BACKGROUND: There are disputes concerning limb salvage and reconstruction in treating pelvis malignant tumor.OBJECTIVE: To study the surgical treatment following resection of tumor at acetabular region in order to restore pelvic stability with less damage or recurrence.METHODS: Thirty-three patients diagnosed with pelvic tumor at Department of Orthopaedics, First Affiliated Hospital of Second Military Medical University from April 2002 to June 2008 were selected. All patients were received tumor resection and computer-aided prosthetic replacement, 18 patients (8 cases with chondrosarcoma, 2 cases with Ewing sarcoma, 2 cases with osteosarcoma, and 6 cases with malignant fibrous histiocytoma) were combined with antitumor drug treatment. Functional assessment of therapeutic efficacy was divided into 4 levels: excellent, good, moderate, and inferior.RESULTS AND CONCLUSION: Two patients died at months 4 and 6 after prosthetic replacement; 31 cases were followed-up for 8-32 months, mean 12.5 months. Seven cases were recurred chondrosarcoma, the recovery of other patients were as follow: 18 cases were excellent, 4 cases were good, 2 cases were moderate and no case was inferior. Most of limb function and pelvic stability was preserved. The results suggested that malignant fibrous histiocytoma and Ewing sarcoma can receive a high rate of limb preservation if treated by effective chemotherapy with low recurrence; the recurrence of chondrosarcoma was high. Tumor resection combined with computer-aided prosthetic replacement can maximatily reserve limb function and raise life quality.

AIM: This study is based on the result of the study in HL and ALCL employing gene chip technique, in which writer found that there was distinctly different expression of caspase-4 between HL and ALCL cell lines at the level of mRNA. From the point of view, we try to identify at the level of protein whether there is different expression of this gene in HL and ALCL tissues as well. METHODS: HE staining, the monoclonal antibodies CD30 (BerH2), CD15 (C3D-1), CD20 (L26) and CD45RO (UCHL1) were used for selecting the cases of HL and ALCL. Specific high affinitive anti-caspase-4 polyclonal antibody was used by immunohistochemical staining to analyze the expression of caspase-4 in 18 cases of HL and 15 cases of ALCL. RESULTS: The expression of caspase-4 demonstrated a strong positive staining in all ALCL cases (15/15,100%), whereas negative in 16 HL cases (88 8%), while other two cases were weakly stained (11 2%), showing a distinct difference (P

To design teaching course of problem-based learning (PBL) combined with case-based learning (CBL) for standardized training of clinicians based on clinical decision thinking mode (CDTM) of diagnosis and treatment process for primary liver cancer. The CDTM of treatment choice for primary liver cancer is multi-scheme selection model. The general decision rule includes decision condition, action plan and decision tree. For the theoretical study of clinical decision rules, it is suitable to design PBL teaching, but it is suitable to design CBL teaching course for clinical decision-making practice. The teaching course of PBL combined with CBL is conducive to improving the ability of clinicians' clinical decision thinking step by step.

Objective:To investigate the recognition and injury prevention strategies of hepatic artery variations during hepatic portal lymphadenectomy. Methods:A retrospective analysis was performed, and 12 patients of hepatic arterial variation among 62 pa-tients with hepatic portal lymphadenectomy were the subjects. The study was conducted in the First Affiliated Hospital of Bengbu Medi-cal College between January 2013 and July 2014. The intraoperative treatment and postoperative complications were recorded. Results:Among 12 cases of hepatic artery variation, we found the following cases:3 cases (25.0%) of Michels' Type III, 2 cases (16.7%) of Mi-chels' Type VI, 1 case (8.3%) of Michels' Type IX, 1 case (8.3%) of Hiatt's Type 6, 2 cases (16.7%) of spatial location variation between right hepatic artery and hepatic duct, 2 cases (16.7%) of left and right hepatic artery originating from a common hepatic artery, and 1 case (8.3%) of right hepatic artery originating from the gastroduodenal artery. No injury of hepatic artery occurred. Two cases had post-operative complications, including 1 case of pancreatic leakage and 1 case of incision infection;postoperative hemorrhage, bile leakage, hepatic abscess did not occur in these two cases. Patients recovered well in general. Conclusion:Hepatic arterial injury can be signifi-cantly reduced by the following:increased familiarity with the various types of hepatic artery variations;complete imaging examina-tions for inspection and evaluation before surgery;and careful and meticulous operations in surgery.

Objective:To investigate the relationship between the expression of serum exsomal miRNA-155-5p (miR-155-5p) and prognosis in patients with esophageal squamous cell carcinoma (ESCC).Methods:A total of 336 samples from ESCC patients in Fujian Provincial Cancer Hospital from October 2014 to December 2015 were collected. The relative expression levels of serum exsomal miR-155-5p were detected by using real-time fluorescent quantitative polymerase chain reaction (qRT-PCR). Cut-off value of the expression levels of serum exsomal miR-155-5p was determined by using X-tile software. Based on the optimal cut-off value, patients were divided into miR-155-5p low expression group and miR-155-5p high expression group. The survival curve was drawn by using Kaplan-Meier method and Cox proportional hazards regression model was used to make survival analysis.Results:The cut-off value of serum exsomal miR-155-5p expression level was 2.340. According to the cut-off value, patients were divided into miR-155-5p low expression group (<2.340) of 51 cases and miR-155-5p high expression group (≥2.340) of 285 cases. There were no statistical differences in age ( χ2 = 0.020, P = 0.887), gender ( χ2 = 0.283, P = 0.595), tumor location ( χ2 = 0.063, P = 0.977), differentiation grade ( P = 0.474), clinical staging ( χ2 = 3.996, P = 0.136) and surgery treatment ( χ2 = 0.941, P = 0.332) of patients in both groups. ESCC patients in serum exsomal miR-155-5p high expression had a higher risk of death compared with patients in miR-155-5p low expression group ( HR = 1.763, 95% CI 1.049-2.961, P = 0.032). Conclusion:The high expression level of serum exsomal miR-155-5p is associated with poor prognosis in ESCC patients and it could be used as a prognostic new marker in ESCC patients.
