Materials and Methods:236 pathology-confirmed breast lesions(155 malignanty,81 benignancy) and 221 disease-free contralateral breast tissues were examined using EPI-DWIb values=0,1000 s/mm~2TR/TE=8400ms/93.8ms; FOV=30×30cm;matrix=128×128;ASSET=2,slice thickness=4mm.DCE-MR imaging was also performed for accurate location of the lesion using VIBRANT sequence.The mean ADC values of malignant and benign lesions and the disease-flee contralateral breast tissues were calculated from the ADC map for each patient.One-way analysis of variance was applied to compare the mean ADCs of malignant lesions with benign lesions and disease-flee contralateral breast tissues.The threshold ADC value for malignant lesion was determined using a receiver operating characteristic(ROC curve analysis.Each lesion was classified into two major types:mass and non-mass lesion.The diagnostic performance of DWI was compared in breast mass and non-mass lesions.Results:155 malignant and 81 benign lesions were confirmed in 236 lesions.

The result showed:leptin level was positive related with the level of E2,P in mammary only duringthe pregnancy,leptin level was positive to the level of Prl GH during the pregnancy-lactation cycle Hint:leptin in mammary might promote the development of mammary duct and gland bubble with E2,P;leptin in mammary might promote the mammary development and start secretion of milk with Prl; leptin in mammary and GH were promoting the growth during mammary developmen,strengthen the action to promote the gland bubble development with Prl,mighe play an important role in the modulation of the mammary gland development.
