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.

ObjectiveTo analyze the prevalence of myopia among the primary school students in Shanghai, and to explore its relationship with sleep duration and sleep quality, providing references for precise myopia prevention. MethodsA cross-sectional survey and random sampling were employed. Between April and May 2023, a total of 1 889 students from grades 1 to 5 in Jiading District, Shanghai, were selected for vision testing and a questionnaire on children’s sleeping habits and relevant factors were conducted using the Children’s Sleep Habits Questionnaire (CSHQ) in Chinese. The relationship between myopia and sleep patterns was analyzed using chi-square tests and a multivariate logistic regression model. ResultsThe overall myopia rate among the primary school students in Jiading District, Shanghai, was 35.6%. The results of univariate analysis showed that in the myopia group, the incidences of sleep disturbance and sleep anxiety were lower compared to children without myopia, while the incidences of sleep continuity and parasomnias were higher than there in the non-myopia group (χ2=12.816, 10.292, 10.971, 3.917, all P<0.05). Additionally, among the elementary school students with an average daily sleep duration of less than 10 hours, the prevalence of myopia was higher. The multivariate logistic regression analysis revealed that factors such as being female (OR=1.291, 95%CI: 1.044‒1.597), higher grade levels (2nd grade: OR=2.174, 95%CI: 1.471‒3.212; 3rd grade:OR=3.850, 95%CI: 2.648‒5.598; 4th grade: OR=8.906, 95%CI: 6.154‒12.890; 5th grade: OR=12.299, 95%CI: 8.433‒17.937), having one parent (OR=2.250, 95%CI: 1.757‒2.881) or both parents(OR=3.623, 95%CI: 2.719‒4.827) with myopia, and parasomnias (OR=1.518, 95%CI: 1.065‒2.163) were associated with a higher detection rate of myopia. ConclusionThe prevalence of myopia is notably high among the primary school students in Jiading District, Shanghai, and there is an association between the occurrence of myopia and parasomnias.

Objective To investigate the effects of terahertz(THz)radiation on mouse testicular tissue and its potential molecular mechanisms.Methods A total of 125 male C57BL/6J mice(6~8 weeks old)were randomly divided into control group and low-,medium-and high-radiation power groups.The mice of the latter 3 groups were exposed to THz radiation at a frequency of 2.5 T,with an average power density of 38,115,or 318 mW/cm2,for 5 or 10 min.The detection time was immediately or 24 h after exposure.HE staining was used to observe pathological damage.ELISA was employed to detect the expression of inflammatory factors in testicular tissue.RNA-seq was utilized to detect the global changes of gene expression.The differentially expressed genes(DEGs)were screened and bioinformatics was used to cluster them.The screened genes were further analyzed with RT-qPCR to determine the time-dependent and dose-dependent relationships of the expression with THz exposure.Finally,sperm quality was evaluated morphologically using a microscope.Results Three doses of THz radiation exposure did not cause significant pathological damages to mouse testicular tissue.TNF-α expression was increased immediately after exposure at average power density of 115 mW/cm2(P<0.01),and the expression of IL-1β and TNF-α were both increased when the dose reached 318 mW/cm2(P<0.01).However,all the 3 factors returned to normal levels in 24 h after exposure.RNA-seq results showed that THz radiation exposure caused abnormal expression of 56 genes.Cluster analysis indicated that these DEGs were mainly enriched in immune and inflammatory responses,enzyme activity,sperm development and capacitation functions.Then for 5 selected key genes,Crisp1,Adam7,Ltf,Rnase9,and Bsph1,the expression of Crisp1 and Rnase9 was decreased immediately after exposure to 115 mW/cm2 THz radiation,the dose of 318 mW/cm2 resulted in obvious changes in the expression of the 5 genes(P<0.05),and their expression returned to normal levels in 24 h after exposure.Morphological observation displayed that exposure to all the 3 doses of THz had no influence on sperm quality.Conclusion THz radiation exposure causes temporary inflammatory response in testicular tissue and abnormal expression of sperm functions-related genes.However,these changes return to normal 24 h after exposure,and additionally,do not impair sperm quality.

Objective This study aimed to compare the current Essen rabies post-exposure immunization schedule(0-3-7-14-28)in China and the simple 4-dose schedule(0-3-7-14)newly recommended by the World Health Organization in terms of their safety,efficacy,and protection. Methods Mice were vaccinated according to different immunization schedules,and blood was collected for detection of rabies virus neutralizing antibodies(RVNAs)on days 14,21,28,35,and 120 after the first immunization.Additionally,different groups of mice were injected with lethal doses of the CVS-11 virus on day 0,subjected to different rabies immunization schedules,and assessed for morbidity and death status.In a clinical trial,185 rabies-exposed individuals were selected for post-exposure vaccination according to the Essen schedule,and blood was collected for RVNAs detection on days 28 and 42 after the first immunization. Results A statistically significant difference in RVNAs between mice in the Essen and 0-3-7-14 schedule groups was observed on the 35th day(P<0.05).The groups 0-3-7-14,0-3-7-21,and 0-3-7-28 showed no statistically significant difference(P>0.05)in RVNAs levels at any time point.The post-exposure immune protective test showed that the survival rate of mice in the control group was 20%,whereas that in the immunization groups was 40%.In the clinical trial,the RVNAs positive conversion rates on days 28(14 days after 4 doses)and 42(14 days after 5 doses)were both 100%,and no significant difference in RVNAs levels was observed(P>0.05). Conclusion The simple 4-dose schedule can produce sufficient RVNAs levels,with no significant effect of a delayed fourth vaccine dose(14-28 d)on the immunization potential.
