摘  要:目的:了解云南地区乙型肝炎病毒基因型分布特征,探讨其与慢性HBV感染者的性别和年龄、不同临床疾病谱、病毒复制水平的关系.方法:选择云南地区慢性HBV感染者117例其中慢性无症状乙型肝炎表面抗原携带者(ASC)26例、慢性乙型肝炎(CHB)55例(轻度21例、中度24例、重度10例)、慢性重型肝炎(CLF)18例、乙肝后肝硬化(LC)11例及原发性肝细胞肝癌(HCC)7例,采用反向杂交技术(RDB)检测HBV基因型,并对与其性别年龄、临床分型和病毒复制水平的关系进行分析.结果:云南地区HBV基因型以B型和C型为主,分别为41.0%(48/117)和54.7%(64/117),并以C型为最多(χ2=4.38,P=0.036);D型1例(0.86%),B、C混合型2例(1.71%),A、C混合型2例(1.71%).B基因型在轻度慢乙肝组所占的比例显著高于中、重度慢乙肝组(χ2=8.27、11.98,P=0.004、0.001)、ASC组(χ2=5.46,P=0.02)、CLF组(χ2=4.13,P=0.042)和LC/HCC组(χ2=11.3,P=0.001).C基因型在LC/HCC组和重度慢乙肝组所占的比例均显著高于轻度慢乙肝组(χ2=11.3,P=0.001;χ2=8.78,P=0.003),与其他各临床型组间的比较则无显著性差异(P>0.05).C基因型在HBVDNA(+)组和HBeAg(-)组r所占的比例均分别显著高于HBVDNA(-)组(χ2=6.63,P=0.01)和HBeAg(+)组(χ2=7.12,P=0.008).B基因型在HBVDNA低水平复制组中所占的比例显著高于高水平复制组(χ2=4.12,P=0.042).C基因型在HBVDNA高水平复制组中所占的比例显著高于B基因型(χ2=5.13,P<0.05).C基因型在年龄≥30岁组中所占的比例(63.3%)高于年龄<30岁组(45.6%)(χ2=3.7,P=0.05).HBV基因型在性别间的分布无统计学差异(P>0.05)结论:云南地区存在HBV的B、C、D、B+C和A+C基因型,以B型和C型为主要基因型,并以C型为最多.B基因型在轻度慢乙肝的比例显著高于其他各临床型HBV感染者,并且与HBV的低水平复制和低年龄有关.C基因型主要分布于重度慢乙肝和LC/HCC、HBVDNA高水平复制、年龄≥30岁的患者中.提示C基因型与慢乙肝重度AIM: To investigate the distribution of hepatitis B virus (HBV) genotypes in Yunnan province, China, and to explore the significance and the relationship of the HBV genotype with gender and age, clinical patterns of chronic HBV infection, and HBV replication. METHODS: Serum samples from 117 patients with chronic hepatitis B virus infection from Yunnan province, consisting of 26 chronic as- ymptomatic HBV carriers (ASC), 55 chronic hepatitis B (CHB) (mild 21, moderate 24 and severe 10), 18 chronic liver failure (CLF), 11 liver cirrhosis (LC) and 7 hepatocellular carcinoma (HCC), were analyzed by Reverse dot blot (RDB) for HBV genotyping. The relationships of HBV genotype with gender and age, clinical patterns, and serological data of the patients were analyzed. RESULTS: Genotype A, B, C and D were determined; 41.0% (48/117) were genotype B, 54.7% (64/117) genotype C, 0.86% (1/117) genotype D, 1.71% (2/117) genotype B+C and 1.71% (2/117) genotype A+C. Genotype B and C are predominant in this region of China. There was a statistically significant difference in the distribution of genotype B and C (2 = 4.38, P = 0.036). Genotype C was the dominant genotype and was prevalent in all patient categories. The ratio of genotype B in the mild CHB groups was significant higher than that in the moderate and severe groups (χ^2 = 8.27, P = 0.004; χ^2 = 11.98, P = 0.001, respectively), the ASC group (χ^2 = 5.46, P = 0.02), the CLF group (χ^2= 4.13, P = 0.042) and the LC/HCC group (χ^2= 11.3, P = 0.001). The ratios of genotype C in the LC/HCC group and in severe CHB groups were significant higher than that in the mild CHB groups (χ^2= 11.3, P = 0.001; χ^2 = 8.78, P = 0.003, respectively). The ratios of genotype C in the HBV DNA (+) and HBeAg (-) groups were higher than that in the HBV DNA (-) (χ^2 = 6.63, P = 0.01) and HBeAg (+) groups (χ^2 = 7.12, P = 0.008). The ratio of genotype B in the lowest-level gro
