Objective To compare effects of compound Xueshuantong capsule and benazepril on inflammatory cyto-kines in type 2 diabetic patients with early diabetic nephropathy (DN), and its therapeutic mechanism thereof. Methods Ninety-four patients with type 2 diabetes were divided into diabetes without albuminuria group (DM,n=24) and early DN group (DN,n=70). DN group was then divided into three subgroups:group A (n=24) treated by benazepril alone, group B (n=22) treated by compound Xueshuantong capsule and group C (n=24) treated by compound Xueshuantong capsule combined with benazepril for 3 months. Levels of fasting blood glucose, glycosylated hemoglobin, serum creatinine, blood urea nitro-gen, lipid profiles, fibrinogen and urinary albumin excretion rate (UAER) were examined before and after treatment. The se-rum levels of hypersensitive c-reactive protein (hs-CRP), interleukin-6 (IL-6) and tumor necrosis factor-α(TNF-α) were determined as well. Results The serum levels of hs-CRP, IL-6 and TNF-αwere significantly higher in DN group than those of DM group (P<0.01). After treatment, the serum levels of UAER, hs-CRP, IL-6 and TNF-αwere significantly re-duced in groups A, B and C compared with those before treatment (P<0.01), and which were decreased more significantly in group C. The levels of blood lipids and fibrinogen decreased obviously in group C compared with those of group A and B ( P<0.01). Conclusion Compound Xueshuantong capsule combined with benazepril not only can improve the blood fat and high coagulation state in patients, but also impossibly retard the development of early DN through decreasing serum concen-trations of hs-CRP, IL-6 and TNF-αand inhibiting inflammatory reaction.

OBJECTIVE:To optimize extraction technology of polysaccharides from Stemona tuberosa so as to increase the ex-traction rate and efficiency. METHODS:Anthrone-sulfuric acid method was used for detection. With water and alkaline water (NaOH solution)as the solvent respectively,the effects of decocting method,ultrasound method and microwave method on the ex-traction rate of crude polysaccharide were observed respectively. By carrying out single factor and orthogonal tests,with the extrac-tion rate of crude polysaccharide as the index,the effects of the amount of water,NaOH solution concentration,extraction tempera-ture and extraction time on the extraction of crude polysaccharide by alkaline water ultrasound method were observed to optimize the technology parameters,and verification test was conducted. RESULTS:The alkaline water ultrasound method is superior to oth-er extraction methods,where the optimal technology parameters were as follows as 0.3 mol/L NaOH aqueous solution 30 times as much as the amount of crud drug,ultrasonic processing for 70 min at 50 ℃. The verification tests showed that the average extrac-tion rate of crude polysaccharide was 25.76%(RSD=3.51%,n=6). CONCLUSIONS:The optimal alkaline water ultrasound method can better extract crude polysaccharide from S. tuberosa.

Ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF/MS) was developed to identify the absorbed parent components and metabolites in rat bile, plasma and urine after oral administration of Radix Paeoniae Alba extract (RPAE). A total of 65 compounds were detected in rat bile, plasma and urine samples, including 11 parent compounds and 54 metabolites. The results indicated that glucuronidation, hydroxylation and methylation were the major metabolic pathways of the components of RPAE. Furthermore, the results of this work demonstrated that UPLC-Q-TOF/MS combined with MetaboLynx? software and mass defect filtering (MDF) could provide unique high throughput capabilities for drug metabolism study, with excellent MS mass accuracy and enhanced MSE data acquisition. With the MSE technique, both precursor and fragment mass spectra can be simultaneously acquired by alternating between high and low collision energy during a single chromatographic run.
