1.Construction of pEGFP-N1-Fcy::Fur recombinant plasmid and observation of its expression in ovarian cancer cells
Journal of Chongqing Medical University 2007;0(11):-
Objective:To construct a EGFP(Enhanced green fluorescent protein)-labled euk-aryotic expression plasmid of Fcy::Fur suicide gene and to detect its expression in SKOV3 cell line. Methods:With the technology of gene re-arrangement,Fcy::Fur gene in pORF-Fcy:Fur plasmid was subcloned into pEGFP-N1 vector,with its correctness evaluated by the means of r-estriction enzyme analysis and sequencing.It was transfected into SKOV3 cells with lipofectin,the transient expression of GFP was observed under flu- orescence microscope after 24 hours and detected by Western blot. Results:Correct construction of pEGFP-N1-Fcy::Fur was identi- fied by methods of restriction enzyme analysis and nucleotide sequence determination.A total of 60% transfe-cted cells emitted out green fluorescence under fluorescent microscope after 24 h after transfecti-.on. Fcy::Fur gene expressed by the transfected cells were testified by Western blot. Conclusion:The recombinant eukaryotic expression vectors have been constructed successfully and effec- tive-ly expressed in ovarian cancer cells,which may provide an experimental basis for gene therapy of ovarian cancer.

China Oncology 2000;0(06):-
Purpose:Evaluate the prognostic factors in invasive vulvar cancer.Methods:Fifty one cases with invasive vulvar cancer admitted in our hospital from 1980 to 1999 were retrospectively analyzed.Results:Thirty six patients had squamous cell carcinoma and 27 of them were well differentiated and 6 moderately differentiated and 3 poorly differentiated ,three had adenocarcinoma, three had basal cell carcinoma ,three had leimyosarcoma , six had malignant melanoma. Thirteen cases (25.4%) were in FIGO stage Ⅰ;29 (56.7%) in stage Ⅱ;7(13.1%) in stage Ⅲ and 2(3.9%) in stage Ⅳ. The 5-year survival rates of stage Ⅰ,Ⅱ,ⅢandⅣwere 81.5% , 68.4% , 41.2% and 0.0% (P
3.Application of i-gel laryngeal mask combined with T-seal adapter in painless bronchoscopy
The Journal of Practical Medicine 2015;31(15):2483-2485
Objective To observe the clinical effect of controlled ventilation with i-gel laryngeal mask airway in painless bronchoscopy. Methods 80 patients were randomly divided into control group (group A, n =40) and surface anesthesia group (group B, n = 40). Fent-anyl, ruifentanyl, propofol, succinylcholine anesthesia and controlled ventilation was adopted by i-gel laryngeal mask combined with T-seal adapter in control group.Surface of lidocaine anesthesia, spontaneous breathing, nasal cannula oxygen were applied in surface anesthesia group. Patients vital signs change in bronchoscopy , endoscopic related adverse reactions such as body movement, cough, laryngospasm. anesthesia related adverse reactions such as postoperative bucking, choking hoarseness, examination time and patient satisfaction were recorded. Results Controlled ventilation with i- gel laryngeal mask shows airway changes are small (P < 0.05), and less adverse reaction (P < 0.05). Patients showed higher satisfaction (P < 0.05). Conclusion controlled ventilation with i-gel laryngeal mask in painless bronchoscopy is safe , controls the airwayeffectively , and solve the problem of respiratory depression , which proves to be a feasible method.
4.Progression of brain tumor stem cell markers
Journal of International Oncology 2014;41(12):899-901
Brain tumor stem cells (BTSCs) play a key role in tumorigenesis and tumor development.There are a group of special markers in the surface of brain tumor stem cells,which can sorts stem cells,precursor cells and cancer stem cells.In recent years,the studies of CD133,Nestin,high-mobility group A1,A2B5 have made some breakthroughs.
5.Molecular mechanisms of macrophage migration inhibition factor on hepatic cell carcinoma
Journal of International Oncology 2008;35(7):524-527
Many studies indicate that macrophage migration inhibition factor(MIF)is over-expressed in tumor cells,and is involved in the carcinogenesis and tumor development by multiple methods and ways.The complicated molecular mechanisms are not quite clear,and the studies about MIF in digestive tumors,especially in hepatic cell carcinoma become more and more.
6.Effect of Shenfu Injection on expression of HO-1 and iNOS in renal failure rats induced by intestinal ischemia-reperfusion
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(07):-
Objective:To explore the effect of Shenfu Injection (SFI) on expression of Heme oxygenase-1 (HO-1) and iNOS (inducible nitric oxide synthase) in renal failure rats induced by intestinal ischemia-reperfusion (IR) and its possible mechanism. Methods:The model of intestinal ischemia-reperfusion was induced by clamping superior mesenteric artery for one hour and then releasing the arterial clamp for six hours. Wistar rats were randomized into three groups:IR+normal saline group,IR+SFI group and control group (C group). The serum creatinine and blood urea nitrogen were observed respectively. Expression of HO-1 and iNOS in rat kidney tissue was detected by immunohistochemitry and morphometry computer image analysis. The histological change of kidney was observed under light microscope. Results:①Compared with C group,expression of HO-1 and iNOS increased markedly in IR+ normal saline group (P
7.Quantitative analysis and prediction of literatures on research and application of Intralipid
Parenteral & Enteral Nutrition 1997;0(01):-
Intralipid is a kind of important fat emulsion.It has been widely used clinically in severely ill patients,especially in the patients before and or after major operation since the 1980s.After retrieving the papers on Intralipid form MEDLINE CD ROM database from 1980 to 1994 and analysing them by linear regression analysis in literature metrology,We found a significant linear correlation between the yearly literature quantity and the dynamic time course (year).From 1980 to 1994,the average yearly growth rate of the literature was 1.16.According to the regression equation,it is predicted that the literature on Intralipid will increase at a rate of 2.07% per year.From this analysis,we think that the research of Intralipid is tending to stability and will be wonderful.
8.Effects of liqustraxin on dysfunction of myocardial nuclear calcium transport
Chinese Journal of Clinical Pharmacology and Therapeutics 2000;0(02):-
AIM: To observe the dysfunciton of myocardial nuclear calcium transport in rat myocardial injury and the effects of liqustraxin on it. METHODS: The model of myocardial damage was induced by subcutaneous injection of isoproterenol (ISO,5 mg?kg -1?d -1). Myocardial nuclei were purified with sucrose density centrifugation and identified zymologically. The activity of Ca 2+-ATPase was measured zymologically and calcium uptake was assayed with 45Ca 2+ isotope. RESULTS: Compared with the control,the Ca 2+-ATPase activity of myocardial nuclear membrane in ischemia group(exprimental) was decreased by 18.1% (P

Chongqing Medicine 2014;(16):1983-1984,1987
Objective To observe the effect of intellectual activity on the cognitive function of the elderly.Methods The longi-tudinal follow-up study and the cross-sectional study were undertaken among physical examination people.The intellectual activity group (92 cases,more than 60 years old)often to take part in any one or more of the following activities for 5 years and above:pla-ying chess,playing the game of go,playing mahjong,playing cards,playing checkers,calligraphy,painting,reading,etc.The frequen-cy of intellectual activity was more than once per week at least.According to gender,age and educational level,92 cases were screened out as the control group and the control group was not to take part in above-mentioned intellectual activities or occasionally attend.The respondents had no baseline cognitive impairment.MoCA,MMSE,ADL and self-made questionnaire were adopted to conduct the evaluation.One year later when health check-up,the above-mentioned scales were used to evaluate again.The score changes were compared between the control group and experimental group.Results When enrolling,there was no significant differences in the MoCA scores,MMSE scores and ADL scores between the two groups.One year later,the comparison of the MMSE scores and ADL scores between the control group and experimental group had no significant difference (P>0.05).The Mo-CA scores manifested 2 cases (2.2%)of below the critical value of cognitive impairment in the experimental group and 6 cases (6.5%)in the control group,reaching the mild cognitive impairment(MCI)standards,the difference between the two groups showed the statistical significance (P<0.05).Conclusion The intellectual activity may be beneficial for the prevention of cognitive decline of the elderly and the MoCA scale is more suitable for screening MCI.
