BACKGROUNDRecently, new anti-epileptic drugs (AEDs) have been more frequently selected to treat epilepsy. In the present study, we evaluated the dynamic changes of efficacy and safety of three newer AEDs for treating partial epilepsy in China.
METHODSPatients were collected sequentially and were divided into three groups which accepted oxcarbazepine (OXC), lamotrigine (LTG) or topiramate (TPM) therapy. Each group included monotherapy and add-on therapy subgroups. We followed all patients for one year and recorded the indexes of efficacy and safety in detail.
RESULTSA total of 909 patients finished the follow-up observation. No significant difference was found in proportion of patients with > or = 50% reduction, > or = 75% reduction and 100% seizure reduction in the LTG and OXC groups between the first and the second six months. In the TPM group there was a statistical difference between the first and the second six months in proportion of patients with > or = 50% reduction (P = 0.002), > or = 75% reduction (P < 0.0001) and 100% seizure reduction (P = 0.009) in the monotherapy subgroup, and about > or = 75% reduction and 100% seizure reduction in the add-on therapy subgroup (P < 0.0001). The efficacy between the add-on and monotherapy subgroups showed a statistical difference. The safety of the three newer AEDs was good.
CONCLUSIONSThe three newer AEDs all showed good efficacy and tolerability for partial epilepsy. And the efficacy can be maintained for at least one year.

OBJECTIVE: Aripiprazole, a dopamine system stabilizer, shows efficacy against both negative symptoms and positive symptoms in patients with schizophrenia. The aim of this study was to investigate the effects of aripiprazole and haloperidol on c-FOS expression in rat brain. METHODS: Aripiprazole (1, 10 and 30 mg/kg, i.p.) and haloperidol (0.1 and 1 mg/kg, i.p.) were administered to adult Male Sprague-Dawley rats. After 2 h of drug or vehicle administration, the rats were killed and their brains were removed and perfused with fixative, then cut into 40 microm slices on a freezing microtome. Brain regions of interest were the medial prefrontal cortex (mPFC), the nucleus accumbens core and shell (NAC-C and NAC-S), the hippocampus (CA1, CA3 and DG), the central amygdala (Ce), the basolateral amygdala (BL) and the temporal cortex (Tc). Immunohistochemistry was performed to label cell bodies containing c-FOS. RESULTS: The administration of aripiprazole at all doses (1, 10 or 30 mg/kg) resulted in greater Fos-like immunoreactivity (FLI) in the investigated brain areas, as compared to the vehicle. Comparable increases in FLI were demonstrated in the NAC-C and NAC-S in response to both aripiprazole and haloperidol treatment. The administration of haloperidol (0.1 or 1 mg/kg) also resulted in greater FLI in the investigated brain areas, except the mPFC, where no changes were observed. In the Ce and BL, a significant increase in Fos-positive neurons was observed only with 0.1 mg/kg of haloperidol. CONCLUSION: Both aripiprazole and haloperidol increased FLI in limbic areas, which are considered important targets of antipsychotic drugs. The differential action of aripiprazole on FLI in the amygdala and mPFC as compared to haloperidol may be a good way to differentiate atypical from typical antipsychotics.

OBJECTIVE: The anti-apoptotic protein Bax inhibitor-1 (BI-1) is a regulator of apoptosis linked to endoplasmic reticulum (ER) stress, and BI-1-/- mice exhibit increased sensitivity to tissue damage. The purpose of this study was to investigate the role of BI-1 in the pathogenesis of chronic mild stress (CMS)-induced depression-like behaviors in BI-1-/- mice. METHODS: We delivered CMS for 2 or 6 weeks in BI-1-knockout and wild-type mice. Control groups of BI-1-knockout and wild-type mice were left undisturbed. The measured parameters were sucrose consumption at weeks 1, 2, 3, 4, 5, and 6, spontaneous locomotion, and a forced swimming test (FST) at weeks 2 and 6. RESULTS: Significant decreases in sucrose consumption and increases in immobility time in the FST were observed in both stress groups compared with the non-stress groups. Interestingly, at week 2, but not at week 6, BI-1-/--stress mice showed less sucrose intake and greater immobility time than did BI-1+/+-stress mice. CONCLUSION: These results suggest that BI-1 may play role in protecting against the depressogenic effects of CMS in the short term, but not in the long term. Further study is required to deepen understanding of the role of BI-1 in protecting against depression.

OBJECTIVETo observe the safety and feasibility of tracheal intubation by target-controlled infusion of propofol and remifentanil without muscle relaxant in children.
METHODSTotally 100 4-10-year-old pediatric patients (ASA1) who had been scheduled for plastic surgery were equally divided into remifentanil group and control group through computer-generated randomized grouping. In all patients, five minutes after intravenous administration of atropine 0.01 mg/kg and midazolam 0.1 mg/kg, propofol was infused at the targeted effect-site concentration (Ce of 6 μg/ml. When the intended target Ce of propofol was reached, the remifentanil group began to be infused with remifentanil at a Ce of 5 ng/ml, and normal saline (0.1 ml/kg) was injected simultaneously. In the control group remifentanil was replaced by normal saline and rocuronium (0.8 mg/kg) was injected together with the normal saline. After the equilibration of plasma and the Ce of remifentanil were reached, tracheal intubation was attempted. The complications during the induction and tracheal intubation were recorded. The intubating conditions were assessed using a five-point scoring system based on ease of laryngoscopy, vocal cords position, coughing, jaw relaxation and limb movement.
RESULTSThe success rate of tracheal intubation was in 90% in remifentanil group and 98% in the control group (P=0.122).CONCLUSION Target-controlled infusion of propofol and remifentanil at Ce of 6 μg/ml and 5 ng/ml is feasible for the induction and tracheal intubation without muscle relaxant in children.

OBJECTIVETo evaluate the effect and adverse effects of arsenic trioxide (As2O3) in the treatment of primary hepatocarcinoma patients, and conduct the pharmacokinetics study.
METHODSA total of one hundred and eleven advanced primary hepatocarcinoma patients in five centers were treated with As2O3 injection 7 - 8 mg/m(2) i.v. qd for 14 days and was repeated after 7 - 14 days. Evaluation of the clinical response and adverse effects was conducted after two cycles of treatment. The patient who had reached partial PR and SD was treated continuously until disease progression or intolerance.
RESULTSAmong the 102 patients evaluable for clinical efficacy analysis, there were 7 PR, 71 SD and 24 PD, the response rate was 6.9% and the clinical benefit rate was 76.5%. The quality of life was improved in 22.5% of patients. The pain relief rate was 71.7%, time to progress (TTP) was 97 days, and the median survival time (MST) was 195 days. The major adverse effects were reversible WHO I-II grade gastrointestinal reactions and bone marrow suppression. The results of pharmacokinetic study showed that the distribution and elimination characteristics in vivo was found to be a two-compartment model. The plasma elimination half-life was (23.94 ± 18.39) h.
CONCLUSIONSAs2O3 is effective in the management of primary hepatocarcinoma, with a significant analgesic effect. To some extent, it can extend TTP and MST in advanced liver cancer patients, while the treatment is well tolerated in the majority of patients.
