Methods: Using the information of incidence, death registration information database and population data of malignant tumors in 2010 in the residents of Hai’an county, the incidence, mortality, accumulation incidence rates, and truncated incidence rate of malignant tumors were statistically analyzed. Results: The crude incidence, China standardized and world standardized incidence rates of malignant tumors in 2010 in Hai’an county were 281.53 per 100000 persons, 174.96 per 100 000 persons, and 175.14 per 100000 persons, respectively. The cumulative incidence rate from aged 0 to 64 years, the cumulative incidence rate from aged 0 to 74 years and the truncated incidence rate from aged 35 to 64 years were 6.85%, 15.39%, and 193.26 per 100000 persons, respectively. The rough mortality rate, China standardized and world standardized incidence rates were 234.11 per 100000 persons, 145.30 per 100000 persons, and 144.77 per 100000 persons, respectively. The top five cancers in the spectrum of cancer incidence were respectively esophageal cancer, lung cancer, stomach cancer, liver cancer, and colorectal cancer. The top four cancers in the spectrum of cancer death were consistent with the spectrum of cancer incidence. The 5th cancer in the spectrum of cancer death was pancreatic cancer. The incidence and mortality of various age groups were at a low level before 35-year-old age group. The incidence of female was slightly higher than that of male. But the incidence and mortality from the age group of 50 showed "suddenly" upward trend with age. The incidence and mortality of male were significantly higher than those of female. The ratios of male to female of incidence and mortality were 1.52:1 and 1.67:1, respectively. Conclusion: Residents over the age of 50, especially males, are high-risk groups who are exposed to certain risk factors. They should be the key objects of prevention and treatment of malignant tumors.展开更多

There is a big gap between their social security needs and the system and policies. It is an important task for the rural disabled to help the disabled to get rid of poverty and to solve their food and clothing. It is an important task to build a new socialist countryside and build a well-offsociety in an all-round way. It needs to be more effectively solved in the system construction of social security and social services. This paper, taking the rural of Shuyang County of Jiangsu Province as the research object, analyzes the situation and demand of the social security of the disabled in China, points out its existing problems and outs forward some countermeasures and suggestions.展开更多

The SJP district is a well-known tungsten producer in South China where distributes several ore concentrated areas such as the "Chongyi-Dayu-Shangyou", "Yudu" and "Longnan-Quanan-Dingnan"areas, with many large and super large tungsten deposits including the famous Xihuashan, Piaotang, Pangushan and Dajishan deposits. In recent years, major prospecting breakthrough for W-polymetallic resources has been made in the NJSAP district.Several large and super large W-Cu(Mo) deposits, such as the Dahutang, Zhuxi, Dongyuan and Baizhangyan deposits, are discovered. These deposits are all genetically associated with the Yanshanian(Mesozoic) granitic magmatism. In this study, a systematic comparison of the temporal and spatial distribution, petrology, geochronology, and geochemical characteristics of the tungsten-bearing granites between the SJP and NJSAP districts has been made, with an aim to improving the understanding of the petrogenesis of the granites and associated metal enrichment mechanisms in the two tungsten ore districts in South China. The following conclusions can be drawn:(1) The ages of the tungsten-bearing granites and associated mineralization are different in the two districts, in the SJP district the ages are mainly concentrated in 165–150 Ma, whereas in the NJSAP district it displays two age periods, one is 150–140 Ma(Late Jurassic-Early Cretaceous), and the other is 135–120 Ma(Early Cretaceous).(2) The tungsten-bearing granites from both the NJSAP and SJP districts are highly fractionated granitic rocks, but the SJP granites have experienced higher degree of fractional crystallization and more extensive fluid metasomatism than the NJSAP granites.(3) The petrogeneses of the tungsten-bearing granites from the two districts are different, those from the NJSAP district originated from partial melting of less mature sandstone-mudstone intercalated with meta-volcanic rocks of the Neoproterozoic Shuangqiaoshan Group which are both W and Cu enriched, in contrast those from the SJP district were likely derived from the highly mature,clay-rich mudstones of the Mesoproterozoic age which are only W enriched. In summary, the different source rocks with different metal enrichment features and different magmatic evolution and fractional degrees for the granites in the two districts might be the key factors that controlled the different matallogenic characteristics of tungsten ore deposits in the two districts in South China.展开更多

The aim wasto observe the polar plumes (PPs) with high spatial and temporal resolutions in white-light. With the observational data, weinvestigate the properties and evolution of the PPs and compare them with those of the low-latitude plumes (LPs). We find thatboth the PPs and the LPs have comparable lengths and widths, and the mean length and width are 300 Mm and 16 Mm, re-spectively. The average inclination angle (13 degree) of the PPs is smaller than that (32 degree) of the LPs. Generally, theplumes which are closer to the coronal hole center are more vertical. We trace the PPs and the LPs in the sequence of imagesand find that none of them disappears and no new one is created. Additionally, neither plasma outflow nor transverse oscilla-tion is observed. These imply that the evolution process of plumes is much longer than the timescale of eclipse.展开更多
