Objective:Through the analysis of the influence indicators of average hospitalization and comparison of differences of these indicators among different clinical departments in a hospital, to evaluate the medical quality and management level of the hospital and provide scientific reference for improving the hospital management efficiency and benefits.Methods:Gender, age and the type of medical insurance were analyzed using the chi square test. The length of hospital stay through 2009 to 2013 were analyzed using F test for patients of different insurance type and using t test for patients from different departments. All tests were completed using SPSS18.0.Results: The average hospital stay was decreasing year by year. Compared with the overall average length of stay, the patients who pay free were stay longer in hospital except for a small number of departments of internal medicine. Besides, the severe cases also prolonged the average length of stay in hospital.Conclusion: To effectively control the average length of stay, the Physicians Examination in Three Levels should be strictly implemented and the information management system should be used scientifically. Reasonable measures should be taken to solve the existing problems.

Objective To find out the brain function characters of visual information integration and visual working memory with attention deficit hyperactivity disorder (ADHD) children. Methods 1∶ 1 case-control study was used on the study. 45 ADHD children who met DSM-IV criteria were recruited as case group,45 normal children from primary school were chosen as control group. Two groups children received the test of contour-integration,positional noise, temporal order memory, pattern memory. Results The ADHD double eyes' contour integration ( ( 1.62 ± 0. 81 ), ( 1.69 ± 0.87 ) ) were significantly lower than the control group' ( (2.02 ± 1.10), ( 1.98 ±0.81 )). There was no significant difference of double eyes' positional noise between case group( (1.98 ±0.89 ), ( 2.20 ± 1.10 ) ) and the control group ( ( 2.20 ± 0. 97 ), ( 2.30 ± 0. 83 ) ). The temporal order memory,pattern memory ( ( 1.89 ± 1.30), ( 1.18 ± 0.44) ) showed significantly lower in case group(P< 0.05 ) than that in control group ( ( 2.98 ± 1.25 ), ( 1. 44 ± 0. 66) ). Conclusion Results indicate that children with ADHD have deficiency in visual perception and the ability of visual information integration, and have significantly deficiency in visual working memory and executive-function.

Jervine, a novel steroidal alkaloid from Veratrum nigrum L., exhibits both antitumor effect and potential toxicity. The aim of study was to characterize the pharmacokinetic behaviors and enterohepatic circu-lation of jervine in rats. A rapid and simple ultra-high performance liquid chromatography-tandem mass spectrometric method was developed and validated for quantification of jervine and alpinetin (internal standard) in rat plasma. After extraction from rat plasma by a simple protein-precipitation method, the analyte was separated on a C18 column (2.1 mm × 50 mm, 1.7μm) using water with 0.1%formic acid and acetonitrile as the mobile phase delivered at a flow rate of 0.4 mL/min. Jervine and alpinetin were determined in the positive mode with multiple reaction monitoring (MRM) of the ion transitions at m/z 426.3→108.8 and m/z 271.0→166.9, respectively. Molecular docking method was used to investigate the binding of jervine to p-glycoprotein and dehydroepiandrosterone sulfotransferase. The method was well validated within acceptance limits including specificity, matrix effect, recovery, precision, accuracy, and stability, and was successfully applied to the pharmacokinetic study of jervine after oral and intravenous administration to rats. Jervine presented a small volume of distribution, fast absorption, high oral bioavailability, and enterohepatic circulation. The enterohepatic circulation was first observed in veratrum alkaloids, and was further investigated by molecular docking studies, which was related to the binding of jervine to p-glycoprotein and dehydroepiandrosterone sulfotransferase. The pharmacokinetic properties and enterohepatic circulation of jervine in rats provided a significant basis for the drug-drug interaction and toxicity study in the future.
