The Modification of Diet in Renal Disease (MDRD) equations provide a rapid method of assessing GFR in patients with chronic kidney disease (CKD). However, previous research indicated that modification of these equations is necessary for application in Chinese patients with CKD. The objective of this study was to modify MDRD equations on the basis of the(More)
BACKGROUND Chronic kidney disease (CKD) is considered a serious worldwide public health problem, but data from developing countries are extremely limited. STUDY DESIGN Cross-sectional study. SETTING AND PARTICIPANTS A representative sample of 13,925 adults in Beijing, China. PREDICTORS Age (18 to 39, 40 to 59, 60 to 69, and >70 years), sex, urban or(More)
The clustered organization of Hox genes provides a powerful opportunity to examine gene gain and loss in evolution because physical linkage is a key diagnostic feature which allows homology to be established unambiguously. Furthermore, Hox genes play a key role in determination of axial and appendicular skeletal morphology and may be a key component of the(More)
BACKGROUND Chronic kidney disease (CKD) is a public health problem, while data from developing countries are limited. We sought to investigate the epidemiological features of kidney damage in metropolis-residing Chinese adults (>40 years old), and to determine the associated factors of CKD. METHODS Two thousand three hundred and fifty-three residents in(More)
An equation from the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) provides more accurate estimates of the glomerular filtration rate (eGFR) than that from the modification of diet in renal disease (MDRD) Study, although both include a two-level variable for race (Black and White and other). Since creatinine generation differs among ethnic(More)
OBJECTIVE To explore the relationship between metabolic syndrome and chronic kidney disease (CKD) in a study population from a developing country. PARTICIPANTS AND METHODS The prevalence of metabolic syndrome (as most recently defined by the International Diabetes Federation) and CKD (defined as an estimated glomerular filtration rate of < 60 mL/min per(More)
BACKGROUND To evaluate whether the Modification of Diet in Renal Disease (MDRD) equations could be applied accurately to Chinese patients with chronic kidney disease (CKD), glomerular filtration rates (GFRs) estimated by using MDRD equation 7 (7GFR), the abbreviated MDRD equation (aGFR), and the Cockcroft-Gault equation (cGFR) were compared in patients with(More)
BACKGROUND Renal replacement therapy is rapidly expanding in China, and two-times weekly dialysis is common, but detailed data on practice patterns are currently limited. Using cross-sectional data from the China Dialysis Outcomes and Practice Patterns Study (DOPPS), we describe the hemodialysis practice in China compared with other DOPPS countries,(More)
DNA comprising 219 447 bp was sequenced in nine cosmids and verified at > 99.9% precision. Of the standard repetitive elements, 187 Alus make up 20.6% of the sequence, but there were only 27 MERs (2.9%) and 17 L1 fragments (1.6%). This may be characteristic of such high GC (57%) regions. The sequence also includes an 11.3 kb tract duplicated with 99.2%(More)
The exact pathogenesis of Parkinson's disease (PD) is still unknown and proper mechanisms that correspond to the disease remain unidentified. It is understood that PD is age-related; as age increases, the chance of onset responds accordingly. Although there are no current means of curing PD, the understanding of reactive oxygen species (ROS) provides(More)
