[Changes in long-term synaptic plasticity in the spinal dorsal horn of neuropathic pain rats].
To observe the change in induction of long-term potentiation (LTP) of C-fiberevoked potentials in the spinal dorsal horn of neuropathic pain rats, examine the changes in plasticity of synaptic transmission, and explore the effects and mechanisms of central sensitization and neuropathic pain following noxious stimulation or nerve injury. ⋯ These data suggest that the nerve injury itself is likely to induce a state of hyperexcitability at the spinal nociceptive synapses, and further support the notion that the long-term synaptic plasticity and the central sensitization may contribute to the development of neuropathic pain.

[Dynamic observation of the features of chest radiograph in SARS patients].
To observe the radiological features of chest X ray in SARS patients. ⋯ The chest X ray of SARS has some features and its changes can reflect the clinical situation.

Randomized Controlled Trial[Effect of different methods for postoperative pain management on catecholamine response to abdominal surgery].
To observe the effect of different analgesic methods and the influence of catecholamine response to elective abdominal surgery. ⋯ Postoperative patient-controlled epidural or intravenous analgesia could provide effective analgesia. Epidural anesthesia during operation or epidural analgesia postoperation could depress stress responses, thus it is a more effective analgesic method.

Randomized Controlled Trial Comparative Study[Comparison and correlative analysis of pulmonary function markers after extracorporeal circulation].
To compare the clinic significance of three lung function markers after cardiopulmonary bypass operation. ⋯ RI, OI and PaO2/PAO2 all can reflect appropriately the change of lung function after extracorporeal circulation and the monitor of the developmental alterations individually may be more instructive in clinical practice.

Randomized Controlled Trial[Effect of general and epidural anesthesia on autonomic nervous system].
To evaluate autonomic nervous tone during general and epidural anesthesia. ⋯ The autonomic nervous tone is inhibited by both epidural and general anesthesia. EA reveals a shift in the sympathovagal balance toward sympathetic predominance. GA is associated with a shift toward parasympathetic predominance intraoperatively, while postoperatively appears a dramatic increase in LF/HF. Relative to EA, there is a greater effect on autonomic nervous system with GA.
