[目的]观察比较异环磷酰胺(IFO)、顺铂(DDP)、5-氟尿嘧啶(5-Fu)联合方案(IPF方案)与DDP,5-Fu(PF方案)治疗晚期复发鼻咽癌(Ⅲ-Ⅳ期)的近期疗效及毒副反应。[方法]136例均经病理证实为晚期复发鼻咽癌患者,随机分为IPF组69例,PF组67例(对照组)[结果]IPF组和PF组有效率分别为69.56％(48/69)和43.3％(29/67),两组间差异有显著性(X2=8.519,P<0.01)。中位生存期:IPF组16个月(8-34个月),PF组为6.5个月(4-21个月),两组间差异有显著性(X2=22.36,P<0.05)。毒副作用主要为骨髓抑制,Ⅲ-Ⅳ度白细胞下降率IPF组为49.4％,PF组为5.97％,两组差异有显著性(X2=29.54,P<0.01)。Ⅲ-Ⅳ度血小板下降率IPF组为29.18％,PF组为0％(X2=30.29,P<0.01);Ⅲ-Ⅳ度消化道反应两组的发生率分别为15.94％和11.94％(x2=0.234,P>0.01).且以Ⅲ度为主。[结论]以IFO为主的方案联合治疗晚期复发鼻咽癌疗效好,毒副反应能耐受,可作为一线方案。     

奥兰扎平治疗精神分裂症58例临床观察

目的观察奥兰扎平治疗精神分裂症的临床疗效与安全性.方法选择58例精神分裂症病人,开始给予奥兰扎平5mg*d-1,3d后根据临床疗效、副反应情况酌情增加剂量,最大剂量不超过20mg*d-1,治疗8周.治疗前及治疗后每2周用PANSS、CGI、TESS量表评定1次.结果治疗后PANSS总分、各因子分较治疗前显著下降(P<0.01),副反应主要有抗胆碱症状、过度镇静、体重增加、一过性丙氨酸氨基转移酶升高.结论奥兰扎平是一种安全、有效、副作用较轻的抗精神病药.     

Management of pediatric pontine gliomas

We present 36 consecutive patients with intrinsic glioma of the pons. Tumors with exophytic expansion were excluded. There were 16 females and 20 males, ranging in age from 2 to 13 years, median 6 years. The most common presenting symptoms were cranial nerve dysfunction. unsteadiness of gait, and hemiparesis. Computed tomography (CT) showed a hypodense (17/21) or isodense (4/21) expansion of the pons. Five tumors had areas of contrast enhancement. Following information about prognosis and possible types of management, parents decided for or against radiation therapy: twentyfour children underwent irradiation and 12 did not. Median survival among children receiving a full course of irradiation was 280 days, compared to 140 days in an equivalent group of non-irradiated children. Hemiparesis presenting without cranial nerve symptoms and contrast enhancement on CT scan were poor prognostic factors, whereas sex, age, and duration of symptoms at diagnosis were unrelated to prognosis.     

TRH、EGF及地塞米松促进未成熟胎肺组织分化及表面活性物质合成的研究

目的 比较TRH、EGF与地塞米松对未成熟胎肺形态发育及表面活性物质水平的影响。方法 在兔妊娠第22－24d或第24－26d分别用TRH、EGF或地塞米松母体静脉注射治病，通过光镜、图像分析及电镜等技术观察胎肺的形态结构，并检测胎肺的磷脂水平。结果 光镜下，TRH、EGF与地塞米松治疗组第25d及27d胎肺肺泡腔、肺泡间隔发育均明显好于对照组；EGF、TRH与地塞米松治疗组第27d胎肺的肺泡腔与肺泡间隔的面积比无明显差异。但EGF和TRH治疗组第25d胎肺的肺泡腔与肺泡间隔之比明显小于地塞米松治疗组。电镜下，三个治疗组第27d胎肺内含有板层体的Ⅱ型上皮细胞数量明显多于对照组，但各治疗组及对照组第25d的胎肺Ⅱ型上皮细胞胞浆内几乎未见明显板层体，相反胞浆内糖原含量却非常丰富。此外，三个治疗组27d胎肺的磷脂水平均明显高于对照组。结论 EGF、TRH及地塞米松在兔妊娠第24－26d母体治疗均能促进胎肺的形态发育和表面活性物质的合成，三种治疗方法对胎肺的影响程序无明显不同；在妊娠第22－24d治疗，地塞米松对胎肺形态结构的促进作用较EGF和TRH更明显，但三者对Ⅱ型上皮细胞分化及表面活性物质的合成均无明显影响。     

Primary papillary serous cystadenocarcinoma of broad ligament

A rare case of an advanced primary broad ligament carcinoma is discussed, with a review of the literature regarding its incidence, presentation and management. This patient showed a complete response to adjuvant cisplatin-based chemotherapy following panhysterectomy and is presently without any evidence of disease, 15 months after completion of her treatment.     

The Treatment of Low Grade Cerebral Astrocytomas by Radiotherapy in Queensland

The records of 108 adult patients with supratentorial low grade astrocytoma presenting between 1/1/80 and 31/12/87 were examined for the following factors which might affect survival: patient age, extent of surgical resection, site of tumour, tumour grade, radiation field size and radiation dose. Univariate analysis showed that patient age, field size and radiation dose were significant prognostic factors, but with multivariate analysis only patient age and radiation field size were significant independent variables. It is possible that field size is a proxy variable for tumour size.     

非放射科护理人员医用放射线防护知识调查分析

目的：调查非放射科护理人员对医用放射线防护知识的掌握程度，并比较不同学历护理人员之间的差异，为提高临床护理人员的防护意识、制定具体防护措施提供理论依据。方法：采用自行设计的问卷对100名非放射科护理人员进行问卷调查．结果：非放射科护理人员对医用放射线防护知识缺乏，不同学历护理人员之间存在差异具有非常显著性（P〈0．05）。结论：对非放射科护理人员进行放射线防护知识普及势在必行，对保护患者及护理人员自身健康具有重要意义。
