Objective To explore the multiple risk factors for family lifestyle of children with congenital heart defects (CHDs) in Shaanxi Province, China. children and their parents. The univariate and multivariable logistic regression models were used to analyze the influence of risk factors related to parents' lifestyle on CHDs. Results Several possible risk factors were found for CHDs, including fever (OR=4.465, P=0.017), pesticides contact (OR=2.234, P=0.083), passive smoking during pregnancy (OR=20.529, P=0.007) and father's smoking (OR=3.342, P=0.005); fever (OR=2.428, P=0.012) and passive smoking during pregnancy (OR=1.201, P=0.037) were also correlated with ventricular sepal defect (VSD). Conclusion Fever, pesticides contact and passive smoking are associated with CHDs during pregnancy. We should focus our attention on health care during pregnancy to avoid the above-mentioned risk factors and call on parents to hold on to a good healthy lifestyle.

Chondrosarcomas has low morbidity in China,but we should pay more attention to the results it contributed to.Patients usually have poor prognosis because of defect of surgical resection and resistance to con-ventional chemotherapy and radiotherapy.Chemotherapy is a significant method to the chondrosarcoma treatment. If we overcome the difficulty of chemoresistance,chemotherapy will kill the sarcoma cells efficiently and inhibit the capacity of metastasis and invasion.The patients will have better prognosis.Finding the mechanisms of che-moresistance in chondrosarcomas is the key, now we review sevaral recent mechanisms of chemoresistance in chondrosarcoma.

Objective To establish a calcification mode in vitro of human vascular smooth muscle cells (HVSMCs) induced by β-GP. Methods Primary HVSMCs were obtained from human embryo by plant method and confirmed by stain with α-sm-actin antibody. The cells after 4-6 passages were divided into two groups.The control group was incubated with normal DMEM medium while the calcification group was incubated with the medium containing 10 mmol/L β-glycerophosphate for 10 days.Calcification was confirmed by alizarin red S stain and alkaline phosphatase(ALP) assays. Results The primary cells observed by S-P stain were positive and the cells after being stained were pale yellow. After being induced with β-GP, the cells of calcification group began concentric growth and formed vesicles. Alizarin red S staining showed that the reaction of calcifying nodules was red,ALP activity was higher than that of controls at various time points(4 d,6 d,8 d and 10 d,P＜0.01 ).Conclusion The HVSMCs could be induced into calcification in vitro by β-GP, and this model contribates to further studies of vascular diseases.

A temperature-sensitive mutant strain was isolated after transposon mutagenesis with Tn5 and named MT54.PCR was carried out with primers designed according to the sequence of transposon,the PCR products showed that the MT54 carried transposon in the genome. The mutant grew well at 30℃in minimal medium(MM)containing p-nitrophenol(PNP)as sole carbon source,while it cannot grow at 37℃in the same medium,NO_2.detection results also proved that.Comparing the degradation rate of PNP and hydroquinone of MT54 and DLL-E4 at different temperature,it was speculated that the mutant site locate in the PNP degradation related genes.

Significant correlation was found between high awakening factor and SDQ emotional factor and depression scale total score. Conclusion The reliability and validity of CRIES-13 was good. It could be used extensively.

Objective The Children's Revised Impact of Event Scale (CRIES-13) is used for Screening PTSD of children. The reliability and validity of CRIES-13 is good. To research the demarcation points of CRIES-13 (Chinese version) based on the reliability and validity analysis,and to improve the useful value of the scale.Methods In late September 2008, according affected condition, students were choosed who were fit for the research standard as subjects in two middle schools. First,general questionnaire (self-writing) and CRIES-13 were applied to the subjects. Second, according to K-SADS-PL, physician carried out diagnosis meeting and evaluation to 310 students who were classified by stratified rand sampling. Critical point of CRIES-13 was divided by K-SADSPL. The assessment value of it were sensitivity, specificity, veracity, PPV, NPV. The right choice of division was measured by ROC curve. Results When the critical score was higher than 30, the score of Se ( 0. 833 ), Sp(0. 836) and NPV (0.97) was in the high level. Conclusion When the critical score is higher than 30, the scale have a good discrimination for PTSD, non-PTSD and it can be used extensively.

Objective To explore the clinical significance of sCD14-ST in diagnosing children sepsis and monitoring the treatment effects. Methods Case-control study. Patients were recruited by Longyan First Hospital from August 2013 to March 2015.The sCD14-ST, WBC, CRP, PCT and APACHE-Ⅱlevels were measured in 237 septic children ( infectious SIRS, including 120 bacterial and 117 nonbacterial SIRS) , 89 non-infectious SIRS and 156 healthy children.The changes and the correlation of the five indicators in septic children before and after treatment was compared.The diagnosis value of sCD14-ST in sepsis by the receiver operationg characteristic curves ( ROC) was analyzed.Results The sCD14-ST level in septic children [643.47(596.47 -690.46) ng/L] was higher than that in non-infectious SIRS [246.94(234.85-259.03)ng/L]and healthy control [151.00(142.79-159.22)ng/L](χ2 =121.850, 325.663, P<0.01).The whole blood level of sCD14-ST in bacterial sepsis [606.17(542.71-669.63) ng/L]and non-bacterial sepsis [679.83(610.37-747.29)ng/L]were no significance (χ2 =0.854, P=0.335), while compared with the control group, they had significant differences (χ2 =326.228, P<0.01) .Totally 80 blood culture samples were positive in 117 bacterial septic children, and the sCD14-ST level was not significant between Gram positive bacteria infection and [641.07 (553.82 -728.31) ng/L] Gram negative bacteria infection[750.00(597.10 -902.89) ng/L] (χ2 =1.12,P=0.29), but the sCD14-ST level in blood culture positive children was significantly higher than healthy controls ( chi-square =117. 46, 155.846, P<0.01).sCD14-ST, WBC, CRP, PCT, APACHE-Ⅱscore before and after treatment were all significantly decreased ( χ2 =44.569, 113.337, 63.986, 100.055, 51.015, P<0.01).The sCD14-ST was significantly positively related withCRP and APACHE-Ⅱ score before treatment, but there were no correlation with WBC and PCT.The ROC-AUC of sCD14-ST in septic children was 0.901.Compared with the ROC-AUCs of WBC ( 0.875 ) and CRP ( 0.836 ) , there were statistically significant different ( P<0.01).The sensitivity and specificity of sCD14-ST were 85%, 90%, respectively.Conclusions The study suggested that sCD14-ST superior value to the diagnosis of sepsis in children than other parameters.It should be applied as a valuable biomarker for early diagnosis and the evaluation of severity of sepsis.

Objective To evaluate global and segmental right ventricular ( RV ) systolic functions in patients with excessive volume or pressure load using real‐time three‐dimensional echocardiography ( RT‐3DE) . Methods Forty‐five patients with RV volume overload ,45 patients with RV pressure overload and 45 healthy subjects were underwent RT‐3DE . RV global and segmental ( inflow ,body ,outflow ) end‐diastolic volume (EDV) ,end‐systolic volume (ESV) ,stroke volume (SV) and ejection fraction (EF) were analyzed with TomTec software . The correlations between EF with the three‐dimensional method and two‐dimensional parameters including right ventricle systolic pressure( RVSP) were discussed . Results Global EDV and ESV increased significantly in both patient groups compared with controls ( all P < 0 .05) ,but there was no difference between two patient groups ( P >0 .05) .Compensated increase of SV was found in sixty percent of patients with volume overload but none with pressure overload ( P < 0 .05) . Global EF decreased significantly in both of patient groups (all P <0 .05) ,which was more significant patients with pressure overload ( P < 0 .05 ) . Different patterns of the regional dysfunction were found among the different RV segments . No correlation was found between RVSP and global or segmental EF in patients with pressure overload . Conclusions RT‐3DE could be used to assess global and segmental RV systolic function in patients with pressure and volume overload .
