The effect of chlorimipramine on the spontaneous contraction of isolated duodenal smooth muscle of rabbits
WANG Lei, XIA Shuai, GONG Yushuang, WANG Na, SUN Yuqi, JIANG Shujun
Objective
To investigate the effect of chlorimipramine (CIMP) on the spontaneous contraction of duodenal smooth muscle of rabbits in vitro and its mechanism.
Methods
The isolated intestinal tubes of rabbits were made.The technique of perfusion of isolated duodenum was used to record duodenal smooth muscle contraction curve.The influence of CIMP on the spontaneous contraction of duodenal smooth muscle was observed and the mechanism of CIMP was studied with pharmacological methods.
Results
CIMP reduced the amplitude of spontaneous contraction of duodenal smooth muscle in a dose-dependent manner,while the frequency was not obviously influenced.CIMP inhibited the enhanced contraction of duodenum smooth muscle induced by acetylcholine.CIMP also inhibited the contraction of duodenum smooth muscle induced by calcium chloride application in the calcium-free Tyrode’s solution.ACh and CaCl
2
were added successively into calcium-free Tyrode’s solution,and CIMP was not effective on the release of internal calcium, but inhibited external calcium flow in the dose-dependent manner.
Conclusion
CIMP obviously inhibits the spontaneous contraction of duodenal smooth muscle of rabbits in vitro. Suppression of M receptor and inhibition of the extracellular calcium influx via cell membrane might be involved in the process.

Investigation on short-term compliance and influencing factors of young and middle-aged discharged patients with coronary heart disease
CUI Jianguo, XU Wenwen, ZHANG Qingtan, MI Baobin, MA Hui, YAN Xiaohong, QI Jie
Objective
To investigate the current status of short-term treatment compliance and related factors in young and middle-aged patients with coronary heart disease (CHD).
Methods
A total of 258 young and middle-aged patients with coronary heart disease were followed up 6 months. Questionnaires were carried out to assess general conditions,social supports, medication compliance, etc. The relationship between above indexes and treatment compliance status were analyzed.
Results
102 patients were with better treatment adherence and 156 patients with poorer. The single factor analysis showed that the compliance of the patients with coronary heart disease was significantly related to the monthly per capita income, the education level, the knowledge of coronary heart disease,and the social support.The incidence of major adverse cardiovascular events (MACE) in patients with poor compliance was significantly higher than that in patients with good compliance. Multivariate logistic regression analysis showed that the low score knowledge of CAD , poor social support and low per capita income were the independent factors that led to the poor compliance of the middle-aged and young patients with coronary heart disease.
Conclusion
The short-term treatment compliance of young and middle-aged patients with coronary heart disease after discharge was not optimistic. Cognition and knowledge of coronary heart disease,social support and family per capita income were independent factors that affect the treatment compliance of young and middle-aged patients with coronary heart disease.
