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 The most common reasons for drug repercussion were the other reasons, withdrawn by doctors and the request of patients.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.

Objective To evaluated the effect of first-line epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI)on advanced non-small cell lung cancer (NSCLC)patients with different EGFR mutation status (exon 1 9 deletion and exon 21 mutation).Methods Seventy-two advanced NSCLC patients with EGFR mutation confirmed by histopathology were enrolled.All of the patients received first-line EGFR-TKI.The relationships between EGFR mutation status and objective response rate (ORR),disease control rate (DCR),progression free survival (PFS ) and overall survival (OS ) were analyzed.Results Of the 72 patients,37 patients expressed exon 1 9 deletion,35 patients expressed exon 21 mutation,and all of them could be evaluated.The ORR and DCR of patients with exon 1 9 deletion were higher than those of patients with exon 21 mutation (75.7%vs.51 .4%,χ2 =4.583,P=0.032;89.2%vs.68.6%,χ2 =4.636,P=0.031 ).The modified median PFS of patients with exon 1 9 deletion was significantly higher than that of patients with exon 21 mutation (1 3.2 month vs.1 0.8 month,χ2 =4.700,P=0.030).The median OS of patients with exon 1 9 deletion was significantly higher than that of patients with exon 21 mutation (30.2 month vs.25.6 month,χ2 =4.686,P=0.030).The side effects were similar between the two groups.The most common adverse reaction was rash,and the incidence had no significant difference between the two groups (48.7% vs.48.6%,χ2 =0.000,P=0.995 ).Conclusion EGFR mutation status is a predictor for PFS,OS and ORR of first-line EGFR-TKI in patients with advanced NSCLC.NSCLC patients with EGFR exon 1 9 deletion are associated with longer survival time and better response rate compared with those with exon 21 mutation.

Objective:To evaluate the uncertainty in the determination of lamotrigine(LTG)in human plasma by LC-MS/ MS. Methods:The uncertainty sources in the determination of LTG were analyzed and the uncertainty was evaluated and combined. Re-sults:The expanded uncertainty of LTG at low(0. 050 4 μg· ml - 1 )and high(1. 27 μg· ml - 1 )concentrations was 0. 005 18 μg· ml - 1 and 0. 066 4 μg· ml - 1 ,respectively(P = 95% ,k = 2). Conclusion:The uncertainty in the determination of LTG in human plasma by LC-MS/ MS is mainly caused by the protein precipitation recovery,matrix effect and sample preparation at low concentration, and by the matrix effect,sample preparation and repeatability at high concentration.

Objective To evaluate the effects of hydroxyethyl starch (HES) on the renal function and blood coagulation of patients with acute pancreatitis (AP). Methods 151 patients with acute pancreatits were divided into treatment group (treated with HES, n=62) and control group (treated with crystalloid solutions, n =89). The two groups were compared by retrospective analysis of the indices such as serum creatinine (Scr), blood urea nitrogen (Bun), platelet count(Plt), prothrombin time activity (PTA), international normalized ratio (INR), activated partial thromboplastin time (APTT) and fibrinogen (FIB) before and after treatment. Results Before hospitalization, there were insignificant differences in respect of Scr and Bun in the two groups respectively. But at discharge, Scr and Bun in the treatment group were significantly increased (P<0.05), while Bun was significantly decreased 24 h right after infusion of crystalloid solutions in the control group (P<0.05). There were no differences between the two groups in terms of Scr and Bun. As for indices of coagulation, APTT in the treatment group was significantly increased after infusion of HES (P<0.05). The hospital stay in the treatment group was longer than the control group (P < 0.05). Conclusions HES may adversely affect renal function and intrinsic pathway of blood coagulation of patients with AP. Renal function and blood coagulation should be monitored when using HES.
