• (7) Confirmed or highly suspected of acute infectious diseases such as viral hepatitis activity , or clinically confirmed active tuberculosis;
• (8) Patients with sinus bradycardia (less than 60 per minute);
• (9) Uncontrolled bleeding in the past 24 hours（Clinical judgment requires transfusion support）;
• (10) Large area burns or chemical burns (III degree burns area > 30% BSA);

• (16) Participated in clinical intervention test in 3 months;
• (17) The subject is a researcher or his immediate family member, or may have improper informed consent;
• (18) The investigator considers it inappropriate for the patient to participate in this test.
