Originalresearcharticlesincluding randomized trials,intervention studies,studies of screening and diagnostic tests,cohort studies,cost-effectiveness analyses and case control studies should be prepared in accordance w ith theUniformRequirementsfor ManuscriptsSubmittedtoBiomedicalJournals(www.icmje.org).Those of randomized controlled trials(RCTs)should follow the CONSORT-statement(www.consort-statement.org).The reporting of other articles should follow the guidelines set by the different initiatives or groups listed in the appendix.The article should be submitted w ith tw o separate fi les,one w ith detailed information about authors and the title,short running title,source of the work,in addition to the names,address,telephone and fax number or E-mail address for the corresponding author.Another fi le should show only the title,running title,abstract,main text,tables,fi gures of the submitted article as w ell as a list of references,w hich w ill be sent to review ers.

Thetitleof the paper should be chosen w ith care:a short one has more impact and may be expanded by a subtitle.

Structuredabstractof original articles should include four sections as Background,Methods,Results and Conclusions and have no more than 300 words summarizing the most important points in the article,incorporating key w ords suitable for electronic retrieval systems.Background:This section should provide a precise statement of the primary focus of the study and the context in w hich it w as carried out.Methods:This section describes how the study was performed,including details of clinical and/or technical procedures.Results:This section describes the salient results of the study.Conclusions:This section covers conclusions and their clinical application or others,w hile equal emphasis should be given to positive and negative fi ndings of equal scientifi c merit.

Introduction:This should explain the problem w hich is to be addressed,w ith a defi nition of the hypothesis to be examined if appropriate,out-lining,briefl y,its relevance to the appropriate literature.
