Inclusion criteria

Inclusion criteria: 1. Subjects with histological or cytologically confirmed malignancy; 2. Age: 18-70 years old, both male and female; 3. Eastern Cooperative Oncology Group (ECOG) physical status score of 0-3; 4. The general situation is acceptable; 5. Complete relevant clinical data; 6. Presence of cancer-related pain, i.e., numeric rating scale (NRS) score recorded in the first 24 hours>=4; 7. Diagnosis of cancer pain in opioid-tolerant patients, including refractory cancer pain; Opioid tolerance is defined as: Received opioid therapy for one week or more and meets any of the following: (1) >=25mcg/h fentanyl patch; mcg mcg: 1mcg=0.001mg; (2) > = 60 mg morphine per day; (3) Oral administration of >=30 mg of oxycodone orally daily; (4) Oral >=8mg hydromorphone daily; (5) Use of another opioid at the same analgesic dose as described above; The equivalent converted dose of commonly used opioids is: oral morphine tablets 60 mg = oxycodone tablets 30~40 mg = morphine injection 20 mg = hydromorphone injection 3 mg = sufentanil injection 20 µg; 8. Patients can eat orally normally; 9. With the consent of the person and signed the informed consent form, willing and able to comply with the planned visits, research treatment, laboratory tests and other trial procedures.

Exclusion criteria

Exclusion criteria: 1. Those who cannot eat orally normally; 2. Patients with poor general conditions, such as ECOG score > 4; 3. Patients with gastrointestinal perforation, acute pancreatitis, acute intestinal obstruction, acute cerebral infarction, acute fever, acute and chronic infectious diseases, and those who use antibiotics within 72 hours; Those who use traditional Chinese medicine within 72 hours; 4.
