Concentration of the trace organic contaminants in water by high adsorption capacity macroreticular resins, have been introduced to physical, chemical and biological analysis of organic compounds from surface water, underground water, tap water and different kinds of wastewaters, and runoff water. This review summarized the techniques and conditions for the application of macroreticular resins to concentrate the organic compounds in water, including purification of resin, column preparation, solvents extraction and elution, concentration of eluate and resin regeneration. It is suggested that it is necessary to set the technique criteria for the application of macroreticular resins.

OBJECTIVETo study the MRI features of proximal femur bone marrow edema syndrome for further improve the understanding of the disease.

METHODSMRI imaging of 10 patients with proximal femur bone marrow edema syndrome was retrospectively reviewed,including 6 males and 4 females with an average age of 41.5 years old ranging from 36 to 57. The courses of diseases ranged from 1 week to 3 months. Among them, 9 cases had clinical manifestations of sudden hip pain, 7 cases had limited ability of walking and hip movement;all patients had no obvious injury history, non of the female patients was pregnant. All patients were followed up from 3 to 12 months, the following-up were topped after MRI when the symptoms disappeared for 3 months.

RESULTSThe MRI demonstrated diffuse bone marrow edema involving the femoral head, neck and the inter-trochanteric region, 13 hips of 10 patients with bone marrow edema included 6 cases in grade 1, 5 cases in grade 2,2 cases in grade 3; 9 hips with hip hydrarthrosis included 6 hips in grade I ,1 hip in grade II, 2 hips in grade III. After treatment for 3 to 12 months the hip symptoms of the patients disappeared and MRI images were normal.

CONCLUSIONMRI is useful in defining the location and extent of proximal femur bone marrow edema syndrome.

Information ethics brings new issues and reflections on medical information services under network environment.By analyzing relevant issues including equally and freely acquiring medical information service,network knowledge property,network privacy protection,and information monopoly,this article explores the ethical construction of medical information staff.

It is critical to assess the development and injury of brain function in premature infants in early stage.Currently,brain development and brain injury are evaluated by many ways and mainly by kinds of imaging and behavioral neurological assessment.The integrated application of these examination methods have been explored for years.The combination of resting-state functional magnetic resonance imaging and electroencephalography has prominent advantages,because they do not need to perform specific tasks,and they are noninvasive and non-toxic for preterm infants.Based on the support vetor machine learning of artificial intelligence technology,the typical characteristics of 2 multimodal data can be integrated and a multimodal assessment system which automatically monitor and predict premature infants' brain function development and injury can be established.

Objective To study the safety of Plumula nelumbinis microcapsules and its anti-arrhythmic effect.Methods Acute toxicity test in mice,arrhythmia mice models induced by chloroform and arrhythmia rats models induced by barium chloride(BaCl2)were adopted.Results The maximum tolerance dose for mice was 16.0 g/kg body weight.The microcapsule decreased the incidence of chloroform-induced ventricular fibrillation in mice significantly(P 0.05,compared with the blank control group).Conclusion The preliminary results show that Plumula nelumbinis microcapsule is safe,and exerts anti-arrhythmic effect against experimental arrhythmia.

Determination of SCE frequency, chromosomal aberration and micronucleus rate of cultured peripheral lymphocytes of 38 miners who worked in the well, and 40 non-miners who worked outside the well in Dachang Area and 27 other workers who didn't work and live there (as control group) was carried out. The result showed that the miners had higher SCE incidence and chromosomal aberration rate. The nonmining workers and the control group had much lower rates. There was a significant difference between the miners and non-miners or control group, but no statistically differences were found between the non-miners and the control group. Micronucleus rate among the miners, the non-miners and the control group were all the same level statistically. We proposed that some toxic substances in the Dachang Tin Mine might be respousible for the genetic damages in the miners. We suggested that a combined assay of SCE with chromosomal aberration or micronucleus might be a good screening method for the high risk population such as the miners in Dachang Tin Mine.

OBJECTIVE:To evaluate the utilization status and the developmental trend of non-steroidal anti-inflammatory drugs(NSAIDs) in our city.METHODS:NSAIDs used in two hospitals in Anhui Tongling city during 2004～2006 were analyzed statistically in respect of drug varieties,DDDs and consumption sum.RESULTS:The DDDs of NSAIDs increased,up 7.07% year on year. The consumption of NSAIDs increased by 4.15% in 2005,but decreased by 4.94% in 2006.New type NSAIDs had a great increase in consumption sum.CONCLUSION:The utilization structure of NSAIDs in our city is expected to remain stable in the coming several years,but great attention should be paid to the ADR of NSAIDs.

Medical diagnostics is an important subject using basic theory,basic knowledge and basic skills in the diagnosis of the disease.However,the traditional teaching of physical diagnosis only provides the limited clinical operations based on the books,and lacks detailed and comprehensive knowledge of important theories of practical application,while the multi-media in the samples on the application of diagnostics can be a good solution to this problem.
