Objective To explore the regulatory effect of TAK 1 inhibitors on MAPK and NF-κB signaling pathway in diabetic rats and its renal protection mechanism .Methods A total of 48 rats accorded to the random number table method were divided into DN group , TAK1 group and control group ,each group with 16 rats,control group with normal fed , DN group and TAK1 group by the intraperitoneal injection of 1%50 mg/kg STZ DN model rat.8 rats were killed in each group at 4 weeks and 8 weeks respectively ,the pathological changes of renal tissue were observed ,serum TNF-α,MCP-1,IL-1βlevels were detected by enzyme linked immunosorbent assay ,p38MAPK,NF-κBp63 protein expression were detected by Western blotting ,p38MAPK、NF-κBp63 mRNA levels in renal tissue were detected by real time fluorescence quantitative PCR.Results At 4 weeks and 8 weeks, the body weight, blood glucose and UAER of DN group and TAKl group were significantly higher than those in control group (P <0.05).The body weight and UAER of DN group were significantly higher than those of TAK1 group (P <0.05).The serum TNF-α,MCP-1,IL-1βlevels in DN group and TAK1 group were significantly higher than those in control group (P <0.05),and DN group serum TNF-α,MCP-1,IL-1βlevels were significantly higher than those in TAK1 group (P <0.05).The expression levels of p38MAPK,NF-κBp63 protein and mRNA in DN group, TAK1 group were significantly higher than those in control group (P <0.05), and p38MAPK,NF-κBp63 protein and mRNA in DN group was significantly higher than that in TAK 1 group ( P <0.05 ) .Conclusions TAK1 induces inflammation by activating MAPK and NF-κB signaling pathways,and participates in diabetic renal injury . TAK1 inhibitors with anti-inflammatory effect by down regulate the expression of inflammatory factors .

Objective Based on the different physiological characteristics of the mastoid skin and soft tissue in congenital microtia malformation ,the different ear reconstructivemethod were respectively applied for the individuals with microtia .And the feasibility of personalized treatment to microtia patients was explored in this study .Method Considering different thickness and tightness in mastoid hairless skin and soft tissue,2129 microtia patients were received the skin expansionmethod of ear reconstruction surgery , while 1321 cases were treated with Nagata ' s technique, and 330 cases with skin and fascia expansionmethod . Result With average 10-month follow-up,1944 ( 91.31％) cases using the mastoid skin expansionmethod were satisfied with the outcome of the reconstructed ear including three dimensional position and subunit appearance.305(92.42％)cases using the skin and fascia expansionmethod were satisfied with theresult .1264 (95.69％) cases using Nagata ' s two—stagemethod received satisfactory outcomes .49 ( 3.71％) cases showed partial exposure of the cartilage framework .There were no postoperative complications , such as chest wall deformity or affected normal physical function .Conclusion Based on the different physiological characteristics of the mastoid skin and soft tissue ,it's beneficial to select individualized operationalmethod in ear reconstruction for congenital microtia among Chinese patients .
