Quantification of Paeoniflorin by Fully Validated LC-MS/MS Method: Its Application to Pharmacokinetic Interaction between Paeoniflorin and Verapamil. Molecules 2022; 27:molecules27238337. [PMID: 36500431 PMCID: PMC9737983 DOI: 10.3390/molecules27238337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 11/23/2022] [Accepted: 11/26/2022] [Indexed: 12/03/2022] Open
Abstract
A rapid, sensitive, and specific LC-MS/MS method was developed and fully validated for the detection of paeoniflorin only in rat plasma, and applied to pharmacokinetic studies, including intravenous, multi-dose oral and combined administrations with verapamil. In this study, tolbutamide was used as the internal standard, and the protein precipitation extraction method, using acetonitrile as the extraction agent, was used for the sample preparation. Subsequently, the supernatant samples were analyzed on a Phenomenex Gemini® NX-C18 column with a flow rate of 1.0 mL/min in a gradient elution procedure. In the extracted rat plasma, the method exhibited high sensitivity (LLOQ of 1.0 ng/mL) upon selecting ammonium adduct ions ([M+NH4]+) as the precursor ions and good linearity over the concentration range of 1.0−2000 ng/mL, with correlation coefficients >0.99. The intra- and inter-batch accuracy RE% values were within ±8.2%, and the precision RSD% values were ≤8.1% and ≤10.0%, respectively. The results show that the method can be successfully applied to quantitate paeoniflorin in biological samples. Additionally, paeoniflorin is subsequently confirmed to be the substrate of the P-gp transporter in vivo and in vitro for the first time, which would be necessary and beneficial to investigate the clinical safety and efficacy of PF with other drugs in the treatment of rheumatoid arthritis.

Abstract
Background: This study aimed to investigate the molecular mechanism of Radix Paeoniae Alba (white peony, WP) in treating immune inflammatory diseases of rheumatoid arthritis (RA) and tumor necrosis factor-alpha (TNF-α) inhibitors (TNFis) by using network pharmacology and molecular docking. Methods: In this study, the ingredient of WP and the potential inflammatory targets of RA were obtained from the Traditional Chinese Medicine Systematic Pharmacology Database, GeneCard, and OMIM databases, respectively. The establishment of the RA-WP-potential inflammatory target gene interaction network was accomplished using the STRING database. Network maps of the WP-RA-potential inflammatory target gene network were constructed using Cytoscape software. Gene ontology (GO) and the biological pathway (KEGG) enrichment analyses were used to further explore the RA mechanism and therapeutic effects of WP. Molecular docking technology was used to analyze the optimal effective components from WP for docking with TNF-α. Results: Thirteen active ingredients and 71 target genes were screened from WP, and 49 of the target genes intersected with RA target inflammatory genes and were considered potential therapeutic targets. Network pharmacological analysis showed that the WP active ingredients such as mairin, DPHCD, (+)-catechin, beta-sitosterol, paeoniflorin, sitosterol, and kaempferol showed better correlation with RA inflammatory target genes such as PGR, PTGS1, PTGS2, NR3C2, TNFSF15, and CHRM2, respectively. The immune-inflammatory signaling pathways of the active ingredients for the treatment of RA are the TNF-α signaling pathway, Toll-like receptor signaling pathway, cell apoptosis, interleukin-17 signaling pathway, C-type lectin receptor signaling pathway, mitogen-associated protein kinase, etc. Molecular docking results suggested that mairin was the most appropriate natural TNFis. Conclusion: Our findings provide an essential role and basis for further immune-inflammatory studies into the molecular mechanisms of WP and TNFis development in RA.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 258:112913. [PMID: 32371143 DOI: 10.1016/j.jep.2020.112913] [Citation(s) in RCA: 83] [Impact Index Per Article: 20.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Revised: 04/19/2020] [Accepted: 04/22/2020] [Indexed: 05/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paeoniae Radix Alba (PRA, called baishao in China), the root of Paeonia lactiflora Pall., has shown a rich medicinal value for more than 2000 years. PRA is used in local medicine and traditional medicine for autoimmune diseases associated with inflammation. At present, total glucosides of paeony (TGP), the main active ingredient of PRA, has been developed into a preparation for the treatment of autoimmune diseases, as TGP exhibits the effect of regulating immunity, anti-inflammatory, and analgesic effects. AIM OF THE REVIEW TGP was developed and applied to inflammation-related autoimmune diseases in modern clinical practice. Based on its application in traditional prescriptions, this article reviews PRA's botany and phytochemistry (including its extraction process and quality control), and discusses the clinical application and pharmacological research of TGP as an anti-inflammatory drug from the perspective of ethnopharmacology. Additionally, we review modern pharmacological and molecular-target research on TGP and discuss the mechanisms of TGP in treating autoimmune diseases. Through a systematic literature review, we also highlight the clinical efficacy of TGP in the treatment of immune diseases, and provide a reference for the continued scientific development and quality control of TGP so that its wider application and clinical value can be fully realized. MATERIALS AND METHODS Literature search was conducted through the Web of Science, Baidu Scholar, ScienceDirect, PubMed, CNKI, and WanFang DATA using the keywords "Total glucosides of paeony", "Paeonia lactiflora Pall. ", "Paeonia veitchii Lynch", "Paeoniae Radix Alba or white peony", "Paeoniae Radix Rubra or red peony", "Paeoniflorin", "Albiflorin", "Autoimmune diseases", and their combinations. In addition, information was collected from relevant textbooks, reviews, and documents. RESULTS Approximately 15 compounds have been identified in TGP, of which paeoniflorin and albiflorin are the most common constituents. In recent years, studies have found that TGP and its main chemical components are effective in the treatment of autoimmune diseases, such as rheumatoid arthritis, psoriasis, oral lichen planus, and Sjogren's syndrome. TGP has a variety of pharmacological effects related to PRA traditional effects, including anti-organ-damage, anti-inflammatory, analgesic, antioxidant, cardiovascular, and nervous-system protection. Previously published reports on TGP treatment of autoimmune diseases have shown that TGP regulates intracellular pathways, such as the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), mitogen-activated protein kinase (MAPK), and phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathways. However, there is no standardized preparation method for TGP, and there is insufficient quality control of formulations. Many related pharmacological studies have not tested TGP components, and the validity of such pharmacological results requires further verification. CONCLUSIONS Modern pharmacological research on TGP is based on the traditional usage of PRA, and its folk medicinal value in the treatment of autoimmune diseases has now been verified. In particular, TGP has been developed into a formulation used clinically for the treatment of autoimmune diseases. The combination of TGP capsules and chemicals to treat autoimmune diseases has the effect of increasing efficacy and reducing toxicity. Based on further research on its preparation, quality control, and mechanisms of action, TGP is expected to eventually play a greater role in the treatment of autoimmune diseases.

CP-25 reverses prostaglandin E4 receptor desensitization-induced fibroblast-like synoviocyte dysfunction via the G protein-coupled receptor kinase 2 in autoimmune arthritis. Acta Pharmacol Sin 2019; 40:1029-1039.

Abstract
Paeoniflorin-6'-O-benzene sulfonate (CP-25) is a novel compound derived from paeoniflorin that has been demonstrated to have therapeutic effects in a rat model of rheumatoid arthritis (RA). However, the underlying mechanism has not been elucidated to date. We explored this mechanism in the present study by treating rats with adjuvant arthritis (AA) with CP-25. We found that the membrane EP4 protein level was downregulated; whereas, GRK2 was upregulated, in fibroblast-like synoviocyte (FLS)s of AA rats. Prostaglandin (PGE)2 stimulated FLS proliferation and enhanced the membrane EP4 receptor protein level; the latter was reversed by the administration of an EP4 receptor agonist, whereas the membrane GRK2 protein level gradually increased. The changes in the EP4 receptor and GRK2 expression were enhanced by TNF-α, and the former was accompanied by an alteration in the cyclic (c)AMP level. The EP4 receptor agonist stimulation increased the association between GRK2 and the EP4 receptor. GRK2 knockdown abrogated the abnormalities in FLS proliferation. The CP-25 treatment (100 mg/kg) suppressed joint inflammation with an efficacy that was similar to that of methotrexate. This finding was associated with EP4 upregulation and GRK2 downregulation in FLSs. Thus, GRK2 plays an important role in the abnormal FLS proliferation observed in AA possibly by promoting EP4 receptor desensitization and decreasing the cAMP level. Our results demonstrate that CP-25 has therapeutic potential for the treatment of human RA via GRK2 regulation.

Efficacy and safety of total glucosides of paeony combined with methotrexate and leflunomide for active rheumatoid arthritis: a meta-analysis. DRUG DESIGN DEVELOPMENT AND THERAPY 2019; 13:1969-1984. [PMID: 31354242 PMCID: PMC6588713 DOI: 10.2147/dddt.s207226] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Accepted: 04/30/2019] [Indexed: 12/11/2022]
Abstract
Purpose: Total glucosides of paeony (TGP) have been confirmed to reduce hepatotoxicity caused by methotrexate (MTX) and leflunomide (LEF) in rheumatoid arthritis (RA). Nevertheless, high-quality evidence-based meta-analysis data on the issue are unavailable. This study aimed to evaluate the efficacy and safety of this combination treatment for RA. Materials and methods: PubMed, EMBASE, Web of Science, Cochrane Library, ClinicalTrials, Chinese Biomedical Literature database, China National Knowledge Internet, Wan Fang, and VIP were searched up to February 2019. Randomized controlled trials (RCTs) on the efficacy and safety of TGP combined MTX and LEF for RA were included. Results: Eight RCTs were included in the final meta-analysis. Pooled results showed better therapeutic effects against RA in the TGP-treated group (RR =1.10, 95% CI: 1.04 −1.16). The TGP+MTX+LEF group showed a reduced erythrocyte sedimentation rate (MD = −2.80 mm/h, 95% CI: −5.08 - −0.52), C-reactive protein level (MD = −4.17 mg/L, 95% CI: −7.84 - −0.51), and rheumatoid factor (MD = −12.09 IU/mL, 95% CI: −14.05 - −10.14). Besides, the combination treatment tended to benefit lipid profiles (total cholesterol: 95% CI: −1.27–0.06; triglycerides: 95% CI: −0.49 - −0.08; high-density lipoprotein cholesterol: 95% CI: 0.15–0.83; and low-density lipoprotein cholesterol: 95% CI: −0.54 - −0.02). Adverse events, hepatotoxicity in particular, significantly decreased (RR =0.55, 95% CI: 0.38–0.80) in the TGP group. Conclusion: Compared to MTX and LEF therapy, TGP combination treatment may be a more effective and safer strategy. It is advisable to apply TGP as an adjuvant given its hepatoprotective and possible lipid-regulating effect. However, further large-scale and high-quality clinical trials are warranted, and the efficacy of TGP in terms of its effect on lipid profiles should be further confirmed.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory and systemic autoimmune disease with an unknown aetiology. Accumulative studies suggest that the pathogenesis of RA involves the excessive activation of synoviocytes and immune cells, increasing the secretion of inflammatory mediators and cytokines in synoviocytes, causing dysfunctional E-prostanoid (EP)-G-protein-cyclic adenosine monophosphate (cAMP) and mitogen-associated-protein kinase (MAPK) signalling in synoviocytes. Total glucosides of paeony (TGP) extracted from the roots of Paeonia lactiflora Pall, was approved by the China Food and Drug Administration as an anti-inflammatory and immuno-modulator drug in 1998. Paeoniflorin (Pae), a water-soluble monoterpene glucoside,is the main effective component of TGP. TGP and Pae produce anti-inflammatory and immuno-regulatory effects by suppressing immune cells and synoviocytes activation, decreasing inflammatory substance production and restoring abnormal signalling in synoviocytes. In this review, the regulation of the inflammatory-immune responses and the therapeutic mechanism between RA and TGP and Pae are discussed in detail. The aim of this review was to provide novel insights into the treatment of RA.

Abstract
Total glucosides of paeony (TGP) are active components extracted from the roots
of Paeonia lactiflora Pall. In this study, we
investigated the role and mechanisms of TGP in experimental autoimmune uveitis
(EAU) model of mice. The C57BL/6 mice were randomly divided into three groups:
sham group, EAU-control group, and EAU-TGP group. Clinical score of images of
the eye fundus were taken on 7, 14, 21, and 28 days after induction of EAU. The
concentrations of proinflammatory cytokines in intraocular fluid were measured
at 14 days after EAU induction with the use of a multiplex assay system. Flow
cytometry was used to analyze the frequency of CD4+, CD8+, interferon-gamma
(IFN-γ), and CD4+/CD8+ ratio in spleen and lymph nodes. Western blotting was
used to measure expressions of mitogen-activated protein kinase (MAPK)
pathway-related proteins in retina. Clinical scores for uveitis were lower in
TGP-treated EAU mice than those without TGP treatment. Importantly, the
concentrations of cytokines induced by T-helper 1 (Th1) and T-helper 2 (Th2)
cells in intraocular fluid were reduced in EAU mice treated with TGP.
Furthermore, the frequency of CD4+, IFN-γ, and CD4+/CD8+ ratio was decreased and
the frequency of CD8+ was increased in spleen and lymph nodes of mice treated
with TGP. The anti-inflammatory effects of TGP were mediated by inhibiting the
MAPK signaling pathways. Our results showed that TGP suppressed uveitis in mice
via the inhibition of Th1 and Th2 cell function. Thus, TGP may be a promising
therapeutic strategy for uveitis, as well as other ocular inflammatory
diseases.

Abstract
Paeoniflorin-6’-O-benzene sulfonate (CP-25) is a modified paeoniflorin, which is the main bioactive component of total glucosides of peony. This study evaluated the anti-inflammatory and immunoregulatory effects of CP-25 in mice with collagen-induced arthritis (CIA) and the potential mechanisms underlying these effects. After the onset of CIA, mice were given CP-25 (17.5, 35, or 70 mg/kg) or methotrexate (MTX, 2.0 mg/kg). The arthritis index, swollen joint count, and joint and spleen histopathology were evaluated. T and B cell subsets were assayed using flow cytometry, while the proliferation of these cells and fibroblast-like synoviocytes (FLSs) were evaluated using the Cell Counting Kit-8. β2-adrenoceptor (β2-AR) expression was assayed using flow cytometry, immunohistochemistry, and western blotting. FLS migration and invasion were assayed using Transwells. CP-25 (35 or 70 mg/kg) attenuated the arthritis index and swollen joint count, alleviated joint and spleen histopathology, suppressed excessive T cell activation, and attenuated humoral immunity in CIA mice. CP-25 increased β2-AR expression on T cells, B cells, dendritic cells, and the synovium in CIA mice. CP-25 up-regulated the β2-AR agonist response and attenuated FLS activation; these effects may reflect CP-25-mediated reduction of β2-AR desensitization due to down-regulation of membrane G protein-coupled receptor kinase 2 expression. These results suggest that CP-25 suppressed immune responses and synovium inflammation in mice with CIA, effects that were associated with reduced β2-AR desensitization and the promotion of β2-AR signaling.

Abstract
Previous studies demonstrated that inflammatory microenvironment promoted prostate cancer progression. This study investigated whether total glucosides of paeony (TGP), the active constituents extracted from the root of Paeonia Lactiflora Pall, suppressed lipopolysaccharide (LPS)-stimulated proliferation, migration and invasion in androgen insensitive prostate cancer cells. PC-3 cells were incubated with LPS (2.0 μg/mL) in the absence or presence of TGP (312.5 μg /mL). As expected, cells at S phase and nuclear CyclinD1, the markers of cell proliferation, were increased in LPS-stimulated PC-3 cells. Migration activity, as determined by wound-healing assay and transwell migration assay, and invasion activity, as determined by transwell invasion assay, were elevated in LPS-stimulated PC-3 cells. Interestingly, TGP suppressed LPS-stimulated PC-3 cells proliferation. Moreover, TGP inhibited LPS-stimulated migration and invasion of PC-3 cells. Additional experiment showed that TGP inhibited activation of nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK)/p38 in LPS-stimulated PC-3 cells. Correspondingly, TGP attenuated upregulation of interleukin (IL)-6 and IL-8 in LPS-stimulated PC-3 cells. In addition, TGP inhibited nuclear translocation of signal transducer and activator of transcription 3 (STAT3) in LPS-stimulated PC-3 cells. These results suggest that TGP inhibits inflammation-associated STAT3 activation and proliferation, migration and invasion in androgen insensitive prostate cancer cells.

[PMID: 28748514 PMCID: PMC5754451 DOI: 10.1007/s10067-017-3770-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2017] [Revised: 07/08/2017] [Accepted: 07/18/2017] [Indexed: 02/08/2023]
Abstract
To assess the efficacy and safety of the combination of total glucoside of peony (TGP) and methotrexate (MTX) for the treatment of rheumatoid arthritis (RA). Randomized controlled trial (RCT) data on the traditional Chinese active component TGP combined with MTX vs. MTX alone for the treatment of RA was collected by searching the Pubmed, Embase, Cochrane Library, CNKI, VIP Journals database, and Wanfang database up to February 2017. Study selection, data extraction, data synthesis, and data analyses were performed according to the Cochrane standards. A total of eight RCTs involving 522 participants were included in this meta-analysis. Compared with MTX alone, the use of TGP combined with MTX exhibited better therapeutic effects for the treatment of RA (P = 0.004). In addition, TGP combined with MTX caused a more significant decrease in erythrocyte sedimentation rate (ESR) (P < 0.0001) and swollen joint count (SJC) (P < 0.00001). However, no significant differences were found in C-reactive protein (CRP) (P = 0.19), duration of morning stiffness (DMS) (P = 0.32), or tender joint count (TJC) (P = 0.23) between the two groups. In addition, adverse events were more frequently reported in the MTX monotherapy group than in the TGP and MTX combination group (P = 0.0007). Our study demonstrates that TGP combined with MTX is more effective than MTX alone for the treatment of RA. Nevertheless, the adverse effects of the combination of TGP and MTX need to be further assessed. Due to the poor methodological quality of included trials, well-designed, multi-center, and large-scale RCTs are necessary to draw a more definitive conclusion.

Is macrophage polarization important in rheumatoid arthritis? Int Immunopharmacol 2017; 50:345-352. [PMID: 28750350 DOI: 10.1016/j.intimp.2017.07.019] [Citation(s) in RCA: 77] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2017] [Revised: 07/16/2017] [Accepted: 07/19/2017] [Indexed: 12/15/2022]
Abstract
Macrophages are myeloid immune cells which are strategically positioned throughout the body, where they engulf and degrade debris, dead cells, and foreign substances, and coordinating the inflammatory processes. Macrophages can be divided into two extreme subsets, classical activation (M1), and alternatively activation (M2). The symptoms and signs of rheumatoid arthritis (RA) would exacerbate with the increase in pro-inflammatory cytokines, whereas anti-inflammatory cytokines will alleviate the symptoms and signs of RA. This review, mainly discusses the effects of Notch, JNK and ERK signaling pathways on the regulation of macrophage polarization, and the effects of pro-inflammatory factors and/or anti-inflammatory cytokines produced by polarized macrophages in RA. Also, we will make an attempt to find out the importance of macrophage polarization in RA treatment as a drug target.

Abstract
Susceptibility of gastrointestinal dysmotility increases with age-associated colonic degeneration. A paucity of remedies reversing colonic degeneration per se hinders the fundamental relief of symptoms. Here we discovered the correlation between colon degeneration and altered nicotinamide adenine dinucleotide (NAD) level in aged mice. Compared to 3-month-old young controls, 2-year-old mice showed a spectrum of degenerative colonic phenotypes and exhibited a significant elongated transit time and slowed stool frequency in the context of Lomotil-induced slow-transit constipation. Despite upregulated colonic tryptophan hydroxylases expression, serotonin release and expression of colon-predominant type IV serotonin receptor, reduced viability of interstitial cells of Cajal while enhanced aquaporins (Aqp1, 3 and 11) led to a less colonic motility and increased luminal dehydration in aged mice. Notably, this colonic degeneration was accompanied with reduced key NAD+-generating enzyme expression and lowered NAD+/NADH ratio in aged colon. Three-month continuous administration of beta nicotinamide mononucleotide, a NAD+ precursor, elevated colonic NAD+ level and improved defecation in aged mice. In contrast, pharmacological inhibition of nicotinamide phosphoribosyltransferase, the rate-limiting enzyme for NAD+ biosynthesis, induced a reduction in colonic NAD content and impaired gastrointestinal function in young mice. Taken together, these findings suggest the beneficial effect of NAD+ in maintaining colonic homoeostasis and reactivating NAD+ biosynthesis may represent a promising strategy to counteract age-related gastrointestinal degeneration.

Abstract
Objectives Using an atropine-diphenoxylate-induced slow transit constipation (STC) model, this study explored the effects of the total glucosides of paeony (TGP) in the treatment of STC and the possible mechanisms. Study Design A prospective experimental animal study. Methods The constipation model was set up in rats with an oral gavage of atropine-diphenoxylate and then treated with the TGP. The volume and moisture content of the faeces were observed and the intestinal kinetic power was evaluated. Meanwhile, the colorimetric method and enzyme linked immunosorbent assay (ELISA) were employed to determine the changes of nitric oxide (NO), nitric oxide synthase (NOS), vasoative intestinal peptide (VIP) and the P substance (SP) in the serum, respectively. The protein expressions of c-kit and stem cell factor (SCF) were assessed by immunohistochemical analysis and western blot, respectively, and the mRNA level of c-kit was measured by a reverse transcription polymerase chain reaction (RT-PCR). Results The TGP attenuated STC responses in terms of an increase in the fecal volume and moisture content, an enhancement of intestinal transit rate and the reduction of NO, NOS and VIP in the serum. In addition, the c-kit, a labeling of interstitial cells of Cajal (ICC) increased at both protein and mRNA levels. SCF, which serves as a ligand of c-kit also increased at protein level. Conclusion The analysis of our data indicated that the TGP could obviously attenuate STC through improving the function of ICC and blocking the inhibitory neurotransmitters such as NO, NOS and VIP.

Assessment of the Therapeutic Effect of Total Glucosides of Peony for Juvenile Idiopathic Arthritis: A Systematic Review and Meta-Analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2016; 2016:8292486.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children; some clinical trials have reported the effects of total glucosides of peony (TGP) in the treatment of JIA. However, no systematic review has yet been conducted. In this study, we assessed the efficacy and safety in patients with JIA enrolled in randomized controlled trials (RCTs) of TGP. We extracted data for studies searched from 8 electronic databases that were searched and also evaluated the methodological quality of the included studies. We assessed the following outcome measures: overall response rate, pain, tender joint count (TJC), swollen joint count (SJC), duration of morning stiffness (DMS), grip strength (GS), rheumatoid factor (RF), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and adverse effects (AEs) in short term (4-8 weeks), intermediate term (9-26 weeks), and long term (>26 weeks). The final analysis showed that TGP acted as a unique nonbiologic disease-modifying antirheumatic drug (nonbiologic DMARD), and its therapeutic effects were safe and efficacious for the treatment of JIA with few AEs. However, more high-quality RCTs are needed to confirm these therapeutic effects.

Abstract
Paeoniflorin-6′-O-benzene sulfonate (code: CP-25), a novel ester derivative of paeoniflorin (Pae), was evaluated in rats with adjuvant-induced arthritis (AA) to study its potential anti-arthritic activity. AA rats were treated with CP-25 (25, 50, or 100 mg/kg) from days 17 to 29 after immunization. CP-25 effectively reduced clinical and histopathological scores compared with the AA groups. CP-25-treated rats exhibited decreases in pro-inflammatory cytokines (IL-1β, IL-6, IL-17 and TNF-α) coupled with an increase in the anti-inflammatory cytokine TGF-β1 in the serum. CP-25 treatment inhibited M1 macrophage activation and enhanced M2 macrophage activation by influencing cytokine production. Decreases in Th17-IL-17 and the Th17-associated transcription factor RAR-related orphan receptor gamma (ROR-γt) dramatically demonstrated the immunomodulatory effects of CP-25 on abnormal immune dysfunction. In addition, CP-25 suppressed the production of receptor activator of nuclear factor kappa B ligand (RANKL) and matrix metalloproteinase (MMP) 9, which supported its anti-osteoclastic effects. The data presented here demonstrated that CP-25 significantly inhibited the progression of rat AA by reducing inflammation, immunity and bone damage. The protective effects of CP-25 in AA highlight its potential as an ideal new anti-arthritic agent for human RA.

Abstract
Objective. To evaluate the efficacy and safety of the total glucosides of peony (TGP) and leflunomide (LEF) for the treatment of rheumatoid arthritis (RA). Methods. Randomized controlled trials (RCTs) on the efficacy and safety of the combination of TGP and LEF versus LEF alone for the treatment of RA were retrieved by searching PubMed, EMBASE, Cochrane Library, the China National Knowledge Infrastructure database, and Wanfang database. Results. Eight RCTs including 643 RA patients were included in the present meta-analysis. The quality of included studies was poor. The levels of ESR (P < 0.0001), CRP (P < 0.0001), and RF (P < 0.0001) in RA patients who received the combination of TGP and LEF were significantly lower than RA patients who received LEF therapy alone. The pooled results suggest that the combination of TGP and LEF caused less abnormal liver function than LEF alone (P = 0.02). No significant difference in the gastrointestinal discomfort was identified between the combination of TGP and LEF and LEF alone groups (P = 0.18). Conclusion. The combination of TGP and LEF in treatment of RA presented the characteristics of notably decreasing the levels of laboratory indexes and higher safety in terms of liver function. However, this conclusion should be further investigated based on a larger sample size.

Abstract
Total glucosides of peony (TGP), an active compound extracted from the roots of Paeonia lactiflora Pall, has wide pharmacological effects on nervous system. Here we examined the effects of TGP on experimental autoimmune encephalomyelitis (EAE), an established model of multiple sclerosis (MS). The results showed that TGP can reduce the severity and progression of EAE in C57 BL/6 mice. In addition, TGP also down-regulated the Th1/Th17 inflammatory response and prevented the reduced expression of brain-derived neurotrophic factor and 2',3'-cyclic nucleotide 3'-phosphodiesterase of EAE. These findings suggest that TGP could be a potential therapeutic agent for MS.

A UPLC-MS/MS method for simultaneous quantitation of three monoterpene glycosides and four alkaloids in rat plasma: application to a comparative pharmacokinetic study of Huo Luo Xiao Ling Dan and single herb extract. JOURNAL OF MASS SPECTROMETRY : JMS 2015; 50:567-577. [PMID: 25800193 DOI: 10.1002/jms.3563] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2014] [Revised: 12/07/2014] [Accepted: 12/09/2014] [Indexed: 06/04/2023]
Abstract
The objective of this study was to develop a sensitive and reliable ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for simultaneous quantitation of three monoterpene glycosides (paeoniflorin, alibiflorin and oxypaeoniflorin) and four alkaloids (tetrahydropalmatine, corydaline, dehydrocorydaline and berberine), the main active ingredients of Radix Paeoniae Rubra extract (RPE) and Corydalis yanhusuo extract (CYE) in Huo Luo Xiao Ling Dan (HLXLD), and to compare the pharmacokinetics of these active ingredients in normal and arthritic rats orally administrated with HLXLD or RPE/CYE alone. The analytes and internal standard (IS) (geniposide) were separated on a XBridge C18 column (150 × 4.6 mm, 3.5 µm) using gradient elution with the mobile phase consisting of methanol and 0.01% formic acid in water at a flow rate of 0.6 ml/min. The detection of the analytes was performed on Acquity UPLC-MS/MS system with an electrospray ionization and multiple reaction monitoring mode via polarity switching between negative (for monoterpene glycosides) and positive (for alkaloids) ionization mode. The lower limits of quantification were 2.5, 1, 0.5, 0.2, 0.2, 0.02 and 0.01 ng/ml for paeoniflorin, alibiflorin, oxypaeoniflorin, tetrahydropalmatine, corydaline, dehydrocorydaline and berberine, respectively. Intra-day and inter-day precision and accuracy of analytes were well within acceptance criteria (15%). The mean extraction recoveries of analytes and IS from rat plasma were all more than 83.1%. The validated method has been successfully applied to determination of the analytes. Results showed that there were remarkable differences in pharmacokinetic properties of the analytes between herbal formula and single herb group, normal and arthritic group.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Costus afer Ker Gawl is an indigenous tropical African medicinal plant used as therapy in the treatment of inflammatory ailments such as rheumatoid arthritis. This study was designed to evaluate the anti-inflammatory and antioxidant activities of the hexane fraction of C. afer leaves (CAHLF). MATERIALS AND METHODS The anti-inflammatory effect of varying doses of CAHLF on carrageenan, arachidonic acid, and formaldehyde induced arthritis in male albino rats׳ models were investigated in order to study the acute inflammatory phase. Complete Freund׳s Adjuvant (CFA)-induced arthritis model was used to study the chronic inflammatory phase. Two known anti-inflammatory drugs, Diclofenac sodium (non-steroidal anti-inflammatory drug [NSAID]) and prednisolone (glucocorticoid [steroidal drug]) were used as standards for comparison. Various biochemical indices viz. superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), reduced glutathione (GSH) and malondialdehyde (MDA), aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total bilirubin (TB), total protein (TP), globulin and albumin levels were assayed using spectrophotometric methods. RESULTS Control animals in which arthritis have been induced using carrageenan, arachidonic acid, formaldehyde or CFA showed significant increases (P<0.05) in paw edema when compared with normal animals. Treatment of the arthritis induced rats with CAHLF significantly (P<0.05) suppressed the edema. in vivo antioxidant study showed that CAHLF treated animals had a significantly (P<0.05) elevated GSH level, SOD, CAT and GST activities while MDA levels were significantly (P<0.05) reduced in the plasma, liver, kidney and brain. CAHLF treated rats had a significantly (P<0.05) reduced plasma AST, ALT and ALP. Plasma TP, globulin, TB levels were reduced while albumin levels were elevated in CAHLF treated animals. CONCLUSIONS CAHLF possesses substantial anti-inflammatory and antioxidant activities against inflammatory diseases especially arthritis. It could be considered as a choice candidate in pharmaceutical anti-inflammatory drug development.

Abstract
There is a growing concern for the sensitive quantification of multiple components using advanced data acquisition method in herbal medicines (HMs). An improved and rugged UPLC-MS/MS method has been developed and validated for sensitive and rapid determination of multiply analytes from Tong-Xie-Yao-Fang (TXYF) decoction in three biological matrices (plasma/brain tissue/urine) using geniposide and formononetin as internal standards. After solid-phase extraction, chromatographic separation was performed on a C18 column using gradient elution. Quantifier and qualifier transitions were monitored using novel Triggered Dynamic multiple reaction monitoring (TdMRM) in the positive ionization mode. A significant peak symmetry and sensitivity improvement in the TdMRM mode was achieved as compared to conventional MRM. The reproducibility (RSD%) was ≤7.9% by applying TdMRM transition while the values were 6.8-20.6% for MRM. Excellent linear calibration curves were obtained under TdMRM transitions over the tested concentration ranges. Intra- and inter-day precisions (RSD%) were ≤14.2% and accuracies (RE%) ranged from -9.6% to 10.6%. The validation data of specificity, carryover, recovery, matrix effect and stability were within the required limits. The method was effectively applied to simultaneously detect and quantify 1 lactone, 2 monoterpene glucosides, 1 alkaloid, 5 flavonoids and 2 chromones in plasma, brain tissue and urine after oral administration of TXYF decoction. In conclusion, this new and reliable method is beneficial for quantification and confirmation assays of multiply components in complex biological samples.

Total glucosides of paeony inhibit the proliferation of fibroblast-like synoviocytes through the regulation of G proteins in rats with collagen-induced arthritis. Int Immunopharmacol 2013; 18:1-6. [PMID: 24161745 DOI: 10.1016/j.intimp.2013.09.007] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2013] [Revised: 09/02/2013] [Accepted: 09/04/2013] [Indexed: 01/29/2023]
Abstract
The aim of this study was to investigate the expression of G proteins in fibroblast-like synoviocytes (FLSs) from rats with collagen-induced arthritis (CIA) and to determine the effect of total glucosides of paeony (TGP). CIA rats were induced with chicken type II collagen (CCII) in Freund's complete adjuvant. The rats with experimental arthritis were randomly separated into five groups and then treated with TGP (25, 50, and 100mg/kg) from days 14 to 35 after immunization. The secondary inflammatory reactions were evaluated through the polyarthritis index and histopathological changes. The level of cyclic adenosine monophosphate (cAMP) was measured by radioimmunoassay. The FLS proliferation response was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The toxin-catalyzed ADP-ribosylation of G proteins was performed through autoradiography. The results show that TGP (25, 50, and 100mg/kg) significantly decreased the arthritis scores of CIA rats and improved the histopathological changes. TGP inhibited the proliferation of FLSs and increased the level of cAMP. Moreover, the FLS proliferation and the level of Gαi expression were significantly increased, but the level of Gαs expression was decreased after stimulation with IL-1β (10ng/ml) in vitro. TGP (12.5 and 62.5μg/ml) significantly inhibited the FLS proliferation and regulated the balance between Gαi and Gαs. These results demonstrate that TGP may exert its anti-inflammatory effects through the suppression of FLS proliferation, which may be associated with its ability to regulate the balance of G proteins. Thus, TGP may have potential as a therapeutic agent for the treatment of rheumatoid arthritis.

Abstract
Because depression is associated with significant morbidity and functional disability, it is important to reveal the mechanism of action. A variety of studies have suggested the involvement of dopaminergic receptors in the pathophysiological mechanism of non-stress-associated depression-like behavior in rodents. Nevertheless, controversy exists about whether chronic stress acts on dopaminergic receptors in the prefrontal cortex. Thus, we investigated the level of dopamine D2 receptors (DRD2) and the possible mechanisms involved in a chronic unpredictable mild stress (CUMS) rat model of depression. The results showed CUMS-induced, depression-like symptoms in the rat, characterized by reduced sucrose consumption and body mass, and increased duration of immobility in a forced swimming test. Moreover, chronic stress upregulated the expression of DRD2 but downregulated protein kinase A (PKA), transcription factor cAMP response element binding protein (CREB), and phospho-CREB (p-CREB) in the prefrontal cortex, as demonstrated by Western blot. Notably, in the rat model of depression, decreased cyclic adenine monophosphate (cAMP) levels and PKA activity were present at the same time, which is consistent with clinical findings in depressed patients. Our findings suggested that dopaminergic system dysfunction could play a central role in stress-related disorders such as depression.

Abstract
Background Total glucosides of paeony (TGP) is a biologically active compound extracted from Paeony root. TGP has been used in rheumatoid arthritis therapy for many years. However, the mechanism by which TGP prevents bone loss has been less explored. Methods TGP was orally administered for 3 months to New Zealand rabbits with antigen-induced arthritis (AIA). Digital x-ray knee images and bone mineral density (BMD) measurements of the subchondral knee bone were performed before sacrifice. Chondrocytes were observed using transmission electron microscopy (TEM). Histological analysis and mRNA expression of receptor activator of nuclear factor-B ligand (RANKL) and osteoprotegerin (OPG) were evaluated in joint tissues. Results The BMD value in TGP rabbits was significantly higher compared with that seen in the AIA model rabbits. In addition, the subchondral bone plate was almost completely preserved by TGP treatment, while there was a decrease in bone plate integrity in AIA rabbits. There was less damage to the chondrocytes of the TGP treated group. Immunohistochemical examination of the TGP group showed that a higher percentage of TGP treated chondrocytes expressed OPG as compared to the chondrocytes isolated from AIA treated animals. In contrast, RANKL expression was significantly decreased in the TGP treated group compared to the AIA group. In support of the immunohistochemistry data, the expression of RANKL mRNA was decreased and OPG mRNA expression was enhanced in the TGP group when compared to that of the AIA model group. Conclusion These results reveal that TGP suppresses juxta-articular osteoporosis and prevents subchondral bone loss. The decreased RANKL and increased OPG expression seen in TGP treated animals could explain how administration of TGP maintains higher BMD.

Abstract
Total glucosides of paeony (TGP) is the major active constituent of Paeonia lactiflora Pall., which has shown renoprotection in experimental diabetic nephropathy. Activation of Janus kinase/signal transducers and activators of transcription (JAK/STAT) is an important mechanism by which hyperglycemia contributes to renal damage. Macrophages also play an essential role in the pathogenesis of diabetic nephropathy. Herein, we investigated the ability of TGP to modulate JAK2/STAT3 activation and macrophage proliferation in rats with streptozotocin (STZ)-induced diabetes. TGP (50, 100, and 200 mg/kg) was administered orally once a day for eight weeks. Levels of p-JAK2 and p-STAT3 were determined by Western blot analysis. Immunohistochemistry and double immunohistochemistry were used to identify p-STAT3, ED-1, PCNA/ED-1, and p-STAT3/ED-1-positive (+) cells. The elevated 24-h urinary albumin excretion rate was markedly attenuated by treatment with 50, 100, and 200 mg/kg TGP. Western blot analysis showed that the significantly increased levels of p-JAK2, p-STAT3 proteins in the kidneys of diabetic rats were significantly inhibited by 50, 100, and 200 mg/kg TGP treatment. The marked accumulation and proliferation of macrophages in diabetic kidneys were significantly inhibited by TGP treatment. ED-1+/p-STAT3+ cells were significantly increased in the kidneys from the model group but were significantly inhibited by TGP treatment. These results show that TGP significantly inhibited diabetic nephropathy progression and suggest that these protective effects are associated with the ability of TGP to inhibit the JAK2/STAT3 pathway and macrophage proliferation and action.

[PMID: 22483552 DOI: 10.1016/j.phymed.2012.03.004] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/08/2011] [Revised: 02/02/2012] [Accepted: 03/04/2012] [Indexed: 05/31/2023]
Abstract
Paeoniae radix is a traditional Chinese medicinal herb for treating some diseases; important components are total paeony glycosides (TPGs), an approved drug by the State Food and Drug Administration (SFDA) for the therapy of rheumatoid arthritis (RA). We firstly reported myocardial benefits of TPGs previously, and the present study is to further investigate the underlying mechanisms for preventing oxidative damage in cardiomyopathy. We measured the capacity of TPGs to scavenge free radicals in vitro. Then 60 SD rats were randomly divided into five groups: (1) a normal control group, (2) an isoprenaline (ISO)-induced myocardial ischemic model group, (3) a TPG treatment group (TPGs 269.4 mg/kg delivered by intragastric administration for 3 days before ISO administration and TPGs 449 mg/kg delivered for 3 days after ISO administration), (4) a TPG therapy group (TPGs 449 mg/kg delivered for 3 days after ISO administration), and (5) a positive control group (propranolol 15 mg/kg for 3 days after ISO administration). The ISO-induced myocardial ischemic model was established by subcutaneous injection of 1mg/kg/8h ISO (2 times). The activities of myocardial enzymes, including glutamic oxaloacetic transaminase (GOT), creatine kinase (CK), lactate dehydrogenase (LDH), antioxidant enzyme superoxide dismutase (SOD) as well as the content of lipid peroxidation product malondialdehyde (MDA) were detected. We found that TPGs potently eliminated hydroxyl radicals and superoxide in vitro using ESR assays. Compared with model rats, TPG treatment, TPG therapy and the positive control treatment exhibited significantly reduced activities of GOT, LDH, and CK (p < 0.01), increased activity of SOD (p < 0.01) and lower levels of MDA (p < 0.05). More interestingly, the protective effect of TPG treatment was even better than that of propranolol. These results suggest that TPGs significantly ameliorate ISO-induced myocardial ischemia and their action might be through reducing oxidative stress in ischemic myocardium.

Abstract
BACKGROUND Contact dermatitises, including allergic contact dermatitis and irritant contact dermatitis, are among the most common skin disorders in humans. Chinese herbal medicines (CHM) have been used in treating contact dermatitises for centuries. Systemic administration of CHM, including ingredients in huangdang mixture containing Chinese angelica, radix Paeonlae rubra, cat nut, and phelloden dron, rhizoma alismatis, rhizoma smilacis glabrae, and rhizome of swordlike, improves allergic contact dermatitis induced by l-fluoro-2,4-dinitrobenzene. Whether topical applications of these herbal extracts display preventive and/or therapeutic effects on contact dermatitis, thereby avoiding the potential side effects of systemic CHM, remains largely unknown. AIMS To determine whether this topical CHM extract exerts preventive and/or therapeutic effects, we assessed its efficacy in both allergic contact dermatitis and irritant contact dermatitis murine models. MATERIALS AND METHODS Allergic contact dermatitis and irritant contact dermatitis murine models were established by topical oxazolone and a phorbol ester (12-O-tetradecanoylphorbol-13-acetate; TPA), respectively. Ear thickness was assessed in both dermatitis models. RESULTS Our results demonstrate that this topical CHM extract exhibits both therapeutic and preventive effects in acute irritant contact dermatitis but no demonstrable efficacy in murine allergic contact dermatitis. CONCLUSION These results suggest that this topical CHM extract could provide an alternative regimen for the prevention and treatment of irritant contact dermatitis.

Int Immunopharmacol 2012; 12:701-6.

Abstract
The aim of this study was to explore the expression and function of β-arrestin 2 in human fibroblast-like synoviocytes (FLS) stimulated by IL-1β and the effect of paeoniflorin (Pae). We isolated and cultured human FLS, which were stimulated by IL-1β. The FLS proliferations were detected by [3H] thymidine incorporation. The level of cAMP stimulated by IL-1β on different times was investigated by radioimmunoassay, and the activity of PKA was measured by luminescent kinase assay. The expression of β-arrestin 2 was measured by western blot. We found that the human FLS proliferation increased apparently in 24 h, and the activities of PKA and cAMP accumulation increased significantly in 6 h after stimulated by IL-1β, while cAMP accumulation and the activities of PKA decreased especially in 24 h when the expression of β-arrestin 2 increased significantly. Decreased cAMP accumulation and the increased expression of β-arrestin 2 may reveal a positive correlation with the FLS proliferation. Pae (10(-5), 10(-6), 10-7 mol•L(-1)) in vitro could suppress the FLS proliferation and the high expression of β-arrestin 2. The expression of β-arrestin 2 may have a positive correlation with the human FLS proliferation, while the activities of PKA and cAMP accumulation have a negative correlation with the proliferation. The increased β-arrestin 2 may down-regulate cAMP-PKA signaling pathway and promote FLS proliferation. Pae may suppress the expression of β-arrestin 2 and up-regulate cAMP-PKA signaling, which may be one of the mechanisms for the effects of Pae on inhibiting human FLS proliferation.

Abstract
CONTEXT Depression is a common psychiatric disorder, yet the clinical efficacy of antidepression therapies is unsatisfactory. Thus, the search for new anti-depressants continues, and natural products remain a promising source of new therapeutic agents. The root part of Paeonia lactiflora Pall. (Ranunculaceae), known as peony, is often used in Chinese herbal prescriptions for the treatment of depression-like disorders. OBJECTIVES The objective of this review is to provide scientific evidence to support further research on peony as a potential anti-depressant drug. METHODS This review summarizes the results obtained in our laboratory, together with other literature data obtained through a comprehensive search in databases including PubMed, ScienceDirect, Scirus, and Web of Science. RESULTS The peony extract is active in the mouse forced swim test and tail suspension test, and it produces anti-depressant effects in chronic unpredictable mild stress-induced depression model in mice and rats. The anti-depressant mechanisms of peony are likely mediated by the inhibition of monoamine oxidase activity, neuro-protection, modulation of the function of hypothalamic-pituitary-adrenal axis, inhibition of oxidative stress, and the up-regulation of neurotrophins. CONCLUSIONS Peony is used clinically to treat depression-like symptoms in Chinese medicine, and it has been shown to possess anti-depressant property in a battery of test models using laboratory animals. Its effect is likely mediated by multiple targets. Further studies are warranted to delineate the molecular mechanisms of action, determine the pharmacokinetics, establish the toxicological profile, and assess the potentials of peony in clinical applications. Identification of the clinically active ingredient(s) is also warranted.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE To investigate the effect of the Paeoniflorin (Pae), a main active component of total glucosides of paeony (TGP) extracted from the root of Paeonia lactiflora, on regulation of synoviocytes cultured from rats collagen-induced arthritis (CIA) in vitro. MATERIALS AND METHODS CIA was induced in male Sprague-Dawley rats immunized with chicken type II collagen (CCII) in Freund's complete adjuvant. The levels of interleukin-1 (IL-1), tumor necrosis factor α (TNF-α), prostaglandin E(2) (PGE(2)) and cyclic adenosine monophosphate (cAMP) were measured by radioimmunoassay. The proliferation responses was determined by the 3-(4,5-2dimethylthiazal-2yl) 2,5-diphenyltetrazoliumbromide (MTT) assay. Expression of E-prostanoid (EP(4)) receptor was detected by Western blotting technique. RESULTS Treatment of Pae (2.5, 12.5, 62.5 μg/ml) significantly decreased the production of IL-1 and TNF-α. Recombinant interleukin-1 (rIL-1α) (10 ng/ml) apparently stimulated synoviocyte, thymocyte and splenocyte proliferation, and Pae (12.5, 62.5 μg/ml) inhibited abnormal proliferation responses stimulated by rIL-1α. Moreover, rIL-1α time- and concentration-dependently increased production of PGE(2). The production of PGE(2) produced by synoviocytes from CIA rats significantly inhibited by administration of Pae (12.5, 62.5 μg/ml). rIL-1α (10 ng/ml) decreased cAMP of synoviocytes cells treated for 24h. Similarly rIL-1α (0.1, 1, 10 ng/ml) induced a concentration-dependent decrease in the production of cAMP at 24h. Pae (12.5, 62.5 μg/ml) increased the production of cAMP in synoviocytes. The immunoblot, Pae (12.5, 62.5 μg/ml) apparently increased the expression of EP(4) receptor in synoviocytes stimulated by rIL-1α (10 ng/ml). CONCLUSIONS The present study indicates that Pae might exert its anti-inflammatory effects through suppressing synoviocytes function and regulating immune cells responses in CIA rats, which might be associated with its ability to up-regulate the E-prostanoid (EP(4)) receptor protein expression and modulate intracellular cAMP level.

Abstract
The root of Clematis chinensis Osbeck has been used widely in rheumatoid arthritis in Chinese traditional medicine, and AR-6 is a triterpene saponin isolated from it. In this present study, we investigated the in vivo effects of oral AR-6 in chronic rat with collagen-induced arthritis (CIA) and possible molecular mechanism. CIA was induced by immunizing 56 female Sprague-Dawley (SD) rats with chicken typeIIcollagen (CII). Following eighteen days, the immunization rats with CIA were treated with AR-6 (32, 16, 8 mg/kg), cyclophosphamide (7 mg/kg), and TGP (Total Glucosides of Paeonia) (180 mg/kg) for 7 days, and rats without CIA were given the same volume of purified water. TNF-α and IL-1β levels in peripheral blood will be measured by ELISA, and Western blot analysis will be used to detect the expression of NF-κB p65 subunits, TNF-α and COX-2, in synovial membrane. We found that therapeutic treatment with AR-6 markedly improves the paw swelling and histopathological changes. Moreover, the serum levels of pro-inflammatory cytokines TNF-α and IL-1β were markedly lowered, and the expression of NF-κB p65 subunits, TNF-α and COX-2, in the synovial membrane of CIA rats was significantly inhibited in the AR-6-treated groups. These results enable to prove that AR-6 has a potential anti-inflammatory effect in CIA rats, and its mechanism may relate to the inhibition of the expression of NF-κB p65 subunits, TNF-α and COX-2.

Abstract
BACKGROUND Paeonia lactiflora root (baishao in Chinese) is a commonly used herb in TCM. Research has shown baishao to have positive pharmacological actions, including, particularly, anti-inflammatory properties. In this paper we studied the influence of baishao extract on cAMP-phosphodiesterase (PDE) activity and related anti-inflammatory action to identify new pharmacologic action for its clinically widespread use. METHODS PDE activity was calculated by cAMP change examined with HPLC, respiratory burst of neutrophils was detected with method of cytochrome C reduction, elastase release was indicated with the substrate reduction, rat arthritis model was caused by complete Freund's adjuvant, mouse capillary permeability model was made by acetic acid, and chemical constituents of baishao extract was identified by HPLC, mass spectroscopy and NMR spectrum. RESULTS Baishao extract had significant inhibition on cAMP-PDE activity (p<0.01), had dose dependent restraint on neutrophils respiratory burst (p<0.001), had inhibition at low concentration and promotion at high concentration on elastase release (p<0.05), and had obvious restraint on local inflammation of animal model (p<0.01). Analysis of HPLC, mass spectroscopy and NMR spectrum showed baishao extract mainly had five components (identified as gallic acid, paeoniflorin sulfonate, albiflorin, paeoniflorin and benzoic acid), among which gallic acid had the largest inhibition on cAMP-PDE activity. CONCLUSION The anti-inflammatory effects of baishao may be mediated, at least in part, through its gallic acid content, and this effect may be regulated in part by an inhibition on cAMP-PDE.

Abstract
To explore the molecular mechanisms of human leukemia cells by total paeony glycoside (TPG), which is extracted from the root of Radix Paeoniae Rubra. The viability of K562 cells was assessed by MTT assay. Flow cytometry was used to detect apoptosis and cell cycle analysis. The changes in intracellular Ca(2+) concentration were determined by fluorescent dye Fluo-3, and mitochondrial membrane potential was determined by the retention of the dye Rh123. The cytoplasmic Bax, Bcl-xL, and Bcl-2 protein expressions were determined by western blot. The mRNA expression of caspase-3, caspase-8, and caspase-9 was detected by RT-PCR. K562 cells were subcutaneously inoculated into nude mice to study the in vivo antitumor effects of TPG. The growth of K562 cells was inhibited and arrested in G0/G1 phase by TPG. TPG also caused apoptosis in K562 cells evidenced by cytosolic accumulation of cytochrome c, caspase-9, and caspase-3. TPG could down-regulate Bcl-2 and Bcl-xL and up-regulate Bax in K562 cells. TPG showed a significant decreased tumor volume and tumor weight in nude mice inoculated with K562 cells. TPG can be developed as a promising anti-chronic myeloid leukemia drug.
