ABSTRACT
Objective To observe the effect of sinomenine(SINO) on immune function of adjuvant arthritis(AA) rats.Methods SD rats were randomized into normal group,model group,SINO groups(treated with gastric gavage of SINO at the doses of 60,120 and 240 mg/kg respectively),and glucosides of Tripterygium Wilfordii(30 mg/kg) group.Except the normal group,the rats in other groups received subcutaneous injection of the complete Freund's adjuvant 0.1mL into the left hind foot to induce AA.The medication began from 12 days after the modeling and lasted 12 days.The pedal swelling and joint function scores were observed in different time.Radioimmunoassay was used to detect the contents of interleukin-1?(IL-1?) and tumor necrosis factor ?(TNF-?) in synovial cells.Expression of IL-1? and TNF-? mRNA was examined by reverse transcription-polymerase chain reaction(RT-PCR) assay.Results SINO at different concentrations decreased the pedal swelling and arthritis scores to various degrees,inhibited the production of IL-1? and TNF-? in the synovial cells,reduced the expression of IL-1? and TNF-? mRNA,and recovered the normal histological features of synovial cells in AA rats.Conclusion The therapeutic mechanism of SINO for rheumatoid arthritis may be related with the inhibition of secretion of inflammatory mediators in synovial cells,and with the recovery of histological features of synovial cells.
ABSTRACT
[Objective] To investigate the synergistic action of fuming-washing therapy with Qingbixifang ( a herbal lotion mainly composed of Herba Siegesbeckiae, Cortex Phellodendri, Radix Paeoniae Rubra, Radix Rehmanniae, Radix Stephaniae Tetrandrae, Rhizoma Atractylodis, Herba Ecliptae, Nidus Vespae, Olibanum, Myrrha, etc.) on rheumatoid arthritis (RA) with heat retention. [Methods] Sixty patients of RA with heat retention were randomized into groups A and B. Group A ( n = 30) was treated by fuming and washing the affected part with Qingbixifang, and taking Tongbiling Tablets and nimesulide; group B (n = 30) was treated by taking Tongbiling Tablets and nimesulide only. The treatment course of the two groups lasted one month. The time of morning stiffness, grip strength, the number of joints with tenderness, tenderness index, resting pain in joints, the number of swelling joints, swelling index, evaluation by patients themselves and by the doctor were compared before and after treatment. Laboratory parameters such as blood rheumatoid factor (RF), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell (WBC) count and platelet (PLT) count were also observed before and after treatment. [Results] The total effective rate was 90.0% in group A and 66.7% in group B, the difference being significant (P
ABSTRACT
[Objective] To evaluate the therapeutic effect of Chinese herbal medicine of Yishen Zhuanggu Tongbi Decoction (YZTD), a formula mainly composed of Radix Aconiti Lateralis Preparata, Hema Epimedii, Fructus Psoraleae,Rhizoma Chuanxiong, Radix Angelicae Sinensis, Radix Angelicae Pubescentis and Radix Dipsaci, for rheumatoid arthritis (RA). [Methods] Forty-four cases of RA were randomized into two groups: group A ( n = 24) was treated with YZTD for oral use and with the residue of YZTD for external application; group B ( n = 20) was treated with diclofenac sodium. After 8-week treatment, function of joint, adverse reactions, erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), C-reactive protein (CRP) and immunoglobulins levels were observed. Continuous treatment was given for the effective cases and a follow-up was conducted for 1 - 3 years to observe its long-term effect. [ Results ] Pain, swelling, tenderness and morning rigidity of the joints were improved much more in group A than those in group B ( P
ABSTRACT
[ObjectivejTo explore the therapeutic mechanism of Tongbiling (TBL) prescription for rheumatoid arthritis (RA) by observing the effects of TBL on inflammation and expression of vascular endothelial growth factor (VEGF) in synovium of rats with collagen-induced arthritis (CIA) .[Methods]CIA rat models were established by subcutaneous injection of type II collagen. Pathological sections of synovium in knee joint were made after medication for 37 days and then stained by HE method and immunohistochemical method respectively. Infiltration of inflammatory cells and hyperplasia of macrophages A and fibrous tissue in HE-stained pathological sections were observed under microscope and expression of VEGF was observed by semi-quantitative immunohistochemical method. [ Results ] Infiltration of inflammatory cells and hyperplasia of macrophages A and fibrous tissue in high-dose TBL group were inferior to those in model group (P 0.05); both TBL and Radix Tripterygii Wilfordii at high dose decreased the expression of VEGF (P
ABSTRACT
[Objective] To observe the effects of Tongbiling (TBL) prescription in counteracting cartilage destruction in rats with rheumatoid arthritis (RA). [Methods] Collagen-induced arthritis (CIA) rat models were established to observe the therapeutic effects of TBL. After a short-term treatment, expressions of tumor necrosis factor (TNF - a) and transforming growth factor (TGF- P) in cartilage tissue of model group, methotrenxate (MTX) tablets group and Radix Tripterygii Wilfordii (RTW) preparation group were examined by immunohistochemical semi-quantitative assessment method. [ Results ] The number of chondrocytes with positive TNF - a expression was lower and the chondrocytes were stained lighter in normal group than those in model group and low-dose MTX group ( P
ABSTRACT
[Objective] To investigate the effect of Erteng Mixture (EM) on activated T-cell CD69 expression and Jurkat cell cycle in rheumatoid arthritis (RA) and to explore its possible cellular immunoregulation mechanism. [Methods] Jurkat cells were cultured with different kinds of components extracted from EM. After 72 hours, proliferation rate of Jurkat cell were detected with thiazolyl blue colorimetry (MTT) to screen the active component. Whole blood from RA patients were incubated in RPMI-1640 culture with various concentrations of chlorofonn component extracted from EM or with Genistein. Thirty minutes later, phytahematoagglutinin (PHA) were added successively into the culture. After 24 hours, CD69 expression rate of T lymphocytes activated by PHA was analyzed by flow cytometry. Jurkat cells were cultured with various concentrations of chloroform component extracted from EM and with methotrexate ( MIX) for 48 hours. After then, Jurkat cell cycle was analyzed by flow cytometry. [ Results ] Chloroform component extracted from EM had the strongest inhibitive effect on proliferation of Jurkat cells. Chloroform component (10 mg/L and 20 mg/L) could markedly inhibit CD69 expression on PHA-activated T lymphocytes. Chloroform component 10 mg/L blocked Jurkat cell cycle at G1 phase, which differed from MTX blocking Jurkat cell cycle at S phase. [Conclusion] Chloroform component extracted from EM could significantly inhibit the early activation of CD4 T lymphocytes in RA and inhibit the energy and material synthesis in T-cell, thus hindering DNA synthesis and decreasing the cellular G2 phase transformation. This study will provide an experimental basis for clinical application of EM in treating RA.
