ABSTRACT
OBJECTIVE： To investigate the current situation of medication safety in 24 public medical institutions（referred to as “hospital”） from Linyi city and the differences in medication safety between urban and rural areas. METHODS： ISMP self-assessment scale [including 10 key elements （Ⅰ-Ⅹ，such as “Ⅰ patient’s information” “Ⅱ drug information”）， 20 key characteristics and 270 evaluation projects] developed by Institute of Safe Medication Practices was used to investigate 24 hospitals in Linyi city. The implementation rates of 10 key elements in urban and rural hospitals were analyzed statistically， and the top 10 evaluation projects were listed for the key elements with the lowest implementation rate. The key elements and top 10 evaluation projects with the largest difference in the implementation rate were compared between urban and rural hospitals. Radar maps were used for comparison and analysis intuitively. RESULTS： A total of 24 hospitals were surveyed， including 12 in urban and 12 in rural areas； there were significant differences in the implementation rate of 10 key factors among 24 hospitals； the elements with the highest implementation rate were “Ⅶ environmental factors， workflow and staffing pattern”（56.55％）；the elements with the lowest implementation rate was “Ⅱ drug information” （26.77％）. Among 33 evaluation projects of “Ⅱ drug information”， the implementation rate of No. 36 project （12.50％， related to opioids） was the lowest. Among the implementation rates of 10 key elements in 12 urban hospitals and 12 rural hospitals， the key elements with the greatest difference was “Ⅳ drug label， packaging and naming” （differing by 44.44％，59.72％ vs. 15.28％）； Among“Ⅸ patient education”evaluation project with the greatest gap， there was the greatest difference in No. 199 project （related to patients’ active participation in medication， 58.33％ in urban， 4.17％ in rural）. CONCLUSIONS： The results of medication safety investigation in 24 hospitals from Linyi city show that all the item in each hospital needs to be improved expecially in the implementation of “Ⅱ drug information”. Rural hospitals should strengthen medication education for patients.
ABSTRACT
There are some common analysis challenges in the hormone detection in agriculture science, including matrix interference, complicated sample preparation, poor reproducibility, trace analyte content. An automated on-line SPE and innovative fast polarity switch analysis method employing dual-gradient liquid chromatography ( DGLC ) coupled with tandem mass spectrometry ( DGLC-MS/MS ) was established and validated for the simultaneous determination of gibberellic acid ( GA3 ) , indole acetic acid ( IAA ) , zeatin ( ZT) and abscisic acid ( ABA) in the soybean plant ( leaf, grain and pod) . The method was applied in the actual sample detection successfully. In order to acquire higher sensitivity, recovery, stability and precision, some conditions including SPE column, analytical column, mobile phase, additive etc were optimized according to the selection and retain of hormone. Beans were cryogenically grinded by liquid nitrogen, extracted by 80% methanol, certrifugatel and dilluted with water, and then injected directly. Samples were transported and gradient eluted on the analytical column Acclaim PA2 by 0 . 1% formic acid in water and methanol, after retaining and separation on the SPE column Hypersep Retain AX. All analytes were detected in selection reaction monitoring ( SRM) mode in both positive and negative channels. The quantification was based on linear regression. The linear ranges of GA3, IAA and ZT were 0. 1-50 μg/L with the LOQ of 0. 0002 μg/g, and the linear of ABA was 0. 5-50 μg/L with the LOQ of 0. 0010μg/g. The recoveries of four kinds of plants hormones were 76 . 1%-93 . 5%, and RSDs were 0 . 82%-6 . 02% at low ( 0 . 8 μg/L ) , medium (4. 0μg/L) and high (40μg/L). The results noted that the content of ABA in seeds was apparently higher than others. This method could be used for the rapid and accurate detection of hormone in different parts of soya beans.
