Objective To evaluate the efficiency of low molecular weight heparin(LMWH, fraxiparine) given as a single predialysis bolus injection with reused dialyzers in comparison with standard heparin(SH) administered with a continuous infusion. Methods 30 hemodialysis patients were studied in a radomized crossover fashion. Dialyzers fibrer bundle volumes(FBV), predialysis hemocrit and 2 h clearance of urea, creatinine were observed in the first, the fourth dialysis. The plasma heparin activities(anti-Fxa levels) were measured by the chromogenic substrate assay in 0 h, 2 h, 4 h of dialysis. Results Significant increase (P<0.05) was seen in the number of dialyzer reuse in LMWH group compared with SH group; there was not significant decrease in dialysis FBV as well as 2 h clearance of urea, creatinine (P>0.05); in addition, the plasma heparin activity(anti-Fxa levels) were comparable in both groups after 2 h of dialysis, however, they were significantly higher after 4 h in the LMWH than those in the SH group (P<0.05). Conclusion LMWH as a single bolus dose can prevent decrease in dialyzer clearance. It is clinically worthy of further popularity.

Objective curcumin can suppress the proliferation , induce apoptosis and partial differentiation , and inhibit the migration of many kinds of tumor cells .The aim of this study was to investigate the expressions of mitogen-activated protein kinase (MAPKs) and matrix metalloproteinases (MMPs) when the proliferation of human multiple myeloma RPMI8226 cells was inhibited by curcumin in vitro, and to reveal the antitumor molecular mechanism of curcumin . Methods RPMI8226 cells were treated with various concentrations of curcumin for different periods of times .The inhibitory rate of curcumin on cell proliferation was detected by MTT assay , the cell cycle analyzed by flow cytometry , the protein levels of MAPKs measured by Western blot , and the activity of MMPs analyzed by Gelatin zymography . Results Curcumin inhibited the proliferation of RPMI 8226 cells in a time-and dose-dependent manner , and the cell cycle was arrested in the G 2/M phase ([12.72 ±0.68]%vs [4.79 ±0.15]%).The expressions of JNK and p-JNK showed a con-centration-dependent increase in the RPMI8226 cells treated with curcumin at 6.25, 12.50, and 25.00 μmol/L, respectively (P<0.01) , but the expressions of ERK 1/2 and P38 MAPK did not change significantly compared with the control group (P>0.05).In addition, the activities of MMP-2 and MMP-9 were decreased in a dose-depend-ent manner in the supernatant of RPMI8226 cells ( P <0.01). Conclusion A certain concentration of curcumin could not only acti-vate the JNK signalling pathway of the MAPKs family and induce the apoptosis of RPMI8226 cells, but also inhibit the activity of MMPs and influence the invasion and metastasis of RPMI 8226 cells.

Poly(ADP-ribose) polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. It can polymerize ADP-ribose units on its substrate proteins which are involved in the regulation of DNA repair. In this work, a novel series of para-substituted 1-benzyl-quinazoline-2, 4 (1H, 3H)-diones was designed and synthesized, and the inhibitory activities against PARP-1 of compounds 7a-7e, 8a-8f, 9a-9c and 10a-10c were evaluated. Of all the tested compounds, nine compounds displayed inhibitory activities with IC50 values ranging from 4.6 to 39.2 micromol x L(-1). In order to predict the binding modes of the potent molecules, molecular docking was performed using CDOCKER algorithm, and that will facilitate to further develop more potent PARP-1 inhibitors with a quinazolinedione scaffold.
