Objective To study the effects of preconditioning treadmill exercise on excitatory amino vacid changes in rats after the cerebral infarction and the protective effects against cerebral isehemia brain injury. Methods Thirty Sprague-Dawley rats were used in this study. Twenty-five rats were subject to an operation to establish the animal model of middle cerebral artery occlusion and divided into a isehemia group, an 1-week ex- ercise group (trained in the 4th week) , a 2-week exercise group (trained in the 3rd and 4th weeks) and a 4- week exercise group (trained for 4 weeks) , while the remaining 5 rats were subject to sham operation, and served as the controls. After 4 weeks of experiment, all the the rats were fixed on stereotactie apparatus for the brain microdialysis of the striatum. Then the focal middle cerebral artery ischemia and reperfusion were made with thread oeclussion in rats and microdialysis technique was used to collect extraeellular fluid in each period of pre-ischemia, ischemia (40, 80 and 120 min), and reperfusion (40, 80, 120, 160, 200 and 240 min) to detect the changes of the excitatory amino acid. At the same time the infarction volume was also measured at 24 hours after ischemia-reperfusion of the brain. Results The difference between any two groups was significant with regard to the volume of cerebral infarction (P < 0.05). Two weeks and four weeks of the preconditioning treadmill exercise couled significantly reduce concentration of Glu excessively released due to the ischemia (P < 0.01). Conclusion At least two weeks of preconditioning treadmill exercise can inhibit the excessive release of the important excitatory amino acid neurotransmitter glutamate, to some extent, in the process of the subse- quent ischemic brain injury and during reperfusion, which might be one of the protective mechanisms of move- ment against the early isehemie brain injury.

Objective To discuss effect of fasting and taking food on hemostasis effect of patients with gastric ulcer and bleeding. Methods 160 patients with gastric ulcer and bleeding were divided in-to the experimental group and the control group, the experimental group was allowed to take lower ho-moiothermy water gruel (liquid), the control group was required absolute fasting (not medication), until bleeding stop. The two groups adopted identical treatment and nursing. The lienable stomach tube was placed respectively, everyday pH value monitor and occult blood test were carried out by taking out gas-tric juice when fasting and 2 hours after meals. Continuous monitoring tests continued till occult blood test of gastric liquid became negative for 3 times. Stool was kept for occult blood test, at the same time the gastrointestinal tract symptom and bleeding condition were observed, routine blood test was carried out one every other day. The data underwent statistical analysis with SPSS13.0 statistics software package, compari-son between two groups used t test. Results The inner stomach pH value of the experimental group in-creased obviously, the average pH value and percentage of pH above 4 was evidently higher than those of the control group. The time of occult blood test of gastric liquid and stool turning to negative in the experi-mental group was shorter than those of the control group. Conclusions Taking food can elevate pH of gastric liquid, reduce damage caused by gastric acid to gastric mucosa, thus hasten hemostasis process and promote healing.

Objective To study the expression of plasma oxidized low-density lipoprotein (oxLDL) in children with acute phase Kawasaki disease (KD), and investigate its value for early prediction of coronary artery lesions in KD. Methods Totally 80 children with KD were collected. Children were divided into four groups by the results of echocardiogram of coronary artery in different periods: CAL1 group (children with coronary artery lesions (CAL+) both in acute and sub-acute phase, 8 cases), CAL2 group (children with CAL+in acute phase but recovery normal (CAL-) in sub-acute phase, 10 cases), NCAL1 group (children with CAL-in acute phase but occur CAL+ in sub-acute phase, 10 cases) and NCAL2 group (children with CAL- both in acute and sub-acute phase, 52 cases). The serum samples (before the use of intravenous immunoglobulin) were collected in acute phase. Twenty healthy controls and twenty fever controls were enrolled into the study, and their serum samples were collected. OxLDL was measured by enzyme linked immunosorbent assay (ELISA). They were compared using ANOVA, pairwise comparison LSD-t test. And ROC curve analysis was used to determine the threshold. Results Compared with the control groups,plasma oxLDL levels were higher in children with KD, both CA+and CAL-[(15.0±3.3) mU/L, (12.3±3.5) mU/L vs (9.2±2.2) mU/L, (8.0±2.3) mU/L, F=20.435, P<0.05]. Plasma oxLDL levels were increased more significantly in children with CAL+ than children with CAL- in KD [(15.0 ±3.3) mU/L vs (12.3 ±3.5) mU/L, t=2.28, P=0.002]. There was significant difference in the concentration of oxLDL between the groups of Kawasaki disease (F=5.068, P=0.003). Plasma oxLDL levels were significantly higher in the NCAL1 group than those in the NCAL2 group [(14.5 ±3.8) mU/L vs (11.9±3.3) mU/L, t=2.29, P=0.02], but there were no statistically significant difference between the NCAL1 group and CAL1 or CAL2 group [(14.5±3.8) mU/L vs (15.9±3.9) mU/L, (14.5±3.8) mU/L vs (14.2±2.7) mU/L, t=0.73, 0.20;P=0.41, 0.84]. ROCs analysis indicated that oxLDL≥13.83 mU/L, could be the threshold for the prediction of coronary artery lesions with the sensitivity of 0.607 and a specificity of 0.75. Conclusion OxLDL plays an important role in coronary artery lesions in KD. The coronary endothelial dysfunction is earlier than coronary dilatation, and oxLDL is expected to become a reliable early predictor of coronary artery lesions in KD.

ObjectiveTo investigate the value of combined measurement of serum alpha-fetoprotein (AFP), Dickkopf-1 (DKK1), and cytoskeleton-associated protein 4 (CKAP4) in the diagnosis of hepatocellular carcinoma (HCC). MethodsA total of 122 patients with HCC (76 patients in the early stage), 152 patients with liver cirrhosis, and 105 patients with chronic hepatitis B, who were admitted to The First Affiliated Hospital of Soochow University from January 2013 to December 2017, were enrolled, and 101 individuals who underwent physical examination during the same period of time were enrolled as healthy control group. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the chi-square test was used for comparison of categorical data between multiple groups. A binary logistic regression analysis was used to obtain the new variable of predicted probability, and the receiver operating characteristic (ROC) curve analysis was performed for each index and predicted probability to investigate the area under the ROC curve (AUC), sensitivity, and specificity of the three indices used alone or in combination. ResultsThe HCC group had significantly higher serum levels of AFP, DKK1, and CKAP4 than the liver cirrhosis group, the chronic hepatitis B group, and the healthy control groups (F=121.618, 84.559, and 91.769, P<0.001). The combination of AFP, DKK1, and CKAP4 had an AUC of 0.967 (95% confidence interval [CI]: 0.950-0.984), a sensitivity of 0.869, and a specificity of 0.980, which were significantly higher than the AUCs, sensitivities, and specificities of the three indices used alone (all P<0.05). The combination of the three indices had an AUC of 0.965 (95%CI: 0.942-0.988), a sensitivity of 0.868, and a specificity of 0.980 in the diagnosis of early-stage HCC, which were significantly higher than the AUCs, sensitivities, and specificities of the three indices used alone (all P<0.05). ConclusionCombined measurement of serum AFP, DKK1, and CKAP4 improves the accuracy, sensitivity, and specificity of HCC diagnosis and thus has an important clinical value in the screening for and early diagnosis of HCC.

Objective To investigate alterations of blood perfusion in subcortical regions in patients with Parkinson′s disease (PD) by three dimentional arterial spin labeling (ASL) magnetic resonance imaging (MRI). Methods Thirty patients with PD and 40 control subjects were recruited from the inpatient and outpatient of the Department of Neurology of Northern Jiangsu People′s Hospital during October 2014 to October 2016, and routine brain MRI and 3D pseudo?continuous pulse ASL were performed on all the subjects. The cerebral blood flow (CBF) maps derived from 3D ASL were coregistered to the Montreal Neurological Institute brain space. The stereo?templates of bilateral caudate nucleus, putamen nucleus, globus pallidum and thalamus from Anatomical Automatic Labeling were used as region of interest (ROI) to exstract absolute CBF values in these subcortical regions, respectively. The CBF ratio (rCBF) values represented by individual whole brain CBF divided by each of the regional CBF were also calculated in consideration of the difference between individual whole brain CBF. The CBF and rCBF values were compared respectively between groups by one?way analysis of variance. Results The subcortical CBF values (ml·100 g-1·min-1) for each ROI in PD (caudate nucleus (left: 35.32±6.47, right: 36.17±7.07), globus pallidum (left: 40.42 ± 5.83, right: 40.18 ± 5.70), putamen nucleus (left: 41.97 ± 6.12, right: 42.91 ± 6.43) and thalamus (left: 46.58 ± 7.71, right: 49.11 ± 7.10)) were significantly lower than that in the control group (caudate nucleus (left: 41.38±7.05,right: 41.63±6.85), globus pallidum (left: 45.65±8.35,right: 45.53±8.94), putamen nucleus (left: 48.49±8.78, right: 48.99±8.88) and thalamus (left: 54.32±11.94,right: 56.21±11.98), F=13.58, 10.56, 12.11, 10.06, 8.59, 8.23, 9.57, 8.30, P=0.000, 0.002, 0.005, 0.005, 0.001, 0.002, 0.003, 0.005, respectively ). The whole brain mean CBF values of each subject were also extracted and compared bewteen groups, and mean CBF values (ml·100 g-1·min-1) in PD patients (42.14±9.61) decreased significantly than those in the control group (51.59±9.67, F=16.42, P<0.01), and there was a 18.31% decrement in whole brain mean CBF in the patient group. However, rCBF values for almost all subcortical ROIs of the patients significantly increased when compared with the control group. Conclusions The decreased absolute cerebral blood perfusion involved not only subcortical regions, but also the whole brain level in the course of PD. The CBF metabolism in patients with PD may have been redistributed, with relative hyperperfusion in the subcortical brain regions contrast to the whole brain perfusion level of patients themselves.
