Abstract: ObjectiveTo study the heat shock protein 47 ( HSP 47 ) andtype Ⅰ ,Ⅲ collagen relevance expression in keloid tissue. MethodsUSE immunohistochemistry to detect 21 patients( HS group) pathological keloid tissue HSP47, Ⅰ-type, Ⅲ collagen levels,and normal foreskin(control group) compared to the expression of HSP 47 and Ⅰ and Ⅲ collagen. ResultsHS group HSP 47 scar absorbance was( A value) ( 133.0 ± 58.7) ,it was significantly lower than the control group( 169.6 ± 53.2) ( t =2. 697 ,P =0.024) ;two groups of collagen type Ⅰ, Ⅲ collagen levels had statistically differentce(t =14.898,12.610,all P =0.000) ; HSP 47 level and type Ⅰ collagen were positively correlated(r =3.058,P =0. 034),and type Ⅲ collagen content was also positively correlated(r =4. 610, P =0. 029). ConclusionHSP 47 in keloid tissue could cause dermal layer assembly of collagen synthesis and significantly increased,and it was an important mechanism for the formation of keloids.
