Effects of Tryptergium Wilfordii Polyglyco-Sidium on the Interleukin 1 Levels in Aqueous Humor after Intraocular Lens Implantition

Several studies have suggested that recombinant human IL-1a was injected into the vitreous of rabbits,and an iridocyclitis was observed.We have reported an experimental study of IL-1 levels in aqueous humor after intraocular lens (IOL) implantation.Effects of tryptergium wilfordii polyglyco-sidium(TWP)on the IL-1 levels in aqueous humor after IOL implantation were studied in the rabbits in this paper.     

Effects of Bushen Zhuanggu Formul on interleukin-6 production and bone metabolism of the ovariectomized rats

Objective： To observe the effects of Bushen Zhuanggu Formul on intedeukin 6 （IL-6） level and bone metabolism of the ovariectomized rats, and to explore the possible mechanism of preventing and treating postmenopausal osteo porosis by traditional Chinese Formul. Methods： SD rats were randomly divided into 4 groups： normal control group （N）, ovariectomized control group （OVX）, estrogen-treated group （OVX＋E） traditional and Chinese medicine-treated group （OVX＋ CM）. After treaanent, IL-6 levels in rat bone tissue media and serum were examined by ELISA. The proximal tibias（PTM） of rats were undecalcified for quantitative bone histomorphometry. Results： Compared with OVX group, both Bushen Zhuanggu medicine and estrogen decreased IL-6 level in rat bone tissue media. However, the effects of Bushen Zhuanggu Formul were weaker than those of estrogen. Furthermore, Bushen Zhuanggu Formul and estrogen produced a reduction in bone turnover by inhibiting bone formation and bone resorption at the same time. Conclusion： Bushen Zhuanggu Formul prevents ovariectomic bone loss by inhibiting IL-6 production in rat bone tissues.     

Interleukin-6 alters the cellular responsiveness to clopidogrel, irinotecan, and Oseltamivir by suppressing the expression of Carboxylesterases HCE1 and HCE2

Carboxylesterases constitute a class of enzymes that play important roles in the hydrolytic metabolism of drugs and other xenobiotics, patients with liver conditions such as cirrhosis show increased secretion of proinflammatory cytokines [e. g., interleukin-6 （IL- 6）] and decreased capacity of hydrolysis. In this sfudy, we provide a molecular explanation linking cytokine secretion directly to the decreased capacity of hydrolytic biotransformation. In both primary hepatocytes and HepG2 cells, treatment with IL-6 decreased the expression of human carboxylesterases HCE1 and HCE2 by as much as 60%. The decreased expression occurred at both mRNA and protein levels, and it was confirmed .by enzymatic assay. In cotransfection experiments, both HCE1 and HCE2 promoters were significantly repressed, and the repression was comparable with the decrease in HCE1 and HCE2 mRNA, suggesting that transrepression is responsible for the suppressed expression. In addition, pretreatment with IL-6 altered the cellular responsiveness in an opposite manner of overexpression of HCE1 and HCE2 toward various ester therapeutic agents （ e. g., clopidogrel）. Transfection of HCE1, for example, decreased the cytotoxicity induced by antithrombogenic agent clopidogrel, whereas pretreatment with IL-6 increased the cytotoxicity. Such a reversal was observed with other ester drugs, including anticancer agent irinotecan and anti-influenza agent oseltamivir. The altered cellular responsiveness was observed when drugs were assayed at sub-and low-micromolar concentrations, suggesting that suppressed expression of carboxylesterases by IL-6 has profound pharmacological consequences, particularly with those that are hvdrolvzed in an isoform-specific manner.     

Effect of Xuezhikang Capsule(血脂康胶囊)on Serum Tumor Necrosis Factor-αand Interleukin-6 in Patients with Nonalcoholic Fatty Liver Disease and Hyperlipidemia

<正>Objective:To evaluate the effect of Xuezhikang Capsule(血脂康胶囊) on the serum levels of inflammatory factors such as tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) in patients with nonalcoholic fatty liver disease(NAFLD) and hyperlipidemia,and to explore whether it has anti-inflammatory effect.Methods:A total of 84 patients were randomly assigned to two groups with stratified block randomization, the treatment group(42 cases) and the control group(42 cases).They were treated with Xuezhikang Capsule and polyene phosphatidylcholine capsule for twenty-four weeks,respectively.The changes in serum TNF-αand IL-6 were measured by enzyme linked immunosorbent assay before treatment and at the 12th and 24th week. Results:Compared with those before treatment,the serum levels of TNF-αand IL-6 significantly decreased in both groups after treatment(P0.01).There was no significant change between the two groups for the treatments at different time points(P0.05) and between the two groups for treatments at the same time points (P0.05).Conclusion:Xuezhikang Capsule can inhibit the serum inflammatory factor in patients with NAFLD and hyperlipidemia.
