宫腔镜双极汽化电切术临床分析

目的 探讨宫腔镜双极汽化切割术的安全性和疗效。方法 术前宫腔镜诊断均为黏膜下肌瘤和肌壁间凸向宫腔肌瘤36例，在宫腔镜下施行双极汽化电切术。结果 手术成功率100％，手术时间10-70分钟，平均32分钟；出血量12-100ml，平均28ml；标本重15-42g，平均31g。术中、术后无并发症。术后满意率94．4％。结论 宫腔镜双极汽化切割术具有手术时间短、出血少、无并发症等优点，疗效满意。     

原发性肝癌患者肝切除术前、后免疫细胞表型分析

目的研究原发性肝癌(PrimaryLiverCarcinoma,PLC)患者肝切除术前、后免疫细胞表型的变化。方法采用直接免疫荧光标记,流量血细胞计数法(FlowCytometry,FCM)检测方法,动态观察120例PLC患者肝切除术前后外周血T淋巴细胞亚群、NK细胞和HLA鄄DR含量变化。结果肝切除术前肝功能Child鄄PughB级、OGTTL型和术前施行肝动脉栓塞化疗患者外周血CD8+T细胞含量明显低于正常人组,CD4+/CD8+比值则较高(P<0郾05)。全部肝癌患者肝切除术前、后CD3+CD4+T细胞和NK细胞(CD3-CD16+CD56+)含量无明显差异。术后第1天、第3天、第7天和第2周外周血淋巴细胞CD3+CD8+含量明显低于肝切除术前和术后第3周(P<0.01);而CD4+/CD8+比值则显著高于肝切除术前和术后第3周(P<0郾01)。结论PLC合并肝硬变肝储备功能不足、术前肝动脉栓塞化疗和肝切除术可导致机体细胞免疫功能低下,PLC患者肝切除术前行肝动脉栓塞化疗的价值有待深入研究。     

临床护士工作满意度调查及分析

目的 探讨护士工作满意度状况及其影响因素.方法 应用Mueller/McCloskey满意度量表(MMSS)对随机抽取的574名护士进行问卷调查,并对结果进行分析.结果 护士对自己工作总体满意程度不高,为(2.95±0.49)分;对工作待遇的满意度最低为(2.10±0.71)分.不同年龄、学历水平护士的工作满意程度比较差异有统计学意义,P＜0.05.结论 应根据影响工作满意度因素采取不同的管理措施及激励手段,提高护士的工作满意度.     

SOME ANATOMICAL DATA RELATED TO THE TRANSNASO- SPHENOIDAL RESECTION OF PITUITARY FOSSA TUMORS

Since the beginning of this century, trans- naso-sphenoidal resection of the pituitary fossa tumors has been widely used clinically. It has more merits than other operative approaches used before. In China it has been adopted by both ENT doctors and neurosurgeons since 1959.1 In order to afford some relevant anatomical data, we measured 137 adult sagittal plane skulls with distinct landmarks.     

An intracellular self protein synthesized in macrophages is presented but fails to induce tolerance

Mice deficient for the fifth component of murine complement (C5), unlike normal mice, do not possess the secreted form of C5 in their body fluids and can be readily immunized to serum-derived normal C5. Although macrophages from C5-deficient mice do not secrete C5, they synthesize the precursor form (pro-C5). Therefore contact of T cells with autologous pro-C5 presented by macrophages is theoretically possible. We show that macrophages from C5-deficient mice can indeed stimulate a class II restricted C5-specific T cell clone without addition of exogenous C5. Immunization of C5-deficient mice with autologous pro-C5 induces vigorous C5-specific T cell proliferation and pro-C5 is recognized by C5-specific T cells in vitro, demonstrating that this protein fails to induce tolerance under physiological conditions. Thus, intracellular pro-C5 is processed and presented by C5-deficient macrophages and can activate T cell clones in vitro, yet is neither immunogenic nor tolerogenic for T cells in vivo.     

基于临床流程功能需求的生理监测仪配置评估

病人生理监测仪是临床医学的主要仪器之一，由于所涉及的技术流程定位不同，功能需求也就不同，其功能配置也应有所不同。本文从分解分析生理监测仪相关应用领域的技术定位功能需求出发，讨论卫生技术装备管理的功能配置评估。
