Objective: To explore the effects of “hospital–community integrated transitional care” model on quality of life in patients with chronic obstructive pulmonary disease (COPD). Methods: A total of 117 inpatients with COPD from the Department of Respiratory Medicine in a tertiary general hospital in Nanjing were enrolled by convenience sampling from January to December in 2016 and then were divided into intervention group (n = 60) and control group (n = 57) by random number table. Patients in the intervention group accepted both routine care and hospital– community integrated transitional care for 3 months after discharge. Assessment of quality of life by telephone follow-up or interview within a week before discharge and 1, 3, and 6 months after discharge was evaluated using the Short Form-36 (SF-36) health survey questionnaire. Results: For a total score of quality of life, there was a significant difference between the two groups (P 0.05) except vitality dimension, 1 month after discharge, and there were significant differences in all dimensions, 3 and 6 months after discharge (P < 0.05) Conclusions: Hospital–community integrated transitional care model can improve the quality of life of patients with COPD.

Hydrothermal treatment of MCl2 （ M = Co or Cu ） , NH4 VO3, and 1,10-phenanthroline-5,6-dione （pdon） resulted in the formation of a duplex coordination polymer [ Co （ bpdc ）（ H2O ） 3 ] · H2O （ bpdc = 2,2＇-bipyridine-3,3＇-dicarboxylate） and a chain-like coordination polymer [ Cu （bpy） V2O6 ] （ bpy = 2,2＇-bipyridine ）. X-ray single-crystal structural analysis shows that under hydrothermal conditions and in the presence of different transition metals, the organic reagent pdon was transformed in situ into bpdc and bpy, respectively. Mechanism of the in situ ligand synthesis reaction has been discussed.

Carbon （C） dynamics are central to understanding ecosystem restoration effects within the context of Grain for Green Project （GGP）. GGP stared in China since 2003 to improve the environment. Despite its importance, how total forest ecosystem C stock （FECS） develops fol- lowing land-use changes from cropland to plantation is poorly under- stood, in particular the relationship of C allocation to pools. We quanti- fied C pools in a chronosequence ranging from 0 to 48 years, using com- plete above- and below-ground harvests based on detailed field inventory Stands were chosen along a succession sequence in managed plantations of Korean larch （Larix olgensis Henry.）, a native planting species in the Lesser Khingan Mountains, Northeast of China. The FECS of Korean larch plantation （KLP） were dynamic across stand development, chang- ing from 88.2 ***-1 at cropland, to 183.9 ***·-1 as an average of forest C from 7- through 48-year-old plantation. In a 48-year-old mature KLP, vegetation comprises 48.63% of FECS and accounts for 67.66% of annual net C increment （ANCI）. Soil is responsible for 38.19% and 13.53% of those, and with the remainders of 13.18% and 18.81% in down woody materials. Based on comparisons of our estimate to those of others, we conclude that afforestation of Korean larch plantation is a valid approach to sequester carbon.

A new dinuclear complex, [Ag（L）（CH3CN）]2（ClO4）2·2H2O（L=2,3-di-2-pyridylquinoxaline）, was prepared and characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction analyses. The interaction of the complex with calf thymus DNA（CT-DNA） was investigated by absorption, fluorescence spectroscopies, and viscosity measurement. The results suggested that the complex was bound to DNA via an intercalative mode. The intrinsic binding constant value Kb was found to be approximately 1.48×10^3 L·mol^-1. Moreover, the Ag（I） complex could cleave the plasmid pUC19 DNA from the supercoiled Form Ⅰto the nicked FormⅡ under irradiation at 365 nm.

We investigate transport through a perfect quantum wire with a side-coupled quantum dot under an ac field. Time-averaged complex conductance is formulated by using the nonequilibrium Green function （NGF） method. We find that the electron-photon interaction together with the quantum interference of electron wave function can lead to anti-resonance in the conductance, which is then useful for tuning coherence and phases of electrons. Meanwhile, we study the temperature dependence of the conductance. Interestingly, a peak-structure can be developed at the Fano resonance levels with increasing temperatures.

Laboratory experiments were conducted in different sequence and thickness of the soil layers to investigate the effects of layered-textural soils on wetting patterns and water and nitrate distributions from a surface point source under various combinations of application rate and applied volume. Three layered soils, including a sandy-over-sandy loam （SL）, a sandy loam-over-sandy （LS）, and a sandy loam-sandy-sandy loam （LSL）, and two uniform soils （a uniform sandy loam and a uniform sandy soil） were tested. In the experiments, the application rate was varied from 0.69 to 3.86 L h^-1 and the applied volume from 5.7 to 12.1 L. The experimental results demonstrated that the wetting patterns and water and nitrate distributions were greatly affected by the sequence and thickness of soil layers as well as the application rate and volume applied. An interface existing in the layered soils, whether a fine-over-coarse or a coarse-over-fine, had a common feature of limiting downward water movement and of increasing horizontal water movement. For the fine-over-coarse layered soils of LS and LSL, water and nitrate were uniformly distributed at a given depth in the top layer soil. For a coarse-over-fine layered soil of SL, however, water accumulated in the sublayer soil underneath the interface and a zone of lower nitrate concentration was observed. The effect of application rate on water distribution pattern was dependent upon soil layering. A minor influence of application rate on water distribution for the fine-over-coarse layered soils （LS and LSL） than for the uniform soils was found. To obtain a greater wetted depth through selecting the emitters having a smaller application rate, which is a common method in the system design for a uniform soil, may not be necessarily applied for the layered soils. Measurements of nitrate distribution showed that nitrate accumulated toward the boundary of the wetted volume for both the uniform and the layered soils. This suggests the import
