针对超高分子量聚乙烯(UHMWPE)纤维熔点低、易蠕变的缺点,以复合材料热压加工环境为测试条件,通过分析不同热压温度和热压时间下的力学稳定性能,研究UHMWPE纤维的耐高温性能。采用差示扫描量热仪、热重分析仪、扫描电子显微镜、X射线衍射仪、红外吸收光谱分析仪和力学性能测试仪等仪器设备,表征并分析了UHMWPE纤维的力学性能、热稳定性能和微观结构。结果表明:热压温度及时间对UHMWPE纤维性能有着重要的影响。在150℃及以下热压处理时,纤维力学性能随着热压时间的增加而变化不大;在160℃及以上热压处理时,长时间的热处理导致纤维力学性能下降明显,在160℃处理40 s时丝束断裂强力为153 N,强力损失为46.50%;当热压温度大于纤维熔点时,纤维强力出现急速下降,在170℃热压处理10 s时强力下降到了121 N,强力损失达到了57.80%。研究结果可为UHMWPE纤维复合材料的加工及应用提供参考。

The rapid, complete, targeted and safe treatment for tumors remains a key issue in cancer therapy. A novel treatment of solid tumors by supramolecular photocatalyst Nano-SA-TCPP with the irradiation of600–700 nm wavelength is established. Solid tumors(100 mm3) can be eliminated within 10 min. The50-day mouse survival rate was increased from 0% to 100% after the photocatalytic therapy. The breakthrough was owing to the cell membrane rupture and the cytoplasmic loss caused by photogenerated holes inside cancer cells. The porphyrin-based photocatalysts can be internalized in a targeted manner by cancer cells due to the size selection effect, without entering the normal cells. The therapy has no toxicity or side effects for normal cells and organisms. Moreover, the photocatalytic therapy is effective for a variety of cancer cell lines. Because of its high efficiency, safety and universality, the photocatalytic therapy provides us with a new lancet to conquer the tumor.

The Liaonan metamorphic core complex （mcc） has a three-layer structure and is constituted by five parts, i.e. a detachment fault zone, an allochthonous upper plate and an supradetachment basin above the fault zone, and highly metamorphosed rocks and intrusive rocks in the lower plate. The allochthonous upper plate is mainly of Neoproterozoic and Paleozoic rocks weakly deformed and metamorphosed in pre-Indosinan stage. Above these rocks is a small-scale supradetachment basin of Cretaceous sedimentary and volcanic rocks. The lower plate is dominated by Archean TTG gneisses with minor amount of supracrustal rocks. The Archean rocks are intruded by late Mesozoic synkinematic monzogranitic and granitic plutons. Different types of fault rocks, providing clues to the evolution of the detachment fault zone, are well-preserved in the fault zone, e.g. mylonitic gneiss, mylonites, brecciated mylonites, microbreccias and pseudotachylites. Lineations in lower plate granitic intrusions have consistent orientation that indicate uniform top-to-NW shearing along the main detachment fault zone. This also provides evidence for the synkinematic characteristics of the granitic plutons in the lower plate. Structural analysis of the different parts in the mcc and isotopic dating of plutonic rocks from the lower plate and mylonitic rocks from detachment fault zone suggest that exhumation of the mcc started with regional crustal extension due to crustal block rotation and tangential shearing. The extension triggered magma formation, upwelling and emplacement. This event ended with appearance of pseudotachylite and fault gauges formed at the uppermost crustal level. U-Pb dating of single zircon grains from granitic rocks in the lower plate gives an age of 130±2.5 Ma, and biotite grains from the main detachment fault zone have ^40Ar-^39Ar ages of 108-119 Ma. Several aspects may provide constraints for the exhumation of the Liaonan mcc. These include regional extensional setting, cover/basemen

OBJECTIVE： To identify global research trends in three therapies for children with cerebral palsy. DATA RETRIEVAL： We performed a bibliometric analysis of studies on therapies for children with cerebral palsy from 2002 to 2011 retrieved from Web of Science. SELECTION CRITERIA： Inclusion criteria：（a） peer-reviewed published articles on botulinum toxin, constraint-induced movement therapy, or acupuncture for children with cerebral palsy indexed in Web of Science; （b） original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items; and （c） publication between 2002 and 2011. Exclusion criteria：（a） articles that required manual searching or telephone access; （b） documents that were not published in the public domain; and （c） a number of corrected papers from the total number of articles. MAIN OUTCOME MEASURES：（1） Number of publications on the three therapies; （2） annual publication output, distribution by journals, distribution by institution, and top-cited articles on botulinum toxin; （3） annual publication output, distribution by journal, distribution by institution, and top-cited articles on constraint-induced movement therapy; （4） annual publication, distribution by journal, distribution by institution, and top-cited articles on acupuncture. RESULTS： This analysis, based on Web of Science articles, identified several research trends in studies published over the past 10 years of three therapies for children with cerebral palsy. More articles on botulinum toxin for treating children with cerebral palsy were published than the articles regarding constraint-induced movement therapy or acupuncture. The numbers of publications increased over the 10-year study period. Most papers appeared in journals with a focus on neurology, such as Developmental Medicine and Child Neurology and Journal of Child *** institutes publishing on botulinum toxin treatments for this population are mostly in the Neth

In acute ischemic stroke therapy,potent neuroprotective agents are needed that prevent neural injuries caused by reactive oxygen species(ROS)during ischemic ***,a novel 2D neuroprotective agent(AFGd-LDH)is reported,comprising Gd-containing layered double hydroxide nanosheets(Gd-LDH,as a drug nanocarrier/MRI contrast agent),atorvastatin(ATO,as a neuroprotective drug)and the ferritin heavy subunit(FTH,as a blood brain barrier transport agent).Experiments revealed AFGd-LDH to possess outstanding antioxidant activity,neuroprotective properties,blood‒brain barrier transit properties,and *** vitro studies demonstrated the ROS scavenging efficiency of AFGd‒LDH to be~90%,surpassing CeO_(2)(50%,a ROS scavenger)and edaravone(52%,a clinical neuroprotective drug).Ischemia‒reperfusion model studies in mice showed AFGd‒LDH could dramatically decrease apoptosis induced by reperfusion,reducing the infarct area by 67%and lowering the neurological deficit score from 3.2 to ***-LDH also offered outstanding MRI performance,thus enabling simultaneous imaging and ischemia reperfusion therapy.
