高效固体缓释型阻垢剂的研制及性能分析

针对大庆油田集输管道腐蚀结垢现象,以主剂、分散剂、特殊缓蚀阻垢剂和载体配制固体缓蚀阻垢剂,通过复配试验筛选出适合其采出液水质的药剂,并对其缓蚀和阻垢性能进行分析。结果表明:加注药剂后的管道钢腐蚀速率为0.070mm/a,远低于未加注前的0.310mm/a;阻垢效果15天内稳定,阻垢率约为91%,阻垢性能良好;缓释速率为约每10天溶解8%,加注周期约为3个月。所制备药剂性价比高,缓蚀阻垢综合性能良好,可作为油田水驱采出液专用缓蚀阻垢药剂。

乙肝疫苗苦参素拉米夫定联合治疗慢性乙型肝炎的临床研究

目的探讨乙肝疫苗苦参素拉米夫定联合治疗慢性乙型肝炎的临床疗效。方法随机选择62例慢性乙型肝炎患者分为治疗组31例,苦参素0.2tidpo。疗程7～9个月,乙肝疫苗60ug,每15天1次,皮下注射,疗程12个月,拉米夫定0.1qdpo.疗程12个月。对照组31例单用拉米夫定0.1qdpo。疗程12个月。疗程中定期检测血常规、谷丙转氨酶(ALT)、HBeAg、抗-HBe、HBV、DNA。结果全部患者完成1年治疗。治疗组ALT复常率,HBeAg/抗-HBe血清转换率、HBVDNA阴转率明显高于对照组(分别为80.6%和51.6%,P<0.05;45.2%和19.4%,P<0.05;77.4%和51.6%,P<0.05)。结论乙肝疫苗、苦参素、拉米夫定联合治疗慢性乙型肝炎疗效优于单用拉米夫定。     

小眼井压裂液的延迟交联技术

根据小眼井的特点和技术要求,研制了可控制交联时间的延迟交联剂DCL-KB,该剂是硼与特殊的配位络合体在常温下合成的,比普通硼砂分子大得多的络合物。对DCL-KB的耐温性、剪切恢复性、破胶性、携砂等性能进行了评价。结果表明,DCL_KB交联剂耐温耐剪切性能好,调节加量和胶液的pH值,可改变延迟交联时间。以DCL-KB为主剂的压裂液耐温耐剪切性能好、滤失量小、破胶快速彻底,而且具有良好剪切恢复能力,可满足小眼井压裂的需要。

Removal of Nonspecifically Bound Proteins on Microarrays Using Surface Acoustic Waves

Nonspecific binding of proteins is an ongoing problem that dramatically reduces the sensitivity and selectivity of biosensors. We demonstrate that ultrasonic waves generated by surface acoustic wave (SAW) devices remove nonspecifically bound proteins from the sensing and nonsensing regions of the microarrays. We demonstrate our approach for controllably and nondestructively cleaning the microarray interface. In this work, SAWs were generated using 128 YX lithium niobate, chosen for its high coupling coefficient and efficient power transfer to mechanical motion. These waves propagating along the surface were coupled into specifically bound and nonspecifically bound proteins on a patterned surface of 40 mum feature size. Fluorescence intensity was used to quantify cleaning efficacy of the microarrays. Our results have shown that excess protein layers and aggregates are removed leaving highly uniform films as evidenced by fluorescence intensity profiles. Selected antigen-receptor interactions remained bound during the acoustic cleaning process when subjected to 11.25 mW of power and retained their efficacy for subsequent antigen capture. Results demonstrate near-complete fluorescence signal recovery for both the sensing and nonsensing regions of the microarrays. Of significance is that our approach can be integrated into existing array technologies where sensing and nonsensing regions are extensively fouled. We believe that this technology will be pivotal in the development and advancement of microsensors and their biological applications.
