Objective To evaluate the value of nuchal translucency (NT) thickness in the fetal chromosome abnormality screening. Methods 11 086 pregnant women received NT measurement in 11 ~ 13+6 weeks at Hainan general hospital from January 2010 to December 2014 were selected in the study. The NT thickness was measured according to guidelines from Fetal Medicine Foundation. 122 fetuses (NT≥2.5 mm) were recruited to accept karyotype analysis. Results 11 086 pregnant women received NT measurement in 11 ~13+6 weeks, in which 122 cases′ NT are more than or equal to 2.5 mm, with a positive rate of 1.10%. 122 cases of fetal NT thickening are between 2.5 to 12.0 mm, with the average degree at (4.5 ± 2.1)mm. 122 invasive prenatal diagnostic specimens chromosome karyotype analysis results showed chromosomal abnormalities in 21 cases (abnormal rate of 17.2%), the abnormal chromosome number in 17 cases and abnormal structure in 4 cases. The top 3 are trisomy 21 (12 cases, 57.1%), chromosome pericentric inversion (3 cases, 14.3%), and trisomy 18 (2 cases, 9.5%). Fetal chromosomal abnormalities resulting from different childbirth age, the sex of the fetus, NT thickness showed significant statistical difference (P < 0.05). The concrete manifestation is that fetal chromosomal anomaly detection rate in childbirth by women more than 35 years old age are higher than other age. Female fetal chromosomal anomaly detection rate is higher than the male , and NT thickness of 5mm of fetal chromosomal abnormality rate is significantly higher than the thickness of NT group at 2.5mm~ and 3.5mm~. Fetal NT thickening of NT measurements was in significant positive correlation with fetal chromosome abnormal rate (χ2=15.533, P < 0.001). Logistic regression analysis found that with a higher NT thickness , risk of fetal chromosomal abnormalities would be significantly higher , and thickening of NT could be an independent predictor of fetal chromosome abnormalities. Conclusion In early pregnancy, ultrasound examination of fetal ultrasound screening of NT thickness can be used as an important index of fetal chromosomal abnormality , and interventional diagnosis of prenatal NT thickness increase could pose increased risk of fetal chromosomal abnormalities.

The hypoglycemic activity and its mechanism of Jatrorrhizine (Jat) were studied. The normal mice and alloxan-induced hyperglycemic mice were given with different doses of Jat. Blood glucose and liver glycogen levels were determined by spectrophotometry with glucose-oxidase and iodine reagents respectively. The levels of blood lactic acid (LC) and liver lactate dehydrogenase (LDH) activity were measured to explore the effect of Jat on anaerobic glycolysis. Succinate dehydrogenase (SDH) activity in liver was measured to evaluate the effect of Jat on aerobic glycolysis in liver. It was found that Jat (50 mg/kg, 100 mg/kg) could significantly decrease blood glucose level in a dose- and time-dependent manner in both normal and alloxan-diabetic mice, increase the activity of SDH, but had no significant effects on the LC level and LDH activity. Jat could significantly reduce the content of liver glycogen in normal mice. Moreover, Jat could inhibit the platelet aggregation in rabbits in vitro in a dose-effect relationship. It was concluded that Jat induced the pronounced decrease in blood glucose in normal and hyperglycemic mice. The hypoglycemic activity of Jat may be attributed to the enhancement of aerobic glycolysis.

Objective To compare proprotein convertase subtilisin/kexin type 9 (PCSK9) levels between premenopausal and postmenopausal women,and to investigate the relationship between serum PCSK9 and metabolic factors.Methods Totally 515 women were enrolled from the study on diabetes of prediction,prevention,and intervention in Nanjing in 2009.Survey,physical examinations,and determination of related metabolic indexes were performed.Serum PCSK9 level was measured by sandwich ELISA.Results Serum PCSK9 level was positively correlated with low density lipoprotein-cholesterol (LDL-C),total cholesterol (TC),triglyceride,fasting plasma glucose,body mass index,waist-hip ratio,and age in women (all P＜0.01).PCSK9 level was significantly lower in premenopausal women than that in postmenopausal women [(58.18 ± 25.44 vs 80.91 ± 33.74) ng/ml,P ＜0.01].Conclusion Higher level of PCSK9 exists in postmenopausal women compared with premenopausal women.The level of PCSK9 is closely correlated with age,TC,and LDL-C.

ObjectiveTo investigate the role of active protein C (APC) in lipopolysaccharide (LPS) induced microglia activation.MethodsMicroglia from one day old Sprague-Dawley newborn rat was collected, purified and identified by primary culture and immunofluorescence staining, and then was randomly divided into four groups including LPS group (1.0μg/ml LPS plus 10μl phosphate buffered saline 12 h later), LPS+ APC group (1.0μg/ml LPS plus 0.1μg/ml APC 12 h later), APC group (10μl phosphate buffered saline plus 0.1μg/ml APC 12 h later) and control group (10μl phosphate buffered saline at each time point). The morphology of micaroglia in all groups was observed under microscope, and the expression of tumor necrosis factor-α (TNF-α) and protease-activated receptor-1 (PAR-1) were determined by immunofluorescence staining. One-way analysis of variance and LSD test were applied for statistical analysis.ResultsPrimary culture microglia was successful and the purity was no less than 99%. In LPS group, the microglia morphology was activated, and the expression of TNF-α was increased significantly than the control group (2.11±0.35 vs 1.38±0.28, LSD test,P=0.002). In LPS+APC group, the microglia morphological change was reversed, and the expression of TNF-α had no significant difference with the control group (1.35±0.36 vs 1.38±0.28, LSD test,P>0.05). The expression of PAR-1 in LPS+APC group was higher comparing with that in the control group (4.60±0.84 vs 2.64±0.41, LSD test,P=0.008) and the LPS group (2.44±0.86, LSD test,P=0.002). The expression of PAR-1 in APC group and LPS group had no obvious difference with control group (2.62±0.69, 2.44±0.86 vs 2.64±0.41, LSD test, bothP>0.05).ConclusionsBy increasing the level of PAR-1 in microglia, active protein C could inhibit the activation of miciroglia and the expression of TNF-α induced by lipopolysaccharide, therefore, protecting the brain tissues from inflammation-induced damage.
