OBJECTIVETo evaluate the curative effect and surigical skills of reconstruction intramedullary nailing in the treatment of ipsilateral femoral neck and shaft fractures.

METHODSFrom January 2007 to January 2013, 13 patients with ipsilateral femoral neck and shaft fractures were treated by reconstruction intramedullary nailing including 11 males and 2 females with an average age of 38.9 yeas old ranging from 25 to 53 years old. For femoral neck fractures,10 cases were basilar neck fracture, 3 were transcervical fractures and according to Garden classification,10 were type II, 2 were type III and 1 was type IV. For feormal shaft fracture, 5 were type I, 4 were type II, 3 were type III and 1 was type IV according to Winquist classification. The location of all 13 feormal shaft fractures were all in the uper 3/4 of the feormal shaft. Complications and postoperative function were recorded and evaluated.

RESULTSEleven patients were followed up for 23.45 months (12 to 36 months). Time from injury to operation was 5.9 days in average. Malunion of femoral neck fracture happened in 1 patient, nonunion of femoral shaft fracture happened in 2 patients. NO femoral head osteonecrosis, infection and malunion of femoral shaft fracture happened. According to Friedman-Wyman classification, 8 cases get good result, 2 get faii and 1 get poor.

Objective To establish the radiolabeling method for peptide K237 with 131I and investigate the biodistribution and therapeutic efficacy of 131I-K237 on nude mice bearing human lung cancer.Methods Iodogen method was used for labeling K237. The bioactivity of 131I-K237 was tested by human umbilical vein endothelial cell ( HUVEC ) proliferation inhibitory assay and the affinity of 131I-K237 was examined by competition binding studies. Twenty-five mice were divided into five groups randomly, including physiologic saline (group 1), K237 (40 μg) (group 2), 131I ( 11. 1 MBq) (group 3), 131I-K237 (K237 40 μg, 11. 1 MBq) intravenously ( group 4), and 131I-K237 ( K237 40 μg, 11.1 MBq) intratumorally (group 5). Injections were repeated at 15 d after the first injection. The tumor growth inhibition rate was calculated. Student's t-test and analysis of variance (ANOVA) were used for testing significant differences of data. Results The inhibition rate of HUVEC proliferation had no significant difference between radiolabeled K237 and unlabeled K237 ( (73.69 ± 5.36) % vs ( 62.68 ± 3.83 ) %, t = 1.67, P ＞ 0.05 ). The growth of transplanted lung cancer was inhibited by 75. 01 % in group 4, 78.99% in group 5, 31.15% in group 2 and 12.61% in group 3, respectively. The average tumor volume of groups 4 and 5 were significantly smaller than that of groups 1,2, and 3 ( F = 15. 233 and 13.611, respectively, P ＜0. 01 ). Conclusion 131I-K237 can be readily radiolabeled and it can effectively inhibit the growth of tumor in nude mice bearing human lung cancer.

This study on determination of leukemia-specific chromosomal abnormalities and their relationship with prognosis of childhood acute leukemia (AL) had an important significance for childhood acute leukemia. In recent years, the efficacy of treatment of childhood AL has been greatly improved, but relapse is still a main factor affecting prognosis. Treatment based on the risk stratification by cytogenetic abnormalities can improve the prognosis and survival rate. In the past 3 decades, the genetic techniques have developed rapidly and many new genetic abnormalities have been found. This review highlights the main chromosomal and genomic abnormalities of 3 common childhood AL, including B-cell precursor acute lymphoblastic leukemia (BCP-ALL), T-cell acute lymphoblastic leukemia (T-ALL) and acute myeloid leukemia (AML).
