KAP Investigation and Ethical Countermeasures for Uv Occupational Injuries in Xi′an Physical Education Teachers / 中国医学伦理学

Objective: To investigate and analyze the KAP situation for Uv occupational injuries in Xi′an physical education teachers and provide scientific basis for the protection .Methods:Scale and questionnaire are used to survey 1200 people , using a questionnaire method to Xi′an sports teachers′occupational injuries is ultravio-let ray KAP investigation.Results:Respondents had a history of sunburn (21.5%), worked as a certified check the skin accounts for 5.1%;Think long-term outdoor ultraviolet harm to the skin (34.1%), 58.9%take protec-tive measures, can correct understanding on the Uv 3.2%; The purpose of protective measures , 43.9% of re-spondents take measures the purpose is to prevent tanning rather than prevent sunburn .Conclusions:Physical edu-cation teachers as a special outdoor work group , the overall Uv occupational injuries protection knowledge was low , from the perspective of the biopsychosocial medical model should be based on the principle of health ethics , it should strengthen the propaganda of knowledge of Uv occupational injury protection , and actively take appropriate intervention measures .

Analysis of chromosome regions 8q11.1-q13.3, 1q32-q34.3 and 14q31.1-q13.3 in a Chinese family with congenital preauricular fistula / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To identify the candidate chromosomal region for congenital preauricular fistula (CPF) through analysis of an affected Chinese family.</p><p><b>METHODS</b>Conventional linkage analysis using short tandem repeats (STR) markers was performed to investigate three chromosomal regions 8q11.1-q13.3, 1q32-q34.3 and 14q31.1-q31.3.</p><p><b>RESULTS</b>None of 16 STRs could attain a LOD score of more than -2.0 (theta=0). Therefore, the three regions were all excluded as the candidate region for the disease.</p><p><b>CONCLUSION</b>CPF features high genetic heterogeneity. The family may have a causative gene elsewhere. Whole-genome-based study is needed to identify its genetic etiology.</p>

N-Acetylcysteine attenuates methamphetamine induced neurotoxicity in rat striatum / 中国药理学通报

Aim To explore the effects of N-acetylcysteine(NAC) on methamphetamine(METH) induced neurotoxicity of striatum in rat model and its mechanism.Methods NAC was administrated(ip) 30 min prior to METH injection to produce toxic rat model.Dihydrodichlorofluorescein diacetate was used to detect the level of reactive oxygen species(ROS),high performance liquid chromatography for the concentration of Dopamine(DA),meanwhile,TUNEL method was used to observe the neuron apoptosis.Results Pretreatment with NAC could decrease the level of ROS in rat striatum,prevent the loss of DA and decrease the TUNEL-positive neurons.Conclusion NAC could attenuate methamphetamine-induced neurotoxicity in rat striatum by blocking ROS production.

Clinical analysis of 31 cases of intra-abdominal hernia / 第三军医大学学报

Objective To analyze the causes and the scheme of diagnosis and treatment of intra abdominal hernia. Methods Clinical data from 31 cases of intra abdominal hernia from 1977 to 2001 were analyzed retrospectively. Among the patients were 26 male and 5 female, and 4, 6, 19, and 2 patients were at the age range of 16 25, 26 40, 41 55, and over 56 years old, respectively. Results The causes of congenital intra abdominal hernia were related to malrotation of intestine and abnormality of intestine fixation during embryogenesis, to erroneous juncture of visceral layer peritoneum with parietal peritoneum, and to partial degeneration and weakness of mesentery. The causes of acquired intra abdominal hernia were related to operation or trauma. Conclusion As to patients with intermittence or episode of stomachache, touched painful sausage like mass, intestinal obstruction by X ray, and displacement of aortic arch of small intestines shown by selective arteriography, diagnosis of intra abdominal hernia and immediate operation should be considered. When reduction of the twisted intestines and repair of the hernial neck or hiatus are performed, important blood vessels such as the superior mesenteric arteries should not be injured.
