The main achievements of the project are as follows: 1 the hypothesis that a decrease in seed mass causes an increase in mean dispersal distance has been tested based on the experiments of weed dispersal by wind. The experimental results partly support the hypothesis. The results will help farmers to make an optimal strategy of weed control; 2 a statistic method for inferring probabilistic distribution function of a random variable has been developed, by which probabilistic distribution functions of weed species dispersal have been determined; 3 the reproduction structure of Bromus sterilis has been studied; 4 a more complex CA model with 25 neighborhood cells were built, which can simulate spread of a weed population. This work promotes developments in both theory and application of CA models; 5 the "mean law" in weed control has been proposed. Accordingly, the algorism of patch spring may be calibrated; 6 the "patch" and "true patch" have been mathematically defined so that herbicide can be efficiently applied; 7 simulation validates that initial configurations of weed will affect dispersal of its population and strategies of controlling it, or its distribution patterns affect its dispersal progresses.

主要完成的工作和取得的成果有：1）用实验证实了重量较轻的杂草种子并不一定飞得比较重的远，其结果有助于农民制订杂草的优化控制策略；2）发展了一种推断随机变量分布函数的统计方法并用它来获得了几个杂草种的扩散分布函数；3）对杂草Bromus sterilis的繁殖结构进行了研究；4）建立了一个具有25邻的较复杂的能模拟杂草扩散的CA模型，并在理论和应用方面促进了CA模型的发展；5）在杂草控制方面提出了&平均法则&，据此可对按块施药方法进行校正；6）精确地定义了&块&和&真块&以便在杂草控制中能更有效地使用除草剂；7）模拟证实杂草种群的初始配置影响其扩散和控制策略，或者格局影响过程。

The simultaneity use of Xiao Er Chuan Ke Ye and Cang Er Zi San intervening asthma and allergic rhinitis,comparing simply use Xiao Er Chuan Ke Ye,has the predominance in prolonging time of introducing asthma and reducing the frequency of nodding breathe,which indicated that the treatment of allergic rhinitis has great importance in asthma control and lessen the degree of asthma(frequency of rat nodding breath).3,The combination high-dose group has better therapeutic effect than dexamethasone group,all Chuan Ke Ye groups and combination low,medium group in the prevention and control of allergic rhinitis symptoms,reduced airway hyper responsiveness,while in improving breath difficulties combination high-dose group has similar effect with western medicine group,and better effect than all Chuan Ke Ye groups and combination low,medium group.Its efficacy increased with the prolonging of treatment time,but fewer side effects,which makes the application safer and more reliable.4,Xiao Er Chuan Ke Ye combining with Cang Er Zi San can obviously improve the pathological changes in rats with bronchial airway remodeling,reducing the serum TGF-β1,IL-4,ECP levels,increasing the level of serum IFN-γand the imbalance IFN-γ/ IL-4 ratio.

而运用小儿喘咳液合苍耳子散同时干预哮喘与过敏性鼻炎，较之单纯使用小儿喘咳液治疗哮喘，其在延长引喘时间、减少点头呼吸频度等方面有明显的优势，说明过敏性鼻炎的治疗，对于控制哮喘发生，减轻哮喘发作的程度，有着重要的意义。3、大剂量的合方在预防和控制过敏性鼻炎症状、降低哮喘气道高反应性方面疗效较地塞米松对照组、喘咳液各剂量组及合方小、中剂量组更优，而改善呼吸困难方面则与西药组相当，优于喘咳液各剂量组及合方小、中剂量组，且其疗效随着治疗时间的延长而增加，但副作用更少，使用更加安全可靠。4、小儿喘咳液合苍耳子散能明显改善气道重塑大鼠支气管的病理改变，同时降低血清TGF-β1、IL-4、ECP水平，提高血清IFN-γ水平及失衡的IFN-γ/IL-4比值。

The pathogenesis of asthma can be divided into three stages in immunology. The initial stage is sensibilization, which is closely associated with the activation of T cells. B7/CD28 and CD69 also play a significant role in this process. The second stage is chronic allergic inflammation. The immune dysfunction resulting from the disturbance of TH1/TH2 is a major cause of chronic allergic inflammation, and dominates asthma attack. And the third stage is airway remodeling due to chronic inflammation. Airway remodeling is one of the major causes of refractory asthma, which also contributes to the death from asthma.

哮喘的发病从免疫学角度可以分为三期：初期为致敏阶段，与T细胞激活关系密切，B7/CD28和CD69在这一过程也扮演重要角色；第二期为慢性过敏性炎症阶段，TH1/TH2失衡导致免疫功能紊乱是此阶段的主要原因，在哮喘发作过程中起主要作用；第三期为慢性炎症引起的气道结构重构阶段，是难治性支气管哮喘的重要发病和死亡原因。
