3.AZT inhibit telomerase activity of squamous cell carcinoma of tongue
China Oncology 2001;0(02):-
Purpose:To study the effect of inhibition of telomerase activity and cell cycle by transcriptase telomerase inhibitors (3′ azido 3′ deoxythymidine, AZT) on squamous cell carcinoma of tongue in vitro.Methods:Human squmous cell carcinoma of tongue cell line Tca8113 was used as target cell. Telomerase activity was determined by TRAP PCR ELISA in untreated and treated Tca8113 by AZT, cell cycle phases were analyzed by flow cytometry. Results:Telomerase activity of Tca8113 was significantly inhibited when treated with AZT, and the effect of inhibition was dose dependant (rate of telomerase activity treated with AZT in 0.3, 0.6, 1.0, 1.5mol 10 -1 was 0.69 0.03, 0.61 0.08, 0.53 0.11, 0.50 0.02 respectively, rate of telomerase activity treated without AZT was 0.76 0.06). Cell cycle of treated Tca8113 was changed with marked increase in G 2 /M phase compared with untreated Tca8113 (62.8% vs 19.7%, P

To investigate the effects of TGF?antisense oligodexynucleotides(ASODN) and EGFR ASODN on human rectal carcinoma cell line HR8348. Cationic liposome, lipofectamine, were selected as delivery vector HR8348 cells were treated with ASODN in vitro. HR8348 cells with or without pretreatment were inoculated into nude mice. The proliferation and DNA synthesis of HR8348 cells treated with TGF-? ASODN and EGFR ASODN were greatly inhibited, and tumorigenic rate was also greatly reduced. TGF-? ASODN and EGFR ASODN could inhibit the proliferation of human colon cancer cell line in vitro as well as in vivo, the results implicate. The potential value in colorectal cancer gene therapy.
5.EXPRESSION AND SIGNIFICANCE OF CD44v6 PROTEIN IN SQUAMOUS CELL CARCINOMA OF THE TONGUE
Medical Journal of Chinese People's Liberation Army 2001;0(10):-
To study the expression and significance of CD44 splice variant V6 in squamous cell carcinoma of the tongue. The expression levels of CD44v6 protein were determined immunohistochemically in 40 squamous cell carcinoma of the tongue specimens (24 non metastatic primary tumors and 16 metastatic lymph nodes), 12 squamous cell papilloma and 9 normal tongue mucosa using murine exon V6 specific monoclonal antibody. The CD44v6 overexpression was detectable in 29 of 40 squamous carcinoma of the tongue, in 2 of 12 squamous cell papilloma, in 0 of 9 mormal mucosa, P

Objective To investigate the methods and effects of applying choledochoscope in drainage of retroperitoneal abscess.Methods Eighteen cases of retroperitoneal abscess,who underwent open surgical debridement and drainage or PCD but the drainage was ineffective,were selected for use of choledochoscope to irrigate and debride the abscess repeatedly.Results All of the 18 patients had effective choledoscopic treatment;in 17 patients the abscess healed and drainage catheter was successfully removed;but in one patient,who developed pancreatic fistula,was cured by internal drainage operation performed 6 months later.Conclusions Use of choledochoscope as an adjunctive treatment after drainage operation of retroperitoneal abscess is simple,safe,and effective.

Objective To construct Four in One informational teaching model based on cloud platforms, simulation training, nursing micro-lectures and multidimensional evaluation investigate, and to explore the effect of theFour in Oneinformational teaching model applied in Medical Nursing teaching. Methods Two classes students of 2014 were selected by randomized sampling and were divided into experiment group and control group, the experiment group operated the Four in One informational teaching mod, the control group operated regular teaching. After the experiment,using the medical nursing theory test, the skill test, the questionnaire survey to evaluate the teaching effectiveness. Results The theoretical examination score, skill examination score and overall results of experiment group were (78.81±6.44), (82.01±5.22), (80.41±6.32) points, while (71.12±8.12), (76.74±6.3), (75.57±5.51) points of control group, and the difference was statistically significant (t=5.47, 4.86, 3.22, P<0.01 or 0.05). The students' interested in the informational teaching model of the experimental group reached 78.72%(37/47) and learning satisfaction reached 91.48% (43/47). Conclusions The Four in One informational teaching model applied in Medical Nursing teaching can improve the study effect .

Objective To improve the diagnostic and therapeutic levels for spontaneous spinal epidural hematoma(SSEH) by summarizing the effect of microsurgery and clinical diagnosis of SSEH. Methods The therapeutic efficacy of 21 patients with SSEH undergoing microsurgery from March 1996 to March 2003 was retrospectively analyzed. Results On discharge from hospital, muscle strength of the bilateral lower extremities of 13 patients was restored to grades Ⅲ or Ⅳ, 5 to grade Ⅴ but no change was found in 3 patients. Conclusion Early diagnosis of SSEH and surgical treatment are helpful to restoring the function of the injured spinal cord and decrease of sequelae.
