Objective To separate the SO-Rb 50cells antigen corresponding to the monoclonal antibody of anti-retinoblastoma. Methods The antigen corresponding to the monoclonal antibody of anti-retinoblastoma was separated elementarily by ion-exchange chromatography, and was identified by dot-blotting using the monoclonal antibody of anti-retinoblastoma. The target protein band of the antigen was separated in light of sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Results A special unmixed band of SO-Rb 50cells antigen was separated with the relative molecular weight of 83?103. Conclusion The antigen corresponding to the monoclonal antibody of anti-retinoblastoma could be separated from SO-Rb 50cells.

After the problems in military postgraduate information literacy education were analyzed, the construction of a systematic and coherent information literacy education course system for military postgraduates in close combination with their subjects was proposed by setting up multidimensional education target, designing three-stage foundation-subject-innovation course, combining traditional literature retrieval course and embedded professional course, combining case teaching, heuristic discussion and innovative talent information literacy training approach, by infiltrating the physical and virtual space both in and outside university, and by participating in the study and research activities of postgraduates.

Data management service abroad provided by subject librarians in biomedical field for scientific researchers, and the model, contents and efficiency of subject librarians-provided biomedical research data management service in NIH were analyzed according to the need for scientific research data management service in biomedical researchers . The enlightenments of biomedical research data management service abroad on the subject service in our library were elaborated .

The quality control in novelty assessment of medical literature was analyzed in terms of its strict process, improvement of its staff literacy, and perfection of information resources, with certain suggestions put for-ward its quality control .

After the problems found in academic information push service and information literacy training of sub-ject librarians in Medical Library of Chinese PLA were analyzed , the concrete contents of subscribing personal RSS products in a certain institute of Academy of Military Medical Sciences and the feedback of its users were described with suggestions put forward for deepening the academic information push service, such as establishing personal RSS account for research rooms and implanting certain RSS subscription contents into the subject service platform.

In order to have a better understanding of the role of medical library in medical information service during the implementation of Healthy China strategy,the need of health information service of the public and medical scientific researchers in implementation of Healthy China strategy were analyzed by outlining the development history and major targets of Healthy China strategy,and how to meet the requirements of the development of Healthy China for medical library was studies,namely by improving its resources development,service patterns and staff construction according to the present situation of big data development,the challenges medical library is faced in users needs,resources,platform,space,professionals and funds,and the opportunities brought about by the expanding requirements,improving information academic level,advancing new technologies,favorable policies and environments with relevant suggestions put forward.

Objective To study the relationships between airway inflammation,reticular basement membrane (RBM) thickness and bronchial hyperresponsiveness (BHR) before and after treatment with inhaled corticosteroids (ICS) in patients with asthma.Methods Twenty-eight patients with asthma (asthma group) were treated with inhaled budesonide (200 μg,twice a day for 12 months).Lung function,bronchoalveolar lavage (BAL) fluid and airway biopsy pathology were carried out before and after treatment.And 10 patients without asthma were acted as control group.Results BAL fluid eosinophils,epithelial cell and mast cell proportions before treatment in asthma group were significantly higher than those in control group [asthma group:(1.60 ±0.11)％,(2.50 ±0.29)％,(0.1100 ±0.0100)％ ;control group:(0.50 ±0.02)％,(1.20 ±0.08)％,(0.0200 ±0.0001)％,P ＜0.01].RBM and smooth muscle thickness were increased in asthma group than those in control group [ asthma group:( 14.25 ± 2.15 ),(0.36 ± 0.01 ) μ m;control group:(4.45 ± 1.22),(0.20 ± 0.01 ) μ m,P ＜ 0.01 ].BAL fluid eosinophils,epithelial cell and mast cell proportions,RBM and smooth muscle thickness decreased after treatment in asthma group [ (0.80 ±0.04)％,(1.60 ±0.07)％,(0.0500 ±0.0020)％,(6.18 ± 1.30) μm,(0.26 ±0.02) μm,P ＜0.01].RBM thickness was negative correlation with methacholine provoking dose which made forced expired volume in one second reduce by 20％ (r =-0.672,P ＜ 0.01 ).Conclusions Airway inflammation,RBM thickness and BHR in patients with asthma are interrelated and improved with ICS.The results of this study support the need for early and long treatment with ICS.

Objective To investigate the numbers of corpus luteum and ovarian follicles and compare the levels of serum prolactin (PRL), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and estradiol (E2 ) in different phases of estrus cycle in female gerbils .Methods Consecutively taking vaginal smears of the gerbils and directly examined under light microscope to distinguish the four phases of the estrus cycle .Hematoxylin and eosin staining was used to histological examination of the gerbil ovaries , and to detect the levels of serum PRL , LH, FSH and E2 by ELISA assay during estrus cycle .Results The proportion of cornified vaginal exfolliated cells could be the basis to distinguish four phases respectively:proestrus, oestrus, metoestrus, and dioestrus.Moreover, there were no significant differences between the numbers of ovarian follicles in different phases of estrus cycle .The numbers of corpus luteum in preoestrus were significantly lower than that in the other phases of estrus cycle ( P <0.05 ) .The levels of serum PRL and LH were increasing constantly from preoestrus to dioestrus , and both reached a peak at dioestrus ( P<0.05 ) .The levels of serum FSH and E2 both peaked at preoestrus , and were significantly higher than those at oestrus , metoestrus and dioestrus ( P<0.05).Conclusions There are no significant differences between the numbers of ovarian follicles in different phases of estrus cycle .Gonadotropin , prolactin and estradiol paly important roles in the regulation of estrous cycle .The phases during which surges of FSH and E 2 occur in Mongolian gerbils are similar to those of rats and mice , while the PRL and LH are different .Our findings provide further reference to the study of reproductive physiology of Mongolian gerbils .

After the scientific research data management service model in Indiana University Library and Massa-chusetts University Library of USA was investigated, the contents, methods and tools of their scientific research data management service were comparatively analyzed and certain suggestions were put forward for scientific research data management service in domestic libraries.

The information was obtained through the open access channels and organized with free markers.The relations in research and development institutions of foreign military medical equipments were determined by analy-zing thecompetitive opponents .The information platform for research and development institutions of foreign mili-tarymedical equipments was constructed using the MVC design model in combination with Web2.0 technology and community concept of resources according to the B/S structure forthe collection, storage, organization, analysis, sharing and evaluation of military medical information resources .
