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:"Premature coronary artery disease (CAD) and its risk factors are highly prevalent in Iran. It is well documented that atherosclerosis starts in childhood and there is evidence that this association with adult levels may originate at birth, so assessment of serum lipid levels in neonates might be of importance. In this study we aimed to measure serum lipoprotein and apolipoprotein levels in a representative sample of Iranian newborns. Cord blood lipid profile, apolipoprotein A, apolipoprotein B, and lipoprotein a (LPa) were analyzed in 378 full-term, Iranian newborns. The mean values of total cholesterol (TC), low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), apolipoprotein A, apolipoprotein B, and Lpa in girls were 81.4 +/- 28.3, 35.9 +/- 22.4, 31.1 +/- 9.9, 87.9 +/- 20.2, 34.2 +/- 18.2, and 21.0 +/- 2.8 mg/dL, respectively; these values in boys were 75.2 +/- 21.1, 32.1 +/- 16.3, 28.8 +/- 8.7, 84.3 +/- 16.0, 32.6 +/- 14.2, and 19.5 +/- 2.7 mg/dL, respectively. Median values of triglycerides (TGs) in boys and girls were 61 and 62 mg/dL, respectively. Female neonates had significantly higher concentrations of TC and HDL-C than males (81.4 +/- 28.3 vs. 75.2 +/- 21.1, p = 0.02, and 31.18 +/- 9.97 vs. 28.8 +/- 8.7, p = 0.02, respectively). Other biochemical factors were not significantly different between genders. The mean and median concentrations of LPa were 20.3 and 18.7 mg/dL, respectively, which are almost five times higher than those reported in some other studies. The TG concentration was 1.5-2 times higher than those previously reported. Our findings indicate that serum concentrations of LPa and TG in Iranian neonates are higher than those in previous studies; this disorder, which is likely placing Iranians at increased risk for future CADs, needs to be assessed in longitudinal studies."
