On the basis of the-improved self-exchange model of reorganization phenomenon and accurate potential functions from ab initio calculation at HFSCF 6-31G* and DZP levels a new calculation method was,presented for the inner-sphere reorganization energy, values for diatomic molecular redox couples in gas phase electron transfer process have been calculated. Results agree well with the experimental data, and the effectiveness and importance of this method have been demonstrated for calculation of inner-sphere reorganization energy in gas phase electron transfer process.

The induced matching cover number of a graph G without isolated vertices, denoted by imc（G）, is the minimum integer k such that G has k induced matchings M1, M2,..., Mk such that, M1∪M2∪…∪Mk covers V（G）. This paper shows if G is a nontrivial tree, then imc（G） E {△0^＊CG）, △0^＊（G）＋ 1, △0^＊（G）＋ 2}, where △0^＊（G） = max{d0（u）＋ d0（v）： u,v ∈ V（G）,uv ∈ E（G）}.

Background： Pulmonary alveolar proteinosis （PAP） is a rare lung disease, the most common type of which is autoimmune PAP. The gold standard therapy for PAP is whole lung lavage （WLL）. Few studies have reported the optimal technique with which to evaluate the response to WLL. In this study, we aimed to identify parameters with which to assess the need for repeat WLL during a long-term 8-year follow-up. Methods： We conducted a retrospective analysis of 120 patients with autoimmune PAP with 80 of whom underwent WLL. Physiologic, serologic, and radiologic features of the patients were analyzed during an 8-year follow-up after the first WLL treatment. Results： Of the 40 patients without any intervention, 39 patients either achieved remission or remained stable and only one died of pulmonary infection. Of the 56 patients who underwent WLL for 1 time, 55 remained free from a second WLL and 1 patient died of cancer. Twenty-four required additional treatments after their first WLL. The baseline PaO2, （P = 0.000）, PA-aO2 （P = 0.000）, shunt fraction rate （P = 0.001）, percent of predicted normal diffusing capacity of the lung for carbon monoxide （DLCO%Pred）（P = 0.016）, 6-rain walk test （P = 0.013）, carcinoembryonic antigen （CEA）（P = 0.007）, and neuron-specific enolase （NSE）（P = 0.003） showed significant differences among the three groups. The need for a second WLL was significantly associated with PaO2 （P = 0.000）, CEA （P= 0.050）, the 6-minute walk test （P= 0.026）, and DLCO%Pred （P = 0.041 ）. The DLCO%Pred on admission with a cut-off value of42.1% （P = 0.001） may help to distinguish whether patients with PAP require a second WLL. Conclusions： WLL is the optimal treatment method for PAP and provides remarkable improvements for affected patients. The DLCO%Pred on admission with a cut-offvalue of 42.1% may distinguish whether patients with PAP require a second WLL.

The dynamics of a predator-prey system, where prey population has two stages, an immature stage and a mature stage with harvesting, the growth of predator population is of Lotka-Volterra nature, are modelled by a system of retarded functional differential equations. We obtain conditions for global asymptotic stability of three nonnegative equilibria and a threshold of harvesting for the mature prey population. The effect of delay on the population at positive equilibrium and the optimal harvesting of the mature prey population are also considered.

Objective： Low-density granulocytes （LDGs） can form neutrophil extracellular traps （NETs） spontaneously and excessively. When peripheral blood mononuclear calls （PBMCs） are used for studying T lymphocytes, LDGs contained in the PBMCs may decrease the threshold of activating T lymphocytes by forming NETs. This study focused on the profiles of LDGs in common autoimmune diseases and methods for removing LDGs from PBMCs. Methods： The percentages of LDGs in PBMCs from 55 patients with dermatomyositis （DM）, 15 with polymyositis （PM）, 42 with rheumatoid arthritis （RA）, 25 with systemic lupus erythematosus （SLE）, and 19 healthy controls were determined by flow cytometry. Three methods of removing LDGs were explored and compared. After removal, PBMCs from six patients with positive *** were tested again to find out if LDGs contained in the PBMCs could influence T lymphocyte reactions. Results： Significantly higher LDG percentages were found in PBMCs from patients with DM （（8.41±10.87）%, P〈0.0001 ）, PM （（8.41±10.39）%, P〈0.0001 ）, RA （（4.05±6.97）%, P=0.0249）, and SLE （（7.53±11.52）%, P=0.0006）, compared with the controls （（1.28±0.73）%）. The *** values significantly decreased after LDGs were removed. Increasing relative centrifugal force （RCF） within a limited range can decrease the LDG percentage from an initial high level, but not markedly increase the LDG clearance rate. Compared with the whole blood sediment method, the PBMC adherence method can significantly remove LDGs yet scarcely influence the T lymphocyte percentage in PBMCs. Conclusions： The LDG percentage in PBMCs is significantly increased in patients with S/E, DM, PM, and RA. The influence of LDGs on T lymphocytes cannot be ignored in PBMC cultures. The adherence method is a simple and easy-to-use method for removing LDGs and purifying T lymphocytes from PBMCs.

Limited information is available on long-term effects of metal(loid)s pollution incidents. Here, we analyze the distribution characteristics and quantification of elements in the Southwest China Keda mining site, which is one of the most populated sites and enables human health and ecological risk assessments of elemental pollution. The results on modified degree of contamination indicated that the soil and sediment were highly contaminated near Dahu *** health risk of children was almost 2.5 times that of adults in surface water, and 7.1 times in soil, ***, Tl and As were the main health risk contributors in surface water and soil, respectively, and As posed the highest ecological risk both in soil and sediment. These results indicated the potential impact of toxic metal(loid)s on the health of residents and environment. Hence, more scientific attention and proper management need to be paid to this environmental challenge in the future.
