研究者评估正常血压人群中动态血压与家庭高血压风险之间的关系,并研究增加动态血压是否可以改进先前Ohasama研究中建立的家庭高血压风险10年预测模型。方法:在该前瞻性研究中,研究者对没有家庭和动态高血压的日本大阪一般人群的410名参与者(女性占83.2%,年龄53.6岁)进行随访。采用Cox模型评估家庭高血压[家庭血压≥135/85 mmHg(1 mmHg=0.133 k Pa)或开始降压治疗]和模型改进的风险比(HR)。结果:在平均14.2年的随访期内,发生225例家庭高血压事件。

＜正＞Re-Os and Lu-Hf analyses of samples from the 4-km-thick section of -120 Ma southern Ontong Java Plateau （OJP） crust in Central Malaita, Solomon Islands, show that the Singgalo and underlying Kwaimbaita Fm. lavas, characterized by distinct Pb-Nd-Sr isotopic compositions （Tejada et al., 2002） also exhibit contrasting Os and Hf isotopic values. For samples with （?） 10 ppt Os, Singgalo Fm. lavas have markedly higher age-corrected I87Os/I88Os （0.1808 - 0.6030） than the Kwaimbaita Fm. lavas (0.1216 - 0.1654, except for one

在1995年兵库县南部地震期间,日本尼崎、高砂和南光3处钻孔场地的地表台站分别观测到了507cm/s2以上、187cm/s2和126cm/s2的水平峰值地面加速度(PGA)的强运动。利用对强弱地震动的互相关和频谱比的分析,我们给出了除南光之外在尼崎、高砂两处强地震动期间土壤非线性响应的定性证据。我们通过对剪切波速和与频率相关的阻尼因子的反演来评估土壤的非线性。反演得到砾石土的剪切模量比的应变依赖性比粘性土的要大,这与实验室试验结果一致。剪应变在10-4～10-3之间时,反演得到的尼崎、高砂两处砾石土和粘性土的剪切模量比的应变依赖性,分别同砾石土和粘性土实验室试验结果的经验关系相一致。这些结果支持了在砾石土和粘性土场地利用实验室试验所得剪切模量比来模拟强地震动。在尼崎,由主震反演得到的砾石土的阻尼因子在3个场地之中是最大的,但是阻尼因子的应变依赖性不如剪切模量比的应变依赖性那样显著。阻尼因子的应变依赖性不太显著的原因可能是由于散射衰减在低应变范围处于相对优势地位所致。

单位:日本东京市新宿区。目的:通过对新宿区的结核分枝杆菌的传染状况的评估,以便有效合理地分配卫生资源,从而成功地实施结核控制规划。设计:将结核分枝杆菌的基因型资料和结核患者资料结合起来的观察描述性研究。结果:男性、年龄小于40岁的患者和无家可归者的基因型成簇率显著较高,他们的调整比值比和95%可信区间分别是(aOR 1.94,95%CI 1.04—3.65,P=0.038),(aOR 2.09,95%CI 1.17—3.71,P=0.012),(aOR 2.72,95%CI 1.42—5.20,P=0.002),而国外出生患者的基因型成簇率却较低(aOR 0.21,95%CI 0.06—0.76,P= 0.017)。在152例结核患者的45个基因型簇中, 102(67.1%)例患者的26个簇是由无家可归者和非无家可归混合而成,其中一个混合簇包括1个在日本出生的8个月的婴儿。结论:此研究显示结核分枝杆菌在无家可归人群的传播要比在非无家可归人群中更常发生。然而,偶然的接触也会引起结核分枝杆菌在无家可归者和普通人群之间的传播。

Background: Experimental manipulations of tree diversity have often found overyielding in mixed-species plantations. While most experiments are still in the early stages of stand development, the impacts of tree diversity are expected to accumulate over time. Here, I present findings from a 31-year-old tree diversity experiment(as of2018) in ***: I find that the net diversity effect on stand biomass increased linearly through time. The species mixture achieved 64% greater biomass than the average monoculture biomass 31 years after planting. The complementarity effect was positive and increased exponentially with time. The selection effect was negative and decreased exponentially with time. In the early stages(≤ 3 years), the positive complementarity effect was explained by enhanced growths of early-and mid-successional species in the mixture. Later on(≥ 15 years), it was explained by their increased survival rates owing to vertical spatial partitioning — i.e. alleviation of self-thinning via canopy stratification. The negative selection effect resulted from suppressed growths of late-successional species in the bottom ***: The experiment provides pioneering evidence that the positive impacts of diversity-driven spatial partitioning on forest biomass can accumulate over multiple decades. The results indicate that forest biomass production and carbon sequestration can be enhanced by multispecies afforestation strategies.

视神经束综合征中视网膜神经纤维层的厚度

世界核心医学期刊文摘(眼科学分册) 2006年第1期 57-57页

Background: Optic tract syndrome (OTS) is characterized by incongruous homonymous hemianopia and a perpendicular pattern of bilateral optic atrophy due to the optic tract lesion. However, loss of retinal nerve fiber layer thickness (RNFLT)-associated with OTS has not been quantitatively assessed. Case: A 20-year-old woman with blunt head trauma showed normal visual acuity, color vision, ocular motility, and intraocular pressure. Because of a relative afferent pupillary defect in her left eye and left-sided homonymous hemianopia, we suspected right-sided optic tract damage, although magnetic resonance imaging detected no intracranial lesion. Observations: Using optical coherence tomography (OCT), the RNFLT of this case was measured at 31 months after the trauma and compared with age-matched normal controls (n=41). Nasal, temporal, superior, and inferior quadrant RNFLT was reduced by 22% , 21% , 5% , and 46% in the right eye and 76% , 64% , 25% , and 27% in the left eye, respectively. The reduction was >3× the standard deviation of the normal mean values in the nasal and temporal quadrants of the left eye and in the inferior quadrant of the right eye. Conclusions: OCT can determine the RNFLT reduction corresponding to the characteristic patterns of optic atrophy of OTS.
