Pulmonary Function in Survivors of Wilms' Tumor

The respiratory status of 47 patients surviving childhood Wilms' tumor was studied. The group that had receivedflnnk irradiation (which impinges on the lower lung) (n - 17) had a sisnijGantly lower mean percent predicted for forced expiratory volume in one second, residual volume, and total lung capaci(v when compared to those who had received no irradiation (n - 23). Those patients who had received whole-lung irradiation (n - 3) had sisnijicantly lower transfn. foctor for carbon monoxide and gas transfer per unit lung volume whm compared to the nonirradiated group (n - 23). There was no sipiftiant dimue in the prevalence of respiratory symptoms between the three groups. Patients receiving any form of radiotherapy for Wilms' tumor may have abnormulities o f pulmonary function and should have pulmonary function tests performed as part o f their long-tmn follow-up.     

神经导航辅助显微手术治疗脑功能区肿瘤

目的探讨神经导航系统辅助下脑重要功能区肿瘤显微手术的治疗效果和应用价值。方法1999年12月～2002年6月应用StealthStation神经导航系统辅助切除邻近脑重要功能区肿瘤10例,对神经导航系统术中应用的优越性、精确性等进行分析。结果本组平均注册误差为(2.8±0.9)mm,肿瘤和重要解剖功能结构定位准确,肿瘤全切除率77.8%。术后神经功能未受明显影响,无手术并发症及死亡。结论神经导航系统对于切除邻近脑重要功能区肿瘤具有定位准确,动态示踪和实时导航,侵袭性小,安全、可靠等特点,有助于提高肿瘤全切率及降低手术并发症。     

氮芥抗药性人早幼粒白血病HL60细胞亚系的建立及其生物特性

用逐步递增药物浓度和软琼脂细胞克隆技术，药物连续作用１４个月后获得氮芥（ＨＮ２）抗药性人早幼粒白血病ＨＬ６０细胞亚系，抗件达５～７倍（ＨＬ６０／ＮＨ２６），在无ＨＮ２培养液中５倍以上抗性维持１０个月以上，抗性细胞亚系的生物学特性除倍增时间稍长和克隆形成率略低外其生长曲线，细胞周期细胞ＤＮＡ指数，形态学，组织化学和染色体分析均与亲代细胞相似。     

假性胰腺囊肿的内窥镜治疗

目的 探讨假性胰腺囊肿内窥镜治疗的适应证、手术效果、并发症及优缺点。方法 对假性胰腺囊肿内窥镜治疗的相关文献进行综述。结果 内窥镜技术具有创伤小、操作方便、可反复进行等特点，其适应证正不断扩大．除内窥镜治疗失败、囊肿合并并发症和多发性囊肿时考虑外科手术外，其他情况下假性胰腺囊肿的治疗可考虑内窥镜优先的策略。结论 假性胰腺囊肿的治疗应根据囊肿大小、数量、解剖学部位及有无并发症等综合因素实行个体化原则。     

Analysis on Mental Features and Nursing Countermeasures for Malignant Ovarian Tumor Patients

Objective To inquire into the mental features of malignant ovarian tumor patients and advance the way to appease the mental state. Methods The mental health status of 168 malignant ovarian tumor patients was evaluated using Symptom Checklist 90 （SCL-90）, and compared with that of normal crowd and other gynecologic malignant tumor patients. Results The scores of suppression, anxiety, fear, somatization, constrain, hostility, interpersonal relationship of the ovary malignant tumor patients were higher than those of the normal model, and the scores of suppression, anxiety, interpersonal relationship higher than those of other gynecologic malignant tumor patients. Conclusions To strengthen the nursing teaching, understand the mental state on time, use moral support therapy, and help the patients to change their inadequate attitude and behavior, can strengthen the therapy confidence and promote the health rehabilitation.     

Rhabdomyoma of the heart with intrapericardial expansion

A rare case of a rhabdomyoma originating from the surface of the right atrium in a 20-year-old female is reported. The tumor showed electrical activity and caused both outflow obstruction and tamponade symptoms. It was successfully removed by a right-sided thoracotomy. The clinical course, diagnostic investigations, and the therapeutical approach of this rare lesion are discussed.     

Free amino acid pattern of cerebrospinal fluid in meningeal pathology

Free amino acid concentrations of CSF were measured in bacterial meningitis, aseptic meningitis, meningoradiculitis Garin-Bujadoux-Bannwarth, multiple sclerosis, carcinomatous meningitis, and controls. Almost all CSF amino acids were highly elevated in bacterial but not in aseptic meningitis, meningoradiculitis Garin-Bujadoux-Bannwarth or carcinomatous meningitis thus providing a laboratory tool for their differential diagnosis. In carcinomatous meningitis the amino acid pattern indicates metabolic activity of tumor cells. Minimal alterations were found in multiple sclerosis which have no diagnostic value.     

胸水CYFRA21-1、CEA及NSE联合测定对肺癌的诊断价值

目的　通过胸水CYFRA2 1 1(细胞角蛋白片段 )、CEA(癌胚抗原 )及NSE(神经烯醇化酶 )的检测 ,探讨各指标对肺癌诊断特异性及联合分析对肺癌的诊断价值和临床意义。方法　对 12 3例肺良性疾病组患者和 15 6例肺癌组患者胸水进行上述肿瘤标志物测定。将肺癌患者又根据病理类型分成腺癌组 (81例 )、鳞癌组 (5 0例 )、小细胞癌组 (12例 )和未定性癌组 (13例 )对各指标分别进行对照分析。结果　肺癌组胸水CYFRA2 1 1、CEA及NSE含量 (ng/ml)分别为 5 5 34± 37 44、5 7 11± 5 2 6 5及 16 99± 2 9 2 2 ,而肺良性疾病组的含量则分别为 9 0 8± 7 5 4、9 92± 6 2 8和 7 30±6 2 9,各指标的统计学检验均有极显著差异 (P <0 0 0 1)。CYFRA2 1 1在肺鳞癌组最高 ,与小细胞肺癌组相比有显著差异 (P <0 0 5 ) ,而与腺癌组和未定型癌组相比无显著差异 (P <0 0 5 ) ;CEA主要在腺癌组的含量均比其他肺癌组有极明显增高 (P <0 0 0 1) ;NSE则在小细胞癌组最高 ,其含量与其他肺癌组相比有极明显增加 (P <0 0 0 1)。结论　胸水CYFRA2 1 1,CEA及NSE在不同组织类型肺癌中的含量明显不同 ;三者联合测定对肺癌的诊断有重要的临床参考价值     

Intramedullary pilocytic astrocytomas — a clinical and morphological study after combined surgical and photon or neutron therapy

Ten patients suffering from intramedullary pilocytic astrocytomas (WHO-classification: astrocytoma grade I) were investigated catamnesticly. Combined surgery and radiotherapy was performed. Seven patients received neutron irradiation postoperatively. In four cases the neurological symptoms were improved after follow-up periods ranging from 33 to 89 months. The three other patients died after 6 to 21 months. The autopsy findings of a 14 year old child are presented. Our results are compared with reports in the literature. In addition, long-term problems of the spinal column are discussed. It seems that the combined surgical and neutron therapy improves the prognosis of pencil gliomas.
