碘盐预防碘缺乏病效果的系统评价

目的 系统评价碘盐预防碘缺乏病的效果.方法 计算机检索Cochrane Central Register of Controlled Trial(Cochrane图书馆2009年第4期)、MEDLINE(1966～2009.12)、Ovid Medline(1966～2009.12)、Embase数据库(1986～2009.12)、CBM光盘版(1978～2009.12)、CNKI(1980～2009.12)以及VIP(1989～2009.12),并且追查纳入文献的参考文献.按纳入和排除标准由2名评价者独立选择试验、提取资料,交叉核对并进行方法学质量评估,对同质研究采用RevMan 5.0软件进行Meta分析.结果 共纳入5篇随机对照研究,842例研究对象,儿童组碘盐和空白食盐的甲肿率结果比较无统计学意义[OR=1.19,95%CI(0.74,1.92)],成人组碘盐和其他形式的补碘措施比较,碘盐组甲肿率、甲状腺体积均低于其他形式的补碘组.结论 碘盐能显著改善成人的碘营养状况,副作用还需大量高质量的随机对照试验来验证.     

清开灵注射液治疗脑血管性痴呆32例

目的观察清开灵注射液治疗脑血管性痴呆的疗效.方法将中医学辨证属于实证的64例脑血管性痴呆患者随机分为治疗组(清开灵注射液组)和对照组(脑复康组),治疗5周后,将两组治疗前后在智力障碍程度、肢体功能、血液流变学指标、中医证型疗效方面的变化进行比较.结果经治疗后治疗组和对照组相比较,智力障碍程度变化(有效率、MMSE、ADL积分)、肌力、步行能力改变有显著性差异,p＜0.05.而治疗前后组内及组间血流变指标虽有一定下降,但无统计学意义(p＞0.05).结论清开灵注射液对脑血管性痴呆患者,在改善智力障碍、肌力、步行能力方面有较好的疗效.     

富含血管的听神经瘤

目的探讨富含血管的听神经瘤的手术治疗。方法复习20年（1975—1995）手术治疗单侧听神经瘤90例，其中4例为富含血管的听神经瘤（HAT），与86例非富含血管的听神经瘤（NHAT），做回顾性分析，据临床表现、放射学检查、手术所见做比较。结果HAT较NHAT年轻（28±10与54±17岁）（P〈0．01），MRI显示HAT为实质性，无肿瘤囊变，多数较NHAT为大（P〈0．05）；MRI示HAT有多个代表较大引流静脉的流空效应；经皮股动脉、椎动脉造影显示HAT有广泛的肿瘤着色及早期引流静脉的充盈，并证实由椎基动脉供血。过去文献报道认为以分期手术为宜。作者在控制性低血压麻醉下，成功地完成了4例HAT的切除术，未输血，术后无明显伤残。结论HAT是一种实质性大型肿瘤，出现于青年期，血管造影能够提供特征性发现。MRI能显示肿瘤表面的流空效应而确诊。采用控制性低血压麻醉有望能一期全切除肿瘤。     

Pituitary adenomas: Trans‐sphenoidal experience of 300 cases

Objective: The main aim of the present study was to examine the effectiveness and complication rate of the 1 cm right‐sided unilateral sublabial trans‐sphenoidal surgery for patients with pituitary adenoma equal to or greater than 5 mm in diameter. Method: A total of 350 patients were surgically treated for pituitary adenomas between December 1999 and December 2003 in an academic neurosurgical unit in China. Three hundred patients (86%) were treated with the 1‐cm right‐sided unilateral sublabial trans‐sphenoidal approach. The mean age of patients was 43 years (range 10–78 years) and female patients accounted for 59% of the total. One hundred and ninety‐six (64%) patients had functioning endocrine tumours and 104 (36%) patients had non‐functioning tumours or macroadenomas. Tumours which were outside this simple and basic classification were excluded from the study. Results: There were no operative mortalities. One patient developed hypopituitarism and 16 (5%) developed transient diabetes insipidus that required pituitrin treatment. The remission rate for macroadenoma was 85% and that for microadenoma was 98.5% during a medium term follow‐up of 1–5 years. One hundred and fifteen patients had prolactin secreting tumours and 90.4% achieved endocrine remission. Fifty‐six patients had growth hormone secreting tumours and 75.4% achieved endocrine remission. Preoperatively, one hundred and fifty‐one patients presented with visual impairment and 148 (98%) achieved a documented improvement in visual acuity. The mean duration of hospital stay was 4 days (range 3–7 days). Conclusion: This minimally invasive trans‐sphenoidal surgery for pituitary adenomas could be used as the primary treatment for small pituitary tumours. The effectiveness of the tumour removal and low morbidity rate compare favourably with the conventional sublabial approach as well as the more recently developed endoscopic endonasal approaches.     

Liver and lung resection for colorectal metastasis

Aim: To examine the survival benefit of liver and lung resection for colorectal metastasis and the potential prognostic factors that affect patient survival. Methods: All patients who had resection of lung or liver metastasis for colorectal metastasis in Queen Elizabeth Hospital, Hong Kong from 1995 to 2004 were retrospectively reviewed. The overall and disease‐free survival was analysed, in particularly between liver and lung metastasis. All factors that may have affected the survival were entered into Cox's proportional hazards regression model to identify significant variables associated with survival. Results: At 5 years, the overall survival of patients who had resection of lung and liver metastasis was 44% and 38%, respectively; the disease‐free survival was 26% and 24%, respectively. Overall and disease‐free survival of patients with resection of lung metastasis was comparable to those with resection of liver metastasis. The differentiations of primary tumour and time to metastasis were shown to be significant prognostic factors influencing overall survival. Those patients with systemic chemotherapy after resection of colorectal metastasis demonstrated a significantly higher probability of overall survival. Conclusion: Resection of lung and liver metastases from colorectal origin was safe and both procedures improved survival. The use of chemotherapy after resection of metastasis significantly improved the overall survival.
