BACKGROUND: To determine the non-or collapsed osteonecrosis of the femoral head (ONFH) and degree of collapse, can help surgeons design reasonable treatment strategy for patients with ONFH. In China, articular cartilage collapse less than or greater than 2 mm, is a basis for choosing palliative surgery or hip replacement. However, the measurement of collapsed ONFH before replacement has not yet been confirmed. OBJECTIVE: To predict the collapse of femoral head before replacement by CT and X-ray examinations, and to compare with the intraoperative excised femoral head specimens.METHODS: This was a single-center, open-label and diagnostic trial, which was finished at the Third Hospital of Hebei Medical University, Shijiazhuang, Hebei Province, China. Eighty-six patients with unilateral ONFH undergoing total hip replacement were recruited, and allocated into three groups, such as X-ray, CT and specimen groups. The X-ray group underwent X-ray examination at anteroposterior pelvic (bilateral hips) at 1 week before surgery, the CT group received CT scan at bilateral hips at 1 week before surgery, and the specimen group was subjected to the removal of affected femoral head, and then directly measured using ruler and vernier caliper. Primary outcome was the sensitivity of thesethree methods for measuring collapsed femoral head. Secondary outcomes were the specificity, positive predictive value,negative predictive value, positive likelihood ratio, and negative likelihood ratio of these three methods for the diagnosisof collapsed femoral head and the diagnostic accuracy; the diagnostic consistence of CT and X-ray examinations; the height of the lateral, middle and external femoral head measured by three methods. The study was approved by the Ethics Committee of the Third Hospital of Hebei Medical University, China, and will be performed in accordance with the guidelines of the Declaration of Helsinki, formulated by the World Medical Association. Written informed consent will be obtained from all participants prior to the trial. DISCUSSION: In this study, the height of femoral head was measured and analyzed in all-dimensional and multi-anglemanner based on intraoperative removed specimens, so as to make an accurate prediction for collapsed femoral head, thus providing imaging reference for surgeons prior to choosing an appropriate operative scheme

OBJECTIVE:To explore the effects of PDCA(plan,do,check,action)cycle theory in the ADR monitoring of our hospital. METHODS:The problems of ADR monitoring in our hospital in 2012 were analyzed and intervened by PDCA cycle. The effects of PDCA cycle were evaluated 1 year later. RESULTS:After implementation of PDCA cycle,we had improved the manage-ment system,brought ADR monitoring into the appraisal of clinical pharmacists,established the networking platform of ADR report-ing,strengthened the training of physicians and nurses,the publicty of ADR information and ADR monitoring of important medi-cine. The number of ADR reports increased by 18.37% in 2013,the proportion of new and serious ADR reports obviously in-creased(increasing from 22.28% to 38.42%);in terms of ADR reporting source,the ADR reporting in wards obviously increased (increasing from 8.16% to 43.84%). The proportion of ADR induced by antibiotics or TCM preparation decreased significantly(re-spetively decreasing from 54.52% to 43.84% and 23.03% to 13.30%);in term of ADR clinical manifestations,the proportion of skin and its appendants involved decreased significantly (decreasing from 53.64% to 39.41%). CONCLUSIONS:The application of PDCA cycle obviously improves the management of ADR monitoring in our hospital.

Neomangiferin, a natural C-glucosyl xanthone, has recently received a great deal of attention due to its multiple biological activities. In this study, a rapid and sensitive ultra-high performance liquid chroma-tography tandem mass spectrometry (UHPLC–MS/MS) method for the quantification of neomangiferin in rat plasma was developed. Using chloramphenicol as an internal standard (IS), plasma samples were subjected to a direct protein precipitation process using methanol (containing 0.05% formic acid). Quan-tification was performed by multiple reactions monitoring (MRM) method, with the transitions of the parent ions to the product ions of m/z 583.1-330.9 for NG and m/z 321.1-151.9 for IS. The assay was shown to be linear over the range of 0.2–400 ng/mL, with a lower limit of quantification of 0.2 ng/mL. Mean recovery of neomangiferin in plasma was in the range of 97.76%–101.94%. Relative standard deviations (RSDs) of intra-day and inter-day precision were both o 10%. The accuracy of the method ranged from 94.20%to 108.72%. This method was successfully applied to pharmacokinetic study of neomangiferin after intravenous (2 mg/kg) and intragastric (10 mg/kg) administration for the first time. The oral absolute bioavailability of neomangiferin was estimated to be 0.53%7 0.08%with an elimination half-life (t1/2) value of 2.74 7 0.92 h, indicating its poor absorption and/or strong metabolism in vivo.
