Objective To compare the effects of neutral posture training (NPT) and gas resistance training on balance and motor func-tion in stroke patients. Methods From June, 2014 to February, 2016, 44 hemiplegic patients were randomly divided into control group (n=22) and experimental group (n=22). The control group received conventional decubitus trunk muscle training and sitting gas resistance train-ing. The experimental group received NPT. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and Berg Balance Scale (BBS) before and after training. Results There was no significant differ-ence in the scores of FMA-UE, FMA-LE and BBS between two groups (t<0.962, P>0.05). The scores significantly increased after training in both groups (t>12.248, P<0.001), and were higher in the experimental group than in the control group (t>1.972, P<0.05). Conclusion The NPT could improve the motor and balance function of stroke patients, rather than gas resistance training.

ObjectiveTo study the expression of telomerase of fibroblasts in the formation and development of scar,and to investgate the relationship between the telomerase activity and the formation and development of scar.MethodsExpression of telomerase was detected by immunohistochemical techniques in 18 specimens from granulation tissue,17 keloid,16 specimens from hypertrophic scar,28 specimens from mature scar,32 specimens from normal skin,and SPSS16.0 statistics software was used to analyze the relationship between telomerase and scar.Results It was shown that the positive expression rate of telomerase in the granulation tissue group was 94.4 ％,that in the keloid group was 58.8 ％,that in the hypertrophic scar group was 18.8 ％, and that in the mature scar and in the normal skin was zero. comparisons between groups,in addition to the normal scar group and normal skin group,other groups were statistically significant differences.ConclnsionsScar formation is a process with multi-factor participation,while telomerase activation is an important factor. Detecting telomerase activity in the development process of scar formation may determine the prognosis.Through the control of telomerase activity in the pathogenesis of scar may become a new approach of scar treatment.

ObjectiveTo determine the optimal timing of antenatal taurine supplementation to improve neuron and neural stem cell proliferation in fetal rats with intrauterine growth restriction.Methods Twenty-five pregnant SD rats were randomly divided into five groups (five rats in each group): group A was the control group, group B to E were the fetal growth restriction (FGR) model groups with low-protein diet during the experiment, group C, D, and E were supplemented with taurine [300 mg/(kg·d)] at day 9, 11 and 15, respectively. The birth weight of newborn rats was measured after natural delivery. The rats with body weight two standard deviations lower than the average weight in group A were diagnosed as FGR. There were five litters of newborn rats in each group, and two were randomly selected from each litter, resulting in ten newborn rats in each group. Proliferating cell nuclear antigen (PCNA) and fatty acid binding protein 7 (FABP7) positive cell expression in newborn rat brain tissues were detected by immunohistochemistry. Single factor analysis of variance, LSD tests were used for statistical analysis.ResultsThe average birth weight of newborn rats in group A, B, C, D and E were (6.61±0.45), (4.65±0.23), (5.37±0.17), (5.74±0.21), and (5.00±0.24) g, respectively. Average birth weight was lower in group B than in group A (t=2.447), higher in group D and E than in group B (t=2.306 and 2.306), higher in group D than in group C and E (t=2.306 and 2.306), and the differences were statistically significant (allP<0.05). The positive expression of PCNA in the brain of neonatal rats was mainly located in the nucleus. The number of PCNA positive cells in each high power field (×400) in group A, B, C, D and E was 31.03±5.38, 46.49±4.38, 59.65±5.37, 67.76±5.84, and 53.53±6.94, respectively. The number of PCNA positive cells in group B was higher than that in group A (t=2.110), higher in groups C, D and E than in group B (t=2.110, 2.110 and 2.131), higher in group D than in group C and E (t=2.101 and 2.110), and the differences were all statistically significant (allP<0.05). The positive expression of FABP7 was mainly located in the cytoplasm of neonatal rat brain. The integral optical density (IOD) in group A, B, C, D, and E was 451 733.1± 141 452.3, 207 232.2±60 525.2, 333 766.6±68 412.1, 380 647.4±131 145.9, and 278 967.1±127 630.7, respectively. The IOD in group B was lower than that in group A (t=3.165,P=0.000), higher in groups C, D and E than in group B (t=5.272, 7.132, 2.950), and the differences were statistically significant (allP<0.05). Although the IOD in group D was higher than that in group C, the difference was not significant (t=1.953, P>0.05). The IOD in group D was higher than that in group E, and the difference was statistically significant (t=4.182,P<0.05).ConclusionsAntenatal taurine supplementation can promote neuron and neural stem cell proliferation in rats with FGR. The effect is most obvious on the 11th day of pregnancy, and may lead to the promotion of brain development.
