Objective To evaluate the effect of training for therapists based on Kirkpatrick's Four-level Model. Methods Totally 39 ther-apists who completed 2014 Beijing Clinical Shortage of Manpower Training Programs (Therapist) were investigated with Kirkpatrick's Four-level Model, named reaction, learning, behavior and results. Results For reaction level, the total satisfaction was high, but different with the degree of education, especially in the items of Participate in Training, Type of Cases, Organizing on Practice Training, Organizing Case Discussions and Get A Lot of Benefits from the Training (F>4.59, P<0.05). For learning level, the test scores were significantly differ-ent before and after the training (t>9.53, P<0.001). For behavior level, the self-reports of the therapists, and the reports from their depart-ment directors and colleagues all agreed that their ability improved after training (t>4.44, P<0.001). For results level, eleven therapists passed the rehabilitation therapist test, two therapists participated in some researches, and one published an article. Conclusion The thera-pists satisfied in the training, that may improve the ability of therapists to contribute to their organization.

Intestinal schistosomiasis is a kind of intravascular parasitic diseases, and chronic inflammation of colon is one of the basic pathological changes of the sickness.However, the mechanism of caveolin-1 and tight junction proteins in the pathogenesis of intestinal schistosomiasis is still unclear.Aims: To study the expressions and significances of caveolin-1 and tight junction protein occludin, claudin-1 in schistosomiasis colitis in mice.Methods: Forty BALB/c male mice were randomly divided into control group and infection group.Schistosomiasis colitis model was established by placing 40 Schistosoma Japonicum cercarie on the abdomen.Mice were sacrificed after 8 weeks.HE staining was performed.The permeability of intestinal vascular endothelium was detected by Evans blue method.The leukocyte counts in peritoneal lavage fluid were measured.qPCR was used to determine the mRNA expressions of caveolin-1, occludin, claudin-1 and eNOS in colon tissue.Western blotting and immunohistochemistry were used to detect the protein expressions of caveolin-1 and occludin.Results: Large number of egg granuloma was observed in colon submucosa and accompanied by extensive inflammatory cells infiltration in infection group.Compared with control group, content of Evans blue and leukocyte counts in peritoneal lavage fluid were significantly increased (P<0.05);mRNA expressions of caveolin-1, occludin, claudin-1 were significantly decreased (P<0.01);protein expressions and positivity rates of caveolin-1 and occludin were significantly decreased in infection group (P<0.05).Conclusions: Down-regulation of expressions of caveolin-1, occludin and claudin-1 can induce leukocyte accumulation via increasing the permeability of intestinal vascular endothelial cells, thereby involving in the development of schistosomiasis colitis.

To explore the new pattern of Chinese medicine solid preparations (CMSP) in vitro dissolution, a method testing the bio-thermal activity in combination with UPLC was used. Microcalorimetry was used to obtain the characteristic metabolic growth power-time curves and a series of biothermodynamic parameters of the inhibition of Staphylococcus aureus by Yinhuang tablet dissolving solutions at the pH 6.8 (phosphate buffer) dissolution medium at different times. From these results, the cumulative dissolution of Yinhuang tablet based on bio-thermal activity was obtained. The dissolution rates of two components of chlorogenic acid and baicalin were determined by UPLC method. Then f2 similar factor method was used to evaluate the relevance of these two methods. The result showed that f2 values all were more than 50, indicating that there is a good correlation between the two methods of measuring the dissolution rate. It is feasible to determine CMSP in vitro dissolution by using bio-thermal activity, and to provide new evaluation methods for controlling the quality of CMSP.
