HMGN5 is a typical member of the HMGN (high mobility group nucleosome-binding protein) family which may function as a nucleosomal binding and transcriptional activating protein. Overexpression of HMGN5 has been observed in several human tumors but its role in tumorigenesis has not been fully clarified. To investigate its significance for human lung cancer progression, we successfully constructed a shRNA expression lentiviral vector in which sense and antisense sequences targeting the human HMGN5 were linked with a 9-nucleotide loop. Inhibitory effects of siRNA on endogenous HMGN5 gene expression and protein synthesis were demonstrated via real-time RT-PCR and western blotting. We found HMGN5 silencing to significantly inhibit A549 and H1299 cell proliferation assessed by MTT, BrdU incorporation and colony formation assays. Furthermore, flow cytometry analysis showed that specific knockdown of HMGN5 slowed down the cell cycle at the G0/G1 phase and decreased the populations of A549 and H1299 cells at the S and G2/M phases. Taken together, these results suggest that HMGN5 is directly involved in regulation cell proliferation in A549 and H1299 cells by influencing signaling pathways involved in cell cycle progression. Thus, our finding suggests that targeting HMGN5 may be an effective strategy for human lung cancer treatment.

Ge-Fu(歌賦) means prose and poetry individually, and they both have a meaning of all the rhythmical poetrical compositions making it ease for people to remember the content. All the Ge-Fus used in oriental medicine are made in Yuan(元), Mine(明)and Qing(靑)dynasty, and they have been largely used in most of all the fields of medicine such as Ben-Cao(本草), Tang-Ye(湯液), Zhen-Jiu(鍼灸), Zhen-Duan(診斷). Zhen-Jiu-Ge-Fu(鍼灸歌賦) has about 90 poetries and 10 proses and they contain the names of meridian; courses of meridian streams; accurate positions of acupuncture points; functions; effects; meanings of the name of acupuncture points; usages and effects of special points; manipulations of reinforcing and reducing method; contraindications of acupuncturing; principles of selections and orders of acupuncture points in therapy; and eight diadgoses. Zhen-Jiu-Ge-Fu is subdivided into Jing-Xue(經穴歌), Zhi-Jiu-Ge(刺灸歌), Shu-Xue-Ge(輸穴歌), Zhi-Liao-Ge(治療歌). And In Zhi-Liao-Ge, the most brief and essential Ge-Fu-Si-Zong-Sue-Ge- contains theraputic designs using far apart acpuncture points from the right painful areas in the body. In this study, the author opinionated the Si-Zong-Sue-Ge can be the prototype of the distant needling; the research on this can open the importance of Ge-Fus. On conclusion, 1. "Upper and lower Abdomen - Zu-San-Li($S_{36}$) (肚腹三里留)" means when there are problems and disorders in upper and lower abdomen, distinctively, such as gastric pain, maldigestion, flatulence, abdominal pain, constipation, diarrhea, vomiting, menstrual disorer, knee pain and tonic functioning, 족삼리 can be a right choice for distant needling point for treating. 2.

The purpose of this study is how have the form and theory of the five element theory in the (黃帝內徑) by the investigation of the course of the course of the five element introduced the ancient oriental medicine from ancient oriental philosophy. The following results were obtained. 1. The five elements in (尙書) meaned the uses of water, fire, earth, wood, metal which were important in living. Because these had very important meaning in ancient political and economic society, emphasized to big law(洪範) 2. The five elements in (左傳) and (國語) mean the five uses too, and there are the phases of "five win metal"(火勝金) and "wather win fire"(水勝火), but these only meaned the physical interrelation. 3. In the five circulating factor theory made by Chu Yen(鄒衍) which have the attribute of the five elements, he more reasonably had argued human affairs like that a dynasty become different in step with the circulating five favors. There is the regular annual policy in the (呂氏春秋) which closely connected nature and human living, and attached the various colors, animals, visceras, flavors, sounds, the sexagenary cycle and so on to the five elements. 4. In the (春秋繁露) writed in fore-period of Han(漢) dynasty, the interactions of the five elements are concretely applicated to policy, Dong Jung Soe(童仲舒) had discrived the interactions of the five elements by Dong Lyu Sang Dong theory(同類相動說) and the misfortune theory(災異說), emphasized the sympathy of nature and human. Thought there is many content which are superstitious and contradictory, I concider which that affcted many effects in the formation of five element theory of oriental medicine. In the (淮南子) the order of matters were explained by the five element theory too, as the interrelations of the five elements were explained by the sexagenary ctcle, I assume that the bud of O-Un theory(五運理論). And there was not founded the fullscale intriduction of the five element theory in the Ma Wang Tye(馬王堆) excavated finds, the Mu Yyi medical writings formed the dynasty(武威漢代醫簡) and the documents about Pyun Jak(偏鵲) and Sun U Ie(淳于意). 5. The application of the five element theory in the (Whang Di Nei Qing) (黃帝內徑) is devided into the attachement to the five elements, the interelations of the five elments, and Un Gi theery(運氣論). In the attachment to the five elemeant theory, it made the attachment of the five viseras of (今文尙書) party a standard and attached the sections of a human body, the whole internal organs of sense, the five colors, the five flavors and the five sounds and so on to the five elements. It put to use by means of the apllivation of the interrelation of the five elements in the transferations of the diseases and the relative severeness of a disease in step with change of time and season. Un Gi theory(運氣論) which synthesized by the attachment to the five elements, the inter-relations of the five elements and the climate which observerd from ancient times systematically argued the effects of weather to human. 6. The application of the five elements theory in (黃帝內徑) have the significant what had get rid of irrational factors like that the emotion and action of human could to influense the weather, what had been formes more rational thingking by the obesrvation of human and nature. It is required more reserches about the possibility of the formation of the doctrinal faction bt the geographical effect of the Yon, Je(燕,薺) region, the application of the five element theory in other ancient medical books and the relationship of the five element theory and Yin Yang(陰陽)

National cancer incidence data were utilized to analyze trends in esophageal cancer incidence in China in order to provide basic information for making cancer control strategy. We retrieved and re-sorted valid esophageal cancer incidence data from National Central Cancer Registry Database over 20 years period from 1989 to 2008. Crude incidence and age-standardized incidence rates were calculated for analysis, with annual percent change estimated by Joinpoint software for long term trend analysis. The crude incidence rate of esophageal cancer was found to have remained relatively stable in both urban and rural areas over the 20 year period. Age standardized incidence rate (ASR) in cancer registration areas decreased from 39.5/100,000 in 1989 to 23.0/100,000 in 2008 in all areas (AAPC=-3.3%, 95% CI:-2.8~-3.7). The trend was no change in urban areas and 2.1% average annual decrease observed in rural aras. Before the year of 2000, esophageal cancer incidence rates significant decreased with 2.8% annually and then the rates kept stable. Over 20 years from 1989 to 2008, esophageal cancer age standardized incidence rate in cancer registration areas decreased with time. However, esophageal cancer is still a big issue and efforts for control should be continuously enhanced. Cancer registration is playing an important role in cancer control with the number of registries increasing and data quality improving in China.

The aim of this study was to investigate the effects of olanzapine on growth inhibition as well as autophagy in glioma cells in vitro and in vivo. The proliferation of both LN229 and T98 glioma cells, measured by MTT assay, was suppressed in a concentration-dependent and time-dependent manner. Moreover, apoptosis of both cells was significantly increased with the treatment of olanzapine as evidenced by increased Bcl-2 expression, Hoechst 33258 staining and annexinV-FITC/PI staining. Olanzapine treatment also enhanced activation of autophagy with increased expression of LC3-II, expression of protein p62, a substrate of autophagy, being decreased. The growth inhibition by olanzapine in both glioma cell lines could be blocked by co-treatment with 3-MA, an autophagy inhibitor. Furthermore, olanzapine effectively blocked the growth of subcutaneous xenografts of LN229 glioma cells in vivo. The increased level of protein LC3-II and decreased level of p62 followed by a decreased level of Bcl-2, suggesting that autophagy may contribute to apoptosis. In addition, reduced proliferation of glioma cells was shown by a decrease of Ki-67 staining and increased caspase-3 staining indicative of apoptosis in mouse xenografts. These results indicated that olanzapine inhibited the growth of glioma cells accompanied by induction of autophagy and apoptosis both in vitro and in vivo. Olanzapine-induced autophagy plays a tumor-suppressing role in glioma cells.

With the explosive growth of information in our real life, information filtering is quickly becoming a popular technique for reducing information overload. Information filtering technique is divided into two categories: content-based filtering and collaborative filtering (or social filtering). Content-based filtering selects the information based on contents; while collaborative filtering combines the opinions of other persons to make a prediction for the target user. In this paper, we describe a new filtering approach that seamlessly combines content-based filtering and collaborative filtering to take advantages from both of them, where a technique using user profiles efficiently on the collaborative filtering framework is introduced to predict a user's preference. The proposed approach is experimentally evaluated and compared to conventional filtering. Our experiments showed that the proposed approach not only achieved significant improvement in prediction quality, but also dealt with new users well.

The results of the study can be summarized as follows. The Shu-mu Da-wen was selected and compiled by Zhang Zhi Dong at the end of Qing Dynasty as a reading list for students preparing for the state examination and for the purpose of choosing the best from several versions. Whether it was compiled and edited by Zhang was in dispute. But it is almost certain that Zhang was the main editor because Shu-mu Da-wen showed his political, educational and scientific thoughts and knowledge distinctively. The followings are characteristics of Shu-mu Da-wen being compared with Si-ku Quan-shu Zong-mu Ti-yao. 1. In Jing-bu, the Confucian classics are divided into Zheng-jing Zheng-zhu and 'Lie-chao Jing-zhu Jing-shuo Jing-ben kao-zheng. Zheng-shi lei is divided into Zheng-shi fen he ke ben and Zheng-shi zhu bu biao pu kao-zheng. It is the special sorting method to include Du-ben lei in Jing-bu and Chu xue du-ben in Bie-lu in order to provide first learners for reading order. 2. Shi-bu included Gu-shi newly and Di-li lei is divided into Gu Di-li and Jin di-li in Shi-bu. Tian-wen Suan-fa lei is divided into Zhong-fa and Xi-fa in Zi-bu. Zhang distinguished between old books and contemporary ones to find out the origin and include newly published books in the East and the West. 3. Zhou-Qin zhu-zi is newly added to Zi-pu. In Ji-pu, Bie-ji and Zong-ji are categorized according to their style and period respectively. This show the new sorting method which added classifying system concerning academic development. It is the prominent feature in the compiling system to make Bie-lu and Cong-shu respective chapters. With those characteristics the Shu-mu Da-wen had been edited and published several times. It had a wide effect not only on compiling methods of cataloging afterwards and but also on classification systems before decimal classification was introduced in China.

Nasopharyngeal carcinoma (NPC) is a disease with distinct ethnic and geographic distribution. The incidence of NPC in Chinese residing in Asia has declined over the last few decades, but NPC mortality trends in the entire Chinese population over time have not been systematically evaluated. In this study, we examined NPC mortality at the national level in China between 1973-2005. Mortality rates were derived from the databases of national retrospective surveys on cancer mortality conducted in the periods of 1973-1975, 1990-1992, and 2004-2005, respectively. NPC was classified according to the International classification of diseases. Age-adjusted mortality rates were calculated by direct standardization according to the world standard population. Trends in rates were evaluated by age, gender, geographic areas, and socioeconomic status. From 1973 to 2005, there was a general trend of decrease in NPC mortality in China, with higher rates in the south on a downward trend in the north. The age-standardized NPC mortality rates were 2.60 per 100,000 in 1973-1975, 1.94 per 100,000 in 1990-1992, and 1.30 per 100,000 in 2004-2005, respectively. The trend was similar in both men and women, in both urban and rural areas, but the declining rates in females were more remarkable than in males. The mortality rates were higher for the age groups above 50 years than those less than 50 years of age, both showing downward trend over 30-year period. In summary, the overall NPC mortality has consistently decreased in China over the past three decades, particularly in women and in old adults.

Objective: To estimate the incidence and mortality rates for pancreatic cancer in China. Methods: After checking and reviewing the cancer registry data in 2009 from 72 cancer registry centers, we divided cancer registry areas into urban and rural areas. Incidence/mortality rates, age-specific incidence/mortality rates, age-standardized incidence/mortality rates, proportions, and cumulative incidence/mortality rates for pancreatic cancer were calculated. Results: The total number of newly diagnosed pancreatic cancer cases and deaths in 2009 were 6,220 and 5,650, respectively. The crude incidence rate in all cancer registry areas was 7.28/100,000 (males 8.24, females 6.29). The age-standardized incidence rate by Chinese standard population (ASR) was 3.35/100,000, with ranking at 7th among all cancers. Pancreatic cancer incidence rate was 8.19/100,000 in urban areas whereas it was 5.41/100 000 in rural areas. Cancer mortality rate in all cancer registry areas was 6.61/100,000 (males 7.45; females 5.75), with ranking at 6th among all cancers, and 7.42/100 000 in urban but 4.94/100000 in rural areas. Conclusions: Pancreatic cancer incidence and mortality rates have shown a gradual increase in China. Owing to the difficulty of early diagnosis, identification of high-risk population and modification of risk factors are important to reduce the burden of pancreatic cancer.
