报告内容摘要

From an automation viewpoint, total human body system is simple an automaton in the sense of an autonomously steering production system with built-in functions of control and regulation. From a mathematical viewpoint the total human body system is a complex set of dynamic equations with components of endogenous stochasticity and impact from exogenous dynamic systems with own intrinsic stochasticity. With cells as building stones of tissue, units of functionality must be identified among complexly interacting organ function. Compelling analogies between total human body system and highly complex technical production system are almost a tautology, then. Claims of engineering science properties of technical systems, like robustness in terms of stability, redundancy, modularity and adaptiveness, have been raised in systems biology for cells and tissues, and recourse to universal principles is sought in order to justify a unified multi-scale approach from cell to body.

Hence I will point out the differences with a review of human physiology from a structural automation top-down perspective. This exhibits multiple-use channels with highly optimized control in terms of antagonistic restraint and goal-oriented behavior under prevailing conditions of bipolarity and rhythm. In combination with an apparent highly economical use of resources, this seems more indicative of fragility than stability. Theories built on scale invariant principles are hence not very likely to meet physiological reality. The concept of adaptation will be appropriate in evolution but must be replaced by ‘preservation of integrity’ for whole body functional levels. This governs interaction with body’s outside world, the dynamics of ecological environment and the mostly incalculable dynamics of an even more complex socio-economic life setting.

A challenging corollary is the issue of appropriate metrics for assessment of dynamic system performance. This has interesting implications for clinical diagnosis and treatments as much as epidemiologic studies of risk factors and policy-making in disease prevention.
