OBJECTIVE To evaluate the value of central compartment neck dissection for cN0 papillary thyroid carcinoma.METHODS The clinical data of 46 cases with cN0 papillary thyroid carcinoma in our hospital from Jan.1999 to June 2004 were retrospectively studied.The level Ⅵ lymph nodes were removed during the operation.RESULTS In 46 cN0 cases,there were 11 cases(23.9 %) pathologically proved lymph nodes metastasis after operation.Four patients developed neck recurrence and underwent neck dissection.CONCLUSION It is necessary to probe the level Ⅵ lymph nodes during the operation for cN0 papillary thyroid carcinoma patients.

Objective To compare the effect of electro-acupuncture(EA) and warm-needle moxibustion(WNM) on the foot three-dimensional gait time-space parameters and surface electromyography of post-stroke patients with flaccid paralysis. Methods A total of 61 patients were randomly divided into EA group (N=30) and WNM group(N=31). Both groups were given post-stroke conventional treatment, and additionally EA group received EA while WNM group was given WNM. Before treatment and after 2 treatment courses, we detected the foot three-dimensional gait time-space parameters of pace race, stance phase, swing phase, bilateral stance phase, and step length, and surface electromyography parameters of root mean square(RMS), integrated electromyogram (iEMG) and co-contraction ratio(CR) of tibialis anterior muscle and gastrocnemius at the state of maximal isometric voluntary contraction(MIVC). Results(1) After treatment, the foot three-dimensional gait time-space parameters of the two groups were improved in various degrees (P<0.05 or P<0.01 compared with those before treatment) , and the improvement of EA group was superior to that of WNM group (P < 0.05). (2) After treatment, the RMS and iEMG of the gastrocnemius and tibialis anterior muscle as well as CR of dorsal extensor at MIVC state were improved in various degrees (P < 0.05 or P < 0.01 compared with those before treatment) , and the improvement of EA group was superior to that of WNM group(P < 0.05 or P < 0.01). Conclusion WNM exerts better effect on improving the parameters of three-dimensional gait time-space parameters and surface electromyography of post-stroke patients with flaccid paralysis than EA.

Objective To observe the clinical effect of monosialotetrahexosyl ganglioside sodium injection (GM1) on spastic cerebral palsy. Methods 98 children with spastic cerebral palsy were randomly divided into control group (n=50) and treatment group (n=48). Both groups received Bobath approach, and the treatment group received GM1 in addition. They were assessed with Functional Independence Measure for Children (WeeFIM), Gross Motor Function Measure (GMFM) and Gesell Development Schedule (GDS) before and after 90 days of treatment. Results The scores of WeeFIM, all the dimensions of GMFM and the gross motor, fine motor, personal-social and adaption of the GDS improved in both groups after treatment (P<0.05), and improved more in the treatment group than in the control group (P< 0.05). Conclusion GM1 may further improve the recovery of function for children with spastic cerebral palsy.
