Abstract:
Objective To observe the expression of p57,CD34 and Ki-67 in complete hydatidiform mole (CHM),partial hydatidiform mole (PHM) and hydropic abortus (HA),so as to investigate the role of the expression in the diagnosis and differential diagnosis of edematous lesions of placental villi.Methods A total of 45 cases of CHM tissue,40 cases of PHM tissue,28 cases of HA tissue and 22 cases of normal pregnancy tissue were collected from January 2003 to December 2013 in Anqiu People's Hospital.The expression of p57,CD34 and Ki-67 in placental villi were detected by immunohistochemistry.Results The positive expression rate of p57 in CHM,PHM,HA and normal pregnancy tissues was 2.22％ (3/45),85.00％ (34/40),89.29％ (25/28) and 95.45 ％ (21/22),respectively;the positive expression rate of p57 in CHM tissues was significantly lower than that in PHM,HA and normal pregnancy tissues (x2 =59.908,57.055,58.238;P ＜ 0.01);there was no significant difference in the positive expression rate of p57 in PHM,HA and normal pregnancy tissues (x2 =0.022,0.681,0.074;P ＞0.05).The expression of CD34 in CHM,PHM,HA and normal pregnancy tissues was 10.27 ± 3.00,11.13 ±2.58,35.57 ± 2.36 and 35.55 ± 2.22 respectively;the expression of CD34 in CHM and PHM tissues was significantly lower than that in HA and normal pregnancy tissues (t =37.89,37.86,39.79,37.40;P ＜ 0.01).There was no significant difference in the expression of CD34 between HA and normal pregnancy tissues (t =1.485,P ＞ 0.05),and there was no significant difference in the expression of CD34 between CHM and PHM tissues (t =1.404,P ＞ 0.05).The positive expression rate of Ki-67 in CHM,PHM,HA and normal pregnancy tissues was 64.44％ (29/45),55.00％ (22/40),14.29％ (4/28) and 9.09％ (2/22) respectively;the positive expression rate of Ki-67 in CHM and PHM tissues was significantly higher than that in HA and normal pregnancy tissues (x2 =18.21,12.61,17.53,11.56;P ＜ 0.01);there was no significant difference in the positive expression rate of Ki-67 between HA and normal pregnant tissues (x2 =0.015,P ＞ 0.05),and there was no significant difference in the positive expression rate of Ki-67 between CHM and PHM tissues (x2 =0.787,P ＞ 0.05).Conclusion p57 helps to identify CHM and other edematous lesions of placental villi,CD34 and Ki-67 help to identify hydatidiform mole and HA.Combined detection of p57,CD34 and Ki-67 is helpful for differential diagnosis of CHM,PHM and HA.
