Objective To explore the clinical effect of intranasal dexmedetomidine as premedication on sedation and analgesia during painless electronic colonoscopy in children, and to investigate its optimal dose. Methods Ninety children scheduled for painless electronic colonoscopy were divided into three groups by using a computer?generated randomization schedule, 30 per group. Children were pretreated with 0. 2 mg/kg midazolam ( group A) , 1. 0μg/kg dexmedetomidine ( group B) or 2. 0μg/kg dexmedetomidine ( group C) by nasal drip 30 min before operation. The anesthesia protocol was programmed by propofol in the three groups. After eyelash reflex disappeared, the examination was performed. Mean artery blood pressure ( MAP ) , heart rate (HR), respiratory rate (RR) and oxygen saturation (SPO2) of children were recorded at 10 min before intranasal administration ( T0 ) , 30 min after intranasal administration ( T1 ) , at the onset of eyelash reflex disappearance ( T2 ) and the onset of examination initiating( T3 ) , at lens passing through splenic flexure ( T4 ) , or through hepatic flexure ( T5 ) , at the end of examination ( T6 ) and when patients were fully awake ( T7 ) , respectively. Bispectral index ( BIS) and the observer's assessment of alertness/sedation scale ( OAA/S) were performed at 10 min before intranasal administration ( T0 ) , 10 min, 20 min and 30 min after intranasal administration in the three groups. Mood score at parent?children separation and venipuncture acceptance score were also recorded. The adverse reactions during examination were analyzed. The above observed indices were compared among the three groups. If there was statistical difference ( P<0. 05 ) , pairwise comparison was performed ( P<0. 017) . Results The children's haemodynamics were all stable in the three groups. Compared with group A and group B at the same time point, BIS and OAA/S were all lower ( P<0. 017) in 10 to 30 min after intranasal administration in group C. Compared with group A and group B, mood score at parent?children separation and venipuncture acceptance score were both higher ( P<0. 017) in group C. Compared with group A and B, anesthetic revival time and consumption of propofol were shorter or lower in group C (P<0. 017). Compared with group A and group B, the incidences of intraoperative adverse reactions including hypertension, sinus tachycardia, restless moving and postoperative restlessness were all lower in group C(P<0. 017). The rate of intranasal stimulus in group B and group C were both lower than that of group A( P<0. 017) . The rate of injection pain of group C was lower ( P<0. 017 ) than that of group A and B. Conclusion Intranasal administration of dexmedetomidine can be safely applied to children receiving painless electronic colonoscopy, and it can improve children's compliance effectively and yield to satisfactory anesthetic effect. Moreover, the administering efficacy of dexmedetomidine with the dose of 2. 0μg/kg was superior to 1. 0μg/kg.

Objectives: To study the correlation between the dynamic expression of aquaporin-4 (AQP-4) around hematoma and the blood-brain barrier permeability after intracerebral hemorrhage in rats. Methods: Forty-two Sprague-Dawley rats were randomly allocated into sham-operation group, and groups of 6 hours, 12 hours, 1, 3, 7 and 14 days (n=6 in each group) after intracerebral hemorrhage. The intracerebral hemorrhage model in rats was established by injecting autologous arterial blood into caudate nucleus. Immunohistochemical method and Evans blue method were used respectively to detect the dynamic changes of AQP-4 around hematoma and the blood-brain barrier permeability in different time periods after intracerebral hemorrhage in rats. Results: (1) The expression of AQP-4 around hematoma increased gradually 12 hours after intracerebral hemorrhage, it increased significantly at day 1 and reached a maximum at day 3. It was slightly higher than normal level at day 7 and almost returned to normal at day 14 (P

BACKGROUND:Depending on different pH values, nanohydroxyapatite materials have different purities, whether root canal sealers formed by which exert effects on antimicrobial resistance, root canal closure and apical histocompatibility has no reports.
OBJECTIVE:To compare the antimicrobial and sealant properties of nanohydroxyapatite materials with different pH, nanohydroxyapatite-composite and traditional root canal sealants.
METHODS:We detected the antimicrobial action of nanohydroxyapatite with pH 8, 9, 10, Vitapex and AH-Plus root canal sealants with and without addition of ornidazole against three microbial strains namely Enterococcus faecalis, Candida albicans and Staphylococcus aureus using agar diffusion method. And we also analyzed the endodontic microleakage of six root canal sealants by determining the apical reservoir glucose concentration using Glucose Oxidase Method.
RESULTS AND CONCLUSION:Pure nanohydroxyapatite with different pH did not show antimicrobial properties. Addition of ornidazole to nanohydroxyapatite showed greater inhibitory action against Enterococcus faecalis, lesser in Staphylococcus aureus, fol owed by Candida albicans. Vitapex root canal sealer had inhibitory effects only against Staphylococcus aureus. AH-Plus, itself, had antimicrobial activity against al the three strains, but the antimicrobial activity decreased after addition of ornidazole. Nanohydroxyapatite, as a root canal sealant, was superior to zinc oxide eugenol and Vitapex, but inferior to AH-Plus. Addition of ornidazole to nanohydroxyapatite for a short period showed no impact on sealant properties of the material.
