ABSTRACT
Objective To observe the protective effects with vascular endothelium of Danhong injection for unstable angina (UA)after percutaneous coronary intervention in patients.Methods 180 patients with UA were ran-domly divided into two groups,and patients undergoing percutaneous coronary intervention (PCI)therapy.In addi-tion,90 cases in the control group were treated with conventional western medicine treatment,90 cases in the observa-tion group were treated with conventional western medicine treatment and Danhong injection therapy.The serum super-oxide dismutase (SOD),malondialdehyde (MDA)and brachial artery flow -mediated endothelium -dependent vaso-dilation (FMD),von Willebrand factor (vWF),plasma nitric oxide (NO),endothelin -1 (ET -1)levels and other indicators before and after treatment were detected.Results The total effective rate of the observation group was 96.67%,which was significantly higher than 75.56% of the control group (χ2 =9.23,P <0.05).The endothelial function parameters NO(73.66 ±11.58)μmol/L,ET -1 (64.75 ±6.83)ng/L,vWF(114.58 ±16.24)%,FMD (6.54 ±0.88)% of the observation group after treatment were significantly improved than before treatment (t =8.04,7.90,8.44,7.67,all P <0.05),which of the control group were (62.78 ±10.42)μmol/L,(92.31 ±8.67)ng/L, (152.64 ±18.75)%,(4.18 ±0.72)%,there were significant differences(t =6.78,7.34,7.70,6.56,all P <0.05).The serum SOD (154.62 ±21.37)U /mL and MDA (4.18 ±0.79)nmol/L levels of the observation group were significantly improved than before treatment(t =7.58,8.67,all P <0.05 ),which of the control group were (132.45 ±26.89)U /mL,(5.27 ±1.16)nmol/L,there were significant differences (t =7.22,7.81,all P <0.05). Conclusion Danhong injection for the treatment of UA stasis syndrome can be widely promoted by reducing oxidative stress on vascular endothelial damage,and improving endothelial function in patients after PCI,has great clinical value.
ABSTRACT
Objective:To observe the effects of real-time and retrospective analyze of cardiac remote monitoring based on differential threshold method.Methods: Xin An Bao XAB - M3AG ECG remote monitoring system which based on the differential threshold method of improvement being used to determine the parameters of electro cardio signal was installed in 8957 patients.Results: We had collected all 46967 ECG real-time data, including 9564 manual transmission, 25830 timing transmitting and 11573 automatically transmission. 5728 of automatically transmission was with arrhythmia (49.5%) and the others of automatically transmission was attribute to inference.Conclusion: The results showed that algorithm complexity based on the improved differential threshold method is low, the precision is high and it has a good real-time performance. It realized the real-time monitoring of ECG.
