ObjectiveTo evaluate the efficacy and safety of tirofiban in treatment of ST segment elevation acute myocardial infarction(STEAMI) no-reflow and acute thrombosis after emergency percutaneous coronary intervention(PCI). MethodsForty patients which were made definite diagnosis of STEAMI were intra-coronary artary injection fortirofiban after emergency PCI stenting occured no-reflow and acute thrombosis. First,the dose of 0.4μg·kg-1·min-1 was given from intra--coronary artary injection of tirofiban within three minutes, after 30min the dose were given 0.1μg·kg-1·min-1 for 48 hours. ResultsThe no re-flow and acute thrombosis was completely disappeared within five minutes,at the time,side effect with in one week was not observed. ConclusionsTirofiban treatment by direct injection in coronary arteries combined with emergency PCI, can increase the repeffusion rate of infarction related vessel in AMI patients,and improve TIMI reflow. This reperfusion method was effective and safe.

Objective:To prepare compound fluconazole gel and to establish a method for its quality control. Methods: Flucon-azole and baicalin were the main ingredients in the gel, and their contents were determined by HPLC. Moreover, the drug release in vitro, irritation and stability of the gel were tested. Results:The fluconazole and baicalin had a good linear relationship within the range of 12. 5-150. 0 μg·ml-1 and 25. 0-175. 0 μg·ml-1, respectively. The average recovery rate was 99. 45%(RSD=0. 40%, n=9) and 99. 31%(RSD=0. 31%, n=9), respectively. The in vitro drug release of the gel was accordance with the first order release e-quation, and the cumulative release rate of fluconazole and baicalin in 12 h was 87. 6% and 80. 03%, respectively. The gel was stable without irritation. Conclusion:The formula, preparation technology and stability of compound fluconazole gel are promising and the quality standard is controllable.

Objective:To determine the effects of Foxp3-overexpressing lung cancer cells on activated CD4+T lymphocyte.Methods: Stable Foxp3-overexpressing lung cancer cells NCIH-1299,NCIH-hFoxp3,was generated by transfection of NCIH-1299 cells with plasmid pcDNA3-hFoxp3 mediated by Lipofectamine 2000 and by selection with G418,and validated by quantitative PCR and Western blot.The expression levels of IL-8 and IL-10 secreted by NCIH-hFoxp3 and NCIH-control were measured by ELISA.IL-2 secrection by activated human CD4+T lymphocyte which was tested after stimulation with 20% conditioned medium of NCIH-hFoxp3 and NCIH-control cells.The proliferation of activated human CD4+ T lymphocytes was assessed by MTT after coculture with NCIH-hFoxp3 cells.The adhesive ability of activated human CD4+ T lymphocytes was probed with NCIH-hFoxp3 cells by immunocytochemistry.Results: Compared with NCIH-control cells,NCIH-hFoxp3 secreted high level of IL-10 and low level of IL-8.NCIH-hFoxp3 with Foxp3 overexpression significantly suppressed the proliferation,adhesive potential and IL-2 expression by activated CD4+ T cells.Conclusion: Suppression of immune activities of activated CD4+ T cells by Foxp3 overexpression in lung cancer cells may correlate with cytokine IL-8 and IL-10,which can contribute lung cancer progression.

Objective To investigate the expression of TIPE2 in splenic lymphocytes derived from the mouse model of cattle collagen Ⅱ-induced rheumatoid arthritis (CIA) and from peripheral blood of patients with rheumatoid arthritis (RA) for its role in the pathogenesis of RA.Methods The CIA mouse model was established by immunization of DBA-1/J mice with cattle collagen Ⅱ.Peripheral blood lymphocytes were collected from RA patients and healthy donors.The TIPE2 mRNA and protein expression in splenocytes of CIA and control mice were measured by semi-quantitative RT-PCR and Western blot,respectively.In addition,fluorescence quantitative RT-PCR and Western blot were used to determine the TIPE2 mRNA and protein expression in peripheral blood lymphocytes derived from patients with RA and healthy donors.Results Both mRNA and protein expression of TIPE2 were higher in splenocytes of CIA mice and lymphocytes of peripheral blood from RA patients compared with corresponding controls.Furthermore,the mRNA and protein expression of TIPE2 increased significantly in patients with active RA.TIPE2 expression were positively correlated with DAS28 scores (P＜0.001).Conclusion Our results suggest that TIPE2 plays a role in the RA pathogenesis.The level of TIPE2 may also indicate the severity of rheumatoid arthritis.

Objective To evaluate the value of quantitative 3T dynamic contrast enhanced MRI in the diagnosis of breast lesions. Methods One-hundred and eighteen patients suspected of breast lesions underwent MRI examination. A 3.0 T MR scanner was used to obtain the quantitative MR pharmacokinetic parameters: Ktrans( volume transfer constant), Kep (exchange rate constant) and Ve (extravascular extracellular volume fraction). The mean Ktrans, Kep and Ve of malignant, benign and normal glandular tissues were calculated and compared each other using LSD method. Independent sample t test was used between invasive ductal carcinoma and ductal carcinoma in situ (microinvasion included). Finally, the areas under the ROC curve (AUC) of Ktrans, Kep and Ve between malignant and benign lesions were compared. Results The mean Ktrans, Kep and Ve of malignant lesions (n=87) were (1.010±0.580) min-1, (1.634 ± 1.481) min-1 and (0.735 ±0.273); the mean Ktrans, Kep and Ve of benign lesions (n=23) were (0.331±0.192) min - 1, (0.417±0.324) min - 1 and (0.847±0.291); and the mean Ktrans, Kep and Ve of normal glandular tissues (n =83) were (0.051 ±0.028) min-1, (0.133±0.125) min-1 and (0.597±0.354), respectively. There were significant differences between normal glandular tissues and benign lesions, normal glandular tissues and malignant lesions, benign and malignant lesions in Ktrans (t=9.681, 11.189, 5. 590, respectively, P ＜ 0. 01 ), normal glandular tissues and malignant lesions, benign and malignant lesions in Kep(t =5. 287, 3. 874, P＜0. 05). There were a statistic differences between normal glandular tissues and benign lesions, normal glandular tissues and malignant lesions in Ve(t =2. 932, 2. 562 ,P ＜0. 05). There were no significant differences between normal glandular tissues and benign lesions in Kep, benign and malignant lesions in Ve ( t = 0. 760, 0. 832, P ＞ 0.05 ),invasive ductal carcinoma and ductal carcinoma in situ (microinvasion included) in Ktrans, Kep and Ve(t =0.834,0.075,0.454,P＞0.05). The areas under the ROC curve (AUC) of Ktrans, Kep and Ve between malignant and benign lesions were 0. 934, 0. 941 and 0. 659. The sensitivity of Ktrans, Kep and Ve were 77.01% ,91.95% ,56. 32% and the specificity of Ktrans, Kep and Ve were 95. 65%, 86. 96%, 78.26% for the differential diagnosis of breast lesions if taken the maximum Youden's index as cut-off. Conclusion The differential diagnosis of benign and malignant breast lesions by Ktrans, Kep is applicable.
