Conclusion Nurses should pay attention to the psychological conditions of pregnant patients with gynecologic malignancies and help them successfully live through the treatment.

Objective To study the diagnosis and operation timing of acute mesenteric ischemia(AMI).Methods A retrospective analysis based on the clinical characteristics,the methods of diagnosis and treatment,and operative results of 21 patients with AMI admitted in our hospital from January 1997 to December 2007 was performed.Results The diagnosis were certified by color doppler ultrasonography in five cases,spiral CT in eleven cases,DSA in two cases,and abdominal exploration in three cases.One case was cured by anticoagulation /thrombolytic therapy;and one case was confirmed with selective vascular angiography and cured by urokinase perfusion via the catheter;after removing the thrombus followed by anticoagulation /thrombolytic via Fogarty balloon catheter,ischemia of intestine completely recovered in three cases,partial small bowel resection were performed in eight cases,"second-look" operation in two cases,and subtotal small bowel resection in six cases.Three cases developed short-gut syndrome and three cases died after operation.Conclusions Imageological examination is essential for diagnosis of doubtful cases of AMI,and adequate treatments and timely selection of operation are critical to attain early diagnosis and good results.

Objective:To evaluate the masking ability of the Rely XTM Veneer try-in pastes. Methods: 100 discolored teeth, including 50 nonvital ones and 50 vital ones, has been collected and restored respectively with all-ceramic crowns and veneers. Five try-in pastes including A1, A3, Translucent (Trt), White opaque(WOT) and B0.5 Opaque(B0.5),which were different in shade, were used to try in before adhesion. The color was measured by a digital colorimeter, and expressed in terms of 3 coordinate values(L*、a*、b*) of the CIE1976- L*a*b* system.Then the color differences of crowns and veneers ?E=[(?L*)2+(?a*)2+(?b*)2]1/2 as well as the value of Light (L= L*)、Chroma[C=〔(a*)2+(b*)2〕1/2] and Hue [H=arctan(b*/a*)] were calculated. The thickness of the measurement point was also measured and recorded. A one-way ANOVA was used to analyze ?E as well as L, C and H. Results:The chromatism of the veneers after try-in was higher than that of the crowns(P

Objective To investigate the correlation of CT image features of mesenteric fibromatosis and its pathological characteristics.Methods Data of 12 mesenteric fibromatosis proved histopathologically in PLA General Hospital and Jiangsu Taizhou People's Hospital from March 2006 to March 2015 were retrospectively reviewed.Results There were 5 males and 7 females with ages ranging from 13 to 67.On the CT image,the masses varied from 3.9 cm to 33.0 cm in diameter.8 of them were round or oval well-circumscribed masses,and 4 were irregular with blurry border.10 of 12 cases were totally similar density,which was ranged from 27 HU to 39 HU.Contrast enhanced CT scan showed moderate enhancing masses in l0 of 12 cases.Macroscopic examination of these specimens revealed that the sections of 11 were solid,firm,grey and yellowish,and 1 was solid-cystic.On the histopathology,the masses consisted of homogeneous spindle shaped fibroblasts,myofibroblasts and collagen.Tumor cells were embedded in a collagen network interrupted by fibrotic sections.Immunohistochemical analysis revealed that the tumor cells expressed Vimentin,H-caldesmon and β-catenin.Conclusions Mesenteric fibromatosis is a rare disease with characteristic CT images,which were based on their pathological characteristics.CT images form the basis of preoperative diagnosis of this disease.

Objective To investigate the effects of high-fat diet on the formation of colorectal adenomas in rats.Methods Twenty Wistar rats were evenly divided into two groups,one group were fed with common food and the other group were fed with high fat-diet.The rats of two groups were intraperitoneally injected with 1,2-dimethyl-hydrazine (DMH) (40 mg/kg) once a week for 10 consecutive weeks.Rats with common diet and DMH were assigned to SDT group,and those with high-fat diet and DMH were assigned to HFDT group.The expression of Ki-67 was detected by immunohistochemistry and the expression of proliferating cell nuclear antigen (PCNA) and cyclooxy-genase 2 (COX2) was detected by immunofluorescence.The levels of serum triglyceride,cholesterol,insulin like growth factor-1 (IGF-1),insulin,leptin and tumor necrosis factor-α were determined by enzyme linked immunosorbent assay.Student's t test and Mann-Whitney test were performed for statistical analysis.Results At the 18th week,the numbers of Ki-67 positive cells of SDT group and HFDT group were 24.00± 1.84 and 75.17 ± 3.17,respectively,and the difference was statistically significant (t=13.960,P＜0.01).The fluorescence intensity of PCNA of SDT group and HFDT group was 213.70±21.61 and 333.30±30.44,respectively,and the difference was statistically significant (t =4.987,P＜0.01).The levels of serum triglyceride of SDT group and HFDT group were (0.43 ± 0.05) mmol/L and (1.14±0.07) mmol/L,respectively,and the difference was statistically significant (t=8.366,P＜0.01).The levels of cholesterol were (3.75±0.'26) pmol/L and (7.77±0.79) pmol/L,respectively,and the difference was statistically significant (t=4.851,P＜0.01).Conclusion High-fat diet can promote the genesis and development of adnomas through influencing the body's endocrine metabolism,increasing cell proliferation cycle and regulating inflammatory reaction.

AIM:To study the effect of contact system in monocyte adhesion induced by urokinase-type plasminogen activator (U-PA). METHODS:U937 cells were labeled with [3H] thymidine in the culture medium, test reagents were added into the cell suspension in 24-well plates. The counts?min -1 were counted in a liquid scintillation counter. RESULTS:U-PA-induced monocyte adhesion was inhibited by high-molecular-weight kininogen and kallikrein, and promoted by factor Ⅻ and plasminogen. CONCLUSION:these contact system proteins may be important modulators of U-PA-induced monocyte adhesion, a process which is involved in many pathophysiological events.

ObjectiveTo study the expression of AKT2 gene in liver cancer and its relationship to tumor progression.MethodsThe expression of AKT2 in liver cancer was detected by SP immunohistochemical stainin and reverse transcription polymerase chain reaction (RT-PCR).Four patients with benign liver tumors were used as control.ResultsThe positive rates of AKT2 in liver cancer tissue and benign control tissue were 62.5％ (28/32) and 0％ (0/4),respectively.The difference was significant.In addition,a positive expression of AKT2 correlated significantly with poor differentiation,positive lymph node and distant metastasis.The median survival after surgery was significantly shorter in patients with positive than with negative AKT2 (76d vs 463d).ConclusionThe detection of AKT2 was useful in assessing the progression of liver cancer,in determining prognosis and eventually in rendering a possible target for novel therapeutic strategies.

Objective To investigate the surgical management of unsuspected gallbladder carcinoma (UGC) after laparoscopic cholecystectomy ( LC ). Method The clinical data of 11 cases of UGC incidently found after LC from October 2003 to August 2009 were retrospectively analyzed. Results According to Nevin staging, 2 cases were stage Ⅰ , 6 cases were stage Ⅱ , 2 cases were stage Ⅲ and 1 case was stage Ⅳ.Four cases were treated by LC,including 2 cases with stage Ⅰ and 2 cases with stage Ⅱ ;another 7 cases were treated by radical resection after LC. All patients were followed up for 1-66 months after operation, 2 cases with stage Ⅰ were observed alive up; 2 cases with stage Ⅱ treated by LC died less than 3 years after operation, 3 of the 4 cases with stage Ⅱ treated by radical resection were alive up, only 1 died in 21 months after operation; 2 cases with stage Ⅲ died in 8 months and 10 months respectively, 1 case with stage Ⅳ died in 1 month after operation. Conclusions It is difficult to diagnose the UGC preoperatively. LC is sufficient for patients with Nevin stage Ⅰ , radical resection after LC is required for patients with stage Ⅱ or more advanced stage. If tumors are located in the neck of gallbladder, radical resection is required regardless of their stage.
