Association of vitamins B1 and B2 intake with early-onset sarcopenia in the general adult population of the US: a cross-sectional study of NHANES data from 2011 to 2018.

Background: Early-onset sarcopenia refers to the progressive loss of muscle mass and function that occurs at an early age. This condition perpetuates the vicious cycle of muscle loss and is associated with adverse outcomes. It is important to identify the contributing factors for early intervention and prevention. While diet is known to impact muscle mass, the association of B vitamins with early-onset sarcopenia remains unexplored. Objectives: To investigate the association of B vitamins intake with early-onset sarcopenia risk in a cross-sectional study. Methods: We conducted data analysis on a total of 8,711 participants aged between 20 and 59 years who took part in the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018. Early-onset sarcopenia was defined as a SMI measured by DXA that was one standard deviation below the sex-specific mean of the reference population. B vitamins intake (B1, B2, B3, B6, B9, and B12) was assessed by 24-h dietary recall. We used weighted multiple logistic regression and RCS models to estimate the OR and 95% CI of sarcopenia by B vitamins intake, adjusting for demographic, physical, lifestyle, comorbidities, and nutritional covariates. Results: Higher intake of vitamin B1 was associated with a 22% lower sarcopenia risk (OR = 0.78, CI = 0.63-0.97, p = 0.022), and higher intake of vitamin B2 with a 16% lower risk (OR = 0.84, CI = 0.74-0.97, p = 0.012) in both genders. Gender-specific analyses showed a 28% reduction in sarcopenia risk among males with each additional mg of vitamin B1 intake (OR = 0.72, CI = 0.52-0.97, p = 0.038), and a 26% decrease among females with each additional mg of vitamin B2 intake (OR = 0.74, CI = 0.57-0.96, p = 0.021). No significant differences were found between vitamin B2 and males, or between vitamin B1 and females. The RCS model suggested a nonlinear relationship between vitamin B2 intake and sarcopenia risk (POverall = 0.001, PNonlinear = 0.033), with a plateau effect above 3 mg/d. Conclusion: Higher intake of vitamin B1 and B2 may lower the risk of early-onset sarcopenia, with gender differences. This suggests the potential of nutritional intervention by increasing these vitamins intake through diet and supplements. Further research is warranted to elucidate the mechanisms and design targeted interventions.

Efficacy of Ganshuang granules on non-alcoholic fatty liver and underlying mechanism: a network pharmacology and experimental verification.

OBJECTIVE: To investigate the potential pharmacological mechanisms of Ganshuang granules (, GSG) in treating non-alcoholic fatty liver (NAFLD). METHODS: All the active components and targets of GSG were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform. Protein-Protein interaction network, Kyoto Encyclopedia of Genes and Genomes and Gene Ontology function annotation of common targets were analyzed to predict the mechanisms of action of GSG in the treatment of NAFLD. Then, the mouse models of NAFLD were constructed in a diet-induced manner and treated with GSG. The levels of interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α) and phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) pathway-related proteins in the liver of mice in each group were measured by enzyme linked immunosorbent assay and Western blot, respectively. RESULTS: Network pharmacology revealed a total of 159 potential targets of GSG for the treatment of NAFLD. Functional enrichment analysis indicated that the PI3K/AKT signaling pathway may be involved during GSG treatment of NAFLD. Further experiments showed that the significantly decreased alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total cholesterol, triglyceride and low-density lipoprotein cholesterol levels in NAFLD model mice serum after GSG treatment, as well as the expression levels of IL-6 and TNF-α in the liver. Furthermore, drug intervention increased the protein expression levels of phosphorylated-PI3K (P-PI3K) and P-AKT in the liver of the model group mice, and decreased the protein expression level of sterol regulatory element-binding protein 1. CONCLUSION: We found that GSG is effective in treating NAFLD and the potential therapeutic targets may be involved in PI3K/AKT signaling pathway.

Efficacy of luteolin on the human gastric cancer cell line MKN45 and underlying mechanism.

OBJECTIVE: To investigate the antitumour efficacy of luteolin on gastric cancer (GC) and study the mechanism underpinning the action. METHODS: Effects of luteolin on cell growth inhibition, apoptosis, and cell cycle arrest in MKN45 cells were investigated using the cell counting kit-8 assay. Changes in the mitochondrial membrane potential after luteolin treatment were assessed using 5,5',6,6'-tetra-chloro-1,1',3,3'-tetraethylbenzimidazolcarbocyanineiodi-de (JC-1) staining. To investigate whether apoptotic effect by luteolin is related to the phosphoinositide 3-kinase/v-akt murine thymoma viral oncogene (PI3K/Akt) pathway, cells were additionally treated with LY294002, a PI3K/Akt pathway inhibitor. Moreover, the expressions of apoptosis-related proteins, namely B-cell lymphoma 2(Bcl-2), Bcl-2 associated X protein (Bax), Akt, p-Akt, caspase-3, and cytochrome C, were detected after luteolin treatment. RESULTS: The study revealed that in MKN45 cells, luteolin could inhibit the cell proliferation in a time- and dose-dependent manner; block the cell cycle in the S-phase; induce apoptosis; reduce the mitochondrial membrane potential; increase the expression of Bax, caspase-3, and cytochrome C; and decrease the expression of Bcl-2 and p-Akt. Luteolin might be involved in the PI3K/Akt signalling pathway, indicating that this pathway could be a therapeutic target for GC treatment. CONCLUSION: Luteolin could inhibit the proliferation of GC cells and block the cell cycle in the S-phase. The mechanism of inducing apoptosis in these cells was related to the PI3K/Akt signalling pathway.

It has become a common consensus that resource conservation and intensive recycling for improving resource utilization efficiency is an important way to achieve carbon peak and carbon neutrality(dual carbon). Traditonal Chinese medicine(TCM)resources as national strategic resources are the material basis and fundamental guarantee for the development of TCM industry and health services. However, the rapid growth of China's TCM industry and the continuous expansion and extension of the industrial chain have exposed the low efficiency of TCM resources. Resource waste and environmental pollution caused by the treatment and discharge of TCM waste have emerged as major problems faced by the development of the industry, which has aroused wide concern. Considering the dual carbon goals, this paper expounds the role and potential of TCM resource recycling and circular economy industry development. Taking the typical model of TCM resource recycling as the case of circular economy industry in reducing carbon source and increasing carbon sink, this paper puts forward the suggestions for the TCM circular economy industry serving the double carbon goals. The suggestions mainly include strengthening the policy and strategic leading role of the double carbon goals, building an objective evaluation system of low-carbon emission reduction in the whole industrial chain of TCM resources, building an industrial demonstration park for the recycling of TCM resources, and promoting the establishment of a circular economy system of the whole industrial chain of TCM resources. These measures are expected to guide the green transformation of TCM resource industry from linear economic model to circular economy model, provide support for improving the utilization efficiency and sustainable development of TCM resources, and facilitate the low-carbon and efficient development of TCM resource industry and the achievement of the double carbon goals.

It also overviewed the applications of Chinese medicinal residue in feed additives, organic fertilizers, edible mushroom cultivation substrates, preparation of activated carbon for wastewater treatment, and new energy batteries. Considering the current status of resource utilization of Chinese medicinal residues, feasible strategies and suggestions for resource development and utilization were proposed to improve the quality and efficiency of the Chinese medicinal resource industry chain and promote green development, thereby providing research ideas and theoretical basis for achieving carbon peak and carbon neutrality goals.

Biomimetic metalloporphyrin oxidase modified carbon nanotubes for highly sensitive and stable quantification of anti-oxidants tert-butylhydroquinone in plant oil.

This study constructed a novel biomimetic enzyme electrochemical biosensor based on tetraphenyl metalloporphyrins functionalized multi-walled carbon nanotubes (MWCNTs). The effect of central metal ions on the catalytic activity of tetraphenyl metalloporphyrin biomimetic enzyme was investigated. It was found that the change of central metal ions had a significant effect on the catalytic performance of metalloporphyrin and Zinc(II) tetraphenylporphyrin (ZnTPP) had the most excellent catalytic property. The electrochemical behaviors of tert-butylhydroquinone (TBHQ) on ZnTPP/MWCNTs modified electrode were investigated. It was found that the redox peak current was increased significantly, which was attributed to the redox peak current to the electrocatalytic activity of ZnTPP and the synergistic effect between ZnTPP and MWCNTs. A strong linear relationship was shown in the concentration range of 0.01 to 1000 µM. This electrochemical sensor also had excellent repeatability, storage, and interference resistance. This work provided a simple and sensitive method for the determination of TBHQ.

Effects of Nardostachys jatamansi on gut microbiota of rats with Parkinson's disease / 中国中药杂志

Under the guidance of the traditional Chinese medicine(TCM) theory of "Zangfu-organs of spleen and stomach" and the modern theory of "microbiota-gut-brain axis", this study explored the effects of Nardostachys jatamansi on the gut microbiota of rats with Parkinson's disease(PD). The 40 SD rats were randomly divided into the control group, PD model group, levodopa group, and Nardostachys jatamansi ethanol extract group. The PD model was established by subcutaneous injection of rotenone in the neck and back area. After 14 days of intragastric administration, the PD rats' behaviors were analyzed through open field test, inclined plane test, and pole test. After the behavioral tests, the striatum, colon, and colon contents of rats in each group were collected. Western blot was employed to detect the protein expression of tyrosine hydroxylase(TH) and α-synuclein(α-syn) in striatum and that of α-syn in colon. Enzyme linked immunosorbent assay(ELISA) was used to detect the levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), and nuclear factor-kappa B(NF-κB) in striatum and colon. High-throughput sequencing of 16 S rRNA gene was conducted to detect the differences in microbial diversity, abundance, differential phyla, and dominant bacteria of rats between groups. The results indicated that Nar. ethanol extract could relieve dyskinesia, reverse the increased levels of α-syn, TNF-α, IL-1β, and NF-κB in striatum, and improve the protein expression of TH in striatum of PD rats. The α diversity analysis indicated a significant decrease in diversity and abundance of gut microbiota in the PD model. The results of linear discriminant analysis effect size(LEfSe) of dominant bacteria indicated that Nardostachys jatamansi ethanol extract increased the relative abundance of Clotridiaceae, Lachnospiraceae, and Anaerostipes, and reversed the increased relative abundance of Proteobacteria, Gammaproteobacteria, Enterobacteriaceae, and Escherichia-Shigella in PD model group to exhibit the neuroprotective effect. In summary, the results indicated that Nar. ethanol extract exert the therapeutic effect on PD rats. Specifically, the extract may regulate gut microbiota, decrease the levels of proinflammatory cytokines, and reduce the protein aggregation of α-syn in the colon and striatum to alleviate intestinal inflammation and neuroinflammation. This study provides a basis for combining the theory of "Zangfu-organs of spleen and stomach" with the theory of "microbiota-gut-brain axis" to treat PD.

Self-designed general information questionnaire, inflammatory bowel disease questionnaire (IBDQ), readiness for hospital discharge scale (RHDS), mindful attention awareness scale (MAAS), hospital anxiety and depression scale and Pittsburgh sleep quality index (PSQI) were used to conduct questionnaire surveys in patients. Factors influencing the quality of life of CD patients were analyzed. Mann-Whitney U test and independent sample t test were used for the comparison between two groups; Kruskal-Wallis H test and one-way analysis of variance were used for comparison between multiple groups; Pearson analysis was used for correlation analysis, and multiple linear regression method was used for multivariate analysis. Results:The results of univariate analysis showed that the quality of life was poor in CD patients with spouse, primary school education or below, living in cities, sleep disorders, anxiety, depression, and severe activity. The total IBDQ scores were lower than those with no spouse, junior high school to senior high school and above, living in villages and towns, no sleep disorders, no anxiety, no depression, and in remission and mild to moderate activity (46.23±29.77 vs. 117.45±42.23; 11.00 (6.25, 30.75) vs. 79.00 (56.00, 113.00) and 114.00 (72.50, 157.50); 37.12±30.67 vs. 69.43±24.78 and 126.76±41.54; 42.67±23.18 vs. 124.58±36.52; 50.35±27.23 vs. 122.42±42.41; 51.97±37.29 vs. 113.96±44.18; 11.00 (6.75, 18.00) vs. 154.00 (135.50, 164.50), 97.00(79.00, 112.00) and 49.00(36.75, 62.25)), and the differences were statistically significant ( t=-14.40, H=60.56, F=117.61, t=-20.17, -15.20 and -10.87, and H=148.98; all P<0.001). The results of correlation analysis showed that the RHDS score was positively correlated with the scores of each dimension and total scores of IBDQ ( r=0.646 to 0.781, all P<0.001); the MAAS score was positively correlated with the scores of each dimension and total scores of IBDQ ( r=0.331 to 0.382, all P<0.001). The results of multiple linear regression analysis demonstrated that readiness for hospital discharge, level of mindful attention awareness, education level, place of residence, sleep disorders, whether with anxiety and disease activity were the influencing factors of the quality of life of CD patients ( t=4.19, 5.38, 2.36, 2.88, 2.85, 3.11 and -7.22, all P<0.05). Conclusions:The quality of life is poor in CD patients with primary school education or below, live in cities, sleep disorders, anxiety, severe activity, low readiness for hospital discharge and low level of mindful attention awareness. Doctors and nurses should pay attention to these patients and improve their quality of life.

Participants with mixed haemorrhoids from Xiyuan Hospital of China Academy of Chinese Medical Sciences, Beijing Rectum Hospital, Air Force Medical Center of People's Liberation Army of China, and Puyang Hospital of Traditional Chinese Medicine were enrolled from September 2016 to March 2018. By using a blocked randomization scheme, participants were assigned to two groups. The experimental group was treated with HSLI, while the control group was treated with Milligan-Morgan haemorrhoidectomy. The primary outcome was the clinical effect evaluated at 12 weeks after operation. The secondary outcomes included the number of haemorrhoids treated during the operation, pain scores, use of analgesics, postoperative oedema, wound healing, incidence of anal stenosis, anorectal manometry after operation, as well as surgical duration, length of stay and total hospitalization expenses. A safety evaluation was also conducted. RESULTS: In total, 246 eligible participants were enrolled, with 123 cases in each group. There was no significant difference in the clinical effect between the two groups (100.00% vs. 99.19%, P>0.05). Compared with the control group, the number of external haemorrhoids treated during the operation and the pain scores after operation were significantly reduced in the experimental group (P<0.05 or P<0.01); the patient number with wound healing at 2 weeks after operation and the functional length of anal canal at 12 weeks after operation were significantly increased in the experimental group (P<0.05). There was no significant difference in the incidence of anal stenosis, the numbers of patients using analgesics and patients with postoperative oedema between the two groups after operation (P>0.05). The surgical duration and length of stay in the experimental group were significantly longer than those in the control group, and the total hospitalization expense was significantly higher than that in the control group (all P<0.05). No adverse events were reported in either group during the whole trial or follow-up period. CONCLUSION: HSLI had the advantages of preserving the skin of anal canal completely, alleviating postsurgical pain and promoting rapid recovery after operation. (Registration No. ChiCTR1900022883).

Effects of anode materials on the performance and anode microbial community of soil microbial fuel cell.

Five soil microbial fuel cells (SMFCs) with graphite felt, aluminium sheet, activated carbon fibre felt, graphite paper and carbon cloth as anodes were constructed using the petroleum hydrocarbon polluted soils as substrates. After 115 days of operation, the SMFC with graphite felt anode performed the best in both bioelectricity output and removal of target pollutants, with the bioelectricity output parameters of 345 mV for stable voltage, 24.0 mW/m2 for power density and 774 Ω for internal resistance, and the removal rates of 59.14 % for total petroleum hydrocarbon, 61.65 % for anthracene, and 55.92 % for pyrene, respectively. The conductivity of the material was the key factor affecting the electron transfer rate of the anode, which determined the electric acclimation and screening intensity of SMFC to soil microbes, leading to the growth and succession of the electricigens-dominanted anode microbial community with various abundances of phyla and genera. The surface structure of the anode material played a critical role in the internal resistance of SMFC through affecting the mass transfer of substrate and metabolites, and it might also change the abundance of microbes especially those non-electricigens on the community through different adhesion.

Textual Research of Classical Prescription Taohong Siwutang / 中国实验方剂学杂志

Taohong Siwutang， originating from Fuke Bingjian by CHAI Dehua in the Qing Dynasty， has been included in the first batch of the 100 classical prescriptions published by the National Administration of Traditional Chinese Medicine（TCM）. Taohong Siwutang is composed of six Chinese medicinals， namely the wine-washed Angelicae Sinensis Radix， wine-washed Rehmanniae Recens Radix， wine-washed Carthami Flos， wine-processed Paeoniae Alba Radix， Persicae Semen undergoing peel-off process in hot water， and Chuanxiong Rhizoma， possessing the effects of nourishing blood， promoting blood circulation， and removing blood stasis， and it is mainly applicable to patients with blood deficiency and stasis syndrome. The textual research on the key information of classical prescriptions and the summarization of their ancient and modern applications are conducive to learning about the research status and confirming the subsequent research direction， thus better guiding the preparation of substance benchmarks and the in-depth exploration of preparations. By exploring the sources and historic evolution of Taohong Siwutang and each Chinese medicinal， this paper uncovered the prescription composition， origin of each Chinese medicinal， processing method， and prescription dose. The review of its clinical applications showed that the application scope in modern times has been extended and expanded in contrast to that recorded in ancient books. As revealed by the clinical application literature， it has been mainly employed for treating gynecological diseases such as dysmenorrhea and irregular menstruation， orthopedic diseases like fracture， dermatological diseases such as chloasma， and internal diseases such as coronary heart disease， all of which were differentiated into the blood deficiency and stasis syndrome. It could be seen that Taohong Siwutang had great clinical application value. This review of the ancient and modern literature concerned with Taohong Siwutang and the analysis and determination of its key information are expected to provide a reference for the rational clinical application and further research of Taohong Siwutang.
