Objective To explore the value of diagnostic laparoscopy on the etiology of complicated abdominal diseases.Methods 31 complicated cases with abdominal pain,ascites and abdominal mass underwent video laparoscopy and biopsy, the comparision in diagnostic grades between laparoscopy, ascites cytology and scanning techniques was done. Result All cases underwent laparoscopy successfully and 97% cases were diagnosed clearly by biopsy and histology, in which the cause of 11 cases(36%)were rare. The grade Ⅰdiagnostic rate of laparoscopy(97%) was higher than ascites cytology(10%) and scanning techniques (19%)(all P

Objective To investigate mechanism involved in the differentiation of FBL-3 cells(eryth-roleukemia cells)induced by dendritic cells(DC). Methods To cultural the FBL-3 cells together with the DC supematant of different concentration for 72 hours,then we used the Wright's staining methed to record the ma-ture monocyte cell population, the transmission electron microscope to observe the ultramicrostructure, the flow eytoraetry to detect the expression rate of the surface molecular CD14. Results The Wright's staining methed, the transmission electron microscope and the flow cytometry all presented that after being induced by the super-natant of the DC ,the FBL-3 cells can partly differentiate into monocytes,inversion monocyte consistent with the personal characteristics. And the intensity of the DC supernatant was connected with interleukin-12. Conclusion The DC supernatant can induce the FBL-3 cells into monocytoid cell, the differentiated cells correspond to monocyte in macro-appearance,uhramicrostructure and phenotype. The competence of the DC supematant are partly concerned with interleukin-12.

Lysozyme, pepsin, ovalbumin, hemoglobin andγ-globumin were chosen as templates to investigate the imprinting capability of amphoteric polyacrylamide cryogels. Prepolymerizing solutions contained acrylic acid and allyl amine, as well as acrylamide and N,N'-methylenebisacrylamide as the functional monomers. As a result there were both acidic and basic functional groups in the polymers, facilitating effective interactions with likewise amphoteric proteins. The proteins differ greatly and cover wide scopes of molecular weights and isoelectric points. Regardless of the values of the molecular weights and isoelectric points, all the templates gave higher retentions on the MIP tubes than on the NIP tube. The MIP of lysozyme indicated the highest imprinting factor of 7. 0, and that of γ-globumin showed the lowest, 2. 0. The values of other proteins were intervenient. Conclusively the amphoteric polyacrylamide cryogels were suitable imprinting materials for various proteins, and could potentially be used for protein recognition, purification, and depletion.

Eggwhitesolutionswereusedas“pendingtemplates”topreparemolecularimprintedpolymers. The obtained polymers acted as stationary phases, exhibiting abilities to deplete abundant proteins in the egg white. The abilities of protein depletion of the imprinted polymers could be adjusted by using different concentrations of egg white in preparing the polymers. After chromatographically processed in a home-made syringe system, abundant proteins such as ovalbumin, lysozyme, and ovotransferrin were removed from egg white sample solutions. Along with the disappearance of the mass spectrum peaks of these proteins, the signals of other components became more obvious. Meanwhile according to reference data and molecular weights, they were reasonably ascribed to be ovalbumin-related proteins, ovotransferrin-related proteins, ovomucoids or flavoproteins respectively. Conclusively, pending imprinting method has the power to deplete abundant proteins, and to retain and enrich posttranslationally modified species at the same time.

Objective To investigate the current situation of knowledge of stroke rehabilitation among Traditional Chinese Medicine (TCM) physicians in 14 tertiary A-level hospitals. Methods A cross section survey was conducted in 14 tertiary A-level hospital in China in May, 2012. A total of 128 TCM physicians completed the questionnaire, which was created according to Medical Care Guideline of Stroke Rehabilitation in China. Results Overall accuracy of stroke rehabilitation basic knowledge was 66.83%, 88.77% of stroke rehabilitation evaluation, 75.12% of stroke rehabilitation treatment. Conclusion The knowledge of stroke rehabilitation is insufficient among TCM physicians in tertiary A-level hospitals, and further training is needed.

Objective:
To investigate knowledge, attitude and behavior related to tuberculosis prevention among primary and elementary school students in Heilongjiang province, and to provide evidence for school-based tuberculosis prevention and control.
Methods:
A cross-sectional survey method was used to conduct a questionnaire survey among 3 033 middle and elementary school students in 10 counties (districts) of Heilongjiang province, including knowledge, attitudes and behaviors related to tuberculosis prevention and treatment.
Results:
In the survey, 61.5% of the students understand the core information of tuberculosis. The core knowledge awareness rate was higher in primary school students (64.8%) than in middle school students(58.1%)(χ2=85.41,P<0.05). Primary and middle school students indicated that the attitude-taking rate of concerns about the tuberculosis patients was 47.5%. Primary school students had more general attitude than middle school students towards willingness to participate in publicity activities compared with primary school students(χ2=39.26,P<0.05). About 85% of students reported personal hygiene habits. The results of multiple linear regression analysis showed that tuberculosis-related knowledge was mainly associated with factors including urban and rural, parental education, health education courses in school(P<0.05).
Conclusion
There is a gap in tuberculosis-related knowledge among primary and middle school students between Heilongjiang province and national level. There’s a need for the improvement of tuberculosis control programs to inform a better understanding and social dissemination of TB information.
