OBJECTIVE:To study the enhancing effects of azone at different concentrations on percutaneous permeation of compound tinidazole gel and to find out the best concentration.METHODS:Using vertical Franz-type diffusion cell and dif?ferent concentrations of azone as enhancer,the concentrations of tinidazole,chloramphenicol and salicylic acid in permeation solution were measured by RP-HPLC,then cumulative permeation quantity(Q)was calculated.RESULTS&CONCLUSION:Azone at different concentrations could promote the permeability of3ingredients of compound tinidazole gel,and2%azone had the most obvious permeation-enhancing effect.

Objective To observe the effects of Di ao Xin xue Kang on connexin 43 ( Cx43 ) , in order to make clear the protective mechanism against ischemia -induced arrhythmias .Methods The rats were randomly divided into 3 groups according to the digital table:SM operation group(group SM,n=10),ischemia group(group IM,n=10),Di ao Xin xue Kang group(group DA,n=10).Myocardial infarction was induced by legation the left anterior descending coronary artery for 120 min.The expression of Cx43 of the ischemic myocardium was studied by immunohistochemistry technique .The ventricular arrhythmia was observed , and MDA, SOD levels were measured . Results Compared with the SM group ,the arrhythmia score[(3.8 ±0.7)points vs.(0.7 ±0.2)points,t=13.466, P<0.01]and serum MDA level[(8.3 ±0.8)nmol/mL vs.(4.2 ±0.7)nmol/mL,t=12.197,P<0.01]in the IM group were significantly increased,SOD activity in the IM group[(68.2 ±5.5)U/mL vs.(144.1 ±7.9)U/mL,t=24.932,P<0.01]decreased,and serum Cx43 content[(0.39 ±0.06) vs.(0.92 ±0.05),t=21.459,P<0.01] significantly decreased.Compared with IM group,the arrhythmia score of the DA group [(2.6 ±0.8) vs.(3.8 ± 0.7),t=3.570,P<0.01]decreased,and serum Cx43 content[(0.60 ±0.08) vs.(0.39 ±0.06),t=6.641,P<0.01]increased and distributed regularly.Conclusion Di ao Xin xue Kang can effectively alleviate Cx43 degrading induced by acute myocardial infarction ,the mechanism of this effect is associated with resisting oxidative stress .

Objective To study the effect of Zhibitai capsule on blood lipids,blood glucose and omentin in hyperlipidemic rats.Methods Thirty SPF male rats were randomly divided into control group, model group and Zhibitai group.The control group was fed with common diet,while the rest rats were fed with high－fat diet.After the model was successfully established,the Zhibitai group was orally administered 8mg/kg Zhibitai capsule powder twice daily,the rats in the control group and the model group were given the same amount of normal saline respectively. After 4 weeks,the serum levels of total cholesterol (TC),triglyceride (TG),high density lipoprotein (HDL－C),low density lipoprotein (LDL－C),blood glucose and omentin were evaluated.Results Compared with the model group, the serum levels of TC[(3.97 ± 0.62) mmol/L vs.(6.33 ± 1.10) mmol/L,t =5.910,P <0.01],TG[(1.51 ± 0.47)mmol/L vs.(2.18 ± 0.64)mmol/L,t=2.472,P<0.05]and LDL－C[(0.30 ± 0.04)mmol/L vs.(0.48 ± 0.16) mmol/L, t =3.451, P <0.01)] of the Zhibitai group were significantly decreased,the HDL －C level was significantly increased[(1.35 ± 0.28) mmol/L vs.(1.06 ± 0.31) mmol/L,t =2.195,P <0.05],blood glucose decreased significantly[(5.04 ± 0.82)mmol/L vs.(6.43 ± 1.10)mmol/L,t=3.204,P<0.01],and the concentration of omentin was significantly increased[(68.59 ± 24.82) ng/L vs.(46.86 ± 20.12) ng/L,t =2.151,P <0.05].

Atherosclerosis(AS)is the common pathological basis of ischemic cardiovascular diseases,and its formation mechanism is complex.Western medical treatment has problems such as a long cycle and a high relapse rate.Ethnic medicine is an important part of traditional medicine,which has unique efficacy in treating cardiovascular diseases.Studies have shown that the Mongolian medicine Eldon-Uriel regulates blood lipids and improves blood rheology in the treatment of AS.This paper aims to pro-vide new ideas for the prevention and treatment of AS by collecting,organizing,and summarizing the relevant literature on Eldon-Uriel and introducing its unique concept,mechanism of action,and clinical studies in the treatment of AS.
