Objective To investigate the changes and clinical signficance of nitric oxide(NO) and endothelin(ET) in children with lymphoma.Methods NO and ET of 39 cases with lymphoma and 33 normal controls were examined by using nitrose reductase method and RIA method.Results Compered to normal controls,NO and ET were higher in children with lymphoma;smilar to normal controls in complete remission(CR) and partial remission(PR);relapse cases were higher than remission.Conclusions NO and ET could have relation to lymphoma in children,testing the changes of NO and ET have signficanc to the assistant diagnosis,observeing effect and judging prognosis.

Based on the analysis on the most common type of scientific research and clinical application of stem cells, including embryonic stem cells , hematopoietic stem cells and mesenchymal stem cells as the breakthrough point, discusses common phenomenon and problems of ethics , scientific research and clinical study the moral life science century new topic, hope scientists, physicians, ethicists, caused by the administrative departments for pub-lic health thought , promote stem cells healthy and steady development .

ObjectiveTo observe changes of calcitonin gene related peptide (CGRP) and aetylcholinesterase (AChE) in motor endplate (MEP) after complete spinal cord injury (SCI) in the rat.MethodsSCI model of Wistar rats were established by transecting T10 spinal cord completely. The venters of the tibial anterior muscle were taken at 1, 2, 4 and 8 weeks postoperatively to carry out the experiment.The changes of CGRP and AChE in the MEP were investigated with immunohistochemical test.ResultsAfter complete SCI, the quantity and distribution of CGRP decreased in MEP of 1-week sample, and the changes of AChE were observed until 4-week sample, and although the staining was light and sparse, CGRP and AChE existed in MEP during 2 months postoperatively.ConclusionThere is degeneration of MEP in skeletal muscle after upper motor neuron injury; CGRP and AChE are related to the degeneration of MEP; CGRP test can show the changes of MEP earlier.

ObjectiveTo explore the diagnostic value of 16-slices CT in urinary calculus. Methods25 cases of suspected urinary calculus were examined by 16-slices CT and some of these images were reconstructed with MPR. ResultsIn the 25 casces CT found 21cases of urinary calculus,among them kidney calculus 22 cases,urinary tract calculus 13 cases.In 5 of 21 cases,urinary calculus were not found with US.In all 6 cases urinary calculus were not detected by KUB and/or IVP. Conclusion16-slices CT was a valuable method in diagnosing urinary calculus.

Nowadays, LAN can't meet the requirements of field communication, and WLAN is playing more and more important role for its strong transmission ability and high mobility. This paper introduces the application of WLAN to filed medicine.

We proposed a research of a heart sound envelope extraction system in this paper. The system was implemented on LabVIEW based on the Hilbert-Huang transform (HHT). We firstly used the sound card to collect the heart sound, and then implemented the complete system program of signal acquisition, pretreatment and envelope extraction on LabVIEW based on the theory of HHT. Finally, we used a case to prove that the system could collect heart sound, preprocess and extract the envelope easily. The system was better to retain and show the characteristics of heart sound envelope, and its program and methods were important to other researches, such as those on the vibration and voice, etc.

Objective:To compare the drug release of nifedipine sustained-release tablets from four manufacturers to evaluate the intrinsic quality. Methods:The drug release rate was determined by UV respectively with pH 1. 2 HCl solution, pH 4. 0 sodium ace-tate buffer, pH 6. 8 phosphate buffer and water as the dissolution medium. The dissolution curves were compared by f2 factor. Results:The drug release rate of nifedipine sustained-release tablets from the four manufacturers all met quality standard of our country, al-though the dissolution curves in the different dissolution medium was various. Conclusion:There are differences in intrinsic quality a-mong the nifedipine sustained-release tablets from the four manufacturers. The dissolution examination standard should be improved fur-ther.
