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.
CONCLUSIONReconstruction intramedullary nailing is a good choice for the ipsilateral femoral neck and shaft fractures with the advantages of less soft-tissue trauma and complications.

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.
5.Progress of studies on genetics of childhood acute leukemia.
Journal of Experimental Hematology 2013;21(3):791-795
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).

Objective To investigate the value of serum concentration of VEGF-C in the prognosis of advanced pancreatic cancer. Methods Thirty-five patients with advanced pancreatic cancer were selected from Aug. 2006 to Feb. 2008, ELISA method was used to detect the serum level of VEGF-C, CA19-9 and KPS score was calculated, and survival was analyzed by Kaplan Meier method. The survival difference was calculated by log rank. Cox regression model was used to perform univariate and multivariate analysis. Results The mean serum concentration of VEGF-C was ( 1309 ± 542 ) pg/ml in patients with advanced pancreatic cancer, which were significantly higher than that those in normal control [ (278 ±115) pg/ml, P <0.01 ]. In Cox regression, KPS score, serum CA19-9 and VEGF-C were independent factors (x2 =7.208, 6.908, 3.867, P = 0.007, 0.009, 0.049). In multivariate analysis, serum VEGF-C and KPS score were independent factors (x2 =4.873, P=0.027, x2 =5.274, P =0.022). Using serum concentration of VEGF-C at 1280 pg/ml as the cut-off point, the mean survival of patients with VEGF-C ≤1280 pg/ml was 10.0 months, and the median survival was 11.3 months, 1 year cumulative survival was 50.0% ; while they were 6.0 months, 6.3 months and 5.9% in patients with VEGF-C > 1280 pg/ml, and the difference was statistically significant (x2 = 9.400, P= 0.002). Using KPS score 70 as the cut-off point, the mean survival of patients with KPS <70was 6.0 months, and the median survival was 6.6 months, 1 year cumulative survival was 21.4% ; while they were 9.0 months, 10.1 months, 33.3% in patients with KPS score ≥70,and the difference was statistically significant (x2 =4.040, P =0.044). The difference of the median survival, 1 year cumulative survival in patients with CA19-9 ≤200 U/ml or >200 U/ml was not statistically significant (10.0 months vs. 7.8 months, 37.5% vs. 21.1% ; x2 =1910, P=0. 167). Conclusions Serum concentration of VEGF-C can used as an independent factor for predication of prognosis of patients with advanced pancreatic cancer.

Objective To evaluate the effects of adeno-associated virus-enhanced green fluorescent protein (AAV-EGFP)on the biologic behavior of rabbit's bone marrow stromal cells(BMSCs)by means of a simple method of culturing and osteogenic induction in vitro so as to find an ideal viral vector and cell tracing mark for tissue en- gineering.Methods Total bone marrow culture was conducted to obtain rabbit BMSCs which were then induced in the osteogenic direction.The morphology of the cells was observed continuously,and their surface antigen and ossification were detected by alkali phosphatase stain and Von Kossa stain.On the basis of the above results, AAV-EGFP was transfected into the induced cells.The morphologic changes of the cells,the expression time and intensity of fluorescent light were observed.The transfection efficiency was detected to find the best multiplicity of infection(MOI)value.The cell growth curves were drawn to evaluate the biologic effects of AAV-EGFP on the cyto-activity.Results The morphology and purity of the rabbit BMSCs obtained were good.The ossification of the cells was significant after osteogenic induction.The best MOI value was found to be 1?10~5.The expression intensity of fluorescent light was strong with the expression time more than eight weeks so that the fluorescent light could be observed after cell generations.The transfection efficiency of AAV was high without significant biologic effects on the cyto-activity.Conclusions The total bone marrow culture and in vitro cell induction can satisfy the requirements for seeding cells in tissue engineering.AAV is an ideal viral vector for tissue engineering.Transfection of AAV-EGFP to cells could be an ideal method for cell tracing mark.

In order to obtain an efficient screening procedure for identification of succinate producing anaerobic strains,a semi-quantitative paper chromatography method was developed. Lactic acid and acetic acid were identified as the main byproducts in the process of succinate production by the high performance liquid chromatography (HPLC).Succinic acid was completely separated from the byproducts of lactic acid and acetic acid in the same broth developed by paper chromatography.The content of succinic acid was calculated by a semi-quantitative method.The results showed that paper chromatography was a simple and cost effective method that could be utilized to screen anaerobic strains producing succinic acid.
