Pathogenesis of acute promyelocytic leukemia is one of the best understood disease among human hematological malignancies. Becasue of retinoic acid (RA) and arsenic trioxide which directly target the oncogenic promyelocytic leukemia-retinoic receptor A (PML-RARα) fusion protein, this disease became the first model for oncogene-targeted therapies.And other new therapy methods also gain great concern. The complexity of recent views of acute promyelocytic leukemia pathogenesis, as well as latest progress in clinical treatment were summarized and discussed in this review.

In order to solve the adhesion and the softening problems of traditional Chinese medicine extract during spray drying, a new method of adding dehumidified air into spray drying process was proposed, and the storage stability conditions of extract powder could be predicted. Kouyanqing extract was taken as model drug to investigate on the wet air (RH = 70%) and dry air conditions of spray drying. Under the dry air condition, the influence of the spray drying result with different air compression ratio and the spray-dried powder properties (extract powder recovery rate, adhesion percentage, water content, angle of repose, compression ratio, particle size and distribution) with 100, 110, 120, 130, 140 °C inlet temperature were studied. The hygroscopic investigation and Tg value with different moisture content of ideal powder were determined. The water activity-equilibrium moisture content (aw-EMC) and the equilibrium moisture content-Tg (EMC-Tg) relationships were fitted by GAB equation and Gordon-Taylor model respectively, and the state diagram of kouyanqing powder was obtained to guide the rational storage conditions. The study found that in the condition of dry air, the extract powder water content decreased with the increase of air compression ratio and the spray drying effect with air compression ratio of 100% was the best performance; in the condition of wet air, the extract powder with high water content and low yield, and the value were 4.26% and 16.73 °C, while, in the dry air condition the values were 2.43% and 24.86 °C with the same other instru- ment parameters. From the analysis of kouyanqing powder state diagram, in order to keep the stability, the critical water content of 3.42% and the critical water content of 0.188. As the water decreased Tg value of extract powder is the major problem of causing adhesion and softening during spray drying, it is meaningful to aid dehumidified air during the process.

There are 250 species of Zanthoxylum (Rutaceae) in the world. This genus distributed in tropical and subtropical regions. Alkaloids are the major and representative ingredients in these plants including quinolines, isoquinolines, and amide alkaloids, with such biological activities as anti-tumor, anti-inflammatory, analgesic, anti-virus, anti-platelet aggregation, anti-bacteria and anti- oxidant. These species have been used for a long time to treat toothache, urinary and venereal diseases, lumbago and rheumatism. This review summarizes the chemical constituents and pharmacological activities from the Z. sppplants, in an effort to the systematic research and application of the alkaloids of this genus.

Aim To observe the physical coupling between transient receptor potential channel vanilloid type 4 (TRPV4 ) and cPLA2 in endothelial cells. Methods We investigated the physical association of TRPV4-cPLA2 coupling by immunofluorescence reso-nance energy transfer (immuno-FRET)to assess the spatial proximity between TRPV4 and cPLA2 in human microvascular endothelial cells (HMEC),primary cul-tured endothelial cells and in thoracic aortas rings from high salt-induced hypertension mice.Results At the cellular level,with high salt treatment,the physical in-teraction of TRPV4 and cPLA2 was significantly en-hanced in primary vascular endothelial cells and HMEC.Furthermore, in thoracic aortas rings from high salt-induced hypertension mice,we found an in-creases interaction between TRPV4 and cPLA2 in en-dothelial cells from arterial segments .Conclusion High-salt treatment increases the endothelial TRPV4-cPLA2 coupling,indicating that this coupling may pro-vide a new target for vascular endothelial dysfunction.

Sixty-six volunteers,including 24 subjects with normal glucose tolerance(NGT),18 patients with impaired glucose regulation (IGR),and 24 patients with type 2 diabetes mellitus ( T2DM ),underwent a test of continuous glucose monitoring.The data of continuous glucose monitoring were embedded into two-dimension Euclid space by Takens' embedding theory.Glycemic phase diagram was drawn by MATLAB.The area and center distance of glycemic phase diagram were calculated by computer.The distinction of glycemic variability and average glycemic level among different glucose regulation populations were analyzed.The results showed that there existed significant differences in body mass index,systolic blood pressure,diastolic blood pressure,low density lipoprotein-cholesterol,high density lipoprotein-cholesterol,triglyceride,total cholesterol,creatinine,and alanine aminotransferase among three groups( all P<0.05 ).The levels of HbAIC,fasting plasma glucose( FPG ),postprandial 2 h plasma glucse (2hPG),area and center distance of glycemic phase diagram in T2DM group were higher than those in NGT and IGR groups( P<0.01 ),and the levels of FPG,2hPG,area and center distance of glycemic phase diagram in IGR group were higher than those in NGT group( P<0.01 ).The levels of FPG and 2hPG were correlated with area and center distance of glycemic phase diagram ( all P<0.01 ).These results suggest that measuring the area and center distance of glycemic phase diagram is a good method to assess glycemic variability and average glycemic level during continuous glucose monitoring.
