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.

Extracellular signal-regulated kinases 1 and 2 (ERK1/2) pathway, which was the first cell signal transduction pathway to be discovered, consisted of Ras, Raf, MEK1/2 and ERK1/2. After the activation of ERK1/2 pathway, extracellular signals can be transmitted from the cell membrane to the nucleus. It was involved in many physiological and pathological functions of cells, such as growth, proliferation, differentiation, apoptosis and etc. It was also related to the onset of many diseases, which included multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE). The activation of ERK1/2 pathway can induce the activation of astrocyte, MG, T cell and macrophage, which released a variety of inflammatory cytokines. It caused myelin damage which induced MS/EAE onset. A number of studies indicated that inhibiting ERK1/2 pathway can reduce the releasing of inflammatory cytokines and myelin damage for MS/EAE alleviation. It provided an important target for the development of MS treatment medication.

Objective:To evaluate curative impact of booster immunization with paternal lymphocytes on recurrent spontaneous abortors(RSA)with less reaction of primary patermal lymphocyte immunization.Methods:RSA patients with insufficient materno-fetal immuno-recognition were selected by flow cytometry of blocking antibody analysis and immunized with either induced paternal lymphocytes pretreated by IFN-? in vitro to those of anti-CD3-BE and anti-CD4-BE Ab lower than 0% or direct intradermal vaccination with their paternal lymphocytes without IFN-? pretreatment to those of anti-CD3-BE Ab beyond 0%.Reassessment of blocking antibodies was performed at the end of the second immnunization course.Results:Levels of blocking antibodies were significantly raised after the secondary booster immunization in RSA with insufficient materno-fetal immnuno-recognition whose blocking antibodies continuously decreased after being treated by the primary paternal lymphocyte immunization.No improvement of parameters was observed except the blocking effect in patients receiving secondary direct intradermal vaccination treatment.Conclusion:It is necessary for the RSA with insufficient materno-fetal immuno-recognition to experience secondary booster immunization preferably with paternal lymphocytes pretreated by IFN-? in vitro.

Objective To study the inhibit efficiency of lake sediment phosphorus release by adding chemical reagents and to provide the technical basis for the comprehensive management of city lake.Methods In May 20,2008,Mochou Lake upper sediment and water samples were collected.The phosphorus forms of sediments,total phosphorus(TP),NaOH-P,HCl-P,inorganic phosphorus(IP),organic phosphorus(OP) were analyzed and the pH value and content of TP in water samples were determined.Each water(250 ml)-sediment(10 g) system was respectively added by 0-1 000.0 mg/L of Ca(OH)2,2.0-10.0 mg/L of A12(S04)3 and 0-25.0 mg/L of FeCl3.The pH value and content of TP in water were determined,then the control rate of TP release were calculated.Results The pH values were between 7.6-8.0,TP content was 2.0 mg/L in water of Mochou Lake.The contents of TP,HCl-P,NaOH-P,IP,OP were 2 187.06,1 383.89,526.48,1 910.37 and 276.69 mg/kg respectively.With the increase of Ca(OH)2 concentration,pH value of water increased rapidly,content of TP showed a decreasing trend,control rate of TP release was increased.With the increase of A12(SO4)3 or FeCl3 concentration,pH value of water declined slightly,content of TP showed a decreasing trend,control rate of TP release was increased.Conclusion Ca(OH)2,A12(SO4)3,FeCl3 can significantly inhibit the phosphorus release of sediments in Mochou Lake.

Objective To study the correlation between dose-volummetrics and changes of pulmona- ry function tests(PFTs), and to study the ability of standard dose-volummetrics to predict these changes after radiotherapy. Methods Pulmonary function was measured in 39 patients with inoperable lung cancer one week before and 2-4 months after radiotherapy. The pulmonary function parameters were the forced vital ca- pacity(FVC), forced expiratory volume in ls (FEV 1.0) and diffusion capacity of carbon monoxide(DL- CO). Dose-volumrnetrics were V_(10), V_(15), V_(20), V_(25), V_(30), V_(35), V_(40), CTV_(100), CTV_(95), CTV_(90), CTV_(80), lung D_(mean), V_(eff) and NTCP. Pearson and line regression analysis was performed to determine whether the correlation exis- ted between the metrics and the changes of PFTs. Results No correlation was found between the dose- volummetrics and the changes in PFTs. Excluding patients(n=15) with pretreatment atelectasis, signifi- cant correlation was found between the dose-volummetrics (V_(20), V_(25), V_(30), V_(35), V_(40), GTV, V_(eff) and D_(mean)) and the PFTs changes(r=0.469-0.695, P≤0.05). Therefore, the re-expansion may have jesperdized the proper data to the present record. Multivariate analysis showed that V_(30) was the risk factor to affect the chan- ges of FEV 1.0 and DLCO(P=0.046、0.041). The pulmonary function of patients with V_(30)≥18% was worse than patients with V_(30)
