JOURNAL OF INTEGRATIVE MEDICINE 2022; 20:173-181. [PMID: 35101368 DOI: 10.1016/j.joim.2022.01.004] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Accepted: 12/15/2021] [Indexed: 01/23/2023]
Abstract
OBJECTIVE This study was done to determine the effects of different courses of moxibustion on a rat knee osteoarthritis (KOA) model, and explore the dose-effect relationship of moxibustion on KOA from the perspectives of intestinal flora and inflammatory factors. METHODS Wistar rats were randomly divided into five groups: normal, model, moxibustion for 2 weeks, moxibustion for 4 weeks and moxibustion for 6 weeks groups (n = 5 each group). A KOA rat model was induced by monosodium iodoacetate, and moxibustion intervention was performed at the acupoints "Dubi" (ST35) and "Zusanli" (ST36), once every other day. Pathologic changes in the cartilage of rat knee joints were assessed after intervention, and fecal samples were subjected to 16S rRNA high-throughput sequencing for microbial diversity analysis. RESULTS Damage to the knee articular cartilage was obvious in the model group, which also had increased levels of pro-inflammatory factors, decreased levels of anti-inflammatory factors, and intestinal flora disorders with decreased diversity. The degree of cartilage damage in the 4 and 6 weeks of moxibustion groups was significantly improved compared with the model group. The 4 and 6 weeks of moxibustion groups also demonstrated reduced levels of interleukin-1β and tumor necrosis factor-α and increased levels of interleukin-10 (P < 0.05). Both the abundance and diversity of the intestinal flora were increased, approaching those of the normal group. Abundances of probiotics Eubacterium coprostanoligenes group and Ruminococcaceae UCG-014 increased, while that of the pathogenic bacteria Lachnospiraceae NK4A136 group decreased (P < 0.05). Although the abundance of Lachnospiraceae NK4A136 group decreased in the 2 weeks of moxibustion group compared with the model group (P < 0.05), there was no statistically significant difference in serum inflammatory factors, flora species diversity or degree of pathological damage compared with the model group. CONCLUSION Moxibustion treatment led to significant improvements in the intestinal flora and inflammatory factors of rats with KOA. Moxibustion treatment of 4 and 6 weeks led to better outcomes than the 2-week course. Moxibustion for 4 and 6 weeks can regulate intestinal flora dysfunction with increased probiotics and reduced pathogenic bacteria, reduce pro-inflammatory factors and increase anti-inflammatory factors. No significant differences were seen between the effects of moxibustion for 4 weeks and 6 weeks.

Abstract
Chlorination disinfection byproducts (CDBPs) can exert adverse human health effects. Many toxicology-based studies confirmed the health hazards of CDBPs, but little research has been done on gut microbiome. We explored the effect of CDBPs on intestinal microbiota in the Simulator of the Human Intestinal Microbial Ecosystem (SHIME). The results showed that CDBPs slightly inhibited the production of short-chain fatty acids, and the abundance of Actinobacteria decreased in the transverse colon and descending colon. The abundance of Proteobacteria increased in the ascending colon and descending colon, while it decreased in the transverse colon. The abundance of Firmicutes decreased in both the ascending colon and descending colon. In particular, the abundance of Lachnospiraceae members, Bilophila, Oscillospira, Parabacteroides, Desulfovibrio, and Roseburia increased in the ascending colon, while the abundance of Sutterella, Bacteroides, Escherichia, Phascolarctobacterium, Clostridium, Citrobacter, and Klebsiella increased in the descending colon. The Shannon index differed significantly in both the ascending colon and descending colon before and after exposure. Overall, we demonstrate the feasibility of applying the SHIME model to studying the effects of intestinal toxicity on health of chlorinated by-products. The findings of this study improve our understanding of the health impact of CDBPs on the intestinal microbiota and better control of CDBPs in treated water is recommended.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 96:153906. [PMID: 35026522 DOI: 10.1016/j.phymed.2021.153906] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 12/09/2021] [Accepted: 12/21/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Osteoarthritis (OA), a common joint disorder with an increasing incidence worldwide, severely affects the quality of life of patients. In Chinese herbal medicine, Abrus cantoniensis Hance is considered to exert protective effects on the liver and to have beneficial effects on the gallbladder; additionally, it has antibacterial and anti-inflammatory properties, as well as the ability to enhance immunity, scavenge free radicals, regulate smooth muscle function, and improve endurance. Abrine extracted from A. cantoniensis Hance has been reported as a main functional compound capable of treating chronic inflammation. PURPOSE In this study, we explored the effect of abrine on OA progression. STUDY DESIGN Bioinformatics analysis was performed on abrine and its potential targets in OA, using the Comparative Toxicogenomics Database, GSE1919 dataset from the Gene Expression Omnibus database, Gene Set Enrichment Analysis, and docking interaction analysis. METHODS The effect of abrine in vitro was analysed by Cell Counting Kit 8 assays, colony formation assays, enzyme-linked immunosorbent assay, flow cytometry analysis, quantitative real-time PCR, and western blotting using human transformed chondrocyte cell line C28/I2. The effect of abrine was evaluated in vivo using the anterior cruciate ligament transection (ACLT) Sprague-Dawley rat OA model. RESULTS Abrine enhanced the proliferation of interleukin (IL)-1β-stimulated C28/I2 cells in a dose-dependant manner. Expression of pro-inflammatory cytokines was induced by IL-1β treatment, whereas abrine treatment repressed the induction of C28/I2 cells in a dose dependant manner (p < 0.05). Abrine induced cell proliferation and inhibited apoptosis in IL-1β-stimulated C28/I2 cells (p < 0.05). Abrine also inhibited Proviral Integrations of Moloney virus 2 (PIM2) expression in IL-1β-stimulated C28/I2 cells (p < 0.05). The expression of vascular endothelial growth factor (VEGF), p-VEGFR2, and p-eNOS was induced by IL-1β treatment in C28/I2 cells, while abrine inhibited this induction in a dose dependant manner. Treatment with abrine decreased the expression levels of PIM2 and VEGF in IL-1β-stimulated C28/I2 cells (p < 0.05). Overexpression of PIM2 induced cell proliferation and inhibited apoptosis in IL-1β-stimulated C28/I2 cells, while VEGF silencing reversed this effect (p < 0.05). Finally, abrine prevented cartilage degradation in the ACLT model. CONCLUSION We demonstrated that abrine promoted cell proliferation and inhibited apoptosis in IL-1β-stimulated C28/I2 cells through PIM2/VEGF signalling. These findings indicate PIM2 to be a potential drug target. Moreover, abrine has potential applicability as a therapeutic agent against OA.

Abstract
Osteoarthritis (OA) is the most prevalent joint disease worldwide, making it a major cause of pain and disability. Identified as a chronic and progressive disease, effective treatment at the early stages of OA has become critical to its management. Jintiange (Jtg) capsules are a traditional Chinese medicine produced from multiple organic components of various animal bones and routinely used to treat osteoporosis in China. However, the effect of Jtg on subchondral bone and cartilage degeneration in OA remains unknown. The purpose of the present study was to investigate the biomolecular role and underlying mechanisms of Jtg in OA progression. Herein, we found that Jtg inhibited receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast formation and it functions through the NF-κB signaling pathway. Jtg also inhibited chondrocyte apoptosis via reducing the reactive oxygen species concentration in these cells. Moreover, in vivo evaluation revealed that Jtg significantly attenuates subchondral bone remodeling and cartilage destruction in anterior cruciate ligament transection (ACLT) mouse models. Taken together, our data demonstrate that Jtg inhibits osteoclast differentiation in subchondral bone and chondrocyte apoptosis in cartilage, supporting its potential therapeutic value for treating OA.

[PMID: 34641785 PMCID: PMC8513338 DOI: 10.1186/s12014-021-09330-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 09/29/2021] [Indexed: 08/30/2023] Open
Abstract
Background Osteoporosis (OP) is a systemic bone disease characterized by decreased bone mass, destruction of the bone tissue microstructure, increased bone brittleness and an increased risk of fracture. OP has a high incidence rate and long disease course and is associated with serious complications. Yigu decoction (YGD) is a compound prescription in traditional Chinese medicine that is used to treat OP. However, its mechanism in OP is not clear. This study used a tandem mass tag (TMT)quantitative proteomics method to explore the potential bone-protective mechanism of YGD in an osteoporotic rat model. Materials and methods A rat model of OP was established by ovariectomy. Eighteen 12-week-old specific-pathogen-free female Wistar rats weighing 220 ± 10 g were selected. The eighteen rats were randomly divided into 3 groups (n = 6 in each group): the normal, model and YGD groups. The right femurs from each group were subjected to quantitative biological analysis. TMT quantitative proteomics was used to analyze the proteins extracted from the bone tissue of rats in the model and YGD groups, and the differentially expressed proteins after intervention with YGD were identified as biologically relevant proteins of interest. Functional annotation correlation analysis was also performed to explore the biological function and mechanism of YGD. Result Compared with the model group, the YGD group showed significant upregulation of 26 proteins (FC > 1.2, P < 0.05) and significant downregulation of 39 proteins (FC < 0.833, P < 0.05). Four important targets involved in OP and 5 important signaling pathways involved in bone metabolism were identified. Conclusions YGD can significantly increase the bone mineral density (BMD) of osteoporotic rats and may play a therapeutic role by regulating target proteins involved in multiple signaling pathways. Therefore, these results improve the understanding of the OP mechanism and provide an experimental basis for the clinical application of YGD in OP treatment.

Co-exposure to fluoride and arsenic disrupts intestinal flora balance and induces testicular autophagy in offspring rats. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2021; 222:112506. [PMID: 34265531 DOI: 10.1016/j.ecoenv.2021.112506] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 07/06/2021] [Accepted: 07/07/2021] [Indexed: 06/13/2023]
Abstract
While numerous studies have shown that fluoride or arsenic exposure may damage the reproductive system, there are few reports of co-exposure to fluoride and arsenic. In addition, the literature on autophagy and intestinal flora composition in reproductive toxicity studies of co-exposure to fluoride and arsenic is insufficient. In this study, we developed a rat model of fluoride and arsenic exposure via drinking water from pre-pregnancy to 90 days postnatal. Sprague-Dawley rats were randomly divided into sterile water control group, fluoride group (100 mg/L NaF), arsenic group (50 mg/L NaAsO2) and combined exposure group (100 mg/L NaF+50 mg/L NaAsO2). Our results showed that fluoride and arsenic exposure caused a reduction in testicular weight and significant pathological damage to tissue. We found that the levels of follicle-stimulating hormone, luteinizing hormone, and testosterone were reduced to varying degrees. Meanwhile experiments showed that fluoride and arsenic exposure can modulate autophagic flux, causing increased levels of Beclin1 and LC3 expression and decreased p62 expression. Analogously, by performing 16S sequencing of rat feces, we found 24 enterobacterial genera that differed significantly among the groups. Furthermore, the flora associated with testicular injury were identified by correlation analysis of hormonal indices and autophagy alterations with intestinal flora composition at the genus level, respectively. In summary, our study shows that fluoride and arsenic co-exposure alters autophagic flux in the testis, causes testicular injury, and reveals an association between altered intestinal flora composition and testicular injury.

Abstract
Coronavirus Disease 19 (COVID-19) is a respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has grown to a worldwide pandemic with substantial mortality. The symptoms of COVID-19 range from mild flu-like symptoms, including cough and fever, to life threatening complications. There are still quite a number of patients with COVID-19 showed enteric symptoms including nausea, vomiting, and diarrhea. The gastrointestinal tract may be one of the target organs of SARS-CoV-2. Angiotensin converting enzyme 2 (ACE2) is the main receptor of SARS-CoV-2 virus, which is significantly expressed in intestinal cells. ACE2 links amino acid malnutrition to microbial ecology and intestinal inflammation. Intestinal flora imbalance and endotoxemia may accelerate the progression of COVID-19. Many herbs have demonstrated properties relevant to the treatment of COVID-19, by supporting organs and systems of the body affected by the virus. Herbs can restore the structure of the intestinal flora, which may further modulate the immune function after SARS-CoV-2 infection. Regulation of intestinal flora by herbal medicine may be helpful for the treatment and recovery of the disease. Understanding the role of herbs that regulate intestinal flora in fighting respiratory virus infections and maintaining intestinal flora balance can provide new ideas for preventing and treating COVID-19.
