Objective To investigate the value of combined detection by using tumor markers cytokeratin‐19 fragment antigen (CYFRA21‐l) ,neuron‐specific enolase (NSE) ,carcinoembryonic antigen (CEA) and carbohydrate cancer antigen 125(CA125) in lung cancer diagnosis .Methods 200 people who treated in the hospital in related departments from January 2012 to January 2014 were enrolled in the study .100 of them suffered from lung cancer ,53 suffered from benign lung disease ,the rest 47 were healthy people .Electrochemiluminescence method or enzyme‐linked immunosorbent assay(ELISA) were used to detect serum tumor mark‐ers CYFRA21‐1 ,NSE ,CEA ,CA125 and the sensitivity ,specificity and accuracy of different combinations of test items were evalua‐ted .Results In the single detection of those tumor markers for the diagnosis of lung cancer ,CYFRA21‐1 detection got the highest sensitivity and accuracy ,while CA125 got the highest specificity(95 .0% ) .The sensitivity and specificity of combined detection were both significantly higher than single detections .The sensitivity ,pecificity and accuracy of the combined detection of the 4 tumor markers were 92 .0% ,72 .0% ,and 87 .0% respectively .Conclusion In the clinical diagnosis of lung cancer ,the combined detection of several serum tumor markers get higher sensitivity and accuracy than single detection ,which is worthy of clinical promotion .

Objective To investigate the academic level and influence of the Chinese Journal of Digestive Surgery from the point of articles published and the authors.Methods The articles and authors of Chinese Journal of Digestive Surgery from 2002 to 2012 were retrieved from the Wanfang database and the China National Knowledge Internet database.The full texts were browsed and saved,and then the data were input to Excel for bibliometric analysis.Results There were 1917 articles were published in the Chinese Journal of Digestive Surgery during the past 11 years,and the average number of articles per issue was 29.05.The rate of articles with funded projects was 30.62％,and the citation rate was 58.52％.Authors were from 32 provinces,municipalites and Hong Kong.The numbers of articles contributed by authors from Chongqing,Beijing and Shanghai ranked top 3,which were 446(23.27％),240(12.52％) and 203(10.59％),and followed by authors from Sichuan,Jiangshu and Guandong.The number of articles from affiliated hospitals of Medical Schools was 1382 (72.09％).The cooperation rate was 4.37,and the coauthor rate was 90.03％.Conclusions Chinese Journal of Digestive Surgery is an academic journal with high quality and strong influence.The distribution of authors of the Chinese Journal of Digestive Surgery is wide,and the cooperative rate of authors is high,while the distribution of authors is disproportionate.

Objective Imaging and clinical manifestations of melioidosis were analyzed in order to improve our understanding of the disease and to reduce the rate of misdiagnosis.Methods From 2001 to 2006,12 melioidosis cases were confirmed by blood,pus and sputum culture.All cases were examined with radiography,and nine of them with CT and 2 with US.The imaging and clinical data were assessed retrospectively.Results Ten of 12 cases revealed lung abnormalities,the main organ involved by melioidosis in the body.The appearances were observed as follows:diffused sheets and sheets fused partly in bilateral fields of the lungs can be seen on chest radiograph;homogeneous dense shadow of the lobe or segment were observed on plain chest film and CT;blurred strips radiated from hilum were revealed on plain chest film;multitude nodules in 2 lungs showed on CT;cavity with air and liquid be seen on plain chest film and CT;patches and granules in superior and middle fields or(and)inferior fields be seen on plain chest film and CT;arc shadow of water attenuation in dorsal thorax showed on CT.Infections outside the lung can be observed in orbital,lumbar muscle,liver and spleen in 1 case,and thighbone osteomyelitis with multi abscesses in one case.Conclusion Alhough medioidosis has no characteristic imaging appearances,the disease's location,extent,severity and quantity objectively can be demonstrated by imaging,final confirmation is necessary using the culture of blood,pus and sputum.

OBJECTIVE To probe cleaning methods of reusable puncture needles and improve the quality of cleaning. METHODS The 200 sets of puncture needles with blood were divided into two groups (groups A and B). Ultrasonic cleaning was used in two groups,but in group A was with 3% hydrogen peroxide solution and in group B with 1∶150 low foam multi-enzyme cleaning liquid for 20 minutes,after rinsing,the group A used 95% ethanol 2 ml/piece for dry,but the Group B used 90 ℃ 30 min,and then the bacterial endo toxins and 3% hydrogen peroxide tests,the cost of cleaning was compared. RESULTS The positive rates of the bacterial endo toxins and 3% hydrogen peroxide test in group A were conducted,at last were 6% and 5%,while group B all were negative (?2=6.19,5.13,P

OBJECTIVE To improve the management quality by discussing the usage of "Five Regular Methods" in hospital′s Sterilization Supply Center.METHODS The "Five Regular Methods" managment model into the following aspects of quality,service,safety,efficiency,people′s competency and environment was introduced.RESULTS After 6 months implementation of the model the efficiency and quality of service improved significantly.The environment became clean and shiny.Objects were put on their right place. And we realized the right integration in time and space for people,objects and places.CONCLUSIONS The "Five Regular Methods" is a set of perfect guidance for quality management.It is a management system by providing guidance from inside to outside,people to objects,soft ware to hard ware,theory to practice and rules to process.It is a good method for enhancing the service quality from all aspects.

Clinical data of granulomatosa cheilitis of 33 cases were analysed.Odontogenic infectious foci were found in each patient.Elimination of odontogenic infectious foci was followed by regression or disappearance of the swellings in all the 33 cases,suggesting a close relationship between granulomatous cheilitis and odontogenic infectious foci.Elimination of odontogenic infectious foci can be an important measure for the treatment of granulomatous cheilitis.

Since the teaching and research of sexual medicine in our country is conducted for not a long time,the available materials and information about it are not enough.In order to improve the quality of sexual medicine teaching and accumulate teaching experience,based on the teaching practice of sexual medicine in our school in the past,a brief summary and analysis about the teaching purpose,subject design,and the teaching method and effect of sexual medicine in our school are reviewed in the present article.

According to the changeover of modern medical teaching mode and the undergraduates' need of knowledge structure,we started the course Sociology of Sexuality in our university.In more than 3 years teaching experience and exploration,we arranged the content for each part of each chapter based on the teaching outline,teaching scheme and the students' knowledge and ability structure.As to teaching method,we adopted multimedia computer instruction,heuristic instruction,interactive instruction,participating teaching and audio-visual digital teaching method and so on.We are to introduce such a teaching means of exchange communication,and such an examination method combined with the traditional test as well as testing the capability of handling the actual problem,which can help to implementing the teaching work for Sociology of Sexuality.
