长期鼻饲患者并发症的预防护理

由于病种的特殊性,虽失去自己进食的能力,但仍具有消化吸收的功能,因此用鼻饲饮食来代替自食,用来维持影响身体内的电解质平衡,对于长期鼻饲的患者还会产生一定的并发症,这是我们工作中应该引起注意的,现就长期鼻饲患者有关并发症的预防护理体会如下。1临床资料1.1一般资料本组男3例,女2例,年龄25~56岁。其中前臂伴脑损伤1例,神志不清伴上肢损伤4例,住院3个月~1 a。1.2治疗根据患者相关病情遵医嘱给予要素饮食鼻饲,配合活血化淤药物静滴治疗。1.3留置时间与方法(1)留置时间:朱玉芹等[1]报道长期鼻饲患者每4周更换鼻饲管1次。(2)留置方法:妥…     

结节型十二指肠炎的内镜表现及其与幽门螺杆菌关系的分析

结节型十二指肠炎是一种内镜下具有特征性改变的十二指肠粘膜病变，多表现为红斑性结节，不同程度的充血、水肿。大致分为慢性十二指肠炎和活动性十二指肠炎。根据本院3年来的资料，分析其内镜表现及与幽门螺杆菌（Hp）的关系。     

大鼠肾上腺细胞经胶原凝胶三维培养后进行同种移植的实验研究

Objective To investigate a novel method of adrenocotical cells transplantation. Methods Adrenal glands of neonate rats were dissociated into adrenal cortical cells. Cells were cultured in self-made collagen type Ⅰ gel for one week, and then transplanted under the renal capsule of bilateral adrenalectomy mate rats. Blood samples were collected per week after surgery. Animals were sacrificed at the 8th week, and histological characteristics of the allografts, proliferation of transplanted cells, CYP11B1 and CYP11B2 expression as well as plasma aldosterone and corticosterone were observed. Results There were totally 15 rats receiving collagen gel transplantation, and 12 survived 8 weeks post-operation. The plasma cortocosterone level in collagen gel transplantation group was significantly higher than in adrenocortical cell transplantation group, and reached the normal level from 6th to 8th week, but the change in plasma aldosterone level in collagen gel transplantation group was similar to that of adrenocortical cell transplantation group. The adrenocortical cells cultured in gel grew well, and had a high proliferation rate. 95% of them were fasciculata cells which expressed CYP11B1, and the rest were glomerulosa cells which expressed CYP11B2. No inflammatory cell infiltration was observed. Conclusion The proliferation and function of adrenocortical cells could be promoted when they were cultured in collagen gel.     

PET在全麻机制研究中的应用

正电子发射计算机断层扫描(PET)是一种功能性影像诊断新技术，能够在体反映机体内的物质代谢、局部血流量、受体密度等理化特性的变化。近年来PET技术已开始应用于全麻机制的研究，并在全麻药物的中枢区域定位、相关受体的功能分析等方面显示出独特的应用价值。     

巧用Ⅱ型安尔碘清除残留的骨水泥

骨水泥是骨关节手术中常用的填充材料，搅拌后黏稠，凝固迅速，易附着于搅拌器皿及手术器械而不易除去，用器械强行刮除已干涸的骨水泥会造成碎屑飞溅，影响器械台面整洁，若在骨水泥尚未完全硬化时用0．2％的Ⅱ型安尔碘棉球擦拭，即可轻松快速彻底清洁手术用物上的骨水泥。此法简便快捷，对器械无损伤，对环境及患者无害，值得推广应用。

lgE有何生物学功能？

答：lgE在种系发生过程中出现最晚，含量最低。但在过敏性疾患病人血清中lgE含量可显著增高。lgE是亲细胞性抗体，能以其Fc段牢固地结合在肥大细胞、嗜碱性粒细胞和血管内皮细胞表面。从而使机体致敏。lgE与Ⅰ型变态反应的发生密切相关，它主要由位于鼻咽、扁桃体、支气管及胃肠道黏膜固有层中的浆细胞产生，这些部位通常正是变应原入侵和过敏反应好发的部位。
