MicroRNAs(miRNAs) are small mm-coding RNA molecules that post-transcriptionul-ly regulate gene expression. Advanced studies show that miRNA are involved in cancer. Even some scientists regard miRNAs as oncogenes or tumor associated genes. This review tries to have a brief introduction on the progress in the relationship between miRNAs and tumor's formation,development,diagnosis,therapy and prognosis in humans.

[Objective] To investigate internal fixation with locked plate and bone cement in treatment of long bone pathologic fractures due to metastatic carcinoma. [Methods]From February 2005 to February 2008, 15 patients suffering from pathologic fractures caused by metastatic lesions of the humerus(3 cases), ulna(2 cases), radius(1 cases), femur(5 cases) and tibia(4 cases) have been surgically treated with internal fixation with locked plate and bone cement.[Results]All patients were followed up after operation for ranging from 24~46 months. Pain relief was achieved in 14 patients(93.3%). Thirteen(86.7%) patients got excellent Enneking scores at 2 weeks postoperatively. The quality of life had significant difference betwen before and after operation (P

ObjectiveTo explore the correlation of unknown gene AI408225 and humoral immunity involved in rat regenerating liver. MethodsIsolation of rat 8 liver cell types, detection of their genes expression change were accorded to Percoll density gradient centrifugation combined with immune magnetic beads separation method, and their genes sequence homoeology and coexpression relation were analyzed by Microsoft Excel, BLAST software, and the prediction physiological activities were analyzed by bioinformatics and systematic biology. Results A total of 93 humoral immunity-ass ociated genes yielded the meaningful expression changes in liver regeneration, the corresponding gene numbers in 8 liver cell types included hepatocytes, bile duct epithelial cells, oval cells, hepatic stellate cells, sinus endothelial cells, Kupffer cells, pit cells and dendritic cells were 33, 46, 17, 59, 48, 35, 53, 68. Among that AI408225 and cd4 are homology and coexpression.Conclusion The rat liver regeneration is closely associated with humoral immunity, and AI408225 participates in the formation of compound of MHC II-antigen peptide-CD4-TCR.

Objective:To give the test in cases of changing the conditions of measurement and reference value, compare the test results, and detect the capacity of QuickCheck, so as to offer reference for the daily morning check of accelerator and the evaluation of test results. Methods:Change the output dose, field size, SSD, angle of collimator and gantry angle of the accelerator, and then evaluate QuickCheck’s capacity of monitoring accelerator accordingly. Compare the field parameters measured by QuickCheck with the data from the 3D water tank. Results:When the output dose was 1 cGy higher than the reference value or 6 cGy lower than it, the field size expanded or contracted more than 2 cm simutaneouly, SSD was 2 cm higher or 1 cm lower than reference value, the collimator rotated more than 2 °, the gantry angle rotated more than 6 °, and then the test results of QuickCheck surpassed threshold. Comparing the measuring results of QuickCheck with 3D water tank, the difference between the flatness of the two was 3.84%, symmetry (G/T) 0.67%, symmetry (L/R) 0.47%and dose rate 1.2 MU/min. Conclusion:QuickCheck is rather accurate in testing the output dose, field size, angle of collimator, flatness, symmetry and dose rate, so it could meet the requirement of accelerator’s daily QA. However, its capability is relatively poor on examining SSD and the deviation of gantry angle.

2 cm). All patients received combination chemotherapy of abdomen and vein with CAP regime and TP regime after sections.Results:Total five year survival rates were 11% in epithelial ovarian carcinoma in stage Ⅲ. The 1-.3-.5-year survival rates of the cases which had less than 4 cycles of chemotherapy were lower than those ≥6 cycles, and the recurrent rates were higher than those ≥6 cycles. The 1-.3-.5-year survival rates of TP regime were higher than those of CAP regime,and the recurrent rates were lower than those CAP regime.Conclusions:There are many relationships between prognosis and residual tumor, nucmber of chemotherapy cycles or regime after resection,which influence results of recurrent ovarian cancer after repeated tumorectomy.

[Objective]To explore the clinic results of the locking compression plate fixation for the acetabular fractures.[Method]Twenty-three patients were treated in the author's department, 16 of them were male and 7 were female patients.The ages ranged from 21 to 61 years, and mean age was 43.3 years.Ninteen patients had been injured in an automobile accident,3 were fell from height and 1 was crushed by a heavy object. The patients were classified according to Letournel classification.There were 7 anterior column fractures,3 posterior wall fractures,5 anterior wall fractures,2 transverse fractures,1 anterior column and posterior column fracture,1 T shape fracture, 3 posterior wall and posterior column fractures,1 transverse and posterior wall fracture.[Result]All the incisions healed during the primary procedure and all the patients were available at follow-up ranging from 3 to 24 months(average 20.1 months).The average intraoperation time was 123 minutes(50～235 minutes),and the intraoperative blood loss was 100 to 1500 ml.The patinents underwent blood transfusion from 0 ml to 1 200 ml.According to Matt's criteria, the rate of excellent and good was 73.9%(17/23).[Conclusion]The locking compression plate fixation is one of the effective methods for treatment of acetabular fractures, with the advantages of being simple and minimally traumatic.

Objective To outline the characteristics of fractures of the coronoid process of the ulna in children and distinguish them from that of the adult. Methods Twenty eight cases of fractures of the coronoid process of the ulna in children in the past five years were reviewed. There were 18(64%) boys and 10(36%) girls. According to the extent of involvement, the fractures were classified as 3 types based on modified Regan and Morrey method. Of those, 10 cases were associated with other injuries such as dislocation of the elbow, fracture of the radial neck, fracture of the olecranon and so on. In this series, open reduction and internal fixation were applied in only 2 cases with type Ⅲ injury and conservative treatment including immobilization of the elbow in flexion with long arm plaster splint were done in all of the rest cases. Results Seventeen patients were followed up for an average of 14 months(range, 4 months to 5 years). The clinical results were evaluated according to pain, range of motion, muscular strength and stability of the elbow. The overall excellent result were achieved in 94%of the patients. No complaint and late complication were found in this series. Conclusion There are some obvious differences in the coronoid process fracture of the ulna between children and adult: 1)fewer cases associated with dislocation of the elbow in the children than in the adult; 2)the clinical results were relatively better in children than that in the adult whatever the surgical or conservative treatment was performed; 3)the prognosis of fractures of the coronoid process of the ulna was better and the complications were less in children than that in the adults.
