This paper briefly described the present state of the use of major medical equipment in an island hospital. The intermittent idleness of the equipment increased the difficulty of maintenance. The gap between the current medical and equipment preparation, such as reagents, instruments, and equipment, and the demand for medical support was a major obstacle for diagnosis and treatment. Harsh climate, incomplete hospital information system, and poor handover process of medical staffs during rotation were the main challenges for medical equipment management in remote island hospitals. It is suggested that the island hospital improve its management regulation of medical instruments and equipment, ensure sufficient stock of key equipment and reagents, establish a regional medical consortium model to make full use of remote consultation and artificial intelligence in medical imaging, and make reasonable use of hospital ships to balance and coordinate medical resources for island hospitals, so as to effectively improve the medical support capacity on islands.

Objective To investigate the prognostic value of neutrophil changes in patients with colorectal cancer.Methods The neutrophils in patients with colorectal cancer were classified into twotypes:peripheral blood neutrophils and tumor-associated neutrophils (TANs).Peripheral blood neutrophils are expressed as neutrophil/lymphocyte ratio (neutrophil to lymphocyte ratio,NLR).Results The 5 year's survival rates of patients with high and low NLR were 75.2％ and 88.2％,respectively.The 5 year's survival rates of patients with high and low TANs were 97.6％ and 64.2％,respectively.The survival rates of patients with low NLR and high TANs;high NLR and high infiltrating TANs;low NLR and low infiltrating TANs;and high NLR and low infiltrating TANs were respectively 100％,95.7％,76.4％ and 53.5％.With the two joining together the ability to distinguish long-term prognosis of patients was significantly better than any one alone.Multivariate regression analysis showed that,high peripheral blood NLR,low TANs infiltration,tumor located in the rectum,TNM staging are independent risk factors for colorectal cancer prognosis.Conclusions NLR in preoperative peripheral blood combined with infiltrating TANs in colorectal cancer tissues can be used as a prognostic indicator for patients with colorectal cancer.High NLR in preoperative peripheral blood combined with low infiltrating TANs in colorectal cancer tissue predicts poor prognosis.
