ABSTRACT
Objective To establish a method for isolating and culturing fibroblasts from cirrhotic liver in vitro,observe the biological characteristics of fibroblasts.Methods Human fibroblasts from cirrhotic liver were isolated and cultured by adhering to the culture plastic.The morphologic and growth characteristics of the acquired cells were observed by microscopy imaging and cell counting.The expression of FSP-1 and Vimentin of fibroblasts was detected through immunofluorescence and western blotting.Results The tissue blocks were well-adherent to the culture plastic within 2 hours.Hepatocyte-like cells were observed surrounding the blocks within about 1 week,and spindle-shaped fibroblasts were observed within about 2 weeks.After a series of passage,the attached cells became proliferated quickly.The growth curves of the passage 3,4 and 5 were quite similar.The result of immunofluorescence showed the expression of FSP1 and Vimentin was positive.The positive rate was respectively (90.6 ± 1.0) ％ and (91.2-± 4.1) ％.Conclusions Human fibroblasts from cirrhotic liver can be cultured successfully through adherent property.The method for isolation and culture of fibroblasts from cirrhotic liver is convenient,efficient,stable and cultured cells remain naive biological characteristics.
ABSTRACT
Objective To summarize the main results and characters of the research literature by reviewing systematically and comprehensively,we get an overall awareness of the current status of the nursing needs of the aged at home and discover the deficiency.Consequently,we provide evidence to improve the nursing services for the aged at home.Methods We systematically searched CNKI (1979-2014.5),CBM (1978-2014.5)and VIP (1989-2014.5).According to the including criteria and excluding criteria,we screened the literature twice.Main results and characters of the literature were described.Results A total of 975 articles were included.The first literature were published in 1986.From 2006,the amount of the literature increased annually.42.36％ (413/975)of the research types were descriptive research.The contents of the literature mainly focused on the need of comprehensive nursing services,such as community nursing services [37.44％(365/975)];home care [20.10％(196/975)];long-term care [10.26％(100/975)].The overall quality of the hterature was not high.Experimental research and descriptive research were implemented mostly in developed areas.The 46.97％(458/975) of the first authors worked in hospitals.Conclusions There is a small quantity of literature published with low quality.Questionnaire with comprehensive items describing needs demanded by the aged are required.We should put an eye on the aged living in undeveloped areas or with recognition impairment.Meanwhile,depending on the general hospital,we should carry out high-quality experimental research,as well as exploring multidisciplinary model.
ABSTRACT
Objective To test the reliability and validity of the self-assessed questionnaire of the elderly health care needs.Methods Based on the Zuluaga-Raysmith model, the initial questionnaire was formulated by literature reviewing and interviews.Through Delphi experts consultation, a questionnaire containing 12 factors, 61 items was constructed.A total of 750 elderly residents were investigated to test the reliability and validity of the questionnaire.Results The effective rate of questionnaires was 88.67％ (665/750).The total Cronbach α was 0.871.The test-retest reliability of all the items were all greater than 0.75.The item-level content validity index were all greater than 0.80.The scale-level content validity index was 0.95.14 factors were extracted by exploratory factor analysis, explaining 66.653％ of the total variance.Conclusions The elderly health care needs self-assessed questionnaire is comprehensive with good stability, which can be used in a multi-center, large sample research.The research may help to get a deep understanding of health care needs of the elderly as well as influencing factors.
