Objective To analyze the clinical performance of hepatitis C virus antibody detection by bi-direetional lateral flow method and evaluate whether the bi-directional lateral flow method is suitable for clinical use.Methods Four hurdred and nineteen samples were collected and tested anti-HCV antibodies with hi-directional lateral flow and CMIA kits.These samples contain:107 patients with confirmed hepatitis C virus infection,162 patients with other diseases than hepatitis C virus infection and 150 healthy controls.Two positive reference materials for ELISA were tested at the same time.The testing results were analyzed with statistical methods.Results Compared with RIBA,the sensitivity and specificity of bi- directional lateral flow method were 98.1% and 99.7% respectively,the agreement rate with CMIA was 99.0%.The reproducibility percentage of the+/-20% at the cutoff concentration were 97% and 99% respectively.No crossing reaction with hepatitis A/B/D/E virus infection and HIV-1/2 positive individuals were found in the tests.Conclusion The hi-directional lateral flow method for HCV detection shows good clinical performance and is suitable for clinical use.

ObjectiveTo investigate the prevention and treatment of pneumonia in patients with acute cervical spinal cord injury (CSCI).MethodsData of 278 patients with acute traumatic CSCI admitted from 1988 to 2004 were analyzed retrospectively.Results Pneumonia was the major complication following acute CSCI and discovered by radiography during the first 3—33 days after injury. The all cases were nosocomial pneumonia and G- bacilli were main pathogens, particularly pseudomonas aeruginosa. The incidence of pneumonia of patients with score ≤6 according to the criteria of American Spinal Injury Association (ASIA) was significantly higher than those with ASIA score >6 (P<0.001).ConclusionThe high incidence of pneumonia in the CSCI is associated with the level and completeness of the injury. The G- bacilli causing nosocomial infection are main pathogens.

Objective To study the relationship between bcl-2 , Fas and Fas ligand (FasL) and the role of them in the pathogenesis of systemic lupus erythematosus (SLE). Method Flow cytometry was used. Results Apoptosis of peripheral lymphocytes was significantly increased in SLE patients than that of normal controls(P

Citing the IT development of the General Hospital of Nanjing Military Region at Fuzhou as an example, the authors point out that emphasizing the role of the people and doing a good job of talent planning and cultivation is the key to the IT development of a hospital. They argue that a hospital must have leaders and managers that stress the IT development of the hospital; it must have a team of people with high IT expertise; it must have a large number of staff very familiar with the operation of the computer; and it must be able to integrate its human resources and give play to the overall efficiency.

Hyperhomocysteinemia is an important independent risk factor for cardio-cerebrovas- cular diseases.Studies in recent years have suggested that hyperhomocysteinemia is also an independent risk factor for vascular dementia and Alzheimer's disease.Mild vascular cognitive impairment is the prophase of vascular dementia.Mainly through the damage of vascular wall structure and its function,homocysteine may has correlation with mild vascular cognitive impairment.

Objective To investigate whether terminal QRS distortion on the electrocardiogram in acute inferior myocardial infarction could be as a standard for the infarct-related artery,through comparing to coronary angiography.Methods Fifty-seven patients with acute inferior myocardial infarction were enrolled,among which,the right coronary artery (RCA) occlusion (RCA occlusion group) was present in 29 cases,and left circumflex coronary artery (LCX) occlusion (LCX occlusion group) was in 28 cases.The changes of electrocardiogram was analyzed in 12 hours after the acute episode.Results The incidence of terminal QRS distortion in leads Ⅱ,Ⅲ,aVF in RCA occlusion group was 44.8%(13/29) and 39.3%(11/28)in LCX occlusion group,and there was no significant difference (P > 0.05).The incidence of terminal QRS distortion in leads V4R-V5R in RCA occlusion group was 17.2%(5/29) and 7.1%(2/28) in LCX occlusion group,and there was no significant difference (P > 0.05).The incidence of terminal QRS distortion in leads V7-V9 in RCA occlusion group was 6.9%(2/29),which was lower than that in LCX occlusion group[53.6%(15/28)],and there was significant difference (P < 0.05).For identifying LCX as the infarct-related artery of acute inferior myocardial infarction,the sensitivity,specificity,positive and negative value in terminal QRS distortion in leads V7-V9 were 53.6% (15/28),93.1% (27/29),88.2% (15/17),67.5% (27/40).The area under curve of terminal QRS distortion in leads V7-V9 in identifying LCX as the infarct-related artery of acute inferior myocardial infarction was 0.733 (95% CI 0.599-0.868).Conclusion Terminal QRS distortion in leads V7-V9 may be of diagnostic value in identifying the infarct-related artery in acute inferior myocardial infarction.

Objective To investigate the effect of diagnostic ultrasound on cochlear hair cells in fetal guinea pigs. Methods Diagnostic ultrasound was used to irradiate the uteri of early pregnant guinea pigs(the first 15 days of gestion) and late pregnant guinea pigs(the 40th to 45th days of gestion) for 5 minutes daily. The number of cochlear hair cells in fetal guinea pigs was calculated using succinic dehydrogenase (SDH) staining, and computer image analysis system. The morphological change of cochlear hair cells was observed with scanning electron microscope(SEM). Results Compared with non-exposed control group, the number of total hair cells obviously decreased in the two exposed groups (P
