Abnormal proliferation of vascular smooth muscle cells (VSMCs) plays an important role in several pathological processes of cardiovascular diseases. In this study, the effects of XCT790, a potent and selective inverse agonist of estrogen-related receptor alpha (ERRalpha), on rat VSMCs proliferation and related signal pathways were investigated. The proliferative activity of VSMCs was determined by CCK-8 assay. The mRNA levels of ERRalpha, PGC-1alpha, OPN and MCAD were assayed by RT-PCR. The protein levels of ERRalpha, ERK2 and p-ERK1/2 were evaluated by Western blotting. ELISA was used to assess the protein expression of VEGF. The results showed that XCT790 (5-20 micromol x L(-1)) inhibited rat VSMCs proliferation, and the expression of ERRalpha and its target genes, as well as p-ERK1/2, were also inhibited. XCT790 inhibited VSMCs proliferation in a dose-dependent manner at the dose range from 5 to 20 micromol x L(-1) and in a time-dependent manner at the dose range from 10 to 20 micromol x L(-1). These findings demonstrate that XCT790 inhibits rat VSMCs proliferation by down-regulating the gene level of ERRalpha and thus inhibiting the ERK signal pathway, suggesting that ERRalpha may be a novel potential target for therapeutic approaches to inhibit VSMCs proliferation, which plays an important role in several cardiovascular diseases.

OBJECTIVETo investigate the changes of clinical and EEG features in children with febrile seizures which are prone to epilepsy four years after antiepileptic drugs valproate and/or topiramate treatment.

METHODSOne hundred and thirty-two children with febrile seizures between 2004 and 2005 and who had the indications of antiepileptic drugs treatment were administered with oral valproate and/or topiramate treatment. The children were followed up for four years. Routine blood tests, liver and renal function tests were performed twice a year. Sleeping activation EEG examination was performed once a year.

RESULTSDuring the follow-up of 1 to 10 years, 108 (98.2%) out of 110 children with valproate monotherapy were seizure-free. In the 110 cases, 95 were in the drug withdrawl and 10 were in the drug reduction. All of 13 cases receiving topiramate monotherapy were seizure-free and were in the drug withdrawl. None of the patients showed abnormalities in routine blood tests, liver and renal functions tests. Sleeping activation EEG showed normal in 102 cases, focal discharges in 8 cases, bilateral synchronized spikes in 4 cases and 3Hz spikes and polyspikes in 2 cases.

CONCLUSIONSEarly use of antiepileptic drugs valproate or topiramate is effective and safe in children with febrile seizures which are prone to epilepsy. The majority of the children have a normal sleeping activation EEG after antiepileptic drug therapy.

Objective To characterize contemporary electrographic neonatal seizures by video electroencephalogram (VEEG) and to assess the value and the limitations of two-channel (C3-C4/T3-T4) amplitude-integrated electroencephalogram (aEEG) plus original EEG signals used to diagnose neonatal seizure with video EEG as a golden standard.Methods Sixty-six neonates admitted to Children's Hospital of Fudan University from January 2011 to July 2011 with clinical or suspected clinical seizure were investigated and bedside VEEG were recorded for more than 3 hours.VEEG signals were transformed into three kinds of aEEG signals by Galileo NT PMS software:one-channel aEEG (C3-C4),one-channel aEEG (C3-C4) plus original EEG,two-channel aEEG (C3-C4/T3-T4) plus original EEG.Electrical seizure activity on VEEG was signed out with respect to its occurrence,duration and localization of seizure onset; while aEEG seizure was recorded only with its occurrence.The relationship between aEEG and VEEG was analyzed by Spearman analysis.The value and the limitations of aEEG to diagnose neonatal seizure were evaluated by sensitivity,specificity,positive predictive value and negative predictive value.Results A total of 62 traces were suitable for analysis.(1) VEEG showed 39 seizure activities,among which 8 status epilepticus; and the rest 31 neonates had 352 non-status epilepticus electrical seizures,79.3％ (279/352) of which occurred over the centrotemporal region.(2) Eight cases with status epilepticus on VEEG were all diagnosed as status epilepticus on aEEG.For non-status epilepticus electrical seizures,the sensitivity of aEEG for detection of electrical seizures was as followed:49.1％ (173/352) for one-channel aEEG,54.5 ％ (192/352) for one-channel aEEG plus original EEG,81.2％ (286/353) for two-channel aEEG plus original EEG.Results from one-channel aEEG,one-channel aEEG plus original EEG and two-channel aEEG plus original EEG were all related to VEEG (ρ =0.790,0.907 and 0.953,respectively,P＜ 0.01).(3) Sensitivity of seizure detection was 66.7％ (26/39,95％ CI:0.62-0.81) for one-channel aEEG,74.4％(29/39,95％ CI:0.78-0.96) for one-channel aEEG(C3-C4) plus original EEG and 89.7％ (35/39,95％ CI:0.89-1.00) for two-channel aEEG(C3-C4/T3-T4) plus original EEG.Conclusions VEEG might help aEEG in diagnosis of neonatal seizure.two-channel aEEG (C3-C4/T3-T4) plus original EEG could significantly increase the sensitivity of neonatal seizures indentification.

To study the genotypes of hepatitis B virus (HBV) in patients from Chongqing district and determine the prevalence of autoantibodies in these patients. HBV genotyping was carried out by restriction fragment length polymorphism analysis of venous blood serum samples from 252 chronic hepatitis B (CHB) patients and 25 healthy controls. Indirect immunofluorescent assay was used to detect autoantibodies, including antinuclear antibody, anti-mitochondrial antibody, anti-smooth muscle (SM) antibody, and anti-liver and kidney microsomal antibody. Immunospot assay was used to detect anti-ribonucleoprotein/anti-SM antibodies, anti-SS-A antibody, anti-SS-B antibody, anti-scl-70 antibody, and anti-Jo-1 antibody. Correlations between the production of autoantibodies and patient age and sex and various genetypes of HBV were analyzed by the Chi-squared test. The most frequent HBV genotype in CHB patients was B (67.3%), followed by genotype C (32.7%). Genotypes A, D, E, F, G and H were not detected in any of the CHB patients. The positive rate of autoantibodies was higher in the CHB patients than in the healthy group (76.98% vs. 12.00%, X2 = 44.60, P less than 0.05). There was no significant differences in the autoantibodies profiles of CHB patients carrying the B or C genotypes ( X2 = 0.0016, P more than 0.05). The main HBV genotypes in CHB patients in the Chongqing district are B and C. Autoantibodies are prevalent among these CHB patients, and are correlated with patient age and course of liver disease but not HBV genotype or patient sex.
