Revealing Medicinal Constituents of Bistorta vivipara Based on Non-Targeted Metabolomics and 16S rDNA Gene Sequencing Technology.

Bistorta vivipara is a medicinal plant with a long history, but there are few studies on the effects of its medicinal components and endophytic bacteria on the accumulation of secondary metabolites. Therefore, in this study, non-targeted metabolomics techniques and 16s rDNA techniques were used to study B. vivipara from different regions. A total of 1290 metabolites and 437 differential metabolites were identified from all samples. Among them, flavonoids, isoflavonoids, and benzopyrans are the main medicinal components of B. vivipara; these have potential anticancer, antiviral, and antioxidant properties, as well as potential applications for the treatment of atrial fibrillation. In addition, irigenin, an important medicinal component, was identified for the first time. The endophytic bacterial communities in the root tissues of B. vivipara from different regions were also different in composition and richness. Hierarchical clustering heat map analysis showed that Proteobacteria and Actinobacteriota bacteria significantly affected the accumulation of many medicinal components in the roots of B. vivipara.

Phylogenetic relationship and characterization of the complete chloroplast genome of Rhododendron przewalskii subsp. przewalskii Maximowicz 1877, an ornamental and medicinal plant in China.

As one of the top 10 famous flowers in Chinese tradition, Rhododendron przewalskii subsp. przewalskii known as 'beauty in flowers,' which has high ornamental and medicinal value. The complete chloroplast (cp) genome of R. przewalskii subsp. przewalskii was determined in this study. The complete chloroplast genome of R. przewalskii subsp. przewalskii was 201,233 bp in length and contained a large single-copy region (LSC, 108,077 bp), and a small single-copy region (SSC, 2624 bp) and a pair of inverted repeat regions (IRa and IRb, 45,266 bp). A total of 142 functional genes were observed in this cp genome, including 91 protein-coding genes (PCGs), 43 transfer RNA genes (tRNAs), and eight ribosomal RNA genes (rRNAs). The R. przewalskii subsp. przewalskii cp genome has an A + T content of 64.06% and presents a positive AT-skew (0.53%) and a negative GC-skew (-1.56%). The maximum likelihood phylogenetic analysis based on the concatenated nucleotide sequences of 13 PCGs strongly supported the monophyletic relationship of R. przewalskii subsp. przewalskii the clade of R. henanense subsp. lingbaoense. This study provides genomic evidence for the vegetation classification of Rhododendron.

TRIM69: a marker of metastasis and potential sensitizer to 5-Fluorouracil and PD-1 blockers in colon adenocarcinoma.

BACKGROUND: Several proteins in the tripartite-motif (TRIM) family are associated with the development of colorectal cancer (CRC), but research on the role of TRIM69 was lacking. The present study examined the correlation between TRIM69 expression and colon adenocarcinoma (COAD). METHODS: mRNA sequencing data for COAD patients was extracted from The Cancer Genome Atlas to analyze correlations between TRIM69 expression and patients' clinical features as well as survival. Potential associations with immune cells and chemosensitivity also were predicted using various algorithms in the TIMER, Limma, clusterProfiler, GeneMANIA, and Gene Set Cancer Analysis platforms. Subsequently, polymerase chain reaction analysis and immunohistochemical staining were used to detect TRIM69 expression in COAD tissue samples from real-world patients. RESULTS: TRIM69 expression was lower in COAD tissues than in normal tissues and correlated with the pathologic stage and metastasis (M category). Additionally, TRIM69 was found to be involved in several immune-related pathways, notably the NOD-like signaling pathway. These results suggest that high TRIM69 expression has the potential to enhance tumor sensitivity to 5-fluorouracil and programmed cell death protein 1 (PD-1) blockers. CONCLUSIONS: From our findings that TRIM69 expression was significantly reduced in COAD compared with non-cancer tissues and associated with pathologic stage and metastasis, we conclude that increasing TRIM69 expression and/or activity may help to improve therapeutic outcomes. Accordingly, TRIM69 represents a potentially valuable marker of metastasis and target for adjuvant therapy in COAD.

Saikosaponin D reverses epinephrine- and norepinephrine-induced gemcitabine resistance in intrahepatic cholangiocarcinoma by downregulating ADRB2/glycolysis signaling.

Intrahepatic cholangiocarcinoma (iCCA) is a highly fatal malignancy with rapidly increasing incidence and mortality worldwide. Currently, gemcitabine-based systemic chemotherapy is the main clinical therapeutic regimen; however, its efficacy is poor, and its mechanism has not been elucidated. In this study, we use a Seahorse Extracellular Flux analyser to measure glycolysis capacity (extracellular acidification rate, ECAR) and oxygen consumption rate (OCR). The glucose uptake or lactic acid content is detected, and the effects of saikosaponin D, an active compound derived from Bupleuri Radix (a traditional Chinese medicine for soothing the liver and relieving depression), on gemcitabine cytotoxicity in norepinephrine-stimulated iCCA cells are analysed. We find that adrenergic signaling plays a fundamental role in chronic stress-induced therapeutic resistance in iCCA. Norepinephrine (NE) and epinephrine (E) enhance the proliferation of iCCA cells and interfere with the response to gemcitabine through activation of the ß2-adrenergic receptor (ADRB2). Furthermore, we find that NE upregulates the expressions of several drug efflux-related genes (such as ABCG2 and MDR1) and promotes glycolysis in iCCA cells. In addition, saikosaponin D reverses the poor response of iCCA cells to gemcitabine by downregulating ADRB2 level. Furthermore, saikosaponin D inhibits drug efflux and glycolysis in iCCA cells by regulating the expressions of MDR1, ABCG2, HK2, and GLUT1. Collectively, saikosaponin D enhances the antitumor effect of gemcitabine by controlling glucose metabolism and drug efflux by inhibiting the ADRB2 signaling. Therefore, the combination of saikosaponin D and gemcitabine may be a potential therapeutic strategy for the treatment of iCCA.

Selenium-containing soybean peptides ameliorate intestinal inflammation and modulate gut microbiota dysbacteriosis in DSS-induced ulcerative colitis mice.

The purpose of this study was to explore the protective effects of selenium containing soybean peptides (SePPs) on inflammatory bowel disease in colitis mice. During the experimental period, the mice were administered with SePPs for 14 days, and then treated with drinking water containing 2.5% dextran sodium sulfate (DSS) for 9 days, while the intervention of SePPs was continued. The results showed that low-dose SePPs (15 µg Se per kg per d bw) could effectively alleviate DSS-induced inflammatory bowel disease through the improvement of the antioxidant levels, reduction of inflammatory factor levels, and increase of tight junction protein expression of ZO-1 and occludin in the colon, thus improving the structure of the colon and strengthening the barrier function of the small intestine. Additionally, SePPs were found to significantly improve the production of short chain fatty acids (P < 0.05). Moreover, SePPs could improve intestinal microbiota diversity, significantly increasing the Firmicutes/Bacteroidetes ratio and the abundance of some beneficial genera, such as Lachnospiraceae_NK4A136_group and Lactobacillus (P < 0.05). Though high-dose SePPs (30 µg Se per kg per d bw) could improve DSS induced bowel disease, the effect was worse than that in the low-dose SePP group. These findings provide new insights into Se-containing peptides as a functional food against inflammatory bowel disease and dietary selenium supplementation.

Anti-depression-like effect of Mogroside V is related to the inhibition of inflammatory and oxidative stress pathways.

Siraitia grosvenorii (SG) is an edible medicinal plant found mainly in Guangxi, China, and Mogroside V (MGV) is the main component of SG extract. Previous research has shown that SG and MGV exert anti-inflammatory, antioxidative and neuroprotective effects. However, it is not clear whether MGV has anti-depression-like effect. In this study, we evaluated the neuroprotective effects and anti-depression-like effect of MGV both in vitro and in vivo. By performing in vitro tests, we evaluated the protective effects of MGV on PC12 cells with corticosterone-induced injury. In vivo tests, we used the chronic unpredictable mild stress (CUMS) depression model. Fluoxetine (10 mg/kg/day) and MGV (10 or 30 mg/kg/day) were administered by gavage for 21 days, and the open field test (OFT), novelty suppressed feeding test (NSFT), Tail suspension test (TST), and forced Swimming test (FST) were used to evaluate the depressive-like behaviors. In addition, we investigated the role of proinflammatory cytokines (IL-1ß, IL-6, and TNF-α) and anti-inflammatory cytokine (IL-4) in the hippocampal and cortex tissues. The levels of Superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione peroxidase (GSH-PX) in hippocampal and cortex tissues were also measured. Pathological changes in the hippocampal dentate gyrus and cortex regions were detected by immunofluorescence and Western blotting was used to measure the protein expression of BDNF, TrkB, TNF-α, and AKT. The results showed that MGV had a protective effect on PC12 cells with corticosterone-induced incurred injury. In addition, MGV treatment relieved the depressive symptoms and significantly reduced inflammatory levels (IL-1ß, IL-6, and TNF-α). MGV also significantly reduced oxidative stress damage and reduced the levels of apoptosis in hippocampal nerve cells. These results suggested that the anti-depressive effect of MGV may occur through the inhibition of inflammatory and oxidative stress pathways and the BDNF/TrkB/AKT pathway. These findings provide a new concept for the identification of new anti-depressive strategies.

Effects of carnitine on glucose and lipid metabolic profiles and fertility outcomes in women with polycystic ovary syndrome: A systematic review and meta-analysis.

OBJECTIVES: To quantify the effect of carnitine on glucose and lipid metabolic profiles and fertility outcomes in women with Polycystic ovary syndrome (PCOS). DESIGN: A systematic review and meta-analysis were conducted. PATIENTS: Women with PCOS diagnosed by Rotterdam or Androgen Excess Society (AES) criteria and taking carnitine supplement were assessment. MEASUREMENTS: Fertility outcomes (ovulation, clinical pregnancy, live birth, and miscarriage), lipid parameters (BMI, triglyceride, total cholesterol, high-density lipoprotein, low-density lipoprotein), fasting glucose and insulin, and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). RESULTS: In total, 839 participants were included in this analysis. The dosage of carnitine and treatment duration reported by studies varied from 250 mg to 3000 mg daily and 84 to 90 days, respectively. The publication bias was absent. Compared with placebo, carnitine significantly improved ovulation rates (RR 3.42, 95% CI 2.39 to 4.89, I2 = 0%) and pregnancy rates (RR 11.05, 95% CI 1.21 to 100.58, I2 = 79%). None of included studies reported live birth. After treatment, carnitine resulted in significant reductions relative to baseline in body mass index (BMI, MD -0.93 kg/m2, 95% CI -1.15 to -0.70, I2 = 55.0%), insulin levels (MD -2.47 mIU/L, 95% CI -4.49 to -0.45, I2 = 0%) and the Homeostasis Model Assessment index (MD -0.67, 95% CI -1.20 to -0.14, I2 = 0%) than placebo, but not for lipid profiles including triglyceride, total cholesterol, and low-density lipoprotein. CONCLUSION: With the available literature, carnitine seems to improve ovulation and clinical pregnancy and insulin resistance, BMI in women with PCOS. These effects are warranted to be further validated, due to insufficient statistical power.

Dietary interventions for better management of osteoporosis: An overview.

Osteoporosis is a public health concern and a cause of bone loss, increased risk of skeletal fracture, and a heavy economic burden. It is common in postmenopausal women and the elderly and is impacted by dietary factors, lifestyle and some secondary factors. Although many drugs are available for the treatment of osteoporosis, these therapies are accompanied by subsequent side effects. Hence, dietary interventions are highly important to prevent osteoporosis. This review was aimed to provide a comprehensive understanding of the roles of dietary nutrients derived from natural foods and of common dietary patterns in the regulation of osteoporosis. Nutrients from daily diets, such as unsaturated fatty acids, proteins, minerals, peptides, phytoestrogens, and prebiotics, can regulate bone metabolism and reverse bone loss. Meanwhile, these nutrients generally existed in food groups and certain dietary patterns also play critical roles in skeletal health. Appropriate dietary interventions (nutrients and dietary patterns) could be primary and effective strategies to prevent and treat osteoporosis across the lifespan for the consumers and food enterprises.

The effect of music therapy on anxiety and pain in patients undergoing prostate biopsy: A systematic review and meta-analysis.

OBJECTIVES: This study aims to explore the effect of music therapy on pain, anxiety and physiologic parameters in patients undergoing prostate biopsy. DESIGN AND SETTING: A systematic review and meta-analysis of randomized controlled trials. INTERVENTIONS: Five databases were systematically searched. The included studies reported randomized controlled trials comparing the effects of music therapy and non-music therapy on pain, anxiety, and physiologic parameters in patients undergoing prostate biopsy. The random-effects meta-analyses were performed for data synthesis. MAIN OUTCOME MEASURES: The primary outcome was pain; secondary outcomes included anxiety and physiologic parameters. RESULTS: We analyzed seven eligible studies involving 662 males undergoing prostate biopsy. We synthesized the mean difference between music and control groups in different outcomes. Compared with control groups, music therapy reduced pain (visual analog scale score, mean difference [95% CI]: -0.92 [-1.68 to -0.17], P = 0.017, low quality) and anxiety (State-Trait Anxiety Inventory equivalent scale score, mean difference [95% CI]: -4.37 [-7.72 to -1.03], P = 0.010, low quality) after the prostate biopsy. In terms of the physiological parameters, music therapy only slightly reduced heart rate, but not blood pressure and respiratory rate after the prostate biopsy. CONCLUSIONS: Low quality of evidence showed that music therapy during prostate biopsy might reduce pain and anxiety. However, a good standard of music intervention was lacking. Cost-effective analyses are warranted to better delineate the value of music therapies for prostate biopsy.

Berberine hydrochloride inhibits migration ability via increasing inducible NO synthase and peroxynitrite in HTR-8/SVneo cells.

ETHNOPHARMACOLOGICAL RELEVANCE: Inadequate trophoblasts migration and invasion is considered as an initial event resulting in preeclampsia, which is closely related to oxidative stress. Berberine hydrochloride (BBR), extracted from the traditional medicinal plant Coptis chinensis Franch., exerts a diversity of pharmacological effects, and the crude drug has been widely taken by most Chinese women to treat nausea and vomit during pregnancy. But there is no research regarding its effects on trophoblast cell function. AIM OF THE STUDY: This study aimed to investigate the effect of BBR on human-trophoblast-derived cell line (HTR-8/SVneo) migration ability and its mechanism. MATERIALS AND METHODS: Cell viability was detected by CCK-8 assay. The effect of BBR on cells migration function was examined by scratch wound healing assay and transwell migration assay. Intracellular nitric oxide (NO), superoxide (O2-) and peroxynitrite (ONOO-) levels were measured by flow cytometry. The expression levels of inducible NO synthase (iNOS), eNOS, p-eNOS, MnSOD, CuZnSOD, Rac1, NOX1, TLR4, nuclear factor-κB (NF-κB), p-NFκB, pro-inflammatory cytokines (TNF-α, IL-1ß and IL-6) in cells were analyzed by Western blotting. Uric acid sodium salt (UA), the scavenger of ONOO-, PEG-SOD (a specific superoxide scavenger), L-NAME (a NOS inhibitor) and antioxidants (Vit E and DFO) were further used to characterize the pathway of BBR action. RESULTS: 5 µM BBR decreased both the migration distance and the number of migrated cells without affecting cells viability in HTR-8/SVneo cells after 24 h treatment. BBR could increase the level of NO in HTR-8/SVneo cells, and the over-production of NO might be attributable to iNOS, but not eNOS. BBR could increase intracellular O2- levels, and the over-production of O2- is closely related with Rac1 in HTR-8/SVneo cells. The excessive production of NO and O2- further react to form ONOO-, and the increased ONOO- level induced by BBR was blunted by UA. Moreover, UA improved the impaired migration function caused by BBR in HTR-8/SVneo cells. The depressed migration function stimulated by BBR in HTR-8/SVneo cells was diminished by PEG-SOD and L-NAME. Furthermore, BBR increased the expression of IL-6 in HTR-8/SVneo cells, and antioxidants (Vit E and DFO) could decrease the expression of IL-6 and iNOS induced by BBR. CONCLUSIONS: BBR inhibits the cell migration ability through increasing inducible NO synthase and peroxynitrite in HTR-8/SVneo cells, indicating that BBR and traditional Chinese medicines containing a high proportion of BBR should be used with caution in pregnant women.

The efficacy and mechanism of acupuncture in the treatment of male infertility: A literature review.

Fertility, a social, cultural, and medical issue, has aroused public attention because of its potential to predict future health. In recent years, the incidence of male infertility has increased significantly, and various risk factors, such as congenital factors, acquired factors, and idiopathic factors, have led to this situation. Male infertility causes substantial psychological and social distress in patients. With the implementation of the two-child policy, male infertility has brought enormous psychological and social pressure and huge economic burden to patients and the healthcare system. This has attracted the attention of not only men of childbearing age but also many male experts. The conventional therapeutic approaches for treating male infertility, including drugs, varicocele surgery, intrauterine insemination, in vitro fertilization, and intracytoplasmic sperm injection, can restore fertility to a certain extent, but their efficacy is far from satisfactory, not to mention some adverse events. Therefore, acupuncture has been chosen by many men to treat their infertility and produced significant effects. In the present paper, the efficacy and mechanism of acupuncture in the treatment of male infertility were analyzed from different perspectives such as regulating hormone secretion, reducing inflammation, and improving semen parameters. The existing literature shows that acupuncture can effectively treat male infertility.

Anti-polycystic ovary syndrome effect of electroacupuncture: IMD inhibits ER stress-mediated apoptosis and autophagy in granulosa cells.

Polycystic ovary syndrome (PCOS) is a complicated endocrinopathy affecting women at reproductive age. Increasing evidence has shown the anti-PCOS effect of electroacupuncture (EA), a modified approach of traditional Chinese medical therapy "acupuncture". However, the underlying mechanism of EA-alleviated PCOS waits further explored. In this study, experimental PCOS were induced in rats by dehydroepiandrosterone (DHEA) injection. Testosterone (T)-induced human ovarian granulosa cell (GC) line KGN was used to mimic PCOS in vitro. EA significantly alleviated histological changes and hormone disruption in PCOS rats. Besides, EA inhibited cell apoptosis, autophagy and the activation of endoplasmic reticulum (ER) stress-related PERK/eIF2α/ATF4/CHOP signaling in ovaries of PCOS rats. More interestingly, intermedin (IMD), a member of calcitonin gene-related peptide (CGRP), was evidently up-regulated in ovarian GCs after EA treatment, and its main bioactive form IMD1-53 suppressed cell apoptosis, autophagy and PERK/eIF2α/ATF4/CHOP signaling in T-induced KGN cells. Consistent with IMD1-53, ER stress inhibitor 4-PBA exerted an inhibitory effect on T-induced cell apoptosis and autophagy in KGN cells. Collectively, this study validates the protective effect of EA on DHEA-induced PCOS, and proposes that IMD relieved apoptosis and autophagy in T-induced granulosa cells via inhibiting ER stress.

Modulation of oxidative stress and gut microbiota by selenium-containing peptides from Cardamine enshiensis and structural-based characterization.

The antioxidant properties of Se-containing peptides from Cardamine enshiensis (SeCPPs) and their impact on gut microbiota were studied in d-galactose (d-gal)- injected mice and antibiotic-treated mice. The structures of SeCPPs were identified by UPLC-Q-Extractive Orbitrap MS. In d-gal ageing mice, SeCPPs were associated with significantly decreased acetyl cholinesterase (AchE) activity, malondialdehyde (MDA) content, increased glutathione peroxidase (GSH-Px) activity, downregulated tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1ß (IL-1ß) levels (p < 0.05), and improved memory. In antibiotic-treated mice, SeCPPs were associated with reduced Proteobacteria and evaluated Akkermansia abundances (p < 0.01). Eighty-five Se-containing peptides were identified in SeCPPs. Peptides such as RV-SeM-I, RA-SeM-T and R-SeC-K showed low binding energy with 1,1-diphenyl-2-picrylhydrazyl (DPPH), and their binding affinities were confirmed by molecular docking. Overall, compared with Na2SeO3 and SeMet, SeCPPs showed superior antioxidant activity via their association with higher antioxidant enzyme activity, scavenging free radical properties and gut microbiome modulation.

Screening and bioavailability evaluation of anti-oxidative selenium-containing peptides from soybeans based on specific structures.

Our previous study has evaluated the antioxidant capacity and identified the sequences of soybean selenium-containing peptides. Herein, pharmacophore screening, gastrointestinal simulation and in vivo pharmacokinetics were performed to predict the potentials of selenium-containing peptides in terms of antioxidant activity, safety and bioavailability. A pharmacophore model with 6 structure features was constructed for virtual screening to determine the potential activities of 85 selenium sequences from soybean peptides. Strong reversing effects (p < 0.05) of the targeted sequences were observed in tumor necrosis factor-α (TNF-α)-induced inflammatory cytokines and adhesion factors burst in EA·hy926/Caco-2 co-culture cell models. Ser-Phe-Gln-SeMet (SFQSeM), a promising peptide selected from both virtual screening and cell models, was proved to be stable in the gastrointestinal tract and could be transported across the Caco-2 monolayer via the paracellular pathway. Additionally, SFQSeM showed a long residence time (89.42 ± 1.34 min) and half-life (81.60 ± 11.88 min) after consumption, and it induced lower liver alanine/aspartate transaminase (ALT/AST) and serum nitric oxide (NO) levels compared to Na2SeO3 and SeMet (p < 0.05). The potency of SFQSeM against oxidative stress as well as its oral bioavailability and low risk highlight its potential utility as an effective Se nutritional supplement.

An exploration of optimal time and safety of 595-nm pulsed dye laser for the treatment of early superficial infantile hemangioma.

Infantile hemangioma (IH) is the most common benign vascular tumor that occurs in infants and young children. Studies have shown laser therapy to reduce the proliferation of superficial IH and promote its regression, but the optimal timing for treatment has not been determined. Our study explores the timing and safety of 595-nm pulsed dye laser (PDL) treatment for early superficial IH. We retrospectively analyzed 180 cases of superficial IH treated with 595-nm PDL. Data was organized according to patient age at the first visit. Six months after the initial treatment, patients were evaluated using a grade IV classification method, and the clinical curative effect of each group was calculated. The number of laser treatments and the occurrence of adverse reactions were recorded simultaneously. The overall effective and cure rates were 98.3% and 84.4%, respectively, with no significant difference in rates between groups (p > 0.05). There was a statistically significant difference in the number of laser treatments among the age groups (p < 0.05). The average laser frequency: "0-2 months group" < "2-4 months group" < "4-6 months group." The overall incidence of adverse reactions was 11.1%, and 12 (6.7%) cases had short-term adverse reactions, with no statistically significant differences between groups (p > 0.05). Eight cases had long-term adverse reactions. This difference between groups was statistically significant (p < 0.05). Younger children (≤2 months of age) receiving 595-nm PDL treatment for IH require relatively fewer treatment times than other children (>2 months of age), have a shorter course of disease, experience better curative effect, and have fewer sequelae reactions.

Albumin/Globulin Ratio as Yin-Yang in Rheumatoid Arthritis and Its Correlation to Inflamm-Aging Cytokines.

PURPOSE: Inflamm-aging is a novel-concept in rheumatoid arthritis (RA) with accelerating aging process. We try to find a correlation between serum albumin/globulin (A/G) ratio and clinical biochemical parameters, incidence of aging-related diseases (ARDs) as well as inflammaging-related molecules. PATIENTS AND METHODS: Healthy controls (HC) and RA patients were compared with their clinical biochemical parameters including albumin and globulin levels, A/G ratio, and levels of serum lipids. Incidence of ARDs in RA was compared with A/G ratio, having a cut off value of 1.2. Expression levels of leptin and Trf2 genes in PBMCs, and inflammatory factors like IL-1ß, IL-6, IL-8 and TNF-ɑ between HC and RA patients were compared, and correlated with the A/G ratio. RESULTS: Compared to HC, RA patients had decreased levels of albumin, while globulin levels were found to be increased, which led to a significantly lower A/G ratio in RA patients. A/G ratio rather than ESR and CRP had significant correlation with dyslipidemia in RA patients. Patients with A/G <1.2 had a higher risk of ARDs than patients with A/G >1.2. The RR was 2.48 (95% CI: 1.79 to 3.64, p <0.0001). In addition, A/G ratio has positively correlated to leptin and Trf2 expression, while an inverse correlation was observed with the levels of inflamm-aging related cytokines like IL-6, IL-8 and TNF-ɑ. CONCLUSION: A decreased A/G ratio in RA patients has significantly correlated with dyslipidemia and ARDs, as well as inflammaging- related adipokine and pro-inflammatory cytokines. Thus, A/G ratio could be a reliable marker for evaluating the inflammaging process during clinical management in ARDs.

Greenway Cyclists' Visual Perception and Landscape Imagery Assessment.

Greenway is a kind of corridors in the city that takes natural elements as the main constituent foundation and connects open spaces with functions such as leisure and recreation. The assessment of the built greenway is a review of the past construction experiences, and it is also a supplement and improvement to the future greenway planning concept system, which has important academic and application value. This study will explore how greenway design factors influenced the local cyclists' perception of the landscape using on-site questionnaire and photo rating method. The results indicated that greenways with continuous cycling paths, high security awareness, open landscapes, and rich human activities evoke positive perceptions. Among the visual elements, natural elements such as plants and sky are more favorable than artificial elements. The research results show that the formation of greenway cyclists' landscape imagery is affected by visual perception elements, which suggests that special consideration should be given to the laws of cyclists' mental perception when designing greenways.

The effect of prenatal music therapy on fetal and neonatal status: A systematic review and meta-analysis.

OBJECTIVES: This study aims to investigate the effects of prenatal music therapy on fetal and neonatal status. DESIGN AND SETTING: A systematic review and meta-analysis of randomized controlled trials. INTERVENTIONS: Ovid MEDLINE, Embase, Web of Science, Cochrane Library, and Chinese Biomedical Literature Database were searched for studies investigating the effects of prenatal music therapy. Two independent investigators carried out the literature selection, data analysis, and evidence quality assessment. Eligible studies were qualitatively described and synthesized using meta-analyses. MAIN OUTCOME MEASURES: The outcomes included fetal or neonatal status. RESULTS: After screening the 821 records yielded by the systematic search, we identified nine eligible studies involving 1419 pregnant women. Eight studies were included in the meta-analysis, and three outcomes were synthesized. Compared with no music therapy, prenatal music therapy did not change fetal heart rate (mean difference [95 % CI]: -0.28 [-3.75-3.20] beat/min, P = 0.88, moderate quality), number of fetal movements (mean difference [95 % CI]: 0.50 [-0.79-1.78] time/min, P = 0.45, low quality), or number of accelerations (mean difference [95 % CI]: 0.16 [-0.87-1.19] time/min, P = 0.76, low quality). This result did not change when two studies with a high risk of bias were excluded. Subgroup analysis showed that prenatal music therapy did not change fetal heart rate, number of fetal movements, or number of accelerations in different intervention phases. CONCLUSIONS: Prenatal music therapy might not change fetal and neonatal status. However, more systematic strategies of prenatal music therapy deserve further exploration.

Selenium-containing soybean antioxidant peptides: Preparation and comprehensive comparison of different selenium supplements.

Present study aimed to prepare and identify antioxidative peptides from selenium-containing soybeans, and to investigate their bioavailability and protective effects against oxidative stress-related diseases. Selenium-containing soybean antioxidative peptides (Mw < 1 kDa, SePPs) hydrolyzed by Neutrase and Alcalase reached the highest cellular antioxidant activity (EC50 value 320.5 ± 39.71 µg/L). SePPs could be efficiently absorbed through Caco-2 monolayer, and then significantly reverse the tumor necrosis factor-α (TNF-α)-induced inflammatory cytokine, phosphorylated c-Jun N-terminal kinases (p-JNK) and nuclear factor-kappa B (NF-κB) levels in EA. hy926 cells (p < 0.05). d-galactose-induced aging mice model showed that liver superoxidase dismutase (SOD) and glutathione peroxidase-1 (GPx-1) were enhanced, while aspartate aminotransferase (AST), alanine aminotransferase (ALT) and NF-κB were decreased by SePPs significantly (p < 0.05). SePPs could inhibit brain oxidative stress via regulating MAPK/NF-κB pathway. Comparing with Na2SeO3, selenomethionine (SeMet) and selenium-free peptides, SePPs was found to present synergistic effects of selenium and peptides in antioxidant activity.

The complete chloroplast genome of Callicarpa bodinieri (Lamiales, Lamiaceae), an ornamental and medicinal plant from Chongqing, China.

Plants classified to the genus Callicarpa L. have important medicinal and ornamental value. Here, we report and characterize the complete chloroplast (cp) genome of C. bodinieri to provide molecular basis for the further studies on the phylogeny analysis of this genus. The cp genome is 154,183 bp in length and is organized with a typical quadripartite structure, containing two inverted repeats of 25,701 bp separated by a large single-copy region of 84,956 bp and a small single-copy region of 17,825 bp. The cp genome of C. bodinieri contains 112 distinct genes, including 78 protein-coding, 30 tRNAs and 4 rRNAs genes. The phylogenetic analysis showed that C. bodinieri is fully resolved in a clade with C. nudiflora, sister to the clade of C. formosana and C. longifolia var. floccosa.
