Objective To discuss the applied value of multislice CT scan in combination with 99 MTC -MI-BI -SPECT for the diagnosis of isolated pulmonary nodule lesions.Methods 60 patients with solitary pulmonary nodules shadow in the X -ray film from July 2014 to August 2015 in our hospital were selected and detected by spiral CT scanning and 99mTC -MIBI -SPECT imaging.Scan results and pathological examination or surgery were com-pared,specificity,sensitivity and accuracy of pulmonary nodules were concluded about the method in the differential diagnosis isolation.Results The specificity,sensitivity and accuracy of multislice spiral CT scanning alone were 73.6%,78.2%,79.3% respectively;The specificity,sensitivity and accuracy of 99mTC -MIBI -SPECT imaging alone,were 82.6%,78.2%,79.3% respectively;The specificity,sensitivity and accuracy of multislice CT scan com-bined with 99mTC -MIBI -SPECT imaging were 93.3%,93.2%,93.8% respectively.The accuracy of combined detection was significantly higher than that of 99mTC -MIBI -SPECT examination(χ2 =6.783,P =0.010)or CT scan (χ2 =8.012,P =0.008).Conclusion Multislice CT scanning combined with 99mTC -MIBI -SPECT imaging has better effect in diagnosing pulmonary nodule lesions,which is superior to the method alone.The combination meth-od can obviously improve the detection rate of lung nodule lesions,which is,worthy of further promotion.

Objective　To study the possibility of measuring health status for residents in rural areas by the Chinese SF-36 scale. Methods　Health status for 207 residents in rural areas of Fuyang city who were 14 years old and over was measured by the Chinese SF-36 scale. The reliability and validity were analyzed. Results　The internal consistency reliability coefficients (Cronbach'α) exceeded 0.50 for all scales except SF and RE scales. Inter-scale correlation coefficients were lower than Cronbach'α coefficients for all scales except SF scale. Factor analysis identified three principal components, which could be used to explain 64.6% of the total variance. The differences of scale scores between the young group and the middle age group weren't significant. There weren't significant differences of scale scores between sexes except RP scale. The differences of scale scores between smokers and no-smokers, drinkers and no-drinkers weren't significant. Nor were the differences between various educational levels. Conclusion　Whether the Chinese SF-36 scale is suitable for measurement of health status for residents in rural areas needs further studies to give more evidences.

Objective The TCS gene without N-and C-terminal sequences was cloned into pET-29b in order to get the recombinant trichosanthin(rTCS) at the relatively high level in E.coli,and the rTCS immunogenicity was compared with natural TCS(nTCS). Methods TCS gene without the N-and C-terminal coding sequences was amplified by RT-PCR,and then inserted into pET-29b.The soluble rTCS was induced with IPTG and purified through metal chelate affinity chromatography,the purity and content were showed by the thin-layer scan analysis and bradford assay.After the rabbits were immunized with purified rTCS and nTCS,respectively,the titer and specificity of polyclonal antibody were detected by indirect ELISA assay and Western blotting. Results 1.The vector pET-29b-TCS was constructed successfully after it was confirmed with the same restriction enzymes.2.The rTCS attained the maximum in the presence of 1 mmol/L IPTG for 4?h at 30℃.3.The soluble rTCS was expressed at relatively high level(36% of total protein in E.coli) and the yield of rTCS with a purity of 95% was 1.2?g in 1 L bacterium.4.The polyclonal antisera titer of nTCS was significantly higher than that of rTCS(1∶40?960 and 1∶5?120 respectively).5.The specific reaction between rTCS and anti-nTCS antibody was detected by Western blotting.Conclusion The high level expressing vector pET-29b-TCS,carrying TCS gene withoug the N-and C-terminal coding sequences,was constructed successfully.The immunogenicity of rTCS was remarkably lower than that of nTCS,which indicates that glycosylation of nTCS has a relationship with the antigenicity.

Objective To retrospectively analyse the efficacy and the influencing factors of plasma exchange(PE)in patients with chronic severe hepatitis.Methods Sixty patients of chronic severe hepatitis were included.Results The effective rate was 61.7%.The efficacy of PE was closely related to age,clinical stage,pre-treatment serum bilirubin values,prothrombin activity and incidence of complications(P0.05).Conclusion PE can significantly improve the survival of patients with chronic severe hepatitis.Especially for the patients under 60 years old,those with low serum TBIL level and high PTA,and those in the early clinical stage,PE treatment would achieve a better efficacy.But the improvement of prognosis of severe hepatitis still depends on the early specific treatment and active prevention of complications.
