• Renal function: serum creatinine is greater than 1.5 times that of ULN;

• Other abnormal laboratory test results, which may affect the subject's completion of the test or interfere with the test results as assessed by the investigator; Test could be repeated during the screening period for the false individual test results, or value near the limit, or inconclusive results, or according to the investigator's judgement. After re-test, subjects should not be randomized if the results still meet the above conditions;

22. Patients showed positive for hepatitis C virus (HCV) antibodies, or human immunodeficiency virus (HIV), or anti-syphilis spiral antibody (TP-Ab) [rapid plasma reagin ring card test (RPR) or toluidine red unheated serum test (TRUST) negative can be enrolled], or hepatitis B virus surface antigen (HBsAg);

• Patients showed HBsAb negative and HBcAb positive, HBV-DNA test is required. If HBV-DNA result showed negative or below the upper limit of normal, the patient can be enrolled;
