对于女性盆腔脏器脱垂的手术治疗,传统的手术方式包括阴道封闭术、曼氏手术和阴式全子宫切除术.阴道封闭术操作相对简单,适用于无性生活要求的、合并症较多的年老体弱者,但术后可能存在新发压力性尿失禁,并且导致性功能障碍,术中是否切除子宫尚有争议.曼氏手术保留子宫、操作简单,但术后脱垂复发及妊娠后宫颈机能不全问题仍有待研究.阴式全子宫切除术对于POP-Q评分II期及以内的脱垂患者,治疗效果最佳,期别高的患者术后复发仍可使用保守或再次手术治疗补救,本手术方式术后较少出现性交痛.总而言之,选择适当的适应证并积极与患者沟通后,女性盆腔脏器脱垂的传统手术治疗仍为不错的治疗方式. 相似文献

在不同领域的道德判断中,情绪可能起着“催化剂”的作用。一种特定情绪对应一种核心评价;一种情绪只影响某一道德领域的判断,不同情绪的影响是特异性的;进化心理学和具身认知对道德判断中存在的评价倾向和特异性效应进行了解释。未来研究需要探索评价倾向与特异性效应的内在心理机制。以及进一步探讨文化等第三变量对不同情绪与特定领域道德判断的影响。 相似文献

谊研宛采用工作压力源量表、压力反应量表以及积极心理资本问卷对天津市某企业230名员工进行了调查。分析了心理资本与工作压力源和压力反应的关系及其作用机制。结果发现:(1)工作压力源对压力反应有显著的正向预洲作用;(2)心理资本对压力反应有显著的负向预测作用;(3)心理资本在工作压力源与压力反应之间起部分中介作用而不是调节作用,其中中介效应占总效应的比例为16%;(4)心理资本在各种工作压力源与压力反应问均起到中介作用,中介效应和直接效应的比值介于17.4%-26.1%之间。 相似文献

Although many forms of differential treatment based on group membership are perceived to be legitimate, disadvantaged group members’ responses to discrimination have been studied primarily in contexts in which such treatment is appraised as illegitimate. This has resulted in an impoverished understanding of differential group-based treatment and a failure to illuminate the processes by which discrimination can shift from being seen as legitimate to being viewed as illegitimate. We discuss the determinants of disadvantaged group members’ legitimacy appraisals and the de-legitimisation process, whereby forms of discrimination appraised as legitimate come to be increasingly perceived as illegitimate. Whether group-based exclusion is addressed collectively or individually depends on socio-structural factors such as the pervasiveness of discrimination, impermeability of intergroup boundaries, and the availability of cognitive alternatives to the status quo. We conclude that understanding the antecedents and consequences of legitimacy appraisals is necessary to develop a comprehensive account of disadvantaged group members’ experiences of group-based discrimination. 相似文献

Exposure to a microgravity environment leads to adverse effects in motion and musculoskeletal properties. However, few studies have investigated the recovery of altered locomotion and muscle atrophy simultaneously. The authors investigated altered locomotion in rats submitted to simulated microgravity by hindlimb unloading for 2 weeks. Motion deficits were characterized by hyperextension of the knees and ankle joints and forward-shifted limb motion. Furthermore, these locomotor deficits did not revert to their original form after a 2-week recovery period, although muscle atrophy in the hindlimbs had recovered, implying discordance in recovery between altered locomotion and muscle atrophy, and that other factors such as neural drives might control behavioral adaptations to microgravity. 相似文献

The purpose of this study was to investigate the differences of knee concentric and eccentric strength and impact related knee biomechanics between jumpers and non-jumpers during step-off landing tasks. Ten male college swimming athletes (non-jumpers) and 10 track and volleyball athletes (jumpers) were recruited to participate in two test sessions: a muscle strength testing session of concentric and eccentric extension for dominant knee joint at 60 °/s and 180 °/s and a landing testing session. The participants performed five trials of step-off landing in each of four conditions: soft and stiff landing from 0.4 m and 0.6 m landing heights. The three-dimensional kinematics and ground reaction force were recorded simultaneously during step-off landing conditions. The results showed that the jumpers had significantly greater peak knee eccentric extension and concentric flexion torques compared to the non-jumpers. No significant group effects were found for peak vertical ground reaction force and knee range of motion during landing. The jumpers had significantly greater knee contact flexion angle, maximum knee flexion angle and initial knee extension moment compared to the non-jumpers. These results suggest that these athletes adopted a favorable impact attenuation strategy that is related to the greater knee eccentric muscle strength and training. 相似文献
