RESUMEN

Objective To carry out health education nursing intervention mode for patients with hemodialy-sis,and to study and analyze the clinical nursing effect.Methods 112 cases of hemodialysis patients were randomlydivided into the observation group and the control group according to random number table,56 cases in each group. The patients of the control group were given conventional nursing model,and the patients of the observation group were given nursing intervention model on the basis of health education.The blood pressure,the internal fistula blockage, indwelling catheter caused by the incidence of infection and blood phosphorus level of compliance rate were compared in the two groups.Results After nursing intervention,diastolic blood pressure(76.17 ±7.02)mmHg and systolic blood pressure (131.17 ±8.77)mmHg of the observation group were significantly better than the control group [(90.91 ±8.44)mmHg,(141.29 ±7.08)mmHg],there were statistically significant differences(t =10.49,13.75, all P <0.05).The incidence rate of fistula obstruction (1.79%)and the catheter infection incidence rate(1.79%) of the observation group were significantly lower than the control group (28.57%,26.79%),there were statistically significant differences(χ2 =8.22,9.17,all P <0.05).The blood phosphorus level standard rate(60.71%)of the observation group was significantly higher than the control group(33.93%),there was statistically significant differ-ence (χ2 =11.45,P <0.05).Conclusion The incidence of complications is significantly decreased after nursing intervention of health education in patients with hemodialysis,and the indexes are improved significantly,and there is no obvious conflict of interest.

RESUMEN

We studied the effect of surfactin on cell proliferation, apoptosis and the cytoskeleton in human breast cancer cell line MCF-7 in vitro. The result of 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) showed that the surfactin inhibited proliferation of MCF-7 cells in a dose- and time-dependent manner, with IC50 at 48 h of 27.3 micromol/L. Surfactin-induced cell death was considered to be apoptotic by observing the typical apoptotic morphological changes by AO/EB staining. Flow cytometric analysis also demonstrated that surfactin caused time-dependent apoptosis of MCF-7 cells through cell arrest at G2/M phase. Immunofluorescence and Western blotting showed that surfactin significantly suppressed the expression of vimentin, induced the alpha-tubulin depolymerization and rearrangement and then the skeleton system of the cells changed dramatically. Based on our findings, surfactin can significantly inhibit the growth of MCF-7 cells and induce apoptosis.
