楊釗(Yang Zhao) 중국어문학연구회 2016 중국어문학논집 Vol.0 No.98

Yang Shen, in the introduction to “Arts and Literatures History of the Whole Shu nation”, provided that the cultural background of editting this book was to “carry forward the fragrance of the Si Zi, and write the Su nation’s history”. Thus the selected works in this book were not only the literatural ones but also those that reflected the Bashu’s history and academic thoughts. Meanwhile, he had self-consciously assumed the responsibilities of the inheritance of the rural culture and encouraging the backwards through editting the book. Yang Shen and his son had carried forward the local culture through the following three aspects, that is, to devote much attention to the nation’ history, to praise the local loyal bachelors and to place emphasize on the moral education.Besides, Yang Shen and his son had taken great pains to discuss these issues and carry out the social pracitice.

Purpose Mixed-lineage leukemia protein 4 (MLL4/KMT2D) is a histone methyltransferase, and its mutation has been reported to be associated with a poor prognosis in many cancers, including lung cancer. We investigated the function of MLL4 in lung carcinogenesis. Materials and Methods RNA sequencing (RNA-seq) in A549 cells transfected with control siRNA or MLL4 siRNA was performed. Also, we used EdU incorporation assay, colony formation assays, growth curve analysis, transwell invasion assays, immunohistochemical staining, and in vivo bioluminescence assay to investigate the function of MLL4 in lung carcinogenesis. Results We found that MLL4 expression was downregulated in non–small cell lung cancer (NSCLC) tissues compared to adjacent normal tissues and tended to decrease with disease stage progression. We analyzed the transcriptomes in control and MLL4- deficient cells using high-throughput RNA deep sequencing (RNA-seq) and identified a cohort of target genes, such as SOX2, ATF1, FOXP4, PIK3IP1, SIRT4, TENT5B, and LFNG, some of which are related to proliferation and metastasis. Our results showed that low expression of MLL4 promotes NSCLC cell proliferation and metastasis and is required for the maintenance of NSCLC stem cell properties. Conclusion Our findings identify an important role of MLL4 in lung carcinogenesis through transcriptional regulation of PIK3IP1, affecting the PI3K/AKT/SOX2 axis, and suggest that MLL4 could be a potential prognostic indicator and target for NSCLC therapy.

論錢穆對漢代『春秋』學的硏究

楊兆貴 ( Yang¸ Zhao Gui ),趙殷尙 ( Cho¸ Eun Sang ) 한국중국학회 2021 중국학보 Vol.97 No.-

錢穆對秦漢史、漢代經學研究飮譽學林, 影響很大。他這兩方面的論著大多已逾半世紀, 在出土文獻日益增多、研究方法多元化等學風下, 他的論著有哪些價值?對當代相關研究有什麼影響?筆者結合他這兩方面的研究, 聚焦他的漢代『春秋』學, 以見他治學、見解之一斑。 要探討他對漢代『春秋』學的看法, 則先簡介他對『春秋』及三傳的看法。他與傳統主張孔子作『春秋』的看法相同, 並從史學肯定『春秋』、『左傳』的史學價值。他認為漢代經學今古文之別是王官學與百家言之殊, 而非文字古今之異。這是他論漢代經今古文最具特色的部分。他撰『孔子與春秋』一文, 著重闡釋『公羊』學的精神, 強調孔子『春秋』以百家言而成為新的王官學。他在不同時期對『公羊』學與董仲舒的評價不同。他認為漢儒多通古今, 因此治『春秋』者多能兼採三傳或兩傳之義、說。他又指出, 『春秋』學與漢代思想尤其是災異說、禪讓說、禮制說有密切的關係。 Prof. Qian Mu has a great influence on the honorary scholars of Qin and Han history and Han dynasty studies. Most of his works in these two areas have been over half a century. With the increasing number of unearthed documents and diversified research methods, what is the value of his works? And what is the impact on contemporary related research? This essay combines his research in these two areas and focuses on his study of Chun Qiu in the Han Dynasty, so as to see his academic research methods and insights. To explore his views on the study of Chun Qiu in the Han Dynasty, the first part of the essay introduces his views on Chun Qiu and the three ‘Zhuan’. He is the same as the traditional view that Confucius wrote Chun Qiu, and affirmed the historical value of Chun Qiu and Zuo Zhuan from his historiography. He believes that the difference between modern and ancient literatures in Han dynasty is the difference between Ancient Official Document and Philosophers, rather than the difference between ancient and modern writing. He wrote the article Confucius and Chun Qiu, focusing on explaining the spirit of school of Gong Yang, emphasizing that Confucius' Chun Qiu became a new official ideology with the philosophical thought in Han China. He had different evaluations of Gong Yang and Dong Zhongshu in different periods. He believes that the Han scholars are mostly integrated with the ancient and modern literatures, so most of them who studied Chun Qiu can adopt the meaning and theories of the three or two ‘Zhuan’ at the same time. He also pointed out that the study of Chun Qiu has a close relationship with the thoughts of the Han Dynasty, especially the theory of catastrophe, concession, and etiquette.

Spatial–Temporal Clustering and Optimization of Aircraft Descent and Approach Trajectories

Zhao Yang,Rong Tang,Yixin Chen,Bing Wang 한국항공우주학회 2021 International Journal of Aeronautical and Space Sc Vol.22 No.6

This study presents a procedure for the spatial–temporal clustering and optimization of aircraft descent and approach trajectories. First, the spatial–temporal similarity between two trajectories is defined. Clustering analysis are conducted to identify the prevailing trajectories. The clustering centers obtained based on spatial–temporal distance are compared with those obtained based on the traditional Euclidean distance. Second, a multi-objective optimization model is established to minimize fuel consumption, aircraft emission and noise impact considering flight constraints. The Pareto solution that has the highest similarity with the prevailing trajectories is selected as the final optimized trajectory. The performance indicators of the optimized trajectory are compared with the average values of historic trajectories. It is found that travel time, fuel consumption and noise impact for the optimized trajectory are reduced by 5.34%, 0.96% and 11.86%, respectively. The percentages are 0.96%, 1.32%, 9.18%, 3.54% and 4.00% for CO2, SOx, NOx, CO and HC, respectively. Also, the performance indicators for the two clustering centers based on spatial–temporal distance are generally closer to average performance of original trajectories, as well as those of the optimized trajectories, as compared with the two clustering centers based on Euclidean distance. The spatial–temporal clustering methods may help to discover the valuable information that lies in those indicators associated with features reflected in time dimension.

Production of Transgenic Pigs with an Introduced Missense Mutation of the Bone Morphogenetic Protein Receptor Type IB Gene Related to Prolificacy

Zhao, Xueyan,Yang, Qiang,Zhao, Kewei,Jiang, Chao,Ren, Dongren,Xu, Pan,He, Xiaofang,Liao, Rongrong,Jiang, Kai,Ma, Junwu,Xiao, Shijun,Ren, Jun,Xing, Yuyun Asian Australasian Association of Animal Productio 2016 Animal Bioscience Vol.29 No.7

In the last few decades, transgenic animal technology has witnessed an increasingly wide application in animal breeding. Reproductive traits are economically important to the pig industry. It has been shown that the bone morphogenetic protein receptor type IB (BMPR1B) A746G polymorphism is responsible for the fertility in sheep. However, this causal mutation exits exclusively in sheep and goat. In this study, we attempted to create transgenic pigs by introducing this mutation with the aim to improve reproductive traits in pigs. We successfully constructed a vector containing porcine BMPR1B coding sequence (CDS) with the mutant G allele of A746G mutation. In total, we obtained 24 cloned male piglets using handmade cloning (HMC) technique, and 12 individuals survived till maturation. A set of polymerase chain reactions indicated that 11 of 12 matured boars were transgene-positive individuals, and that the transgenic vector was most likely disrupted during cloning. Of 11 positive pigs, one (No. 11) lost a part of the terminator region but had the intact promoter and the CDS regions. cDNA sequencing showed that the introduced allele (746G) was expressed in multiple tissues of transgene-positive offspring of No.11. Western blot analysis revealed that BMPR1B protein expression in multiple tissues of transgene-positive $F_1$ piglets was 0.5 to 2-fold higher than that in the transgene-negative siblings. The No. 11 boar showed normal litter size performance as normal pigs from the same breed. Transgene-positive $F_1$ boars produced by No. 11 had higher semen volume, sperm concentration and total sperm per ejaculate than the negative siblings, although the differences did not reached statistical significance. Transgene-positive $F_1$ sows had similar litter size performance to the negative siblings, and more data are needed to adequately assess the litter size performance. In conclusion, we obtained 24 cloned transgenic pigs with the modified porcine BMPR1B CDS using HMC. cDNA sequencing and western blot indicated that the exogenous BMPR1B CDS was successfully expressed in host pigs. The transgenic pigs showed normal litter size performance. However, no significant differences in litter size were found between transgene-positive and negative sows. Our study provides new insight into producing cloned transgenic livestock related to reproductive traits.

Correction: Robust MAVE for single‑index varying‑coefficient models

Zhao Yang,Yue Lili,Li Gaorong 한국통계학회 2022 Journal of the Korean Statistical Society Vol.51 No.4

In this paper, a robust, efficient and easily implemented estimation procedure for single-index varying-coefficient models is proposed by combining minimum average variance estimation (MAVE) with exponential squared loss. The merit of the proposed method is robust against outliers or heavy-tailed error distributions while asymptotically efficient as the original MAVE under the normal error case. A practical minorization–maximization algorithm is proposed for implementation. Under some regularity conditions, asymptotic distributions of the resulting estimators are derived. Simulation studies and a real data example are conducted to examine the finite sample performance of the proposed method. Both theoretical and empirical findings confirm that our proposed method works very well.

Korean Red Ginseng attenuates anxiety-like behavior during ethanol withdrawal in rats

Zhao, ZhengLin,Kim, Young Woo,Wu, YiYan,Zhang, Jie,Lee, Ju-Hee,Li, XiaoHua,Cho, Il Je,Park, Sang Mi,Jung, Dae Hwa,Yang, Chae Ha,Kim, Sang Chan,Zhao, RongJie The Korean Society of Ginseng 2014 Journal of Ginseng Research Vol.38 No.4

Background: Korean Red Ginseng (KRG) is known to have antianxiety properties. This study was conducted to investigate the anxiolytic effects of KRG extract (KRGE) during ethanol withdrawal (EW) and the involvement of the mesoamygdaloid dopamine (DA) system in it. Methods: Rats were treated with 3 g/kg/d of ethanol for 28 d, and subjected to 3 d of withdrawal. During EW, KRGE (20 mg/kg/d or 60 mg/kg/d, p.o.) was given to rats once/d for 3 d. Thirty min after the final dose of KRGE, anxiety-like behavior was evaluated in an elevated plus maze (EPM), and plasma corticosterone (CORT) levels were determined by a radioimmunoassay (RIA). In addition, concentrations of DA and 3,4-dihydroxyphenylacetic acid (DOPAC) in the central nucleus of the amygdala (CeA) were also measured by high performance liquid chromatography (HPLC). Results: The EPM test and RIA revealed KRGE inhibited anxiety-like behavior and the over secretion of plasma CORT during EW. Furthermore, the behavioral effect was blocked by a selective DA D2 receptor (D2R) antagonist (eticlopride) but not by a selective DA D1 receptor (D1R) antagonist (SCH23390). HPLC analyses showed KRGE reversed EW-induced decreases of DA and DOPAC in a dose-dependent way. Additionally, Western blotting and real-time polymerase chain reaction (PCR) assays showed that KRGE prevented the EW-induced reductions in tyrosine hydroxylase (TH) protein expression in the CeA and TH mRNA expression in the ventral tegmental area (VTA). Conclusion: These results suggest that KRGE has anxiolytic effects during EW by improving the mesoamygdaloid DA system.
