1Boundary Perturbed Problem for Reaction Diffusion Time Delay Equation with Two Parameters显示文摘The singular perturbation problem for reaction diffusion time delay equation with boundary perturbation is considered. Firstly, the outer solution for the initial boundary value problem is constructed. Then, the initial and boundary layer correction terms are obtained using the stretched variables transforms. Finally, the asymptotic behavior of solution for the initial boundary value problem is studied.XU Yonghong SHI Lanfang MO Jiaqi 2015Wuhan University Journal of Natural Sciences2015,20,2:3
2Effects of active and passive training apparatus combined with rehabilitation training on lower limb function of stroke patients during recovery period显示文摘BACKGROUND: Stroke patients always spontaneously do some learning and training of motor functions; however,learning and training are not prompt and right,while patients do not have enough activity amounts. Active and passive motor training apparatus is aimed directly at lower limb training so as to stimulate nerve function through stimulating muscular movement. Based on motor mileage,motor time,various power supplies and velocity of active and passive training apparatus,we can understand the training condition and adjust training program. OBJECTIVE: To observe the effects of grade-Ⅲ rehabilitation training combining with active and passive training apparatus on lower limb function,muscle strength and activity of daily living (ADL) in stroke patients during recovery period. DESIGN: Contrast observation. SETTING: Department of Rehabilitation,Jilin Academic Institute of Traditional Chinese Medicine. PARTICIPANTS: A total of 80 patients with stroke-induced hemiplegia after stabilizing vital signs for 2 weeks were selected from Department of Rehabilitation,Jilin Academic Institute of Traditional Chinese Medicine from January to June 2007. There were 47 males and 33 females,and their ages ranged from 41 to 75 years. All patients met the diagnostic criteria of the Fourth National Cerebrovascular Disease Academic Meeting in 1995 and were diagnosed as cerebral hemorrhage or cerebral infarction through CT or MRI examinations in clinic. Patients and their parents provided the confirmed consent. Based on therapeutic orders of hospitalization,patients were randomly divided into treatment group and control group with 40 patients in each group. METHODS: Patients in the control group received physical therapy and occupational therapy combining with rehabilitative treatment based on grade-Ⅲ rehabilitative treatment program,which was set by the National Cerebrovascular Disease Topic Group. In addition,patients in the treatment group were trained with active and passive motor training apparatus based on therapeutic procedures in the control group. The active and passive motor training apparatus was designed as the therapeutic style of nervous system; otherwise,the treatment was performed once a day,30 minutes once and 6 times per week. Four weeks were regarded as a course. MAIN OUTCOME MEASURES: Before treatment,at 2 weeks after treatment and after the first course,bare-handed muscle strength examination was used to check muscle strength and muscular tension; in addition,simple Fugl-Meyer assessment (FMA) and diagnostic criteria which were set by the Fourth National Cerebrovascular Disease Academic Meeting were used to evaluate motor function of limbs and total ADL. RESULTS: All 80 stroke patients were involved in the final analysis. ① Muscle strength of lower limbs was improved in both treatment group and control group. After the first course,muscle strength in the treatment group was obviously superior to that in the control group (χ2=6.64,P < 0.05). ② After the first course,Fugl-Meyer scores in the treatment group were higher than those in the control group,and there was significant difference (t =2.82,P < 0.05). ③ Muscular tension of lower limbs was not changed in both treatment group and control group after treatment (P > 0.05). ④ After the first course,ADL in the treatment group was superior to that in the control group (P < 0.05). Among patients in the treatment group,24 cases (60%) had obvious progress,16 (40%) had progress,and 0 (0%) did not have any changes. On the other hand,among patients in the control group,13 cases (32.5%) had obvious progress,26 (65%) had progress,and 1 (2.5%) did not have any changes. CONCLUSION: Rehabilitation training combining with active and passive motor training apparatus can promote the recovery of lower limb disorder,increase muscle strength,control spasm,improve ADL and cause satisfactorily clinical effects in stroke patients during recovery period.Yang Tian Lanfang Shi Lei Jing Le Li Bin Chen Ke wei Zhao 2007Neural Regeneration Research2007,2,10:1
3Generalized Interior Shock Layer Solution of Nonlinear Singularly Perturbed Elliptic Equation for Higher Order显示文摘A class of singular perturbation boundary problem of elliptic equation for higher order is studied. Firstly, under suitable conditions, the generalized outer solution to reduced problems is considered. Then the generalized interior shock asymptotic solution to original problem is constructed by using the theory of generalized functions. Finally, using the fixed point theorem of functional analytic, the uniformly validity of the generalized asymptotic solution with interior shock and boundary layers is proved.SHI Juanrong SHI Lanfang MO Jiaqi 2016Wuhan University Journal of Natural Sciences2016,21,3:0
4Double Traveling Wave Solutions of the Coupled Nonlinear Klein-Gordon Equations and the Coupled Schrdinger-Boussinesq Equation显示文摘The new multiple(G′/G)-expansion method is proposed in this paper to seek the exact double traveling wave solutions of nonlinear partial differential equations.With the aid of symbolic computation,this new method is applied to construct double traveling wave solutions of the coupled nonlinear Klein-Gordon equations and the coupled Schrdinger-Boussinesq equation.As a result,abundant double traveling wave solutions including double hyperbolic tangent function solutions,double tangent function solutions,double rational solutions,and a series of complexiton solutions of these two equations are obtained via this new method.The new multiple(G′/G)-expansion method not only gets new exact solutions of equations directly and effectively,but also expands the scope of the solution.This new method has a very wide range of application for the study of nonlinear partial differential equations.Lanfang SHI Ziwen NIE 2017Journal of Mathematical Research with Applications2017,37,6:0
