Objective To explore the effect of repetitive transcranial magnetic stimulation (rTMS) on motor function in cerebral palsy children with epilepsy. Methods 270 cerebral palsy children with epilepsy hospitalized from February, 2011 to September, 2014 were ran-domized to control group (n=130) and treatment group (n=140). The control group received comprehensive rehabilitation, including mas-sage, exercise, occupational therapy, physiotherapy, speech training, cognitive function training and medication, and the treatment group re-ceived rTMS in addition. They were assessed with Gross Motor Function Measure-88 (GMFM-88) and Peabody Developmental Measure Scale-Gross Motor (PDMS-GM) before, and 1 and 2 months after treatment. Results The total scores of GMFM-88 and PDMS-GM in-creased more in the treatment group than in the control group (F>93.9, P<0.001). Conclusion rTMS can further improve the motor function in cerebral palsy children with epilepsy.

Results Total effective rate and curative rate of SIT group were 93.2% and 68.9% respectively, and those of control group were 68.9% and 17.6% respectively, which had a significant difference between the two groups(P

Surgical resection is the treatment of choice for patients with colorectal liver metastases.The criteria for hepatic resection of colorectal liver metastases have been extended.Patients who were expected to have complete tumor resection,negative resection margin and adequate remnant liver volume could receive surgical resection.Surgical resection combined with local ablation can expand the resectability of liver metastases.There is no significant difference of long-term survival between simultaneous and staged resection for colorectal and liver tumors.Laparoscopic surgery has been proved as safe and feasible for colorectal liver metastases.The survival benefits of adjuvant chemotherapy during perioperative period is unclear,and neo-adjuvant chemotherapy might not benefit all the patients with colorectal liver metastases.

Objective To investigate the MRI manifestations of cerebral glioma involving corpus callosum,and to enhance the ability to diagnosis and differential diagnosis.Methods Thirty four cases of cerebral glioma involving corpus callosum under went plain and Gd DTPA enhanced MR scans.The MRi findings of these gliomas were compared with operation and pathology.Results Gerebral gliomas involving corpus callosum presented as long T 1 and long T 2 homogeneous or inhomogeneous signal intensity and obvious mass effect.The MRI findings of Gd DTPA enhanced MR scans were obvious enhancement,slight enhancement or no enhancement accouding to different pathological kinds of gliomas."Butterfly signs" and "semi butterfly signs" were the reflections when gliomas of corpus callosum invaded two sides or one side of cerebral hemisphere.These two signs were significant markings in the diagnosis of cerebral gliomas in corpus callosum region.Conclusions Cerebral gliomas involving corpus callosum are intracranial tumors with special location.MRI has significant clinical value in the diagnosis and differential diagnosis of this kinds of tumour.

Aim Toinvestigatetheeffectofhigh,me-dium and low doses of Mahuang decoction on the re-lease amount of rat hippocampal neural transmitter (Glu,Gly,Asp,GABA),then compare Mahuang de-contion with ephedra alkaloids and ephedra.Methods Ratswererandomlydividedinto6groupsandgiven orally with Mahuang decoction of high dose (calculated by ephedra 4 g·kg-1 ),medium dose (calculated by ephedra 2 g·kg-1 ),low dose (calculated by ephedra 1 g · kg-1 ),ephedra (calculated by ephedra 2 g · kg-1 ),ephedra alkaloids (ephedrine 7 mg · kg-1 , pseudoephedrine 2. 4 mg · kg-1 , methylephedrine 1. 12 mg · kg-1 )and blank control group.Samples were obtained from the hippocampus of conscious rat by microdialysis sampling technique.The content of ami-no acid neurotransmitters in dialysates was detected u-sing the established HPLC-ECD with OPA pre-column derivationmethod.Results Fouraminoacidneuro-transmitters could be well separated in 28 min.High, medium and low doses of Mahuang decoction,ephedra and ephedra alkaloids significantly increased the con-tent of these four amino acid neurotransmitters,com-pared with blank control group (P<0. 05 ).Ephedra alkaloids significantly reduced the levels of inhibitoryamino acid neurotransmitters GABA and Gly in 90 min,compared with the medium dose of Mahuang de-coction.Excitatory neurotransmitters of ASP and Glu in hippocampus showed the trend of increase first and then decrease after oral administration of Mahuang de-coction and ephedra. The levels of Glu and Asp reached peaks from 90 min to 120 min after treatment with Mahuang decoction,and also increased along with dose increase of Mahuang decoction.In comparison with the medium dose of Mahuang decoction group,the level of Glu reached peak at 90 min and 150 min in ephedra alkaloids group and ephedra group respective-ly,and the content of Glu significantly increased at peaktime.Conclusions Increasedcontentofexcita-tory amino acid neurotransmitters (Asp and Glu ) shows positive correlation with the dose of Mahuang de-coction.Other components in Mahuang decoction in-hibits the up-regulation effect of ephedra and ephedra alkaloids on Glu,and promotes the up-regulation effect of ephedra alkaloids on GABA and Gly.

OBJECTIVEThis study aimed to evaluate the morphometric changes in the alveolar bone of the maxillary and mandibular anterior regions after retraction in adolescents.

METHODSThe sample size comprised 30 adolescent patients with class 1 bimaxillary protrusion (12 males and 18 females, age: 12-18 years old) and were treated by extracting four first pre-molars. Cone beam computed tomography (CBCT) was performed 1 month before and 1 month after the retraction. For each maxillary and mandibular anterior tooth, the labial and palatal alveolar plates at cervical 1/3, middle 1/3, and apical 1/3 levels for bone thickness changes during the retraction of the maxillary and mandibular anterior regions were checked. The movements of cervical 1/3, middle 1/3, and apical 1/3 levels of the maxillary central incisor were measured. Statistical analyses were performed with SPSS 16.0.

RESULTSFor the adolescents, alveolar bone thickness increased on the labial side and decreased on the palatal side. The alveolar bone thicknesses of cervical 1/3 and middle 1/3 of maxillary central incisor, cervical 1/3 and apical 1/3 of maxillary lateral incisor, middle 1/3 of mandibular central incisor, apical 1/3 of mandibular lateral incisor, and middle 1/3 and apical 1/3 of mandibular canine all increased after retraction. By contrast, the alveolar bone thickness of the apical 1/3 of maxillary canine and the cervical 1/3 of mandibular canine decreased after retraction. No statistically significant difference was observed in other region.

CONCLUSIONDuring retraction, a controlled tipping movement occur in adolescents. After retraction, the alveolar bone thickness of the labial side increase, whereas that of the palatal side decrease. Moreover, the thicknesses of major areas in the alveolar bone significantly increase.

AIM　To study the effects of Aβ25～35 and Apo E4 on neuronal intracellular free Ca2+(［Ca2+］i). METHODS　Hippocampal and cortical neurons suspension of newborn(0～3 days) SD rats was produced. After incubated with fura-2/AM,the neurons suspension was divided into four groups: control, Aβ25～35, Apo E4, Aβ25～35+Apo E4. Each groups ［Ca2+］i was measured using a RF-5000 dual wavelength spectrofluorometer after incubated with double distilled water, Aβ25～35, Apo E4, Aβ25～35+Apo E4 for 3 min, respectively. The neurons outocorrelation function(ACF) of the scattering light intersity was analyzed by the microscope quasi-elastic light scattering(MQLS) technique The frequency shift line width by ACF. The Γ can sympolize the cell menbrane flilidity. RESULTS　Both Aβ25～35 and Apo E4 could significantly enhance hippocampal and cortical neurons rest ［Ca2+］i, furthermore, the effect of 5 μmol*L-1 Aβ25～35 was higher than the effect of 1 μmol*L-1 Aβ25～35 (P<0.05), and they also amplified KCl-induced rise in ［Ca2+］i in hippocampal and cortical neurons(P<0.05). The interaction of Aβ25～35 and Apo E4 could also significantly enhance hippocampal and cortical neurons rest ［Ca2+］i andamplified KCl-induced rise in ［Ca2+］i in hippocampal and cortical neurons(P<0.05), but they had no synergic or additive effect.The frequency shift line widith Γ of both hippocampal and cortical neurons were decreased by both Aβ25-35 and ApoE4. CONCLUSION　Aβ25～35 and Apo E4 could enhance neuronal intracellular free Ca2+, amd decrease meirpma; ,e,brame f;iodotu. But their interaction had no synergic or additive effect. It suggested that the amplified effect of Aβ25～35 and Apo E4 on neuronal ［Ca2+］i and membane fluidity may be relative to their neurotoxity.
