RESUMEN
Obesity, a multifactorial disease with many complications, has become a global epidemic. Weight management, including dietary supplementation, has been confirmed to provide relevant health benefits. However, experimental evidence and mechanistic elucidation of dietary supplements in this regard are limited. Here, the weight loss efficacy of MHP, a commercial solid beverage consisting of mulberry leaf aqueous extract and Hippophae protein peptides, was evaluated in a high-fat high-fructose (HFF) diet-induced rat model of obesity. Body component analysis and histopathologic examination confirmed that MHP was effective to facilitate weight loss and adiposity decrease. Pathway enrichment analysis with differential metabolites generated by serum metabolomic profiling suggests that PPAR signal pathway was significantly altered when the rats were challenged by HFF diet but it was rectified after MHP intervention. RNA-Seq based transcriptome data also indicates that MHP intervention rectified the alterations of white adipose tissue mRNA expressions in HFF-induced obese rats. Integrated omics reveals that the efficacy of MHP against obesogenic adipogenesis was potentially associated with its regulation of PPARγ and FGFR1 signaling pathway. Collectively, our findings suggest that MHP could improve obesity, providing an insight into the use of MHP in body weight management.

OBJECTIVE: The pathogenesis of diarrhea-predominant irritable bowel syndrome (IBS-D) is related to damage to the intestinal mucosal barrier function. Based on the Mast cell (MC)/Tryptase/Protease-activated receptor-2 (PAR-2)/Myosin light chain kinase (MLCK) pathway, this study explored the effect of electroacupuncture (EA) on IBS-D rats and its possible mechanism of protecting the intestinal mucosal barrier. METHODS: The IBS-D rat model was established by mother-offspring separation, acetic acid enema, and chronic restraint stress. The efficacy of EA on IBS-D rats was evaluated by observing the rate of loose stool (LSP) and the minimum volume threshold of abdominal withdrawal reflex (AWR) in rats. Mast cells and the ultrastructure of intestinal mucosa were observed by H&E staining, toluidine blue staining, and transmission electron microscopy. The expression levels of Tryptase, PAR-2, MLCK, zonula occludens-1 (ZO-1), and Occludin in rats were detected by ELISA, qRT-PCR, and western blot. RESULTS: After 7 days of intervention, compared to the IBS-D group, the loose stool rates of rats in IBS-D + EA group and IBS-D + ketotifen group were decreased (P < 0.01), the minimum volume thresholds of AWR were improved (P < 0.01), the inflammation of colon tissue decreased, the number of MCs were decreased (P < 0.01), the expression of Tryptase, PAR-2, and MLCK were lowered (P < 0.01, P < 0.05), and the expression of ZO-1 and Occludin were enhanced (P < 0.01, P < 0.05). Compared to the EA group, there was no significant difference in each index between the ketotifen groups (P > 0.05). CONCLUSION: EA has a good therapeutic effect on IBS-D rats. Regulating the MCs/Tryptase/PAR-2/MLCK pathway may be a mechanism to protect the intestinal mucosal barrier.
RESUMEN
BACKGROUND: There is a U-shaped relationship between dietary selenium (Se) ingestion and optimal sperm quality. OBJECTIVES: This study aimed to investigate the optimal dietary dose and forms of Se for sperm quality of breeder roosters and the relevant mechanisms. METHODS: In experiment 1, 18-wk-old Jingbai laying breeder roosters were fed a Se-deficient base diet (BD, 0.06 mg Se/kg), or the BD + 0.1, 0.2, 0.3, 0.4, 0.5, or 1.0 mg Se/kg for 9 wk. In experiment 2, the roosters were fed the BD or the BD + sodium selenite (SeNa), seleno-yeast (SeY), or Se-nanoparticles (SeNPs) at 0.2 mg Se/kg for 9 wk. RESULTS: In experiment 1, added dietary 0.2 and 0.3 mg Se/kg led to higher sperm motility and lower sperm mortality than the other groups at weeks 5, 7, and/or 9. Furthermore, added dietary 0.2-0.4 mg Se/kg produced better testicular histology and/or lower testicular 8-hydroxy-deoxyguanosine than the other groups. Moreover, integrated testicular transcriptomic and cecal microbiomic analysis revealed that inflammation, cell proliferation, and apoptosis-related genes and bacteria were dysregulated by Se deficiency or excess. In experiment 2, compared with SeNa, SeNPs slightly increased sperm motility throughout the experiment, whereas SeNPs slightly reduced sperm mortality compared with SeY at week 9. Both SeY and SeNPs decreased malondialdehyde in the serum than those of SeNa, and SeNPs led to higher glutathione peroxidase (GPX) and thioredoxin reductase activities and GPX1 and B-cell lymphoma 2 protein concentrations in the testis compared with SeY and SeNa. CONCLUSIONS: The optimal dietary Se dose for reproductive health of breeder roosters is 0.25-0.35 mg Se/kg, and SeNPs displayed better effects on reproductive health than SeNa and SeY in laying breeder roosters. The optimal doses and forms of Se maintain reproductive health of roosters associated with regulation intestinal microbiota homeostasis and/or testicular redox balance, inflammation, cell proliferation, and apoptosis.

PURPOSE: To evaluate the effectiveness of the constructed OOIDE intervention in patients with advanced cancer. METHOD: In this study, patients were invited to participate in a 4-week OOIDE intervention. The assessment of patients' ability to cope with death was conducted using a scale in conjunction with interviews. Additionally, patients' 'readiness to die' was assessed. RESULTS: Thirty-two patients with advanced cancer participated in this study. Our intervention significantly enhanced their perspective on life and spirituality, while also reducing their fear of death (P < 0.01). Furthermore, it facilitated their acceptance of death, encouraged a more rational approach to their illness, and fostered an understanding of hospice care, thereby reinforcing their sense of self-worth. Additionally, the intervention improved the relationship between the patient and their families, fostering greater mutual understanding and respect for the patient's perspectives. Comparing the results to the pre-intervention period, there was a significant increase in the number of patients who discussed death with their families and contemplated the place of their passing (P < 0.05). CONCLUSION: OOIDE improves participants' ability to confront death, while also assisting patients' families in the physical and psychological preparations for the loss of their relative.

Objective: To investigate the correlation of CT perfusion-related parameters with serum vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (BFGF) in patients with primary liver cancer. Methods: A total of 100 patients with primary liver cancer who were treated in our hospital from June 2019 to June 2021 were selected as the observation group, and 90 patients with benign liver lesions during the same period were selected as the control group. The CT perfusion-related parameters (perfusion volume and perfusion index) and serum VEGF and BFGF levels were compared between the two groups. Pearson correlation was used to analyze the correlation between CT perfusion-related parameters and serum VEGF and BFGF levels. Results: Compared to the control group, significantly higher HAP and lower HPP and TLP were observed in the observation group. The perfusion volume indexes of patients with different stages of liver cancer in the observation group were statistically different (P < 0.05). Compared to the control group, the observation group witnessed significantly higher HAPI and lower HPPI. There were statistically significant differences in the perfusion index of patients with different stages of primary liver cancer in the observation group (P < 0.05). The serum VEGF and BFGF levels in the observation group were significantly higher than those in the control group, and the serum VEGF and BFGF levels in patients with different stages of primary liver cancer in the observation group were statistically different (P < 0.05). Pearson correlation analysis showed that HAP and HAPI were positively correlated with VEGF and BFGF (r = 0.986, P ≤ 0.001; r = 0.983, P ≤ 0.001), and HPP, TLP, and HPPI were negatively correlated with VEGF and BFGF (r = -0.992, P ≤ 0.001; r = -0.993, P ≤ 0.001; r = -0.995, P ≤ 0.001). Conclusion: CT perfusion-related parameters and serum VEGF and BFGF levels in patients with primary liver cancer are abnormally expressed, and there is a strong correlation between the two, which might aid clinical diagnosis and treatment.
RESUMEN
In the present work, the biotransformation of ginsenosides in white ginseng roots was innovatively investigated using the aerobic fermentation by the co-cultivation of Bacillus subtilis and Trichoderma reesei. It is found that in the co-cultivation mode, the optimal nitrogen source was corn steep liquor, and the loading of ginseng powder and inoculation proportion of B. subtilis and T. reesei were 15 g/L and 1:4, respectively. The total ginsenoside yield and production of minor ginsenosides in the co-cultivation mode obviously enhanced in comparison to the monoculture mode. Meanwhile, the maximal total ginsenoside yield of 21.79% and high hydrolase activities were achieved using the staged inoculation at the inoculation proportion of 1:4 in the co-cultivation mode, the production of minor ginsenosides such as Rg3 and Rh1, Rh2 was significantly strengthened, and the pharmacological activities of the fermented solution obviously improved. The enhancement of ginsenoside transformation can be mainly attributed to hydrolysis of the produced hydrolases and metabolism of two probiotics. This result clearly reveals that using the staged inoculation in co-cultivation fermentation mode was favor of the ginsenoside biotransformation in ginseng due to non-synchronous cell growth and different metabolic pathways of both probiotics. This work can provide a novel method for enhancing ginsenoside transformation of ginseng.Key points⢠Co-cultivation fermentation significantly promoted ginsenoside biotransformation.⢠The staged inoculation in co-culture mode was an optimal operation method.⢠The pharmacological activity of the co-cultured solution was significantly enhanced.

In this study, modified whey protein hydrolysates (WPH) were obtained after succinic anhydride succinylation and linear dextrin glycation, and emulsion gels were prepared on the basis of unmodified/modified WPH stabilized emulsions with sugar beet pectin (SBP) addition and laccase-catalyzed cross-linking. The influences of emulsifier types and SBP contents on the texture of emulsion gels were estimated. The texture and rheological properties of emulsion gels were characterized. An ideal gel emulsion was formed when the SBP content was 3% (w/w). A uniform network was observed in emulsion gels stabilized by W-L, W-L-S, and W-S-L. In addition, the effect of the emulsifier type on the bioaccessibility of curcumin encapsulated in emulsion gels was investigated and the W-S-L stabilized emulsion gel exhibited the highest curcumin bioaccessibility (65.57%). This study provides a theoretical basis for the development of emulsion gels with different textures by SBP addition and laccase cross-linking as encapsulation delivery systems.

Phytochemical investigation of the ethyl acetate extract of Lycopodiastrum casuarinoides (Spring) Holub (Lycopodiaceae) led to the isolation of nine compounds, including two new serratene triterpenoids, serrat-14-en-3α,21α-diol (1), 26-nor-8-oxo-21-one-α-onocerin (6), one new abietane diterpenoid, lycocasuarinone A (7), one new sesquiterpene acid, 7, 9-diene-1,4-epoxy-2-hydroxy-10-carboxylic acid (8) and one new chromone derivative, 5,7-dihydroxy-2-methyl esterchromone (9), together with four known serratene triterpenoids (2-5). Abietane diterpenoid (7) and sesquiterpene acid (8) from Lycopodiastrum casuarinoides are reported for the first time. Their structures and stereochemistry were unambiguously elucidated by spectroscopic analysis and comparison with known ones. All the compounds were tested for acetylcholinesterase (AChE) and butyrocholinesterase (BuChE) inhibitory activities. Bioactivity assays revealed that compound 6 exhibited the most potent AChE inhibitory effect.

Six new neolignans, sinensiols B-G (1-6), together with three known analogues (7-9) were isolated from the whole plant of Selaginella sinensis. Their planar structures were established by comprehensive spectroscopic analyses including 1D, 2D NMR, IR and HRESIMS data. The absolute configurations of new compounds were elucidated by comparing their experimental CD spectra with known ones and using the reversed helicity rule for the 1Lb band ECD of dihydrobenzofuran neolignans. Sinensiols A-D (7, 1-3) belong to sesquilignan with a dimer of dihydrobenzo[b]furan moiety. The potential precursors of sinensiols A, B, D were also reported in this paper. In addition, all new compounds were screened for their cytotoxicity against A549 and HepG2 human cancer cell lines, and they didn't show inhibition on the growth of cancer cells.

In this paper, the effects of pectin (PE) with different concentrations on the pasting, rheological and digestibility properties of corn starch (CS) were evaluated. The Rapid Visco-Analyzer results showed that the peak viscosity was decreased with the concentrations of PE (0.5% and 1.0%) and then increased when the concentration of PE exceeded 2.0%. PE resulted in lower breakdown and setback values of CS. Rheological results revealed that the CS and CS-PE mixtures exhibited a pseudoplastic and shear-thinning behavior. The storage modulus (G') and loss modulus (Gâ³) of CS were increased with increasing PE concentrations from 2.0% to 10.0%. PE resulted in a decrease in the starch susceptibility to α-amylase and promoted a remarkable reduction (Pâ¯<â¯0.05) in the fraction of rapidly digested starch. The hydrolysis kinetic analysis suggested a decelerating effect of pectin on the hydrolysis rate of CS with lower values of equilibrium hydrolysis percentage (C∞) and kinetic constant (k).

Effects of pectin with different molecular weight (Mw) on gelatinization behavior, textural properties, retrogradation, and in vitro digestibility of corn starch (CS) were investigated. The pectin addition led to the decrease of peak, setback, and final viscosities of CS, and a further decrease was provided with the pectin of high Mw, whereas the pasting temperature was increased. The syneresis of starch gel during freeze-thaw process was reduced by the addition of pectin. High Mw pectin significantly lowered the hardness of the starch gel from 238.9 and 350.2â¯N to 222.7 and 318.5â¯N after 7 and 14â¯days storage (Pâ¯<â¯0.05), respectively. Compared with the retrograded CS alone, the relative crystallinity of starch-pectin mixtures significantly decreased (Pâ¯<â¯0.05), but the crystal type of starch remained unchanged. A significant increase was observed in both the proportion of slowly digestible starch and resistant starch for retrograded starch-pectin mixtures.

In order to increase the degree of substitution (DS), a combination of heat-moisture treatment (HMT) and octenyl succinylation (OSA) was used to modify sweet potato starch (SPS). The content of OSA had significant influence on the DS of starch, and DS of HMT OSA-modified SPS (HOSA-SPS) was higher than that of OSA-modified SPS (OSA-SPS), indicating that prior HMT could enhance the reaction. HOSA-SPS showed higher contents of SDS and RS in comparison with OSA-SPS as OSA concentration was beyond 6%. HMT decreased swelling power of starch while OSA modification had a contrary role (pâ¯<â¯0.05). Scanning electron microscopy (SEM) showed starch was destroyed by OSA modification while HMT had slight effect on the structure. X-ray diffraction (XRD) indicated that crystal type of starch was transformed from C- to A-type resulted from HMT, and remained unchanged by OSA modification. The onset, peak, and conclusion gelatinization temperatures of starch increased by HMT and decreased by OSA modification (pâ¯<â¯0.05).

CONTEXT: Our previous biological study demonstrated that Fructus Ligustri Lucidi (FLL), the fruit of Ligustrum lucidum Ait. (Oleaceae), could be used to maintain calcium balance and prevent age-related osteoporosis since it effectively decreased calcium loss and increased calcium retention in rats. OBJECTIVE: This study investigates the combination effect of the Chinese herbal medicine FLL and a high calcium diet on calcium imbalance induced by ovariectomy in mice. MATERIALS AND METHODS: The ovariectomized (OVX) mice were orally treated with vehicle, FLL extract (700 mg/kg), milk powder (5 g/mice) fortified with calcium (1.0% Ca) and the combination of FLL with milk powder. After 6 weeks of treatment, urine, serum, and tibia were preserved for biochemical analysis and kidneys were taken for gene expression analysis. RESULTS: The combination treatment of FLL and a high calcium diet significantly increased bone calcium content (6.80 ± 0.34 mg) by 22% (p < 0.05) and decreased urine calcium excretion (0.099 ± 0.009 mg/mg) by 62% (p < 0.01) as compared with those of the OVX group (bone Ca, 5.57 ± 0.31 mg; urine Ca/Cr, 0.261 ± 0.017 mg/mg). The mRNA expression of renal calcium-binding protein-9k (CaBP-9k) and calcium-sensing receptor (CaSR) in combination treatment group was significantly up-regulated and down-regulated, respectively, as compared with those of the OVX group. CONCLUSION: The beneficial effects of this combination therapy on calcium balance of OVX mice were, at least partially, attributed to its regulation on mRNA expression of CaBP-9k and CaSR in kidney.

OBJECTIVE: To compare the intervention effects of four traditional Chinese medicines (TCMs) with typical cold or hot property on body temperature and temperature-sensitive transient receptor potential ion channel proteins (TRPs) of rats with yeast-induced fever. METHOD: The pyrexia model was induced by injecting yeast suspension subcutaneously. Totally 108 male SD rats were randomly divided into the normal group, the model group, the Rhei Radix et Rhizoma treated group, the Coptidis Rhizoma treated group, the Euodiae Fructus treated group, and the Alpiniae Officinarum Rhizoma treated group, with 18 rats in each group. At the 4 h, 8 h and 12 h after injection of yeast, the rats were sacrificed to collect their hypothalamus and dorsal root ganglion. The expressions of TRPV1 and TRPM8 were detected by immunohistochemistry and Western blot method. RESULT: Compared with the normal group, after injection of yeast, the temperature of rats in the model group notably increased, and reached the peak at 8 h (P < 0.01). The TRPV1 level in hypothalamus and dorsal root ganglia (DRG) of the model group significantly increased, whereas the TRPM8 level significantly reduced. Compared with the model group, the Rhei Radix et Rhizoma group and the Coptidis Rhizoma group showed significant decrease in the high body temperature of rats caused by yeast, down-regulation in the expression of TRPV1, and up-regulation in the expression of TRPM8 (P < 0.05 or P < 0.01). Euodiae Fructus and Alpiniae Officinarum Rhizoma had no significant effect on either temperature or TRPs of fever rats. CONCLUSION: Rhei Radix et Rhizoma and Coptidis Rhizoma, both are TCMs with cold property, can reduce the temperature of fever rats induced by yeast, which may be related to their effective regulation of TRPV1 and TRPM8 in hypothalamus and DRG, while Euodiae Fructus and Alpiniae Officinarum Rhizoma had no relevant effect.

OBJECTIVE: To investigate the therapeutic effect of Anti-anaphylaxis Granule (AAG) on chronic urticaria and its impact on cytokine of regulated upon activation of normal T cells expressed and secreted (RANTES), eosinophil chemotactic factor (Eotaxin) and tumor necrosis factor-alpha (TNF-alpha). METHODS: The therapeutic effects of AAG and cetirizine on chronic urticaria patients allocated in two groups were observed respectively, and the serum levels of RANTES, Eotaxin and TNF-alpha in patients were measured by ELISA before and after treatment, and were compared with those in normal subjects. RESULTS: The therapeutic effects of AAG group were better in effective rate (88.5% vs 64.0%) and lower in the recurrent rate (5.6% vs 41.9%) than those cetirizine (all P<0.05). Serum levels of RANTES, Eotaxin and TNF-alpha in patients were higher than those in normal subjects (P<0.01), and they could be significantly reduced after AAG treatment (P<0.01). CONCLUSION: AAG has favorite effect for treatment of chronic urticaria, its regulation on serum levels of RANTES, Eotaxin and TNF-alpha may be the mechanism of action.

OBJECTIVE: To explore the relationship of Pi-deficiency syndrome in TCM with the change of serum high density lipoprotein (HDL) in blood lipid metabolic disorder. METHODS: Sixty-eight patients with confirmed coronary heart disease (CHD) were selected for TCM syndrome typing into Pi-deficiency (PD) group and non-Pi-deficiency (NPD) group. Routine blood lipids and serum lipoprotein electrophoretogram (SLPG) were determined in all patients to analyze the total content of HDL and its relative contents of sub-components HDL(1-5), as well as their relation with PD syndrome. Besides, a healthy control group (62 cases) was set up. RESULTS: The level of serum HDL-C was lowered, SLPG abnormality rate increased in the patients with CHD, with total HDL and the relative contents of subcomponent HDL(1) and HDL(3) significantly lower than those in the healthy control group (P<0.01). The total HDL, HDL(1) and HDL(3) in the PD group were also lower than those in the NPD group (P<0.05, P<0.01). CONCLUSION: Serum HDL and its sub-components showed a definite relation with TCM PD syndrome type, therefore, further exploring the granular specificity of HDL and its sub-components as well as their influence on reverse cholesterol transport (RCT) may hopefully provide clues for developing RCT regulatory Chinese new drugs and for CHD prevention and treatment.
