Objective To present the authors' initial experience of treating auricular arteriovenous malformations (AVMs) with ethanol embolization and to assess the clinical effectiveness of this therapeutic method. Methods Twenty-two patients with AVMs were enrolled in this study. Through local puncturing or super-selective catheterization the absolute ethanol, or diluted alcohol (based on the pattern of the AVMs), was manually injected into the abnormal vascular plexus of the auricular lesion. The clinical results were estimated with physical examination or angiography at intervals of 3 ～ 4 month, and telephone questionnaire was made at monthly intervals for all patients. Results Thirty-eight ethanol embolization procedures were performed, the amount of ethanol used during the procedure ranged from 4 ml to 65 ml. After the treatment the clinical symptoms were improved, which were manifested as healing of the ulceration, stop of bleeding, disappearing or alleviation of tinnitus. Angiographic examination showed that the abnormal vascular lesion was completely vanished in 9 cases, decreased by 50% -75% in 8 cases and decreased less than 50% in remaining 5 cases. The common complications included irreversible local necrosis and vesiculation. Conclusion For the treatment of auricular AVMs ethanol embolization is an effective and safe method, which might become the therapy of first choice.

BACKGROUND: Ribavirin is easily diluted by lacrimal fluid and has low bioavailability. In situ ophthalmic gel changes from liquid drug to gel phase upon exposure to physiological conditions, resulting in an increase in the precorneal residence time of drugs. OBJECTIVE: To prepare ribavirin in situ ophthalmic gel and valuate its theological feature. DESIGN, TIME AND SETTING: In vitro controlled observation, performed at the Engineering Research Center of Modem Chinese Medicine Discovery and Preparation Technique, Ministry of Education, Tianjin University of Traditional Chinese Medicine between September and October 2006. MATERIALS: Sodium alginate, Carbopol, and ribavirin. METHODS: Sodium alginate (1% and 2%) and Carbopol (0.3%, 0.6%, and 2%) were combined at different proportions to prepare in sire ophthalmic gel, then in which ribavirin was added. MAIN OUTCOME MEASURES: Viscosity determinations of prepared different concentrations of formulations were determined using a cone and plate viscometer. RESULTS: Ribavirin in situ ophthalmic gel prepared with 1% sodium alginate and 0.6% Carbopol had the largest viscosity. The viscosity change was not influenced by the addition of ribavirin. The in situ ophthalmic gel prepared with sodium alginate and Carbopol changed to the gel phase upon exposure to lacrimal fluid. CONCLUSION: 1% sodium alginate and 0.6% Carbopol produced the best rheological feature and could prolonge the precorneal residence time of drug than that of conventional ophthalmic solution.

Objective To assess left ventricular systolic strain in patients with mitral valve replacement (MVR) by speckle tracking echocardiography. Methods Two-dimensional images were acquired from the apical four-chamber view, two-chamber view and long-axis of the left ventricular view in 30 MVR patients (MVR group) and 30 healthy subjects matched by age and gender(control group), and then were analysed off line to evaluate left ventricular systolic strain. The maximum systolic longitudinal strain(LS) of myocardial segments and global longitudinal strain(GLS) were measured in apical views. Left ventricular ejection fraction(LVEF) was calculated using Simpson's method. The correlation between GLS and LVEF was analyzed using Pearson's method. Results Compared with the control group, LS of corresponding segment and GLS in MVR group decreased significantly (P < 0.01), but there were no statistical differences within MVR group(P>0.05). There was a good linear positive correlation between GLS and LVEF in patients (r = 0.710, P <0.01). Conclusions Speckle tracking eehoeardiography is available for measuring left ventricular systolic strain and estimating global systolic function in patients with MVR. Bull's-eye strain map, created by speckle tracking imaging, can achieve an accurate real-time segmental wall motion analysis.

Analysis on currently used stomatology textbooks for both graduates and postgraduates in China was performed and comparison in stomatology text or reference books between china and American was made.It was found that the types and numbers of stomatology textbooks for both graduates and postgraduates in China were very limited compared with those in American.Many textbooks needed for dental education were insufficient.Great efforts should be made to select relevant topics or titles and to prepare text or reference books accordingly in an aim to meet the needs of today's high quality dental education.

Objective To investigate the satisfaction degree of students and teachers towards PBL teaching method and to provide a basis for continuing to carry out PBL teaching.Methods Anonymous questionnaires of PBL teaching method in teaching plan and procedure was conducted among 49students (2008 grade) and teachers.SPSS 13.0 software package was used to analyze the data and P ＜ 0.05 stands for statistically significant differences.Results Both students and teachers were satisfied.Teachers' evaluation scores of 17 projects were all higher than 4 points and students' evaluation scores of 13 projects were all higher than 4 points; scores for the rest projects were all higher than 3 points.Conclusions PBL teaching method combined with stomatology is effective and measures should be taken to strengthen the management of PBL teaching in stomatology.

The traditional discipline-centered curriculum design can neither keep up with developments of modern medical science nor reach requirements of the education reform in the new century.Since 2011,College of Stomatology in School of Medicine in Shanghai Jiao Tong University had developed ‘ disease oriented integrated curriculum system reform’ for students of long-term stomatology education.In view of the problems existing in the original curriculum system,the integrated curriculum system was set up by coalescing clinical medicine curriculum according to the related systems and oral medicine curriculum according to the developmental rules of diseases.Lectures were combined with discussion classes in the reform and performance appraisal system was changed from simplex judgments into comprehensive evaluations.At last,further considerations of promoting the reform based on the practice were proposed.

The concept and methods of evidence-based medicine(EBM)has been evolved to impact almost all fields of health care and policy since it first appeared in 1992.but in the field of dentistry or stomatology,many problems remain to be solved in carrying out EBM.The necessity and feasibility of implementing evidence-based dentistry education in China were discussed in this paper for chnical evidence-based decision making and clinical research.The contenk teaching approach and accreditation tools for EBM in dental education were also proposed.

Objective To investigate the present situations of anticoagulant treatment of non-valvular atri-al fibrillation in order to get better guidance of the clinical anticoagulant therapy and reduce the incidence of stroke caused by atrial fibrillation. Methods The clinical data of NVAF patients hospitalized in the first affili-ated hospital of Chongqing Medical University from January 1 , 2012 to December 31 , 2014 were retrospectively reviewed and analyzed in terms of basic characteristics , medical treatment plan and INR monitoring. Results A total of 1,390 patients were enrolled, 85.97% of whom needed anticoagulant therapy and 25.18% of whom were treated with anticoagulants. For 15.71% of the NVAF patients treated with warfarin , INR met the standard during hospitalization. In the study, such factors as age, coronary heart disease, history of stroke and history of bleed-ing might affect prescription of anticoagulant drugs. Conclusion Most NVAF patients need anticoagulant thera-py, but the rate of anticoagulant therapy is lower than we expected. Among those patients treated with warfarin during hospitalization , the rate of INR meeting the standard is at a lower level. The novel oral anticoagulants are not in wide use in the clinical practice.
