贵州省农村信息化服务现状实证分析与发展对策

[目的]为深入了解贵州省农村信息化服务现状,以期更科学地探索与设计贵州省农村信息化服务模式,为广大农民提供优质的信息服务.[方法]对贵州省所有地州市典型县份、典型乡（镇）和行政村的农户以进村入户、现场调查、走访、座谈和发放问卷等方式进行实地调查和数据采集,并利用SPSS 19.0统计分析软件对数据进行分析处理.[结果]贵州省农村信息化服务基础设施建设成效显著、信息传播渠道呈立体化发展、信息服务内容丰富.但也存在基础设施运行效率不高、信息传播渠道不够畅通、信息资源质量不高、信息支付意愿不强等问题.[建议]应加大基础设施建设力度、提高基础设施利用率,整合各种信息传播途径、畅通信息服务渠道,加大信息资源建设力度、提高信息内容质量,加强教育力度、提高信息意识,以推动贵州省农村信息化服务快速发展.

Effects of remifentanil on monophasic action potential and transmural dispersion of repolarization in rabbit myocardium

AIM: To study the effect of remifentanil on monophasic action potential and transmural dispersion of repolarization (TDR) in the 3-layer myocardium of isolated rabbit hearts. METHODS: Adult rabbits (n=18, 2.0 ~ 2.5 kg) were used to isolate the hearts for preparing Langendorff perfusion model. The hearts were randomly divided into 3 groups after perfusion with K-H solution for 15 min: the perfusion in control group (C group) continued for 60 min; the hearts in remifentanil group (R group) were perfused with 12 μg/L remifentanil K-H solution for 60 min; the hearts in remifentanil+aminophylline group (RA group) were given 60-min perfusion of 12 μg/L K-H remifentanil+30 mg/L aminophylline. The HR and 3 layers of myocardial monophasic action potential (MAP) in the left ventricular anterior wall were recorded at time points after balanced infusion for 15 min (T₀), and continued perfusion for 15 min (T₁), 30 min (T₂) and 60 min (T₃). The monophasic action potential duration of repolarization at 90% (MAPD₉₀) and the transmural dispersion of repolarization (TDR) were calculated. The early afterdepolarization, delay afterdepolarization and arrhythmia were also observed. RESULTS: In R group, slower HR and prolonger MAPD₉₀ and TDR at T₁~T₃ were observed as compared with those at T₀ (P<0.05). R group showed slower HR and longer MAPD₉₀ and TDR than C group and RA group (P<0.05). CONCLUSION: Remifentanil slows the HR, extends the MAPD₉₀ and increases the TDR, thus being prone to induce reentry. Aminophylline makes HR faster and MAPD₉₀ shorter, thereby reducing the TDR.
