Objective To investigate the clinical effect of enzyme linked immunosorbent assay (ELISA) in detecting hepatitis C antibody. Methods 200 cases of patients with hepatitis C was measured by ELISA, the gold standard method for detection of hepatitis C virus antibody, recording the test results, the data input SPSS software to give the corresponding analysis and conclusions. Results 200 cases of patients with hepatitis C were successfully completed the gold standard method and ELISA method for detection of hepatitis C virus antibody, the analysis showed that positive rate of ELISA method for detection of hepatitis C virus antibody was significantly higher than that of the gold standard method, the positive rate of ELISA was 82.50％, the positive rate of the gold standard method for was 50.00％, results suggested that HCV detection rate of ELISA method is significantly better (P<0.05). Conclusion The method of ELISA can be used for the detection of hepatitis C antibody, which has positive significance in improving the diagnostic accuracy of hepatitis C, and is beneficial to protect the efficacy and quality of life of patients.

Objective To explore the effects of vaseline gauze combined with brain cotton piece on eye protection during otological surgery . Methods From January to March in 2015 , 80 patients with otological surgery were set as the experiment group , where vaseline gauze and brain cotton piece were used to protect eyes . From October 2014 to December 2014 , another 80 patients with otological surgery were set as the control group , where aureomycin eye ointment was used for eye protection . The two groups were compared in terms of complications incidence . Result The complication incidence of the experiment group was significantly lower than that of control group ( P < 0 . 01 ) . Conclusion Vaseline gauze and brain cotton piece can effectively protect the eyes for patients undergoing otological surgery , lower the occurrence rate of fewer complications and improve patients′comfort .

Objective To explore the effects of ulinastatin(UTI) on renal apoptosis and expression of bcl-2 in rats with severe acute pancreatitis(SAP).Methods Sixty rats weighing 250-300 g were randomized divided into 3 groups:pseudo-operation group(SO group,n=20),SAP group(n=20) and UTI treated group(UTI group,n=20).The model of SAP was established by retrograde injection of 5% sodium taurocholate solution into the biliopancreatic duct in the rats.Serum Cr and BUN were determined.The left kidneys were resected for light and electronic microscopic study.Renal cell apoptosis was determined by TUNEL.Expression of bcl-2 was detected by immunohistochemical staining of SABC.Results Serum Cr,BUN,renal cell apoptotic index and bcl-2 expression were markedly increased in SAP group compared with SO group(P

Objective To evaluate the feasibility and utility of three different assays on early diagnosis and monitoring of neonatal congenital cytomegalovirus infection. Methods Ninety-eight neonates whose mother was CMV-IgM positive during pregnancy were examined on the 14th days after birth for CMV antigen in blood and PCR-CMV-DNA in the saliva. Three different methods were applied including CMV antigenemia assay, PCR for CMV-DNA and ELISA for serum CMV-IgM. Neonates were followed up for six months. Results (1) Forty-eight of the 98 neonates were diagnosed as congenital CMV infection including 7 symptomatic infection and 41 asymptomatic. None of the 98 subjects was CMV-IgM positive. Among the 7 symptomatic cases, the positive rates of CMV antigen and PCR-CMV-DNA were 100%(7), 71.4%(5), and 70.7%(29/41), 46.3%(19/41) in the asymptomatic group, respectively. The sensitivity of CMV antigenemia assay and PCR was 75.0% and 54.2%, respectively. The CMV antigenemia index of the symptomatic cases was significantly higher than that of asymptomatic ones [(16-52)/50 000 vs (3-31)/50 000 white blood cells, P

Objective To summarize the ruptured types and surgical treatment experience for rupture of aortic sinus aneurysm. Methods Nineteen cases with aneurysm of aortic sinus were retrospectively analyzed. There were 10 cases with ventricular septal defect,6 cases with aortic valvular incompetence,6cases with other diseases,2 cases complicated by infective endocarditis. All cases underwent operational treatment. Results There were 15 cases of right aneurysm of aortic sinus,including 12 cases among them ruptured into right ventricle,3 cases rupture was penetrated into right atrium.There were 3 cases of null aneurysm of aortic sinus,including 1 case among them ruptured into right ventricle,2 cases ruptured into right atrium. There was 1 case of left aneurysm of aortic sinus, which ruptured into left ventricle. No operative death occurred in all, 1 case with aortic regurgitation light to moderate,and all cases were recovered.Conclusions The right aneurysm of aortic sinus is the most common types,and always rupture into right ventricle. It is important that aneurysm of aortic sinus should be operated as early as possible in order to avoid losing the chance of operation, particular in the patients complicated by infective endocarditis.

Returning astronauts had experienced decreased immune function and increased vulnerability to infection during spaceflights.In immune system,cell adhesion molecules(CAMs) play an important role in regulating immune response in normal physiological conditions.Studying changes of CAMs under microgravity could not only understand the effects of microgravity and its molecular mechanism on immune function,but also help to study the relative mechanism about cell sensation of microgravity.In this review,we will introduce some downstream signal pathways,gene expression and the effects on cell functions under microgravity.All of them are regulated by cell adhesion molecules related with the immune system.
