中文摘要: 不同基因型/亚型HCV感染患者病程进展和抗HCV治疗效果各异,探明HCV基因型/亚型的分布模式并建立未来HCV基因型/亚型的分布比例预测模型对HCV研究策略的制定具有极强的指导意义,同时也能更好的指导HCV防治体系的建立。但由于各种条件限制,目前尚未见全面系统的类似的研究报道。从地理位置等因素考虑,以西南地区作为试点进行研究具有代表性,我们之前的研究也探讨了西南地区作为试点的现实意义。本项目依靠依托单位自2004年起建立的标本库所收集的大量HCV患者血清样本,采用新近研发的准确研究方法,拟以西南地区作为试点,系统的绘制西南地区HCV病毒株来源和播散模式图,在一定程度上反映HCV病毒株在全国的播散规律,并建立西南地区HCV各基因型/亚型分布比例预测模型。为今后在全国范围内进行类似的研究提供实践和理论基础,并为中国HCV研究方案制定和防控体系建立提供重要的理论依据。

英文摘要: There were significant differences in disease progression and antiviral treatment effect among CHC patients infected with different genotypes/subtypes of HCV. For guiding the HCV research strategies institution and HCV prevention and treatment system construction, the spatial-temporal distribution of HCV genotypes/subtypes should be identified, and the change tendencies in future should be estimated. Due to the poor conditions, there is no similar, large, systematic study at present. Take the geographical factors into consideration, our previous studies have shown that Southwest have great realistic and representative meanings, could have done with a pilot project. Depend on the HCV serum specimens library which established since 2004, applicant use the newly improved, feasible research methods, aim to draw a prediction model about the HCV propagating ways or rules, and predict its dynamic distribution ratios in different genotypes/subtypes. It could be seen as the academic and practical foundation for the later research, and provide a theoretical basic in the system of CHC prevention and treatment as what mentioned before.
