老年糖代谢异常患者血浆NT—proBNP与血管内皮功能早期监测意义

通过检测老年糖代谢异常患者的血浆N末端血清脑钠肽前体（NT—proBNP）水平与肱动脉血管内皮依赖性舒张功能（FMD）,探讨其早期监测意义。共77例观察对象,其中12例血糖正常的健康老人为对照组,65例老年糖代谢异常组患者根据空腹血糖（FBG）和糖耐量2小时（0GTT2h）血糖水平分为空腹血糖受损组（IFG）14例、糖耐量受损组（IGT）23例和2型糖尿病组（DM）28例。各组均检测血浆NT—proBNP水平和无创超声监测FMD。随着血糖代谢异常程度加重,比较正常组,糖代谢异常组的血浆NT—proBNP水平升高（P〈0．01）,FMD调节下降（P〈0．01）;糖代谢异常发展过程中,IFG阶段FMD即出现舒张失调（P〈0．05）;IGT阶段血浆NT-proBNP水平升高有意义并达到无症状心衰诊断标准（P〈0．01）,且FMD出现舒张过度调节,提示收缩和舒张功能双向调节不良。空腹血糖升高增加血管内皮依赖性舒张功能损害,当FBG合并（或）餐后血糖升高,血浆NT—proBNP水平升高可以成为早期预测慢性无症状心功能不全的危险因素。因此,关注老年糖代谢异常早期阶段进程,并联合血浆NT—proBNP水平和血管内皮依赖性舒张功能监测,不仅对靶器官保护具有早期预警意义,而且是临床控制血糖管理的重要而简易的方法之一。     

Comparison of the role of self-efficacy and illness representations in relation to dietary self-care and diabetes distress in adolescents with type 1 diabetes

This cross-sectional study examined the joint effects of self-efficacy and illness representations on dietary self-care and diabetes distress in adolescents with type 1 diabetes by comparing two theoretical models: the Self-regulation Model (Leventhal, H., Meyer, D., & Nerenz, D. (1980). The common-sense representations of illness danger. In S. Rachman (Ed.), Medical Psychology (Vol. 2, pp. 7–30). New York: Pergamon.) and Social Cognitive Theory (Bandura, A. (1997). Self efficacy: The exercise of control. New York: W.H. Freeman.). One hundred and fifty-one adolescents with type 1 diabetes completed self-report measures of dietary self-efficacy, illness representations, dietary self-care and diabetes distress. Data were analysed using structural equation modelling. The model best supported by the data (Leventhal's Self-regulation Model) showed that dietary self-efficacy, perceived consequences and treatment effectiveness had direct and independent effects on both dietary self-care and diabetes distress. Together with dietary self-efficacy, perceived short-term treatment effectiveness was a significant predictor of dietary self-care. Age was found to be a negative predictor of short-term treatment effectiveness beliefs. Diabetes distress was best predicted by self-efficacy and perceived consequences. It can be concluded that to target effectively dietary self-care and distress, clinicians should focus on key illness representation variables (perceived short-term treatment effectiveness and perceived consequences) in conjunction with self-efficacy.

2型糖尿病大血管病变机理和糖尿病治疗

2型糖尿病大血管病变与代谢综合征密切相关.现代医学认为两者的根本原因是胰岛素抵抗,导致糖耐量下降,血脂紊乱,高胰岛素血症,高血压和高凝状态等.从系统论的观点阐述了代谢综合征的相互关系和2型糖尿病大血管病变发病机理,并进一步从该观点阐明2型糖尿病的防治策略.     

胰岛素研究的新突破

人类与糖尿病抗争的历史最早可上溯到公元前1500年前,但直到20世纪20年代胰岛素才由生理学家FredrickBanting等发现。自此,挽救了数以百万计的糖尿病患者的生命。随后,人们在研究胰岛素如何调节物质代谢时,意外发现含胰岛素的激化液(Glucose-insulin-potassium,GIK)可改善急性心脏梗死患者的症状。提示,胰岛素还具有其它多方面的生理功能。近期研究证明,胰岛素确有抗心肌坏死与凋亡、进而保护缺血再灌注心肌的作用,这再次引起了人们对胰岛素进行深入研究的兴趣。从胰岛素的发现到对其新的作用机制的认识给我们带来许多有益的启示。     

糖尿病足诊疗与预防进展

糖尿病足是糖尿病的严重并发症,血管狭窄闭塞、神经病变和感染是主要的临床表现,本文主要从糖尿病足的定义、病因、病理生理、临床表现、检测方法、分级及治疗和预防进展方面进行总结。糖尿病足的诊治是个系统工程,单一的方法难以治愈,且治疗效果欠佳,故我们在临床上以预防为主,早期诊断,早期治疗。     

Coping with type 1 diabetes through emerging adulthood: Longitudinal associations with perceived control and haemoglobin A1c

Objective: This study, which is part of a larger longitudinal study focusing on the biopsychosocial functioning of emerging adults with type 1 diabetes, examined how perceived personal control, coping and HbA_1c relate to one another over time.

Design and main outcome measures: Emerging adults with type 1 diabetes (18–30 years old) participated in a two-wave longitudinal study spanning five years (N = 164 at Time 1). At both times, patients completed questionnaires on perceived control and coping (i.e. diabetes integration, avoidant coping and passive resignation). HbA_1c values were obtained from treating clinicians. We investigated the directionality of effects using cross-lagged path analysis.

Results: Higher HbA_1c values predicted relative decreases in diabetes integration and increases in avoidant coping five years later. Feeling less in control over diabetes predicted the use of passive coping over time. Passive coping predicted a relative decrease in perceived control five years later.

Conclusion: These findings indicate that tackling poor glycaemic control is not only important to avoid medical complications but also to prevent patients from resorting to more avoidant coping strategies. Furthermore, given the longitudinal interplay between perceived control and passive coping, it is important that intervention efforts include both cognitive and behavioural components to be effective.
