Objective To investigate the expression of hypoxia inducible factor-1α(HIF-1α) and vascular endothelial growth factor C(VEGF-C) in colon carcinoma,and their relation with clinical pathological parameters and prognosis. Methods Immunohistochemistry was used to detect the expression of HIF-1α and VEGF-C in 65 tissues of colon carcinoma. Results In all cases,the expression of HIF-1α had a positive correlation with the expression of VEGF-C(r= 0.638,P＜0.01).The expressions of HIF-1α and VEGF-C had significant correlation with clinical stage and nodal metastasis(P＜0.05) ,but had no relationship with sex,age and tumor size(P＞0.05). Conclusion The expression of HIF-1α and VEGF-C was correlated with nodal metastasis, tumorigenesis and prognosis of colon/carcinoma.

Objective To investigate the correlation of anthropometric indicators and blood pressure in children. Methods A total of 6 790 children aged 6 to 13 years were inspected by random sampling. The body mass index (BMI), waist circumference (WC), hip circumference (HC), and blood pressure were measured. The waist/hip ratio (WHR) and waist/height ratio (WHtR) were calculated. The data wrer analyzed by SPSS16.0 statistical software. Results The detection rate of hypertension in children was 5.57%. After controlling for age, both in male and female children, the BMI, WC, HC, WHR, WHtR and systolic blood pressure showed a significant positive correlation by partial correlation analysis (all P<0.05). Both in male and female children, the BMI, WC, HC, WHR, and WHtR were significantly higher in children with hypertension than those in children with normal blood pressure (all P<0.05). Among all subjects, 280 children (4.12%) were obese, 622 children (9.16%) were overweight. The detection rates of hy-pertension were significantly different among obese, overweight and normal weight children (P<0.01). The detection rate of hypertension was significantly higher in obese children than that in overweight and normal weight children. The systolic and diastolic blood pressure were all significantly higher in obese and overweight children than that in normal weight children (P<0.05). Conclusion The hypertension prevalence of children aged 6 to 13 years in Zhengzhou is in the low to median level in the same age groups. The BMI, WC, HC, WHR, WHtR are signiifcantly correlated with blood pressure in both gender, and the correlation is the most obvious in HC.

ObjectiveTo understand the feature of blood pressure in children aged 7 to 12 years in Zhengzhou.Methods According to stratiifed cluster random sampling method, children aged 7 to 12 years in ifve schools from three urban and two suburban counties in Zhengzhou were analyzed. The height, weight, waist circumference, hip circumference, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were measured and analyzed.Results The survey included total 6460 children aged 7 to 12 years, 3206 urban children (49.63%), 3254 suburban children (50.37%), 3525 boys (54.57%) and 2935 girls (45.43%). SBP in boys [(117.86±18.18) mmHg] was signiifcantly higher than that in girls [(113.82±13.11) mmHg (t=3.16;P=0.002). The incidence of hypertension in children in Zhengzhou was 7.52%. The blood pressure in boys was higher than that in girls (χ2=9.66,P=0.002). The blood pressure in urban boys and girls was higher than that in suburban boys and girls respectively (χ2=24.15, 14.39;P=0.000). The SBP and DBP had positive correlation with age, height, weight, BMI, waist circumference in boys (P<0.01). The SBP had positive correlation with age, height, weight, BMI, waist circumference in girls (P<0.01). Conclusions The blood pressure is higher in boys than in girls, which also is higher in urban children than in suburban children in Zhengzhou. The SBP is related to the age, height, weight, BMI, waist circumference.

Objective To compare the clinical effect between CO2-1aser assisted and cold instrument assisted suspension laryngoscopic surgery for vocal fold cyst.Methods From January, 2011 to December, 2014, 72 patients with vocal fold cyst, which diagnosed by strobolaryngoscopy, were randomly divided into CO2-1aser assisted group and cold instrument group.Strobolaryngoscopy, acoustic analysis and perceptual voice analyses were performed on each patient before surgery, 1 month, and 3 months after surgery, respectively.Results All operations were successfully completed.The complete vocal fold cyst resection rate of CO2-1aser assisted group was significantly higher than cold instrument group (29/36, 80.5％ vs 21/36, 58.3％, P ＜ 0.05), especially the left vocal fold cyst (13/16, 81.3％ vs 9/19, 47.4％, P ＜ 0.05).The complete right vocal fold epidermoid cyst resection rate was significantly higher than retention cyst (17/19, 89.4％ vs 11/18, 61.1％, P ＜ 0.05).Two recurrent cases were found in cold instrument group but no recurrent cases in CO2-laser assisted group (0/36, 0％ vs 2/36, 5.6％, P ＞ 0.05).Correlation analysis showed that vocal fold cyst recurrence was related to complete resection rate and has no relation with surgical methods, histopathological types and position.Subjective and objective assessment of voice quality in preoperative, 1-month postoperative and 3-month postoperative were similer between CO2-1aser assisted group and cold instrument group (P ＞ 0.05).Conclusion The CO2-laser assisted suspension laryngoscopic surgery for vocal fold cyst, can increase the surgical precision, reduce the left hand impact, improve the complete resection rate and reduce the recurrence rate.

Objective To compare the pre-existing mutations in reverse transcription region of HBV in patients with different HBV infection stages.Methods Totally 474 patients with chronic HBV infections,including 205 with chronic hepatitis B (CHB),153 with liver cirrhosis and 116 with hepatocellular carcinoma (HCC),were enrolled from the People' s Hospital of Shangyu and the First Affiliated Hospital of Zhejiang University during January 2011 and June 2013.All patients had not received nucleos (t)ide analogues treatment.HBV RT region mutations and genotypes were determined by PCR followed by sequencing.SPSS14.0 was used for statistical analysis.Results There were 387 (81.6％) patients with HBV genotype B,in which 156 were with CHB,124 were with liver cirrhosis,and 107 were with HCC.Nucleos(t)ide analogues-related mutations were observed in all the above 387 patients.rtS106C mutation was more popular in CHB and liver cirrhosis (14.1％ and 14.5％) patients than that in patients with HCC (4.7％) (x2 =6.126,6.207,P ＜0.05); And the positive rates of rtD134E/G/N/S mutations were also higher in CHB and cirrhotic patients (21.8％ and 20.2％) than that in HCC patients (10.3％,x2 =5.933,4.263,P ＜ 0.05).rtD134E/G/N/S and rtS106C mutations were correlated with HBeAg (P ＜0.01) and gender (P ＜ 0.05),but not with HBV virus load and age (P ＞ 0.05).The mutation frequencies in A-B interdomain were higher in CHB and cirrhotic patients (5.3％ and 5.6％) than that in HCC patients (3.5％,x2 =9.018,11.018,P ＜ 0.01).Conclusions Nucleos (t) ide analogues-related mutations exist in various HBV infection stages.rtSl06C and rtD134E/G/N/S mutations may be involved in necro-inflammation,and A-B interdomain mutations may be correlated with necro-inflammation,immune response and fibrosis in chronic liver diseases.
