1.Changes of Nitric Oxide and Endothelin Levels in Children with Lymphoma and Its Clinical Significance
Journal of Applied Clinical Pediatrics 2006;0(15):-
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.

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.

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 study the reproductive health status in adolescents underwent repeated abortion and their psychosocial behavioral status and to understand their demanding on the knowledge of contraception, so as to provide suggestions on post abortion care. Methods From July ,2007 to May,2008,400 unmarried adolescents who visited doctors and met the following criteria were recruited in the study:①Younger than 24 years old;②Had artificial abortion at least once;③Have been pregnant for 5-10 weeks and asked for artificial abortion. Data were collected through symptom checklist 90 (SCL-90)and anonymous reproductive health questionnaire. The situation of reproductive tract infections (RTIs) were detected through gynecological examination and laboratory tests.The data was analyzed by SPSS 11.5 statistical software. Results The mean age of the subjects was 21. 18 ±2. 46 years. The mean time of previous artificial abortion was 1.96 ± 1.44,with 52% of ≥2 times. Aged less than 20 years old at the first abortion,having sex more than 3 times per week,more than 2 sex partners,and history of painless abortion were associated with repeated abortion in unmarried adolescents. The SCL-90 scores showed that the subjects had higher score of depression, terror, psychiatric symptoms, somatization, interpersonal sensitivity,anxiety and hostility factors than normal population (P < 0. 05). Of the subjects ,34. 5% had history of RTIs, and the current prevalence of RTI was 59. 5% ,and 58. 5% with one kind of RTI and 36. 0% with two kinds of RTI. Of these RTI patients,33. 5% did not present any clinical symptoms. Abortion for more than twice,first sex intercourse occurred at age younger than 18,history of RTI,sex intercourse of more than 3 time per week,multiple sex partners,especially18,history of RTI,sex intercourse of more than 3 time per week,multiple sex partners,especiallyhaving multi sex partner at the same, and poor sex sanitation were risk factors of RTI. Conclusions There are various reproductive health problems among repeated abortion adolescents in mental and physical aspects, lack of knowledge on reproductive health and contraception is the main reason. Improving post-abortion services will be helpful to prevent repeated abortion in adolescents and protect their physical and mental health.
