Objective To evaluate the association of the 5'-end dinucleotide repeat polymorphisms of the aldose reductase gene and susceptibility to diabetic nephropathy in Chinese patients with type 2 diabetes mellitus by means of meta analysis. Methods Genetic association studies evaluating the 5'-end dinucleotide repeat polymorphism of the aldose reductase gene and susceptibility to diabetic nephropathy in type 2 diabetes mellitus patients involving Chinese population published before April 2007 were collected from database of PubMed, EMBASE, and CNKI. All the literatures were abstracted based on the defined selection criteria by two independent investigators. Publication bias was tested by funnel plot and the odd ratios of all studies were combined depending on the result of heterogeneity test among the individual studies. The software Review Manager (version 4.2) was used for meta analysis. Results Eight studies involving 5'-end dinucleotide repeat polymorphism of the aldose reductase gene and susceptibility of diabetic nephropathy in Chinese patients with type 2 diabetes mellitus met the selection criteria. There was no significant publication bias in selected studies. Heterogeneity test showed that there were significant statistic differences among the individual studies about the frequencies of Z-2 (χ2=18.20, P= 0.01) and Z + 2 (χ2 = 35.30, P < 0.01) allele in different groups. The combined OR of susceptibility to diabetic nephropathy in patients with Z-2 allele was 1.72 (95% CI 1.25-2.36, P < 0.01) and those of Z + 2 and Z + 6 were 0.73 (95% CI 0.47-1.12, P =0.15) and 0.66 (95%C10.45-0.98, P = 0.04) respectively. Conclusion The 5'-end dinucleotide repeat polymorphism of the aldose reductase gene was associated with the susceptibility of diabetic nephropathy in Chinese patients with type 2 diabetes mellitus. The Z -2 allele is a genetic risk factor for diabetic nephropathy, while the Z + 6 allele has protective function for kidney mierovessels.

A simple and sensitive method was developed for the detection of mercury ions with quartz crystal microbalance(QCM), based on the specific thymine(T)-Hg2+-T structure and gold nanoparticles. The gold nanoparticles were prepared by the citrate reduction method. In a self-assembled way, the particle surface was modified with the probe oligonucleotides which were partially replaced by 6-Mercaptohexan-1-ol to reduce the steric hindrance of hybridization. The sensitivity was optimized by the oligonucleotide with a strand length of 9bp and a T number of 7. The linear range was 5.0-100 nmol/L with a detection limit of 2.0 nmol/L. And Ca2+, Mg2+ and other metal ions had no significant interferences. This method was successfully applied for the detection of Hg2+in environmental water samples, with RSD less than 2.9% and recoveries of 97.3%-101.2%.

AIM: To investigate the changes of intrarenal endothelin system in the course of congestive heart failure. METHODS: A canine congestive heart failure model induced by rapid right ventricular pacing was used in the present study. Twenty-one mongrel dogs divided randomly into 3 groups: control, congestive heart failure 2 weeks(CHF2) and congestive heart failure 4 weeks (CHF4). The severity of heart failure was evaluated by means of hemodynamic measurement. The concentration of plasma endothelin was detected via RIA, and the expression of endothelin was detected by RT-PCR. RESULTS: The concentration of plasma endothelin in both of CHF2 and CHF4 elevated significantly. In CHF2, the expression of endothelin receptor B(ETB) in renal medulla increased significantly. And in CHF4, the expression of preproendothelin, endothelin receptor A(ETA) and ETB increased both in renal cortex and medulla. Furthermore, in cortex, the expression of ETA increased more significantly than ETB, while in medulla, ETB expressed much more than ETA. CONCLUSION: The changes of renal endothelin system expression plays a role in the regulation of water and electrolyte balance during the progress of congestive heart failure.

Objective To investigate the differences of protein and mRNA expression of matrix metalloproteinase 9 (MMP-9) in osteoclasts (OC) and osteoclast-like cells (OLC) obtained by mechanical and inducement methods. Methods Mechanical separation method was used to separate mature osteoclasts from long bones of SD rats aged one-day;and inducement culture method was applied to induce OLC by using RANKL (100 ng/mL) and M-CSF (100 ng/mL) . The protein expression of MMP-9 was measured by immunocytochemistry and mRNA expression of MMP-9 was assayed by in situ hybridization. Results The integral optical density (IOD) and average optical density (AOD) of positive cells in the visual field were higher in the 12-d group of inducement method as compared with the 3 d-group of mechanical method. Conclusions It is suggested that the protein and mRNA expression of MMP-9 in OLC obtained by 12 d inducement method is much high than in OC obtained by 3 d mechanical method. OLC obtained by inducement method can be applied in the study of osteoporosis.
