Myelodysplastic syndromes (MDS) are a heterogenous group of hematologic malignancies characterized by clonal expansion of BM myeloid cells with impaired differentiation. Of particular interest mutations is the recent recognition that genes involved in the regulation of histone function (EZH2, ASXL1,and UTX) and DNA methylation (DNMT3A,IDH 1/IDH2,TET2) are recurrently mutated in MDS,providing an important link between genetic and epigenetic alterations in this disease. Ongoing analysis of the seminal AZA-001study has taught many important lessons in the use of DNA methyltransferase (DNMT) inhibitors.Improved survival in patients with high-risk MDS treated with azacitidine extends to patients with any International Working Group-defined hematologic response.New information on the impact of DNMT inhibitors on the immune system and on stem cells will likely lead to novel uses of these drugs in MDS and other hematologic and nonhematologic malignancies. The immunomodulating drug thalidomide and its derivative lenalidomide have been used in the treatment of MDS,principally in lower-risk MDS.

Objective To compare the difference among DNA damages in physics processes caused by protons with different energies around Bragg peak.Methods By constructing the nucleus and DNA model using Geant4 and simulating the transportation processes of protons with different energies around Bragg peak in nucleus model based on Geant4-DNA,the information of interaction points were recorded.16％ of them were picked randomly to use as the points at which protons interact with DNA.After finding out the points which broke the DNA and writing their information to new files,these new files were treated with density-based spatial clustering of applications with noise (DBSCAN),so as to analyze and calculate the difference of DNA damages caused by protons with different energies.Results With the protons with energies from 20.0 to 0.6 MeV,the numbers of damage points and damage clusters increased from 49.86 to 549.88 and from 2.92 to 82.46,respectively;the numbers of clusters with different sizes had a remarkable increase,and the number of clusters with size not less than 5 increased by 400 times.The average cluster size increased slightly.Simple single strand breaks (SSSBs),complex single strand breaks (CSSBs),simple double strand breaks (SDSBs) and complex double strand breaks (CDSBs) of DNA increased by about 8,26,24 and 64 times,respectively.The proportion of single strand breaks (SSBs) decreased from 96.69％ to 89.37％,and the double strand breaks (DSBs) increased from 3.31％ to 10.63％.Conclusions The lower proton energy would result in the more complex damage to DNA and the harder repair of DNA damage.

OBJECTIVE: To study the effect of MDR1 (P-gp) and ABCG2 on the drug resistance in Hep 2 cells. METHOD: Flow cytometry was used to detect the variations of the antitumor drugs accumulation and discharging, and activity variations when MDR1 and ABCG2 inhibitors were used in Hep-2. RESULT: The accumulation and discharging of mitoxantrone was significantly higher than the control group when ABCG2 inhibitor FTC was used in Hep-2 (P<0. 05). In contrast, P-gp did not appear similar case; To the mitoxantrone and cisplatin, there was no statistical correlation about activity of Hep-2 between P-gp or ABCG2 antagonist and the control; To the doxorubicin, combining FTC and P-gp, the activity of Hep-2 was higher than the control and difference was significant (P<. 05), In contrast, FTC and P-gp did not appear similar case when used alone; To the 5-FU, when PGP used, the activity of Hep-2 was higher than that in the control and difference was significant (P<0. 05), In con- trast, FTC and FTC+P-gp did not appear similar case; To the paclitaxel, when P-gp or FTC+P-gp used, the activity of Hep-2 was higher than that in the control and difference was significant(P<0. 05). CONCLUSION ABCG2 may lead to drug resistance mainly by changing the ability of cell in accumulating and discharging chemotherapy drugs. P-gp has other way. P-gp and ABCG2 play different roles in different drug resistance.

This study is to screen 23 blank O/W type microemulsion (ME) samples, that is 15 samples from our laboratory, and 8 samples from literature; compare the conductivity-water content curve (CWCC) method and visual method in determining the critical water content during O/W type MEs' formation, to analyze the deficiency and the feasibility of visual method and to exploxe scientific meanings of CWCC method in judging the critical water content of O/W type MEs during formation. The results show that there is a significant difference between the theoretical feasible CWCC method and visual method in determining the critical water content (P<0.001), and the results judged by conductivity is higher than that by eye-based water content. Therefore, this article firmly confirmed the shortcomings of visual method and suggested that the eye-base "critical water content" may falls into continuous ME stage during O/W MEs' formation. Further more, the CWCC method has theoretical feasibility and scientific meanings in determining the critical water content of O/W type MEs during formation.
