In this study, we report the cDNA cloning and sequence determination of Hh‐JHAMT from the seabuckthorn carpenterworm, Holcocerus hippophaecolus, by using rapid amplification of cDNA ends. The full‐length cDNA of putative Hh‐JHAMT was 1659 bp and contained a highly conserved Motif I, SAM motif I, which showed that Hh‐JHAMT like enzyme was a member of SAM‐dependent MTases. Moreover, putative Hh‐JHAMT had high homology to the other members of the JHAMT peptide family: 59% with Spodoptera litura, 54% with Bombyx mori and 54% with Helicoverpa armigera. Multiple alignments and phylogenetic analysis revealed that Hh‐JHAMT was closely related to JHAMT from Lepidoptera. Real‐time quantitative PCR experiments showed that Hh‐JHAMT mRNA expression was highest in the corpora allata (CA) complex, and was also detected at high levels during earlier larval and adult stages. The JHAMT mRNA level gradually declined during larval development, and the lowest amount of expression was observed in the pupal stage, while it increased to a higher level during adult stages. The pattern of Hh‐JHAMT expression was similar to the mode of JH biosynthesis. These results provided information concerning molecular characteristics of Hh‐JHAMT, whose expression profile suggests that the Hh‐JHAMT gene might be changed with larval development, metamorphosis and adult reproduction of the H. hippophaecolus.

A Hierarchical Model for Mobile Ad Hoc Network Performability Assessment
( Shuo Zhang ),( Ning Huang ),( Xiaolei Sun ),( Yue Zhang ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.8
Dynamic topology is one of the main influence factors on network performability. However, it was always ignored by the traditional network performability assessment methods when analyzing large-scale mobile ad hoc networks (MANETs) because of the state explosion problem. In this paper, we address this problem from the perspective of complex network. A two-layer hierarchical modeling approach is proposed for MANETs performability assessment, which can take both the dynamic topology and multi-state nodes into consideration. The lower level is described by Markov reward chains (MRC) to capture the multiple states of the nodes. The upper level is modeled as a small-world network to capture the characteristic path length based on different mobility and propagation models. The hierarchical model can promote the MRC of nodes into a state matrix of the whole network, which can avoid the state explosion in large-scale networks assessment from the perspective of complex network. Through the contrast experiments with OPNET simulation based on specific cases, the method proposed in this paper shows satisfactory performance on accuracy and efficiency.

With the development of Internet technology, electronic commerce shows the vigorous vitality; along with the popularity of a mobile phone and network operator’s technology, electronic commerce began to develop online mode. According to the "2013 annual Chinese e-commerce market data monitoring report", until the December of 2013, trading in e-commerce market scale is 10.2 trillion yuan, grows 29.9% compared to the same period. The online retail market scale is 18851 billion yuan, a year-on-year growth of 42.8%. However, this data only accounted for 8.04% of the total retail sales of social consumer goods, while there are 91.96% lines which are waiting for developing. The biggest advantage of the O2O(online to offline) is it can be introduced the consumers to offline trading. The current O2O e-commerce in China is still in the initial stage of development, there are challenges and opportunities .If the network of electronic commerce and the entity shop retailers can seize the opportunity, and be acknowledged of what the consumers want and need, make full use of large data analysis, he will be successful. Firstly, this paper explains the purpose and significance of the topic, underlining the present internet background and the status of e-commerce in the Internet environment, analyzing the current situation O2O faces, besides, we give some analysis of the O2O mode and summarize the advantages of him. Secondly, through the analysis of 19e O2O, we find the problems in the process of its development. Then, through the example of 19e, we find the problem and deficiency in the development of Chinese O2O. Finally, we summarize it and give some expectations of the O2O’s development in the future.

Objective: To investigate the effects of secondary left-sided portal hypertension (LSPH) on the radical operation rate of patients with pancreatic cancer and systemically evaluate the prognosis of patients with LSPH secondary to pancreatic cancer after radical surgery. Materials and Methods: The data of patients with pancreatic cancer who underwent laparotomy over a 15-year period in Department of Hepatobiliary Surgery of Chinese PLA Air Force General Hospital from Jan. 1, 1997, to Jun. 30, 2012 was retrospectively reviewed. Results: A total of 362 patients with pancreatic cancer after laparotomy were selected, including 73 with LSPH and 289 without LSPH. Thirty-five patients with LSPH (47.9%) and 147 without non-LSPH (50.9%) respectively underwent radical operations. No significant difference was found between these two groups regarding the total resection rate and stratified radical resection rate according to different pathological types and cancer locations. The mean and median survival time of patients after radical operation in LSPH group were $13.9{\pm}1.3$ months and 14.8 months, respectively, while those in non-LSPH group were $22.6{\pm}1.4$ months and 18.4 months, respectively(P<0.05). Conclusions: Radical operations for pancreatic cancer and secondary LSPH are safe and effective. Because high-grade malignancy and poor prognosis are closely associated, the decision for radical surgery should be made more meticulously for the patients with pancreatic cancer.

Clinical Significance of SH2B1 Adaptor Protein Expression in Non-small Cell Lung Cancer
Zhang, Hang,Duan, Chao-Jun,Chen, Wei,Wang, Shao-Qiang,Zhang, Sheng-Kang,Dong, Shuo,Cheng, Yuan-Da,Zhang, Chun-Fang Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.5
The SH2B1 adaptor protein is recruited to multiple ligand-activated receptor tyrosine kinases that play important role in the physiologic and pathologic features of many cancers. The purpose of this study was to assess SH2B1 expression and to explore its contribution to the non-small cell lung cancer (NSCLC). Methods: SH2B1 expression in 114 primary NSCLC tissue specimens was analyzed by immunohistochemistry and correlated with clinicopathological parameters and patients' outcome. Additionally, 15 paired NSCLC background tissues, 5 NSCLC cell lines and a normal HBE cell line were evaluated for SH2B1 expression by RT-PCR and immunoblotting, immunofluorescence being applied for the cell lines. Results: SH2B1 was found to be overexpressed in NSCLC tissues and NSCLC cell lines. More importantly, high SH2B1 expression was significantly associated with tumor grade, tumor size, clinical stage, lymph node metastasis, and recurrence respectively. Survival analysis demonstrated that patients with high SH2B1 expression had both poorer disease-free survival and overall survival than other patients. Multivariate Cox regression analysis revealed that SH2B1 overexpression was an independent prognostic factor for patients with NSCLC. Conclusions: Our findings suggest that the SH2B1 protein may contribute to the malignant progression of NSCLC and could offer a novel prognostic indicator for patients with NSCLC.

The n-dimensional generalized Hartogs triangles ℍ<sup>n</sup><sub>𝐩</sub> with n ≥ 2 and 𝐩 := (p<sub>1</sub>, …, p<sub>n</sub>) ∈ (ℝ<sup>+</sup>)<sup>n</sup> are the domains defined by ℍ<sup>n</sup><sub>𝐩</sub> := {z = (z<sub>1</sub>, …, z<sub>n</sub>) ∈ ℂ<sup>n</sup> : |z<sub>1</sub>|<sup>p<sub>1</sub></sup> < ⋯ < |z<sub>n</sub>|<sup>p<sub>n</sub></sup> < 1}. In this paper, we study the L<sup>p</sup> Sobolev mapping properties for the Bergman projections on the n-dimensional generalized Hartogs triangles ℍ<sup>n</sup><sub>𝐩</sub>, which can be viewed as a continuation of the work by S. Zhang in [25] and a higher-dimensional generalization of the work by L. D. Edholm and J. D. McNeal in [16].
