ABSTRACT
ObjectiveToclarifytheprotectiveactionofaChinesemedicine,Jie-Du-Qu-Yu-Zi-Shen prescription, on the lupus nephritis in MRL/lpr mice through the TLR9-MyD88-NF-κB signaling pathway .Methods Thirty MRL/lpr mice were randomly divided into model group , prednisone group , and traditional Chinese medicine ( TCM) group (n=10).Each treatment group received appropriate treatment or drug therapy for 8 weeks.The pathological changes of mouse renal tissues in the three groups were examined and compared using HE , PAS, and Masson staining .Real-time PCR was performed to compare the expression of TLR-9, MyD88, NF-κBm RNA mRNA in each group of the mice . Results Compared with the model group , the Chinese medicine Jie-Du-Qu-Yu-Zi-Shen prescription significantly improved the renal pathological tissue damages in the MRL/lpr mice.Real-time PCR assay showed that the expression levels of TLR-9, MyD88, NF-κB mRNA in the TCM group were significantly lowered (P0.05 ) .Conclusions Jie-Du-Qu-Yu-Zi-Shen prescription has protective effect on the kidney of MRL /lpr mice, alleviating its pathological changes , and delaying the disease course, probably, through inhibiting the TLR-9-MyD88-NF-κB signaling pathway in the kidneys of MRL/lpr mice.
ABSTRACT
Objective To explore the effects of Jiedu Quyu Ziyin Recipe (JQZR) on the apoptosis and expressions of bcl-2 and bax mRNA of peripheral-blood lymphocyte in MRL/lpr mice. Methods 80 MRL/lpr mice were randomly divided into model group,TCM group, Western medicine group and TCM and Western medicine group,20 mice in each group, meanwhile,20 Kunming mice were selected as normal group, then intragastrically administered normal sodium, JQZR apozem, prednisone suspension and JQZR apozem and prednisone suspension, 0. 5ml every time,once daily for 12 weeks respectively. At the end of the 12th week, peripheral-blood lymphocytes of every mice purified by gradient centrifugation were cultivated for 48 hours ,then the apoptosis was detected by flow cytometry. Furthermore,the expressions of bcl-2 and bax mRNA of peripheral-blood lymphocyte were detected by RT-PCR. Results At Oh or 48h,the apoptosis ratios of PBLC in normal group, TCM group,Western medicine group and TCM and Western medicine group are higher than model group and the differences are significant(P <0. 05 ,P <0. 01 ) ,while,at Oh,which are not significant within Western medicine group, normal group and TCM and Western medicine group ( P > 0. 05) ,even if which are significant between TCM group and TCM and Western medicine group or between model group and TCM and Western medicine group( P < 0. 05 ). At 48h, the differences of apoptosis ratios of PBLC are significant between Western medicine group and TCM and Western medicine group( P < 0. 05 ), and between TCM group and TCM and Western medicine group or between model group and TCM and Western medicine group which are significant, too( P < 0. 01 ). The ratios of bcl-2/bax mRNA of normal group,TCM group and TCM and Western medicine group are significantly lower than which of model group or Western medicine group ( P < 0. 05, P < 0. 05, P <0. 01 ,respectively) ,but there is no significant difference between which of model group and Western medicine group.Conclusion JQZR has adjustable effects on the apoptosis and expressions of bcl-2 and bax mRNA of peripheralblood lymphocyte in MRL/lpr Mice.
ABSTRACT
By analyzing 《Shang Han Lun》,《Jin Kui Yao lue》records about diaphoresis,Zhong Jing's method of diaphoresis was generalized in adaptation disease,contraindication,regulation and combination with other methods.The aim is to use the method of diaphoresis well clinically.
ABSTRACT
By analyzing Gualou Qumai Wan-related content in Jingui Yao Le,to explore the indication of Gualou Qumai Wan. The conclusion showed that Gualou Qumai Wan was applicable to the syndrome of yang deficiency and moist-heat injuring yin of lower jiao. The conclusion was verified by the author's clinical experiences aiming to broaden clinical use of Gualou Qumai Wan.
