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:"Transcoronary transplantation of progenitor cells has been proposed as a novel therapy for ischemic heart failure. The primary aims were to assess the feasibility of obtaining CD34+ cells from blood without mobilization in chronic conditions and to compare homing with results reported in acute conditions. We also evaluated the effect of CD34+ on endothelial function. In 7 patients with a history of an anterior myocardial infarction (20 +/- 2 months), a large amount of CD34 (18.2 +/- 3.0 x 10(6)) were obtained and an intracoronary infusion into the left anterior descending artery via an over-the-wire balloon catheter was performed. Myocardial homing involved 3.2% +/- 0.6% of injected cells. Endothelial function studied with increasing doses of bradykinin was not significantly modified after 3 months. In the treated group, compared with 5 nonrandomized control patients with a similar clinical history, the only echocardiographic significant change (2-way analysis of variance) was a decrease in end-systolic volume (P < 0.03). In conclusion, large amounts of CD34+ cells can be obtained from blood, without mobilization, in the chronic phase of myocardial infarction. As reported in the acute situation 1 hour after treatment, intracoronary infusion of CD34+ cells results in myocardial homing of a few percents of the cells. In this small group of patients, no effect of this therapy is detected on the endothelial function and only marginal changes are observed on echocardiographic parameters."
