Tropical montane rain forest was investigated in Mengsong, south-west to Jinghong City ofXishuangbanna region in the south of Yunnan near the border between China and Myanmar. There are 623 species of seed plants belonging to 327 genera and 116 families in this forest. Analysis of areal types shows that 32.8% of the families are of tropical and subtropical type, 23.3% tropical to temperate type, and 18.1% typically tropical type. Areal types at generic level mostly are tropical (81.4%), in which 28.4% are of Indo-Malaysian type and 26.8% are of pantropic type.

Chronicity maybe result from many factors with complex mechanism.HCV may evade the host immune surveillance due to the hypermutation of HCV gene; HCV has the nature of pantropic,the tissues outside liver can provide virus for repeatedly infection of liver; The HCV receptors,such as CD81,LDL receptor,scavenger receptor B type I,L-SIGN,DC-SIGN and so on,may influence organism humoral immunity and the cellular immunity function in different degrees; HCV infection also may cause the reduction of quantity of organism immune cell or functional defect,low response of humoral immune response,tolerance of cellular immunity,then,the host finally transforms into chronic infection condition.

其慢性化的机制非常复杂，是由多个因素造成的，HCV因其基因高变性可以逃避宿主的免疫监视；HCV具有泛嗜性，肝外组织又可为肝组织的反复感染提供病毒来源；CD81、LDL受体、清道夫受体B类Ⅰ型及L-SIGN、DC-SIGN等HCV受体又可不同程度地影响机体的体液免疫和细胞免疫功能；HCV感染亦可直接导致机体免疫细胞数量减少或功能缺陷，体液免疫应答水平低下、细胞免疫耐受，宿主最终转变为慢性感染状态。
