Objective To establish the normal parameters of psychometric measures such as the number connection tests A(NCT-A)and digit symbol tests(DST)in assessment of minimal hepatic en- cephalopathy(MHE).Methods One hundred and sixty healthy volunteers(aged 25 to 64 years;educa- tional level＞9 years)were divided into＜35 ys,35～44 ys,45～54 ys and 55～64 ys groups.All of the healthy volunteers were assessed with NCT-A and DST to establish the normal value of age-related parameters,which can be used for diagnosis of MHE in patients with liver cirrhosis.Two standard devi- ation of the normal mean was used as a diagnostic criterion for MHE.One hundred and six cirrhotic patients were assessed with these parameters.Results The parameters of NCT-A were(25.1?4.6) sec in＜35 ys group,(32.1?6.8) sec in 35～44 ys group,(38.6?7.1)sec in 45～54 ys group or (49.3?6.3)sec in 55～64 ys group.The scores of DST were 49.9?4.7 in＜35 ys group,44.6?4.8 in 35～44 ys group,38.5?5.0 in 45～54 ys group or 35.4?4.7 in 55～64 ys group.Thirty one out of 106 cirrhotic patients were diagnosed as MHE based on these parameters.Conclusion The NCT- A and DST are psychometric assessments for diagnosis of MHE.Age-based normal paramerters of NCT- A and DST are needed to be established.

OBJECTIVETo investigate the growth of craniopharyngioma involving the third ventricular floor with regard to the hypothalamus by detecting expressions of leukocyte common antigen (CD45) and intercellular adhesion molecule (ICAM-1) in the tumor tissue.

METHODSThe expressions of CD45 and ICAM-1 proteins in 30 craniopharyngioma samples with third ventricular floor involvement were detected by SP immunohistochemistry.

RESULTSThe inflammations labeled by CD45 were identified commonly in the craniopharyngioma tissues involving the third ventricular floor. The expression of ICAM-1 was mainly in the inner tumor cells and interstitial cells, but not detected in the basilar tumor cells growing toward the third ventricular floor. Adamantinomatous craniopharyngiomas showed markedly higher CD45 and ICAM-1 expressions than squamous papillary tumors (P<0.05).

CONCLUSIONInflammatory adhesion largely characterizes the growth of the craniopharyngioma tissues involving the third ventricular floor toward the hypothalamus without the tendency of invasion. The difference in the inflammation between the two types of craniopharyngioma may affect the prognosis of the patients.

OBJECTIVETo investigate prospectively the effectiveness of kyphoplasty with SKY bone expander system in treatment of compression fracture of thoracic/lumbar vertebrae and correction of the deformity.

METHODSTwenty-five patients with thoracic/ lumbar vertebral osteoporotic compression fracture were admitted to our hospital between March 2007 and March 2008, and treated by kyphoplasty with SKY bone expander system. Patient's pain status was rated with Visual Analogue Scale (VAS) score system 1 day before and 1 hour, 48 hours, 6 months, 12 months after surgery. In addition, Rolland-Morris and Oswestry disability questionnaires (RDQ and ODI) were used for survey 1 day before and 1, 6, 12 months after surgery. Pre- and post-operative vertebral heights and Cobb's angles were measured based on the X-ray films and statistically analyzed.

RESULTSThere were 27 fractured vertebrae in these 25 patients. After SKY kyphoplasty, the Cobb's angles (9.8 degree ± 9.76 degree) were significantly reduced compared with preoperative angles (17.18 degree ± 9.35 degree P < 0.05), and the average improvement rate was 39%. Patients'pain VAS scores were also greatly improved after operation (P < 0.05). Moreover, postoperative RDQ and ODI scores were significantly smaller than preoperative values (P < 0.05).

CONCLUSIONSKyphoplasty with SKY bone expander system provides an effective method for treating thoracic/ lumbar vertebral osteoporotic compression fracture, with the advantages of small surgical wound and short duration. It can effectively recover the anterior and medial heights of fractured vertebrae (33% and 50%, respectively), reduce the Cobb's angle, quickly alleviate pain and improve patients'quality of life in a relatively short time period.

Objective To investigate the myocardial damage in rats fed with corn from Keshan disease area added with bean puree. Methods Male Wistar rats were randomly divided into 3 groups according to their body weights, and fed with corn, corn from Keshan disease area added with bean puree, corn from non-endemic area. The GSH-Px activity of vena cardalis blood was examined in 1 and 3 months, rats were sacrificed after being fed for 6 months to examine the heart changes with HE stain. Results The three groups of GSH-Px activity were different in 1 and 3 months respectively(F=23.60,72.46, all P<0.01); GSH-Px activity was (181.58±22.15), (44.76±28.59)U/L in rats fed with corn, was (195.03±17.66), (30.38±3.35)U/L in those fed with corn added with bean puree from Keshan disease area, lower than the group fed with corn of non-endemic area[(340.90±95.42), (125.17±13.64)U/L, all P < 0.01]. But the difference of GSH-Px activity between simple corn group and corn adding bean puree groups of Keshan disease area was not obvious(P>0.05). Myocardial damage incidence of the three groups was 3/9,1/9,2/7. Difference among three groups did not have statistical significance(χ2=1.33, P> 0.05). Conclusions Only corn from Keshan disease area may induce myocardial damage pathology change. Adding bean puree into corn does not increase damage.

A(p.G888S)were detected in POLG1 gene.Sequence analysis of parental blood DNA revealed that her father carried L83P and her mother carried G888S.Conclusions The characteristics of clinical manifestation,electrophysiology,pathology and POLG1 gene mutation of the patient were highly consistent with Alpers syndrome.The prominent white matter change and increased immunological factors in CSF were first reported in Alpers syndrome.Alpers syndrome should be considered for those patients whose liver function were severely impaired after exposure to valproic acid.

OBJECTIVETo investigate mutations of ABCD1 gene in X- linked adrenoleukodystrophy (ALD) patients in China.

METHODSPolymerase chain reaction and DNA direct sequencing were employed to analyze the 10 exons of ABCD1 gene in 25 ALD patients.

RESULTSSeventeen mutations in different exons (except exons 4, 9 and 10) were identified in 18 of 25 patients. Most of the mutations were missense mutations, including R182P, G266R, H283D, S404P, N509I, R518G, L520Q, Q556R, S606L and R617C, four (H283D, S40 4P, N509I, R518G) of 10 missense mutations were novel. Also identified were 3 nonsense mutations (W132X, W242X, W595X), 1 dinucleotides deletion mutation (1414 del AG) resulting in frameshift, and 1 base pair deletion at splice acceptor site (IVS5-6 del C). Two synonymous mutations (L516L and V349V) appeared simultaneously in 2 unrelated patients, and no other mutations could be found with them in all 10 exons screened.

CONCLUSIONThere were no hot spot mutations in ABCD1 gene in China. Mutations in gene were found over 70% of patients with ALD in China. The ABCD1 gene mutations identified revealed no obvious correlation between the type of mutation and phenotype.

OBJECTIVEClinical manifestations of opsoclonus-myoclonus syndrome (OMS) in children were summarized and analyzed and the clinical features and therapeutic approaches to OMS were investigated in order to improve its diagnosis and management.

METHODSClinical information on features and management of 6 cases with OMS inpatients being followed up from 2006 to 2007 were collected and analyzed.

RESULTSAmong the 6 cases, one was male and the other five were female. The age at the onset ranged from 12 to 26 months (average 21.0 months). Four of them had history of prior infection. The symptoms were opsoclonus, myoclonus, ataxia, sleep disturbances and behavioural problems in the 6 cases. Urinary DL-3-methoxy-4-hydroxy-acid amygdalin (VMA) was positive in 1 case. Abdominal B-mode ultrasound showed a mild hepatomegaly in 4 cases. The EEG showed abnormal findings such as slow background activity in 3 cases. Epileptiform discharges were found in none of the patients. MRI showed a high signal in medial longitudinal fasciculus and tectospinal tract on T2-weighted image in 1 case. Computerized tomography found L3-4 arachnoid cysts in 1 case and was normal in the others. Adrenocorticotropic hormone (ACTH) was given to all these patients and was effective in all during acute stage. In 2 cases the disease relapsed during follow-up stage.

CONCLUSIONOMS is a rare neurological condition with opsoclonus, myoclonus, ataxia, sleep disturbances and behavioral problems, which might relapse easily and is associated with adverse neurological outcome. ACTH therapy is effective in management of OMS.
