Indwelling hepatic arterial catheter of fulfilling lipiodol treatment for giant primary hepatic carcinomas / 介入放射学杂志

Objective To investigate the clinical value of indwelling hepatic arterial catheter in splitting fullfilling of lipiodol treatment for giant primary hepatic carcinomas. Methods Sixteen patients with giant primary hepatic carcinomas under DSA guidance,splitting lipiodol embolizations were carried out through indwelling hepatic arterial catheter everyday until the lipiodol with fulfilling the tumors. Total forty times (average 2.5 individually)of interventional treatment were accomplished in these patients. Liver function and short-term effect after interventional therapy were observed. Results None of these 16 patients had serious liver function damage and recovered uneventfully after general protective care. PR and SD were achieved in 9 and 7 cases respectively,3 months after this interventional procedure. PD was not found. Conclusions Indwelling hepatic arterial catheter in fulfilling of lipiodol treatment for giant primary hepatic carcinomas is not only unlikely to cause serious liver function damage,but also can completely embolize the tumor quickly,therefore worthy to be recommended clinically.

Study on the single nucleotide polymorphisms of TNF-? of gene in the promoter region in three main ethons population in Guizhou province / 中国免疫学杂志

Objective:To study single nucleotide polymorphisms in the promoter region of TNF-? gene in Chinese Han,Miao and Buyi population in Guizhou province.Methods:The five polymorphism sites at-1031,-863,-857,-308,-238 in TNF-? gene promoter region were detected using PCR-RFLP and SSP-PCR.Results:The allele frequencies of TNF-? gene in promoter region in these three main ethons of population were observed.In Chinese Han population,the-238 G was 96% and-238 A was 4%.Inaddition,-308 G was 92% and-308 A was 8%,-857 C was 65% and-857 T was 35%,-863 C was 80% and-863 A was 20%,-1031 T was 48% and-1031 C was 52%;In Miao people,the frequency at the loci above were 15.0%,8.0%,26.0%,4.0% and 50.0%;And the frequency of these five loci above were 14.0%,6.0%,11.0%,16.0% and 50.0% in Buyi population.Conclusion:Single nucleotide polymorphisms of TNF-? gene exhibits some specific characters in Chinese Han and Miao and Buyi population in Guizhou province.
