The survey collected patient general information and anesthesia data, including overall medical experience and pain management. Thirty minutes after colonoscopy surgery, samples of venous blood were collected and the biochemical indicators of gastrointestinal function were analyzed. RESULTS: There were 98 female and 62 male respondents. Indolent colonoscopy was found to be more suitable for mid to older-aged patients. The necessary conditions for the diagnosis of digestive diseases were required in 65 of the 73 inpatients. Adverse reactions to the intraoperative process included two cases of body movement and two cases of respiratory depression. Gastrin and vasoactive intestinal peptide levels were slightly increased. However, somatostatin and endothelin levels were slightly decreased. CONCLUSION: This study revealed that dezocine combined with propofol can be successfully used for the anesthetization of indolent colonoscopy patients without pain and should be widely used.展开更多

The vast majority of investigations on AD-related synaptic impairment focus on synaptic plasticity, especially the decline of long-term potentiation of synaptic transmission caused by extracellular Aβ42. Changes in other aspects of synaptic and neuronal functions are less studied or undiscovered. Here, we report that intraneuronal accumulation of Aβ42 induced an agedependent slowing of neuronal transmission along pathways involving multiple synapses.展开更多
