Objective To observe the effect of human telomerase reverse transcriptase-thymidine kinase/ganciclovir (phTERT-TK/GCV) system combined human telomerase reverse transcriptase-tumstatin (phTERT-tumstatin) system on apoptosis of human HepG2 and mRNA expression and protein content of AFP,RhoC related with cancer.Methods Fluorescence microscopy was used to observe expression of EGFP and MCHERRY in transfected HepG2 and L-02.Real-time PCR and Western blot were used to detect AFP and RhoC mRNA and protein content.Flow cytometry was used to detect the apoptosis of transfected HepG2.Results phTERT-tumstatin and phTERT-TK/GCV genes expressed in transfected HepG2.Real-time PCR showed that AFP and RhoC mRNA expression in different group were 0.76±0.09 and 0.80±0.04 (TK/GCV group),0.62±0.09 and 0.40±0.02 (TM group),0.49±0.07 and 0.54±0.03 (MK group).The differences were significant (P ＜ 0.01) except TK/GCV group compared with empty plasmid group.Western blot test results showed that protein content of AFP and RhoC were higher in TK/GCV group (0.97±0.02/1.17± 0.01),TM group (0.83±0.02/0.99±0.02),MK group (0.69±0.01/0.77±0.02) than in empty plasmid group (1.19±0.03/1.32±0.05) and non-transfected group (1.15±0.05/1.29±0.30) (P ＜ 0.01).Additionally,protein content of AFP and RhoC in MK group were significant difference with TK/GCV group and TM group (P ＜ 0.01).Flow cytometry showed that phTERT-tumstatin,phTERT-TK/GCV co-transfected HepG2 cells apoptosis rate was significantly higher than both individually transected group.Cells apoptosis rate of alone and co-transfected groups was significant difference compared with empty vector group and untransfected group.Conclusions The effect of phTERT-TK/GCV and phTERT-tumstatin on pro-apoptotic of HepG2 cells is significant.phTERT-TK/GCV combined with phTERT-tumstatin has strong therapeutic function.

This article was aimed to analyze literatures on preventive treatment of disease in acupuncture and moxi-bustion in order to understand its status and development trend. Bibliometrics and statistics method in NoteExpress were used in the analysis of related literatures about preventive treatment of disease in acupuncture and moxibustion from 1981 to 2013, which were included in CNKI. The analysis and research were from aspects such as year distri-bution, keyword, journal distribution, author distribution, and fund distribution. The results showed that there were 537 articles in total from 1981 to 2013. The number of literatures was in an overall growing trend.“Zusanli”,“Inner Canon of Huangdi”,“sub-health”, and“clinical research”were high frequency keywords. The journal distribu-tion conformed to the Brad Ford’s law. The author distribution conformed to the Lotka’s law. The number of fund papers was also increased. It was concluded that research on preventive treatment of disease in acupuncture and moxibustion was still in the period of rapid development and had not reached maturity. The preventive treatment of disease in acupuncture and moxibustion had broad application prospects. However, the research still required to be strengthened.

Objective To investigate the risk factors and prevention of the ERCP-related upper gastrointestinal bleeding in patients with choledocholithiasis.Methods The clinical data of 678 patients who received ERCP in Yijishan Hospital of Wannan Medical College between January 2014 and December 2014 were reviewed.Univariate and multivariate analyses were performed to define the independent risk factor(s) for delayed hemorrhage following ERCP.Results A total of 383 patients,in whom 157 were males and 226 were females,the age ranged from 19 to 88 years,were recruited to the study.ERCP-related upper gastrointestinal bleeding occurred in 41 patients(10.7％),intraoperative bleeding occurred in 27(7.0％) and postoperative hemorrhage in 14 (3.7％).Twenty-eight cases were mild bleeding,9 moderate (4 caused by laceration of the cardiac mucosa) and 4 were severe bleeding.All patients recovered and were discharged,and no death occurred.No single case required surgical conversion.Univariate analysis revealed that cholangitis,medical history of aspirin/clopidogrel,giant diverticulum and the major papilla inside the diverticulum were risk factors for delayed hemorrhage following ERCP (P ＜ 0.05).Multivariate analysis indicated that independent risk factors were associated with cholangitis (OR =4.125,95％ CI:1.306-13.031,P ＜ 0.05),medical history of aspirin/clopidogrel (OR =10.220,95％ CI:2.997-34.853,P ＜ 0.01) and major papilla occurred inside the diverticulum(OR =14.064,95％ CI:1.888-104.762,P ＜ 0.05).Conclusion Cholangitis,medical history of aspirin/clopidogrel and major papilla at the diverticulum may increase the risks for upper gastrointestinal bleeding in ERCP in patients with choledocholithiasis.However,the hemorrhage should be actively managed,especially in endoscopy,once the bleeding occurs.

Background:Ulcerative colitis-associated colorectal cancer(UcCRC)is the most serious complication of ulcerative colitis(UC). 5-Aminosalicylic acid(5-ASA)could reduce the risk of UC progressing to UcCRC. Aims:To investigate the effect of 5-ASA on cell proliferation,apoptosis and cell cycle in human colon cancer cell line HT-29 for verifying the inhibitory effect of 5-ASA on UcCRC. Methods:HT-29 cells were treated with different concentrations(0,10,20,30, 40 mmol/ L)of 5-ASA. Cell proliferation was measured by CCK-8 assay. Cell apoptosis was determined by TUNEL method. Cell cycle was analyzed by flow cytometry. Expressions of cell mitotic regulators AuroraB and BubR1 were determined by immunohistochemistry. Results:Proliferation inhibition rates and apoptosis rates of HT-29 cells in 5-ASA 10,20,30,40 mmol/ L groups were increased with increase in concentration of 5-ASA(P ﹤ 0. 05). Proportions of cells in phase G0 / G1 in 5-ASA 30,40 mmol/ L groups were significantly lower than those in 5-ASA 0,10,20 mmol/ L groups (P ﹤ 0. 05);proportions of cells in phase S in 5-ASA 0,10,20,30 mmol/ L groups were significantly lower than that in 5-ASA 40 mmol/ L group(P ﹤ 0. 05);while proportions of cells in phase G2 / M in 5-ASA 30,40 mmol/ L groups were significantly higher than those in 5-ASA 0,10,20 mmol/ L groups(P ﹤ 0. 05). Mean optical density(MOD)values of AuroraB and BubR1 were decreased with increase in concentration of 5-ASA(P ﹤ 0. 05). Concentration of 5-ASA was positively correlated with proliferation inhibition rate and apoptosis rate of HT-29 cells(P ﹤ 0. 05),but was negatively correlated with MOD values of AuroraB and BubR1( P ﹤ 0. 05). MOD values of AuroraB and BubR1 were negatively correlated with proliferation inhibition rate and apoptosis rate of HT-29 cells as well as proportion of cells in phase G2/ M (P ﹤0. 05),but were positively correlated with proportion of cells in phase G0/ G1(P ﹤0. 05). MOD value of AuroraB was positively correlated with MOD value of BubR1(P ﹤ 0. 05). Conclusions:5-ASA can inhibit proliferation and induce apoptosis in HT-29 cells,the mechanism may be related to inhibiting expressions of AuroraB and BubR1 and the resulted effect on cell cycle.
