In recent years, nonalcoholic fatty liver disease (NAFLD) has increased because of the growing prevalence of obesity and overweight in the pediatric population. It has become the most common form of chronic liver diseases in children and the related research on NAFLD is expanded. The "two-hit" and "multiple hit" hypothesis have been widely accepted, and some research has shown that genetic, diet structure and environmental factors appear to play a crucial role in the development of pediatric NAFLD. Though it is expected by researchers, there is not an available satisfactory noninvasive marker for the diagnosis of this disease. Fortunately, some new non-invasive prediction scores for pediatric NAFLD have been developed. There is currently no established special therapy, and lifestyle intervention should be adequate for most cases of NAFLD in children. This article reviews the advances in the current knowledge and ideas concerning pediatric NAFLD, and discusses the diagnosis, perspective therapies and scoring methods for this disease.

Objective To explore therapeutic effects and mechanisms of radical scavenger edaravone on experimental cerebral hemorrhage.Methods Two hundred-forty male SD rats were divided randomly into four groups:control group,cerebral hemorrhage group,edaravone treatment group before operation (A) and edaravone treatment group after operation (B).Experimental cerebral hemorrhage model was made according to the method reported by Rosenberg.Water quantity contained in brain and nervous missing sign were observed,meanwhile the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in brain tissue were measured.Results Compared with cerebral hemorrhage group,nervous missing sign and water quantity contained in brain obviously changed in edaravone treatment group (P

This study was aimed to explore differential effects of various sections of the velvet antler on promoting cell proliferation in vitro. The NRK-49F cell line from rat kidney fibroblasts was used as the cell model. The cell proliferation rates of the water extracts from the upper, middle and lower section of fresh velvet antler were measured by the MTT method. BCA method was used in the detection of protein concentration. The SDS-PAGE method was used in the analysis of difference composition of the sample protein. The results showed that soluble protein content of the upper, middle and lower section were 17.89, 16.04 and 6.89 mg·mL-1, respectively. From the top to the base, the soluble protein content of velvet antler was decreased. After 24 h treatment, when the protein concentration of the upper and middle section samples of the velvet antler were 800 μg·mL-1 and 600 μg·mL-1, the cell proliferation promoting rates reached the maximum, which were 66.76% and 64.36%, respectively. And when the lower section sample of the velvet antler was 1 000 μg·mL-1, the cell proliferation promoting rates reached the maximum, which was 58.87%. After 48 h treatment, when the upper and middle section samples of the velvet antler were 800μg·mL-1, the cell proliferation promoting rates reached the maximum, which were 219.56% and 215.86%, respectively. And when the lower section sample of the velvet antler was 1 000 μg·mL-1, the cell proliferation promoting rates reached the maximum, which was 169.20%. The velvet antler on the proliferation of cells was much better than the 10% fetal bovine serum. The figure of SDS-PAGE showed the slight difference in the protein composition of three part of the velvet antler. It was concluded that all samples had promoting effects on cell proliferation with concentration-depen-dent, and the main protein in different part of the velvet antler had minor differences.

Objective To study the gene homology of intestinal colonized and infectious bacteria in ICU patients to provide the epidemiological and molecular biological basis for formulating the control measures of multi resistant bacterial hospital infection. Methods The multi-drug resistant colonized bacteria isolated from the anal swabs and the same multi-drug resistant bacteria isola-ted from the clinical samples in the same patients were matched.The Diversilab automatic repetitive extragenic palindromic(REP)-PCR typing system was adopted to analyze the gene homology of multi-drug resistant colonized bacteria and infectious bacteria in the intestinal tract.Results 4 pairs of multi-drug resistant colonized bacteria and the same multi-drug resistant bacteria isolated from the clinical samples on admission in the same patients were selected and performed the homology detection,2 pairs had the ho-mology and 2 pairs had no homology;4 pairs of multi-drug resistant colonized bacteria and the same multi-drug resistant bacteria isolated from the clinical samples in the patients with hospital infection were performed the homology detection,4 pairs all showed the homology.Conclusion The multi-drug resistant colonized bacteria and the infectious bacteria in ICU patients have the homolo-gy.The multi-drug resistant colonized bacteria can cause the occurrence of hospital infection,so their management should be strengthened in clinic.

Objective To study the mechanism of marcosomia by investigating insulin-like growth factor 2(IGF_2)imprinting status,expression level and the promoter usage in the placenta of macrosomia. Methods We selected heterozygous cases for Apa Ⅰ polymorphism in exon 9 of IGF_2 gene and then analyzed its imprinting status in 168 placentas of macrosomia and normal pregnancies.IGF_2 transcription levels and promoter usages in macrosomic and normal placenta were evaluated by using semi-quantitative RT- PCR assay.Results Thirty specimens of macrosomic placenta and 30 of normal placenta were identified as heterozygous for IGF_2.All of the heterozygous specimens showed maintenance of imprinting.The expression of placental IGF_2 mRNA(2.2?1.2)was significantly higher in macrosomia than that of normal weight group (1.6?0.6,P 0.05).Conclusion It is possible that over expression of IGF_2 in placenta contributes to macrosomia while the promoter usage and imprinting status are not associated with macrosomia.

Exosomes are membrane vesicles secreted by cells into the extracellular environment. Exosomes are a new cell component in the treatment of spinal cord injury. Exosomes are secreted by mesenchymal stem cells have anti-apoptotic, anti-inflammatory and pro-angiogenic effects in the treatment of spinal cord injury, which play a key role in nerve cell-cell communication and can delivery exogenous genetic material. Exosomes can penetrate blood-brain barrier and are more stable than their parent cells, reducing the safety risks in the administration of viable cells.

AIMTo investigate the effects of melatonin (MT) on histology and behavioral tests during global cerebral ischemia-reperfusion in gerbils.

METHODSGlobal cerebral ischemia was induced by occluding the bilateral common carotid arteries for 10 min in gerbils. Three doses of MT were administrated intraperitoneally 30 min prior to the onset of ischemia. Locomotor activity was measured by using the open field method 3 and 7 days after the ischemic episode. T maze test was carried out 4, 5 and 6 days after ischemia to assess the working memory of gerbils. Neuronal damage was assessed in CA1 pyramidal layer of gerbil hippocampus and evaluated 7 days after ischemia.

RESULTSMT significantly reversed the locomotor activity increases, ameliorated learning and working memory deficit, and reduced the extent of CA1 hippocampal pyramidal cells injury after transient global cerebral ischemia in the Mongolian gerbil.

CONCLUSIONMT provides significantly protective effect against both histological and behavioral consequences of global cerebral ischemia-reperfusion injury in gerbils.
