Genus Rhacophorus Kuhl and Van Hasselt, 1 822 is one of the most diverse genera of the family Rhacophoridae, and its taxonomy of genus Rhacophorus faces major challenges because of rapidly described new species and complex interspecies relations. In this study, we investigate the generic taxonomy within the genus Rhacophorus based on 1 972 bp of mitochondrial genes(12S rRNA, tRNA-val and 16S rRNA), containing 102 sequences from 58 species. The results reveal three well-supported and highly diverged matrilines that correspond with morphological characteristics and geographic distribution. Accordingly, we consider these three lineages as distinct genera: Rhacophorus sensu stricto, resurrected genus Leptomantis Peters, 1867, and the genus Zhangixalus gen. nov.

目的建立测定人血浆中丙泊酚浓度的方法并应用于淋巴水肿患者血药浓度检测。方法以麝香草酚为内标,血浆样品经蛋白沉淀后,采用超高效液相色谱-串联质谱(UPLC-MS/MS)法测定丙泊酚的浓度。以Kinetex C18为色谱柱,以乙腈(A)-水(B)为流动相进行梯度洗脱,流速为200μL/min,进样量为5μL,柱温为40℃,样品仓温度为15℃。采用多反应监测模式进行检测,用于定量分析的离子对为m/z 177.0→161.2(丙泊酚)、m/z 149.0→133.1(内标)。采用上述方法测定6例淋巴水肿患者血浆中丙泊酚的血浆浓度。结果丙泊酚检测质量浓度的线性范围为50~5000 ng/mL(r=0.9950);批内、批间精密度的RSD均不高于8.08%;空白血浆中无内源性干扰;无残留效应和稀释效应;提取回收率为89.80%~93.73%,基质效应为97.93%~101.73%;稳定性试验的RSD均小于3.27%。术中靶控输注2~30 min内,6例患者的丙泊酚血药浓度为1865.3~6056.2 ng/mL,停药后4~8 h内基本代谢完全。结论所建UPLC-MS/MS法可以在不进行衍生化的前提下,实现对丙泊酚的测定,样品前处理过程简便、快速,可用于淋巴水肿患者血浆样本中丙泊酚的血药浓度检测。

The exchange of biotas between Eurasia and North America across the Bering land bridge had a major impact on ecosystems of both continents throughout the Cenozoic. This exchange has received particular attention regarding placental mammals dispersing into the Americas, including humans after the last glacial period, and also as an explanation for the disjunct distribution of related seed plants in eastern Asia and eastern North America. Here, we investigate bi-directional dispersal across the Bering land bridge from estimates of dispersal events based on time-calibrated phylogenies of a broad range of plant, fungus and animal taxa. We reveal a long-lasting phase of asymmetrical biotic interchange, with a peak of dispersal from Asia into North America during the late Oligocene warming(26–24 Ma), when dispersal in the opposite direction was greatly decreased. Influx from North America into Asia was lower than in the opposite direction throughout the Cenozoic, but with peak rates of dispersal at the end of the Eocene(40–34 Ma)and again in the early to middle Miocene(16–14 Ma). The strong association between dispersal patterns and environmental changes suggests that plants, fungi and animals have likely dispersed from stable to perturbed environments of North America and Eurasia throughout the Cenozoic.
