ABSTRACT
Objective To investigate the clinical effect of radiofrequency ablation (RF) combined with digital subtraction angiography (DSA)-guided percutaneous ethanol injection sclerotherapy in the management of high-return flow venous malformation (VM).Methods Forty-one patients,who were diagnosed as high-return flow VM with clinical and radiographic evidence,were divided into the observation group (n=19) and the control group (n=22) using a random number table.All high-return flow VM patients received DSA-guided percutaneous ethanol injection sclerotherapy while the patients in observation group were given radiofrequency ablation.The clinical effect,treatment times and adverse effect of the two groups were analyzed.Results The effectiveness of the observation group was significantly higher than those of the control group [94.7％ (18/19) vs 81.8％ (18/22)].The facial paralysis occurred in three patients (13.6％) after ethanol injection in the control group,while the observation group had no facial nerve injury after treatment.The patients in observation group had significantly fewer numbers of ethanol injection.Conclusions RF can improve the efficacy of high-return flow VM and reduce the number of ethanol injection.The scheme is safe and effective.
ABSTRACT
Myocardial ischemia/reperfusion(MI/R) injury refers to restoring blood perfusion after myocardial ischemia for a relatively long time, but the tissue appears more obvious and severe myocardial damage and dysfunction than before reperfusion, this phenomenon mainly relates to inflammation, oxidative stress, cell apoptosis, cell autophagy and so on.NF-κB is a nuclear transcription factor involved in regulating a variety of pathophysiological processes, which also plays an important role in all aspects of MI/R injury.The in-depth study of NF-κB in MI/R injury and clinical application of related research will provide new ideas and methods for treating MI/R injury.
ABSTRACT
Objective To investigate the prevalence of gastroeaophageat reflux disease(GERD)in the end stage renal disease patients(ESRD)with maintenance hemodialysis and the pathogenetic factors of GERD.Methods 60 cases who had heart burn and acid regurgitation symptoms were enrolled,31 cases of them were ESRD patients with maintenance hemodialysis,29 patients who were renal diseases free as control group.GERD was diagnosed by three methods:endoscopy,24h esophageal pH monitoring,endoscopic esophageal biopsy.GERD was established if any of these tests was positive.HP infection and serum gastrin were assessed too.Results (1)The prevalences of GERD in two groups were 83.9%,79.3% respectively and had no significant difference(P＞0.05).(2)The prevalence of HP infection in the ESRD group was significantly lower than control group(19 4% vs 51.7%,P＜0.05).(3)The concentration of serum gastrin in the ESRD group and control group was(102.61±30.80)ng/ml and (83.41±20.61)ng/ml,two group had significant difference(P＜0.05).Conclusion The prevalence of GERD inthe ESRD patients was higher than expected,and was correlated with absence of HP infection and hypergastinemia.
