Objectives To investigate gestational multiple metabolic abnormalities aggregation and diagnostic criteria for gestational metabolic syndrome(GMS),and to analyze the risk factors of GMS.Methods A cohort study recruiting 309 pregnant women with preeclampsia,627 pregnant women with gestational diabetes mellitus(GDM)and 1245 normal pregnant women was performed from January 2008 to December 2011 in Guangdong Women and Children's Hospital.Information regarding age,gestational weeks,basic blood pressure,admission blood pressure,height and body mass index(BMI)before pregnancy was recorded.Biochemical indicators including fasting plasma glucose(FPG),fasting insulin (FINS),total cholesterol(TC),triglyceride(TG),high density lipoprotein(HDL-C),low density lipoprotein(LDL-C),free fatty acids(FFA)were tested.GMS was diagnosed with three or all of the following conditions:(1)overweight and/or obesity before pregnancy(BMI ≥ 25 kg/m2);(2)hypertension with blood pressure ≥ 140/90 mm Hg(1 mm Hg =0.133 kPa);(3)hyperglycemia:diagnosed as GDM;(4)dyslipidemia with TG≥3.23 mmol/L The incidence of GMS of the three groups were calculated and the risk factors were analyzed.Results(1)The age,gestational weeks,basic blood pressure,admission blood pressure,BMI before pregnancy of women with preeclampsia and women with GDM were significantly different compared to normal women,respectively(P < 0.01).(2)Biochemical indicators of women with preeclampsia were as following:FPG(4.6 ± 1.0)mmol/L,FINS(10.1 ± 5.6)mU/L,TC(6.3 ±1.6)mmol/L,TG(3.9 ± 1.8)mmol/L,HDL-C(1.4 ±0.4)mmol/L,LDL-C(3.0 ± 1.0)mmol/L,FFA (0.8 ±0.4)mmol/L.And those in women with GDM were:FPG(4.7 ± 0.9)mmoL/L,FINS(10.2 ± 5.8)mU/L,TC(5.7 ± 1.3)mmol/L,TG(3.2 ± 1.1)mmol/L,HDL-C(1.4 ± 0.4)mmol/L,LDL-C (2.7 ± 0.9)mmol/L,FFA(0.6 ± 0.3)mmol/L In normal pregnant women they were:FPG(4.3 ±0.5)mmol/L,FINS(9.0±4.4)mU/L,TC(5.7 ±1.1)mmol/L,TG(2.8 ±1.1)mmol/L,HDL-C (1.5 ± 0.4)mmol/L,LDL-C(2.9 ± 0.8)mmol/L,FFA(0.6 ± 0.2)mmol/L Statistic differences were found in preeclampsia and GDM women compared to normal women respectively(P < 0.01).(3)The prevalence of GMS in preeclampsia group and in GDM group was 26.2%(81/309)and 13.6%(85/627),statistically different from that of the control group(0)(P <0.01).(4)Compared to normal women,women with preeclampsia had higher risk of developing GMS(OR =1.62,95 % CI 1.31-2.00,P < 0.01).The risk factors were BMI(OR =1.29,95% CI 1.13-1.47)and TG(OR =2.49,95% CI 1.87-3.31).Also,women with GDM had higher risk of developing GMS than normal women(OR =1.27,95% CI 1.09-1.49,P < 0.01),and the risk factors were BMI(OR =1.13,95 % CI 1.04-1.23)and TG(OR =1.16,95 % CI 1.02-1.33).TG was the independent risk factor in both preeclampsia women and GDM women(P < 0.01,P < 0.05).HDL-C seemed to have less importance in identifying GMS(P > 0.05).Conclusions According to the GMS diagnostic criteria used in this study,some preeclampsia patients and some GDM women had aggregation of multiple metabolic abnormalities including pre-pregnancy overweight/obesity,hyperglycemia,high blood pressure and dyslipidemia.TG was the independent risk factor for GMS.HDL-C seemed to have less importance in identifying GMS.

Objective To investigate the characteristics of gray matter volume in Obsessive Compulsive Disorder (OCD) patients compared with healthy controls, and to explore the correlation between brain regions with altered gray matter volume and the patients'cognitive function and clinical symptoms. Method Thirty-six patients with first-episode OCD and 35 healthy controls who were matched by age, gender and education level were selected and examined by MATRICS Consensus Cognitive Battery (MCCB) and Yale-Brown Obsessive Compulsive Scale (Y-BOCS). The head MRI and the Voxel-based morphometry was used to test the volume of gray matter. The correlation analysis was conducted to analyze the correlation between brain areas with altered gray matter volume and patients'cognitive function and Y-BOCS results. Results Compared with the control group, the OCD group had increased gray matter volume in frontal parietal lobe (postcentral gyrus-L, precentral gyrus-L) (t=4.299, P<0.0005, voxels>100) and temporal-limbic system (fusiform gyrus-L, superior temporal gyrus-L, medial temporal lobe-L, parahippocampal gyrus-L) (t=4.841, P<0.0005, voxels> 100). Meanwhile, the volume of gray matter decreased in bilateral anterior cingulate gyrus (t=-4.181, P<0.0005, voxels>100). In the case group, there were a positive correlation between the volume of gray matter in the temporal lobo-limbic system and social cognition score (r=0.347,P=0.038) and a positive correlation between the volume of gray matter in the anterior cingulate gyrus and obsessions score (r=0.416,P=0.012). Conclusion Patients with OCD have abnormal gray matter volume in a wide range of brain regions, including the frontal parietal lobe, the temporal-limbic system, and bilateral anterior cingulate gyrus, among which the volume of gray matter in the temporal-limbic system is correlated with social cognition, and gray matter volume in the anterior cingulate gyrus is correlated with obsessions.
