Objective:To examine the expression of TRAF 6 in ovarian carcinomas ,discuss the relation between expression level and clinical characteristics of ovarian carcinomas and study the clinical significance .Methods: Specimens from 102 patients with ovarian carcinomas managed in our hospital between Augest 2001 and December 2009 were included in this study .Immunohistochemical staining was used to detect the expression of TRAF 6 in ovarian carcinomas and normal tissues .All the specimens were confirmed by pa-thology for ovarian carcinomas and normal tissues by HE staining .Then, the correlation between the expression and clinical characteristics of patients was analyzed .Furthermore ,survival analyses were performed according to the Kaplan-Meier method.Results:The positive expression rate of TRAF 6 in ovarian carcinomas and normal tissues was 68.6% and 20.5%, respectively.TRAF6 expression was significantly associated with tumor stage and distant metastasis ( P<0.05 ) .According to the survival analysis of 102 ovarian carcinomas patients ,cases in the TRAF6 low-expression group showed poorer overall survival rate when compared with low -expression group ( P<0.001 ) .Conclusion: These results indicate that the expression of TRAF 6 was closely related with in the progression of ovarian carcinomas and may have clinical utility in the prediction of prognosis of ovarian carcinomas .

Angiogenesis plays a very important role in the development and metastasis of breast cancer. Low-dose metronomic chemotherapy based on the traditional chemotherapy drugs has antiangiogenic effect. As far as its mechanism, low toxicity or low incidence of drug resistance is concerned, it is feasible for breast cancer therapy. It displayed the validity and feasibility in the pre-clinical studies and clinical trials, which provided a new treatment strategy for the breast cancer.

OBJECTIVE To investigate the effect of repeated debridement on the efficacy of endoscopic sinus surgery(ESS). METHODS A total of 67 patients underwent ESS were divided into intervention group and control group. Debridement was performed at the 1st, 4th, 8th week after operation for the patients in intervention group, while once per week for the patients in control group. The primary outcome measure was visual analogue scale(VAS)and Lund-Kennedy endoscopic score(LKES). RESULTS Comparing the two groups on all domains of digital VAS and LKES at the 4th, 8th week after operation, there were no significant difference between the two groups. CONCLUSION Benefit of frequent debridement during the early postoperative period was no positive correlation with patients recovering after ESS. Therefore, in terms of subjective recovery and health care costs,appropriate extending postoperative management time and decreasing intervention frequency do not decrease the efficacy of endoscopic sinus surgery.

Objective:To study the effect of recombinant human growth hormone(rhGH) and its combination with chemotherapy(5-FU) in tumor bearing mice.Methods:Hepatic metastases model were established in 615 mice by splenic injection of proventriculus squamous carcinoma cell(MFC).Among them,sixty mice were divided randomly into 6 groups(ten per group): control(NS),GH1,GH2,flurouracil(5-FU),flurouracil plus rhGH(GH1+5-FU) and flurouracil plus rhGH(GH2+5-FU).Body weights were measured every week.On the 28~(th) day,animals in each group were executed.The weight of body and liver was measured,and cell cycle of tumor DNA was determined by flow cytometry(FCM). Other 48 animals were divided randomly into 6 groups(eight per group) and treated with the same methods as above.They were fed till death to observe survival time. Results:Body weights in the GH1+(5-FU) and the GH2+5-FU group were increased than that of control group(P

Objective To compare the effect of scapula lateral margin approach and standard Judet approach in the operative treatment of scapular fracture. Methods Medical data of 48 patients with scapular fractures from January 2006 to February 2013 were retrospectively analyzed. They were divided into the observation group and the control group according to the surgical approach. 27 patients in the observation group were treated with operative treatment through scapula lateral margin approach and 21 patients in the control group were treated with sur-gical treatment through standard Judet approach. Compared the clinical effects and complications of the patients in two groups. Results To operation time and intraoperative hemorrhage in the observation group were less than that of the control group (P<0. 05),fracture healing time was shorter than that of the control group after operation (P<0. 05). Six months after operation,the excellent rate of the observation group was higher than that of the control group. Scores of daily activities and myodynamia in the observation group were higher than that of the control group,the differences were statistically significant(P<0. 05),and there was no significant difference in the scores of pain and joint motion between the groups(P>0. 05). Conclusion Scapula lateral margin approach in treatment of scapular fracture has the advanta-ges of easy operation,small trauma,definite effect,little complication and it can be used as the preferred scheme of scapular fracture operative treatment.

Hepatic artery stricture (HAS) after liver transplantation can lead directly to transplanted liver function exhaustion and complications of biliary system. The early diagnosis and treatment are crucial for better prognosis. Doppler ultrasound is the first method of choice, and angiography can give further clear dignosis. The balloon dilatation is still effective for hepatic arterial stenosis. With the more adaptable usage of oronary stent, if possible, would reveal more promising result especially for tortuous stenotic hepatic artery. The vascular reconstruction or repeated liver transplantation is still the effective therapeutic methods.

BACKGROUND:Previous studies have applied long-bone mechanical separation method to obtain osteoclasts, which are terminal y differentiated cells and cannot further proliferate. Therefore a large number of osteoclasts can be harvested with bone marrow cells inducing culture method and RAW264.7 cells inducing culture method to meet clinical requirements.
OBJECTIVE:To investigate the optimal method of receptor activator of nuclear factor kappa-B ligand (RANKL) induced osteoclast precursors to differentiate into mature osteoclasts.
METHODS:After bone marrow cells were isolated from mouse, RANKL and macrophage colony stimulating factor were added into the medium together, or RAW264.7 cells were cultured with RANKL to induce osteoclasts. The osteoclast precursors were treated with different concentrations of RANKL to observe the number of generated osteoclasts and evaluate the dose-effect relationship between RANKL and osteoclastogenesis. Annexin V-FITC and propidium iodide staining were used for flow cytometry to analyze the mononuclear-macrophage apoptosis during osteoclastogenesis.
RESULTS AND CONCLUSION:When 10μg/L RANKL was used, the peak of osteoclastogenesis appeared at days 6-7;when the concentration of RANKL was up to 100μg/L, the peak appeared at days 4-5. The number of new osteoclasts was dose-dependent on the RANKL concentration. 50μg/L of RANKL was the turning point in the fitted curve from osteoclastogenesis and RANKL concentration. After the RANKL concentration was more than 150μg/L, the number of osteoclasts slowed down obviously. RANKL can induce monocyte-macrophage to form osteoclasts and promote monocyte-macrophage apoptosis. The highest number of osteoclasts would be obtained to each unit of RANKL when monocyte-macrophage cells were cultured with 30μg/L of RANKL in the same vaccination density (104/cm2). Experimental findings indicate that, RAW264.7 cells or bone marrow cells inducing culture methods are simple and feasible, the optimum cellseeding density was 104/cm2;the appropriate stimulation concentration of RANKL was 30-50μg/L.
