Objective To study the effect of nasal endoscopic radio frequency in the treatment of concealed epistaxis. Methods A total of 50 cases of concealed epistaxis underwent nasal endoscopic radio frequency in this department between October 2000 and October 2003. Results Of the 50 cases, 35 were cured and 12 improved by cauterization on one session, and 3 were cured by repeated cauterization, the total effective rate being 100%. Conclusions Nasal endoscopic radio frequency for concealed epistaxis has advantages of accurate position location and low costs.

Editorial ethical issues gained an increasing attention in this dynamic and diversity society.It is therefore necessary to examine the ethical principles,codes of conduct,responsibilities,and obligations involved in the editorial work for science and technology journals,in order to maintain a positive public image of the editors.

The knowledge economy development depends on knowledge and innovation.Prime Minister,Keqiang Li,proposed that the development of Internet + action plan in the government's report of the Twelfth National People's Congress third meeting of,which made the whole China's Businesses animate.In such rapid development situation in terms of big data,cloud computing,Internet +,and other modern technology,integrate Internet resources,transfer big data into required da ta after analysis,change the magazine service mode,then promote clinical science and technology magazine to make it more humane-oriented as well as satisfy the need of each reader.This study proposed certain ideas on the development of the Internet + and medical technology magazines.

Objective To evaluate the value of low dose multilayer spiral CT (MSCT) threedimensional reconstruction in diagnosis of children tracheobronchial foreign body.Methods Forty-three children with tracheobronchial foreign body which was confirmed by fiberoptic bronchoscopy were enrolled,and all of the children underwent low dose MSCT three-dimensional reconstruction.The volume data were reconstructed on work station (Siemens) with the techniques of multiple plane reformation (MPR),curved planar reconstruction (CPR),minimum intensity projection (MinIP),volume rendering (VR),CT virtual bronchoscopy (CTVB),and the results of MSCT were compared with fiberoptic bronchoscopy.Results The fiberoptic bronchoscopy results were used as the localization and qualitative diagnosis results.Locations of the foreign body were trachea and bifurcation of trachea (6 cases),right bronchus (23 cases) and left bronchus (14 cases),and the coincidence rate of localization diagnosis of MSCT was 100％ (43/43).Natures of the foreign body were nuts in 21 cases,beans in 5 cases,corn in 2 cases,fruits and vegetables in 6 cases,and other kinds in 4 cases.Qualitative diagnosis by MSCT was medium density foreign body,and the coincidence rate was 100％ (38/38).Five cases had bone mass,qualitative diagnosis by MSCT was high density bony foreign body,and the coincidence rate was 5/5.In 43 children,MPR (CPR) showed 41 cases (95.3％),CTVB showed 33 cases (76.7％),MinIP showed 34 cases (79.1％),VR showed 23 cases (53.5％),and axial scan showed 21 cases (48.8％).MPR (CPR) in showing foreign body rate was higher than other several postprocessing methods,and there were statistical differences (P ＜ 0.05).There was no statistical difference in the showing of foreign body between CTVB and MinIP (P ＞ 0.05),but CTVB and MinIP were higher than VR and axial scan,and there were statistical differences (P ＜ 0.05).Conclusions Low dose MSCT three-dimensional reconstruction is satisfactory in the diagnosis of children tracheobronchial foreign body.It can accurately evaluate the exact size,location,shape and pulmonary complications of foreign body,thus it plays an important role in the diagnosis of suspicious tracheobronchial foreign body.

The rapid development of Internet offers a new place for public opinion exchange,which have become part of the frontier in the contemporary social management studies.Internet not only helps to facilitate information exchange and expanding the knowledge horizon,but also provides a platform to express opinions for public.It is a new norm for the public to engage online opinion discussions in the age of wide Internet coverage and raising number of Internet users.Medical opinion on the Internet,as a new platform for opinion exchange,becomes an important channel of information dissemination.Positive media expression and information may help to create a healthier environment for the medical market and public relations.As a new topic in the field of medical studies,the analysis of opinions on medical services has gained importance among many medical intelligence agencies and journals.It may potentially help journals to understand the trend in public opinions and offers academics and technicians related up-to-date information.It is an innovative medical intelligence gathering and analysis method,and will have important implications.

With the development of 3G/4G mobile communication technology and the rapid growing Internet use,a variety of multimedia and media contents will be consumed on the phone,which potentially gives the population more opportunities to interact with media.Traditional paperbased journals can increase their influences by cooperating with the new media,like Weibo,mobile website/app.In the next decade,traditional journals and new media will likely to grow interdependencies instead of one being replaced by the other.If journals can utilize the strength of the new media through mobile websites/app or Weibo etc.,they could better serve for translational medicine.

Academic journal is the major channel for spreading science and technological advancement and it is also the main source of scientific information.We here introduce the experience of holding carefully designed lectures and seminars of Chinese Journal of Clinical Obstetrics and Gynecology.The topics were chosen to reflect the trend of the field and the features of the journal.The was proved an effective way to enhance the influence of the journal.

0.05 ). Conclusion FTY720 is an effective specific and reversible immunosuppressant.

Medical scientific journals play an important role in medical technology innovation and dissemination of scientific ideas.It is the main channel for medical academic communication,and also an important platform for translation of novel scientific ideas to clinical practice.Therefore,medical scientific journals needs to develop themselves to better serve the clinical practice,medical education and research,and to play a leading role in the innovation of information dissemination,to provide fast and convenient platform for medical communication,so as to accelerate the spread of medical technological achievements,and to promote the advancement of medical technology.

Academic Journals is an important carrier and source of the technology information. Establishing branding awareness is a critical to improvement of journals and a contemporary science and technology trend journal in science -technology field. Therefore, branding awareness is worthy to be emphasized.
