ABSTRACT
Objective To investigate the effect of different pressure CO 2 pneumoperitoneum on early postoperative cognitive function in female patients undergoing gynecological laparoscopic sur-gery.Methods Ninety female patients,aged 40-60 years,ASA physical status Ⅰor Ⅱ,scheduled for elective gynecological laparoscopic surgery,were randomly divided into three groups (n = 30). The pressure of CO 2 pneumoperitoneum were set at 6-8,9-1 1 and 12-14 mm Hg in groups L,M and H,respectively.All of the patients were tested by the neuropsychology and questionnaire review to estimate whether the patient got cognitive decline at 24 h before the operation.The venous blood sam-ples 10 minutes before anesthesia (T1 ),at the end of surgery (T2 ),6 hours after surgery (T3 ),24 hours after surgery (T4 )and 72 hours after surgery (T5 )were collected for determination of serum concentrations of NSE and S100βprotein.The pH,PaCO 2 and PaO 2 were recorded before anesthesia (Ta ),before pneumoperitoneum (Tb ),1 hour after pneumoperitoneum (Tc ),2 hours after pneumo-peritoneum (Td )and 1 hour after stopping pneumoperitoneum (Te ).Results Scores of these tests in three groups were not different and there was no patient with cognitive decline after surgery.Com-pared with group H,the concentration of NSE at T2 and T3 was significantly lower in groups L and M (P <0.05).Compared with group H,the concentration of S100βprotein at T2 was significantly lower in groups L and M (P <0.05).Compared with group L,pH at Tc and Td was significantly decreased in groups M and H (P <0.05).Compared with group L,PaCO 2 was significantly increased at Tc-Te in groups M and H (P <0.05).Conclusion Different pressure of CO 2 pneumoperitoneum has no ob-vious effect on the early cognitive function,but low (6-8 mm Hg)CO 2 pneumoperitoneum can reduce the release of NSE and S100βprotein after operation.

ABSTRACT
OBJECTIVE:To investigate the inhibitory effect of Baixuan xiatare tablet on the model mouse with allergic contact dermatitis (ACD). METHODS:60 BALB/c mice were equally randomized into normal control (isometric solvent) group,model (isometric solvent)group,ebastine(positive control,0.003 g/kg)group and the groups of high,middle and low doses of Baixuan xiatare tablet(2.0,1.0 and 0.5 g/kg). The mice were given drugs,ig,once daily for 14 consecutive days. 0.5% 2,4-dinitrofluoro-benzene(DNFB)acetone olive oil solution was applied,for sensitization,on the prepared mouse’s skins one and two days before administration,and 0.2% DNFB acetone olive oil solution on their left ears 16 days thereafter to establish mouse models of ACD. At 48 h after successful establishment of the models,the thickness of the mouse’s left ear margin was measured and the difference value and swelling degree were calculated;flow cytometer was used to determine the levels of T lymphocyte subsets CD4+ and CD8+ in mouse blood and calculate the ratio of CD4+ to CD8+;the levels of interleukin 4(IL-4)and IL-6 in mouse serum were de-termined. RESULTS:Compared with normal control group,those in the model group had higher difference value of ear margin and swelling degree,lower level of CD4+ in blood and ratio of CD4+ to CD8+,and higher content of IL-6 in serum. There was statisti-cally difference (P<0.01). Compared with model group,those in the groups of high,middle and low doses of Baixuan xiatare tablet had lower degree of left ear swelling and higher level of CD4+ in blood;those in the groups of high and middle doses thereof had lower difference value of left ear margin and level of IL-6 in serum;and those in the group of high dose thereof had higher lev-el of CD8+ in blood. There was statistically significance(P<0.01 or P<0.05). CONCLUSIONS:Baixuan xiatare tablet has inhibi-tory effect to some degree on the mouse model with ACD by a mechanism which may be related to the balance of subsets CD4+and CD8+in blood and the reduction of IL-6 in serum.
ABSTRACT
BACKGROUND: Hippocampal neuron presents remarkably injury in cerebral after seizure of epilepsy. Necrosis and apoptosis are two kinds of neural cell injury after epilepsy and play an important role in neural injury of epilepsy. Being endogenous neural protective transmitter, adenosine may inhibit the release of excitatory amino acid, production of oxygenic free radical and action of nitric oxide. Simultaneously, it can improve cerebral blood flow and anti-convulsion. But it has been unknown concerning to the relationship between adenosine and cell apoptosis after epilepsy yet.OBJECTIVE: To observe the effects of 2-CAdo adenosine-receptor excitant on genetic expression of bcl-2, Bax of hippocampal cells in epileptic rats and further probe into the mechanism of adenosine on anti-convulsion and brain protection.DESIGN: Completely randomized controlled experimental research in which the experimental animals were taken as the objects.SETTING: Pediatrics department and general surgical department of one oil field general hospital, and pediatric internal department of a hospital affiliated to one university.MATERIALS: The experiment was performed in Experimental Zoology Departnent and Pathological Teaching & Research Department of Harbin Medical University from October 2002 to March 2003. Totally 104 Wistar rats of either sex were employed, weighing varied from 200 g to 250 g. The animals were randomly divided, named as normal group 8 rats, epileptic group 32 rats, epileptic & 2-CAdo group 32 rats, and epileptic & physiological saline group 32 rats.INTERVENTIONS: The animal epileptic model was set up by intra-abdominal injection of coriamyrtin 15 mg/kg(provided by Pathology Department of Harbin Medical University. Convulsion presented in all of rats, 5 minutes later after injection, lasting for 1 or 2 minutes. In epileptic & 2-CAdo group, 2-CAdo(provided by ICN company), 0.6 mg/kg, was injected from the vein on the tail 1 hour before coriamyrtin injection and 1 hour after convulsion respectively. In epileptic & physiological saline group, the physiological saline of equal dosage was injected from the vein on the tail 1 hour before coriamyrtin injection and 1 hour after convulsion respectively.MAIN OUTCOME MEASURES: Positive cell counts of bcl-2 and Bax genetic expression in hippocampal CA1 area.RESULTS: Twenty-four hours after epilepsy seizure, neural cell bcl-2 expression was increased in hippocampal CA1 area, was remarkably decreased in 48 hours, and the expression was only little amount in 72 hours, but it was increased again in 7 days. Bax expression began increased in 24 hours after epilepsy seizure, was significantly increased in 48 hours, reached the peak in 72 hours, the expression was the minimum in 7 days. In epileptic & 2-CAdo group, bcl-2 expressions at corresponding times were remarkably increased compared with epileptic group and epileptic & physiological saline group( P＜ 0.05), Bax expressions were remarkably decreased compared with epileptic group and epileptic & physiological saline group( P ＜ 0.05), indicating statistical significance.CONCLUSION: 2-CAdo can reduce apoptosis of hippoeampal neural cells after epilepsy seizure and provide a certain protection for neural cells.
