How to Build CHD@ZJU

CHD related Articles were retrieved from Pubmed, by entering keywords "coronary heart disease" and constrict the publish date from 2000/1/1 to now (2013/1/23). As a result, totally 115898 articles were found and their abstracts were downloaded for text mining. Since some articles didn't contain abstracts, only 88396 abstracts remained.
The text-mining process to get CHD related genes could be divided in to 5 following steps:

  • 1) Extracting all keywords from abstracts and ignoring those keywords start with numbers. 101402 keywords were extracted.

    •
  • 2) Input these keywords into Gene library in ArrayTrack and find possible related genes. 4674 genes were then found.

  • 3) Put these 4674 genes again into pubmed abstracts to find related aticles. Only genes which offical name or there keyword description (such as prolactin for gene PRL) could be found in the abstract would be remained. As a result, 1247 genes were remained.

    •
  • 4) Manually examined on the 1247 genes to validate it was acutally related to CHD. Some genes would be filtered if it represents other meanings (such as gene CAD, Entrez ID:790, carbamoyl-phosphate synthetase 2, is mostly meant coronary arterial disease in articles). 681 genes were then validated with at least one reference.

  • 5) All genes was compared with 1078 CHD genes in RGD database, and 370 genes were overlapped. These 370 genes were labels as "RGD_Supported" and the other 293 genes were labels as "REFERED". All 663 genes had supported references in CHD@ZJU which were examined by step 4.

  • Abstract:"We analyzed the relationship between the IVS1-397T > C polymorphism of estrogen receptor alpha gene and inflammatory response of eighty postmenopausal women with an established coronary artery disease (CAD). We found that the IVS1-397T allele carriers exhibited an enhanced inflammatory response in vivo and in vitro. These patients had a higher number of total monocytes and their CD14(+)CD16(+) inflammatory subset in relation to CC homozygotes. The CT and TT women's LPS-stimulated whole blood cell cultures produced more IL6 and TNFalpha than did the cultures of CC women. Moreover, significantly more of the T allele patients had major post-coronary artery bypass grafting complications and less of them experienced subjective angina pectoris improvement. Summarizing, the IVS1-397T > C polymorphism allows us to identify a group of postmenopausal women with the strong inflammatory response which is associated with a higher incidence of the major post-CABG adverse cardiovascular complications."
