Objective To evaluate the CT manifestation of pancreatic carcinoma proved by patholoical results. Methods The patients were supine. Both plain and three-phase dynamic contrast-enhanced CT scan were performed. 100 ml of Ominipaque was injected at a rate of 2～4ml/s, with 5~10 mm slice thickness and interval. Results CT scanning clearly showed the direct signs or indirect signs of pancreatic carcinomal, which include: pancreatic mass, obstructive dilatation of the bile duct and pancreatic duct, the visualization of the abnormal large peripancreatic vessels, lymph node metastasis, etc. Conclusion Plain CT scanning shows clearly manifestation of pancreatic carcinomal and the surrounding tissue, and three-phase dynamic contrast-enhanced CT scan can clearly display the tiny changes of pancreatic parenchyma. Therefore it is valuable for diagnosis of pancreatic carcinomal.

Objective:To evaluate the efficacy of the resection of nasal inverted papilloma (NIP) under endoscope.Methods: A total of 100 patients with NIP from April 2008 to December 2013 in our hospital were randomly divided into endoscopic surgery group (endoscopic group) and conventional surgery group (conventional group), each with 50 cases. All patients were followed up for 2 years, whose recurrence, complications and satisfaction were observed. Results: The patients were followed up for 2 years, and the recurrence rate between the two groups was not statistically significant (x2=0.96,P>0.05). The traditional group had a higher incidence of complications than the endoscopic group, and the difference was statistically significant (x2=4.16,P<0.05). Endoscopic patients’ satisfaction was higher, and the difference was statistically significant (x2=5.02,P<0.05).Conclusion: The resection of (NIP) under endoscope can reduce the incidence of complication, improve patient satisfaction, and will not increase the recurrence rate, which is an effective means of treatment to the NIP.

Objective To study the risk factors for contralateral breast cancer(CBC) in women after regular treatment of the primary breast cancer.Methods Between January 1997 to December 2002,the clinical data of 340 breast cancer patients at our institution were retrospectively analyzed.In all the patients a detailed analysis was carried out with respect to age,operation type,radiation therapy technique and dose,the use of chemotherapy or hormone therapy,and other clinicopathologic characteristics.The Kaplan-Meier method was used to estimate the actuarial rate of CBC.The Cox proportional hazard regression model was used to estimate the relative risk factors of CBC.Results Fourteen cases were diagnosed to be CBC,thus overall incidence of CBC was 4.1%.Ten-year CBC incidence(2.7%) was higher than 5-year incidence of CBC(1.4%).Univariate analysis showed that the risk factors of CBC at 5-year and 10-year included: ≤45 years old,medullary carcinoma,family history of breast cancer and being taken without endocrine therapy(P0.05).Mutivariate analysis showed that ≤ 45 years old and being internal breast radiotherapy were independent risk factors of CBC at 5-year and 10-year(P

[Objective]To analyze the clinical effect of intertrochanteric fractures treated with percutaneous proximal femoral nails(PFN).[Method]From January 2004 to May 2009,PFN using percutaneous technique was performed in 180 elderly patients of femoral intertrochanteric fractures(180 hips,80 males and 98 females),with mean age of 76 years(range from 57-99 years).According to Evans classification,12 cases were type Ⅰ,28 were type Ⅱ,62 were Ⅲa,20 were Ⅲb,49 were Ⅳ,9 were Ⅴ.Traction table and C-arm fluroscopic intensifier were used with close reduction and interlocking during the course of operation.[Result]One hundred and seventy two cases in 180 patients were followed up for 8 to 21 months with a mean of 13.5 months.Other 8 patients were lost to follow up after discharge.Of 172 patients followed up,166 cases' radiographs showed the callus during 6-8 weeks postoperatively,while they had a full range of hip motion as the original level.Partial weight bearing exercises were carried out since the 8th postoperative week.The time of clinical fracture healing was from 12 to 16 weeks,the rate of healing was 98.8%.In the function assessment of 172 patients the satisfactory rate reached to 87.8 percents.[Conclusion]Percutaneous proximal femoral nails is an ideal way for the treatment of intertrochanteric fractures in aged because of its simple procedure,minimal invasion,less fluoroscopy exposures,less complications,stable fixation,early fracture healing and satisfied functional outcomes.

Objective To investigate the expressions of cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) in colonic mucosa of patients with ulcerative colitis (UC)and to analyze the relationship between them. Methods The specimens of colonic mucosa from 32 UC patients were graded according to endoscopic and histological grading standards, and specimens of colonic mucosa from 26 healthy controls were also collected. The expressions of COX-2 and 5-LOX mRNA and protein in colonic mucosa were determined using real-time fluorescent quantitative reverse transcription polymerase chain reaction(RT-PCR) and immunohistochemistry. The correlation between COX-2 and 5-LOX was analyzed. Results For UC patients,10 were class 1, 19 class 2 and 3 class 3 according to endoscopic grading, whereas 19 were class Ⅰ , 9 class Ⅱ and 4 class Ⅲ according to histological grading. The expressions of COX-2 and 5-LOX mRNA in active UC patients were 81. 25% and 53.13%, respectively, and were 11.54% and 19. 23% in healthy controls, respectively, with significant differences between the two groups (all P values＜0.01). The positive expressions of COX2 and 5-LOX increased in accordance with increasing of endoscopic grading and histological grading.The levels of COX-2 and 5-LOX were 20. 08±1.17 and 37.83 ±1.48 in colonic mucosa tissues of UC patients, respectively, and 48.42 ± 1.69 and 11.28 ± 1.62 in healthy controls, respectively. There was significant difference between the two groups (all P values＜0.05). A good positive correlation was found between COX-2 and 5-LOX. Conclusions The expressions of COX-2 is closely related to 5-LOX in UC patients. Both may play a pivotal role in inflammation of UC.

Hypoxia and hypoxia-induced factors (HIFs) are main regulators for tumor stem cells, metastasis-initiating cells and their differentiated progenies to adapt to the environment which lacks oxygen and nutrient in the process of cancer development. HIFs are up-regulated in many tumors, including leukemia, glioblastoma, melanoma, prostate cancer, breast cancer and pancreatic cancer, in where they are especially highly expressed in hypoxic regions. HIFs activation can induce expression of numerous stem cell related genes and multidrug resistance genes, which may play important roles in tumour and stem cell-mediated self-renewing, energy metabolism alternation, invasion, metastasis, angiogenesis and treatment resis?tance of neoplastic cells. Consequently, it will provide new clues for cancer therapy after investigating the role of HIFs in tar?geted regulation and metabolic pathway modulation in various stem cell-mediated tumor cells.
