Zhan Long Shen,송교영,Ying Jiang Ye,Qi Wei Xie,Bin Liang,Kewei Jiang,박조현,Shan Wang 대한위암학회 2015 Journal of gastric cancer Vol.15 No.1
Purpose: To compare the clinicopathological data and long-term survival of gastric cancer patients in China and Korea. Materials and Methods: Patients who had undergone gastrectomy for gastric cancer between 1998 and 2009 in 2 high-volume institutions in both China (n=1,637) and Korea (n=2,231) were retrospectively evaluated. Clinicopathological variables, overall survival (OS), progression-free survival (PFS), and surgery-related complications were assessed for all patients and compared between the 2 institutions. Results: Chinese patients included in the study were significantly older and had a significantly lower body mass index (BMI) than the Korean patients. Esophagogastric junction tumors were more frequent in Chinese patients. However, the number of patients with stage I gastric cancer, the number of harvested lymph nodes, and the number of total gastrectomies were significantly higher in the Korean population. Korean patients also presented with fewer undifferentiated tumors than Chinese patients. Furthermore, Korean patients had prolonged OS and PFS for stage III cancers only. BMI, tumor-node-metastasis (TNM) stage, tumor invasion, number of positive lymph nodes, and distant metastases were all independent factors affecting OS and PFS. Conclusions: Although China and Korea are neighboring Asian countries, the clinicopathological characteristics of Chinese patients are significantly different from those of Korean patients. Korean gastric cancer patients had longer OS and PFS than Chinese patients. Influencing factors included TNM stage, tumor invasion, and lymph node metastasis.

Night shift workers with disordered rhythmic mechanical loading are more prone to intervertebral disc degeneration (IDD). Our results showed that circadian rhythm (CR) was dampened in degenerated and aged NP cells. Long-term environmental CR disruption promoted IDD in rats. Excessive mechanical strain disrupted the CR and inhibited the expression of core clock proteins. The inhibitory effect of mechanical loading on the expression of extracellular matrix genes could be reversed by BMAL1 overexpression in NP cells. The Rho/ROCK pathway was demonstrated to mediate the effect of mechanical stimulation on CR. Prolonged mechanical loading for 12 months affected intrinsic CR genes and induced IDD in a model of upright posture in a normal environment. Unexpectedly, mechanical loading further accelerated the IDD in an Light-Dark (LD) cycle-disrupted environment. These results indicated that intrinsic CR disruption might be a mechanism involved in overloading-induced IDD and a potential drug target for night shift workers.

Pluripotent stem cells only exist in a narrow window during early embryonic development, whereas multipotent stem cells are abundant throughout embryonic development and are retained in various adult tissues and organs. While pluripotent stem cell lines have been established from several species, including mouse, rat, and human, it is still challenging to establish stable multipotent stem cell lines from embryonic or adult tissues. Based on current knowledge, we anticipate that by manipulating extrinsic and intrinsic signaling pathways, most if not all types of stem cells can be maintained in a long-term culture. In this article, we summarize current culture conditions established for the long-term maintenance of authentic pluripotent and multipotent stem cells and the signaling pathways involved. We also discuss the general principles of stem cell maintenance and propose several strategies on the establishment of novel stem cell lines through manipulation of signaling pathways.

20世纪90年代以来的全球化进程, 对中国的岭南文化发展影响巨大。资本的扩张与全球经济一体化必然形成文化上的诉求, 使岭南文化原有的多样性逐渐减弱, 西方文化的同质化特征日趋明显。但因全球化并非均质的、同一的进程, 而是呈现出相互交错的、互不平衡的态势, 使得岭南文化依然均有保持自身特点的空间。文化格局中的中心与边缘位置并非永恒不变, 边缘文化具有自身独特的活力, 可以成为特定地域中人们的精神、情感寄托。文化具有物质、制度和精神三个不同层次, 岭南文化面对全球化的强力冲击, 一方面应该以发展经济、科技为原则 另一方面应坚持民族的、地域的文化特性, 取长补短, 在融合中发展。 Since 1990s the process of globalization has had a great influence on the development of Lingnan Culture. The expansion of capital and the integration of the global economy will inevitably form cultural appeals, which will weaken the original diversity of the Lingnan Culture and make the homogenization characteristics of western culture more and more obvious. However, because globalization is not a homogeneous and identical process, it presents a staggered and unbalanced situation, which makes the Lingnan Culture still maintain its own characteristics. The position of the center and the edge in the cultural pattern is not eternal. The edge culture has its own unique vitality and can become the spiritual and emotional sustenance of people in specific areas. Culture has three different levels of material, system and spirit. On the one hand, the Lingnan Culture should face the strong impact of globalization. On the one hand, it should be based on the principles of developing economy and science and technology. On the other hand, it should adhere to the cultural characteristics of the nation and region, learn from each other's strengths, and develop in the process of integration.

Jin Hui-long,Zhang Miao,Qi Shu-li 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.5
The optimal discrete signal are widely used in spread spectrum communication systems, sonar, navigation, code division multiple access systems and other fields. The perfect sequence pair is an extension of the single best signal, so its application is more widely. This paper puts forward new methods of constructing the binary sequence pair of three values and quaternion sequence pair of three values according to the problem of constructing the sequence pairs of three values. This method is that it uses N long cyclotomic pseudo-random sequence and its shift sequences pair to do series connection to constitute a 4 N long binary sequence pair of three values. New sequence pairs of three values is obtained by this method proved to have good balance. The application steps of this method are given and shall be verified by some examples.

Octacosanol, which has prominent physiological activities and functions, has been recognized as a potential growth promoter in animals. A total of 392 1-d-old male Arbor Acres broiler chicks with similar body weight were randomly distributed into four dietary groups of seven replicates with 14 birds each supplemented with 0, 12, 24, or 36 mg octacosanol (extracted from rice bran, purity >92%)/kg feed. The feeding trial lasted for six weeks and was divided into the starter (day 1 to 21) and the grower (day 22 to 42) phases. The results showed that the feed conversion ratio (FCR) was significantly improved in broilers fed a diet containing 24 mg/kg octacosanol compared with those fed the control diet in the overall phase (day 1 to 42, p = 0.042). The average daily gain and FCR both showed linear effects in response to dietary supplementation of octacosanol during the overall phase (p = 0.031 and 0.018, respectively). Broilers fed with 24 or 36 mg/kg octacosanol diet showed a higher eviscerated yield, which increased by 5.88% and 4.26% respectively, than those fed the control diet (p = 0.030). The breast muscle yield of broilers fed with 24 mg/kg octacosanol diet increased significantly by 12.15% compared with those fed the control diet (p = 0.047). Eviscerated and breast muscle yield increased linearly with the increase in dietary octacosanol supplementation (p = 0.013 and 0.021, respectively). Broilers fed with 24 or 36 mg/kg octacosanol diet had a greater (p = 0.021) $pH_{45min}$ value in the breast muscle, which was maintained linearly in response to dietary octacosanol supplementation (p = 0.003). There was a significant decrease (p = 0.007) in drip loss value between the octacosanol-added and the control groups. The drip loss showed linear (p = 0.004) and quadratic (p = 0.041) responses with dietary supplementation of octacosanol. These studies indicate that octacosanol is a potentially effective and safe feed additive which may improve feed efficiency and meat quality, and increase eviscerated and breast muscle yield, in broiler chicks. Dietary supplementation of octacosanol at 24 mg/kg diet is regarded as the recommended dosage in the broilers' diet.

A Noninjection Reaction Route to CuInSe2 Nanocrystals with Triethanolamine as the Complexing Agent
Qi-Yi Zhang,Wen-Long Liu,Meng-Qiang Wu,Ru-Chao Zhou,Li-Dan Yan,Shu-Ren Zhang 대한화학회 2011 Bulletin of the Korean Chemical Society Vol.32 No.12
The chalcopyrite-type CuInSe_2 is a remarkable material for thin film solar cells owing to its electronic structure and optical response. Single-phase sphere-like CuInSe_2 nanocrystallite particles were prepared by a facile noninjection method with triethanolamine as the complexing agent and the solvent simultaneously. The period of the reaction was the key to form single-phase CuInSe_2 nanocrystals at 240 ^oC. TEM, XRD, XPS, EDX investigations were performed to characterize the morphology and the detailed structure of as-synthesized CuInSe_2 nanocrystals. All of the analysis results proved that the synthesized nanocrystals were pure phase and close to the stoichiometric ratio rather than a simple mixture. The band gap of the obtained CuInSe_2nanocrystals was 1.03 ± 0.03 eV.
