The goal of graduate students'cultivation is training talented persons with creativity.Academic forum plays an important role in graduate students' cultivation,which can stir up graduate students'creative thought and bring an atmosphere of studying hard.

Objective: To investigate the methylation status of the promoters of RASSF1A and BLU genes in the renal carcinoma tissues and to assess their roles in the tumorigenesis of renal carcinoma. Methods: Methylation specific PCR (MSP) method was used to examine the methylation status of the promoters of RASSF1A and BLU genes in the renal carcinoma tissues of 26 patients with renal carcinoma and their corresponding adjacent normal tissues; and the results were analyzed. Results: We found that 17 (65.4%) of the renal carcinoma tissues had abnormal methylation of RASSF1A gene, and there was no abnormal methylation of RASSF1A in the adjacent normal tissues. Eleven(42.3%) of 26 renal cancer tissues had hypermethylation of BLU gene, and there was no hypermethylation of BLU gene in the corresponding adjacent tissues. Conclusion: Hypermethylation of RASSF1A and BLU genes is present in the renal carcinoma tissues, suggesting the hypermethylation of RASSF1A and BLU might be associated with the tumorigenesis of renal carcinoma.

Objective To study the feasibility of laparoscopic total mesorectal excision(TME) for low rectal cancer.Methods Laparoscopic total mesorectal excision was performed in 126 patients with low rectal cancer according to TME principle.Results The operation time was 95 - 180 min,with an average time of ( 117 ± 21 ) min,the amount of bleeding 50 - 200 ml,with an average amount of (90 ± 27 ) ml.2 - 3 days after surgery,gastrointestinal function was restored.Hospital stay was 6 - 14 days,with an average of (8 ± 2)days.Four cases converted to open surgery,the conversion rate for laparotomy was 3.2％.The proportion of sphincter-preserving operation was 95.24％ (120/126).No instant or delayed injury of ureters,large bleeding in front of sacrum and other operation-related severe complications happened intra-and after operation.Conclusion Laparoscopic surgery for low rectal cancer is safe and feasible.

Chemoprevention is the use of natural or synthetic substances to prevent、suppress or to reverse the development of colorectal cancer.Aspirin and cox-2 inhibitor are the most effective preventive agents.However,the gastrointestinal and cardiovascular adverse effects limit the application.Recurrent adenomas can be markedly reduced by a combination of difluoromethylornithine and sulinclac and with few side effects.5-aminosalicylate and ursodeoxycholic acid have become the focus of inflammatory bowel disease.The double roles of folate need further study.Statins and EGFR inhibitors have some effects,which are in early clinical studies.The article reviews the new progress of chemoprevention of colorectal cancer.

Objective To observe the therapeutic efficacy of different operative methods for nasal septal spur/ridge elevated deviation. Methods A total of 134 patients with nasal septal spur/ridge elevated deviation were randomly divided into endoscopic surgery group and control group. Patients in the endoscopic group were treated with nasal septoplasty under intranasal endoscopy, while those in the control group were treated with traditional submucous correction of nasal septum. Therapeutic effects and causes of operative success were analyzed. Results The therapeutic efficacy in endoscopic surgery group was significantly superior to that in the control group ( P

Objective To explore change and significance of serum and urinary transforming growth factor-? 1(TGF-? 1)in the patients with primary chronic glomerulonephropathy (PCG). Methods 65 patients with PCG were divided into four groups according to the degree of renal function damage: normal renal function,renal compensatory,renal decompensatory and renal function failure groups. Levels of serum and urinary TGF-? 1 were determined with ELISA, and the levels of urinary protein and renal function were examined as well. Results Levels of serum and urinary TGF-? 1 in patients with PCG were singificantly higher than those in control, and the levels of serum and urinary TGF-? 1 among four groups were significantly different. The TGF-? 1 level of urinary was associated with the degree of renal function damage(r=0 28,P
