杨梅小环腹瘿蜂Leptopilina myrica是一种于浙江省诱捕得到，能高效寄生果蝇幼虫的内寄生蜂，目前国内外对该物种的报道较少。本研究运用形态成像，血细胞计数和实时荧光定量PCR等方法对杨梅小环腹瘿蜂的生物学特性及其寄生对寄主免疫反应的影响进行研究。结果表明，杨梅小环腹瘿蜂在寄主体内完成卵期、幼虫期和蛹期三个阶段。在实验室条件下，杨梅小环腹瘿蜂能高效寄生包括斑翅果蝇在内的多种果蝇属害虫；其对黑腹果蝇Drosophila melanogaster的寄生率和出蜂率相对较高，分别为87.3%和70.6%。此外，杨梅小环腹瘿蜂寄生会引起黑腹果蝇寄主强烈的免疫反应：被寄生后的寄主血细胞数量明显增加，并在寄生48h后诱导产生大量的薄层细胞参与包囊反应；寄生后的寄主体内Imd、Toll以及PO等免疫通路中主要基因的转录水平显著上升。面对黑腹果蝇寄主的免疫反应，杨梅小环腹瘿蜂通过将卵粘附于肠道等寄主组织的方式逃避寄主免疫，从而成功寄生。本研究揭示了杨梅小环腹瘿蜂成功寄生果蝇类害虫的机制，为害虫生物防治提供重要的知识储备。

目的探究糖尿病酮症酸中毒(diabetic ketoacidosis,DKA)患者治疗中选择不同治疗方式(胰岛素泵皮下输注、胰岛素静脉滴注)对血糖水平、症状缓解时间的影响。方法回顾性选取泉州市第一医院于2023年1月—2024年1月收治的108例DKA患者临床资料,按不同治疗方式分为两组,观察组(n=54)行胰岛素泵皮下输注、对照组(n=54)行胰岛素静脉滴注,对比两组血糖水平、症状缓解时间、临床疗效。结果治疗15 d后,观察组血糖水平低于对照组,差异有统计学意义(P<0.05)。观察组尿酮体转阴、血酮体转阴和血糖达标时间均短于对照组,差异有统计学意义(P均<0.05);观察组临床疗效(96.30%)高于对照组(85.19%),差异有统计学意义(χ^(2)=3.967,P<0.05)。结论DKA患者治疗中胰岛素泵皮下注射控糖效果优于胰岛素泵静脉滴注,症状缓解时间更短,疗效显著。
