Objectives:To evaluate the nursing diagnostic items in perioperative patients, its indication and clinical directive effect. To explore the conception and goal of perioperative nursing diagnosis and the method of making diagnosis from theories, identifying and using them from theories and practice, and to discuss the training method and positive outcomes from quality management. Methods: One thousand and fifty items of nursing diagnosis were collected from 10 surgical units and 20 items were screened from them. Continuous practice and improvement was done by a cycling model: training nurses use items examine nurses analyze outcome find out problems and causes plan and apply interventions. The consistency of the diagnosis and the outcomes of the patients were also compared. Results: The nursing quality of 10 surgical units was improved markedly from 2001 to 2002. Conclusions:The screened 20 items are commonly used in perioperative patients. If used correctly, they could play a strong pragmatic and directive role in nursing practice. Theoretical training and practice are the key to the correct diagnosis and nursing care.

AIM and METHODS: The effects of angiotensin II(AngII) on the activation of three transcription factors were investigated by using EMSA and western-blot methods in endothelial cells respectively. RESULTS: The EMSA results showed that AngII stimulation could increase NF-κB, SP-1 and AP-1 activation in ECV304, which suggested that activity changes in these three transcription factors could partly contribute to the dysfunction of endothelial cells.The binding affinity of NF-κB, SP-1 and AP-1 with corresponding oligonucleotides in AngII-treated ECV-304 were respectively 10.98,3.89,1.33 times as large as in control. The nuclear appearance of AngII-activated NF-κB was examined by western-blot, which corroborates our results from EMSA analysis. While as the protein appearance of AP-1 and SP-1 in nucleus, were little higher than the control group. The result of western-blot suggested that AngII-induced EC activation of these three transcription factors maybe mainly due to the enhanced binding ability to its corresponding cis-acting factors. CONCLUSION: NF-κB, a ubiquitously exposed nuclear transcription factor, is involved, together with SP-1,AP-1, in the regulation of endothelial cell dysfunction related to cardiovascular diseases such as atherosclerosis and hypertension.

Objective To study the potential efficacy of transplanted bone marrow-derived mesenchymal stem cells (MSCs) in treating and repairing the acute lung injury in animal models. Methods MSCs were isolated from mouse bone marrow, cultrued and amplified in vitro. The lipopolysaccharide (LPS) was inhaled through postnasal tract to cause acute lung injury in mice and the MSCs labeled by Brdu were administrated via vein into the mice. The migration and differention of the cells were identified by immunostaining and double immunostaining. The pathological changes, pulmonary edema index and the content of IL-1β in lung homogenate were used to accese the therapeutical effect of MSCs. Results The cultured MSCs dispalyed a positive CD44 and a negative CD34. The Brdu-labeled cells were detected in the lungs of the recipient 4 days after transplantation, indicating its origin of MSCs. Theses cells also exhibited characteristics of aveolar epithelials, expressing the cytokeratin-the marker of epithelium. Compared with the injuried ones, the mice treated with MSCs showed a decreased pulmonary edema in-dex and IL-1β content in the lung homogenate. Conclusion These data suggest a therapeutical effects of MSCs in treating and repairing the mouse acute lung injury.
