| 1 | The leaf size/number trade-off in herbaceous angiosperms显示文摘Aims In this study,we examined the extent to which between-species leaf size variation relates to variation in the intensity of leaf production in herbaceous angiosperms.Leaf size variation has been most commonly interpreted in terms of biomechanical constraints(e.g.affected by plant size limitations)or in terms of direct adaptation associated with leaf size effects in optimizing important physiological functions of individual leaves along environmental gradients(e.g.involving temperature and moisture).An additional interpretation is explored here,where adaptation may be more directly associated with the number of leaves produced and where relatively small leaf size then results as a trade-off of high‘leafing intensity’—i.e.number of leaves produced per unit plant body size.Methods The relationships between mean individual leaf mass,number of leaves and plant body size were examined for 127 species of herbaceous angiosperms collected from natural populations in southern Ontario,Canada.Important Findings In all,88%of the variation in mean individual leaf mass across species,spanning four orders of magnitude,is accounted for by a negative isometric(proportional)trade-off relationship with leafing intensity.These results parallel those reported in recent studies of woody species.Because each leaf is normally associated with an axillary bud or meristem,having a high leafing intensity is equivalent to having a greater number of meristems per unit body size—i.e.a larger‘bud bank’.According to the‘leafing intensity premium’hypothesis,because an axillary meristem represents the potential to produce either a new shoot or a reproductive structure,high leafing intensity should confer greater architectural and/or reproductive plasticity(with relatively small leaf size required as a trade-off).This greater plasticity,we suggest,should be especially important for smaller species since they are likely to suffer greater suppression of growth and reproduction from competition within multi-species vegetation.Accordingly,we tested and found support for the prediction that smaller species have not just smaller leaves generally but also higher leafing intensities,thus conferring larger bud banks,i.e.more meristems per unit plant body size. | Thea Whitman Lonnie W.Aarssen | 2010 | Journal of Plant Ecology2010，3，1： | 24 |

| 3 | 不同浓度罗哌卡因硬膜外镇痛在上腹部大手术中的应用:一项前瞻、随机、双盲、安慰剂对照研究显示文摘背景已有大量文献报道了不同临床条件下实施的胸段硬膜外镇痛(TEA)所具有的各种优势。然而在复合吸入麻醉药、液体治疗、使用血管加压药及血流动力学变化的情况下,手术中硬膜外镇痛应用不同浓度局部麻醉药的影响却罕有报道。我们的实验报道了TEA联合全麻在行上腹部大手术患者中的应用情况。方法45例行上腹部大手术的患者随机分为三组。组1与组2TEA每60分钟分别给予0.5%和0.2%的罗哌卡因10ml和0.5μg舒芬太尼,组3每60分钟硬膜外给予10ml生理盐水。切皮前麻醉维持吸入1个最低肺泡有效浓度(MAC)的地氟烷复合60%的N2O。手术中连续监测脑电双频谱指数(BIS)和临床体征(PRST评分),根据BIS值调节吸入地氟烷的浓度,使其维持在50~55。手术中镇痛不足定义为脉搏加快、出汗、流泪的PRST评分〉2分或者平均动脉压(MAP)升高大于基础值的20%,其治疗可调节呼气末地氟烷浓度至1MAC,若己超过1MAC可静脉输注瑞芬太尼。低血压定义为MAP下降大于基础值的20%,其治疗可减少吸入地氧烷的浓度并维持BIS值在50。55,血压仍低时可根据中心静脉压输注晶体液和去甲肾上腺素。结果组1和组2的呼气未地氰烷浓度显著降低,分别至0.7±0.1MAC(P〈0.001)和O.8±0.1MAC(P〈0.001),而组3无显著降低。组l和组2的全部患者在20分钟内部发生了显著的低血压(组1MAP从80±10mmHg到56±5rainHg),(组2MAP从78±18mmHg到58±7mmHg),P〈0.01。而组3MAP无明显变化(74±12mmHg到83±15mmHg,P=0.42)。三组心率都未发生显著变化。并且三组间静脉输液量和去甲肾上腺素的需要量无显著差异。组3(7.2±4.9mg·kg-1·h-1)与组2(1.6±2.2mg·kg-1·h-1)相比,手术中使用了更大剂量的瑞芬太尼,P〈0.01。硬膜外应用0.5%罗哌卡因的患者任何时间都不需要输注瑞芬太尼。结论硬膜外应用0.5%的罗哌卡因与0.2%的浓度相比,在使用了一定剂量的血管加压药和液体治疗的情况下,保证一定麻醉深度的同时可更显著地降低地氟烷浓度。 | Perildis Panousis Axel R.

| 16 | 压力支持通气和双相气道正压通气通过肺血流重新分布从而提高氧合显示文摘背景机械通气时保留自主呼吸(spontaneousbreathing,SB)可改善气体交换,主要是因为这种通气方式可使萎陷的肺复张。在保留SB的机械通气中,常选择压力支持通气(pressuresupportventilation,PSV)和双相气道正压通气(biphasicpositiveairwaypressure,BIPAP)。但医师对这些辅助性机械通气方式改善肺功能的机制却不甚了解。我们评价了采用PSV和BIPAP改善氧合的机制。方法5头猪(25-29.3kg)于仰卧位行机械通气,并通过清除肺表面活性物质诱发其发生急性肺损伤(acutelung砸jury,Au)。状态稳定后,给予BIPAP通气,初期较低持续气道正压设置为5cmH2O,随后逐渐增加持续气道正压至维持潮气量在6-8ml/kg。减浅麻醉深度,当SB≥每分通气量的20%时,随机进行1小时的PSV或BIPAP+SB通气。于呼气末行全胸螺旋式计算机体层扫描,并记录肺功能参数。静脉给予荧光微球体来记录肺血流(pulmonarybloodflow,PBF),并利用空间聚类分析来评估每种通气方式对PBF重新分布的影响。结果Au损伤肺功能并加大了下肺萎陷或不张组织的面积(P〈0.05)。和对照组比较,PSV和BIPAP+SB的通气模式提高了氧合并减少了静脉血掺杂(P〈0.05)。尽管如此,我们观察到自主呼吸时下肺的不张肺组织或通气不良组织明显增加,而可正常通气的肺组织减少。观察到6例中有5例行PSV或sB+BIPAP通气时PBF由下至上重新分布,肺通气也较好。结论在ALI模型中采用PSV或BIPAP+SB行机械通气可改善氧合,减少静脉血掺杂的原因为PBF由下至上的重新分布,而不是因为下肺复张。 | Alysson R.
