To strengthen nursing ethics education and nursing construction are the solid foundation for successful emergency nursing.This paper analyzes the demand for building a reasonable nursing echelon,explores problems in current condition,and comes up with feasible countermeasures,thus providing reference for strengthening nursing echelon construction.

Objective To decrease misdiagnosis and to improve the correct diagnostic rate of mammary tuberculosis .Methods 9 cases of mammary tuberculosis proved by operation and pathology misdiagnosed as other diseases were retrospectively analyzed.Results Among 9 cases,5 cases were misdiagnosed as mammary cancer,1 case as chronic mammary inflammation,1 case as mammary abcess,1 case as mammary hyperplasia,1 case as mammary fibroadenoma.Conclusion The reasons leading to misdiagnosis are unsuitable methods of examinations,lack of solid basic knowledge,and lack of experience.

Objective: To investigate the correlation between gastric acid pH value of patients with acid-related gastric diseases and the score of their life events. Methods: To evaluate the LES (life event scale) of the 108 patients with acid-related diseases were divided into 3 groups according their cluster of gastric acid pH value, group one pH 1.3 (n=37), group two pH 1.6~1.7(n=32), group three pH 2.1~4.5(n=39). Results: The LES total score and factor scores increased with the gastric acid level, the total score of the three groups were 40.0?20.6, 15.1?9.2, 6.4?6.5 respectively, the differences among the three groups were significant (F=43.26,P

OBJECTIVETo investigate the intestinal absorption kinetics of gambogic acid (GA) in rats.

METHODIn situ single-way intestinal perfusion model was established to study the intestinal absorption kinetics of GA in different absorption segments, and the concentration of GA in the perfusate was determined by HPLC. The effect of drug concentrations on intestinal absorption was also detected.

RESULTGA showed a higher absorption rate than other intestinal segments (P < 0.05) and kept unchanged in duodenum after addition in drug concentration.

CONCLUSIONGA can be absorbed in all intestinal segments in rats with the higher absorption rate in duodenum. Its mechanism is passive diffusion.

Objective Aims to reduce the hidden risks of laboratory biosafety,understand the status of biosafety laboratory record filing situations in Shenzhen,and also to provide scientific basis for further standardizing the management of biosafety laboratory in Shenzhen.Methods In 2017,75 laboratories in Shenzhen completed record filing were surveyed,method ologies adopted including application materials review,phone call consultation and communication,carrying out corrective ac tions based on feedback peer review suggestions and finally complete the record filing.Results The first/second level laborato ry of biosafety in shenzhen is mainly public medical institutions,followed by private hospitals.In 2017,the first three recordfiling LABS were Futian district,nanshan district and longgang district.According to the data analysis,lack of the second category of pathogenic microorganism laboratory activity project risk assessment report,and laboratory layout diagram function partition is not clear were two of the more prominent problems in the software and hardware of laboratory management respectively.Conclusions Basically,the overall record filing of Shenzhen biosafety laboratory is good,however,more measurements should be developed to deal with identified problems to further strengthen the standardized management of laboratory biosafety.

Chronic diabetic wound remains a critical challenge suffering from the complicated negative microenvironments, such as high-glucose, excessive reactive oxygen species (ROS), hypoxia and malnutrition. Unfortunately, few strategies have been developed to ameliorate the multiple microenvironments simultaneously. In this study, Chlorella sp. (Chlorella) hydrogels were prepared against diabetic wounds. In vitro experiments demonstrated that living Chlorella could produce dissolved oxygen by photosynthesis, actively consume glucose and deplete ROS with the inherent antioxidants, during the daytime. At night, Chlorella was inactivated in situ by chlorine dioxide with human-body harmless concentration to utilize its abundant contents. It was verified in vitro that the inactivated-Chlorella could supply nutrition, relieve inflammation and terminate the oxygen-consumption of Chlorella-respiration. The advantages of living Chlorella and its contents were integrated ingeniously. The abovementioned functions were proven to accelerate cell proliferation, migration and angiogenesis in vitro. Then, streptozotocin-induced diabetic mice were employed for further validation. The in vivo outcomes confirmed that Chlorella could ameliorate the undesirable microenvironments, including hypoxia, high-glucose, excessive-ROS and chronic inflammation, thereby synergistically promoting tissue regeneration. Given the results above, Chlorella is considered as a tailor-made therapeutic strategy for diabetic wound healing.

【Objective】 To study the annual financial expenditure in blood stations with different scales, and to establish the regression equation between blood collection units and total expenditure. 【Methods】 The annual total expenditure, the per capita cost of serving population, as well as the collection units of whole blood and apheresis platelet of 24 blood stations were collected. The financial expenditure required for collecting 10 000U blood was calculated.The statistical analysis was carried out with SPSS statistical software. 【Results】 From 2017 to 2020, the total annual financial expenditure of 24 blood stations showed an upward trend. The total expenditure among blood stations was different. The per capita cost of servicing population in the areas where the 24 blood stations were located had been increasing year by year. The 24 blood stations were divided into two grades according to the blood collection volume as 50 000 U, and the relationship equation between the blood collection volume and the annual total expenditure had been established. After testing, each equation was effective(P<0.05); There was no difference in the financial expenditure required for collecting 10 000U blood among blood stations with different scales. 【Conclusion】 From 2017 to 2020, the blood stations with an annual collection volume more than 50 000 U demonstrated a higher financial expenditure and the per capita cost of serving population than those <50 000 U. The blood collection volume of blood stations is significantly correlated with the annual total expenditure and the per capita cost of serving population.
