The process of liver metastasis of colorectal cancer includes tumor cells invasion,survival in blood stream,extravasation to the liver and proliferation. It is involved in series of molecular markers,among which vascular endothelial growth factor and endothelial growth factor receptor are the major targets.

Objective:To construct an early comfort assessment and management plan for ICU patients with high flow nasal cannula, and to provide reference for clinical nursing practice and management.Methods:The domestic and foreign databases were retrieved, and the literatures on high flow nasal cannula were obtained and evaluated. The first draft of the early evaluation and management scheme of nasal high-flow humidification oxygen therapy was developed. Two rounds of expert consultation were conducted by Delphi method.Results:The early comfort assessment and management plan for ICU patients with high flow nasal cannula was formed, including 3 primary indicators, 12 secondary indicators, and 32 tertiary indicators. The authoritative coefficients of 2 rounds of expert consultation were 0.915 and 0.931, respectively. The coordination coefficients were 0.221, 0.130 and 0.278( χ 2 values were 8.000, 27.140, 163.824, P<0.05 or 0.01). Conclusions:The early comfort assessment and management plan of ICU patients with high flow nasal cannula are consistent with the advice of experts at all levels. The enthusiasm and authority of the experts is high, which provides a basis for the scientific management of ICU patients with nasal high-flow humidification oxygen therapy.

Precision medicine is becoming the goal of translational research on colorectal cancer. Accurate molecular subtyping contributes to better guidance of clinical practice. The current TNM staging system of colorectal cancer is inadequate in terms of guiding clinical practice, such as the underestimation of prognosis of with stage II( and III( colorectal cancer TNM staging, and identification of high-risk and low-risk patients with stage II( colorectal cancer. Researchers from Europe and US have proposed a number of molecular subtypings with clinicopathological phenotypes and molecular phenotypes, which has certain practical significance and is beneficial to the choice of treatment regimen and targeted drugs. But the current results of subtyping research require further validations by clinical large scale multi-center trials. Based on precision medicine, molecular subtyping gradually reveals its clinical significance and is optimized through combining genomics with various clinical phenotypes, indicating its guidance for clinical practice, which is the inevitable course of precision medicine accomplishment. In recent years, there have been many new advances in colorectal cancer liver metastasis treatment. The prognosis of colorectal cancer patients undergoing resection of liver metastasis lesion is similar to those with stage III(. Early recurrence within 6 months after translational treatment and resection occurred in about one third of the patients with initially unresectable liver metastasis, and the overall survival was poor. Thus, an evaluation system should be established in order to avoid the strong therapy and strive for better quality of life in some patients. Individualized treatment for colorectal cancer is emphasized increasingly. Body fluid (peripheral blood and urine) marker detection is a recent research hotspot, including serum protein(polypeptide), plasma miRNA, circulating tumor cells and circulating nucleic acid.
