Objective To study the prevalence and risk factors of chronic kidney disease (CKD) among adults in Zhengzhou. Methods One thousand eight hundred and fifty five residents (≥ 20 years) from 4 communities in 4 districts of Zhengzhou city were randomly selected by using a stratified,multistage sampling. They were interviewed, and received physical examination and measurements of urine and blood for renal damage as well as risk factors. Results Eligible data of 1752 subjects were included in the study. After the adjustment of age and gender component, albuminuria was found in 5.78% of the subjects, hematuria in 8.19%, and reduced renal function in 1.58%. Male had lower prevalence of albuminuria and hematuria (4.37% vs 7.29%, X2=6.252, P=0.012; 5.08% vs 11.51%, X2=24.499, P<0.01), but higher prevalence of reduced eGFR(2.26% vs 0.86%, X2=5.830, P=0.016) as compared with female. The prevalence of albuminuria and reduced eGFR increased with age. The crude prevalence of CKD was 14.50%, while the standardized rate was 13.57%. The prevalence of female was higher than that of male (17.83% vs 9.59%, X2=23.132, P<0.O1), which also increased with age. The most common manifestations of CKD were hematuria and albuminuria. Gender, age, smoking, hypertension,diabetes mellitus, obesity and hyperuricaemia were independently associated with CKD. The awareness rate of CKD was 8.27% and only 7.09% of the subjects received treatment. Conclusions The prevalence of CKD is 13.57% and the recognition is 8.27% in urban adult population of Zhengzhou.lndependent risk factors associated with kidney damage are gender, age, smoking, hypertension, diabetes mellitus, obesity and hyperuricaemia.

Objective To investigate the prevalence of metabolic syndrome in patients with maintenance hemodialysis, and to analyze the potential risk factors. Methods The clinical data of 472 patients with maintenance hemodialysis from 7 blood purification centers were collected. Patients were divided into the MS group and the non-MS group. The demographic data , anthropometric examinations , dialysis prescription and results of laboratory were compared between these two groups. Multivariate Logistic regression analysis was performed to analyze the risk factors of MS. Results The morbidity of MS was 34.75%. There were significant differences in weight , waist circumference , waist-hip ratio , frequency of dialysis , time of hemodialysis perweek , urea reduction ratio, urea clearance index (Kt/v), iron, intact parathyroid hormone (iPTH), leukocytes, high sensitivity C-reactive protein (hs-CRP) between these two groups (P < 0.05, resectively). Multivariate Logistic regression analysis revealed that iron (OR = 1.084, P = 0.042), iPTH (OR = 1.754, P = 0.035), waist-hip 1ratio (OR = 2.013,P = 0.021), hs-CRP (OR = 4.245,P = 0.000)were correlated with MS. Conclusion The morbidity of MS in patients with maintenance hemodialysis is higher. Iron, iPTH, waist-hip ratio, hs-CRP are potential risk fctors of MS for the patients with maintenance hemodialysis.

Objective To evaluate the early diagnosis value of MRI combined with DSA in cirrhotic nodules (regenerative nodules, dysplastic nodules) becoming small hepatocellular carcinoma. Methods 40 patients diagnosed as cirrhosis and whose liver nodules detected by ultrasound were followed up as MR dynamic study. All patients were followed up by three dynamic contrast-enhanced MR scanning once every 3 months,and the changes of cirrhotic nodules were observed and analyzed in the signal. If MRI suggested cancerous nodules cirrhosis, hepatic artery DSA would be carried out. Results 40 patients were followed up for 1.5 to 3 years,all patients MR nodules were found in liver regeneration. Follow-up process, the dysplastic nodules were founded in 28 cases and the small hepatocellular carcinoma were founded in 18 patients. 16 cases of 18 patients with small hepatocellular carcinoma carried out routine DSA all had typical of hepatic arterial blood supply and angiogenesis, and were given to Integrated Traditional and Western intervention simultaneously. Conclusion Combined use of MRI-DSA in the evaluation of cirrhotic nodules had a definite value, and could find smaller hepatocellular carcinoma,provide the basis for smaller hepatocellular carcinoma therapy.

One hundred and twenty one patients on maintenance hemodialysis ( MHD) from Januaury 2004 to Januaury 2009 in our hospital were enrolled in the study. Demographic characteristics, clinical data and causes of disease were documented, the survival probability was estimated with Kaplan-Meier method and the prognostic factors were analyzed with Cox regression model. The median follow-up duration was 28. 9 months. The 1,3, 5-year survival rates were 93. 0% , 66. 5% and 45. 8% respectively. By Kaplan-Meirie analysis, cardiovascular disease (x2 =6. 582, P =0. 010) , age of starting dialysis (x2= 12.439, P= 0.002), urea clearance index Kt/V ( x2 =7.633, P=0.006) and albumin levels ( x2 = 4.512, P= 0.034) were closely related to prognosis. Cox regression analysis showed Kt/V, cardiovascular disease and age of starting dialysis were independent prognostic factors ( relative risk were 3. 204, 2. 994, 2. 543 respectively).
