Objective:To study the characteristics of the clinical application of traditional herbal medicine in five countries and regions where traditional medicine(TM)is widely used:Japan;South Korea;China's Mainland;Hong Kong,China;Taiwan,China.And to analyze,from multiple angles,the variations in the methods of TM used in each countries and regions.Methods:Fifty commonly used traditional herbs(TOP50)from classical formulae were selected,and descriptive statistics,correlation analyses,and Friedman test were used to compare methods of clinical application and dosages in the countries and regions of interest based on a retrospective review of randomly-selected medical records.Results:There were significant differences in sequencing TOP50 among the five countries and regions(P<.01).The adherence to the classical formulae,from strong to weak was Japan;China's Mainland;Taiwan,China;Hong Kong,China;South Korea.There were also significant differences in TOP50 dosing regimens(P<.01).Overall dosages of TOP50 from high to low were:China's Mainland;Hong Kong,China;Taiwan,China;South Korea;Japan.Finally,there were significant differences in the dosage intervals(P<.01),with dosage intervals from maximum to minimum as follows:China's Mainland;Taiwan,China;Hong Kong,China;South Korea;Japan.Conclusions:The clinical dosages of traditional herbal medicine used in the China's Mainland are relatively large compared with those prescribed in the other four countries and regions,and the range of dosages in China's Mainland is more flexible.On the other hand,clinical dosages of TOP50 are the lowest in Japan,where the dosage range is also the narrowest,supporting the idea that Doctors of Kampo medicine are highly cautious and are likely to adhere strictly to classical formulae,while Hong Kong,China and Taiwan,China are in the middle.The dosage of TOP50 in South Korea is significantly lower than that used in the China's Mainland;Hong Kong,China and Taiwan,China where the adherence to the classical formulae was the lowest,albeit slightly higher than that in Japan.The methods of clinical application of traditional herbal medicine in the five countries and regions were affected by multiple factors,including history,geography,climate,and culture. 展开更多

Social network analysis(SNA) has been introduced to China's Mainland since the end of last century. It is often stated that SNA research has experienced rapid growth in China over these years, but few studies have been conducted to prove the statement. This paper aims at exploring the research status and development of SNA in China by a critical assessment of journal articles. Our findings show that SNA is an evolving and diversified research area which has rich themes and topics, and can be applied to those studies on different levels, context and disciplines, and attract researchers and scholars from various fields and domains. In addition, the information community(Library & Information Science and Information Systems) plays a leading role in the SNA related researches. The paper also points out the research on SNA in China has some limitations, so it proposes several implications for the future development of SNA research from perspectives of information science. 展开更多

At present, gravity field and steady-state ocean circulation explorer(GOCE) gravity data are always used to compute regional gravity anomaly and geoid height. In this study, the latest GOCE gravity field model data(from Oct. 2009 to Jul. 2010) are used to compute the gravity gradient of China's Mainland according to a rigorous recursion formula(in all the six directions). The results show that the numerical values of the gravity gradients are larger in the T rr direction than those in the other directions. They reflect the terrain characteristics in detail and correlate with the regional tectonics; however, in the T ql and T r l directions,the numerical values are relatively smaller and the gravity gradients in the T r l direction do not reflect the terrain characteristics in detail. 展开更多

Analysis of recent changes in the amount and nature of cultivated land and grain potential, and the impacts of these changes on grain security in China's Mainland provides vital information for revising and developing strategies regarding protection of cultivated land and national grain security. This study examined changes in the area of cultivated land and in grain potential in agro-ecological zones using the "change rate" method. Agro-ecological subzones were used as the basic units and agro-ecological zones as the research units. We then studied changes for all of China's Mainland using the "gravity centre model" and analyzed the structural change of cultivated lands in each agro-ecological zone to investigate the changes in detail. The results show that both cultivated land and grain potential in China's Mainland decreased from 1996 to 2007. The structural and quantitative changes in each zone have caused the shift of the gravity centres of cultivated land and grain potential in China's Mainland to the northeast. Unfortunately, it is unlikely that natural and economic resources can keep up with this change. Although a large gap remains between the grain potential and the actual grain yield, the rapid loss of grain potential and the direction of change pose great threats to grain security. To ensure comprehensive grain security in China, it is vital to rethink the regional patterns of grain production according to natural conditions without jeopardising cultivated land protection(quantitative and qualitative), and consider the direction of cultivated land use and reconstruction according to local natural conditions, water and soil resources, and the level of economic development, and then work steadily to improve the grain potential. 展开更多

Fog is an important indicator of weather. Long-term variations of fog and mist were studied byanalyzing the meteorological data from 743 surface weather stations in China's Mainland during 1951-2005.In climatology, there are more foggy days in the southeast than in the northwest China and more in thewinter half of the year than in the summer half. The decadal change of foggy days shows regional variation.Southwest China is the region with the most foggy days, and more than 20 foggy days occur in SichuanBasin in one year. Persistent heavy fog usually appears in winter and spring over the North China Plain andNortheast China Plain. Misty days are much more frequent in the provinces south of the Yangtze River thanin the regions north of it, and there is an obvious increase of misty days after the 1980s. Southwest China isthe area with the most number of misty days, and more than 100 misty days occur in Sichuan Basin in ayear. 展开更多

AIM:To investigate the current status of peritoneal carcinomatosis(PC) management,as well as the usage of cytoreductive surgery(CRS) and hyperthermic intraperitoneal chemotherapy(HIPEC) in China's Mainland.METHODS:A potentially curative therapeutic strategy for selecting patients with PC,known as "Techniques",consists of CRS in combination with HIPEC.A systemic search of published works and clinical trials was performed.Additional papers were retrieved by crosschecking references and obtaining information from Chinese oncologists and relevant conferences.One hundred and one papers and one registered clinical trial on HIPEC were included.RESULTS:A literature review identified 86 hospitals in 25 out of all 31 areas of China's Mainland that perform HIPEC.The earliest report included in our survey was published in 1993.Different approaches to HIPEC have been utilized,i.e.palliative,prophylactic,and possiblycurative treatment.Only one center has consistently performed HIPEC according to the "Sugarbaker Protocol",which involves evaluating the extent of PC with peritoneal cancer index and the results of CRS with the completeness of cytoreduction.Positive preliminary results were reported:7 of 21 patients with PC survived,free of tumors,during an 8-43-mo follow-up period.Hyperthermic strategies that include HIPEC have been practiced for a long time in China's Mainland,whereas the "Sugarbaker Protocol/Techniques" has been only rarely implemented in China.The Peritoneal Surface Oncology Group International hosts a biannual workshop with the intent to train more specialists in this field and provide support for the construction of quality treatment centers,especially in developing countries like China,whose population is huge and has a dramatically increased incidence of cancer.CONCLUSION:To popularize Sugarbaker Protocol/Techniques in China's Mainland in PC management arising from gastric cancer or colorectal cancer will be the responsibility of the upcoming Chinese Peritoneal Surface Oncology Group. 展开更多

MANDELBROT enunciated the uncertainty of the length of a coastline in his paper "How long is the coastline of Britain?" published in Science in 1967. The fractal concept was presented for the first time in that paper and has been applied to many fields ever since. Although fractal dimensions of lots of phenomena were calculated by the box-counting method,the quantitative influence of series of square grids on them is ignored. The issue is systematically discussed as a case study of the mountains of China′s Mainland in this paper. And some significant conclusions are drawn as follows: 1) Although the fractal character objectively exists in the mountains of China′s Mainland,and it does not vary with the changes of series of square grids,the fractal dimensions of the mountains of China′s Mainland are different with these changes. 2) The fractal dimensions of the mountains of China′s Mainland vary with the average lengths of sides of series of square grids. The fractal dimension of the mountains of China′s Mainland is the function of the average length of side of square grid. They conform to the formula D=f(r) (where D is the fractal dimension,and r is the average length of side of square grid). 3) Different dots of data collection can affect the fractal dimension of the mountains of China′s Mainland. 4) The same range of length of side of square grid and dots of data collection can ensure the comparison of fractal dimensions of the mountains of China′s Mainland. The research is helpful to get the more understanding of fractal and fractal dimension,and ensure that the fractal studies would be scientific. 展开更多
