Asian leaf-litter toads of the genus represent charismatic anuran diversification with 80 species, of which 25 are from China. Recent new discoveries suggest that the diversity of this genus is underestimated. Here, we describe a new species of , from the Basha Nature Reserve, Congjiang County, Guizhou Province, China. The new species is distinguished from its congeners by the following suite of morphological traits: small body size (SVL 22.9-25.6 mm in six adult males and 27.1 mm in one adult female); head longer than wide; dorsal skin slightly shagreened with small tubercles; creamy-white chest and belly with irregular black spots; distinct ventrolateral glands forming a white line; finger webbing and fringes absent; toe webbing rudimentary and lateral fringes narrow; iris bicolored with bright orange in upper half and silver in lower half; dorsal surface of tadpole head dark brown with small, brown, irregular spot, air sac-shaped bulges on both sides of body. The new species differs from all known congeners by an uncorrected -distance of >5.3% of the 16S rRNA gene fragment examined, and the phylogenetic analysis clusters the new species with and . At present, the new species is only known from a small range of montane evergreen secondary forests in Basha Nature Reserve approximately 900 m elevation. Its natural history and conservation status are discussed.

Complete mitochondrial genome of the sharp-snouted pitviper (Reptilia, Viperidae).

Mitochondrial DNA B Resour 2019 Sep 5;4(2):2900-2901. Epub 2019 Sep 5.

College of Life and Environment Sciences, Huangshan University, Huangshan, P. R. China.

The sharp-snouted pitviper, , belongs to the monotypic genus of the family Viperidae. It is one of the important species of snakes for its commercial and medicinal value. Complete mitochondrial genome sequence of the . was sequenced by next-generation sequencing technology. The total mitochondrial genome is 17,538 bp in length, containing 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes, and 2 control regions. Most of the genes of . are encoded on the H-strand, except for the ND6 subunit gene and eight tRNA genes which distribute on the L-strand. Phylogenetic reconstruction result indicated that our newly determined mitochondrial genome sequence could meet the demands. The complete mitochondrial genome sequence presented here will be useful to study the evolutionary relationships and genetic diversity of . .

The complete mitochondrial genome of (Reptilia: Scincidae).

Mitochondrial DNA B Resour 2019 Jul 23;4(2):2727-2728. Epub 2019 Jul 23.

College of Life and Environment Sciences, Huangshan University, Huangshan, P.R. China.

The complete mitochondrial genome (mitogenome) sequence of was sequenced and characterized by next-generation sequencing technology. The total length of mitogenome is 17,027 bp and contains 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes, and 2 non-coding regions (the control region and the putative L-strand replication origin). Most of the genes of are encoded on the H-strand, except for the ND6 subunit gene and 8 tRNA genes which is distributed on the L-strand. Phylogenetic reconstruction suggested that is the sister group of the . within the genus . The complete mitochondrial genome sequence presented here will be useful to study the evolutionary relationships and genetic diversity of .

The Papenfuss' Rock Agama is an endemic species in the Tibet Autonomous Region of China. The complete mitochondrial genome sequence of this species was determined by shotgun sequencing. The total length of mitogenome is 17,005 bp and its base composition was 37.3% for A, 23.9% for T, 12.5% for G, and 26.3% for C, which contains 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes, and 2 control regions. The phylogenetic tree of . and 15 other related species was reconstructed using maximum likelihood (ML) methods. The mitogenome sequence presented here will be useful to understand the phylogenetic relationships of .

[Application of fingerprint identification technology in EMR system].

Zhongguo Yi Liao Qi Xie Za Zhi 2009 Mar;33(3):172-5

Department of Electronic Science & Technology, University of Science & Technology of China, Hefei, 230027.

Based on the deep analysis of existing fingerprint identification algorithms, this article proposes an integrative solution to adopt the fingerprint identification technology into EMRS Electronic Medical Records System. It may improve the security of EMRS and raise the working efficiency of physicians effectively.

[A method to enhance user experience of EMR based on mining association rules of incremental updating data].

Zhongguo Yi Liao Qi Xie Za Zhi 2009 Mar;33(2):83-6, 149

Department of Electronic Science and Technology, University of Science and Technology of China, Hefei 230027, China.

The user experience (EX) of current Electronic Medical Record systems (EMR) is needed to improve. This paper proposed a new method to enhance EX of EMR. Firstly, system template and text characterization are used to make the EMR data structured. Then, the structured date are mined based on mining the association rules of incremental updating data to find the association of the elements of template of EMR and the values of elements. Finally, with the help of mined results, the users of EMR are able to input data effectively and quickly.
