Objective To investigate the effects of Gegenqinlian decoction combined with berberine in the treatment of biguanides resistant type 2 diabetes in elderly patients in glycosylated hemoglobin and homocysteine.Methods 82 elderly patients from March 2015 to March 2016 in our hospital who were diagnosed with type 2 diabetes with biguanides resistant were selected,and randomly divided into two groups,41 cases in each groups.Control group receiced routine treatment,experimental group received more with Gegenqinlian Decoction combined with berberine treatment,and all the patients were treated for two weeks.Levels of FPG,2h PG,serum HbA1c,Hcy,hs-CRP,APN,TNF-α,ICAM-1 and clinical efficacy were compared,and the results were analyzed by statistical software SPSS 19 data analysis.ResultsCompared with before treatment,levels of serum FPG,2h PG,HbA1c,Hcy,hs-CRP,TNF-α and ICAM-1decreased in two groups after the treatment(P<0.05),levels of AFN increased(P<0.05),Compared with the control group,levels of serum FPG,2hPG,HbA1c,Hcy,hs-CRP,TNF-α and ICAM-1 in the experiment group were lower(P<0.05),levels of AFN were higher(P<0.05);The total effective rate of the experimental group was significantly higher than the control group(P<0.05).Conclusion Gegenqinlian decoction combined with berberine can effectively reduce the levels of FPG,2h PG,HbA1c,Hcy,hs-CRP,TNF-α in serum and ICAM-1 levels,increase serum APN level,and good curative effect,worthy of clinical application and promotion.
