1The characteristics and recognition of internal-tide and internal-wave deposits显示文摘Internal-tide and internal-wave deposits are a new and important type of deep-water traction-current deposits. Based on an analysis of documented internal-tide and internal-wave deposits, five facies types can be recognized: ( ⅰ ) bidirectional cross-laminated sandstone facies, ( ⅱ ) unidirectional cross-bedded and cross-laminated sandstone facies, ( ⅲ ) rhythmic alternating sandstone facies and mudstone, ( Ⅳ ) flaser, wavy and lenticular bedded foraminiferal limestone facies, ( Ⅴ ) sandy oolitic limestone facies with flaser, wavy and lenticular bedding and epsilon cross bedding, which formed in submarine channel, unchannelized continental slope and plateau environments respectively. Accoding to the available data and knowledge,three sedimentation models are built; some discriminating characteristics of internal-tide and internal-wave deposits, and the distinction between them and contourites and turbidites are summed up.He, YB Gao, ZZ 1999Chinese Science Bulletin1999,44,7:23
2Discovery and demonstration of the teleomorph of Beauve-ria bassiana (Bals.) Vuill.,an important entomogenous fungus显示文摘A Cordyceps specimen was collected in Anhui, China, a strain of Beauveria bassiana, an important ento-mopathogenic fungus for biological pest control, was isolated and their relationship was demonstrated by microcycle co-nidiation. The teleomorph is an undescribed species and is named Cordyceps bassiana.Li, ZZ Li, CR Huang, B Fan, MZ 2001Chinese Science Bulletin2001,46,9:16
3The relationship of Imp2 and DR3 genes with susceptibility to type Ⅰ diabetes mellitus in south China Han population显示文摘AIN To study the relationship of Imp2 and DR3genes with type Ⅰ diabetes mellitus.NETHODS Imp2 genotypes and DR3 wereidentified in 68 patients with type Ⅰ diabetesmellitus(Ⅰ-DM)and 71 healthy controls.Then,Ⅰ-DM patients and controls were respectivelyallocated into DR3-positive and DR3-negativegroups.The frequencies of Imp2 and DR3 genein random subjects,and Imp2 genotypes in DR3-matched subjects were compared between Ⅰ-DMpatients and controls.At the same time,Ⅰ-DMpatients were divided into 3 groups based on theonset age of diabetics:group A≤14 years,group B 15-30 years and group C≥31 years.RESULTS The frequency of DR3 in Ⅰ-DMpatients was significantly higher than that incontrols(47% vs 21%,P<0.005),and it wassignificantly higher in group A than that in groupB+C(70% vs 36%,x^2=7.07,P<0.01).Therewas a significant difference among groups withdifferent onset age of diabetics(x^2=8.19,rp=0.33,P<0.05).In random subjects,thefrequency of Imp2.R/R in Ⅰ-DM patients waslower(43% vs 61%,P<0.05)and Imp2.R/Hhigher(53% vs 28%,P<0.05)than that incontrols,and there was no significant differenceamong groups with different onset age ofdiabetics.In DR3-positive subjects,thefrequency of Imp2.R/R in Ⅰ-DM patients waslower(47% vs 87%,P<0.05)and Imp2-R/H higher(47% vs 13%,P<0.05)than that incontrols.In DR3-negative subjects,thefrequency of Imp2.R/H in Ⅰ-DM patients washigher than that in controls(58% vs 32%,P<0.01),but the frequency of Imp2-R/R and Imp2H/H was not significantly different betweenthese two groups.CONCLUSION DR3 gene may be one of thesusceptible genes of Ⅰ-DM,and significantlyrelated to the onset age of diabetics,and thepersons with DR3 may have an younger onsetage of diabeteS.The Imp2-R/R may be theprotective genotype of Ⅰ-DM,and Imp2-R/H thesusceptible genotype.These were not affectedby DR3 gene.Imp-2 genotypes were not relatedwith the onset age of diabetics.Ding HL Cheng H Fu ZZ Deng QL Yan L Yan T 2000World Journal of Gastroenterology2000,6,1:7
4Pulmonary 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 2005Chinese Medical Journal2005,,19:6
5The first internal-tide deposits found in China显示文摘NOT until Gao Zhenzhong and Eriksson studied the Ordovician of Fincastle area, Appalachi-ans, the USA in 1990, did sedimentologist recognize internal-tide deposits in the ancientrecord and begin to use the term of 'internal-tide deposit'.

10Grain Boundary-induced Shielding of Ni-base Single Crystals: Experimental and Analytical Study显示文摘Fracture behavior was studied for Ni-base single crystals and Ni-base bicrystals. The single crystals were machined from the bicrystal specimens to ensure that the single crystal samples had the same properties as those of the grains in the bicrystals. Using the three-point bend specimens, the fracture toughness Kc of single crystals and grain boundaries was measured,respectively. The two toughness values were little dependent on the ratio of the crack length to the height of the specimens. The grain boundary-induced shielding effect of fracture toughness was found in the grain-cracked bicrystals with normal front grain boundaries, The toughness varied with the distance between the crack tip and grain boundary. With the help of SEM analyses and numerical calculations, the mechanisms for the grain boundary-induced shielding are revealed. It is the grain boundary-induced redistribution of stresses and strains near the crack tip that induces the grain boundary-induced shielding. And the strain energy density criterion can be applied to the fracture of bicrystals. Agreement with experiments isYue, ZF Lu, ZZ Wu, DQ 1999Journal of Materials Science & Technology1999,15,5:2
11Human hepatopoietin and its relationship with liver regeneration显示文摘IT is nothing.new to see the regeneration of affiliated organs or limbs in the lower living beings. However, the regeneration ability in higher mammals is extremely limited. Therefore,the regeneration ability possessed peculiarly by mammal liver attracts great attention. That solely high regeneration ability has been discovered for thousands of years and yet the studies on the mechanism were initiated only a hundred years ago. The key breakthrough happened in 1931 when Higgins and Anderson established the hepatic regeneration model by partial hepatectomy in rats. Since then, the successive studies on liver regeneration mechanism have been focused on analysis and identification of the events initiating the regenerative process.He, FC Wu, ZZ 1997Chinese Science Bulletin1997,42,18:2
