| 1 | Pulmonary infection control window in treatment of severe respiratory failure of chronic obstructive pulmonary diseases: a prospective, randomized controlled, multi-centred study显示文摘Background Early withdraw from invasive mechanical ventilation (MV) followed by noninvasive MV is a new strategy for changing modes of treatment. This study was conducted to estimate the feasibility and the efficacy of early extubation and sequential noninvasive MV commenced at beginning of pulmonary infection control window in patients with exacerbated hypercapnic respiratory failure caused by chronic obstructive pulmonary diseases (COPD). Methods A prospective, randomized controlled study was conducted in eleven teaching hospitals' respiratory or medical intensive care units in China. Ninety intubated COPD patients with severe hypercapnic respiratory failure triggered by pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. When the pulmonary infection had been controlled by antibiotics and comprehensive therapy, the 'pulmonary infection control window (PIC window)' has been reached. Each case was randomly assigned to study group (extubation and noninvasive MV via facial mask immediately) or control group (invasive MV was received continuously after PIC window by using conventional weaning technique).Results Study group (n=47) and control group (n=43) had similar clinical characteristics initially and at the time of PIC window. Compared with control group, study group had shorter duration of invasive MV [(6.4±4.4) days vs (11.3±6.2) days, P=0.000], lower rate of ventilator associated pneumonia (VAP) (3/47 vs 12/43, P=0.014), fewer days in ICU [(12±8) days vs (16±11) days, P=0.047] and lower hospital mortality (1/47 vs 7/43, P=0.025).Conclusions In COPD patients requiring intubation and invasive MV for hypercapnic respiratory failure, which is exacerbated by pulmonary infection, early extubation followed by noninvasive MV initiated at the start of PIC window may decrease significantly the duration of invasive MV, the risk of VAP and hospital mortality. | Wang, C Zhan, QY Cao, ZX Wei, LQ Cheng, ZZ Liu, S Zhang, JL Chen, RC Luo, Q Niu, SF Zhu, L Wu, DW Fang, BM Wu, TH Wang, CZ Liu, YN | 2005 | Chinese Medical Journal2005，，19： | 6 |
| 2 | Further geological and palaeoanthropological investigations at the Maludong hominin site, Yunnan Province, Southwest China显示文摘Three-dimensional mapping and section work undertaken by us in 2008 have identified 11 stratigraphic units at Maludong site.AMS radiocarbon dating of charcoal established an accurate and internally consistent age profile for the sequence of 17.8±0.2 ka to 13.2±0.1 ka.Archaeomagnetic analysis showed changes in externally derived pedogenically enhanced material consistent with a warming in climate between the cold period of Henrich Event 1 and the B lling-Aller d interstadial.Human remains recovered during the 1989 excavation were derived from a deposit dating to this interstadial,or between 14.3±0.3 ka and 13.5±0.1 ka.Anthropogenic features,including burnt rocks,baked sediment and thick charcoal and ash layers,were identified and examined through archaeomagnetic analysis.Two monkey fossils are described here,one of them being reassigned from Macaca robustus to M.aff.M.assamensis.They confirm the young age of the site and also show signs of anthropogenic alteration in the form of burning.Additional human cranial remains are reported for the first time and new data are provided for some specimens described previously.A range of new features is identified that strengthen the affinities of the Maludong remains to archaic humans.The presence of this globally unique mosaic of archaic and modern features raises important questions about human evolutionary history in East Asia during the Late Upper Pleistocene. | JI XuePing CURNOE Darren BAO ZhenDe HERRIES Andy I R FINK David ZHU YunSheng HELLSTROM John LUO Yun TACON Paul S C | 2013 | Chinese Science Bulletin2013，58，35： | 3 |
| 3 | Terahertz Semiconductor Quantum Well Devices显示文摘For eventually providing terahertz science with compact and convenient devices,terahertz (1~10THz) quantum-well photodetectors and quantum-cascade lasers are investigated.The design and projected detector performance are presented together with experimental results for several test devices,all working at photon energies below and around optical phonons.Background limited infrared performance (BLIP) operations are observed for all samples (three in total),designed for different wavelengths.BLIP temperatures of 17,13,and 12K are achieved for peak detection frequencies of 9.7THz(31μm),5.4THz(56μm),and 3.2THz(93μm),respectively.A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied.The δ-doping density for each period varies from 3.2×1010 to 4.8×1010cm-2.We observe that the lasing threshold current density increases monotonically with doping concentration.Moreover,the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically.Interestingly the observed maximum lasing temperature is best at a doping density of 3.6×1010cm-2. | Liu H C Luo H Ban D Waichter M Song C Y Wasilewski Z R Buchanan M Aers G C SpringThorpe A J Cao J C Feng S L Williams B S Hu Q | 2006 | Journal of Semiconductors2006，27，4： | 2 |
