Objective:Along with general hospital assessment opportunity, we explore to optimize ventilator management processes to reduce security risks by using the advanced quality management tools. Methods:Based on the ventilator maintenance statistical data in year 2012, we applied Pareto chart, Pareto curves and fishbone diagrams etc. quality management tools, and conducted PDCA cycle analysis on safety factors of ventilator clinical application. At the end, we summarized the results and provide improvements recommendations. Results:The cumulative proportions fell from 23.6%to 80%range, the human operator, compressor inlet;pipeline leaks and consumables management are a major are major factors. Through fishbone diagram analysis, we categorized them into 4 aspects:personnel, operations, equipment and supplies management. We optimized existing systems and processes from three areas:the device management, supplies management and training. By implementing these improvements plans, the security risk caused by supplies management was basically solved, the effect is very obvious. Conclusion:By using quality management tools, the safety problems during clinical application of ventilator can be reflected directly and clearly, and protect ventilator safe and stability to next level, so that it helps medical equipment management be more scientific, effective and normative.

OBJECTIVE:To study the antiulcer action of norfloxacin zinc(NF-Zn) METHODS:Acute and chronic gastric ulcer models were established in rats and the in vitro action of neutralizing hydrochloric acid and the MIC for Hp of NF-Zn were determined RESULTS:NF-Zn could inhibit the formation of acute gastric ulcer induced by ethanol,stress and salicylic acid in rats,accelerate the healing of chronic gastric ulcer produced by acetic acid,inhibit the secretion of gastric acid and increase the pH in gastric juice In vitro,NF-Zn could neutralize HCl and inhibit Hp with MIC50 of 0 5?g/ml CONCLUSION:The results suggest that the antiulcer action of NF-Zn may be related with its protection of the gastric mucosal barrier,neutralization of acid and inhibition of Hp

ObjectiveTo explore the correlation between butylphthalide and plasma brain-type creatine kinase isoenzyme (CK-BB),endothelin (ET),calcitonin gene related peptide (CGRP) in patients with acute cerebral infarction (ACI).MethodsSixty patients with ACI were divided into treatment group and control group with 30 cases each by random digits table method.Both groups received normal treatment continuously for 7 days,and butylphthalide of 200 mg was added to treatment group for 3 times per day.The levels of plasma CK-BB,ET and CGRP of two groups before and after treatment were measured and compared.ResultsThe levels of plasma CK-BB,ET of two groups both decreased significantly after treatment,but CGRP rose obviously.It showed significant differences before and after treatment of both groups (P <0.01 or < 0.05).The levels of plasma CK-BB,ET of treatment group after treatment were lower than those of control group in the same period [(216.48±36.95) U/L vs.(333.07±54.03) U/L,(83.33±26.48)ng/L vs.(98.46±31.46) ng/L,P < 0.05 ].The level of plasma CGRP of treatment group after treatment was significantly higher than that of control group in the same period [ (44.16±13.28 ) ng/L vs.(36.42±12.31 )ng/L,P < 0.05 ].ConclusionButylphthalide can reduce the plasma enzyme activity,balance ET and CGRP,extend the cerebral arteries to antagonize ET,improve cerebral ischemia and cerebral hypoxia,which can protect brain cells and endothelial cells.
