Sun Lao believes that this disease belongs to the syndrome of essence deficiency and excess, with qi stagnation, blood stasis and phlegm coagulation as its essence and spleen and stomach deficiency as its essence. The love between healthy deficiency and evil causes "nausea" (stomach cancer).

In the treatment, comprehensive treatment should be adopted, combined with western medicine surgery and chemotherapy to eliminate pathogens and traditional Chinese medicine to strengthen the body resistance, so as to achieve the purpose of anti-cancer and tumor elimination.

In clinical practice, Dr. Sun Lao followed Zhu Danxi's academic thought of "upset stomach": "blood deficiency, qi deficiency, fever, phlegm turbidity" and Zhang Jingyue's academic thought of "nothing more than internal injury, resulting in impaired stomach qi", and proposed that the internal cause of gastric cancer recurrence and metastasis is insufficient vital qi, which leads to accumulation and is easy to accumulate, and the pathological basis is qi stagnation, blood stasis and phlegm coagulation.
