Methods： A total of 33 PPPD patients were randomly divided into test group and control group. Two groups of patients were given psychological treatment. The test group was given XJP and the control group was given escitalopram. The course of treatment was 12 weeks. Before and after 4 weeks and 8 weeks and 12 weeks, the dizziness handicap inventory （DHI）, Hamilton anxiety scale （HAMA） and Hamilton Depression scale （HAMD） were used to evaluate the treatment effect. Results： The total scores of HAMA, HAMD, DHI and the respective factor scores of DHI significantly decreased in both groups after 4 weeks of treatment compared with those before the treatment （P 〈 0.01）. The DHI scores and the score of function, physiology at 8-week, 12-week, as well as the HAMA and HAMD scores at 4-week, 8-week, 12-week in the test group were significantly lower than those in the control group （P 〈 0.05）. The incidence of adverse reactions in the test group was significantly lower than the control group （P 〈 0.05）. Conclusion： XJP can improve the clinical symptoms of patients with PPPD. It can both improve the physical and functional symptoms of PPPD and reduce anxiety and depression. In the course of treatment, the adverse reaction of the prescription is less and mild. It has the advantages of high efficiency, safety, low price and easy access to materials.展开更多
