ABSTRACT

In recent years,the incidence of hand foot and mouth disease has been on the rise with severe and fatal cases often caused by enterovirus 71(EV71) infection. EV71 possesses powerful ability of neural inva-sion,and severe nerve damage is one of the signs of its infection,including aseptic meningitis,poliomyelitis-like paralysis,acute brainstem encephalitis and other severe neurological syndrome,which may make the neurological sequelae difficult to reverse,and even death. At present,EV71 has become one of the main viral pathogens cau-sing central nervous system diseases in infants and young children,which seriously threatens the life and health of infants and young children. The pathogenesis of EV71 has not yet been totally clarified. Clinically,it mainly focuses on symptomatic supportive care and prevention of complications. This article starts with the introduction of the etiology of EV71 and briefly describes its relative pathogenesis with the view of providing new ideas for its intervention at the level of primary prevention.

ABSTRACT

Objectives To investigate the effect of matrine (MAT) on adriamycin (ADR) induced podocyte injury in vitro and explore the function of the mammalian target of rapamycin (mTOR) protein signaling pathway during the intervention. Methods ADR (1μmol/L) was used to induce the model of podocyte injury and then the podocytes were intervened by 10, 20 and 40μg/ml MAT for 24 hours. The viability and apoptosis rate of podocytes, mRNA and protein expressions of desmin and mTOR were detected. The effect of different concentrations of MAT on ADR-induced podocytes was analyzed. Results Com-pared with the control group, declined viability of podocytes (P<0.001), increased percentage of apoptotic podocytes (P<0.001), and increased expression of damage marker desmin (P=0.002) were observed in ADR group. In ADR group, after intervention with MAT of 10-40μg/ml, increased viability of podocytes (P<0.05), decreased percentage of apoptotic podocytes (P<0.05), and decreased expression of damage marker Desmin were found (P<0.05). The protein expression of mTOR and phosphorylation state of mTOR (p-mTOR) decreased in ADR induced-podocytes (P<0.05), and after intervention with MAT of 10-40μg/ml, the expression of mTOR and p-mTOR increased (P<0.05). The expression of mTOR downstream target protein s6k1 and 4EBP1 mRNA decreased in ADR group (P=0.071), while increased after intervention with MAT of 10-40μg/ml (P<0.05). Conclusions 10-40μg/ml MAT have protective effects on ADR-induced podocytes in vitro. The protection mechanism may be related to mTOR signaling pathway.

ABSTRACT

Objectives To determine the effects of Matrine (Ma) on signal transducers and activators of transcription (STAT) 1, 3, connective tissue growth factor (CTGF) and platelet -derived growth factor (PDGF) in glomerular mesangial cells (MC) induced by lipopolysaccharide (LPS), and to explore the protective mechanisms of Ma. Methods Ma were added to cultured glomerular mesangial cells which were exposed to LPS for 12, 24 and 48 hours. Real time polymerase chain reaction were used to determine STAT1, 3, CTGF, PDGF mRNA, The protein expression of STATI, 3 and p-STAT1, 3 were observed by Western blot. Results Compared with the control group, MC proliferation of the LPS group (10μg/ml) significantly increased, which were suppressed in the Ma (320 μg/ml) group (P < 0.01) at 12, 24, 48 hours. The expression of STAT1, 3, CTGF, PDGF mRNA and the levels of p-STAT1 , p-STAT3 protein was significantly increased in MC under LPS medium at 12, 24, 48 hours, which were obviously lower in Ma group than those of the LPS group, especially at 24, 48 hours. Conclusions The protective mechanisms of Matrine is considered to down-regulate the expression of STAT1, 3, CTGF and PDGF.

ABSTRACT

Objective To study the effect of oxymatrine on p-STAT3 and PIAS3 signaling molecule and it's mRNA expression in the proliferation of the human mesangial cells (HMCs) induced by lipopolysaccharide(LPS) and to explore their relationship. Methods HMCs were divided into three groups: control group, LPS group and oxymatrine group. HMC proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay. Type Ⅳ collagen in the supernatants of the cultured HMCs was detected by ELISA at 12, 24, 48 hours respectively. At the same time, the protein and mRNA expressions of p-STAT3 and PIAS3 were measured by Western blot and real-time quantitative RT-PCR. Results The cell proliferation, the mRNA and protein expression of type Ⅳ collagen, p-STAT3 in LPS group were increased compared with the control group (P<0.01), but they were decreased in oxymatrine group (P < 0.01). The expressions of protein and mRNA of PIAS3 in LPS group were decreased significantly compared with control group (P<0.01), but they were increased in oxymatrine group (P<0.01). Conclusion Oxymatrine can down-regulate the expression of p-STAT3 and up-regulate the expression of PIAS3, which plays an important role in the process of LPS-induced HMCs proliferation.
