摘　　要：目的分析慢性乙型肝炎患者幽门螺杆菌(Hp)感染状况及肝组织螺杆菌属特异性16Sr RNA基因特点。方法纳入维吾尔族CHB患者60例和健康维吾尔族体检者80例,采用14C-尿素呼气试验检测H pylori阳性感染,常规进行肝穿刺,采用PCR法检测肝组织螺杆菌16Sr RNA基因水平。结果慢性乙型肝炎每分钟衰变数(14C-UBT)阳性率为85.00%,显著高于对照组[60.24%,P<0.01];在所谓的60例慢性乙型肝炎患者中,经肝组织学检查,发现慢性乙型肝炎46例,肝硬化14例;在46例CHB和14例肝硬化患者肝组织DNA进行16 Sr RNA基因检测,结果 40例(86.96%)CHB和13例(92.86%)肝硬化患者16 s RNA阳性,两组差异无统计学意义(x2=0.363,P>0.05);轻度、中度与重度CHB患者肝组织16 s RNA检出率亦无统计学差异(x2=1.348,P=0.510)。结论慢性乙型肝炎患者幽门螺杆菌感染率较高,但肝组织螺杆菌属特异性16Sr RNA检出率与乙型肝炎患者肝组织炎症或纤维化程度未显示出显著性关联。Objective To analyze the Helicobacter pylori （Hp） infection status in Uygur patients with chronic hepatitis B in Xinjiang and helicobacter 16SrRNA gene in liver biopsy tissues. Methods 60 patients with hepatitis 13 and 80 healthy persons were recruited in this study. 14C-urea breathing test was used to detected Hp infection,and helicobacter 16SrRNA gene in liver biopsy tissues were detected by using real-time PCR and pathological examination was applied to determine histological activity index. Results The ^14C-UBT positive rate was 85.00% in patients with hepatitis B,significantly higher than 60.24% in the controls （P〈0.01）; 14 out of 60 patients with hepatitis B were diagnosed with liver cirrhosis by histopathological examination; the positive rate of helicobacter 16SrRNA in liver tissues from patients with CHB were 86.96% ,without significant difference as compared to 92.86% from patients with liver cirrhosis （x2=0.363,P〉0.05）;there were no significantly statistical differences as respect to the positive rates of helicobacter 16SrRNA in liver tissues among 21,16 and 9 patients with hepatitis B of mild,moderate and severe degree （x2=1.348,P=0.510）. Conclusion The infection of Hp in patients with CHB is common,but there is no significant evidence showing correlation of the specificity 16SrRNA of Hp to pathological grading and staging in liver tissues.
