Objective To investigate the pathologic base of breast cancer malignant halo.Methods The status of margin of 80 cases confirmed breast nonspecific invasive ductal cancer by pathology were determined preoperatively.80 cases were divided into two groups:malignant halo group and non malignant halo group.The estrogen receptor (ER),progesterone receptor (PR),human endothelial growth factor receptor (CerB-2),nuclear protein antibodies (Ki-67) expression were detected by immunohistochemical method.The histological grade,mitotic count and documented tumor size,patient age and the number of lymph node metastases,breast cancer margin on pathology were observed.Halo tissue were drawn from specimens and the tissue structure were observed.Results Ki-67 expression in malignant halo group were significantly lower than those in non malignant halo group.The observing results of the margin status of breast cancer on ultrasound and pathology were consistent.Halo tissue was mainly composed of fatty tissue and scattered clumps of cancerous tissue,fibrous tissue,normal lobular and tubular.Conclusions Malignant halo is a special manifestation of breast cancer on gray-scale ultrasound.

Objectives: To explore the role of liver in the process of severe acute pancreatitis. Methods:Comparing the survival time, the endotoxin level of plasma and ascites , the IL-6 level of serum and ascites, the platelet granule membrane protein-140 (GMP-140) level of plasma and the histology change of lung between control group, portocaval shunting group(PC), acute necrotic pancreatitis (ANP) group and acute necrotic pancreatitis immediately after portocaval shunt(PC+ANP) group of rats. Measuring the serum IL-6 of control group, portocaval shunt control group (injecting normal saline through caval vein, PCJ), ascites injecting group (AJ) and ascites injecting portocaval shunt group (PC+AJ). Results: The survival time of PC+ANP group was much shorter than those of the other groups, and its plasma endotoxin , serum IL-6 and plasma GMP-140 levels were higher than those of the other groups (P

Objective To study the clinical and pathologic features, diagnosis, treatment and prognosis of splenic marginal zone lymphoma (SMZL). Methods We reported the detailed clinical and pathologic presentation of a patient with SMZL, and monitored fellow-up to 16 years. Results Patients present with splenomegaly. SMZL usually involve bone marrow, peripheral blood and hilar splenic lympha nodes. Peripheral lymph nodes and nonhematolymphoid organs can be involved as well, but to a lesser extent.Microscopically, tumor cells are small to medium in size, with dispersed chromation. Tumor cells are slgM(+),CD+20, CD+79a,, bcl-2(+), CD-3, CD-5, CD-10, CD-23 and CyclinDl(-). Conclusion SMZL is a rare low-grade B-cell lymphoma with an indolent clinical course. Spleneetomy and chemotherapy are effective treatment but SMZL cannot be completely cured and may transform to large B-cell lymphoma at last.

Objective To investigate the effect of astragalus polysaccharides injection (APS) on autophagy of human nasopharyngeal cancer CNE-2 cells.Methods The inhibitory effect of APS on proliferation of CNE-2 cells was measured by CCK8 assay.Morphological changes of autophagy of APS was detected by acridine orange (AO) staining.Transmission electron microscopy was perform to observe the morphological alterations in the autophagic cells.The expression of Beclin-1 protein was detected by Western blot assay.Results APS markedly inhibited cell growth in a dose-and time-dependent manner.Increases of the number of large vacuoles and double layered membrane structure were observed by transmission electron microscopy.Results of AO staining revealed more bright red cytoplasm or nucleus in the ceradime group,which proved the existence of acidic vesicular organelles.Western blotting showed that Beclin-1 protein level was up-regulated.Conclusion APS may induce autophagy of human nasopharyngeal cancer CNE-2 cells via up-regulating the expression of apoptosis-related gene of beclin1 and inhibit the proliferation of CNE-2 cells.

According to the constructivism approach, instructors have to adapt to the role of fa-cilitators but not teachers. Whereas a teacher gives a didactic lecture that covers the subject matter , a fa-cilitator helps the learner to get to his or her own understanding of the content. In the former scenario the learner plays a passive role and in the latter scenario the learner plays an active role in the learning pro-cess. Under the guidance of this theory, a multi-dimension teaching model based on classroom teaching, network platform and innovate experiments has been established in the course of basis of clinical labora-tory. It has been found that this model is conducive to raising students' interests in learning and to culti-vating student's comprehensive quality.

Objective:To investigate the association patterns of chronic disease-relevant risk factors for the adults in Haidian District.Methods:Data for chronic disease-relevant risk factors for 3 219 adults in Haidian District in 2014 were collected and analyzed.SPSS 18.0 was used for statistical description and logistic regression.SPSS Modeler 14.1 was used to explore the association among the chronic disease-relevant risk factors.Results:Among men,5 patterns of chronic disease-relevant risk factors were identified,which suggested that heavy drinking,inadequate intake of fruit and vegetables,and physical inactivity were associated with smoking while inadequate intake of fruit and vegetables and smoking were associated with physical inactivity.Among women,one pattern of chronic disease-relevant risk factor was identified,which suggested that inadequate intake of fruit and vegetables was associated with physical inactivity.Conclusion:Chronic disease-relevant risk factors are intercorrelated among the adults in Haidian District.Information on patterns of chronic disease-relevant risk factors could assist interventions targeting multiple behaviors simultaneously.

The relationship of nutrients and microorganisms in soils with polyphenols and total flavonoids of Houttuynia cordata were investigated by measuring nutrients, enzyme activity, pH, concentrations of microbe phospholipid fatty acids (PLFAs) in soils, and determining concentrations of polyphenols and total flavonoids of H. cordata. The research is aimed to understand characteristics of the planting soils and improve the quality of cultivated H. cordata. The soils at different sample sites varied greatly in nutrients, enzyme activity, pH, microbic PLFAs and polyphenols and all flavonoids. The content of total PLFAs in sample sites was following: bacteria > fungi > actinomyces > nematode. The content of bacteria PLFAs was 37.5%-65.0% at different sample sites. Activities of polyphenol oxidease, concentrations of available P and content of PLFAs of bacteria, actinomyces and total microorganisms in soils were significantly and positively related to the concentrations of polyphenols and total flavonoids of H. cordata, respectively (P < 0.05) . The Content of fungi PLFAs in soils was significantly and negatively related to concentrations of polyphenols and total flavonoids of H. cordata, respectively (P < 0.05). This study provides evidence that effectiveness of the soil nutrient, which may be improved due to transformation of soil microorganisms and enzymes to N and P in the soils, was beneficial to adaptation of H. cordata adapted to different soil conditions, and significantly affects metabolic accumulation of polyphenols and flavonoids of H. cordata.
