Objective To assess the effectiveness and safety of various types of acupuncture in the treatment of mammary dysplasia. Methods We searched The Cochrane Library, CENTRAL, MEDLINE (1966 to 2004), EMBASE (1980 to 2004), CBM (1975 to 2004), CNKI (1997 to 2004) and reference lists, databases of ongoing trials and relevent academic conference proceedings. Results Five studies involving 534 women ranging from 78 to 180 met the inclusion criteria. The recovery rates of two groups in one study showed acupuncture was statistically superior to Rupixiao (RR 9.00, 95%CI 2.29 to 35.43; RR 8.04, 95%CI 2.20 to 32.02), six good improvement rates (including groups analysis) indicated that there was no significant difference between acupuncture and other therapies. None of the studies reported incidence of adverse reaction. Conclusions Overall, there is no conclusive evidence for acupuncture in the treatment of mammary dysplasia because the quality of included studies and amount of evidence are both poor and insufficient. There is an urgent need for larger, well-designed randomised controlled trials to assess the effectiveness and adverse-effect of acupuncture.
ObjectiveTo investigate the relationship between the polymorphisms of estrogen receptor α (ERα) gene PvuⅡ, XbaⅠ and breast hyperplasia. MethodsPolymerase chain reaction-restriction fragment length polymorphism was used to detect the polymorphisms of ERα gene PvuⅡ, XbaⅠ in breast hyperplasia patients (study group, n=89) and healthy controls (control group, n=35). ResultsThe differences of the genotypic frequency and allele frequency of the ERα gene Xba Ⅰ were significant between the study group and the control group (Plt;0.05). According to analysis of the odds ratio (OR), the risk of developing breast hyperplasia for X allele carriers was 0.551 as compared with x allele carriers. But there was no significant difference for the gene polymorphism of PvuⅡ between the study group and the control group (Pgt;0.05). ConclusionThe polymorphisms of XbaⅠof ERα gene is associated with breast hyperplasia and the mutant gene increases breast hyperplasia risk.
The sonographic features of male breast lesions, which underwent ultrasound examination in our hospital for the past 10 years, were retrospectively analyzed. Sonographic features of these lesions were standardized as BI-RADS image lexicon. The differences in ultrasonic malignant signs were assessed between the benign and the malignant diseases. Between the two groups, incomplete boundary was statistically different. The specificity was above 95% within the two groups in terms of speculated margin, echogenic halo, calcification, axillary lymphadenopathy, thickening of skin and eccentric of mass to the nipple. High-frequency sonographic examination has a high level of differential diagnosis for male breast lesions.
