Objective To investigate the protective effect of Schizandrae Lignanoid (SCL) on myocardial ischemia reperfusion injury in hyperlipidemic rats and its mechanisms and provide theoretical basis and experiment foundation for treatment of myocardial ischemia complicated with hyperlipidemic disease with SCL in the future. Methods After hyperlipidemic rat models were set up by oral administration of high lipid emulsion,the rats were divided into seven groups: control group,sham group,model group,SCL 60,20,5 mg?kg-1 groups and 200 mg?kg-1 CDT group.After reperfusion,the blood samples taken from the ventricles were assayed for blood lipid;MPO activities of ischemic myocardium were measured;Infarct area of left ventricles was measured by Evens blue-TTC staining,and myocardial pathological changes were also observed.Results Compared with model group, the myocardial infarct area/ventricle area ratios and MPO activities in SCL 60,20,5 mg?kg-1 groups decreased (P

Objective To explore the oxidative stress pathogenesis of Parkinson's disease(PD) induced by paraquat in substantia nigra of mice. Methods The model of PD was established by oral administration of paraquat to mice.The spectrophotometry was used to determine the activities of superoxide dismutase(SOD) and glutathione peroxidase(GSH-PX) and the content of malondialdehyde(MDA) in substantia nigra.At the same time,number of tyrosine hydroxylase(TH) positive neurons in substantia nigra of mice was estimated by immunohistochemistry. Results The activities of SOD and GSH-PX were significantly decreased,and the content of MDA was increased in paraquat-treated mice compared to that of mice treated by saline taken orally(P

In this article we analyzed the current development of moxibustion treating rheumatoid arthritis from the usefulness, advancement, synergistic effect as well as the variance between different kind of moxibustion. We concluded that moxibustion was an effective intervention for treating RA, and the methods used in moxibustion were searched in clinic. But the clinical tralls has a long way to go, we should pay more attention to the critical issues while in the use of moxibustion.

Aim To study clinical efficacy of valsartan,in comparison with amlodipine, in hypertentive patients with left ventricular hypertrophy. Methods 65 hypertentive patients with left ventricular hypertrophy is divided into two groups, with 33 cases in valsartan group and 32 cases in amlodipine group Valsartan 80～160mg and amlodipine 5～ 10 mg were taken by the patients in the two groups for 6 months respectively. 24 h ambulatory blood pressure monitoring ( 24 h ABPM) and color echocardiography were performed in the two groups before and after treatment. Results The parameters of 24 h ABPM ( 24 h SBP? 24 h DBP?dSBP?dDBP?nSBP?nDBP) and color echocardiography (IVST?PWT?LVMI)after treatment in the two groups were significant decreased compared with those before treatment respectively (P0.05). Conclusion Valsartan can lower significantly the blood pressure level and make left ventricular hypertrophy remarkably dispelled in hypertensive patients with left ventricular hypertrophy and has the effect similar to that of amlodipine.

As urine flow dynamic test is widely used in clinical,merge detrusor dysfunction of benign prostatic hyperplasia treatment research also more and more.For normal detrusor contraction force and slight damage (Pdet ＞ 20 cmH2O) of the operative efficacy of BPH patients have reached a consensus of scholars both at home and abroad.For merger severely impaired detrusor contraction force (Pdet 0-20 cmH2O) at odds with the treatment of benign prostatic hyperplasia patients,in combination with related literature,now just urethral catheterization or colostomy,the transurethral resection of the prostate in the same period the bladder again after colostomy,the comprehensive treatment evaluation IⅡ transurethral resection of the prostate surgery and review these main treatment.

Objective: To investigate the hydrolysis conversion rate of alcohol amine-diterpene alkaloids from aconitum alkaloids, hydrolyze aconitum alkaloids reference substance, calculate the amount of alcohol amine-diterpene alkaloids in the hydrolysis solution by the hydrolysis conversion rate, which is used as the amount of alcohol amine-diterpene alkaloids reference substance, and establish a content determination method for aconine, hypaconitine and aconine in Aconiti radix cocta.Methods: Through controlling the hydrolysis conditions of aconitine, hypaconitine and mesaconitine, aconine, hypaconitine and aconine were obtained.The determination was performed on an Agilent ZORBAX Extend-C18 RRHT(2.1 mm×50 mm,1.8 μm) column with the mobile phase consisting of methanol(A)-water(B containing 0.1% formic acid and 2.5 mmol·L-1 ammonium acetate) with gradient elution by HPLC-QTOF-MS.The flow rate was 0.21 ml·min-1.The column temperature was 30 ℃.MS instrument was equipped with an ESI+ ion source.Results: Under the hydrolysis conditions of this study, the conversion rate of aconine from aconitine was 99.64%;the conversion rate of hypaconitine from hypaconine was 99.94%;the conversion rate of mesaconitine from mesaconine was 99.57%.The HPLC-QTOF-MS methodological investigation showed the 3 kinds of alcohol amine-diterpene alkaloids were with good linearity (r>0.999 1).The RSD of the precision, repeatability and stability tests were less than 5%.The average recoveries were within the range of 99.43%-100.10%.Conclusion: The validated method is simple, specific, reliable and reproducible.In the absence of reference substance, it can be used for the quality control of the herbs of Aconitum L.species.

Objective:To develop a method of quantitative analysis of multi-components by single marker( QAMS) for nine kinds of alkaloids in Xiaohuoluo pills. Methods: An HPLC-QTOF-MS method with an Agilent ZORBAX Extend-C18 RRHT(2. 1 mm × 50 mm,1. 8 μm) column was applied. The flow rate was 0. 21 ml·min-1 . The column temperature was 30 ℃. The mobile phase was methanol (A)-water (B;containing 0. 1％ formic acid and 2. 5 mmol·L-1 ammonium acetate) with gradient elution. The aconitine was used as the internal standard, and the relative correction factor ( RCFs) of hypaconitine, mesaconitine, benzoylaconine, benzoyl-hypaconine, benzoylmesaconine, aconine, hypaconine and mesaconine was respectively established, and the reproducibility inspection on the RCF was performed. The contents of the other 8 kinds of aconitum alkaloids were calculated according to the RCF. At the same time, an external standard method ( ESM) was performed for the content determination of the nine alkaloids. The results of the two methods were compared. The feasibility and accuracy of the QAMS method were verified. Results:Within a certain range,the RCF of hypacontine,mesacontine, benzoylaconine, benzoylhypaconine, benzoyl mesaconine, aconine, hypaconine and mesaconine to aconitine was 1. 736,1. 979,1. 0471,0. 9242,1. 2901,1. 3078,1. 2859,and 1. 0948,respectively. The QAMS method was established for determi-ning alkaloids. There were no significant differences between the results of the QAMS method and those of the external standard method ( ESM) . Conclusion:With the validation of methodology, the method established in our study can be used for the content determina-tion of aconitine, hypaconitine, mesaconitine, benzoylaconine, benzoylhypaconine, benzoylmesaconine, aconine, hypaconine and mesaconine in xiaohuoluo pills.
