Investigation of the Type A Behavior Pattern (TABP) of pre-school children was conducted to determine the influence of the mother-child relationship on the development of TABP. The incidence of TABP was 44.2% (51.7% in boys and 38.7% in girls). The TABP tendency of the boys decreased as the manifest dissension or conflict in the family grew, in marked contrast with the tendency seen in girls, suggesting that conflict in the family can either weaken or reinforce TABP. 相似文献

Acrolein is a highly reactive alpha,beta-unsaturated aldehyde produced endogenously during lipid peroxidation and naturally distributed pervasively in living environments, posing serious threats to human health if not properly metabolized. In this study, we report aldose reductase-like-1 (ARL-1) as a novel enzyme that catalyzes the reduction of acrolein and protects cells from their toxicity. Using purified ARL-1 protein, we determined its enzymatic activity in response to acrolein and defined its steady-state kinetics with K(m) and V(max) at 0.110 +/- 0.012 mM and 3122.0 +/- 64.7 nmol/mg protein/min, respectively. By introducing a functional Enhanced Green Fluorescent Protein (EGFP)/ARL-1 fusion protein into 293T cells, we demonstrated that plating efficiency in liquid culture and focus formation in soft agar increased by more than 60% (p < 0.05), compared to the vector control cells. More significantly, at a low dose of 5 microM acrolein, EGFP/ARL-1 expression enhanced both plating efficiency and focus formation by more than threefold, and the foci (in soft agar) of 293T cells expressing EGFP/ARL-1 were significantly larger than those of the vector control cells. At high concentrations of acrolein (25 and 50 microM), EGFP/ARL-1 protein prevented oncotic death of 293T cells induced by acrolein. In summary, our data demonstrated for the first time that the ARL-1 protein protects 293T cells from acrolein toxicity. Due to the high toxicity and wide distribution of acrolein, this finding is important to the understanding of its detoxification mechanisms. 相似文献

A case-control study of breast cancer among Japanese women: with special reference to family history and reproductive and dietary factors 总被引:8,自引:0,他引:8

Summary To study the effects of family history and reproductive, anthropometric, and dietary factors on the risk of breast cancer among low risk populations, we conducted a hospital-based case-control study involving 908 patients with breast cancer and their matched controls, in Japan. A positive family history of breast cancer significantly increased the risk of breast cancer (odds ratio = 1.52, 95% confidence interval: 1.14–2.03). The risk further increased with increasing number of family members affected. Obesity, single marital status, fewer births, a late childbirth, and less consumption of green-yellow vegetables and dairy products were also associated with an increased risk of breast cancer. These associations were independent in multivariate analyses. There was no increase in risk associated with consumption of high fat foods. When analyzed by menopausal status, the association with family history of breast cancer, especially in the first degree of relatives, was more evident for premenopausal breast cancer. The associations with obesity and lower consumption of dairy products were more pronounced for postmenopausal breast cancer, while those with lower parity and single marital status were stronger for premenopausal breast cancer. 相似文献

胃癌高系家族成员胃蛋白酶原C基因多态性及其诊断意义的探讨 总被引:1,自引:0,他引:1
采用限制性酶切片段长度多态性分析法,检测在胃癌高发区庄河检出的19例胃癌高系家族成员胃蛋白酶原C基因多态性,发现三种常见片段及一种稀有片段。对其中4例携带稀有片段的受检者进行了胃镜追踪观察,2.5年后发现1例早期胃癌。本文对此作了初步探讨。 相似文献

研究目的调查分析出院后精神分裂症患者的心理状况,了解存在的问题并探讨解决的对策。研究方法对77例出院后精神分裂症病人就22项心理问题进行调查统计,并对比男女患者差异。结果男性易发脾气、借酒消愁、因病影响工作安排的现象较女性突出,而女性的婚姻状况较紧性明显。结论社区防治的病人心理问题较繁杂,因此防治工作应重视患者的心理特点,解决患者的实际问题。 相似文献

Based on data from a sample of 4500+ people aged 65+ living in the community (ie not in residential care) in Liverpool, this article presents data on the availability of kin and levels of contact with family, friends neighbours and community groups, and compares the distribution of support network types of those identified as cases of dementia with non-cases. It is shown that dementia sufferers are more likely to live with others and to have more contact with family members and less contact with friends, neighbours and community groups than non-sufferers. It is also shown that the distribution of network type is distinctively different for cases and non-cases and it is suggested that this reflects the greater ability of some types of network to support continued community residence in the face of the onset of dementia. 相似文献

小学生应对同伴冲突自我监控训练的实验研究 总被引:1,自引:0,他引:1
目的探索提高小学生同伴冲突应对能力的方法。方法采用2×2因素实验设计,运用自我监控的问题解决模式对106名三、五年级小学生(实验组)进行同伴冲突应对能力的训练,另101名三、五年级小学生为对照组,采用儿童社交问题解决访谈提纲和小学生社交技能教师评定量表于实验前后对两组学生施测。结果经过自我监控训练后,在解决冲突的有效性上,三年级实验组有显著提高(9.58±1.60/8.12±2.36,t=3.846,P<0.01),在解决冲突的适应性上,三、五年级实验组均有显著提高(10.52±1.87/7.96±2.44,t=6.612,P<0.01;11.02±1.65/7.54±2.44,t=9.561,P<0.01);教师评定的结果表明,训练后三、五年级实验组处理冲突的能力均有显著提高(29.35±1.70/26.62±4.66,t=4.063,P<0.01;31.59±2.73/27.59±4.39,t=6.147,P<0.01)。结论自我监控训练是一种有效提高小学生同伴冲突应对能力的方法。 相似文献
