Objective To study the content of urokinase-type plasminogen activator receptor(uPAR)in the peripheral blood to investigate its value for the invasion metastasis and prognosis in cervical cancer.Methods The plasma level of suPAR in 30 normal women.94 patients with cervieal cancer was measured by using enzyme linked immunosorbent assay(ELISA).Results The mean level of suPAR was(0.5023±0.1724)ng/ml in plasma of 30 normal women,while that in plasma of 94 cervical cancer patients was (1.0433±0.2736)ng/ml.The plasma suPAR level of cervical cancer patients was increased in comparision with that of normal women (P＜0.01).The suPAR level in the cervieal cancer patients did not show a significant correlation with histological classification,histological grade,style of growth and tumor size(P＞0.05),but was related to clinical stage.lymphnode metastasis and depth of invasion (P＜0.05).Conclusion Plasma suPAR would be a more reliable and convenient indicator in monitoring uPA system,and could be widely used as a new tumor marker in clinic.

Objective To evaluate the significance of suPAR,SCC-Ag in plasma and HPV16,18 in cervical secretion for monitoring pathogenetic condition and prognosis in patients with cervical cancer.Methods 206 cervical cancer patients blood and cervical secretion were collected.Plasma level of suPAR and SCC-Ag were measured by enzyme linked immunosorbent assay (ELISA) in health women and patients with cervical cancer.The expression of HPV16,18 of cervical secretion in control group and patients with cervical cancer were detected by fluorescence quantitative PCR.The correlations of the three indexes were analyzed.Results The plasma level of suPAR and SCC-Ag,the expression of HPV16,18 of cervical secretion in cervical cancer patients were obviously higher than those in health controls with statistical significance ((1.072 5±0.305 2) ng/ml vs (0.501 7±0.179 3) ng/ml,(0.980 6±0.162 7) μg/ml vs (0.261 4± 0.006 3) μg/ml and 53.89 ％ (90/167),46.15 ％ (18/39) vs 6.67 ％ (4/60),P ＜ 0.05).There was a positive correlation between plasma suPAR level and SCC-Ag level in invasive carcinoma of cervix patients (r =0.564,P ＜ 0.05).The plasma level of suPAR between in HPV16,18 positive group and in HPV16,18 negative group did not show difference (P ＞ 0.05).Conclusions In invasive carcinoma of cervix patients,there is a positive correlation between plasma suPAR level and SCC-Ag level.But it's not yet to conclude that plasma suPAR level of cervix invasive carcinoma patients is related to infection of HPV16,18.

Objective To explore the feasibility of local enucleation of pancreatic cystadenoma. Methods From Jan 2001 to Dec 2007, 11 patients with pancreatic cystadenoma underwent operation in Department of General Surgery, first affiliated hospital of China Medical University were enrolled and the clinical features, complications and prognosis were analyzed retrospectively. Results Of the 11 cases, the average age was 47 years old with 2 males and 9 females, the average size of the neoplasm was 4.8cm and 1 located in the pancreatic head, 10 in the body or the tail. Among which 3 cases were serous cystadenoma and 8 were mucinous cystadenoma confirmed by pathological evidence. Three patients developed temporary hyperglycemia and returned to normal after 1~2 weeks; one patient developed incisional infection; two cases developed pancreatic fistula postoperatively. All cases were followed up between 28 and 67 months. No neoplasm re-occurrence or diabetes mellitus occurrence were observed. Conclusions It was safe and feasible to perform enucleation for pancreatic cystadenoma with tumor size less than 6 cm.

Objective To detect and analyze the expression of ER and PR in endometrial benign and malignant tumor,and to study its correlation of ER and PR with the establishment and development of endometrial carcinoma.Methods The expressions of ER and PR were examined by immunohistochemical method in 58 eases of endometrial carcinoma,37 cases of atypism endometrial hyperplasia,25 cases of simple endometrial carcinoma.and 25 eases of normal endometrium.Results The expressions of ER and PR were higher in normal endometrium,atypism endometrial hyperplasia and endometrial carcinoma.They were lower in endometrial carcinoma than in atypism endometrial hyperplasia,both were higher than that in normal endometrium(P＜0.05).The rates of expression in ER and PR increased gradually from histological grade Ⅰ,Ⅱto Ⅲ.The expressions of ER and PR in histological grade Ⅰ were significantly different from that in histologic grade Ⅲ(P＜0.05).There were no correlation between expressions and ages,which expression rates less than 50 years were higher than those above 50 years.Its expression W88 not related to different clinic grade(P＞0.10).Conclusion The expressions of ER and PR increased gradually from normal endometrium,atypism endometrial hyperplasia to endometrial carcinoma.ER and PR expressions were obviously related to histologic degree.It maybe related to establishment and development of endometrial carcinoma.

Objective To explore the relationship uPAR in tissue and plasma of patients with cervical carcinoma and its clinical pathophysiological characteristics. Methods The preoperative plasma cancer tissue and its adjacent tissue in 42 cases of patient with ⅠB～ⅡA cervical carcinoma and the preoperative plasma and postoperative cervical tissue in 30 cases of patient with hysteromyoma were collected. Their uPAR were detected by ELISA. Results uPAR in the plasma of patients with cervical carcinoma was significantly higher than those in healthy controls and in patients with hysteromyoma. It was related to tumor invasive depth and lymph node metastasis and not related to tumor differentiation, uPAR in cancer tissue of patients with cervical carcinoma was significantly higher than those in normal cervical tissue. It was related to tumor differentiation and not to tumor invasive depth and lymph node metastasis. Conclusion uPAR in the plasma of patients with cervical carcinoma is related to invasion and metastasis, uPAR in the tissue is related to tumor differentiation.

Students generally felt difficult in studying during clinical practice and the orthopedics teaching quality was unsatisfactory due to the discrepancies existed among teaching of anatomy,imagie and orthopedics clinical practice concerning the time,content,requirement and method.Students' understandings of anatomy and image knowledge were improved through launching theoretical study by means of lectures and case discussion.Students' understandings of orthopedics diseases were promoted through preoperative diagnosis and intraoperative conformation using anatomy and image knowledge for the patients they were responsible for.In all,orthopedics clinical teaching quality was promoted through applying these measures.

Objective:To collect the imaging data and related materials of the patients with in-stent restenosis (ISR)after coronary artery stent operation with intravascular ultrasound (IVUS),and to analyze the risk factors of ISR,and to propose the reasonable intervention strategies.Methods:Fifty patients with ISR were divided into ISR ≤ 50% drug group (n = 14 )and ISR > 50% drug group (n = 36),including drug-coated balloon therapy group (n=16)and stent treatment group (n=20);IVUS virtual organization technology was used to compare the plaque area,location,tissue composition,thrombus and other factors of the patients in various groups after treatment;the data changes after 6 months of follow-up were analyzed.Results:The IVUS results showed the plaque areas and plaque loads of the ISR patients treated with intervention were significantly reduced compared with before operation (P <0.05);the plaque compression degree of the patients in drug-coated balloon therapy group was lower than that in stent treatment group (P <0.05),but the differences were not found between drug-coated balloon therapy group and stent treatment group in fibrous tissue components and calcified tissue proportion (P >0.05).Conclusion:The ISR rate is higher in the patients with high degree of fiber components,plaque composition heterogeneity and distribution of diffuse tortuous and calcified lesions.ISR has no significant correlation with the plaque wall thickness and lipid content and plaque instability and necrotic tissue proportion.

Objective To evaluate different post-processing imaging techniques of multi-slice helical CT cholangiography (MSCTC). Methods Fourty-seven patients were suspected of bile duct disease by ultrasound, with no abnormality by ordinary CT. These patients then received MSCTC examination. The original images were post-processed at workstation. The result of post-processed images was compared with that of the laparotomy and surgical bile duct endoscopy. Results Procedures were successful in 45 cases. Thirty-one cases were found with choledocholithiasis. The specificity and the sensitivity of CT virtual endoscopy (CTVE) for choledocholithiasis group were high. Cholangitis and cholangiocarcinoma were detected in 3 each cases.Three cases were finally found to have gallbladder polypus, in which only CTVE provided the diagnosis. The diagnosis of bile duct disease made by ultrasound were finally excluded by CTVE. Conclusions KG1 The available post-processing methods are CTVE and X-proj, MPR is applicable for observing bile duct wall, it is valuable in the diagnosis of all kinds of bile duct disease. CTVE is better than other methods at displaying intraluminal structure.
