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 explore the mechanism of protection role of ambroxol against acute lung injury (ALI)by studying the change of cytokine mRNA expression during the course of ALI.Method The study was composed of experiments both in vivo and in vitro. (1)Experiments in vivo were as follows.Twenty-four sprague-Dawley rats were randomly divide into 3 groups,namely,control group(n=8),acute lung injury group(LPS group,n=8)and ambroxol group(LPS+A group,n=8).The rat model of acute lung injury was induced by intraperitoneal injection of 10 mmol/L lipoopolysaccharide(LPS).The pathological alteration of lung tissue and arterial partial pressure of oxygen(PaO2)were observed.Expressions of TNF-α,IL-10 and IL-24 mRNA were determined by using RT-PCR assay. (2)Experiments in vitro were the followings.Alveolar macrophage cells were collected and divided into 3 groups as above mentioned.Cells were treated with normal saline,with LPS,and with LPS plus ambroxolin dose of 180 μmol/L at 0,6,12 and 24 hours after exposure of LPS,respectively,in 3 groups as above stated.The expressions of TNF-α,IL-10 and IL-24 mRNA were also determine by using RT-PCR.Results The pathological changes of could be parially ameliorated by giving ambroxol.Massive hemorrhage along with vascular edema and infiltration occurred in the lungs of ALT rats.The pathological alterations in ALI rats treated with ambroxol were less severe.The expressions of TNF-α,IL-10 and IL-24 mRNA were dramatically increased in ALI rats,and were partially attenuated after treatment of ambroxol.Macrophages oxposed to LPS for 6 hours showed dramatical increase in expressions of TNF-α,IL-10 and IL-24mRNA those remained at high levels afterwards.The expressions of TNF-α,IL-10 and IL-24 mRNA in macrophages after exposure to both LPS and ambroxol were increased less than those exposed to LPS alone.Conclusions Ambroxol can partially ameliorate the expressions of TNF-α,IL-10 and IL-24 mRNA in alveolar macrophage induced by LPS.
