Objective: To investigate the expression of mage-a mRNA in lung cancer tissues of mice induced by coal tar pitch(CTP) fume and to discuss the above model for lung cancer immunotherapy with mage-a. Methods: Tumor tissue samples of lung cancer and paired non-tumor tissues were obtained from 8 lung cancer mice. Total RNA was extracted and cDNA was synthesized. Nested polymerase chain reaction amplification using mage-a specific primer was performed to detect the expression of mage-a. The 2 clones of mage-a mRNA positive PCR products were sequenced by DNAs sequencer (PE-377). Results: Of 29 mice in the experimental group, 8 were induced to lung cancer.Among which 5 (5/8) expressed mage-a mRNA. The expression of mage-a gene was not found in adjacent lung tissues. The DNA sequencing confirmed that the target gene fragments in 2 samples of PCR products were mage-a cDNA. Conclusion: The mage-a gene is highly expressed in lung cancer in mice induced by CTP fume, suggesting that CTP-induced lung cancer in mice may be an ideal animal model for lung cancer therapeutic experiment with MAGE-A.

Whether the sentinel lymph node (SLN) metastasis has important clinical significance for the therapy and prognosis of tumor. Sentinel lymph node biopsy (SLNB) has became the most accurate clinical method to confirm the status of sentinel lymph node. And the key of the success of SLNB is the localization of SLN. The methods used to locate SLN mainly are blue dye tracer method, radionuclide tracer technique, blue dye tracer method combined with radionuclide tracer technique, indirect lymphography, NIR imaging, and photoacoustic imaging. This article demonstrates the principle, application method and contrast agents of the indirect lymphography and the application in head and neck tumor.

The background,features,dimension and contents of 22 international appraisal tools for clinical guidelines were analyzed,and their history,evolution,rules and problems were described,in order to provide the evidence for developing appraisal tools for domestic clinical guidelines. In the study,it was found that the guideline evaluation tools have been classified and there is a constant strive to achieve the balance between comprehensiveness and practicability. But the existing evaluation tools are insufficient for clinical practical contents of guidelines. The scoring system should be improved. In addition,conflicts of interest,value choice and patients' involvement should be considered increasingly, and should become an important part of the guideline evaluation tools.

Objective:To study the antibacterial activity of sanguisorba tannin extract in vitro and its mechanism in the antibacterial effect on staphylococcus aureus. Methods:The antibacterial effect of sanguisorba tannin extract was studied by an Oxford-cup method and a tube double dilution method. With staphylococcus aureus as the tested bacteria, extracellular alkaline phosphatase (AKP), potassium ion, soluble protein and T-ATPase were determined. The changes in protein bands and the cell ultrastructure were respectively observed by SDS-PAGE and TEM to illustrate the antibacterial mechanism. Results:The results showed that sanguisorba tannin extract was effec-tive against the gram-positive bacteria, while the effect against the gram-negative bacteria was weak. After staphylococcus aureus was trea-ted with sanguisorba tannin extract, the contents of alkaline phosphatase (AKP), potassium ion, soluble protein, DNA, RNA and the other large molecules were increased obviously when compared with those in the control group. The concentrations of intracellular and ex-tracellular ATP were significant changed. DS-PAGE showed that staphylococcus aureus treated with sanguisorba tannin extract had no pro-tein band formation. TEM showed that the cell integrity was damaged. Conclusion:Sanguisorba tannin extract shows strong antibacterial activity, which can change the cell membrane permeability and damage the cell integrity.

Objective To retrospectively analyzed the current application of warfarin in hospitalized patients with non-valvular atrial fibrillationand ( NVAF), explore the key role of clinical pharmacists in warfarin medication. Methods A retrospective survey of anticoagulant therapy for 179 hospitalized patients with non-valvular atrial fibrillation in Renming Hospotal of Wuhan University from January to December 2013 was retrived,including the usage of warfarin for NVAF and new-onset atrial fibrillation,dosage,international normalized ratio(INR),hemorrhage event and so on.The simple factor like the age,complicated chronic diseases and previous cerebrovascular events on the use of warfarin was explored. Results The total response rate to anticoagulants was 85.6% for patients with high risk of stroke(27.3% with warfarin and 58.3% with antiplatelet therapy),who are recommended to use warfarin,patient were treated with anti-thrombotic therapy.The total of 19.1% of the patients with new-onset atrial fibrillation used warfarin as therapy.The whole monitoring rate of INR was 89.8%,and the good control rate was 11.9%. Univariate analysis showed that some high risk factors such as age and high blood pressure affected the usage of warfarin. Conclusion The anti-thrombotic therapy for NVAF patients in the hospital is good,but usage of warfarin for those with new-onset atrial fibrillation is low,which couldn't reach the INR standard. More attention should be taken by the clinic pharmacists in effective managing the use of anticoagulant to build a safe,economic and effective medication system for warfarin application.

Objective To investigate the protective effects and mechanisms of granulocyte-colony-stimulating factor (G-CSF)on a rabbit model of chronic myocardial ischemia.Methods Myocardial ischemia models were created by partial ligation of the left anterior descending coronary artery in Japanese white male rabbits.Rabbits were subcutaneously injected with G-CSF (G-CSF group)or saline (control group)for 6 days after myocardial ischemia.The percentage of CD34-positive cells in the peripheral blood was evaluated by flow cytometry,and CD34-positive cells homing and vWF expression in the ischemic myocardium were determined by immunohistochemistry.Results Rabbits in G-CSF group had a higher survival rate than those in control group (P <0.05).Immunohistochemistry of the ischemic myocardium showed that compared with control group,G-CSF group had increased homing of CD34-positive cells on day 7 post-surgery,and more vessels on day 28 post-surgery by anti-von Willebrand factor staining.In addition,we observed an increase in the percentage of CD34-positive cells in the peripheral blood in G-CSF group.Conclusion G-CSF produces an obvious protective effect against chronic myocardial ischemia in rabbits by increasing stem cell mobilization,homing to ischemic myocardium and accelerating neovascularization.

Objective_To evaluate the proangiogenesis of extracelluar matrix proteins SRPX2 on HUVECs.Meth-ods_pcDNA3.1-SRPX2 vector ( transfection group) and pcDNA3.1 vector ( negative group) were transfected into HEK293T cells, then divided into 3 groups including blank group.The proliferation of HUVECs ( absorbance, A450 ) was detected by CCK-8 kit.The transmembrane cell number was counted by Transwell migration and wound healing assay to evaluate the migration ability of HUVECs.A three dimensional culture system of cells was construc-ted on the Matrigel, and tube formation number of HUVECs was assessed.Results_The proliferation of HUVECs ( absorbance,A450 ) among transfection group,negative group and blank group failed to show significant difference (P>0.05).A signifiant difference was noted in the total branch point of capillary tubes among transfection group, negative group and blank group[(97 ±4)/field versus (57 ±3) and (54 ±3)/field] (P<0.05).In wound healing
assay, the distance of transfection group compared to 0, 6 and 12 h were both significantly larger than that of nega-tive group and blank group [(90 ±6), (37 ±7),(36 ±4)μm and (135 ±5),(65 ±8),(63 ±4)μm respective-ly, both( P<0.05) ] .In Tranwell assay, the number of migrating cells in the transfection group was significantly more than negative group and blank group [(549 ±10)/field vs (334 ±11) and (329 ±12)/field(P<0.05)] af-ter co-culture 16 h.Conclusions_SRPX2 may promote angiogenesis by stimulating the migration and tubing on the Matrigel of HUVECs.
