Objective: To observe the therapeutic effects of Erchen decoction, Taohongsiwu decoction on CYP2E1 activity and microsome protein content in non-alcoholic fatty liver rats.Methods: Experimental animal model of non-alcoholic fatty liver rats were established , then treated with Erchen decoction, TaohongSiwu decoction.Microsome protein content and cyp2e1 activity are tested after treatment.Results: Microsome protein content of non-alcoholic fatty liver rats reduced and cyp2e1 activity increased. Compared with model group, in Erchen decoction group, the microsome protein content in hepatocyte increased significantly (P

Objective To study association of hepatitis B virus(HBV) precore (pre c)/basic core promoter(BCP) mutations with the genotype or the progression of liver disease. Methods The serum samples from 148 patients with HBV-relative diseases were collected, including 31 asymptomatic carriers, 32 with chronic hepatitis B (CHB), 40 with liver cirrhosis(LC) and 45 with hepatocellular carcinoma(HCC). The genes covering HBV pre c and BCP were amplified by nested polymerase chain reaction (nPCR). The PCR products were subjected to direct sequencing and the mutations in pre c 1896 and BCP 1762/1764 were determined by sequence analysis. HBV genotypes were also detected in the sera by restriction fragment length polymorphism based on S-gene PCR products. Results Of 148 serum samples of HBV, 128 were successfully genotyped and sequenced. There were 60 genotype B and 68 genotype C. The mutation in pre c (A1896) was significantly higher in genotype B than in genotype C (48.3% vs 29.34%, P

0.05). The sequence of five clones from one serum which was identified precore mutation by mPCR-RFLP were all A1896 mutant strains.Another serum identified mixture infection by mPCR-RFLP , one clone was A1896 mutant strain and four were G1896 wild strains.The results of mPCR-RFLP were verified by cloning.Conclusions Comparison with sequencing, the mPCR-RFLP method is simple,accurate and can be used in large-scale surveys and clinical research.

Objective To discuss the value of double stimulations and mild ovarian stimulation combined with Gn-RH-antagonist in patients with decreased ovarian reserve receiving in vitro fertilization and embryo transfer ( IVF-ET) . Methods 283 patients with decreased ovarian reserve who accepted in vitro fertilization were analyzed retro-spectively. 204 cases accepted double stimulations and 79 cases accepted mild ovarian stimulation combined with GnRH-antagonist, compared the outcomes of the two protocols. Results The average number of oocytes retrieved, viable embryos,high-quality embryos,consumption and duration of Gn,the serum progesterone( P) level on trigger day in the luteal phase were significantly higher than those in follicular phase. The serum luteinizing hormone( LH) level on trigger day was lower than that in follicular phase. The average number of oocytes retrieved,high-quality embryos,consumption and duration of gonadotropins( Gn) in mild stimulation combined with GnRH-antagonist were higher than those in follicular phase. LH level on trigger day was lower than those in follicular phase, while the numbers of viable embryos were similar. The consumption and duration of Gn in the luteal phase were higher than in stimulation combined with GnRH-antagonist, and there were no differences in the average number of oocytes re-trieved,viable embryos,high-quality embryos between the two groups. The cycle cancellation rate, available rate of oocytes and embryos were similar between the controlled ovarian hyperstimulation. The available rate of embryos in double stimulations was higher than mild ovarian stimulation combined with GnRH-antagonist,and the abortion rate was lower. Conclusion Controlled ovarian hyperstimulation during luteal phase can get better outcomes in patients with decreased ovarian reserve,double stimulations in the same menstrual cycle shortens the treatment time of IVF-ET,and it is a feasible method for patients with decreased ovarian reserve.

Objective According to the methods of the research on material basis of effectiveness in traditional Chinese drug decoction, compile the software for experimental design and data analysis. Methods With ".net" platform, we use Visual Basic 2005 and database knowledge to compile the software that can analyze the HPLC data of WATERS and AGILENT at the same time but do not depend on the original HPLC system. Results Successfully Compiling the software that can help to execute the research on material basis of effectiveness in Chinese medicine decoction and analyze the experimental data. Condusion With this software, we can clearly execute the methodology line and quickly analyze the data.

The quality of traditional Chinese medicine (TCM) is the concentrated reflection of its pharmaceutical value. We should pay attention to the quality of Chinese medicine because it is the core problem for the development of traditional Chinese medicine. Thequality of traditional Chinese medicine is the important connotation of Chinese medicine professional high-level personnel training. Thequality of Chinese medicine has become a priority of degree and diploma education in different levels of traditional Chinese medicine class specialized courses. The quality of Chinese medicine is an important content of traditional Chinese medicine curriculum system and includes the knowledge of Chinese traditional medicine quality factor, quality requirements, quality characteristics, quality management and quality evaluation, etc. This paper mainly discusses thequality of Chinese traditional medicine curriculum structure, textbook compilation and talent cultivation.

An efficient and repeatable approach in transforming the foxtail millet (Setaria italica ) using Agrobacterium LBA4404 horboring the plasmid pBI121 was established. Factors affecting transformation efficiency were investigated including the genotype, explants, the density of bacteria, the duration for inoculation and co-cultivation, and the concentration of acetosyringone in the medium. The maximum transformation conditions were: the callus induced from inflorescence was used as explant; the duration for inoculation with Agrobacterium at low cell density was 30-40 min; for the co-cultivation , the suitable concentration of acetosyringone in the medium was 0.1 mmol/L, and the duration was 2 days.

Druggability is crucial in pharmaceutical drug development as the source of drug research. Druggability research will face greater challenges because Chinese materia medica (CMM) is the multicomponent drug. In this paper, ideas and methods of study on CMM druggability were mainly proposed in combination with the chemical material basis of muticomponents of CMM.

Objective To select the components for quality control of Fructus Lycii based on the absorption of its extract. Methods To investigate metabolism of components of Fructus Lycii, everted rat gut sacs was carried out as well as the blood was taken from abdominal aorta,.and all samples were analysised by HPLC. Results There are twelve constituents absorbed between ileum and jejunum of rat , and four constituents were detected in the blood. Compound 2, 3, 4, 5, 6, 9, 10, 11 were absorbed in prototype forms in the intestine directly,and compound 1, 7, 8, 12 were new ones. On the other hand, four compositions(3, 7, 10, 13)could be absorbed into blood through analysis serum samples obtaining from aorta abdominalis of rats. Two of them (3, 10)could be absorbed directly by intestine, while(7)was absorbed into blood in new form . Conclusion Based on the intestinal absorption experiment and analysion of compsition in blood, components (3, 10, 13) can be the quality control ingredients of Fructus Lycii.
