Microwave-assisted extraction was optimized with response surface methodology for HPLC-fluorescence determination of puerarin and daidzein in Radix Puerariae thomsonii.The optimized extraction procedure was achieved by soaking the sample with 70% methanol（1∶15,v/v）for 30 min,and then microwave irradiation for 11 min at a power of 600 W.Coupling the extraction process with HPLC-fluorescence presented good recovery,satisfactory precision,and good linear relation.Compared with a method from the Chinese Pharmacopoeia,the proposed method enables higher extraction efficiency and more accurate analytical results.It can be of potential value in quality assessment of Radix Puerariae thomsonii medicinal materials.

On the base of element and metabolism balancing,the mathematic model of the human-like collagen expression phase with recombinant Escherichia coli BL21 was developed and the unknown parameters in the model were estimated with the method of nonlinear optimization.The model was in agreement with the growth kinetics and the metabolic kinetics,and the key calculated parameters of ?h,?p and mx were 1.173 mol?C-mol-1,293.814 mol?C-mol-1 and 17.878 mol?C-mol-1?h-1 respectively.This model could preferably predict the macroscopic reaction rates,and in the synthesis phase of human-like collagen,the specific growth rate should be controlled at 0.04 h-1 with controlling glucose feeding rate to gain the highest specific production rate of human-like collagen.

Objective To explore the feasibility of detecting death-associated protein(DAP) kinase promoter hypermethylation in the tumor tissues and plasma of patients with gastric adenocarcino- ma,and to evaluate the effect of DNA hypermethylation and autofluroscene spectrums of gastric juice on diagnosing gastric carcinoma.Methods Primary tumor tissues and plasma and gastric juice of 50 patients with gastric adenocarcinoma were collected.Gastric mucosa tissue,plasma and gastric juice of 20 patients with chronic superficial gastritis and 20 patients with benign gastric ulcer and 30 patients with chronic atrophic gastritis were collected as controls.After sodium-bisulfite treatment,extracted DNA was amplified for DAP kinase promoter hypermethylation by methylation-specific polymerase chain reac- tion.At the same time the gastric juice autofluroscene spectrums(the excitation wavelength was 288 nm,whereas the range of emission wavelength was 300-800 nm)were detected.Results Among the samples from 50 patients,p16 and DAP kinase hypermethylation were detected in 74.4% and 68.1% of tumor tissues,52.0% and 58.0% of plasma,58.6% and 76.0% of gastric juice.No hypermethylation was detected in samples of chronic superficial gastritis and serum of patients with gastric ulcer.Among the patients with gastric ulcer,p16 and DAP kinase hypermethylation were detected in 10.0% and 20.0% of tissues,5.0% and 15.0% of gastric juice.Among the samples from 30 patients with chronic atrophic gastritis,p16 and DAP kinase were detected in 10.0% and 23.3% of tissues,3.3% and 3.3% of sera,3.3% and 20.0% of gastric juice.The intensity of gastric juice autofluroscence spectrums of patients with gastric carcinoma was much higher than those in controls.The sensitivity of p16 and DAP kinase hypermethylation and autofluorescence spectrums together were 95.6% and 97.8% respectively.Con- clusions Promoter hypermethylation of the p16 and DAP kinase gene detected in plasma and gastric juice consists with that in primary tumor tissues of patients with gastric adenocarcinoma.The combination of DNA hypermethylation and autofluorescence spectrum has a good future in diagnosing gastric carcinoma.

Aim To research the protective effect and mechanisms of taurine on myocardial ischemia and reperfusion injury in rats. Methods Myocardial ischemia reperfusion models were established in SD rats. The effects of taurine on the size of myocardial infarction and the changes of activity of SOD , and the levels of MDA and NO in myocardium and plasma of rats with myocardial ischemia and reperfusion injury were observed. Results In rats with myocardial ischemia and reperfusion injury, the taurine could reduce the size of myocardial infarction (P
