目的 探讨CAl99在T2DM患者与健康人群中的差异及CAl99与糖化血红蛋白(HBAlc)的相关性。方法 收集2013年1月—9月T2DM患者382例,选择同期健康体检者90例作为对照组,分别检测血清CA199与HbA1c水平,根据HbA1c水平将T2DM患者分为血糖控制组(HbA1c<7.5%),控制不佳组(HbA1C≧7.5%),T2DM患者CA199水平与对照组比较,以体重指数、空腹血糖、HbA1c等为自变量,比较各变量对CA199的影响程度。结果 T2DM患者中CA199水平高于对照组,两者比较差异有统计学意义(t=3.45,P=0.005),血糖控制不佳组CA199阳性率(21.4%)高于血糖控制组(4%),差异有统计学意义(χ²=43.33,P=0.006),HBAlc控制组(4%)与健康体检者(0.9%)无显著差异(t=0.347,P=0.254,),CA199水平与HbA1c的相关系数最高(r=0.573,P=0.004)。结论 T2DM患者CA199水平和HbA1c存在相关性, 2型糖尿病患者CAl99升高与长期血糖控制不佳有关。

Objective To explore the differences in patients with T2DM and healthy people and to explore the correlation between CA199 and HbA1c in patients with T2DM. Methods 382 patients with T2DM and 90 healthy subjects for control group were collected from January to September in 2013.The level of CA199 and HbA1c were measured by chemiluminescence method and high performance liquid chromatography assay respectively. Accordingto the level of HbA1c,patients were divided in to blood glucose controlled group(HbA1c<7.5%) and blood glucose uncontrolled group (HbA1c≧7.5%).The level of CA199 were compared with control group. Sex, age, course of disease, body mass index, fasting blood glucose and HbA1c were included as independent variables for multiple stepwise regression analysis, to compare of influences of the variables on the CA199. Results The level of CA199 in T2DM patients was significantly higher than those of healthy subjects(t=3.45, P=0.005) and the positive rate of CA199 in blood glucose uncontrolled group(21.4%) was significantly higher than those of controlled group(4.0%)(χ²=43.33,P=0.006),there is no significant difference between in blood glucose controlled group(4.0%) and healthy people group(0.9%)(t=0.347,P=0.254).Among the many variables, the level of CA199 and HbA1c correlation coefficient was the highest (r=0.573, P=0.004. Conclusion There was a close correlation between CA199 level and HbA1c.There was a correlation between the positive level of CA199 and uncontrolled blood glucose.
