摘　　要：目的观察酸敏感离子通道亚基3(ASIC3,又名ACCN3)基因敲除ASIC3-/-小鼠、香草酸瞬时受体亚型I(TRPV1)基因敲除TRPV1-/-小鼠的生存曲线,为进一步繁殖使用该品系小鼠提供参考。方法选用105只基因敲除小鼠,其中ASIC3-/-鼠44只,TRPV1-/-鼠61只。观察正常喂养两种小鼠500 d以内的生存情况,并绘制生存曲线,进行生存分析。结果 ASIC3-/-小鼠与TRPV1-/-小鼠随着时间的延长,生存概率降低,经比较TRPV1-/-小鼠的生存概率优于ASIC3-/-小鼠的生存概率,两种小鼠的生存时间存在统计学差异,(P=0.004,P<0.01),两种小鼠中不同性别之间的生存曲线无显著学差异。结论 TRPV1-/-小鼠的生存概率优于ASIC3-/-小鼠的生存概率。而两种鼠不同性别之间的生存概率则基本相当。Objective To analyze the survival curves of ASIC3 -/-and TRPV1 -/-mice, and provide a reference for further breeding of these strains of mice.Methods Forty-four ASIC3 -/-mice and sixty-one TRPV1 -/-mice were included in this study.The survival of the mice was observed in normal feeding for 500 days, survival curves were drawn, and their survival was analyzed.Results With the passing of time, the survival probability was decreased in ASIC3 -/-mice and TRPV1 -/-mice.The survival probability of TRPV1 -/-mice was significantly better than that of ASIC3 -/-mice （P =0.004, P 〈0.01）.No significant difference was observed between the males and females of the same strain. Conclusions The survival probability of TRPV1 -/-mice is better than that of ASIC3 -/-mice.There is no significant gender difference in the two strains of mice.
