The process of protein synthesis is terminated by one of the three stop codons which are recognized by classⅠ polypeptide release factors.Subsequently, it could promote the hydrolysis of the ester bond of peptidy-tRNA, resulting in release of the nascent polypeptide.Recent results from cryoelectron microscopy, crystallography, NMR, molecular dynamic and biochemical experiments have shed considerable light on the function and structure of the classⅠ release factors.The progress in these aspects were summarized.

The practical teaching system for information management and information system science in higher medical institutions was constructed with job skill training as its target by intruding the concept of competence-based education model into it in order to improve the practical performance of undergraduates majoring in informa-tion management and information system science. The system was designed by taking into consideration the teaching contents, teaching methods and teaching practice, and implemented in the undergraduates of Chengdu Medical College, and the implementation experiences were summarized.

Objective To systematically assess the efficacy and safety of electroacupuncture for trigeminal neuralgia. Method Randomized controlled trials of a electroacupuncture treatment for trigeminal neuralgia were sought by a computer search of CNKI,Wan Fang Data,VIP,CBM,PubMed,EMbas and The Cochrane Library.The retrieval time limit was from March 1996 to March 2016. Two reviewers sifted the literature and extracted data independently according to the inclusion and exclusion criteria andthen assessed the riskofbias of the included literatureusing the Cochrane risk of bias assessment tool.Ameta-analysis was made using RevMan 5.3.Result Finally, 12 articles were included with atotal of 847 subjects.The results ofmeta-analysis showed that the total efficacy rate was higher in the electroacupuncture group than in the control group [OR=4.04,95%CI(2.67, 6.13),P<0.00001].There were no statistically significant differences in the VAS score [MD=﹣0.06,95%CI(﹣0.59, 0.47),P=0.82] and the recurrence rate [OR=0.64,95%CI(0.05,7.45),P=0.54] between the electroacupuncture and control groups.Conclusion The currentlimited evidenceshows that the total efficacy rate fortrigeminal neuralgiais higher in the electroacupuncture group than in the control group.There are no statistically significant differences in the VAS score and the recurrence rate of trigeminal neuralgia between the electroacupuncture and control groups of patients.But the conclusions need more high-qualitytrials for validation owing to the limitation of the sample size of the included studies.

0.05).There was a positive correlation between the tempo of the engraftment and the progressive increase of the doses of MNC in the range of (3~5.99)?108/kg,but which was not found in the range of 6?108/kg.Conclusion These results indicate that MNC taken as an index for the measurement of the hematopoietic stem cell/progenitor content can reliably predict hematopoietic reconstitution after both HLA-matched and-mismatched sibling donor peripheral blood stem cell transplantation,with the rate and tempo of engraftment comparable with that in CD34+ cell group,and however,the target dose was reached with one apheresis in all 83 donors in MNC group(100%),as compared with 14 donors in CD34+ cell group(37.84%),suggesting that MNC may replace CD34+ cell as an independent index for the assessment of the stem cell/progenitor content in clinical practice.

Objective To study the effect of a diterpenoid 5F (ent-11?-hydroxy-15-oxo-kaur-16-en-19-oic acid) isolated from Pteris semipinnata on the expressions of NF-?B (P65), Smad3 protein and NF-?B (P65), ETS-1 mRNA, and to investigate the antitumor mechanisms of 5F. Methods MTT assay was used to examine the effect of 5F on proliferation of HO-8910PM cells. The expressions levels of NF-?B (P65) and Smad3 proteins were assessed by Western blot analysis. RT-PCR assay was used to assess the expression levels of NF-?B (P65) and ETS-1 mRNA. Results The proliferation of HO-8910PM cells can be inhibited by 5F in a dose-dependent manner. The expression levels of NF-?B (P65) and Smad3 proteins decreased obviously in HO-8910PM cells after treatment with 25—100 ?mol/L 5F for 24 h, and the effects appeared in a dose-dependent manner. 5F down-regulated significantly the expression of NF-?B (P65) mRNA, down-regulated gently the expression of ETS-1 mRNA. Conclusion The antitumor activity of 5F is involved in the expression of NF-?B (P65), Smad3 protein and NF-?B (P65), ETS-1 mRNA.

Objective To evaluate the value of contrast-enhanced CT in diagnosis of mesenteric fibromatosis (MF).Methods CT images of 6 patients with pathologically proved mesenteric fibromatosis were retrospectively analyzed.The imaging characteristics analysis in-cluded the number,size,density of the lesion,the degree and quality of enhancement,as well as the relationship with the surrounding tissues.Results Singular lesion located in the mesentery was found in all the 6 patients (100%).The size of all cases ranges from 2.0 cm to 8.5 cm and the mean diameter was 6.5 cm.CT scan showed 5 tumors were homogeneous (83.3%),while one tumor had mixed den-sity (1 6.7%).On contrast-enhanced CT images,5 cases showed mild enhancement (83.3%),while 1 case showed moderate en-hancement (1 6.7%).And 4 cases appeared as heterogeneous enhancement (66.7%).4 cases of lesions infiltrated the surrounding tissue(66.7%)and the peripheral intestines were compressed in 2 cases(33.3%).5 masses were surrounded by mesenteric vessels (83.3%).Conclusion MF has certain CT manifestations,especially when mesenteric vascular surrounded the lesion.CT can provide important information for the diagnosis of this disease.

Objective To investigate the antibacterial activity of combined antimicrobial agents for imipenem-resistant Acinetobacter baumannii in vitro,so as to provide evidence for guiding clinical practice.Methods Twenty-seven isolates of irnipenem resistant Acinetobacter baumannii were collected from March,2007 to February.2008.The minimal inhibitory concentrations(MIC)of the isolates against eleven frequently used antibiotics were determined by E test and agar dilution.Combined drug sensitivity testing was performed by broth checkerboard titration assay.Synergism between minocycline and cefoperazone-sulbaetam was analyzed by time-killing curve.Results The results from checkerboard titration assay and time-kill studies showed that the synergy rates between minocycline and cefperazone-sulbactam,minocycline and amikacin,minocycline and ciprofloxacin were 74.1%,28.0%and 48.1%,respectively.The synergy rates between amikacin and cefoperazone-sulbactam,anaikacin and ciprofloxaein were 23.1%and 37.0%,respectively.The synergy rate between cefoperazone-sulbactam and ciprofloxacin was 7.1%.With combination therapy.both MICs of cefoperazone-sulbactam and MIC of minocyeline decreased to lower than breakpoints.According to time-killing curve,the synergy rate between cefoperazone-sulbactam and minocycline was 100%.Conclusion Minocycline and cefoperazone-sulbaetam can be used for treating infections caused by multidrug resistant Acinetobacter baumannii.
