Objective To explore the influence factors both at birth and after birth to the brain development of small for gestational age(SGA) infants. Methods The cerebellar area, cerebellar circumference, vertical lengths of the vermis and maximum transverse width of the cerebellar body both in midline sagital view and coronal view as well as the width of cerebral hemisphere in coronal view were measured in SGA infants through anterior fontanels by inter cranial ultrasound, and the parameters were compared with that in AGA infants. Results The cerebellar area, cerebellar circumference, vertical length of the vermis and maximum transverse width of the cerebellar body both in midline sagittal view and coronal view correlated significantly with the gestational age and birth weight and the cerebellar area and circumference correlated best with the gestational age and birth weight of infants. The width of cerebral hemisphere were also correlated significantly with birth weight. The brain growth of SGA infant was retarded at birth. The rate of the brain growth and development of SGA was accelerated after birth. It was smilar to that of AGA group, but at the age of 12 months the brain development in SGA infants was still retarded. Conclusion The growth of brain both before and after birth were retarded. Better perinatal health care and early intervention after birth should be developed.

ObjectiveTo investigate the effects of swallowing training combined with real-time electrical stimulation on dysphagia after stroke. Methods17 patients, older than 80 years old, with dysphagia after stroke, were treated with Vocastim-Master Physiomed Elektromedizin. They were assessed with the Watian drinking water test, swallowing disorder evaluation, swallowing ability evaluation, and α. ResultsAll the assessment significantly improved in the 17 patients (P<0.001). ConclusionSwallowing training combined with real-time electrical stimulation can significantly improve the swallowing capacity of the patients older than 80 after stroke.

ObjectiveTo determine the responsiveness of 3 assessment for swallowing disorder on elderly people. Methods40 elderly cases with were assessed with drinking test, classification of swallowing disorder, and swallowing ability evaluation before and 3 weeks after treatment. ResultsThe effect size was 1.04 for drinking test, 1.74 for classification of swallowing disorder and 2.06 for swallowing ability evaluation. The standardized response mean was 2.49 for drinking test, 2.35 for classification of swallowing disorder and 2.78 for swallowing ability evaluation. There was very significant difference before and after treatment in the score of all the scales (P<0.001). ConclusionDrinking test, classification of swallowing disorder, and swallowing ability evaluation are responsive for swallowing disorder in elderly people receiving rehabilitation.

Objective The stress reaction in double-balloon enteroscopy was investigated,the influencing factors and intervention countermeasures were studied.Methods Cardiovascular effects and physiological reactions of 60 double-balloon enteroscopy patients were surveyed.The patients were divided into 2 groups according to the cardiovascular effects to underwent single factor analysis of related factors.Results The incidence of physiological reactions was 68.3%,the incidence of cardiovascular reactions was 56.7%.Evident difference existed in blood pressure,heart rate and blood oxygen saturation rate before,during and after examination.The grouping analysis showed cardiovascular effects were influenced by many kinds of factors.Conclusions Different degrees of the stress reactions in double-balloon enteroscopy might appear.The influencing factors included the enteroscopy mode and time,gender,age,mood,and physician operation experience.The stress reactions might be reduced by taking the corresponding intervention measures according to the influencing factors.

Objective To determine the value of accommodation quotient (AQ) on dysphagia evaluation in the elderly. Methods 40 old cases with dysphagia were assessed with AQ, Kubota Water Swallow Test (WST) and Swallowing Evaluation (SE) before and after 3 weeks of treatment. The patients were divided into 2 groups based on the first AQ assessment: mild group (AQ=1.5~2.5) and serious group (AQ< 1.5). Results There was not significant difference in scores of WST between both groups (P>0.05) but SE (P<0.05). The AQ before treatment moderately correlated with the scores of WST and SE before treatment and improvement (P<0.001), and SE after treatment (P<0.001), but did not correlate with the score of WST after treatment (P>0.05). Conclusion The AQ may indicate the function of swallowing in the elderly, and predict the outcome of dysphagia.

ObjectiveTo investigate the age-related changes in grip strength of the elderly men and compare with the norms of overseas. Methods112 subjects were divided into six groups: 65～69 years old, 70～74 years old, 75～79 years old, 80～84 years old, 85～89 years old, and 90～95 years old. The grip strength was measured with Jamar dynamometer. ResultsThe grip strength of both sides were significantly moderate negative correlated to age (r=-0.681 and -0.68, P<0.001) and stepwise regression analysis showed the age was important clinical factor to consider in determining grip strength in the elderly men （R2=0.468, F=47.951, P＜0.001). The grip strength was declined significantly during the 75～79 and 85～89 years old. ConclusionGrip strength had declined in the elderly men and these losses were significantly related to age. The highest loss in men was in the age over 75. The norms of grip strength overseas were not applicable to Chinese older adults.

ObjectiveTo determine the test-retest reliability of isometric muscle strength measurement for the lower limb with functional squat system （FSS） in elderly people. Methods20 elderly participants were measured the isometric muscle strength in 5 s of each lower limb with FSS, and retested a week later. The maximal voluntary contraction and the average strength of each lower limb were recorded. ResultsThe intraclass correlation coefficient were 0.77～0.88 (P<0.01). ConclusionIsometric muscle strength measurement of the lower limb with FSS shows acceptable test-retest reliability in elderly.

ObjectiveTo determine the value of the five-times sit-to-stand test (FTSST) on assessment of physical performance for older people.Methods65 volunteers participated in this study. 21 of them were evaluated the FTSST twice by the same raters within one week. Test-retest reliability assessed using intraclass correlation coefficients (ICC). 65 volunteers were tested for the FTSST, the Timed "up & go" test(TUGT) and the strength of lower limbs. The Pearson's correlation (r) and stepwise regression analysis was used to examine the relationship between these variables and the FTSST time.ResultsThe FTSST showed good test-retest reliability(ICC=0-91, 95%CI:0-79～0-96). The TUGT, the strength of lower limbs and age were significantly related to the FTSST time (P<0-05). The strength of lower limbs was important clinical factor to consider in determining the FTSST time.ConclusionThe FTSST showed good test-retest reliability and can reflect the physical functional status of older people.

Objective To explore the relationship between the somatosensory evoked potential (SEP) diversification during operation and the short term outcome of ossification of posterior longitudinal ligament (OPLL) of cervical spine. Methods 70 OPLL inpatients from February 2008 to February 2011were included in this study. All patients received anterior cervical operation. According to the diversification of the SEP during surgery, the patients were divided into 2 groups. The preoperative and postoperative JOA scores of the OPLL patients were collected. Results There were 35 patients in the SEP no change group and 30 in SEP improved group. There was no difference in the preoperative JOA scores between them (P>0.05), but was significantly different in the postoperative JOA scores (P>0.05). Conclusion There is some relationship between the SEP diversification during operation and the short term outcome of OPLL of cervical spine.

Objective To study the test-retest reliability of grip strength assessment in the bed-ridden elders above 80 years old. Methods The left and right grip strength of 20 patients who were bed-ridden for more than 1 year, older than 80 years were measured on the lying position with the JAMAR Hand Dynamometer, and they were measured again in the same way by the same conner a week later. Results The intraclass correlation coefficient were 0.985 and 0.970 in the grip strength of left and right hands, respectively. Conclusion The assessment of grip strength showed good test-retest reliability in the bed-ridden elders above 80.
