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.

The glymphatic system(GS)is a unique toxic sub-stance clearance system in brain,which is very important for maintaining the microenvironment stability of the central nervous system.The polarization distribution of aquaporin 4(AQP4)lo-cated in the terminal foot of astrocytes affects the function of GS and participates in the pathological progress of many neurodegen-erative diseases,but the detailed regulation mechanism of AQP4 polarization distribution has not been systematically summarized.Therefore,this paper systematically combs the mechanism of reg-ulating the polarization distribution of AQP4 from the perspective of the composition integrity of dystrophin-glycoprotein complex(DGC)and basement membrane foot complex,and summarizes the potential drug and non-drug therapies for targeted regulation of AQP4 polarization distribution at present,aiming at providing new target reference and theoretical basis for targeted regulation of AQP4 polarization to prevent and treat neurodegenerative dis-eases.

Objective:To analyze the imaging features of testicular conventional ultrasonography（US），shear wave elastography（SWE），and contrast-enhanced ultrasonography（CEUS）in subtypes of spermatogenic dysfunction（focal，arrest，and exhausted），and to evaluate the diagnostic efficacy of testicular multimodal ultrasound.Methods:A prospective study enrolled 310 spermatogenic dysfunction patients（focal type group： n=77，arrest type group： n=20，exhaustive type group： n=213）and 30 healthy volunteers（control group）at Shanghai General Hospital between October 2023 and December 2024. All patients underwent preoperative testicular US，SWE，and CEUS examinations，followed by microdissection testicular sperm extraction. Ultrasound parameters were compared among groups，and receiver operating characteristic（ROC）curves were plotted to assess the diagnostic efficacy of multimodal ultrasound for different subtypes. Results:①Testicular volume：The arrest group exhibited significantly greater volume compared to the focal group and the exhausted group（all P<0.05）. No statistically significant difference was observed between the arrest group and the normal group（ P>0.05）. ②Mean Young's modulus（Emean）：The arrest group exhibited significantly lower Emean compared with both the focal and exhausted groups（all P<0.05），but showed no significant difference versus the normal group（ P>0.05）. ③CEUS quantitative parameters：The arrival time（AT）and time to peak（TTP）in the exhausted group were higher than those in the normal group，while the peak intensity（PI）and area under the time-intensity curve（AUC）were lower（all P<0.05）. No significant differences were found in AT，TTP，or AUC among the three spermatogenic dysfunction subgroups（all P>0.05）. ④CEUS perfusion patterns：The focal group predominantly exhibited a mottled pattern（70.13%，54/77）. Both the arrest group（90.00%，18/20）and the normal group（93.33%，28/30）predominantly exhibited an rich pattern. The exhausted group predominantly exhibited a sparse pattern（56.34%，120/213）. ⑤ROC curve analysis showed that for differentiating the arrest group from the focal type group and the exhaustive type group，the combination of Emean，testicular volume，and CEUS perfusion pattern yielded an AUC of 0.931，with a sensitivity of 95.00% and specificity of 85.86%. For differentiating the focal type group from the exhaustive type group，the combination of testicular echogenicity，CEUS perfusion pattern，and Emean yielded an AUC of 0.833，with a sensitivity of 81.82% and specificity of 75.12%. Conclusions:Multimodal ultrasonography can comprehensively characterize the imaging features of different subtypes of spermatogenic dysfunction，holding promise as a noninvasive predictive tool.
