Methods: A total of 180 patients with diabetic nephropathy admitted to Nephrology Department of our hospital were randomly divided into control group and observation group, 90 cases in each group. The patients in the control group were given conventional treatment, such as antihypertensive drugs, diet and blood glucose control, and the patients in the observation group were given Compound α-Ketoacid Tablets on the basis of the control group. Renal function, renal fibrosis index and oxidative stress levels were compared between the two groups before and after treatment. Results: After treatment, the levels of serum ALB, BUN, Cr, Hcy, VEGF and MDA in two groups were significantly decreased than those before the treatment, and the levels of ALB, Hcy, VEGF and MDA in the observation group were significantly lower than those in the control group, the difference was statistically significant. After treatment, the levels of serum GFR, HGF, T-AOC and SOD in two groups were significantly increased than that before the treatment, and the levels of HGF, T-AOC and SOD in the serum of the observation group were significantly higher than that in the control group, the difference was significant. Conclusion:The Compound α-Ketoacid Tablets has good effect in the treatment of diabetic nephropathy. It can effectively improve the state of renal fibrosis and reduce the oxidative stress reaction of the patients, so as to achieve the protection of the kidney.展开更多

For the DC-DC converter for flash memory IPs using a dual voltage of VDD (=1.5V±0.15V)/VRD (=3.1V±0.1V), a scheme of using VRD (Read Voltage) instead of VDD is proposed to reduce the pumping stages and pumping capacitances of its charge pump circuit. VRD (=3.1V±0.1V) is a regulated voltage by a voltage regulator with an external voltage of 5V, which is used as the WL activation voltage in the read mode and an input voltage of the charge pump. The designed DC-DC converter outputs positive voltages of VP6V (=6V), VP8V (=8V) and VP9V(=9V);and a negative voltage of? VM8V (=-8V) in the write mode.展开更多
