Objective: To explore the relationship between the expressions of chemokine receptor CXCR4 and vascular endothelial growth factor C (VEGF-C ) with lymph node metastasis in human rectal cancer. Methods: Immuohistochemical staining was used to detect the expressions of CXCR4 and VEGF-C in 73 samples of human rectal cancer. The relationship between CXCR4 and VEGF-C in 73 samples of human rectal cancer. The relationship between CXCR4 and VEGF-C expressions was analyzed. Results: The positive rate of CXCR4 expression with lymph node metastasis was higher than that without lymph node metastasis (60.1% vs 23.3%,P

Objective: To explore the clinical features and prognosis of breast cancers with different stages in young women. Methods: A retrospective study was made in 61 cases of young patients with breast cancer (≤35 years as young group) and 74 cases of breast cancer patients of control group (36-69 years), who were with stageⅠto Ⅲ disease underwent surgical treatment. Results: The significant differences were observed in pTNM staging and differentiation between two groups. There were no differences between the two groups in stage Ⅰand Ⅱ patients. Significant differences were found between the two groups in stage Ⅲ patients. Conclusion: Breast cancer was with strong invasion in young patients. Early diagnosis and treatment of young women with breast cancer were important to improve the survival rate.

Objective:To analyze and compare the effect of integration of Traditional and Western Medicine treatment and western treatment for patients with severe acute pancreatitis.Methods:According to the including criteria,nineteen randomized controlled trials of this topic were enrolled into the analysis.The detail about the trial design characters of the subjects, results of the studies were reviewed and analyzed by Revman 4.1 software.Results:Compared with integration of Traditional and Western Medicine treatment,western treatment was associated with a significantly higher incidence of mortality(RR=0.35,95%CI 0.25～0.48,P

Objective:To investigate the relationship between high mobility group box-1 protein (HMGB1) expression and gut mucosal barrier dysfunction during murine severe acute pancreatitis (SAP). Methods:Forty-eight male health adult Wistar rats were divided randomly into Control group and SAP groups. The concentration of plasma D-lactate and the activity of myeloperoxidase (MPO) in the intestinal tissue were determined. The expression of HMGB1 mRNA in intestinal mucosa was detected by reverse transcription polymerase chain reaction (RT-PCR) and the activity of HMGB1 was determined by Western blot. Results:Plasma D-lactate and MPO reached a peak level at 24h (16.41?4.65)?g/mL for Plasma D-lactate and(26.76?3.63)U/g for MPO respectively, (P

Objective:To study the expression of EG-1 in thyroid cancer tissue and analyze its correlation with clinical prognosis. Methods:EG-1 mRNA levels in malignant thyroid tissues were evaluated by RT-PCR. All patients were followed up. The survival rates were analyze in EG-1 positive group and EG-1 negative group. Benign thyroid tissues were used as control. Results:EG-1 was expressed in thyroid cancer. The differences between expression of malignant thyroid tissues and benign thyroid tissues were statistically significant (P

Objective:To study the clinical application and postoperative complication of double stapling technique (DST) in anus-preserving operation of low and middle rectal cancer. Method:From April 2002 to April 2006, clinical data of 75 cases with low and middle rectal cancer were analyzed retrospectively. Of those 32 cases used DST underwent sphincter-reserving operation(SPO),regard as study group;and 43 cases used SST received SPO, as control group. Clinical pathologic parameters、 postoperative complication and tumor recurrence were compared between the two groups. Results:Operation of all the 75 patients was successful without operative mortality. In DST group patients, defecation function was different from SST group after postoperative 3 and 6 months (P

Objective:To study the expression and significance of HGF, MMP-2 and MMP-9 in pancreatic carcinoma. Methods:The expression of HGF, MMP-2 and MMP-9 were examined by immunohistochemical technique in 50 cases of pancreatic carcinomas and 10 cases of normal tissues. The relationship between the expression and tumor behaviors were also analyzed. Results:The expressions of HGF, MMP-2 and MMP-9 in pancreatic carcinoma and normal tissues had distinct differences (P

25 ?g/L) before transplantation were followed-up following liver transplantation. Patients were divided into three groups according to the postoperative time of serum AFP below 25 ?g/L, group A (within 1 month ),group B (within 2 months ) and group C(no decreasing or rising after decreasing). Results:The average half-life time of serum AFP of recurrence group was obvious longer than that of the non-recurrence group (P

Objective:To investigate the imaging manifestations and diagnosis of hepatic hereditary hemorrhagic telangiectasia (HHHT). Methods:The imaging features and clinical data of three HHHT patients were analysed and the related data were reviewed. B-type ultra-sonography, contrast enhanced CT and DSA were utilized to show the changes of the involved liver and the vessels. Results:B-type ultra-sonic graph showed abnormal blood vessels in hepatic hila. CT or DSA demonstrated intra-and extra-hepatic abnormal ectatic arteries, intrahepatic telangiectasia, cirrhosis and hepatic enlargement. Conclusion:CT might be used as one of the key measures for the diagnosis of HHHT.

Objective:To explore the value of different MRI sequences in the diagnosis of breast lesions. Methods:Using Philips Achieva 1.5T Nova Dual MRI with SENSE～ breast coil, MRI scanning was performed on 21 patients clinically suspected suffering from breast cancer. MRI sequences included T1WI/TSE,T2WI/TSE (turbo spin echo), short TI inversion recovery(STIR),diffusion weighted whole body imaging with background body signal suppression (DWIBS) and dynamic contrast-enhanced MRI scanning THRIVE. MRI findings were compared with histopathological results. Results:The detection rates of breast lesions of the five sequences were 53.85%, 65.38%, 80.77%, 88.46% and 100%. The sensitivity, specificity and accuracy of dynamic contrast-enhanced MRI scanning were 100%, 77.78%, and 92.31% respectively, which were better than other sequences in the differential diagnosis of the lesions. Conclusion:Dynamic contrast-enhanced MRI scanning could accurately show the numbers of the lesions, describe the morph and size of the lesions and provide more information for the surgeons. DWIBS and STIR could detect the breast lesions more sensitively than T1WI/TSE and T2WI/TSE sequences.
