Objective To evaluate the outcomes of video-assisted thoracoscopic(VATS)lobectomy for patients with clinical stage I lung cancer. Methods 30 patients with clinical stage I lung cancer underwent VATS lobectomy with complete mediastinal lymphadenectomy from November 1997 to October 2000.Male 19, female 11 ranged in age from 36 to 78 years with a mean of 63 1 years. Results No perioperative death occurred .Two cases(6 67%) were given blood fransfusion and complications were found in 4 coses(13 3%).During the follow-up period lasting 12 months to 45 months with a mean of 28 7 months the overall survival rate,when all stages were calculated,was 83 3%(25/30).For stage I survival rete was 90 9%(20/22). Conclusions VATS lobectomy with systemic lymphadenectomy is a safe and reliable approach for stage I lung cancer,by which an excellent long-term outcome can be achieved.

Objective To explore the relationship between ulcerative colitis (UC) susceptibility and tumor necrosis factor superfamily member (TNFSF) 15 gene polymorphisms and haplotypes in Han nationality in Zhejiang province of China. Methods A total of 408 UC patients and 574 healthy controls were recruited in this study. Three single nucleotide polymorphisms of TNFSF15 (rs3810936, rs4263839, rs4979462) were examined by improved multiple ligase detection reaction (iMLDR) technique. Analyses of linkage disequilibrium (LD) and haplotype were performed by Haploview 4.2 software in all study subjects. Results The variant allele A and genotype (GA+AA) of rs4263839 were less frequent in UC patients than in controls (45.34% vs. 50.17%, P=0.035; 68.38% vs. 76.66%, P=0.004). According to the severity and location of disease, UC patients were divided into different subgroups. After multiple comparison correction (α=0.012 5), the frequencies of variant allele A and genotype (GA+AA) of rs4263839 were lower in patients with severe UC than in the controls (37.69% vs. 50.17%, P=0.007;60.00% vs. 76.66%, P=0.004). Similar findings were also drawn for patients with extensive colitis in contrast with the controls (42.22% vs. 50.17%, P=0.009; 63.33% vs. 76.66%, P<0.001). Furthermore, the haplotype analysis indicated that three SNPs above were in a strong LD. The frequency of haplotype TAC was lower in UC patients than in the controls (40.83% vs. 46.04%, P=0.023). Also it was less prevalent in patients with severe UC and patients with extensive colitis when compared with controls respectively (33.38% vs. 46.04%, P=0.005;37.22% vs. 46.04%, P=0.003). Conclusions TNFSF15 (rs4263839) variation might not only reduce the risk of UC, but also affect the severity and lesion location of UC. The haplotype TAC formed by rs3810936, rs4263839 and rs4979462 might be related to a lower risk of UC, especially in patients with severe colitis or patients with extensive colitis.
