Approximately 70％ advanced breast cancer will develop bone metastases.Bone metastases can cause a series of complications such as skeletal-related events,seriously affecting the quality of life of the patients.Therefore,it is very important to choose the reasonable and effective treatments.Bisphosphonates are the standard treatments of bone metastatic breast cancer,denosumab may also be a reasonable alternative to bisphosphonates in the near future,while chemotherapy,endocrinotherapy and targeted therapy are the basic treatments of advanced breast cancer,combined use of various treatments will get the best efficacy.

Objective To investigate whether there is emotional memory advantage bias to negativc emotion facial expressions in stress.Methods A learning-recognition paradigm was used in this study,and 2 groups (stress/non stress)× 3 facial emotional valence (positive/neutral/negative) mixed designs were adopted to compare the reaction time deviations to different facial emotion expressions in stress participants and relaxing participants.Results It was shown by repeated measurement ANOVA that the main effect(E(2.59)=5.13,P=0.007) in facial emotional response time and the interaction effect (F(2.59) =6.02,P=0.003)between groups and facial emotional expression were found.The main effect in recognition of accuracy was observed(F(2.59)=14.47,P=0.000).Further analysis showed,for stress participants,that the reaction time to detect stimulus of positive facial expression ((645.84± 52.65) ms) was faster than negative ((721.46± 101.76) ms) and neutral faces ((692.99 ± 63.17) ms) (P＜0.05) and the recognition of the latter expressions was not significant.Interestingly,the accuracy to recognized of positive facial expression (0.68 ± 0.08) was the highest (P ＜ 0.05) for stress participants.Conclusion Positive faces advantage to facial expression is shown at the stage of face recognition in stress group.

OBJECTIVESTo investigate whether tibial intercondylar hyperplasia can cause anterior cruciate ligament (ACL) injuries.

METHODSFrom February 2009 to October 2012, 58 cases (including 70 knees) with knee osteoarthritis (KOA) without trauma history were selected from the out-patient department of orthopaedics in Guang'anmen Hospital attached to China Academy of Chinese Medical Science. All cases were tested by MRI scanning, then vertical height of the medial and lateral intercondylar spine in coronal position and the area of abnormal signal of ACL in sagittal position were tested from patients. Correlation between the height of intercondylar spine and the area of abnormal signal of ACL were analyzed.

RESULTSFives cases of 58 cases( 70 knees) were excluded from episome in knee joint, and other 65 knees were in accordance with the inclusion criteria. Among them, there were 10 males and 48 females aged from 39 to 79 years old with an average of 61 years old. The vertical height of the medial intercondylar spine was (10.02 +/- 1.46) mm and lateral was (8.92 +/- 1.69) mm. The area of abnormal signal ACL was (318.42 +/- 130.10) mm2. There was positive correlation between the height of medial intercondylar spine and the area of abnormal signal of ACL (r=0.06, P=0.00). But there was no correlation between lateral intercondylar spine and the area of abnormal signal of ACL (P=0.10).

CONCLUSIONThe height of medial intercondylar spine and the area of abnormal signal of ACL is positively correlated. The clinical significance is in study, while the clinical meaning still need further study.

BACKGROUND: Differentiation of neural stem calls (NSCs) was mediated by many environmental factors. Several factors can induce NSCs to differentiate into neurons in varying degrees and it is now a focus on the control of NSCs differentiation.OBJECTIVE: To study the effects of combination of basic fibroblast growth factor (bFGF) and brain-derived neurotrophic growth factor (BDNF) on the differentiation of NSCs into neurons.DESIGN, TIME AND SETTING: The in vitro cytology observation was performed at the Neurotomia Laboratory of China Medical University in May 2008.MATERIALS: Three adult male SD rats were provided by Experimental Animal Center of China Medical University.METHODS: Dispositions to the rats were consistent with ethical standards of animals. The rat brain hippocampus was removed sterilely. After trypsin digestion, NSCs were cultured in serum-free medium. Cell suspension was prepared and diluted when the diameter of the fourth passage of clone sphere was 200 μm by mixture of DMEM/F12 containing 2% B27, 20 μg/L of epidermal growth factor (EGF), and 20 μg/L bFGF. Monoclonal calls were passagad. NSCs were divided into blank control, bFGF, BDNF and bFGF+BDNF groups by different growth factors added into the media. Fetal bovine serum of 0.1 volume fraction was added in blank control group. The media in the other three groups were added bFGF, BDNF and bFGF+BDNF respectively for 1 week.The concentration of bFGF was 10 μg/L and the concentration of BDNF was 200 μg/L.MAIN OUTCOME MEASURES: Immunocytochemistry staining was used to identify NSCs as well as to detect the differentiation of NSCs into neurons.RESULTS: The monoclonal calls expressed nestin and the differentiated call expressed neuron specific enolase and glial fibrillary acidic protein. Compared to blank control group, the proportion NSCs into neurons in the bFGF group, BDNF group and bFGF+BDNF group were much higher (t=3.409-7.558, P < 0.05), with the highest in bFGF+BDNF group (t =7.558, P < 0.05).CONCLUSION: Combination of bFGF and BDNF can promote the differentiation of adult hippocampus NSCs into neurons.
