Methods： A total of 120 cases of gastric cancer patients undergoing chemotherapy were selected and divided into the observation group and the control group according to the random number table method，60 cases in each group. During the chemotherapy，the control group was given routine western medicine nursing， and the observation group was additionally given routine nursing of Chinese medicine based on the treatment of the control group. The nursing effect and the incidence of postoperative complications in the two groups were compared. Results： After nursing， the scores of Self- rating Anxiety Scale(SAS) and Self- rating Depression Scale(SDS) in the two groups were decreased when compared with those before nursing，and the above scores in the observation group were lower than those in the control group， differences being significant(P＜0.05). After nursing， the Chinese medicine symptom scores in the two groups were decreased when compared with those before nursing，and the score in the observation group was lower than that in the control group， differences being significant(P＜0.05). After nursing，the scores of social function，role function，body function，emotional function and the whole function in the two groups were all increased when compared with those before nursing，and the above scores in the observation group were all higher than those in the control group，differences being significant(P＜0.05). The incidence of complications was 31.67% in the observation group，significantly lower than that of 56.67% in the control group，the difference being significant(P＜0.05). Conclusion：The application of routine nursing techniques of Chinese medicine has better effect on gastric cancer patients undergoing chemotherapy， which can effectively prevent postoperative complications， improve their negative emotions， and is worthy of clinical promotion and application.
