目的 探讨DPP-4抑制剂西格列汀对成人隐匿性自身免疫性糖尿病(LADA)早期患者胰岛β细胞功能的影响。方法 把14例新诊断为LADA患者随机分为两组,胰岛素治疗100 mg/d西格列汀(A组,n=7)或无西格列汀(B组,n=7)共治疗9个月。结果 9个月后两组之间的血糖和糖化血红蛋白水平无差异。9个月后A组空腹C肽(FCP),餐后C肽(CP),和ΔCP(ΔCP=2 h CP-FCP)水平与基线相比无明显差别(P＞0.05),B组FCP,2 h的CP和ΔCP进行比较基线显著下降(P<0.05)。A组2 h CP水平明显高于B组(P<0.05)。结论 胰岛素与西格列汀联用较单用胰岛素治疗成人隐匿性自身免疫糖尿病早期患者似乎能更好保护胰岛β细胞功能,西格列汀或可延长LADA非胰岛素依赖期的时间。

Objective The Objective of the study was to investigate the effects of the DPP-4 inhibitor on β-cell function in patients with recent-onset latent autoimmune diabetes in adults LADA. Methods Fourteen recently diagnosed LADA patients were randomized into two groups, A and B, to receive insulin therapy with 100 mg/d sitagliptin (group A, n=7) or without sitagliptin (group B, n=7) for 9 months. Results There were no differences in the clinical baseline data between the two groups. During the 9 months of follow-up, there were no significant differences in glucose and glycosylated hemoglobin levels between the two groups. At 9 months, there were not different in group A including fasting C-peptide (FCP), 2-hour postprandial C-peptide (CP), and ΔCP(ΔCP=2 h CP-FCP) levels (P>0.05). Compared with baseline, whereas in group B the levels of FCP, 2-hour CP and ΔCP were significantly decreased compared with baseline (P<0.05). Levels of 2-hour CP were higher in group A, it was higher than group B at 9 months (P<0.05). Conclusion LADA patients treated with sitagliptin and insulin was more likely maintain β-cell function by comparison with insulin alone. Sitagliptin administration in patients with LADA might prolong the insulin-free period.

目的 探讨绝经期后女性血清铁蛋白水平与代谢综合征之间的关系。方法 收集218例确诊为MS的绝经期后女性患者为试验组,对照组为经我院检查健康绝经期后的女性300例,分别测FBG、TC、TG、LDL-C、HDL-C、HbA1C、INS、SF;计算体重指数(BMI)以及测量腰围;测血压;用HOMA稳态模型来评价胰岛素抵抗指数(HOMA-IR)。结果 MS组较非MS组的铁蛋白(SF)值高(P<0.01),SF四分位各组之间比较,FBG、TG、HDL-C,BMI,腰围,收缩压、舒张压有差异(P<0.05或P<0.01),四组间年龄、TC、LDL-C无差异。与SF呈正相关的参数有腰围(P<0.01),舒张压(P<0.01),空腹血糖(P<0.01),胰岛素抵抗指数(P<0.01),负相关的参数为HDL-C(P<0.01)。结论 绝经期后女性的SF水平与MS呈显著相关,其中腰围、舒张压、空腹血糖、HDL-C、胰岛素抵抗指数与血清铁蛋白之间存在较大关联性。

Objective To study the relationship of serum ferritin level with metabolic syndrome in postmenopausal women. Methods 218 postmenopausal women with metabolic syndrome and 300 healthy postmenopausal women were included in this investigation, to detect FBG, TC, TG, LDL- C, HDL-C, HbA1C, INS, SF, calculated body mass index (BMI) and to measure waist circumference, blood pressure; Using HOMA steady-state model to evaluate indexes of insulin resistance (HOMA IR). Results Serum ferritin level was significantly higher in MS group than in the non-MS group(P<0.01). Serum ferritin quarterback was compared between each group, there were differences in FBG, TG, HDL-C,BMI, waist circumference,SBP, DBP(P<0.05 or P<0.01). There were no differences in age, TC, LDL-C. Serum ferritin level was significantly positive correlated with waist circumference (P<0.01), DBP(P<0.01), FBG(P<0.01), insulin resistance index (P<0.01), and negative correlation with HDL-C(P<0.01). Conclusion Serum ferritin level is significantly associated with metabolic syndrome in postmenopausal women. Waist circumference, DBP, FBG, HDL -C, insulin resistance index are closely associated with the serum ferritin.

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.
