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.

Sudden visual loss is a group of diseases of retina, with emotional factors being an important pathogeny. On the basis of summarizing the relationship between the psychological features of the sudden visual loss and seven emotional factors, we explore the application of the seven emotional factors in sudden visual loss, in order to treat a disease by looking into both its body and mind and enhance its therapeutic effects.

Objective To observe the impact of the five-emotion restrictive therapy on coronary heart disease. Methods109 hospitalized patients with coronary heart disease were randomly divided into a experimental of 56 patients and a control group of 53 patients according to length of stay. The control group was treated with the conventional therapy; the experimental group was imposed five-emotion restrictive psychological intervention on the basis of conventional therapy. The investigation was done using self-rating anxiety scale(SAS) and self-rating depression scale(SDS) on 1 day after admission and ld before discharge respectively. SAS and SDS scores were surveyed. At the same time Holter monitoring and normal ECG test were compared. Results Compared with control group, the experimental group 1 d before discharge of the SAS and SDS scores were (41.9±7.4) and (38.6±8.4), and the difference was statistically significant (P＜0.01) . The total effective rate of Holter monitoring and normal ECG was 64.15％ and 92.85％ in the control and experimental group, and the difference was significant (P＜0.01) . ConclusionThe pathological seven emotions have a certain affection on the incidence of coronary heart disease, treatment and prognosis of the course. Five-emotion restrictive psychological intervention can adjust timely psychological state of patients, eliminate negative emotions, and significantly help the incidence, treatment and prognosis of the disease.

A high-yield arachidonic acid producing strain (mortierella alpina) was selected with ion implantation. After treating the dry-thallus of high-yield arachidonic acid-producing strain with BF3-CH3CH solution, the fatty acid in dry-thallus of arachidonic acid producing strain were analyzed by gas chromatography and mass spectrometry. The result showed that there were saturated and unsaturated fatty acids in the dry-thallus. The relative content of arachidonic acid is 70.2% in the all fatty acids. In addition, there were oleic acid, linoleic acid and γ-linolenic acid in the dry-thallus.
