Objective To study the influence of Qingzao Runfei Huazhuo Xingxue decoction on pulmonary tissue and lung function in mouse model of lung injury induced by PM2.5, and to provide an idea of clinical prevention and treatment of respiratory diseases induced by PM2.5. Methods Totally 30 clean level male ICR mice were randomly divided into three groups: normal control group, model group and Qingzao Runfei Huazhuo Xingxue decoction intervention group, with 10 mice in each group. Model of PM2.5-induced respiratory disease in mice was reproduced by instilling nasal cavity drip PM2.5 suspension 40 mg/kg once a day for 6 weeks. In the treatment group, the mice were fed with the Qingzao Runfei Huazhuo Xingxue decoction twice a day from the 4th week of instilling PM2.5 suspension until the end of experiment. In the normal control group, the mice were fed as usual. At the end of the experiment, the total protein content in bronchoalveolar lavage fluid (BALF), and lung wet/dry weight (W/D) ratio was determined. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes in lung tissue under light microscope. The inflammatory mediators levels in lung tissue were determined by antibody-sandwich enzyme linked immunosorbent assay (ELISA). Results Respiratory system damage model was successfully reproduced by dripping of PM2.5 suspension in nasal cavity. Compared with normal control group, inflammatory changes and inflammatory cell infiltration in model group were significant, and lung W/D ratio (4.71±0.33 vs. 3.13±0.12), total protein content in BALF (mg/L: 363.98±18.24 vs. 82.13±12.78), tumor necrosis factor-α [TNF-α (ng/L): 185.72±0.23 vs. 31.03±0.16], interleukin-8 [IL-8 (ng/L): 531.85±37.83 vs. 72.64±16.72], and leukotriene B4 [LTB4 (ng/L): 931.74±48.64 vs. 483.81±41.74] in lung tissue were significantly increased (all P < 0.05). Compared with the model group, the inflammatory changes of lung tissue in Qingzao Runfei Huazhuo Xingxue decoction intervention group were significantly reduced, lung W/D ratio (3.92±0.41 vs. 4.71±0.33), total protein content in BALF (mg/L: 213.21±19.62 vs. 363.98±18.24), TNF-α (ng/L: 124.15±0.27 vs. 185.72±0.23), IL-8 (ng/L: 238.42±35.82 vs. 531.85±37.83) and LTB4 (ng/L: 582.85±31.00 vs. 931.74±48.64) levels in lung tissue in Qingzao Runfei Huazhuo Xingxue decoction intervention group were significantly decreased (all P < 0.05). Conclusion Qingzao Runfei Huazhuo Xingxue decoction can improve PM2.5-induced damage and pathological inflammatory changes in lung tissue, which provided some new ideas for the treatment of PM2.5-induced respiratory diseases.

Objective To detect the expression of Cytokeratin 19 (CK19) and human mammaglobin (hMAM) mRNA in the peripheral blood of breast cancer patients dynamically and to evaluate its clinical significance.Methods The expression of CK19 and hMAM mRNA was evaluated by real-time fluorescent quantitative reverse transcriptase pelymerase chain reaction in the peripheral blood of 40 breast cancer patients and 10 healthy volunteers.Results The expression of CK19 and hMAM in the peripheral blood of 40 breast cancer patients were higher than healthy donors.The positive expression rate of CK19 and hMAM was descending tendency during treatment.The different staging expression rate had no differences between before treatment and during treatment,but after treatment the expression rate had remarkably differences (CK19:P=0.044;hMAM:P=0.005).If the expression of CK19 and hMAM was continual positive,the rate of recurrence and metastasis would be higher (P＜0.001).Coneluslons Real-time fluorescent quantitative RT-PCR may detect the expression of CK19 and hMAM in the peripheral blood of breast cancer patients,and it is a sensitive and specific technique.The resuits suggest a possible use of this approach for evaluating prognosis,monitoring recurrence.

Objective To clone, express Tp0319 gene from Treponemapallidum (T. pallidum), and to assess the immunocompetence of recombinant protein. Methods The immuno-dominant region of Tp0319gene was chosen by computer analysis, amplified from T. pallidum complete genome by PCR, subcloned into the expression vector pQE32 to construct a recombinant plasmid, pQE32/Tp0319, which was then expressed in E. coli M15. The recombinant protein was purified with Ni-NTA affinity chromatography, and identified by using sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE) and Western blot. New Zealand rabbits were immunized with the recombinant protein, and the titer of anti-Tp0319 antibodies in sera from immunized rabbits were measured with indirect ELISA. Also, indirect ELISA with the recombinant Tp0319 as coating antigen was performed to detect the anti-Tp0319 antibody in sera from 200 normal human controls and 200 patients with syphilis. Results The prokaryotic expression vector pQE32/Tp0319 was constructed successfully, and the recombinant protein Tp0319 with a molecular weight of about 30 000 was attained. Specific humoral response was elicited by the recombinant protein in New Zealand rabbits and the specific antibody titer was more than 1: 10 240 after immunization for 3 times. Western blot proved that the recombinant protein could specifically react with anti-T. pallidum IgG antibody-positive sera. Indirect ELISA was successfully developed with the recombinant Tp0319, and detected antibodies to T. pallidum in control sera with a sensitivity and specificity of 100% (40/40), respectively. Compared with T. pallidum particle agglutination (TPPA) assay, the sensitivity and specificity of the indirect ELISA were 92.6% and 100%, respectively, in the detection of T. pallidum in sera from patients and controls, and the concordance between the indirect ELISA and TPPA was 96%. Conclusions The prepared recombinant protein shows a satisfactory immunocompetence, which may lay a foundation for its further application in the serodiagnosis of syphilis.
