Chinese Journal of Perinatal Medicine 2011;14(3):166-169
Objective To investigate the relationship between early pregnancy fasting plasma glucose (FPG) and gestational glucose metabolism disorders. Methods Six hundred and fifty-six pregnant women who were singleton, non-diabetes before pregnancy and had FPG examined during 5-13 weeks of pregnancy were admitted into this study from January 1, 2009 to May 31, 2009. All these subjects had routine prenatal examination and finally delivered in the Department of Obstetrics of Peking University First Hospital. The FPG, 50 g glucose challenge test (GCT) after 24 weeks of pregnancy, 75 g oral glucose tolerance test (OGTT), gestational diabetes mellitus (GDM),gestational impaired glucose tolerance (GIGT) were analyzed with receiver operating characteristic (ROC) curve. Results (1) Relationship between FPG and GCT were analyzed with ROC curve.The maximum area under curve was 0. 539 (95% CI: 0. 493-0. 586) and there was no correlation between the FPG and GCT results(P=0. 057). (2) Relationship between early pregnancy FPG and abnormal FPG examined after 24 gestational weeks were also analyzed . The maximum area under curve was 0. 796(95% CI: 0. 672-0. 920). If 5. 05 mmol/L was taken as the cutoff value, the sensitivity and specificity was 54. 5% and 83. 2%, respectively. There was significant relationship between the two values (r=0. 432, P=0. 000). (3) There were no relationship between early pregnancy FPG and the blood glucose value of 1, 2 and 3 h in 75 g OGTT (r=0. 093, 0. 036 and 0. 107, P=0.122, 0. 549 and 0. 074 respectively). OGTT 0 h value was positively related to OGTT 1, 2 and3 h glucose level (r=0.493, 0.421 and 0.368, P=0.000, respectively). (4) All early pregnant FPG values in this study were under 6.1 mmol/L. Twenty-two GDM and 27 GIGT patients were diagnosed in this study. Early pregnancy FPG did not relate to the GDM and GIGT diagnosis.Conclusions Early pregnancy FPG could not replace 50 g GCT as an early screening for glucose metabolic abnormality in pregnancy, but FPG during early pregnancy is necessary.

Objective To investigate the effect of scalp acupuncture plus real-time cognitive training on cerebral blood flow in Alzheimer disease patients with cognitive disorder.Methods One hundred Alzheimer disease patients with cognitive disorder were randomly allocated to treatment and control groups, 50 cases each. Both groups received treatment for the primary disease. In addition, the treatment group received scalp acupuncture plus real-time cognitive training and the control group took Ginkgo leaf extract tablets. Mean flow velocity (Vm) in the left vertebral artery (LVA), right vertebral artery (RVA) and middle cerebral artery (MCA) were measured using transcranial Doppler in the two groups of patients before and after three months of treatment.Results There were statistically significant pre-/post-treatment differences in LVA, RVA and MCA Vm in the two groups (P<0.01). There were statistically significant post-treatment differences in LVA, RVA and MCA Vm between the treatment and control groups (P<0.05).Conclusions Scalp acupuncture plus real-time cognitive training can improve cerebral circulation and increase cerebral blood flow in Alzheimer disease patients with cognitive disorder.

Objective:To explore the relationship between cognitive deficits and oxidative stress in male patients with heroin dependence (MPHD). Methods: The cognitive function of 140 MPHD and 75 healthy controls were evaluated with Wechsler Memory Scale (WMS), Cancellation Test (CT) and Modified Wisconsin Card Sorting Test (M-WCST). The levels of serum nitric oxide (NO) and malondialdehyde (MDA) were detected in colorimetry. Results:The performances of WMS, CT and M-WCST in MPHD were significantly lower than that in healthy controls (93.7?13.8/102.9?12.3, t=-2.83; 161.6?32.8/194.4?26.5, t=-4.28; 18.8?7.8/25.0?7.5, t=-3.38, P

Objective:To investigate the hippocampus neuron injury,mitochondrial function and mitochondrial apoptosis related protein expression in kainic acid(KA) induced epilepsy rat,and to explore the role of mitochondrial pathways of apoptosis in the neuron injury.Methods:KA induced epilepsy model was produced by injection of KA into the hippocampus.Forty SD rats were randomly divided into five groups: control and KA group(6 h,1 d,3 d and 7 d),n=32.The concentration of Glu in hippocampus CA3 area was detected by HPLC.The apoptosis of hippocampus neurons and the concentration of free calcium ion were assayed by flow cytometry.The expression of cytochrome C and caspase-9 in hippocampus CA3 area was determined by Western blot.Results: ①The concentration of Glu in hippocampus CA3 area was increased in the fourth day after KA injection.②The concentration of free calcium ion,mitochondrial membrane potential,and the number of apoptosis neurons was significantly changed after 6 h of KA injection.Seven days after KA injection,these changes were more significant.③The hippocampus neuron expressed low levels of cytochrome C and caspase-9,and the expression of cytochrome C and caspase-9 was dramatically increased in a time dependent manner which increased by 4.37and 3.20 fold 7 d after KA injection.Conclusion:Mitochondrial pathways of apoptosis involve in hippocampal neuron apoptosis in KA induced epilepsy rat.
