The expression of P57kip2 and its clinical significance in hilar bile duct adenocarcinoma / 中华肝胆外科杂志

Objective To study the expression of P57kip2 and its clinical significance in hilar bile duct adenocarcinoma.Methods The expressions of P57kip2 in hilar bile duct adenocarcinoma tissues (37 cases) and normal bile duct tissues (32 cases) were determined by immunohistochemical SP methods.The relations between the expression levels of P57kip2 with clinicopathologic parameters were analyzed.Results The positive rate of P57kip2 was 43.2％ (16/37) in bile duct adenocarcinoma,while it was 87.5％ (28/32) in normal duct tissues (P ＜0.01).The expression level of P57kip2 in adenocarcinoma showed no significant association with gender,age or CA19-9 level (P ＞0.05),but they were significantly related with lymph node metastasis,invasion and degree of differentiation (P ＜ 0.05).Conclusions P57kip2 is associated with the occurrence and development of hilar bile duct adenocarcinoma.It may play an important role in invasion and metastasis of hilar bile duct adenocarcinoma.The P57 protein can be used as an index to diagnose hilar bile duct adenocarcinoma.

Expression of p57~(kip2) protein in bladder transitionalcell carcinoma and its significance / 重庆医科大学学报

Objective:To assess the relation and clinical significance between p57 kip2 protein and the biological behavior of bladder transitional cell carcinoma(BTCC).Methods:The expression of p57 kip2 protein and PCNA was detected in 50 cases of BTCC,14 normal bladder mucosa by immunohistochemical method.Results:Positive rate of p57kip2 protein in BTCC was 46%,which was significant lower than 78.6% in normal bladder muscosa.( ? 2=4.660, P 0.05);positive rate of PCNA in BTCC was 60 %(30/50),which was significantly higher than 0%(0/14) in normal bladder mucosa( ? 2=15.812, P

Expression of p57~(kip2) and cyclin D1 in human glioma and its clinical significance / 西安交通大学学报(医学版)

Objective To investigate the expression of p57kip2 and cyclin D1 in human brain glioma and its clinical significance.Methods The expression of p57kip2 and cyclin D1 was detected by SP immunohistochemical technique in brain glioma(n=55) and normal brain tissues(n=10).Results Positive rate of p57kip2 protein in the 55 cases of brain glioma was 38.2%(21/55),significantly lower than that in normal brain tissues(80%,P
