To introduce the application of Stata software to heterogeneity test in meta-analysis.A data set was set up according to the example in the study,and the corresponding commands of the methods in Stata 9 software were applied to test the example.The methods used were Q-test and Ⅰ2statistic attached to the fixed effect model forest plot,H statistic and Galbraith plot.The existence of the heterogeneity among studies could he detected hy Q-test and H statistic and the degree of the heterogeneity could be detected by,Ⅰ2 statistic.The outliers which were the sources of the heterogeneity could be spotted from the Galbraith plot.Heterogeneity test in Meta-analysis can be completed by the four methods in Stata software simply and quickly.H and Ⅰ2 statistics are more robust,and the outliers of the heterogeneity can be clearly seen in the Galbraith plot among the four methods.

Objective To explore the effects of nursing intervention on the compliance of family oxygen therapy of COPD patients in stable phase. Methods Totals of 56 patients with COPD patients were investigated with the self-designed questionnaire .Analyzed related factors of family oxygen compliance, and gave the nursing. intervention including propaganda on disease knowledge ,nursing and guidance about oxygen inhalation ,interventions of psychnological and family support .Then ,observed the compliance of family oxygen therapy after six months.
