Objective To optimize the purification technology of total flavonoids from the Tripterospermi Chinensis Herba by macroporous resin. Methods The purification abilities of six kinds of macroporous adsorption resins for total flavonoids from Tripterospermi Chinensis Herba were studied with the adsorption and desorption rates as the index by static adsorption and desorption experiments. The column liquid concentration, adsorption rate, and the loaded amount were studied by using dynamic adsorption experiments. The optimal desorption technology was examined by orthogonal experiment. Results AB-8 macroporous resin was found to have good adsorption and desorption effects. The optimal purification conditions were as follows:the column liquid concentration was 5.285 mg/mL, adsorption rate was 2 BV/h;the loaded amount was 17.62 mg/mL. The sample was eluted by 10%ethanol with 4 BV and 50%ethanol of 5 BV at a flow rate of 4 BV/h. The purity of total flavonoids increased to 61.95% after the purification, and the yield was 87.28%. Conclusion This optimized process was stable, feasible and suitable for separation and purification of total flavonoids from Tripterospermi Chinensis Herba.

Objective To study the adsorption technology of piceid on macroporous resin. Methods The extraction condition of piceid, the types of macroporous resin, the concentration of the sample of Rhizoma Polygoni cuspidati extract, the flow velocity of samples during adsorption were investigated and the leak curve was drawed to ascertain the optimal sample quantity. Results Resin D101 gave a better adsorption performance in the following technological conditions:the concentration of the sample of Rhizoma Polygoni cuspidati extract was 0.7774 mg/mL, the flow velocity of sample during adsorption 3BV/h, the optimal adsorption capacity of the resin was 10.88 mg/mL. Conclusion The procedure was simple, feasible and can be applied to industrial production.

Objective To evaluate the efficacy of surgical excision combined with iodine-125 implants intmcavitary radiotherapy for neumglioma Method After excision,27 patients with nenroglioma were implanted with the iodine-125 into the tumor bed or the residual tumor tissues.Results Of all cases,there were no operative mortality and no serious complication.The survival time of 25 cases exceeded 6 months and 1 glioblastoma recurrence,22 cases exceeded 12 months,3 glioblastoma and 1 astrocytoma Ⅲgrade recurrence.There were 19 cases exceeding 24 months,15 cases no recurrence,3 cases died for cere bral hernia because of giving.up further tremment,1 case surviving.Conclusions Surgical excision Combined with iodine-125 implants intracavitary radiotherapy can improve partial control rate,prolonged the survival time of patients with neuroglioma,and complications is rare.It is an efficient therapy for neu roglioma
