Objective:To investigate the effect of upper limb pillow position on hemodynamic and safety of patients undergoing cerebellopontine angle tumor resection.Methods:Eighty-four patients receiving cerebellopontine angle tumor resection in our hospital from January 2016 to December 2019 were randomly divided into the experimental group (42 cases) and the control group (42 cases). Patients in the control group were placed in routine upper limb position, while patients in the experimental group were placed in upper limb pillow position. The data including systolic pressure, diastolic pressure, heart rate, saturation of blood oxygen were recorded on admission of operation room, completing placing body position, 30 minutes and 60 minutes after operation and after finishing the operation. The numbness/soreness of upper limbs and pressure injury rate was compared between the experimental group and the control group.Results:The rate of numbness/soreness of upper limbs were 2.4% (1/42) in the experimental group, 19.1%(8/42) in the control group, the differences were statistically significant ( χ2 value was 6.098, P<0.05). The stage 1 pressure injury were 2 cases in the experimental group, stage 1 and 2 pressure injury were 6 cases and 2 cases, respectively in the control group, the differences were statically significant ( Z value was 2.039, P<0.05). Conclusion:Upper limb pillow position of the operation side can reduce postoperative complication of patients undergoing cerebellopontine angle tumor resection, but will not increase the risk of abnormal hemodynamic fluctuation.

OBJECTIVE: To determine the prevalence of GJB2 mutations in newborns and provide clinical experience for newborn genetic screening. METHOD: Blood samples of 23 836 newborns in Beijing from March 2012 to December 2013 were screened for hot spot mutations of GJB2 associated with hearing loss. The genetic screening results were comprehensively analyzed with hearing results in genetic counseling. RESULT: One or two pathogenic mutations of GJB2 were spotted in 622(2. 61%) individuals. Among them, numbers of newborns with 1 mutation of c. 35deiG,c. 176191 del16,c. 235delC and c. 299300 delAT were 3,26,467 and 120. One compound heterozygote, and 5 homozygotes were also identified. Five hundred and fifty(88. 6%)newborns were followed up by telephones and SMS (short message service) and 325 newborns visit our genetic clinic regularly which were regarded as the research object. In the hearing screening, the referral rate for hearing loss in the first-step screening was 13.8% (45/325), and became 9.2% (30/325) upon retesting. Nine newborns (2. 8%) were diagnosed as hearing loss of different degrees as early as 3 months old,including 6 homozygous/compound heterozygote and 3 heterozygotes. CONCLUSION Patients with GJB2 mutations have various phenotype. Newborns with homozygous/compound heterozygous GJB2 mutations may pass the hearing screening at first. Carriers of GJB2 may also have hearing problems. The combination of genetic and audiological screening can play an important role in deafness detections of infants before key period of speech development.

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.
