A Study to Evaluate the Pharmacokinetics of Apatinib in Subjects With Impaired Renal Function

The primary objective of the study is to compare the pharmacokinetics of apatinib in subjects with impaired renal function and healthy subjects, to give dose recommendations for patients with impaired renal function.

* In good health, except for kidney disease and complications, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG;
* Agree to take approved method of contraception during the clinical trail and 8 weeks after the last dose of apatinib. Female subject should be negative in the pregnancy test;

for healthy subjects:

* Able to comprehend and willing to sign an informed consent form (ICF)
* 18-70 years of age.
* 19 kg/m2\<BMI \<19-28 kg/m2
