AIM: To study the expression of endostatin in ischemic myocardium of myocardial infarction(MI) rats in various periods and the correlation with VEGF expression and microvascular density(MVD).METHODS: Thirty-two male Sprague-Dawley rats after myocardial infarction were randomly divided into 7,14,21 and 28 days group.The sham group was normal control group(eight rats in each group).The expression of endostatin,VEGF and MVD in ischemic myocardium were observed by immunohistochemistry.RESULTS: The expression of endostatin significantly increased in the ischemic myocardium after MI,peaked at 7 days,then gradually decreased at 14,21 and 28 days.The endostatin level at 28 days was the same as the shams.The changing trends of expression of endostatin in ischemic myocardium after MI were similar to that of VEGF and were significantly correlated with the MVD.CONCLUSION: The expression of endostatin increased in ischemic myocardium of myocardial infarction rats.The changing trends of endostatin were similar to that of VEGF and positively correlated with the MVD.These data suggest that endostatin may modulate ischemic myocardium angiogenesis after myocardial infarction.

Quantitative NMR (qNMR) is a technology based on the principle of NMR. This technology does not need the references of the determined components, which supplies a solution for the problem of reference scarcity in the quantitative analysis of traditional Chinese medicines. Moreover, this technology has the advantages of easy operation, non-destructiveness for the determined sample, high accuracy and repeatability, in comparison with HPLC, LC-MS and GC-MS. NMR technology has achieved quantum leap in sensitivity and accuracy with the development of NMR hardware. In addition, the choice of appropriate experimental parameters of the pre-treatment and measurement procedure as well as the post-acquisition processing is also important for obtaining high-quality and reproducible NMR spectra. This review summarizes the principle of qHNMR, the various experimental parameters affecting the accuracy and the precision of qHNMR, such as signal to noise ratio, relaxation delay, pulse width, acquisition time, window function, phase correction and baseline correction, and their corresponding optimized methods. Moreover, the application of qHNMR in the fields of quantitation of single or multi-components of traditional Chinese medicines, the purity detection of references, and the quality analysis of foods has been discussed. In addition, the existing questions and the future application prospects of qNMR in natural product areas are also presented.
