Leaves of Chrysanthemum morifolium were potential medicinal resource. The present study aims to estimate the main bioactive components: total flavonoids (TF), galuteolin (GA), quercitrin (QU), chlorogenic acid (CA) and 3 ,5-O-caffeoylquinic acid ( CQ), which were considered to be the main effective components, in leaves of C. morfolium cultivars in China. The TF content was estimated hy UV-VIS spectrophotometry, while GA, QU, CA, and CQ were quantitatively determined by HPLC. The highest TF content (7. 13% w/w) was found in cultivar Wan Cong (Shexian county). Cultivar Da Bo ( Bozhou county) had the highest GA content (33. 45 mg - g-1); Cultivar Hong Xin (Sheyang county) contained the highest QU content (29.25 mg · g(-1)); Cultivar Chang Ban (Sheyang county) had the highest CA content (13.14 mg ·(-1)). The maximum CQ content (7.35 mg · g(-1)) was observed in culti- r Da Yang ( Tongxiang county). Different cultivars of C. morfolium had significant difference in components, but the leaf and capitulum of C. morifolium. were found to possess similar chemical compositions. The high content of bioactive components in several cultivars suggested the potential utilization of C. morifolium leaves.

Objective To observe the apoptosis of human large cell lung cancer NCI-H661 cells induced by crotoxin,and to explore its mechanism. Methods The growth suppression of crotoxin on the NCI-H661 cells was detected by CCK-8 colorimetry,and the formation of NCI-H661 cells was observed by the plat colony experiment. This experiment included 4 groups:negative control group,crotoxin group(60 μg/ ml cro-toxin acted for 24 h),crotoxin + SB203580 group(pretreated cells using 5 μmol/ L SB203580 for 1 h,then 60 μg/ ml crotoxin acted for 24 h),SB203580 group(pretreated cells using 5 μmol/ L SB203580 for 1 h,then cultivated cells using complete culture solution). They were detected that the cell cycle and apoptosis rate of NCI-H661 cells treated with crotoxin by the flow cytometry. Additionally,they were tested that the change of the cell cycle and apoptosis rate after the NCI-H661 cells were treated with crotoxin and the activity of p38MAPK was inhibited by SB203580. Results When the concentration of crotoxin was greater than or equal to 30 μg/ ml,the inhibitory effect of crotoxin on the activity of NCI-H661 cells and colony formation,and inhibi-tion rate rose with increasing function of time and drug concentration. Flow cytometry showed that the apoptosis rate of crotoxin group and crotoxin + SB203580 group were(16. 70 ± 1. 38)% and(2. 15 ± 0. 54)% ,com-pared to the control group(1. 47 ± 0. 29)% ,and the former difference was statistically significant and the latter was not statistically significant(t = - 18. 763,P = 0. 000;t = - 1. 935,P = 0. 125). The G1 period cells of crotoxin group and crotoxin + SB203580 group were(57. 25 ± 1. 09)% and(48. 04 ± 1. 03)% ,compared to the control group(47. 46 ± 0. 69)% ,and the former difference was statistically significant and the latter was not statistically significant(t = - 13. 124,P = 0. 000;t = - 0. 809,P = 0. 464). Conclusion Crotoxin can promote the apoptosis of human large cell lung cancer NCI-H661 cells,and this effect may be related to the excitation of p38MAPK signal pathway.

The combination of Glycyrrhizae Radix et Rhizoma and Aconiti Lateralis Radix Preparata can increase efficacy and decrease toxicity. This study started from the phenomena of protein self-assembly in the mixed decoction of Glycyrrhizae Radix et Rhizoma with Aconiti Lateralis Radix Preparata. The attenuated mechanism was explored between the combination of Glycyrrhizae Radix et Rhizoma and Aconiti Lateralis Radix Preparata by using the protein of Glycyrrhizae Radix et Rhizoma and aconitine which was the major toxic component of Aconiti Lateralis Radix Preparata. Glycyrrhizae Radix et Rhizoma protein with aconitine could form stable particles which particle mean diameter was (206.2 ± 2.02) nm and (238.20 ± 1.23) nm at pH 5.0 in normal temperature. Through the mouse acute toxicity experiment found that injection of aconitine monomer all mice were killed, and injection of Glycyrrhizae Radix et Rhizoma protein-aconitine particles with the same content of aconitine all mice survived. Survey the stability of Glycyrrhizae Radix et Rhizoma protein-aconitine shows that the colloid particles is stable at room temperature, and it has the possibility to candidate drug carrier. Glycyrrhizae Radix et Rhizoma protein can reduce the toxicity of aconitine through self-assembly.

10.Expression of Maf-b mRNA in de novo leukemia patients and its clinical significance.
Journal of Experimental Hematology 2010;18(5):1147-1150
This study was aimed to quantitatively detect the level of maf-b mRNA in leukemia patients and evaluate its clinical significance. Real-time fluorescence quantitative PCR was used to detect the relative expression level of maf-b mRNA. The expression change of maf-b mRNA in various types of leukemia was analyzed. Then, the relationship of maf-b mRNA expression with laboratory index and the response to chemotherapy was analyzed. The results showed that maf-b mRNA expression level in acute myeloid leukemia (AML) patients was lower than that in normal group (p<0.01) and positively correlated with white blood cell count (p<0.01) and the expression of CD34 (p<0.01). There was no correlation between maf-b mRNA expression level and chemotherapy response in AML patients except for acute promyelocytic leukemia (APL). Maf-b mRNA expression levels in acute lymphoid leukemia (ALL) and chronic myeloid leukemia (CML) patients were also lower than that in normal group (p<0.01). It is concluded that there is low expression of maf-b gene in AML patients. Abnormal expression of maf-b correlates with abnormal proliferation of AML cells, which may be a new prognostic factor for AML.
