Objective To study the correlation between isokinetic parameters and modified Ashworth Scale (MAS) in ankle spasticity as-sessment. Methods 18 stroke patients (spasticity group) and 16 healthy subjects (control group) in our hospitals from August 2014 to March 2015 were included. MAS was used to assess the ankle muscular tension. The ankle passive movement of both groups was measured with BIODEX isokinetic motor assessment system under 10 °/s, 60 °/s, 120 °/s, 180 °/s, 240 °/s. The peak torque (PT), peak torque/body weight (PT/BW), average torque (AT), and slopes of the linear regression curve of torque-velocity (SLOPE) were recorded. The correlation of the isokinetic paramenters and the MAS were tested with Spearman correlation analysis. Results The PT, PT/BW and AT were higher in the spasticity group than in the control group (P<0.05). And they increased as the angular velocity increased, and slowed after 120 °/s. The corre-lation coefficient of MAS and PT, PT/BW, AT, SLOPE were from 0.3043 to 0.7632 (P<0.01). Conclusion The isokinetic parameters were speed-dependent and closely related to MAS. 120 °/s was of the highest sensitivity, and the SLOPE under this anglular velocity was highly correlated with MAS.

AIM: To evaluate the repeatability and reproducibility of thickness profile measurement of intra-retinal layers determined by an automated algorithm applied to OCT images from Cirrus optical coherence tomography (OCT) instrument.METHODS: In this prospective cross-sectional study,retinal thickness images at 6mm×6mm around fovea were obtained from 86 eyes of 43 normal subjects with Cirrus HD-OCT instrument.The retinal images from patients were analysis by Cirrus automated algorithm GCA software,including ganglion cell layer and inner plexiform layer(GCIPL).During this study,operator A would make 2 times measurements to all patients,after that operator B would make another 2 times measurements by Repeat scan model.All the data,including GCL average thickness,min thickness,12 clock average thickness,2 clock average thickness,4 clock average thickness,6 clock average thickness,8 clock average thickness and 10 clock average thickness were measured by SPSS 15.0 software.Standard deviation (SD),coefficient of variation (CV) and interclass correlation coefficient (ICC) were calculated from the results of three-times tests by different examiner to evaluate the repeatability and from the results of two different examiners to assess the reproducibility.Written informed consent was obtained from each subject prior to any medical procedure.RESULTS: The average GCIPL thickness of OD was 85.12±3.95μm;the minimum average GCIPL thickness was 83.21±4.41μm;the standard deviation of OD in clock map was from 3.79μm to 4.84μm;CV(95%CI) was between 0.26 and 0.93;ICC was from 0.939 to 0.989.The average GCL+IPL thickness of OS was 84.65±8.73μm;the minimum average GCPL thickness was 81±13.08μm;the standard deviation of OS in clock map was from 8.24μm to 10.56μm;CV(95%CI) was between 0.92 and 4.94;ICC was from 0.264 to 0.968.CONCLUSION: Cirrus HD-OCT GCA software with automated algorithm can offer accurate and repeatable thickness profile of OCT retinal image.GCA is a useful and reliable approach to the measurement of intra-retinal layer thickness,which may improve the diagnosis and monitoring of retinal diseases.

Measuring the content of soluble reducing sugar, total sugar, soluble protein, guanosine, alkaloids, and succinic acid of Pinellia ternata tuber were measured by anthrone-sulfuric acid colorimetric method, Coomassie brilliant blue method, RP-HPLC, reverse potentiometric titration, acid dye colorimetry, respectively. The result showed that yellow light could promote the growth and development of P. ternata and increase the content of soluble reducing sugar, total sugar, alkaloids, and succinic acid. Under blue light could promote the content of soluble protein and guanosine. Red and yellow light increased the content of chlorophyll a and chlorophyll b, contrastively blue light reduced the content of chlorophyll a and chlorophyll b. White film through the most uniform spectrum was most conducive to the synthesis of chlorophyll a. As single film, blue film, yellow film were more conducive to the synthesis of chlorophyll a, green film and red film had been relatively beneficial to the synthesis of chlorophyll b. Bulbil formed the largest number and the biggest propagation coefficient of P. ternata under red light showed that it could increase the production of P. ternata under red light.
