ABSTRACT
Objective To improve the accuracy of prescription checking and provide reference for rational drug administration. Methods Intervention mistakes exsisting in prescription checking in 2016 were retrospectively studied to analyze pharmacist' s misunderstanding during prescription checking. Results The error rate of prescription intervention was higher in department of cardiology, department of general internal medicine and department of neurology, accounting for 0.6％, 0.24％ and 0.23％, respectively.Inaccurate prescriptions for intervention, inaccurate medication and inaccurate repeat injections ranked the top 3 of erroneous prescriptions, with the proportions of 25.11％, 22.98％ and 17.45％, respectively. Conclusion Pharmacists should regularly summarize the misconceptions existed in the prescription audit, take individualized medication thoughts as guidance, strengthen the multi-disciplinary knowledge learning.
ABSTRACT
Objective To explore the relationship between operation scores and the expression of caveolin-1 ( Cav-1 ) protein in the cortex of mice.Methods Male Kunming mice were used and divided into two groups (excellent group and bad group) according to the training scores after 4 days' Y-maze learning training.The expression of cav-1 protein in cortex and hippocampus of the mice with different scores were measured through Western blot technology.Results Cav-1 protein expression of excellent group( Cav-1/β-actin was 5.71 + 1.11 ) in the cortex was significantly higher than that of the bad group ( Cav-1/β-actin was 1.69 + 0.20) (P ＜ 0.01 ).While there was no significant difference in the two groups in the expression of Cav-1 protein in hippocampus(P ＞ 0.05 ).Conclusion The operation scores have distinct correlation with the expression of Cav-1 protein in the cortex of mice.
ABSTRACT
Objective To investigate the effects and mechanisms of Alpinia oxyphylla fructus (AOF) on learning and memory in D-galactose induced brain aging mice. Methods The brain aging model was induced by s. c D-galactose. Learning-memory ability was tested by passive avoidance test and Morris water maze test, and the expression of synapsin ( Syn), mitogen-activated protein kinase (MAPK) and protein kinase ( PKC ) in hippocampus were examined by Western blot. Results ① Passive avoidance test:the latency in brain aging group( ( 119.80 ±101.80)s) significantly decreased,and the number of errors (4.4 ± 1.3 ) significantly increased compared with the control group( latency: (279.30 ± 31.64) s; number of errors: ( 1. 8 ±0.9), P＜0. 01 ) ). The latency in low dose, middle dose and high dose AOF group( ( 170.25 ± 68.31 ) s, (226.31 ± 73.25 ) s, (263.20 ± 70.55 ) s) significantly increased, and the number of errors in middle dose and high dose AOF group ( ( 2.8 ± 1.2 ), ( 2.3 ±0. 9 ) ) significantly decreased compared with brain aging group (P ＜ 0. 05, P ＜ 0. 0 1 ). ② Morris water maze test:the escape latency in brain aging group was significantly longer, and the time spent in the original quadrant that previously contained the platform was significantly shorter compared with the control group (P＜0. 01 ). The escape latency in 3 AOF groups was significantly shorter (P＜ 0. 05 ), and the time spent in the original quadrant that previously contained the platform in middle and high dose AOF groups was significantly longer compared with brain aging group (P＜0. 05, P＜0. 01 ). ③ Western blot test:the expression of Syn,MAPK and PKC in hippocampus of brain aging group was significantly weakened than that of the control group. In contrast, the expression of Syn,MAPK, PKC were significantly enhanced in all AOF groups. Conclusion AOF could significantly improve the ability of learning and memory in brain aging mice. Its effects might be related to the increase of the expression of Syn, MAPK and PKC in hippocampus.
