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.

OBJECTIVEAn accurate and reliable analytical method for-simultaneous determination of six active components (scopolin, chlorogenic acid, scopoletin, isochlorogenic acid A, isochlorogenic acid B and isochlorogenic acid C) in plants of Erycibe was developed.

METHODScopolin, chlorogenic acid, scopoletin, isochlorogenic acid A, isochlorogenic acid B and isochlorogenic acid C in the samples were well separated in analytical HPLC by gradual elution with methanol-0.1% formic acid solution. The chromatographic condictions: Agilent Poroshell 120 EC-C18 column, flowing rate being 1 mL x min(-1), detecting wavelength at 345 nm.

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 investigate the hepatoprotective effect of silybin-phosphatidylcholine complex(SPC) in sepsis rats.Me-(thods) Fifty Wistar immature rats were randomly divided into 3 groups:normal control(10 cases),septic group(30 cases) and interfe-(rence) group(10 cases).In septic group and interference group,rats were treated by cecal ligation and puncture(CLP).Meanwhile,the interference group was given SPC before 2 hours of CLP and after 2 hours of CLP.Blood of rats was taken from all groups to determine the levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1),alanine aminotransferase(ALT) and aspartate aminotransferase(AST) at varying intervals.Results The levels of serum TNF-?,IL-1,ALT and AST after CLP were significantly elevated in septic group compared with the normal control group(P
