Objective To examine the expression of angiopoietin-2(Ang-2) in squamous carcinoma of esophagus,and discuss the relationship between Ang-2 and microvessel density(MVD)and clinical pathological features of squamous carcinoma of esophagus.Method The expression of Ang-2 and CD34 in 80 squamous careinoma of esophagus and 25 normal esophagus were detected by immunohistochemistry SABC technique,and the MVD of tissues signed by CD34 was counted.Results The expression of Ang-2 in squamous carcinoma of esophagus was,higher than that in normal esophagus (P<0.05).The expression of Ang-2 in the stage O-I and II squamous carcinoma of esophagus was lower than that in stage Ⅲ and lV(P<0.05).The expression of Ang-2 in squamous carcinoma of esophagus was correlated with differentiation of esophageal carcinoma and lymph node metastasis and infiltrative deepness.There was a remarkable posidve correlation between the expression of Ang-2 and MVD in squamous carcinoma of esophagus (r=0.603,P<0.05). Conclusion The expression of Ang-2 may be elated to the development of squamous carcinoma of esopha- gus,and may promote the development of squamous carcinoma of esophagus by promoting angiogenesis in tumor.

Objective To evaluate the effect of self-management interventions on the quality of life of patients with heart failure(HF).Methods The randomized controlled trials(RCTs)taking self-management interventions were collected from the databases of EMBASE,Medline,VIP,CNKI and WanFang.Data were analyzed with RevMan 5.1 software.Results 12 articles met the inclusion criteria.There was considerable heterogeneity across the analysis,which might be result from length of intervention,age and NYHA classification according to subgroup analysis.Self-management interventions could significantly improve the quality of life of patients with HF,including both physical and emotional aspects.Conclusions Self-management interventions can improve the quality of life of patients with heart failure.
