Acute leukemia is the most common malignant tumor in children in our country.Its pathogenesis includes transformation of proto oncogene,tumor suppressor gene distortion,inhibition of apoptosis etc..Under the action of carcinogenic factors,chromosome mutation,deletion,rearrangement or gene amplification can lead to the structural variation of proto oncogenes and tumor suppressor genes,resulting in a new fusion gene.Some of these genes are tran-scription factors regulating cell proliferation,differentiation,aging and death,when the gene is mutated,directly affect the downstream signaling pathways,leading to cell proliferation,apoptosis and enhanced (or)differentiation disorders, leading to leukemia.In recent years,with the development of gene sequencing technology,more and more leukemia prognostic genes have been displayed in public view and applied in clinical treatment and prognosis,relapse,etc..

Objective To optimize extraction process of flavonoids from Toosendan Fructus.Methods Three parameters that significantly affect the extraction rate of flavonoids, ratio of material to water, extraction time and ethanol concentration, were taken into consideration for extraction ratio of flavonoids from Toosendan Fructus. Based on the results of single-factor experiment, the extraction parameters of flavonoids from Toosendan Fructus were optimized by Box-Behnken of response surface methodology (RSM).Results The optimum extraction conditions were as follow: material to water ratio was 1:35; extraction time should be 3 h; ethanol concentration was 70%. The extraction ratio was up to 0.587 3% in the optimum extraction conditions.Conclusion The actual value is highly matching the theoretically value of RSM model. The results indicated that this method can rationally optimize extraction process of flavonoids from Toosendan Fructus.

Objective To explore the relationship between serum uric acid(SUA) levels and metabolic syndrome(MS) in middle-aged and elderly people,and to investigate the impacts of age and gender on the relationship between SUA and MS.Methods A cross-sectional study was carried out in general population aged over 35 years in rural area of Yiling District,Yichang City in 2007.All subjects were investigated by using the standardized questionnaire,physical and biochemical examinations.MS was defined according to the diagnostic criteria of the latest Chinese guidelines.All subjects were divided into different subgroups based on quartiles of SUA levels and age(35-44 years old,45-59 years old,over 60 years old).The relationship of MS with age and SUA levels were investigated.Results 9354 subjects consisted of 3883 males and 5471 females were included in this study.The percentage of subjects aged over 60 years was 21.1％ in men and 17.4％ in women.The prevalence of MS from the first quartile to the fourth quartile were 3.8％,5.5％,7.9％,15.2％ in males,and 3.1％,5.5％,7.9％,16.7％ in females,respectively.The SUA levels was positively correlated with MS in both sexes after adjusting for other confounding factors.By analyzing associated-subgroups based on age and SUA levels,logistic regression analysis showed that the risk of MS was significantly increased with aging and SUA levels in female subjects.The association between age and MS was significantly weaker in men than in women.Conclusions There is a positive correlation between SUA levels and MS.The associations of MS with age and SUA levels are more closely in women than in men.The risk of MS may be highest in middle-aged and elderly women with high level of SUA.

Objective:To evaluate the effect of paclitaxel on the mast cell-CCL2-macrophage axis in rats with pulmonary hypertension.Methods:Thirty SPF-grade healthy male Sprague-Dawley rats, aged 8-10 weeks, weighing 180-220 g, were divided into 3 groups ( n=10 each) using a random number table method: control group (group C), pulmonary hypertension group (group PH), and paclitaxel group (group PTX). The model of pulmonary hypertension was established by subcutaneous injection of monocrotaline 60 mg/kg in rats.At 25 days after establishing the models, paclitaxel 2 mg/kg was injected via the tail vein once every four days, for 4 times in total in group PTX.The equal volume of normal saline was injected in the remaining 2 groups.The mean pulmonary artery pressure (mPAP) was performed at 40 days after establishing the model.The heart was removed and dried, the right ventricle (RV) and left ventricle plus ventricular septum (LV+ S) was weighed, and the Fulton index [RV/(LV+ S)] was calculated.The inferior lobe of left lung was taken, the ratio of media wall thickness of pulmonary vessels was calculated by HE staining, the number of Tryptase + , CD68 + , CD163 + , and Ki67 + cells was recorded by immunohistochemistry, the mean value was calculated, the percentage of Ki67-positive cells in blood vessels was recorded, and the proportion of muscularized blood vessels was calculated.The content of CCL2 was measured by enzyme-linked immunosorbent assay, and the expression of cleaved caspase-3 and Cyclin D1 was detected by Western blot. Results:Compared with group C, the mPAP, Fulton index, ratio of media wall thickness, proportion of muscularized blood vessels, the number of Tryptase + , CD68 + and CD163 + cells and percentage of Ki67 + cells were significantly increased, and the expression of cleaved caspase-3 was down-regulated in PH and PTX groups ( P<0.05), the expression of Cyclin D1 was significantly up-regulated in group PH ( P<0.05), and no significant change was found in group PTX ( P>0.05). Compared with group PH, the mPAP, Fulton index, ratio of media wall thickness, percentage of muscularized blood vessels, the number of Tryptase + , CD68 + and CD163 + cells and percentage of Ki67 + cells were significantly decreased, the expression of CCL2 and Cyclin D1 was down-regulated, and the expression of cleaved caspase-3 was up-regulated in group PTX ( P<0.05). Conclusion:The mechanism by which paclitaxel alleviates pulmonary hypertension is related to inhibiting the mast cell-CCL2-macrophage axis in rats.
