Objective To investigate the feasibility of differentiation between prostate cancer and prostatitis by using metabolic ratios provided by 3D 1H Magnetic Resonance Spectroscopic Imaging (MRSI). Methods Metabolic changes were evaluated in 42 voxels with prostate cancer and 30 voxels with prostatitis in the peripheral zone using MRSI. The results were based on the pathologic findings by biopsy. The (choline + creatine)/Citrate (CC/C) ratio and the changes of choline and citrate levels were evaluated in each voxel with cancer or prostatitis, t test was used to determine the power of the CC/C ratio in differentiation between prostate cancer and prostatitis. Results The CC/C ratio for cancer voxels (1.28±0.41) was significantly different from the ratio in the voxles with prostatitis (1.03±0.40), t=6.45, P<0.05, due to greatly increased choline level in the cancer voxels. When CC/C ratio of 0.8 was taken as the criteria for the diagnois of prostate cancer, the sensitivity, specificity and accuracy were 65.5%, 71.4% and 66.7%, respectively. Positive predictive value(PPV)and negative predictive value(NPV) were 90.5% and 33.3%, respectively. The CC/C ratio was higher than 0.86 in 66.7% voxels with prostatitis (20 voxels of total 30 voxels), which mostly depended on the level of choline. When citrate level was used as an auxiliary index to evaluate prostatitis (Cit/norm, Cit≥0.75), the misdiagnosis rate of prostate cancer was reduced to 26.6%(8 voxels of total 30 voxels). Conclusions The metabolic ratio of CC/C can be used to differentiate prostate cancer from prostatitis. The misdiagnosis rate is reduced when citrate is not or slightly decreased relative to normal citrate level (Cit/norm, Cit≥0.75).

Objective To explore the clinical application of dual-soure CT(DSCT) in coronary artery.Methods 51 patients suspected with coronary artery disease underwent both DSCT coronary arteriography and selective coronary angiography(CAG), the DSCTA results were compared with that of CAG.Results DSCT coronary arteriography in 51 patients at any heart rate was successful.Coronary artery branches and part sub-branches were clearly displayed by DSCT angiography.Stenosis or obstruction of 166 coronary artery branchs in 51 patients were showed ,of them,150 branches were confirmed by CAG. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of DSCTA were 100%, 90%, 90.4%, 100% and 94.8% respectively.Conclusion DSCT is a valuable method in detecting the diseases of coronary artery with lower dose. The accuracy of the DSCT is approximate to the CAG.

OBJECTIVE:To observe the clinical efficacy and safety of piperazine ferulate combined with glutathione in the treatment of diabetic nephropathy. METHODS:80 patients with diabetic nephropathy in our hospital were divided into observation group and control group according to random number table,with 40 cases in each group. Both groups was given general treatment as blood glucose,blood lipid and blood pressure control. Control group was additionally given Reduced glutathione tablets 400 mg, tid,on the basis of general treatment. Observation group was additionally given Piperazine ferulate tablets 100 mg,tid,on the ba-sis of control group. Both groups were treated for 12 weeks. The fasting plasma glucose(FPG),2 h postprandial plasma glucose(2 hPG),blood pressure,blood lipid,serum creatinine (Scr),blood urea nitrogen (BUN),24 h urinary total protein and albumin, urine β2 microglobulin(β2-MG)and N-acetyl-β-glucosaminidase(NAG)of 2 groups were detected before and after treatment. The occurrence of ADR was observed. RESULTS:Before treatment,there was no statistical significance in FPG,2 hPG,blood pres-sure,blood lipid,Scr,BUN,24 h urinary total protein and albumin,urine β2-MG and NAG between 2 groups(P>0.05). After treatment,above indexes of 2 groups were improved significantly,and the observation group was better than the control group, with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:In the treatment of diabetic ne-phropathy,piperazine ferulate combined with glutathione can improve blood glucose,blood pressure,blood lipid levels and renal function with good safety.

Purpose To study the effect of overexpressing either wild type or a familial Alzheimer disease mutant presenilin 1 (mPS1) on tau phosphorylation in neuroblastoma NG-108 cells. Methods Three different plasmids transfected NG-108 cells respectively. Immunostaining and confocal microscopic technique were used to study the distribution of presenilin 1 and phosphorylated tau. Immunoblot test was applied to investigate the change of tau phosphorylation. Results Immunostaining showed that in brain of sporadic Alzheimer disease, PS1 mainly distributed in neuron and partially colocalized with the phosphorylated tau. Immunoblot tests showed that the cells transected either wild type PS1 or mPS1 contained more phorphorylated tau than the control cells. However, MTT test showed no significant difference between mock transfected cells and the wPS1 or mPS1 transfected cells. In addition, after transfection of the constructed PS1-EGFP vector, overexpressed EGFP-PS1 was located at cell surface membrane and subcellular organelles at earlier time at 12 hr, then EGFP-PS1 diffused in cytosol. Immunocytochemical observations demonstrated that some of the PS1-EGFP transfected cells contained more phosphorylated tau protein, which formed aggresome with PS-1-EGFP. When treated with phosphotase inhibitor okadaic acid, in the PS1-EGFP transfected cells accumulated more phosphorylated tau than the un-transfected cells. Conclusions Wild type PS1 is possibly involved in tauopathy in sporadic Alzheimer's disease.

Objective To observe the effects of thymosin alpha-1 on T cell subsets and gastricintestinal reac-tion of patients with gastricintestinal tumor. Methods Twenty patients with gastricintestinal tumor were divided into two groups, observe group(n = 10) received thymosin alpha-1 during chemotherapy, and control group(n = 10) only received chemotherapy, T cell subsets and gastricintestinal reaction were observed. Results Before chemotherapy, CD+4,CD+8 and CD+4/CD+8 of observe group were(43.7±7.5),(27.3±2.8) and (1.5±0.1), and control group were (39.4±6.3), (30.9±2.5) and (1.2±0.6). There was significant difference between them (P < 0.05). After chemotherapy, CD+4, CD+8 and NK cell were (40.6±6.8)、( 29.7±2.6) and (19.1±2.7), control group (35.9±5.7), (33.4±2.4) and (18.6±2.3). There was significant difference between them (P < 0.05). Effec-tive ratio of nausea and vomit of observe group were 72.5% and 60.0%, control group 40.0% and 33.3%, There were significant differences between them(P <0.05). Conclusion Thymosin alpha-1 may ameliorate the function of T cell subsets and gastricintestinal reaction of patients with gastricintestinal tumor.
