Objective To explore the effect of early swallowing function training in the prevention of stroke-associated pneumonia(SAP). Methods 78 patients with stroke and swallow dysfunction were divided into training group (n=39) and control group (n=39). All patientswere given routine nursing care, while the training group received early swallowing function training additionally. Clinical data of thetwo groups were compared. Results The incidence of SAP in the training group (25.6%) was lower than the control group (46.2%) (χ2=3.57,P<0.05)。Conclusion Early swallowing function training is effective to prevent stroke-associated pneumonia.

Objective To investigate the repairing effect and mechanism of Chinese patent medicine Weiyangning pill on gastric mucosal injury in rats induced by anhydrous ethanol,and to establish a high-performance liquid chromatography(HPLC)method to determine the five main components of Weiyangning pill.Methods The five components of paeoniflorin,psoralen,atractylenolide Ⅲ,liquiritin and hesperidin in Weiyangning pill were detected by HPLC.SD male rats were randomly divided into normal control group,model control group,Weinaian group,and large and small dose group of Weiyangning pill.All rats were fasted for 24 hours without water fasting.The normal control group and the model control group were given purified water by gavage.While Weinaian group was given Weinaian(3 g·kg-1),the test group were given intragastric perfusion of Weiyangning(3,1.5 g·kg-1)respectively.After 2 hours,all the rats,except the normal control group,were intragastrically administered with anhydrous ethanol(5 mL·kg-1)to establish the model of gastric mucosal injury.An hour later,the experimental materials were collected,and the gross score of gastric mucosal injury was observed and calculated.The gastric mucosal slices were stained by hematoxylin-eosin(HE)to calculate the pathological scores.Immunohistochemistry was employed to detect the expression of gastric mucosa-related proteins.Results The high-performance liquid chromatogram of Weiyangning pill was obtained,and the absorption peaks with the same retention time as the five standard substances(paeoniflorin,psoralen,atractylenolide Ⅲ,liquiritin and hesperidin)were observed.The general score and pathological score of gastric mucosal injury in Weiyangning groups(3,1.5 g·kg-1)were lower than those of the model control group(P<0.05 or P<0.01).Weiyangning pill(3,1.5 g·kg-1)ameliorated the decrease expression of tight junction protein(Claudin-7),adhesion junction proteins(E-cadherin and β-catenin),mucins(MUC1 and MUC5AC),and the gastric transcription factor SOX2 in the gastric mucosa of the rats modeled in anhydrous ethanol(P<0.05 or P<0.01 compared with the model control group).Conclusion The repairing effect of Weiyangning pill on gastric mucosal injury induced by anhydrous ethanol in rats is related to the increase of the expression of tight junction protein,adhesion junction protein,mucin and gastric transcription factor.
