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:"OBJECTIVE: In patients with coronary artery disease, the concomitant presence of renal function impairment is associated with decreased survival. We aimed to assess whether in coronary artery diseased patients renal function impairment is associated with systemic vascular function, functional parameters of the renin-angiotensin system, or inflammation as potential mediators for cardiovascular risk. METHODS AND RESULTS: We studied 125 patients, 87% male, with a mean age of 62.2+/-8.2 years; 72% had 3-vessel disease, and mean renal function was 74+/-13 mL/min per 1.73 m2. Internal thoracic artery rings were sampled during coronary bypass surgery and used for in vitro vascular measurements. We could not establish an association between endothelium-dependent vasorelaxation (response to methacholine) and renal function. In addition, vascular response to potassium chloride, phenylephrine, and angiotensin II were not associated with renal function. Finally, serum angiotensin-converting enzyme (ACE) activity, usage of ACE inhibitors, C-reactive protein, and soluble intercellular adhesion molecule 1 were not related to renal function. CONCLUSIONS: In coronary artery disease patients, mild renal function impairment is not associated with systemic vasomotor responsiveness, inflammation, or functional systemic parameters of the renin-angiotensin system. The relation between systemic endothelial dysfunction and mild renal insufficiency might be more complicated than previously thought."
