1.The development of evaluation in cerebral palsy
International Journal of Pediatrics 2010;37(1):88-91
Cerebral palsy (CP) is a group of syndrome caused by a non-progressive brain injury that occurs from before birth to 28 days after birth. The principal symptoms of CP are abnormal centrocinesia and irregular posture, or accompanied by intelligence disorders, seizures, dystropy, sensory impairments and other dysfunctions. To evaluate the function of children with cerebral palsy can assess disfuction level,judge clinical classification, estimate prognosis, and more importantly guide to establish treatment plan and evaluate therapeutic efficacy. At present, there are no unified standards to evaluate CP at home and abroad, So this article will overview evaluation methods of CP commonly used in recent years.

With regard to the bounded linear continuous-time system, a universal chaotic anti-controlling method was presented on the basis of tracking control. A tracking controller is designed to such an extent that it can track any chaotic reference input, thus making it possible to chaotify the linear system. The controller is identical in structure for different controlled linear systems. Computer simulations proved the effectiveness of the proposed method.

Objective To investigate the effect of intrathecal (IT) administration of L-NAME , a nonselective nitric oxide synthase (NOS) inhibitor, on c-fos expression in spinal cord induced by neuropathic pain. Methods Eighty-four female SD rats weighing 220-310g, which showed no signs of never injury 3 to 4 days after IT catheterization with the tip of catheter reaching the lumbar region, were divided into 4 groups at random: group A received IT 0.9% NaCl 10?g 15min before sham operation ( n = 16); group B received IT 0.9% NaCl 10?l 15min before ligation of sciatic nerve ( n =24); group C received IT L-NAME 10?l (250?g) 15min before sham operation ( n = 16); group D received IT L-NAME 10?l (250?g) 15min before ligation of sciatic nerve (n =24) . The animal in each group were further divided into 4 subgroups ( n = 4-6) and sacrificed on 1st, 3rd, 7th and 14th day after operation. In addition 4 rats which had received no operation of any kind were sacrificed and served as control. The c-fos expression in ipsilateral dorsal horn of spinal cord was detected by immunohistochemistry technique. Results In normal rats in control group (no IT catheterization, no operation) there were only a few fos-positive neurone (3.4? 0.9). The c-fos expression in the ipsilateral dorsal horn of spinal cord greatly increased both in group A and B. In group B there were more fos-positive neurons (FLIN) in the ipsilateral dorsal horn on the 3rd, 7th and 14th day as compare with group A. With pre-emptive intrathecal administration of L-NAME, the increase in ipsilateral c-fos expression induced by ligation of sciatic nerve was inhibited. In group D the number of fos-positive neurons in ipsilateral dorsal horn decreased by 53.8%, 57.1% and 43.2% on the 3rd, 7th and 14th day after operation as compare with group B. On the 1st day afteroperation there was no difference-in FLIN in the ipsilateral dorsal horn between group B and D. Conclusion Nitric oxide plays an important role in mediating the neuropathic pain which can be effectively attenuated or prevented by pre-emptive IT administration of L-NAME.

Objective To investigate the effect of pre-emptive intrathecal (IT) administration of L-NAME, a non-selective nitric oxide synthase (NOS) inhibitor on calcitonin gene-related peptide (CGRP) expression in the dorsal horn of spinal cord in a rat model of neuropathic pain. Methods Ninety-six female adult SD rats weighing 220-310 g were randomly divided into four groups with 24 animals in each group : group A received IT 0.9% NaCl 15 min before sham operation; group B received IT 0.9% NaCl 15 min before right sciatic nerve ligation; group C received IT L-NAME 250 mg in 10?l 15 min before sham operation and group D received IT L-NAME 250 ?g in 10 ?l15 min before sciatic nerve ligation. The animals were anesthetized with intraperitoneal pentobarbital 50 mg?kg-1. A PE-10 catheter was placed in subarachnoid space with the tip of the catheter reaching the lumbar enlargement region. The animals were allowed to recover for 3-4 days and only those waking normally were used in the study. Right sciatic nerve was exposed and four loose ligatures were placed on the sciatic nerve according to the method described by Bennet. In sham operation the sciatic nerve was exposed but not ligated. The animals were sacrificed on the 1 st, 4 th, 7 th and 14 th day after operation. The lumbar segment of spinal cord was immediately removed. The CGRP expression in the ligated-side dorsal horn was assessed with immuno-histochemistry technique. Results In group B and D CGRP expression in the ligated side dorsal horn was significantly increased on the 4th, 7th and 14th day after operation as compared with that in group A. There was no significant difference in the CGRP expression in the ligated side dorsal horn between group A and C as well as between B and D. Conclusion Pre-emptive IT administration of L-NAME cannot inhibit the increase in CGRP expression in dorsal horn induced by peripheral nerve injury, suggesting that the neuropathic pain mediated by NO is not related to the release of calcitonin gene-related peptide.
