摘要
Objective:To evaluate the efficacy and safety of Shen Zhi Ling oral liquid(SZL)alone or combined with basic treatment in treating Alzheimer's Disease(AD).Methods:Databases including PubMed,the Cochrane Library,Embase,Web of science,China National Knowledge Infrastructure(CNKI),Wanfang Database and the Chinese Science and Technology Journal Database(VIP)were searched from inception to September 20,2020 to collect relevant randomized controlled trials(RCTs)comparing SZL with other nootropic drugs for AD.The primary clinical outcomes were scores of the Mini Mental State Examination(MMSE)and the Activities of Daily Living(ADL)during treatment.The secondary outcomes of our study included other neuropsychological scale scores including Rapid Verbal Retrieve(RVR),Digit Span(DS),Fuld Object-Memory Evaluation(FOM)and adverse events or reactions.Two authors searched and screened the literature independently,then extracted the data and evaluated the methodological quality by using the handbook of Cochrane Collaboration,and analyzed the data via the Review Manager 5.3 software.Results:In total,we included four studies,covering 217 participants.All studies were in a low methodological quality.The result of MMSE score,ADL score,RVR score,DS score and FOM score in the meta-analysis showed that no statistically significant difference(P>0.05)between the treatment groups and control groups,and the statistical heterogeneity of all meta-analyses was small(I2<50%).SZL was indicated no better than other nootropic drugs.Among the included studies,no study described adverse events.Conclusions:Considering the low quality of the included trials and the different levels of AD patients,we are unable to come to any conclusion about the efficacy and safety of SZL compared with other nootropic drugs.Moreover,we still need rigorously designed,multi-center,large-scale trials to further confirm the efficacy and safety of SZL.
