Thrombocytopenia is common in patients with malignancies, especially in mid- to late-stage cancers. Decreased platelets increase the risk of bleeding, and severe reduction deprives patients of chemotherapy and radiotherapy. Western medicine mainly uses drugs such as interleukins to boost platelets or direct platelet transfusion, which treats the symptoms but not the root cause. Chinese medicine alone or in combination with western medicine can make up for the shortcomings of western medicine. 1.Case example Wu Moumou, male, 48 years old. 2013-11-29 for “acute cerebral infarction” check abdominal ultrasound found “liver occupancy, left upper abdominal occupancy”, laboratory tests: platelet count 58×109/L. 2013-12-2 further PET-CT of the whole body revealed: pancreatic tail cancer, multiple metastases in the liver and splenomegaly. On 2012-12-11, he was admitted to our hospital for the treatment of “pancreatic cancer and liver metastases”, and his cerebral infarction symptoms were significantly relieved after treatment with drugs to improve brain metabolism and nerve nutrition. Magnetic resonance imaging showed that pancreatic tail cancer (range 4.7×7.2×157.5px) with multiple metastases in the liver (maximum lesion diameter 3.6×107.5px) and splenomegaly. After 5 days of treatment with western medicine “recombinant human interleukin-11 for injection” to raise platelets because of low platelets, on 2013-12-19, laboratory tests were performed: white blood cell count 3.25×109/L, hemoglobin 92.0g/L, platelet count 50×109/L. Platelets decreased instead of increased, and western medicine treatment was ineffective. He was treated with Chinese medicine. The symptoms were: fatigue, decreased appetite, bleeding, red tongue with tooth marks, yellow thick and greasy moss, weak ulnar pulse and slippery Guan pulse. Chinese medicine identifies the symptoms as: deficiency of both lung and kidney, internal dampness and heat. The formula: Radix Codonopsis Pilosulae 30g, Radix Astragali 20g, Fructus Lycii 10g, Dendrobium 10g, Radix Rehmanniae 20g, Rhizoma Dioscoreae 30g, Poria 10g, Coix Coix Seeds 30g, Patchouli 10g, Radix Rehmanniae 10g, Dampness 10g, Pericarpium Citri Reticulatae 6g. One dose daily with water decoction. 2013-12-25 Laboratory tests: white blood cell count 4.93×109/L, hemoglobin 104g/L, platelet count 70×109/L. The patient was discharged from the hospital satisfied with the medicine. 2.Experience Western medicine can cure the disease, Chinese medicine can also cure the disease, sometimes the effect of Western medicine treatment is not good, and then turn to Chinese medicine treatment can be effective. After taking Chinese medicine, not only did the platelets increase, but also the white blood cells and hemoglobin increased, and the patient’s symptoms also improved. Chinese medicine treatment is individualized, each patient’s condition is different, the evidence type is different, therefore the prescribed herbal prescription is also different, if the evidence type of other patients is different from this patient, then taking the prescription is ineffective. Chinese medicine can be used not only alone but also together with western medicine, which can reduce the adverse effects of western medicine and increase the effect of western medicine.
