ABSTRACT
Objective To evaluate the effect of increasing sunshine time or 1, 25(OH)2D3 supplement on improving Vitamin D blood level and reduction of microalbuminuria in early stage diabetic nephropathy (DN) patients. Methods A total of 150 early stage type 2 DN patients with serum 25(OH)D3 lower than 15 mg/L were included.The patients were divided into sunshine group (n=50), 1, 25(OH)2D3 supplement group (n=50), and control group (n=50).After three-month treatment, serum 25(OH)D3 level and urinary albumin to creatinine ratio(ACR)were compared among these three groups. Results Before treatment, there were no differences in serum 25(OH)D3, ACR, HbA1c among the three groups.After three-month treatment, serum 25(OH)D3 level was significantly improved in sunshine group, and ACR was reduced significantly in both sunshine group and 1, 25(OH)2D3 group. Conclusion Increasing sunshine time can improve Vitamin D level and reduce microalbuminuria in early stage diabetic nephropathy patients.
ABSTRACT
A predominant chrysene-degrading strain was isolated and screened from biological sludge sampled from a coking plant,which can use chrysene as sole carbon source for growth in the selective culture me-dium.The phylogenetic tree of the strain was produced on the basis of morphology observation by SEM,experimental results of physiology and biochemistry and analysis of 16S rDNA sequence.The strain was identified as Achromobacter xylosoxidans.The effect of initial concentration of chrysene solution,inoculat-ing dose and pH on degradation efficiencies was investigated.The results indicate that the degrading charac-teristics of the strain is fine.The optimal degrading conditions are:initial concentration of chrysene solution 40 mg/L,inoculating dose(V/V)10%,pH 7.0~7.5,respectively.Under the optimal conditions,the degrading efficiency can reach more than 80% after 5 days at 30?C.
