Atherosclerosis is a chronic inflammatory disease,with both the innate and adaptive immune systems responding to many endogenous and exogenous antigens.Subsequent investigations have revealed that an immunomodulatory strategy via active immunization against atherosclerotic plaque antigen(s) could potentially alleviate atherosclerosis.Substantial data from clinical investigations support the key role of immune system in atherosclerosis.So,it may be promising to develop immunotherapy against atherosclerosis.The paper reviews current status of immunization studies and possible associated immunemediated inflammatory mechanisms in atherosclerosis.

Objective:To investigate the distribution of γδT17,Th17 and Tc17 cells in the lung of mice severely infected by influenza A(H1N1)pdm09 virus and the relationship between these cells with lung immunopathalogical injury.Methods:Intranasal infection was used to establish mouse model of severe H1N1 infection.Flow cytometry assay was used to detect the proportion and number of γδT17 cells,Th17 cells and Tc17 cells in the lung.The concentrations of interleukin-17A(IL-17A),interleukin-1β(IL-1β)and interleukin-23(IL-23) in the bronchoalveolar lavage fluid and serum were assayed by enzyme-linked immunosorbent assay and Lu-minex assay.Results:①The model of mice severely infected by influenza A(H1N1)pdm09 virus was established successfully.②The ratio of γδT cells,but not CD4+T and CD8+T cells in total lymphocytes of the lung of infected mice significantly increased compared with uninfected control mice at the third day post infection(DPI)(P<0.01).③The proportion and number of γδT17 cells,Th17 cells and Tc17 cells in total γδT cells,Th cells and Tc cells in the lung of infected mice were significant higher than that in uninfected control mice at the first DPI,respectively.However,the absolute number of γδT17 cells was far more than Th17 and Tc17 cells(P<0.05);④The concentration of IL-17A in BALF increased significantly after infection(P<0.05),and the concentration of IL-17A in serum increased significantly at the third DPI(P<0.05).The concentrations of both IL-1β and IL-23 in BALF probably participating in the activation of γδT17 cells increased significantly after infection compared with uninfected control mice.Conclusion:The γδT17 cells could be activated and secreted IL-17A via γδTCR non-depended pathway and involved in inflammatory pathological injury of lung at the early stage of severe H1N1 infection.

The Theory of Change holds that the change in a project ’ s effectiveness can be derived from the changing process in the certain context .Only after analyzing changes caused by a project and the possible changing path or hypothesis can we determine the real cause of an effect .In 2012, the maternal, child and community health department of the former Ministry of Health began a comprehensive intervention project for children ’ s health in Nu-jiang Prefecture .The project was designed to explore modes and mechanisms for improving children ’ s health in the west, poverty and ethnic minority areas through cooperation at the national , provincial, and prefecture levels.Based on the Theory of Change , this article describes the logical framework of the comprehensive intervention project .In or-der to lay the foundation for improving the project design , ensuring the implementation of the project and conducting the follow-up monitoring and evaluation , we also expound the goals , implementation strategies , and intervention measures, project activities and output , implementation routes .

ABSTRACT:Objective To evaluate the curative effect of tension-free vaginal tape-obturator (TVT-O)and modified TVT-O in treating female stress urinary incontinence (SUI).Methods We selected 1 1 3 female patients diagnosed with SUI from January to December 2013 in our department and divided them into standard TVT-O group (group A,5 6 cases)and modified TVT-O group (group B,5 7 cases).We evaluated prospectively the safety,short-term efficacy and complications of operation in the two groups.Results The length from bilateral obturator membrane to the puncture point in the skin was greater in group A than in group B.The average intraoperative blood loss was more in group A than in group B.The median NRS score of postoperatie thigh pain in group A was higher than in group B (P<0 .0 5 ).The two groups did not differ significantly in operation duration,postoperative catheterization,mean hospital stay duration,the length and position from bilateral obturator membrane to the puncture point,or surgical efficacy (P>0.05).Conclusion Both TVT-O and modified TVT-O techniques are effective in treating female SUI.Modified TVT-O has a short path to get through the adductor muscles and less intraoperative blood loss;therefore,it can significantly reduce the complications such as postoperative pain to enhance the quality of life after operation.

Objective To investigate the feasibility of rat sodium/iodide symporter (rNIS) as a reporter gene monitoring rat bone marrow mesenchymal cells (rBMSC) transplanted to rat myocardium in vivo.Methods Recombinated adenovirus vector was constructed by rNIS/enhanced green fluorescence protein (EGFP) (Ad-rNIS/EGFP).rBMSC transfected by Ad-rNIS/EGFP were studied using fluorescence microscope.Fifteen rats were transplanted with rBMSC and randomly divided into three groups:rNIS group (with rNIS transfection), blocked group (with rNIS transfection) by oral intake of perchloric sodium before planar imaging(GE Millennium MPR SPECT), and control group (without rNIS transfection).All rats underwent 99Tcm-pertechnetate planar imaging.The biological distribution of 99Tcm-pertechnetate was studied.The expressions of rNIS gene and protein in myocardium were measured by real time polymerase chain reaction (PCR) and western blot, respectively.The expressions of CD29, CD44, CD90, CD11b, CD34 and CD45 were measured by immunohistochemistry.Results rBMSC transfected by Ad-rNIS/EGFP showed EGFP expression under fluorescence microscope.The transplanted rat myocardium could be visualized on 99Tcm-pertechnetate planar imaging in rNIS group.The relative uptake ratio( Rheart/Rhmb, RUR) was 6.7 ±0.4.RUR in control group (3.0 ±0.2) was lower than that in rNIS group (t =2.78, P=0.03).The percentage injection dose per gram of tissue (% ID/g) of the transplanted myocardium was 60.2 ± 20.8 in rNIS group,which was higher than that (2.5 ± 0.4) % ID/g of control group ( t = 7.13, P<0.001 ).rNIS gene and protein were highly expressed in transplanted myocardium in rNIS group but less expressed in control group.The expressions of CD29, CD44 and CD90 were positive, CD45 and CD45 negative CD11b mildly positive in the myocardium transplanted with infective rBMSC.Conclusion rNIS can efficiently monitor rBMSC transplanted to rat myocardium.

OBJECTIVEThe study was designed to investigate the expression patterns of metalloproteinase (MMP)-13 protein in invasive breast carcinoma and to determine the clinicopathological and prognostic values of its various localization and relation to the tumor phenotypes.
METHODSImmunohistochemistry was performed on paraffin-embedded tissue array from 263 invasive breast carcinomas to investigate the protein expressions of MMP-13, estrogen receptor, progesterone receptor, HER2, MMP-2, MMP-9 and tissue inhibitor of matrix metalloproteinases (TIMP)-1, TIMP-2.
RESULTSMMP-13 protein was detected in the cytoplasm of carcinoma cells and peritumoral fibroblasts. High level expression of MMP-13 protein in tumor cells was associated with more lymph node involvement and higher tumor grade (both P < 0.01), and positively correlated with HER2 (P = 0.015) and TIMP-1 protein (P < 0.01) expression in carcinoma cells. Moreover, high expression of MMP-13 was associated with shortened overall survival for the entire patient population and the patient group with positive lymph node. Tumor cell derived MMP-13 had different impact on patients with different HER2 status. Peritumoral fibroblasts derived MMP-13 protein, although correlated with tumor cell derived MMP-13 and associated with lymph node stage and HER2 expression, was found having less prognostic impact. Univariate survival analysis showed that the tumor size, grade, lymph node status, PR status, HER2 expression, tumors TIMP-1 and MMP-13 expression were prognostic factors. However, multivariate survival analysis showed that only tumor size, lymph node status, HER2 expression, tumors TIMP-1 and MMP-13 were independent prognostic factors.
CONCLUSIONMMP-13 protein expressed by tumor cells correlates with the invasion and metastasis of breast carcinoma, and therefore, may serve as a poor prognostic marker for the patient.
