Transgenic Bt rice has been shown to be an effective means of controlling Lepidoptera pests of rice. However, the potential roles of transgenic rice on planthoppers and their predators need to be investigated before its commercialization. Population density, species dominance and population dynamics are important parameters of arthropods populations in field. So the impacts of three transgenic Bt rice strains expressing crylAb/crylAc, crylC and cry2A on population density, species dominance and population dynamics of three species of planthoppers （Nilaparvata lugens, Sogatella furcifera and Laodelphax striatellus） and their three main predators （ Cyrtorhinus lividipennis, Pirata subpiraticus and Theridium octomaculatum） were evaluated at three sites in Hubei Province, China, in the current study. The results showed that among three species of planthoppers, both in transgenic and non-transgenic rice field, the predominant species ofplanthoppers within phytophagous guild was S. furcifera at any site either growing season （46-50%）. Significantly higher population density ofN. lugens was observed in T2A-1 field relative to Minghui 63 field at Wuxue in 2010. The species dominance of predator, P. subpiraticus, in tt51 field was significantly higher than that in T 1 C-19 and T2A-1 fields in 2009 at Xiaogan site. Sampling date significantly influenced six arthropods except for P. subpiraticus in 2010. The interaction between rice strain^sampling date had no significant adverse effects on the population dynamics of three species of planthoppers and their predators, except for several individual species in 2009. The interaction among rice strain^sampling date^sampling site also had no significant effect on six arthropods except for S. furcifera in 2009. The results indicated that transgenic Bt rice expressing crylAb/crylAc, cry2A and crylC had no significant adverse effects on the population dynamics of three planthoppers and their predators in most investigated data and samp

Background: The role of human multidrug resistance gene (MDR1) SNPs in the interindividual variability of imatinib mesylate (IM) response has received considerable attention. We aimed to study the association between SNPs of the MDR1 gene (C1236T, G2677T/A, C3435T) and IM response in chronic myeloid leukemia (CML) patients. Method: A retrospective case-control study was conducted on 48 patients with CML undergoing IM therapy. All patients were genotyped using PCR-RFLP method. Results: The genotype and allele frequencies of C1236T and C3435T were not significantly different between CML patients responders and non-responders to IM (p > 0.05). The frequencies of 2677T allele and 2677tt genotype were significantly increased in CML patients IM responders which as compared with IM non-responders (50% vs 26.9%, p = 0.013 and 27.3% vs 3.8%, p = 0.029 respectively). Whereas the 2677AA genotype and CAC haplotype were found only in CML patients IM non-responders (15.4%). Conclusion: Pretreatment genotyping of G2677A/T appears to be useful for predicting IM resistance, which may allow the best choice of drug treatment for CML patients.

目的观察沙棘总黄酮(total flavones ofHippophae rhamnoides,TFH)对角叉菜胶所致大鼠尾静脉血栓的影响,并分析其作用机制。方法采用后足跖部皮下注射角叉菜胶0.25 mL/100g制备SD大鼠尾静脉血栓模型,观察24,36,72 h大鼠血栓发生率与黑尾长度。将60只大鼠随机分为沙棘总黄酮高、中、低剂量组及模型对照组、阳性对照组(阿司匹林组)和正常对照组,每组10只。各实验组动物均灌胃1次/d。30 d后测定各组大鼠凝血酶原时间(PT)、活化部分凝血活酶时间(APtt)、凝血酶时间(tt)、125I-血栓素B2(TXB2)、125I-6-keto-前列腺素F1a(6-keto-PGF1a)水平以及血清一氧化氮(NO)含量。结果沙棘总黄酮能显著缩短大鼠黑尾长度,增加血浆PGI2/TXA2比值,延长tt,APtt时间,并可升高NO含量。结论沙棘总黄酮对角叉菜胶所致大鼠炎性血栓形成具有预防作用,其作用机制可能与提高PGI2和NO水平有关。
