Objective To analyze the correlation between the levels of urinary ptasminogen activator receptor (uPAR) and the clinicopathological characteristics of patients with cervical carcinoma and it's clinical significance. Methods SABC immunohistochemistry was employed to detect the expression of uPAR in 50 cases of cervical carcinoma tissue and 50 cases of normal cervical tissue. ELISA method was used to determine the serum uPAR levels for the patients with cervical carcinoma. Results There was no expressionfor uPAR in normal tissues, The positive expression rate of uPAR was 66 % (33/50). The uPAR level of cervix cancer tissues [(70.92±28.55) ng/100 mg protein]was significantly higher than those in normal tissues [(11.01±5.40) ng/100 mg protein], (P <0.001). and uPAR levels were closely related to clinical stages,lymphatic metastasis and differentiation degree (P <0.05), but not related to deep myometrial invasion and vascular embolization (P >0.05) (however, they were not related to patient's age, tumor growth type and the size of tumor. Significant difference of uPAR level was observed between the patients with cervical carcinoma [(2.38±0.29) ng/ml]and in healthy controls [(0.50±0.16) ng/ml](P <0.001). Single factor analysis indicated that, before the treatment, the serum uPAR levels were closely related to clinical stages, lymphatic metastasis, vascular embolization, and deep myometrial invasion (P <0.05-P <0.01). However, they were not related to differentiation degree (P >0.05). Multifactor regression analysis showed that the pretreatment serum uPAR levels of patients were related to clinical stages (P =0.000), cavum pelvis lymphatic metastasis (P =0.000) and deep myometrial invasion. Patients with cervical carcinoma showed a dramatic drop in serum uPAR levels after treatment, which were significantly different compared to their pretreatment uPAR levels (P <0.001). Linear correlation analysis showed that there was a positive correlation between serum and tissue uPAR levels, (r =0.801, P <0.001). Conclusion There were high expression of uPAR in serum and tissues with cervical carcinoma. Pretreatment serum uPAR levels were closely related to patients' clinical stages,cavum pelvis lymphatic metastasis and deep myometrial invasion, serum uPAR levels may be an important tmnor marker for the diagnosis, detection, prognosis of cervical carcinoma.

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.
