Objective To investigate the inhibitory effect on enhancement of contraction and relaxation functions of cardiomyocytes induced by of MN9202 TEA, Forskolin, and MB. Methods The twitch amplitude was measured with a video edge tracker method. The following indexes, including ph (peak height), peak height/baseline percent (ph/bl, %), maximal velocity of contraction (+dL/dt) and maximal velocity of diastolization (-dL/dt), were recorded by a computer. Results TEA, Forskolin and MB increased electrically-induced contraction as shown by the following indexes: ph, ph/bl%, +dL/dt and -dL/dt. Forskolin and MB markedly augmented function of cardiac myocyte contraction and diastolization. Comparing with the control group, Forskolin (10-8mol/L) increased ph from 0.12?0.03(um)to 0.24?0.06 (um), ph/bl % from 12?3% to 27?6%, +dL/dt from 1.8?0.5 (um/s) to 3.8?0.9 (um/s), -dL/dt from 1.8?0.22 (um/s) to 3.5?0.7 (um/s). These indexes increased by 91%, 123%, 110% and 89%, respectively. MB also increased significantly; ph, ph/bl %, +dL/dt and -dL/dt were 0.14?0.04um, 11?4%, 2.2?0.3um/s and 2.2?0.6um/s, respectively. MN9202 (3?10~ -6mol/L) decreased the indexes (+dL/dt and -dL/dt ) which were increased by Forskolin significantly. Conclusion TEA, Forskolin and MB increased function of cardiac myocyte contraction and diastolization. These drugs might elevate intracellular calcium content indirectly and directly. The effects of TEA, Forskolin and MB were attenuated by MN9202. MN9202 might not only block Dihydropyridine Receptor, but might also inhibit calcium influx. Further study is needed to elucidate exact mechanism of MN9202.

Objective:To summarize the drug repercussion data in outpatient pharmacy and analyze the reasons to provide sugges-tions for the improvement. Methods: The information was collected from the hospital information system ( HIS) during January 1, 2013 and December 31, 2015, including drug name, category, quantity, amount, reasons for drug repercussion and the other statisti-cal data. Results:During the three years, the number of prescription drugs, amount of money and varieties of drug repercussion were increased. The most common reasons for drug repercussion were the other reasons, withdrawn by doctors and the request of patients. The sum of drug repercussion was positively correlated with the drug price and the amount of drug repercussion. Conclusion:The op-tion simplicity for drug repercussion in HIS is the main reason for drug repercussion bythe other reasons. The occurrence of drug re-percussion should be intervened by such methods as gradually improving the HIS, establishing intervention measures, enhancing the professional quality of pharmacists and so on.
