Conclusion The progressive rehabilitation exercise program developed from evidence-based practice is safe, effective and feasible.

Objective To develop a mobile application and to investigate the feasibility to support exercising in patients with chronic ob-structive pulmonary disease (COPD) in home. Methods TheCOPDmobile application include 6 function modules including exercising, exercising reminder, ranking, the basic knowledge of disease, exercising statistics and questionnaire collecting. 15 eligible patients with COPD were recruited in the outpatient departments of a tertiary hospital in Beijing by convenience sampling method from August to Decem-ber, 2015. They received Redmi 2a phones and were taught to use COPD application pre-installed in phones. They were asked to useCOPDapplication to support exercising at home for 1 month. Study outcomes included user satisfactions and exercising data. Results 14 (93.3%) patients thoughtCOPDapplications were helpful for exercising, 12 (80%) patients were satisfied withCOPDapplication. Some patients reported difficulty in manipulating smartphones and mobile applications. Some suggestions were put forward, such as, the stability and speed of data transmission should be improved and the sound of metronome should be increased. They exercised (44.6±8.4) minutes ev-ery day for (4.9±1.1) days per week in the latest 1 month. Conclusion Patients with COPD were highly satisfied withCOPDapplication.

Objective To explore the influence of positive psychological quality on the quality of life of rural left behind elderly. Meth-ods 356 rural left behind elderly in Bengbu and Huaibei cities of Anhui province were investigated with WHO Quality of Life-BREF (WHO-QOL-BREF), Chinese version of the Meaning in Life Questionnaire (C-MLQ), Purpose-in-Life Test (PIL) and Index of Well-Being (IWB). Results The scores of WHOQOL-BREF in physical, psychological, social relations and environment are significantly lower in the rural left behind elderly than in the norm in China (t>3.105, P<0.001). The scores of WHOQOL-BREF of the left behind elderly in rural areas signifi-cantly correlated with the sense of life meaning, life objective and subjective well being (P<0.05). The quality of life of left behind elderly in rural areas was analyzed by regression analysis, age, health status, education and other demographic variables and life goals, life sense, sense of autonomy, etc. entered the regression equation (P<0.05). The structure model analysis showed that the life meaning and purpose of life were the important factors that affected the quality of life of rural left behind old people, in which the subjective well-being played a meditational role. Conclusion The positive psychological quality of life meaning, life purpose and other positive psychological qualities sig-nificantly impact the quality of life of rural left behind elderly, and should carry out targeted mental health guidance.

A mixed lytic/sclerotic pattern of bone destruction was found in 11 cases, and the sclerotic type in 2 cases, the osteolytic type in 2 cases. Ra-dial periosteal reaction was found in 5 cases and immature bone formation in 8 cases. Soft tissue masses were seen in 13 cases. MRI showed enhancement in 15 cases and the CT showed no enhancement in 2 cases with sclerotic type. Conclusion The typical imaging manifestations of pelvic osteosarcomainclude mixed lytic/sclerotic appearance, radial periosteal reaction, soft tissue masses and immature bone formation.

Objective To explore the factors related to the outcome of idiopathic facial palsy. Methods 308 patients with idiopathic fa-cial palsy were included. The data of clinic and follow-up were collected from January, 2010 to December, 2014. The data were analyzed by Logistic regression analysis. Results 210 cases (68.2%) were cured (good group) and 98 cases (31.8%) appeared sequelae of different de-grees (poor group). The age, onset of disease, type of disease, damaged section, impaired glucose control, high neutrophil-to-lymphocyte ra-tio (NLR), high blood glucose, high blood triglyceride, time and methods of invention were significant factors related to the outcome (P<0.05). Conclusion Old, servious facial nerve injury, Hunt's palsy, high damaged section, poor glucose control in the patients with diabetes, high NLR, high blood triglyceride, delay and simple invention are independent risk factors for the poor outcome of idiopathic facial palsy.

Objective To explore the effect of Occupational Therapy in Group on cognitive function of children with March to cerebral palsy, and to observe the evaluation results of P300 of event-related potentials on cognitive function. Methods 40 children with spastic cere-bral palsy from March to September, 2015, were divided into control group (n=20) and observation group (n=20). Both groups received rou-tine rehabilitation training, and the observation group received Occupational Therapy in Group additionally, for 3 months. They were as-sessed with Wechsler Preschool and Primary Scale of Intelligence (WPPSI) and P300 of event-related potentials before and after treatment. Results The latency of P300 shortened after treatment (t>7.778, P<0.001), and the amplitude of P300 was larger after treatment (t>5.808, P<0.001) in both groups, especially in the observation group (t>0.461, P<0.05). The score of WPPSI increased after treatment in both groups (t>5.944, P<0.001), and was higher in the observation group than in the control group (t=-3.472, P=0.001). Conclusion Occupational Ther-apy in Group could further improve the cognitive function of children with spastic cerebral palsy. P300 can be used as an assessment tool for cognitive function.

Objective To analyze the metabolic profile of children with dyskinetic cerebral palsy by metabolomics, and its abnormal metabolic pathway. Methods The serum of 10 children with dyskinetic cerebral palsy (patient group) and 7 healthy children (control group) aged 6 to 12 years were collected at clinic from May to August, 2014. The serum samples were tested by the nuclear magnetic resonance spectrometer and the spectroscopies were discriminated by partial least squares-discriminant analysis. According to the human metabolome database, the final metabolites disturbed would be figured out. Results 15 chemical shifts were defined, and 6 of them, including 2.04 ppm, 2.12 ppm, 3.00 ppm, 3.24 ppm, 3.76 ppm, 6.50 ppm, were significantly different between 2 groups (P<0.05). The KEGG Pathway Database showed that the levels of taurine, fumarate, oxaloacete, pyruvate, citrate, aspartate, succinate, malate, cysteine decreased, and the levels of glutamate, 2-oxoglutarate, glutamine, leucine, alanine increased. The abnormal metabolism was found in taurine metabolism, glutamine me-tabolism and energy metabolism pathways. Conclusion Based on metabolomics, the metabolic profile of children with dyskinetic cerebral palsy was discriminated out successfully. The further research can focus on the small molecules found out.

Objective To study the relationship between injury site (right or left) or pathological type (hemorrhage or infarct) and atten-tion impairment in post stroke cognitive impairment (PSCI). Methods June, 2014 to June 2015, 49 patients with PSCI were assessed with Test of Attentional Performance (TAP) within 1 week of admission. The reaction time and the numbers of correct response were recorded. Results The reaction time of alertness (with or without alarm) was shorter in the patients with left infarction (Z=-2.32, t=-3.76, P<0.05), and the correct number of auditory was more (Z=2.42, P<0.05) than those with right infarction. The reaction time of incompatibility test and Go/Nogo test was shorter in patients with left hemorrhage than those with right hemorrhage (Z>2.32, t=-3.10, P<0.05). Conclusion A trend of lateralization was found in patients with PSCI, rather than in the pathology.

Objective To explore the expression of aquaporin (AQP)-4 in white matter of spinal cord after spinal cord contusion (SCC). Methods 88 adult Sprague-Dawley rats were assigned randomly to sham operation group and SCC group. The model was established by Al-len's method. BBB sore was used to assess the motor function of rats. The relative expression of AQP-4 mRNA was determined by Q-PCR technique. The localization of AQP-4 was observed by immunohistochemistry. Results BBB score showed motor dysfunction in SCC group, and it increased 7 and 14 days after SCC (t>5.061, P<0.001). The level of AQP-4 mRNA decreased on the 1st and 3rd days (t>50.44, P<0.001), and increased on the 5th day (t=-3.968, P=0.001), and lasted until the 28th day (t=-4.227, P=0.001) compared with that on the 3rd day. The immunohistochemistry showed AQP-4 was located on the process of glial cell and vascular endothelial cells in white matter of spi-nal cord. Conclusion AQP-4 may play various roles at different stages in SCC.

Objective To observe the effects of butylphthalide on the expression of autophagy-related protein and mRNA in l-meth-yl-4-phenyl-pyridiniumion (MPP+)-induced SH-SY5Y cells, and to explore the protective effect and possible mechanism of butylphthalide to the cell model of Parkinson's disease. Methods The SH-SY5Y cells were divided into control group (A), MPP+group (B), rapamycin pre-treated+MPP+group (C) and Butylphthalide pretreated+MPP+group (D). The relative viability of SH-SY5Y cells induced by MPP+was measured with MTT assay, the morphology of SH-SY5Y cells was observed. The expression of microtubule associated protein 1 light chain 3 (LC3)-II/I and Beclin 1 protein was detected by Western blotting. And the expression of LC3-II/I and Beclin 1 mRNA were assayed by re-al-time quantitative reverse transcription-PCR (RT-PCR). Results The viability rates of cells were significantly lower in group B than in group A (t=20.270, P<0.001), and were significantly higher in groups C and D than in group B (t>8.770, P<0.001), however, there was no significantly difference between groups C and D (t=2.270, P=0.064). The expression of LC3-II/I and Beclin 1 was higher in group B than in group A (t>6.647, P<0.01), and was higher in groups C and D than in group B (t>3.630, P<0.01), however, there was no significantly differ-ence between groups C and D (t<2.238, P≥0.05). Conclusion Butylphthalide could prevent the injury of SH-SY5Y cells induced by MPP+, which may affect Parkinson's disease by inducing autophagy.
