ABSTRACT
Ranae Oviductus has a good tonic effect and is commonly used for both medicine and food. The use of Ranae Oviductus was confused because the origin of Ranae Oviductus was roughly recorded in ancient herbal literatures. In order to clarify the confusing literatures and trace the origin of Ranae Oviductus，this paper conducted a textual research on the name，origin，distribution，harvesting and processing，efficacy of the Chinese medicine by consulting ancient herbal books，modern literatures and monographs of traditional Chinese medicine. The results of the textual research showed that Ranae Oviductus belongs to Manchu medicine，which was first applied by the Manchu people because of its tonic effect. The original animal of Ranae Oviductus has many names，which are all translated from Manchu language. By analyzing the descriptions of Ranidae in various herbal books，it is concluded that the earliest description of the original animals of Ranae Oviductus appeared in the Shengjing Tongzhi compiled by Agui in the Qing dynasty. After summarization of the taxonomic changes of some species of Rana，the original animals of Ranae Oviductus were preliminarily determined as Rana dybowskii，R. amurensis and R. huanrenensis. We excluded R. huanrenensis by its size and R. amurensis by its poor quality. Therefore，the original animal of Ranae Oviductus is R. dybowskii，the main production area is northeast China and the best capture time is in October. Ranae Oviductus is often eaten after being stewed. The study can provide the effective basis for the identification of the original animal of Ranae Oviductus，the distribution of production area and the utilization of resources.
ABSTRACT
Objective:To identify 24 <italic>Rana</italic> species such as <italic>Rana dybowskii</italic> by mitochondrial cytochrome C oxidase subunit I （<italic>CO</italic>Ⅰ） gene-based DNA barcoding and build the neighbour-joining （NJ） tree for hierarchical cluster analysis， so as to provide a basis for the identification and classification of <italic>Rana</italic> species as well as the discovery of new species. Method:<italic>R. dybowskii</italic>， <italic>R. chensinensis</italic>， <italic>R. amurensis</italic>， <italic>R. culaiensi</italic>s， and <italic>R. huanrenesis</italic>， ten for each species， were collected for DNA extraction and polymerase chain reaction （PCR） amplification<italic> </italic>and sequencing. A total of 50 <italic>CO</italic>Ⅰ gene sequences were obtained. Then 163 <italic>CO</italic>Ⅰ gene sequences for 24 species of <italic>Rana</italic> and one <italic>CO</italic>Ⅰ gene sequence for <italic>Pelophylax</italic>，<italic> Odorrana</italic>， <italic>Nidirana</italic>， <italic>Hylarana</italic>， and <italic>Amolops</italic> were harvested from GenBank. After sequence alignment by MEGA X， the parsimony-informative sites of <italic>CO</italic>Ⅰ gene sequences were analyzed and the intraspecific and interspecific genetic distances were calculated， followed by the built of NJ tree and hierarchical cluster analysis. Result:The <italic>CO</italic>Ⅰ gene sequences of 24<italic> Rana</italic> species including <italic>R. dybowskii</italic> were 554 bp in length and there were 210 parsimony-informative sites in total. The intraspecific genetic distance of each species was smaller than 2%. Except that the interspecific genetic distance between <italic>R. sangzhiensis</italic> and <italic>R. zhengi</italic> was 0.004， the genetic distances between the other species ranged from 0.024 to 0.228. <italic>R. sangzhiensis</italic> and <italic>R. zhengi</italic> were clustered into one branch and some <italic>R. dybowskii</italic> and <italic>R. uenoi</italic> into one branch. There were two separate branches for <italic>R. chensinensis</italic> and the other species were all clustered independently. Conclusion:<italic>CO</italic>Ⅰ-based DNA barcoding enabled the identification of 24 species of <italic>Rana</italic> including <italic>R.dybowskii</italic>. The findings supported that <italic>R. sangzhiensis</italic>， <italic>R. zhengi</italic>， <italic>R. coreana</italic>， and <italic>R. kunyuensis</italic> were the same species. One branch of <italic>R. chensinensis </italic>might be one of the four undownloaded species in Ranidae or a new species. The results have demonstrated that <italic>CO</italic>Ⅰ-based DNA barcoding allows not only the identification of 24 species of Rana including <italic>R. dybowskii </italic>but also the classification of ranidae species and the discovery of new species or subspecies.
ABSTRACT
This paper summarized nursing experience of 14 patients with idiopathic pulmonary artery hypertension (IPAH)combined with left heart failure after lung transplantation.The key points of nursing included:dynamic evaluation and maintenance of cardiac function,close monitoring and control,management of extra-corporeal membrane oxygenation,mechanical ventilation and sequential non-invasive ventilation,early ambulation and rehabilitation.All 14 patients recovered and were discharged successfully.
