| 中文摘要: |
| 目的：观察脑源性神经生长因子(BDNF)及其受体酪氨酸激酶受体B(TrkB)在子宫内膜癌中的表达，并分析其临床意义。方
法：采用免疫组织化学染色方法对11 例正常子宫内膜、16 例增生子宫内膜、31 例子宫内膜癌组织进行BDNF及其受体TrkB表达
的检测，并分析子宫内膜癌组织中BDNF、TrkB的表达与其临床病理特征的关系。结果：BDNF及TrkB在正常子宫内膜中呈阴性
或弱阳性表达，在增生子宫内膜及子宫内膜癌中呈阳性表达，三组间的差异存在统计学意义(P＜0.05)。子宫内膜癌中BDNF、TrkB
的表达与肿瘤细胞分化程度、临床病理分期、肌层浸润深度、淋巴结转移的有无均显著相关(P＜0.05)。结论：BDNF及其受体TrkB
的相互作用可能在子宫内膜癌的发生发展中起重要作用，二者联合检测可能对子宫内膜癌的术前病情评估及术后预后预测均具
有重要的参考意义。 |

| Objective:To observe the expressions of brain-derived neurotrophic factor (BDNF) and tyrosine kinase receptor B
(TrkB) in endometrial carcinoma, and analyze their clinical significances.Methods:The expression of BDNF and TrkB was tested in 11
cases of normal endometrium, 16 cases of hyperplasia endometrium and 31 cases of endometrial carcinoma by using
immunohistochemistry, and their relationship with the clinicopathological characteristics of endometrial carcinoma were analyzed.Results:BDNF and TrkB were negatively or weakly positively expressed in the normal endometrium, while they were positively
expressed in the hyperplasia endometrium and endometrial carcinoma, statistically significant differences were found between the three
groups (P＜0.05). The expression of BDNF and TrkB in endometrial carcinoma were significantly correlated with the tumor cell
differentiation, clinicopathologic staging, myometrial invasion and lymph node metastasis of endometrial carcinoma (P ＜0.05).Conclusion:The interaction of BDNF with TrkB may play an important role in the occurence and development of endometrial
carcinoma, so the combined detection of them may have important referent meanings for the preoperative condition assessment and
prognostic prediction of endometrial carcinoma. |
