卡托普利异氟醚联合预处理对心脏瓣膜置换术患者的心肌保护作用

探讨卡托普利与畀氟醚联合预处理对心肌缺血再灌注损伤的保护作用。选择100例瓣膜置换术患者分为五组,分别给以不同的药物预处理。观察各组心肌酶、心肌蛋白、炎症因子的变化,以及心脏复跳率和血管活性药物使用。结果显示,卡托普利与异氟醚联合处理组的心肌酶、心肌蛋白、炎症因子以及心脏复跳率和血管活性药物用量与其他三组相比有显著性差异（P〈0．05）。认为卡托普利延迟相或早期相复合异氟醚预处理对心脏瓣膜置换术患者的心肌缺血再灌注损伤均具有更强保护作用,并以卡托普利延迟相组为优。     

盐酸戊乙奎醚对心脏瓣膜置换术患者NF-κB表达的影响

为研究盐酸戊乙奎醚对心脏瓣膜置换术患者心肌NF-κB转录活性的影响,选取择期瓣膜置换术患者60例,随机分为对照组(C)、盐酸戊乙奎醚组1(P1)、盐酸戊乙奎醚组2(P2),每组20例.结果心肌缺血再灌注后,P1、P2组NF-κB的转录活性明显下降,可见盐酸戊乙奎醚可以抑制心肌NF-κB的激活,在一定程度上具有心肌保护作用.

心肌保护新靶点——线粒体钙激活钾通道研究进展

心肌缺血再灌注损伤与线粒体有密切的关系.其中,位于线粒体的钾通道受到了人们的广泛关注.除了已被许多研究证明的线粒体ATP敏感钾通道参与心肌缺血再灌注的保护作用外,近年来研究发现的线粒体内膜钙激活钾通道也参与心肌保护作用,而国内相关研究报道很少.本文拟就心肌细胞线粒体上的钙激活钾通道结构、生物学特性和心脏缺血再灌注中的心肌保护作用进行简要阐述.

瓜蒌皮与前列地尔预处理对心肌缺血再灌注的影响

探讨瓜蒌皮和前列地尔预处理对心肌缺血再灌注的作用机制.通过建立SD大鼠心肌缺血再灌注的模型,采用Tunel法检测组织样本细胞凋亡和免疫组化法检测bax,bcl-2,caspase-3的蛋白表达情况进行研究.结果显示,瓜蒌皮和前列地尔半剂量联合组的凋亡细胞数、Bax和caspase-3的蛋白表达量较其他各实验组均明显降低,Bcl-2的表达量升高,且有统计学意义(P＜0.05);瓜蒌皮单用药组也表现为凋亡细胞数、Bax和caspase-3的表达量降低,Bcl-2的表达量升高,但程度不如两组联合用药组.实验可以证明细胞凋亡发生在心肌缺血/再灌注损伤中,瓜蒌皮可对心肌缺血/再灌注起保护作用,并且与前列地尔联合后更有利于对心肌细胞的保护作用.

Experimentation with Group Techniques with Ego-Disturbed Mothers

Abstract

Psycho–educational groups (PEGs) have been shown to be a particularly effective form of treatment for patients classified under the rubric of severely and persistently mentally ill (SPMI). However, recent surveys suggest that certain professionals, such as nurses and clinical psychologists, called on to conduct these groups may have limited to no training. This study tested three methods (self–instructional, workshop, and workshop plus clinical supervision) designed to provide on-the-job training to practicing clinicians. Specifically, training was based on two manuals; one that operationalized the basic knowledge and skills needed to run an effective PEG and the second being a commonly used PEG program for symptom management targeted at SPMI patients. Eight nurses from four adult units at a state psychiatric hospital initially received self–instructional or workshop training and then conducted a 12–session symptom management PEG composed of four to five SPMI patients (e.g., schizophrenia, schizoaffective or major depression disorders). In a second wave of additional training, nurses received workshop training or clinical supervision and then conducted a second PEG. Differences between training methods were assessed by nurse– and patient–completed measures that tapped the knowledge and skills emphasized in the symptom management and PEG (nurses only) manuals. Results indicated limited support for the superiority of the workshop method on the nurse measures alone. Implications for training working professionals in group treatments and assessing outcomes with chronic SPMI patients are discussed.     

Factors associated with respite care use by families with a child with disabilities

This paper reviews the literature on respite care utilization, describes a respite care program in Arkansas, and reports on a study of utilization initiated by the Arkansas Division of Mental Health Services (DMHS). Among the 89 families qualifying for respite services, 70 consented to participate, and 66 were surveyed in a phone interview. Users (n=54) and non-users (n=12) were compared relative to a variety of staff, child, geographic, and budget differences. Also, respite use was examined relative, to the aforementioned variables based on level of use, (i.e., none, low, moderate, high). There were no differences in use according to age, the number of family members, family income, or needs of the child. A larger percentage of non-use and low use of respite care was evident among those families receiving Tax Equity Fiscal Responsibility Act (TEFRA) benefits. There were no significant differences between races related to perceived barriers to care. Differences in expectations/experiences with respite care among rural and urban groups were limited with rural respondents expressing, concern about travel/distance issues. Overall, the program as a whole received positive ratings by parents, and no clear factors were found to be related to non-use in the small sample (n=12) who did not take advantage of respite services.     

Go/no‐go procedure with compound stimuli with children with autism

The go/no‐go with compound stimuli is an alternative to matching‐to‐sample to produce conditional and emergent relations in adults. The aim of this study was to evaluate the effectiveness of this procedure with two children diagnosed with autism. We trained and tested participants to respond to conditional relations among arbitrary stimuli using the go/no‐go procedure. Both learned all the trained conditional relations without developing response bias or responding to no‐go trials. Participants demonstrated performance consistent with symmetry, but not equivalence.     

Working with families of adults with anorexia nervosa

The aim of this paper is to describe working with the carers (families) of adults with anorexia nervosa (AN), which is different from working with families of younger adolescents. The main difference is in the area of rights and responsibilities of both parties. Moreover, as AN in adults is often a chronic condition, the treatment goal may not focus on recovery, but instead on improvement in quality of life. Thus the spectrum of nature and degree of parental involvement in the treatment of adults with AN is much broader than in children and adolescents. Our framework for intervention is based on a clear model of carer distress, from which targets for intervention follow. The paper outlines some of the core components of this work.     

Using Relaxation Techniques with Individuals and with Groups

The use of biofeedback, meditation, deep breathing relaxation, and imagery relaxation with individuals and with groups is described. The physical and mental well-being of people depends on learning ways to relax. Relaxation techniques reduce high levels of stress by facilitating the mind to switch from dwelling on day-to-day concerns to instead dwcll on relaxing themes. The body always responds to thinking processes; when the mind switches from dwellir~g on distressing thoughts to relaxing thoughts, the body becomes more relaxed.     

The Therapeutic Process with Children with Learning Disorders

Abstract

Clinicians who work with children and adolescents with learning disorders must be aware of the relationship between the learning disorder and the psychopathology the children present. This article offers a conceptual framework, based on psychoanalytic self psychology, to understand the modifications that are necessary in the treatment of this population. The author suggests that, in contrast to other approaches, it is not possible to conceptualize the treatment of these children as having a beginning, a middle, and an end. Rather, the therapeutic process is open-ended and conceived as occurring during a series of moments. The moments may be categorized as concordant, complementary, or disjunctive. During concordant moments a holding environment is created; during complementary moments the transference and countertransference is addressed; and during disjunctive moments the ruptures that inevitably occur during treatment are dealt with.     

Group intervention with children of parents with aids

This paper describes a format for group intervention with children of parents with AIDS. Therapeutic factors specific to group work with these children and special issues regarding AIDS are discussed. The stages of development of such groups are outlined, with particular attention paid to themes of grief and loss. Suggestions for future work in this area are given.
