迈向教育强国的发展战略探索——评李化树《教育强国：目标、方针与战略》

“国民之智愚贤否，关国家之强弱盛衰”。教育，承载了一个国家、一个民族太多的希望和梦想。纵观世界强国发展的历史，综合国力的提高和强大，元不以教育的强大为基础。当今世界发达国家的战略走向，各国政府都把保持和提升教育发展水平作为施政重点。党的十七大从全面建设小康社会、实现中华民族伟大复兴的战略高度，鲜明的指出：“教育是民族振兴的基石，

《静静燃烧的果核》——关于李化猛的作品

在这五彩斑斓的世界上，总有一些人会让你感到时间是凝止的。就像不动声色的花，却在浮世循环了一千遍。总有那么一些人，他们远远的，却走得更贴切也更深入。这些山寸话者，阳光、雨水直接恩赐的温暖小动物，他们更直接地从自然汲取能量，就像一扇阳光直射的窗子，中间一无阻隔。他们是性灵和美直接显示的赤子。

Lie Point Symmetries and Exact Solutions of Couple KdV Equations

The simple Lie point symmetry reduction procedure is used to obtain infinitely many symmetries to a new integrable system of coupled KdV equations. Using some symmetry subalgebra of the equations, five types of the significant similarity reductions are obtained by virtue of the Lie group approach, and obtain abundant solutions of the coupled KdV equations, such as the solitary wave solution, exponential solution, rational solution, polynomial solution, etc.

Symmetry Reductions and Exact Solutions of Blaszak-Marciniak Four-Field Lattice Equation

Applying the Lie group method to the differential-difference equation, the Lie point symmetry of Blaszak- Marciniak four-field Lattice equation is obtained. Using the obtained symmetry, the similarity reduction equations of Blaszak-Marciniak four-field Lattice equation are derived. Solving the reduction, we get the solution of Blaszak-Marciniak four-field Lattice equation which not only recovers one of the solutions obtained by Ma and Hu [J. Math. Phys. 40 （1999） 6071] but also has the singularity when we choose the arbitrary constants accurately.

Efficacy and safety profile of LCR35 complete freeze-dried culture in irritable bowel syndrome:A randomized,double-blind study

AIM:To assess the effects and safety of Lactobacillus casei rhamnosus LCR35 complete freeze-dried culture(LCR35) in patients suffering from irritable bowel syndrome(IBS).METHODS:A randomized,double-blind pilot study was performed in 50 patients complaining of IBS symptoms complying with RomeⅢcriteria.Patients were allocated to receive either LCR35(n = 25) at a minimum daily dose of 6 × 108 colony forming units or placebo(n = 25) for 4 wk.At inclusion,after treatment and 2 wk later,patients completed the IBS severity scale.Change from baseline in the IBS severity score at the end of treatment was the primary efficacy criterion.Changes were compared between groups in the whole population and in IBS subtypes(IBS with predominance of constipation,IBS with predominance of diarrhoea,mixed IBS,unsubtyped IBS).The presence of lactobacillus casei rhamnosus in stools was investigated at inclusion and at the end of treatment.The gastrointestinal quality of life questionnaire and the hospital anxiety and depression(HAD) scale were also completed.RESULTS:Both groups were balanced for baseline characteristics.In 85% of patients,stool analyses showed that lactobacillus casei rhamnosus able to survive in the digestive tract.In the whole population,improvements in the IBS severity score did not differ significantly between treatments with a 25% decrease after 4-wk treatment,and a 15% decrease from baseline 2 wk later in both groups.In IBS subgroups,statistical analysis could not be performed due to small sample size,but a clinical response in favour of LCR35 was observed in IBS patients with predominance of diarrhoea:no change in the symptom severity score was seen with the placebo after 4 wk treatment,whereas a clinically relevant decrease occurred with LCR35(-37% vs-3%).Furthermore,in spite of an increase in symptom intensity,the IBS severity score was maintained below the baseline value 2 wk later with LCR35(-19% from baseline),whilst a slight 5% increase from baseline was observed with placebo.In the IBS subgroup with predominance of diarrhoea only,a clinically relevant decrease in abdominal pain severity score(-36%)was observed with LCR35,whereas no change occurred with placebo.In mixed IBS patients,the 20% and 30% decreases in the IBS severity score observed after treatment with LCR35 and placebo,respectively,were maintained 2 wk later in both groups.A clinical response slightly in favour of placebo was observed at the end of the treatment period in IBS patients with predominance of constipation(-41% vs-20%) and unsubtyped IBS patients(-47% vs-17%),with the same value maintained 2 wk later.In both groups,no clinically relevant changes were observed either for the gastrointestinal quality of life index or HAD score.Thus,these results suggest that sub-grouping of IBS patients may be important for optimizing treatment responses by the physician.CONCLUSION:This pilot study suggests that LCR35 could have some efficacy in IBS patients complaining of diarrhoea.These preliminary results need to be conf irmed in larger studies.

Effect of PLA/ZnO Packaging and Gamma Radiation on the Content of Listeria innocua, Escherichia coil and Salmonella enterica on Ham during Storage at 4℃

The effect of ZnO and low y-radiation on PLA based-films was investigated to be used for food packaging application. Ham slices were inoculated with E. coli, L. innocua and S. enterica and then covered with PLA and PLA/5% ZnO films. The samples were irradiated with a y-radiation dose of 0.3 kGy at dose rate of 13.5 kGy/h. Microbiological analysis was performed at 0, 1 and 5 days on samples stored at 4 ℃. Results showed that no consistent reduction of bacteria was obtained, even at the fifth day of storage, when the ham was covered with PLA/5% ZnO film and no γ-radiation was performed. The use of γ-radiation results necessary to reduce the bacteria growth. In fact E. coli and S. enterica were not detected after 5 days of storage; whereas in the case of test with L. innocua a reduction of 1.3 log CFU/g was observed after 5 days of storage. The antibacterial results indicate that the presence of ZnO in PLA film is effective only for E. coll. The differences of the results obtained here with those reported in literature （where ZnO particles are reported to be very effective as antimicrobial material） are accounted for the different methodologies used. In conclusion considering the positive results, even if small, obtained here at least only for the E. Coli and considering that PLA/5% ZnO film shows, compared to plain PLA film, good tensile properties （especially Young＇s modulus and stress at yielding） and good permeability （to O2 and CO2） induce to consider the PLA/5% ZnO composite film usable for food packaging when long shelf life and food safety are required, considering also that it is biodegradable and compostable.

A New Liouville Integrable Hamiltonian System

With the help of a Lie algebra, an isospectral Lax pair is introduced for which a new Liouville integrable hierarchy of evolution equations is generated. Its Hamiltonian structure is also worked out by use of the quadratic-form identity.

Lie Algebras for Constructing Nonlinear Integrable Couplings

Two new explicit Lie algebras are introduced for which the nonlinear integrable couplings of the Giachetti- Johnson （G J） hierarchy and the Yang hierarchy are obtained, respectively. By employing the variational identity their ttamiltonian structures are also generated. The approach presented in the paper can also provide nonlinear integrable couplings of other soliton hierarchies of evolution equations.

Highly Efficient Asymmetric Transcyanation of Acetyltrimethylsilane with Acetone Cyanohydrin Catalyzed by (R)-Oxynitrilase from Prunus Japonica Seed Meal

Highly efficient asymmetric transcyanation of acetyltrimethylsilane with acetone cyanohydrin in an aqueous/organic biphasic system catalyzed with （R）-oxynitrilase from defatted Prunus Japonica seed meal for the preparation of optically active （R）-2-trimethylsilyl-2-hydroxyl-propionitrile was successfully carried out for the first time. For better understanding of the reaction, various influential variables were examined with respect to the initial reaction rate, the substrate conversion and the product enantiomeric excess （e.e.）. Diisopropyl ether was found to be the best organic phase for this reaction among all the organic solvents tested. The optimal concentrations of Prunus Japonica seed meal powder, acetyltrimethylsilane and acetone cyanohydrin, volume ratio of aqueous phase to organic phase, buffer pH value and the reaction temperature were 34.5g·L^-1 and 14mmol· L^-1, 28mmol· L^-1, 13% （by volume）, 5.0 and 30℃, respectively, while the initial reaction rate, the substrate conversion and the product enantiomeric excess were 1.34 mmol·L^-1·h^-1, 99.0% and 99.0%, respectively. The comparative study demonstrated that silicon atom in substrate showed great effect on the reaction and acetyltrimethylsilane was a much better substrate for （R）-hydroxynitrile lyase from Prunus Japonica seed than its carbon analogue 3,3-dimethyl-2-butanone.
