Mitochondrial Rho-GTPase 1 (MIRO1) is an outer mitochondrial membrane protein which regulates mitochondrial transport and mitophagy in mitosis. In present study, we reported the crucial roles of MIRO1 in mammalian oocyte meiosis and its potential relationship with aging. We found that MIRO1 expressed in mouse and porcine oocytes, and its expression decreased in aged mice. MIRO1 deficiency caused the failure of meiotic resumption and polar body extrusion in both mouse and porcine oocytes, which could be rescued by exogenous MIRO1supplementation. Mass spectrometry data indicated that MIRO1 associated with several cytoskeleton and cell cycle-related proteins, and MIRO1 regulated motor protein Dynein for microtubule-organizing centers (MTOCs) dynamics at germinal vesicle (GV) stage, which determined meiotic resumption. Furthermore, we found that MIRO1 regulated Aurora A and kinesin family member 11 (KIF11) for meiotic spindle assembly in oocytes. Besides, MIRO1 associated with several mitochondria-related proteins dynamic-related protein 1 (DRP1),Parkin and lysosomal-associated membrane protein 2 (LAMP2) for mitochondrial dynamics and mitophagy during oocyte meiosis. Taken together, our results suggested that MIRO1 played pivotal roles in meiotic resumption, spindle assembly and mitochondrial function in mouse and porcine oocytes, and its insufficiency might contribute to the oocyte maturation defects during aging.

目的分析血清糖化清蛋白（GA）在早期诊断糖尿病肾病中的应用价值,为临床检测和诊断疾病提供新的方法.方法连续收集本院2013年3月至2014年3月诊断为2型糖尿病患者共65例,所有患者门诊及住院定期监测空腹血糖、HbA1c、24 h尿蛋白定量和GA水平,均根据糖尿病治疗指南给予合理的降糖药物或胰岛素治疗,预防并发症.随访约1年后的糖尿病肾病的发病率（糖尿病肾病均经肾穿刺活检＋病理诊断确诊）,对比分析糖尿病肾病组及非糖尿病肾病组患者的危险因素.结果 65例患者随访平均（19.8±4.6）月,共诊断糖尿病肾病23例,发病率为35.38%.两组患者的空腹血糖、HbA1c和24 h尿蛋白定量的比较,差异均无统计学意义（P〉0.05）;而糖尿病肾病组的GA水平显著高于非糖尿病肾病组,差异有统计学意义（P〈0.05）.纳入多因素Logistic回归分析可知,糖尿病病史、血糖水平、GA水平和24 h尿蛋白定量均是影响糖尿病肾病的独立危险因素,且GA水平的危险度较高（OR=1.527）.糖尿病肾病组内不同分期的比较,差异有统计学意义（P〈0.001）,GA水平随着病情加重而逐渐升高.GA水平与HbA1c间的Pearson检验,可知无相关性（r=0.123,P=0.527）.结论血清糖化清蛋白可作为短期和较早诊断糖尿病肾病的重要指标.

Developing a bridge capping layer between perovskite and hole transport layer materials（HTMs） in the n-i-p perovskite solar cells（pero-SCs） is an effective approach to modify the morphology of HTMs and passivate the perovskite ***, we select the quinoxaline-based bifunctional passivation agent, quinoxalin-6-yl-methylamine hydrochloride（Qx MACl）,as the bridging layer, and a D-A copolymer PBQ12 containing the same quinoxaline unit as an HTM for the n-i-p pero-SCs. Due to the π-π stacking among the common quinoxaline units in the bridge layer and HTM, Qx MACl induces the π-π stacking of the PBQ12 film and improves the film morphology of HTMs with better conductivity. Additionally, Qx MACl can effectively passivate the perovskite surface, and PBQ12 possesses appropriate energy levels and high hole mobility. The pero-SCs based on FAPbI3with PBQ12/Qx MACl treatment showed a higher power conversion efficiency（PCE） of 24.05% and outstanding stability, maintaining 95.4% and 92.1% of its initial PCE after 750 h of storage and after over 800 h of thermal annealing at 85 °C, respectively. To further enhance the PCE of the PBQ12/Qx MACl-based devices, we developed a non-metal ion dopant for the PBQ12 HTM. Through trace doping of PBQ12 HTM by the non-metal ion dopant, the PCE of the PBQ12/Qx MACl-based devices reached 25.24%（the calibrated PCE of 24.55% by the National Institute of Metrology, China）.

将糯米淀粉放入膨化机内加热加压,可得膨化糯米淀粉,并观察其在水中溶解性能及粘接强度。膨化糊化比加热糊化和加碱糊化更容易操作,糊化程度容易控制,糊化更彻底。从TG和DTG可知,膨化糯米淀粉的热稳定性更大;糯米淀粉经过膨化后颗粒崩解,亲水性羟基裸露在外面的更多,水溶性明显增大,在IR光谱图上显示为羟基吸收峰明显变宽变大;从SEM图可看出,膨化糯米淀粉的颗粒表面粗糙,更易与水亲和。结果表明,膨化糯米淀粉易溶于水、粘接强度大,在粘接剂行业、医药领域有广泛的应用。
