Abstract
Objective：To study the relation between the expressions of nm23－H1 as well as MVD and SCT features in colorectal carcinoma with serosa invasion.
Methods：Relate to the various invasion depth of colorectal carcinoma in SCT features，analysis of the MVD and the expression of nm23－H1 in 42 cases was obtained by using immunohistochemical streptavidin peroxidase conjugate method.
Results：In the serosa－invasion group and the non－serosa－invasion group of 42 cases in SCT features，the microvessel densities was a remarkable difference （t.=－2.852，P=0.007） and the positive rates of nm23－H1 was no remarkable difference（x2=0.318，P=0.710）between them. The difference of microvessel densities between the nm23－H1－positive group and the nm23－H1－negative group was significant（t=－2.149，P=0.038）. |
