The antitumor effect of sodium morrhuate (SM ) and cis - diaminoaichloroplatinum (CDDP ) for gastric cancer cell SGC - 7901 in vitro is observed with MTT assay. Human gastric cancer cells line SGC - 7901 were inoculated subcutaneously in the naked mice , so xenografts were established. The tumor of the mice in the combination groups were cross injected with SM 50mg . kg~(-1) . time~(-1) , 50?l and CDDP ( 3mg ? kg~(-1)? time~(-), 50?l)in varying order at an interval of 30 minutes. In each mouse the tumors were injected every third davs for a total of three injections. lt was found SM had strong antitumor effect on gastric can- cer cells in vitro experiment. The antitumor effect of local injection in combination groups were much stronger than that in any other single drug groups. The histopathological section observation showed that all tumors cells were necrotic in combination groups, There could be seen fibrous histocysts around the . necrotic tumor tissue in observation groups , and necrotic vascular endotheliocytes. The experiment showed that combined injection with SM and CDDP had a synergic antitumor effect.

Objective To study the changes of oxidative stress and caspase-3 in swine with traumatic hemorrhagic shock in dry-heat environment of desert.Methods A total of 48 Landrace small swine were randomly(random number)divided into 2 groups(n=24 in each group), and then the traumatic hemorrhagic shock was established in room temperature environment and in dry-heat environmentin swine.Dry-heat environment traumatic hemorrhagic shock group (DHS), which was made in an artificial experiment cabin mimic the reality included swine exposed in the dry-heat environment of desert for 3 h (T0, n=6), T1 (50 min after shock modeling, n=6), T2 (100 min after shock modeling, n=6), T3 (150 min after shock modeling, n=6).At each interval, blood sample was collected to detect urea nitrogen (BUN) and creatinine, urine sample was collected to detect neutrophil gelatinase-associated lipoprotein (NGAL), kidney tissue samples were collected to evaluate renal morphological and tubular scores, as well as to detect catalase (CAT), superoxide dismutase (SOD) and malondialdehyde (MDA).Western blot was used to detect the level of caspase-3.Traumatic hemorrhagic shock group of room temperature environment (RTS) was established and variety of assays were carried out as same as those deteced in the dry-heat environment group.Results Compared with the room temperature environment exposed group,kidney damage index, antioxidant and caspase-3 were increased in desert dry-heat environment exposed for 3 h group, but there were no statistically significant difference(P> 0.05).And from T1 then on, the levels of NGAL, CAT and SOD in DHS groups were increased which were significant different from those in RTS group (P<0.05 or P<0.01).There were significant differences in BUN and creatinine at T2 between two groups(P<0.05).At T3, caspase-3 protein content in DHS group was significantly different from that in RTS group (P<0.01).Correlation analysis showed that the NGAL level was correlated with the levels to MDA (rRTS=0.935, rDHS =0.858, P<0.01) in RTS group and DHS group.Compared with RTS group, renal tissue under light microscope showed that Bowman appeared dilated with degeneration and exfoliated epithelial cells, proximal tubule epithelial shedding, and interstitial edema in DHS group.Electron microscope showed that mitochondria became pleomorphic, endoplasmic reticulum with fold broadening.Conclusions When traumatic hemorrhagic shock happened in the desert dry-heat environment, desert dry-heat environment can aggravate kidney damage, possibly by reducing the renal tissue antioxidant enzyme content and increase renal tissue caspase-3 activity to promote renal tissue apoptosis.Antioxidant stress and apoptosis may be an important role in the prevention of the secondary kidney injury induced by traumatic hemorrhagic shock in dry-heat environment.

Objective To explore the role of tumor inhibition of enhancer binding protein C/EBPα in the leukemic mice. Methods BALB/c nude mice were randomly divided into three groups. Three kinds of cells including pEGFP-C/EBPα-K562 cells, pEGFP-K562 cells and K562 cells as the control were injected into mice separately through the subcutaneous and tail vein, and subcutaneous tumors and leukemic models were formed. The changes of tumors were observed and the apoptosis of cells was detected by TUNEL; The capacity of proliferation of leukemia cells was observed in the bone marrow and the peripheral blood by Wright-Giemsa staining. The expression of genes of related to proliferation was detected by RT-PCR. Results The quality and the max diameter of tumors in the pEGFP-C/EBPα-K562 group were smaller than that of pEGFP-K562 group and K562 control group [(2.4±0.1) g vs (5.1±0.3) g and (5.7±0.4) g, both P ＜0.05; (11+2)mm vs (19+3) mm and (23+3) mm, both P ＜0.05]. More apoptosis cells were found in the pEGFP-C/EBPα-K562 group leukemic cells were found in the peripheral blood of leukemic models, and the proliferation of leukemic cells in the pEGFP-C/EBPo-K562 group were lower than that of other groups, accompany by the conspicuous cell differentiation. p53 was significantly elevated by RT-PCR, while down-regulated of c-myc.Conclusion Enhancer binding protein C/EBPα promote the apoptosis of cells and inhibit the proliferation of leukemia cells in leukemia mice, and further induce the cell differentiation. The inhibition of enhancer binding protein C/EBPα in the leukemia may have effect through the regulation of related genes.
