Objective To screen and identify the novel genes from the adult worm cDNA library of Schistosoma japonicum by the expressed sequence tags (EST) strategy.Methods The cDNA clones were selected randomly and the ESTs were obtained.The novel gene was searched for homologue identity with NCBI blast programmer.The homologue of the two sequences with a high identity was compared at amino acid and nucleotide level with the BLAST programmer,and the analysis of protein was carried out with the pcgene software. Results There was a novel gene of Schistosoma japonicum which included 1 677 bp coding for 424 amino acid residues, and it was given the accession number of sequence in Genbank(AY336497).The cDNA sequence was homologous to the known ornithine aminotransferase gene of Xenopus laevis. The identity of amino acid sequence was 66%. The academic pI was 8.52, and the antigen determinant was probably from 795 to 846 on the cDNA sequence. Conclusion EST strategy is an effective measure to discover new genes of Schistosoma japonicum. The novel gene is homologous to the ornithine aminotransferase gene of Xenopus laevis.This study is helpful to further sequential and functional search of the gene.[

Objective To explore the relationship between age and refractive predictability of excimer laser in situ keratomileusis (LASIK)for the correction of myopia.Design Retrospective case series.Participants 362 patients(703 eyes)who had performed LASIK.Methods According to the age,patients were divided into four groups(≤30y,31~34y,35~39y and≥40y).Their preoperative and postoperative refractive powers examined with automatic refactor as well as manifest optometry were analysed and followed up from 6 months to 2 years.According to pre-operative refractive power,patietns were divided into low and moderate myopia group(≤-6.00D), high myopia group(-6.25~-12.00D)and super-high myopia group(≥-12.25D).The eyes with refractive power at post-operative 2 years≥-1.00D were regressive eyes.Main Outcome Measures Refractive error before surgery,intended residual refractive power and 3,6, 12, 24 months post-operative refractive powers.Results There were no significant differences between intended residual refractive powers and refractive powers at post-operative 6 month in 3 groups(

Hyoscyamine 6 beta-hydroxylase (H6H) is the last rate-limiting enzyme directly catalyzing the formation of scopolamine in tropane alkaloids (TAs) biosynthesis pathway. It is the primary target gene in the genetic modification of TAs metabolic pathway. Full-length cDNA and gDNA sequences of a novel H6H gene were cloned from Datura arborea (DaH6H, GenBank accession numbers for cDNA and gDNA are KR006981 and KR006983, respectively). Nucleotide sequence analysis reveals an open reading frame of 1375 bp encoding 347 amino acids in the cDNA of DaH6H, while the gDNA of DaH6H contains four exons and three introns, with the highest similarity to the gDNA of H6H from D. stramonium. DaH6H also exhibited the most identity of 90.5% with DsH6H in amino acids and harbored conserved 2-oxoglutarate binding motif and two iron binding motifs. The expression level of DaH6H was highest in the mature leaf, followed by the secondary root, and with no expression in the primary root based on qPCR analysis. Its expression was inhibited by MeJA. DaH6H was expressed in E. coli and a 39 kD recombinant protein was detected in SDS-PAGE. Comparison of the contents of scopolamine and hyoscyamine in various TAs-producing plants revealed that D. arborea was one of the rare scopolamine predominant plants. Cloning of DaH6H gene will allow more research in the molecular regulatory mechanism of TAs biosynthesis in distinct plants and provide a new candidate gene for scopolamine metabolic engineering.

Objective Construct the reasonably effective performance assessment mode of clinical departments,which is suitable for the continuous development of modern hospital.Method Use of balanced scorecard (BSC) principle,using the analytic hierarchy process (AHP) and Rank sum ratio method (RSR)to establish a performance assessment system. Results Constructed the performance assessment mode of clinical departments,which can be dynamically adjusted based on management objectives strategy.The mode takes the BSC as the baseline,the strategy of hospital development as the guide,performance assessment index system as the key element. Conclusion The performance assessment mode of clinical departments,base on BSC,achieve the strategic performance management,and is conducive to the hospital for continuous improvement of medical care quality,in line with the long-term strategic needs of the hospital.
