Objective To investigate the effects of different degrees of hemodilution on neurological injury and amino acid content in different brain areas after deep hypothermic circulatory arrest (DHCA) . Methods Forty-eight male adult SD rats weighing 400-450 g were randomly divided into 4 groups ( n = 12 each); group 1 Hct 10% (H1); group II Hct 20% (H2); group III Hct 30% (H3) and control group (C). All animals except those in control group underwent DHCA at 18 ℃ for 90 min (including cooling and rewarming) under general anesthesia with fentanyl, ketamine and droperidol. Different degrees of hemodilution were accomplished by changing the composition and volume of priming solution used in cardiopulmonary bypass (CPB) . Hct was determined before, at the initiation of CPB and beginning of rewarming. PaO2, pH and blood lactate of arterial blood and SO2 of venous blood from internal jugular vein (SjvO2 ) were determined at the beginning and end of cooling and rewarming. The animals were killed and brains removed after recovery of circulatory function for the count of injured neurons and determination of glutamate (Glu), aspartate (Asp), glycine (Gly), ?-aminobutyric acid (GABA) and taurine (Tau) contents in cortex, hippocampus and thalamus. Results The number of injured neurons in hippocampus and parietal cortex was significantly smaller in Hct 30 % group than in the other two groups (P

Objective The study consisted of two parts: in part Ⅰ the effects of propofol or/and procaine on CD18, CD62L expression and superoxide anion (SOA) release of phorbol 12-myristal 13-acetate(PMA) stimulated human neutrophils (PMNs) were studied in vitro; in part Ⅱ the effects of propofol or/and procaine on IL-6 and TNF-?production in endotoxin-stimulated human whole blood were studied. Methods PMNs were separated from the whole blood obtained from healthy 20-40yr old subjects. Part Ⅰ consisted of 9 groups: in group 1 (control) phosphate buffer solution was added to PMNs; in group 2 PMNs were stimulated by PMA 100mg?ml-1 ; in group 3-5 different concentrations of propofol (0.4, 4.0,40?g?ml-1) were added to PMA stimulated PMNs; in group 6-8 different concentrations of procaine (1.5,15,150?g?ml-1 ) were added to PMA stimulated PMNs; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to PMA stimulated PMNs. Part II also consisted of 9 groups: in groupl whole blood was mixed with normal saline; in group2 lipopolysaccharide (LPS) l?g?ml-1 was added to whole blood; in group 3-5 different concentrations of propofol (0.4,4.0,40?g?ml-1) were added to LPS stimulated whole blood; in group 6-8 different concentrations of procaine (1.5, 15, 150?g?ml-1 ) were added to LPS stimulated whole blood; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to LPS stimulated whole blood. CD18, CD62L expressions were measured by flow cytometry. SOA release was determined by cytochrome C reduction in the presence or absence of superoxide dismutase (SOD) . IL-6 and TNF-? production were measured by using radioimmunoassay. Results Propofol or/and procaine depressed CD18 up-regulation, CD62L shedding and SOA release of PMA-stimulated PMNs and propofol was more effective than procaine. Propofol enhanced but procaine inhibited the increased production of TNF-? and IL-6 in the LPS stimulated whole blood but when propofol and procaine were used in combination. The effectof procaine predominated. Conclusions Propofol or/and procaine can attenuate tissue damage induced by neutrophils by inhibiting the function of neutrophils.

Objective To investigate the effect of electro-acupuncture (EA) on vascular permeability in patients undergoing open-heart surgery with CPB. Methods Thirty-two NYHA class Ⅰ or Ⅱ and ASA class Ⅱ or Ⅲ patients with BMI of 19-28 kg/m2 undergoing open heart surgery with CPB were randomly divided into 2 groups ( n = 16 each): Ⅰ control group and Ⅱ acupuncture group . The patients were premedicated with intramuscular phenobarbital 0.1 g, pethidine 50 mg and scopolamine 0.3 mg. Anesthesia was induced with midazolam, propofol, fentanyl and vecuronium and maintained with TCI of propofol and fentanyl in both groups. The patients were acupuncture points (neiguan, lieque, yunmen) were selected for stimulation with stimulator. Acupuncture stimulation was started from 30 min before anesthesia induction and continued until the end of operation. The level of sedation was monitored by BIS and maintained at 40-60 during operation. Urinary microalbumin concentration was used as a parameter of vascular permeability, and was measured before and at the end of operation. Blood samples were taken 24 h before and 24 h after operation for measurement of ALT, AST, total bilirubin, BUN and Cr. Results The two groups were comparable with respect to sex ratio, age, body weight, ASA physical status, and preoperative ejection fraction. There was no significant difference in renal and liver function between the 2 groups.Postoperative urinary microalbumin concentration was significantly lower in acupuncture group than in control group. Conclusion Acupuncture can reduce the effect of open heart surgery performed under CPB on vascular permeability.
