可溶性CD40L、MMP-9与颈动脉粥样硬化及急性脑梗死的关系

目的探讨可溶性CD40L(sCD40L)、基质金属蛋白酶-9(MMP-9)与颈动脉粥样硬化及急性脑梗死(ACI)的关系。方法选取首次发病的ACI患者90例和健康对照组30例,采用双抗体夹心酶联免疫吸附试验(ELISA)测定血清sCD40L、MMP-9的水平。应用颈动脉超声检测颈动脉内膜状况。比较不同程度颈动脉粥样硬化及不同面积脑梗死患者血清sCD40L、MMP-9的水平变化,并对所有脑梗死患者进行神经功能缺损评分。结果 ACI患者血清sCD40L、MMP-9的水平显著高于对照组(P0.01);大梗死组血清sCD40L、MMP-9水平高于中、小梗死组,中梗死组高于小梗死组,差异均有统计学意义(均P0.01);随着颈动脉粥样硬化程度加重,脑梗死病情越重及脑梗死面积越大,血清sCD40L、MMP-9的水平也越高;血清sCD40L与MMP-9的水平呈正相关(r=0.887,P0.01)。结论 ACI患者血清sCD40L、MMP-9水平可以反映颈动脉粥样硬化斑块的性质和稳定性、脑梗死面积与病情的严重程度;CD40-CD40L系统可能通过上调MMP-9导致颈动脉粥样硬化斑块不稳定。     

脑梗死患者血清可溶性CD40L、白介素-18水平的变化及意义

强化胰岛素治疗在重型颅脑创伤救治中作用的荟萃分析

目的 评价强化胰岛素治疗(IIT)与常规胰岛素治疗(CIT)在重型创伤性脑损伤(sTBI)救治中的作用.方法 系统性检索中、外文文献数据库中的临床随机对照试验(RCT),使用Review Manager软件进行荟萃分析.评价指标包括:早期(住院期间)病死率、远期(3个月后)病死率、感染率、远期神经功能损伤量表(NSS)评分、低血糖事件发生率等.结果 共有12篇文献、共计1 277名患者纳入本项分析.早期病死率的合并OR =0.78 (95％ CI:0.53 ～ 1.15,P=0.21);晚期病死率的合并OR =0.85 (95％ CI:0.63 ～ 1.15,P=0.30);感染率的合并0R=0.49 (95％ CI:0.37～0.64,P＜0.00001);远期良好NSS比例的合并OR=1.62 (95％ CI:1.18 ～2.21,P=0.003);低血糖事件发生率的合并OR =4.33 (95％ CI:1.39 ～ 13.49,P=O.01)和2.61(95％ CI:2.27 ～2.99,P＜0.00001).结论 在sTBI救治中,与CIT相比,IIT对降低病死率无明显作用,但可降低患者感染率、改善远期神经功能,同时低血糖事件却明显增多.故IIT不太适合继续应用于救治重型颅脑创伤,进一步的证据还有待深入研究.     

Physical and Sexual Abuse and Neglect and Eating Disorder Symptoms

For eating-disordered patients with a history of post-traumatic stress, childhood abuse and neglect, and dissociative disorder, eating behavior symptoms may function as a rational response to unmetabolized traumatic experiences. This paper will review trauma-based theory, dissociation, abreactive, and ego-states therapy as they apply to eating disorder patients.     

Efficacy and Effectiveness of Child and Adolescent Psychotherapy and Pharmacotherapy

Decades of intervention research have produced a rich body of evidence on the effects of psychotherapies and pharmacotherapies with children and adolescents. Here we summarize and critique that evidence. We review findings bearing on the efficacy of psychosocial treatments and medications under controlled experimental conditions. We also report evidence, where available, on the effectiveness of both classes of treatment with clinically referred youth treated in real-world clinical contexts. In general, the large body of evidence on efficacy contrasts sharply with the small base of evidence on effectiveness. Addressing this gap through an enriched research agenda could contribute importantly to linking scientific inquiry and clinical practice—to the benefit of both ventures. This is one element of a multifaceted agenda for future research and for synthesis of research, which will require the interplay of multiple disciplines related to child and adolescent mental health.     

Presence and severity of anorexia and bulimia among male and female Omani and non-Omani adolescents

OBJECTIVE: The population of Oman is a heterogeneous mix of nationalities providing a natural setting for studying the cross-cultural differences in the presence and severity of eating disorders as well as an opportunity for evaluating the performance of measurement instruments for these disorders. METHOD: Disordered eating screening instruments (the Eating Attitude Test and the Bulimic Investigatory Test) were administered to Omani teenagers, non-Omani teenagers, and Omani adults. RESULTS: On the Eating Attitude Test, 33% of Omani teenagers (29.4% females and 36.4% males) and 9% of non-Omani teenagers (7.5% of males and 10.6% females) showed a propensity for anorexic-like behavior. On the Bulimic Investigatory Test, 12.3% of Omani teenagers showed a propensity for binge eating or bulimia (13.7% females and 10.9% males). Among the non-Omani teenagers, 18.4% showed a tendency toward bulimia, with females showing a slightly greater tendency than males. In contrast, barely 2% of Omani adults showed either a presence of or a severity of disorderly behavior with food. CONCLUSION: Omani teenagers scored significantly higher than other ethnic groups and Omani adults. This finding is discussed in the light of emerging evidence from many parts of the world suggesting that cultural transition, compounded by demographic constraints, plays a significant role in abnormal eating attitudes.     

Physical and Sexual Abuse and Neglect and Eating Disorder Symptoms

Abstract

For eating-disordered patients with a history of post-traumatic stress, childhood abuse and neglect, and dissociative disorder, eating behavior symptoms may function as a rational response to unmetabolized traumatic experiences. This paper will review trauma-based theory, dissociation, abreactive, and ego-states therapy as they apply to eating disorder patients.     

Micro-affirmations and Recovery for Persons with Mental Health and Alcohol and Drug Problems: User and Professional Experience-Based Practice and Knowledge

Recurrent factors contributing to a recovery process from co-occurring mental health and addiction problems mentioned by users and professionals have been analyzed as part of working alliances and helpful relationships. Still, we lack knowledge about how helpful relationships are developed in daily practice. In this article, we focus on the concrete construction of professional helpful relationships. Forty persons in recovery and fifteen professionals were interviewed. The interviews were analyzed according to thematic analysis, resulting in three themes presented as paradoxes (1) My own decision, but with the help of others; (2) The need for structures and going beyond them; and (3) Small trivial things of great importance. Micro-affirmations have a central role in creating helpful relationships by confirming the individuals involved as more than solely users or professionals. More attention and appreciation should be paid to practices involving micro-affirmations.

     

Opiate and digitalis receptor assays distinguish between neuroexcitant and inactive organochlorines and between anesthetics and convulsants

Specific binding of [3H]naloxone to rat brain tissue in vitro was inhibited by the excitant organochlorinated insecticides (OCI), by ether (E) and octanol (OCT), and by the convulsant indoklon (IND) and its anesthetic isomer, isoindoklon (ISO). In the presence of 100 mM NaCl the inhibition of naloxone binding by E, OCT and ISO was greatly potentiated, whereas that by OCI and IND was attenuated. KCl (100 mM) was equally effective as NaCl on the action of anesthetics, but the effect of the excitant drugs was, in contrast to NaCl, unaffected by KCl. Specific binding of [3H]ouabain in the absence of Na, was depressed by anesthetics and enhanced by neuroexcitants. In the presence of NaCl, which by itself inhibits ouabain binding to brain, both anesthetics and excitants enhanced ouabain binding. DDE, a non-insecticidal analog of DDT, and the dimethyl derivative of the OCI, lindane, were inactive in the receptor assays. These observations point to a unique isolated system which responds consistently to anesthetic agents as a class and, in a different way, to neuroexcitant compounds.
