Randomized Controlled TrialEffect of epidural analgesia with 0.075% ropivacaine versus 0.1% ropivacaine on the maternal temperature during labor: a randomized controlled study.
A wealth of evidence has indicated that labor epidural analgesia is associated with an increased risk of hyperthermia and overt clinical fever. Recently, evidence is emerging that the epidural analgesia-induced fever is associated with the types of the epidural analgesia and the variations in the epidural analgesia will affect the incidence of fever. The aim of the present study was to investigate the effects of epidural analgesia with 0.075% or 0.1% ropivacaine on the maternal temperature during labor. ⋯ Epidural analgesia with 0.075% ropivacaine may be a good choice for the epidural analgesia during labor.

Clinical values of intraoperative indocyanine green fluorescence video angiography with Flow 800 software in cerebrovascular surgery.
Microscope-integrated near-infrared indocyanine green video angiography (ICG-VA) has been used in neurosurgery for a decade. This study aimed to assess the value of intraoperative indocyanine green (ICG) video angiography with Flow 800 software in cerebrovascular surgery and to discover its hemodynamic features and changes of cerebrovascular diseases during surgery. ⋯ Intraoperative ICG video angiography combined with hemodynamic parameter analysis obtained by Flow 800 software appears to be useful for intraoperative monitoring of regional cerebral blood flow in cerebrovascular disease.

Changes of cerebrospinal fluid pressure after thoracic endovascular aortic repair.
Decreasing the intracranial pressure has been advocated as one of the major protective strategies to prevent spinal cord ischemia after endovascular aortic repair. However, the actual changes of cerebrospinal fluid (CSF) pressure and its relation with spinal cord ischemia have been poorly understood. We performed CSF pressure measurements and provisional CSF withdrawal after thoracic endovascular aortic repair, and compared the changes of CSF pressure in high risk patients and in patients with new onset paraplegia and paraparesis. ⋯ Cerebrospinal fluid pressure was elevated in patients with spinal cord ischemia after thoracic endovascular aortic repair. Sequential measurements of CSF pressure and provisional withdrawal of CSF decreased CSF pressure effectively in high risk patients and provided effective prevention of spinal cord ischemia. Risk factor identification and prophylactic measurements play the key role in prevention of spinal cord ischemia after thoracic endovascular aortic repair.

Diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration in intrapulmonary lesions.
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is considered to have high value in the staging of mediastinal lymph nodes in lung cancer. The current study was conducted to investigate the diagnostic value of EBUS-TBNA in intrapulmonary lesions located near the central airway. ⋯ For intrapulmonary lesions near the central airway highly suspected of cancer, EBUS-TBNA has satisfactory diagnostic value. However, the negative predictive value of this technique is low, so negative results obtained by EBUS-TBNA should be confirmed by other methods.

Relationship between AQP4 expression and structural damage to the blood-brain barrier at early stages of traumatic brain injury in rats.
Although some studies have reported that aquaporin-4 (AQP4) plays an important role in the brain edema after traumatic brain injury (TBI), little is known about the AQP4 expression in the early stage of TBI, or about the correlation between the structural damage to the blood-brain barrier (BBB) and angioedema. The aim of this project was to investigate the relationship between AQP4 expression and damage to the BBB at early stages of TBI. ⋯ The angioedema characterized by BBB damage was the primary type of early traumatic brain edema. It was followed by mixed cerebral edema that consisted of angioedema and cellular edema and was aggravated with time. AQP4 expression was down-regulated during the angioedema attack, but AQP4 expression was upregulated during intracellular edema.
