Objective To study the effect of Src tyrosine kinase inhibition on subcutaneously transplanted tumor of human lung adenocarcinoma in mice and its mechanism. Methods For the subcutaneously transplanted tumor model, A549 cells or PC-9 cells were inoculated into SCID mice by subcutaneous injection. Immunohistochemistry was used to show the effect of Src tyrosine kinase inhibition on proliferation index (Ki-67 staining) and microvessel density (CD31 staining) of subcutaneously transplanted tumor of human lung adenocarcinoma in mice. Results Subcutaneously transplanted tumor of PC-9 cells was sensitive to src tyrosine kinase inhibitor. There was significant difference between treatment group and control group (P <0.01). There was significant difference between the two treatment group too (P <0.01). Stopping treatment for 1 week, the inhibition rate of tumor growth were 33.19 % and 84.79 % in 10 mg·kg-1·d-1 and 50 mg·kg-1·d-1 treatment group, respectively. The same treatment was less effective to subcutaneous tumors produced by A549 cells. Treatment with 50 mg·kg-1·d-1 Src tyrosine kinase inhibitor significantly reduced the proliferation index of subcutaneously transplanted tumor produced by PC-9 cells (P<0.01) and tended to reduce the proliferation index of subcutaneously transplanted tumor produced by A549 cells (P >0.05). Treatment with 50 mg·kg-1·d-1 Src tyrosine kinase inhibitor significantly reduced micro vascular density in both PC-9 and A549 induced subcutaneous tumors (P <0.05). Conclusion Inhibition of Src tyrosine kinase could suppress the progression of subcutaneously transplanted tumor, not only by the inhibition of cell proliferation of lung adenocarcinoma cells directly, but also by the inhibition of angiogenesis indirectly.

Objective: To improve the understanding of the clinical feature and early diagnosis of relapsing polychondritis(RP). Method: Eleven patients with RP were analyzed retrospectively and the reported literatures were reviewed. Result: Nine cases had initial involvement of auricular cartilage while two polyarthritis. The treatment of 2RP patients with respiralory tract involvement was invalid and 1 patient died. Nine cases were initially misdiagnosed, with a misdiagnosis rate of 81.82%. Conclusion: RP involves cartilage and connective tissue. The prognosis with respiralory tract involvement is poor. RP is a sort of paroxysmal and progressive inflammation involving cartilages all over the body with a variety of clinical manifestations. Early diagnosis of RP is based on full understanding of its clinical features.

Objective To study the interventional effects of Candesartan Cilexetil on vascular endothelial function and expres-sions of ERK/CREB signaling pathway in rats with acute myocardial infarction.Methods 30 rats were randomized into CAN group,AMI group and Sham group.Two weeks after the treatment rats were sacrificed and blood pressure,levels of blood AngⅡ, NO and NOS,endothelial vasomotor effects of isolated thoracic aorta strips,myocardial infarctual area and the expressions of ERK mRNA and CREB mRNA in infarctual myocardium were explored.Results Blood AngⅡ levels were distinctly higher in AMI group when compared with the Sham group,while the NO and NOS level were much lower.accompanied with EDDs decreased seri-ously,and higher mRNA expressions of ERK1 and CREB in infarctual myocardium.All of the above differences were significant. After the treatment of Candesartan Cilexetil,levels of serum NO and activities of NOS were obviously higher and almost reached the similar levels to those in Sham group,additionally endothelium-dependent diastole in isolated aortic strips improved greatly.Mean-while Candesartan Cilexetil can not only increase the plasma AngⅡ,but also decrease the size of myocardial infarction and the mR-NA expressions of ERK1 and CREB in infarctual myocardium significantly.However,blood pressure in all groups was not affected. Conclusion Candesartan Cilexetil can greatly improve the disordered endothelial function developing post-AMI,decrease the size of myocardial infarction and down-regulate the mRNA expressions of ERK and CREB in myocardium of infarctual zone.And all of the above protective effects of Candesartan Cilexetil were independent on blood pressure lowering.

Objective To investigate the injury characteristics and prognostic risk factors of patients with craniocerebral injury so as to provide some suggestions for the improvement of medical prevention,intervention and treatment measures.Methods Trauma database system was applied to collect the medical records of 661 patients with traumatic brain injury admitted to the Department of Neurosurgery of 105th Hospital of Hefei in 2009.Their general conditions,injury characteristics and outcomes were analyzed and the risk factors affecting their outcomes were investigated by Logistic regression analysis.Results Of the patients with craniocerebral injury,the males accounted for 70％ (463/661).The patients at 45 years old or so had the highest incidence of craniocerebral injury.Patient number in the second half of one year was 1.65 times more than that in the first half of one year (412/249 ).Most patients were injured from traffic accidents (87.7％,580/661 ) and 512 patients (77.5％) suffered from multiple injuries.ISS,injury causes,age and injury incidence quarters showed close correlation with the final outcome.Conclusions The patients with craniocerebral injury demonstrates distinctive characteristics in aspects of gender,age,incidence time,injury causes,and multiple injuries,but the ultimate outcomes are related to the injury severity,injury causes,age and other factors.
