Objective To explore method of establishing and evaluating an asthma rat model with phlegm and blood stasis syndrome.Methods 60 SD male rats were randomly divided into 5 groups,a normal group,asthma group,combination of disease and syndrome(combination)group,DM group,and KCLW group,with 12 rats in each group.Asthma models were established using ovalbumin(OVA).A syndrome model of phlegm and blood stasis was established using a high-fat diet combined with the ice water bath method.We evaluated the asthma model through animal behavior observation,pathological section observation,inflammation index detection,and airway reactivity measurements.The phlegm and blood stasis syndrome model was evaluated via measurements of rat body mass,blood glucose,blood lipids,coagulation function,and hemorheological indexes and by observing symptoms and syndrome determination by Kechuan Liuwei mixture.Results(1)After OVA induction,the rats in the asthma model group and combination group showed symptoms such as shortness of breath,open mouth breathing,abdominal movement,restlessness,and irritability.HE staining showed the disordered arrangement of the bronchial mucosa in lung tissue,local detachment,thickening of the basement membrane and the bronchial tube wall,narrowing of the lumen,extensive infiltration of inflammatory cells,and congestion of capillaries.Compared with the normal group,the asthma model group and combination group(P<0.05)had increased serum IL-4,IL-6,and TGF-β1.Penh values were increased after stimulation with various concentrations of Mch(P<0.05).(2)Rats in the combination group showed symptoms such as chills,curling up with minimal movement,purple and dark claws,purple and black bruises on the tail,loose stools,and unclean perianal area.Compared with the rats in the asthma model group,rats in the combination group had increased body mass(P<0.05)and blood glucose,triglyceride,and total cholesterol levels(P<0.05),a shortened thrombin time(P<0.05),increased fibrinogen content(P<0.05),and significantly increased whole-blood viscosity at low,medium,and high shear rates(P<0.05).The indexes were significantly improved after Kechuan Liuwei mixture administration.Conclusions The asthma rat model with phlegm and blood stasis syndrome can be established through OVA induction and high-fat diet combined with ice water bath.The model can be evaluated through behavioral observation,index measurements,and syndrome determination via formulas.

Objective To develop the Chinese version of depression stigma scale ( DSS) and examine its reliability and validity .Methods The Chinese version of DSS was formed using the standard translation /retroversion method , and its reliability , content validity index ( CVI ) , construct validity , criterion-related validity ( CRV) and discriminant validity were examined subsequently .Results The Cronbach′s αcoefficient for Chinese version of DSS was 0.78 and the test-retest reliability of the scale was 0.74, which was correlated with perceived devaluation-discrimination scale(PDD) significantly (r=0.37,P<0.01).Conclusions The Chinese version of DSS has a good reliability and validity in general population , and can be used to evaluate public′s belief, cognition and behavior toward depression and patients with depression .
