Intervention model description: Select patients with advanced hepatocellular carcinoma who have been clinically consulted by MDT ,those patients will be treated with carrilizumab and apatinib mesylate,and divide them into two groups randomly .Collect the stool specimens and clinical data from those who will be treated with oral bifidobacterium or without bifidobacterium during immunotherapy.
Primary purpose: TREATMENT

Brief summary: This study plans to observe the changes of liver cancer and immune cell subsets by replicating the high abundance intestinal flora and liver cancer mouse model, reveal the relationship and mechanism of intestinal flora in the immunotherapy of liver cancer, and study the impact on prognosis by regulating the positive correlation of lactic acid bacteria and bifidobacteria of rumen coccus in patients with advanced liver cancer receiving immunotherapy

Detailed description: Select patients with advanced hepatocellular carcinoma who have been clinically consulted by MDT,those patients will be treated with carrilizumab and apatinib mesylate, and divide them into two groups randomly .Collect the stool specimens and clinical data from those who will be treated with oral bifidobacterium or without bifidobacterium during immunotherapy.; Use 16S sequencing to detect the changes in the composition ratio of intestinal flora and the level of galactose acid, judge the response to clinical treatment and establish the relationship curve with clinical treatment efficacy.
