Aimed to evaluate the phylogenetic position of the recently described Protobothrops dabieshanensis Huang et al. （2012）, phylogenic relationships of 12 species within Protobothrops based on four mtDNA gene fragments （12S RNA, 16S RNA, ND4 and Cyt b） were reconstructed in our study. The result indicates a clade composed ofP dabiesha- nensis, P. jerdonii and P xiangchengsis with strong support. The genetic distance among P dabieshanensis, P jerdonii and P xiangchengsis was much lower than other congeners. Based on the data from the phylogenetic analysis and pre- viously described morphological differences, we conclude that P dabieshanensis is a valid species with close affinities to P jerdonii and P xiangchengsis.

During a biological survey in July 2011, a pit viper was collected from the Yaoluoping Nature Reserve in the Dabie Mountains, Anhui, China. The pit viper’s the total length measured 836 mm with a dorsal ground color of yellowbrown, decorated by 56 dark-brown transverse bands. The 4thsupralabial squama of the new species is separated from subocular by two squamae, and the tip of tail is orange; this combination of characters distinguish it from other species of the genus Protobothrops. Based on the body proportions, number of squamae, body color pattern, and comparing the data of its life history with those of other species of Protobothrops, we herein describe it as a new species, belonging to the genus of Protobothrops.

Background Anterior glottic web is one type of laryngeal stenosis.Previous surgical methods had some drawbacks,such as large surgical trauma,long postoperative recovery time,and multiple-stage surgery.This study aimed to explore better treatment to repair anterior glottis web.Methods We performed vocal cord mucosal flap procedure on 32 patients with anterior laryngeal webs.All subjects received vocal cord scar releasing and vocal cord mucosal flap repair and suture under general anesthesia with selfretaining laryngoscope.Results All 32 patients completed surgery in one stage,without postoperative laryngeal edema,difficulty in breathing,or other complications.After the surgery,the anterior commissure of vocal cords recovered to a decent triangle shape in 28 patients; however,in four patients there were 2 to 3 mm adhesion residuals on the anterior ends of the vocal cords,accompanied by scar appearance of bilateral vocal cords.The GRB score,voice handicap index scores,and maximum phonation time score significantly improved in all patients after the surgery.There was no evidence of recurrent laryngeal webbing in the 6-rnonth follow-up.Conclusion Vocal cords mucosal flap repair surgery has the advantages of less trauma,quick recovery,and significant improvement of the voice in the treatment of laryngeal webs.

观照王朝闻美学和艺术学研究的“深层精神支撑结构”,有助于更切实地体会其在当代学术生态系统中所发挥的独特作用。所谓“深层精神支撑结构”,指在学术讨论过程中,对学者的立场选择和观点取舍发挥基本定位作用的内在精神驱动力,包括基于特定主体气质所形成的对于理论品格的个性化追求、研究过程中特有的方法论偏好、思想及表述过程中惯常依托的程式化结构、处理自我目标指向与外在环境反应之间博弈关系时的策略类型等多种精神要素。在与同时代其他美学家的比较性视野中,王朝闻的研究呈现出如下几个方面的特征,即理论品格的“谦抑性”、研究方法的“经验性”、思想过程的“对话性”和目标指向的“妥协性”。

Background Quantitative dynamic contrast enhancement MR imaging （DCE-MRI）,used to measure properties of tissue microvasculature and tumor angiogenesis,is a promising method for distinguishing benign and malignant tumors and characterizing tumor response to antiangiogenic treatment.The aim of this study was to assess the feasibility of quantitative parameters derived from clinically used DCE-MRI for distinguishing benign from malignant tumors in the sinonasal area,which may be potentially useful for prediction and monitoring of treatment response to chemoradiotherapy of sinonasal tumors.Methods One hundred and forty-three patients with sinonasal tumors,including 78 malignant tumors and 65 benign tumors and tumor-like lesions,underwent clinically used DCE-MRI.Parametric maps were obtained for quantitative parameters including Ktrans,kep and ve.Two radiologists reviewed these maps and measured Ktrans,kep and ve in the tumor tissue.Data were analyzed using independent T-test or Mann-Whitney U test analysis and receiver operating characteristic curves.Results Ktrans,kep and ve showed significant differences between benign and malignant tumors in the sinonasal area （P=-0.000 1）.The accuracy of Ktrans,kep and ve in differentiation between benign and malignant sinonasal tumors were 72.0％,76.2％ and 67.1％,respectively.There were significant differences in kep and ve between malignant epithelial sinonasal tumors and lymphomas （P ＜0.05）.Using a ve value of 0.213 as the threshold value differentiated malignant epithelial tumors from lymphomas with an accuracy of 78.3％,sensitivity of 88.2％,specificity of 68.0％,positive predictive value of 66.7％,and negative predictive value of 90.9％.However,no significant difference in Ktrans and kep was found between malignant epithelial and non-epithelial tumors in the sinonasal area （P ＞0.05）.Conclusions It is feasible that quantitative parameters of tumors can be derived from clinically used DCE-MRI in the sinonasal region.Preliminary findings suggest an increased value for quantitative DC
