By software and signal analysis,visualization of medical NMR signals becomes possible.The T1,T2 resonance frequency value reflecting human tissue characteristics,and the FID,echo wave as well as other curves reflecting the intensity of signals,can contribute a lot to the teaching of the applied analysis of clinical NMR and MRI principles.

Objective To obtain a lasting and purified cell line of vascular smooth muscle cells (VSMCs) by primary culture, and to provide these test materials related research. Methods The primary and transfer culture was done by tissue - piece inoculationand trypsin digestion,respectively. The cells were frozen in liquid nitrogen,and cultured cells were identified by phase contrast microscopy and immunohistochemical SP kit. Results 85% of inoculated tissue pieces survived. More than 90% of VSMCs regrew in transfered culture. The frozen cells could recover their proliferation by several culture transfers. The VSMCs showed the typical "peak and valley" characteristics under microscopy. Immunohistochemical staining with antibody against SM - a - actin expression in these cells was positive. Conclusion The tissue - piece inoculation is a simple method for obtaining satisfactory VSMCs in short term.

Objective To explore effects of hcmoperfusion on toxic ingredients in plasma of rabbiis with a-cute intoxication of Radix Aconiti Kusmezoffii Monkshood.Method Sixteen male Japanese Giant Ear Rabbits were randomly divided into acute poisoning(AP)group and acute poisoning + hemoperfusion(AH)group(8 an-hnals in each group).Acute poisoning models were established in rabbits of both groups with intragastric adminis-tration of Radix Aconiti Kusmezoffii Monkshood liquid in dose of 1 mL/kg in order to produce arrhythm which oc-curred within ode hour after intragastric administration was regarded as the criteria of successful animal model.and then hemoperfusion with active carbon was performed for 2 hours in AH group.The pathological chanses of brain,myocardium and hepatic tissues were observed.The plasma concentrations of toxicants including mesaconitine,a-conitine and hypaconitine were measured by using HPLC-MS at 1 h,2 h,3 h,and 6 h after poisoning.Student's T test was used to identify the significance.Results The brain.myocardium and hepatic tissues of the rabbits in AP group showed hyperemia and edema which were attenuated after hemoperfusion.The plasma concentrations of mesaconitine,aconitine and hypaconitine revealed no significant differences between AP group and AH group with-in one hour after poisoning(P＞0.05),while at 2 h and 3 h after poisoning,the plasma concentrations of mesaconitine were(2.11±1.08)ng/mL,(2.02±1.46)ng/mL,respectively,aconitine(39.70±9.31)ng/mL,(19.71±16.06)ng/mL,respectively,and hypaconitine(1.70±0.71)ng/mL,(2.12±1.33)ng/mL,respec-fively in AH group,and they were significantly lower than those in AP group(P＜0.05).Conclusions The the plasma concentrations of mesaconitine,aconitine and hypaconitine were lower and the histopathological changes were attenuated after hemoperfusion.Hemoperfusion is a good intervention for acute intoxication of Radix Aconiti Kusmezoffii Monkshood.

Apolipoprotein A5(ApoA5)level and other indices were determined in patients with type 2 diabetes mellitus and healthy individuals.Compared to control group,ApoA5 level in the diabetic group was lower (P

Objective To observe the poisoning components in plasma and histological changes of rabbits with acute toxicity of aconitum kusnezoffii (草乌).Methods Eight rabbits were garaged with aconitum kusnezoffii liquor,aconitum poisoning model was reproduced,electrocardiogram (ECG) and blood pressure were recorded,the concentrations of aconitine,hypaconitine and mesaconitine in plasma after 0.5,1, 2,3 and 6 hours were measured,and the pathological changes of heart,liver and cerebral cortex were observed.Results After garage with poisoning liquor,arrhythmias and the declination of blood pressure, presenting a tendency of progressive aggravation [before garage:(121.98?16.77)/(110.66?8.78) mm Hg, 1 hour after garage:(102.98?8.34)/(90.22?5.85) mm Hg,2 hours after garage:(66.81?9.13)/ (53.40?6.32) mm Hg,1 mm Hg=0.133 kPa,all P

Objective To investigate the potential role and changes of CD14, TNF-ct and IL-10 in liver in Vibrio vulnificus septic rats, and detect the intervention effects of eefoperazone sodium combined with levofloxacin. Methods To make Vibrio vulnificus sepsis model (VV group) and drug intervention model (AA group) in rats, the expression of CD14, TNF-α, IL-10 in liver were detected by RT-PCR. Results Compared with normal control (NC) group,CD14 mRNA and TNF-α mRNA expression increased markedly at 2, 6, 9, 12, 16 h in VV group (P<0.05), IL-10 mRNA raised greatly at 9, 12, 16 in VV group (P<0.05). CD14 mRNA expression was also rised in AA group at 9 h(P<0.05). TNF-α mRNA at 9, 12 h and IL-10 mRNA at 9, 12, 16 h in the AA group increased (P<0.05). Compared with VV groups, CD14 mRNA expression diminished greatly at 9, 12, 16 h in AA group (P <0.05), TNF-α mRNA and IL-10 mRNA diminished in the AA group at 16 h(P<0.05). Conclusion The treatment with cefoperazone sodium and levofloxacin may reduce expression of CD14, TNF-α and IL-10 in liver of rats with VV sepsis, it may inhibit the level of pro-inflammatory/anti-inflammatory cytokines, thereby regulating the balance of the inflammatory response in VV sepsis.
