The present study was designed to examine the anti-hyperuricemic and anti-inflammatory effects and possible mechanisms of vaticaffinol, a resveratrol tetramer isolated from ethanol extracts of Dipterocarpus alatus, in oxonate-induced hyperuricemic mice. At 1 h after 250 mg·kg potassium oxonate was given, vaticaffinol at 20, 40, and 60 mg·kg was intragastrically administered to hyperuricemic mice once daily for seven consecutive days. Vaticaffinol significantly decreased serum uric acid levels and improved kidney function in hyperuricemic mice. It inhibited hepatic activity of xanthine dehydrogenase (XDH) and xanthine oxidase (XOD), regulated renal mRNA and protein levels of urate transporter 1 (URAT1), glucose transporter 9 (GLUT9), organic anion transporter 1 (OAT1), organic cation transporter 1 (OCT1), OCT2, organic cation/carnitine transporter 1 (OCTN1), and OCTN2 in hyperuricemic mice. Moreover, vaticaffinol markedly down-regulated renal protein levels of NOD-like receptor 3 (NLRP3), apoptosis-associated speck-like (ASC), and Caspase-1, resulting in the reduction of interleukin (IL)-1β, IL-18, IL-6 and tumor necrosis factor-α (TNF-α) levels in this animal model. Additionally, HPLC and LC-MS analyses clearly testified the presence of vaticaffinol in the crude extract. These results suggest that vaticaffinol may be useful for the prevention and treatment of hyperuricemia with kidney inflammation.

OBJECTIVETo determine the effective dosage and formulation of agkistrodon in collagen-induced arthritis (CIA) rats.

METHODSCIA was induced by injection of collagen in complete/incomplete Freund's adjuvant. Agkistrodon decoction, agkistrodon powder, and agkistrodon wine were administered daily starting from the onset of arthritis. Paw swelling degree was measured by using a volume-measuring instrument every 7 days after primary immunization. Arthritis index was measured and calculated using the "five scoring method" every 7 days. The levels of serum interleukin-1ß (IL-1ß) and type II collagen IgG antibodies were detected by enzyme-linked immunosorbent assay. Finally, all ankles were removed, and X-ray radiography was performed with In-vivo Imaging System FX. Samples were counterstained with hematoxylin and eosin for analysis.

RESULTSAmong the various dosage formulations of agkistrodon, high-dose powder, which was equivalent to an amount of 6 g/day in adults, showed better effects on the inhibition of joint swelling and reduction of arthritis index score. The relatively low levels of serum IL-1 and anti-type II collagen IgG antibodies, as well as the X-ray radiography and pathology results, further proved the superiority of the high-dose powder over the other formulations. The effect of decoction on inhibiting joint swelling was inversely proportional to the dosage. Other effects, such as reduction of arthritis index score and the levels of serum IL-1 and anti-type II collagen IgG antibodies, were directly proportional to the dosage. While the use of large dose agkistrodon wine led to negative effects.

CONCLUSIONThese data highlight the potential function of high-dose agkistrodon powder, which was equivalent to an amount of 6 g/day in adults. The powder can quickly relieve the symptoms of rheumatoid arthritis and prevent aggravation of disease, especially during the early period.

The aim of the study was to investigate the effects of Siwu decoction on hyperuricemia, kidney inflammation, and dysfunction in hyperuricemic mice. Siwu decoction at 363.8, 727.5, and 1 455 mg·kg(-1) was orally administered to potassium oxonate-induced hyperuricemic mice for 7 days. Serum urate, creatinine, and blood urea nitrogen levels and hepatic xanthine oxidase (XOD) activity were measured. The protein levels of hepatic XOD and renal urate transporter 1 (URAT1), glucose transporter 9 (GLUT9), organic anion transporters 1 (OAT1), ATP-binding cassette subfamily G member 2 (ABCG2), organic cation transporter 1 (OCT1), OCT2, organic cation/carnitine transporter 1 (OCTN1), OCNT2, Nod-like receptor family, pyrin domain containing 3 (NLRP3), apoptosis-associated speck-like protein (ASC), Caspase-1, and interleukin-1β (IL-1β) were determined by Western blotting. Renal histopathology change was obtained following hematoxylin-eosin staining. Our results indicated that Siwu decoction significantly reduced serum urate, creatinine and blood urea nitrogen levels and increased fractional excretion of uric acid in hyperuricemic mice. It effectively reduced hepatic XOD activity and protein levels in this animal model. Furthermore, Siwu decoction down-regulated URAT1 and GLUT9 protein levels, and up-regulated the protein levels of OAT1, ABCG2, OCT1, OCT2, OCTN1, and OCTN2 in the kidney of the hyperuricemic mice. Additionally, Siwu decoction remarkably reduced renal protein levels of NLRP3, ASC, Caspase-1, and IL-1β in the hyperuricemic mice. These results suggested that Siwu decoction exhibited anti-hyperuricemic and anti-inflammatory effects by inhibiting hepatic XOD activity, regulating renal organic ion transporter expression, and suppressing renal NLRP3 inflammasome activation, providing the evidence for its use in the treatment of hyperuricemia and associated kidney inflammation.

OBJECTIVETo investigate the effect of Qiguiyin Decoction, QGYD) on multidrug-resistant Pseudomonas aeruginosa infection in Sprague-Dawley (SD) rats.

METHODSA pseudomonal infection model in SD rats was established by injecting multidrug-resistant P. aeruginosa intraperitoneally. Infected rats were randomized into four groups treated with Pure water, QGYD, ceftazidime, or combined QGYD and ceftazidime. Blood samples were obtained from the abdominal aorta. Serum was then collected and analyzed by peptide array for immune responsiveness to multidrug-resistant beta-lactamase proteins, including Verona integronen-coded metallo-beta-lactamase 1 (VIM-1), Sao Paulo metallo-beta-lactamase 1 (SPM-1), and Temoniera (TEMs). Blood levels of interleukin-1β (IL-1β), interleukin-4 (IL-4), and interferon-γ (IFN-γ) were assessed by enzyme-linked immunosorbent assay.

RESULTSQGYD enhanced antibody reactivity against VIM-1 [epitopes 7-11 and 36-40] and TEM-1 [epitopes 26-27, 52-55, and 66-70]. QGYD treatment restored the compromised antibody reactivity against VIM-1 [epitopes 53-54 and 56-58] and SPM-1 [epitopes 16-19 and 82-85] following pseudomonal infection. Serum levels of IL-1β and Th1/Th2 in the rats were significantly elevated following pseudomonal infection (P<0.05 orP<0.01). In contrast, QGYD and combination QGYD and ceftazidime treatment restored the elevated serum IL-1β and Th1/Th2 levels to normal (P>0.05).

CONCLUSIONSQGYD improves the immune response to pseudomonal infection in rats by stimulating the production of protective antibodies against drug-resistant proteins VIM-1, SPM-1, and TEM-1. In addition, it protects the immune system and maintains immune responsiveness by restoring IL-1β and Th1/Th2 levels.

OBJECTIVETo study the effects and immunoregulation mechanism of the traditional Mongolian medicine Wuweifengshi capsule on adjuvant arthritis (AA).

METHODWister rats were divided into several groups: normal group, AA model group, Wuweifengshi capsule groups (with low, moderate, high dose of 0.2, 0.4, 0.8 g x kg(-1) x d(-1) respectively), and Zhonglun-5 group (original dose of 1.68 g x kg(-1) x d(-1)). The edema degree, the level of IL-1beta, TNF-alpha, PGE2, NO and MDA and the activity of SOD in serum were detected. Through cell culture, the effects of the medicine on AA rat's splenic cell's multiplication capacity were studied. The influence of celiac macrophage cell culture fluid of AA rats' on C57BL/6J mice thymic cell multiplication capacity under the medicine was evaluated.

RESULTWuweifengshi capsule showed an inhibiting function on the level of IL-1beta, TNF-alpha, PGE2, NO and increased the activity of SOD in serum, but showed no significant influence on MDA. It also inhibited the AA rat's splenic cell's multiplication capacity and the influence of celiac macrophage cell culture fluid of AA rat's on C57BL/6J mice thymic cell multiplication capacity.

CONCLUSIONThe anti-AA effect of Wuweifengshi capsule is possibly due to its inhibition of relevant cytokines and its adjustment of corresponding enzyme's activity and immunization organ's cell multiplication capacity.

OBJECTIVETo observe the effect of Huanglian Jiedu IJecoction (HJU) on systemic and vascular immune responses of high fat diet fed apoE deficient (apoE(-/-)) mice.

METHODSEight wild type C57BL6 mice were recruited as the wild type common food group. Totally 24 apoE(-/-) mice were randomly divided into the ApoE'common food group, the ApoE(-/-) hyperlipidemia group, and the ApoE(-/-) hyperlipidemia plus HJD group, 8 in each group. In the present study, the common food mice and high fat fed mice were fed with a chow diet or a high cholesterol diet for 4 weeks. HJD was given to mice in the ApoE(-/-) hyperlipidemia plus HJD group at the daily dose of 5 g/kg by gastrogavage, while equal volume of pure water was given to mice in the rest groups by gastrogavage. Four weeks later, the plasma levels of blood lipids, the ratio of peripheral blood mononuclear cells, and expressions of Toll-like receptor 4 (TLR-4) and CD36 on the monocytes were detected. The pathological changes and expressions of cytokines in local aorta were detected. The plasma cytokine levels in response to lipopolysaccharide (LPS) were analyzed. Results (1) Compared with the wild type common food group, TO, TG, and LDL-O significantly increased in the ApoE(-/-) common food group (P < 0. 05, P < 0.01). Compared with the ApoE(-/-) common food group, TC and LDL-C significantly increased in the hyperlipidemia group (P < 0. 05). There was no statistical difference in each index between the ApoE(-/-) hyperlipidemia group and the ApoE(-/-) hyperlipidemia plus HJD group (P > 0.05). (2) Compared with the wild type common food group, no obvious change of the ratio of peripheral blood mononuclear cells happened, the TLR4 expression level significantly increased in the ApoE'common food group (P < 0. 05). Compared with the ApoE common food group, the ratio of peripheral blood mononuclear cells and the TLR4 expression level significantly increased in the ApoE' hyperlipidemia group (P < 0.05). Compared with the ApoE(-/-) hyperlipidemia group, the ratio of peripheral blood mononuclear cells and the TLR4 expression level significantly decreased. Besides, the CD36 expression level also significantly decreased (P<0.05). (3) After stimulated by LPS for 3 h, compared with the wild type common food group, plasma TNF-ct and IL-b expressions significantly increased in the ApoE(-/-) common food group (P < 0.05). Compared with the ApoE(-/-) common food group, plasma expressions of IL-12, TNF-alpha, MCP-1, and IL-10 increased, but with no statistical difference in the ApoE(-/-) hyperlipidemia group (P > 0.05). After 4-week intervention of HJD, compared with the ApoE(-/-) hyperlipidemia group, the MCP-1 expression was significantly down-regulated, while the IL-10 expression significantly increased, showing statistical difference (P < 0.05). Compared with the wild type common food group, mRNA expression levels of IFN-gamma, MCP-1 , TNF-alpha, IL-10, and IL-1beta significantly increased (P < 0. 05, P < 0.01). Compared with the ApoE(-/-) common food group, not only mRNA expression levels of IFN-gamma, MCP-1, TNF-alpha, and IL-1beta, further significantly increased, but also IL-12, IL-10, and TGF-beta significantly increased (P < 0. 05, P < 0. 01). After 4-week intervention of HJD, compared with the ApoE(-/-) hyperlipidemia group, mRNA expression levels of MCP-1, TNF-alpha, IL-1beta, and IL-12 significantly decreased in the ApoE(-/-) hyperlipidemia plus HJD group (P < 0.05, P < 0.01).

CONCLUSIONSHigh fat diet induced systemic reaction and inflammatory reactions of local vessels. The local inflammatory response of vessels exceeded systemic inflammatory response. Intervention of HJD could attenuate inflammatory response, especially in local arteries. Meanwhile, it enhanced systemic anti-inflammatory reactions.

OBJECTIVETo study the effects of Radix Astragali on serum cytokines IL-1beta, TNFalpha and antigen expression of peripheral blood mononuclear cells (PBMCs) in patients with Graves disease (GD).

METHODSEighty GD patients at their first visit were randomly assigned to the methimazole (MMI) group (Group A) and the MMI combined Radix Astragali group (Group B), 40 in each. The improvement of clinical symptoms and thyroid functions were observed after one-month treatment. The serum IL-1beta and TNF-alpha levels in the peripheral blood were determined using radioimmunoassay. The expression levels of surface antigen CD80, CD54, and HLA-DR of PBMCs were detected using flow cytometry.

RESULTSThe improvement of the thyroid gland function was similar in the two groups. There was no obvious change in the levels of autoantibody TGAb or TPOAb of the two groups. Symptoms such as fear of heat, hidrosis, palpitation, and so on were more obviously improved in Group B than in Group A (P < 0.05). The serum IL-betaP, TNFalphaa, CD00 levels in the peripheral blood were all improved in the two groups after treatment when compared with before treatment ( P < 0.05 or P < 0.01). But the serum levels of IL-beta and TNFalpha decreased more obviously in Group B than in Group A ( P < 0.05). The expression of CD54 decreased more obviously in Group B (P < 0.01), showing statistical difference when compared with Group A at the same time point (P < 0.05).

CONCLUSIONRadix Astragali could significantly relieve the clinical symptoms such as hidrosis and palpitation, regulate the immune function of GD patients, playing an important role in the adjuvant therapy for GD.

OBJECTIVETo explore the effects of removing dampness and promoting diuresis method on autoimmune and immuno-inflammatory response caused by nucleus pulposus of rats, in order to provide the basis for the treatment of lumbar disc herniation with Chinese medical immunotherapy.

METHODSForty male Wistar rats were divided into 4 groups randomly according to body weight layer:sham operation group (group A), model contrast group (group B), colchicine tablets group (group C), modified Qingyao decoction group (group D). There were 10 rats in each group. Nucleus pulposus of coccygeal vertebra was transplanted to the gluteal muscle by operation in groups B, C, D, which can lead to autoimmune and immuno-inflammatory response of rats; the rats of group A were only treated with sham operation. At the 3rd day after operation, the rats were fed through intragastric administration, the group A and B with distilled water (10 ml/kg), the group C and D respectively with suspension of colchicine tablets (10 ml/kg, 0.01 mg/ml) and water-decocted liquid of modified Qingyao decoction (10 ml/kg,1.035 g/ml), once a day and continuous medication for 18 days. All rats were killed at the 21th day after operation. The immunoglobulin G (IgG), immunoglobulin M (IgM) and interleukin-1beta (IL-1beta), interleukin-8 (IL-8) level in serum of different groups were detected by ELISA method. At the same time, surrounding tissues of the transplanted nucleus pulposus were observed by pathological section.

RESULTSThe level of IgG, IgM, IL-1beta, IL-8 in serum of group B was significantly higher than that of group A (P < 0.01), while the level of IgG, IgM, IL-1beta, IL-8 in serum of group C, D was significantly lower than that of group B (P < 0.05 or P < 0.01). Moreover, pathological section indicated that immuno-inflammatory response was hardly found in surgical site of group A, while local immuno-inflammatory response of surrounding tissues of the transplanted nucleus pulposus of group C and D was much lighter than that of group B.

CONCLUSIONRemoving dampness and promoting diuresis method could inhibit autoimmune and immuno-inflammatory response caused by nucleus pulposus of rats.

Sparganosis is a tissue invading helminthiasis infecting intermediate hosts, including humans. Strong immune responses are expected to occur in early phases of infection. Thus, we investigated cytokine expressions in splenic dendritic cells and in sera after experimental infection of mice. In splenic dendritic cells, TNF-alpha and IL-1beta expression peaked at week 1 and week 3 post-infection (PI), respectively, and also early phase (week 2 PI) depressed cytokine expression was noticed. Serum IL-1beta concentration increased significantly at week 2 PI and peaked at week 6 PI, and that of TNF-alpha peaked at week 6 PI. These results showed that pro-inflammatory cytokines, TNF-alpha and IL-1beta, are chronologically regulated in mouse sparganosis.

OBJECTIVETo investigate therapeutic effects of balance acupuncture on scapulohumeral periarthritis (SP)and the mechanisms.

METHODSThirty male New Zealand rabbits were randomly divided into a blank group (group B), a model group (group M) and a balance acupuncture group (group BA) with 10 rabbits in each group. SP model was established by using persistent mechanical strain and ice compress. Balance acupuncture at "Jiantong" point was applied in the animals in group BA, but not in the rabbits of the other two groups. Joint movement and pathological changes in tissues around the affected shoulder joint were observed, and interleukin-1beta (IL-1beta), 5-hydroxytryptamine (5-HT) in plasma and the affected surrounding tissues, and DNA contents in tendon of supraspinatus muscle were measured.

RESULTSThe content of plasma 5-HT in group BA [(18.16 +/- 4.44) ng/mL] was significantly lower than that in group M [(23.28 +/- 5.89) ng/mL] (P < 0.05), but without obvious difference in IL-1beta content between the two groups (P > 0.05). Compared with group M, the contents of IL-1beta, 5-HT in affected surrounding tissues, and DNA expression in tendon of supraspinatus muscle were significantly lowered to va rious extent in group BA (P < 0.01, P < 0.05).

CONCLUSIONBalance acupuncture can effectively improve local and systemic pathological situation induced by SP by way of reducing pain-producing factors, inflammatory factors and DNA expression to alleviate local organization and adhesions in rabbits with experimental SP.
