Background: and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture. Methods: A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture. Results: The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05). Conclusion The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

Background::Thoracic aortic aneurysm (TAA) is a fatal cardiovascular disease, the pathogenesis of which has not yet been clarified. This study aimed to identify and validate the diagnostic markers of TAA to provide a strong theoretical basis for developing new methods to prevent and treat this disease.Methods::Gene expression profiles of the GSE9106, GSE26155, and GSE155468 datasets were acquired from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were identified using the "limma" package in R. Least absolute shrinkage and selection operator (LASSO), support vector machine-recursive feature elimination (SVM-RFE), random forest, and binary logistic regression analyses were used to screen the diagnostic marker genes. Single-sample gene set enrichment analysis (ssGSEA) was used to estimate immune cell infiltration in TAA.Results::A total of 16 DEGs were identified. The enrichment and functional correlation analyses showed that DEGs were mainly associated with inflammatory response pathways and collagen-related diseases. Collagen type I alpha 1 chain ( COL1A1) and synaptotagmin like 2 ( SYTL2) were identified as diagnostic marker genes with a high diagnostic value for TAA. The expression of COL1A1 and SYTL2 was considerably higher in TAA vascular wall tissues than in the corresponding normal tissues, and there were significant differences in the infiltration of immune cells between TAA and normal vascular wall tissues. Additionally, COL1A1 and SYTL2 expression were associated with the infiltration of immune cells in the vascular wall tissue. Single-cell analysis showed that COL1A1 in TAA was mainly derived from fibroblasts and SYTL2 mainly from cluster of differentiation (CD)8 + T cells. In addition, single-cell analysis indicated that fibroblasts and CD8 + T cells in TAA were significantly higher than those in normal arterial wall tissue. Conclusions::COL1A1 and SYTL2 may serve as diagnostic marker genes for TAA. The upregulation of SYTL2 and COL1A1 may be involved in the inflammatory infiltration of the vessel wall and poor extracellular matrix remodeling, promoting the progression of TAA.

AIM:To investigate the activation of Cl-channels by sodium taurocholate(NaTC)in mouse pan-creatic acinar cells.METHODS:The single isolated pancreatic acinar cells from FVB/N mice were prepared using colla-genase digestion method.Whole-cell patch clamp technique was performed to record the currents.Intracellular adenosine triphosphate(ATP)dependence of the channels was examined via eliminating ATP from the pipette solution.Anion per-meability of the channels was investigated with ion-exchange method.The pharmacological characteristics of the channels was confirmed by two Cl-channel blockers.The volume sensitivity of the channels was detected using 47%hypertonic bathing solution.Extracellular Ca2+dependence of activating the channels was examined through eliminating Ca2+from the bathing solution.Intracellular reactive oxygen species(ROS)level was detected by an oxidation-sensitive fluorescent probe,2',7'-dichlorofluorescin diacetate.The experiment was repeated 6 times in each group.RESULTS:Extracellular application of 5 mmol/L sodium taurocholate induced a Cl-current,exhibiting the properties of outward-rectification,a se-lectivity sequence of I->Br-≥Cl->gluconate-and intracellularATP dependence(P<0.01).The currents were inhibited by chloride channel blocker 4,4'-diisothiocyanatostilbene-2,2'-disulfonic acid disodium salt hydrate(DIDS)and tamoxifen and by 47%hypertonicity stimulation(P<0.01).When ROS production was scavenged by N-acetyl-L-cysteine,the sodi-um taurocholate-induced Cl-currents were unaffected.The effect of sodium taurocholate on ROS production did not alter with the treatment with DIDS.Sodium taurocholate failed to induce Cl-currents when Ca2+was absent in extracellular bath-ing solution(P>0.05).CONCLUSION:Sodium taurocholate activates Cl-channels in mouse pancreatic acinar cells,which is dependent on extracellular Ca2+but not ROS pathway.

ObjectiveThe correlation of Pueraria lobata producing areas， climate factors， total flavonoids of P. lobata， polysaccharide content of P. lobata， and antioxidant activity of P.lobata for medicinal application was analyzed， and the relationship between climate factors and the formation of P. lobata quality was evaluated. MethodThe scavenging rates of 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl（DPPH） and 2, 2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)（ABTS） radicals by total flavonoids and polysaccharides of P. lobata were detected， and the correlation between the contents of each component and the information of producing areas and climate factors was analyzed. ResultThe ABTS⁺ scavenging rate by total flavonoids of P.lobata was negatively correlated with altitude （P<0.05） and positively correlated with annual sunshine hours （P<0.05）. The altitude was positively correlated with the total flavonoid content， while the annual sunshine hours were negatively correlated with the total flavonoid content. There was a negative correlation between total flavonoid content and ABTS⁺ scavenging rate by total flavonoids. In other words， lower altitude and longer annual sunshine hours indicated lower total flavonoid content and higher ABTS⁺ scavenging rate by total flavonoids. The ABTS⁺ scavenging rate by polysaccharides of P. lobata was negatively correlated with the frost-free period （P<0.05） and the mean temperature in July （P<0.01）. There was a positive correlation between the polysaccharide content of P. lobata and the frost-free period. The mean temperature in July was positively correlated with the polysaccharide content of P. lobata （P<0.05）. The polysaccharide content of P. lobata was negatively correlated with the ABTS⁺ scavenging rate by polysaccharides of P. lobata. In other words， a shorter frost-free period in the producing area and lower mean temperature in July indicated lower polysaccharide content of P. lobata and higher ABTS⁺ scavenging rate by polysaccharides of P. lobata. The mean temperature in July was significantly correlated with the contents of total flavonoids and polysaccharides in P. lobata samples （P<0.05）. The lower mean temperature in July was often accompanied by lower total flavonoid content of P. lobata， lower polysaccharide content of Pueraria lobata， and stronger antioxidant activity of P. lobata samples. ConclusionThe ability of P. lobata to remove ABTS⁺ is stronger than that of DPPH⁺. There is a significant correlation between climate factors， content， and antioxidant capacity in each producing area. Further research on the internal law of the formation of medicinal active components of P. lobata induced by core climate factors will provide a scientific basis for revealing the formation mechanism of genuine P. lobata and the subsequent control of P. lobata quality according to the environment of producing areas.
