胃癌单克隆抗体临床诊断应用及与CP相关性的探讨

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。     

Frequency of use and knowledge of the WHO-surgical checklist in Swiss hospitals: a cross-sectional online survey

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.

     

Predictors of the development of myocarditis or acute renal failure in patients with leptospirosis: An observational study

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.     

亮菌甲素速溶片剂的研制及其利胆作用研究

试制出亮菌甲素速溶片剂(A),并以市售品亮菌甲素片剂(B)、亮菌甲素粉针(C)等作对照,考察了它们对大鼠体内胆汁分泌作用的影响,并测定了A和B的体外溶出速率。结果表明,A片剂比B片剂明显地增强了利胆作用,A片的体外溶出速率也较B片为快。     

Musculoskeletal tumors: improved depiction with linear combinations of MR images

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.     

Regression of mediastinal Hodgkin disease after therapy: evaluation of time interval

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.
