Aim To Study the inhibition mechanism of edelfosine on cytokinesis in Schizosaccharomyces pombe. Methods To observe the inhibition of cytokinesis and growth, the experiments of inhibition of cyto-kinesis and parallel growth were carried out. To explore the inhibition mechanism of edelfosine, the experiment of retransfection of yeast genes was carried out. Results Edelfosine inhibited the cytokinesis of S.pombe in low dosage and cell growth in high dosage. The mid2△、spm1△ and pmp1△ strains were resistant to edelfosine in high dosage. However, these strains retrieved the sensitive to edelfosine in high dosage by retransfected the relevant genes, respectively. A reciprocal action, which was the Mid2p induced the phosphorylated Spm1, while the Pmp1 dephosphorylated Spm1, existed among the Spm1、Mid2 and Pmp1 in S.pombe treated with edelfosine. Conclusion The inhibition of edelfosine on cytokinesis and cell growth due to the effect of Spm1、Mid2 and Pmp1.

Objective To explore the role of the change of the CD11b expression in hyperleukocytosis and acute promyelocytic leukemia(APL) differentiation syndrome, we observed the effects of all-trans retinoie acid(ATRA) and trioxide arsenic(ATO) alone or the combination together with daunorubicin (DNR) on CD11b expression of human APL cell line NB4 cells. Methods By using the mono-antibody of CD11b FITC-conjugated, we monitored the level of CD11b expression of NB4 cells by flow cytometry. Results With the length of the 1 μmol/L ATRA exposure,the CD11b expression was increased. Exposed to ATRA for 24 h, 48 h, 72 h and 168 h;the CD11b expression of NB4 cell was (33.34±3.15)%, (55.59±5.13)%, (86.08±5.12)% and (90.69±2.69)%, respectively which were higher than control group and the difference was statistically significant (P<0.01). With the length of the 1 μmol/L ATO exposure, the CD11b expression showed no significant difference with control group(P>0.05), but was significantly lower than that in ATRA exposure(P<0.01). Exposed to 1 μmol/L ATRA combined with 1 μmol/L ATO for 72 h and 168 h, the CD11b expression were (18.81±1.40)% and (25.61±4.54)%, which were significantly higher than that in control group (P<0.05, P<0.01), but significantly lower than ATRA exposure (P<0.01). With the exposure to 1 μmol/L ATRA combined with 1 μmol/L ATO and 1 μmol/L DNR, the CD11b expression was also significantly lower than ATRA exposure (P<0.01) and showed no difference with control group (P>0.05). Conclusion By avoiding the increase of CD11b expression of promyelocytic leukemia cells, ATRA combined with ATO or two drugs together with DNR could play a role in eliminating incidence of hyperleukocytosis and retinoic acid syndrome.

Objective To discuss the relationship between matrix metalloproteinases 9 (MMP-9) and the pathogenesis of preeclampsia , birth weight and placental weight , through detecting the expression of MMPS-9 in the placenta of the patients with preeclampsia. Methods The levels of MMP-9 in the placenta were detected by immunohistochemical SP method in 60 patients with preeclampsia and 30 pregnancy women. Results (1) The optical density value of MMP-9 in preeclampsia group was lower than the control group , the optical density value of MMP-9 in SPE group was lower than the MPE group (P < 0.05). (2) The placenta weight and birth weight in preeclampsia group were lower than the control group , the placenta weight and birth weight in SPE group was lower than the MPE group (P < 0.05). (3) The expression level of MMP-9 were positively correlated with placental weight and birth weight (P < 0.05) in the control group. (4) The average optical density value of MMP-9 in neonatus with weight < 2 500 g was lower than neonatus with weight≥2 500 g (P < 0.05). Conclusion The MMP-9 in the placenta of patients with preeclampsia was down-regulated , and its expression was abate when the illness grew worse. The MMP-9 may be involved in the pathogenesis of preeclampsia , and it is associated with fetal growth restriction.

OBJECTIVE: To explore the effects of Yanggan Lidan Granule (YGLDG), a compound traditional Chinese herbal medicine for nourishing liver and improving choleresis, on the rate of gallstone formation and content of plasma cholecystokinin in guinea pigs with induced cholesterol gallstones. METHODS: Eighty guinea pigs were randomly divided into 4 groups, which were normal control group, untreated group, YGLDG-treated group and ursodeoxycholic acid (UDCA)-treated group (n=20). Except the normal control group, gallstones were induced by high-cholesterol diet in the guinea pigs. YGLDG (1.81 g/kg daily) and UDCA (30.12 mg/kg daily) were given orally to guinea pigs in the corresponding group respectively for seven weeks; however, the guinea pigs of normal control group and untreated group were administered with normal saline. The physical signs of the guinea pigs and the rates of gallstone formation were examined, and the content of cholecystokinin (CCK) in the plasma was detected by radio-immunoassay. RESULTS: YGLDG could obviously improve the ethological signs of the guinea pigs. Gallstone formation rate of the untreated group (82.35%) was significantly increased as compared with that of the normal control group (5.26%) (P<0.01), while the gallstone formation rates of the YGLDG-treated group (27.28%) and UDCA-treated group (38.89%) were lower than that of the untreated group (P<0.05). The content of CCK in plasma of the untreated group was significantly lower than that of the normal control group (P<0.01), while CCK content of the YGLDG-treated group and UDCA-treated group was lower than that of the normal control group, but both of them were significantly higher than that of the untreated group (P<0.01). The difference of CCK levels between YGLDG-treated group and UDCA-treated group had no statistical significance (P>0.05). CONCLUSION: YGLDG can significantly decrease the rate of gallstone formation in guinea pigs. It may be related to elevating the content of CCK in the plasma.
