Electrical status epilepticus during sleep(ESES)is a special electroencephalography in children.It is involved in a variety of epileptic syndromes and can lead to different degrees of degradation of movement, cognition, behavior, language.At present, the cause of ESES is still unknown.According to literature reports, 8 pathogenic genes have been found to be related to ESES, namely GRIN2A, CNKSR2, SCN2A, KCNA2, KCNQ2, KCNB1, SLC6A1 and WAC genes.In this review, progress of ESES molecular genetics are discussed.

Objective To study the therapeutic efficacy of Chinese botulinum toxin type A (CBTX- A) in masticatory spasm patients.Methods 16 patients with masticatory spasm were treated with CBTX-A local injection.12 patients showed jaw clench with masseter and temporalis affected (type Ⅰ).Four showed jaw clench and deviation to one side with pterygoid muscle affected unilaterally or bilaterally (type Ⅱ).All patients showed paroxysmal clenched jaw with difficulty in opening their mouths.There were no other clinical manifestations.CT and MRI did not reveal any intracerebral abnormalities.The efficacy and adverse effects were observed.Results CBTX-A were injected into 16 patients,resulting in a significant improvement of symptoms in 13 cases (4 cases of unilateral type Ⅰ,7 of 8 cases bilateral type Ⅰ,2 of 4 type Ⅱ).The spasms ceased within 3-10 days after the injection,and the effects lasted for 8-26 weeks.Four patients were observed to have slight masseter weakness after the injections,which recovered within a few weeks.The benefit persisted after identical repeated injection.Conclusion CBTX-A injection is an effective and safe treatment for masticatory spasm.

AIM:To explore the regulatory effect of microRNA-3666 (miR-3666) on the expression of its tar-get gene phosphatase and tensin homologue deleted on chromosome ten (PTEN) in leukemic cells.METHODS: miR-3666 expression levels in normal peripheral blood mononuclear cells and leukemic cells were determined by quantitative real-time PCR.miR-3666 targeting PTEN 3'-untranslated region (3'UTR) was predicted by TargetScan software .3'UTR of PTEN was inserted in the dual luciferase reporter vector psiCHECK 2.The reporter activity was evaluated by the Dual-Lu-ciferase Reporter Assay System after the luciferase promoter vector and miRNA were co -transfected into HEK293T cell line. K562 cells were transfected with synthetic miR-3666 inhibitor ( anti-miR-3666) or a synthetic control miRNA ( anti-miR-C) .The expression of PTEN protein in the above transfected K 562 cells was determined by Western blotting .RESULTS:miR-3666 was up-regulated in the human leukemic cell lines and primary leukemic cells compared to normal peripheral blood mononuclear cells .The results of dual luciferase assays validated PTEN as a specific target gene of miR-3666.Inhi-bition of miR-3666 resulted in an up-regulation of PTEN protein expression in the K 562 cells.CONCLUSION:miR-3666 is over-expressed in leukemic cells .The abnormal over-expression of miR-3666 may play a key role in leukemia due to the down-regulation of PTEN .

ObjectiveTo compare three types of acute Mycobacterium tuberculosis infection mouse models established through different infection routes and to set up the theoretical basis for further developing,selecting and applying these animal model in the tuberculosis-related research.MethodsStandard strain of Tubercle bacillus H37Rv was diluted to 1 × 106 colony forming unit (cfu)/mL.The mice were infected with the bacteria through different routes including intravenous injection,intranasal administration and inhalation of bacteria aerosol.Six weeks after the infection,the mice were euthaniz ed and necropsied. The lung tissues were collected and gross changes were observed.The colony counting was performed and the lung tissues were assessed by HE staining,acid fast staining.The e xpression level of tumor necrosis factor (TNF)-α per unit area in lung tissue was detected by immunohistochemistry. The data were analyzed by t test. Results The amounts of Mycobacterium tuberculosis in lung tissues of mice in inhalation group,intranasal administration group and intravenous injection group were (6.290±0.028),(6.150±0.021) and (6.120±0.008) lg cfu/mL,respectively; while no Mycobacterium tuberculosis was detected in control group. The difference between infection group and control group was statistically significant (t =3.762,P＜0.01),while there were no significant differences among infection groups with different infection routes (P＞0.05).According to the results of gross observations and histological assessment,the pathological changes were observed and red tubercle bacillus was detected by acid-fast staining in the lung tissues of all the mice in infection group.The results of immunohistochemistry showed that the expression levels of TNF-α per unit area were as follows:intravenous injection group (0.049 × 106 )＜intranasal administration group(0.759×106) ＜ inhalationgroup(1.042×106), whichwere statistically different (t =2.504,P＜ 0.05).ConclusionInhalation of bacteria aerosol may be the most efficient method to establish tuberculosis infection mouse model compared to intravenous injection and intranasal administration.

BACKGROUND: According to the thought "prevention of diseases", a conception of "strengthening the vital by acupuncture preconditioning (AP)" is suggested recently.OBJECTIVE: To investigate the effect of brain tissue extract after AP on cerebral ischemia-reperfusion injury.DESIGN: Random control experiment.SETTING: Institute of Acupuncture & Moxibustion and Massage, and Department of Anatomy and Embryology, Hubei College of Traditional Chinese Medicine.MATERIALS: Totally 102 adult Wistar rats were selected during the experiment, which was completed in the Institute of Acupuncture & Moxibustion and Massage of Hubei College of Traditional Chinese Medicine from September 2003 to July 2004. Among them, 20 rats were used to prepare cerebral tissue extract, and another 82 were used in the subsequent experiment.METHODS: The brain tissue extract was obtained from the rats which were given electroacupuncture at Shenshu (BL-23) and Baihui (DU-20).Totally 82 rats were randomly divided into 6 groups. Five rats in blank control group were taken as blank control, 15 in sham-operation control group were performed with sham operation, 16 in cerebral ischemia-reperfusion control group with cerebral ischemia-reperfusion, 16 in saline control group with the injection of saline intravenously firstly and then cerebral ischemia-reperfusion modeling, 15 in normal cerebral tissue extract control group with the injection of normal cerebral tissue extract intravenously firstly and then cerebral ischemia-reperfusion modeling, and 15 in AP cerebral tissue extract group with the injection of cerebral tissue extract intravenously firstly and then cerebral ischemia-reperfusion modeling.Intravenous injection was performed 2 hours and 1 hour before cerebral ischemic modeling, and each rat was injected twice with 1 mL/time. Brain tissue of the rats was taken ont 1, 3, 7 days after reperfusion respectively (or each group was divided into 3 subgroups with 5 rats in each) except those in blank control group. The blain tissue of rat in each group was selected at the relevant time points, and embedded with paraffin and cut into pieces. Cerebral histopathology was observed under the light scope (× 400)and the survival neurons were counted whose area was layer y of region Ⅰ in parietal cortex (inner cone).cortex.RESULTS: Two rats died during the experiment in cerebral ischemiareperfusion control group and saline control group respectively. Another Except blank control group and sham operation group, the brain sections of different time points in other groups showed scattering ischemic anoxic Count of survival neurons in layer Ⅴ of area I in parietal cortex: One day after reperfusion, survival nerve density of the brain ischemic reperfusion model group [(338.8±31.2)/mm2] was significantly lower than that of blank control group [(753.4±60.8)/mm2] (F=129.36, P ＜ 0.05); degeneration of the nerves became worse after reperfusion for 3 days and 7 days, but with no significant difference (F=1.76, P ＞ 0.05). There was no significant difference between the saline control group, normal brain tissue extract group and brain ischemic reperfusion model group at different time points (F=1.76, P ＞ 0.05). Survival neuron density in group of brain tissue extract after AP at the three time points was significantly higher than that in brain ischemic reperfusion model group [(438.1±41.0), (338.8±31.2)/mm2,(296.4±27.1), (124.8±13.4)/mm2; (269.5±30.4), (1.324±0.157)/mm2;F=129.36, P ＜ 0.05].CONCLUSION: Injection of the brain tissue extract after AP at Shenshu (BL-23) and Baihui (DU-20) into the celiac cavity of rats could obviously reduce the subsequent neuron loss induced by brain isehemia-reperfusion and protect brain from ischemia-reperfusion injury.
