Objective: Uric acid is a kind of end product of purine metabolism extrinsic source and endogenous, it's dissolvability and degree of saturation in the blood is limited, the maximum degree of saturation is 416μmol/L, crystal will emerge when surpass this density. About 25% of uric acid excrete through digestive canal, the rest through kidney, the condition of it's egestion through kidney roughly as follows:(1) Almost 100% of the blood uric acid is filtered through the glomcrulus;(2)98%～100% of the uric acid which is filtered will be reabsorb in the proximate nephric tubule;(3) The nephric tubule initiatively secrete uric acid to the lumens of nephric tubule;(4) Part of the secreted uric acid will be reabsorbed to the blood around the nephric tubule.

The reason is the tumor cells escape the immunosurveillance whose mechanism is very complex. In general, the explanation is based on two aspects, one is that the tumor cells can passively escape the host immunosurveillance when the host immnue state is low and another is tumor cells can actively secrete factors to down-regulate immune function.

肿瘤逃避免疫监视的机制非常复杂，但总体上可从宿主免疫状态及肿瘤细胞等方面来解释，在宿主免疫状态低下时，肿瘤细胞可以被动地逃避免疫监视，但是肿瘤细胞也能主动地释放一些活性物质，下调免疫杀瘤作用，该作用主要通过两个途径，即对免疫细胞功能的调节和免疫细胞数量的调节。

For most piercing-sucking insects, they will secrete gell saliva and watery saliva when they feed on plants. The gell saliva will be secreted at the early stage of feeding to form salivary sheath, which is supposed to surround and protect the stylet. This saliva can help piercing-sucking insects to feed on plants directly and indirectly. Meanwhile, the watery saliva contains many components like pectnase, cellulose, polyphenol oxidase, peroxidase, alkaline phosphatase, sucrase, etc. These components can help piercing-sucking insects in plant tissue penetration, food digestion, detoxification of plant secondary substances and break-down of plant defence reaction.
