ObjectiveTo observe the effect and mechanism of Xiangsha Liujunzi decoction (XSLJZD) drug serum on gastric antrum smooth muscle cells (SMCs) in rats with functional dyspepsia (FD).MethodsGastric antrum SMCs from rats with FD were isolated, cultured, and then divided into six groups as follows: control, model, domperidone, low-dose XSLJZD (LXSLJZD), medium-dose XSLJZD (MXSLJZD), and high-dose XSLJZD (HXSLJZD). Each group was administered the corresponding drug serum for intervention. Drug serum intervention conditions and proliferative activity of SMCs were tested by cholecystokinin octapeptide. Ghrelin, gastrin, somatostatin, and substance P (SP) levels were measured by ELISA. Somatostatin and SP mRNA expression was measured by real-time PCR.ResultsA concentration of 10% drug serum for 24 h was decided to be the best intervention condition for later study. The mean optical density value in the model group was lower than that in the control group (P = .001). Optical density values in the domperidone and HXSLJZD groups were higher than those in the model group (P = .025, P = .032, respectively). Gastrin, SP, and ghrelin levels in the model group were lower (P = .007, P = .037, P = .005, respectively), but somatostatin levels were higher, compared with those in the control group (P = .031). Gastrin, SP, and ghrelin levels in the domperidone, MXSLJZD, and HXSLJZD groups were higher than those in the model group (all P<.05). Somatostatin levels in the four drug-treated groups were lower than those in the model group (P = .002, P = .007, P = .001, P = .009, respectively). SP mRNA levels in the model group were lower than those in the control, domperidone, MXSLJZD, and HXSLJZD groups (P = .037 P = .016, P = .025, P = .002, respectively). Somatostatin mRNA levels in the model group were higher than those in the control and MXSLJZD groups (P = .042, P = .035).ConclusionsXSLJZD and domperidone drug serum effectively promote proliferative activity of gastric antrum SMCs in an FD model. The mechanism of this activity may be regulated by gastrointestinal hormones. 相似文献

ObjectiveTo investigate the effects of Ganjiang granule (GG) on cecal microflora and serum biochemical components in rats with constipation-predominant irritable bowel syndrome (IBS–C).MethodsTwenty-four Sprague–Dawley rats were randomly divided into four groups: control, model, GG, and probiotics. Rats in the model, GG, and probiotics groups received 3 °C tap water intragastrically; rats in the GG group were treated with GG; rats in the probiotics group were treated with probiotics. For all rats, enzyme-linked immunosorbent assay and colorimetry were used to assess serum biochemical components related to gastrointestinal function; 16S rRNA high-throughput sequencing was used to analyze the cecal microflora.ResultsThe serum level of 5-hydroxytryptamine (HT) was higher in the model group than in the control group (Z = −2.082, P = .037). The model group exhibited changes in cecal microflora: the relative abundances of Lactobacillus decreased (Z = −2.882, P = .004) and Dorea increased (t = −3.030, P = .023), compared with the control group. The GG and probiotics groups exhibited normal serum levels of 5-HT. The GG and probiotics groups exhibited improved serum levels of gastrin; the probiotics group exhibited an improved serum level of vasoactive intestinal peptide. Compared with the model group, The GG group exhibited greater relative abundance of Ruminococcus (Z = −2.402, P = .016); the probiotics group exhibited greater relative abundance of SMB53 (Z = −2.823, P = .005) and lower relative abundances of Desulfovibrio (Z = −2.823, P = .005) and Facklamia (Z = −2.608, P = .009).ConclusionThe effects of GG on IBS-C may be related to regulation of the serum level of 5-HT, as well as elevated relative abundance of beneficial bacteria in cecal microflora. 相似文献

ObjectiveTo investigate the cardioprotective effect of Yiqi Huoxue granule (YQHXG) in the regulation of autophagy in rats induced with myocardial infarction (MI).MethodsAn acute MI animal model was established by ligation of the left anterior descending branch of the coronary artery in Sprague-Dawley rats. Besides, 20 rats received sham operation were classified into a control group. The remaining 59 rats were randomly divided into MI model group (n = 19), YQHXG group (n = 20), and perindopril group (n = 20). Relevant indicators on days 7 and 28 were observed in each group. Left ventricular function was determined by echocardiography. The structure and morphology of mitochondria, and the number of autophagic vesicles, were observed by transmission electron microscopy. The mRNA and protein expression levels of LC3, FUNDC1, Beclin-1, and BNIP3 were examined in the tissue of the MI marginal area.ResultsCompared with the MI model group, YQHXG showed obvious improvements in cardiac functions. Observing the microscopic morphology of the heart tissue, myocardial tissue damage attenuated, autophagic signs of autophagosomes and autolysosomes reduced, vacuolization in mitochondria mitigated, and mitochondria arranged in order. YQHXG could reduce the degree of tissue lesion after MI and regulate the expression of autophagy-related molecules at different stages. On Day 7, YQHXG significantly downregulated the expression of Fundc1, Becn1, Bnip3 mRNA and reduced the levels of FUNDC1, Beclin-1, BNIP3, and LC3 B proteins expression (all P < .001). On Day 28, YQHXG could upregulate the expression of Becn1, Fundc1 and Bnip3 mRNA and increased the levels of the corresponding proteins expression (all P < .001). Besides, it also increased LC3 B protein expression level (P = .0344).ConclusionYQHXG regulated the expression of mitochondrial autophagy-related factors in myocardial tissue and mitochondrial autophagic activity at different stages to protect the heart following MI. 相似文献

《中医科学杂志(英文)》2020,7(4):375-385
ObjectiveTo determine the effect of gut microbiota on a rat model of post-traumatic stress disorder (PTSD) and explore the correlation of gut microbiota with behavior and neurotransmitters.MethodsWe established a single prolonged stress (SPS) model to examine the pathogenesis of PTSD on rat behavior, gut microbiota, and neurotransmitter levels. Rats were separated into control and model groups, and neurotransmitter levels were measured using enzyme linked immunosorbent assay. Then, 16 S rRNA sequencing was used to compare the gut microbiota between the control and model groups.ResultsCompared with those in the control group, freezing time significantly increased, while number of standing upright, crossing frequency, time spent in the central arena, and total distance traveled were significantly reduced in the model group after exposure to SPS (all P < .05). Meanwhile, serotonin, or 5-hydroxytryptamine, levels in the brain in the model group were significantly lower than those the control group (P = .0332). In addition, changes were observed in the gut microbiota diversity and relative abundances of bacterial phyla, orders, families, and genera in the model group. Especially, changes in Firmicutes, Bacteroidetes, Cyanobacteria, and Proteobacteria levels were most pronounced after SPS exposure. Correlation analysis showed that the strongest positive correlation was found between Bacteroidaceae and 5-HT (P = .0009). Moreover, RF32 abundance was the most negatively related to 5-HT (P = .0009), crossing frequency (P = .0007), and total distance (P = .0003).ConclusionOur results suggest that SPS model rats showed differences in behavior, neurotransmitter levels, and gut microbiota with control rats. Moreover, Firmicutes, Bacteroidetes, Cyanobacteria, and Proteobacteria were most relevant to the exhibited fear-like and anxiety-like behaviors and significant serotonin content reduction in SPS model rats. 相似文献

ObjectiveTo investigate the anti-angiogenic effect of tea polyphenols (TPS) on breast cancer and normal tissues in a mouse model.MethodsBreast cancer was successfully implanted into 48 BALB/c mice, which were then randomly divided into a TP oral gavage group, a TP local injection group, a ginsenoside Rg3 group, and a model control group according to a random number table. The tumor inhibitory rates of each group were calculated, while microvessel density (MVD) and the expression of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and tissue inhibitor of metalloproteinase (TIMP-2) were detected by immunohistochemistry.ResultsTPs could inhibit the growth of breast cancer xenografts in the mouse model. The tumor inhibition rates of the TP oral gavage and TP local injection groups were 37.43% and 40.94%, respectively. Compared with the model control group, MVD and VEGF and bFGF expression was downregulated (all P < .05), whereas TIMP-2 expression was elevated in the TP oral gavage and TP local injection groups (P = .015 and P = .032). TPs showed no significant effect on MVD and VEGF and TIMP-2 expression in the heart, brain, and kidney of the mouse model.ConclusionTPs can restrict the growth of breast cancer by specifically inhibiting the angiogenesis of breast tumor tissue while having little effect on the normal tissue of important organs including the heart, brain, and kidney. 相似文献

ObjectiveTo uncover the underlying mechanism of Hewei Jiangni granule (HWJNG) on non-erosive reflux disease (NERD) treatment by examining histological changes, gastrointestinal neurochemicals release and visceral hypersensitivity-related receptor expression in NERD model rats.MethodsA NERD rat model was established via a combination of basal sensitization and acid perfusion. HWJNG treatments at different doses were then administered. Pathological changes to tissues, mast cell (MC) activation, serum levels of esophageal visceral hypersensitivity-related neurochemicals, and transient receptor potential (TRP) receptor mRNA and protein levels were investigated.ResultsCompared with the control group, the expression of tryptase in MCs, the changes of intercellular space, and the serum levels of substance P (SP), calcitonin gene-related peptides (CGRP) and proteinase-activated receptor 2 (PAR2) increased in the model group (all P < .05). The expression of TRP vanilloid 1 (Trpv1) mRNA decreased in esophagus and dorsal root ganglia (DRG) of the model group (P = .030 & P = .013), and the expression of TRP melastatin channel subfamily member 8 (Trpm8) mRNA decreased in the esophagus of model group (P < .01). The level of esophageal TRPV1 protein increased in the model group (P < .01) and the level of TRPM8 protein decreased in esophagus and DRG of the model group (both P < .05). Compared with the model group, the serum levels of SP, CGRP, and PAR2 in the medium-dose HWJNG group showed significant decreases (all P < .05). The expression of Trpv1 mRNA in esophagus and DRG of the HWJNG groups and the Omeprazole group remarkably decreased (all P < .05), as was the expression of Trpm8 mRNA in esophagus of the HWJNG groups (all P < .05).ConclusionHWJNG alleviated visceral hypersensitivity in NERD model rats by regulating TRP-mediated signaling. Our results indicate that HWJNG has potential as a therapeutic agent for NERD. 相似文献

ObjectiveThe Flower of Lobed Kudzuvine [Pueraria lobata (Willd.)Ohwi; Gehua in Chinese; GH] and Japanese Raisin Tree Seed (Hovenia dulcis Thunnb.; Zhijuzi in Chinese; ZJZ) are herbs that have been used in China for the treatment of alcohol intoxication and liver diseases. We aimed to evaluate the hepatoprotective potential of a combination of these in mice with acute alcohol-induced liver injury, and to elucidate the mechanisms involved.MethodsMale ICR mice were randomly allocated to six groups: a control group, an alcohol-administered group, and groups that were administered alcohol and one of silibinin, the GH, the ZJZ or a GH-ZJZ combination (at a ratio of 2:1). Animals were orally administered 56% alcohol (Er Guo-tou white spirit, 0.12 mL/10 g/d) for 10 days and at the end of this period, hepatic biochemical indicators, antioxidant parameters, alcohol metabolic enzymes, and histopathologic changes were evaluated. Moreover, the expression of the signaling molecules KEAP1, NRF2, and AQP9 were measured by qRT-PCR and western blotting.ResultsCompared with the model group, GH-ZJZ (2:1) had lower serum ALT (12.15 ± 0.39, P = .003), AST (104.07 ± 1.03, P = .001), and ALP (148.09 ± 2.55, P = .010) activities, and lower TC (1.97 ± 0.05, P = .001) and TG (1.54 ± 0.07, P = .002) concentrations. GH-ZJZ (2:1) also significantly increased the hepatic activities of SOD and GSH (4.24 ± 0.25 and 1.57 ± 0.06, respectively; both P < .01), reduced the ROS and MDA concentrations (97.50 ± 3.00 and 2.39 ± 0.19, respectively; both P < .01), and upregulated Nrf2 expression (P < .01). GH-ZJZ (2:1) significantly reduced the expression of KEAP1 and AQP9 in the liver, compared with alcohol-administered mice (P < .01). Importantly, the GH-ZJZ combination caused a more marked improvement in acute liver injury than GH or ZJZ alone.ConclusionWe have demonstrated protective effects of GH-ZJZ (2:1) against acute alcohol-induced hepatic injury, and shown that these effects may be associated with improvements in lipid and alcohol metabolism, antioxidant capacity, and lipid peroxidation. 相似文献

ObjectiveATP-binding cassette transporter A1 (ABCA1) is an integral membrane protein that plays a key role in cellular lipid metabolism, preventing the accumulation of lipids that contribute to the initiation and progression of atherosclerosis. Tiaozhi Tongmai Granules are a Chinese herbal compound that is capable of treating atherosclerosis. This study was designed to explore the potential pharmacological mechanism by which Tiaozhi Tongmai Granules protect against atherosclerosis.MethodsForty-nine male New Zealand rabbits were randomly divided into seven groups: normal control group, normal diet; model groups 1 and 2: balloon injury and high-fat diet for 6 or 12 weeks; statin groups 1 and 2: balloon injury and high-fat diet plus atorvastatin for 6 or 12 weeks; and Chinese herb groups 1 and 2: balloon injury and high-fat diet plus Tiaozhi Tongmai Granules for 6 or12 weeks. The granules were administered at a dose of 1.14 g/kg/d, with atorvastatin (1.14 mg/kg/d) serving as positive control. Serum lipid profiles and liver function indices were measured. Atherogenesis was viewed after H&E staining and quantified by thickened intimal area percentage and maximal intimal thickness percentage. The ABCA1 protein expression in atherosclerotic plaque macrophages of the common carotid arteries (CCA), thoracic aortae (TA), and liver tissues were observed by immunohistochemical staining and evaluated using mean optical density (OD) value in macrophages and ABCA1-positive hepatocyte number.ResultsCompared with model group 1 at week 6, Chinese herb group 1 and statin group 1 displayed significant reductions in total cholesterol (TC) (P = 0.027, 0.012) and low-density lipoprotein cholesterol (LDL-C) (P = 0.039, 0.028) levels, as well as marked increases in ABCA1-positive hepatocyte numbers (P all <0.001), and only statin group 1 displayed a markedly reduced maximal intimal thickness percentage in the CCA (P = 0.018). Compared with model group 2 at week 12, Chinese herb group 2 and statin group 2 all presented significant reductions in TC (P = 0.011, 0.003), LDL-C (P = 0.017, 0.010) and thickened intimal area percentage in the CCA (P = 0.001, 0.022), as well as prominent increases in the ABCA1 OD value of both the CCA (P = 0.001, 0.039) and TA (P = 0.001, 0.025) and positive hepatocyte number (P all <0.001). Chinese herb group 2 had a markedly reduced maximal intimal thickness percentage compared with model group 2 (P = 0.006) and a higher positive hepatocytes number than statin group 2 (P = 0.001).ConclusionsTiaozhi Tongmai Granules appear to have an anti-atherogenic effect that is most likely mediated by simultaneously upregulating the protein expression of ABCA1 in rabbit atherosclerotic plaque macrophages and in the liver. 相似文献

ObjectiveProlonged use of nonsteroidal anti-inflammatory drugs is associated with severe side effects and toxicity. Therefore, we studied the anti-inflammatory role of Calcarea carbonica which had minimal toxicity at the low doses.MethodsTHP-1 human mononuclear cells were treated with C. carbonica to evaluate the 50% cytotoxicity concentration (CC50) and 50% effective concentration (EC50). Cell survival was evaluated in lipopolysaccharide-stimulated C. carbonica-treated cells. Nitric oxide (NO) and tumor necrosis factor-α (TNF-α) were measured to evaluate the anti-inflammatory activity of C. carbonica. Cyclooxygenase-2 (COX-2) protein expression was determined by Western blotting analysis, and the interaction of C. carbonica with the COX-2 protein was evaluated using molecular docking simulation.ResultsThe CC50 and EC50 of C. carbonica were found to be 43.26 and 11.99 µg/mL, respectively. The cell survival assay showed a 1.192-fold (P = 0.0129), 1.443-fold (P = 0.0009) and 1.605-fold (P = 0.0004) increase in cell survival at 24, 48 and 72 h after initiating C. carbonica treatment, respectively. C. carbonica-treated cells showed a reduction in NO levels by 2.355 folds (P = 0.0001), 2.181 folds (P = 0.0001) and 2.071 folds (P = 0.0001) at 24, 48 and 72 h, respectively. The treated cells also showed a reduction in TNF-α levels by 1.395 folds (P = 0.0013), 1.541 folds (P = 0.0005) and 1.550 folds (P = 0.0005) at 24, 48 and 72 h, respectively. In addition, a 1.193-fold reduction (P = 0.0126) in COX-2 protein expression was found in C. carbonica-treated cells. The molecular docking showed interaction of C. carbonica with the phenylalanine 367 residue present in active site of Cox-2.ConclusionC. carbonica exhibited anti-inflammatory properties in lipopolysaccharide-stimulated cells by significantly reducing NO production and TNF-α level through downregulation of the COX-2 protein. This effect is probably mediated through interaction of C. carbonica with the phenylalanine 367 residue present in active site of Cox-2. 相似文献

ObjectiveTo explore the inhibitory effect of Tangshenping (TSP) on pyroptosis in a streptozotocin-induced diabetic nephropathy (DN) rat model.MethodsDN was established in Sprague–Dawley rats. Rats were randomly divided into DN (model group), irbesartan, and TSP low-, medium-, and high-dose groups, besides the control group. The 24 h albuminuria content, and serum content of TC, TGs, Scr, IL-1β, UREA, LDLs, and IL-18 were assessed. Hematoxylin & eosin and Mallory staining were performed to examine pathological changes in the kidney. The mRNA and protein expression of NLRP3, caspase 1, and GSDMD in the kidney were also examined.ResultsThe 24 h albuminuria content was obviously lower in the treatment groups compared to the model group (all P < .01). Levels of TC, TGs, Scr, UREA, LDLs, and IL-18 after drug interventions were obviously lower compared to the model group (all P < .05). The serum content of IL-1β in the TSP medium- and high-dose groups were much lower compared to the model group (P = .013 and P = .001, respectively). Through immunohistochemistry and western blotting, we observed that the protein expressions of NLRP3, caspase-1, GSDMD, IL-1β, and IL-18 were lower after drug interventions compared to the model group (all P < .05). Using qPCR, we observed that the mRNA expressions of caspase-1, IL-1β, IL-18, and GSDMD after drug interventions were significantly lower compared to the model group (all P < .05). The mRNA expressions of NLRP3 in the TSP medium- and high-dose groups were both lower compared to the model group (all P < .05).ConclusionTSP downregulated mRNA and protein expressions of NLRP3, caspase-1, and GSDMD. Our findings demonstrate that the beneficial effects of TSP on renal function are at least partly mediated by the inhibition of micro-inflammation and modulation of the expression of pyroptosis-related factors. 相似文献
