Research on Hepatitis B virus Genotypes and Subgenotypes among Bai Nationality in Dali, Yunnan Province / 中国病毒学·英文版

To investigate the distribution of hepatitis B virus (HBV) genotypes and subgenotypes among the Bai nationality in Dali, a total of 100 serum samples from patients with chronic HBV-infection were collected for the detection of HBV genotypes and subgenotypes by genotype-specific primers and restriction fragment length polymorphism (RLFP), respectively. Among the 100 samples, the proportions of genotype B, C and mixed genotype (B+C) were 41%, 25% and 34%, respectively. All the genotype B strains belonged to subgenotype Ba. In genotype C, 84% were Subgenotype Cs and 12% were subgenotype Ce. The distribution of genotypes B, C and B+C showed no significant difference between male and female patients (P=0.182) and among the age groups of patients (P=0.812). The rates of HBeAg/HBeAg positivity were no significantly different among genotypes B, genotype C and mixed genotype (B+C) (P=0.077/P=0.663). In Dali, genotypes B, B+C and C existed among Bai nationality with chronic HBV-infection, and genotype B was the major genotype. Subgenotypes Ba and Cs were the predominant strains in patients with HBV genotype B/C infection. The most prominent characteristic was the higher prevalent rate of mixed genotype (B+C) in patients.

INVESTIGATION OF FINGER RIDGE COUNT AND T TRIANGLE OF DALI BAI NATIONALITY IN CHINA / 解剖学报

of little finger.And the mean value of each finger had a significant difference between males and females(P0.05).Along with the increasing deviation value of FRC between corresponding fingers,the variety trend of the frequency was gradually reducing,and an overwhelming majority(88.2%) of the value was less than or equal to 3.The frequency distribution of TFRC was close to a normal distribution.The mean value of atd angle was 40.27?4.34 and that of tPD(12.46?4.66)%.Both of atd angle and tPD had a significant difference between males and females(P0.05).The frequency of tPD under 15% was 72.5%,and none was over 30%.Conclusion The distribution of FRC and triangle in corresponding fingers of Bai nationality is symmetric and it shares some common features with that of other ethnic groups with its own characteristics.
