Ne content on the AD group was greater than that of your cascular Sirt2-IN-1 Solvent dementia group (Figure ).Discussion Homocysteine is definitely an intermediate product of methionine metabolism.Lots of studies showed that homocysteine was an independent danger element for coronary artery disease, cerebrovascular illness, peripheral vascular illness and other people.Some research held that hyperhomocysteinemia played a part in the occurrence and development of AD.Research have shown that high homocysteine brought on cognitive function and resulted in AD, which may possibly be associated with biochemical damage brought on by oxidative stress .High levels of homocysteine can markedly increase the content of oxygen absolutely free radicals and promote the formation of nitric oxide.Higher levels of nitric oxide can become neurotoxic substances .Oxygen no cost radicals can promote schizolysis of APP ( amyloid protein precursor) and formation of A amyloid protein, as a result growing the generation and deposition of A, which is the primary pathological alter in AD.Our study result showed that when the AD group was compared with all the standard control group, the MMSE score was reduce and also the homocysteine content material larger, using a statistically substantial difference between the two groups (P ).When the AD group was compared with the vascular dementia group, the MMSE scores weren’t substantially diverse between the two groups (P ); the homocysteine content of the AD group was lower than that of the vascular dementia group, using a statistically important difference (P ).In accordance with the extensive outcome in the above documents, it was usually considered that the MMSE score and homocysteine content may very well be employed as one particular on the PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21593114 indicators to distinguish AD and typical elderly subjects, and the homocysteine content material as 1 of the indicators to distinguish AD and vascular dementia.The outcome of our metaanalysis was limited within the following aspects firstly, although our study incorporated publications, we didn’t make stratified analysis on gender and diverse ages, so we couldn’t see a lot more detailed outcome; secondly, there existed choice bias that could not be excluded along with the influence of confounding factors that could not be determined; furthermore, there existed methodological defects in publications included in our metaanalysis, which include not clearly explaining random technique, blinding technique and other individuals, which affected our evaluation final results.It truly is held in evidencebased medicine that the proof obtained from randomized controlled clinical trials has the strongest authenticity and reliability; and the comprehensive conclusion is far more convincing from systematic evaluation on a number of RCT and metaanalysis, as compared with single RCT.Most research included in our evaluation are retrospective casecontrol studies and usually do not belong towards the RCT category within the strict sense, which straight affects the demonstration strength of our metaanalysis outcome.Within the future, when creating systematic evaluation on multicenter RCT studies among elderly folks, we are hopeful to obtain conclusive evidence around the relationship in cognitive function involving homocysteine and AD, then offering directions to clinical practice and creating clinical intervention method much more rational.Disclosure of conflict of interest None.Address correspondence to Dr.Yuan Zhong, Division of Geriatrics, Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University, Yishan Road, Shanghai , China.Tel ; Email [email protected]
