Potential contribution of nuclear factor-kappaB to cerebral vasospasm after experimental subarachnoid hemorrhage in rabbits.

Nuclear factor-kappaB (NF-kappaB) plays a key role in inflammation, which is involved in the development of cerebral vasospasm after subarachnoid hemorrhage (SAH). In the present study, we assessed the potential role of NF-kappaB in regulation of cerebral vasospasm. Nuclear factor-kappaB DNA-binding activity was measured in cultured vascular smooth muscle cells (VSMCs) treated with hemolysate and pyrrolidine dithiocarbamate (PDTC, 80 micromol/L), an inhibitor of NF-kappaB. Forty-two rabbits were divided into three groups: control, SAH, and PDTC groups (n=14 for each group). The caliber of the basilar artery was evaluated. Nuclear factor-kappaB DNA-binding activity and the gene expression levels of cytokines and adhesion molecules in the basilar artery were measured. Immunohistochemical study was performed to assess the expression and localization of tumor necrosis factor (TNF)-alpha, intercellular adhesion molecule (ICAM)-1, and myeloperoxidase (MPO). It was observed that NF-kappaB DNA-binding activity was significantly increased by treatment with hemolysate in cultured VSCMs, but this increase was suppressed by pretreatment with PDTC. Severe vasospasm was observed in the SAH group, which was attenuated in the PDTC group. Subarachnoid hemorrhage could induce increases of NF-kappaB DNA-binding activity and the gene expression levels of TNF-alpha, interleukin (IL)-1 beta, ICAM-1, and vascular cell adhesion molecule (VCAM)-1, which were reduced in the PDTC group. Immunohistochemical study demonstrated that the expression levels of TNF-alpha, ICAM-1, and MPO were all increased in the SAH group, but these increases were attenuated in the PDTC group. Our results suggest that NF-kappaB is activated in the arterial wall after SAH, which potentially leads to vasospasm development through induction of inflammatory response.     

103例流行性出血热患者的心电图及心肌酶学分析

目的了解流行性出血热病毒(EHFV)对心脏的损害情况。方法对103例流行性出血热(EHF)患者的心电图及心肌酶学检测结果进行分析。结果72例(69.9%)患者出现心电图异常,以窦性心动过缓(27.9%)及窦性心动过速(22.3%)最常见,明显高于其它类型的心电图改变(P分别<0.05和0.001)。103例流行性出血热(EHF)患者的CK、LDH及HBDH的升高者分别为43例(41.2%)、73例(70.9%)及46例(44.7%),以LDH异常最常见。轻型、中型、重型及危重型流行性出血热患者的LDH值分别为(346.3±155.6)IU/L、(330.7±130.7)IU/L、(1114.4±872.4)IU/L及(1227.1±936.7)IU/L,经统计学处理重型及危重型的值与轻型、中型比较均有显著性或高度显者性差异。结论EHF患者并发心肌损害较普遍,而且病情愈重者,心肌损害愈严重。     

家庭护理的危险因素分析及对策

随着人们法制观念的增强,对自身合法权益的维护越来越重视,对医疗护理质量的需求也越来越高。近年来,人民生活水平的不断提高,患心脑血管疾病、肿瘤等慢性疾病者增多,护理需求量增加,需要护理人员从医院走向社区,走入家庭,为个人、家庭、社会提供直接、连续、全面、方便、快捷、经济、优质的家庭护理服务,以满足社区居民的需求。我院于2002年5月开设了家庭护理,现已开展了12项服务内容,共对27例病人(149例次)实施家庭护理服务,护理服务对象平均年龄为74.8岁,其中脑梗死23例,多伴有偏瘫、失语,合并有高血压、糖尿病等疾病;恶性肿瘤2例;肾衰竭…     

南京地区23例成人非何杰金淋巴瘤免疫病理分析

Histochemical study of colorectal adenocarcinoma by fluorescein isothiocyanate (FITC) conjugated lectins

Binding of FITC conjugated lectins to mucin in benign and malignant colon lesions was studied by fluorescence microscopy. In 145 cases of colonic adenocarcinoma, PNA (peanut agglutinin) was found to be bound to 75% of cases, while DBA (dolichos biflorus agglutinin) to 13% only. By contrast, DBA was bound to 94% of normal colon mucosa, while PNA to 15% only. Chronic colitis, simple adenoma and inflammatory polyps had the same binding pattern as normal mucosa, but villous adenoma, mixed polyps and multiple polyposis which are considered as premalignant lesions in colon had high positive rate of PNA binding and low binding percentage of DBA. These results indicate that an exposed carbohydrate structure Gal B1-2----GlNAc is expressed in the mucin produced by colonic adenocarcinoma. Meanwhile, some normal mucin component disappears from the malignant colonic epithelium. The mechanism of alteration of human colonic mucin present in malignant transformation is briefly discussed.
