Chinese Journal of Anesthesiology 2011;31(2):144-146
Objective To compare the effect of different methods of anesthesia on cerebral autoregulation in patients undergoing neurosurgery.Methods Sixty-nine ASA Ⅱ orⅢ patients with brain tumor, aged 23-62 yr, scheduled for neurosurgery under general anesthesia, were randomly divided into 3 groups ( n = 23 each) : propofol-remifentanil group (group PR), sevoflurane-remifentanil group (group SR) and propofol-sevoflurane-remifentanil group (group PSR) . Anesthesia was induced with target-controlled infusion (TCI) of propofol (target plasma concentration3 μg/ml, PR and PSR groups) or inhalation of 8% sevoflurane (group SR) and iv injection of remifentanil 1 mg/kg and atracurium 0.5 mg/kg. The patients were mechanically ventilated after tracheal intubation. PETCO2 was maintained at 32-35 mm Hg. Anesthesia was maintained with TCI of propofol (target plasma concentration 2.0-3.5 μg/ml) in group PR, with inhalation of 1.5%-2.5% sevoflurane in group SR, with TCI of propofol (target plasma concentration 1.5-3.0 μg/ml) and inhalation of 1% sevoflurane in group PSR, and with TCI of remifentanil (target plasma concentration 2.0-4.5 ng/ml) and iv infusion of atracurium at 6 μg · kg-1 · min-1 in all groups. Auditory evoked potential index was maintained between 40-45. The middle cerebral artery time-average peak flow velocity was recorded before induction (baseline) , immediately after intubation, immediately before craniotomy and at the beginning of skin suture. The unilateral carotid artery was compressed for 7 s at the corresponding time points mentioned above. The transient hyperemic response ratio (THRR) was calculated to reflect cerebral autoregulation. Results Compared with the baseline value at T0, THRR was significantly increased at T2in group PR and decreased at T2,3 in group SR (P <0.05) ,while no significant change was found in THRR at T1-3in group PSR (P >0.05). The THRR was significantly lower in SR and PSR groups than in group PR, and higher in group PSR than in group SR ( P < 0.05). Conclusion Propofol-remifentanil anesthesia can improve cerebral autoregulation, sevoflurane-remifentanil anesthesia can reduce cerebral autoregulation, and propofol-sevofluraneremifentanil anesthesia exerts no effect on cerebral autoregulation in patients undergoing neurosurgery.
5.Relationship between obesity levels and adipocytokines in children
Chinese Journal of Postgraduates of Medicine 2010;33(10):33-35
Objective To explore the relationship between obesity levels and adipocytokines like leptin,adiponectin and resistin in children.Methods One hundred and ten patients aged 2-6 years with simple obesity were selected into obesity group,which included 40 cases of slight obesity (slight obesity group),40 cases of medium obesity (medium obesity group) and 30 cases of severe obesity (severe obesity group).Forty cases of healthy children with normal bodyweight were included in control group.Their serum leptin,adiponectin and resistin levels were tested and compared.Results Serum leptin and resistin levels in obesity group were remarkably higher than those in control group (P < 0.01),whereas adiponectin level was much lower than that in control group (P< 0.01).Serum leptin and resistin levels in medium obesity group were remarkably higher than those in slight obesity group [(14.3 ±1.9) μg/L vs (7.8 ± 1.5)μg/L and (14.6±2.2) μg/Lvs (13.1 ±3.0) μg/L](P< 0.01),whereas adiponectin level was much lower than that in slight obesity group[(6.7 ± 3.0) mg/L vs (9.1 ± 3.5) mg/L](P< 0.01).Serum leptin and resistin levels in severe obesity group [(20.4 ±4.7),(18.3 ±3.2) μg/L]were remarkably higher than those in medium obesity group(P< 0.01),whereas adiponectin level [(5.1 ± 1.2) mg/L]was much lower than that in medium obesity group (P< 0.01).Conclusion The levels of adipocytokines are closely correlated with obesity level in children,especially for abdominal obesity.
6.Application effect of recombinant human epidermal growth factor derivative Eye drops in treatment of dry eye
International Eye Science 2015;(1):117-119
Abstract? AlM: To investigate the application effect of recombinant human epidermal growth factor derivative eye drops ( Jinyinshu) in treatment of dry eye.?METHODS:Sixty cases ( 87 eyes ) of dry eye patients were randomly divided into control group and observation group, 42 eyes and 45 eyes respectively. The control group received Chondroitin sulfate eye drops treatment, and the observation group were used for treatment of Jinyinshu. The changes of clinical efficacy, correlation index (symptom score, BUT, S l t, FL) before and after treatment, quality of life after treatment and the incidence of adverse reactions were compared.? RESULTS: ln the control group, the total clinical effective rate was 71%, which was significantly lower than that in the observation group ( 91%) , the difference was statistically significant ( P<0. 05 ); There were statistical differences of symptom scores, BUT, S▏t and FL level of the two groups before and after treatment (P<0. 05), and there were statistical differences of the above indexes after treatment between the two groups ( P<0. 05 ); The quality of life score was 142. 16 ± 10. 32 of the observation group after treatment, which was significantly higher than that in the control group after treatment (115. 24±7. 34), the difference was statistically significant (P<0. 05); The incidence of adverse reaction of the control group was 13%, 10% in the observation group, and there were no statistical differences (P>0. 05).?CONCLUSlON:Jinyinshu is significantly effective in the treatment of dry eye, and its clinical efficacy is better than chondroitin sulfate.
8. Factor analysis-based relationship analysis between geographical factors and value of FEV1. 0% in aged Chinese males
Academic Journal of Second Military Medical University 2010;30(11):1269-1273
Objective: To provide a scientific basis for establishing a standard reference value of FEV1. 0% for aged Chinese males. Methods: The reference values of FEV1. 0% of 4 342 healthy aged Chinese males were collected from hospitals, research units, and higher institutions of 72 counties or cities. Correlation analysis, factor analysis and GIS software were used to investigate the relationship between the reference values of FEV1. 0% with six geographical factors. Results: It was found that the reference values of FEV1. 0% in aged Chinese males were significantly associated with geographical factors. Factor analysis and regression analysis yielded a regression equation as: y = 79.279 8 + 0.000 901 5X1 -0. 001 931 4X2 + 0. 001 966 8X 3 - 0.002 615X4+0.001 293 4X5+0.001 650 3X 6 ±1.032 8. The fitting degree between the predicted and the measured values was high. With the aid of geostatistical analysis module of GIS spatial analysis and Kriging interpolation method, we interpolated the geographical distribution map of the reference value of FEV1. 0% in aged Chinese males. Conclusion: The regression equation can be used to accurately calculate the reference value of FEV1. 0% for aged Chinese males, if the geographical values for an area are available. The reference value of FEV1. 0% can also be obtained by the geography Trend-surface distribution map of an area.
