The sensor of naringin(NG), a non-electroactive substance, was prepared based on the molecular imprinting technique.Using cyclic voltammetry technique (scan rate is 100 mV/s), the naringin imprinting sensitive film, poly-o-aminophenol was coated on the surface of a graphite electrode in the presence of naringin which was considered as the template, and characterized by SEM and X-ray reflective spectrophotometry (XRR).Using K_3Fe(CN)_6 as an electroactive marker, the electrochemical properties of the NG sensor were investigated by CV, electrochemical impedance spectroscopy (EIS), differential pulse voltammmetric and chronoamperometric.The results showed that the imprinted electrode was significantly different from the non imprinted electrode in morphologies and electrochemical properties, and a linear relationship between the peak current and the naringin concentration was found in the range of 6.0 × 10 ~(-5)-1.4 × 10 ~(-4) mol/L with a detec tion limit of 1.6 × 10 ~(-5) mol/L.Moreover, the imprinted electrode exhibited a good selectivity and rapid response to the naringin template molecules, as well as an excellent reproducibility(RSD = 1.8 %, n=5).

Objective To investigate the changes of brain volumes in neuromyelitis optica (NMO)patients using voxel-based morphometry (VBM) method, and preliminarily explore the pattern of cerebral anatomical impairment. Methods Twenty-three clinically defined NMO patients and 15 gender and age matched healthy volunteers underwent 3-dimensional (3D) fast spoiled gradient echo (FSPGR) sequence scanning on 3.0 Tesla MR systen. Raw data was processed and analyzed using statistical parametric mapping (SPM) 5. Whole brain volumes included grey matter volume (GMV), white matter volume (WMV), total intracranial volume (TIV), grey matter fraction (GMF), white matter fraction (WMF),brain tissue fraction (BTF) and regional brain volumes between the two groups were compared by independent samples t-test and an Pearson were performed to compare the regional brain volumes and the ages. Results GMV of NMO group[(610. 2 ± 55.0) ml] was significantly decreased comparing to healthy control group[(657. 2 ± 36. 3) ml] (t = - 2. 915, P ＜ 0. 05). The age of NMO patients [(40 ± 9) years old] showed negative correlation with GMF [(42. 5 ± 2. 6) %] (r = - 0. 673, P ＜ 0. 05). Regional brain volume analysis showed decreased GMV in left insula and bilateral posterior cingutates in NMO patients,while decreased WMV was found in left frontal and left parietal white matter. Conclusion VBM could detect brain volume changes sensitively. Total grey matter volume in NMO patients was decreased comparing to HC group. Regional grey matter atrophy in NMO patients occurred in left insular and bilateral posterior cingutates, regional white matter atrophy occurred in left frontal and left parietal lobe.

Objective To evaluate the changes of physical activity status of residents in Beijing Yayuncun(Asian Games Village)Community.Methods A total of 1765 permanent residents over 15 from 600 families living in Yayuncun Communities since 2000 were selected in this prospective study.Thebaseline survey was carried out with the Questionnaire for Residents of Beijing Typical Community in 2004 and 2005.From 2006 to 2008,same questionnaire was used for the follow-up survey,and 1412 residents were responded to the questionnaire.Results The knowledge levels related to physical exercise of Yayuncun residents elevated(P＜0.01).The source of knowledge gain from Olympics Games promotion,specialized community lectures and intemet increase significantly(P＜0.01),that from other media decreased(P＜0.01).The exercise rate in community was higher than in other sites(P＜0.01)and increased significantly (P＜0.05);while doing exercise in charged sites decreased(P＜0.05).Logistic regression analysis showed that regular physical exercise was related to age,BMI,exercise-related knowledge,exercise sites,attitude for sport facilities and chronological order.Conclusion During the preparation for the Beijing Olympic Games.the status of physical exercise of residents in Yayuncun Community presented the positive trends.

Objective To investigate the infection sites,the offending species,diagnosis and prognosis of deep fungal infections (DFI) in patients with systemic lupus erythcmatosus (SLE).Methods Fifty-one patients with fungal infections in 1466 SLE patients admitted to Peking Union Medical College (PUMC) Hospital from 2000 to 2006 were reviewed retrospectively.Results Candida albicans was ranked the first pathogen,followed by ncoformans and Aspergillus species.The infection sites were lungs,cerebral meninges and blood in the order of prevalence.The overall mortality was 20%(10/51).Aspergillasis carried the highest mortality which couht be as high as 80%.Hypoproteinemia,multiple focus of fungal infections,Aspergillasis and fungemia might he the independent risk factor for mortality.Conclusion Candida albicans is the most frequent species of fungal infections in SLE patients.Iungs are the most prevalent location of infection.Earlier diagnosis is important.Special attention should be paid to aspergillasis.

Objective: To study whether domestic chloramphenicol eye drops with different ethylparabenin content meet the re-quirements in Chinese Pharmacopoeia. Methods:Antimicrobial effect test was used to examine the antimicrobial effect of the different eye drops. Results:The antimicrobial effect of the eye drops was in compliance with the requirements in the pharmacopoeia. Conclu-sion:The ethylparabenin concentration in the eye drops is higher than necessary. Boric acid and borax not only can adjust pH, but also show antimicrobial effect.

Objective:To investigate the content rationality of antimicrobial agent thimerosal in chloramphenicol eye drops. Meth-ods:Chloramphenicol eye drops with thimerosal at different concentrations were prepared, and the antimicrobial activity was studied. Results:When the test solution contained 0. 02 mg·ml-1 thimerosal, the antimicrobial activity could achieve the requirement in the pharmacopoeia. Conclusion:Thimerosal at different concentrations in the commercial chloramphenicol eye drops all can reach the anti-microbial effect. However, the thimerosal concentration in some eye drops is unreasonably high, which should be reduced.
