There is compelling evidence that chronic inflammation predisposes to biliary tract cancer. Previously we found that aspirin use and variants in the PTGS2 gene, both of which are closely linked to inflammation, were associated with biliary tract cancer risk in a population-based study in China. To test the inflammation hypothesis further, we examined the associations of variants in 20 genes involved in the inflammation pathway with risk of biliary tract cancer and stones in a large population-based case-control study in Shanghai, China. We genotyped 56 single nucleotide polymorphisms (SNPs)from 20 inflammation genes in 411 biliary tract cancer cases (237 gallbladder cancers, 127 extrahepatic bile duct cancers, and 47 ampullary cancers), 895 subjects with biliary stones, and 786 population controls. Unconditional logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (Cls) for the association of individual SNPs and haplotypes with biliary stones and biliary tract cancer risk. Of the 56 SNPs examined, 20 showed some associations with biliary cancer and stones. Specifically, variants of the IL8, IL8RB, RNASEL, TGF-beta, and TNF-alpha genes were associated with gallstone risk, while variants in the IL1A, IL10, VEGF, and RNASEL genes were associated with gallbladder cancer risk. Adjustment for multiple comparisons did not materially change these results. Of the 10 genes with multiple SNPs, we inferred halotypes; only one haplotype in the IL8RBgene was associated with gallstones. The haplotype frequency was significantly different between bile dict cancer cases and control (p=0.007). A haplotype comprising 3 SNPs in the IL8RB gene (rs2230054, rs1126579, rs1126580) was associated with a 54% increased risk of bile duct stones (95% CI 1.14-2.07, p=0.02), relative to the most frequent haplotype. In summary, common variants in immune-related genes influencing inflammatory responeses were associated with gallstones and biliary tract cancer, lending further support to the role of inflammation in the pathogenesis of biliary stones and biliary tract cancer. Future larger studies with more complete gene coverage are needed to confirm these results.

The purpose of this study is to draw a general conclusion through summing up theses on parents' need for their education up to the present. The subjects of this study are 25 masters' degree theses on parents' need for their education in the kindergarten from 2001 to 2010. The results of data on parents' education method and style were conducted by frequency analysis. Also it was surveyed if in how many theses the contents of parents' education were rated over average points by Licker. The results of this study are as follows: First, the parents think that the proper frequency of their education is once or two in a semester and the favorite time is from 10 to 12 o'clock or from 2 p. m. to 4 p.m. They also want to learn on Wednesday, Friday and Saturday. And they want a professional as their lecturer the most and then a homeroom teacher. Secondly, in the survey of their education style they like more lecture or a short course than any other thing, and then they like home messenger, group council and so on. But especially they don't like the style of visiting class, book lending, ceremony/class assistance, practice (workshop), and visiting home. Thirdly, they want to know a general guide in the kindergarten of the contents of their education a lot. And they want to know some of a budget, program, and assessment of a principal and the teachers in the kindergarten. Fourthly, they want to know all parts of the parents' roles related to rearing their children in their own elements of the contents of their education above all. And they also want strongly their free time, hobby, the liberal arts, amusement and recreation. Fifthly, in the view of infant development they want strongly to know how to communicate with their children rightly, and how to adjust their children's activities and how to praise or blame their children. And they also want how to form their children's right habit and to guide their children's right acts in the infant period the most. Lastly, they want to know children's physical development and their cognitive development in the view of infant development the most. And then they want to know the development of sociology, creativity, morality, and emotion in good order.
