[摘要] 目的 探讨重症患者疾病严重程度与维生素D水平的相关性。 方法 方便选取2015年12月—2016年12月该院收治的50例重症患者分成观察1组(n=33)与观察2组(n=17)，进行一般指标对比，并与同期在该院门诊进行体检的50名健康人士的25-羟维生素D水平进行对比。 结果 两组患者的性别占比、血小板计数、CRP水平、血清钙水平及血清磷水平差异无统计学意义(P>0.05)，而合并器官功能障碍占比、病死率、APACHE Ⅱ平均评分、25-羟维生素D水平、白细胞计数、乳酸均差异有统计学意义(P<0.05)；重症患者的25-羟维生素D水平明显低于健康人士；APACHE Ⅱ评分与25-羟维生素D水平呈负相关。结论 重症患者严重缺乏维生素D，疾病严重程度越重，维生素D水平越低。

    [Abstract] Objective This paper tries to investigate the correlation between disease severity and vitamin D levels in critically ill patients. Methods 50 critically ill patients admitted to this hospital from December 2015 to December 2016 were divided conveniently into observation group 1(n=33) and observation group 2 (n=17). The general index of the 25-hydroxy vitamin D levels of 50 healthy people on physical examination of the same period in this hospital was compared. Results There was no significant difference in gender share ......
