Objective To identify the nursing interventions and activities for hemiplegic patients in various functions suffered from stroke,and guide clinical practice.Methods Review rehabilitation of evidence-based clinical practice and literature of hemiplegic patients,stroke patients in different functional states were continuously cared and recorded by a researcher.Nursing program was identified according to patients' functions and the sixth edition of Nursing Interventions Classification,8 experts were consulted by a questionnaire survey,which was based on the initial screened nursing interventions and activities,30 nurses and 41 experts were consulted then.Results The established nursing program included 20 interventions and 307 activities.80％-100％ nurses' opinions culminated in consensus on the selected interventions.The selected activities scored 4.00-5.00 in average,with the coefficient of variations ranging from 0.00 to 0.25.Conclusions The established nursing program is convenient to communication and could be a tool to guide the clinical nursing practice.

Objective To investigate the mechanisms of tacrolimus on the migration of Langerhans′ cells. Methods The concentration of MCP-1 in the cultured supernatants of HaCaT cell treated with tacrolimus was determined by ELISA. The expression level of MCP-1 mRNA in HaCaT cell treated with tacrolimus was studied by RT-PCR method. Results The concentration of MCP-1 in HaCaT cell treated with 625 ～ 5 000 ng/mL of tacrolimus was significantly decreased. The expression level of MCP-1 mRNA was also markedly decreased. Conclusions Tacrolimus may probably decrease the expression of MCP-1 in keratinocytes and suppress the chemotactic ability of Langerhans′ cells precursor and Langerhans′ cells, thus inhibiting or diminishing certain local immunoreaction.

Objective To investigate the expression of IL-8 and CXCR2 on keratinocytes from psoriatic lesions and their roles on clinical and pathologic manifestations. Methods The chemotaxis of psoriatic lesional keratinocytes was detected by micropore loculus test. The concentration of IL-8 was determined in the cultured supernatants of psoriatic keratinocytes by ELISA. The expression of CXCR2 on keratinocytes from affected skin was tested by flow cytometry. Results The chemotaxis for neutrophils by the cultured supernatants of psoriatic lesional keratinocytes was significantly stronger than that by controls. The concentration of IL-8 in the cultured supernatants of psoriatic lesional keratinocytes was also increased. The expression of CXCR2 on psoriatic keratinocytes was significantly increased. Conclusions The psoriatic epidermal hyperproliferation may be correlated with up regulation of IL-8 production and CXCR2 expression on psoriatic keratinocytes. At the same time, the psoriatic inflammation may be partly related to the increase of secretion of IL-8, which has chemotactic capacity, by keratinocytes. IL-8 and CXCR2 may be involved in the pathogenesis of psoriasis.

BACKGROUND:Human and rat ovarian granulosa cels in dominant folicles have the phenomenon of expressing stem cel characteristics. OBJECTIVE:To investigate the expression of stem cel-related factors in rat ovarian granulosa cels. METHODS: After the paraffin sections of rat ovarian tissue, immunohistochemical method was used to detect CD34, CD133, ABCG2/Bcrp1, Pou5f1/Oct-4 expressions. Granulosa cels culturedin vitro were harvested by folicular puncture method, and then the immunohistochemical method was used to detect the expression of FSHR receptor in order to identify the purity of granule cels. In the cultured granulosa cels, CD44 and C-Kit expressions were detected immunohistochemicaly, RT-PCR was used to detect ABCG2/Bcrp1, Pou5f1/Oct-4, Nanog gene expressions in ovarian tissue and granulosa cels. RESULTS AND CONCLUSION:Immunohistochemistry detection on paraffin sections showed that a part of ovarian granulosa cels expressed CD34, CD133, ABCG2/Bcrp1 and Pou5f1/Oct-4, and the expression of Pou5f1/Oct-4 protein gradualy increased in the development of ovarian folicles, significantly enhanced during the luteal phase, and then disappeared after the formation of corpus albicans, displaying a periodic expression characteristics. FSHR receptor positive identification rate of primary cels harvested by the foliclar puncture method was more than 95%. Granulosa cels culturedin vitrowere mainly long spindle-shaped or diamond, and some cels presented with aggregation growth and expressed CD44 and C-Kit. RT-PCR test results showed that there were no Nanog in the ovarian tissue and cultured granulosa cels, low expression of Pou5f1/Oct-4 in the ovarian tissue, strong expression of ABCG2/Bcrp1 in the ovarian tissue, weak expression of Pou5f1/Oct-4 in the cultured granulosa cels, and strong expression of ABCG2/Bcrp1 in the cultured granulosa cels. These findings suggest that a part of granulosa cels in the rat ovarian have the characteristics of stem cels.

OBJECTIVETo study the preparation of phenols gastric floating tablet.

METHODThe tablets which were prepared using Eudragit IV, HPMC(K4M), MCC101 and Octadecanol as excipients were evaluated by vitro floatation and releasing performance. The pressure of preparationg was also study to select the optimal preparation.

RESULTThe tablets were successfully prepared in which the drug, Eudragit IV, Octadecanol were 31% respectively,and MCC101 was 7%. And 3-4 kg was found to be the eligible pressure.

CONCLUSIONThe study was found to be effective in the process of phenols gastric floating tablet.

Objective: To construct an expression system containing the N-terminal segment of Thrombospondin-1 (TSP-1) in E. coli. To investigate the activity of TSF. Methods: thbs1 gene fragment was amplified from human fetal cord vein endothelial cells and inserted into plasmid pET32c ( + ) which was then transfected and expressed in E. coli. Investigate the effect of recombinant TSF to the proliferation of ECV304 in vitro with MTT. The expression level of CD36 was assayed by FACS. Results: Recombinant TSF was purified. TSF could restrain the proliferation of ECV304 with CD36 low-expression. Conclusions:Low dose of rTSF was a latent assistant treatment of anti-cancer.
