目的:研究胃癌单克隆抗体的表达及临床意义。方法:用本室制备的对胃癌有较强特异性的McAbGMG1:1D1-2对151例内窥镜活检组织压印片进行免疫组织化学检查。结果:用本法检查组织印片中的癌细胞以及具有癌细胞相关抗原的癌前病变组织,特异性强,反应灵敏,结果可靠,结论:如果与内窥镜和常规病理学检查联合应用,会提高早期癌的检出率,本文还就抗人胃癌McAb与CP的相关性进行了初步探讨。 相似文献

Background
The WHO-surgical checklist is strongly recommended as a highly effective yet economically simple intervention to improve patient safety. Its use and potentially influential factors were investigated as little data exist on the current situation in Switzerland.Methods
A cross-sectional online survey with members (N?=?1378) of three Swiss professional associations of invasive health care professionals was conducted in German, French, and Italian. The survey assessed use of, knowledge of and satisfaction with the WHO-surgical checklist. T-Tests and ANOVA were conducted to test for differences between professional groups. Bivariate correlations were computed to test for associations between measures of knowledge and satisfaction.Results
1090 (79.1%) reported the use of a surgical checklist. 346 (25.1%) use the WHO-checklist, 532 (38.6%) use the Swiss Patient Safety Foundation recommendations to avoid Wrong Site Surgery, and 212 (15.7%) reported the use of other checklists. Satisfaction with checklist use was generally high (doctors: 71.9% satisfied, nurses: 60.8% satisfied) and knowledge was moderate depending on the use of the WHO-checklist. No association between measures of subjective and objective knowledge was found.Conclusions
Implementation of a surgical checklist remains an important task for health care institutions in Switzerland. Although checklist use is present in Switzerland on a regular basis, a substantial group of health care personnel still do not use a checklist as a routine. Influential factors and the associations among themselves need to be addressed in future studies in more detail.55.

Background
Leptospirosis has a varied clinical presentation with complications like myocarditis and acute renal failure. There are many predictors of severity and mortality including clinical and laboratory parameters. Early detection and treatment can reduce complications. Therefore recognizing the early predictors of the complications of leptospirosis is important in patient management. This study was aimed at determining the clinical and laboratory predictors of myocarditis or acute renal failure. 相似文献56.

With postprocessing, the authors produced a single hybrid image that combines the complementary information in conventional T1- and T2-weighted magnetic resonance (MR) images. A 1-T MR imager was used to produce T1- and T2-weighted images (repetition time, msec/echo time, msec: 500/30, 1,500/120) of patients with various primary bone tumors. Various weighted sums and differences of these images were then formed. Weighted subtraction allowed formation of hybrid images with high contrast between tumor and all adjacent normal tissues (muscle, fat, bone marrow), unlike the original T1- and T2-weighted images. Certain weighted sums of the acquired images simultaneously display the high signal-to-noise and clear anatomic detail of the T1-weighted technique along with the high contrast between extraosseous tumor and muscle of the T2-weighted image. A single hybrid MR image can contain useful characteristics both of T1- and T2-weighted images, making it easier for one to detect the extent of an abnormality. 相似文献

Ninety-one patients with Hodgkin disease of the upper torso who had mediastinal masses were studied to determine the frequency of residual mass and the time required for resolution or stabilization of the mass. In 72 of these patients, radiographs from sufficient intervals were available for determination of the rate of regression. In 62 patients (86%), the mediastinum returned to normal width within 11 months, regardless of the size of the mass. The mediastinum returned to normal in all but one patient with small masses. The intrathoracic relapse rate did not correlate with the regression time of the masses, but relapse occurred more than twice as often in patients with residual mediastinal widening. 相似文献
