Objective To explore the effects of the multidisciplinary cooperative continue nursing on the quality of life of patients with chronic obstructive pulmonary disease (COPD). Methods From December 2012 to December 2014, hospitalized COPD patients who were in the stable stage of disease and would soon be discharged and met the criteria standards were chosen. Convenient extraction of 64 patients were set as the experimental group in one ward and 50 patients as the control group in the other ward. The conventional discharge guidance was employed in the control group. While the continuation of care before discharge and 1, 3, 6 months after discharge was employed in the experimental group. The indexes such as the quality of life and 6 min walking test distance (6MWD) were observed and compared. Results The total scores and symptoms, activities, influence scores of the quality of life were 48.53±15.78, 35.38± 18.61, 57.95 ±23.69, 52.28 ±15.27 after 6 months intervention in the experimental group and 60.24 ±10.14, 52.76 ±12.36, 68.34 ±15.59, 58.55 ±11.79 in the control group, and there were significant differences (t=-5.69--2.38, P<0.05). 6MWD was (267.46 ±64.64) m after 6 months intervention in the experimental group,which was more than that before intervention (169.42±48.46) m, and there was significant difference (t=-9.71, P<0.01). 6MWD was (201.32±53.93) m after 6 months intervention in the control group, which was not significantly better than that in the experimental group (t=5.82, P<0.01). Conclusions The quality of life of patients with COPD can be significantly improved by the multidisciplinary cooperative continue nursing education after discharge.

Generic drug products (test products: drug A, B...) are bioequivalent to an innovator product (reference product) when their bioavailabilities in the same molar dose are similar. Bioavailability is usually expressed by following pharmacokinetic parameters: the area under plasma concentration-time curve (AUC), the maximum plasma concentration (Cmax) and the time of maximum plasma concentration (tmax). This paper used a two period crossover bioequivalence study to develop convenient, friendly user interface software, BA&BE Analysis to statistically process data in clinical pharmacology studies and other areas. The method involves user input of data for analysis into a grid format, setting variables and parameters, followed by one-way analysis of variance (ANOVA), bioavailability and bioequivalence analysis of the data. The software developed in the present study should help scientists to carry out data analysis of bioavailability and bioequivalence testing quickly and easily.
