Objective To evaluate the effect of Tirofiban on CRP levels in patients with acute myocardial infarction (AMI) after primary emergency percutaneous coronary intervention (PCI). Methods Eighty-four AMI patients admitted on emergency were randomly divided into two groups: (1) early-treated group (n=45), immediately receiving Tirofiban intravenously on admission and (2) late-treated group (n=39), receiving Tirofiban intravenously after coronary angiography was performed. TIMI grading before and after PCI in beth groups were compared, CRP levels before and three days after PCI were estimated. The major adverse cardiovascular events (MACEs) occurred during hospitalization and following-up period of three months were recorded. Results Before PCI, TIMI grade 3 forward flow rate in early-treated group was significantly higher than that in late-treated group, while no significant difference existed between two groups after PCI. Three days after PCI, CRP level in early-treated group was markedly lower than that in late-treated group. During hospitalization, the occurrence of MACEs in early-treated group was lower than that in late-treated group, while no marked difference was found between two groups during the following-up period of three months. Conclusion In treating AMI patients with primary PCI, Tirofiban should be used as early as possible, which is safe and effective for PCI and can also significantly improve forward blood flow in target vessels, decrease the ClIP level and reduce the occurrence of MACEs during hospitalization.

Haloacetic acids are the main disinfection by-products in chlorinated drinking water,which are known or suspected to carcinogenic. Many countries have promulgated haloacetic acids as the routine monitoring item for drinking water safety. In order to better control the formation of haloacetic acids in chlorinated drinking water,many techniques and analysis methods were exploited. This review summarized the development of techniques and analysis methods and the comparative analysis was conducted in technique cost,method detection limit,sensitivity,resistance to disturb and sample pretreatment. The electrospray mass spectrometry is the best choice,but the instrument and operation cost is much higher,so the standard method based on the gas chromatography will still be the popular method for drinking water quality analysis.
