Inflammatory bowel disease (IBD) mainly includes Crohn′s disease (CD) and ulcerative colitis (UC) . The imaging diagnosis of CD is difficult because of its complex disease and varied imaging manifestations. Standardizations of imaging techniques and reports are helpful to improve the imaging diagnosis level of CD. This article aims to provide guideline for the imaging technique selection, scanning scheme formulation, imaging features interpretation and imaging report writing of CD in China.

OBJECTIVE:To promote the working performace of automatic medicine packing machine in our hospital. METH-ODS:Combined with the problems we met in the use of the automatic medicine packing machine,the reconstructions of software functions,such as drug inventory management,drug identification,specific drug sub-package and document printing of non-pack-age drug,were introduced. Related indicators were compared before and after reconstruction. RESULTS:After the software recon-struction,compared with 2012,loss events of expire drug due to poor sales fell by 70% in 2013;drug dispensing errors related to medicine packing machine dropped by 1/2;the time of drug checking shortened by 1/5. CONCLUSIONS:The software program re-construction of automatic medicine packing machine can improve the work efficiency of pharmacy and the accuracy of drug dispens-ing,further guarantee the quality and safety of drugs,and meet the practical demand of our hospital.

OBJECTIVETo analyze the relationship between metabolites of polycyclic aromatic hydrocarbons (PAHs) and serum uric acid levels in coke oven workers and to provide new clues to the pathogenic mechanism of PAHs.

METHODSA total of 1302 coke oven workers were divided into four groups, namely control group and low-, intermediate-, and high-dose exposure groups. The concentrations of ambient PAHs at each workplace were determined by high-performance liquid chromatography. The detailed information on the occupational history and health of workers was collected by questionnaire survey and physical examination, and so were their blood and urine samples. Serum uric acid and creatinine levels were measured using a Hitachi 7020 automatic biochemical analyzer. Ten urinary PAH metabolites were detected by gas chromatography-mass spectrometry.

RESULTSSerum uric acid levels were the highest in the high-dose exposure group, followed by the intermediate- and low-dose exposure groups, and were the lowest in the control group. There were significant correlations between serum uric acid levels and the quartiles of 1-hydroxynaphthalene and 1-hydroxyphenanthrene (P < 0.05). After adjustment for PAH metabolite-related relationship, only urinary 1-hydroxyphenanthrene was significantly correlated with serum uric acid levels (P = 0.001). After adjustment for confounding factors and using the 1st quartile of 1-hydroxyphenanthrene as a reference, the odds ratio for hyperuricemia in subjects with the 2nd, 3rd, and 4th quartiles of 1-hydroxyphenanthrene were 1.55, 1.57, and 2.35, respectively.

CONCLUSIONUrinary 1-hydroxyphenanthrene is associated with a dose-response increase in serum uric acid levels in coke oven workers, and exposure to phenanthrene in PAHs may be a risk factor for hyperuricemia.
