The effect of Fusarin C, a new mutagen extracted from Fusarium moniliforme,on murine peritoneal M? activation by measuring M?-mediated MTC ADCC and CS,Fusarin C could inhibit M? activation by both MAF and FDP. The inhibitory effect was dose-and time-dependent and the curves of dose-and time-response were similar in all three assays. There is, however, apparent difference in Fusarin C dose and time needed to induce significant in hibition among these assays. Significant inhibition occured at 0.4?g/ml and 0.5?g/ml for MTC and CS respectively, but 1.6?g/ml for ADCC. Similarly, the minimal period of time necessary to bring about significant inhibition was 2 hr for MTC, but 3 hr for ADCC. Finally, significance of the inhibitory effect of Fusarin C on M? anti-tumor activity in relation to carcinogenesis was discussed.

The inhibitory effect of Fusarin C,a new mutagen isolated from Fusarium moniliforme,on M? activation was investigated.The inhibitory effect of Fusarin C disappeared partially after 24 hr culture in the absence of the mycotoxin and completely after 72 hr.In addition,it could be overcome by high concentrations of M? activating factor or anti-serum to the target cells.

Objective To study the neuropsychological behavior development of preterm infants and low birth weight infants,and to provide a reference to the early prevention and intervention on developmental retardations.Methods A total of 101 preterm infants and/or low birth weight infants received the infant development test of 0 ～ 6 year-old children intelligence developmental scale for neurological development and autism behavior checklist(ABC).Results 25 boys and 5 girls suffered from different psychological mental disorders.The occurrences were as follows:10 cases with mental retardation,9 cases with the language development delay,9 cases with motor retardation,1 case with cerebral palsy and 1 case with autism spectrum disorder.The incidence of intelligence problems were that language retardation (18.9％),the fine motor (16.8％),the adapative ability (12.6％),social action (9.5 ％) and the motor delay (3.2％).There were significant differences in the scores of social communication(x2=8.88,P=0.003),adaptive ability(x2=7.41,P=0.007),the fine motor(x2 =6.22,P=0.01) and total developmental quotient(x2 =5.58,P=0.02) between city children'and rural area.The behavioral problems more consisted in self-care ability and language retardation.Conclusion Preterm infants and low birth weight infants are exposed to language,fine motor,adaptive and communication ability problems,especially the children living in country.It is necessary to improve the early education and intervention for the rural preterm infants and low birth weight infants.

Background:Fenretinide,which is capable of generating reactive oxygen species( ROS ),has emerged as a promising antineoplastic agent based on numerous in vitro and in vivo studies and clinical chemoprevention trials. Preliminary studies showed that fenretinide could induce apoptosis in human hepatocellular carcinoma( HCC)cells in vitro, however,the precise mechanism was not clarified. Aims:To elucidate the effect of ROS on apoptosis of human HCC cells induced by fenretinide and the underlying mechanism. Methods:Human HCC cell line Huh-7 was treated with antioxidant vitamin E,fenretinide or their combination,respectively. ROS in live cells was evaluated by confocal microscopy and flow cytometry;cell viability and apoptosis were assessed by CellTiter-Glo Luminescent Cell Viability Assay Kit and Caspase-Glo3/7 Assay Kit;expression and intracellular localization of nuclear receptor Nur77,as well as expression of stress-induced transcription factor GADD153 were measured by immunofluorescence staining and Western blotting,respectively. Results:Vitamin E pretreatment fully blocked the fenretinide-induced ROS production. In Huh-7 cells pretreated with vitamin E,cell apoptosis induced by fenretinide was significantly reduced(P<0. 05). Furthermore,effect of vitamin E pretreatment was noteworthy on reducing fenretinide-induced GADD153 expression, while no significant impact on fenretinide-induced Nur77 expression and translocation was observed. Conclusions:Elimination of ROS by vitamin E can abrogate the pro-apoptotic effect of fenretinide on Huh-7 cells,which indicates the participation of ROS in fenretinide-induced apoptosis of human HCC cells. Its mechanism might be associated with induction of GADD153 protein expression.
