated with the risk of pancreatitis.

Objective To explore and verify the protective and therapeutic effects and possible mechanisms of Zukamu granules on hypoxia alone and hypoxia+Su5416-induced hypoxic pulmonary hypertension(HPH)in mice.Methods Multiple databases and related literature were used to collect the active ingredients data in Zukamu granules and the HPH-related targets were predicted and obtained.The network construction and enrichment analysis were performed.The HPH mouse models were es-tablished by two-week hypoxia and four-week hypoxia+Su5416 induction,and the relevant indicators and the main pharmacodyna-mic indexes such as right ventricular pressure were tested.Masson staining was used to observe the pathological changes in lung tissues,and Western blotting was used to detect the expression levels of bax,bcl-2,PI3K,p-PI3K,eNOS,and HIF-1α in lung tis-sues.Results A total of 167 active ingredients of Zukamu granules were screened,with 179 intersecting targets with HPH,in-cluding targets like PIK3CA and HIF-1.The validation experimental results showed that Zukamu granules could significantly re-duce right ventricular systolic pressure and right ventricular hypertrophy in HPH mice,and down-regulate the expression of bcl-2 and HIF-1α and up-regulate the expression of bax,PI3K,p-PI3K and eNOS in mice lung tissues.Conclusion Zukamu gran-ules may act against HPH by modulating bax/bcl and PI3K-eNOS/HIF-1α signaling pathways.
