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 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.

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 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 explore the effect of autophagy on process of high phosphate salt induced vascular smooth muscle cell (VSMC) calciifcation in experimental rats. Methods: Rats’ model of VSMC calciifcation was induced by phosphate incubation. VSMC were divided into 3 groups:①Control group,②Calciifcation group which included 3 subgroups as 4-day subgroup, the cells were cultured by 3.2 mmol/L phosphate for 4 days, 6-day subgroup and 8-day subgroup,③Calciifcation+ 3-MA (autophagy inhibitor) group, in which the 8-day cells were cultured with 5mmol/L 3-MA. Calcium nodule formation and calcium deposition in VSMC were measured by Alizarin red staining and o-cresolphthaleincomplexone method, protein expressions of Runx2, α-SMA and LC3 II were examined by Western blot analysis, autophagosome formation in VSMC was measured by transmission electron microscope and the localization and expression of Runx2 and LC3 II in VSMC were observed by immunolfuorescent microscope. Results: Compared with Control group, the cells at 8-day subgroup showed more calcium nodules, higher calcium deposition, increased protein expressions of Runx2, LC3 II, more autophagosome and decreased α-SMA expression, allP<0.05. Compared with 8-day subgroup, the cells in Calcification+3-MA group presented increased calcium deposition, decreased lfuorescence distribution of LC3 II and more cells with positive Runx2 protein expression, all P<0.05. Conclusion: Autophagy has the protective effect on process of phosphate induced VSMC calciifcation in experimental rats.
