Objective To investigate and analyze the current setup, operation, nurse staffing,professional ability of nurses and professional standardized training system of tertiary hospitals in Zhejiang.Methods Cross-sectional study was used to investigate the nursing directors and 105 nurses from 36 tertiary hospitals of Zhejiang.The tools included the general questionnaire of anesthesia recovery rooms in Zhejiang tertiary hospitals, anesthesia specialty nurse job description questionnaire, and anesthesia recovery room nurses clinical specialized ability questionnaire.Data of the study were concluded and analyzed in the end.Results 35 of the 36 hospitals surveyed have in place anesthesia recovery care, accounting for 97%.The ratio of recovery room beds to operating bed was 0.48, and the ratio of nurses to recovery room beds was 0.52.In addition to the entire process involvement in the recovery and care of patients during recovery, the job of nurses covers administration of anesthesiology related items, equipment, drug management, cost management and cost entry, pain management and nursing.Nurse training methods depend on continuing education mainly.Anesthesia recovery room nurses′ clinical skills scored in average 82.96±1.52 points.Conclusions Most of these tertiary hospitals have in place anesthesia recovery rooms, yet with such challenges as shortage of beds, and overload/understaffing of nurses.Nurses are mostly trained in the departments, and a system of standardized training and qualification is to be further improved and established for such nurses.

Objective To study the half quantitative diagnostic method of the high-risk gastrointestinal stromal tumors (GISTs) with analyzing the characteristic of high-risk and lower risk GISTs with multi-slice spiral CT (MSCT). Methods CT findings of 46 patients with 51 GIST lesions were retrospectively analyzed. The location, size, shape, boundary, growth pattern and other specialties of the tumors in high-risk and lower risk GISTs were studied, moreover statistical analysis was conducted, logistic regression equation was obtained. Results Significant difference was found in tumors' location, size, shape, boundary and distant metastasis between the two types of GISTs. There were obvious correlation between the risk level and tumors' size and boundary which could be used to build the diagnostic equation of high-risk GISTs. Conclusion The equation ln [P/(1-P)]=-2.612X_3+0.371X_5 (X_3:tumors' boundary, X_5:tumors' size) is valuable in the diagnosis of high-risk GISTs.

Lycopene—a kind of important active compound of caroteinoids, is greatly beneficial to human health with its diverse biological functions. With the elucidation of lycopene biosynthetic pathway and cloning genes of relative enzymes from microorganisms, it is possible to regulate lycopene biosynthesis via genetic engineering. The biosynthesis pathways of lycopene and gene cloning of lycopene biosynthetic enzymes in microorganisms were reviewed, and gene engineering strains documented in previous works including: E.coli and yeast constructed by genetic recombination, mold strains enhanced the ability of producing lycopene by gene manipulation were summarized. At last, compared with the present methods, the problems existed in the process of construction were pointed out.
