Objective To investigate the probability and timing of childhood Miller-Fisher syndrome (MFS) progressing to Bickerstaff brainstem encephalitis (BBE), classical Guillain-Barre syndrome (GBS), and pharyngeal-cervical-brachial (PCB-GBS). Methods The clinical data of 128 children with confirmed MFS diagnosis were retrospectively analyzed. Results Among 128 children, 60 cases were simple MFS (ocular muscle paralysis, ataxia, reflexes diminished or disappeared, without limbs weakness and lethargy; laboratory tests suggest cerebrospinal fluid protein-cell separation and/or serum anti-GQ1b antibody positive), 28 cases developed MFS/PCB-GBS (met MFS diagnosis criteria, accompanied by weakness of pharynx, neck and upper limb, weakened or disappeared of upper limb reflex, without weakness of lower limb), 22 cases developed MFS/GBS (met MFS diagnosis criteria, accompanied by weakness of limb), 18 cases developed MFS/BBE (met MFS diagnosis criteria, accompanied by lethargy, pyramidal tract positive). There were no differences in the age at onset, the interval from onset to the start of the treatment, Hughes functional grading, and the percentage of cases having a history of preceding infections, the rate of positive serum anti-GQ1b antibody, the ratio of albumin cytological dissociation in cerebrospinal fluid among 4 groups (P>0.05). The interval from MFS onset to progression to MFS/PCB-GBS, MFS/GBS, or MFS/BBE was within 10 days. Conclusions In children with MFS, 50% developed PCB-GBS, GBS, or BBE, which occurred within 10 days after onset. Clinicians should pay attention to the time window and adjust the medicine rationally.

Objective To establish the oxygen glucose deprivation (OGD)/reoxygenation experimental model of hippocatnpal neurons of rat in vitro, and to try to identify the length of time for producing optimum injury in this model. Method The primary hippocampal neurons of newborn Sprague-Dawley rats were cultured for 7 days and randomly (random number) divided into a control group and OGD groups. The OGD groups were assigned into 1 h, 2 h, 4 h, 6h, 8 h and 10 h subgroups in accordance with different lengths of time for oxygen glucose deprivation. The neurons of OGD groups were placed into a tri-gas incubator containing 0.5% oxygen and the culture medium was substituted with the glucose-free Earle' s balanced salt solution, simulating cerebral ischemia injury in vivo. The morphology of neurons was observed after reoxygenation for 24 hours. The MIT assay was used to determine the rate of survived cells derived from the value of optical density (OD) of cells. The lactate dehydro-genase (LDH) content in culture medium was detected to evaluate the neuron injury. The apoptotic rate of neurons was measured by using flow cytometry. Dunnett-test and Spearman correlation analysis were used to analyze the data with SPSS version 16.0 soft ware package. Results The morphological damage of neurons in OGD groups aggravated gradually, optical density and cell survival rate decreased (rs= -0.961 and rs = -0.966, P <0.01), and the amount of LDH increased (rs = 0.990, P <0.01) with longer duration of exposure to oxygen glucose deprivation, and the rate of neuron apoptosis increased obviously which was significantly statistical difference in com-parison with the control group (P < 0.05). Under the setting of oxygen glucose deprivation for 6 hours, the apop-tosis rate of neurons approximated to 50% . Conclusions The oxygen glucose deprivation/reoxygenation model of rat's hippocampal neurons in vitro was established successfully. From the findings of morphological changes and apoptosis rate of neurons, the oxygen glucose deprivation for 6 hours may be the suitable length of time for inducing neuron injury in this model.

Objective To observe the effects of iodine deficiency and iodine excess on the lipid metabolism in an experimental hypothyroid model of mice and to explore the roles of iodine independent of its role in thyroid hormones. Methods Female Balb/c mice were randomly divided into 6 groups: control, severe iodine deficiency (SID), mild iodine deficiency(MID), normal iodine (NI), 10-fold high iodine (10HI) and 50-fold high iodine(50HI), 10 in each group. The mice in control group were fed with low iodine forage, other mice were fed with low iodine forage containing 0.2% methylthiouracilum. All mice drank deionic water containing different concentrations of potassium iodide(KI). The iodine content in water was 326.79, 0, 196.08,326.79, 385621, 19 542.50 μg/L, respectively. After three months, thyroid hormones in the serum were determined by radioimmunoassay.Also, the blood samples were analyzed for total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesteiol (HDL-C) and low density lipoprotein cholesterol (LDL-C) and measured enzymatically by automatic analyzer. Results①The levels of Tr4 in SID[(21.27 ± 9.63)μg/L], MID[(23.41 ± 3.93)μg/L], NI[(22.57 ±4.66)μg/L], 10HI [(21.07 ± 5.03) μg/L] and 50HI groups [(21.46 ± 5.90) μg/L] were distinctively decreased compared with control group[(42.15 ± 8.26)μg/L, all P < 0.01]. There were no statistical significant differences of TT3 between different groups (F = 0.99, P > 0.05 ). ②The level of TG in 10HI group [ ( 1.17 ± 0.16)mmol/L ] was obviously decreased compared with control [(1.39 ± 0.22 )mmol/L] and NI groups[(151 ± 0.22)mmol/L, all P< 0.05].Both TG and TC in 50HI group[(1.18 ± 0.22), (1.78 ± 0.15)mmol/L] were significantly decreased compared with control [( 1.39 ± 0.22), (2.14 ± 0.37)mmol/L] and NI groups [(1.51 ± 0.22), (2.00 ± 0.15)mmol/L, all P < 0.05].The difference of serum HDL-C and LDL-C between the groups was not significant(F = 0.55,0.54, all P > 0.05 ).Conclusions Dietary iodine plays a role in the metabolism of serum lipids independent of thyroid hormones.Thus, monitoring the amount of iodine intake during sodium restriction should also be taken extremely important for effectively prevention and cure of cardiovascular disease.
