Objective To quantify the effect of gradual respiratory functional training on the lung function and quality of life (QOL) of patients convalescing from Guillain-Barré syndrome (GBS). Methods Thirty-two GBS patients were randomly divided into two groups a control group which received routine nursing and a respiratory function training group.The training was in three stages:thoracic or/and abdominal respiration,deep breathing and respiratory exercise.After 2 and 4 months of treatment,the 16 min walk test and the SF-36 health questionnaire were used to evaluate the subjects' lung function,motor capacity and QOL. Results After 2 and 4 months of treatment,vital capacity (VC),forced vital capacity (FVC),forced expiratory volume in one second (FEV1) and maximal ventilatory volume (MVV) had all improved significantly in the training group.Their 6 min walk distances and QOL ( in all 8 domains) had also improved significantly.The average VC.FVC.FEV1 and MVV in the control group all decreased slightly but the decreases were not significant.Their 6 min walk distances had improved significantly,however,as had the physical function,mental health.psychological role,physical pain and integrated health domains of their QOL. Conclusion Training the respiratory functional of GBS patients during convalescence can prevent the lung function decay due to muscle weakness,and can also improve motor ability and QOL.

Objective To explore the changes of rabbit adipose stem cells(ASCs)and bone mesenchymal stem cells(BMSCs)cultured in vitro and the anabolism under basic fibroblast growth factor(bFGF).Methods BMSCs and ASCs were cultured with DMEM,DMEM/F12(2∶1)or α-MEM respectively.The 3rd generation ASCs and BMSCs were divided into 2 groups respectively:group A:ASCs cultured in chondrogenic medium(CM),group B:ASCs cultured in CM supplemented with bFGF 5 ng/ml,group C:BMSCs cultured in CM,group D:BMSCs cultured in CM supplemented with bFGF 5 ng/ml.Morphological changes were observed under inverted microscope.The 35SO42-incorporation and total hydroxyproline were measured.Results BMSCs and ASCs showed much higher growth rate when cultured in α-MEM medium comparison with that in DMEM or in DMEM/F12(2:1).Both stem cells attachment cultured in monolayer greatly increased and cell clones were abundant,while the cells attachment became rather difficult and cell clones were less after cutured in CM.All stem cells possessed a round-like morphology,and the cells in group B and D were more than that in the other 2 groups.The 35SO42-incorporation and total hydroxyproline synthesis of group B or D increased compared with that of group A or C,but there was no diference between group D and B.Conclusion The rabbit ASCs and BMSCs cultured in CM suppling with bFGF grow well and their metabolism increased.

Objective To investigate the risk factors of reversible posterior leukoencephalopathy syndrome (RPLS) in pre-eclampsia or eclampsia gravida. Methods This study was conducted in the Third Affiliated Hospital of Guangzhou Medical University between January 2013 and March 2016. A total of 100 patients who had no severe neurological diseases and were diagnosed pre-eclampsia or eclampsia, and underwent brain MRI were collected retrospectively. They were divided into 2 groups according to the MRI results, the RPLS group (n=49) and the non-RPLS group (n=51). The medical history, clinical symptoms and the results of laboratory examination were analyzed by the logistic regression, in order to explore the risk factors.Results In single factor analysis, HELLP syndrome, pregnancy associated with other diseases, poor prenatal care, grade 3 hypertension, elevated systolic blood pressure or diastolic blood pressure, elevated WBC, aspartate transaminase (AST), alanine aminotransferase (ALT), uric acid (UA) and lactate dehydrogenase (LDH), decreased platelet (PLT), headache, visual changes, seizures and conscious disturbance were more frequent in the RPLS group than those in the non-RPLS group (all P<0.05). According to the multivariate logistic regression analysis, the elevated WBC (OR=1.291, 95%CI:1.058-1.575, P=0.012), UA (OR=1.008,95%CI:1.001-1.016,P=0.032) and headache (OR=18.260, 95%CI:3.562- 93.607, P=0.000) were the independent risk factors.Conclusions Maternal history, clinical symptoms and some laboratory examinations might help in the early diagnosis of RPLS in pre-eclampsia or eclampsia gravida. Headache, the elevation of WBC and UA were the most significant factors.

OBJECTIVETo analyze the clinical characteristics of pediatric neuromyelitis optica (NMO) and neuromyelitis optica spectrum disorders (NMOSD).

METHODA retrospective analysis was performed evaluating clinical and laboratory characteristics of ten NMO and NMOSD children who were seen in our hospital from December 2010 to May 2014. Median age at onset was 8.9 years (range 0.8-13.8 years). Seven cases were female and three were male. Median disease duration was 1.5 months (range 1-18.5 months).

RESULTEight patients fulfilled diagnostic criteria for NMO and two patients fulfilled diagnostic criteria for NMOSD. The two NMOSD patients had recurrent longitudinally extensive transverse myelitis. Four cases had a monophasic disease course, and six cases had a recurrent course. In eight NMO patients, neuritis was the initial presentation. The two NMOSD patients had no neuritis in the first attack. Nine cases had clinical manifestations of myelitis, one case had asymptomatic spinal cord MRI anomaly. Among the ten patients, seven cases had brain lesions, wherein, four cases had the midbrain involvement and in four cases extensive hemispheric white matter was involved. Three cases had medullary involvement. And two cases had posterior limb of the internal capsule involvement, two cases had thalamus involvement. In one case there was pons, cerebellum or corpus callosum involvement, respectively. One case had accompanied brain symptoms. Of the five patients who had symptomatic brain lesions, four cases had encephalopathy accompanied by large hemispheric lesions on MRI, having a presentation similar to acute disseminated encephalomyelitis. And one case had multiple sclerosis like brain lesion. Of the ten patients tested, nine were seropositive for anti-aquaporin-4 autoantibody. One-patient was complicated with systemic lupus erythematosus. Oligoclonal bands were negative in all cases. All patients received treatment for acute attacks with high-dose intravenous methylprednisolone and intravenous gammaglobulin. The symptoms of 8 cases mitigated. Two cases whose symptoms showed no sign of improvement received plasmapheresis for acute attacks. Seven of the patients were followed up. The median duration of follow-up was 19 months (ranged from 13 months to 30 months). The median Expanded disability status (EDSS) score was 3 (range 1-7).

CONCLUSIONPediatric NMO and(or) NMOSD have a diverse clinical presentation which are more than just optic neuritis and transverse myelitis, including brain symptom. So it may be difficult to distinguish NMO and( or) NMOSD from acute disseminating encephalomyelitis and multiple sclerosis in the early stages of the disease. Antibodies to aquapoin-4 (AQP-Ab) testing is very important for differential diagnosis.

By culturing bone marrow mesenchymal stem cells of rabbits with fibrin glue in vitro, the biocompatibility of fibrin glue was investigated to study whether this material can be used as scaffolds in bone tissue engineering. After 2-months old New Zealand rabbits had been anesthetized, about 4-6 ml of bone marrow were aspirated from rabbit femoral trochanter. The monocytes suspension was aspirated after bone marrow was centrifuged with lymphocyte separating medium and cultured primarily. Then the cells were divided into two groups: one was cultured with complete medium and the other with induced medium. The cells of the two groups were collected and inoculated to the culture plate containing fibrin glue. In the control group, cells were inoculated without fibrin glue. The implanted cells and materials were observed at different stages under a phase-contrast microscope and scanning electron microscope. MTT and alkaline phosphatase (ALP) were measured. Bone marrow mesenchymal stem cells grew on the surface of fibrin glue and adhered to it gradually. Cells light absorption value (A value) and the ALP content showed no significant difference. Fibrin glue had no inhibitory effect on cell morphology, growth, proliferation and differentiation. It has good biocompatibility and can be used as scaffold materials for bone marrow mesenchymal stem cells in bone tissue engineering.
