Objective To analyze the mammographic features of invasive lobular carcinoma (ILC)compared to those of invasive ductal carcinoma (IDC).Methods Twenty cases with ILC and 95 cases with IDC were retrospectively evaluated by two breast radi-ologists according to the Breast Imaging Reporting and Data System (BI-RADS)lexicon.The mammographic findings were com-pared between ILC and IDC with the independent samples chi-square test or Fisher’s exact test,as appropriate.Results Mass was the most common finding in both ILCs and IDCs,but less frequent in ILCs (36.4% vs 63.9%,P =0.008).Mass in ILCs was more frequently lobular or irregular shape with spiculated margin.Architectural distortion and focal asymmetry were more frequent in ILCs than in IDCs,however,the differences were no significant.The frequency of calcifications was not significantly different between the two groups.The distributions of calcifications were more regional in ILCs,and more segmental or linear in IDCs (P =0.01).Conclu-sion ILCs are more usually shown as non-mass appearances on mammography.ILCs that appeared as mass are more frequently ir-regular in shape with spiculated margins.

OBJECTIVE To explore the effect of connexin (Cx) 40-formed gap junctional intercellular communication (GJIC) on Photofrin- photodynamic therapy (PDT) phototoxicity in Cx40- transfected HeLa cells and its potential mechanisms. METHODS HeLa cell line stably transfected to express Cx40 was seeded at high and low cell density, respectively, to assess in vitro photosensitivity using CCK8 assay. Western blot assay was performed to detect the expression of Cx40. The intracellular ROS and Ca2 +concentrations were determined using flow cytometer. 4-HNE and ceramide were measured using ELISA assay. RESULTS Cx40-composed GJ formation at high density enhances the phototoxicity of Photofrin-PDT. When the Cx40 is not expressed or Cx40 channels are blocked, the phototoxicity in high-density cultures substantially reduces, indicating that the enhanced PDT phototoxicity at high density is mediated by Cx40-composed GJIC. The GJIC-mediated increase in PDT phototoxicity was associated with ROS and calcium-mediated stress signaling pathways. CONCLUSION The work uniquely presents the ability of Cx40-composed GJIC to enhance the sensitivity of malignant cells to PDT, and indicates that mainte?nance or increase of Cx40-formed GJIC may be a profitable strategy towards the enhancement of PDT therapeutic efficiency.

Yunnan sudden death syndrome (YSDS) is an abruptly fatal disease of unknown etiology, found mostly in central or northwestern mountain area (with altitude between 1,815 and 2,225 meters) of Yunnan province from June to September every year. It occurs mostly in young female adults, with high incidences in Lisu, Yi and Miao ethnics and high familial aggregation. The clinical manifestation of YSDS is changeful and the pathological characteristic is lack of specificity. The pathogenesis may be attributed to several factors including poor hygiene and lower socioeconomic conditions, lack of Selenium or Chromium, infection of Coxsackie B virus, mushroom consumption and special geological conditions. This article reviews the epidemiologic features, clinical manifestations, pathological features, etiology and hypothesis in order to provide clues for the research of YSDS.

Lysostaphin is highly effective on eliminating methicillin resistant Staphylococcus aureus (MRSA). In order to achieve controlled release of lysostaphin, a biocompatible drug carrier is needed. Hydroxyapatite/chitosan (HA/CS) composites were chosen to carry lysostaphin and sample composites with different weight ratios of HA to CS, including 80/20, 70/30, 60/40, and 40/60, were prepared. Multiple analyses were performed to determine the structural and physicochemical properties of the composites, including scanning electron microscopy, X-ray diffraction and Fourier transform infrared spectroscopy. We immersed HA/CS composites loaded with 1 wt% lysostaphin to test in vitro release activity and cultured MC3T3-E1 cells to carry out biocompatibility test. The result of the release behavior of the composites revealed that the controlled release of lysostaphin from 60/40 HA/CS composites was the highest release rate of (87.4 ± 2.8)%, which lasted for 120 hours. In biocompatibility testing, MC3T3-E1 cells were able to proliferate on the surface of these composites, and the extract liquid from the composites could increase the growth of the cells. These results demonstrate the controlled release of lysostaphin from HA/CS composites and their biocompatibility, suggesting the potential application of these composites to bone injury and infection applications.
