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.

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 effects of specific immunotheraphy(SIT) using allergens for children atopic dermatitis(AD) to find an efficacious method to treat AD. Methods 148 children with AD were divided into SIT group and control group. All patients were given allergen intradermal tests. The patients in SIT group received SIT using positive aero-allergens for 8 to 18 months. The patients in control group received the treatment of antihistamine drugs and drugs for external use. 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

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.

Objective To explore the dose and effects of mixtures of pethidine and haloperidol for Postoperative Deliri-um. Methods Retrospective analysis was conducted on treatment dose and effects of 85 cases of patients with deliri-um during narcotic awake period or 1 day to 2 days after operation by mixtures (haloperidol with pethidine) from 2005 to 2006 in Affiliated Hospital of Hainan Medical College. Results 1/4 dose of mixture (pethidine 100 mg and haloperidol 5 mg) cured 9 patients, 1/2 dose of mixture cured 61 cases, we add 1/4 dose of mixture when 10 cases occurred delirium again ,5 cases added 1/2 dose of mixture again, all were cured. After administration ,aublood pres-sure declined all, but all were within normal range, the 17 cases's pulse oxygen saturation is less than 95%, Conclu-sion The mixture (haloperidol with pethidine) can be effective treatment for delirium during awake period of general anesthesia or after operation. However, application of low dose therapy from the beginning, and attention to its impact on respiration.

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.
