甘精胰岛素注射时段对2型糖尿病患者空腹血糖的影响

比较甘精胰岛素在不同时段注射对2型糖尿痛患者空腹血糖的影响.最终选择89例2型糖尿病患者随机分为两组接受甘精胰岛素早餐前(A组,n=46)和夜间睡前(B组,n=43)注射治疗,观察两组患者空腹血糖的变化.结果显示,所有患者使用甘精胰岛素治疗以后,空腹血糖水平较治疗前均有明显下降,具有统计学差异(P均<0.001).但B组的空腹血糖水平下降幅度更为明显,两者相比具有统计学差异(P<0.001).故在相同剂量的情况下,夜间睡前注射甘精胰岛素较晨间注射具有更强的降糖幅度,效果更好.     

胸腔闭式引流术后感染相关因素的探讨与对策

胸腔闭式引流术是一项有创性操作,多种因素可能会引起胸膜腔及肺内感染。为了预防及处理胸腔闭式引流术后的相关性感染,我们从临床角度讨论更换胸腔闭式引流瓶的间隔时间、胸腔闭式引流管口的消毒、胸腔引流液逆流的预防、胸腔引流管的更换以及由于留置胸腔闭式引流引起的肺内感染的处理等问题,为临床医护人员对该项操作提供参考和对策。

类比推理的发展理论评析

类比在认知科学领域具有特殊的地位,儿童类比推理能力的发展是其认知发展的重要成分之一。本文系统介绍了类比推理发展研究中的几个重要理论,即能力限制说、知识经验说和关系转换说等。在此基础上,作者进一步对类比推理发展研究中涉及的几个焦点问题,如类比推理出现的最早年龄,类比推理发展的影响因素及类比推理的发展趋势等进行了综合评析。     

Effects of gender similarity on relationships between person–group value fit and work attitudes

The present study assessed the effect of gender similarity as a potential moderator of the relationships between person–group (P–G) value fit and work attitudes. Specifically, we predicted that the effect of P–G value fit (in terms of social integration values) on individual attitudes would be stronger for individuals who had a similar gender than those of a different gender. Based on data obtained from 197 employees in South Korea, we found that when the focal individual had high gender similarity with his or her group, the relationships between P–G value fit and job satisfaction and between P–G value fit and turnover intentions were more prominent. Furthermore, these moderating effects were significant for men, but not for women.     

Culture-specific patterns in the prediction of life satisfaction: roles of emotion, relationship quality, and self-esteem

This study was conducted to explore the culture-specific roles of emotion, relationship quality, and self-esteem in determining life satisfaction. It was hypothesized that maintaining good interpersonal relationships would make individuals in collectivistic cultures not only feel good about their lives but also feel better about themselves. Furthermore, two emotion variables--emotional expression and emotion differentiation--were proposed as possible determinants of relationship quality. It was hypothesized that emotional expressiveness would be more important for maintaining good interpersonal relationships in individualistic societies but emotion differentiation would be more important in collectivistic cultures. These hypotheses were tested with Euro-American, Asian American, Korean, and Chinese groups using multigroup analyses in a structural equation model. Results supported all proposed hypotheses and indicated that emotion differentiation contributes to maintaining good interpersonal relationships in collectivistic cultures, which contributes to self-esteem and satisfaction with life.     

The Specific Role of cGMP in Hippocampal LTP

Previous results have suggested that cGMP is involved in hippocampal long-term potentiation (LTP), perhaps as the presynaptic effector of a retrograde messenger. However, other studies have failed to replicate some of those results, making the role of cGMP uncertain. We therefore reexamined this question and identified several variables that can affect the contribution of cGMP. First, brief perfusion with 8-Br–cGMP before weak tetanic stimulation produced long-lasting potentiation in the CA1 region of hippocampal slices, but more prolonged perfusion with 8-Br–cGMP before the tetanus did not produce long-lasting potentiation. Second, the activity-dependent long-lasting potentiation by cGMP analogs was reduced when NMDA receptors were completely blocked, indicating that NMDA receptor activation contributes to, but is not required for, the potentiation. The amount of reduction of the potentiation differed with different protocols, and in some cases could be complete. Third, LTP produced by strong tetanic stimulation in the stratum radiatum of CA1 (which expresses eNOS) was blocked by inhibitors of soluble guanylyl cyclase or cGMP-dependent protein kinase, but LTP in the stratum oriens (which does not express eNOS) was not. The results of these experiments should help to explain some of the discrepant findings from previous studies, and, in addition, may provide insights into the mechanisms and functional role of the cGMP-dependent component of LTP.     

Remembering: A tribute to Liston Mills

Thank you, Liston, for who you are and for what you have given so many for so long.     

Family therapy and communion

There has been a shift of healing authority in our culture from priestly practitioners to scientific and medical practitioners. As part of this change the care and healing of stressed or broken families is now seen as the responsibility of the family therapist. A consequence of this has been some role confusion on the part of the clergy and therapists. A comparison of the symbolic complex of belief and value systems used in MacGregor's team-family method of family therapy and Joseph Haroutunian's theology of the church shows four striking similarities. The implications of these similarities for the continued confusion or clarity of the roles of priest and therapist are noted.Rev.
