ABSTRACT
Objective An analysis was carried out for the reports of traditional Chinese medical syndrome patterns of psoriatic arthritis (PsA) patients in related reports issued in the recent 35 years, thus to explore the characteristics of syndrome patterns of PsA patients and to supply evidence for the syndrome classification. Methods Electronic retrieval was performed in the reports of PsA syndrome analysis issued in the Chinese medical journals from the year of 1979 to 2013. Traditional Chinese medical syndrome information of PsA patients was extracted from the reports, and then was standardized and classified. SPSS 17.0 software was applied for the analysis of occurrence frequency of syndromes, syndrome elements, tongue and pulse states. Results A total of 84 reports were obtained, and 26 reports met the inclusion criteria. In the 26 included reports, 10 kinds of tongue texture, 15 kinds of tongue fur and 22 kinds of pulse states were present. After the standardization of the syndromes, a total of 39 syndrome patterns were obtained. After combination of the similar syndromes, 14 syndromes were included into the analysis. In the 14 included syndrome patterns, the leading 5 patterns were wind-damp heat arthralgia, wind-heat with blood dryness, excessive heat toxin, wind-cold damp arthralgia, and liver-kidney deficiency. Fourteen syndrome elements were extracted from the syndromes, and 9 were included into the analysis after combination of the similar syndrome elements. The top syndrome elements were heat, phlegm-dampness, wind, dryness, deficiency, and blood stasis. Conclusion The syndrome patterns of PsA patients are various, and the syndrome elements of cold, heat, phlegm-dampness, wind, dryness, and blood stasis play an important role in the pathogenesis of PsA.
ABSTRACT
AIM:To examine the effects of thromboxane A 2 receptor ( TXA2 R) , the downstream product of cy-clooxygenase-2 (COX-2), on the proliferative ability and COX-2 expression in rheumatoid arthritis (RA) synovial cells. METHODS:The effects of TXA2 R antagonist SQ29548 and agonist U46619 on the proliferation of RA synovial cell line MH7A were detected by MTS cell proliferation assay , and their effects on COX-2 mRNA expression in MH7A cells were al-so examined by real-time PCR.In addition, the possible effect of U46619 on the proliferation of MH7A cells, when COX-2 was knocked down by siRNA , was determined by BrdU cell proliferation assay .RESULTS:SQ29548 inhibited the cell proliferation and the mRNA level of COX-2 while U46619 enhanced them.Moreover, U46619 reconstitute the proliferative ability of MH7A cells to some extent that inhibited by COX-2 siRNA.CONCLUSION: In RA synovial cells, TXA2R is able to control COX-2 expression, while it also mediates the effects of COX-2, suggesting that TXA2R might be an ideal candidate for RA treatment .
ABSTRACT
Objective To study effect of Tongbiling (TBL) on VEGF mRNA expression in RA synovlcytes cultured in vitro and explore its mechanism. Method Synovial cells from the knee joint in patient with RA were digested, divided and separately cultured after arthroscopy. Blank controls:DMEM culture containing 10% FBS in saline;Low-dose admission group of TBL:DMEM culture containing 10% FBS in 50 mg/L TBL;High-dose admission of TBL:DMEM culture containing 10% FBS in 200 mg/L TBL. RNA were distilled. Expression of VEGF mRNA were detected with RT-PCR. Result Compared with control group, expression of VEGF mRNA in low and high-dose admission groups of TBL both decreased (P
