RESUMEN
Objective To investigate the prevalence and associated risk factors of hypertension in Songnan community so as to provide evidence for the early prevention of hypertension.Methods Cluster sampling was employed,and questionnaire survey was performed in 10 185 residents aged above 40 years in Songnan community of Baoshan District.The questionnaires involved with hypertension and associated risk factors.Results The prevalence of hypertension was 49.9% in Songnan community of Baoshan District,and that of men was significantly higher than that of women(53.7% vs 47.3%)(P
RESUMEN
Objective To inquire and compare the value of 4 proteins in the cerebrospinal fluid (CSF) for early diagnosis of Creutzfeldt-Jakob disease (CJD).Methods The CSF samples were obtained from 14 CJD patients in the early stage,t-tan,t-tan,t-tau/t-tau,S-100?,14-3-3 and 14-3-2 protein had been examined and compared with other dementia (OD) and none dementia (ND) as controls by capture assay and ELISA.Results (1)t-tan protein: the concentration in CJD ,OD and ND is 8295,300 and 161 pg/ml respectively,t-tau/t-tau ratio is 0.0092,0.2258 and 0.2471 respectively.(2) S-100? protein: the concentration in CJD,OD and ND is 1.576,0.639 and 0.239 ng/ml respectively.(3) 14-3-3 protein:the concentration in CJD,OD and ND is 40.00,2.65 and 3.10 ng/ml respectively.(4) 14-3-2 protein: the concentration in CJD,OD and ND is 48.43,14.00 and 20.50 ng/ml respectively.(5) At the cut-off point 500 pg/ml for t-tan,sensitivity for diagnosis of CJD is 84.6% and specificity is 87.6% ,t-tan has no diagnostic value to CJD.(6) At 1.626 ng/ml for S-100?,the sensitivity is 92.3% and specificity is 83.8%.(7) At 9 ng/ml for 14-3-3 protein,the sensitivity is 86.7% and specificity is 86.4%.(8) At a level of24 ng/ml for 14-3-2 protein,the sensitivity for diagnosis of CJD is 78.6% and specificity is 77.3%. Conclusion It is the CSF detection of neuroproteins that have great valuble significance in diagnosis for sporadic CJD in the early stage.
