Gastrointestinal stromal tumors(GISTs) are rarely one of gastrointestinal carcinomas that originate from mesenchymal tissue.GISTs are characterized by expression of CD117 receptor in cells and have variable biological phenotypes ranging from benign to highly malignant.The most common complaints of patients with GISTs are abdominal pain,peptic ulcer,bleeding or/and obstruction in digestive tract.GISTs have an extraordinarily high rate of recurrence after surgical resection and are highly resistant to radiation and standard chemotherapy.The imatinib mesylate(Gleevec) is a selective inhibitor of the tyrosine kinase receptor.The outcome for the patients with GISTs treated by Gleevec was promising in terms of immediate response and survival fraction.Recent research shows that a new targeting therapeutic agent,SU11248,can prolong the survival time of the patients with GISTs who were resistant to Gleevec therapy.

The hydride generation technique was used to determination of germanium in the presence of L-cysteine.The GeH4 was absorbed and coloured by a mixed solution of 2-(5-NO2-2-pyridylazo)-5-diethylaminophenyl(5-NO2-PADAP),NaClO and (CH2)6NH+.The maximum absorption of the colour complex was at 564nm.Its apparent molar absorption coefficient was 1.84×105L·mol-1·cm-1.Beer＇s law was obeyed for 0～500μg/L germanium.The recoveries of spiked samples were in the range of 89%～97%,while the relative standard deviation was less than 6.3%.This method is sensitive,simple and reproducible.The method has been applied to the determination of Ge in the chinese medicine with satisfactory result.

Objective To investigate the values of urine neutrophil gelatinase associated lipocalin (NGAL), kidney injury molecular-1 (KIM-1) and interleukin-18 (IL-18) in the diagnosis of acute kidney injury (AKI) in children after cardiopulmonary by-pass (CPB). Methods Sixty-seven patients who had undergone CPB were recruited from March to June 2013 and assigned to acute kidney injury group (AKI group) or non-acute kidney injury group (non-AKI group) according to the pediatric RIFLE (pRIFLE) cri-teria. Serum and urine samples were collected from each patient at 30 min, 2 h, 4 h, 24 h, 48 h and 72 h after CPB for serum and urine creatinine, urine NGAL, KIM-1 and IL-18. All the data were evaluated by receiver operator characteristic curve (ROC) analysis and area under curve (AUC) analysis. Results Twenty-three cases (34.3%) had AKI in 67 children after CPB. Among them 15 cases were risk-stage AKI, 4 cases injury-stage AKI, 3 cases failure-stage AKI and 1 cases loss-stage AKI. The levels of urine NGAL/Ucr were higher in AKI group than those in non-AKI group at 4h, 48h and 72h after CPB (P<0.05). The cut-off value of NGAL/Ucr was 1.200 at 4 h after CPB, the sensitivity and specificity for prediction of AKI were 0.864 and 0.561, and the AUC was 0.671 (95%CI:0.537-0.804). The levels of urine KIM-1/Ucr were higher in AKI group than those in non-AKI group at 48h and 72 h after CPB (P<0.05). The cut-off value of KIM-1/Ucr was 1.162 at 24h after CPB, the sensitivity and specificity for prediction of AKI were 0.773 and 0.512, and the AUC was 0.698 (95%CI:0.563-0.834). The levels of IL-18/Ucr were higher in AKI group than those in non-AKI group at 4 h after CPB (P<0.05). The cut-off value of IL-18/Ucr was 0.04 at 4 h after CPB, the sensitivity and specificity for predici-ton of AKI were 0.773 and 0.561, and the AUC was 0.655 (95%CI:0.510-0.800). Conclusions It is indicated that urine NGAL, KIM-1 and IL-18 may have important clinical values for early prediction of AKI.

Objective To explore the distributional differences of the gene frequencies of 22 short tandem repeats loci on Y Chromosome(Y?STRs) between offenders with Initiative?aggressive behavior and impulsive?aggressive behavior,and to probe into the genetic factors of initiative?aggressive behavior and im?pulsive?aggressive behavior. Methods Biological samples of 271 offenders with initiative?aggressive behav?ior and 271 offenders with impulsive?aggressive behavior were collected and PCR compound amplification was carried out with the aid of PowerPlex Y23 System. Then the PCR products were subjected to electrophoresis and gene detection with AB3500xL gene analysis system so as to calculate and compare the alleles and haplo?types of 22 Y?STRs gene frequency in the two groups. Results The distribution of allele frequency were sig?nificantly difference in locus DYS437(P=0.022) between two groups,not in the other 21 Y?STRs loci( all P>0.05) . Univarite analysis showed significant differences at allelle 14 in locus DYS437 between both groups ( initiative?aggressive behavior group:69. 37%;impulsive?aggressive behavior group:58. 67%; P=0. 009 ) . Conclusion Loci DYS437 may be associated with aggressive behavior. In the group of aggressive behavior, allelle 14 on locus DYS437 may be the susceptible factor of initiative?aggressive behavior and the resistant factor of impulsive?aggressive.
