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 evaluate the clinical effect of itraconazole in prevention of invasive fungal infections in allogeneic hema-topoietic stem cell transplantion .Methods In this retrospective study ,110 patients receiving allogeneic hematopoietic stem cell transplants were administed itraconazole or fluconazole for prevention of fungal infection .The occurrence and prognosis of invasive fungal infection ,and the side effect of both pyrroles were observed .Results Proven and probable invasive fungal infections occurred in 5 of 69 itraconazole recipients(7 .2% ) and in 8 of 41 fluconazole recipients(19 .5% ) during the first 180 days after transplanta-tion ,the difference had statistical significance(P<0 .05) .The fatality rate related to fungal infection had no statistical difference be-tween the two groups(2 .9% vs .7 .3% ) .The occurrence of itraconazole adverse reactions were more than fluconazole (26 .9% vs . 7 .0% ) ,and both itraconazole and fluconazole were well tolerated .Conclusion Itraconazole significantly reduces the incidence of inva-sive fungal infection in the patients receiving allogeneic hematopoietic stem cell transplants ,and it is a effective and safe prophylaxis .

Objective To evaluate the eradication rate and long-term therapeutic effect of a triple therapy consisted of cla-(rithromycin) (CLA), amoxicillin (AMO)and omeperazole on Hp infection,and explore the alternative therapeutic programs and their effects after first therapeutic failure.Methods A total of 92 children with Hp infection were divided into two groups: 70 children were given the triple therapy for one week (CLA group);Twenty-two children were given another triple therapy composed of metronida-(zoole) (MET), AMO and omeperazole for two weeks (MET group).All of the children were followed up for 1-30 months after the therapies ended.Children of the two groups who were therapeutic failure were given retreatment as follows.CLA triple therapy were given for one week to the children who were failure after MET triple therapy;increased doses of CLA with longer treatment course was given to the children who were failure after CLA triple therapy . A tetra therapy consisted of colloidal bismuth subcitrate (CBS), furazolidone (FUR) ,omeperazole and AMO was given to children in whom the retreatment failed.Results The Hp eradication rate of CLA group was 91.4%(64/70),and the Hp eradication rate of MET group was 72.7%(16/22).There was significant difference between eradication rate of the two groups(?~2=5.16 P

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.
