Clinical study on treatment of vascular cognitive impairment of qi deficiency and blood stasis syndrome with Qizhi Tongluo Capsule:a randomized, double⁃blind, and placebo⁃controlled trial
Objective,2,To observe the clinical efficacy of Qizhi Tongluo Capsule in treating vascular cognitive impairment (VCI) of qi deficiency and blood stasis syndrome.,Methods,2,Ninety patients with VCI of qi deficiency and blood stasis syndrome were randomly divided into a treatment group (,n,=60) and a control group (,n,=30), and both groups were given basic treatment. The treatment group was additionally administered with Qizhi Tongluo Capsule and the control group was given Qizhi Tongluo Capsule mimics. The treatment course was 24 weeks. The clinical efficacy was observed, and the changes in the TCM syndrome scores as well as the scores of the Mini-mental State Examination (MMSE), the Clock Drawing Test (CDT) and the Hopkins Word Learning Test (HVLT) were compared. The safety evaluation was performed.,Results,2,①During the trial, there were 3 drop-out cases in the treatment group and 2 drop-out cases in the control group, and 85 cases finally completed the trial, including 57 cases in the treatment group and 28 cases in the control group. ②The total clinical effective rate of the treatment group was 94.74%, and that of the control group was 53.57%; the clinical efficacy of the treatment group was better than that of the control group (,P,<,0.01). ③The scores of qi deficiency syndrome scale and blood stasis syndrome scale decreased in both groups after treatment (,P,<,0.01); the scores of qi deficiency syndrome scale and blood stasis syndrome scale in the treatment group were lower than those in the control group (,P,<,0.01). ④The MMSE, CDT, and HVLT scores increased in the treatment group after treatment (,P,<,0.05); the differences in MMSE, CDT, and HVLT scores between the two groups were statistically significant after treatment (,P,<,0.05). ⑤No serious adverse reaction was observed in both groups during the trial.,Conclusion,2,Qizhi Tongluo Capsule has achieved satisfactory results in treating vascular cognitive impairment of qi deficiency and blood stasis syndrome, and it can significantly improve the cognitive dysfunction and TCM syndromes of patients with good safety.
