Chinese Journal of Postgraduates of Medicine 2017;40(2):125-128
Objective To compare the clinical characteristics of pregnant women with gestational diabetes mellitus (GDM) and normal gestational glucose metabolism at the 25th weeks of pregnant. Methods Sixty-eighty patients with GDM (GDM group) and 68 patients with normal blood glucose(control group) were enrolled in this study. During 25 weeks of pregnancy, oral glucose tolerance test (OGTT), blood pressure, fasting insulin, glycosylated hemoglobin, uric acid, triglyceride, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol were measured and body mass index (BMI), homeostasis model of assessment for insulin resistence index (HOMA-IR), insulin sensitivity index (ISI) were computed. The results were compared between two groups. Results The age in GDM group was significantly higher than that in control group: (31.38 ± 0.54) years vs. (29.50 ± 0.56) years, P<0.05. The systolic pressure in two groups had no significant difference (P>0.05), but diastolic blood pressure in GDM group was significantly higher than that in control group:(73.2 ± 0.8) mmHg vs. (70.9 ± 0.8) mmHg, 1 mmHg=0.133 kPa, P<0.05. The body weight and BMI in GDM group were significantly higher than that in control group:(65.67 ± 1.76) kg vs. (57.76 ± 1.11) kg, (24.77 ± 0.61) kg/m2 vs. (22.11 ± 0.42) kg/m2, P<0.01. The levels of glycosylated hemoglobin, fasting insulin and HOMA- IR in GDM group were significantly higher than those in control group (5.546 ± 0.746)% vs. (5.085 ± 0.034)% , (17.870 ± 1.015) mU/L vs. (14.400 ± 0.634) mU/L, 4.192 ± 0.271 vs. 2.645 ± 0.128, but the level of ISI in GDM group was significantly lower than that in control group:0.014 ± 0.001 vs. 0.020 ± 0.001, and there were significantly differences (P<0.01). The levels of uric acid, triglyceride, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol in two groups had no significant differences (P>0.05). Conclusions Compared to those with normal blood glucose, the patients with GDM have the characteristics of higher age, higher body weight, higher BMI, higher diastolic blood pressure , higher level of insulin, insulin resistance and decreased insulin sensitivity.

Objective To investigate the long-term efficacy of autologous stem cell transplantation for systemic lupus erythematosus (SLE). Methods Long-term follow up of 48 SLE patients with autologous stem cell transplantation were studied. All patients were followed up for 10 years. Among the patients, 24 cases were treated with purified CD34+ cells transplantation and 24 cases were treated with non-CD34+ cell transplantation. Comparison between groups was performed by x2 test. Results Among 5 dead patients, 4 died of transplantation related complications including 3 cases treated with CD34+ transplantion. The survival rate of those patients with more than 10 years duration of lupus was 90%(43/48). Among 43 patients, 7 had disease flare, 6 were treated with non-CD34+ cell transplantation. Eight patients went to college, 26 returned to normal life and 4 of them had children. Conclusion The long-term effect of SLE treated with autologous hematopoietic stem cell transplantation and anti-thymocyte globulin (ATG) is good. The recurrence of CD34+ transplant patients is lower than those treated with non-CD34+ transplantation. The quality of life in SLE patients treated with transplantation is better than those treated with conventional therapy.
