The effectiveness and efficiency of university educational management would have a direct impact on universities' teaching performance.Moreover,it is important to undertake a further reformation for the educational management system of university and college and establish such a standardized,high efficient educational management system.Since they would be the milestones that improve universities'teaching performance constantly and ensure there is a persistent evolution in universities as well.

Ubiquitin-proteasome pathway is one of the primary pathway in intracellular protein degrada-tion,therefore the ubiquitin conjugating enzyme D3(UbE2D3)which involved in the ubiquitin mineralization process can affect the biological effects accordingly to affect some protein and nucleic acid content and activity. The function that participate in modification and degradation of some cancer factors is vital in tumor cells,and followed by tumor biological behavior changing. Researches show that UbE2D3 correlates with human telomer-ase reverse transcriptase( hTERT),radiation sensitivity,aggressive,etc in breast cancer.

AIM: To study the effect of double gene transduction mediated by lentiviral vectors on the characteristics of human embryonic stem cells (hESCs). METHODS: Using the backbone from inducibal dual and excisable transgene vector (iDuet101) , lentiviral vectors overexpressing cytotoxic T lymphocyte - associated molecule - 4 immuno-globulin (iDuet101 - CTLA4Ig) , indoleamine 2, 3 dioxygenase (iDuet101 - IDO) , and ubiquitin - C promoter - lueifer-ase - ires - puromycin ( ULIP) were constructed and packaged according to the standard recombinant techniques. Human embryonic stem cells (hESCs) were first transduced with iDuet101, iDuet101 - CTLA4Ig or iDuet101 - IDO, then, after the selection, were transduced again with ULIP. The expression and function of the exogenous genes were detected. Immu-nohistochemistry, RT - PCR and flow cytometry were applied for detection of embryoid bodies ( EB) formation in vitro and in vivo teratoma formation. RESULTS: Double - transduced hESCs showed typical shape of cell clones and positive staining of tumor rejection antigen -1 - 60 ( Tra -1 - 60 ) and octomer transcription factor - 4 ( OCT - 4 ). The formation of EB was observed, in which a - fetoprotein (AFP), paired box gene 6 ( Pax6) and Musashi 1 ( MSI1) were positively expressed. The cells formed teratomas, and the luciferase signals existed until 28 days after xeno - transplantation. CONCLUSION : Double transduction of non - transcriptional factors mediated by lentiviral vectors does not affect the cell growth rate and their differentiation ability.

Objective:To optimize the processing technology of prepared Morinda officinalis based on nystose content. Methods:Orthogonal experiments and the nystose determination method in Chinese Pharmacopoeia (2010 edition) were used to optimize the pro-cessing technology. A Welch AQ-C18(250 mm ×4.6 mm,5 μm)chromatographic column was applied with methanol-water(3∶97)as the mobile phase, the column temperature was at 25℃, the flow rate was 0. 8 ml·min-1 , the injection volume was 10μl, and the drift tube temperature was at 40℃ with low temperature atomization. Results:The linearity of nystose was good within the range of 0. 214 8-0. 644 4 mg·ml-1 and the recovery was 99. 5%(RSD=3. 5%,n=6). Conclusion: On the basis of nystose content determination, the optimal processing technology of prepared Morinda officinalis is as follows:liquorice of 4%, stir fry time of 15min and the boiling pot temperature of 200℃.

Objective To study the function of the X\|zone cells in the 5 days old male mouse adrenal gland and the relationship between the function and the sexual differentiation. Methods The technique of in situ RP\|PCR was used to detect the expression of type Ⅰ and Ⅲ 17? HSD mRNA. Results In the cells of X\|zone which located in the interface between adrenal crotex and medulla, there were expressions of type Ⅰ and Ⅲ 17? HSD.Conclusion\ The X\|zone cells of adrenal gland in immature mouse could synthesize androgen, enhanced the male sexual differentiation together with the androgen synthesized from the testis.\;[

Objective To provide a scientific reference for the choice of antimicrobial drugs by analyzing the distributions and the antimicrobial resistances of Carbapenem‐resistant Acinetobacter baumannii (CR‐AB) and methicillin‐resistant Staphylococcus au‐reus (MRSA) in the Northern Jiangsu People′s Hospital .Methods All the CR‐AB and the MRSA isolated from hospitalized pa‐tients from January 2011 to March 2014 were collected and analyzed .Use the disk diffusion method for antimicrobial resistance tes‐ting .Results A total of 170 CR‐AB strains and 168 MRSA strains were isolated .CR‐AB mainly distributed in the ICU ,which ac‐counting for 61 .17% (104/170) .MRSA mainly isolated in neurosurgery ,about 27 .98% (47/168) .67 .06% of CR‐AB strains and 54 .17% of MRSA strains were from Sputum specimens .The antimicrobial resistance rate of CR‐AB to most antimicrobial drugs were reached 50 .00% ,the resistance rates to cefoperazone/sulbactam (27 .65% ) ,minocycline (21 .18% ) ,amikacin (19 .41% ) and tobramycin (12 .35% ) were all less than 30 .00% ,the strain that resistant to polymyxin was not found .The sensitivity rates of MR‐SA to linezolid ,vancomycin ,and tigecycline were 100 .00% ,and the resistance rates to nitrofurantoin and kuinuputing/ dalfopristin were low (less than 2 .00% ) .Conclusion The antimicrobial resistances of CR‐AB and MRSA are serious .In order to control effec‐tively the spreading of CR‐AB ,MRSA and other multi‐drug resistant bacteria ,it′s necessary for us to strengthen the management of key departments ,and select antimicrobial drugs based on the results of drug susceptibility testing .

Objective To observe blood glucose values and serum insulin levels at different times after acupoint injection of insulin with PVP as a sustained release agent and analyze the correlation between them in SD Rats.Methods One hundred and forty-four male SD rats were randomized into groups A (acupoint injection of insulin alone), B (acupoint injection of sustained-release insulin) and C (control). At one hour after every group received an oral gavage of 40% glucose solution (2.2 g/kg), groups A and B were given point Zusanli injection and group C was not treated. In the three groups of rats, blood glucose values and serum insulin levels were measured at six time points: 0.5, 3, 6, 8, 10 and 24 hours after acupoint injection (in group C at the corresponding time points). In every group, the reaction of Point Zusanli region to the stimulation was observed by optical microscopy in at three time points: 3, 10 and 24 hours after acupoint injection.Results The glucose-lowering rate reached its peak at 3 hours after acupoint injection and then declined in groups A and B. The hypoglycemic effect tended to be stable at 6 hours after acupoint injection in group A and at 10 hours after acupoint injection in group B. The hypoglycemic effect was better in group B than in group A at 6 and 8 hours after acupoint injection (P<0.01). In group A, serum insulin reached its peak at 3 hours and tended to be stable at 6 hours after acupoint injection (P<0.05). Serum insulin levels were significantly lower in group B than in group A at four time pints: 0.5, 3, 6 and 8 hours after acupoint injection (P<0.05). An analysis of the correlation between rat serum insulin levels and the glucose-lowering rate showed a significant positive correlation in group A (P<0.01) and a low positive correlation in group B (P<0.05). In groups A and B of rats, clear stripes and complete structure of muscle fibers were seen with no obvious degeneration, necrosis and inflammatory reaction around point Zusanli at three time points: 3, 8 and 24 hours after acupoint injection; there were no obvious pathological changes compared with group C.Conclusions PVP as a sustained release agent can slow down the absorption rate of insulin in rat point Zusanli region. Meanwhile, it prolongs the continuous time of the hypoglycemic effect of insulin. There is a low correlation between serum insulin levels and the hypoglycemic effect, suggesting that acupoint injection with a sustained release agent can prolong the effect of acupoint injection of medicine.
