Transforming growth factor-beta is has one of the important fibrosis induced by cytokines, and connective tissue growth factor is considered to be downstream of the TGF-beta factor, mediated by specificity of fibrosis of TGF-beta 1 [1]. At present, CTGF has become the new focus of the study area.

It has one of the important cell factors that causes the fiber function to transform growth factor - β, and connective tissue growth factor considered to be TGF - downstream factor of β, specificity lie between lead TGF - 1 β urge fiber take function [1 ]. At present, it is new and hot that CTGF has
