Objective To compare the diagnostic value of CT and diffusion-weighted imaging in extremity soft tissue tumors. Methods A total of 104 cases of extremity soft tissue tumors were examined with CT scanning and MRI. All cases were histologically proven. Then we compared the CT value of various types of tumors. The b values of diffusion were 0 and 500 s/mm2. The apparent diffusion coefficient (ADC) values of a large region with no hemorrhage, necrosis, scar tissue, or calcification representing the lesion were measured. ADC values of benign tumors, malignant tumors and normal muscles were compared. Results There were 68 cases of benign tumors and 36 cases of malignant tumors. The CT findings of 45 cases and the MRI findings of 87cases were in accordance with pathological examination. The diagnosis of 59 cases by CT and 17 cases by MRI were wrong. The CT features of soft tissue tumors showed the low density masses. The features of lipoma or cyst were typical on CT. There were large differences among the different types of tumors performance on T1WI and T2WI. The ADC values of the malignant tumors were significantly lower than those of benign lesion sand muscles (P < 0.01). There was no significant difference in ADC values between benign lesions and muscles. there was significant difference between the detection level of CT and MRI (P < 0.01). Conclusion CT can clearly show soft tissue tumor lesions and to clarify their relationship and the surrounding tissue, but can not accurately characterize. MRI diffusion-weighted imaging can better differentiate benign and malignant, and speculate the histological lesions sources. MRI detection level is significantly higher than CT and more consistent with a higher degree of pathology. Thus in the preoperative diagnosis of soft tissue tumors, diffusion-weighted imaging MRI should be preferred.

Background and purpose:Matrix metalloproteinase11(MMP-11)is an interesting member of the MMP family,and its overexpression has been demonstrated in human cancers such as non-small cell lung cancer and oesophageal adenocarcinoma.Furthermore,strong MMP11 gene expression is correlated with both increased aggressiveness of tumors and a poor clinical outcome,but there was no related reports on gastric cancer.We focussed our study on the significance of MMP-11 expression in gastric cancer.Methods:MMP-11 was selected and confirmed at both mRNA and protein level in 130 cases of gastric cancer serum specimen by RT-PCR,enzyme-linked-immuno-sorbent-assay(ELISA)techniques,respectively.Results:The total positive rates of serum MMP-11 mRNA in gastric cancer and healthy people were 68.4% and 5%,respectively.Our data demonstrated that MMP-11 protein levels in gastric cancer were(44?27)ng/ml,significantly higher than those in control subjects(P=0.001).MMP-11 protein levels in 30 cases with recurrence were(51?27)ng/ml and(27?28)ng/ml in 30 patients without recurrence.MMP-11mRNA positive expression was consistent with MMP-11 protein levels in gastric cancer patients.Conclusions:Serum MMP-11 may play an important role as a biomarker in diagnosis and prediction of recurrent gastric cancer.

Objective To explore the efficacy and safety of modified vaginal paravaginal repair (VPVR) in treatment of symptomatic paravaginal defect cystocele(PDCC). Methods This study was an observational case series of 52 consecutive women in Beijing hospital from January 2007 to August 2009, with symptomatic paravaginal defect cystocele. Among them, 6 patients had anterior wall colporrhaphy. Preoperative and postoperative pelvic evaluations were performed with the POP-Q system. All the cases underwent vaginal approach to paravaginal repair, 49 cases underwent vaginal hysterectomy simultaneously. Patients were followed up for 1 to 24 months. Criteria for objective cure were defined as the anterior vaginal walls at grade 0 and firmly apposing to the lateral pelvic sidewalls.Results Of the 52 patients, 30 had grade Ⅱ , 17 had grade Ⅲ, and 5 had grade Ⅳ paravaginal defect cystocele. In all patients the VPVR was performed successfully. No complication happened during and after operation. The average operation time was (65 ±18) min (45-110 min) and estimated blood loss was (95 ± 27) ml (50-200 ml). Patients were followed up postoperatively for 3 to 24months, with a mean of (10. 1±3.1) months. The PDCC recurred in 6 cases, 5 patients had grade Ⅰcystocele and 1 had grade Ⅲ cystocele. Conclusions The vaginal approach to the correction of paravaginal defect cystocele is highly effective in our population.
