洁净手术部病理标本的管理

医疗标本是指用来化验或研究的血液、痰液,组织切片等[1]。我院于2006年1月正式启用洁净手术部。洁净手术部管理的目标是杜绝事故,减少差错,确保病人手术安全,其中病理标本的管理是最重要的项目之一。根据洁净手术部严格分区管理的特色,对日常工作中的病理标本管理在控制污染,严禁标本混淆、丢失、及时送检4个方面进行严格规范,取得了满意的效果。现介绍如下。1存在的问题1.1容易扩散污染手术结束后,手术医生穿着带有血渍的手术衣、手套到标本室填写病理检查单,接取保存液,再返回手术间处理手术后事宜,容易造成污染和血液传染性疾病的发生。…     

冷敷在重睑成形术中的应用效果观察

重睑成形术是眼睑美容手术之一。随着人民生活水平的提高,要求美容的人也越来越多[1]。由于该手术大部分需要切开剥离,去除眼轮匝肌或去脂去皮,容易引起皮下组织水肿、淤血,影响恢复和术后效果。2005年11月—2006年11月,笔者对124例重睑受术者进行术中冰生理盐水冷敷,在减轻水肿、淤血程度、缩短恢复期方面疗效显著。现报道如下。1资料与方法1.1临床资料本组共124例,其中女118例,男6例,年龄20岁～58岁。将受术者按手术时间先后顺序随机分为实验组和对照组各62例。1.2方法两组均使用电凝止血,5-0丝线缝合后用无菌纱布包扎伤口,口服5d抗生素。…     

Experimental study on the immunosuppressive effects of gui zhi tang

In this paper the immunosuppressive effects of Gui Zhi Tang (a famous Chinese medicine) on the murine immune functions are reported. Varying dosages of Gui Zhi Tang administrated orally, i.p. and i.m. were able to inhibit the amounts of PFC, SRFC and the DTH response induced by BSA and the proliferation response of murine spleen cells to Con A and LPS. Further studies showed that Gui Zhi Tang had the inhibitory effect on Interleukin-2 production of murine spleen cells, which might be one of the mechanisms leading to the immunosuppressive effects of Gui Zhi Tang.     

Expression of CD68 CD45RO CD20 and proliferating cell nuclear antigen in nasal polyps]

OBJECTIVE: To study the cellular expression of CD45RO, CD20, CD68 and proliferating cell nuclear antigen (PCNA) in nasal polyps. METHODS: Nasal polyp tissues from 50 patients were evaluated for cellular expression of CD45RO, CD20, CD68 and PCNA using immunohistochemistry SP by counting the average number in 5 chosen high-power fields, Histopathological observations were combined with HE. Analyses were performed on SPSS10.0. RESULTS: CD68+ cells were expressed more in nasal polyps dominated by eosinophils than by neutrophils(P < 0.05). There was no difference between CD45RO and CD20, but both of them had negative correlation(P = 0.05). Significant correlation was found between CD68+ cells and eosinophils or PCNA positive cells on epithelium. PCNA positive cells on epithelium had significant correlation on fibroblast (P < 0.05). CONCLUSION: Inflammatory cell infiltration (eosinophilia CD45RO, CD20, CD68) and cell proliferating in epithelium cells, glandular cell and fibroblast are strongly correlated with formation of nasal polyps. The nasal polyps are not only characteristic of eosinophilia but also by lymphocytes dominated by CD45RO and CD68 positive cells. CD68 may be stem cell of nasal polyp.
