Background: This study assessed the differences in femoral geometry and bone mineral density between femoral neck fragility fractures and trochanteric fractures. Methods: One hundred and seventeen patients were divided into femoral neck and trochanteric fracture groups. There were 69 patients with femoral neck fractures, 20 men and 49 women with an average age of 75.1 ± 9.6 years and an average body mass index (BMI) value of 21.6 ± 4.1 kg/m

Background: Full-field digital mammography (FFDM) with dense breasts has a high rate of missed diagnosis, and digital breast tomosynthesis (DBT) could reduce organization overlapping and provide more reliable images for BI-RADS classification. This study aims to explore application of COMBO (FFDM+DBT) for effect and significance of BI-RADS classification of breast cancer. Materials and Methods: In this study, we selected 832 patients who had been treated from May 2013 to November 2013. Classify FFDM and COMBO examination according to BI-RADS separately and compare the differences for glands in the image of the same patient in judgment, mass characteristics display and indirect signs. Employ Paired Wilcoxon rank sum test was used in 79 breast cancer patients to find differences between two examine methods. Results: The results indicated that COMBO pattern is able to observe more details in distribution of glands when estimating content. Paired Wilcoxon rank sum test showed that overall classification level of COMBO is higher significantly compared to FFDM to BI-RADS diagnosis and classification of breast (P<0.05). The area under FFDM ROC curve is 0.805, while that is 0.941 in COMBO pattern. COMBO shows relation of mass with the surrounding tissues, the calcification in the mass, and multiple foci clearly in breast cancer tissues. The optimal sensitivity of cut-off value in COMBO pattern is 82.9%, which is higher than that in FFDM (60%). They share the same specificity which is both 93.2%. Conclusions: Digital Breast Tomosynthesis (DBT) could be used for the BI-RADS classification in breast cancer in clinical.

In recent years, with increasing prevalence, particularly in young patients, breast cancer is considered to be one of the most common malignancies. The aim of the present study was to evaluate the clinical value of digital breast tomosynthesis (DBT) in diagnosing molecular subtypes of breast cancer. The present study retrospectively analyzed 134 cases of breast cancer with data regarding surgery, complete pathology and immunohistochemistry, which were collected at The Second Clinical College of Fujian Medical University (Quanzhou, China) between May 2013 and October 2014. The patients were divided into the four following molecular subtypes: Luminal A, luminal B, triple-negative and human epidermal growth factor receptor 2 (HER-2) overexpression, according to the expression of estrogen receptor, progesterone hormone receptor, HER-2 and Ki67. The association between clinical characteristics of each molecular subtype and characteristics of DBT were assessed. Calcification scores and lymph node size were the indicators that exhibited a significant difference following comparison between the four molecular subtypes. The subgroup analysis based on tumor size, calcification scores and lymph node size identified a significant difference in the distribution between patients with breast cancer with lymph node size of ≥1.5 and <1.5 cm. The analysis also revealed that the molecular subtypes of breast cancer were significantly associated with variables of calcification scores and lymph node size. In conclusion, the diagnostic imaging features, including calcification score and lymph node size, determined using DBT could be used as assistant diagnostic markers of breast cancer molecular subtypes.

Extrahepatic or intrahepatic bile duct stenosis and obstruction can lead to malignant obstructive jaundice (MOJ). Surgical treatment is an effective method, but for patients who cannot undergo surgery or miss the opportunity for surgery, biliary stent combined with 125I implantation can improve obstruction symptoms, relieve biliary obstruction, and improve liver function. This study was to investigate the efficacy of 125I implantation, single biliary stent and percutaneous transhepatic drainage (PTCD) in the treatment of MOJ. 107 patients with MOJ were included. Thirty-seven patients (study group) received biliary stent implantation of 125I particle radiotherapy drainage tube, and 35 patients (sem group) received biliary stent implantation of ordinary drainage tube. 35 patients (PTCD group) underwent PTCD interventional surgery. Biliary stenosis site, Child-Pugh grade and malignant tumor were recorded in the three groups. The changes of liver function before and after treatment were detected, and the survival time, stent patency time, and the occurrence of complications were recorded. All three groups achieved technical success. Liver function was improved in all patients (TBIL, DBIL and ALT were significantly decreased, and P values were all less than 0.05). This study demonstrates that 125I seed beam implantation combined with biliary stent implantation can be considered a safe treatment option for patients with MOJ. This treatment can improve median overall survival, improve liver function, prolong stent patency time.
