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).

CONCLUSIONAfter acute myocardial infarction in rabbit Oxymatrine can improve the left ventricular reconstruction parameters, increase cardiac output, and improve cardiac function.

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.

Objective To investigate the relationship between Oxfordshire community stroke project(OCSP) classification and imaging classification in acute cerebral infarction. Methods Two hundred and thirty-six patients with acute cerebral infarction were retrospectively evaluated with OCSP classification and imaging characteristics. Results According to OCSP classification,of all the 236 patients with acute cerebral infarction,28(11.9%) experienced total anterior circulation infarction(TACI),71(30.1%) partial anterior circulation infarction(PACI),94(39.8%) lacunar infarction(LACI),and 43(18.2%) posterior circulation infarction(POCI).The consistency was found in 171 cases(72.5%) between the OCSP classification and imaging classification,with the accuracy of 76%(25/33) for TACI,81%(34/42) for PACI,71%(81/114) for LACI and 66%(31/47) for POCI. Conclusion OCSP classification can predict the location and size of cerebral infarction with a high accuracy,and is well consisted with the imaging findings.

Total 406 community residents entered in fitness improvement program with “management by objectives model of health promotion” from 2009 to 2011.The fitness status was monitored by Xuhui Physical Constitution Center before and after entering the program.The results showed that the level of fitness assessment,the composite score,lung capacity and reaction time were improved with the years (P ＜ 0.01) ; the step index and sitting-and-reach test in 2010 was better than those in 2009(P ＜ 0.01) ; the grip strength in 2010 and 2011 was better than that in 2009 (P ＜ 0.01); the test of single leg-standing with closing eyes in 2011 was better than that in 2009(P ＜ 0.05).There was no difference in body mass index before and after program (P ＞ 0.05).The results indicate that physical fitness and overall health can be improved by management by objectives model for health promotion.

Objective To compare the clinical efficacy of percutaneous kyphoplasty (PKP) by balloon dilatation between unipedicular and bilateral pedicle approach for the treatment of osteoporotic vertebral compression fractures (OVCF). Methods From January 2012 to March 2014, 56 patients with single-level or double- level OVCF were randomly divided into two groups. 29 patients with 33 vertebral bodies were performed by PKP through unipedicular approach and 27 patients with 31 vertebral bodies through bipedicular approach , used PMMA bone cement filling vertebral. The clinical data of patients were prospectively analyzed and the clinical efficacy was compared between two groups. Results The VAS scores, Beck value, Cobb angle and ODI scores after operation improved in both groups (P < 0.01),but there were no significant difference between two groups(P > 0.05). The operative time, X-ray exposure time and volume of bone cement in unilateral group were less than that of bilateral group(P < 0.01). There were no significant difference in the incidence of bone cement leakage ,the pain relief and the incidence of complications between two groups (P > 0.05). Conclusion Both unipedicular and biopedicular PKP are significant improvement for the OVCF, vertebral strengthen showed similar efficacy, but the former has easy operation procedure, can shorten operative time and reduce X-ray exposure time and less volume of bone cement.

Objective To compare proximal femoral nail(PFN)introduction by percutaneous K-wire through a small incision with conventional PFN introduction protocol in the treatment of intertrochanteric fractures. Methods From January 2004 to March 2005,51 patients with intertrochanteric fractures were randomly dis- tributed into a minimally invasive treatment group(group MI)and a conventional treatment group(group C).All the fractures were closely reduced.In group MI a K-wire was percutaneously inserted through the tip of the greater troehanter into the center of medullary canal of the pruximal femur before the PFN was inserted under the guidance of K-wire through a small incision made along the K-wire while in group C the PFN was introduced according to the conventional procedure.The operation time,intra-operative blood loss,length of incision,X-ray exposure,duration of in-patient stay and time of bone union in both groups were recorded and compared.Results The mean oper- ation time,mean intraoperative blood loss and mean length of incisions in group MI were 77.20 min,104.20 mL and 5.12 cm respectively and significantly lower than those in group C(P＜0.01).The X-ray exposure and the reduction time in group MI lasted longer than in group C(P＜0.01).The mean time of bone union and in-patient stay in both groups were nearly equal(P＞0.05).At the latest tollow-up,all the fractures united in both groups without nonuuion or delayed union.Conclusion Compared with the conventional protocol,introduction of PFN by a pereutaneuus K-wire inserted into the central medullary canal of the proximal femur is much more minimally in- vasive and effective.
