Clinical analysis of 128 patients with the fever of unknown origin / 中华传染病杂志

Objective Analysis of the etiological factors and the diagnostic methods of fever of unknown origin(FUO)in order to avoid misdiagnosis and missed diagnosis.Methods One hundred and twenty-eight patients with FUO were collected from our hospital.Results A final diagnosis was established in 118(92.2%)patients by using serological methods,bacteriological methods,body fluid test,bone marrow examination,tissue biopsy and diagnositic therapy.Infection(62.5%),connective tissue diseases(16.1%),malignancies(11.0%)were found to be the common causes of the fever in these patients while infection was the main cause of FUO in our research.The major pathogens responsible for the infec tion was bacteria,followed by virus and tuberculosis.Adult Still's disease was the most common connective tissue diseases in these patients.Lymphoma,malignant histocytosis and leukemia were the main forms of malignancy.Conclusion Infectious diseases was the most common cause of FUO while connective tissue disease and malignant tumors are also important in the pathogenesis of FUO.

Expression of anti-HBc single-chain variable fragment mediated by recombinant replication defective adenovirus in vitro / 中华肝脏病杂志

<p><b>OBJECTIVES</b>To define the expression of single-chain variable fragment (ScFv) against hepatitis B virus core protein (HBc) mediated by recombinant replication defective adenovirus carrying the anti-HBc ScFv gene in vitro and to define the activity of anti-HBc ScFv combining HBcAg.</p><p><b>METHODS</b>The recombinant adenoviruses carrying anti-HBc ScFv gene generated by homologous recombination in bacteria and packaged in 293 cells were transfected into HepG2 cells, and the anti-HBc ScFv was detected using SDS-PAGE and Western blot.</p><p><b>RESULTS</b>Green fluorescent protein (GFP) was observed in HepG2 cells after the transfection. SDS-PAGE displayed a protein strap about 2.7 x 10(4), and the result of Western blot displayed a positive reactive strap.</p><p><b>CONCLUSION</b>Anti-HBc ScFv can be expressed in cells mediated by recombinant replication defective adenovirus carrying the anti-HBc ScFv gene.</p>

The analysis of epidemiological and clinical characteristics of 112 cases patients with adult-measles / 中华传染病杂志

Objective To analyze the clinical data of 112 patients with adult-measles in the Af- filiated Shanghai Sixth People's Hospital and Third People's Hospital of Shanghai Jiaotong University from January to June in 2005,and to evaluate the epidemiologieal and clinical characteristics of adult- measles.Methods To retrospectively analyze the clinical data of 112 patients with adult-measles. Results Totally,112 measles patients were involved in this study,with male 63 and female 49 re- spectively.The gender rate was 1.3:1,average age about 32 years and the proportion of non-resi- dents was 40.18%.The peak of the incidence of disease emerged in April and May,and the positive rate of measle virus IgM antibody in serum was 96.43%.There were 97 patients(86.61%)who had the fever that beyond 39℃and 36 patients(32.14%)who had measle caused viral hepatitis.Conclu- sions There is a trend that the ages of patients that suffered from measle were postponed and the in cidences of disease are increased year by year,which maybe related to the nonstandard inoculation of measle vaccine,or the decrease of IgM antibody levels and so on.Meanwhile,serious toxemie symp- toms and liver damage can be observed.
