Objective To investigate the relationship of D-dimer(DD) and fibrinogen levels in blood plasma and diabetic nephropathy(DN).Methods According to the results of urinary albumin excretion rate (UAER), 98 cases of type 2 diabetas were divided into simple diabetic mellitus ( SDM), early diabetic nephropathy ( EDN) and clinical diabetic nephropathy (CDN); other 45 healthy persons were employed as control. Plasma levels of DD and the fibrinogen of all groups were examined.Results There was significant difference of DD and fibrinogen levels in all groups as compared with control group (P

Objective To investigate the diagnostic value of biexponential model of DWI in nontypical hippocampal sclerosis (HS) of the youth.Methods DWI with multiple b values were performed on 75 youths with right temporal lobe epilepsy and 20 healthy youths(control group).There were no abnormalities in hippocampus on conventional MRI.11 of 75 patients were proved right HS by surgery and pathology (HS group).Compare the volume of the right hippocampus and their D,D? and f values in HS group and control group.Results There were statistical differences in D and f values between HS group and control group (Z=-3.08,Z=-2.23,P<0.05). There were no statistical differences in the volume of hippocampus and D? values between two groups (Z=1.77,Z=-0.19,P>0.05). Conclusion When HS does not have typical appearances on conventional MRI,D and f values can provide help from diffusion and the perfusion of microcirculation aspects.

Lower urinary tract symptoms due to benign prostatic hyperplasia is of great prevalence among ageing males,and it can markedly affect patients' quality of life.Personalized drug therapy according to genetic characteristics is the ideal choice for this problem.Here we summarized the latest research findings on the associations of gene polymorphisms with drug efficacy and adverse reaction in the treatment of benign prostatic hyperplasia/urinary tract symptoms.

Objective To study of relationship between elderly people's alexithymia and mind-reading. Methods There were 108 old people over 70 years old, tested by mind-reading,cognitive ability and twenty-item Toronto alexithymia scale. Results There were significant difference in mind-reading(16.00±4.84, 19.36±2.91,t =3.38,P ＜0.01), memory span(5.80±1.42,7.18±1.13,t =4.28,P ＜0.01), working memory( t =4.05,P ＜0.01),processing speed( t =-4.80,P ＜0.01) between high and low alexithymia groups.Alexithymia scores were negatively related to the scores of mind-reading, memory span,working memory,processing speed,correlation coefficient was 0.227( P <0.05),-0.377( P <0.01),-0.334( P <0.01),-0.470( P <0.01),respectively. With mind-reading,cognitive processing and educational level as independent variables,with total scores, F1, F2, and F3 of TAS as dependent variable,respectively,the regression equation of total scores was significant( F =8.594,P ＜0.01), and the one of F1 was significant( F =8.796,P ＜0.01),but the one of F2( F =1.735,P ＞0.05) and F3( F =1.181,P ＞0.05) was not significant. Conclusion Elderly people's alexithymia is negatively related to mind-reading and several cognitive abilities. Mind-reading could affect emotional recognition, but not affect emotional description and export-oriented thinking.

Objective To investigate the characterized imaging in conventional MRI, get information about the metabolites in basal ganglia from proton MR Spectroscopy(~1H-MRS) of acute bilirubin encephalopathy(ABE) and find out the relationship between those changes and bilirubin levels. Methods Twenty-eight patients with acute bilirubin encephalopathy and 15 normal neonates underwent MR and ~1H-MRS examinations T_1 WI, T_2WI and DWI were collected via conventional MRI scanning of all neonates. All patients underwent multi-voxels scanning and 15 of them had single voxel scanning. ~1H-MRS used point resolved spectroscopy (PRESS) both in multi-voxels and single voxel scanning. The data of them were acquired from the ROIs placed in basal ganglia and globus pallidus, respectively. The metabolites including NAA choline, Lactate, glutamate and glutamine, myoinositol and creatine were quantitatively analyzed to compare them between the control group and the case group. Equality of variance between patient data and normal values were tested by using the two-tailed t test. The case group was divided into three groups of 342.0 μmol/L < TSB ≤ 427. 5 μmol/L,427.5 μmol/L < TSB ≤ 513.0 μmol/L, TSB > 513.0 μmol/L including 8,9,11 patients, respectively. Analysis of variance was used for statistics. Results Conventional magnetic resonance imaging showed symmetrical high signal of T_1WI in globus pallidus of 23 patients. The case group and the control group were significantly different. Single voxel ~1H-MRS revealed that the relative concentrations of Glx/Gr and mI/Cr in the control group were 0.95±0.23, 0.57±0.20, respectively, While those in case group were 1.45±0.37, 0.74±0.23, respectively. There were significant differences between two groups (t =2. 13,4. 40,P =0.04,0.00 respectively). Multi-voxels scanning 1H-MRS revealed that Glx / Cr were 0.51±0.36 in case group and 0.29±0.18 in control group. There was also a significant difference between two groups (t =2.17,P =0.03). And the values of Cho/Cr, NAA/Cr and Lac/Cr were not significantly different. The results were same in multi-voxels ~1H-MRS. Total bilirubin level and the concentration of metabolites in the brain do not have obvious correlation. Conclusions ABE has a characteristic signature which is symmetrical high signal of T_1 WI in globus pallidus on conventional MBI; The values of mI/Cr and Glx/Cr remarkably increase as detected by ~1H-MRS, which is generally in agreement with what has been known about bilirubin pathology.

o statistical difference between WMD group and control group (t = 1.83, t = 0. 88, P 0. 05). Conclusion Conventional MRI is able to quantify the brain maturation and prognosis of premature infants using TMS.

The membrane fluidity of mitochondria isolated from langendorff perfused rat hearts was studied with ESR spin labeling technique and TBA method was used to detect the content of lipid peroxide. After total ischemia for 40min followed by a 20min reperfusion the 10-DSA region of the mitochondrial membrane showed significantly increased S (0.1(?)2?0.006) and ?_c(7.13?0.09?10~(10)sec) values (i. e. a decrease of membrane fluidity)in comparison with aerobic control (S=0.103?0.007); ?_c=6.86?0.20?10~(-10) sec) (P0.05). In addition, we found that DS182 could remove O_2~? produced by O_2~? generating system. Our results have showed that DS-182 is a potent scavenger of superoxide. The protective effect of DS-182 on mitochondria during ischemia/reperfusion might be due to its antioxidative activity。

This study was performed on rabbits to examine the changes of calmodulin (CAM) and cAMP in the myocardium during ischemia and reperfusion by radioimmunoassay method. The result showed the levels of CaM and cAMP increased at 20 min of ischemia. Although these two parmeters were unchanged at 40 min of ischemia as compared with the changes at 20 min, they were changed during reperfusion at different times of ischemia. At 20 min ischemia following 10 min reperfusion, the content of CaM decreased, the content of cAMP increased. On the basis of 40 min ischemia, reperfusion induced opposite changes: CaM increased, cAMP decreased. The possible mechanism of these changes was discussed.

Objective To detect the expression of TrkA in the brain of the Wistar rats during the embryonic phase.Methods Adult Wistar rats were fed in one cage.It was E0 day when sepermia were found in vaginal suppository and vaginal smear.The expressions of TrkA in the brain of Wistar rats during various brain regions were observed by immunohistochemistry on E13,E15,E17,E19 and E21 day. Results On E13 day no obvious expression of TrkA was observed in the embryonic brain.The expression of TrkA had an obviously increasing tendency in the cortex of telencephalon from E15 day to E17 day.And on E17 day,the positive rate of the expression of TrkA reached the second peak.While on E19 day,the expression of TrkA had a temporary decreasing.Then on E21 day the expression of TrkA reached the highest peak.The striatum and hippocampus developed later than the telencephalon till E17 day,and the expressions of TrkA during these stages were same as the cerebrum.Conclusion From E15 to E17 day,obvious expressions of TrkA are observed in the embryonic telencephalon,and it accords with embryonic induction.
