Chinese Journal of Applied Physiology 2015;31(2):123-126
OBJECTIVETo observe the effect of Oxymatrine on left cardiac function and ventricular remodeling in rabbits after acute myocardial infarction.
METHODSLigation of the left anterior descending artery was adopted to establish acute myocardial infarction model, forty eight rabbits were randomized into the sham operation group, model group and Oxymatrine group. Eight models were successfully established in each group. the sham operation group and model group were given conventional feed. Oxymatrine were gavage administration 0.5 ml/100 g, once a day, lasted for 4 weeks. Respectively in postoperative week, and three weeks, to observe the Oxymatrine on cardiac output (CO), left ventricular end systolic pressure (LVESP), left ventricular end-diastolic pressure (LVEDP), left indoor pressure change rate peak (dp/dtmax)), and left ventricular cavity internal diameter (D), ventricular weight index (VWI), ventricular weight (VW).
RESULTSLeft ventricular anterior wall was from red to deep purple, electrocardiogram showed II guide ST-segment camber up ≥ 0.25 mv. Postoperative week in Oxymatrine group compared with model group, LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P < 0.01); After three weeks in Oxymatrine group compared with model group, VW, VWI decreased (P < 0.05), D significantly reduced (P < 0.01); LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P <0.01); dp/dt(max), CO increased (P < 0.05).

China Pharmacy 2016;27(26):3605-3608,3609
OBJECTIVE:To evaluate the economical efficiency of alogliptin for type 2 diabetes and provide clinical evi-dence for related researches. METHODS:Retrieved from Cochrane Library,Pubmed,EMBase,CNKI,VIP,Wanfang,CBM database up from the start of the database to Mar.,2014,RCTs about alogliptin combined with traditional antidiabetic agents regimen vs. traditional antidiabetic agents regimen in the treatment of type 2 diabetes mellitus were included. Based on the sec-ondary analysis method of literatures,Effectiveness indexes and treatment course were extracted from the literatures,from the perspective of patients,and daily treatment cost was used to calculate the cost;cost-effectiveness analysis was adopted to evalu-ate the economical efficiency of alogliptin combined with traditional antidiabetic agents regimen vs. traditional antidiabetic agents regimen. RESULTS and CONCLUSIONS:6 literatures which met inclusion criteria were included. When alogliptin com-bined with metformin treatment lasted for 12 weeks,the decrease value of HbA1c as effect index showed poor cost-effective-ness;when treatment course increased to 26 weeks,the rate of qualified HbA1c as effect index showed poor cost-effectiveness. When the price of alogliptin decreased by 10% or the effects of trial group was the upper limit of 95%CI,the cost-effective-ness was superior to metformin regimen group. 12 weeks of alogliptin combined with pioglitazone treatment showed better cost-effectiveness than pioglitazone alone using the decrease value of HbA1c as effect;when treatment course increased to 26 weeks,the treatment showed poor cost-effectiveness;when treatment conrse increased to 26 weeks,using the rate of qualified HbA1c as effect indes,the results of sensitirity analysis showed that cost-effectiveness of trial group was better than that of pio-glitazone alone group as the apper limit of 95% CI. When alogliptin combined voglibose treatment lasted for 12 weeks,the de-crease value of HbA1c as effect index showed superior cost-effectiveness to voglibose regimen group. It is suggested to develop alogliptin pharmacoeconomics research based on RCTs and pharmacoeconomics research about improving diabetes patients’ long-term living quality.

The HSS found in the cytosol of new-born calf liver was heat-stable and it promoted the DNA-synthesis of guinea-pig liver cells (P/o:5.72),HSS was also found in the cytosol of new-born rat livers,and its most effective concentration to promote incorporation of H2-TdR into DNA of guinea-pig liver cells was about 0.05mg/ml.This activity was reduced with both the increase and decrease of cytosol content,and the reason was not clear.It was proved with SDS-PAGE that the molecular weight of the active component was about 14000 and 23000 daltons.The cytosol from control rat livers showed no HSS activity and also no component measuring 23000 daltons.It needs further identification that the 23000 daltons protein is the active component in the cytosol of new-born calf and rat livers and the partially hepatectomized rat livers,but not in the cytosol of control rat livers.This finding indicateds that the livers of new-born calf and rat contain highly active HSS and are a valuable resource of HSS
