DICOM is a standard for data format and transmission of digital medical image. DICOM Data Set is a binary data stream using DICOM encoding rule. DICOM Nesting Data Set is a kind of complex Data Set with a tree structure, and is widely used in DICOM services and encoding of DICOM files for its special structure. In this article, the functions and encoding rule of Data Set and Nesting Data Set in DICOM format are presented, and the way of parsing and organizing of them is put forward. The realization method and practical application are also discussed.

Objective To investigate the protective effect of Edaravone on dopamine transporter in rat models of Parkinson disease.Methods Rat models of Parkinson disease were induced by injection 6-OHDA into right medial forebrain bundle. Edaravone at different doses (3.0 mg/kg, 1.0 mg/kg or 0.3 mg/kg) was injected intraperitoneally twice daily for two weeks. The same dose of normal saline was injected in the control group. One week after the treatment, the ?-radiation of rat bilateral striatum, cerebral cortex and cerebella cortex of each group was measured by a ?-counter and the brain tissue ID value was calculated.Results There was a significant difference of the radiation count in right striatum between the large dose group (0.47?0.06) ,medium doss group(0.37?0.02)and the control group (0.25?0.01)( P

Objective To examine the effect of treatment with reduced glutathione(GSH) in 6-OHDA induced rat models of Parkinson's disease(PD).Methods 35 SD rats were received injection of 6-OHDA by medial forebrain bundle to make lateral PD models.According to rotation test induced by Apomorphine 6 weeks later,the model rats were divided into partial PD group and total PD group.Each group was further divided into reduced glutathione hormone(GSH) sub-group and control sub-group randomly.The sub-groups were treated intraperitoneally with GSH or normai saline every day for 4 weeks,respectively.The functional outcome of each group was measured using the Apomorphine induced rotation test at 2,4,6 and 8 weeks after treatment.Results Successful PD models were made in 27 of 35 rats,which included 13 partial PD models and 14 total PD models.The numbers of rotation per minute induced by Apomorphine at 4,6 and 8 weeks after treatment with GSH in partial PD group were significantly lower than that before treatment and in the control sub-group((P

The content of ATP, ADP, AMP, sodium phosphate and sodium pyrophosphate were determined by 31P NMR, the linear range of ATP, ADP and AMP were found to be 0.004-0.080 mol x L(-1), sodium phosphate and sodium pyrophosphate were 0.005-0.100 mol x L(-1). The RSD were 0.40%-1.30%, the recovery were 96.9% - 105.2%. The method has been applied to the determination of ATP injection. The impurities of ATP injection were ADP and sodium phosphate. The content of ATP is in line with the requirement of the pharmacopoeia. The results indicated that the method is of good reproducibility, high accuracy, rapid and simple operation, without pretreatment and interference of other elements, 31P NMR is a new and reliable method of analyzing ATP, ADP, AMP and phosphate.

Clinic demonstration is the important part of medical education.There are more and more medical students with enlarged university enrolment in recently year.However,the patients for demonstration are relatively fewer.In this condition,we make the best of the available resources to demonstrate clinic pediatrics by teaching at bedside;displaying video products,using human analogue and case record and role playing,thus ensuring the effect of clinic pediatric teaching.

Objective To observe the hemodynamic changes during operation of piggyback liver transplantation.Methods The Swan-Ganz catheter was inserted and the parameters of hemodynamics were analyzes in 36 patients with chronic hepatic diseases following piggyback liver transplantation. The cardiac output(CO)and pulmonary arterial pressure(PAP)were measured.Results CO and PAP were decreased significantly in the anhepatic phase(P

Objective To compare the clinical effects of ROI-C self-locking fusion cage and common cage+titanium plate fixation on treatment of multi-segment anterior decompression and fusion for cervical spondylotic myelopathy.Methods From March 2010 to September 2013,92 patients with multi-segment cervical spondylotic myelopathy were treated with anterior decompression and fusion.52 patients were treated with common cage plus titanium plate fixation,while 40 patients were treated with ROI-C self-locking fusion cage.Clinic data including clinical preoperative condition,operation time,intraoperative blood loss,intervertebral space height,Cobb angle of cervical spine,bone graft fusion rate,complications,and JOA score and VAS score were compared.Results Follow-up visit was conducted for all cases,with the time of 12-48 months (22 months on the average).The neurologic symptoms of patients in two groups were relieved obviously after postoperative 1 week,including chest and abdomen constriction feeling,finger pain,finger and lower limb activities.Intervertebral space height of cage +titanium plate group and ROI-C fusion cage group increased to 79.06±6.67 mm and 78.80±6.85 mm respectively after postoperative 3 months from preoperative 47.15±6.96 mm and 46.95±7.14 mm;the Cobb angle increased to 9.29°±12.90° and 8.57°±13.00° respectively after postoperative 3 months from preoperative 4.27°±11.15° and 2.80°±10.81°.In ROI-C group,the operation time,intraoperative blood loss and postoperative complications were significantly lower than those in cage+titanium plate group.The differences of two groups have statistical significance.In the last follow-up visit,JOA score of ROI-C group increased to 15.15±0.91 from preoperative 9.32±1.74,with the improvement rate of 75.82％±13.28％;JOA score of cage + titanium plate group increased to 15.29± 1.07 from preoperative 9.11 ± 1.23,with the improvement rate of 77.91％± 14.14％.The differences of two groups in the improvement rate have no statistical significance.Conclusion Curative effects of ROI-C self-locking fusion cage and common cage+titanium plate fixation on treatment of muhi-segment anterior decompression and fusion for cervical spondylotic myelopathy are similar,while ROI-C self-locking fusion cage has such advantages as short operation time,less blood loss,little injury and low complication incidence.

OBJECTIVE To explore the distribution of 16S rRNA methylase and aminoglycoside modifying enzymes in continuous isolates of Pseudomonas aeruginosa(PAE).METHODS The antibiotics susceptibility was tested by K-B method,the 16S rRNA methylase(rmtB) and aminoglycoside modifying enzymes were detected by polymerase chain reaction(PCR),the positive genes were amplified and sequenced by PCR fluorescence spectrophotometry.RESULTS Among 20 strains of PAE,the 16S rRNA methylase and 5 kinds of aminoglycoside modifying enzymes had been detected.The 5 kinds of aminoglycoside modifying enzymes were aac(3)-Ⅱ,aac(6′)-Ⅰb,aac(6′)-Ⅱ,ant(3″)-Ⅰ and ant(2″)-Ⅰ,respectively.And more,the rmtB in the first and third strains was sequenced,and translated into amino acid,and the translated amino acid sequence was compared with GenBank,suggesting there be different amino acid sequence.This was confirmed as two new subtypes.CONCLUSIONS Resistant to antibiotics PAE in our hospital is mainly related to 16S rRNA methylase and 5 aminoglycoside modifying enzymes,and 2 new subtypes of 16S rRNA methylase are discovered.
