Objective To learn about the state of anxiety, related factors and demand of the family members of youngster patients with eye traumas during the operations, to improve the quality of nursing care by effectively relieve the anxiety of family memebers through appropriate intervention. Methods The anxiety and needs of family members of 148 children patients with eye traumas were investigated during the perioperative period with self-rating anxiety scale and self-designed questionnaires, and appropriate nursing was given according to the survey results. Results The anxiety score of family members was (56.93 ± 14.72), which was at higher level when the patients were just admitted. The scores statistically de creased after nursing care. The anxiety was related to factors such as the security and the effect of the operation, the technical level of the surgeon, the anesthesia method (general anesthesia),the age of the children patients and the emergency operation. Conclusions Nursing staff can effectively relieve the anxiety of the family members of children patients during perioperative period by supplying special care according to their different demands.

ObjectiveTo investigate the condition and method of a long time mesenchymal stem cell (MSCs) culture with outer space cell living system carried by a recoverable satellite.MethodsMSCs were obtained from 1 week New Zealand rabbits, and seeded to culture flask and outer space cell living system. Under the condition of absence O2, CO2 and medium unable changed, influence of monolayer culture and outer space cell living system upon survival of long time MSCs culture in simulated space various temperature was observed.ResultsUnder the condition of absence O2, CO2 and medium unable changed, monolayer cultured MSCs were maintained to survive for 15 days, and group of space MSCs were successfully maintained to survive for 30 days in outer space cell living system. There was a significant difference between two methods. ConclusionOuter space cell living system can maintain MSCs to survive for 30 days under space flight temperature.
