A Review: A concept of tissue adaptation to hypoxia (i. e. hypoxic preconditioning) was developed and its corresponding animal models were reproduced in 1966s. The methods of model reproduction in rat, rabbit, and mouse in particular and the main results are briefly introduced in this review. The tolerance to hypoxia of preconditioned animals is significantly increased. Regular changes in animals' behavior, neurophysiology, respiratory and circulatory physiology, neuron morphology in vivo and function of brain and spinal cord in vitro are briefly demonstrated. The protective effects in vivo and in vitro of homogenate extract taken from the brain of preconditioned animals, neurochemicals and molecular neurobiological alterations are briefly presented. The essence and significance of tissue adaptation to hypoxia/hypoxic preconditioning are discussed in the review in terms of evolution and practical implication.

OBJECTIVETo evaluate the effect of electro-acupuncture (EA) on gastric mucosal oxygenation and systemic inflammatory response in patients undergoing endoscopic sinus surgery with controlled hypotension (CH), and to explore its protective effect on gastric mucosa.

METHODSFifty-four patients, 18-65 years old, grade I-II of American Society of Anesthesiology (ASA), who were scheduled for endoscopic sinus surgery were randomly assigned to two groups, group A (general anesthesia group) and group B (general anesthesia combined EA anesthesia group), 27 in each group. Conrolled hypotension was executed during operation, and mean arterial pressure (MAP) was maintained at 55-65 mmHg. After tracheal intubation gastric tesiometer catheter was indwelled through nasal cavity or oral cavity. After successful indwelling, it was connected with gastric mucosa monitoring mode of multifunctional parameters monitor. Patients' MAP and heart rate (HR), pHi, partial pressure of carbon dioxide (PgCO2), arterial partial pressure of carbon dioxide (Pg-aCO2) and endtidal pressure of carbon dioxide (Pg-etCO2) were measured and recorded at T, (immediately before induced hypotension), T, (20 min following induced hypotension to target MAP), T2 (40 min following induced hypotension to target MAP), T3 (20 min after ending induced hypotension), and T4(40 min after ending induced hypotension). Blood samples were intravenously collected, TNF-alpha, IL-1, and IL-6 were detected by ELISA 24 h before operation, during operation (T3), and 24 h after operation.

RESULTSAfter hypotension was induced, Pg-CO2, Pg-aCO2 and Pg-etCO2 increased significantly (P < 0.01, P < 0.05), while pHi decreased significantly (P < 0.01) in both groups at T1-T4 than those at T0. During T1-T4, PgCO2, Pg-aCO2, and Pg-etCO2 were higher (P < 0.01, P < 0.05), while pHi was lower in group A than in group B (P < 0.01). Furthermore, TNF-alpha, IL-1, and IL-6 increased significantly in both groups during operation and 24 h after operation, when compared with those 24 h before operation (P < 0.01, P < 0.05). TNF-alpha and IL-1 in group A were higher than those in group B (P < 0.05) during operation and 24 h after operation, but with no significant difference in the plasma concentration of IL-6 (P > 0.05).

CONCLUSIONEA exerted obvious protective effect of gastric mucosal injury in endoscopic sinus surgery with controlled hypotension, which might be achieved by increasing gastric mucosal blood flow, maintaining oxygen supply and demand, inhibiting inflammatory response, and alleviating injury of gastric mucosal barrier.
