立体定向分次放疗联合全脑放射治疗脑转移瘤疗效分析

Objective To evaluate efficiency of brain metastases tumor using X-knife under farctionational stereotactie radiotherapy (FSRT) combine with whole brain radiotherapy (WBRT). Methods Retrospective comparing 51 patients treated by FSRT plus WBRT (FSRT + WBRT group) with 35 patients treated by WBRT alone (WBRT group) on the effecting rate and survival rate. Results The completeness response rate was 49 % and 26 % (P < 0.05) in FSRT + WBRT and WBRT groups, respectively. The effecting rate was 80 % and 71 % (P 0.05) in FSRT + WBRT and WBRT groups, respectively. The middle survival time was (11.0 ± 1.5) months and (6.5 ± 0.5) months (P < 0.05) in FSRT + WBRT and WBRT groups, respeetivley. The 0.5-, 1.0- and 1.5-years survival rate was 63 % and 41 % (P 0.05), 51 % and 23 % (P 0.05) and 24 % and 9 % (P < 0.05) in FSRT + WBRT and WBRT groups, respectively. Conclusions The method with FSRT plus WBRT in the treatment of brain metastases tumor is safe and relieved focal symptom of patients quickly with lesser injury on normal tissue and the survival time be prolonged, it has better therapeutic effects than WBRT alone for treating brain metastases tumor.     

低场MR肾动脉三维增强血管成像对肾动脉疾病的诊断价值

目的探讨低场MR三维增强血管成像（3D CE-MRA）显示肾动脉及病变的临床诊断价值。方法对25例肾脏移植供肾者及临床疑有肾动脉狭窄者行低场MR 3DCE-MRA检查,图像后处理用最大信号强度投影法（MIP）重建,并与临床手术及DSA检查相对照。图像质量采用优、良、差3级评价。结果25例55条肾动脉均显示清晰、图象质量均达到优,其中正常肾动脉50条,狭窄肾动脉5条,与手术及DSA比较诊断符合率为96%。结论低场3DCE-MRA作为新的无创伤血管成像技术,成像效果好,对正常肾动脉能清晰显示,对肾动脉狭窄及程度能准确地判断,具有重要的临床价值。     

生脉注射液防治放射性心脏损伤疗效观察

目的：观察生脉注射液对放射心脏损伤的防治疗效．方法：确诊为胸部恶性肿瘤者71例，随机分为治疗组和对照组．治疗组37例放疗全程应用生脉注射液40—60ml＋5％葡萄糖注射液250ml静脉点滴，每天一次．对照组34例放疗开始后两周应用强的松40mg每天一次，晨服，2周为1疗程．两组放疗累积生物剂量至DT60—70Gy．结果：放疗后比较生脉注射液组心电图异常及酶学变化明显低于对照组（P〈0．05），且放疗前后比较生脉组差异无显著性而对照组差异有显著性（P〈0．05）．心脏形态改变生脉组与对照组比较差异有显著性（P〈0．05）．结论：生脉注射液可降低心脏的放射损伤反应，安全无明显毒副反应，可作胸部肿瘤放疗时为防治放射性心脏损伤的一种方法用于临床．     

低场MRI在主动脉夹层诊断中的临床应用

目的评价MRI在诊断主动脉夹层诊断中的价值。方法回顾性分析我院30例主动脉夹层的MRI表现。结果30例按Debakey分型分为:Ⅰ型8例,Ⅱ型8例,Ⅲ型14例。30例均显示真假两腔及内膜片,24例显示破裂口,16例显示有附壁血栓。结论MRI是诊断主动脉夹层首选的无创性影像学检查方法,对临床治疗主动脉夹层有着非常重要的意义。
