Objective To observe influence of Benazepril combined with Jinshuibao capsules on urine protein and Ccr in patients hypertensive renal disease. Methods 47 hypertensive renal disease patients were randomly divided into control group and combine group. Patients in control group were treated with Benazepril, while patients in combined group were treated Jinshuibao plus Benazepril. Clinic index change after treatment for 9 weeks was observed, and calculation endogenous creatinine clearance rate was calculated. Results After treatment for 9 weeks urine protein in 24 hours of two groups were both lower than before( t1 = 1. 9997 ,t2 = 3.3088 ,P ＜ 0. 05 or P ＜ 0. 01 ),while the endogenous creatinine clearance rate were both higher than before ( t1 = 1. 3990, t2 = 1. 4442, P ＞ 0. 05 ), and the press were all in improvment ( t1 = 2.0047, t2 = 2.4557, t3 = 2.0426, t4 = 2.4026, P ＜ 0. 05 ); urine protein in 24 hours of combine group was lower than control group( t = 2.0015,P ＜ 0. 05) Conclusion Benazepril plus Jinshuibao capsules could obviously abate urine protein on patients with hypertensive disease and hypertensive renal disease

5R-5-hydroxytriptolide (LLDT-8) is a new drug candidate which is in clinical trial treating rheumatoid arthritis. Polymorph screening of the compound was carried out in this study. Polymorph of LLDT-8 was prepared by evaporative crystallization and antisolvent crystallization methods and was characterized by powder X-ray diffraction (p-XRD), infrared spectrometry (IR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TG). It was found that p-XRD patterns, DSC curves, TG curves and IR spectra of the LLDT-8 samples prepared by the above recrystallization methods were all consistent. The 20 of main peaks in the p-XRD patterns appeared at 7.58 degrees, 8.14 degrees, 8.66 degrees, 15.46 degrees, 16.46 degrees, 29.54 degrees, 31.16 degrees and 38.26 degrees, while the infrared absorption peaks appeared at 3 471.3, 2 962.2, 2 887.0, 1 762.6, 1 677.8, 1 432.9, 1 365.4, 1 247.7, 1 080.0, 1 031.7 and 877.5 cm(-1). LLDT-8 was decomposed at 271.2 degrees C based on the determination from DSC and TG. It was showed in single crystal X-ray diffraction study that LLDT-8 crystal was monoclinic with the space group being P2 (1). The cell parameters were found to be: a = 11.460 1 (11), b = 6.320 5 (6), c = 13.028 1 (12), alpha = 90.00, beta = 115.557 (2) and gamma = 90.00. The crystal was a hydrogen-bonded dimmer. The slurry experiments, which were further conducted in solvents with different polarities, confirmed the stability of solid state of LLDT-8 based on the p-XRD determination. The polymorph of LLDT-8 made assurance of its efficacy consistence during its clinical trials.

AIM:To elucidate the molecular mechanisms of lipoic acid (LA) on redox regulation and digestive function in intestine of C57BL/6 mice fed high fat diet (HFD).METHODS:C57BL/6 mice were randomly assigned to one of three groups (n=8). The control group consumed an ordinary diet. The other two experimental groups were fed with a high fat diet,high fat plus 0.1% LA. After 6 weeks,the activities of digestive enzymes were examined. In order to evaluate the antioxidant status of the mice,superoxide dismutase (SOD),malondialdehyde (MDA),total antioxidant capacity (TAC) and reactive oxygen species (ROS) in intestinal homogenate were measured. To investigate the molecular mechanisms underlying the effects of LA,the gene expression profiles in intestine were examined using the GeneChip microarray system.RESULTS:A depressed antioxidant defense system,accompanied by digestive and absorptive function impairment,was observed in HFD-fed mice. These changes were partially restored in the LA-treated group. DNA microarray analysis of intestine showed that LA ingestion up-regulated the expression of genes related to free-radical scavenger enzymes,digestive enzymes and transporters.CONCLUSION:Treatment with LA improves redox homeostasis and the function of intestine in mice fed HFD. The mechanism may involve preventing oxidative stress by scavenging ROS directly and increasing those of free-radical scavenger enzymes gene expression indirectly.

Objective To explore the influence of high fat diet on the intestinal gene expression profile in C57BL/6 mice. Method C57BL/6 mice were randomly assigned to two groups (n=8). The control group consumed an ordinary diet. The experimental group was fed with a high fat diet. All mice were sacrificed at the end of 6 w and the intestinal gene expressions were detected by oligonucleotide microarray analysis with Affymetrix GeneChip Mouse U430A consisting of 13 097 genes. Results Among the 13 097 genes obtained from gene expression profile analysis, there were 88 and 179 genes up -and down-regulated respectively, in mice fed with high fat diet compared with the control. The differentially expressed genes were mainly related to free radical oxidative stress, DNA repair, induction of apoptosis, transport, signal transduction and inflammation immune response. Conclusion High fat diet may widely modulate the expression of many genes in the intestine in mice.
