Objective: To investigate the effects of Migaoxinle Drop Pills (Migao Cinnamon anel Bulbus Allii Macrostemi) (MDP) on cats with experimental myocardial ischemid.Methods: The coronary arteries was ligated to establish myocardial ischemic model and MDP was given through duodenum to observe its effects on myocardial ischemic limit and myocardial infarct area by N BT staining.Results: MDP could reduce the myocardial ischemic limit and myocardial infarct area.Conclusion: MDP could protect myocardia from ischemic damage.

AIM: To investigate the CPU86017 and its enantiomers inhibit abnormal gene expression of calcineurin and NFκB in rat cardiomyopathy induced by L-thyroxin and compare the effect of CPU86017 (racemate) with its 4 enantiomers: (7S, 13R), (7S, 13S), (7R,13S), and (7R,13R)-CPU86017 in this model. METHODS: The animals were randomly divided into 7 groups. The rat hypertrophied model was produced by treatment with L-thyroxin 0.2 mg·kg-1·d-1, sc for 10 d and treated with CPU86017 or its enantiomers 4 mg·kg-1·d-1, sc from d 6 to d 10. The changes in left ventricular (LV) weight index, redox system, and the NO and iNOS activity in the myocardium were investigated. The expression of mRNA of calcineurin、NF-κB in the left ventricle was measured. RESULTS: There were significant cardiac hypertrophy and oxidative stress in rats treated by L-thyroxin. The expression of calcineurin, NFκB mRNA were upregulated (P<0.05, compared with that of control). After treatment with CPU86017 (racemate and enantiomers), LV remodeling and the redox system were improved. CPU86017 and (7S,13R)-CPU86017 showed a better improvement on LV remodeling and the redox than the other isomers and restored the normal expression of calcineurin, NF-κB (P<0.05, P<0.01), respectively. CONCLUSION: It suggested that an up-regulation of calcineurin and NFκB possibly related to the altered intracellular calcium handling system plays a role in the progression of L-thyroxin induced cardiomyopathy and CPU-86017 and its 7S,13R-CPU86017 enantiomer effectively inhibit the abnormal expression of calcineurin and NFκB genes, the NOS enzyme and oxidant stress in the cardiomyopathy.

OBJECTIVE To evaluate th e effects of comprehensive drug cost control in China ，and to provide reference for further improving the effects of cost control. METHODS Entropy method was used to establish a comprehensive evaluation index system of the comprehensive drug cost control effect from the respective of drug price control ability ，drug cost control ability and patient affordability. The comprehensively evaluate the effects of drug cost control in 31 provinces （autonomous regions and municipalities）during 2016-2020. The k-means cluster method was used to analyze the effects of comprehensive drug cost control in various provinces. RESULTS & CONCLUSIONS During the period of 2016-2020，the total score of comprehensive drug cost control effect of 31 provinces were 14.64，16.71，17.58，17.57，17.88，respectively. The results of cluster analysis were similar to the ranking of entropy method. Medical and health system reform policy had entered a stable period after achieving phased results ； the effects of comprehensive drug cost control was characterized by regional steps in 31 provinces；the effects of comprehensive drug cost control were better in developed coastal areas and some provinces and cities of western regions ，followed by provinces and cities in central China ；however，comprehensive drug cost control in 3 provinces of northeast China showed poor effect. The effects of comprehensive drug cost control in pilot cities of comprehensive medical reform were significantly improved. It is suggested that the successful experience of pilot cities of comprehensive medical reform should be promoted nationwide ，and policies such as volume-based drug procurement ，medical insurance drug price negotiation ，and diagnosis-related groups / diagnosis-intervention packet payment method reform should be further deepened.
