Journal of Chongqing Medical University 2007;0(08):-
Objective:To investigate the expression and postmortem stability of HSP70 in hippocampus of hemorrhagic shock rat.Methods:105 healthy SD rats were randomly divided into 5 groups:normal group,sham operation group,hemorrhagic shock group,traumatic control group and postmortem stability group.In hemorrhagic shock group and postmortem stability group,rats were submitted by controlled bleeding,with the mean arterial pressure kept around 40mmHg.And in traumatic group,brain contusion was induced by piston impact.After that,the regulation of HSP70 expression in hippocampus of each group was detected by immunohistochemistry technique,and evaluated with image analysis technique and statistic system.Results:One hour after hemorrhagic shock,HSP70 expression in hippocampus was significantly higher in each shock subgroups compared with that in normal group and sham group(P0.05).Conclusion:HSP70 is specifically expressed in hippocampus of hemorrhagic shock rat,and showed nice postmortem stability under the environment of -20℃.

OBJECTIVE:To optimize kind of safe and effective iodophor thinner.METHODS:Iodophor solutions in several different solvents were made and diluted 5,10 and 20 times,respectively.Then their microbicidal potentials on 3 standard strains were monitored.RESULTS:The standard strains were all killed within 5 min by iodophor solution in normal sodium or by low multiple diluted iodophor solution in distilled water;however,there were a few Escherichia coli and Pseudomonas aeruginosa still alive within 5 min in high multiple diluted iodophor solution in distilled water.Iodophor solution in tap water failed to kill all the standard strains,especially the Pseudomonas aeruginosa.CONCLUSION:Normal saline solution and distilled water have been proved to be the ideal iodophor thinners.

Objectives: To investigate the effects of cent ra l disordered occlusion on the thickness of TMJ disc. Methods:The thickness of temporomandibular joint disc was measured in 5 cadavers with centr al disordered occlusion, including secondary malocclusion caused by loss of post erior tooth for a comparable long time with collapse of neighbor teeth and supra -eruption of its antagonized tooth, the supra-erupted third molar resulted fro m lack of antagonized tooth for a comparable long time and individual posterior tooth cross bite or reverse cross bite asymmetrically. Other 7 cadavers without central disordered occlusion served as controls. All samples were examined histo logically for the TMJ disc thickness. Out of 18 New Zealand rabbits, aged 5 mont hs, 9 were treated orthodontically to pull the first premolar move medially, occ luding with its opposite un-coincidently, central disordered occlusion was grad ually induced. The other 9 rabbits served as blank controls. The TMJs were sampl ed 3 months after beginning of the experiments, stained with HE and observed und er microscope. Results: In both cadavers and animals, the TMJ di sc was found much thicker in central disordered occlusion group than that in the control group (P

Objective To study the risk factors influencing the prognosis in the children patients with acute gastrointestinal dysfunction and to seek their therapeutic measures. Methods The clinical data of 125 cases patients with acute gastrointestinal dysfunction were retrospectively analyzed. The risk factors possibly influencing the prognosis were analyzed by multivariate statistical Logistic analysis. Results Among 125 children patients, 61 cases died, and the mortality rate was 48.8%. Logistic regression analysis indicated that poor circulation, cardiovascular system failure, hepatic failure, brain failure were significant risk factors of death associated with acute gastrointestinal dysfunction. (OR = 4.156, 3.330, 6.903, P<0.05 or<0.01). Conclusions Poor circulation, cardiovascular system failure, hepatic failure and brain failure are significant risk factors of death associated with acute gastrointestinal dysfunction.

To investigate and step in the compliance of clinician hand hygiene, we used vari-ous management tools of the quality control circle (QCC), and then compared the change of the com-pliance before and after any operations. Firstly, we followed this 5 steps: selecting themes, drafting plans, grasping current situations, setting goals and analyzing objectives. Then, we formulated and im-plemented the interventions pertinently. All of the QCC members participated actively in the whole process. The compliance of clinician hand hygiene was improved from 41.11%to 57.59%. The realiza-tion rate was 115.97%, the progress rate was 40.99%, and the hand hygiene compliance of hand hy-giene in different time was significantly improved with the average value 1.25. Standardized result formed by quality control circle activity had a comprehensive promotion in the hospital and promoted the management of hospital infection and the development of hospital.

Objective:To explore the role of lectin-like oxidized low density lipoprotein (ox-LDL) receptor(LOX1) in ox-LDL stimulating endothelial nitric oxide(NO) production. Methods: LOX1 mRNA expression was detected by reverse transcription-polymerase chain reaction(RT-PCR). The quantity of NO was detected by Enzyme-method. Results: Incubation of ox-LDL increased endothelial NO production and LOX1 mRNA expression. When HUVECs were incubated with ox-LDL as well as the inhibitor of LOX1, polyinosinic acid,the increase of NO production and LOX1mRNA expression were attenuated. Conclusion: Ox-LDL enhanced endothelial NO production in a concentration-dependent manner, and the effect of ox-LDL on endothelial NO was mediated by LOX1.

Objective To investigate the diagnostic value of multiplanar reformation (MPR)reconstruction for the detection of traumatic diaphragmatic rupture (TDR) in multi-slice CT examination.Methods Thirty six cases with thoracoabdominal trauma, including 21 cases with and 15 cases without TDR confirmed by surgery, received multi-slice CT examination. They were enrolled in this study. Three experienced radiologists retrospectively analyzed the axial and MPR images. The diagnostic criteria for TDR included abnormally elevated hemidiaphragm, diaphragmatic discontinuity, the "collar sign" or "dependent viscera "sign. Referenced to surgical results, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of axial and MPR images in detection of TDR were calculated. The McNemar was used to investigate the differences between axial and MPR images in the detection of diaphragmatic discontinuity and "collar sign", and the differences between axial and MPR images of these two signs in TDR diagnosis. Results The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of axial images in detection of TDR were 71% ( 15/21 ), 80% ( 12/15 ), 83% ( 15/18 ),67% ( 12/18 ) and 75% ( 27/36 ), respectively; of MPR images, they were 86% ( 18/21 ), 93%(14/15), 95% ( 18/19 ), 82% ( 14/17 ) and 89% ( 32/36), respectively. By axial images, twelve diaphragmatic defects or interrupts were identified in nine cases, and "collar sign" was identified in six cases. By MPR, 20 diaphragmatic defects or interrupts were identified in 15 cases ( P = 0.125 ), and "collar sign" was identified in 14 cases (P =0.021 ). The sensitivity and specificity of diaphragmatic defects or interrupts for TDR diagnosis in axial images were 43% (9/21) and 80% ( 12/15 ), respectively;in MPRimages, they were71% (15/21) (P=0.125)and93% (14/15) (P=0.500), respectively.The sensitivity and specificity of "collar sign" for TDR diagnosis in axial images were 29% (6/21) and 100% ( 15/15), respectively; in MPR images, they were 67% ( 14/21 ) (P =0. 021 ) and 100% (15/15)( P = 1.000), respectively. Conclusions MSCT presented good sensitivity, specificity and accuracy for the diagnosis of TDR. MPR images were useful supplements for axial images in TDR diagnosis which improved the diagnosis.
