In order to establish the quality classification criteria of Paeonia suffruticosa seeds, thirty-one batches of P. suffruticosa seeds from different provenances were selected. The seed rooting rate, seed germination rate, seed purity, seed viability, 1,000-seed weight and moisture content were determined and analyzed through SPSS 20.0 software. Seed rooting rate, seed germination rate and seed purity were selected as the main index for classification, while 1,000-seed weight, seed viability and moisture content could be used as important references. The seed quality grading of P. suffruticosa was set as three grades. The seed quality of each grade should meet following requirements: For the first grade seeds, seed rooting rate ≥ 80%, seed germination rate ≥ 80%, seed purity ≥ 90%, seed viability ≥ 80%, 1,000-seed weight ≥ 250 g, moisture content, ≤ 10. For the second grade seeds, seed rooting rate ≥ 50%, seed germination rate ≥ 60%, seed purity ≥ 70%, seed viability ≥ 75%, 1,000-seed weight ≥ 225 g, moisture content ≤ 10. For the third grade seeds, seed rooting rate ≥ 20%, seed germination rate ≥ 45%, seed purity ≥ 60%, seed viability ≥ 45%, 1,000-seed weight ≥ 205 g, moisture content ≤ 10. The quality classification criteria of P. suffruticosa seeds have been initially established.

ObjectiveTo evaluate the clinical efficacy and toxicity of reduced dose idarubicin and cytarabine,semustine(IAS) regimen as induction therapy in patients with acute myeloid leukemia.MethodsA total of fifty-eight newly acute myeloid leukemia(AML) patients were randomly divided into 2 groups,including 30 cases with IAS regimen,28 cases with DA regimen The IAS regimen was treated with reduced dose idarubicin (8 ～ 10 mg/m2,days 1 to 3) and cytarabine( 100 ～ 150 mg/m2,days 1 to 7),semustine(200mg,d0).The DA regimen was treated with daunorubicin(40 ～60 mg/m2,days 1 to 3) and cytarabine ( 100 ～ 150 mg/m2,days 1 to 7).The responses ( CR and overall response rate ) were compared between the 2 groups.Results Complete remission(CR) rate in IAS and DA groups were 24 of 30( 80.0％ ) and 16 of 28 (57.1％ ) respectively,while the overall response rate were 26 of 30 ( 86.7％ ) and 18 of 28 ( 64.3％ ) respectively.There was significant difference in CR rate and overall response rate between IAS group and DA group( P ＜ 0.05 ).Myelosuppression and infections due to neutropenia were the most frequent adverse effects,severe nonhematologic toxicity was not observed.The incidence rates of toxicities in the 2 groups were not significantly different ( P ＞ 0.05 ).Conclusion The effect of reduced dose idarubicin and cytarabine,semustine regimen in the treatment for acute myeloid leukemia is superior to that of DA regimen,and the toxicities are tolerable.IAS regimen can be as the optional induction therapy in newly patients with acute myeloid leukemia.

Molecularly imprinted polymers (MIPs) with high selectivity to tilmicosin (TIM) were prepared using tylosin(TYL) as dummy template, methacrylic acid(MAA) as monomer, ethylene glycol dimethacrylate (EGDMA) as cross-linker.The effects of 4 porogens including dimethyl formamide, methanol, acetone, and chloroform on the recognition capability of MIPs were investigated.Orthogonal test was used to optimize the preparation of MIPs, and the optimal composition was as follows; 1.0 mmol TYL, 8.0 mmol MAA, 20.0 mmol EGDMA, 6.0 mL chloroform, 20.0 mg azobisisobutyronitrile.The solid phase extraction condi tions and characteristics of MIPs as adsorptive material for the selective extraction and enrichment of TIM were also studied.The recovery of TIM was above 90% when the following procedure was applied to MIPs cartridge: conditioning with methanol and water(pH 9.0), loading with acetonitrile, cleaning with methanol and chloroform respectively, and eluting with 3 mL methanol-ammonia(95:5, V/V).The recovery of TIM on non-imprinted polymers cartridge was only 32%.

Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

In order to optimize the testing methods for Paeonia suffruticosa seed quality, and provide basis for establishing seed testing rules and seed quality standard of P. suffruticosa. The seed quality of P. suffruticosa from different producing areas was measured based on the related seed testing regulations. The seed testing methods for quality items of P. suffruticosa was established preliminarily. The samples weight of P. suffruticosa was at least 7 000 g for purity analysis and was at least 700 g for test. The phenotypic observation and size measurement were used for authenticity testing. The 1 000-seed weight was determined by 100-seed method, and the water content was carried out by low temperature drying method (10 hours). After soaking in distilled water for 24 h, the seeds was treated with different temperature stratifications of day and night (25 degrees C/20 degrees C, day/night) in the dark for 60 d. After soaking in the liquor of GA3 300 mg x L(-1) for 24 h, the P. suffruticos seeds were cultured in wet sand at 15 degrees C for 12-60 days for germination testing. Seed viability was tested by TlC method.
