目的研究胰岛素样生长因子(insulin like growth factor,IGF)在子宫内膜癌组织中的表达情况,并探讨IGF系统与子宫内膜癌发生之间的关系。方法选择子宫内膜癌患者30例和因良性疾病切除子宫的患者20例作为对照,选用Western Blot方法检测子宫内膜癌组织中胰岛素样生长因子受体-1(insulinlike growth factor receptor-1,IGF-1R)的水平。结果发现子宫内膜癌组织中IGF-1R的表达明显高于正常子宫内膜组织,且与分期密切相关。结论 IGF-1R在子宫内膜癌的发生发展中起着重要作用,其受体阻断剂的应用可能是一个有前景的治疗方法。

以无机铪溶液为前驱体,采用化学气相渗透法(CVI)和前驱体浸渍裂解法(PIP)制备密度为2.14 g/cm^(3)的C/C-HfC复合材料,分析其微观结构和组成,测试材料的抗烧蚀性能。结果表明:HfC陶瓷均匀地分散于基体的孔隙中,且与基体结合紧密。引入HfC陶瓷可以显著增强C/C复合材料的抗烧蚀性能。在相同的热流条件下,烧蚀时间为120 s时,C/C-HfC复合材料的线烧蚀率为6.20×10^(-2)mm·s^(-1),质量烧蚀率为2.03×10^(-2)g·s^(-1),分别比C/C复合材料降低了48.33%和40.12%。在烧蚀过程中,HfC会与热流中的氧气反应生成熔融的HfO_(2),均匀地覆盖在基体的表面形成保护层,隔绝热流,防止基体被氧化,同时阻止热量的传递。熔融HfO_(2)的蒸发也会带走表面的部分热量。随着烧蚀时间的增加,HfO_(2)的损耗会逐渐上升,基体表面的保护层会逐渐被破坏,热流对基体产生的烧蚀损伤会更为严重。
