肾上腺素对低温海水浸泡失血性休克大鼠血压的影响

目的:探讨肾上腺素对低温海水浸泡失血性休克大鼠平均动脉压和心率的影响及其机制。方法:成年雄性SD大鼠28只随机分为4组:正常组(N组,常温未作任何处理),肾上腺素组(E组,常温下失血性休克后注射肾上腺素),低温海水浸泡失血性休克+生理盐水组(DSN组),低温海水浸泡失血性休克+肾上腺素组(DSE组),每组7只,检测平均动脉压(MAP)和心率(HR)。结果:注射肾上腺素后,DSE组MAP前、中期高于正常组,末期迅速下降并低于正常组,但高于注射药物前的血压。E组血压发生了双向性变化。结论:低温海水浸泡失血性休克大鼠注射肾上腺素未能引起血压的双向性变化。

Metabolic profiling of plasma from cardiac surgical patients concurrently administered with tranexamic acid: DI-SPME–LC–MS analysis

A metabolic profile of plasma samples from patients undergoing heart surgery with the use of cardiopulmonary bypass (CPB) and concurrent administration of tranexamic acid was determined. Direct immersion solid phase microextraction (DI-SPME), a new sampling and sample preparation tool for metabolomics, was used in this study for the first time to investigate clinical samples. The results showed alteration of diverse compounds involved in different biochemical pathways. The most significant contribution in changes induced by surgery and applied pharmacotherapy was noticed in metabolic profile of lysophospholipids, triacylglycerols, mediators of platelet aggregation, and linoleic acid metabolites. Two cases of individual response to treatment were also reported.     

Immersion and distancing during assimilation of problematic experiences in a good-outcome case of emotion-focused therapy

Objective: Some studies have suggested that a decrease in immersion (egocentric perspective on personal experiences) and an increase in distancing (observer perspective on personal experiences) are associated with the resolution of clinical problems and positive outcome in psychotherapy for depression. To help clarify how this change in perspectives relates to clinical change, the present study compared changes in immersion and distancing across therapy with progress in one client’s assimilation of her problematic experiences. Method: We analyzed all passages referring to the central problematic experience in a good-outcome case of emotion-focused therapy for depression using the Measure of Immersion and Distancing Speech and the Assimilation of Problematic Experiences Scale. Results: Results showed that immersion and distancing were associated with different stages of assimilation. Immersion was associated with stages of emerging awareness and clarification of the problem and in the application of new understandings to daily life. Distancing was associated with problem-solving and attaining insight. Conclusion: The decrease of immersion and increase of distancing associated with therapeutic improvement should not be taken as a recommendation to avoid immersion and encourage distancing. Immersion and distancing may work as coordinated aspects of the processes of psychotherapeutic change.     

Diagnostic and therapeutic applications of water-immersion colonoscopy

Colonoscopy techniques combining or replacing air insufflation with water infusion are becoming increasingly popular. They were originally designed to reduce colonic spasms, facilitate cecal intubation, and lower patient discomfort and the need for sedation. These maneuvers straighten the rectosigmoid colon and enable the colonoscope to be inserted deeply without causing looping of the colon. Water-immersion colonoscopy minimizes colonic distension and improves visibility by introducing a small amount of water. In addition, since pain during colonoscopy indicates risk of bowel perforation and sedation masks this important warning, this method has the potential to be the favored insertion technique because it promotes patient safety without sedation. Recently, this water-immersion method has not only been used for colonoscope insertion, but has also been applied to therapy for sigmoid volvulus, removal of lesions, lower gastrointestinal bleeding, and therapeutic diagnosis of abnormal bowel morphology and irritable bowel syndrome. Although a larger sample size and prospective head-to-head-designed studies will be needed, this review focuses on the usefulness of water-immersion colonoscopy for diagnostic and therapeutic applications.
