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.

Two-stage designs for the assessment of bioequivalence have been recently accepted in various regulatory authorities.However controlling type Ⅰ error rates around 5％ at targeted power is still a great challenge for applying two-stage method.This paper reviewed the feature of present designs of the two-stage bioequivalence.The decision tree,nominal significance level,and sample size recalculation in previously published methods were also introduced in detail,which would be referential for domestic sponsors in the study of two-stage design bioequivalence.

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.

Methods Total RNA was extracted from MCF-7 cells,and the full-length of H1 9 lncRNA was amplified by RT-PCR and subcloned into pcDNA3.1 (-)ex-pression vector.The constructed H1 9 expression vector was transfected into HEK-293T and COS-7 cells and the H1 9 lncRNA expression was evaluated by real-time PCR.Following the transfection of H1 9 expression vec-tor into MCF-7 cells for 0,24h and 48h and H1 9 siR-NA interference fragment into MCF-7 cells for 24h, MCF-7 cell proliferation was determined by MTS as-say.Results A hH1 9-pcDNA3.1 (-)expression vector was successfully constructed. At Forty-eight hours after the transfection with H1 9 expression vector in to MCF-7 cells,cell proliferation was significantly increased in the transfected group compared to those without transfection and to those transfected with a neg-ative control vector,while twenty-four hours after the transfection with H1 9 siRNA interference fragment into MCF-7 cells,cell proliferation was significantly de-creased in the transfected group compared to those transfected with a negative control vector.Conclusion Ectopic overexpression of H1 9 lncRNA can promote breast cancer MCF-7 cell proliferation.

Objective To observe the therapeutic effects of urolithin A(UA)on respiratory syncytial virus(RSV)-induced lung infection in neonatal mice and explore the underlying mechanisms.Methods Babl/c mice(5-7 days old)were subjected to nasal instillation of RSV and received intraperitoneal injection of saline or 2.5,5 and 10 mg/kg UA 2 h after the infection and then once daily for 2 weeks.Bronchoalveolar lavage fluid(BALF)was then collected for detection of inflammatory cells and mediators,and lung pathology was evaluated with HE staining.RSV-infected BEAS-2B cells were treated with 2.5,5 or 10 μmol/L UA.Inflammatory factors,cell viability,apoptosis and autophagy were analyzed using ELISA,CCK-8 assay,TUNEL staining,flow cytometry,Western blotting and immunofluorescence staining.The cellular expressions of miR-136 and Sirt1 mRNAs were detected using qRT-PCR.A dual-luciferase reporter system was used to verify the binding between miR-136 and Sirt1.Results In neonatal Babl/c mice,RSV infection caused obvious lung pathologies,promoted pulmonary cell apoptosis and LC3-Ⅱ/Ⅰ,Beclin-1 and miR-136 expressions,and increased the total cell number,inflammatory cells and factors in the BALF and decreased p62 and Sirt1 expressions.All these changes were alleviated dose-dependently by UA.In BEAS-2B cells,RSV infection significantly increased cell apoptosis,LC3B-positive cells and miR-136 expression and reduced Sirt1 expression(P<0.01),which were dose-dependently attenuated by UA.Dual-luciferase reporter assay confirmed the binding between miR-136 and Sirt1.In RSV-infected BEAS-2B cells with UA treatment,overexpression of miR-136 and Ex527 treatment both significantly increased the inflammatory factors and cell apoptosis but decreased LC3B expression,and these changes were further enhanced by their combined treatment.Conclusion UA ameliorates RSV-induced lung infection in neonatal mice by activating miR-136-mediated Sirt1 signaling pathway.
