The 81st case:a 58 years old male patient presented with later motor milestone, frequent falling for 55 years, weakness of lower limbs for 13 years, upper limbs weakness for 3 years / 中华神经科杂志

A 58-year-old man who presented with progressive proximal weakness and elevated serum creatine kinase levels was found to have typeⅢa glycogen storage disease. Except for a history of later motor milestone in childhood, he was healthy and lived a normal life. There was no hypoglycemia, hepatomegaly or growth retardation. Muscle weakness was not apparent until the fourth decade. Scoliosis and mild hypertrophy of cardiac ventricular septum were detected. Muscle biopsy was performed which revealed amount of glycogen depositing. A novel homogenous splicing mutation was found in AGL gene.

Correlation of CXCL10 levels in plasma and cerebrospinal fluid with clinical course in patients with multiple sclerosis evolution / 中华神经科杂志

Objective To investigate the evolution of CXCL10 in blood plasma and cerebrospinal fluid (CSF) during relapses of multiple sclerosis (MS),and the correlation between these and the clinical neurological dysfunction.Methods Fifty-three patients with definite MS during relapsing state (relapsing MS group) diagnosed by the McDonald criteria;fifty-three patients with definite MS during remitting state ( remitting MS group);thirty-two patients with non-inflammatory neurologic disease ( NIND group) and fiftythree healthy controls (NC group) were enrolled in the study.Each patient clinical status was evaluated with the Expanded Disability Status Scale ( EDSS).Plasma and CSF levels were analyzed by enzyme-linked immunoassay.Results ( 1 ) The CXCL10 level in plasma in relapsing MS group elevated significantly between the 2nd ( (601 ± 365 ) pg/ml,t = - 2.898,P = 0.001) and the 4th ( (575 ± 297 ) pg/ml,t = -2.651,P=0.003) week after relapsing;GXL10 in CSF (n =32) did not changed significantly in the 4th week after relapsing( (1807 ±803) pg/ml).(2) The CXCL10 level in plasma in relapsing MS group were significantly higher than that in the healthy control group ((248±130) pg/ml,(=4.895,P=0.000) and remitting MS group ((287 ±118) pg/ml,t = 3.555,P = 0.001 ).( 3 ) The CXCL10 level in CSF in relapsing MS group (( 1774 ± 604) pg/ml) was significantly higher than that in NIND group ( ( 122 ± 114) pg/ml,t= 15.192,P =0.000).(4) The CXCL10 level in plasma in relapsing MS group had correlation with that in CSF (r=0.792,P=0.001).The CXCL10 level in CSF in relapsing MS group had correlation with EDSS scores (r = 0.526,P = 0.002 ).Conclusions The CXCL10 level in plasma might be implemented as a paraclinical marker of disease activity in MS.The CXCL10 level in plasma of MS may be relevant to that in CSF.The CXCL10 level in CSF of MS may indicate the clinical neurological dysfunction.
