Speculating on the origin of Gaultheria, two different hypotheses were suggested, one of Gondwanan origin, and the other of Laurasian origin In the present paper, recent advances in molecular phylogenetics and biogeography of Gaultheria are summarized and some problematical issues within the genus discussed.

关於白珠树属的起源问题存在两种不同的推测：一种观点认为该属起源於南半球的冈瓦纳古陆；另一种观点则认为其起源於北半球的劳亚古大陆。本文概述了近年来白珠树属的分子系统学和生物地理学研究进展，并对该属尚存的一些问题进行了讨论。

Objective:To investigate the relation between the incidence rates of ventricular premature beats from different original positions and the electrophysiological heterogeneity of myocardial cell.

目的：研究不同起源部位室性早搏发生率与心室肌细胞电生理异质性的关系。方法：应用12导联同步动态心电图检测482例室性早搏患者，计算各起源部位室性早搏发生率。

Based on the study of 120 cultivated herbaceous peonies and 8 wild species native to China, the relationship among them was firstly investigated, and the result indicated that 4 narrowly-distributed wild species involving Paeonia sinjiangensis K. Y. Pan, P. anomala L., P. emodi Wallich ex Royle and P. sterniana Fletcher have no chance to be the ancestor of Chinese cultivated herbaceous peonies. Then the difference and similarity existed in the root, leaves and flowers of the wild species and cultivars was exhaustively compared and it is concluded by the equivalent affinity between P. lactiflora Pall. and the cultivars.

以原产我国的120个栽培品种和8个野生种为主要研究对象，首先根据地理分布的差异对栽培芍药与各个野生种的亲疏关系进行了分析探讨，表明新疆芍药、块根芍药、多花芍药和白花芍药等4个窄布种不可能参与我国芍药品种的栽培起源；然后对栽培品种和各野生种之间的根、叶及花等性状的差异进行了细致的比较分析，进一步证明川赤芍亦不可能参与我国栽培芍药品种的起源，草芍药和美丽芍药等2个种对我国栽培芍药的起源影响甚微。

Combining the available regional geological and geophysical research, the petrogenesis of the magmatism was studied. As a response and absorption to the IndiaAsia collision, the northeastward flow of the asthenosphere beneath the Tibetan Plateau along the 400 km depth interface was blocked by the North China craton, and caused a systemic sequences in West Qinling Region, including the strikeslip fault systems and pullapart basins in the shallow crust and the origin of the twotype magmatism in this work in deep lithosphere. This explanation is consistent with the lithology and plumelike geochemical features of the kamafugite and potassic trachybasalt, which are significantly different from the potassic magmatism within the plateau and its adjacent regions.

结合前人对该区深部地球物理和断裂构造的研究，论证了火山岩的起源与成因，指出作为对印度-欧亚大陆强烈碰撞的吸收与调节，高原下软流圈地幔流沿400 km界面向北东方向的侧向流动以及西秦岭周边克拉通块体的阻挡，是形成西秦岭断裂系左行走滑特征和巨大拉分盆地的主要原因，也是导致西秦岭新生代两类钾质火山岩和碳酸岩起源与成因的动力学机制，较好地解释了西秦岭新生代岩浆作用起源深度大，具有地幔柱源的地球化学特征，岩石组合与地球化学有别于高原内部及其周边地区新生代钾质火山岩的原因。

The origin that he has is "Consumption", which was awakened by Araya Souren and since then he has been eating people and selling drugs on the street that he had grown himself.
