2.Effective evaluation of brucellosis related risk behaviors of occupation groups and the effect of health education
Chinese Journal of Endemiology 2011;30(2):208-210
Objective To find out demography characteristic and risk behaviors of occupation groups and to evaluate the effect of health education. Methods A baseline survey was conducted among occupation groups in the western part of Liaoning province by stratified random cluster sampling. Health education started to intervene in occupation groups in Linghai city of Liaoning province. An investigation of brucellosis related behaviors was carried out before and after a health education among occupation groups. Other occupational groups were as the control group. The research on high-risk behaviors of occupation groups was in the following eight aspects: protection taken when contact with abortion livestock, timely slaughter and burying deeply of sick animals, not selling sick animals do not eat dead meat, nor drink raw milk, do not eat raw meat, and immunity of livestock. Results Before the intervention, a total of 916 objects, of which intervention group 499 and control group 417 were investigated. The high-risk behaviors of brucellosis were not significantly different between the two groups[70.9% (354/499), 64.3%(321/499 ), 53.8% (268/499), 92.2% (460/499), 82.2% (410/499 ), 87.5% (437/499), 93.6% (467/499), 56.2%(280/499) in intervention group, 68.8% (287/417), 59.2% (247/417 ), 54.7% (228/417), 89.2% (372/417 ), 85.6%(360/417) ,885%(369/417),94.0%(392/417),55.9%(233/417) in control group, all P > 0.05]. After the intervention,a total of 908 survey objects, of which intervention group 499 and control group 409, were investigated. The above eight aspects of high-risk behaviors in the intervention group were 85.4% (426/499),79.0% (394/499),69.9%(349/499),96.4%(481/499),943%(471/499),94.9%(474/499),94.0%(469/499), 99.4%(496/499), respectively; in the control 66.8% (273/409),57.3% (234/409),50.1% (205/409),85.3% (349/409),88.8% (363/409),89.5%(366/409) ,90.1% (369/409), and 57.2% (234/409), respectively. Between the two groups, the difference was statistically significant (x2 = 43.991,49.833,37.111,35.032,9.537,9.826,4.485,253.808, all P < 0.05 ). The above seven aspects of high-risk behaviors except do not eat raw dairy at the beginning of intervention were compared with those of after the intervention, the differences were statistically significant (x2 = 30.426,26.284,27.854,7.364,36.027,17.238,9270.286, all P < 0.05). Conclusions Health education intervention can significantly improve the behavior change rate of occupational groups at high risk of brucellosis, and the education intervention is worthwhile to communicate and promote.

Objetive To elucidate the mechanism of antibiotic resistance of Pseudomonas aeruginosa(P.a.) in an effort to provide a basis in clinical combined use of antibiotics against P.a.infection in clinical settings.Methods All P.a.strains were isolated by routine procedures and identified with VITEK-2 automatic bacterial identification console.The minimum inhibitory concentration(MIC) was detected using dilution method on agar plate following the instruction of CLSI.Results Ninety-two strains of P.a.were isolated from clinical infection specimens,most of them were obtained from respiratory tract(88.04%).Of the 92 strains,45(48.91%) were metallo-?-lactmases positive,and 25(27.17%) were AmpC positive.When treated with a combination of meropenem and imipenem,MIC≥1 was found in 17 strains(18.48%).The bacteriostatic rate of polymixin B and meropenem was 95.65% and 80.43%,respectively,that of amikaein,piperacillin/tazohaetam(PIT) and imipenem was 48.91%-71.74%,and that of cefoperazone/sulbactam(SUP) was 36.96%.The synergistic action of PIT,and SUP with amikacin was 60.87% and 58.70%,respectively,and that of PIT,SUP with minocycline were 44.57% and 43.48%,and of PIT,SUP with PLB were 28.26% and 7.61%,respectively.Conclusions P.a.strains in this study are mainly isolated from respiratory tract infection specimens.Multiple drug-resistant mechanisms are involved in the drug resistance of P.a.Enzyme inhibitors,such as PIT or SUP,with amikacin or polymixin B should be first selected for clinical treatment of P.a.caused infection.Meanwhile,antibiotics should be rationally administered in accordance with the seriousness of disease,and with the drug-resistant phenotype of the isolated strains.

In order to have a better basic research of needle sticking, reports regarding basic research of needle sticking in recent years are arranged and summarized, including the concepts of needle sticking, the history origin, manipulation methods, precautions and selection requirements of needles. In the meanwhile, the reinforcing and reducing manipulation in sticking of the needle is preliminarily analyzed, and based on analysis of ancient records, three hypotheses are proposed: (1) needle sticking partly belongs to reinforcing method; (2) needle sticking partly belongs to reducing method; (3) needle sticking can perform reinforcing and reducing effects according to different manipulations. It is also believed that the needle sticking in modern clinical research is mostly used for reducing effects. However reinforcing and reducing manipulation in sticking of the needle still lacks of the support from ancient literature theory and modern clinical application, which needs to be improved.

Objective To investigate the clinical value of the intervertebral disc morphous in patients with thoracolumbar vertebral compression fracture. Methods The MRI, X-ray and CT data of 75 patients with thoracolumbar vertebral compression fracture were retrospectively analyzed. The intervertebral disc damage degree was observed, and its correlation with vertebral fracture degree and endplate damage degree was studied. The vertebral body leading edge height, intervertebral space height and back convex Cobb angle in patients with different intervertebral disc damage degree were measured. Results The intervertebral disc damage degree height was positively correlated with endplate damage degree (P<0.01), and the intervertebral disc damage degree was positively correlated with fracture degree (P<0.01). With the increase of the intervertebral disc damage degree in patients with Ⅰ - Ⅳtype intervertebral disc damage, the vertebral body leading edge height and intervertebral space height gradually became smaller: (0.68 ± 0.05), (0.61 ± 0.03), (0.58 ± 0.03), (0.42 ± 0.05) mm, and (0.31 ± 0.06), (0.29 ± 0.03), (0.24 ± 0.06), (0.22 ± 0.02) mm, and there were statistical differences (P<0.05). There was no statistical difference in back convex Cobb angle in patients with different intervertebral disc damage degree (P>0.05). Conclusions It is more important to observe the morphological changes of the intervertebral disc in patients with thoracolumbar vertebral compression fracture, and the damage degree is closely related with the vertebral fracture degree and endplate damage degree.
