AIM To investigate the effect of aspirin on the proliferation and NOS expression in astrocytoma cell line, and probe into its mechanism. METHOD The effect of aspirin on the growth of astrocytoma cells was evaluated by MTT assay; NOS protein levels were determined by immunocytochemistry, NO and CEA concentration in the medium were determined by Griess assay and lepton catch immunising method respectively. RESULTS Aspirin inhibited the growth of astrocytoma cells, induced the expression of iNOS, increased the concentration of NO in the medium. The effects of these were centratoin dependent. Moreover, aspirin reduced the concentration of CEA in the medium. CONCLUSION Aspirin inhibits the growth of astrocytoma cell line. Up regulated iNOS expression resulting a increase of NO concentration are ascribed to mechanism of antiproliferation activity of aspirin. CEA is a good indicator in monitoring curative effect of astrocytoma.

Objective To prepare a novel fusion protein of hu3D3 and core-streptavidin(hu3D3/cSA) as a universal carrier targeting to lung cancer,and analyze its activities. MethodscSA gene was acquired by PCR,and inserted into plasmid hu3D3/pET-22b(+)to construct a recombinant plasmid hu3D3/cSA/pET-22b(+)．The fusion gene was expressed in E. Coli BL21(DE3).The fusion protein was purified through nickel-affinity chromatography column and renatured using TEA buffer. The tetrameric hu3D3/cSA complex was analyzed by SDS-PAGE and Western blot.The hu3D3/cSA protein was labeled with FITC,then its antigen-binding activity was analyzed using fluorescence microscopy,and the functional affinity of hu3D3/cSA and hu3D3 were analyzed and compared by flow cytometry. The biotin-binding activity of hu3D3/cSA was tested bv EUSA and Western blot. Results The recombinant plasmid hu3D3/cSA/pET-22b(+)with correct sequence was obtained. The fusion protein was found after expression in E. Coli BL21 (DE3)mainly in the form of inclusion body. After being purified and refolded,tetrameric complex was formed. The purified tetrameric hu3D3/cSA complex retained both antigen-binding activity of hu3D3 moiety and biotin-binding activity of cSA moiety:furthermore,the avidity of the hu3D3/cSA to its target antigen increased by about 14 times as compared with that of monomeric hu3D3. Conclusion The fusion protein hu3D3/cSA with both antigen- and biotin-binding activity is SHCCessfully prepared,and the avidity of hu3D3 moiety to 3D3 antigen is enhanced. Consequently,hu3D3/cSA could be a universal carrier targeting to lung cancer, and could be an alternative,convenient method to realize target therapy to lung cancer by the combination of multiple biotinylated anti-tumor drugs or agents.

Objective To investigate the status and associated factors of demand satisfaction (DS) of services for older adults with visual disability (OAVD).Methods Based on the 2nd National Sample Survey on Disability in 2006,a total number of 24 017 OAVD cases were included.Associated relationships among demographic,health-related,social,economic factors and services of DS,including health demand (Type Ⅰ),basic livelihood demand (Type Ⅱ),and environmental support demand (Type Ⅲ) were analyzed.Results The proportions of DS of Type Ⅰ,Ⅱ,Ⅲservices for OAVD were 35.1％,9.3％ and 4.3％ respectively.Eight factors as:having pension insurance (OR =1.64),living in urban areas (OR =1.54),per capita household income at ≥ 5 000 or over Yuan (OR=1.46) were favorable ones on OAVD DS while at age ≥ 80 or above (OR =0.90),being male (OR=0.93) were adverse factors of Type Ⅰ.Four factors as:being male (OR=1.43),living in urban areas (OR=1.15),subjects defined as grade Ⅱ (OR=1.36) and grade Ⅰ (OR=1.70)etc.,were favorable factors on OAVD DS.Five factors as:range of age groups at 15-59(OR=0.57)or at ≥60 (OR=0.45),per capita household income at 1 000-1 999 Yuan(OR=0.77),2 000-4 999 Yuan (OR =0.58) and ≥ 5 000 Yuan (OR =0.39) were adverse factors of Type Ⅱ.Factors as:living in urban areas (OR =1.23),defined as grade Ⅱ (OR =1.38) and grade Ⅰ (OR =1.34),having pension insurance (OR=1.62) and per capita household income at ≥5 000 Yuan (OR=1.42) etc.,were favorable factors of Type Ⅲ.Conclusion The DS degree of older adults with visual disability was generally very low while factors as:per capita household income,situation on social insurance,age,degree of disability,age when disability was identified,areas of residence,gender,grade of disability,marriage status,levels of education etc.,were significantly associated with the service on DS.

Objective To study the relationship between cleanliness of children′s hands and diminution of Ascaris lumbricoides infection. Methods Before the study all persons positive for ascaris eggs in the preliminary survey were treated with albendazole. Hand washing habit before meal and after defecation was kept in children of experimental group, but not in the control group. Kato thick smear stool examination was done once every two months for one year to compare the new infection rates in children without ascaris infection in the two groups, and the reinfection rates in the cured negative cases were also compared between them in half a month after chemotherapy. Results All the new infection rates as well as reinfection rates of each reexamination in the experimental group were significantly lower than that of the control group ( P

Objective: To establish a TaqMan-MGB probe-based real-time fluorescence RT-PCR assay for avian influenza H5N6 virus used in rapid diagnosis for suspected cases and surveillance for outer environment of live poultry markets. Methods: Based on the conservative sequences of avian influenza H5N6 virus for HA and NA gene published on GenBank, specific primers and TaqMan-MGB probes were designed to develop and optimize for the dual real-time RT-PCR assay. Specificity, sensitivity, repeatability and comparison tests were carried out. Results: This dual real-time RT-PCR detection can be completed within 80 minutes. There was no cross-reaction with other subtypes of influenza virus and common respiratory pathogens. The minimum detection limit could be up to 10 copies/reaction. The correlation coefficient of standard curve for the gene of H5 and N6 were 0.999 and 0.993, and the coefficients of variation for cycle threshold were range from 0.151%-0.549%and 0.213%-0.575%, respectively. The positive and negative coincidence rates of the validation test were 100%. Conclusions This TaqMan-MGB probe-based dual real-time RT-PCR for avian influenza H5N6 virus was rapid, specific and sensitive. It will have a good use in early emergency detection of suspected cases and continuous monitoring of external environment in live poultry trade market.

Objective To investigate the significance of computed tomography(CT)and 3.0 T magnetic resonance imaging(MRI)in intensity-modulated radiotherapy(IMRT)for esophageal carcinoma. Methods Thirty-five patients newly diagnosed with esophageal carcinoma who received radical radiotherapy in our hospital from November 2013 to April 2015 were enrolled as subjects. Target volume was delineated on the CT images and MRI images(T2-weighted and diffusion-weighted fusion images). The MRI-and CT-based IMRT plans were designed using the same dose prescription and dose constraints for organs at risk(OAR). The target volume,prescribed dose,and doses for OAR were compared between the two plans. Results In the two plans, dose distribution and planning parameters met the clinical requirement. The length of lesion,gross tumor volume (GTV),and planning target volume(PTV)defined by 3.0 T MRI were significantly smaller than those defined by CT(P=0.00,0.03,0.03). There were no significant differences in the D 2%,D 98%,D 50%,homogeneity index,or conformity index for primary GTV(PGTV)and PTV-PGTV between the two plans(all P>0.05). Compared with the CT-based plan,the 3.0 T MRI-based plan had a significantly smaller mean dose to the lungs and an insignificantly smaller actual dose to the lungs(P=0.00;P>0.05).There were no significant differences in maximum doses tolerated by the spinal cord or heart between the two plans. Conclusions In terms of target volume delineation and dosimetric parameters, both CT-and 3.0 T MRI-based plans meet the clinical requirement. The 3.0 T MRI-based plan may provide potential benefits for some OAR due to a smaller target volume compared with the CT-based plan.
