Objective To study the effect of polysaccharide of Cipangopaludina chinensis on gray human cervix cancer cells(Hela cells) in vitro. Methods Polysaccharide of Cipangopaludina chinensis gray was extracted by water extraction. MTT assay and microscope were used to observe its effect on the growth inhibition of Hela cells at different concentrations of the polysaccharide. Results Polysaccharide of Cipangopaludina chinensis could more significantly inhibit the growth of Hela cells. Conclusion Polysaccharide of Cipangopaludina chinensis could inhibit human cervix cancer cells in vitro

Objective To investigate complications and mortality of primary reamed intramedullary nailing for femoral shaft fractures in patients a ssociated with thoracic injuries. Methods A retrospective a nalysis of trauma data was performed and the case selection based on the followi ng criteria: (1) patient age of 17-65 years, (2) patients with multiple injury ( ISS≥16) as well as complicated thoracic trauma (AIS≥2), (3) hospitalization stay ≥48 hours, (4)no serious pre-existing medical diseases in history, (5) as sociated femoral shaft fractures treated with reamed intramedullary nailing, ext ernal fixation, plate, cast, traction and unreamed intramedullary nailing. The s elected patients were divided into two groups according to the interval from inj ury to operation, ie, those within 24 hours as Group A and beyond 24 hours as Gr oup B. Results During the study period, 96 patients met the criteria for the investigation. There were 57 patients in the Group A and 39 pa tients in the Group B. In two groups, there was significant difference in incide nce of open femoral shaft fractures (53% in the Group A and 31% in the Group B, ? 2=4.496, P

Objective To investigate the prevalence of obesity and metabolic syndrome(MS)of children and adolescents in Longquan mountainous area in Zhejiang province.Methods A representative sample involving 2 135 children and adolescence aged 10 to 15 years were randomly surveyed and a total of 2 125 had available data(male/female ratios as:1 109/1 016).Using the standard methods,we measured the weight,height,waist circumference,hip circumference,blood pressure,detected fasting plasma glucose (FPG),high density lipoprotein cholesterol (HDL -C),triglyceride(TG),total cholesterol(TC),and calculated non-high density lipoprotein cholesterol(non-HDL). The prevalence of obesity and MS among the 10 to 15 years old children and adolescence in Longquan was compared with that in six cities in China(Beijing,Tianjin,Shanghai,Zhejiang,Chongqing and Guangxi).Results The preva-lence of obesity was 4.7% in 10 -15 -year -old teenage,in which the male obesity prevalence was 6.3%(70/1 109),female obesity prevalence was 3.0%(30 /1 016).The prevalence of overweight was 9.4% and the prevalence of boys was 11.0%,while the girl was 7.6%.The prevalence of obesity and overweight was 16.4%(299/2 125).The prevalence of MS was 2%(42/2 125)in the survey,but 42.0%in the obesity.The prevalence of obesity in Longquan(4.7%)was lower than that in the national six cities(8.1%)among the children and adoles-cents from 10 to 15 years old(χ2 =31.09,P=0.000).But in the obesity students,the prevalence of MS(42.0%)in Longquan was higher than that in six cities(28.8%)(χ2 =5.43,P=0.02).Conclusion The prevalence of obesity in Longquan mountainous area was lower than that in the national six cities among the children and adolescents from 10 to 15 years old.However,the prevalence of MS among the obesity in Longquan was higher than that in six cities.

Group A Streptococcus (GAS) is a very important pathogen, especially for children.On a global scale, GAS is an important cause of morbidity and mortality.But the burden of disease caused by GAS is still unknown in China and also has not obtained enough attention.For this purpose, the expert consensus is comprehensively described in diagnosis, treatment and prevention of GAS diseases in children, covering related aspects of pneumology, infectiology, immunology, microbiology, cardiology, nephrology, critical care medicine and preventive medicine.Accordingly, the consensus document was intended to improve management strategies of GAS disease in Chinese children.
