ABSTRACT
Objective:To evaluate the efficacy and safety of the combination of conventional western medicine therapy and oral traditional Chinese medicine (TCM) compound in the prevention and treatment of radiotherapy-inducedoral mucositis (RTOM) of nasopharyngeal carcinoma patients treated with concurrent radiotherapy and chemotherapy.Methods:A randomized, single-center, and open-label controlled experiment was conducted. Software Stata was used to generate random numbers, and 100 subjects were randomly assigned to two groups ata 1∶1 ratio, namely the integrated Chinese and western medicine group(the integrated group) and the conventional western medicine group. This study focused on the incidence of level-ⅢRTOM, followed by these verity degree of RTOM, therisk of malnutrition, and safety.Results:The incidences of level-III RTOM in the integrated group and the conventional western medicine group were 18% and 46%, respectively, with a statistically significant difference ( χ2=9.007, P=0.003). Compared to the integrated group, the conventional western medicine group showed a significantly increase dseverity degree of RTOM ( OR=3.269, 95% CI: 1.627-6.567, P<0.001) and higher risk of malnutrition ( OR=3.021, 95% CI: 1.786-5.109, P<0.001). Moreover, compared to the integrated group, the conventional western medicine group showed decrease dincidence of thirst (48.97% and 72.00% respectively; χ2=5.493, P=0.019) and decreased incidence of neutrophilcount reduction(12.24% and 30.00%, respectively, χ2=4.668, P=0.031). The incidence of mild/moderate adverse events related to TCM compound was 4.08%(2/49), and no serious adverse events related to TCM compound were observed. Conclusions:Compared to the conventional western medicine regimen, the integrated Chinese and western medicine regimen IS more effective in the prevention and treatment of RTOM. Meanwhile, its clinical application is safe and reliable.
ABSTRACT
Objective To investigate the effective therapic methods of the perioperative vasovagal reflex(RV)in patients with atrial arrhythmias(AAs)underwent by catheter ablation .Methods The clinical data in the patients with atrial arrhythmias(AAs) complicated by vasovagal reflex(RV)were retrospectively analyzed during the perioperative procedure of catheter ablation guided by three dimensional mapping system CARTO ;the clinical data were compared between patients with RV and without RV .Results A total of 535 patients with AAs underwent catheter ablation guided by three dimensional mapping system were collected from Janu‐ary 2010 to December 2012 ,and 35 cases of intraoperative RV were found .Compared by patients without RV ,the patients with RV had more elderly cases and the cases of hypertension ,coronary heart disease and diabetes .The RV occurrence was also associated with the fasting ,painful stimuli ,operation time and skill .Conclusion The perioperative RV often is occurred in the cases of high risk and have the precipitating factors ,and the good prognosis could be obtained by the detect and treatment as early as possible .
ABSTRACT
Objective To investigate the efficacy and safety of radiofrequency catheter ablation for treating epicardial accessory pathway .Methods 8 patients with unsuccessful endocardial ablation of accessory pathway were mapped within coronary venous si-nus or middle cardiac vein and the radiofrequency catheter ablation was performed by the temperature control electrode .Results Ablation in 8 cases was successfully performed within coronary sinus or middle cardiac vein .There were no complications in all pa-tients .Conclusion Radiofrequency catheter ablation of epicardial accessory pathway within coronary sinus and middle cardiac vein is safe and effective .
ABSTRACT
Objective:To study the expression of Fas and FasL in hyperthyroid cardiopathy and to explore its possible effect and clinical significance in the pathogenesis of the hyperthyroid cardiopathy.Methods:Twenty New Zealand rabbits were randomly divided into two groups: control group(n =10) and experimental group(n =10).Hyperthyroidism animal model was established by peritoneal injection of Levothyroxine(L-Thy) in experimental group.All the rabbits were followed up for 4 weeks.Every 7 days blood samples were obtained.Serum TT3 and TT4 were measured with radioimmunoassays(RIAs).Electrocardiogram(ECG) was performed to determine heart rate(HR).All the rabbits underwent echocardiography and the thickness of IVS?LV?LA?LVPW and LVEF were measured at the end of the follow-up period.Ventricular tissues were collected at 4th weeks.Cardiac hypertrophy index,cardiomyocyte diameter,structural change were detected.Cardiac fibrosis was displayed by Masson stain and collagen volume fraction(CVF)was measured using pathological image analytic system.Protein of Fas and FasL were localized by immunohistochemistry and semi-quantified with pathological image analytic system.Results: In experimental group,the thickness of IVS?LV?LA?LVPW,cardiac quality index,cardiomyocyte diameter,collagen volume fraction(CVF) and the expression of Fas in left atrium and left ventricle increased obviously(P
