ABSTRACT
Developmental coordination disorder (DCD) is a childhood-onset condition that primarily affects physical co-ordination.In China, DCD is not well recognized and is under-treated.Knowledge of the evaluation and intervention of DCD among physiotherapists (PT) is limited.In 2020, the Academy of Pediatric Physical Therapy of the American Physical Therapy Association published the Physical Therapy Management of Children with Developmental Coordination Disorder: An Evidence-Based Clinical Practice Guideline.From the perspective of PT, this review aims to make a comprehensive interpretation of the recommendations in the guideline regarding the physical examination and evaluation, physiotherapy planning and implementation, and family education of children at risk or diagnosed with DCD.This article aims to make DCD get more attention from domestic PT through the interpretation of the latest guidelines, and strengthen the knowledge of physiotherapy assessment and management in children with DCD to guide the clinical practice.
ABSTRACT
Occupational therapy can not only promote the development of motor and cognitive functions in children with developmental or other disabilities, but also improve their self-care ability, learning ability, participation skills and other activities.In 2019, the Aust Occup Ther J published a systematic review on the effects of occupational therapy interventions on disabled children, aiming to summarize the best evidence of occupational therapy and help occupational therapists and families to choose the effective treatment regimens.In this article, the systematic review was interpreted in light of the current status of domestic child occupational therapy, so as to allow clinicians to compare the pros and cons of different treatment methods and improve the efficacy.

ABSTRACT
Objective To detect the expression of dead box 1(DDX1)gene in tumor tissue and pericarcino-matous tissue of clinical neuroblastoma(NB)samples,and explore the relationship between DDX1 and NB. Methods Five cases of pathological specimens in children with NB were chosen from Department of Pathology,the First Affi-liated Hospital of Xinxiang Medical University between January 2012 and December 2014. In the 5 cases,3 cases were male,2 cases were female,the age of 1 - 5 years old,average age(2. 1 ± 1. 6)years. The NB tissue and pericarcino-matous tissue(pericarcinomatous tissue was normal tissue which was at least 2 cm from the tumor tissue)of 5 children were collected and fixed in 40 g/ L formaldehyde solution. Then with the conventional dehydration,embedding,sectio-ning, dewaxing, hydration, antigen repair, add primary antibodies, secondary antibodies, diaminobenzine chromogenic. The expressions of DDX1 in tumor tissue and pericarcinomatous were observed with light microscopy and with semi - quantitative analysis.(1)Staining degree:no staining with 0 score;light staining with 1 score;medium staining with 2 scores;deeply staining with 3 scores.(2)Positive cells proportion:positive cells proportion ﹤ 10% with 0 score;positive cells proportion within 10% - 30% with 1 score;positive cells proportion within 31% - 60% with 2 scores;positive cells proportion ﹥ 61% with 3 scores. Final scores were a half of the sum of staining degree score and positive cells proportion score,final score within 0 -1. 0 with - ,1. 1 -2. 0 with + ,2. 1 - 3. 0 with + + ,3. 1 -5. 0 with + + + . Results DDX1 were expressed in NB and pericarcinomatous tissues,but visible DDX1 positive staining number more and deeper in NB,DDX1 positive staining number less and light in pericarcinomatous tissues. Five cases of pericarcinomatous tissues immunohistochemical semi - quantitative score were negative and final scores were 1. 0 score or less,the mean value was 0. 5 score. NB immunohistochemical semi - quantitative score were+or + +and final scores were 1. 5 score or higher,the mean value was 1. 8 scores,the expressions of DDX1 were sig-nificantly higher in NB than the pericarcinomatous tissues. Conclusions DDX1 is highly expressed in NB,which may contribute to the development of NB. This suggest DDX1 may serve as an oncogene and play a catalytic role in the de-velopment of NB,which provides a clinical evidence for the follow - up study.
ABSTRACT
Objective To explore the effects of dead box 1 (DDX1) gene on invasion,migration and drug resistance capability of neuroblastoma(NB) cells.Methods According to the virus drop degree,the appropriate amount of target virus(Lenti-DDX1-MIR virus liquid,drop degrees 1012 TU/L) and negative control virus(Lenti-EGFP virus liquid,drop degrees 3 × 1011 TU/L) (multiplicity of infection was 10) were added into 2 hole cells,respectively.SK-N-BE(2)/blank,SK-N-BE(2)/shV and SK-N-BE(2)/shDDX1 cells which grew in good condition were cultured.Transwell chamber was used to detect the invasion,and cell staining was made with crystal violet.The researchers calculate 5 field counting in each small room and calculate the average cell invasion rate.Transwell chamber was used to detect the migration,and cell staining was made with crystal violet.The 570 nm absorbance values was tested with enzyme linked immunosorbent assay (ELISA) reader,and cell migration was calculated.The researchers used 50 mg Cisplatin,solution 10 g/L mother liquor standby with 5 mL dimethyl sulphoxide,and 50 mg Doxorubicin,solution 1 g/L mother liquor standby with PBS.Drugs were added to the cell culture plate,and Doxorubicin final concentration was 1.0 mg/L,and Cisplatin final concentration was 2.5 mg/L,and photographic record was documented after drug treatment for 24 h.Cell Count Kit-8 (CCK-8) was used to detect the drug sensitivity to NB cells to Doxorubicin and Cisplatin.Results Transwell results showed that,cell invasion concentration in SK-N-BE (2)/shDDX1 was 60％ compared with SK-N-BE (2)/blank and SK-N-BE (2) /shV;Crystal violet staining showed that cell invasion of SK-N-BE(2)/shDDX1 was significantly weaker than that of SK-N-BE(2)/blank and SK-N-BE(2)/shV cells,that is to say,DDX1 knockdown reduced the cell invasion of NB.Transwell results showed that,cell migration concentration in SK-N-BE(2)/shDDX1 was 50％ compared with SK-N-BE(2)/blank and SK-N-BE(2)/shY;Crystal violet staining showed that cell migration of SK-N-BE(2)/shDDX1 was significantly weaker than that of SK-N-BE(2)/blank and SK-N-BE(2)/shV cells,that is to say,DDX1 knockdown reduced the cell migration of NB.With DDX1 knockdown,24-h inhibition rate of SK-N-BE (2)/shDDX1 cell was 1.93 times of SK-N-BE (2)/shV cell with 1.0 mg/L Doxorubicin,24 h inhibition rate of SK-N-BE(2)/shDDX1 cell was 1.38 times of SK-N-BE(2)/shV cell with 2.5 mg/L Cisplatin.DDX1 knockdown could increase the Doxorubicin and Cisplatin drug sensitivity to NB cells.Conclusion DDX1 knockdown can decrease the cell invasion,migration and resistance capability of NB and increase the Doxorubicin and Cisplatin drug sensitivity of NB cells.
ABSTRACT
Objective To explore the effects of dead box 1 (DDX1) gene on cell apoptosis,proliferation and cell cycle of neuroblastoma(NB) cells.Methods SK-N-BE(2)/blank,SK-N-BE(2)/shV and SK-N-BE (2)/shDDX1 cells were seeded in 96-well plates,which grew in good condition and in the logarithmic growth phase,5 000 cells were inoculated in each well and 5 repeated holes were set.Cell count kit 8 (CCK-8) was used to detect the cell number at 12 h,24 h,36 h,48 h,and the average was calculated.The time (hour) was set as abscissa,the optimal density (A) value at 450 nm was set as vertical axis,and the growth curves of these 3 cells were drawn to investigate the effects of DDX1 on the proliferation of NB cells.After 24 h,flow cytometry (PI staining) was used to detect the apoptosis of SK-N-BE (2)/blank,SK-N-BE (2)/shV and SK-N-BE (2)/shDDX1 cell lines to observe the effects of DDX1 on the apoptosis of NB cells.After 24 h,flow cytometry (PI staining) was used to detect the proportion of SK-N-BE(2)/blank,SK-N-BE(2)/shV and SK-N-BE(2)/shDDX1 cells at G1,S,M,G2 stage to observe the effects of DDX1 on the cell cycle of NB cells.Results SK-N-BE (2)/shDDX1 cell proliferation was significantly lower than SK-N-BE(2)/blank and SK-N-BE(2)/shV cells,that was to say,DDX1 knockdown reduced the cell proliferation of NB.According to the flow cytometry results,the total average apoptosis rate was 5.28％ in SK-N-BE (2)/shV cells,and the total average apoptosis rate was 9.99 ％ in SK-N-BE (2)/shDDX1 cells.The number of apoptotic SK-N-BE (2)/shDDX1 cells was significantly higher than the number of SK-N-BE (2)/blank and SK-N-BE (2)/shV cells,which indicated that DDX1 knockdown increased tumor cell apoptosis of NB.Compared with SK-N-BE(2)/blank and SK-N-BE(2)/shV cells,the cell cycle of SK-N-BE(2)/shDDX1 cells was arrested,and the proliferation was affected.Conclusions After DDX1 expression is inhibited,the cell cycle of NB cells are affected,the cell apoptosis is increased,and the cell proliferation is reduced.

Objective To conduct the epidemiological investigation and analysis of cerebral palsy in Xinxiang of Henan Province and to investigate its risk factors in order to provid a basis for further study of etiology and prevention of cerebral palsy information.Methods Cluster sampling survey was carried out among children aged 1-6 years in XinXiang,Henan Province,and the data were analyzed by using SPSS 13.0 statistical analysis software.Results The morbidity of infantile cerebral palsy in Xinxiang of Henan Province was 2.82‰.The prevalence distribution in all age groups was 2.46 ‰-3.11‰(x2 =0.374,P =0.996),and the prevalence rate in male and female was significantly different(x2 =0.139,P =0.709) ; the sex ratio was 1.09 ∶ 1.00.Prevalence rate was slightly lower in urban areas than in rural areas (x2 =0.526,P =0.769).But no significant differences were observed in all of the data above.The incidence of cerebral palsy of children whose mothers did not established perinatal care manual and guidance during pregnancy was 5.86 times of the children whose mothers established perinatal care manual and guidance (x2 =116.806,P =0.000) ;the incidence of cerebral palsy in children whose mothers did not receive regular prenatal care during pregnancy was 5.37 times of the children whose mothers receive regular prenatal care during pregnancy (x2 =43.904,P =0.000);the incidence of cerebral palsy in children who had no neonatal follow-up after birth was 8.55times of the children with neonatal follow-up after birth (x2 =68.987,P =0.000).The incidence of cerebral palsy in children whose developmental disorders were not timely diagnosed and treated medically was 5.39 times the children whose developmental disorders were timely diagnosed and treated (x2 =56.003,P =0.000).The significant differences were observed in all of the data above.In the classification of cerebral palsy,the spastic type was the most (42.1％) ;followed by the dyskinetic (24.6％) ; the mixed (18.8％) ; and the ataxia(14.5％).Conclusions The survey results can reflect current prevalence of infantile cerebral palsy in children aged 1-6 years in XinXiang,and can be served as a basis for further prevention and treatment of cerebral palsy information.
ABSTRACT
Objective:Discuss and analyze the mechanisms of spine fine adjusting through the observation of the therapeutic effect in treating cervical spondylotic radiculopathy(CSR)and the conversion of cervical curvature.Methods: Randomly divide 106 CSR patients into two groups–manipulation therapy group and traction therapy group,53 for each.Judge the therapeutic effect by evaluation scales and measure the cervical curvature on X-ray photographs.Results:The symptoms and physical signs of the patients in both two groups have been improved(P
