ObjectiveUsing the single cell fluid to establish a kind of practical experimental method,to detect the HER-2 gene and protein of breast cancer,and to provide reliable basis for pathology diagnosis.MethodsThe single cell fluid of breast cancer was preparaed by Medimachine system.Sucking a little of the single cell fluid spreaded on the slide and to be examined by immunohistochemistry using antibodies to HER-2 and fluorescence in situ hybridization.ResultsThe cell membrane of breast cancer was positive for HER-2 by immunohistochemistry according to American society of clinical oncology of American pathologists guideline recommendations for HER-2 testing in breast cancer and the HER-2 gene of the single cell amplified obviously by fluorescence in situ hybridization which the ratio of the average of HER-2 and the average of CEP17 exceeded 2.2.ConclusionThe single cell fluid could be used as positive control when we detected the HER-2 gene or protein of breast cancer,which guaranteed the correction of the results of the sample to be detected.

Anti-endothelial cell antibodies (AECA) are heterogeneous autoimmune antibodies, which target at a group of antigens expressed in endothelial cells. In 1971, AECA was reported by Lindquist and Osterland for the first time. Since then, an increasing number of researches have showed that AECA exists and plays potential pathogenic role in the immune or inlfammation-related diseases, especially in systemic vasculitis. AECA may be a useful sera marker for the diagnosis and prognosis judgment of related autoimmune diseases. In this review, we summarize the recent progress on the relationship between AECA and systemic vasculitis.

Microglia can be activated immediately after acute cerebral ischemia and play a role of double-edged sword of nerve repair and neurotoxicity.Studies in recent years have suggested that this dual role of microglia can be achieved by a Toll-like receptor 2 (TLR2) signal transduction pathway.Therefore,reasonable regulation of TLR2 expression of microglia may improve the therapeutic effect of cerebral ischemia to a certain extent.This article reviews the mechanisms of TLR2 in cerebral ischemia and the possible interventions.

Objective:To explore dynamic change of heart rate variability (HRV) before and after circumferential pulmonary vein ablation (CPVA ) in patients with paroxysmal atrial fibrillation (PAF) and its relationship with postoperative recur‐rence .Methods:A total of 108 PAF patients undergoing left atrial circumferential pulmonary vein electrically isolated ra‐diofrequency ablation were selected .According to 12‐lead DCG on 3d and three months after operation ,patients were di‐vided into early recurrence group (n=10) ,late recurrence group (n=21) and no recurrence group (n=77) .HRV changes were followed up and compared among all groups .Results:Compared with before ablation ,on 3d after ablation ,there were significant reductions in standard deviation of normal to normal RR intervals calculated over the 24 h period (SDNN) , standard deviation of normal to normal RR intervals in all 5 min segments of the entire recording (SDANN) ,root‐mean square of differences betweensuccessive normal to normal intervals (rMSSD) ,low frequency (LF) ,high frequency (HF) in no recurrence group ;significant rise in mean heart rate ,and significant reductions in SDNN ,LF and LF/HF in early recur‐rence group ( P< 0.05 or <0.01);compared with no recurrence group ,there were significant rise in mean heart rate [(69.3 ± 11.2) beats/min vs .(75.4 ± 14.0) beats/min] ,SDANN[(66.9 ± 25.7)ms vs .(137.5 ± 92.3)ms] ,rMSSD [(22.1 ± 10.6)ms vs .(46.2 ± 19.2)ms] ,LF [(233.1 ± 31.4)ms vs .(251.7 ± 17.3)]and HF[(228.0 ± 82.4) ms2 vs .

Objective To discuss the practical application effect of the work process oriented teaching model that based on flipped classroom in the teaching of higher vocational Chinese medicines.Method We chose 97 students from Grade 2012 higher vocational Chinese traditional medicine,set them into experimental group (47 students) and comparison group (50 students).The experimental group was applied with the flipped classroom teaching,combined with the teaching mode of working process and the comparison group was applied with the traditional teaching mode from September 2014 to July 2015.At the end of the experiment,through the questionnaire survey,the differences of the experimental group students' autonomous learning ability and problem solving ability were compared between before the experiment teaching and after the teaching.The difference of post adaptation ability of the experimental group and the control group was also compared,and besides,the students' satisfaction degree to flipped classroom combined with working process teaching mode was investigated and analyzed.SPSS 16.0 software was used for statistical analysis,and t test was used to compare two groups' measurement information and count data with chi-square test.Result The score of independent learning ability after teaching in the experimental group was significantly higher than before [(77.50 ± 7.10) vs.(88.51 ± 9.30);t=6.451,P=0.000].However,there was no statistically significant difference in problem-solving capability before and after the teaching[(83.70 ± 2.32) vs.(84.30 ± 2.11);t=1.312,P=0.193].The score of five aspects of the adaptability to work in the experimental group and total score were higher than the comparison group and the difference was statistically significant [work attitude (18.72 ± 2.01) vs.(16.78 ± 3.33),t=3.447,P=0.001;service ability (17.99 ± 1.98) vs.(16.05 ± 2.15),t=4.614,P=0.000;professional ability (18.19 ± 2.46) vs.(15.37 ± 2.79),t=5.267,P=0.000;completion of work (19.01 ± 1.75) vs.(16.88 ± 1.83),t=5.851,P=0.000;strain capacity:(18.33 ± 2.09) vs.(17.01 ± 2.46),t=2.839,P=0.006;the total score of job adaptability (92.24 ± 3.89) vs.(82.09 ± 4.05),t=12.574,P=0.000].Experimental group's satisfaction showed that 91.48％ of students liked the teaching model,87.23％ thought that it improved their learning interest,82.98％ believed that it was beneficial to improving their communication skills.Conclusion Teaching mode of flipped classroom combined with working process helps to improve teaching quality.

Carcinoma of pancreas is the most common primar y pancreatic malignancy. Symptoms usually are nonspecific and include abdominal pain, jaundice, loss of appetite, weight loss, nausea, and vomiting. CT usually demonstrates a mass with ill-defined margins but also solid components and dil atation of the main pancreatic duct. This tumor is usually smaller and virtuall y never contains calcification. Following contrast material administration,all masses were enhanced less than the surrounding pancreas. Tumors were oval, rou nd or lobular,and is almost always locally invasive. These features can be used to differentiate carcinoma of pancreas from other pancreatic tumors.
