TLJN has been shown to protect primary cultured hippocampal neurons. How-ever, its mechanism of action remains unclear. In the present study, primary cultured hippocampal neurons treated with Aβ1-42 （10 μmol/L） signiifcantly increased the release of lactate dehydroge-nase, which was markedly reduced by TLJN （2 μL/mL）, speciifcally by the component geniposide （26 μmol/L）, but not ginsenoside Rg1 （2.5 μmol/L）. hTe estrogen receptor inhibitor, ICI182780 （1 μmol/L）, did not block TLJN-or geniposide-mediated decrease of lactate dehydrogenase under Aβ1-42-exposed conditions. However, the phosphatidyl inositol 3-kinase or mitogen-activated protein kinase pathway inhibitor, LY294002 （50 μmol/L） or U0126 （10 μmol/L）, respectively blo cked the decrease of lactate dehydrogenase mediated by TLJN or geniposide. hTerefore, these results suggest that the non-classical estrogen pathway （i.e., phosphatidyl inositol 3-kinase or mitogen-activated protein kinase） is involved in the neuroprotective effect of TLJN, speciifcally its component, geniposide, against Aβ1-42-mediated cell death in primary cultured hippocampal neurons.展开更多

Microinjection, reverse transcriptase-PCR （RT-PCR）, in situ hybridization and immunofluorescent staining were used in this research, and the morphology of the islet in normal zebrafish embryos, and in those treated with the siRNA specific to pdx-1 （siPDX-l） or siGFP was observed and compared. The expression of pdx-1 was detected in the stages of 1-cell, 2-cell, 4-cell, 8-cell, 16-cell, 16-hour by RT-PCT. The in situ hybridization and immunofluorescent staining results showed that siPDX-1 disturbed the formation of the islet in zebrafish embryos. Pdx-1 played multiple roles in maintaining the phenotype of the islet during embryogenesis in zebrafish.展开更多

Therapeutic principles and therapeutic methods for healing many diseases are recorded in these ancient TCM books, providing a huge number of references for modern TCM physicians on conducting diagnosis and administering treatment for different diseases. The ancient TCM books can be dated back thousands of years, and this vast knowledge is recorded in different medical books in the form of text. However, it is difficult to systematically assimilate much information in ancient TCM books. At present, many researchers are applying advanced analytical techniques to analyze the text data in the ancient TCM books. Advanced techniques that have been applied include database construction, cognitive linguistic analysis, fuzzy logic, data mining, and artificial intelligence(AI) technology. There are different characteristics in these advanced analytical techniques. In this study, we comprehensively review recent advances in these techniques applied to the study of ancient TCM books. Furthermore, as AI technology is increasingly utilized in the medical field as well as in the study of ancient TCM books, we also review the application of AI technology to the study of ancient TCM books.展开更多

Two reviewers independently conducted literature searches, screenings, data extractions, and literature bias evaluations. A meta-analysis was conducted using RevMan 5.3 and Stata 13.0 software. Results:In total, 15 studies involving 1289 patients were included. The results of the meta-analysis showed that the total effective rate of treatment in the experimental groups was higher than that of the control groups (relative risk [RR]=1.27, 95%confidence interval [CI]:1.21, 1.35, Z=8.74, P <0.00001). In the subgroup analysis, the total effective rate of oral TCM combined with Western medicine was higher than that of the control groups (RR=1.24, 95%CI:1.15, 1.33, Z=5.88, P <0.00001). The total effective rate of oral TCM with enemas combined with Western medicine was higher than that of the control group (RR=1.30, 95%CI:1.12, 1.50, Z=3.52, P=0.0004).The comparison between Western medicine alone and oral TCM combined with enteroscopy and Western medicine showed that the effective rate of enteroscopy (RR=1.18, 95%CI:1.05, 1.33, Z=2.86, P=0.004) and the symptom scores before and after treatment all improved more in the combined treatment groups than in those of the Western medicine group alone, with statistically significant differences (RR=-4.23, 95%CI:-4.93,-3.53, Z=11.84, P <0.00001). Conclusion:The integration of the TCM methods of heat clearing, dampness excreting, spleen strengthening, and stasis removing combined with Western medicine can significantly improve the cure rate of UC, and is an effective method to treat UC.展开更多

However, few studies have reported the possible differences in the effect of obesity on outcomes between older adults with metabolic abnormalities and those without metabolic abnormalities. Methods A total of 3485 older men were included from 2000 to 2014. All-cause mortality and cardiovascular mortality were obtained during a mean follow-up of five years Metabolic abnormalities were defined as having established hypertension, diabetes, or dyslipidemia and taking the disease-related medications. All participants were stratified by the presence or absence of metabolic abnormalities. Results In the non-metabolic abnormalities group, all-cause and cardiovascular deaths were lowest in overweight participants and highest in obese participants. In the metabolic abnormalities group, mortality was also lowest in overweight participants but highest in participants with normal weight. After adjustment for covariates, hazard ratios （95% CI） for all-cause death and cardiovascular death were 0.68 （0.51, 0.92） and 0.59 （0.37, 0.93）, respectively, in overweight participants with metabolic abnormalities. Furthermore, obesity was not associated with mortality risk in both groups. These findings were unchanged in stratified analyses. Conclusions Overweight was negatively associated with mortality risk in older men with metabolic abnormalities but not in those without metabolic abnormalities. Obesity did not increase death risk regardless of metabolic abnormalities. These findings suggest that the recommendation of pursuing a normal weight may be wrong in overweight/obese older men, especially for those with metabolic abnormalities.展开更多

文摘Polyploid plants grow well,are stress tolerant,and are rich in nutrients and bioactive compounds.Thus,they are useful for improving crop quality and yield.In this study,we compared the seed characteristics and metabolite profiles of diploid and tetraploid tartary buckwheat,which was developed via an artificially induced chromosome doubling event.The length,width,area,and thousand-grain weight were greater for the tetraploid seeds than for the diploid seeds.However,the germination rate decreased for the tetraploid seeds.Additionally,there was a gap between the shell and kernel of the tetraploid seeds.Moreover,the water absorption rate was higher for the tetraploid than for the diploid seeds.Chromosome doubling increased the seed total flavonoid content and deepened the seed color.A principal component analysis of the ultrahigh-pressure liquid chromatography-high resolution mass spectrometry data revealed the clear separation between the diploid and tetraploid samples.An orthogonal partial least squares-discriminant analysis and other multivariate statistical analyses identified 83 differentially abundant compounds,with most of the flavonoid metabolites more abundant in the tetraploid than in the diploid seeds.Research on tartary buckwheat polyploidy may result in enhanced germplasm resources and may clarify the mechanism underlying the biosynthesis of bioactive compounds.

文摘Stress is an inevitable interference factor that seriously affects health.Listening to music is an economical,noninvasive,and highly accepted tool for easing stress.However,physiological studies investigating the ability of music to reduce stress in daily life are limited.We established rat models of chronic immobilization stress(CIS)to observe changes in the hypothalamic arcuate nucleus(ARC)neurons involved in the regulation of food intake and the effect of comfortable classical music exposure.Twenty-one days of stress resulted in decreased food intake and delayed body weight gain,up-regulation of leptin receptor(Ob-R),cocaine-and amphetamine-regulated transcript(CART),proopiomelanocortin(POMC),and alpha-melanocyte-stimulating hormone(α-MSH)expression,and downregulation of neuropeptide Y(NPY)and agouti-related protein(AgRP)expression in the ARC.Thus,peripheral leptin entered the ARC under chronic stress conditions,bound to Ob-R,and affected downstream nerve pathways related to appetite,such as the NPY/AgRP and CART/POMC pathways.Gentle classical music played at 65 dB reversed the abnormal expression of Ob-R and NPY induced by chronic stress.Thus,listening to comfortable music improves changes in ARC neurons related to the regulation of food intake in CIS rats,and these results provide a reference for basic research regarding how music therapy alleviates stress and stress-related health issues.
文摘Pdx-1, an important transcription factor highlighting in the early pancreatic development, islet functions and pancreatic disorders, needs to be more investigated in zebrafish, and siRNA is still seldom applied in zebrafish embryo-related research.Our aim was to explore the role of pdx-l in pancreatic development of zebrafish embryos by using siRNA approach. Microinjection, reverse transcriptase-PCR （RT-PCR）, in situ hybridization and immunofluorescent staining were used in this research, and the morphology of the islet in normal zebrafish embryos, and in those treated with the siRNA specific to pdx-1 （siPDX-l） or siGFP was observed and compared. The expression of pdx-1 was detected in the stages of 1-cell, 2-cell, 4-cell, 8-cell, 16-cell, 16-hour by RT-PCT. The in situ hybridization and immunofluorescent staining results showed that siPDX-1 disturbed the formation of the islet in zebrafish embryos. Pdx-1 played multiple roles in maintaining the phenotype of the islet during embryogenesis in zebrafish.
文摘Acrosin binding protein(ACRBP)is restrictedly expressed in sperm acrosomes and involved in many important reproductive processes.Here we investigated the immunocontraceptive effects of ACR BP peptide-based vaccines.B-cell epitope vaccines of mouse ACRBP were predicted by bioinformatics and prepared by vector coupling and adjuvant combination.Subsequently,female mice were actively immunized with the epitope vaccines subcutaneously,and the titers and specificity of anti-ACRBP antibodies were detected.Then the efficancy,safety and reversibility of epitope vaccines for contraception were evaluated in vivo and in vitro.

文摘BACKGROUND Post-traumatic stress disorder(PTSD)is a serious stress-related disorder.AIM To identify the key genes and pathways to uncover the potential mechanisms of PTSD using bioinformatics methods.METHODS Gene expression profiles were obtained from the Gene Expression Omnibus database.The differentially expressed genes(DEGs)were identified by using GEO2R.Gene functional annotation and pathway enrichment were then conducted.The gene-pathway network was constructed with Cytoscape software.Quantitative real-time polymerase chain reaction(qRT-PCR)analysis was applied for validation,and text mining by Coremine Medical was used to confirm the connections among genes and pathways.RESULTS We identified 973 DEGs including 358 upregulated genes and 615 downregulated genes in PTSD.A group of centrality hub genes and significantly enriched pathways(MAPK,Ras,and ErbB signaling pathways)were identified by using gene functional assignment and enrichment analyses.Six genes(KRAS,EGFR,NFKB1,FGF12,PRKCA,and RAF1)were selected to validate using qRT-PCR.The results of text mining further confirmed the correlation among hub genes and the enriched pathways.It indicated that these altered genes displayed functional roles in PTSD via these pathways,which might serve as key signatures in the pathogenesis of PTSD.CONCLUSION The current study identified a panel of candidate genes and important pathways,which might help us deepen our understanding of the underlying mechanism of PTSD at the molecular level.However,further studies are warranted to discover the critical regulatory mechanism of these genes via relevant pathways in PTSD.
文摘The color of plants is mainly due to the rich content of chlorophylls,carotenoids,betalains,flavonoids,and other substances.Anthocyanins as an important group of flavonoids,have an important effect on the color of plant tissues,especially fruit color[1,2].In the early 1900s,a summary of Mendelian studies on pea coloration was given by Weldon[3].Since then,the anthocyanin biosynthetic pathway has been continuously refined,until it was first summarized in plants in detail[4].Anthocyanins are important secondary metabolites in plants.

文摘Tartary buckwheat(Fagopyrum tataricum)is an important pseudocereal feed crop with medicinal and nutritional value.Drought is one of the main causes of reduced growth and yield in these plants.We investigated the growth,physiological,and metabolic responses of the widely promoted Tartary buckwheat variety Chuan Qiao No.1 to polyethylene glycol(PEG)-mediated drought stress.Drought significantly decreased shoot length,shoot biomass and relative water content.Root length,malondialdehyde content,electrolyte leakage,activities of superoxide dismutase,peroxidase,catalase and amylase,and contents of soluble sugar,soluble protein and proline were increased by PEG-mediated drought.Untargeted metabolomics analysis identified 32 core metabolites in seedlings subjected to PEG-mediated drought,16 of which increased—including quercetin,isovitexin,cyanidin 3-O-beta-D-glucoside,L-arginine,and glycerophosphocholine,while the other 16 decreased—including 3-methoxytyramine,2,6-diaminopimelic acid,citric acid,UDP-alpha-D-glucose,adenosine,keto-D-fructose.The 32 core metabolites were enriched in 29 metabolic pathways,including lysine biosynthesis,citrate(TCA)cycle,anthocyanin biosynthesis,and aminoacyl-tRNA biosynthesis.Among them,taurine and hypotaurine metabolism,flavor and flavor biosynthesis,indole alkaline biosynthesis,and alanine,aspartate and glutamate metabolism were the four main metabolic pathways affected by drought.Our findings provide new insights into the physiological and metabolic response mechanisms of Tartary buckwheat to drought stress.

文摘The ancient books on traditional Chinese medicine(TCM) are the source of knowledge for TCM physicians. Therapeutic principles and therapeutic methods for healing many diseases are recorded in these ancient TCM books, providing a huge number of references for modern TCM physicians on conducting diagnosis and administering treatment for different diseases. The ancient TCM books can be dated back thousands of years, and this vast knowledge is recorded in different medical books in the form of text. However, it is difficult to systematically assimilate much information in ancient TCM books. At present, many researchers are applying advanced analytical techniques to analyze the text data in the ancient TCM books. Advanced techniques that have been applied include database construction, cognitive linguistic analysis, fuzzy logic, data mining, and artificial intelligence(AI) technology. There are different characteristics in these advanced analytical techniques. In this study, we comprehensively review recent advances in these techniques applied to the study of ancient TCM books. Furthermore, as AI technology is increasingly utilized in the medical field as well as in the study of ancient TCM books, we also review the application of AI technology to the study of ancient TCM books.

文摘Objective:The objective of this study was to systematically evaluate the clinical efficacy of the integration method of heat-clearing, dampness-excreting,spleen-strengthening, and stasis-removing from traditional Chinese medicine (TCM) combined with Western medicine for the treatment of ulcerative colitis(UC).Materials and Methods:The databases China National Knowledge Infrastructure,China Biology Medicinedisc(CBMdisc),WANFANG, VIP, and PubMed were searched for randomized controlled trials investigating the integration of the TCM methods of clearing heat,draining dampness, invigorating the spleen, and removing stasis, combined with Western medicine to treat UC from January 2009 to March 2019. Two reviewers independently conducted literature searches, screenings, data extractions, and literature bias evaluations. A meta-analysis was conducted using RevMan 5.3 and Stata 13.0 software. Results:In total, 15 studies involving 1289 patients were included. The results of the meta-analysis showed that the total effective rate of treatment in the experimental groups was higher than that of the control groups (relative risk [RR]=1.27, 95%confidence interval [CI]:1.21, 1.35, Z=8.74, P <0.00001). In the subgroup analysis, the total effective rate of oral TCM combined with Western medicine was higher than that of the control groups (RR=1.24, 95%CI:1.15, 1.33, Z=5.88, P <0.00001). The total effective rate of oral TCM with enemas combined with Western medicine was higher than that of the control group (RR=1.30, 95%CI:1.12, 1.50, Z=3.52, P=0.0004).The comparison between Western medicine alone and oral TCM combined with enteroscopy and Western medicine showed that the effective rate of enteroscopy (RR=1.18, 95%CI:1.05, 1.33, Z=2.86, P=0.004) and the symptom scores before and after treatment all improved more in the combined treatment groups than in those of the Western medicine group alone, with statistically significant differences (RR=-4.23, 95%CI:-4.93,-3.53, Z=11.84, P <0.00001). Conclusion:The integration of the TCM methods of heat clearing, dampness excreting, spleen strengthening, and stasis removing combined with Western medicine can significantly improve the cure rate of UC, and is an effective method to treat UC.
文摘Background Older adults are prone to obesity and metabolic abnormalities and recommended to pursue a normal weight especially when obesity and metabolic abnormalities are co-existed. However, few studies have reported the possible differences in the effect of obesity on outcomes between older adults with metabolic abnormalities and those without metabolic abnormalities. Methods A total of 3485 older men were included from 2000 to 2014. All-cause mortality and cardiovascular mortality were obtained during a mean follow-up of five years Metabolic abnormalities were defined as having established hypertension, diabetes, or dyslipidemia and taking the disease-related medications. All participants were stratified by the presence or absence of metabolic abnormalities. Results In the non-metabolic abnormalities group, all-cause and cardiovascular deaths were lowest in overweight participants and highest in obese participants. In the metabolic abnormalities group, mortality was also lowest in overweight participants but highest in participants with normal weight. After adjustment for covariates, hazard ratios （95% CI） for all-cause death and cardiovascular death were 0.68 （0.51, 0.92） and 0.59 （0.37, 0.93）, respectively, in overweight participants with metabolic abnormalities. Furthermore, obesity was not associated with mortality risk in both groups. These findings were unchanged in stratified analyses. Conclusions Overweight was negatively associated with mortality risk in older men with metabolic abnormalities but not in those without metabolic abnormalities. Obesity did not increase death risk regardless of metabolic abnormalities. These findings suggest that the recommendation of pursuing a normal weight may be wrong in overweight/obese older men, especially for those with metabolic abnormalities.
