摘要:目的:分析本院住院城镇及农村患者的乙型肝炎病毒感染及免疫情况,推测不同区域发病及免疫状况,为免疫预防及临床提供参考。方法:收集我科2000年度,2004年度,2008年度住院患者的乙肝五项检测报告,按患者长期居住地分为农村组及城镇组,对比分析两组患者乙型肝炎病毒感染、具有免疫力及无免疫力年度变化情况及不同组别的差异。结果:同农村组相比,城镇组乙型肝炎病毒感染率、无免疫率低于农村组,免疫率高于农村组。年度对比乙型肝炎病毒感染率及免疫率呈上升趋势,无免疫率呈下降趋势。结论:近年来乙型病毒性肝炎发病有上升趋势,农村地区免疫普及率相对较低,仍为发病及预防免疫的重点区域,应给予足够重视。Abstract: Objective: To observe the disposition of infection and immunifaction on type B hepatitis in patients from hospital, suppose the disposition of infection and immunifaction in differently region, and provide information for immunifaction and clinical treatment. Methods: Reports of type B hepatitis from patients in hospital were collected, and were divided into town group and country group according to the habitation of patients. The difference of infection, immunifaction and no immunifaction were compared between two groups. Results: In comparison with the country group, the percentage of infection and no immunifaction was lower in town, and immunifaction was higher, attack rate of type B hepatitis had a tendency to increasing and no immunifaction was decreased by contrasting with annum. Conclusion: Recent years, attack rate of type B hepatitis has a tendency to increasing, and the popular rate of immunifaction is lower in country, so country is still the focal point of immunifaction and infection, and sufficient attention must be paid.
