ABSTRACT
Objective To explore the changes of serum tryptase(TPS)and interleuk-6 (IL-6)levels before and after TACE treatment in patients with hepatocellular carcinoma (HCC).Methods ELISA was used to detect the serum TPS and IL-6 levels in 5 1 patients with HCC 1 day before and 1 day,1 week and 1 month after TACE.30 healthy people were enrolled as a control group.Results Serum TPS and IL-6 levels in observation group before TACE were higher than those in control group (P＜0.05),and serum TPS level in the observation group was positively correlated with serum IL-6 level (P＜0.05)before TACE.Serum TPS and IL-6 levels in the response group one month after TACE were lower than those one day before TACE (P＜0.05),while compared with those one day before TACE ,the non-response group increased slightly and non significance was showed(P＞0.05).Conclusion Serum TPS and IL-6 levels are closely related to the response of HCC to TACE treatment,thus these may be used to evaluate the efficacy of TACE in treatment of HCC.
ABSTRACT
Taenia pisiformis is one of the most important parasites of canines and rabbits. T. pisiformis cysticercus (the larval stage) causes severe damage to rabbit breeding, which results in huge economic losses. In this study, the genetic variation of T. pisiformis was determined in Sichuan Province, China. Fragments of the mitochondrial cytochrome b (cytb) (922 bp) gene were amplified in 53 isolates from 8 regions of T. pisiformis. Overall, 12 haplotypes were found in these 53 cytb sequences. Molecular genetic variations showed 98.4% genetic variation derived from intra-region. F(ST) and Nm values suggested that 53 isolates were not genetically differentiated and had low levels of genetic diversity. Neutrality indices of the cytb sequences showed the evolution of T. pisiformis followed a neutral mode. Phylogenetic analysis revealed no correlation between phylogeny and geographic distribution. These findings indicate that 53 isolates of T. pisiformis keep a low genetic variation, which provide useful knowledge for monitoring changes in parasite populations for future control strategies.
