OBJECTIVE To investigate the prognostic value of measuring Ki67 and VEGF expression in laryngeal squamous cell carcinoma (LSCC).METHODS The expression of Ki67 and VEGF in 32 LSCC tissues was studied by immunohistochemical staining. Of these cases, 5 recurred (recurrent group), 3 cases metastasized (metastatic group), 8 cases died (deceased group) and 24 cased survived (survival group) over a 3 year period of follow-up after their operation.RESULTS The expression of Ki67 and VEGF in the deceased group was higher compared to that in the survival group (P＜0.01). Overexpression of Ki67 was found in the recurrent group and in the metastatic group (P＜0.05). VEGF expression was higher in the recurrent group than in the non recurrent group (P＜0.05). With Cox-regression of multivariate analysis,Ki67 (RR:3.236; P=0.001), the clinical T stage (RR:1.382; P=0.029) and metastasis in lymph nodes (RR:0.316; P=0.033) were shown to be independent prognostic factors for survival of LSCC patients.CONCLUSION Ki67 and VEGF expression is related to the prognosis of LSCC. Overexpression of the 2 markers indicated poor prognosis of the disease, a finding which might be helpful for the treatment of laryngocarcinoma.

分析了工位送风在空间站的适用性,确定了评价指标。建立了物理模型和数学模型,分析了不同工位送风量和送风速度对舱内乘员工位区空气质量的影响,得到了CO2浓度、空气龄、空气新鲜度比、局部换气效率和工位区风速分布,同时与无工位送风进行了对比。结果表明,工位送风在较小风量时就可以满足空气质量要求,符合航天器轻量化原则;在相同总风量下加大工位送风量后,工位区的性能指标均有所改善;在工位送风量一定情况下,送风速

中央电视台CCTV主楼两个塔身双向倾斜、高位超大悬臂的建筑造型特征使得结构根部产生显著倾覆弯矩,并产生基础不均匀沉降。为保证施工方案的顺利实施并监控基础的安全性,采用静力水准方法每日监测关键测控点的相对沉降;并用光学水准对整个基础沉降进行定期、全面测量。两种监测方法有机结合,有效和准确地反映了基础沉降变化过程及基础变形规律,施工期间整个基础沉降量小、两个塔身基础倾斜值在规范限值范围内。
