The recombinant plasmid pPIC-gpd-bgl-hyg was constructed, which contained GPD2 promotor and terminator from industrial yeasts Saccharomyces cerevisiae, ?-glucosidase gene (BGL1) from Sac-charomycopsis fibuligera and hyg from hygromycin as the selected marker. With the yeast’s high efficiency of homologous integrated, the BGL1 gene was successfully integrated into industrial yeasts S. cerevisiae. The recombined yeast could grow on the cultures with the cellobiose as a sole carbon source, and the ?-glucosidase activity achieved 0.764 U/mL after 48 hours’ cultivation. In the experiments of VHG ethanol fermentation, the cellobiose concentration in broth of recombined yeast was 80% lower than that of indus-trial yeast.

Objective To investigate the role of mutation of insulin receptor(IR) gene on the development of ischemic cerebral vascular disease.Methods The base variations at exon 17 and 20 of IR gene, by means of PCR SSCP were determined in the 68 cases of atherothrombotic cerebral infarction (ACI), 81 cases of lacunar infarction (LI) and 62 healthy controls.Results There were two alleles of T and C at exon 17 of IR gene. The prevalence of mutant of T allele in ACI patients was more common than that in the controls. The blood pressure and the parameters of blood sugar,lipid metabolism in the patients with mutant were higher than those in the controls with wild type gene. The correlative analysis showed the polymorphism of IR gene was not related statistically to the blood pressure. No base variation at exon 20 was found in the study.Conclusion By promoting the development of atherosclerosis,the mutation at exon 17 of IR gene may participate in the occurrence of ischemic stroke.

An overall improvement of teaching quality is the core task of the reform and the development of higher education. Based on the analysis of the main factors of affecting the teaching quality in universities and combined with the implementation of “views on improving the overall qual-ity of higher education”by the Education Ministry, countermeasures for improving the teaching quality of undergraduates have been proposed such as increasing higher education funds investment to im-prove the condition of running a school, paying attention to the construction of teaching management staff to improve the level of teaching management, establishing Teacher Development Research Center to consolidate the fundamental position of undergraduate teaching , utilizing the high-quality social resources to implement the collaborative education innovation, and improving the personnel training system to strengthen the teaching quality standard .

Objective To find out the common allergen of abnormal rhinitis in Shenzhen.Methods To take in process of allergopharma skin prick test(ASPT) for 855 dubitable patients with abnormal rhinitis to determine the main allergen.Results 578 patients in the 855 dubitable patients of abnormal rhinitis were positive(67.6%).These allergens were mostly inhalant.Among the 578 patients,51 cases were caused by single allergen;527 cases caused by more than two kinds of allergens;520 cases(90%) were positive in dermatophagoides pteronyssinus;488(84.4%) cases were positive in dermatophagoides farinae.Conclusion According to the common allergen of abnormal rhinitis in Shenzhen,and education to patients underwent ASPT can improve the accuracy of the test,lighten the symptom of abnormal rhinitis and raise the cure rate.

Objective To study the assessment value of enhanced CT for axillary lymph node in breast cancer.Methods 71 patients meeting the inclusion criteria in our hospital were reviewed.They had level Ⅲ lymph nodes pathologically confirmed for almost 2 years.CT scan by a 64-detector row scanner were performed from the lower edge of breast to neck.CT images were analyzed from these aspects:with or without lymph node enlargement; the size and shape of the lymph nodes; lymph node with or without enhancement.Through the determination of CT net increase value,the metastasizing lymph node signs were explored.Diagnostic index of axillary lymph nodes imaged by breast sonography and enhanced CT were calculated separately.The size of level Ⅲ lymph node and CT net increase value were statistically analyzed.The correlation of metastasizing level Ⅲ lymph node and tumor location was analyzed.Results The accuracy,sensitivity,specificity,and positive predictive value of diagnosed axillary lymph node was 70.4％,85.7％,64.0％,and 50.0％ by three-dimensional ultrasound and 88.7％,90.6％,83.3％,and 94.1％ by enhanced CT.The accuracy,sensitivity,specificity,and positive predictive value of diagnosed level Ⅲ lymph node was 95.8％,90.5％,98.0％,and 95.0％ by enhanced CT.The maximal diameter of level Ⅲ lymph node was ＞ (8.7 ± 1.3) mm and the short diameter was ＞ (5.3 ±0.5) mm.CT net increase value was ＞ (50.0 ±9.0) HU.The shape of lymph nodes was mainly round or oval solid.Conclusions The diagnosis rate for level Ⅲ lymph node is obviously higher by enhanced CT than by three-dimensional ultrasound.There is no obvious correlation between level Ⅲ lymph node and tumor location.

This research uses six Agrobacterium rhizogenes R1601, R15384, R1000, A4, R1025 and R1 to infect silymarin explants to induce hairy roots and silibin. All of the six A. rhizogenes can induce Silybum marianum to generate hairy roots and the A. rhizogene A4 shows comparatively high infection on the plant. This research determines the condition to induce silymarin hairy roots by the factors of infection time, pre-culturing, co-culturing and pH value. The fact that MS liquid medium fits the proliferation of silymarin hairy roots is determined. Through PCR molecular identification, it can be seen that the DNA plasmids in the A. rhizogenes are successfully integrated into the genome of transformed roots. Using liquid chromatography, it is determined that the silibin content in silymarin hairy roots is 2.5 times that in the plant In this research, the silymarin hairy roots culturing system is established, which lays a foundation for the study of culturing silymarin hairy roots and producing silibin.

A total of 35 patients with hallus valgus (56 feet) received treatment at the Department of Orthopedics, the Sixth People's Hospital, Shanghai Jiao Tong University between January 2004 and June 2005 and were recruited into this study. These patients underwent osteotomy of proximal first metatarsal and internal fixation with poly (L-lactic acid) (PLLA) absorbable pins. All patients were followed up for 4-22 months. Excellent outcomes were found in 27 patients (44 feet) and good results in 8 patients (12 feet). The mean healing time of surgical region was 6 weeks, nonunion or delayed union was not found. There were 3 cases suffering from complications post surgery. Two of them presented with peripheral wound red swelling, considering as a result of extraneous material-caused aseptic inflammatory reaction. This phenomenon would be regressed 2-4 weeks after hydropathic compress of ethanol gauzes and timely renewal of dressings. There was 1 case who suffered from protrution of absorbable pin 1 week after fixation and received reposition and plaster fixation. Bone displacement and nonunion were not found. This complication maybe results from excessively large bone pore due to shaking of electrodrill, which leads to loosening of absorbable pins.
