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
2.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.
3.Epstein-Barr virus and inflammatory bowel disease
Journal of Chinese Physician 2016;18(9):1281-1284
Epstein-Barr Virus (EBV) is the first human virus related to oncogenesis.EBV infection is associated with inflammatory bowel disease (IBD) with unknown causality.The prevalence of EBV in intestinal tissue from patients with IBD is significantly higher and related to the exacerbation of the disease and refractory IBD.Immunosuppressive therapy has improved outcomes associated with IBD.However,it is also associated with an increased risk of opportunistic infection,and lymphoproliferative disorders (LDs) maybe due to EBV infection.Here we review our current understanding of the pathogenesis of EBV infection in colonic mucosal inflammation,EBV-induced disease exacerbation,lymphomagenesis in IBD,and clinical approaches therefrom.

Chinese Journal of Primary Medicine and Pharmacy 2016;23(22):3400-3403
Objective To compare the clinical effect and safety of two kinds of quadruple therapy on the basis of omeprazole and rabeprazole in the treatment of patients with active gastric ulcer and Hp positive.Methods 104 patients with active gastric ulcer and Hp positive were chosen,and they were randomly divided into two groups including A group (52 patients)with omeprazole treatment,and B group (52 patients)with rabeprazole treatment on the basis of amoxicillin +clarithromycin +bismuth potassium citrate.The clinical efficacy,clinical symptom remission rate in 7d,14d and 28d after treatment,HP eradication rate,recurrence rate with follow -up and adverse reaction inci-dence of 2 groups were compared.Results The clinical cure rate of B group was significantly higher than A group (36.54% vs.19.23%)(χ2 =8.74,P <0.05).There was no significant difference in the clinical total effective rate between the two groups(P <0.05).The clinical symptom remission rates in 7d and 14d after treatment of B group were significantly higher than A group(96.15% vs.76.92%,96.15% vs.78.85%,98.08% vs.82.69%;98.08%vs.84.62%,100.00% vs.82.69%,100.00% vs.88.46%)(χ2 =8.74,7.20,7.91;7.05,6.86,6.33;all P <0.055).The Hp eradication rate of B group was significantly higher than A group(92.31% vs.73.07%)(χ2 =9.24,P <0.05).The recurrence rate of B group was significantly lower than A group(7.69% vs.25.00%)(χ2 =10.62,P <0.05).The incidence rate of adverse reaction of B group was significantly lower than A group(3.85% vs. 13.46%)(χ2 =7.85,P <0.05).Conclusion Compared with omeprazole,quadruple therapy on the basis of rabe-prazole in the treatment of patients with active gastric ulcer and Hp positive can effectively relieve the digestive symp-toms,promote ulcer repair process,higher the Hp removal effects,prevent the long -term recurrence and is helpful to reduce the adverse drug reactions risk.
5.Application of EGFR-TKI in locally advanced non-small cell lung cancer
Journal of International Oncology 2016;43(4):312-314
With the deepening of the lung cancer molecular biology research,small molecular targets antitumor drugs make breakthrough progress,the epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is one of the most attention drug.A series studies show that EGFR-TKI can enhance the antitumor activity of ionizing radiation.Therefore,EGFR-TKI combined with radiotherapy alone for poor-risk patients appears survival benefit,but can't ignore the lung toxicity.However,there is a big contro-versy that EGFR-TKI combined with chemoradiotherapy for locally advanced NSCLC.

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.
8.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.

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.
10.Correlation analysis of HPV and cervical cancer
Chinese Journal of Primary Medicine and Pharmacy 2013;20(21):3285-3287
Objective To investigate the correlation between HPV positive rate and incidence rate of cervical cancer.Methods 438 women,who reveived cervical Pap smears and biopsy,were included in the present study.Human papilloma virus nucleic acid amplification genotyping assay kit was used to detect 21 kinds of HPV subtypes.Results There were 102 patients with cervical cancer (23.29%) and HPV-positive 94 patients (21.46%),which had no significance difference (x2 =0.421,P =0.517).There were 56 patients HPV16 positive (54.90%),19 patients HPV58-positive (18.63%),12 patients HPV18 positive (11.76%) and 8 patients HPV52 positive (7.84%),which were significantly higher than those of other types of HPV-positive rate(all P < 0.05).The proportion of the patients with invasive cervical cancer in HPV i6,HPV58,HPV18,or HPV52-positive was significantly higher than that of intraepithelial lesions and carcinoma in situ (all P < 0.05).Conclusion HPV16,HPV58,HPV18,and HPV52 have high correlation with uterine cancer.
