Each group had 50 patients. The drug group was treated with escitalopram for 6 weeks.The acupuncture group were treated with escitalopram and electroacupuncture for 6 weeks. We compared the HAMD24 among 3 groups before or after treatment. The correlation of the levels of IL-1 β, IL- 2, IL- 6, TNF-α and the total HAMD24 score among 3 groups were taken by the correlation analysis. And the main factors influencing the total HAMD24 score before the study were analyzed by the multiple inear step regression method. Results Compared with the pre-treatment group, the HAMD score of the drug group and the acupuncture group decreased after treatment, the difference was statistically significant (P<0.05 or P<0.01). Compared with the drug group, the HAMD score of the acupuncture group was lower after treatment; the difference was statistically significant (P<0.05 or P<0.01).

Superoxide dismutase (SOD) activity, reduced glutathione (GSH) and malondialdehyde (MDA) levels were measured, and their correlations with ultrasound parameters were evaluated. Results The ultrasound-related parameters of rats in the PAH group changed significantly and gradually increased.HE and Masson staining showed that cardiac myocytes were enlarged and collagen fibers in myocardial interstices were increased, and it was more obvious in the 4-week group.In the PAH group, the SOD activity and GSH levels were lower, while the MDA levels were higher, and there was a trend of change, and there was a significant correlation with ultrasound parameters. The difference was statistically significant (P<0.05). Conclusion PAH causes changes in the myocardial tissue structure of the rat right ventricle, as well as changes in oxidative stress-related indicators.
