ABSTRACT
Objective:To explore the effect of combining motor imagery therapy (MIT) with kinesio taping in rehabilitating the upper limb motor function of stroke survivors.Methods:Ninety-two stroke survivors were randomized into a control group ( n=31), an MIT group ( n=31), and a combination group ( n=30). All were given 40 minutes of basic rehabilitation therapy daily, while the MIT group received additional MIT therapy, and the combination group received kinesio taping with the MIT therapy. The taping was applied according to a patient′s condition and changed every other day. The MIT was conducted twice a day. The experiment lasted 8 weeks, six days a week. Before and after the 8 weeks, the upper limb functioning, ability in the activities of daily living and muscle tension of each subject were assessed using the Fugl-Meyer assessment for the upper extremities (FMA-UE), the Hong Kong version of the functional test for a hemiplegic upper extremity (FTHUE-HK), the modified Barthel index (MBI) and the modified Ashworth scale (MAS). Results:The average post-treatment FMA-UE and MBI scores of the combination group were significantly higher than those of the MIT group, and both were significantly higher than the control group′s averages. The average FTHUE-HK grading of the combination group and MIT group after the treatment was significantly higher than in the control group, with that of the combination group significantly superior to the MIT group′s average. After the intervention the average MAS rating of the combination group was significantly lower than that of the control group.Conclusion:MIT combined with Kinesio taping can significantly improve the upper limb motor functioning of stroke survivors, and significantly reduce their abnormal muscle tone compared to traditional treatments.
ABSTRACT
Objective:To analyze the molecular characteristics of Echovirus 11 (Echo11) strains isolated in Xiangyang, Hubei Province from 2016 to 2017 based on the sequences of VP1 gene.Methods:Rectal and throat swab specimens were collected from children with hand, foot and mouth disease (HFMD) in Xiangyang from 2016 to 2017. Echo11 strains were detected by real-time reverse transcriptase PCR (RT-PCR) and isolated after cultured in human rhabdosarcoma (RD) cells. The VP1 regions of Echo11 strains isolated from RD cells and the whole genomes of three representative Echo11 strains were amplified by conventional RT-PCR and the sequences were analyzed. DNAStar7.0 (MegAlign) and MEGA6.0 (Data) were used to analyze the homology and mutation sites in nucleotide and amino acid sequences. Neighbor-joining method was used to construct phylogenetic trees. Recombination analysis was performed with SimPlot software (BootScanning).Results:A total of 11 Echo11 strains were isolated from 3 494 HFMD cases, accounting for 0.31%. They were highly homologous in the VP1 gene. These strains shared 98.4%-100.0% homology in nucleotide sequences and 98.3%-100.0% homology in amino acid sequences. The homology between the 11 Echo11 strains and the prototype strain (Echo11/Gregory, X80059) was 73.9%-74.8% in nucleotide sequences and 87.7%-88.7% in amino acid sequences. All of the Echo11 strains circulating in Xiangyang were classified into lineage D, having a similarity to the strains circulating in some regions of mainland China since 2013. In multiple regions of the genome, the Echo11 strains isolated in Xiangyang were highly similar to the Henan Echo1 strains in 2010 and the Hubei Echo6 strains in 2015, suggesting there was recombination within the genome of Echo11 strains in Xiangyang.Conclusions:The Echo11 strains circulating in Xiangyang from 2016 to 2017 belonged to lineage D and were recombinant strains.
ABSTRACT
Objective To investigate the effect of transcranial direct current stimulation (tDCS) combined with motor imagery therapy on the function of upper limbs of stroke survivors.Methods Ninety-four stroke patients were randomized into a routine group (n=31),a motor imagery group (n=31),and a combination group (n =32).All the patients received basic routine rehabilitation therapy,while the routine group accepted traditional occupational therapy,the motor imagery group accepted motor imagery therapy,and the combination group accepted tDCS and motor imagery therapy.The upper limb function of the patients was assessed using Fugl-Meyer assessment (FMA) of upper extremities,the Hong Kong version of functional test for the hemiplegic upper extremity (FTHUE) and the modified Barthel Index (MBI) before and after 8-week treatment.Results The average FMA of the combination group and motor imagery group were (37.81 ± 12.80) and (31.39± 15.62),respectively,both significantly higher than that of the routine group (27.61± 14.90).The average FTHUE of the combination group and motor imagery group was both significantly higher than that of the routine group.Moreover,the average MBI of the combination group and motor imagery group were (57.78±7.73) and (51.87±9.31),respectively,both significantly higher than that of the routine group (45.19:t:9.07) (P＜0.05 for all).Conclusion tDCS combined with motor imagery therapy can significantly improve the upper limb function of stroke patients,significantly superior to tDCS or motor imagery therapy solely.
ABSTRACT
Objective To study the effect of methylphenidate on urinary endogenous metabolites in children with ADHD, and to explore the mechanism of methylphenidate. Methods The metabolites of urine in 37 children with ADHD treated with methylphenidate before intervention (case 0 week group), intervention for 6 weeks (6 weeks group), intervention 12 weeks (12 weeks group, and 40 healthy subjects (control group) were measured by gas chromatography-mass spectrometry (GC-MS), and analyzed by orthogonal partial least squares (OPLS) to find the significant differences biomarkers. Results The urine metabolic profile of the control group, the 0 week group and the 12 week group showed obvious changes. The metabolic profile of the 0 week group and the control group was differentiated, and the 12 week group was away from the 0 week group, and closed to the control group. 24 significant differences metabolites were identified using commercially available metabolite libraries (such as the Wiley and NIST mass pools) and the standard metabolite library established in our laboratory. The levels of these metabolites were reversed to normal level due to methylphenidate intervention. Conclusion This study shows that methylphenidate has a good curative effect on children with ADHD. Its mechanism is related to the metabolic abnormalities of pyruvate metabolism, tryptophan metabolism, phenylalanine metabolism, glycine, serine and threonine metabolism. The possible mechanism of methylphenidate in the treatment of children with ADHD was revealed from the overall metabolic point of the body. Metabolomics reveals possible therapeutic mechanism of methylphenidate for children with ADHD from overall metabolism of the body.

ABSTRACT
Dengue virus ( DENV) threatens the lives of hundreds of millions of people every year. Animal model is an effective tool for virus pathogenesis research and vaccine evaluation. At present, the de-velopment of animal models of DENV infection and disease has been challenging, as epidemic DENV does not naturally infect non-human species. Animal models of dengue virus infection are mainly non-human pri-mate ( NHP) model and mouse model. NHPs have been used to study dengue infection and candidate vac-cines because they can sustain viral replication in relevant cell types and develop a robust immune response, but they do not develop overt disease. However, NHP models are not suitable for early preclinical studies be-cause the cost of using these animals is high. In contrast, mouse models that are established mainly by using wild-type and immunodeficient mice can be more economical for preclinical evaluation of dengue vaccines. Overall, every model has its advantages and disadvantages and is differentially suited for studies of dengue pathogenesis and immunopathogenesis and/or preclinical testing of antiviral drugs.

ABSTRACT
Objective To analyze the risk factors in the operative mortality in neonates with congenital heart disease.Methods The surgical outcomes of eongenital heart defects in 231 neonates at Shanghai Children's Medical Center Affiliated to Shanghai Jiaotong University of Medicine,during Jan.2011 and Dec.2013 were detected for retrospectively.Patients were analyzed according to Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1).The age,weight at operation,emergency operation,cardiopulmonary bypass,single ventricle surgery,and RACHS-1 score were detected for risk assessments.Results Overall mortality of congenital heart defect in neonates was 9.96％ (23/231 cases).The top three procedures for high mortality were single ventricle palliative surgery.(25.00％,7/28 cases),corrective operation of interrupted aortic arch (21.43％,3/14 cases),and arterial switch operation with ventricular septum defect repair (13.95％,6/43 cases).There was only 1 case of pulmonary atresia with intact ventricular septum repair,and the case was not classified into high mortality category.With the elevation of RACHS-1,the mortality increased.The mortality rate was 6.67％ (2/30 cases) in RACHS-1 as category 2,6.84％ (8/117 cases) in 3,13.75％ (11/80 cases) in 4,and 50.00％ (2/14 cases) in 6.Multivariable analvsis of risk factors for death showed that single ventricle palliative operation,body weight less than 3 000 g,and RACHS-1 were independent risk factors for mortality.Conclusions This study shows the surgical mortality in neonates with congenital heart defect is still high.Further prospective analysis of specific treatment strategies for high risk patients above was needed and the strategy for single ventricle operation in neonates should be optimized.
ABSTRACT
Objective The bidirectional cavopulmonary shunt (BCPS) is a major step in the staged palliation of functionally univentricular heart defects.Whether to preserve of additional pulmonary blood flow (APBF) has been a highly controversial issue.The purpose is to mathematical model and set out to determine the significa advantages and disadvantages of bidirectional cavopulmonary shunt with additional pulmonary blood flow:a theoretical analysis nce of APBF and the appropriate APBF ratio.Methods We used models of the univentricular circulation after the bidirectional cavopulmonary anastomosis with additional pulmonary blood and to computational analyze the impact of APBF on oxygen delivery,APBF flow on the CVP and SaO2.Results The influence of APBF depends on the ratio of superior vena cava flow to inferior vena cava flow ( QSVC/QIVC ).For QSVC/QIVC ＞ 0.3,APBF may be associated with decreased oxygen delivery.For QSVC/QIVC ＜ 0.3,appropriate APBF may be associated with increased oxygen delivery.A linear relationship exists between the increase of APBF and CVP,and the slope was depended on the value of pulmonary vascular resistance.Estimating APBF from CVP measurements may be a feasible method.A nonlinear relationship between the increase of APBF and oxygen saturation,and estimating APBF from SaO2 measurements may result in errors.BCPS and appropriate APBF may optimal the oxygen delivery with the increase of age and the decrease in QSVC/QIVC.For patients who accepted BCPS without APBF,there is a decreasing tendency of oxygen delivery with the increase of age and the decrease in QSVC/QIVC.For patients who suffered pulmonary arterivenous malformation,there is a more obvious decrease in oxygen delivery.ConclusionFor patients under age who has normal pulmonary vascularbed ( that is,QSVC/QVC ＞ 0.3),elimination of additional pulmonary blood flow can improve the oxygen delivery under a given cardiac output.For patients who with hypoplastic pulmonary vascular or in older patients under age,APBF is necessary to improve oxygen delivery.For patients who have to accept BCPS as the final procedure,preserving of APBF is suggested.
