SNHG14 Elevates NFAT5 Expression Through Sequestering miR-375-3p to Promote MPP + -Induced Neuronal Apoptosis, Inflammation, and Oxidative Stress in Parkinson's Disease.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by the loss of dopaminergic neurons. LncRNA small nucleolar RNA host gene 14 (SNHG14) was found to promote neuron injury in PD. Here, we investigated the mechanisms of SNHG14 in PD process. In vivo or in vitro PD model was established by using 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mice or 1-methyl-4-phenylpyridinium (MPP +)-stimulated SK-N-SH cells. The expression of genes and proteins was measured by qRT-PCR and Western blot. In vitro assays were conducted using ELISA, CCK-8, colony formation, EdU, flow cytometry, and Western blot assays, respectively. The oxidative stress was evaluated by determining the production of superoxide dismutase (SOD) and malondialdehyde (MDA). The direct interactions between miR-375-3p and NFAT5 (Nuclear factor of activated T-cells 5) or SNHG14 was verified using dual-luciferase reporter and RNA immunoprecipitation (RIP) assays. SNHG14 and NFAT5 were elevated, while miR-375-3p was decreased in MPTP-mediated PD mouse model and MPP + -induced SK-N-SH cells. Knockdown of SNHG14 or NFAT5, or overexpression of miR-375-3p reversed MPP + -induced neuronal apoptosis, inflammation, and oxidative stress. Mechanistically, SNHG14 directly bound to miR-375, which targeted NFAT5. Inhibition of miR-375-3p abolished the inhibitory activity of SNHG14 knockdown on MPP + -evoked neuronal damage. Besides that, NFAT5 up-regulation counteracted the effects of miR-375-3p on MPP + -mediated neuronal damage. SNHG14 contributed to MPP + -induced neuronal injury by miR-375/NFAT5 axis, suggesting a new insight into the pathogenesis of PD.

A cross-sectional study of the relationship between physical activity, diet quality, and high-sensitivity C-reactive protein in US adults.

BACKGROUND AND AIMS: High-sensitivity C-reactive protein (hs-CRP) is associated with many diseases, especially cardiovascular disease (CVD). Research into the independent and integrated relationships of physical activity and diet quality with hs-CRP across sex-specific cohorts is lacking. METHODS AND RESULTS: National Health and Nutrition Examination Survey data (2015-2018) was used to examine the relationship between physical activity and diet quality with hs-CRP and hs-CRP classified CVD risk using multiple multinormal logistic regression adjusted for covariates including demographics. Physical activity was measured using a self-reported survey and further categorized to those who met (MPAR) or did not meet (NPAR) national recommendations. Diet quality was measured using the Healthy Eating Index-2015, and further categorized to higher (HDQ) and lower (LDQ) diet quality. hs-CRP was also categorized as low, average, and high CVD risk using established cut-points. Physical activity was inversely related to hs-CRP in males (p < 0.001) whereas diet quality was inversely related to hs-CRP in females (p = 0.031). Compared to those with NPAR and LDQ, the hs-CRP for males with NPAR and HDQ and females with MPAR and HDQ was 1.18 mg/L and 0.75 mg/L lower respectively. Although, diet quality was inversely associated with high CVD risk in both sexes (p < 0.05), the lowest proportion of high and average CVD risk was observed in males and females with MPAR and HDQ. CONCLUSION: Physical activity and diet-quality lowered CVD risk regardless of sex. However, the independent effects of physical activity and diet quality on hs-CPR differs between sexes.

Investigation of the Inhibitory Effects of Illicium verum Essential Oil Nanoemulsion on Fusarium proliferatum via Combined Transcriptomics and Metabolomics Analysis.

Fusarium proliferatum is the main pathogen that causes Panax notoginseng root rot. The shortcomings of strong volatility and poor water solubility of Illicium verum essential oil (EO) limit its utilization. In this study, we prepared traditional emulsion (BDT) and nanoemulsion (Bneo) of I. verum EO by ultrasonic method with Tween-80 and absolute ethanol as solvents. The chemical components of EO, BDT, and Bneo were identified by gas chromatography-mass spectrometry (GC-MS) and the antifungal activity and mechanism were compared. The results show that Bneo has good stability and its particle size is 34.86 nm. The contents of (-) -anethole and estragole in Bneo were significantly higher than those in BDT. The antifungal activity against F. proliferatum was 5.8-fold higher than BDT. In the presence of I. verum EO, the occurrence of P. notoginseng root rot was significantly reduced. By combining transcriptome and metabolomics analysis, I. verum EO was found to be involved in the mutual transformation of pentose and glucuronic acid, galactose metabolism, streptomycin biosynthesis, carbon metabolism, and other metabolic pathways of F. proliferatum, and it interfered with the normal growth of F. proliferatum to exert antifungal effects. This study provide a theoretical basis for expanding the practical application of Bneo.

Multiomics strategies for decoding seed dormancy breakdown in Paris polyphylla.

BACKGROUND: The disruption of seed dormancy is a complicated process and is controlled by various factors. Among these factors, membrane lipids and plant hormones are two of the most important ones. Paris polyphylla is an important Chinese herbaceous species, and the dormancy trait of its seed limits the cultivation of this herb. RESULTS: In this study, we investigate the global metabolic and transcriptomic profiles of Paris polyphylla during seed dormancy breaking. Widely targeted metabolomics revealed that lysophospholipids (lysoPLs) increased during P. polyphylla seed dormancy breaking. The expression of phospholipase A2 (PLA2), genes correlated to the production of lysoPLs, up-regulated significantly during this process. Abscisic acid (ABA) decreased dramatically during seed dormancy breaking of P. polyphylla. Changes of different GAs varied during P. polyphylla seeds dormancy breaking, 13-OH GAs, such as GA53 were not detected, and GA3 decreased significantly, whereas 13-H GAs, such as GA15, GA24 and GA4 increased. The expression of CYP707As was not synchronous with the change of ABA content, and the expression of most UGTs, GA20ox and GA3ox up-regulated during seed dormancy breaking. CONCLUSIONS: These results suggest that PLA2 mediated production of lysoPLs may correlate to the seed dormancy breaking of P. polyphylla. The conversion of ABA to ABA-GE catalysed by UGTs may be the main cause of ABA degradation. Through inhibition the expression of genes related to the synthesis of 13-OH GAs and up-regulation genes related to the synthesis of 13-H GAs, P. polyphylla synthesized more bioactive 13-H GA (GA4) to break its seed dormancy.

The hypothalamic steroidogenic pathway mediates susceptibility to inflammation-evoked depression in female mice.

BACKGROUND: Depression is two-to-three times more frequent among women. The hypothalamus, a sexually dimorphic area, has been implicated in the pathophysiology of depression. Neuroinflammation-induced hypothalamic dysfunction underlies behaviors associated with depression. The lipopolysaccharide (LPS)-induced mouse model of depression has been well-validated in numerous laboratories, including our own, and is widely used to investigate the relationship between neuroinflammation and depression. However, the sex-specific differences in metabolic alterations underlying depression-associated hypothalamic neuroinflammation remain unknown. METHODS: Here, we employed the LPS-induced mouse model of depression to investigate hypothalamic metabolic changes in both male and female mice using a metabolomics approach. Through bioinformatics analysis, we confirmed the molecular pathways and biological processes associated with the identified metabolites. Furthermore, we employed quantitative real-time PCR, enzyme-linked immunosorbent assay, western blotting, and pharmacological interventions to further elucidate the underlying mechanisms. RESULTS: A total of 124 and 61 differential metabolites (DMs) were detected in male and female mice with depressive-like behavior, respectively, compared to their respective sex-matched control groups. Moreover, a comparison between female and male model mice identified 37 DMs. We capitalized on biochemical clustering and functional enrichment analyses to define the major metabolic changes in these DMs. More than 55% of the DMs clustered into lipids and lipid-like molecules, and an imbalance in lipids metabolism was presented in the hypothalamus. Furthermore, steroidogenic pathway was confirmed as a potential sex-specific pathway in the hypothalamus of female mice with depression. Pregnenolone, an upstream component of the steroid hormone biosynthesis pathway, was downregulated in female mice with depressive-like phenotypes but not in males and had considerable relevance to depressive-like behaviors in females. Moreover, exogenous pregnenolone infusion reversed depressive-like behaviors in female mice with depression. The 5α-reductase type I (SRD5A1), a steroidogenic hub enzyme involved in pregnenolone metabolism, was increased in the hypothalamus of female mice with depression. Its inhibition increased hypothalamic pregnenolone levels and ameliorated depressive-like behaviors in female mice with depression. CONCLUSIONS: Our study findings demonstrate a marked sexual dimorphism at the metabolic level in depression, particularly in hypothalamic steroidogenic metabolism, identifying a potential sex-specific pathway in female mice with depressive-like behaviors.

Sex and race/ethnicity specific reference predictive equations for abdominal adiposity indices using anthropometry in US adults.

BACKGROUND AND AIMS: Abdominal adiposity indices have stronger associations with cardiometabolic risk factors compared to anthropometric measures but are rarely used in large scale studies due to the cost and efficiency. The aim of this study is to establish sex and race/ethnicity specific reference equations using anthropometric measures. METHODS AND RESULTS: A secondary data analysis (n = 6589) of healthy adults was conducted using data from National Health and Nutrition Examination Survey 2011-2018. Variables included in the analyses were anthropometric measures (height; weight; waist circumference, WC) and abdominal adiposity indices (android percent fat; android to gynoid ratio, A/G ratio; visceral adipose tissue area, VATA; visceral to subcutaneous adipose area ratio, VSR). Multivariable prediction models were developed using quantile regression. Bland-Altman was used for external validation of prediction models. Reference equations to estimate android percent fat, A/G ratio, VATA and VSR from anthropometric measurements were developed using a randomly selected subsample of 4613. These reference equations for four abdominal adiposity indices were then cross-validated in the remaining subsample of 1976. The measured and predicted android percent fat, A/G ratio, VATA and VSR were not statistically different (p > 0.05) except for the A/G ratio in Asian males and VSR in White females. The results of Bland-Altman further revealed that ≥93% of predicted abdominal adiposity indices fell within the limits of agreement (±1.96 standard deviation). CONCLUSION: The sex and race/ethnicity specific reference equations for abdominal adiposity indices established using anthropometrics in the present study have strong predictive ability in US healthy adults.

Molecular Cloning and Functional Characterization of Oxidosqualene Cyclases from Panax vietnamensis.

Panax vietnamensis is a valuable medicinal resource with promising preclinical applications. Ginsenosides, which are triterpenoids, are the primary active components in P. vietnamensis. Oxidosqualene cyclases (OSCs) catalyze the formation of the basic skeleton of triterpenes from 2,3-oxidosqualene, which is a crucial step in the biosynthesis of triterpenoids. The OSCs involved in triterpenoid biosynthesis in P. vietnamensis have not yet been characterized. Four OSC genes (PvOSC1-4) were cloned from P. vietnamensis and functionally characterized via heterologous expression in yeast. Transgenic yeast expressing PvOSC1, PvOSC3, and PvOSC4 produced the corresponding products ß-amyrin, cycloartenol, and dammarenediol-II, respectively. PvOSC1, PvOSC3, and PvOSC4 are monofunctional OSCs. In this study, we characterized three PvOSC genes, providing a better understanding of the biosynthesis of triterpenoids in P. vietnamensis and the multiple choices of plant OSCs for metabolic engineering in yeast and other hosts.

Network pharmacology and fingerprint for the integrated analysis of mechanism, identification and prediction in Panax notoginseng.

INTRODUCTION: Panax notoginseng (Burkill) F. H. Chen ex C. H. Chow, is a well-known herb with multitudinous efficacy. In this study, a series of overall analyses on the action mechanism, component content, origin identification, and content prediction of P. notoginseng are conducted. OBJECTIVES: The purpose was to analyse the mechanism of pharmacological efficacy, differences between contents and groups of P. notoginseng from different origins, and to identify the origin and predict the content. MATERIALS AND METHODS: The P. notoginseng samples from four different origins were used for analysis by the database, network pharmacology (Q-marker) and fingerprint analysis [high-performance liquid chromatography (HPLC), attenuated total reflectance Fourier-transform infrared (ATR-FTIR) and near-infrared (NIR)] combined with data fusion strategy (low- and feature-level). RESULTS: Four saponins were identified as Q-markers, and exerted pharmacological effects on signalling pathways through 24 core targets. The qualitative and quantitative analysis of HPLC showed that there were differences among groups and different origins. Therefore, considering the need to treat diseases, combined with network database and network pharmacology, the suitable producing areas were determined through the mechanism of action and the required saponin content. The low-level data fusion successfully identified the origin and predicted the content of P. notoginseng from different origins. The accuracy rate of each evaluation index of the partial least squares discriminant analysis (PLS-DA) model was 1, and the t-SNE (t-distributed stochastic neighbor embedding) visualisation results were good. The coefficient of determination (R2 ) of the partial least squares regression (PLSR) model ranged from 0.9235-0.9996, and the root mean square error of cross-validation (RMSECV) and root mean square error of prediction (RMSEP) range is 0.301-1.519. CONCLUSION: This study was designed to provide a sufficient theoretical basis for the quality control of P. notoginseng.

Cloning and Functional Characterization of NADPH-Cytochrome P450 Reductases in Aconitum vilmorinianum.

Diterpenoid alkaloids (DAs) are major pharmacologically active ingredients of Aconitum vilmorinianum, an important medicinal plant. Cytochrome P450 monooxygenases (P450s) are involved in the DA biosynthetic pathway, and the electron transfer reaction of NADPH-cytochrome P450 reductase (CPR) with P450 is the rate-limiting step of the P450 redox reaction. Here, we identified and characterized two homologs of CPR from Aconitum vilmorinianum. The open reading frames of AvCPR1 and AvCPR2 were found to be 2103 and 2100 bp, encoding 700 and 699 amino acid residues, respectively. Phylogenetic analysis characterized both AvCPR1 and AvCPR2 as class II CPRs. Cytochrome c and ferricyanide could be reduced with the recombinant proteins of AvCPR1 and AvCPR2. Both AvCPR1 and AvCPR2 were expressed in the roots, stems, leaves, and flowers of A. vilmorinianum. The expression levels of AvCPR1 and AvCPR2 were significantly increased in response to methyl jasmonate (MeJA) treatment. The yeasts co-expressing AvCPR1/AvCPR2/SmCPR1 and CYP76AH1 all produced ferruginol, indicating that AvCPR1 and AvCPR2 can transfer electrons to CYP76AH1 in the same manner as SmCPR1. Docking analysis confirmed the experimentally deduced functional activities of AvCPR1 and AvCPR2 for FMN, FAD, and NADPH. The functional characterization of AvCPRs will be helpful in disclosing molecular mechanisms relating to the biosynthesis of diterpene alkaloids in A. vilmorinianum.

[Prenatal diagnosis for a fetus with Walker-Warburg syndrome].

OBJECTIVE: To explore the genetic etiology for a fetus with Walker-Warburg syndrome(WWS). METHODS: A fetus with WWS diagnosed at Gansu Provincial Maternity and Child Health Care Hospital in June 9, 2021 was selected as the study subject. Genomic DNA was extracted from amniotic fluid sample of the fetus and peripheral blood samples from its parents. Trio-Whole exome sequencing (trio-WES) was carried out. Candidate variants were verified by Sanger sequencing. RESULTS: The fetus was found to harbor compound heterozygous variants of the POMT2 gene, namely c.471delC (p.F158Lfs*42) and c.1975C>T (p.R659W), which were respectively inherited from its father and mother. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), they were respectively rated as pathogenic (PVS1+PM2_Supporting+PP4) and likely pathogenic (PM2_Supporting+PM3+PP3_Moderate+PP4). CONCLUSION: Trio-WES may be used for the prenatal diagnosis of WWS. The compound heterozygous variants of the POMT2 gene probably underlay the disorder in this fetus. Above finding has expanded the mutational spectrum of the POMT2 gene and enabled definite diagnosis and genetic counseling for the family.

Control of pathogenic fungi on Panax notoginseng by volatile oils from the food ingredients Allium sativum and Foeniculum vulgare.

To screen natural drugs with strong inhibitory effects against pathogenic fungi related to P. notoginseng, the antifungal activities of garlic and fennel EOs were studied by targeting P. notoginseng disease-associated fungi, and the possible action mechanisms of garlic and fennel EOs as plant fungicides were preliminarily discussed. At present, the antifungal mechanism of EOs has not been fully established. Therefore, understanding the antifungal mechanism of plant EOs is helpful to address P. notoginseng diseases continuous cropping disease-related obstacles and other agricultural cultivation problems. First, the Oxford cup method and chessboard were used to confirm that the EOs and oxamyl had a significant inhibitory effect on the growth of Fusarium oxysporum. F. oxysporum is the main pathogen causing root rot of P. notoginseng and the preliminary study on the antifungal mechanisms of the EOs against F. oxysporum showed that the inhibition of EOs mainly affects cell membrane permeability and cell processes and affects the enzyme activities of micro-organism, to achieve antifungal effects. Finally, an in vivo model verified that both two EOs could significantly inhibit the occurrence of root rot caused by F. oxysporum.

Anticoagulant activity analysis and origin identification of Panax notoginseng using HPLC and ATR-FTIR spectroscopy.

INTRODUCTION: Panax notoginseng is one of the traditional precious and bulk-traded medicinal materials in China. Its anticoagulant activity is related to its saponin composition. However, the correlation between saponins and anticoagulant activities in P. notoginseng from different origins and identification of the origins have been rarely reported. OBJECTIVES: We aimed to analyze the correlation of components and activities of P. notoginseng from different origins and develop a rapid P. notoginseng origin identification method. MATERIALS AND METHODS: Pharmacological experiments, HPLC, and ATR-FTIR spectroscopy (variable selection) combined with chemometrics methods of P. notoginseng main roots from four different origins (359 individuals) in Yunnan Province were conducted. RESULTS: The pharmacological experiments and HPLC showed that the saponin content of P. notoginseng main roots was not significantly different. It was the highest in main roots from Wenshan Prefecture (9.86%). The coagulation time was prolonged to observe the strongest effect (4.99 s), and the anticoagulant activity was positively correlated with the contents of the three saponins. The content of ginsenoside Rg1 had the greatest influence on the anticoagulant effect. The results of spectroscopy combined with chemometrics show that the variable selection method could extract a small number of variables containing valid information and improve the performance of the model. The variable importance in projection has the best ability to identify the origins of P. notoginseng; the accuracy of the training set and the test set was 0.975 and 0.984, respectively. CONCLUSION: This method is a powerful analytical tool for the activity analysis and identification of Chinese medicinal materials from different origins.

Root-Associated Microbiomes of Panax notoginseng under the Combined Effect of Plant Development and Alpinia officinarum Hance Essential Oil.

Essential oils (EOs) have been proposed as an alternative to conventional pesticides to inhibit fungal pathogens. However, the application of EOs is considerably limited due to their highly volatile nature and unpredictable effects on other microbes. In our study, the composition of bacterial and fungal communities from the rhizosphere soil of P. notoginseng under four treatment levels of Alpinia officinarum Hance EO was characterized over several growth stages. Leaf weight varied dramatically among the four EO treatment levels after four months of growth, and the disease index at a low concentration (0.14 mg/g) of EO addition was the lowest among the P. notoginseng growth stages. The content of monomeric saponins was elevated when EO was added. Bacterial and fungal diversity in the absence of plants showed a decreasing trend with increasing levels of EO. Bacterial diversity recovery was more correlated with plant growth than was fungal diversity recovery. Compared with the control (no EO addition), a low concentration of EO significantly accumulated Actinomycota, including Acidothermus, Blastococcus, Catenulispora, Conexibacter, Rhodococcus, and Sinomonas, after one month of plant-microbial interaction. Overall, the results showed that both the plant growth stage and EOs drive changes in the microbial community composition in the rhizosphere of P. notoginseng. Plant development status had a stronger influence on bacterial diversity than on fungal diversity. EO had a more significant effect on fungal community composition, increasing the dominance of Ascomycota when EO concentration was increased. Under the interaction of P. notoginseng growth and EO, a large number of bacterial genera that have been described as plant growth-promoting rhizobacteria (PGPR) responded positively to low concentrations of EO application, suggesting that EO may recruit beneficial microbes in the root zone to cope with pathogens and reduce root rot disease. These results offer novel insights into the relationship between EO application, altered microbial communities in the plant roots, plant growth stage, and disease occurrence.

Down-Regulation of ID2-AS1 Alleviates the Neuronal Injury Induced by 1-Methy1-4-Phenylpyridinium in Human Neuroblastoma Cell Line SH-SY5Y Cells Through Regulating miR-199a-5p/IFNAR1/JAK2/STAT1 Axis.

We aimed to illustrate the roles and molecular mechanisms of ID2-AS1 in parkinson's disease (PD). Methods: qRT-PCR detected the expression of ID2-AS1. CCK-8, LDH release assays the effect of ID2-AS1 knockdown on PD cells. Flow cytometry and Western Blot were used to detect the effect of ID2-AS1 inhibition on PD cell apoptosis. ELISA analysis showed that ID2-AS1 inhibition can reduce the inflammation of PD cells. ROS activity assay showed that inhibiting ID2-AS1 attenuated the oxidative stress induced by 1-methy1-4-phenylpyridinium (MPP+). RNA binding protein immunoprecipitation assay showed that ID2-AS1 is mainly located in the cytoplasm. The luciferase reporter assay is used to verify the interaction. In our study, ID2-AS1 was concentration-dependently and time-dependently up-regulated in MPP+ -treated human neuroblastoma cell line SH-SY5Y. ID2-AS1 knockdown enhanced cell proliferation and decreased cell death in PD cells. Knockdown of ID2-AS1 attenuates MPP+ -induced cytotoxicity in SH-SY5Y cells. ID2-AS1 is a sponge of miR-199a-5p. IFNAR1 is a target of miR-199a-5p. Inhibition of miR-199a-5p and overexpression of IFNAR1 alleviate the inhibitory effect of ID2-AS1 knockdown on MPP+ triggered neuronal injury. Inhibition of miR-199a-5p and overexpression of IFNAR1 alleviate the inhibitory effect of ID2-AS1 knockdown on MPP+ -triggered JAK2/STAT1 activation. Overall, down-regulation of ID2-AS1 alleviated the neuronal injury in PD through regulating miR-199a-5p/IFNAR1/JAK2/STAT1 axis.

Chemical Constituents of the Essential oil from Cuminum cyminum L. and Its Antifungal Activity against Panax notoginseng Pathogens.

Cuminum cyminum L. (Cumin) is a flavoring agent that is commonly used worldwide, and is rich in essential oil. Essential oils (Eos) have been intensively investigated in regard to their potential for disease control in plants, which is provided a chance for the blossom of green pesticides. The chemical components of Cumin essential oil (CEO) were revealed by GC/MS, such as cuminaldehyde (44.53 %), p-cymene (12.14 %), (-)-ß-pinene (10.47 %) and γ-terpinene (8.40 %), and found they can inhibit the growth of P. notoginseng-associated pathogenic fungi in vitro and the inhibitory effect of cuminaldehyde was similar to that of hymexazol. SEM and TEM images demonstrated that cuminaldehyde and CEO increased cell permeability and disrupted membrane integrity. The expression of disease-related genes of Fusarium oxysporum showed that CEO induced the expression of most genes, which disrupted biosynthesis, metabolism and signaling pathways. These studies verified the potential of CEO as a plant fungicide that is environmentally friendly and provided ideas for developing new products for controlling root diseases that affect P. notoginseng.

Biological Activities of Two Essential Oils from Pogostemon cablin and Eupatorium fortunei and Their Major Components against Fungi Isolated from Panax notoginseng.

Panax notoginseng (Burkill) F.H.Chen (Araliaceae), of which the dry root and rhizome are precious traditional Chinese medicine, suffers severely from diseases during planting. Essential oils (EOs) with antimicrobial activity are a possibility for the development of green pesticides. We extracted EOs from Pogostemon cablin (Blanco) Benth. and Eupatorium fortunei Turcz., respectively and tested their inhibitory rates on fungi isolated from diseased P. notoginseng by the Oxford cup method. The compounds of the EO were identified by GC/MS and the minimum inhibitory concentrations (MICs) of the EOs and their main components were evaluated by the 96-well plate method. We also mixed P. cablin EO, E. fortunei EO and hymexazol in pairs to explore whether their combinations produce stronger antifungal effects than individual components. Finally, we evaluated the effects of the EOs against Fusarium oxysporum in vivo. P. cablin EO and E. fortunei EO exhibited different antifungal activities against fungi, with the inhibitory rates of 21.02 %-100 % and 54.84 %-100 % and MICs of 0.07-0.88 mg/mL and 0.20-1.17 mg/mL, respectively. Pogostone (24.96 %) and thymol (15.64 %) were the major compounds of P. cablin EO and E. fortunei EO, respectively, and they exhibited stronger antifungal activities than EOs, with MICs of 0.008-0.078 mg/mL and 0.12-0.31 mg/mL, respectively. Moreover, hymexazol was mixed with E. fortunei EO, and the inhibitory effect against Cylindrocarpon destructans was enhanced with a synergistic effect. The disease incidence and disease index of EO treatments decreased significantly in vivo. Based on our study, P. cablin EO and E. fortunei EO have great potential to be developed into green fungicides for use in agriculture to control diseases of P. notoginseng.

Age-specific trends in health-related quality of life among US adults: findings from National Health and Nutrition Examination Survey, 2001-2016.

PURPOSE: Health-related quality of life (HRQoL) is an important indicator of population health, yet no age-specific trend analyses in HRQoL have been conducted with a nationally representative sample since 2004. Therefore, to address this gap, an age-specific trend analysis of HRQoL was conducted using National Health and Nutrition Examination Surveys (NHANES) data. METHODS: NHANES 2001-2016 data (8 cycles) were examined to evaluate trends in HRQoL by age group (young adults: 21-39, middle-aged: 40-64, older adults: 65+). HRQoL was assessed by self-reported health (SRH) and number of physically unhealthy, mentally unhealthy, and inactive days to due to physical or mental health in the past 30 days. Multiple linear or logistic regression analyses explored trends in HRQoL by age group, adjusting for demographics over time. RESULTS: Analysis revealed increasing fair/poor SRH over time for the entire sample (ß = 0.34, 95% CI 0.08, 0.60, p = 0.011). However, age-specific analysis identified a bi-annual increase in fair/poor SRH only among young adults (ß = 0.49, 95% CI 0.22, 0.76, p < 0.001) and a decrease among older adults (ß = - 0.60, 95% CI - 1.14, - 0.06, p = 0.03). Closer inspection revealed increasing fair/poor SRH increased among young women (ß = 0.52, 95% CI 0.11, 0.93, p = 0.013) and young men (ß = 0.46, 95% CI 0.04, 0.88, p = 0.03) but decreased among older women (ß = - 0.81, 95% CI - 1.59, - 0.03, p = 0.042) over time. Analyses also determined that there was a trend for a decreasing number of physically unhealthy days among young adults (p < 0.001), although no trends were observed for the other HRQoL items. CONCLUSIONS: Although there was a significant trend over time for increasing fair/poor SRH when considering the entire sample, this trend was not consistent between age groups or sexes. Given increasing fair/poor SRH among young adults, there is a need to understand and address factors relating to HRQoL among this age group.

Antifungal Effect of Essential Oils from Five Kinds of Rutaceae Plants - Avoiding Pesticide Residue and Resistance.

Panax notoginseng root is a traditional Chinese herb, of which the yield and quality have been seriously affected by microorganisms, and is commonly used to treat various kinds of bleeding. In this experiment, the effects of the antifungal properties of essential oils (EOs) from five kinds of Rutaceae plants on the growth of three kinds of pathogens were studied to develop natural, environmentally friendly antifungal agents. Citrus medica EO was found to have stronger inhibitory effects on the growth of pathogenic fungi in vitro than other EOs with the Oxford cup method, of which the chemical composition was further investigated by GC/MS. The major components were d-limonene (22.79 %) and γ-terpinene (9.71 %). The antifungal activities were evaluated by MIC and FIC assays. In these assays, C. medica EO, d-limonene and γ-terpinene were effective against three pathogens of P. notoginseng with MIC values ranging from 0.12 to 12.05 mg/mL. The association between hymexazol and C. medica EO showed a high synergistic effect with lower FIC index values (FICi=0.31-2.00). Furthermore, C. medica EO was further assessed in P. notoginseng planted in a continuous cropping soil (CCS) and was found to reduce the disease incidence and disease severity compared with P. notoginseng planted in CCS only without EO addition. This finding suggested that C. medica EO has potential as a natural environmentally antifungal agent against pathogens of P. notoginseng, ensuring its safety.

Fungicidal Activity of Essential Oils from Cinnamomum cassia against the Pathogenic Fungi of Panax notoginseng Diseases.

The frequent disease of Panax notoginseng caused by the pathogenic fungi in field cultivation has become the major threaten to the sustainable development of it. The present study was conducted to find natural agent with potential inhibition against pathogen. Therefore, the inhibitory effects of Cinnamomum cassia (L.) J.Presl essential oils (EOs) against P. notoginseng associated pathogenic fungi were conducted both in vitro and in vivo experiments. The results of the Oxford cup test revealed that C. cassia dry bark EO (50 mg/mL) had significant inhibitory activity on the growth of all tested fungi, and the growth of various pathogens was completely inhibited, except for that of Fusarium solani. Therefore, the constituents of C. cassia EOs were analyzed by GC/MS, and the research demonstrated that the main constituents of C. cassia dry bark EO were trans-cinnamaldehyde (75.65 %), (E)-2-methoxycinnamaldehyde (6.08 %), cinnamaldehyde (3.47 %) and cinnamyl acetate (1.02 %). The MIC results showed that C. cassia dry bark EO and the main compounds had good antifungal effect on the tested strains, and the inhibitory effect was similar to that of hymexazol (chemical pesticide). By analyzing the value of the fraction inhibitory concentration index (FICI), additive effects, irrelevant effects and synergistic effects were observed after the mixture of hymexazol against various pathogens. Moreover, in vivo model showed that C. cassia dry bark EO could reduce the occurrence of anthrax in P. notoginseng. To widen the resources of C. cassia available, the compositions of both C. cassia fresh bark and leaf EOs were also tested and many common compositions existed among them. Taken together, it was concluded that C. cassia EO had the potential use in the field to reduce the pathogenic disease.

Monitoring Antifungal Agents of Artemisia annua against Fusarium oxysporum and Fusarium solani, Associated with Panax notoginseng Root-Rot Disease.

Root rot of Panax notoginseng has received great attention due to its threat on the plantation and sustainable utilization of P. notoginseng. To suppress the root-rot disease, natural ingredients are of great importance because of their environment friendly properties. In this study, we found that the methanol extract from Artemisia annua leaves has strong antifungal effects on the growth of Fusarium oxysporum and Fusarium solani resulting into root-rot disease. Essential oil (EO) thereof was found to be the most active. GC-MS analysis revealed 58 ingredients and camphor, camphene, ß-caryophyllene, and germacrene D were identified as the major ingredients. Further antifungal assays showed that the main compounds exhibit various degrees of inhibition against all the fungi tested. In addition, synergistic effects between A. annua EO and chemical fungicides were examined. Finally, in vivo experiments were conducted and disclosed that P. notoginseng root rot could be largely inhibited by the petroleum ether extract from A. annua, indicating that A. annua could be a good source for controlling P. notoginseng root-rot.
