脾切除治疗原发性骨髓纤维化适应证的探讨

目的：探讨脾切除治疗原发性骨髓纤维化的可行性及其效果。方法：回顾性分析我院2000年1月至2006年12月间收治的5例行脾切除治疗原发性骨髓纤维化的病人资料。结果：本组病人均行脾切除术，其中2例加行贲门周围血管离断术．术后发生脾窝积液1例，肺部感染1例。随访3月至5年，病人贫血状况、左上腹疼痛症状均得到缓解．生活质量得到改善。结论：脾切除对有适应证的原发性骨髓纤维化是可行的治疗手段，可明显改善病人的症状，提高生活质量。     

干燥综合征与病毒感染的关系研究进展

干燥综合征是一种以口眼干燥为特征,主要累及外分泌腺的弥漫性结缔组织病。其发病可能与病毒感染、遗传和性激素异常等多种因素有关,在这些因素的共同作用下,机体免疫异常,组织损伤。与该病关系较密切的病毒有EB病毒、丙型肝炎病毒、巨细胞病毒、反转录病毒等。病毒在干燥综合征的发病机制中可能起重要的作用。     

雌二醇对不同性质的乳腺原代细胞增殖影响的体外研究

目的了解在体外条件下不同浓度的雌二醇对不同性质的乳腺组织原代细胞增殖的影响。方法用胶原酶消化法获取乳腺癌患者的各类乳腺组织原代细胞，并用MTT法检测乳腺癌组织、癌旁组织和正常乳腺组织原代细胞在体外培养下，给予不同浓度雌二醇时细胞的生长增殖情况。结果雌激素在体外对雌激素受体（ER）表达阳性的乳腺癌组织及癌旁组织原代细胞有明显的刺激生长作用；对正常乳腺组织细胞的促生长作用相对较弱，而且与肿瘤组织的ER表达情况无关。结论当体内的雌二醇水平≥10μmol／L时，乳腺癌的发病风险和复发风险会显著增加。     

降纤酶对进展性缺血性脑卒中预防作用的探讨

目的探讨降纤酶对进展性缺血性脑卒中的预防作用.方法将起病在72 h内的203例脑梗塞患者随机分成降纤酶治疗组及常规治疗组.降纤酶组在常规治疗的基础上加用降纤酶,治疗前后检测血液流变学各项指标,同时对进展性缺血性脑卒中患者的神经功能缺损进行评分.结果降纤酶组10例发生进展性缺血性脑卒中,常规治疗组24例,两组比较有显著性差异(P＜0.05);降纤酶组发生的进展性脑卒中的进展的严重程度比常规治疗组轻(P＜0.01);近期预后较常规治疗组好(P＜0.05);降纤酶治疗能明显降低血液流变学各项指标.结论降纤酶治疗能降低进展性缺血性脑卒中发生率,有利于进展性缺血性脑卒中患者神经功能的恢复.     

血清α—L-岩藻糖苷酶（AFU）对原发性肝癌（PHC）的诊断意义

目的研究血清α-L-岩藻糖苷酶（AFU）对原发性肝癌的诊断意义。方法分别测定20例正常对照者、45例慢性乙型肝炎、40例肝硬化、50例转移性肝癌及35例原发性肝癌患者的血清AFU。结果原发性肝癌组的血清AFU浓度和阳性率显著高手其他各组。结论血清AFU对原发性肝癌的诊断有重要价值。     

支气管肺癌伴其它部位多原发癌的影像诊断(附25例报告)

经病理确诊的527例原发性支气管肺癌(PBC)(1972～1987)中,PBC伴其它部位多原发癌(MPC)25例(4.7％)。其中双原发肺癌(DPBC)、12例(2.3％),PBC伴消化道癌6例(1.14％)。25例中共有原发癌灶52个,其中2例为3原发癌;同期组6例(其中DPBC 4例),后期组19例(其中14例间隔3年以上,内2例分别间隔14年及25年)。组织类型相同者8例,不同者4例。 25例MPC特点如下:1.55岁以上20例(80％);2.24例(96％)第2原发癌为1980年后发现;3.第2原发癌为肺癌者23例(92％);4.双原发肺癌12例(48％)。上述特点说明80年代老年人中MPC,尤其是肺癌发病率增高。 本文着重对第2原发肺癌的影像学表现和鉴别诊断进行讨论。     

Primary malignant melanoma: a rare cause of mediastinal mass

A case of primary malignant melanoma in the mediastinum presenting as recurrent laryngeal nerve palsy is reported. Tissue biopsy at mediastinotomy yielded a diagnosis of malignant melanoma. The mass was fixed to the left aspect of the trachea and to the upper border of the left main bronchus and could not be removed surgically. Further extensive clinical and radiological investigations revealed no evidence of tumor elsewhere in the body.     

A Simple Nephelometric Method for Measuring the Progressive Motility and Collecting Motile Spermatozoa

A simple method for collection and measurement of the progressive motility of spermatozoa was developed. The procedure consists of the spectrophotometric measurement of the increase in optical absorbance produced by the upward migration of spermatozoa in a high density medium of Ficoll 400. The suspension containing migrated spermatozoa may be used as a purified population of uniformly motile and undamaged spermatozoa.     

福建省原发性肝癌遗传因素分析

为了探讨遗传因素与福建省原发性肝癌的关系,应用多种对照配对的病例对照研究方法,对100个原发性肝癌和200个对照家系进行了遗传流行病学分析。结果显示,原发性肝癌先证者一、二级亲属患病率明显高于对照组患病率,分离比为0.04146～0.08654,遗传度加权均值为63.52±4.22％。提示原发性肝癌系多基因遗传病,遗传易感性是原发性肝癌的危险因素之一,原发性肝癌的发生是遗传和环境多种因素共同作用的结果。     

Case Study of Institution-Building by Nurse Bertha Wright and Colleagues

Purpose: To illuminate the history of nurses' participation in institution-building in the early 1900s, using the Baby Hospital in Oakland, California (now called Children's Hospital Oakland) as a case.
Design: Historical research using a framework of women's history theory focused on the women who founded Oakland's Baby Hospital, 1910–1930.
Method: Data collection included studying original sources, archival material, and interviews. Data evaluation included external criticism for authenticity and genuineness, and internal criticism for accuracy and bias.
Findings: In 1912, nurse Bertha Wright and social worker Mabel Weed, with a circle of community women, including Jessica Peixotto and Jean Howard McDuffie, established the Baby Hospital. Their activism included home visits, education, research, publications, political lobbying, and state policy and program development. At the center of this activity, was the lifelong commitment of Wright and Weed, who created new definitions of family. With social changes in the late 1920s, the male Board of Directors seized control of the hospital, and relegated women to auxiliary roles.
Conclusions: Health and social issues of the United States at the turn of the century are still problematic as a new century approaches and pertain to maternal-child health, foster care, and immigration. Feminists, including nurses, have played a central role in creating solutions. Knowledge of some of their incredible effort has been lost, particularly nursing's history in the western United States.
