1.Minimally invasive technique for potential application in colorectal cancer surgery
Chinese Journal of Clinical Oncology 2016;43(11):464-466
New technologies and ideas are constantly emerging recently. With the arrival of the era of minimally invasive surgery, most of the colorectal cancer surgeries can be conducted through minimally invasive techniques. In this study, we discuss the status, characteristics, controversy, and consensus of minimally invasive techniques in colorectal cancer surgery.
2.Intravascular Ultrasound-based Computational Fluid Dynamics Simulation of Arterial Vessel Wall Strain Distribution.
Journal of Biomedical Engineering 2015;32(6):1244-1248
Quantitative measurement of strain distribution of arterial vessel walls due to pulsatile blood flow within the vascular lumen is valuable for evaluating the elasticity of arterial wall and predicting the evolution of plaques. The present paper shows that the three-dimensional (3D) strain distribution are estimated through uni-directional coupling for 3D vessel and blood models reconstructed from intravascular ultrasound (IVUS) images with the computational. fluid dynamics (CFD) numerical simulation technique. The morphology of vessel wall and plaques as well as strain distribution can be visually displayed with pseudo-color coding.

3.Expression and significance of uPAR and VEGF-C in hepatocellular carcinoma
Cancer Research and Clinic 2009;21(1):32-34
Objective To investigate the expression of uPAR and VEGF-C in hepatocellular carcinoma (HCC) and its effect on the biological behavior of HCC. Methods The expression of uPAR and VEGF-C in liver tissue specimen of 33 patients with HCC was detected by immunohistochemical staining. Results The positive expression of uPAR and VEGF-C in HCC tissues was located in cytoplasma of cancer cells. The positive rates of uPAR and VEGF-C were 69.7 %(23/33) and 78.8 %(26/33) respectively in 33 cases of HCC. The expression rates of uPAR and VEGF-C were significantly higher in HCC with metastasis than in HCC without metastasis(P<0.05). But there were not significant correlation between the expression of uPAR or VEGF-C and tumor size, tumor grade, AFP level, hepatic cirrhosis. There was a close correlation between uPAR and VEGF-C in HCC(r=0.676, P<0.01). Conclusion The expression of uPAR and VEGF-C is correlated with metastasis, uPAR and VEGF-C may be signs of aggressive phenotype for evaluating treatment and prognosis of HCC. Examination of these two proteins may be helpful to .judge biological behavior of HCC.
4.Expression and clinical significance of matrix metalloproteinase-3 and osteopontin in cervical carcinoma
Cancer Research and Clinic 2010;22(z1):29-31
Objective To study the expressions of matrix metalloproteinase-3 (MMP-3) and osteopontin (OPN) in cervical carcinoma and their relationship with invasion and metastasis. Methods The expression of MMP-3 and OPN were detected in 54 cases of cervical cancer tissues by immunohistochemical SP method. Compared with 15 cases of normal cervical tissues, the relationship was analyzed between both protein expressions and clinical pathology. Results The expression positive rates of MMP-3 and OPN in cervical cancer tissues (70.37 % and 66.7 %, respectively) were significantly higher than those of normal cervical tissues (20 % and 0, respectively), were significantly higher with infiltration depth >1/2 and lymph node metastasis than those with depth≤1/2 and without metastasis , respectively(P <0.05). The expressions of MMP-3 and OPN were related with depth of cervical infiltration and lymph node metastasis of cervical cancer.Expressions between MMP-3 and OPN were significantly positively correlation(r =0.401, P<0.05). Conclusion The expressions of MMP-3 and OPN are correlated with invasion and metastasis of cervical carcinoma.
6.Effect of clopidogrel in patients with non ST segment elevation myocardial infarction during emergency percutaneous coronary intervention
Chinese Journal of cardiovascular Rehabilitation Medicine 2015;24(2):185-188
Objective:To explore the application value of clopidogrel in patients with non ST segment elevation myo‐cardial infarction (NSTEMI) during emergency percutaneous coronary intervention (PCI) .Methods :A total of 168 NSTEMI patients treated in our hospital from Jan 2012 to Feb 2013 were randomly divided into clopidogrel group (n=84) and ticlopidine group (n=84) ,both groups received PCI .Therapeutic effect were observed and compared be‐tween two groups .Results:Compared with ticlopidine group , there were significant rise in percentage of TIMI blood flow grade 3 (88.1% vs .91.7% ) ,white blood cell counting [ (4.0 ± 2.9) 109/L vs .(7.2 ± 2.3) 109/L] and platelet counting [ (101 ± 35) 109/L vs .(141 ± 39) 109/L] ,and significant reduction in percentage of mild bleeding (40.5% vs .19.0% ) in clopidogrel group after operation 28d , P< 0.05 or < 0.01 ;compared with ticlopidine group , there were significant reductions in incidence rates of cardiovascular events (60.7% vs . 27.4% ) and adverse reactions (14.3% vs .10.8% ) in clopidogrel group after six‐month follow‐up ( P<0.05 both) .Conclusion:Clopi‐dogrel possesses satisfying therapeutic effect and high safety in patients with non ST segment elevation myocardial in ‐ farction during emergency percutaneous coronary intervention ,which is worth extension .
