立体定向放射治疗肺癌脑转移的疗效观察及护理(英文)

Objective: To observe the efficacy of stereotactic radiotherapy (SRT) in lung cancer patients with brain metas-tases and explore the nursing for those patients. Methods: From June 2002 to December 2006, 43 patients of lung cancer with brain metastases were treated with SRT, 8 of them were treated with the association of whole-brain radiotherapy (WBRT) and 6 of them were treated with combination of chemotherapy. During the period of SRT, the patients were applied with active psychological nursing and diet nursing. We also tried to prevent patients from epicranium injury, and meanwhile, patients were asked to took active convalesce exercise. Results: All patients finished SRT without serious reaction and complication. Local control rate was 81.4%, nervous system symptoms relief rate was 76.7% and KPS score was raised significantly. Survival time ranged from 2 to 34 months, median survival time was 8.5 months, and 6-month, 1-and 2-year survival rates were 58.9%, 26.2%, and 6.0% respectively. Conclusion: SRT was one of the effective palliation treatments for the lung cancer patients with brain metastases, and with the assistance of effective nursing, which would prolong their survival time and improved quality of life.

脑部恶性肿瘤组织切片的红外光谱研究

目的：探讨脑部恶性肿瘤细胞和正常细胞组织。方法：利用Ｆｏｕｒｉｅｒ红外光谱仪在室温下对１０例脑部恶性胶质细胞瘤（Ⅱ级）、１例正常组织切片进行微区红外透射光谱测量。结果：发现被测的１０例恶性胶质细胞瘤都具有相同的光谱特征，而较正常组织的光谱曲线具有明显的区别。实验发现脑部恶性胶质细胞瘤光谱中位于 １０８０ｃｍ－１吸收带增强、以及位于 １３７５ｃｍ－１、１４６２ ｃｍ－１和 １４７５ｃｍ－１的吸收峰明显增强的现象。结论：由于肿瘤细胞的异型性、形态、结构变异而导致的异常吸收特征。

对抗中风

什么是中风 中风指部分脑部细胞因脑部动脉“闭塞”或“爆裂”，脑细胞因得不到营养及氧气而死去。

帕金森病中关键致病因子α突触核蛋白的研究进展

帕金森病（PD）是中老年常见的慢性神经系统变性疾病，患病率和致残率均较高，是危害老年人健康的主要疾病之一。α突触核蛋白（α-Syn）的突变和异常聚集与PD的发生、发展密切相关，但尚未明确其致病机制。α-Syn是可溶性小分子蛋白，主要集中在脑部神经细胞中表达，
