Abstract: |
目的<\b> 了解中国乙型肝炎病毒(HBV)慢性感染者中HBV基因型的分布情况.方法<\b> 收集北京、清远、深圳、石家庄、汉川、南京、长春、济南、聊城、宁波和温州市共1214份HBV DNA阳性的慢性HBV感染者血清样本,用型特异性引物聚合酶链反应法(PCR)进行基因型测定,并对其中部分样本以PCR产物直接测序验证.结果<\b> 在1214份血清中,检测到A基因型9例,占0.7%;B基因型345例,占28.4%;C基因型709例,占58.4%;B、C混合基因型(B+C)151例,占12.4%.未检测到其他基因型.北方地区(长春、北京、石家庄市等)慢性HBV感染者中,C基因型比例较高,分别为58.2%、67.5%和63.6%,山东省聊城和济南市的C基因型比例分别高达90.2%和87.9%.随地理位置南移,B基因型比例逐渐增加,广东省清远和深圳市的B基因型比例分别为71.4%和63.6%.结论<\b> HBV基因型分布有明显地区差异.在中国慢性HBV感染者中,HBV C和B基因型为主要流行株.北方地区以C基因型为优势株,而南方地区则B基因型较为多见. |

Objective<\b> To investigate the distributionof hepatitis B virus(HBV)genotypes in patients with chronic HBV infection among 11 cities of China.Methods<\b> A total of 1214 serum samples from patients with chronic HBV infection were collected in 1 1 cities of China,including Be巧ing,Qingyuan,Shenzhen,Sh巧iazhuang,Hanchuan,Nanjing,Changchun,Liaocheng,Jinan,Ningbo and Wenzhou.GenotypeS of the 1214 HBV strains were identified by PCR method with type specific primers.Parts of the results were confirmed by direct sequencing analysis of PCR products.Results<\b> Among the 1214 patients with chronic HBV infection,0.7%(9/1214)were genotype A,28.4%(345/1214)genotype B,58.4%(709/ 1214)genotype C,and 12.4%(151/1214)genotype B and genotype C mixed infection.Noother genotypes were found.Genotype C was predominant in the northern part of China,such as Changchun,Beijing,Shijiazhuang,while genotype B was more commonly seen in south of China.71.4%(20/28)for patients from Qingyuan and 63.6%(70/110)from shenzhen were infected with genotype B.conclusion HBV genotypes had distinct geographic distribution.Genotype B and C the predominant strains in patients with chronic HBV infection in China.Genotype C was predominantly identified in the northern part of China versus genotype B the south. |
