Objective To investigate the mammographic,galactographic,pneumographic features and their pathological basis.Methods Mammography(n=26),galactography(n=13),pneumography(n=5)and specimen radiography(n=12) in 26 cases pathologically proved,and mammographic-pathologic correlation were analyzed.Results The breast hamartomas in 26 cases were all benign,they were circumscribed and surrounded by a true capsule.The mammographic appearances could be divided into three types acording to different amount of fibroglandular and adipose tissue in tumors:prominantly fatty,prominantly fibrous(fibroglandular)and mixed fibrofatty.Conclusion A clearly containing areas of fat and fibroglandular density and a characteristic"slice of sausage"appearance can be showed on mammograms.Galactography and pneumography is of a great help to differential diagnosis of breast hamartomas.

Objective To investigate the level and influencing factors of falls efficacy among older patients with type 2 diabetes (T2DM) .Methods A total of 218 older patients with T2DM were investigated by the modified falls efficacy scale(MFES) and Morse Fall Scale (MFS) ,questionnaire and observation were both used .Results The average score of falls efficacy was 8 .15 ± 2 .91 .The scores were lowest in the items of walking up and down stairs and going to bed and getting out of bed ,and highest were in the items of dressing and sitting down and standing up from a chair .The multivariate linear regression analysis showed that dura‐tion of diabetes ,diabetic complications and fall history were the main factors influencing their falls efficacy .Conclusion Falls in eld‐erly T2DM patients were in the medium level ,and it′s closely related with duration of diabetes ,its complications and fall history .
