Objective To observe the therapeutic effect of Shenluo'an Decoction(SD) for the treatment of obese patients with early diabetic nephropathy and to explore the possible mechanism.Methods A total of 68 obese patients with early diabetic nephropathy were randomly assigned into control group and treatment group,34 cases in each group.Both groups were given conventional western medicine treatment including lifestyle regulation,dietary control,and medicine for lowering blood pressure,blood glucose and blood lipids.Additionally,the control group was given oral use of Irbesartan,and the treatment group was given oral use of SD combined with Irbesartan.Before and after treatment,we observed the traditional Chinese medical syndrome scores,body mass index(BMI),blood levels of cystatin C (Cys C),β2-microglobumin(β2-MG),homocysteine (Hcy) and fasting blood glucose (FBG),and urine parameters of urinary monocyte chemoattractant protein-1 / urinary creatinine (UMCP-1/UCR),urinary factor of regulated on activation in normal T cell expressed and secreted / urinary creatinine (URANTES/UCR),urinary albumin-to-creatinine ratio (UACR) and urinary albumin excretion ratio (UAER) before treatment and after treatment for 16 weeks.After treatment,the clinical efficacy and safety were also evaluated.Results (1) During the treatment,5 cases were dropped out,and a total of 63 cases (32 from the treatment group and 31 from the control group) completed the experiment.(2) The total effective rate of the treatment group(90.6％) was significantly higher than that of the control group(67.7％),the difference being significant(P ＜ 0.05).(3)BMI of the two groups after treatment was significantly lower than that before treatment (P ＜ 0.05).(4) After treatment,the traditional Chinese medical syndrome scores,blood parameters (Cys C,β2-MG,Hcy,FBG) and urine parameters (UMCP-1/UCR,URANTES/UCR,UACR,UAER) in the treatment group were decreased as compared with those before treatment and those in the control group after treatment(P ＜0.05).(5) A positive correlation was present among the parameters of UMCP-1/UCR,URANTES/UCR,UACR and UAER.(6) No abnormal changes took place in the blood and stool routine examination,hepatic function,or electrocardiography of the 63 cases.Conclusion SD combined with western medicine exerts certain therapeutic effect for obese patients with early diabetic nephropathy,and is effective on relieving clinical symptoms anddecreasing BMI,Cys C,β2-MG,UACR,UAER,UMCP-1 and URANTES.Its mechanism is probably related with the inhibition of chronic renal inflammation.

Objective To study blood type B antigen elimination with α-galactosidase in human liver tissue,and discuss the feasibility of blood type conversion in human liver.Methods The liver specimens from patients with blood type B in liver transplantation were collected,and an in vitro liver perfusion model was established.The in vitro livers were perfused with UW solution +/-α-galactosidase.The effect of enzyme in B antigen of human liver were analyzed by immunofluorescence.Results With UW solution containing α-galactosidase to perfuse the in vitro livers,immunohistochemistry showed the level of blood type B antigen in liver was significantly reduced after hypothermic perfusion and preservation.The B antigen level in 1 h perfusion was reduced to approximate 58％ of this figure prior to perfusion,in 2 h was 10％,and in 4 h was 4％.Among the different intervals,the blood group antigen levels showed significant differences (P ＜ 0.05).In the control group,the blood group antigen levels showed no obvious change on statistical analysis.Conclusions α-galactosidase was effective to clear blood type B antigen in isolated liver tissue.In the experimental group,Although the B antigen did not fall to a undetectable level,liver blood type conversion from B→O remains a promising potential which has been meaningful for related researches on blood type conversion of human organs.

The aim of this study was to propose an algorithm for three-dimensional projection onto convex sets (3D POCS) to achieve super resolution reconstruction of 3D lung computer tomography (CT) images, and to introduce multi-resolution mixed display mode to make 3D visualization of pulmonary nodules. Firstly, we built the low resolution 3D images which have spatial displacement in sub pixel level between each other and generate the reference image. Then, we mapped the low resolution images into the high resolution reference image using 3D motion estimation and revised the reference image based on the consistency constraint convex sets to reconstruct the 3D high resolution images iteratively. Finally, we displayed the different resolution images simultaneously. We then estimated the performance of provided method on 5 image sets and compared them with those of 3 interpolation reconstruction methods. The experiments showed that the performance of 3D POCS algorithm was better than that of 3 interpolation reconstruction methods in two aspects, i.e., subjective and objective aspects, and mixed display mode is suitable to the 3D visualization of high resolution of pulmonary nodules.
