BACKGROUND:The kidney tissues easily affected exercise ischemia reperfusion, increased free radicals and inflammation, resulted in abnormal renal function after acute exercise. OBJECTIVE:To observe the influence of Blackcurrant Extract on the structure of kidney and expression of tumor necrosis factor-α and nuclear factor-κB at 24 hours after exhaustiveexercise. METHODS:A total of 30 male Wistar rats were randomly divided into three groups (n=10). Rats in the Blackcurrant Extract group were intragastricaly administered 0.44 g/kg Blackcurrant Extract. Rats in the quietness control group and 24-hour exhaustive exercise group were intragastricaly given an equal volume of distiled water for 6 consecutive weeks. Rats in the 24-hour exhaustive exercise group and Blackcurrant Extract group received no swimming motion until exhaustion fatigue after final intragastric administration. Twenty-four hours later, samples were obtained. Kidney tissue morphology and ultrastructure were observed by electron microscopy and light microscopy. Protein expression of tumor necrosis factor-α and nuclear factor-κB was detected using immunohistochemistry. Tumor necrosis factor-αmRNA and nuclear factor-κB mRNA expression was detected using RT-PCR. RESULTS AND CONCLUSION:Compared with the quietness control group, tumor necrosis factor-α protein and nuclear factor-κB protein expression in the kidney was higher in the 24-hour exhaustive exercise group, and tumor necrosis factor-α mRNA and nuclear factor-κB mRNA expression was significantly increased (P < 0.01). Compared with the 24-hour exhaustive exercise group, tumor necrosis factor-α protein and nuclear factor-κB protein expression was lower in the Blackcurrant Extract group, and nuclear factor-κB mRNA expression was significantly decreased (P < 0.05); tumor necrosis factor-α mRNA expression was significantly reduced (P < 0.01). Kidney in the 24-hour exhaustive exercise group showed obvious morphological changes and ultrastructural damage. The structure of the kidney in the Blackcurrant Extract group tended to be normal. Results suggested that Blackcurrant Extract can repair the kidney tissue injury, reduce the expression of inflammatory factors, and prevent inflammatory damage in the kidney at 24 hours after exhaustive exercise.

cholesterol 7α-hydroxylase gene ( CYP7A 1 ) plays a key role in the catabolism of cholesterol into bile acids. To investigate whether the A-204C polymorphism in CYP7A1 gene affects the gene expression,using luciferase as the reporter gene, four recombinants were constructed by inserting forward or reverse sequence with A or C allele at the polymorphism site into the promoter-less vector pGL3-basic. The constructs were then transfected into four cell lines and the luciferase activity of each expression vector was examined by dual luciferase reporter gene assay system. The results showed that activities of the forward sequence of both genotypes were higher than that of reverse sequence. Promoter activity of the recombinants with A allele was about one third lower than that with C allele. According to the analysis with TRANSFAC database, there may exist a Zic3 binding site when there is the C allele at -204. Our study indicates that the A-204 C polymorphism in CYP7A1 promoter region decreases its promoter activity and thus represses the gene expression, possibly due to the lack of a potential Zic3 binding site.

BACKGROUND:Urine-derived stem cels are most likely to come from the kidney tissue, and therefore, these cels are more adaptable to kidney microenvironment, providing a new option for the treatment of kidney diseases.
OBJECTIVE: To explore the therapeutic efficacy of human urine-derived stem cels on chronic nephropathy rats.
METHODS:The fresh urine samples of healthy people were colected, and then human urine-derived stem cels were extracted and cultured in vitro. Twenty Sprague-Dawley rats were used to prepare chronic nephropathy models, and given injection of human urine-derived stem cel suspension (experimental) or normal saline (control) into the renal cortex, respectively. Another 10 healthy rats were used as controls. Therapeutic effects on renal function were assessed by detection of serum creatinine level and glomerular filtration rate in the three groups. The kidney tissues of rats were taken and observed histomorphologicaly in each group.
RESULTS AND CONCLUSION: Human urine-derived stem cels were found to remarkable improve rat’s renal function as wel as reduce the histomorphological changes in the kidney tissues of rats. Compared with the control group, the serum creatinine level was decreased while the glomerular filtration rate was increased significantly in the experimental group; CD68 expression and infiltration of interstitial inflammatory cels were also markedly reduced in the experimental group. To conclude, human urine-derived stem cels can improve the renal function of chronic nephropathy rats.

Objective To study if IRF1 could regulate the polarization by IRF 1 and M1 status and affect M1 media-ted antitumor function .Methods U937 derived M1 macrophage ( U937-M1 ) model was established .The cells were devided into 4 groups:the PMA pretreated unpolarized macrophage (M0), the PMA, IFN-γand LPS induced M1 macrophage (M1), the siRNA of IRF1 knocked down M1 macrophage (siIRF1) and the negative control siR-NA treated M1 macrophage (siC).Furthermore, the expression of CD86 and CD206 was detected by flow cytome-try, the M1/M2 associated markers (IL-12p35,IL-12p40,IL-23p19,IL-6,TNF-α/IL-10) and IFNB1 were ana-lyzed by qPCR,the expression of IL-12p70 and IL-10 was examined by ELISA, the expression of IRF1 and IRF5 was detected by Western blot , the proliferration and apoptosis of HCC were analyzed by CCK 8 and flow cytometry , respectively.Results Compared with the U937-M1, the IRF1 knocked down group showed impaired CD 86 expres-sion, but enhanced CD206 expreesion ( P<0.05 ); the expression of M1 related cytokines including IL-12p35, IL-12p40,IL-23p19,IL-6,TNF-αand IFNB1 was decreased, but M2 related cytokine IL-10 level was increased (P<0.01);the expression of IFN-β, IL-12p70 and IRF5 was impaired, but IL-10 was enhanced (P<0.05).In IRF1 knocked down U937-M1, the CCK8 analysis indicated that the M1 mediated anti-proliferation effects on hepatoma carcinoma cell were turned to pro-proliferation ( P<0.05);the flow cytometry showed that the M 1 mediated pro-ap-optosis effects were reversed to anti-apoptosis ( P<0.01 ) .Interestingly , IRF5 and IFN-βwere decreased at both mRNA and protein levels in IRF1 knocked down U937-M1 compared with the U937-M1 (P<0.01).Conclusions IRF1 may partly modulate IRF5 and IFN-β, and further regulate M1 polarization and its antitumor effects .

Toutongling Capsule is a Chinese herbal preparation developing from an ancient formula processed by modern technology. Previous clinical studies have shown that Toutongling Capsule exerts a good effect on vascular headache, tonic headache and traumatic headache. To further explore its pharmacological mechanism, the effect of Toutongling Capsule on cerebral vessels and blood viscosity in experimental dogs was observed. The results showed that Toutongling Capsule can decrease cerebral vascular resistance obviously and increase cerebral blood flow, with a good dose-effect relationship. As compared with Yangjiao Granule, Toutongling Capsule possesses a similar effect on blood viscosity but stronger effect on dilatation of cerebral vessels and increase of cerebral blood flow. Both Toutongling Capsule and Yangjiao Granule have no effect on blood pressure and ECG.

ObjectiveTo evaluate the effect of alpha-lipoic acid (ALA) on cardiomyocyte apoptosis following renal ischemia-reperfusion injury(RIRI) in rats.MethodsThirty-six male SD rats weighing 250-280 g were randomly divided into 3 groups ( n =12 each): group sham operation (group S) ; group I/R and group I/R + ALA ( group L).The model of RIRI was produced by occlusion of renal artery and vein for 45 min followed by 24 h reperfusion,in group S the renal pedicles were exposed but not occluded.In group L ALA infusion (30 mg/kg) was given via tail vein at 20 mln before ischemia and at 20 min before reperfusion,while in group I/R the equal volume of solution (35％ polyethylene glycol + 60％ physiological saline + 5％ ethanol) was infused instead of ALA.The animals were saerificed at the end of 24 h of reperfusion,blood samples were taken for detecting concentrations of serum creatinine (Cr) and malondialdehyde (MDA).Then the hearts were immediately removed for determination of SOD activity,MDA content,cardiomyocyte apoptosis (flow cytometry) and Bcl-2/Bax ratio (immunohistology).ResultsSerum Cr concentration,serum and myocardium MDA levels and cardiomyocyte apoptosis were significantly increased after RIRI in groups I/R and L as compared with group S ( P ＜ 0.05).ALA treatment significantly decreased serum Cr concentration,serum and myocardium MDA levels,cardiomyocyte apoptosis and increased SOD activity and Bcl-2/Bax ratio ( P ＜ 0.05).ConclusionALA can attenuate myocardium injury by inhibiting cardiomyocyte apoptosis following RIRI in rats.
