ABSTRACT
OBJECTIVE：To rapidly evaluate the effectiveness ，safety and economy of evolocumab in the treatment of hypercholesterolemia so as to provide evidence-based reference for clinical drug selection and decision. METHODS ：Retrieved from PubMed，Cochrane Library ，CNKI，Wanfang database and HTA relative official website ，HTA reports ，systematic evaluation/ Meta-analysis and pharmacoeconomic studies about evolocumab alone or combined with standard plan versus standard plan or placebo or ezetimibe in the treatment of hypercholesterolemia were collected during the inception to Jan. 2020. Based on literature screening and data extraction ，HTA checklist ，system evaluation measurement tool AMSTAR- 2 scale，comprehensive healthy economic evaluation report standard scale were used to evaluate the quality of included HTA reports ，systematic evaluation/ Meta-analysis and pharmacoeconomic literatures. Quantitative description was performed for effectiveness and safety results ，and qualitative description was performed for economic evaluation results. RESULTS ：A total of 13 literatures were included ，involving 6 Meta-analysis and 7 economic studies. The quality of Meta-analysis literatures was low ，and the quality of economic research was good. In terms of effectiveness ，compared with placebo or ezetimibe ，evolocumab significantly reduced the levels of LDL-C ，TC， TG and VLDL-C ，the incidence of cardiovascular events ，myocardial infarction ，coronary ischemia and stroke ，while increased the level of HDL-C （P＜0.05）. There was no statisti cal significance in the risk of hospitalizatio n，cardiac mortality or cardiovascular disease mortality in patients with unstable angina pectoris between placebo and evolocumab （P＞0.05）. In terms ofsafety，there was no significant difference in the incidence of 6237545。E-mail：zhangxu1130@163.com any adverse events ，any treatment emergency adverse events and back pain ，musculoskeletal and connective tissue diseases between evolocumab and placebo （P＞0.05）. In terms of economy，additional use of evolocumab ，based on standard plan ，had a cost-effectiveness advantage for patients with high-risk atherosclerotic cardiovascular disease （ASCVD）whose blood lipids were still not up to standard. CONCLUSIONS ：Evolocumab has good effectiveness and safety in the treatment of hypercholesterolemia. For high-risk patients with ASCVD whose blood lipids are still not up to standard after standard plan ，evolocumab has certain economy and can be used as an alternative.
ABSTRACT
OBJECTIVE:To study the antitumor effect of phellinus linteus polysaccharide on sarcoma S180 cells in vivo and in vitro. METHODS:Sarcoma S180 cells in logarithmic growth period were selected,adding into 0(blank control),2,4,8 mg/mL phellinus linteus polysaccharide solution and respectively culturing for 12,24,36,48 h. The in vitro proliferation inhibition rate of cells was determined by MTT method;its apoptotic morphology was observed by fluorescence staining and cell apoptosis rate was detected by flow cytometry. S180 tumor-bearing mice models were established and randomly divided into control group,phellinus linteus polysaccharide high-dose,medium-dose,low-dose groups(400,200,100 mg/kg),10 in each group. Model mice were in-tragastrically administrated related medicined,once a day,for 12 d. Mice were executed after 24 h of last administration,tumor weight was determined,tumor inhibition rate was calculated. Immunohistochemistry was conducted to detect the tumor suppressor gene PTEN and oncogene C-myc protein expressions in tumor tissue. RESULTS:Compared with blank control group,phellinus linteus polysaccharide can increase the proliferation inhibition rate of S180 cells and induce the increase of apoptosis rate(P<0.05 or P<0.01),showing a concentration-time manner. Compared with control group,the tumor inhibition rates in phellinus linteus polysaccharide groups were obviously increased (P<0.01),PTEN protein expressions were strengthened (P<0.05 or P<0.01) and C-myc protein expressions were weakened (P<0.05). CONCLUSIONS:Phellinus linteus polysaccharide shows antitumor ef-fect in vivo and in vitro,which can up-regulate the PTEN,down-regulate C-myc protein expressions.
ABSTRACT
OBJECTIVE:To improve medication compliance of patients with nonvalvular atrial fibrillation (NVAF) to warfarin and its influential factors,and to provide reference for guaranteeing the safety and effectiveness of therapy.METHODS:A questionnaire survey was conducted among NVAF patients receiving warfarin anticoagulation in our hospital,MMAS-8 and WRKS were adopted to evaluate medication compliance of patients to warfarin and the understanding of patients to the knowledge of anticoagulation treatment.Related influential factors for medication compliance of patients to warfarin were investigated by x2 test,t test and Logistic multiple regression analysis.RESULTS:Totally 129 questionnaires were sent out,and 112 were effectively received with effective recovery of 86.82％.The mean score of MMAS was (6.54 ± 1.61),and 42.86％ patients had good medication compliance.The mean score of WRKS was (7.95 ± 1.65);that of patients with good medication compliance was (9.31 ± 0.83),and that of patients with poor medication compliance was (6.92 ± 1.34).Single factor analysis showed that there was statistical significance in gender,age,occupation,educational level,the number of compliance,WRKS score between patients with good medication compliance and those with poor medication compliance (P＜0.05).Multivariate Logistic regression analysis showed that WRKS score,gender,educational level and the number of compliance were significantly correlated with medication compliance (P＜0.05).CONCLUSIONS:Poor medication compliance of NVAF patients to warfarin is related to multiple influential factors.The knowledge of warfarin anticoagulation is an important factor.
