All-trans retinoic acid injection and application

The invention belongs to the technical field of biological pharmacy, and particularly relates to an all-trans retinoic acid injection and application. The all-trans retinoic acid injection includes all-trans retinoic acid and hydrotropic molecules. According to the prepared all-trans retinoic acid injection, the apparent solubility of the all-trans retinoic acid is increased from 0.01 mg/ml in theprior art to 0.1 mg/ml or above, and at least increased by 10 times. By applying the injection, the activity of infiltrative immunosuppression cell mass in blood and tumor tissues of patients suffering from tumors can be reduced, the immune elimination effect of mechanism special for the tumors is improved, by using the injection alone or using the injection with the cooperation of other drugs for application, the growth and recurrence of the tumors can be suppressed, and therefore the all-trans retinoic acid injection has great medical practicability. 本发明属于生物制药技术领域，具体涉及种全反式维甲酸注射剂与应用。所述全反式维甲酸注射剂包括全反式维甲酸和助溶分子，本发明所制备的全
