Objective To compare the effect of motor development massage and neural development approach on the children with cerebral palsy. Methods The children with cerebral palsy were selected with layered matching as they accepted motor development massage or neural development approach, and reviewed with their score of Gross Motor Function Measure (GMFM-66). Results There were 24 children in each group. The GMFM-66 score increased after treatment in both groups, but there was no statistical difference between these groups. Conclusion The gross motor function can be improved in the children with cerebral palsy with motor-development massage and neural development approach similarly.

Objective To analyze the correlation between gross motor function and activities of daily living(ADL)in children with cerebral palsy.Methods 42 children with CP(26 males,16 females,average age 49.5±21.5 months,11 children with spastic quadriplegia,22 with spastic diplegia,5 with spastic hemiplegia,2 with athetosis and 2 with dystonia)were assessed with Gross Motor Function Classification System(GMFCS)and Gross Motor Function Measure(GMFM)for the assessment and classification of gross motor function.Pediatric Evaluation of Disability Inventory(PEDI)was used to assess the ADL.The ADL of children with different levels of GMFCS and the correlation between gross motor function and ADL were analyzed.Results The more severe of GMFCS,the less standard score of PEDI.There was the highest correlation between the GMFM66 scores and scaled scores of PEDI in mobility and social function(r=0.84),whereas a weaker correlation appeared between GMFM66 scores and scaled scores of PEDI in social function(r=0.72).Conclusion Since the gross motor function of children with CP greatly affects the ADL,the gross motor function training should be the main item for CP children,the training goal of ADL should be made according to the levels of GMFCS.

Objective To analyze the activities of daily living (ADL) performance in children with cerebral palsy (CP) with different gross motor function and the correlation between gross motor function and ADL perform-ance. Methods A total of 118 children (81 boys and 37 girls; mean age: 47.7 months, SD: 20.1 months, age range: 18-90 months) with CP were recruited from three different rehabilitation centers in Shanghai. Types of CP included hemiplegia (n = 27), spastic diplegia (n = 53), spastic quadriplegia(n = 29), athetoid (n = 4), dystonic (n = 4), ataxic (n = 1). Gross motor function classification system (GMFCS) and Gross motor function measure (GMFM) were adopted to assess and classify the gross motor function. Pediatric evaluation of disability inventory (PEDI) was adopted to assess ADL performance. Differences of PEDI scores were compared among different levels of GMFCS; and the correlation between GMFCS levels, GMFM scores and PEDI scores were analyzed. Resnlts PEDI scores showed significant differences among CP children with different levels of GMFCS. The PEDI score usually de-creased with the increase of the GMFCS level, and mobility ability was the lowest. Significant correlations were found between PEDI scaled scores and GMFCS (rs = 0.85～0. 50, P < 0.001). Various levels of correlations (r = 0. 85～ 0.54, P<0.001) were found between GMFM scores and PEDI scaled scores. Higher correlations were found between GMFCS levels, GMFM scores and mobility ability. Conclusion ADL performance was significantly different among CP children with different gross motor function. The higher the gross motor function, the better the performance of ADL. Mobility would be improved by promoting gross motor function in CP children. The training of self-care and so-cial communication ability should be emphasized.

Objective To investigate the clinical value of 3.0T MRI for hilarcholangioc-arcinoma diagnosis.Methods T Totally48 hilarcholangiocarcinoma patients from October 2011 to June 2015 underwent diagnoses by 3.0T MRI and 64-slice spiral CT,and then the diagnosing results were compared with those by surgery and pathological examination to determine the value of 3.0T MRI for hilarcholangiocarcinoma diagnosis.Results 3.0T MRI had the positioning accuracy (100％) and qualitative accuracy (95.83％) significantly higher than the positioning accuracy (79.17％) and qualitative accuracy (81.25％) (P＜0.05).In case of hepatic duct dilatation,CT found 35 cases of hilar masses,14 cases of lymphoma,5 cases of hepatic duct wall invasion and 9 cases of portal vein invasion,while 3.0T MRI displayed 44 cases of hilar masses,26 cases of lymphoma,13 cases of hepatic duct wall invasion and 30 cases of portal vein invasion.Conclusion 3.0T MRI has high positioning and qualitative accuracies when used to diagnosing hilarcholangiocarcinoma,behaves well in displaying hepatic duct dilatation,high resolution of soft tissues,and thus is worthy promoting clinically.

Objective To investigate the esthetic effect of anterior ultra-thin veneers which were fabricated from heat pressed IPS e.max press ingots of high translucency.Methods The whole 62 anterior teeth of 12 patients,who wanted to receive aesthetic restorative treatment,were invloved in the study.Grooves with 0.5 mm depth were marked at the center of the labial face by the use of spherical diamond burs with 1 mm in diameter.At the cervix of the teeth,the design of 0.3 mm shallow concave shoulder was adopted.IPS e.max HT ingots of different color were chosen to be hotpressed; the straining technique was used on the marginal ridge and incisor ridge of the ultra thin veneers after they had been carefully trimmed.Subsequently,the restorations were bonded with Variolink Veneer resin cement.After a short-term follow-up for 3 years,a modified USPHS criterion was used to evaluate the esthetic effect.Results The thickness of the ultra-thin veneers fabricated by heat pressing was 0.3-0.5 mm,marginal integrity of the veneers was perfect and fitted well with the marginal finishing line of the abutment,and then the translucency of veneers was high.There was no edge discoloring after the veneers were used for 6 months to 3 years,and they might produce an excellent chameleon effect by mixing the color of adjacent teeth and gums,and appeared a surface morphology of natural enamel after carefully carved.In the short-term clinical observation,none of the 62 veneers fractured or fell off; there was no case of dentin hypersensitivity.Conclusions Ultra-thin veneers fabricated from IPS e.max Press ingots have the following advantages,a simple operating procedure,high mechanical strength,and satisfactory esthetic effect.

BACKGROUND: With the comprehensive promotion of spinal internal fixation technology, the remodeling of spinal mechanical stability has attracted more and more attention. Lateral internal fixation via axillary midline transthoracic approach for the treatment of upper thoracic vertebra lesion is a new surgical approach. Currently, the research on the biomechanics of upper thoracic vertebra after fixation is relatively rare. OBJECTIVE: To evaluate whether the reconstruction of upper thoracic vertebrae via axillary midline transthoracic approach can achieve the requirements of biomechanical stability by biomechanical analysis of three-dimensional motion stability and load-bearing strength of upper thoracic vertebrae in lateral and anterior internal fixation models. METHODS: The C7-T6 spine and bilateral rib cage joint specimens were obtained from 12 human cadaveric bodies, and the three-dimensional motion stability test of the complete upper thoracic vertebrae model was performed and recorded as a complete vertebral body group. Subsequently, the specimens were randomly divided into two groups, and the traditional front plate internal fixation (front internal fixation group) and the axillary line into the thoracic cavity side plate internal fixation models (lateral internal fixation group) were established, respectively, with six specimens in each group. Three-dimensional motion test, vertical pressure test and vertical pressure failure test were performed. This study was approved by the Ethics Committee of Second Affiliated Hospital of Guangxi Medical University (approval No. 2017(KY-0080)). RESULTS AND CONCLUSION: (1) The load of left vertebral body group under left/right flexion, flexion/posterior extension and left/right rotational motion was smaller than that of lateral internal fixation group and anterior internal fixation group (P < 0.01). The load in the front internal fixation group under left/right rotational motion was smaller than that in the lateral internal fixation group (P < 0.05). There was no significant difference between the left/right flexion and the flexion/rear extension between the anterior internal fixation group and the lateral internal fixation group (P > 0.05). (2) When the load reached 600 N, the vertebral body sinking displacement of the front internal fixation group was smaller than in the lateral internal fixation group [(1.39±0.20), (2.15±0.17) mm, P< 0.01]. (3) There was no significant difference in the maximum intensity load between the anterior internal fixation group and the lateral internal fixation group [(1 839.70±122.45), (1 798.65±120.21) N, P=0.571], (4) Results showed that the axillary midline transthoracic approach was in the lateral steel plate. The fixation is stable and meets the biomechanical needs of spinal reconstruction.

Objective To find deficiencies in the existing students' teaching evaluation by in-vestigation and to improve the work in teaching evaluation. Methods Totally 787 students and 261 teachers were investigated by the questionnaire. Contents of questionnaire include interference factors of students' teaching evaluation, experts and teachers' initiatives, students' opinions on how to play the role of evaluation, feedback from experts, etc. Results were analyzed by SPSS 17.0 t test and sta-tistical description. Results Teacher exerted less impact on students' initiative of teaching evaluation and 221(84.7%) teachers said that they would never relax requirements for students because of the evaluation. 37.0%(291/787) students said that experts took the initiative to understand the teaching condition and 65.9%(519/787) students said that teachers took the initiative to understand the study condition. Students thought that teaching evaluation can help improve teachers' teaching ability but lack of powerful guidance after evaluation, insufficient recognition on evaluation opinions and delayed feedback affected the progress of the evaluation work. Conclusions Teaching assessment is very im-portant. Therefore, we should improve the enthusiasm of students in the assessment and make use of student's academic performance rationally in order to make the teaching evaluation play a greater role in improving teaching quality.

Objective To study the application value of electroencephalogram and CT in children with cerebral palsy.Methods Electroencephalogram and CT examinations were carried out in 224 children with cerebral palsy.Results Abnormal prevalence of electroencephalogram was 47.77%, 58.88% of which were found as epileptic discharge. Abnormal prevalence of CT was 79.46%. The abnormal rate of CT was significantly higher than that of electroencephalogram ( P<0.001). The abnormal rates of electroencephalogram and CT among different types of cerebral palsy were not significantly different ( P>0.05).Conclusion Combination of CT and electroencephalogram will be helpful for the diagnosis and treatment in children with cerebral palsy.

Objective: To study the therapeutic effects of combined treatment with Chinese and western medicine in children with cerebral palsy (CP). Methods: 104 CP children were treated mainly with physiotherapy and acupuncture, together with occupational therapy, sensory integration and electrical stimulation. Gross Motor Function Measure (GMFM) was used to assess the effects of treatment. Results: After treatment for 3.29±0.80 months, the majority of CP children improved their IQ and limb symptoms, with decreased abnormal posture, increased muscle strength and improved motor developmental function. GMFM88 and GMFM66 scores had significantly increased after treatment. Conclusions: Combined treatment with Chinese and Western Medicine has confirmed effects on CP children.

Objective To analyze the clinical features of differentiated thyroid cancer diagnosed during pregnancy or one year after delivery.MethodsA total of 234 women with differentiated thyroid cancer were treated from January 2001 to January 2011.Cases were divided into three groups according to the time of tumor diagnosis( group 1,no pregnancy history; group 2,during pregnancy or in the first year after delivery;group 3,longer than 1 year after the delivery).ResultsThe thyroid nodule was asymptomatic and discovered on routine examination more often in group 2(78.7％ ) than other two groups (P =0.02).There were no significant difference among three groups in age,hospitalization time,operation time,operation method,tumor type,primary tumor stage and mortality. But more patients in group 2 were suffering from extrathyroid invasion ( P =0.024 ),multi-focal cancer ( P =0.023 ),larger cervical lymph node ( P =0.021 ),later regional lymph node stage (P =0.020 ) and higher local recurrence (P =0.001 ).By stepwise logistic regression analysis,pregnancy is one of the factors impacting on local recurrence rate ( P =0.045 ).ConclusionsPregnancy does not affect the mortality of the differentiated thyroid cancer,but the incidence of extrathyroid invasion,multi-focal cancer,cervical lymph node metastasis,local recurrence is higher in patients with differentiated thyroid cancer diagnosed during pregnancy.
