Tae formation,development and rupture of intracranial aneurysms result from the interaction of genetic and environmental factors.The genetic mode may be nonclassical Mendelian inheritance for most patients with intracranial aneurysms.Studies have shown that COL3A1 and COLI A2 genes of the coded main extracellular matrix proteins in the arterial walls are closely associated with intracranial aneurysms.

Objective To investigate the correlation between executive function(EF) and characteristic of symptom in children with Tourette′s syndrome(TS).Methods EF were measured with Wisconsin Card Sorting Test(WCST) in 53 patients with TS,and symptom characteristics were evaluated with Achenbach Child Behavior Checklist(CBCL) and Yale Global Tic Severity Scale(YGTSS).Results Compared with healthy control,TS had poor executive performances significantly in WCST(all P

Increased recognition of human parvovirus B19,as a significant human pathogen has resulted in intensive researches to understand the pathogenesis of B19 infection,to elucidate the nature of Th1-mediated cellular immune response,to improve diagnostic strategy that is deployed to detect B19 infection and blood-product contamination,and to lay a foundation that should contribute to the development of an effective vaccine to prevent B19 infection.In this review,the biologic characteristics and the pathogenesis of human parvovirus B19,and B19-related manifestations as well as laboratory diagnostic methods for B19 infection were comprehensively discussed.

Aim To investigate the age-related changes of TrkB mRNA in hippocampal formation of aged rats,and the effects of ginsenosides(GS),and provide reliable experimental evidence for anti-aging.Methods 24 Wistar female rats were randomly divided into 3 groups: Young,aged and GS group(fed with GS from 17 to 27 months).In situ hybridization(ISH) method was applied into qualifying and quantitating the TrkB mRNA expression in hippocampal formation.Results TrkB mRNA expression in aged CA3,CA1 and dentate gyrus decreased by 24.2%,13.4% and 50.6%(P

Objective:To analyze the relationship between hepatitis B virus(HBV)gene mutation at 1896 in precore region with genotype and replication of HBV and the liver function of patients.Methods:HBV precore 1896 site mutation,the genotype of HBV and serum content of HBV DNA were determined by PCR in 60 patients positive of HBV DNA.Chemiluminescence miacropaticle immunoassay(CMIA)was used for detection of serum HBeAg and HBeAb.Liver function parameters were ob- tained by routine biochemistry method.Results:The alanine aminotransferase(ALT)level in HBV with 1896 site mutation was significantly higher than that in the wildtype virus.Site mutation at 1896 had no correlation with HBeAg,HBV genotype and HBV DNA content.HBV DNA content in patient with genotype C was significantly higher than that with genotype B(P
