摘要 目的探讨1~6岁厌食症患儿血清瘦素(LP)、NPY(NPY)和肿瘤坏死因子-α(TNF-α)水平的变化及其相关性,分析其在厌食症发病过程中的作用。方法用放射免疫分析法检测47例厌食症患儿(厌食症组)和35例正常小儿(正常对照组)血清LP、NPY和TNF-α水平,测量受试者身高和体重,计算体重指数(BMI)[BMI=体重(kg)/身高(m2)]。结果厌食症组患儿体内LP、NPY、TNF-α和BMI明显低于正常对照组,2组比较差异均有统计学意义(P<0.05);正常对照组LP与BMI,NPY和TNF-α呈正相关(r分别为0.009和0.431,P<0.05),厌食症组4项指标无明显相关性(P>0.05)。结论LP、PY和TNF-α均在厌食症发病中起着重要作用,与厌食症发病机制有关,低LP,NPY水平可能是机体的一种防御反应,起到保护作用,TNF-α可能是造成厌食症患儿食欲低下的调控因子。
