Objective To probe into the changes of rats' plasma SOD,MDA,NO and rectal temperature at moist heat and wound stress in order to build a basis for research of enhancing resistance to stress resporise in human. Methods 56 moist beat and wound rats were randomly divided into the control group and the nutrition group with 28 rats in each group.then each group was subsequently divided into 4 period oftime.All the backs of rats were scalded in superficial degree Ⅱ by 99℃water and exposed to the same conditions:temperature at(37.O±0.5)℃and relative humidity at(65±5)%.The control group' was imbued with double-distilled water for one week,while in the nutrition group,compound nutrient was imbued for one week.SOD,MDA,NO and rectal temperature at 4 time points were compared between the two groups.Results The differences of rectal temperature,NO and SOD changes between the control group and the nutrition group were remarkably significant.Conclusions Early nutrition is effective in reducing stress,decreasing organ injury caused by NO,SOD and MDA level and alleviated the damage of body.

Objective To explore whether depressive disorder is one of risk factors for coronary artery disease (CAD) in enrolled patients and observe the level of inflammation markers in coronary artery disease patients with depression. Methods In all patients, we recoded clinical information and data from Hamilton Depression Rating Scale for Depression( HRSD)and measured concentration of monocyte chemoattractant protein-1 (MCP-1), tumour necrosis factor α (TNFα) and hypersensitive C-reaction protein (hsCRP). Results Among 87 patients with coronary artery disease, depressive disorder was diagnosed in 26 patients, the prevalence of depressive disorder was 29. 9%. Among 101 patients without coronary artery disease, 12 patients were suffering from depressive disorder, the prevalence of depressive disorder was 11.90%. The prevalence of depressive disorder in coronary artery disease group was statistically higher than that in non-coronary heart disease group (29.8% vs.11.9%, P<0. 01). The incidence of coronary artery disease was associated with age, hypertension,diabetes mellitus, hypercholesterolemia and depression. Life events and stage of heart function occurred differently between CAD patients with and without depression (P<0. 05). There were no differences in the degree of coronary artery stenosis and the type of treatment (P>0. 05) between the two groups. There were higher concentration of MCP-1 in coronary artery disease patients with depression, but no remarkable difference in hsCRP and TNFa.Conclusions There is high prevalence of depressive disorder, which is one of risk factor for coronary artery disease. The depressive disorder may be associated with inflammation biomarker in patients with coronary artery disease.

Objective To study the clinical nursing significance of ECG monitor in primary PCI for AMI patients and the relation of changes in ECG and the reperfusion of infarction related artery.Methods Regressional analysis was made in ECG changes including different types of arrthymia,degree of ST segment regression,and their relation between the reperfusion of infarction related artery before and after interventional therapy in AMI patients.Results In 468 AMI patients,142 patients had ventricular arrhythmia before therapy.After interrentional therapy,285 patients were co-morbid with accelerated ventricular tachycardia,203 patients with transient ventricular tachycardia or R-on-T phenomenon,62 patients with ventricular fibrillation and received asynchronous electriacal cardioversion.Twenty four patients had new onsent of Ⅱ-Ⅲ degree atrio-ventricular block and 45 patients had bradycardia or sinus arrest.The atrio-ventricular blook in 10 patients before PCI disappeared after the operation.There are 301 patients with apparent ST segment regression(ST segment regressed ≥50%,57 patients with partial ST segment regression,and 29 patients without ST segment changes.Conclusion Arrhythmias always accompanied with IRA reperfusion.Careful monitoring of ECG is essential for patients' safety after AMI.Obvious ST segment is observed in sufficient IRA reperfusion.However,poor regression of ST segment as well as haemodynamics disorder and cardiogenic shock is observed in patients with poor reperfusion or subacute occlusion of IRA.

Objective To assess the dlagnostic value of a triple stimulation technique(TST)for benign monomelic amyotrophy(BMA). Methods A total of 15 BMA patients and 15 healthy control subiects were exam-ined with the TST.The latent periods,amplitudes,areas and durations of the negative waves of the compound muscle action potential(CMAP)and motor evoked potential(MEP)induced by the stimulation were recorded,and the de-creasing ratio of amplitudes and areas in the two groups were analyzed. Results There were significant differences in amplitude and area ratios between the BMA patients and the healthy control subjects.Both ratios were significantly lower in the BMA patients. Conclusion TST has some value in diagnosis of BMA.

Objective To study the effect of granulocyte-macrophage colony-stimulating factor(GM-CSF)on angiogenesis of rat with acute myocardial injury induced by isoproterenol(Iso). Methods A total of 60 adult male Wistar rats were randomly divided into 3 groups: normal control group, GM-CSF pretreatment group (GM-CSF group), and lso injury group, 20 rats in each group. GM-CSF group was administered recombinant human(rh)GM-CSF(5.0 μg/kg), through tail intravenous injection once a day for three days. Then the GM-CSF group and the Iso injury group were anesthetized by intraperitoneal injection of lso( 15.0 mg/kg) once a day for three days. The same dose of saline was administered in the same way to the control rats. Ten days after injection, pathological changes of myocardial damage and infarct area were examined by immunohistochemistry. The mRNA expression levels of polypeptide antigen (CD34), vascular endothelial growth factor (VEGF) and its receptor KDR/flk- 1 were measured by RT-PCR. Results The difference of myocardial necrosis area between groups was statistically significant(F=10.07, P < 0.01), in which GM-CSF group[(37.37 ± 12.98)%] was significantly less than Iso injury group[(45.51 ±14.96)%, P < 0.05]. The difference of myocardial neovascularization density index of rats between groups was statistically significant ( F = 25.54, P < 0.05 ), in which GM-CSF group [(3980.05 ± 477.22) No/mm2] was significantly higher than Iso injury group((2605.93±361.49)No/mm2,P<0.01).The differences of myocardial CD34,VEGF,KDR/flk-1 mRNA expression between groups were statistically significant(F=17.83,4.29,4.10,all P<0.01).Compared to Iso mjury group[CD34(23.85±6.06),VEGF(31.80±8.05),KDR/flk-1(30.16±8.01)]were higher in the GM-CSF group[CD34(44.04±10.13),VEGF(49A±11.59),and KDR/flk-1(46A9±7.90),all P<0.01].The expressions of myocardiM VEGF mRNA and its receptor KDR/flk-1 mRNA was positively correlated(r=0.725,R2=0.526,P<0.01).Conclusions GM-CSF prelreatmcnt increases the density ofnew blood vessels in myocardium,and reduces the Iso-induced myocardial injury in rats.

Objective To perform a spatial analysis of myocardium uhrastructure and the activity of mitochondrial succinate dehydrogenase in sub-acute Keshan disease. Methods Myocardium samples were collected from the cases with sub-acute Keshan disease and non-myocarditis(control), and their ultrastructure was observed under electron microscope. The density of mitochondrion volume and cristal membrane and its volume were measured by a point-counting method, while mitochondrion volume was estimated by water displacement method, succinate dehydrogenase activity of mitochondrion by iron-copper method in sub-acute Keshan disease and non-myocarditis cases. Results The volume ratio of mitochondrion to the cell on myoeardium [(47.79±6.20)%], the area ratio of mitochondrion to sarcoplasm [(55.06±6.50) %], mitochondrion to myofibrils [(1.43±0,41)%], mitochondrion section area[(0.78±0.15)μm2], and ratio of the lesion of cristal membrane area to the matrix area and mitochondrion volume[(67.14±13.96)%, (44.62±13.44)%]in sub-acute Keshan disease group were obviously higher than those in control [(33.20±7.62)%, (38.07±9.43)%, (0.71±0.33)%, (0.44±0.07)μm2, (14.11± 12.51)%, (9.34±11.28)%; t = 3.75,7.93,6.61,36.40,52.65,37.51, all P < 0.05]. The volume ratio of myofibrils to cell[(34.52±5.12)%]and the area ratio of cristae mitochondria to matrix[(32.43±14.42)%]in sub-acute Keshan disease group was obviously less than those in control [(48.51±4.30)%, (86.04±12.37)%; t = 9.85, 53.46, both P < 0.05)]. Succinate dehydrogenase activity was negative in sub-acute Keshan disease group. Conclusions Myocardium ultrastructure changes in sub-acute Keshan disease including the increase of volume and areas of mitochondria and the damage of the cristal membrane in mitochondria. Succinate dehydrogenase activity is decreased or even disappeared.
