Furthermore, pretreatment prominently (P less then 0.05) enhanced propulsive movement of the gastrointestinal tract in normal mice and mice with gastrointestinal motility disorders. CONCLUSION Ethanol extracts of RA ameliorated gastric lesions in the gastric ulcer rat model. The mechanisms of action were related to improvement of gastrointestinal dynamics, maintenance of mucus integrity, and inhibition of apoptosis by downregulating proapoptotic Bax protein and upregulating anti-apoptotic Bcl-2 protein.OBJECTIVE To explore the protective mechanisms of the Traditional Chinese Medicine Bushenhuoxue (BSHX) in a rat model of vascular dementia (VD). METHODS A rat model of VD was developed using bilateral common carotid artery occlusion (BCCAO). Rats were administered BSHX (10.14 or 5.07 g/kg), nimodipine (11.06 mg/kg; positive control), or saline (control) by gavage daily for 30 d post-surgery. Learning and memory abilities were assessed using the Morris water maze. Morphological changes in the hippocampus were observed using light microscopy (hematoxylin and eosin staining) and transmission electron microscopy (TEM). The mRNA and protein expression levels of brain-derived neurotrophic factor (BDNF), tyrosine receptor kinase B (TrkB), phosphatidyl inositol 3-kinase (PI3K), serine/threonine kinase (AKT), and cAMP response element binding protein (CREB) were measured by real-time polymerase chain reaction (RT-PCR) and Western blot, respectively. RESULTS Compared with the sham group, rats with BCCAO exhibited impaired learning and memory abilities (Morris water maze) and showed abnormalities in neuronal morphology (light microscopy) and ultrastructure (TEM) in the hippocampus. They also had decreased mRNA and protein expressions of BDNF, TrkB, PI3K, AKT, and CREB in hippocampal tissue (all P less then 0.05). In rats with BCCAO, administration of BSHX attenuated deficits in learning and memory, improved the morphology and ultrastructure of hippocampal neurons, and enhanced mRNA and protein expression levels of BDNF, TrkB, PI3K, AKT, and CREB (all P less then 0.05). CONCLUSION BSHX may protect hippocampal neurons and improve learning and memory abilities, at least in part via the activation of BDNF/TrkB/PI3K/AKT/CREB signaling.OBJECTIVE To observe the effects of the Bupi Hewei (BPHW) decoction on diarrhea and intestinal flora disorder induced by 5-fluorouracil (5-FU) and investigate the possible mechanism underlying these actions. METHODS Thirty-five male Sprague-Dawley rats were randomly divided into four groups normal control, 5-FU, 5-FU + BPHW decoction (10.5 g/kg for 5 consecutive days), and 5-FU + Bacillus licheniformis capsule groups (0.2 g/kg for 5 consecutive days). Animal models were established via the intraperitoneal injection of 5-FU (30 mg/kg for 5 consecutive days). At the end of the treatment period, diarrhea was assessed, and the change of the intestinal flora was examined using 16S rDNA high- throughput sequencing. Interleukin (IL)-17, IL-21, IL-6, IL-10, RAR-related orphan receptor gamma (RORγt), and forkhead box P3 (Foxp3) expression in the jejunum was detected using immunohistochemistry, quantitative real-time polymerase chain reaction (PCR), Western blotting, and enzyme- linked immuno sorbent assay. RESULTS In this study, the BPHW decoction effectively lowered the diarrhea score, increased the proportions of Bacteroidetes and Prevotellaceae-Alloprevotella species, and reduced the proportions of Proteobacteria, Escherichia-Shigella, Ruminococcaceae NK4A214, and Ruminococcaceae UCG-005 species in the rat intestine after 5-FU chemotherapy. In addition, the BPHW decoction significantly suppressed the expression of IL-17, IL-21, IL-6, IL-10, RORγt, and Foxp3 in the jejunum. CONCLUSION Our findings suggest that the BPHW decoction can improve the intestinal immune balance and reduce intestinal inflammation by targeting T helper cell/T regulatory cell-associated factors.OBJECTIVE To investigate the efficacy of Bushen Kangshuai (BS-KS) tablet on autophagy and polarization in mouse macrophage RAW 264.7. MEYHODS Macrophage autophagy was induced by oxidized low-density lipoprotein (100 μg/mL). To detect the levels of autophagy, macrophage were transfected with double fluorescence LC3 autophagy adenovirus, then the numbers of autophagosomes and autophagic lysosomes were asessed by confocal microscopy. The autophagy related proteins expression of PI3K, Akt, phospho-mAkt (p-Akt) and mTOR, phospho-mTOR ([p-TOR), p62, microtubule-associated protein 1 (LC3-Ⅱ)were determined by western blotting. The macrophage polarization model was induced by lipopolysaccharide (1 μg/mL). selleck kinase inhibitor The mRNA levels of iNOS, CD86 (M1 macrophages marker molecules), and CD206, Arg-1 (M2 macrophages marker molecules) were detected by real-time quantitative PCR. The concentration of cytokines TNF-α and IL-10 was determined by enzyme-linked immunosorbent assay. The protein expression of nuclear proteins PPAR-γ, NF-κB,nhibitory role in atherosclerosis.OBJECTIVE The aim of this study was to evaluate the effectiveness of Chinese herbal medicines for invigorating the kidney (CHMIK) on senile osteoporosis. METHODS We searched for studies in English-language databases (PubMed, the Cochrane Library, and Web of Science) and Chinese-language databases (China National Knowledge Infrastructure, Wan Fang Data, VIP Chinese periodical service platform, and China Biology Medicine disc from their inception to September 2017. Randomized controlled trials comparing the effectiveness of Traditional Chinese Medicine therapies (alone or in combination) and conventional clinical medicine therapies among older adult patients with osteoporosis were identified. We conducted a network Meta-analysis with a Bayesian hierarchical random-effects model using RStudio software, Version 3.4.1. RESULTS Forty-three randomized controlled trials assessing the differences between Traditional Chinese Medicine and conventional clinical medicine were identified, including 15 treatments and involving 3316 patients. The results of the network Meta-analysis indicated that alendronate (odds ratio [OR] = 0.20, 95% confidence interval [CI] 0.047-0.73) and calcium (OR = 0.18, 95% CI 0.11-0.30) are significantly more effective if combined with oral CHMIK. CHMIK alone is significantly more effective than both alendronate (OR = 0.34, 95% CI 0.10-1.0) and calcium (OR = 0.13, 95% CI 0.056-0.28). Moreover, CHMIK + tuina + calcium is more effective than CHMIK + calcium + vitamin D + alendronate (OR = 18.0, 95% CI 1.1-2.7e + 02). CONCLUSION The present network Meta-analysis found that alendronate and calcium are more effective if combined with oral CHMIK and that oral CHMIK alone may be more effective than alendronate or calcium. Tuina may have an advantage over oral medicines. Oral CHMIK and calcitonin show the most potential for treating senile osteoporosis.
