RESUMO
Objective To investigate the optimal self care in lung cancer patients with peripherally inserted central catheter (PICC) in ladder-type nursing training,network education,continuing nursing care clinics,and other forms of nursing mode care.Methods Based on the baselien data of patients in the control group and observation group,PICC self management ability,PICC quantitative data,PICC-related infections,thrombosis,and other complications were compared,and the impact of continued nursing platform on lung cancer patients with indwelling PICC was analyzed.Results In the observation group self management ability and health behavior is higher than that of the control group (P<0.001).PICC catheter -related complications no difference with the control group (P>0.05),Patient satisfaction of the observation group than the control group,the difference was statistically significant (92.18% vs.79.00%,P=0.015).Conclusion The self care based on the continued nursing mode established by PICC speciality nurses can improve the self-management level of patients with PICC,reduce PICC-related complications,and increase the patient's satisfaction.
RESUMO
Objective To observe the effect of aspirin intervention on thrombosis in lung cancer patients with peripherally inserted central catheter (PICC).Methods From December 2007 to June 2012,a total of 997 cases of lung cancer received PICC insertion in Shanghai Chest Hospital.The patients admitted from December 2007 to October 2011 were in the control group (n =562),while those admitted from November 2011to June 2012 were in the intervention group (n =435).The control group received conventional catheterization and saline tube sealing; the study group was treated with the modified Seldinger technique,oral administration of aspirin enteric tablets,and diluted heparin sodium tube sealing.Results The incidence of thrombosis was4.09% (23/562) in the control group and 2.99% (13/435) in the intervention group.In the control group,17 cases of thrombosis occurred within 1 week after catheter insertion,3 between 1 week to 1 month,and 3 after 1 month ; in the intervention group,4 cases of thrombosis occurred within 1 week after catheter insertion,5between 1 week to 1 month,and 4 after 1 month,presenting a significant difference compared with the control group (Z =-2.221,P =0.026).A significant intergroup difference was also observed in terms of thrombus location (Z =-2.066,P =0.039):in the control group,17 cases had thrombus in peripheral superficial vein,and 6 in supraclavicular vein or internal jugular vein; while in the intervention group,5 cases had thrombus in peripheral superficial vein,and 8 in supraclavicular vein or internal jugular vein.Conclusion The prophylactic oral administration of aspirin could effectively reduce the thrombosis in lung cancer patients treated with chemotherapy via PICC.
RESUMO
The most difficult field in gene therapy is that vector system should offer both a means of successful transfection and a maximum of safety for the patient. Viral vectors and plasmid vectors are traditional vectors; they may cause unwanted immunological side effects resulting from the expression of nontherapeutic genes. Our aim is to develop a new general gene therapy vector which is suggested to be called as Micro-Linear Vector. The gene expression cassette is capped by our designed cap, including promoter, enhancer, objective gene, and RNA-stabilizing sequence, so it can defend the exnuclease in the eukaryotic cell, at the same time, DNA not encoding the objective gene is reduced to a minimum. The GFP gene is separated from the pEGFP-N3 plasmid, and acts as a reporter gene to construct the Micro-Linear Vector, then both the new vector and the plasmid are transfected to cells, the results are tested by fluorescence microscope and flow cytometry. The results show that the Micro-Linear Vector has a high effective of transfection and safety in 293, 3T3, CNE2 and B95-8 cell lines, at the same time it is less toxicity than the plasmid. We can get the rudiments of conclusion that Micro-Linear Vector has high effection of the transfection and more safety than tradition plasmid in eukaryotic cell.
