| 目的 了解江苏省2009年3岁以上自然人群新甲型H1N1流感抗体水平及流行趋势。方法 利用微量半加敏血凝抑制(HI)方法检测江苏省不同时间(2008年11月和2009年7、8、11月)人群新甲型H1N1流感抗体，比较不同时间、人群及地区的新甲型H1N1流感保护性抗体阳性率和抗体几何平均滴度(GMTs)。结果 在新甲型H1N1流感输入江苏地区后第一个流行季节内，2009年7、8、11月人群HI保护性抗体阳性率依次为3.46%、7.59%和16.94%，表现出随时间推移而呈总体增长趋势(P=0.000)，不同时间点的性别间保护性抗体阳性率的差异无统计学意义(P>0.05)；除2009年11月外，不同性别间的抗体GMT差异均无统计学意义。同一时间点不同年龄组间、同一年龄组的不同时间点间，HI保护性抗体阳性率、抗体GMT水平比较的差异均有统计学意义(P<0.05)。HI保护性抗体阳性率和抗体GMT存在地区差异(P<0.05)。结论 在2009年8月后江苏地区12～17岁人群成为新甲型H1N1流感暴发的主要人群，至2009年11月该人群总体新甲型H1N1流感保护性抗体阳性率仍较低，该病在全省的流行仍将持续一段时间。 |

| Objective To understand the antibody levels against pandemic influenza A (H1N1) virus (2009 H1N1)among aged≥3 years population in 2009,from Jiangsu province,and to describe the distribution of 2009 H1N1.Methods Serum specimens were collected from natural populations at four different periods in Jiangsu,and tested with hemagglutination-inhibition (HI) assays.Rates of protective antibody against 2009 H1N1 and Geometric mean titers (GMTs) were estimated.Results The rates of protective antibody against 2009 H1N1 rose with the progress of epidemics in Jiangsu,which were 3.46%,7.59%,16.94%,respectively in July,August and November,2009.There were no significant differences on the rates of protective antibody between males and females at foot different cross-sectional periods (P>0.05),and no significant differences on GMTs were observed at different periods except for November 2009.Significant differences on rates of protective antibody and GMTs among various age groups were observed at four different periods (P<0.05),and similar results were observed among different periods in various age groups (P<0.05).There were significant differences on rates of protective antibo勿and GMTs among different areas (P<0.05).Conclusion The 2009 H1N1 strain had been widely spread out in Jiangsu province since July 2009.People aged 12-17 years became the major victims after August.As of November 2009,the rate of protective antibody against 2009 H1N1 was still low,predicting that the epidemic might continue to exist for a certain period of time. |
