95mmHg) were randomly divided into 3 equal groups of 20 each : thiopental group, etomidate group and propofol group. All patients were prmedicated with intramuscular phenobarbital 0. 1g and atropine 0.5mg. Anesthesia was induced with thiopental 4mg?kg-1 or etomidate 0.3mg?kg-1 or propofol 2mg?kg-1, midazolam 0.1mg?kg-1, fentanyl 5?g?kg-1 and vecuronium 0.1mg?kg-1 and maintained with isoflurane inhalation and intermittent boluses of fentanyl and vecuronium. Blood samples were taken before anesthesia(To), 2min after induction(T1) and 2 and 10 min after tracheal intubation (T2, T3) for determination of plasma levels of endothelin(ET), calcitonin gene-related peptide(CGRP), neuropeptide Y (NPY) and neurotensin (NT). Results The three groups were compared with regard to age, sex and weight. BP significantly decreased after induction with thiopental or propofol but increased significantly after intubation in thiopental group and etomidate group. ET and NPY decreased but CGRP and NT increased significantly after induction in thiopental and propofol group. The plasma levels of all four neuropeptides increased significantly after tracheal intubation in thiopental and etomidata group but remained unchanged in propofol group. Conclusions Propofol is the intravenous anesthetic of choice for induction of anesthesia in patients with hypertension.

Objective To observe the changes of calcitonin gene related peptide (CGRP) in rat spinal motoneuron after upper motoneuron injury. Methods Thirty six adult male Wistar rats were selected. Spinal cord transection was made at the lower thoracic segment. The lumbar regions of spinal cord were removed immediately, 1, 2, 4, 7 and 14 days after surgery to be divided into dorsal and ventral sections. The content of CGRP in ventral section was detected using radioimmunoassay method.Results The level of CGRP in spinal motoneuron of the lumbar region was decreased significantly after transection of spinal cord, reached the lowest level on the 2nd day after surgery and then maintained at the low level.Conclusions The upper motoneuron injury can result in the decrease of CGRP content in spinal motoneuron.

Paired box2 ( PAX2 ) is a transciption factor which mainly expressed in the developing kid-ney. Researches indicate that PAX2 promote the transcription through interactions with the adaptor PAX transac-tivation domain interacting protein(PTIP). Otherwise,PAX2 protein can lead to chromatin compaction and gene silencing through interactions with Grg4. PAX2 reexpressed in acute kidney injury and involved in promoting cell proliferation. Congenital PAX2 gene mutation is closely related to congenital abnormalies of the kidney and uri-nary tract. In chronic kidney disease,PAX2 promote proliferation and cyst formation. Here,the recent researches on the function of PAX2 and its role in acute kidney injury and chronic kidney disease are reviewed.
