As an immune checkpoint protein expressed by diverse cancer cells, programmed death ligand 1 (PD-L1) facilitates immune evasion by interacting with programmed cell death-1 (PD-1) on T cells. Despite the clinical benefits observed in various cancer types, strategies targeting PD-1/PD-L1 have demonstrated limited efficacy in gastric cancer (GC). Furthermore, the regulation of PD-L1, especially at post-translational modification levels, remains largely unknown.

The death of patients with GC is mainly caused by the metastasis, recurrence, and chemotherapy resistance of GC cells. The cancer stem cell theory defines cancer stem cells (CSCs) as a key factor in the metastasis, recurrence, and chemotherapy resistance of cancer.

The effect of CLDN10 expression in gastric cancer, however, has yet to be elucidated. Differential expression of CLDN10 at the mRNA and protein levels was evaluated using Oncomine, ULCAN, HPA and TIMER2.

In this study, we found that about 30% of tumor-infiltrating lymphocytes (TIL) in the tumor microenvironment of gastric adenocarcinoma were CD69CD103 Trm cells. Trm cells were low in patients with metastasis, and the presence of Trm cells was associated with better prognosis in patients with gastric adenocarcinoma.

To investigate the reasons of anastomotic leakage following learning curve by laparoscopic anterior resection of rectal cancer. Methods: From December, 2011 to March, 2015, the clinical information of 179 patients in our hospital who underwent dixon of rectal cancer were collected. The patients were divided into a laparoscopic learning group, a laparotomy group and a laparoscopic group.

Objective: To evaluate the efficacy of self-made gasbag double-cannula stool drainage device for prevention of anastomotic leakage following anterior resection.
Methods: Clinical data of 169 rectal cancer patients in the 8th Affiliated Hospital of Sun Yat-sen University between October 2010 and October 2016 were retrospectively analyzed. Among them, a self-made gasbag double-cannula stool drainage device was placed in 71 patients(stool drainage group), and the remaining 98 patients were taken as control.
