An unusual isolate from watercress mottle,in association withturnip mosaic and cucumber mosaic viruses,produced small white local necrotic lesions on sapinoculated leaves of Nicotiana tabacum,N.rustica,N.glutinosa,Datura stramonium,Solanumnigra,Brassica pekinensis,B.chinensis,B.campestris,Raphanus sativa,Nasturtium officinale,Spinacia oleracea and Amaranthus mangostanus while small brown local necrotic lesions onGomphrena globosa,Phaseolus vulgaris,Dolichos lablab...

在北京香山樱桃沟野生的十字花科豆瓣菜上发现有芜菁花叶病毒、黄瓜花叶病毒以及一种未报导过的"小白斑"病毒的复合病。小白斑病毒在20多种寄主上，包括十字花科，单独汁液接种时只能产生局部坏死病斑，不能系统侵染；单独接种而能系统感染的寄主有百日菊，只产生极轻微的深浅绿花叶，甚至有时几乎无病状。小白斑病毒能在复合病情况下系统存在于豆瓣菜中是值得注意的一种现象。

The concrete work include: First, we consult a lot of herbarium specimen from PE, NAS, IFP and XJA etc.; Second, we collect more than 100 species of Brassicaceae from Xinjiang, Jilin and Shandong; Third, we study the phylogeny of Brassicaceae from China to approach some divergence on the tribe, genera and species of Brassicaceae using many ways including morphology, micromorphology and molecular systematics, furthermore, estimate the significance of every index.

2确定了两种模式植物-拟南芥与盐芥的系统学位置和系统学关系，认为两者分别归于拟南芥属和盐芥属，其亲缘关系较远，拟南芥属靠近须弥芥属、荠属、亚麻荠属、旗杆芥属、无苞芥属、糖芥属以及垂果南芥等，而盐芥属靠近山嵛菜属和沟子荠属，对于它们的深入认识，为两种模式植物在进化领域研究物种抗逆适应与趋异分化提供了一个不可多得的比较模式系统，以及更多可供比较的物种，具有重要的应用价值。

Multiple familial trichoepithelioma is inherited in autosomal dominant manner with high penetrance. The involvement of MFT in woman is more than that in man. Multiple lesions commonly present small tumors located predominantly in the nalolabial folds symmetrically. Most of the tumors are dome-shaped, skin-colored, firm

总之，毛发上皮瘤是一种高度外显的常染色体显性遗传病，女性发病多于男性，以沿鼻唇沟对称分布的乳白色半球形或圆锥形丘疹为皮损特征，无恶化趋势，组织病理为角质囊肿与肿瘤岛，同一家系中不同的患者表现度不同

Depending on intersecting channels and electro osmotic pumping, valveless switching of solvent flow is realized and the injection volume is 30 pL.

还描述了交叉点进样的方法，利用交叉形状的沟道和电场作用下的电渗流实现了溶液的无阀转换，进样体积为30pL

Several investigators have determined that placing the electrode parallel rather than perpendicular to the target nerve substantially increases the size of the lesion, thereby reducing the likelihood the treatment will miss or only partially coagulate the target nerve.234,235 After a literature review and cadaveric study, Lau et al.234 concluded the ideal electrode position is across the lateral neck of the superior articular process rather than the groove formed at the angle of the superior articular and transverse processes, as was used in most studies.159,160Other investigators have found the maximal lesion size to be reached within 60 s of lesion time,235–237 independent of whether the system is temperature or voltage controlled.238 Studies conducted in human myocardium have determined that irrigation fluid has either no effect or a slightly beneficial effect on lesion size.239 Hence, the use of LA to prevent procedure-related pain or steroid to reduce the incidence of neuritis184 should theoretically have no adverse effects on the efficacy of radiofrequency denervation.

一些研究者认为，将点击平行的置于目标神经比将其垂直置于目标神经增加了消融的范围，因而减少损伤可能使目标神经不被或部分被消融。Lau等回顾了文献中对尸体的研究，总结出理想的电极放置位置为上关节突颈部外侧而非常采用的上关节突与横突形成的沟。其他学者研究发现，不论系统是温度控制或电压控制，其最大的损伤范围都在60秒内达到。在心肌灌注的研究中，灌注液多损伤范围造成轻微或不造成损伤。因此，使用LA预防过程相关性疼痛或类固醇防止神经炎发生时，需理论上确保对射频消融效果无副作用。

The quantity of CD3+ cells in the EdNSC, AdNSC of cloning goattransplantation group and control group had no statistics difference(P＞0.05) at acute and chronic period.Overall, in our study, We got the conclusions as follow: 1,The EdNSC, AdNSCof cloning goat and the AdNSC of the non-cloning goat were successful obtained;EdNSC growed faster than AdNSC in the same cell culture method. 2,The braincontusion and laceration model of cloning goats were successful established by freefalling of 50 gram of steel ball accelerate strike on the goat brain from 100cm height.3, EdNSC and AdNSC transplantation both had obvious therapeutic effect on braincontusion and laceration of cloning goats; The therapeutic effect of EdNSCtransplantation was better. 4, Allograft of stem cells has acute and chronicimmunological rejection and autografting of stem cells has no acute and chronicimmunological rejection.

在相同的条件下，EdNSC体外培养速度比成AdNSC快。2对羊脑上薛氏沟周围运动皮层区使用50g×100 cm力度作自由落体加速撞击，可产生观察指标明确且存活率高的羊脑挫裂伤模型，有望广泛用于神经干细胞移植及药物等治疗的实验研究。3胚胎神经干细胞及成体神经干细胞移植治疗脑挫裂伤后均有较明显的治疗效果；二者相比较而言胚胎神经干细胞稍好于成体神经干细胞。4中枢神经系统异体神经干细胞移植存在着明显的免疫排斥反应，而自体神经干细胞移植基本无免疫排斥反应

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
