Living objects have complex internal and external interactions. the complexity is regulated and controlled by homeostasis, which is the balance of multiple opposing influences. the environmental effects finally guide the self-organized structure. the living systems are open, dynamic structures performing random, stationary, stochastic, self-organizing processes. the self-organizing procedure is defined by the spatial-temporal fractal structure, which is self-similar both in space and time. the system’s complexity appears in its energetics, which tries the most efficient use of the available energies;for that, it organizes various well-connected networks. the controller of environmental relations is the Darwinian selection on a long-time scale. the energetics optimize the healthy processes tuned to the highest efficacy and minimal loss (minimalization of the entropy production). the organism is built up by morphogenetic rules and develops various networks from the genetic level to the organism. the networks have intensive crosstalk and form a balance in the Nash equilibrium, which is the homeostatic state in healthy conditions. Homeostasis may be described as a Nash equilibrium, which ensures energy distribution in a “democratic” way regarding the functions of the parts in the complete system. Cancer radically changes the network system in the organism. Cancer is a network disease. Deviation from healthy networking appears at every level, from genetic (molecular) to cells, tissues, organs, and organisms. the strong proliferation of malignant tissue is the origin of most of the life-threatening processes. the weak side of cancer development is the change of complex information networking in the system, being vulnerable to immune attacks. Cancer cells are masters of adaptation and evade immune surveillance. this hiding process can be broken by electromagnetic nonionizing radiation, for which the malignant structure has no adaptation strategy. Our objective is to review

当今世界正面临着多重风险与挑战。资本主义制度深陷危机，匈牙利也深受其害。欧盟正在失去竞争力，欧洲的安全结构已经崩溃，冷战思维挥之不去，人类正面临世界大战的威胁。资本主义无法解决人类面临的各种问题，人们正在寻找新的行之有效的解决方案。套用马克思主义的表述，可以这样说：现在革命形势还没有到来，但是革命形势是可以到来的!我们不知道什么时候会发生，但我们知道，我们应该知道，这是可能发生的。

AIM： to evaluate the gastro-protective effect of capsaicin against the ethanol- and indomethacin （IND）-induced gastric mucosal damage in healthy human subjects. MEtHODS： the effects of small doses （1-8 μg/mL, 100 mL） of capsaicin on the gastric acid secretion basal acid output （BAO） and its electrolyte concentration, gastric transmucosal potential difference （GtPD）, ethanol- （5 mL 300 mL/L i.g.） and IND- （3×25 mg/d） induced gastric mucosal damage were tested in a randomized, prospective study of 84 healthy human subjects. the possible role of desensitization of capsaicin-sensitive afferents was tested by repeated exposures and during a prolonged treatment. RESULtS： Intragastric application of capsaicin decreased the BAO and enhanced “non-parietal” component, GtPD in a dose-dependent manner. the decrease of GtPD evoked by ethanol was inhibited by the capsaicin application, which was reproducible. Gastric microbleeding induced by IND was inhibited by co-administration with capsaicin, but was not influenced by two weeks pretreatment with a daily capsaicin dose of 3×400μg i.g. CONCLUSION： Capsaicin in low concentration range protects against gastric injuries induced by ethanol or IND, which is attributed to stimulation of the sensory nerve endings.
