1.Analysis on the value of combined detection of CYFRA21-1,NSE,CEA,CA125 in lung carcinoma
International Journal of Laboratory Medicine 2016;37(8):1057-1059
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 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.

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.

Objective To investigate the relationship between the maternal nutritional stetus and the occurrence of intrauterine growth retardation (IUGR) with neonatal visual development disorder Methods Sixty pregnant women closed to expected date of confinement were randomly divided into 2 groups: IUGR and normal control group, each were with 30 cases Eight kinds of nutritional foods taken by the pregnant women were investigated and scored The vitamin A concentrations of maternal and umbilical blood were measured with fluorometer method The concentrations of iron, copper and zinc in maternal and umbilical blood were detected by spectrophotometer The results of examination with Flash visual evoked potentials (F VEP) were recorded by an experienced technician in neonates at 3~7 days after birth and 10 months after follow up Results Compared with the normal control, the IUGR group had taken less eggs, animal liver and fat pork during pregnancy ( 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.

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 investigate the disease causing gene of Stargardt disease. Method Fifteen patients with Stargardt disease were analyzed with 11 primers of the 11 exons of ABCR gene by using PCR SSCP and DNA direct sequencing techniques. Results Three newly detected disease causing mutations were found. Among those mutations, one is a frameshift mutation and others are single base transition. Conclusion This research confirmed that ABCR gene is associated with Stargardt disease, and 3 new mutations of ABCR gene were found.
