Objective To explore the relationship between IL-1?-511C/T and IL-1?+3953C/T site polymorphisms and the susceptibility of pediatric epilepsy.Methods Under the case-control study,IL-1?-511C/T and IL-1?+3953C/T site polymorphisms in 117 patients with pediatric epilepsy and 95 healthy individuals controls(healthy control group) were analyzed with polymerase chain reaction restriction and fragment length polymorphism(PCR-RFLP),the relationship between IL-1?-511C/T,IL-1?+3953 C/T site polymorphisms and the risk of pediatric epilepsy were analyzed.SAS 8.0 software was used to analyze the data.Results Multiple variate logistic regression analysis revealed that compared with healthy control group,there was no relationship between the IL-1?-511C/T site polymorphisms and the susceptibility of pediatric epilepsy individuals,carrying at least one +3953T variant allele(CT and TT genotypes) had a significantly increased risk for pediatric epilepsy(adjusted OR=2.46,95%CI 1.03-5.87),compared with the wild-type genotype(+3953CC).Furthermore,individuals with epilepsy or febrile seizures family history had a significantly higher risk(adjusted OR=4.12,95%CI 1.28-29.34),compared with those with both CC genotypes.Conclusions These findings support the hypothesis that IL-1?-511C/T site polymorphisms have no relationship with epilepsy,but the IL-1?+3953C/T polymorphism may contribute to the risk of developing pediatric epilepsy.

Objective To explo the antioxidant effect and molecular mechanism of gastrodin (Gas) in epilepsy (EP) rats induced by LiCl-pilocarpine (PILO) . Methods Eighty male SD rats were randomly divided into 5 groups: sham group, EP group, therapy groups (pretreated with 60 mg/kg, 90 mg/kg, 120 mg/kg of gastrodin respectively) . The EP model was esteblished by peritoneal injection of LiCl-PILO. Therapy groups were pretreated with various concerntration of Gas. The control group was given the same dosage of normal saline. The alteration of behavior was observed, the concentration of catalase (CAT), glutathion (GSH), superoxide dismutase (SOD), glutathion reductase (GR), total antioxidtion (T-AOC) and malondialdehyde (MDA) in rats brain cortex were detected by chemical colorimetric method, phosphorylation of p38 was determined by western blot. Results There was no EP seizure in sham group,and the EP seizure degree in therapy groups (gas pretreated groups) was significantly decreased,and had statistically significant difference with EP group (P<0.05) . The EP model rats exhibited a significant decrease in the concentration of endogenous antioxidants (CAT, GSH, SOD, GR and T-AOC), while an increase of the concentration of MDA and phosphorylation p38 protein as compared to sham group (P<0.05) . After treatment of the Gas,treatment group rats attenuated the seizure degree,exhibited a significant increase of the concentration of endogenous antioxidants (P<0.05),while a decrease in concentration of MDA and phosphorylation of p38 as compared to model group (P<0.05) . Conclusion Gas may have a neuroprotective role in central nervous system of epileptic rats modle by down-regulateing the seizure degree and the activity of p38 kinase and up-regulateing the content of endogenous antioxidants.

Objective To explore the activition and polarization of microglia in the epileptic rats induced by lithium chloride-pilocarpine. Methods One hundred male SD rats were randomly divided into five groups: control group and different time points model groups including 1d,3d,7d and 14d. Epilepsy models were established by lithium chloride-pilocarpine intraperitoneal injection. The control group was given the same dosage of normal saline. The morphology change was detected by immunofluorescence,and the expressions of iNOS and Arg-1 were determined by IHC at respective time points. Results Compared the model groups with control group,microglia was activated,synapsis was shorten,volume got bigger,most of them seemed as amoebocyte,the expression of iNOS increased and Arg-1 decreased,especially at 3d.ConclusionThe results from this study indicated that microglia was activated and polarized in epileptic rats induced by pilocarpine.

Objective To evaluate the diagnostic value of EUS in patients with chronic abdominal pain of suspected pancreatic origin.Methods The EUS findings and related clinical data of 106 patients with chronic abdominal pain of suspected pancreatic origin(excluding the patients with suspected pancreatic malignancies)from 1991 to 2004 in PUMCH were retrospectively analyzed.Results(1)The principal dis- ease interpreting the chronic abdominal pain of suspected pancreatic origin(excluding pancreatic malignan- cies)was chronic pancreatitis(CP)(57.5%),the following contributions were other pancreatic diseases (18.9%)and unknown diseases(11.3%).(2)The sensitivity and specificity of EUS for diagnosing CP was 95.1% and 64.4% respectively,the positive predictive value(PPV)and negative predictive value (NPV)was 78.4% and 90.6% respectively.(3)Abhormalities of pancreatic parenchyma structure based on EUS were the main findings(90.2%)in patients with CP and non-homogeneous echo pattern combined with hyper echoic dots or calcification was the predominant feature(52.5%).The value of isolated inhomo- geneity and focal enhanced eehogenicity for diagnosing CP were limited(P＞0.05).Abnormalities of pan- ereatic ductal system were presented in 63.9% of patients with CP and dilation of pancreatic duct was the major feature(34.4%).CP with focal mass(inflammatory pseudotumor)was usually presented as hypo e- choic mass in the pancreatic head based on EUS(90%),which was similar to the EUS feature of pancreatic cancer.(4)The general accordant rate based on EUS with ERCP or BT-PABA were 77.8% and 70.4% re- spectively,and the correct rate based on combine diagnosis were 100% and 95.2%.Conclusion CP is the main source of chronic abdominal pain of suspected pancreatic origin(excluding pancreatic malignancies). EUS has good sensitivity but inadequate specificity for diagnosing CP,while ERCP may be more sensitive than EUS for detecting pancreatic ductal lesions.Pancreatic parenchymal abnormalities contribute the major EUS features of CP but the value of isolated inhomogeneity and focal enhanced echogenicity for diagnosing CP are limited.

Objective To evaluate the gender differences in dose-response curve with cisatra-curium in epileptics.Methods Eighty ASA grade Ⅰ or Ⅱ epileptics were enrolled in this study.All patients were divided into male and the female groups and received the method of single dose injection under midazolam-fentanyl intravenous anesthesia.Each patient received intravenous bolus of 20,30, 40,50μg/kg of cisatracurium respectively.The neuromuscular block was measured by Neuromuscular Transmission Monitor and the responses were defined in terms of the percentages of maximum sup-pression in T1 of TOF of the adductor pollicis muscle.According to log-probit transformation of the data of dose and response,the dose-response curve of cisatracurium was established through linear re-gression.The onset time of cisatracurium was also observed.Results The ED50 ,ED75 ,ED90 ,ED95 values of cisatracurium in male epilepsy patients were 37.2±9.7,48.1±11.3,60.4±12.8,69.3± 14.0 μg/kg and that of female epilepsy patients were 36.6±4.3,47.5±7.7,60.5±14.0,70.1± 19.4 μg/kg.There was no significant difference between the two gender groups.No significant change in onset time was observed among 4 dose groups.Conclusion No gender differences are ob-served in dose-response curve of cisatracurium in epileptics.
