Analysis of the Bacterial Communities in Lime Concretion Black Soil upon the Incorporation of Crop Residues  [PDF]
Shao-Qiang Tao, Qiang Xia, Lin Zhu, Jing-jing Chen, Ya- Nan Wang, Bing Qin
Open Journal of Soil Science (OJSS) , 2012, DOI: 10.4236/ojss.2012.23037
Abstract: To analyze the bacterial communities in lime concretion black soil upon the incorporation of crop residues for two years in wheat-maize system, total DNA was directly extracted and PCR-amplified with the F357GC and R518 primers targeting the 16S rRNA genes of V3 region. The amplified fragments were analyzed by perpendicular DGGE. Analyzing of species richness index S and Shannon diversity index H revealed that there was a high diversity of soil bacterial community compositions among all treatments after incorporation of crop residues and fertilizing under field conditions. Eleven DGGE bands recovered were re-amplified, sequenced. Phylogenetic analysis of the representative DGGE fingerprints identified four groups of the prokaryotic communities in the soil by returning wheat residues and fertilizing under field conditions. The bacterial communities belonged to gamma proteobacterium, Cupriavidus sp, halophilic eubacterium, Acidobacterium sp, Sorangium sp, delta proteobacterium, Streptococcus sp and Streptococcus agalactiae were main bacterial communities. Principal Component Analysis (PCA) showed that there were the differences in DNA profiles among the six treatments. It showed that wheat residue returning, maize residue returning and fertilizing all can improve bacterial diversity in varying degrees. As far as improvement of bacterial diversity was concerned, wheat residue returning was higher than fertilizing, and fertilizing higher than maize residue returning.

World Journal of Gastroenterology , 2012, DOI: 10.3748/wjg.v18.i11.1262
Abstract: AIM: To investigate the incidence and mortality of gastric cancer (GC) in Zhuanghe region, northeast China and the influencing factors for their changing trends. METHODS: All new cancer cases and deaths registered from 2005 to 2010 in Zhuanghe County were reviewed. The annual GC cases, constituent ratio, crude rates, age-standardized rates, their sex and age distribution and temporal trends were assessed. The method of annual percentage change (APC) was used to estimate the trends of GC. RESULTS: Altogether 2634 new cases of GC and 1722 related deaths were registered, which accounted for 21.04% and 19.13% of all cancer-related incidence and deaths, respectively. The age-standardized incidence rate steadily decreased from 57.48 in 2005 to 44.53 in 2010 per 105 males, and from 18.13 to 14.70 per 105 females, resulting in a APC of -5.81% for males and -2.89% for females over the entire period. The magnitude of APC in GC mortality amounted to -11.09% and -15.23%, respectively, as the age-standardized mortality rate steadily decreased from 42.08 in 2005 to 23.71 in 2010 per 105 males, and from 23.86 to 10.78 per 105 females. Females had a significantly lower incidence (a male/female ratio 2.80, P < 0.001) and mortality (a male/female ratio 2.30, P < 0.001). In both genders, the peak incidence and mortality occurred in the 80-84 years age group. The age-standardized mortality/incidence ratio also decreased from the peak of 0.73 in 2005 to 0.53 in 2010 for males, and from 1.32 to 0.73 for females. CONCLUSION: Encouraging declines of incidence and mortality of GC were observed in Zhuanghe region between 2005 and 2010, possibly due to the economic development and efficient GC control strategies.

Kinetic property analysis of emergent behaviors in Swarm model

Wu Yu,Yang Jing-Jing,Wang Li,

物理学报 , 2011,
Abstract: Emergence is one of the important characteristics of complex systems. At present, there is no definite conclusion on what emergence is and how it happens. Swarm model is selected for theoretical research. For convenience of doing so, its specific definition is given, and then the kinetic properties of this model are analyzed. By viewing the energy property, it is proven that under special circumstances the mean square deviation of each kinetic parameter would fall into a certain value space. Experimental results show that under certain conditions, by setting the initial state and parameters of the control equations, the behavior of Swarm can be effectively constrained.
Progress of molecular genetic research on pseudoachon-droplasia and multiple epiphyseal dysplasia

WANG Jing-Jing,GUO Yi-Bin,

遗传 , 2008,
Abstract: Pseudoachondroplasia (PSACH) and multiple epiphyseal dysplasia (MED) belong to the family of bone dysplasia disorders, which are both genetically and phenotypically heterogeneous. Both disorders are caused by mutations in the cartilage oligomeric matrix protein (COMP). COMP is a member of the thrombospondin (TSP) family, which plays an important role in skeletal development. In this paper, we mainly review the latest advances on the structure, function of COMP. We also discuss the types of COMP mutations, the detection methods and the relationship between the COMP gene and these two diseases.
