A decision tree model was developed to conduct a cost-effectiveness analysis from the perspective of the healthcare system. The effect parameter was the clinical effectiveness rate obtained from a meta-analysis of clinical literature. The cost parameter was represented by the drug treatment cost. The incremental cost-effectiveness ratio (ICER) was subsequently calculated, and the robustness of the primary analysis results was assessed through one-way sensitivity analysis.[Results] The results of the meta-analysis indicated that, over an 8-week treatment period, the clinical efficacy of Yangxin Dingji capsule in conjunction with conventional Western medicine for the treatment of tachyarrhythmia was superior to that of conventional Western medicine therapy alone, and the difference was found to be statistically significant [ OR =3.32, 95% CI (2.22-4.96), P <0.000 01]. The clinical efficacy of Yangxin Dingji capsule in conjunction with conventional Western medicine for the treatment of tachyarrhythmia was found to be superior when the treatment duration was 4 weeks, and the difference was found to be statistically significant [ OR =2.39, 95% CI (1.45-3.96), P =0.000 7]. The cost-effectiveness analysis indicated that with an 8-week treatment regimen, each 1% increase in the clinical effectiveness rate of Yangxin Dingji capsule in conjunction with conventional Western medical therapy for the treatment of arrhythmia, as compared to conventional Western medical therapy alone, resulted in an increase in cost of 91.78 yuan. Conversely, when the treatment duration was 4 weeks, each 1% increase in the clinical effectiveness rate of the Yangxin Dingji capsule combined with conventional Western medical therapy led to a cost increase of 70.84 yuan.[Conclusions] In the management of tachyarrhythmia, the clinical efficacy of Yangxin Dingji capsule in conjunction with conventional Western medicine therapy is superior to that of conventional Western medicine therapy alone. When the willingness-to-pay value exceeds the corresponding ICER, the combination of Yangxin Dingji capsule with conventional Western medicine therapy is deemed more cost-effective than the use of conventional Western medicine therapy alone.展开更多

This study aimed to investigate the electrophysiological effect of SSYX on the hearts of myocardial-infarcted rabbits and further explore the mechanism by which SSYX alleviates myocardial fibrosis. Myocardial infarction（MI） was established in rabbits by ligation of the left circumflex coronary. The rabbits were treated with SSYX（0.5 g/kg/d） or saline for 8 weeks by oral administration. Microelectrode array（MEA） technology was used in vivo for extracellular electrophysiological recordings of the infarct border zone. Masson＇s trichrome staining was used to observe myocardial fibrosis. Western blotting was performed to evaluate the protein expression levels of collagen Ⅰ（COL Ⅰ） and collagen Ⅲ（COL Ⅲ）. Quantitative real-time polymerase chain reaction（real-time PCR） was performed to evaluate the TGF-β1 and MMP-2 m RNA expression levels. The results showed that the total activation time（TAT） and the dispersion of TAT were significantly increased and the excitation propagation markedly disordered after MI. SSYX could significantly decrease TAT and the dispersion of TAT, and significantly ameliorate the chaotic spread pattern of excitation. Furthermore, SSYX treatment could significantly decrease COL Ⅰ and COL Ⅲ protein levels and down-regulate TGF-β1 and MMP-2 m RNA expression levels in MI rabbits. It was concluded that SSYX may ameliorate cardiac electrophysiological abnormalities in infarcted hearts by decreasing the protein levels of COL Ⅰ and COL Ⅲ, down-regulating the m RNA expression levels of TGF-β1 and MMP2, and thereby reducing adverse cardiac remodeling.展开更多

In order to more understand the seismic activities in this area, we study the moment tensor solution and the seismogenic structure of the Ruichang-Yangxin earthquake. Precise earthquake relocation shows that the mainshock occurred on the southwestern part of the NE-trending fault and aftershocks are distributed not only along the NE-trending fault but also along its conjugated NW-trending fault. By comprehensive analysis on the earthquake distribution, characteristics of isoseismal curve, focal mechanism, and regional structure characteristics, it is inferred that this earthquake is caused by the NE-trending Tanlu fault. In addition, it has close relationship with the conjugated NW-trending fault as well. Many researches have shown that the junction area is the earthquake-prone area, and should be paid more attention to. And our study also proves this viewpoint.展开更多
