Abstract:
Objective To explore the role of cell cycle regulators in tuberculosis with lung carcinoma.Methods p53,MDM_2,p21~ ras and p21~ WAF1 proteins were detected by LsAB immunohistochemical technique in 69 cases of tuberculosis with lung carcinoma.Results As compared with primary tuberculosis with lung carcinoma,the expression rate p53 or MDM_2 protein in relapsing NPC was similar(78% to 80%,84% to 83%),and the expression rate of p21~ ras and p21~ WAF1 protein in relapsing NPC was obviously descended(73% to 93%,52% to 84%);The high-expression rate of p53 protein in relapsing NPC was similar(42% to 51%),the high-expression rate of MDM_2 protein in relapsing NPC was obviously risen(57% to 32%),and the high-expression rate of p21~ ras and p21~ WAF1 protein in relapsing NPC was obviously descended(16% to 65%,17% to 46%).Among of them,the significant rise of MDM_2 protein expression level in relapsing NPC mainly occurred in the patients of group 2 which relapsing-interval was shorter than 34 months(P
