Objective To study the effects of basic fibroblast growth factor gene in enhancing collateral vessel formation of coronary artery in the ischemic myocardium of swine.Methods All swines were distributed into the operation control group(n=6) and treatment group.The treatment group was further divided into 2 groups according to the route of injection either through the right coronary artery or the left coronary(n=6 respectively).The animal models of AMI were prepared by ligating the left circumflex(LCX) coronary artery.Two weeks after the operation,2?000 ?g of pcDNA_3-bFGF eukaryotic expression plasmid was directly injected into the coronary artery by catheter.Two weeks after the gene injection,evaluation of collateral circulation formation was made by means of coronary angiography and immuohistological staining ect.Results (1) Through immuotistological staining,the vessels count in both treatment groups was more than that in the control group;(2) Selective coronary angiography at 4 weeks after the operation showed that the number of newly formed collateral vessels in the bFGF gene treatment group was more than that in the control group.On the other hand,more collateral vessels were found in the group through left coronary injection compared with the group through right coronary injection.Conclusion Intra-coronary artery injection of bFGF gene can improve collateral vascular formation in the ischemic myocardium of swine.

Objective To discuss the clinical manifestation and pathology of papillary renal cell carcinoma (PRCC).Methods From January 2007 to January 2012,the clinical and pathologic data of 25 patients (17 males and 8 females with average age of 54 years ranging from 24-76 years) with PRCC were retrospectively analyzed in combination with review of literature.The clinical stages of the tumor were as follows,Ⅰ in 16 cases,Ⅱ in 5 cases,Ⅲ in 4 cases.And the radiographic inspections of PRCC were compared with that of 100 randomly selected clear renal cell carcinoma (CRCC).Results All the PRCC cases had different imaging presentations compared with CRCC.CT attenuation of CRCC was higher than that of PRCC in corticomedullary,nephrographic and excretory phase (P＜0.05).Heterogeneous enhancement was most commonly seen in CRCC than PRCC (P＜0.05).There were 21 patients underwent radical nephrectomy,and 4 patients underwent laparoscopic nephron sparing surgery.The pTNM stages of the tumor were as follows,pT1N0M0 in 16 cases,pT2N0M0 in 5 cases,pT3aN0M0 in 2 cases,pT1N1M0 in 1 case,,pT2N1M0 in 1 case.Of these 25 patients,8 (32％) and 17 (68％) were diagnosed as type Ⅰ and type Ⅱ PRCC,respectively.All the 25 cases of patients were followed up from 6 to 60 months.One case died of metastasis,1 case died of cerebrovascular disease and the other 23 patients survived with tumor-free.Conclusions PRCC is a special type of RCC with low morbidity.Radiological examination can be used in the differential diagnosis of CRCC and PRCC before surgery.The prognosis after surgical treatment is good,but the adjuvant systemic treatment is to be study.

Objective an experimental animal model of acute myoc ardial infarction (ANI) was established by opening chest and ligation of the left anterior descending (LAD) coronary artery． Methods a total of 20 rabbits were opened chest and ligated LAD under sterilization． Electrocardiogram (ECG) and myocardial-enzymes in blood serum were investigated． Results ECG of all rabbi t s showed normal before operation． Irmediately after and 1/2 hour after ligation , ST-segment elevated and ECG showed ambulatory changes for 7 and 9 rabbits respectively． Two hours after LAD ligation, the change of ECG for 2 rabbits wa s not typical and 2 of them died during experiment． Four weeks after operation, E CG of 18 rabbits showed the chest leads had pathologic Q waves． Twenty-four ho urs after LAD ligation, AST, LDH, LDH-1, CK and CK-MB in blood serum were significantly increased． There was significant difference compared with before operation (except LDH) (P<0. 0l)． Conclusions:The method was sim ple and well repeated． The formation of myocardial infarction was reliable and rabbits were maintained for a long time after operation． It provides a valuable animal mode l for the experiment study of coronary heart disease．

Objective To study the biomarker panel of superficial bladder transitional cell carcinoma(SBTCC)and analyze the biological pathway in tumorigenesis by Shotgun proteomics strategy.Methods Normal urothelium cells and cancer cells were harvested by laser capture microdissection from clinical specimen and the proteomic expression profile was identified by two-dimensional liquid chromatography tandem mass spectrometry.The isoelectric point,molecular weight,grand average of hydropathicity,transmembrane helices were analyzed by using proteomics tools.Gene ontology was used to comment the identified proteins.The pathway analysis was performed by ArrayTrack software,and visualized by GenMAPP.Results There were 440 and 218 proteins expressed in cancer cells and normal cells respectively,among them 388 proteins were differerntially expressed.All the database about identified proteins was deposited in an accessible form to researchers at http://www.Proteome-SBTCC.org.cn and http://www.Proteome-NHTE.org.cn.There were 267(68.8%)differentially expressed proteins which had GO biological process comments.The biological pathwavs of these proteins included MAPK signaling pathway,focal adhesion,oxidative phosphorylation,ECMreceptor interaction,etc.Conclusion Shotgun strategy proteomies database of normal transitional epithelium and SBTCC is successfully constructed.And the basis for the understanding of cell biology and discovery of biomarker panel for SBTCC iS provided.
