Objective In order to study the application of macroporous resins and so on to the purified active components of Euphorbia humifusa、Leaves of Flos Lonicerae、Chrysanthemum morifolium,adsorption and separation properties for 3 types of macroporous resins and polyamide were investigated.Methods The total flavone was used as the evaluating criteria,we selected suitable macroporous resins and studied optimum technological parameters of the adsorption and elution.Spectrophotometry was used for the determination of total flavone.Results The suitable macroporous resins which were used to the purified active components of traditional Chinese medicine were D101 and DA201 and DM301 for Euphorbia humifusa、DA201 for Leaves of Flos Lonicerae、D101 and DA201 and DM301 for Chrysanthemum morifolium,The concentration of the sample of Euphorbia humifusa for DA201 and D101 were 0.49～1.47 and 0.42～1.31 mg/ml.The concentration of the sample of Leaves of Flos Lonicerae for DA201 was 1.03～2.07 mg/ml.The concentration of the sample of Chrysanthemum morifolium for DA201 and D101 was 0.50～1.00 and 0.71～1.99 mg.ml.In the adsorption course,appeared leaking were 8 and 10、2、2 and 1 BV respectively.In the elution course,when the alcohol concentrations were 20%、30%、40% and 20%、30%、40%;10%、20%、30%;30%、40%、50% and 20%、30%、40%;respectively,the total flavone content in the elution solutions was higher.The influence of temperature to DA201 and D101 adsorpting total flavone for Euphorbia humifusa was not great.But the influence of temperature to DA201 and D101 adsorpting total flavone for Leaves of Flos Lonicerae and Chrysanthemum morifolium were certain degree.Conclusions It is obviously different to refine the total flavone active components of traditional Chinese medicine,while using 3 types of macroporous resins and polyamide.

The interventional treatment of lung cancer is tightly related with hemodynamic situation of artery.To study hemodynamics of the interventional treatment of lung cancer can significantly improve curative effect and decrease complications.Through simulation experiment,the ratio of drug injection around the entrance of bronchial artery is obtained and the definition of natural perfusion region is given.The evidence for interventional treatment of lung cancer and the principle avoiding high-level paraplegia in clinical interventional treatment of lung cancer are also presented.

Objective To observe the effects of the compatibility of Radix Astragali and Radix Angelicae Sinensis in different proportion on hemodynamic and balance of Th1/Th2 cells of Qi deficiency and blood stasis rat model. Methods Qi deficiency and blood stasis rats were caused by restricted diet, forced swimming and norepinephrine subcutaneous injecting, and treated by compatibility of Radix Astragali and Radix Angelicae Sinensis in different proportion of 5∶1, 3∶1, 1∶1 and 1∶2 for 21 days. The indexes of hemorheology were detected with hemorheological analyser, and the level of IFN-γand IL-4 in serum were tested by ELISA. Results Compared with model group, the compatibility of Radix Astragali and Radix Angelicae Sinensis in proportion of 1∶1, 3∶1 and 5∶1 groups reduced the low shear blood viscosity. The spleen index of model group decreased, and compatibility of Radix Astragali and Radix Angelicae Sinensis in 5∶1 proportion group increased spleen index. The level of IL-4 increased and IFN-γ decreased in the serum of model group, the compatibility of Radix Astragali and Radix Angelicae Sinensis in proportion of 3∶1 group increased the level of IFN-γ. Astragalus angelica 5∶1 group decreased the level of IL-4 and increased the level of IFN-γ. Conclusion The compatibility of Radix Astragali and Radix Angelicae Sinensis can improve hemorheology, adjust the balance of Th1/Th2 cells of Qi deficiency and blood stasis rats. The effects were better when Radix Astragali’s dosage greater than that of Radix Angelicae Sinensis, and the group of 5∶1 proportion was the best.

Objective To investigate the quality of life and its influencing factors in hver transplantation recipients in order to supply scientific reference for improving their life quality.Methods 33 patients with terminal liver diseases waiting for liver transplantation(the pre-operation group)and 102 patients 2 weeks after liver transplantation and outpatients for follow-up visits(the post-operation group)were conducted with SF-36,self-rating anxiety scale,self-rating depression scale,and social support questionnaire.Results Except for the scores of physiological function,emotional role,social function in SF-36.differences of scores of other factors were evident between the preand post-operation groups.Life quality of patients over 1 year after operation was better than those within 1 year. The influencing factors of QOL were subjective support and anxiety.Conclusions After liver transplantation,the patients' QOL evidently improves.Life quality of patients over 1 year after operation was better than those within 1 year.Patients' QOL is positively related to subjective support,negatively related to anxiety.

A poly( GMA-EGDMA) coated SPME fiber was prepared using an in-situ polymerization by direct bonding to the surface of a polydopamine-modified stainless steel wire. Then the fiber was modified by sulfuric acid. A novel solid phase microextraction coating coupled to high performance liquid chromatography ( HPLC) method based on the as-prepared fiber was developed for the determination of four pharmaceuticals and personal care products ( PPCPs) in water samples. The influences of extraction parameters, including pH, extraction time, extraction temperature and salt addition were investigated. 3 mL water sample was extracted by the as-prepared fiber for 60 min at 30 ℃, and then desorbed with mobile phase for 30 min, respectively. Desorption solution was analyzed by HPLC-DAD ( diode array detection ) . The results indicated that the extraction yield of the fiber was good for four PPCPs. The linear correlation coefficients were>0. 997 with the linear range of 2-200 μg/L. The limits of detection (S/N=3) were 0. 5-5 μg/L with RSD (n=5) of 4. 1%-11. 9%. The recoveries of four PPCPs at spiked level of 20, 50, 100 μg/L were within the range of 70. 6%-105. 5%. The results showed that this method was easy, green, accurate and precise, and could be used to assay the four PPCPs in real water samples.
