Objective To investigate infectious complications and analyze their risk factors in patients with systemic lupus erythematosus (SLE) and provide clue for antibiotics treatment. Methods Patients with SLE admitted to our hospital between 2002 and 2007 were. reviewed, and the characteristics of their infections including the infection sites, pathogens and the drug resistance of pathogenic bacteria were investigated. The suspected risk factors of infections in patients with SLE were selectod and then analyzed by chi-square test and Logistic regression. Results The prevalence of infection in this group of patients was 24.4% (130/533). One patient died from respiratory tract infection. The common infection sites were respiratory tract (56.9%), urinary tract (23.8%) and skin (18.5%). Bacteria were the most common pathogens of infections in SLId pa-tients (53.3%), the majority of which were gram-negative bacteria. The second major pathogen was fungus (39.2%), and the third was the combination of bacteria and fungus. There were 7 patients with tuberculosis. The common strains causing infections in SLE patients were. Escheriehia coli, Klebsiella pneumonea, Pseu-domonas aeruginosa, Staphylococcus aureus and Candida albican. Antimicrobial susceptibility tests showod that the drug resistant rates increased rapidly. The gram-negative ones were sensitive to eefoperazone-sulbac-tam and carbopenems. The infection-related risk analysis suggested that the independent risk factors of infections in SLE patients included old age, hypopruteinemia, moderate anemia and high dose of eorticos-teruids treat-ment. Conclusion Those patients with infection-related risk factors should be monitored closely for infec-tions. Respiratory tract and urinary tract are the most common infectious sites in SLId patients, and gram-nega-tive bacteria are the major pathogens, so antibiotics such aa cefoperazone-sulbactam or carbopenems may be good choices before the result of antimicrobial susceptibility test information is available.

Objective To analyze the features of intracranial epidermoid cyst on CT and MRI imaging.Methods 26 patients with intracranial epidermoid cysts proven pathologically were examined with pre-and post-contrst enhanced CT and MR imging,and 6 of 26 cases undergone CT plain scan.CT and MR imaging of 20cases were retrospectivelly reviewed.Results Among 26 cases,16 were located in the cisterns of cerebell opontine angle,7 in saddle area.2 inside of the skull;1in the brain essence.On CT,25 cases were homogeneous hypodense,one case was promiscuous high density,16 cases demonstrted inhomogeneous hypointensityimaging on T1WI,and inhomogenous hyperintensity on T2WI.4 cases display inhomogeneous signal.No contrast enhancement was noted except 2 cases with slightly periphery enhancement.One case brain organization receives invades,There was edema around tumor.17 cases demonstrated slightly inhomogeneous hyperintensity on FLAIR MR images,3 cases obviously advance.Conclusion The CT and MRI features of intracranial epidermoid cysts were certain characteristic,and MRI played an important role.as to uncharacteristic epidermoid cyst,there is still space for further research.

Objective To investigate the effect of mesenchymal stem cell(MSC) on the balance of Th1/ Th2 with different stimulations.Methods To inoculate MSC in 24-well tissue culture plates.after 3 days, added T lymphocytes co-stimulated by PMA and Ionomycin,or the MSC were added to the two-way mixed lymphocyte culture according to different proportion.The subsets and cytokines of T lymphocytes were analyzed by flow cytomety.Results Differentiation into Th1 of T lymphocytes activated by co-stimulation can be inhibited MSC;In MLC,CD8~+T cell subsets and Th1 were evidently decreased.But Th2 cells were slightly increased.Conclusion MSC can significantly suppress CD8~(+)T cell,Th1,increase Th2.MSC has potentialities of alleviating acute graft-versus-host disease(aGVHD) and maintaining graft versus leukemia(GVL).

Literatures on arrhythmia induced by acute organophosphorous pesticide poisoning published in domestic journals from 1979 to 2010 were searched. Total 3468 cases of acute organophosphorous poisoning were collected and analyzed. The average abnormal ECC rate was (53 ±15)%(35. 4% -68. 4% ) in acute organophosphorous poisoning, the most common ECG abnormalities were ST-T segment changes (26. 5% ) and sinus tachycardia (16. 6% ). The rate and severity of ECG abnormalities were increased with the severity of organophosphorous poisoning(x2 = 33. 253,P < 0. 01). The most common causes of death in acute organophosphorous poisoning were ventricular tachycardia and ventricular fibrillation (26.2%).

Objective To study the renal oncocytoma CT eosinophil performance,improve the rate of correct diagnosis.Methods Retrospective analysis of seven cases confirmed by pathology of renal oncocytoma CT.Results Tumor cortex to the growth mainly three cases to the pelvis grow mainly two cases,two cases are located entirely within the renal parenchyma.Plain;Four cases of tumor performance for the more homogeneous density.Three cases density uniform,which show two cases within Stelletta tenui Lindgren-sharp edge,low-density,one cases show multiple internal circular low-density category,there calcification in 2 cases.Enhanced cortex and medulla period was more homogeneous strengthen four cases,three cases heterogeneous enhance and strengthen below the renal cortex.Pelvis period density decreased,but the level not lower than the same muscle density,and normal kidney tissue clear,two cases showed a complete fake capsule.Conclusions Renal oncocytoma scar except center outside homogeneous enhancement,pelvis with a period of not less than muscle density levels,and normal kidney tissue.Coated with a complete sham and center when scar more precise diagnosis.Other typical performance required when combined with clinical analysis.

Objective To study the content of interleukin- 6 (IL-6) and the altering pattern of erythrocyte immunity and T cell subgroup in the blood of outer circulation in the patients with cerebral glioma, and to expl ore their relationship and the clinical significance. Methods Enzyme linked immunosorbent assay (ELISA) was used to determine the content o f IL-6. The immunoabsorption was employed to examine the erythrocytic immune ac tivity and its regulatory function. Streptavidin-Peroxidase (S-P) was used to determine the cell number of CD3 (cluster of differentiation 3), CD4, CD8. Results The content of IL-6 in the group with cerebral glioma i s significantly lower than that in the control group (P0.05). Conclusion The weakening of immune function is obse rved in the patients with cerebral glioma. Testing of the content of IL-6, eryt hrocyte immunity and the activity of T subgroup has important clinical significa nce in the occurrence, development, treatment, outcome and prognosis of the cere bral glioma.

This study was aimed to establish a fast determination method of main components in honey. Honey samples from difference production bases were used as study objects. Transmission and reflection spectra of different honey samples were collected with the Fourier transform near infrared spectrometer. The main components in honey (moisture content, fructose content, glucose content and reducing sugar content) were detected by the near infrared quantitative analysis technique. The near infrared quantitative analysis models of moisture content, fructose content, glucose content and reducing sugar content in honey were established by the partial least squares (PLS). The results showed that the correlation coefficient (r) of the moisture content, fructose content, glucose content and reducing sugar content in honey were 0.997 25, 0.973 90, 0.927 94 and 0.952 68, respectively. The root mean square error of prediction (RMSEP) were 0.165 (%), 0.564 (%), 1.300 (%) and 1.270 (%), respectively. It was concluded that determination of main components in honey by the near-infrared spectroscopy technology was a fast and nondestructive determination method with high accuracy, which can be used in the quantitative detection of main components in honey.
