Objective To investigate the effects of multiple doses of propefol on long-term cognitive function in neonatal rats.Methods Twenty-four 7-day old SD rats weighing 12-16 g were randomly divided into 3 groups(n=8 each):group Ⅰ control(C)received intraperitoneal(IP)normal saline(NS)7.5 ml/kg once a day × 7 days:groupⅡ propofol 1(P1)received NS 7.5 ml/kg IP once a day×6 days+propofol 75 mg/kg IP on the 7 th day and group Ⅲ propofol 2(P2)received propefol 75 mg/kg IP once a day × 7 days.Learning and memory function were assessed using Morris water maze when the rats were 4 weeks old.The animals were decapitated immediately after the tests.The cortex and hippocampus were isolated for determination of aspartate (Asp),glutamic acid(Glu),glycine(Gly)and γ-aminobutyric acid(GABA)contents using high performance liquid chromatography(HPLC).Results Long-term learning and memory function significantly declined in group P2 as compared with group C and P1.The content of Asp in hippocampus and the Glu content and Glu/GABA ratio in cortex and hippocampus were significantly lower in group P2 than in group C and P1.There was no significant difference in Gly and GABA content in cortex and hippocampus among the 3 groups.Conclusion Multiple doses of propefol decreases long-term cognitive function by decreasing the levels of excitatory amino acid transmitters in the brain in neonatal rats.

Objective To evaluate the effects of the sciatic nerve block on emergence agitation following sevoflurane-based anesthesia in pediatric patients undergoing foot orthomorphia.Methods Sixty pediatric patients,aged 3-7 yr,weighing 12-20 kg,of ASA physical status Ⅰ or Ⅱ,scheduled for elective foot orthomorphia,were randomly assigned to one of two groups (n =30 each):control group (group Ⅰ) and sciatic nerve block group (group Ⅱ).After induction of anesthesia,laryngeal mask airway was inserted,and artificial or mechanical ventilation was performed.Anesthesia was maintained with inhalation of sevoflurane (end-tidal concentration 0.5％-2.0％) and iv fentanyl 0.5-2.0 μg/kg.The sciatic nerve block on the affected side was performed under the guidance of a nerve stimulator,and 0.25％ bupivacaine 0.5 ml/kg was injected.Laryngeal mask airway removal time and emergence time were recorded.At 30 min of recovery from anesthesia,agitation was scored and the development of emergence agitation was recorded.Pain was evaluated with Faces Pain Scale-Revised (FPS-R) at 10 and 30 min of recovery from anesthesia.Adverse reactions including hypoxemia and nausea and vomiting were also recorded during recovery from anesthesia.Results Compared with group Ⅰ,the intraoperative consumption of fen tanyl and mean end-tidal concentration of sevoflurane were significantly decreased,laryngeal mask airway removal time and emergence time were shortened,and the incidence of emergence agitation,PPS-P scores and incidence of hypoxemia were decreased in group Ⅱ.Conclusion The sciatic nerve block is helpful in decreasing the development of emergence agitation following sevoflurane-based anesthesia in pediatric patients undergoing foot orthomorphia.

Objective To investigate the risk factors of portal venous thrombosis ( PVST) following laparoscopic splenectomy ( LS) in cirrhotic patients with hypersplenism .Methods The clinical data of 62 patients with secondary hypersplenism due to cirrhotic portal hypertension admitted to the Clinical Medical College of Yangzhou University were retrospectively analyzed .These patients underwent LS from January 2013 to April 2014.Based on whether the patients had PVST on postoperative day (POD) 7 or not, the pa-tients were categorized into the non-PVST and PVST groups .Fifteen perioperative variables were analyzed in these two groups .Results On univariate analysis , age and portal vein diameter in the PVST group were significantly higher and velocity of portal blood flow in the PVST group were significantly lower than those in the non-PVST group, (all P<0.05).Bivariate correlation analysis performed for the relationship between these variables and occurrence of PVST on POD 7 showed age >50 years, portal vein diameter >13 mm and velocity of portal blood flow >18 cm/s were significantly correlated .Multivariate logistic regression showed that age >50 years and portal vein diameter >13 mm were significantly independent risk factors of PVST, and velocity of portal blood flow >18 cm/s was an independent protective factor .Conclusion Age>50 years and portal vein diameter >13 mm were independent risk factors , while velocity of portal blood flow >18 cm/s was an independent protective factor of postoperative PVST .

OBJECTIVETo investigate the effects of total flavonoids of propolis (TFP) on apoptosis of myocardial cells of chronic heart failure and its possible mechanism in rats.

METHODSSix male SD rats were randomly selected as normal control group, the remaining rats were made as chronic heart failure (CHF) model by intraperitoneal injection of adriamycin. The rats in the successful model were randomly divided into five groups (n = 6): CHF group, total flavonoids of propolis low dose group (LD group), total flavonoids of propolis middle dose group (MD group), total flavonoids of propolis high dose group (HD group), digoxin group (DIG group). After six week treatment, cardiac function indexes of rats were recorded by signal acquisition system; brain natriuretic peptide (BNP), cardiac troponin I (cTnI), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) content in plasma were detected; Myocardial morphological changes and collagen fiber hyperplasia by HE and Masson staining were observed; Myocardial apoptosis was detected with TUNEL method and protein connexin 43(P-Cx43) expression was detected by Western blot method.

RESULTSCompared with NC group, left ventricular systolic pressure(LVSP) and maximal rise/fall velocity of left ventriculad pressure (± dP/dt(max)) absolute value in CHF group were significantly lowered (P < 0.01) while left ventricular end diastolic pressure (LVEDP) was increased significantly (P < 0.01); Contents of plasma BNP, cTnI, TNF-α and IL-6 in the CHF group were significantly improved (P < 0.01). Compared with CHF group, LVSP, ± dP/dt(max) absolute value in MD and HD groups were increased (P < 0.05), and LVEDP was significantly lowered (P < 0.01); LVEDP in LD group was significantly lowered (P < 0.01), changes in LVSP and ± dp/dt(max) absolue value were not obvious (P > 0.05). BNP, cTnI, TNF-α and IL-6 contents in MD and HD groups were significantly reduced (P < 0.01), but those plasma indicator changes were not obvious in LD group (P > 0.05). Western blot showed that P-Cx43 expression in CHF group was significantly higher than that in NC group (P < 0.01) and that in all TFP treatment groups it was decreased compared with CHF group (P < 0.05, P < 0.01), among which pairwise comparisons also showed differences (P < 0.05), myocardial apoptosis index (%)(22.62 ± 3.39) in CHF group was higher than that in NC group( 1.12 ± 0.24) (P < 0.01); compared with CHF group, the apoptosis index of myocardial cells (%) in LD,MD and HD groups, (15.79 + 2.8), (9.28 + 2.1) and (4.73 + 1.14) respectively, were significantly lower than those in the CHF group( P < 0.01). The expression level of P-Cx43 positively correlated with the apoptotic index (r = 0. 861, P < 0.01).

CONCLUSIONTotal flavonaids of propolis have inhibitory effect on apoptosis of myocardial cells of chronic heart failure induced by adriamycin in rats, and the mechanism may be closely related to the regulation of Cx43 expression, especially the regulatory phosphorylation status.
