We found that the content and distribution of WBC, HTC, HGB, MCV, SD, PLT, ALB, alt, AST, TBIL, direct bilirubin, GGT, ALP, CEA, and CA199 in group B were within the normal range (Figure 1(a)), indicating that there was no significant change in the blood routine of patients with gastric cancer, and the content and distribution of total protein TP were generally lower than the normal range, In addition, we also measured the contents of tumor markers CEA and CA199. This evidence concerns the gene ALB and gastric cancer.
