BACKGROUND:The biological extracellular matrix materials become the focus of pelvic floor repair materials research because of its excellent biocompatibility and mechanical compatibility. However, bacterial infection can damage the function of biological repair materials. ＜br> OBJECTIVE:To prepare the biologic antimicrobial materials for pelvic tissue function repair. ＜br> METHODS:Chitosan and tigecycline-loaded chitosan nanoparticles suspension was prepared by the electrostatic adsorption and self-aggregation of nanoparticles preparation techniques. Then the suspension was coated onto the surface of extracellular matrix materials. The morphological examination was performed by scanning electron microscope. The antibacterial property was detected by solid plate microbial culture method. ＜br> RESULTS AND CONCLUSION:Infrared spectra displayed that aromatic ring skeleton vibration peak of chitosan occurred on the biologic antimicrobial materials, and it was significantly widened at about 3 359 cm-1, indicating the composite coating was successful to modify the surface of extracellular matrix materials. As a very smal dose of tigecycline, there was no characteristic absorption peak on the infrared spectra. Scanning electron microscopy showed the porous structure of the material surface with some nanoparticles adhesion. The prepared materials had good antibacterial properties on Staphylococcus aureus and Escherichia coli, and the inhibition zone diameter was significantly increased with the increasing concentration of antibacterial agent. The biologic antimicrobial materials for pelvic tissue function repair were prepared successful y.

Objective To set up an antibody-capture ELISA method to detect the Japanese encephalitis virus(JEV)antibody.Methods ELISA plate was coated with the monoclonal antibody which was specific to the envelope protein epitope E39 of JEV,JEV SA14-14-2 strain as the source of antigen was used to absorb the monoclonal antibody,the absorbed virus used to capture the JEV'S antibody.The antibody that captured ELISA was established.The indirect ELISA method using the virus particles from cell culture was compared with coating ELISA plate,105 clinical serum were checked.Results The background in indirect ELISA assay could not be abscised,positive and negative serum diluted in a ratio of 1:10,1:100,1:1000,the relative value of A posative/A negative were 1.02,0.99,1.13,all<2.1.But the antibody-captured ELISA method when the serum dilution was 1:10,1:100,the A posative/A negative were 3.57,2.94,all>2.1;when the dilution was 1:1000,the A posative/A negative was 1.42,<2.1,it meant the method could distinguish the positive and negative serum efficiently when the dilution Was 1:100,the background problem in indirect ELISA assay could be solved.Antibody-capture method was used to check 105 serum samples,the A posative/A negative over a range of 0.257～0.321(0.262±0.050),all<2.1,no positive sample found.Conclusion The antibody-capture ELISA method has been preliminary set up with a high specificity,capable of quickly identifying JEV from other virus.

Ovbective To study the perioperative changes in neurohormonal factors and hemodynamics in rheumatic valve disease. Methods Method: The neurohormaonal factors, including catecholamine (CA), angiotesin II (AGII), aldosterone (ALD), atrial natriuretic factor (ANP) and hemodynamics were studies in twenty-four patients with rheumatic valve disease (RVD). 7 congenital heart disease (CHD) as the control group. Results Plasma CA, AGII, ALD and ANP were higher preoperatively in RVD groups than that in CHD group, and significantly rose during cardiopulmonary bypass in RVD groups. Conclusion There is a hyperaldosteronism in patients with mitral valve disease during perioperative period. The high systemic resistance is closely related to significantly high levels of plasma NA and AGII during operation and in the early stage after operation. In patients with mitral valve disease and pulmonary hypertension, most of pulmonary pressure and resistance decrease in the early stage after operation.

Objective To explore economic valuation of the minimally invasive esophagectomy.Methods The cases undergone esophagectomy were studied retrospectively.Monofactorial analysis was done to evaluate the impact of various factors on the overall hospitalization costs.The correlated factors then were used as independent variables to carry out the multiple linear regression aimed at the hospitalization costs.Results The results of monofactorial analysis showed that the accompanying diseases,days during hospitalization,modes of esophagectomy,postoperative complications were correlated factors of the overall hospitalization costs.According to the multiple linear regression,it were sorted based on descending order duing to its effect of largenning the hospitalization costs:postoperative complications (β =0.439,P =0.000),days during hospitalization (β =0.397,P =0.000),accompanying diseases(β =0.257,P =0.000),modes of esophagectomy(β =0.132,P =0.000).The expenses caused immediately by the operations were statistically more of the minimally invasive surgery than that of the open procedures whatever the numerous or proportion of the overall costs (P =0.000).Conclusion Combined thoracoscopic and laparoscopic esophagectomy was more expensive than open operation.Nevertheless,impact of the other factors,such as postoperative complications,were more significant than that of the different procedure.h was a strategy to minimally invasive osophagectomy that hospitalization costs could be reduced by means of controlling complications and diminishing hospitalization days.

Objective The aim of this study was to investigate the diagnostic value of the intravoxel incoherent motion (IVIM) for discriminating nonmetastatic from metastatic mediastinal lymph nodes in lung cancer.Methods IVIM was performed preoperatively on 66 patients with lung cancer during October 2015 to June 2016 in Capital Medical University Affiliated Beijing Chaoyang Hospital.Preoperative examination including the chest MRI scan,chest CT,head MRI,bone scan-ning and the cardiopulmonary function.None of the patients was undergone any kind of treatment about the cancer before the examinations,the neoadjuvant chemotherapy or radiation therapy,immunotherapy and gene targeted therapy were included.Measured the short axis diameter and the IVIM parameters of the mediastinal lymph nodes,apparent diffusion coefficient(ADC),diffusion coefficient(D),pseudo-diffusion coefficient(D *),and perfusion fraction(f).All the patients underwent the lobectomy or wedge resection and lymph node dissection or systematic sampling.By comparing the IVIM parameters of the nonmetastatic and metastatic mediastinal lymph nodes according to the pathological examination,draw the ROC curves to find the best cutoff value for diagnosis.And 42 cases were used to comparing the value of the MRI and CT in differential diagnosis.Results MRI measured 184 groups mediastinal lymph nodes,including 164 groups without metastasis,20 groups with metastasis.The ADC,D,D *,f values and short axis diameter of the nonmetastatic lymph nodes(n =164) were(2.880 ± 0.785) × 10-3 mm2/s,(0.670 ± 0.179) × 10-3 mm2/s,(0.383 ± 0.123) × 10-3 mm2/s,0.422 ± 0.119,(6.546 ± 1.932) mm,respectively,and (1.897 ±0.657) × 10-3 mm2/s,(0.472 ±0.210) × 10-3 mm2/s,(0.354 ±0.130) × 10-3 mm2/s,0.412 ±0.090,(7.510 ± 2.773) mm respectively for the metastatic lymph nodes (n =20).The ADC and D value of the nonmetastatic lymph nodes were significantly higher than the metastatic lymph nodes(P ＜0.01).While the other paraneters(D *,f,and short axis diameter) between the two groups did not show significantly different.Optimal cutoff values(area under the curve,sensitivity,and specificity) for distinguishing metastatic from nonmetastatic lymph nodes were as follows:ADC =1.890 × 10-3 mm2/s (0.871,92.7％,80.0％);and D =0.648 × 10-3mm2/s(0.740,70.0％,84.1％).Conclusion IVIM is useful to distinguish metastatic from nonmetastatic lymph nodes in lung cancer.The ADC and the D values are significant higher in metastatic lymph nodes,which more sensitive than the other parameters(D *,f,and short axis diameter).As a result,IVIM can be used in the N-stage diagnosis of lung cancer.
