方法：选取2014-06/2015-04于本院进行治疗的67例白内障患者为观察组，并从于本院体检者中选取67例同龄健康人为对照组，然后将两组的泪液及血清白介素、微量元素进行检测及比较，并比较不同发病时间及分期白内障患者的上述检测指标，并采用logistic法分析泪液及血清检测指标与白内障的关系。

结果：观察组的泪液及血清白介素均高于对照组，而微量元素则低于对照组，且不同疾病分期白内障患者的检测指标也存在明显差异(均P<0.05)，而不同发病时间患者间则无明显差异(均P>0.05)，经logistic法分析泪液及血清检测指标与白内障有密切的关系。

结论：白内障患者的泪液及血清白介素及微量元素呈现异常的状态，并且不同疾病分期患者的差异也较为突出，检测指标与疾病的关系密切。

METHODS:Sixty-seven patients with cataract in our hospital from June 2014 to April 2015 were selected as observation group,67 healthy persons at the same ages who were for physical examination in our hospital were selected as control group. Then interleukins and trace elements in tears and serum of the two groups were detected and compared. Then those detected indexes of observation group with different onset time and disease stages were compared,and the relation of detected indexes in tears and serim with cataract were analyzed by logistic analysis.

RESULTS:The lever of interleukins in tears and serum of observation group were all higher than those of control group,while lever of the trace elements were all lower than those of control group; and the detected indexes of patients with different stages of cataract had obvious differences(all P<0.05). But the detected results of patients with different onset time had no obvious differences(all P>0.05).The relation of the detected indexes in tears and serum with cataract were close by the logistic analysis.

CONCLUSION:The interleukins and trace elements in tears and serum of patients with cataract show abnormal state,and the differences between the indexes of patients with different disease stages are obvious. The relation between the detected indexes and disease are close.
