Effects of Transcutaneous Electrical Acupoint Stimulation on the Incidence of Hypoxia in Elderly Patients Undergoing Painless Gastrointestinal Endoscopy: A Randomized Controlled Trial.

Hypoxia is not uncommon in elderly patients during painless gastrointestinal endoscopy. This study aimed to determine the effectiveness of transcutaneous electrical acupoint stimulation (TEAS) in reducing the occurrence of hypoxia symptoms in elderly patients. Patients were randomly and equally grouped into sham control ( = 109) or TEAS group ( = 109) by using the random number table method.

Co-Administration of nalbuphine to improve morphine tolerance in mice with bone cancer pain.

Background: Kappa-opioid receptor (KOR) agonists are known for having opposite and/or different effects compared with Mu-opioid receptor (MOR) agonists. This study is aimed at clarifying the analgesic effect and tolerance of nalbuphine combined with morphine, and quantifying the mRNA and protein expression of spinal MOR and KOR in a mouse bone cancer pain (BCP) model treated with nalbuphine and morphine.

Method: BCP model was prepared in C3H/HeNCrlVr Mice by implanting the sarcoma cells into the intramedullary space of the femur.
