Journal of Clinical Pediatrics 2015;(6):576-578
Objective To investigate the clinical characteristics and diagnostics of Kozlowski type spondylometaphyseal dysplasia (SMDK). Methods The clinical features, laboratory tests and genetic testing of one SMDK case were analyzed. Re-sults A eight-year-old male patient had more than 6 years course of disease. The clinical manifestations were stubby limbs, ifn-gers and toes, varus deformity, knee valgus deformity, scoliosis and lordosis and severe metaphyseal changes. The heterozygous mutations were detected in TRPV4 and NXX3-2 genes. Conclusions Typical clinical features combined with genetic diagnosis facilitate early detection and accurate diagnosis of SMDK.

ObjectiveTo explore the effect of different hypoxic duration on the brain white matter injury.Methods ewborn rats were randomly divided into two groups, normal group (n=24) and model group (n=45). The model group was di-vided into 3 subgroups (n=15) according to the time of hypoxia (50 min, 70 min, and 90 min). The animal model of white matter injury was established by unilateral carotid artery ligation in model group. After different duration of hypoxia, the mortality rate was recorded, the morphological changes of brain pathology was observed by hematoxylin eosin (HE) staining, myelin basic pro-tein (MPB) of white matter was detected by immunolfuorescence staining and motor function was evaluated by climbing slope test.ResultsThe mortality rates signiifcantly increased with prolonged hypoxia. The mortality rate was as high as 60% in 90 min subgroup. The HE staining showed that there were no obvious injury in 50 min subgroup, selective white matter injury on the operative side appeared in 70 min subgroup, and a wide range of infarction of white matter, hippocampus, and cortex appeared in 90 min subgroup. MBP semi-quantitative scores of white matter injury were higher in 70 min subgroup (3.89 ± 0.47) and 90 min subgroup (4.72 ± 0.57) than that in the normal group (0.06 ± 0.24), the difference was statistically signiifcant (P <0.05). In climb-ing slope test, the subgroups had different degrees of motor dysfunction on affected side with 90 min subgroup being the most serious.ConclusionsWhite matter injury model could be established by unilateral carotid artery ligation, and different hypoxic duration signiifcantly affects the range and degree of injury.

BACKGROUND:Lingo-1 has been identified as a negative regulator of oligodendrocyte differentiation and myelination, which may be closely related to the white matter damage, but there is no systematic report on the dynamic changes of Lingo-1 after white matter damage.
OBJECTIVE:Toexplore the dynamic expression of Lingo-1 at different time points after white matter injury in newborn rats.
METHODS:Seventy-eight Sprague-Dawley rats aged 3 days old were equaly and randomly divided into sham operation group and model group. In the model group, models of white matter injury were established by unilateral ligation of the right common carotid artery combined with hypoxia. In the sham operation group, the right common carotid artery was isolated only, without ligation or hypoxia.
RESULTSAND CONCLUSION:At 7 days after model induction, hematoxylin-eosin staining and immunohistochemical staining for myelin basic protein showed that a selective white matter injury was seen at the injury site of a rat model, suggesting successful model establishment. Fluorescent quantitative PCR and western blot assay results demonstrated that the expression levels of Lingo-1 mRNA and protein were significantly up-regulated at 1 day and reached a peak at 7 days post-surgery. After 7 days, above expression wasgradualy decreased and the up-regulation of Lingo-1 protein lasted to the 28 days post-surgery compared to the sham operation group. These results show that Lingo-1 protein was closely related to the brain white matter injury.

Posterior reversible encephalopathy syndrome is a clinical imaging syndrome associated with multiple pathogenic factors.The main clinical manifestations were headache,seizures,psychotic symptoms,visual disturbance,disturbance of consciousness,etc.The parieto-occipital reversible white matter lesions are the main manifestations of the imaging.If this disease can be diagnosed and treated in time,the clinical symptoms and imaging changes of most patients can be disappeared.If the diagnosis and treatment cannot be obtained in time,it may happen some irreversible damage,serious and even life-threatening,so it is very important to strengthen the understanding,diagnosis and treatment of this disease.At present,the pathogenesis of the disease is still not clear,now reviewed its pathogenesis and imaging manifestation in order to strengthen the clinician's understanding of the disease's pathophysiological mechanism and improve the level of diagnosis.

OBJECTIVE:To establish a method for the content determination of Aciclovir cream. METHODS:Centrifugal parti-tion chromatography(CPC)was conducted. The solvent system was hexane-acetonitrile-water(2∶1∶1,V/V/V),the injection vehicle was an aqueous solution of 5%Tween 80 and the volume was 1.0 ml;the flow rate was 5 ml/min;the wavelength was 254 nm. RE-SULTS:There was a good linear relationship between quality concentration and peak area in the range of 0.012 7-0.126 7 mg/ml (r=0.998 7). The RSD of precision,stability and reproducibility tests was all no more than 2.0% and the average recovery was 97.34%(RSD=0.90%,n=9). CONCLUSIONS:The method is with high precision and accuracy,and can be used for the content determination of principal components of Aciclovir cream.

AIM: To investigate the relationship between morphologic changes in neuron or neuroglial cells and expression of tumor necrosis factor ? (TNF-?) and c-Myc in cortex after focal cerebral ischemia/reperfusion in MCAO rats. METHODS: The focal cerebral ischemia/reperfusion model was established by intraluminal thread occlusion of the middle cerebral artery (MCAO). The middle cerebral arteries of rats were occluded for 2 hours and reperfused for 1, 3 and 7 days. Using the techniques of immunohistochemical staining and optical microscopy, the morphologic changes in neuron or neuroglial cells were observed in the cortex of frontal or parietal lobe; the cell types which dynamicaly expressed TNF-?, c-Myc in the different period were also observed. RESULTS: The degeneration or necrosis of neuron or neuroglial cells were observed at the center of infarction, it was very serious at 3 d after reperfussion. Astrocyte and microglial cell proliferation were observed at the broder of infarction. TNF-? and c-Myc positive cells, most of which were astrocytes and microglial cells, increased significantly at 3 d after reperfusion. CONCLUSION: TNF-? and c-Myc may play an important role in the regulation of neuron or neuroglial cells after focal cerebral ischemia with reperfusion. [

The diabetes is mainly treated by the oral administration of western medicines at present. Despite their rapid curative effect, there have been still many reports for the western medicines about their clinical adverse reactions, failure of effective prevention and treatment of complications and drug resistance. Hence, they are not suitable for long-term administration. Traditional Chinese medicines have a long history in treating diabetes mellitus (DM) , which is commonly known as Xiaokezheng in the theory of traditional Chinese medicines. In recent years, many scholars have taken extracts from traditional Chinese medicines or separated active constituents as the study objects in the expectation of developing new-type drugs for treating and preventing diabetes. Therefore, a large number of study reports have been emerged in this field. Due to their significant glucose-reducing effect and specific effect in treating complications of diabetes, traditional Chinese medicine Gardeniae Fructus and its iridoid component geniposide shall be given full attention. This paper summarized the advance in studies on the curative effect and action mechanism of Gardeniae Fructus and geniposide in preventing and treating diabetes.

Objective To evaluate the role of CT in manifestations and differential diagnosis of mass-like hepatic lesion. Methods 310 cases of mass-like hepatic lesion, including hepatocellular carcinoma, metastasis, hemangioma, abscess, cyst, hydatidosis were included. The CT findings including mass location, number, edge and the degree of contrast-enhancement were analyzed. Results On CT, mass-like lesions manifested single or multiple lesions with low density, with sharp edge or without, with contrastenhancement in various degrees or without. In our study, there were characteristic CT manifestations for hepatocellular carcinoma, metastasis tumor, hemangioma, abscess, cyst and hydatidosis. Conclusion The diagnosis and differential diagnosis can be made correctly with CT manifestations in most of mass-like hepatic lesions.
