4. Cirrhosis, decompensated liver disease, active hepatitis or chronic hepatitis need to be treated with antiviral treatment;
5. Renal failure requires hemodialysis or peritoneal dialysis;
6. The control of diabetes mellitus was not good (FBG) was more than 10mmol/l;
7. The routine urine suggested that the urine protein was ≥ + +, and the 24-hour urine protein was more than 1.0 G;

8\) Patients with any signs of bleeding constitution or history, regardless of severity; In the 4 weeks before entering the group, there were unconnected wounds, ulcers or fractures in patients with bleeding or bleeding events ≥ CTCAE Level 3;
9\) The patients with arteriovenous thrombosis occurred within 6 months, such as cerebrovascular accidents (including transient ischemic attack), deep vein thrombosis and pulmonary embolism;
