Objective To study the effect of TFF_2 gene theragy on the healing of experimental gastric ulcer in rats and its mechanism.Methods From Jun.10,2005 to Mar.15,2006.48 Wistar rats were randomly divided into two groups:24 in therapy group,24 in control group.pcDNA3.1-TFF_2 100?g was used in each rat in therapy group,and the same volume of pcDNA 3.1 was used in control group.Each rat was injected under serous membrane of the gastric wall after making model.The rats were executed separately after 3、7、14 days.Results Ulcer index was 9.7?2.9 mm2 in therapy group and was 17.7?3.1 mm2 in control group on the 14th day.There was significant difference between the two groups.The average amount of mucous glycoprotein was 83.35?4.54 mg/g in the therapy group and 70.36?4.22 mg/g in the control group.There was no significant change in the secretion of acid between the two groups.Conclusion TFF_2 gene therapy can promote the healing of experimental gastric ulcer in rats.Its mechanisms may include increasing mucous glycoprotein of the gastric wall without suppressing gastric acid secretion.

Abstact:Objective To explore the effect of different arrangement of hollow screws in treatment of femoral neck fracture.Methods The clinical data of 160 cases with femoral neck fracture from March 2010 to May 2014 in our hospital were collected.They were randomly di-vided into triangle group and inverted triangle group according to arrangement of hollow screws.The operation time,intraoperative blood loss, fluoroscopy frequency in operation,length of stay,time of fracture healing,postoperative complications,Harris score and functional recovery of two groups were recorded and compared.Results The operation time and intraoperative blood loss in inverted triangle group were lower than those in triangle group,the difference was significant(P <0.05).The shortening rate of inverted triangle group and triangle group were 10%and 26.3% respectively.The shortening rate of inverted triangle group was lower than those of triangle group,the difference was significant (P <0.05).For the fluoroscopy frequency in operation,average hospitalization time,fracture healing time,rate of nonunion and femoral head necrosis,Harris score and functional recovery,there was no statistical significance between two groups(P >0.05).Conclusion Inverted tri-angle hollow screws treating femoral neck fracture makes surgery operation easier,operative time shorter and blood loss smaller.

Objective To assemble fusion gene of c-myc tagged human trefoil factor family 2(hTFF2)(in vitro) and construct a cloning vector of this fusion gene.Methods Based on amino acid sequence of hTFF2 and codon of lactococcus lactis,cDNA of htff2 sequence was designed and extended at their 5' ends with a sequence encoding the c-myc tag;and the sequence of fusion gene c-myc-htff2 was designed.According to restriction enzyme sites of pBluescript Ⅱ sk(+),the SalⅠ and BamHⅠ were arranged at 5′ and 3′ ends of the fusion gene respectively.Instructed by DNAWORKS program,the fusion gene sequence of c-myc-htff2 was designed as 14 oligonucleotides that overlapped each other.The target gene fragment of cmyc-htff2 fusion gene was obtained by the means of polymerase chain reaction(PCR) based gene assembly.Then,the c-myc-htff2 was subcloned into vector of pBluescript II sk(+) for identification of the fusion gene by restricting enzyme excision and DNA sequencing.Results Assembly of c-myc-TFF2 fusion gene(in vitro) and construction of pBS-TFF2 had been completed successfully;and DNA sequencing showed that the sequence of synthetic gene accorded with the expectation.Conclusion With the help of DNAWORKS program,the design and assembly of oligonucleotides (in vitro) is effective to synthesize a target gene,and the cloning vector of c-myc-htff2 fusion gene has been successfully constructed.

Objective To explore the correlation between expression of nuclear factor kappa B (NF-kappa B) in peripheral blood monouclear cells(PBMC) and the severity of coronary artery lesion in patients with acute coronary syndrome(ACS). Methods The 81 patients were diagnosed with coronary heart disease, and all of them underwent immediate or selective coronary angiography(CAG) The nuclear protein level of activated NF-B was detected by Western blot and semi-quantity image analysis was done. Coronary angiograms were scored according to Gensini integration. The relationship between NF-κB and Gensini score was analyzed. Results The protein expression of NF-κB in PBMC in ACS group was significantly higher than that in stable angina group and control group (0.85±0.18 vs. O.75±0.21 and 0.71±0.23, F=3.72, P<0.05). The protein expression of NF-κB was not correlated with Gensini score(r=0.07, P>0.05). Conclusions The ACS patients have the activation of NF-κB in PBMC. The protein expression of NF-κB is not correlated with Gensini score, which does not suggest an implication of the severity of coronary artery.

Objective To analyze the difference and correlation of the evaluation of the medical students' communication ability between the examiners,standardized patients (SP) and medical students themselves in objective structured clinical examination (OSCE),and to provide scientific basis for the appropriate evaluation method of medical students' communication ability.Methods OSCE was used to evaluate the communication ability of 90 medical students in Daping Hospital,Chongqing,and the three parties were evaluated by the examiners,SP and medical students themselves.Excel and SPSS 17.0 statistical analysis software were used,through Friendman M.test,t test and correlation analysis to analyze the differences and correlation of the three parties evaluations.Results The different evaluation between the three parties on the communication ability of medical students was as follows.Examiner's evaluation was the lowest (8.39 ± 1.18),SP's evaluation was the highest (9.62 ± 0.73),Medical students themselves' evaluation was higher (9.28± 1.09);The examiner's evaluation of Medical students' empathy,verbal communication ability,nonverbal communication ability and etiquette was lower (P=0.00).The correlation analysis of the three parties' evaluation showed that there was a significant correlation between the three parties on the connnunication ability,empathy and nonverbal communication ability (P＜0.05).The evaluation of SP and medical students themselves on medical students' language communication ability and etiquette was significantly correlated (P＜0.05).Conclusions Using examiner or SP or medical students themselves only to evaluate the communication ability of medical students is not accurate,The Examiner and SP as the main trial test personnel should collaborate to evaluate medical students' communication ability.The examiner can evaluate three projects such as what is medical ethics and law,empathy,nonverbal communication ability,while the SP can evaluate the two projects:what is language communication ability and etiquette.The collaborative evaluation of the two sides can be more accurate to reflect the doctor-patient communication ability of medical students.

Objective: To investigate the role and mechanism of histamine in regulation of C57BL/6 mice spleen derived LAK activity in vivo. Methods: The C57BL/6 mice carrying B16 pulmonary metastatic melanoma were treated with LAK/IL 2/histamine therapy or LAK/IL 2 therapy with the aim of evaluating both anti tumor responses in vivo. Results: It was found that the addition of histamine effectively potentiated the anti metastatic effect produced by LAK/IL 2 therapy and induced regression of NK resistant B16 pulmonary metastatic melanoma. Survival period was significantly prolonged in mice receiving LAK/IL 2/histamine as compared with LAK/IL 2 therapy alone. The effect of histamine was completely blocked by H 2 R antagonist ranitidine, and mimicked by dimaprit, a H 2 R agonist. Conclusion:Histamine, via specific activation of H 2 R, may be an important regulator of LAK cells activity; histamine and LAK/IL 2 synergistically induce more potent antitumor efficacy in vivo .

The transcription factor Oct-4 is expressed specifically in mammalian preimplantation embryos and its function is related to the maintenance of embryonic stem cell pluripotency. The functional role of the heterogenous expression of Oct-4 remains unclear however. A GFP reporter construct, pOct-4(p)-GFP was generated, containing the upstream regulatory regions of bovine Oct-4 gene and its expression pattern was evaluated in the developing embryos of mouse, pig and rabbit following intracytoplasmic sperm injection. GFP fluorescence was visible early at the 2-cell stage and then became stronger in the blastocysts of all three species. However, the distribution of the GFP signals was restricted to the cells of inner cell mass and no fluorescence was detectable in trophectoderm cells. These results suggest that the bovine Oct-4 promoter is functional and that its embryonic expression activity is similar in different mammalian species.
