摘要: 目的: 探讨热休克蛋白70(Hsp70)、细胞周期调节蛋白P27和肿瘤抗凋亡蛋白Bcl-2在涎腺黏液表皮样癌(MEC)中表达的临床意义。方法: 采用免疫组织化学通用型二步法检测40例MEC中Hsp70、P27及Bcl-2蛋白表达,并选用10例多形性腺瘤(PAS)作对照。结果: Hsp70及P27蛋白阳性表达均为细胞核及胞浆中呈棕黄色染色,在MEC中的阳性表达率分别为75%及27.5%,与对照组(PAS)(30%、90%)比较,差异均具有显著性(P<0.01)。而Bcl-2蛋白阳性表达为细胞浆染色呈棕黄色或棕褐色,在MEC中的阳性表达率为62.5%,与对照组(PAS,40%)比较差异无显著性(P>0.05)。MEC中Hsp70和P27蛋白表达在不同临床分期间、不同组织学分级间及有、无淋巴结转移组间比较,差异均具有显著性(P<0.05或P<0.01);Bcl-2蛋白表达在不同临床分期间比较,差异具有显著性(P<0.05),但在不同组织学分级间及有、无淋巴结转移组间比较,差异均无显著性(P>0.05)。结论: Hsp70与P27蛋白可作为判断患者预后的指标。Hsp70与Bcl-2可能通过不同的途径抑制细胞的凋亡。

Abstract: Abstract:Objective To study the expressions of Hsp70,P27,Bcl-2 in mucoepidermoid carcinoma of salivary glands and clinical significances.Methods Forty cases of mucoepidermoid carcinoma of salivary glands were chosen and the expressions of Hsp70,P27, Bcl-2 were detected by the method of immunohistochemistry,10 cases of polymorphic adenoma were chosen as control group.Results Both Hsp70 and P27 were stained with aliomycin in nucleus and cytoplasm,the positive rates of them were 75% and 27.5%, respectively,there were significant differences compared with control group (P<0.01).Bcl-2 was stained with aliomycin or brown,the positive expression rate was 62.5% and there was no significant difference compared with control group (P>0.05).The expressions of Hsp70 and P27 had significant differences in different clinical stages,different histological grades and lymph node metastasis(P<0.05 or P<0.01),the expression of Bcl-2 had significant difference in different clinical stages (P<0.05),while no significant difference in different histological grades and lymph node metastasis of mucoepidermoid carcinoma of salivary glands (P>0.05). Conclusion The expressions of Hsp70 and P27 can be used to estimate prognosis of patients with mucoepidermoid carcinoma.Hsp70 and Bcl-2 can inhibit apoptosis by different ways.

Key words: heat-shock proteins 70, cell cycle proteins P27, Bcl-2
