Objective: To establish a quantitative analysis of multi-components by single marker ( QAMS ) for determining the three alkaloids in Jinji capsules. Methods:With the typical composition palmatine as the internal standard, the relative correction fac-tor ( RCF) between the palmatine and berberine or jateorhizine was respectively established, and the content of berberine and jateorhiz-ine was respectively calculated by QAMS. An external standard method was used to determine the three alkaloids, and the calculated values were compared with the estimated values by Pearson correlation coefficient. Results:There was no significant difference between the calculated values in QAMS and the estimated values in the external standard method, and the RCF was credible. Conclusion:The new method is feasible and accurate to evaluate the contents of the three alkaloids in Jinji capsules.

Objective To evalute Qiliqiangxin capsule for improving cardiac function and identifiy Qiliqiangxin capsule for directing cytoprotective effects against apoptosis of cardiomyocytes. Methods Sprague Dawley (SD) rats were tested as subjects and the model rats were built by anterior descending coronary deligation, then the survival rats were devided into 6 groups randomly:sham-operated group(sham,n=8),fed with normal saline of same volume instead;control group(control,n=7),fed with normal saline of same volume instead;Qiliqiangxin great dosage group(great,n=9),Qiliqiangxin 1.2g/(kg?d) treatment;Qiliqiangxin medium dosage group(medium,n=9),Qiliqiangxin 0.6g/(kg?d) treatment;Qiliqiangxin small dosage group(small,n=8 rats),Qiliqiangxin 0.3g/(kg?d) treatment;the captopril group(captopril,n=9),captopril 25mg/(kg?d) treatment.24 hours later,rats in sham operated group and model group were given normal saline,rats in treating group were given Qiliqiangxin,rats in the contrasting group were given captopril.After being treated for 4 weeks, all rats′ heart function was measruated by right flank arteria carotis communis arterial cannula.The left ventricle mass index was calculated and the expression of protein caspase-3 was tested by immunohistochemical method and Westernblot. Results Compared with control group, Qiliqiangxin capsule could reduce effectively BW,HMI,LVMI,increase LVEDP and LVSP,+dp/dtmax and -dp/dtmax.Immunohistochemical analysis and Westernblot analysis showed that adminstration of Qiliqiangxin significantly inhibited caspase-3 expressions in myocardial cells in a dose-dependent manner.Conclusion Qiliqiangxin significantly improved the CHF rat′s cardiac function and reduced the left ventricle mass index and heart mass index 4 weeks after being treated with relative high dose Qiliqiangxin. It might be partially attributed to the suppression of caspase-3 expressions.

Objective To evaluate and eliminate the potential bias between data obtained from dry and liquid biochemical assays,making data obtained by different assays matchable.Methods Bias estimation was performed based on document EP9-A2.Simple data comparison and methodology validation were performed after the experiment methods were modified with the estimated correction factors and interception.All the collected data were analyzed by EXCEL2007 software.Results The predicted bias of 4 of the 10 compared items exceeded their corresponding acceptable bias.After being adjusted by the coefficient and interception obtained from linear regression analysis,the four bias was improved and was within the acceptable range.The results of simple data comparison further confirmed this comparability.Conclusion Based on EP9-A2,we have established a protocol to obtain a consistency of data from different biochemical analyzers,which makes it possible that the detection results of the same patient from different detection systems can be used directly.The protocol has been approved by the experts during the medicinal laboratory accreditation of ISO15189.

Objective To evaluate the significance of coronary calcification and stenosis in elderly hypertensive patients by 16-row multi-sliced computed tomography (MSCT) and its association with peripheral arterial atherosclerosis and other target organ damages. Methods Sixty-four patients with hypertension (n=50) 76.1?6.5 years and normotensions (n=14) 73.4?6.8 years were enrolled. All patients underwent coronary calcification scan by MSCT and the coronary calcification score(CCS) was calculated as AJ130 and Volume. Fourty-four patients in the hypertensive group were subjected to MSCT enhanced scan for evaluation of coronary stenosis. Intima media thickness (IMT), atherosclerotic and calcified plaques in carotid and femoral arteries and ankle-brachial index (ABI) carotid and femoral arteries were measured by echosonography and echocardiography; Fasting plasma blood glucose, blood lipid series, insulin, HOMA-IR, hsCRP and morning urine albumin were determined. Results (1) Both AJ130 and Volume of left anterior descending artery(LAD), left circumflex artery(LCX) and the total calcification score were higher in the hypertensive group than those in the control group (P

The effects of melittin on the activities of Na+-K+-ATPase and glucose-6-phosphate dehydrogenase (G-6-PD) which are on the membrane of red blood cell (RBC) are chosen as the index of this study. The possible target sites of these effects through enzyme activity determination by spectrophotometry are investigated, and the hemolytic process and the activity change of these two types of enzymes on the RBC membrane are discussed. The results show that the main mode of melittin inhibition to the activity of enzymes on the RBC membrane is the coexistence of adhesion/insertion form and free-state form, and the effect of the former is more stronger than the latter. The K+ binding site of Na+-K+-ATPase is one of the target sites of melittin. The membrane-insertion process of melittin synchronizes with the action of melittin on this enzyme. Melittin slowly inhibits the catalysis of G-6-PD through the action on G-6-P and NADP, and the extent in which melittin forms tetramers isclosely related to the enzyme activity. EDTA inhibits the aggregation of melittin, and interferes with its action on G-6-P. The biochemical mechanisms of melittin effects on the substrate G-6-P and the coenzyme NADP are similar, and the inhibition of melittin is not related to the structure of G-6-PD.
