Nitrogen (N), phosphorus (P) and potassium (K) are three macroelements in agriculture production, but their combined effects on arsenic (As) toxicity and its translocation in rice plants are not clear. In this study, an orthogonal rotation combination based on different N, P and K (NPK) concentration was first designed to examine their combined effect on the As toxicity, its transformation and migration in rice plants based on the hydroponic culture and pot soil culture. The results showed that 2.

The results showed that the ΣPAHs of the road dust ranged from 48.85 to 166.

Nucleus accumbens-1 (NAC1), a nuclear protein of the BTB/POZ gene family, has pivotal roles in cancer development. Here, we identified that NAC1-PDK3 axis as necessary for suppression of mitochondrial function, oxygen consumption, and more harmful ROS generation and protects cancer cells from apoptosis in hypoxia.

Several methods were applied to assess the enrichment degree, pollution level and potential ecological risk of the above elements. The sources of the above elements were analyzed based on the multivariate statistical analysis combining Pb and Sr isotopic tracing technology.

The title compound, C26H21F3N2, was prepared by the palladium-catalysed reaction of (2,2,2-tri-fluoro-eth-yl)benzene with 1-methyl-1H-indole. The dihedral angle between the planes of the indole-ring systems is 52.13 (6)° and the N-methyl groups point away from each other.

An elderly female patient with diabetic nephropathy presented with severe pain, numbness, and an increasing swelling in the left hip and left thigh after six sessions of hemodialysis involving the use of an antiplatelet drug and an anticoagulant agent. Her hemoglobin decreased to 46 g/L.

Sichuan Da Xue Xue Bao Yi Xue Ban
November 2011
Objective: To investigate the effect of methylation modification on the mRNA expression of Cosmc gene in peripheral B lymphocytes from IgA nephropathy (IgAN).
Methods: Biopsy identified 22 cases of IgAN patients and 20 cases of normal control were included. Peripheral B lymphocytes were isolated and were cultured with RPMI1640 medium, with LPS (12.
External suppression causes the low expression of the Cosmc gene in IgA nephropathy.
Nephrol Dial Transplant
May 2008
Objective: IgA(1) aberrant O-glycosylation is one of the main pathogeneses of IgA nephropathy (IgAN), and the core I beta3-Gal-T-specific molecular chaperone (Cosmc) mRNA expression of IgAN patients was significantly decreased. This study tried to clarify whether the down-regulation was a result of genetic disorders or external suppressions.
Method: Sixty-five IgAN patients, 23 non-IgAN glomerulonephritis patients and 21 normal controls were recruited.
[Inflammatoin, oxidative stress and carbonyl stress in uremic patients].
Sichuan Da Xue Xue Bao Yi Xue Ban
January 2006
Objective: To evaluate the states of inflammation, oxidative stress and carbonyl stress in uremic patients and analyze their relationships.
Methods: One hundred and twenty-eight cases were divided into 6 groups: non-dialysis uremia group (n=25), peritoneal dialysis group (n=19), hemophan(Hem) membrane dialysis group (n=25), polyamide (PS) membrane dialysis group (n=25), diabetes with normal renal function group (n= 23) and normal control group (n=11). Spectrophotometry and immune turbidimetry were used to measure the serum SOD, VitC, VitE, MDA and total carbonyl compounds (TCC) levels.
[Effect of high glucose on the expression of fibronectin and plasminogen activator inhibitor-1 in human peritoneal mesothelial cells].
Sichuan Da Xue Xue Bao Yi Xue Ban
September 2005
Objective: To evaluate the effect of high glucose on the expression of fibronectin (FN) and plasminogen activator inhibitor-1 (PAI-1) in human peritoneal mesothelial cells (HPMC).
Methods: The cultured HPMC were exposed to the culture medium containing different concentrations of glucose (1.5%, 2.
[Epidemiology of cardiovascular risk in Chinese chronic kidney disease patients].
Zhonghua Yi Xue Za Zhi
March 2005
Objective: To identify the risk factors associated with cardiovascular disease (CVD) in Chinese chronic kidney disease (CKD) patients.
Methods: As part of a multicenter Chinese cohort study, the clinical data associated with CVD of 1239 patients with CKD (stage 2 - 5) hospitalized in 7 grade 3A hospitals distributed in 5 regions of China 2002 - 2003 were collected. Logistic regression model was used to analyze the association between CVD and the demographic variables, lifestyle, medical history, medication, physical examination, and laboratory variables.

Zhonghua Yi Xue Za Zhi
February 2005
Objective: Cardiovascular (CV) disease (CVD) is the single most important cause of death among Chinese dialysis patients, accounting for 51% of overall mortality. The study was performed to investigate the prevalence and the spectrum of CVD in Chinese chronic kidney disease (CKD) patients.
Methods: The multicenter Chinese cohort study examined 1239 CKD patients from 7 main medical centers (distributed in 5 regions of China) who were hospitalized between 2002 and 2003.
