ObjectiveTo study the factors which affect the nurses' implementation of cardiac rehabilitation. MethodsData of 134 nurses who worked or are working in cardiology ward in No.1 and No.2 hospital of China Medical University was analyzed by using descriptive and inferential statistics.ResultsThe overall barriers is at a moderate level. The types of the barriers in order of mean score were no formal rehabilitation program, lack of knowledge, lack of facility, lack of support, and lack of understanding. Conclusions In order to improve the motivation of nurses to implement cardiac rehabilitation nursing, something must be done to improve nursing practice , nursing administration, and nursing education.

Objective To investigate the in vitro effects of human bone marrow derived mesenchymal stem cells (hBMSC) on Th17 cells of the human peripheral blood.Methods The density gradient centrifugation combined with lymphocyte separation medium was used to isolate hBMSC,which were then cultured.Cytokine IL-17 in the peripheral blood from a healthy person was measured by enzyme-linked immunosorbent assay (ELISA).Proportion of Th17 cells was evaluated by flow cytometry.Results The expression level of IL-17 in spent culture supernatant of the healthy person PBMC and AML hBMSC was (292.32±37.25) pg/ml,and was significantly higher than that of the healthy person PBMC and healthy hBMSC [(169.64±17.47) pg/ml,P ＜ 0.01].There was no significant difference between the expression level of IL-17 in spent culture supernatant of the healthy person PBMC and ALL hBMSC [(159.89±23.71) pg/ml] and the level of the healthy person PBMC and hBMSC.The percentages of Th17 cells of co-culture systems from hBMSC,ALL-hBMSC,and AML-hBMSC and PBMC were (10.13±2.19) ％,(13.77±4.04) ％ and (21.53±5.05) ％,respectively,with the result between AML patients and healthy people being statistically different (P ＜ 0.01).ALL patients and healthy people showed no difference (P ＞ 0.05).Conclusion AML-hBMSC promotes the CD~ T cells to generate Th17 cells,which suggests that the MSC from AML marrow may play a role in the regulation of immune suppression.

To probe into the effect on the viscosity of distilled water natural water Nacl solution and glucose solution by He-Ne Laser. Ubbohde＇s viscosimeter was used to examine the solutions treated by different times of irradiation under the action of certain Laser power to determine its viscosity. He-Ne Laser has not an effect on the viscosity of distilled water and NaCl solution. Effect on the viscosity of the natural water by He-Ne Laser ,the irradiating times in ten minutes, the viscosity of natural water is markedly lower than that from control groups, which are significantly different(P <0.05)the irradiating times beyond ten minutes, the viscosity of natural water is markedly higher than that from control groups ,which are significantly different (P <0.05).the viscosity of the glucose solution irradiated by He-Ne Laser are lower than that from control groups, but which aren＇t significantly different (P >0.05)

OBJECTIVE To study the drug-resistant diversity of Gram-negative bacilli isolated from inpatients during recent five years.METHODS A total of 1 464 Gram-negative bacilli isolated were detected and retrospectively analyzed from 1999 to 2003.Antimicrobial susceptibility testing was performed using Kirby-Bauer method.RESULTS The resistance of Pseudomonas aeruginosa to piperacillin rised from 17.6% of 1999 to 79.2% of 2003,and that to ciprofloxacin rised from 4.3% of 1999 to 36.0% of 2003.The resistance of Escherichia coli to quinolones was above 50%,while to third-generation cephalosporins was 30-40%;the resistance of E.coli to piperacillin rised from 42.9% of 1999 to 68.9% of 2003,and that to ciprofloxacin rised from 40.0% of 1999 to 73.5% of 2003.The resistance of Acinetobacter to piperacillin rised from 31.2% of 1999 to 67.5% of 2003,and that to ceftriaxone rised from 36.0% of 1999 to 74.1% of 2003.The resistance of Serratia to ceftazidime,ceftriaxone,gentamicin,amikacin and piperacillin rised sharply.Imipenem was the most active antibiotic tested against Gram-negative bacilli.Cefoperazone/sulbactam and piperacillin/tazobactam also showed excellent activity against Gram-negative bacilli.CONCLUSIONS During recent five years,the resistance of the most common Gram-negative bacilli has increased rapidly.How to delay the resistance development of common strains become a global problem.

AIM:To investigate the effects of estrogen on the expression of matrix metalloproteinases-2(MMP-2), tissue inhibitor of metalloproteinases-2(TIMP-2) and transforming growth factor-β1(TGF-β1) in cultured human corneal stromal cells.METHODS: Inflammatory environments of human corneal stromal cells were simulated by using 1.5ng/mL IL-1β.The cells were then treated with or without different concentrations of estrogen(0, 1×10-4, 1×10-6, 1×10-8, 1×10-10mol/L estradiol)in vitro.Cell viability was evaluated by MTT.Expression levels of MMP-2, TIMP-2 and TGF-β1 proteins were measured by enzyme-linked immunosorbent assay(ELISA).RESULTS:Estrogen did not affect the viability of human corneal stromal cells.Compared with the control group, expression levels of MMP-2 and TGF-β1 proteins in E2 treatment group significantly decreased after being treated with estrogen, while the expression level of TIMP-2 significantly increased.CONCLUSION: Estrogen could, to some extent, down-regulate the expression of MMP-2 and TGF-β1 and up-regulate the expression of TIMP-2, which might contribute to protecting human cornea.
