Objective To explore the significance of multiple microelectrode guided technique in determining the sensory?motor area of the sub?thalamic nucleus(STN)in deep brain stimulation(DBS)surgeries. Methods A total of 22 electrophysiological recording data of STNs recorded by multiple microelectrode was retrospectively analyzed ,while another 20 electrophysiological recording data of STNs recorded by a single micro?electrode was recruited as the control group. Results A total of 64 microelectrodes were used in 22 STNs guided by multiple electrophysiological recording electrodes. Sensory or motor activated potentials were recorded in 21 sides(95.5%),while regular discharge was recorded in one side. The average length of typical STN activity on the optimal channel of multiple electrophysiological recording electrodes was 5.58±0.53 mm,and the average length of sensory or motor activated potentials was 3.27±1.54 mm. In contrast,the average length of typical STN activity recorded by single microelectrode was 5.02±1.01 mm. However,sensory or motor activated potentials were recorded in 13 sides(65.0%)with the average length of 1.36±0.98 mm. Among the 22 STNs guided by multiple electrophysiological recording electrodes,the final implanted target was consistent with the initially selected anatomic target in 13 sides(coincidence rate,59.1%). In 9 sides,the electrophysiological target was inconsistent with the initially selected anatomic target. Conclusion STN DBS performed with multiple electrophysiological recording electrodes resulted in better outcomes of recording of the average length of typical STN activity or the average length of sensory or motor activated potentials of STN ,final confirmation of STN sensory motor area and determination of the optimal channel of implantation. Application of multiple electrophysiological recording electrodes provides a premise for the precise electrode placement in STN DBS surgeries.

Objective To determine main factors associated with quality of life in epileptics in northen China especially seizure severity and stigma, and the variations between men and women. Methods All patients with epilepsy aged 18-65 years were selected from the First Affiliated Hospital of China Medical University, tested from March 2014 to March 2015. All of them completed the general social science data, the Quality of Life Inventory in Epilepsy-31 (QOLIE-31), Liverpool Adverse Events Profile (LEAP), the National Hospital Seizure Severity Scale (NHS3), Epilepsy Stigma Scale (ESS), Self-rating Anxiety Scale ( SAS) and Hamilton Depression Scale ( HAMD) assessment. Results A total of 123 patients with epilepsy (60 men, 63 women) were interviewed. QOLIE-31 scores were 55. 81 ± 10. 17 in female patients, 65. 35 ± 10. 89 in male patients, the difference being statistically significant (t=2. 90, P<0. 05). ESS (1(0,2)), SAS(31. 85 ± 8. 16), HAMD (4. 38 ± 2. 90) scores of female patients were higher than that of male patients (0(0,0), 26. 93 ± 3. 45, 2. 80 ± 1. 39;U= -2. 710, t=2. 48, 2. 20, all P<0. 05). Multiple factors analysis and multiple stepwise regression analysis on quality of life revealed that depression (β= -0. 516, P<0. 01) and the severity of epilepsy (β= -0. 338, P=0. 01) were two strong predictors of QOLIE-31 overall scores. The linear regression showed that there was a direct link between shame and degree of depression (β = 0. 515, P= 0. 001 ) . Conclusions The main factors affecting the quality of life in epileptics in northen China are depression and seizure severity. Compared with male patients, female patients have a lower quality of life, and poorer psychological status, such as shame, depression and anxiety. There is a direct link between shame and depression in epileptics.

The distribution of the ACTH_(1-39)-immunoreactive neurons in the hypotha- lamus of 4 human adults was examined with ABC immunocytochemical method. The results showed that in addition to ACTH_(1-39)-immunoreactive neurons found in the infundibular nucleus of the hypothalamus which were identical with the previous reports, negafivt ACTH_(1-39)immunoreactive neurons were also found in paraventricular and supraoptic nuclei. These cell bodies were round or elliptic in shape. More negative ACTH_(1-39)immunoreactive fibers were seen in the periventricular layer, paraventricular nucleus and dorsal area of supraoptic nucleus.

Objective To investigate the effect of augmenter of 1iver regeneration(ALR)on hepatocytes transplanted intraperitoneally in acute hepatic failure(AHF)rats.Methods AHF SD rats were induced by D-gal.The rats were divided into 5 groups randomly:blank control group(only receiving normal saline),transplantation control group(transplanting 2 X 107 hepatocytes from SD rats),ciclosporin A group(CsA group,receiving hepatocytes and CsA 6 days after transplantation),ALRgroup(receiving hepatocytes plus ALR 6 days after transplantation),ALR control group(only receiving ALR 6 days after transplantation).All drugs and cells were intraperitoneally injected.There was a observation period of 14 days after transplantation.The survival rate of receptors and transplanted hepatocytes was observed.The expression levels of CD4,CD8 and CD68 in abdominal cells,the levels of IL-1β and TNF-a in serum and douche of peritoneal cavity were detected.Results The 2-week SuFvival rate in blank control group,transplantation control group,CsA group,ALR group and ALR control group was 0,46.7%,20%,66.7%and 14.3%respectively.Survival rate in AI.R group was higher than in blank control group(P=0.001).Serum levels of d1-2 TNF-a in ALR group was all lower than in blank and transplantation control groups(P＜(0.01).Serum levels of d1-2 IL-18 in ALR group were lower than in transplantation control group.Ascitic levels of d1-2 TNF-a and IL-1β in transplantation control group were higher than in other groups(P＜0.05,P＜0.01).The serum levels of TNF-a and IL-1β in all survival groups were similar tO normal levels on the 14th day after transplantation.The positive expression rate of d1-2 CD68 in grafts of ALR group was(0.5±0.3)%.The positive expression rate of CD68 in grafts of ALR group was obviously lower than in transplantation control group and CsA groups(P＜0.01).The expression of d1-2 CD68,CD4 and CD8 in ALR group was respectively(1.3±1.2)%,(0.1±0.3)%and(0.2±0.1)%,all obviously lower than in transplantation control group(P＜0.01,P＜0.01,P＜0.05).Assembled conglobate hepatocyte noduses were observed in abdominal cavity in rats receiving hepatocytes transplantation during first to third day after transplantation.The number of survival grafts in ALR group was more than that in transplantation control group and CsA group,and infihrated inflammatory cells were less.On the 14th day posttransplantation.small amounts of normal hepatocytes in grafts were observed only in ALR group.Conclusion After HcT plus ALR intraperitoneally,the survival rate of AHF rats was increased.ALR improved survivorship of transplanted hepatocytes in short term.

Objective To explore the mechanism of spontaneous seizures in adaptor protein complex type 3B knockout mice(AP3M2KO mice).Methods AP3M2KO mice were generated.Seizures and electroencephalogram(EEG)were monitored using video camera and telemetry system.Glutamate and GABA releases were determined using in vivo microdialysis method.Results AP3M2KO mice began to suffer from spontaneous seizures 8 weeks after the birth,but did not show any other behavior abnormality.The onset of ictal discharge over the temporal region was synchronized with seizures.There were no significant differences in basal glutamate and GABA releases in hippocampus between AP3M2KO((0.35±0.08)pmol/20μl and(2.94±1.69)fmol/20μl,respectively)and wild-type mice.However,the 50 mmol/L K+-evoked GABA release was impaired in AP3M2KO mice((63.5±11.8)fmol/20μl vs(209.2±63.7)fmol/20 μl,t=4.405,P＜0.05),whereas no significant difference was found in K+-evoked glutamate release.Conclusions AP3M2KO mice suffer from epileptic seizures similar to the clinical features of human epilepsy.The impairment of inhibitory GABAergic transmission iS involved in the mechanism of spontaneous seizures in AP3M2KO mice.
