ObjectiveTo explore the relationship between the changes of neuro-electrophysiology and prognosis in children with Guillain-Barr? syndrome(GBS).MethodsThirty-eight children with GBS were divided into group A(rapid recovery,n=16) and group B(slow recovery,n=22) according to the time required for podosoma motor function recovery,at the same time,they were divided into the better prognosis group(n=22) and the worse prognosis group(n=16),for analyzing the difference between group A and B in terms of age,preceding infections,maximal Hughes grades and neuro-electrophysiology including motor conduction velocity(MCV),distal complex muscle action potential(dCMAP) and F wave,and investigating the related factors with the prognosis of GBS.Results1.MCV of tibial nerve was(40.2?2.53) m/s and(33.4?2.46) m/s in group A and group B,respectively;MCV of peroneal nerve was(45.2?3.23) m/s and(38.3?2.16) m/s in group A and group B,respectively,and the difference between group A and group B was significant(Pa0.05);abnormal rate of F wave(68.42%) was higher than abnormal rate of MCV(42.11%) and dCMAP(42.11%)(Pa

0.05).3.Thirty-three point three percent of animals from parental strain group were found fibrillations potentials and the po-sitive sharp waves in gastrocnemius electromyogram,no obvious abnormal waves were found in animals from both waaF mutant and control group.Conclusions The ganglioside-like epitope in LOS of CJ is critical antigen in inducing GM1-IgG antibody and in inducing conduction block of peripheral nerve,therefore,provide a support for the molecular mimicry theory as a pathogenesis in the axonal GBS following CJ infection.

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

Objective To summarize the clinical characteristics and diagnosis of hemiconvulsion-hemiplegia-epilepsy(HHE) syndrome.Methods The clinical data of 5 children with HHE syndrome were analyzed.Cranial magnetic resonance imaging MRI and /or computerized tomography(CT) and electroencephalogram(EEG) were done in all patients.Results The age of onset was less than 4 years in 4 of 5 patients and initial seizures were associated with fever in 3 cases.The longest duration of convulsive seizures lasted more than 2 hours in all cases,followed by the appearance of hemiplegia involving the side of the body where the convulsions were localized.Subsequent epilepsy developed within 2 years of the hemiplegia in all 5 cases,with 4 cases simple partial seizure and 1 case psychomotor seizures.All cases had mental retardation.Cranial MRI showed left hippocampal sclerosis in 4 patients and CT brain scan showed right cerebral hemiatrophy in 1 case.The EEG showed abnormality in all patients.Epileptiform discharges were found in 4 cases,and the damage hemisphere showed slowing and low voltage of background activity in 1 case.All cases received mainly carbamazepine therapy,and the seizures were satisfactorily controlled or partly controlled.Conclusions HHE syndrome is recognized as hemiplegia-epilepsy syndrome after prolonged hemiconvulsion.The hippocampal sclerosis may be the consequence of repeated seizures,but not the cause.Better understanding of the syndrome,early and adequate treatment of prolonged seizures,especially of febrile convulsion,will reduce the incidence of HHE syndrome.

Objective To report the outcome of emergency repair traumatized limbs by vascularized free tissue transplantation.Methods From April 1988 to August 2004,86 patients,58 men and 28 women,had undergone emergency vascularized free tissue transplantation to have their injured limbs repaired in 54 cases and the missing thumbs reconstructed in 32.The patients aged from 5 to 55 (mean 27.9) years. The transplants included latissimus dorsi myocutaneons flap,anterolateral femoral skin flap,medial crural skin flaps,dorsal pedal flaps,medial plantar flap,composite tissue mass of the discarded limbs and big toe skin- nail flap.The operations were performed 1 to 5 days after injuries.Results Postoperative vascular crises occurred in 8 cases and were all followed by exploration with successes in 5 cases while failure in 3.The total survival rate of the transplants was 96.5% (83/86).In this series all the patients were followed up for 1 to 16 years with a mean of 7.5 years only to reveal satisfying functional recovery in all the repaired limbs and an ex- cellent and good rate of 87.5% in the reconstructed thumbs.Conclusion Emergency vascularized free tis- sue transplantation is an effective way to repair a traumatized limb and to reconstruct a traumatically missing thumb.

Fifty-six patients with Graves' ophthalmopathy(GO)were treated with antithyroid drug and oral prednisone for three months,TSH receptor antibody(TRAb)level was reduced,GO activity and severity of some patients were ameliorated but still positively associated with TRAb.It suggests that TRAb not only triggers off GO but also plays a possible role in the maintenance of the autoimmune process in GO.

OBJECTIVETo study and compare the clinical and electroencephalography (EEG) features in children with benign occipital epilepsy (BOE) of Gastaut and Panayiotopoulos types.

METHODSThe clinical data of 23 children with BOE (16 Gastaut type and 7 Panayiotopoulos type) were retrospectively studied.

RESULTSThe mean age of onset in the Panayiotopoulos and Gastaut groups were 4.5 and 9.1 years, respectively. The children in the Panayiotopoulos group were characterized by ictal vomiting, frequent deviation of eyes and head, frequent nocturnal seizures, and secondary generalized seizures with longer duration but less frequency. By comparison, the children in the Gastaut group were characterized by visual symptoms as ictal events, higher seizure frequency, shorter seizure duration and more frequent diurnal seizures. The EEG showed that the majority of both groups had occipital spike-wave discharges when the eyes were opened. Eleven children in the Panayiotopoulos group and all of 7 children in the Gastaut group received antiepileptic mono-drug therapy. All of the 11 children in the Panayiotopoulos group responded to the therapy, but 2 cases in the Gastaut group did not respond and 2 cases had subtle cognitive deficits.

CONCLUSIONSThere are differences in the age of onset, clinical symptoms, seizure frequency and duration, and therapeutic responses between children with Panayiotopoulos and Gastaut type BOE.

AIMIn order to investigate the effect of mesenchymal stem/progenitor cells on proliferation and differentiation towards megakaryocytes of CD34+ cells from human umbilical cord blood in vitro.

METHODSAfter mesenchymal stem/progenitor cells were advancely planted in DMEM medium and grown up to 80%, then the CD34+ cells were added to culture with mesenchymal stem/ progenitor cells or without mesenchymal stem/progenitor cells in DMEM for 14 days with TPO + IL-3 + SCF, TPO + IL-3 + SCF + IL-11 respectively. After cultured for 14 days, mononuclear cells (MNCs) were counted by automatic cell analyzer. The number of CD41+ cells and platelets were detected by flow cytometry. Platelets function were assessed through platelet aggregation test which was induced by thrombin.

RESULTSAs compared with the control group, the number of MNCs of co-culture system was not increased significantly (P > 0.05), but the number of CD4+ cells and platelets were increased significantly (P < 0.05). The platelets were aggregated by thrombin induced which could be seen in microscope or flow cytometry.

CONCLUSIONIt is concluded that mesenchymal stem/progenitor cells may be promoted to induce the cord blood CD34+ cells to differentiate towards megakaryocyte in the culture medium.
