[PMID: 38423407 DOI: 10.1016/j.jep.2024.117987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 02/23/2024] [Accepted: 02/25/2024] [Indexed: 03/02/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paeoniae Radix Rubra (PRR) is the dried root of Paeonia lactiflora Pall, which has been widely used to anti-thrombotic, lipid-lowering, anti-spasmodic, antioxidant, antibacterial, hepatoprotective, and anti-tumor in Chinese clinical practice. Recent research has demonstrated that PRR plays a significant anti-tumor role in animal models of tumor-bearing. AIM OF THE STUDY There has not been the evaluation of the anti-tumor effects of PRR. This study conducts a meta-analysis to assess the anti-tumor efficacy of PRR on animal models, providing scientific evidence for clinical application of PRR in the adjuvant therapy of tumors. MATERIALS AND METHODS English databases (PubMed, The Cochrane Library, Embase, and Web of Science) and Chinese databases (CNKI, WanFang, SinoMed, CTSJ-VIP) were used to search all pertinent animal studies investigating the anti-tumor effects of PRR and its extracts. The quality of the included studies was evaluated using the SYRCLE animal experiment risk assessment tool, and statistical analysis was carried out using Revman 5.3 software. Egger's test and funnel plots were used to assess potential publication bias in the studies. RESULTS The initial search produced a total of 3905 potentially pertinent studies, and 24 studies met the inclusion criteria. These studies included animal tumor models of hepatocellular carcinoma, lung cancer, sarcoma, bladder cancer, leukemia, colon cancer, glioblastoma, and pancreatic cancer. The meta-analysis findings demonstrated that both PRR and its extracts significantly inhibited tumor growth in animals. Compared with the control group, PRR substantively inhibited tumor volume (SMD, -3.09; 95% CI, [-4.05, -2.13]; P < 0.0001), reduced tumor weight (SMD, -1.08; 95% CI, [-1.37, -0.78]; P < 0.0001), decreased tumor number (SMD, -2.16; 95% CI, [-3.45, -0.86]; P = 0.001), and prolonged the survival duration time (SMD, 0.97; 95% CI, [0.23, 1.71]; P = 0.01) on the experimental animals. CONCLUSIONS PRR displayed a potential therapeutic efficacy on eight tumors in animal models including hepatocellular carcinoma, lung cancer, sarcoma, bladder cancer, leukemia, colon cancer, glioblastoma, and pancreatic cancer. However, the quality and quantity of included studies may affect the accuracy of positive results. In the future, more high-quality randomized controlled animal experiments are need for meta-analysis.

Abstract
Tumors have a huge impact on human life and are now the main cause of disease-related deaths. The main means of treatment are surgery and radiotherapy, but they are more damaging to the organism and have a poor postoperative prognosis. Therefore, we urgently need safe and effective drugs to treat tumors. In recent years, Chinese herbal medicines have been widely used in tumor therapy as complementary and alternative therapies. Medicinal and edible herbs are popular and have become a hot topic of research, which not only have excellent pharmacological effects and activities, but also have almost no side effects. Therefore, as a typical medicine and food homology, some components of Paeoniae Radix Alba (PRA, called Baishao in China) have been shown to have good efficacy and safety against cancer. Numerous studies have also shown that Paeoniae Radix Alba and its active ingredients treat cancer through various pathways and are also one of the important components of many antitumor herbal compound formulas. In this paper, we reviewed the literature on the intervention of Paeoniae Radix Alba in tumors and its mechanism of action in recent years and found that there is a large amount of literature on its effect on total glucosides of paeony (TGP) and paeoniflorin (PF), as well as an in-depth discussion of the mechanism of action of Paeoniae Radix Alba and its main constituents, with a view to promote the clinical development and application of Paeoniae Radix Alba in the field of antitumor management.

Mechanism of Xiaojianzhong decoction in alleviating aspirin-induced gastric mucosal injury revealed by transcriptomics and metabolomics. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116910. [PMID: 37453623 DOI: 10.1016/j.jep.2023.116910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Revised: 07/10/2023] [Accepted: 07/11/2023] [Indexed: 07/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aspirin, as a first-line drug for the treatment of cardiovascular diseases, currently has high clinical usage. However, reports of aspirin-induced gastric mucosal injury are increasing. Xiaojianzhong decoction (XJZD), a classic traditional Chinese medicine formula, has been shown to alleviate gastric mucosal injury, although its potential mechanism of action requires further study. AIM OF THE STUDY This study aimed to explore the effect and mechanism of XJZD in preventing aspirin-induced gastric mucosal injury. MATERIALS AND METHODS Aspirin was used to induce damage in the morning, while XJZD was applied as an intervention in the afternoon. The compounds in the XJZD were analyzed by means of both high-performance liquid chromatography and ultra-performance liquid chromatography-tandem mass spectrometry. The overall condition of the aspirin-related gastric mucosal injury was evaluated. The expressions of inflammatory factors and tight-junction-related proteins and apoptosis were observed via immunohistochemistry and immunofluorescence. The expression levels of the apoptosis-related proteins were detected using Western blot. Transcriptomics was used to perform the integrative analysis of gastric tissues, which was then validated. Molecular dynamics was used to explore the interaction of key compounds within the XJZD with relevant targets. Finally, non-targeted metabolomics was used to observe any metabolic changes and construct a network between the differentially expressed genes and the differential metabolites to elucidate their potential relationship. RESULTS XJZD can alleviate inflammation response, maintain the gastric mucosal barrier's integrity, reduce apoptosis and necroptosis levels, and promote the proliferation and repair of gastric mucosal tissues. Its mechanism of action may be related to the regulation of TNF-α signaling. Furthermore, molecular docking showed that the cinnamaldehyde within XJZD played an important role in its effects. In addition, XJZD can correct metabolic disorders, mainly regulating amino acid metabolism pathways. Moreover, six differential genes (Cyp1a2, Cyp1a1, Pla2g4c, etc.) were determined to alleviate both gastric mucosal injury and inflammation by regulating arachidonic acid metabolism, Tryptophan metabolism, etc. CONCLUSIONS: This study is the first to report that XJZD can inhibit necroptosis and gastric mucosal injury induced by aspirin, thereby revealing the complex mechanism of XJZD in relation to alleviating gastric mucosal injury from multiple levels and perspectives.

Liu F, Nong X, Qu W, Li X. Pharmacokinetics and tissue distribution of 12 major active components in normal and chronic gastritis rats after oral administration of Weikangling capsules. JOURNAL OF ETHNOPHARMACOLOGY 2023:116722. [PMID: 37271330 DOI: 10.1016/j.jep.2023.116722] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Revised: 05/28/2023] [Accepted: 05/31/2023] [Indexed: 06/06/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Weikangling Capsules (WKLCs) have been used in the clinic for the treatment of gastrointestinal disorders for more than 30 years. However, the pharmacokinetic characteristics and tissue distribution of its major bioactive components in rats under different physiological and pathological conditions are unclear. AIM OF THE STUDY In this study, we aimed to clarify the differences in pharmacokinetic parameters and tissue distribution of the major active components in WKLCs under physiological and pathological states. MATERIALS AND METHOD Normal and ethanol-induced chronic gastritis rats received 2.16 g/kg WKLCs by gavage, and urine, feces, plasma, and tissue (heart, liver, spleen, lung, kidney, stomach, and small intestine) samples were obtained. The active components in urine, feces and plasma were detected by ultra-high-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UHPLC-Q-TOF-MS/MS). A rapid and sensitive analytical method, ultra-high-performance liquid chromatography coupled with triple-quadrupole linear ion-trap tandem mass spectrometry (UHPLC-QTRAP-MS/MS), was established and validated to clarify and compare the pharmacokinetics and tissue distribution of the major active components in normal and chronic gastritis rats. RESULTS A total of 36 chemical components in the feces, urine, and plasma of chronic gastritis rats were identified by UHPLC-Q-TOF-MS/MS. Among them, 20 were the prototype components of WKLCs, and 16 were metabolites. The pharmacokinetic characteristics and tissue distribution of 12 prototype components were successfully analyzed by UHPLC-QTRAP-MS/MS. The pharmacokinetic results showed that the Cmax, AUC0-t, and AUC0-∞ of paeoniflorin, glycyrrhizic acid, and glycyrrhetinic acid were distinctly higher than those of the other components in normal and chronic gastritis rats. Compared to normal rats, the Cmax, AUC0-t, and AUC0-∞ of albiflorin, liquiritin apioside, liquiritin, isoliquiritin, ononin, isoliquiritigenin, dactylorhin A, and glycyrrhizic acid were significantly increased in chronic gastritis rats (P < 0.05), while the Cmax, AUC0-t and AUC0-∞ of militarine and liquiritigenin had significantly lower decreases in chronic gastritis rats (P < 0.05). The results of the tissue distribution showed that the 12 components were widely distributed in the heart, liver, spleen, lung, kidney, stomach, and small intestine of rats, of which the liver, kidney, stomach, and small intestine were the main accumulative organs. Compared with normal rats, the concentrations of 12 components in the liver, kidney, stomach, and small intestine of chronic gastritis rats were widely higher than those of normal rats at the same time points. CONCLUSION The pharmacokinetic characteristics and tissue distribution of 12 active components of WKLCs were comprehensively characterized and elucidated in normal and chronic gastritis rats. These findings laid a solid foundation for revealing the pharmacodynamic material basis of WKLCs in treating gastrointestinal disorders.

Life Sci 2023; 315:121368. [PMID: 36623766 DOI: 10.1016/j.lfs.2023.121368] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 12/22/2022] [Accepted: 01/01/2023] [Indexed: 01/09/2023]
Abstract
AIMS Weikangling capsules (WKLCs) have been widely used in the treatment of chronic gastritis. Whether used alone or combined with omeprazole (OME), it shows a significant effect. However, the mechanisms haven't been established. The study aimed to explore the mechanisms of WKLCs and its combination with OME on chronic gastritis. MAIN METHODS The components of WKLCs and EA (the ethyl acetate extraction extracted from WKLCs) fraction were analyzed. Then chronic gastritis model rats were induced by 56 % ethanol and treated with OME, low dose of WKLCs (WKL), high dose of WKLCs (WKH), WKLCs combined with OME (WO), and EA fraction (EA) to evaluate the mechanisms of WKLCs, drug combination and EA fraction. KEY FINDINGS A total of 22 components of WKLCs were quantified, among them 18 were enriched in EA fraction. WKLCs alleviated the morphology and inflammation of gastric mucosa and downregulated the levels of inflammatory factors (IL-1β, TNF-α, IL-6) and epidermal growth factor (EGF) in serum by inhibiting the EGF-EGFR-ERK pathway, regulating gut microbiota composition and SCFAs contents in feces. WKLCs plus OME was better than OME. EA fraction improved digestive function by increasing pepsin activity and decreasing gastrointestinal hormones (GAS and VIP) compared with WKLCs. SIGNIFICANCE This study elucidated that the effect of WKLCs and its combination with OME in the treatment of chronic gastritis was attributed to regulating the composition of the gut microbiota and inhibiting the EGF-EGFR-ERK pathway. The EA fraction is an inseparable effective substance of WKLCs. This study provides scientific evidence for clinical application.

Abstract
Weikangling capsules (WKLCs), a Chinese patent medicine consisting of 8 Chinese drugs, have been widely used in clinic to treat gastrointestinal diseases for more than 30 years. The current "Chinese Pharmacopoeia" (2020 Edition, ChP2020) uses paeoniflorin content (≥ 1.0 mg per capsule) as the standard of quality control, but it is insufficient to evaluate the overall quality of WKLCs. An efficient and economic method for quality control is urgently needed to ensure the quality consistency and clinical effects of WKLCs. Herein, a systematic and reliable method for the rapid analysis of chemical components in WKLCs was established for the first time based on ultra-performance liquid chromatography/quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS). A total of 115 components covering 7 herbs in WKLCs were preliminarily identified by comparison with standard substances or literature. To evaluate the quality of 26 batches of WKLCs, a new method of fingerprinting combined with quantitative analysis was established, and 16 common peaks were selected to establish the fingerprint similarity model (similarity>0.90). Simultaneously, the contents of albiflorin, paeoniflorin, dactylorhin A, militarine, and glycyrrhizic acid were determined to be 0.82 ± 0.22, 2.09 ± 0.24, 1.15 ± 0.40, 3.73 ± 0.76 and 0.99 ± 0.20 mg/capsule, respectively. The transfer rates and dissolution curves of the five compounds were successfully detected in WKLCs, and the average transfer rates were 67.2%, 33.0%, 68.3%, 54.7%, and 33.7%, respectively. Notably, the dissolution profiles of different manufacturers presented remarkable differences in pH 1.2 hydrochloric acid solution. This method not only qualitatively identified the chemical components of Chinese patent medicines at the microlevel but also evaluated the quality consistency between batches at the macrolevel, which provided a comprehensive reference for the quality consistency of Chinese patent medicines between batches.

Abstract
BACKGROUND/AIMS This study was conducted to investigate the inhibitory effect of irsogladine maleate (IM) on gastric ulcers induced by ethanol and hydrochloric acid (HCl). METHODS Mice were pretreated with IM for 1 hours before ulcer induction. Gastric ulcers were induced by oral administration of an ethanol/HCl mixture. To clarify the action mechanism of IM, the roles of 3'5'-cyclic adenosine monophosphate (cAMP), nitric oxide (NO), adenosine triphosphate-sensitive potassium (KATP) channels, prostaglandins and transient receptor potential cation channel subfamily V member 1 (TRPV1) were investigated, and lipid peroxidation in the stomach of IM-treated and -untreated animals was also measured. RESULTS IM significantly reduced the extent of ethanol/HCl mixture-induced gastric ulceration. It exhibited dose-related gastroprotection against the ethanol/ HCl-induced lesions, while pretreatment with glibenclamide but not N(ω)-nitro- L-arginine methyl ester, reversed this action. While pretreatment with the TRPV1 antagonist capsazepine failed to effectively block the gastroprotective effect of IM, the non-selective cyclooxygenase inhibitor indomethacin almost abolished it. IM also decreased the level of thiobarbituric acid reactive substances. CONCLUSION We concluded that IM exhibited significant gastroprotective effects in an ethanol/HCl-induced ulcer model, which appear to be mediated, at least in part, by NO, cAMP, endogenous prostaglandins, KATP channel opening, activation of TRPV1 channels, and antioxidant properties.

Total glucosides of herbaceous peony (Paeonia lactiflora Pall.) flower attenuate adenine- and ethambutol-induced hyperuricaemia in rats. JOURNAL OF ETHNOPHARMACOLOGY 2020; 261:113054. [PMID: 32534113 DOI: 10.1016/j.jep.2020.113054] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Revised: 05/19/2020] [Accepted: 05/30/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herbaceous peony (Paeonia lactiflora Pall.) flower has been used widely in dietotherapy in China and other countries. It has good ethnopharmacological value in the treatment of various metabolic diseases. However, the molecular mechanisms by which it lowers serum uric acid are unknown. The development of pharmaceutical resources is very important. Here, we sought to elucidate the mode of action of herbaceous peony in terms of reducing uric acid levels. AIM OF THE STUDY In the present research, the effects of the total glucosides of herbaceous peony flower were investigated in a rat hyperuricaemia model. Another aim of the study was to clarify the mechanism by which herbaceous peony flower (TGPF) lowers serum uric acid levels. MATERIALS AND METHODS A hyperuricaemic rat model was induced via intragastric administration of 100 mg/kg adenine and 250 mg/kg ethambutol hydrochloride (EH) for 23 d. Then TongFengShu 600 mg/kg, allopurinol 42 mg/kg, or TGPF (50 mg/kg, 100 mg/kg, or 200 mg/kg) was administered 1 h after the adenine and EH treatments. RESULTS TGPF improved weight loss and decreased serum UA, XOD, MCP-1, TNF-α, Cr, and BUN in the rats with hyperuricaemic nephropathy. TGPF downregulated renal URAT1 and GLUT9, upregulated renal OAT1, and ameliorated histopathological changes in the thymus, spleen, and kidney. CONCLUSION TGPF is promising as a therapeutic agent against hyperuricaemia. It regulates the uric acid transporters and diminished serum uric acid levels, and alleviates renal pathology associated with hyperuricaemia.

Gastroprotective Effects of Paeonia Extract Mixture HT074 against Experimental Gastric Ulcers in Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:3546258. [PMID: 30906413 PMCID: PMC6398042 DOI: 10.1155/2019/3546258] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Accepted: 02/03/2019] [Indexed: 12/26/2022]
Abstract
Background Paeonia extract mixture HT074 is a standardized multiherbal mixture comprising extracts from Inula britannica flowers and Paeonia lactiflora roots, which are used to treat digestive disorders in traditional Korean medicine. This study was focused on elucidating the underlying mechanisms of the gastroprotective effects of HT074 in different gastric ulcer models. Methods Gastric lesions were induced in rats by an HCl/EtOH solution, water immersion-restraint stress (WIRS), and indomethacin. Gastric secretions were studied in pylorus-ligated rats, while mucus secretions were assessed by measuring alcian blue-binding capacity of mucus in the rat model of HCl/EtOH-induced gastric ulcer. Additionally, the involvement of nitric oxide (NO) and sulfhydryl compounds in HT074-mediated mucosal protection was elucidated using their inhibitors, i.e., NG-nitro- L-arginine methyl ester hydrochloride (L-NAME) and N-ethylmaleimide (NEM), respectively. Furthermore, the effects on indomethacin-induced cell death and prostaglandin E2 (PGE2) levels were assessed in AGS cells. Results Oral administration of HT074 significantly decreased gastric lesions induced by HCl/EtOH, WIRS, and indomethacin. Furthermore, it significantly decreased the volume, acidity, and total acidity of gastric juice in pylorus-ligated rats and increased the alcian blue-stained gastric mucus in HCl/EtOH-induced gastric ulcer in rats. Pretreatment with NEM abolished the gastroprotective effects of HT074, while L-NAME did not. In AGS cells, HT074 significantly reduced indomethacin-induced cell death and increased the PGE2 levels. Conclusions These findings suggest that HT074 has gastroprotective effects against various ulcerogens, including HCl/EtOH, immersion stress, and NSAIDs. These effects are attributed to the inhibition of gastric secretions and preservation of the gastric mucosal barrier by increased mucus production, which is partially mediated through endogenous sulfhydryl compounds and PGE2. Based on these findings, we propose that HT074 may be a promising therapeutic agent for gastritis and gastric ulcer.

Abstract
Background Radix Paeoniae Rubra (RPR), a traditional Chinese herb, has anti-inflammatory and immuno-regulatory properties. This study explored the effects of RPR on stimulation of osteoclast differentiation in RAW264.7 cells and peripheral blood mononuclear cells (PBMC)s. Methods The mature osteoclasts were measured by bone resorption assays and TRAP staining. JNK, ERK, p38 and NF-κB inhibitors were used applied in order to verify their contribution in RPR-induced osteoclast differentiation. The NF-κB and MAPK pathways were evaluated by western blotting, RT-PCR and luciferase assay. Results RPR induced osteoclast differentiation in a dose-dependent manner and induced the resorption activity of osteoclasts differentiation of RAW264.7 cells and PBMCs. Western blotting showed that RPR treatment induced phosphorylation of JNK, ERK, and p38 in RAW 264.7 cells. Treatment of JNK, ERK, and p38 MAP kinase inhibitors verified the contribution of JNK, ERK and p38. RPR treatment induced c-Fos and NFATc1 protein expression; NF-κB inhibitor treatment and luciferase assay verified the contribution of the NF-κB pathway. Conclusions This study demonstrated the interesting effect, in which RPR stimulated osteoclast differentiation in murine RAW264.7 cells and human monocytes.

Abstract
The newly synthesized, 3,4,5-Trihydroxy-N 0-[(2-methyl-1H-indol-3-yl)-methylidene] benzohydrazide (TIBH), is an indole and gallic acid derivative. The aim of this research investigation was to evaluate the acute toxicity and the ulcer prevention potential of TIBH in HCl/Ethanol-induced gastric ulcer rat model. Six groups of rats were orally received 5ml/kg of vehicle (1 % Carboxy methyl cellulose) for the normal and ulcer control groups each, Omeprazole (20mg/kg) for positive control, 50 mg/kg, 100 mg/kg and 200 mg/kg of TIBH for experimental groups, respectively. After one hour, instead of rats in the normal group which received 5ml/kg of 1% CMC, other groups received 5ml/kg of HCl/Ethanol. All rats were sacrificed after one additional hour. Gastric juice, gastric mucosa, morphologies of gastric ulcers and protein expressions of both control and treatment groups were evaluated. TIBH showed a ulcer prevention potential by increase of the mucus secretion, decrease of the gastric acidity, up-regulation of HSP70 protein, down-regulation of Bax protein, decrease of the lipid peroxidation and the increase of the Superoxide dismutase (SOD) activity in gastric tissue homogenate. Acute toxicity assay exposed valuable information on the safety of this compound. TIBH had a dose dependent ulcer prevention potential against HCl/Ethanol-triggered gastric ulcer.

Abstract
Paeonia lactiflora and P. obovata are perennial herbs, each root of which has been consumed as a major oriental medicine, Paeoniae Radix and a famous folk medicine, Mountain Paeony Root, respectively. Although morphological studies have been performed comparing these two plants, there is insufficient scientific evidence that characterizes the differences in their chemical profiles and biological activities. Hence, the present study was undertaken to compare these two medicinal foods using a high-performance liquid chromatography-diode-array detector (HPLC-DAD) analysis and a gastric ulcer model in mice. HPLC analysis employed to assess the nine components revealed that P. lactiflora exhibited higher contents of phenolic compounds than P. obovata. Although a monoterpene glycoside, 6'-O-acetylpaeoniflorin was identified in P. obovata, it was not detected in P. lactiflora. Multivariate statistical analysis for HPLC data revealed that the orthogonal projections to latent structure-discriminant analysis is more appropriate than principal component analysis for differentiating the two groups. Moreover, the 50% methanol P. lactiflora extract (PL) was more effective against experimental gastric ulcer than P. obovata extract (PO) in the HCl/ethanol-induced ulcer model. In addition, PL displayed higher 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and lower nitric oxide production in a murine macrophage cell line, RAW 264.7, than PO. The DPPH radical scavenging activity of PL was as high as that of the positive control, butylated hydroxytoluene, at a concentration of 25 μg/mL.

Abstract
Paeoniflorin (PF) extracted from the root of Paeonia lactiflora pall, displays anti-inflammation properties in several animal models. Adhesion molecules are important for the recruitment of leucocyte to the vessel wall and involved in the pathogenesis of various autoimmune and inflammatory diseases. Herein, we investigate the effects of PF on adhesion molecule expression in a mouse model of cutaneous Arthus reaction and cultured human dermal microvascular endothelial cells (HDMECs). We showed that PF significantly ameliorated the immune complex (IC) induced vascular damage, leucocyte infiltrates and adhesion molecules expression. Furthermore, PF markedly blocked tumor necrosis factor-α (TNF-α)-induced E-selectin and intercellular adhesion molecule-1 (ICAM-1) expression in HDMECs at both mRNA and protein levels. PF also suppressed TNF-α-induced adhesion of polymorphonuclear leucocytes (PMNs) to HDMECs. Finally, western blot data revealed that PF can inhibit the phosphorylation of p38, JNK in TNF-α-treated HDMECs. These data suggest that PF, as an anti-inflammatory agent, can downregulate adhesion molecules expression. PF may be a candidate medicine for the treatment of IC-induced inflammatory response.

A valid approach in refractory glossodynia: a single-institution 5-year experience treating with Japanese traditional herbal (kampo) medicine. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:354872. [PMID: 24223055 PMCID: PMC3816042 DOI: 10.1155/2013/354872] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/01/2013] [Revised: 07/19/2013] [Accepted: 09/15/2013] [Indexed: 12/19/2022]
Abstract
Glossodynia is often refractory to conventional medicine, and there is only limited evidence to guide clinicians in its management. Patients with refractory glossodynia are often introduced to Japanese traditional herbal (Kampo) medicine experts under such circumstances because Kampo medicine has become known in Japan to be effective in treating a wide variety of symptoms refractory to conventional medicine. Herein, we report our single-institution 5-year experience treating patients with Kampo medicine for primary glossodynia that was refractory to conventional medicine. We found that 69.2% of patients reported a beneficial effect of Kampo medicine on glossodynia, and the average onset of improvement was 8.0 ± 7.7 weeks after starting Kampo treatment. The top two frequently used Kampo medicines for glossodynia were seinetsuhokito and mibakuekkito among high responders who showed a decrease of severity by 50% or more. The top four most overlapped herbs among effective Kampo medicines for glossodynia were Glycyrrhiza Root, Ginseng Root, Hoelen, and Atractylodes (lancea) Rhizome, which compose an essential Kampo prescription called shikunshito. Although more research is required to further clarify the effectiveness of Kampo medicine, it has valid efficacy even in cases of glossodynia that remain incurable by conventional treatments.

Clin Res Hepatol Gastroenterol 2013; 37:e3-15. [PMID: 22516481 DOI: 10.1016/j.clinre.2012.03.004] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2012] [Revised: 02/20/2012] [Accepted: 03/02/2012] [Indexed: 02/04/2023]
Abstract
AIMS Propofol has demonstrated protective effects against digestive injury. Toll-like receptor-4 (TLR4) is involved in gastric mucosal injury. However, it has not yet been clarified whether propofol protects gastric mucosa from ethanol-induced injury and whether the mechanism involved is related to TLR4 activation. Therefore, this prospective study was carried out to address the issue. METHODS Gastric mucosal injury was induced in mice by intragastric administration of ethanol. Propofol was given intraperitoneally 30 min before ethanol intragastric administration and, 1h later, gastric specimens were studied using hematoxylin--eosin staining, quantitative real-time RT-PCR, immunohistochemical staining and Western blot assays; serum specimens were studied using ELISA kits. RESULTS Propofol at 25mg/kg significantly attenuated ethanol-induced gastric mucosal injury. In addition, propofol pretreatment significantly inhibited the upregulated expression of high-mobility group box-1 (HMGB1) protein, TLR4 and its downstream signaling molecules--myeloid differentiation factor 88 (MyD88) and nuclear factor kappa-B (NF-κB)--in gastric mucosa, while suppressing the increased release of tumor neurosis factor-α (TNF-α) and interleukin-1β (IL-1β) in serum. Furthermore, upregulation of the Bax/Bcl-2 ratio in gastric mucosa was clearly depressed by propofol. CONCLUSION Propofol can inhibit HMGB1 expression and TLR4/MyD88/NF-κB-mediated inflammatory responses, and hamper apoptosis, which may contribute to its protective action against ethanol-induced gastric mucosal injury.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chronic gastritis is a very common disease of the digestive tract. Although herbal preparation Chaihu-Shugan-San (CSS) has been widely used as an alternative treatment for chronic gastritis in East Asia, its effectiveness is not verified. The purpose of this meta-analysis is to evaluate the effectiveness of CSS in treating various types of chronic gastritis. MATERIALS AND METHODS Retrospective review of pertinent literature via Embase, China National Knowledge Infrastructure database, Wanfang Data, Vip Information and the Cochrane Library search using the keywords "Chaihushugan" or "Chaihu Shugan" or "Chai Hu Shu Gan" or "Chaihu Shu Gan". Twenty-one trials were identified including 2572 patients (1384 in CSS group and 1188 in chemotherapy group). Each trial was independently reviewed by two assessors. RESULTS The risk ratios of bile reflux gastritis, chronic superficial gastritis, chronic atrophic gastritis, and chronic erosive gastritis in the CSS-treated and chemotherapy groups were 1.30, 1.20, 1.24, and 1.48, respectively. CSS had more therapeutic effect in various types of chronic gastritis patients for improving clinical response compared with the chemotherapy group. Of the 21 trials administrating CSS to patients, no adverse event was reported. CONCLUSIONS CSS was more effective compared to chemotherapy in the treatment of chronic gastritis and no serious side-effects were identified. However, the evidence is insufficient because of the low methodological quality of the included trials. More full-scale, randomized, double-blind, placebo-controlled clinical trials are recommended to further evaluate the therapeutic benefit of CSS.

Abstract
BACKGROUND H. pylori infection significantly attenuated the expression of HSP70 in gastric mucosal cells. However, the role of HSP70 cancellation in H. pylori-associated cell damages is largely unclear. METHODS Small interfering RNA (siRNA) was used to down-regulate HSP70 in gastric epithelial cell lines AGS. The transfected cells were then incubated with H. pylori and the functions of HSP70 suppression were observed by viability assay, cell cycle analyses and TUNEL assay. HSP70 target apoptotic proteins were further identified by Western blot. RESULTS The inhibition of HSP70 has further increased the effect of growth arrest and apoptosis activation triggered by H. pylori in gastric epithelial cells. The anti-proliferation function of HSP70 depletion was at least by up-regulating p21 and cell cycle modulation with S-phase accumulation. An increase of apoptosis-inducing factor (AIF) and cytosolic cytochrome C contributes to the activation of apoptosis following down-regulation of intracellular HSP70. Extracellular HSP70 increased cellular resistance to apoptosis by suppression the release of AIF and cytochrome c from mitochondria, as well as inhibition of p21 expression. CONCLUSIONS The inhibition of HSP70 aggravated gastric cellular damages induced by H. pylori. Induction of HSP70 could be a potential therapeutic target for protection gastric mucosa from H. pylori-associated injury.

Abstract
OBJECTIVE The present study aims to explore the effects of paeoniflorin (PF), a monoterpene glycoside isolated from the roots of Paeonia lactiflora Pallas, on acute lung injury (ALI) and the possible mechanisms. MATERIALS AND METHOD ALI was induced in mice by an intratracheal instillation of lipopolysaccharide (LPS, 1 mg/kg), and PF was injected intraperitoneally 30 min prior to LPS administration. After 24 h, lung water content, histology, microvascular permeability and proinflammatory cytokines in the bronchoaveolar lavage fluid were evaluated. RESULTS It was shown that PF (50, 100 mg/kg) could alleviate LPS-induced ALI, evidenced by reduced pulmonary edema, improved histological changes, and attenuated inflammatory cell accumulation in the interstitium and alveolar space as well as microvascular permeability. It also markedly down-regulated the expressions of proinflammatory cytokines interleukin (IL)-1β and tumor necrosis factor (TNF)-α at both transcription and protein levels. Additionally, PF inhibited the phosphorylations of p38 MAP kinase (p38) and c-Jun NH2-terminal kinase (JNK) but not extracellular signal-regulated kinase (ERK), and prevented the activation of nuclear factor-kappa B (NF-κB) in the lung tissues. CONCLUSION The findings suggest that PF is able to alleviate ALI, and the underlying mechanisms are probably attributed to decreasing the production of proinflammatory cytokines through down-regulation of the activation of p38, JNK and NF-κB pathways in lung tissues.
