ABSTRACT
[Objective] To systematically study the characteristics of the key syndromes of systemic lupus erythematosus(SLE),summarize its clinical efficacy,and explore the mechanism of traditional Chinese medicine(TCM).[Methods] The main clinical syndrome features of SLE are heat-toxicity,blood stasis and Yin-deficiency.Compared with glucocorticoids(GCs) alone,combination with JP can significantly improve the clinical efficacy and reduce the glucocorticoid treat consumption effectively.[Results]Our results showed that in MRL/LPR model mice,JP could restore the balance between TH17 and regulatory T cells through CaMK4 signaling pathway,and the interaction between T cells and B cells.JP could promote DNA methylation,inhibit the over-activated lymphocytes,improve the prognosis of SLE and prevent renal damage.JP could up-regulate the concentration of eicosapentaenoic acid (EPA) and the level of glycine,phenylalanine and tryptophan dramatically.Furthermore,JP could reduce the abundance of pathogenic bacteria(such as Parabacteroides) and increase the abundance of beneficial bacteria (such as Odoribacter and Ruminococcus) by regulating gastrointestinal function,which was not found in GCs treated subjects.JP can also obviously reduce the expression of TLR7,TLR9 and IL-6 in intestinal mucosa,showing the effect of multi-target therapy on SLE.[Conclusion] The most common clinical syndromes of SLE are heat-toxicity,blood stasis and Yin-deficiency.JP can effectively control the progress of SLE and exert its clinical function from different aspects.Our research laid the scientific basis for the popularization and application of TCM in clinical treatment of SLE.
ABSTRACT
Objective To study the effects of Jiedu Quyu Ziyin Prescription (JQZP)-treated freeze dried powder and drug-containing serum on the inflammatory signal pathway of monocyte-macrophage induced by LPS (lipopolysaccharide) in mice. Methods Monocyte-macrophage cells were cultured in vitro and randomly divided into blank group, LPS stimulation group, drug-containing serum group, freeze dried powder group, LPS + drug-containing serum group, and LPS + freeze dried powder group. After 24 h intervention, the optimal concentrations of drug-containing serum and freeze dried powder were screened by CCK8 method and the cell viability was measured respectively. The content of tumor necrosis factor (TNF-α) in cell serum was measured by ELISA. Real-time PCR was employed to test the expression of TNF-α mRNA and nuclear transcription factor kappa-light-chain-enhancer of activated B cells (NF-κB). Western-blot was used to detect the expression of NF-κB protein. The LC-MS was used to detect the active ingredients in the drug-containing serum. Results Compared with the blank group, the expression of TNF-α level, NF-κB, TNF-α mRNA and NF-κB protein in LPS stimulation group were significantly increased (P < 0.05). Compared with the LPS stimulation group, the TNF-α level, NF-κB, TNF-α mRNA and the expression of NF-κB protein in the LPS plus serum group were significantly lower than those in the LPS plus freeze-dried powder group (P < 0.05). Paeoniflorin and ferulic acid were detected in the drug-containing serum. Conclusion JQZP freeze-dried powder and drug-containing serum all have the effect of inhibiting the inflammatory signaling pathway.
