Background and purpose: Fumagillin is an inhibitor of type 2 methionine aminopeptidase that can block blood vessel formation. However, its molecular mechanism and therapeutic value in colon cancer still remain to be elucidated.ln this study, the effect of Fumagillin on the growth of colon cancer was examined. Methods: Twenty mice were divided into 4 groups and injected subcutaneously with 5×10~5/L WiDr or HT-29 cells in 200 μL phosphate-buffered saline (PBS) respectively. After 4 weeks, intraperitoneal injections of Fumagillin (0.1 mg/kg), Cyclo (1 mg/kg), or both were given every 2 days for 4 weeks. The tumor weight and microvessel density (MVD) were examined. Gene-expression profiles were examined by microarray analysis of human umbilical endothelial cells (HUVECs). Results: The Fumagillin-treated mice showed smaller tumor mass and lower MVD-CD105 levels than control ones. In vitro proliferation and tube formation of HUVEC was also significantly decreased by Fumagillin. Microarray analysis of Fumagillin-treated HUVECs showed up-regulation of 71 genes and down-regulation of 143 genes. Expression changes were involved in cell proliferation, migration, adhesion and gene transcription. Quantitative real time-polymerase chain reaction and Westem blot revealed decreased expression of cyclin E2, activated leukocyte cell adhesion molecule (ALCAM), and intercellular adhesion molecule-1 (ICAM-1) genes in the presence of Fumagillin. Conclusion: Fumagillin was found to suppress colorectal cancer growth by suppressing angiogenesis. The down-regulation of cyclin E2, ALCAM and ICAM-1 by fumagillin may be involved in the anti-angiogenesis.

Objective To study the expression of hepatocyte growth factor (HGF) in placenta from normal pregnancy and pregnancy induced hypertension (PIH) and the effect of HGF on angiogenesis in placenta. Methods Immunohistochemistry was used to determine the location and intensity of HGF staining in placenta from 20 cases of normal pregnancy and 58 cases of mild,moderate and severe PIH groups. HE staining was used in order to count the number of the vessles. Results HGF mostly were expressed in villous core mesenchymal cells,less in decidual cells . Intensity of HGF immnostaining in villous mesenchymal cells was significantly reduced in the severe PIH group compared with the normal group(H=7.395,P=0.003),while there were no statistical differences between the mild,moderate PIH group and the normal group (H=0.869,P=0.351,H=0.017,P=0.896) .The count of vessels reduced in severe PIH (F=10.676,P=0.008). There was positive correlation between the expression of HGF and the count of vessels in villous(r=0.246,P=0 030). Conclusion These results suggested that HGF is secreted mainly by villous core mesenchymal cells in human placenta and the reduction of HGF in PIH may be responsible for the impaired vascularization in PIH.

Objective To investigate the incidence and clinical characteristics and look for assay or examination indexes or indicators with higher sensitivity and specificity of heart damage induced by exhaustive exercise in order to establish its preliminary clinical classification and diagnostic criteria. Methods In a military region for training staff,the clinical data of 88 soldiers who were admitted to the departments of cardiology in 6 general or central hospitals because of exhaustive exercise from January 2000 to December 2010 were analyzed. The myocardial enzyme, electrocardiogram(ECG),echocardiography and other related examination indexes or indicators were observed,and the changes of symptoms,signs and other relevant assay and examination indexes before and after treatment were recorded. Results Exhaustive exercise could cause the symptoms such as chest tightness,palpitations,chest pain, dizziness,shortness of breath,fatigue,syncope and other symptoms,as well as cardiac auscultation abnormalities. After treatment, aspartate aminotransferase〔AST(U/L):20.34±6.33 vs. 35.43±25.25〕,α-hydroxybutyrate dehydrogenase〔α-HBDH(U/L):130.47±9.04 vs. 168.93±62.69〕,lactate dehydrogenase〔LDH(μmol?s-1?L-1):2.48±0.62 vs. 3.58±1.34〕,creatine kinase〔CK(U/L):125.58±67.56 vs. 556.42±381.89〕,creatine kinase isoenzyme〔CK-MB(U/L):11.20±4.08 vs. 23.09±15.61〕were significantly lower than those before treatment(P<0.05 or P<0.01);cardiac troponin T(cTnT)was detected in 5 patients,its level after treatment was significantly lower than that before treatment(μg/L:0.07±0.05 vs. 1.26±0.78,P<0.05). The ECG abnormalities included primarily sinus bradycardia (16 cases),sinus arrhythmia (13 cases) and premature ventricular contractions (11 cases). Echocardiographic abnormalities appeared in 18 cases,they were chiefly as follows:valvular regurgitation, cardiac dysfunction,cardiac enlargement,etc,among which the most common one was valvular regurgitation(all the refluxes were of small amount). Based on the above clinical manifestations and examination results,the exhaustive cardiac injuries were preliminarily divided into common type(20 cases),arrhythmia type(56 cases),heart failure type(2 cases)and sudden death(10 cases). Conclusions The clinical manifestations of exhaustive heart damage may appear in different types. Abnormal changes of myocardial enzymes,ECG and echocardiography are the strong evidences for the damage. Clinicians should pay attention to its prevention and treatment.
