Wen‐Bo Li,Naiyi Liu,Qin XU,Min Sun,Jie Fang,Shuyan Wang 한국곤충학회 2019 Entomological Research Vol.49 No.2

The sensilla type, number and distribution in male and female adults of Carabus elysii Thomson, 1856 (Coleoptera: Carabidae) were studied using scanning electron microscopy. The results showed that there are seven categories and 12 types of sensilla in C. elysii adults: three types of S.Ch, three types of S.T, two types of S.B and one each of B.B, S.Co, S.Ca and S.Cam. There is no difference between male and female in the types of sensilla. Apart from the significant difference in the number and distribution of S.B.2, S.Co and S.Ca between male dorsal and ventral surfaces, there are no significant differences between male and female antennae. In general, the number of sensilla in females is larger than that in males. The results provide a basic reference for future ultrastructure, electrophysiological, and comparative behavioral studies of Carabus species.

Liu, Meng-Xue,Li, Jian,Geng, Yun-Long,Wang, Yan-Chun,Li, Jie,Chen, Yu-Juan,Ali, Gholam,Tarver, Siobhan L.,Wen, Yu-Feng,Sun, Wen-Jie Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.24

Background: This study aimed to understand the relationship between knowledge level and behavior on breast care in Chinese students, so as to provide strategies for improving the health education of breast care and subsequently for aiding in breast cancer prevention. Materials and Methods: A self-designed questionnaire was used to evaluate breast care knowledge level and characterize related behavior. Correlation analysis was conducted for the knowledge level and behavior. The study was carried out using 597 female undergraduate students in medical and non-medical colleges in Wuhu, China. Results: The average score of breast care knowledge was $5.32{\pm}1.68$ ($5.62{\pm}1.68$ and $5.00{\pm}1.68$ for medical and non-medical students, respectively), with a greater score value for sophomores ($5.59{\pm}1.72$) than freshmen ($5.18{\pm}1.65$). The average score of breast care behavior was $2.21{\pm}1.13$, again with a greater value in sophomores ($2.37{\pm}1.15$) than freshmen ($2.21{\pm}1.13$). A significant positive correlation (r=0.231, p<0.01) between knowledge scores and behavior scores was observed. In addition, various factors, including paying attention to breast care information, receiving breast self-examination guidance, TV program and Internet, were found to influence breast care knowledge. Conclusions: In general, female undergraduate students lack of self-awareness of breast care with a low rate of breast self-examination. It is necessary to carry out health education to improve early detection of breast cancer.

Zhu, Wen-Wen,Kang, Li,Gao, Ya-Ping,Hei, Yan,Dong, Jie,Liu, Yu,Xiao, Li-Hua,Yang, Guang Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.11

Objective: To investigate whether the expression level of valosin-containing protein (VCP) is correlated with the prognosis of primary orbital mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: VCP expression in 58 samples from primary orbital MALT lymphoma patients was determined by immunohistochemisty using monoclonal antibodies. Correlations between VCP expression level and prognosis were clarified by statistical analysis. Results: It was found that the percentage of VCP positive cells in samples of primary orbital MALT lymphoma ranged from 32% to 95%. The samples were divided into two groups (level 1 and level 2) according to the median value (45%) of the percentage of VCP positive cells. It was found that the expression level of VCP was significantly correlated with recurrence (P=0.003) and tumor size (P=0.008). At the same time, the 5-year disease-free and overall survival rate of patients of level 1 was significantly better than that of level 2 (P=0.001; P=0.032). There was no observed correlation between the expression level of VCP and other clinical features. Conclusion: VCP could be a useful marker for predicting the prognosis of primary orbital MALT lymphoma.

劉文杰 ( Liu Wen-jie ),諸慧琴 ( Zhu Hui-qin ) 단국대학교 법학연구소 2019 법학논총 Vol.43 No.4

부정경쟁행위가 인터넷환경의 전반에 만연되면서 인터넷 부정경쟁이 형성되고 있다. 본 연구는 우선 연구대상을 한정하여 부정경쟁행위를 전통형과 신형 두 부류로 구분하였다. 그리고 이들의 구체적인 표현형식을 소개하고, 부정경쟁 행위의 피해, 인터넷 부정경쟁행위의 특징을 설명하였다. 그리고, 중국의 부정경쟁행위의 법률제도의 미비점을 분석한 후, 최종 부정경쟁방지 법이 인터넷 시대에 적용 시 나타나는 어려움을 분석한다. 해외의 반부정행위의 실천상황을 소개하고 성문법과 실천법 차원에서 미국의 인터넷 부정경쟁행위에 대한 법률제도와 독일·일본의 부정경쟁방지법의 관련 규정을 소개하였다. 본 연구는 중국의 인터넷 부정경쟁행위의 법제도의 부족한 점을 분석하였으며, 각각 주체의 적용범위확대, 관련 법률의 개정 및 구체적인 인터넷 부정행위에 대한 규제라는 세 가지 큰 측면에서 중국 인터넷 부정경쟁행위의 법을 보완하였다. 그 중에서도 세부사항의 의견을 제시하였다. 예를 들어, 일반 조항은 원칙적인 규정에 속하며, 부정경쟁행위의 인정에 대해서는 상세한 해석을 제공하지 않아 지나치게 추상적이다. 현재 많은 국가에서 일반 조항이 열거된 입법모델을 선택하고 있다. 인터넷 자기단속 조례의 수립하여 시장이 능동적으로 인터넷상의 부정경쟁행위를 억제하도록 한다. 규제에 대한 구체적인 의견 제시를 통해 연구의 실천적 의의를 갖는다. Unfair competition has spread to the whole network era and formed the network unfair competition. Firstly, the article defines the research object, divides the unfair competition into two types, traditional and new, introduces their specific manifestations respectively, reveals the harm of the network unfair competition, summarizes the characteristics of the network unfair competition, and analyzes the deficiencies of China’s legal system to regulate the network unfair competition. Then, it analyzes the disadvantages of the “Anti-Unfair Competition Law” applied to the network market, introduces the judicial practice of the country in regulating foreign anti-unfair acts, introduces the legal system of the United States in regulating network unfair competition acts from the perspective of statute law and case law, and introduces some relevant provisions of the “Anti-Unfair Competition Law” of Germany and Japan. The fourth part of this article is the core content, which analyzes the deficiencies of China’s legal system to regulate the network unfair competition behavior, and perfects China’s legal system to regulate the network unfair competition behavior from three major aspects: expanding the scope of application of the main body, amending relevant laws and regulations, and regulating specific network unfair behavior. Among them, opinions are also put forward from some minor aspects. For example, the general provisions are principled provisions, which do not provide a more detailed explanation for the identification of unfair competition acts. These provisions are too abstract and have no pertinence. At present, many countries choose the legislative mode listed in the general provisions, and in the anti-unfair laws, specifying some harmful and typical unfair competition acts can improve the judicial efficiency. The establishment of a network self-restraint treaty, the mobilize initiative of the market, to resist acts of unfair competition on the network. In addition, specific suggestions on regulation are put forward to strengthen the practical significance of the article.

Correlation between population size of pear Psylla (Cacopsylla chinensis) and leaf structure features in different pear cultivars

Sheng-jie Xu,Lun Wu,Qi Zhi Liu,Jun Liu,He Wang,Jie-wen Wang,Ting Zhang 한국응용곤충학회 2019 Journal of Asia-Pacific Entomology Vol.22 No.2

The feeding preference of pear psylla (Cacopsylla chinensis) varies among pear cultivars. To clarify whether leaf structural factors are related to C. chinensis resistance, eleven pear cultivars of three pear species and their hybrids in China were studied. The population size of C. chinensis in plots of different cultivars was investigated, and leaf paraffin sections of each pear cultivar were observed. Correlation analysis results showed that the thickness of palisade tissue (PT) and the thickness ratio (TR) of PT to leaf (L) were the main factors influencing resistance to C. chinensis. The leaves of cultivar Wujiuxiang and those species from France and the USA exhibited the thickest PT and the highest TR; these three cultivars demonstrated much higher resistance to C. chinensis than did the other cultivars. The cultivar Gold Nijisseiki, with a large C. chinensis population size, showed low PT and TR. The findings of this study may provide valuable information to pear growers, experts and scientists regarding plant protection, cultivation and breeding when selecting suitable varieties to culture from the perspective of pest control.

Three-Port Laparoscopic Exploration is not Sufficient for Patients with T4 Gastric Cancer

Huang, Hua,Jin, Jie-Jie,Long, Zi-Wen,Wang, Wei,Cai, Hong,Liu, Xiao-Wen,Yu, Hong-Mei,Zhang, Li-Wen,Wang, Ya-Nong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.19

Gastric cancer continues to be a leading cause of cancer death. The majority of patients with gastric adenocarcinoma in China present with advanced disease. Ruling out unresectable cancers from an unnecessary "open" exploration is very important. The aim of this study was to assess the value of five-port anatomical laparoscopic exploration in T4 gastric cancer in comparison with three-port laparoscopic exploration and laparotomy exploration. We conducted a retrospective study on 126 patients with T4 stage scheduled for D2 curative gastrectomy based on computed tomography (CT) staging at Department of Gastric Cancer and Soft Tissue Sarcoma, Fudan University Shanghai Cancer Center, from Apr. 2011 to Apr. 2013. Laparotomy exploration (Group I), three-port laparoscopic exploration (Group II) or five-port anatomical laparoscopic exploration (Group III) were performed prior to radical gastrectomy. Accuracy rate for feasibility of D2 curative gastrectomy in laparotomy exploration and five-port anatomical laparoscopic exploration groups was higher than that in the three-port laparoscopic exploration group. Five-port anatomical laparoscopic exploration group had the highest accuracy resection rate (Group I vs Group II vs Group III,92.6% vs78.6% vs 97.7%; p<0.05) and shorter length of hospitalization (Group I vs Group II vs Group III, $9.58{\pm}4.17$ vs $6.13{\pm}2.85$ vs $5.00{\pm}1.81$; p<0.001). Three-port laparoscopic exploration has low accuracy rate for assessing feasibility of D2 curative gastrectomy and five-port anatomical laparoscopic exploration should be performed on patients with T4 gastric cancer.

Effects of Variants in Proopiomelanocortin and Neuropeptide Y Genes on Growth, Carcass, and Meat Quality Traits in Rabbits

Liu, Wen-Chao,Chen, Shi-Yi,Jia, Xian-Bo,Wang, Jie,Lai, Song-Jia Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.5

Appetite-related neuropeptides proopiomelanocortin (POMC) and Neuropeptide Y (NPY) are essential for regulating feeding behavior and energy homeostasis. The objective of this study was to evaluate the effects of variants in POMC and NPY genes on growth, carcass and meat quality traits in rabbits. A total of six SNPs were identified for POMC (n = 2) and NPY (n = 4) genes by direct sequencing. Three SNPs were subsequently genotyped by using MassArray system (Sequenom iPLEXassay) in 235 individuals, which belong to three meat rabbit breeds, including 93 Ira rabbits; 81 Champagne rabbits and 61 Tianfu black rabbits. The SNP c.112-12G>T was in intron-exon boundaries (intron 1) of POMC gene, and the association analysis showed that individuals with TT genotype had a greater 84 d body weight (BW84), eviscerated weight and semi-eviscerated weight than those with GT genotype (p<0.05); the TT individuals were also higher than those GG in the ripe meat ratio (RMR) (p<0.05). The g.1778G>C SNP, which was in complete linkage with other three SNPs (g.1491G>A, g.1525G>T and g.1530C>T) in intron 1 of NPY gene, was significantly correlated with eviscerated slaughter percentage and semi-eviscerated slaughter percentage in rabbits, and the individuals with CC genotype had a better performance than CG genotype (p<0.05). These findings would provide primary clues for the biological roles of POMC and NPY underlying the rabbit growth-related traits.

Nanosized Carbon Black Combined with Ni₂O₃ as “Universal” Catalysts for Synergistically Catalyzing Carbonization of Polyolefin Wastes to Synthesize Carbon Nanotubes and Application for Supercapacitors

Wen, Xin,Chen, Xuecheng,Tian, Nana,Gong, Jiang,Liu, Jie,Rü,mmeli, Mark H.,Chu, Paul K.,Mijiwska, Ewa,Tang, Tao American Chemical Society 2014 Environmental science & technology Vol.48 No.7

<P>The catalytic carbonization of polyolefin materials to synthesize carbon nanotubes (CNTs) is a promising strategy for the processing and recycling of plastic wastes, but this approach is generally limited due to the selectivity of catalysts and the difficulties in separating the polyolefin mixture. In this study, the influence of nanosized carbon black (CB) and Ni<SUB>2</SUB>O<SUB>3</SUB> as a novel combined catalyst system on catalyzing carbonization of polypropylene (PP), polyethylene (PE), polystyrene (PS) and their blends was investigated. We showed that this combination was efficient to promote the carbonization of these polymers to produce CNTs with high yields and of good quality. Catalytic pyrolysis and model carbonization experiments indicated that the carbonization mechanism was attributed to the synergistic effect of the combined catalysts rendered by CB and Ni<SUB>2</SUB>O<SUB>3</SUB>: CB catalyzed the degradation of PP, PE, and PS to selectively produce more aromatic compounds, which were subsequently dehydrogenated and reassembled into CNTs via the catalytic action of CB together with Ni particles. Moreover, the performance of the synthesized CNTs as the electrode of supercapacitor was investigated. The supercapacitor displayed a high specific capacitance as compared to supercapacitors using commercial CNTs and CB. This difference was attributed to the relatively larger specific surface areas of our synthetic CNTs and their more oxygen-containing groups.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/esthag/2014/esthag.2014.48.issue-7/es404646e/production/images/medium/es-2013-04646e_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/es404646e'>ACS Electronic Supporting Info</A></P>

Actinorugispora endophytica gen. nov., sp. nov., an actinomycete isolated from Daucus carota.

Liu, Min-Jiao,Zhu, Wen-Yong,Li, Jie,Zhao, Guo-Zhen,Xiong, Zhi,Park, Dong-Jin,Hozzein, Wael N,Kim, Chang-Jin,Li, Wen-Jun Society for General Microbiology 2015 International journal of systematic and evolutiona Vol.65 No.8

<P>An actinomycete strain, designated YIM 690008T, was isolated from Daucus carota collected from South Korea and its taxonomic position was investigated by using a polyphasic approach. The strain grew well on most media tested and no diffusible pigment was produced. The aerial mycelium formed wrinkled single spores and short spore chains, some of which were branched. The whole-cell hydrolysates contained meso-diaminopimelic acid, glucose, mannose, ribose, galactose and rhamnose. The predominant menaquinones were MK-10(H4), MK-10(H6), MK-10(H8) and MK-10(H2). The polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylinositol, phosphatidylinositol mannosides, some unknown phospholipids, glycolipids and polar lipids. The major fatty acids were i-C16?:?0, ai-C17?:?0 and C18?:?1ω9c. The DNA G+C content of the genomic DNA was 63.1?mol%. Phylogenetic analysis indicated that the isolate belongs to the family Nocardiopsaceae. However, based on phenotypic, chemotaxonomic and genotypic data, it was concluded that strain YIM 690008T represents a novel genus and novel species of the family Nocardiopsaceae, for which the name Actinorugispora endophytica gen. nov., sp. nov. (type strain YIM 690008T?=?DSM 46770T?=?JCM 30099T?=?KCTC 29480T) is proposed.</P>

Associations Between RASSF1A Promoter Methylation and NSCLC: A Meta-analysis of Published Data

Liu, Wen-Jian,Tan, Xiao-Hong,Guo, Bao-Ping,Ke, Qing,Sun, Jie,Cen, Hong Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.6

Background: RASSF1A has been reported to be a candidate tumor suppressor in non-small cell lung cancer (NSCLC). However, the association between RASSF1A promoter methylation and NSCLC remains unclear, particularly in regarding links to clinicopathologic features. Methods: Eligible studies were identified through searching PubMed, EMBASE, Cochrane Library and China National Knowledge Infrastructure (CNKI) databases. Studies were pooled and odds ratios (ORs) with corresponding confidence intervals (CIs) were calculated. Funnel plots were also performed to evaluate publication bias. Results: Nineteen studies involving 2,063 cases of NSCLC and 1,184 controls were included in this meta-analysis. A significant association was observed between RASSF1A methylation and NSCLC in the complete data set (OR = 19.42, 95% CI: 14.04-26.85, P < 0.001). Pooling the control tissue subgroups (heterogeneous/autologous) gave pooled ORs of 32.4 (95% CI, 12.4-84.5) and 17.7 (95% CI, 12.5-25.0) respectively. Racial subgroup (Caucasian/Asian) analysis gave pooled ORs of 26.6 (95% CI, 10.9-64.9) and 20.9 (95% CI, 14.4-30.4) respectively. The OR for RASSF1A methylation in poorly-differentiated vs. moderately/well-differentiated NSCLC tissues was 1.88 (95% CI, 1.32-2.68, P<0.001), whereas there were no significant differences in RASSF1A methylation in relation to gender, pathology, TNM stage and smoking behavior among NSCLC cases. Conclusion: This meta-analysis suggests a significant association between RASSF1A methylation and NSCLC, confirming the role of RASSF1A as a tumor suppressor gene. Large-scale and well-designed case-control studies are needed to validate the associations identified in the present meta-analysis.
