Objective To explore new method to improve the teaching effects of complete denture prosthetics.Methods Totally 49 students were divided into 6 groups randomly.Lecture-based learning (LBL) combined with problem-based learning (PBL) methods were tried in complete denture prosthetics teaching.LBL teaching was made up of 18 class hours,in which teachers' teaching in the form of lecture was given priority to and introduction to basic theory of complete denture was focused on.PBL teaching was made up of 6 class hours in the form of small class ； the teaching plan ' new dentures of uncle Wang' compiled by the teaching and research section was taken as the blueprint；students searched for the references and discussed on the upcoming problems,relevant reasons and processing methods for wearing new dentures ； students made the final report.The effects were estimated by denture prosthodontics examination and PBL teaching feedback form.Data were described by percentage.Results 93.88％ students passed the exam,67.35％ students got good results.Feedback showed that 77.55％ students hold a positive attitude to PBL teaching.Conclusion Combining LBL with PBL in complete denture prosthetics teaching can achieve satisfactory results.

Objective To investigate the effect of Beraprost Sodium and atorvastatin in the treatment of TIA combined carotid plaques. Method 60 cases in our hospital with TIA and carotid artery plaques were randomly divided into observation group and control group, 30 cases in each group. The observation group was received beraprost natriuretic peptide and atorvastatin calcium therapy, the control group was treated with atorvastatin calcium. 12 months later,two groups were compared with carotid plaque area change and coagulation conditions. Results Carotid plaque area in observed group was significantly less than the control group (P<0.05). The differences of platelet agglutination test(PAgT), fibrinogen(Fg) , hypersensieive 3 C-reaction protein, total cholesterol(TC), high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol (LDL), TIA recurrence rate and incidence of ischemic stroke between two groups after treatment were statistically significant (P<0.05). Conclusion Beraprost Sodium and atorvastatin has a good effect in reducing carotid plaques area, adjusting blood fat and preventing TIA and ischemic stroke, It is worthy to clinical popularization and application.

Objective: To investigate the incidence of human rhinovirus (HRV) infection in hospitalized patients in emergency department. Methods: A total of 94 emergency patients admitted to the emergency department from November to December of 2018 were enrolled in this study. The rhinovirus infection and related risk factors were analyzed. Results: HRV infection occurred in 17 out of 94 hospitalized patients in emergency department, the infection rate was 18.09%; Multiple HRV serotypes were prevalent from November to December of 2018, which were A9, A10, A16, A31, A73, B42 and C3. Elderly patients are at high risk of rhinovirus infection; Rhinovirus infection may increase the course of inpatients. Conclusions From November to December of 2018, multiple serotypes of HRV infections in the emergency department of Bengbu, Anhui, and HRV easily infected elderly inpatients.
