Clinical study of Jiawei-Xiaoxianxiong decoction combined with conventional western medicine therapy in the treatment of refractory angina pectoris with Qi stagnation and blood stasis syndrome / 国际中医中药杂志

ABSTRACT

Objective@#To observe the clinical effect of Jiawei-Xiaoxianxiong decoction combined with conventional western medicine for the refractory angina pectoris with Qi stagnation and blood stasis syndrome and to explore its mechanism.@*Methods@#A total of 98 patients who met the inclusion criteria were divided into two groups according to the random number table method, 49 in each group. The control group was treated with conventional therapy. The study group was treated with Jiawei-Xiaoxianxiong decoction on the basis of the control group. Both groups were treated for 4 weeks. The symptom of angina pectoris was scored before and after treatment. The Serum level of cardiotrophin-1 (CT-1), cytochrome C (Cyt C), soluble intercellular adhesion molecule-1 (sICAM-1), von Willebrand Factor (vWF), MDA and SOD were measured by ELISA, and the clinical effect was evaluated.@*Results@#The total effective rate was 75.5% (37/49) in the study group and 63.3% (31/49) in the control group. There was significant difference between two groups (χ2=5.235, P=0.022). After treatment, the level of CT-1 (105.19 ± 12.04 ng/L vs. 158.25 ± 14.18 ng/L, t=19.967), Cyt C (0.53 ± 0.11 ng/L vs. 0.81 ± 0.15 ng/L, t=10.537) in the study group were significantly lower than those in the control group (P<0.01); the serum level of sICAM-1 (261.13 ± 38.40 μg/L vs. 415.55 ± 42.26 μg/L, t=18.930), vWF (105.22 ± 18.63 μg/L vs. 145.57 ± 21.18 μg/L, t=10.013), MDA (4.80 ± 0.59 mol/L vs. 6.21 ± 0.87 mol/L, t=9.389) in the study group were significantly lower than those of the control group (P<0.01); the SOD (12.07 ± 1.84 mol/L vs. 10.89 ± 1.65 mol/L, t=3.342) level in the study group was significantly higher than that of the control group (P<0.01). The number of attacks, duration, degree of pain, nature of pain and nitroglycerin dosage in the study group were significantly lower than those in the control group (t=9.711, 11.521, 8.818, 13.922, 17.791, respectively, all Ps<0.01).@*Conclusions@#The Jiawei-Xiaoxianxiong decoction combined with routine western medicine therapy can improve the symptoms of angina and clinical efficacy in patients with refractory angina pectoris of Qi stagnation and blood stasis syndrome. It is speculated that its mechanism may be related to anti-myocardial cell apoptosis, alleviating vascular endothelial injury and antioxidation.
