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 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.

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.

Objective Using infrared spectroscopy to analyze three kinds of lignum Chinese medicine to provide a theoretical basis for the establishment of medicinal overall quality evaluation system. Methods Functional groups identification, Fourier Transform-infrared spectroscopy(FT-IR) and the second derivative infrared spectroscopy (SD-IR) could be applicable to analyze and identify the overall chemical composition of three kinds of lignum Chinese medicine. Results The main chemical components of Aquilariae Lignum Resinatum (ALR), Dalbergiae Odoriferae Lignum (DOL) and Sappan Lignum (SL) were cellulose, lignin and aromatics. The main chemical compositions of Sappan Lignum (SL) were cellulose, lignin and aromatics. The differences in FT-IR and SD-IR of DOL and SL indicated that they had different aromatic compounds. Conclusion Infrared spectroscopy can be used as a simple and accurate quality control method of three kinds of lignum Chinese medicine.
