All of the correlation coefficient similarities of different TCMs are higher than 0.952, and the included angle cosines are all higher than 0.962. So, both the conelation coefficient and included angle cosine similarities are unable to be used as the criteria for quantitatively evaluating the similarities of NLC fingerprints of TCMs. Although all of the Euclidean distance similarities of Berry Liquorices from four producing areas are less than 73, those of the other eight TCMs are all more than 180. The Euclidean distance cannot reflect the relative magnitudes of the feature differences in the NLC fingerprints very correctly. The systemic similarity method is the best among the four ones. All of the systemic similarities of Berry Liquorices from the four producing areas are higher than 0.962, while those of the other eight TCMs are all lower than 0.805, and the systemic similarity can reflect the differences between samples most faithfully, and can be used as a quantitative one evaluating the similarities of NLC fingerprints of TCMs, by which TCM could be distinguished and evaluated quickly, simply and exactly.展开更多

An integrative and multi-targeted strategy is increasingly appreciated to effectively combat this devastating disease. Traditional Chinese medicine(TCM) has been widely used for treatment of dementia, and thus the advantages of the potential therapeutic features of TCM treatment and associated mechanisms should be well taken. The Amnesia Remedy Formula(ARF) was invented by one of the most influential Master of TCM SUN Si-miao, who lived for about 100 year old. The aim of this research is to characterize the time course changes of the cognitive behaviors post a ARF, and the mechanism underlying the effects, focusing on PKA-centered signaling for both enhancement of neural plasticity and clearance of the phosphorylated Tau. RESULTS We tested the efficacy of ARF on two animal models of AD, and examine the central role of PKA signaling in the enhancement of neural plasticity via PKA/CREB/BDNF pathway as well as clearance of toxic p Tau via PKA/GSK3β/p Tau pathway. In the scopolamine model, ARF effectively reversed the memory in Morris water maze(MWM) test, with some features superior to anti-AD drug donepezil. In a battery test of MWM, novel object recognition or T maze in 5-month-old senescenceaccelerated mouse prone 8(SAMP8) strain mice, two weeks of administration of ARF showed overall better improvement in memory loss than donepezil, and the effect lasted for at least 1 week after termination of administration of the formula. ARF increased expression of PKA/CREB/BDNF and synaptic proteins PSD95 expression, as well as enhanced Ser9 phosphorylation of GSK3β, thus reduced p Tau in the hippocampus. Blockade of PKA signaling blunted the anti-AD-like effect of ARF, with reversal of CREB/BDNF signaling. Transcriptomic analysis indicated some changes of novel molecules along this pathway may be part of the pathological and therapeutic mechanism, which warrants further investigation. CONCLUSION ARF may display some advantageous features in treating AD with early onset, via multi-targeted manner including enhancement of neural plasticity and reduction in Tau toxicity.展开更多

文摘Recent fast advance in biomedical research at the“omic”levels has led to an explosion of big data for the understanding the molecular makeup of diseases,which have revealed the intimate unmatched relationships between the genomic variabilities and the current organ-or system-based definition and classification of disease in Western medi⁃cine.The major challenges in the effort to establish and develop precision medicine are how diseases should be defined and classified in an integrated systemic or omic scale and also on an individualized basis.The phenomics approach to the understanding of diseases will allow the transition from focused phenotype/genotype studies to a systemic largescale phenome and genome,proteome,metabolome approach and the identification of a systemically integrated setof biomarkers for diagnosis and prognosis of disease phenome(or Zhenghou).Phenome-wide associated study(PheWAS)may soon lead the field of medical research and provide insightful and novel clues for redefinition of the disease phenome and its clinical classifications and personalized treatment and ultimately precision medicine.Pharma⁃cophenomics is to characterize the phenomes of drug response and also to identify the corresponding therapeutic targets at the level of systems biology.As a complement of pharmacogenomics/proteomics/metabolomics,pharmacoph⁃enomics offers a suite of new technologies and platforms for the transition from focused phenotype-genotype study to a systematic phenome-genome approach and refine drug research with systematically-defined drug response and thera⁃peutic targets.Therefore,pharmacophenomics will provide a new paradigm for the study of drug response including effects and toxicities at the level of systems biology and will identify the corresponding therapeutic targets and principles for combination treatment and prevention of disease using Fangji or Fufang that takes into account individual variability in genes,environment,and lifestyle for each person.

文摘OBJECTIVE Currently, almost all chemical compounds or biological reagents to reverse or slow down the AD process have failed in clinical trials. An integrative and multi-targeted strategy is increasingly appreciated to effectively combat this devastating disease. Traditional Chinese medicine(TCM) has been widely used for treatment of dementia, and thus the advantages of the potential therapeutic features of TCM treatment and associated mechanisms should be well taken. The Amnesia Remedy Formula(ARF) was invented by one of the most influential Master of TCM SUN Si-miao, who lived for about 100 year old. The aim of this research is to characterize the time course changes of the cognitive behaviors post a ARF, and the mechanism underlying the effects, focusing on PKA-centered signaling for both enhancement of neural plasticity and clearance of the phosphorylated Tau. RESULTS We tested the efficacy of ARF on two animal models of AD, and examine the central role of PKA signaling in the enhancement of neural plasticity via PKA/CREB/BDNF pathway as well as clearance of toxic p Tau via PKA/GSK3β/p Tau pathway. In the scopolamine model, ARF effectively reversed the memory in Morris water maze(MWM) test, with some features superior to anti-AD drug donepezil. In a battery test of MWM, novel object recognition or T maze in 5-month-old senescenceaccelerated mouse prone 8(SAMP8) strain mice, two weeks of administration of ARF showed overall better improvement in memory loss than donepezil, and the effect lasted for at least 1 week after termination of administration of the formula. ARF increased expression of PKA/CREB/BDNF and synaptic proteins PSD95 expression, as well as enhanced Ser9 phosphorylation of GSK3β, thus reduced p Tau in the hippocampus. Blockade of PKA signaling blunted the anti-AD-like effect of ARF, with reversal of CREB/BDNF signaling. Transcriptomic analysis indicated some changes of novel molecules along this pathway may be part of the pathological and therapeutic mechanism, which warrants further investigation. CONCLUSION ARF may display some advantageous features in treating AD with early onset, via multi-targeted manner including enhancement of neural plasticity and reduction in Tau toxicity.
文摘OBJECTIVE To systematically review the clinical efficacy and safety on TCHMs that are used for vascular dementia(VaD).METHODS To identify studies for systematical review,electronic searches were performed through several databases-ALOIS,CNKI,CBM,Weipu,Wanfang,etc.Only randomized control trials(RCTs)or controlled clinical trials(CCTs)were included.Patients were diagnosed with VaD by diagnostic criteria(DSM,NINDS-AIREN,ICD or HIS)as well as imaging technique(CT,MRI or functional imaging,etc).Eligible TCHMs must be recognized in the Chinese Pharmacopeia or the National Essential Drug List of the People′s Republic of China.Included studies were appraised using the Cochrane Collaboration risk-of-bias criteria.Efficacy and safety outcomes were evaluated by meta-analysis.Efficacy outcomes include cognition,daily function,global performance and behaviour;safety was assessed by the number of adverse events and number of subjects experiencing adverse events.Assessment of heterogeneity,subgroup analysis and sensitivity analysis were also performed.RESULTS A total of 46 trials on 29TCHMs(3522patients)were included.45 studies were RCTs and 1was CCT.In these 45 RCTs,only 2were appraised as adequately randomised.5of 46 trials were appraised as having low risk of bias in blinding.Sample sizes were generally small ranging from 26 to 216with a median of 68.All trials were conducted in China from 1997 to 2013.All 46 studies assessed cognition using one or a combination of the following scales:MMSE(n=40 studies;3096 patients),HDS(n=22;1664 patients),ADAS-Cog(n=4;241 patients),CDT(n=1;60patients)and CCSE(n=1;26patients).Half of the studies assessed daily function using either the ADL(n=22;1743 patients)or IADL(n=2;203patients).Only 6studies measured behaviour using the FAQ(n=3;226 subjects),BBS(n=1;48patients),NPI(n=1;100subjects)or Neurological Deficits Function Scale(n=1;91patients).30 studies measured global performance.31 of 46 studies made conclusions regarding the safety of the TCHMs.Despite the problems of methodology and reporting,we can identify three TCHMs-NaoXinTong,Shenfu and Tongxinluo as having relatively stronger evidence of efficacy.There is weak evidence for the safety of TCHMs for VaD.CONCLUSION There is weak evidence for the efficacy and safety of TCHMs for VaD because of the poor methodology,short duration of follow-up and inadequate reporting.However the agents appear to be relatively free of severe short-term AEs,hence we encourage further better designed and reported trials.
