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.

Objective To observe the effects of Wendan decoction (WD) on depression-like behavior in a rat model of Parkinson's disease (PD) and explore the related mechanism.Methods Rodent model of PD was established by unilaterally lesioning medial forebrain bundle with 6-hydrodopamine.After intragastric administration with WD,the rats's behavior changes were detected by the open field test,sucrose preference test and forced swimming test;the contents of monoamine neurotransmitters in the rat brain were assessed by high-performance liquid chromatography with electrochemical detection.Results Compared with those of sham-operated rats,the horizontal and vertical activities of the PD model rats decreased significantly,and sucrose consumption decreased significantly,but immobility time during forced swimming was significantly prolonged.The contents of dopamine (DA),5-hydroxytryptamine (5-HT) and noradrenaline (NA) in the medial prefrontal cortex (mPFC) and DA in the striatum decreased significantly.After administration of WD for 2 weeks,the immobility time of the PD model rats was significantly decreased,sucrose consumption increased significantly;DA,5-HT and NA levels in the mPFC increased significantly.Conclusion WD improves the depression-like behavior in PD model rats,and the mechanisms may involve the regulation of monoamine neurotransmitters in mPFC.

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.

Objective: To study the serum interleukin-37 (IL-37) level changes in patients with acute coronary syndrome (ACS) and to explore the relationship between IL-37 and coronary atherosclerotic plaque.
Methods: Our research included 3 groups. ACS group, n=60, SAP (stable angina pectoris) group, n=30 and Control group, the subjects with normal coronary artery, n=15. The peripheral serum levels of IL-37 were examined by ELISA and the differences were compared among different groups.
Results: ① The serum levels of IL-37 at admission were as ACS group < SAP group < Control group, P<0.05.②Intervention could transitionally decrease IL-37 level in SAP group. With 4 weeks treatment, IL-37 levels were signiifcantly increased in both ACS group and SAP group than admission time, while they were still lower than Control group, P<0.05.③The serum level of IL-37 at admission was negatively related to IL-18 (r=-0.79, P<0.05), the ratio of IL-18/IL-37 were as ACS group>SAP group>Control group, P<0.05.④In ACS group, IL-37 level was negatively related to GRACE score (r=-0.71, P<0.05), the ratio of IL-18/IL-37 was positively related to GRACE score (r=0.73, P<0.05).⑤The diagnosis of ACS could be basically excluded if the patients with IL-37>77ug/L.
Conclusion: The serum IL-37 might be involved in the inlfammatory process in ACS patients, it could be expected as an index for ACS monitor and evaluation in clinical practice.
