Objective To study the effect of p50 on IKKα at IL-1β promoter in LPS tolerant cells and to reveal the mechanism of the inhibition of IL-1β mRNA by pS0. Methods THP-1 human promono-cyte model of endotoxin tolerance that simulates the sepsis leukocyte phenotype was used. Chromatin immu-noprecipitation assay(CHIP) and real-time PCR were applied to quantify the binding of p50 and IKKα to IL-1βpromoter. IL-1β mRNA transcription was studied after knocking-down of p50 and/or IKKα. Results With LPS stimulation, p50 binding did not reduce but somewhat increased at IL-1β promoter in tolerant THP-1 cells. Knocking-down of p50 increased the transcription of IL-1β mRNA, which revealed the inhibi-tory effect of p50 in tolerant cells. In contrast, the accumulation of IKKα to IL-1β promoter decreased with LPS stimulation in tolerant cells; However, IKKα binding increased after p50 gene knock-down. In the meantime, IL-1β mRNA transcription increased; At last, IL-1β mRNA decreased again after double-knoc-king down of p50 and IKKα. Conclusion p50 is an inhibitory protein at IL-1β promoter in tolerant THP-1 cells. The unresponsiveness of IL-1β mRNA transcription to LPS at least partly results from the inhibition of IKKα binding to IL-1β promoter by p50.

OBJECTIVE:To study the inhibition effects of tranilast on hypertrophic scar tissue of rabbits and its mechanism. METHODS:Rabbits were selected to induce hypertrophic scar(HS)model,the HS model rats were randomly divided into model control group (normal saline),tranilast low-dose,medium-dose,high-dose groups (0.3,0.5,0.7 mg/kg),6 rabbits in each group,local intradermaly injected corresponding drugs. Scar thickness 1 h before injection and the first,third,fifth week after in-jection in each group were measured,pathological changes of scar(fifth week after injection)were observed,transforming growth factor β1 (TGF-β1),α-smooth muscle actin(α-SMA)mRNA and protein expression were detected. RESULTS:Compared with 1 h before injection,scar thickness of rabbits in other groups were decreased after injection except for model control group. In fifth week after injection,compared with model control group,scar thickness of rabbits in other groups were decreased,pathological changes were improved;TGF-β1,α-SMA mRNA and protein expression were decreased (P<0.05),showing positive correlation with tranilast dose. CONCLUSIONS:Tranilast can inhibit the formation of hypertrophic scar,and the mechanism may be related to inhibiting the TGF-β1,α-SMA mRNA and protein expression.

Nitrogen removal techniques based on Anammox process are developing rapidly these years. The distribution and diversity of Anammox have become important research directions. A variety of Anammox have been detected till now, of which only Kuenenia and Brocadia are often detected in wastewater treatment systems. In addition, in a single niche there is only one type of Anammox bacteria. However, the distribution mechanism and transformation of Anammox bacteria in different niches are still ambiguous. Therefore, the distribution of Anammox in various conditions was summarized and analyzed in this article. And the key factors influencing the distribution of Anammox were concluded, including substrate concentration and the specific growth rate, sludge properties and microbial niche, the joint action and influence of multiple factors. The engineering significance research on the distribution and influencing factors of Anammox bacteria in the sewage system and proposed research prospects were expounded.
