ETPNav: Evolving Topological Planning for Vision-Language Navigation in Continuous Environments.

Vision-language navigation is a task that requires an agent to follow instructions to navigate in environments. It becomes increasingly crucial in the field of embodied AI, with potential applications in autonomous navigation, search and rescue, and human-robot interaction. In this paper, we propose to address a more practical yet challenging counterpart setting - vision-language navigation in continuous environments (VLN-CE).

[Risk factors of postoperative complications of pancreatoduodenectomy].

Background & Objective: Pancreatoduodenectomy is the main treatment for pancreatic carcinoma and periampullary carcinoma. This study was to explore risk factors of postoperative complications of pancreatoduodenectomy for pancreatic carcinoma and periampullary carcinoma.

Methods: Clinical data of 94 patients with pancreatic carcinoma or periampullary carcinoma, underwent pancreatoduodenectomy at the second affiliated hospital of Guangzhou Medical Collage and Gansu Provincial Tumor Hospital from Jan.

[CK20 mRNA expression in peripheral blood of patients with gastrointestinal carcinoma and its clinical significance].

Background & Objective: Detecting expression levels of cytokeratin 19 (CK19), CK20, MUC1, and carcinoembryonic antigen (CEA) in peripheral blood,lymph node,and bone marrow is a major method for diagnosing micro-metastasis in patients with gastrointestinal carcinoma of early stages. This study was to examine the expression, before and after operation, of CK20 mRNA in peripheral blood of patients with gastrointestinal carcinoma, to further explore hematogenous-spread micro-metastasis status of these patients, and significance of CK20 mRNA detection in treatment during perioperation period.

Methods: Peripheral blood samples were collected before, and 2 weeks after operation from 62 patients with gastrointestinal carcinoma,and 22 controls (12 patients with benign gastrointestinal disease, and 10 healthy volunteers).

[Effects of short-term treatment of somatostatin on angiogenesis of gastric carcinoma].

Background & Objective: It is a hot spot in tumor therapies to inhibit the angiogenesis of carcinoma. Our current study was designed to investigate the inhibitory effect of somatostatin analogue on the angiogenesis of gastric carcinoma by hypodermic injection.

Methods: Twenty-five patients who have positive expression of vascular endothelial growth factor(VEGF) and somatostatin receptor 2(SSTR2)were selected by gastroscopic biopsy and immunohistochemical staining before surgical operation.
