ABSTRACT
Objective:To compare the clinical effects of rivaroxaban and low molecular weight heparin in the treatment of malignant tumor complicated with venous thromboembolism(VTE) in the elderly.Methods:From January 2016 to March 2019, 88 patients with malignant tumor complicated with VTE treated in Zhijiang People's Hospital were divided into observation group and control group according to the random digital table method, with 44 patients in each group.The control group was treated with low molecular weight heparin, while the observation group was treated with rivaroxaban.Each group was treated continuously for 3 months.The therapeutic effect, change of coagulation function and occurrence of adverse events were compared between the two groups.Results:The disease control rate of the observation group[88.64%(39/44)] was higher than that of the control group[84.09%(37/44)], but the difference was not statistically significant( P>0.05). Compared with before treatment, the fibrinogen, D-dimer, prothrombin time and activated partial thromboplastin time in the observation group were (3.22±0.53)g/L, (1.62±0.53)mg/L, (16.35±3.21)s, (39.22±9.03)s, respectively, which in the control group were (3.43±0.59)g/L, (1.73±0.56)mg/L, (15.73±3.24)s, (39.01±9.04)s, respectively, which in the two groups were all improved after treatment (the observation group: t=18.141, 7.243, 11.432, 4.154; the control group: t=15.191, 5.925, 10.357, 4.034, all P<0.05), but there were no statistically significant differences between the two groups(all P>0.05). The incidence of adverse events in the observation group was 9.09%(4/44), which was lower than that in the control group [25.00%(11/44)], the difference between the two groups was statistically significant(χ 2=3.938, P<0.05). Conclusion:Rivaroxaban and low molecular weight heparin in the treatment of malignant tumor complicated with VTE in the elderly has similar effects, which can improve the coagulation function, while the incidence rate of bleeding and recurrence during rivaroxaban treatment is lower and the safety is higher.
ABSTRACT
Objective To investigate the effect of electroacupuncture on acupoint local extracellular ionized atom concentrations under physiological status and provide a basis for exploring the mechanism of action of electroacupuncture. Method Twenty male SD rats were selected. Rat point Zusanli (ST36) was given electroacupuncture (1 mA, 0.2 ms and 2 Hz) for 60 min. Meanwhile, local tissue fluid was collected at point Zusanli and non-acupoints using a microdialyzer. The collection by molecular probe membrane sampling lasted 4 hrs: 60 min physiological status before electroacupuncture, 60 min electroacupuncture, 60 min after electroacupuncture and 120 min after electroacupuncture. Real-time analysis of the sample was made by electrolyte analysis to observe local changes in concentrations of Ca﹢﹢, K﹢, Na﹢and Cl- at point Zusanli. Result Local Ca﹢﹢concentrations at point Zusanli increased significantly during electroacupuncture (P=0.003, vs before electroacupuncture), rose gradually afterwards and reached the peak at 60 min after electroacupuncture (P=0.75, vs during electroacupuncture). Ca﹢﹢concentrations decreased at 120 min after electroacupuncture; there was a statistically significant difference comparedwith during electroacupuncture (P=0.04). Acupoint local extracellular concentrations of Na ﹢ and Cl- also increased significantly during electroacupuncture (P0.05). Conclusion Rat point Zusanli electroacupuncture can induce significant increases in acupoint local extracellular concentrations of Ca﹢﹢, K﹢, Na﹢and Cl- . Ionized atom concentrations decrease in different degrees after electroacupuncture. These provide an experimental basis for studying the physiological mechanism of electroacupuncture treatment.
