摘要
目的:观察上海地区慢性丙型肝炎(慢丙肝)患者的丙肝病毒(HCV)基因型分布情况。方法:提取血清HCV RNA,套式PCR扩增方法扩增目的片段,纯化后直接测序。结果:71例血清标本检测示,1b型占87.32%(62/71),2 a型占12.68%(9/71),共有22个突变。1b型的突变率为33.87%(21/62),2 a型的突变率为11.11%(1/9)。两种基因型突变率比较,具统计学差异(P<0.05)。结论:该研究中HCV基因型为1b和2 a两型,1b型占多数,1b型的突变率高于2 a型。
Objective: To study the distribution of HCV Genetype in Shanghai. Methods: HCV RNA was extracted and amplified by nested PCR, then purified and sequenced directly. Results: 1b genetyep aeounted for 87. 32% (62/71), 2a genetype for 12.68% (9/71) . There were 22 mutation in all samples 33.87% in lb genetype and 11.11% in 2a genetype. Conclusion: The study shows that there are lb and 2a genetypes, and lb genetype is in the majority. The mutation rate of 1 b genetype is more than 2a genetype ( P 〈 0. 05 ) .
