We report the dispersion and scanning tunneling microscopy （STM） characterization of iso- lated Au-CdSe nanohybrids on atomically fiat Au（111） through surface modifications. The top terminal groups of spacer molecules self-assembled on the surface are found critical for locking the nanohybrids into a well-separated state. The STM results indicate that both thiol and carboxylic terminals are effective in this aspect by making strong interaction with the Au portions of the nanohybrids. An argon ion sputtering technique is also proposed to clean up organic contaminants on the surface for improved STM imaging of individual Au-CdSe nanohybrids. These observations help to enrich technical approaches to dispersing individual nanostructures on the surface and provide opportunities to explore their local electroluminescent and energy transfer properties at the nanoscale.

Osteoporosis is a frequent complication of chronic inflammatory diseases and increases in the pro-inflammatory cytokines make an important contribution to bone loss by promoting bone resorption and impairing bone formation. Omentin-1 is a newly identified adipocytokine that has anti-inflammatory effects, but little is known about the role of omentin-1 in inflammatory osteoporosis. Here we generated global omentin-1 knockout（omentin-1^-/-） mice and demonstrated that depletion of omentin-1 induces inflammatory bone loss-like phenotypes in mice, as defined by abnormally elevated pro-inflammatory cytokines, increased osteoclast formation and bone tissue destruction, as well as impaired osteogenic activities. Using an inflammatory cell model induced by tumor necrosis factor-α（TNF-α）, we determined that recombinant omentin-1 reduces the production of proinflammatory factors in the TNF-α-activated macrophages, and suppresses their anti-osteoblastic and pro-osteoclastic abilities. In the magnesium silicate-induced inflammatory osteoporosis mouse model, the systemic administration of adenoviral-delivered omentin-1 significantly protects from osteoporotic bone loss and inflammation. Our study suggests that omentin-1 can be used as a promising therapeutic agent for the prevention or treatment of inflammatory bone diseases by downregulating the proinflammatory cytokines.

目的观察延时的间歇性肾脏替代治疗(prolonged intermittent renal-replacement therapy,PIRRT)用于维持性血液透析(maintenance hemodialysis,MHD)替代治疗的可行性和安全性。方法回顾性评估2022年10月—2023年3月中国人民解放军联勤保障部队第九四〇医院的MHD患者因疫情管控需行肾脏替代治疗的临床资料。治疗模式选用前后联合稀释的加速静脉-静脉血液滤过(accelerated venovenous hemofiltration,AVVH),按治疗剂量分为25~30 ml/(kg·h)组(低剂量组)和50~60 ml/(kg·h)组(高剂量组)。从电子病历收集评估入院首次PIRRT治疗参数、治疗开始时和结束时血清尿素、钾、磷、二氧化碳,计算尿素下降率(URR)、单室模型尿素清除率(spKt/V)以及治疗期间和结束后不良反应等,比较2组上述指标。结果低剂量组(n=31)和高剂量组(n=36)患者年龄、男性比例、干体质量、血红蛋白水平比较均无统计学差异(t=1.388、0.459、0.479、0.913,P=0.085、0.498、0.683、0.818)。高剂量组PIRRT血流量、治疗剂量、滤过分数均高于低剂量组(t=14.535、39.358、7.304,均P<0.001)。2组患者总净超滤量比较无统计学差异(t=1.076,P=0.857)。治疗结束时,2组患者血钾、磷、二氧化碳水平均达正常范围。高剂量组URR及spKt/V均高于低剂量组,差异有统计学意义(t=12.039、5.145,均P<0.001)。2组患者PIRRT期间均未发生明显不良反应。结论PIRRT能够有效纠正MHD患者容量超负荷、电解质和酸碱紊乱;与低剂量PIRRT相比,高剂量PIRRT更能有效降低尿毒症毒素水平,且患者耐受性良好,更适用于MHD的替代治疗。
