Therapy of Suppressing Yang and Astringing Yin for the Treatment of Cancer-Related Insomnia

The pathogenesis of can cer-related in som nia(CRI)mainly in eludes,first,the flow of cancerous toxin leading to the disorder of visceral qi;second,cancer-related radiotherapy and chemotherapy belonging to"exogenous pathogenic factors"to a certain extent,which can further aggravate visceral disorders.The therapeutic principle of Chinese medicine is to tranquilize the mind on the basis of regulating viscera,suppressing yang,and astringing yin.On this theoretical basis,Professor Zheng Yuling created a representative prescription of Zhenjing Anshen Granules(镇静安神颗粒)which can achieve the co-regulation of the heart,liver,and kidney,tranquilizing the mind and nourishing the blood.Clinically,the selection of prescriptions and medicines needs to be considered due to factors such as different treatment stages and differ-ences in patients'constitutions.

Effect of Chinese Herbal Medicine for Calming Gan(肝) and Suppressing Hyperactive Yang on Arterial Elasticity Function and Circadian Rhythm of Blood Pressure in Patients with Essential Hypertension

Objective：To observe the effect of Chinese herbal medicine for calming Gan（肝） and suppressing hyperactive yang（平肝潜阳,CGSHY） on arterial elasticity function and the circadian rhythm of blood pressure in patients with essential hypertension（EH）.Methods：Adopting a parallel,randomized design,sixty-four patients with EH of stagesⅠandⅡwere randomly divided into two groups according to a random number table,with 32 in each group.The patients in the treatment group were treated with CGSHY and those in the control group were treated with Enalapril.All patients were given 24-h ambulatory blood pressure monitoring（ABPM） before and after a 12-week treatment.Trough/peak（T/P） ratios of systolic and diastolic blood pressure（SBP DBP） of each group were calculated.The circadian rhythm of their blood pressure was observed at the same time. The changes in elasticity of the carotid artery in the patients,including stiffness parameter（β）,pressure-strain elastic modulus（Ep）,arterial compliance（AC）,augmentation index（Al）,and pulse wave velocity（PVWβ） were determined by the echo-tracking technique before and after a 12-week treatment.In the meantime,their levels of nitric oxide（NO） and endothelin-1（ET-1） were measured respectively.Results：After treatment,all parameters in the 24-h ABPM and the elasticity of the carotid artery（β,Ep,AC and PVWβ） were markedly improved,the level of NO was increased,and ET-1 was decreased in both groups as compared with values before treatment （P0.05 or P0.01）.Further,the improvements in the ratio of T/P of SBP DBP and in the level of NO and ET-1 in the treatment group were more significant than those in the control group（P0.05）.There were no significant differences in all parameters in the ABPM monitoring and the elasticity of the carotid artery,the recovery of blood pressure circadian rhythm,and the therapeutic effect of antihypertension in EH patients between the two groups （P0.05）.Conclusions：Chinese herbal medicine for CGSHY may lower the blood pressure smoothly and recover the circadian rhythm of blood pressure in EH patients.They may also improve the carotid elasticity of EH patients similar to that of Enalapril.The mechanism of action of Chinese herbs on EH might be related to the regulation of vascular endothelium function.
