Objective To explore the expression of 10 kDa interferon-gamma-induced protein(IP-10)in pathological scar and its role in the pathogenesis of pathological scar.Methods Imrnunohistochemistry was performed to detect the expression and distribution of IP-10 in 28 patients with keloid(group K),34 patients with hypertrophic scar(group HS),and 20 normal controls(group N).The data were collected and analyzed statistically.Results The expression of IP-10 was significantly higher in groups K and HS than in group N(P<0.01),but no significant difference in the expression of IP-10 was found between groups K and HS.Conclusion IP-10 may enhance the formation of pathological scar by attracting T lymphocytes and inducing immune/inflammatory response.

Oncology is extensive in contents,covering a wide range of organs,systems and clinical specialties.Here,we discuss the feasibility and necessity of flipping the classroom teaching through the introduction of Oncology and through the implementation of flip classroom teaching for oncology graduate students,this paper analyzes the evaluation of the classroom teaching by the teachers and students,and compares the assessment results of students under different teaching methods.The results show that the flipped class can promote students' initiative learning,promote students' classroom participation,and help students to internalize and consolidate their knowledge of oncology in the theoretical teaching of graduate oncology.

Objective To analyze CT manifestations of inguinal canal lipomas (ICLS).Methods CT datas of 104 pa tients with ICLS was retrospectively analyzed.And the imaging features were observed by MPR.Results The main CT manifestations of the ICLS were fat density in the inguinal canal and were unconnected with the abdominal fat.Among the 104 ICLSpatients,male (90/104,86.54%) was more than famale(14/104,13.46%;x2=55.538,P<0.001).Thele sions were located at bilateral sides in 8 cases,left side in 66 cases and right side in 30 cases.The lesions in left side were more than those in right side (x2 13.500,P<0.001).The mean maximum cross-sectional area of ICLS was (3.89 ± 2.12)cm2.There was no statistically significant difference between male and famale in maximum cross-sectional area (t=1.038,P=0.302).Conclusion In ICLS patients,male is more than famale.And more lesions are located at the left side.The CT manifestations of ICLS have certain characteristics,and MPR images are helpful in diagnosing ICLS.

Objective To study the surgical treatment of major blood vessels invaded by tumors in order to raise the resection rate and postoperative survival rate. Methods Clinical data were analyzed on 26 patients undergoing (resection) of tumors along with reconstruction of major blood vessels from October 1998 to February 2004. Results Tweety-three cases were followed up for 2~65 months with median 42.8 months. Doppler ultrosonography and CTA examination were performed respectively during the follow-up process.In 5 patients with carcinoma of the head of pancreas who had inferior vein cava replaced and in 1 patient with cholangiocarcinoma who had portal vein replaced,3 were complicated with carcinoma embolism formation at 3,12 and 15 months respectively after surgery,(postoperative) graft patency was 50%;all of the 6 patients had recurrence of the tumor at 3,6,8,12,24 and 31 months respectively after surgery.Seven patients with tumor in pelvic cavity or in posterior space of peritoneum were followed up for about 2 years,1 of them had tumor recurrence ,but the graft kept patent,2 patients with sarcoma in the limbs were followed up for 1 year without tumor recurrence or vessel obstruction.Eleven patients with tumors in the neck were followed up for 3 months to 5 years without tumor recurrence or vessel obstruction. Conclusions (Combination) of resection of neoplasm and reconstruction of major blood vessels is safe,effective and practical method for patients with major wessels invaded by tumor.

AIM: To analyze the effect of human amniotic homogenate extract on corneal neovascularization after corneal alkali burn in the process of pigment epithelium derived factor (PEDF) and vascular endothelial growth factor (VEGF) expression and the effect of corneal neovascularization.METHODS: Totally 32 patients with corneal alkali burn were selected from June 2015 to June 2016 in Foshan,and were randomly divided into Group A and Group B,with a total of 37 eyes.Group A of 17 cases,with a total of 19 eyes,were treated with 40mg/L human amniotic homogenate extract;Group B (n=15),and 18 eyes,treated with 3g/L prednisolone eye drops.In the treatment of 1,4,7,14,21 and 28d at different time points,we observed the growth of corneal neovascularization,and detected the expression of PEDF and VEGF during angiogenesis.RESULTS: Group A of patients in the use of human amniotic homogenate extract after the treatment,the expression level of PEDF was significantly higher than that in Group B(P=0.001),after 28d treatment,the expression level of PEDF reached 0.721±0.314.While patients in Group B the expression level of PEDF was only 0.538±0.253.Two groups had significant difference between the expression level of PEDF (P<0.05).The expression level of VEGF in Group A was lower than in Group B at different time points in the test.After the treatment of 28d patients in the Group A,the expression level of VEGF was 0.152±0.020,in Group B the expression level of VEGF was0.302±0.031.Two groups of patients with VEGF expression level between the differences were statistically significant (P<0.05).The patients number in Group A with corneal neovascularization was significantly lower than that in Group B,the difference was statistically significant (P<0.05).CONCLUSION: Human amniotic homogenate extract can increase the expression of PEDF in corneal neovascularization after corneal alkali burn,inhibit the expression of VEGF and the proliferation of corneal neovascularization.
