Objective To investigate the satlsfaction of senior outpatients over 60 years old,and explore the factors associated with their satisfaction so as to provide scientific references for improving quality of care at the hospital Methods A questionnaire survey was made by random sampling at the hospital.The outcomes subject to Ordinal regress Results The general satisfaction was as high as 82.77％ among these outpatients.Results of the Ordinal regression model showed seven factors significantly affecting such satisfaction rate,namely waiting time for registration,correct statement of medicine information,patience to hear patient's concerns,carefulness of inspection,time for doctor-patient communication,request for comments on therapy,and outpatient clinic seating conditions.Conclusion Senior outpatients tend to emphasize medical skills and medical service than waiting time at the hospital.This suggests better medical skills and service attitude as key to higher general satisfaction rate of senior outpatients.

PurposeTo study the effect of gasoline on the extracellular matrix of dermis in rat. Methods45 male Wistar rats were divided into control group, 3 different exposure level groups, which were exposed to gasoline on 2 cm× 3 cm skin area with the dose of 250 mg/cm2 for 1 (group A) ,4(group B)and 8 days (group C) respectively,and an intervention group exposed to 250 mg/cm2 × 8 days gasoline after the application of protective agent on skin. After the treatment, collagen, elastin and glycosaminoglycan (GAG) were assayed in skin departed from intoxicated area.ResultsCompared with control group, collagen was decreased in group C(P<0.05); elastin was decreased in group B and C (P<0.05); glycosaminoglycan was decreased in all exposure groups and intervention group ( P < 0.05 or P < 0.01 )。 Collagen, elastin and glycosaminoglycan(GAG) were significantly lower in group C than in intervention group ( P < 0.05 ). ConclusionsThe extracellular matrix of dermis,including collagen,elastin and GAG were decreased in rat dermal exposed to gasoline.
