The metabolic syndrome is composed of various metabolic disorders,which is associated with cardiovascular disease.Dyslipidaemia in the metabolic syndrome in children and adolescents,as defined by American Academy of Pediatrics and Chinese Society of Pediatrics,is characterised by elevated triglycerides and non-high-density lipoprotein cholesterol as well as low high-density lipoprotein cholesterol concentrations.Good evidence confirms that dyslipidaemia in children plays a vital role in the development of adulthood disease,such as atherosclerosis and hypertension,also closely related to metabolic syndrome,insulin resistance and hyperglycemia.Here we reviewed the the role of dyslipidemia in metabolic syndrome in children and adolescents.

Objective:To determine the expression level of bone morphogenetic proteins-4 (BMP-4) and the relationship between the expression of BMP-4 and the clinical/pathological parameters in patients with gastric cancer. Methods:Using im-munohistochemical staining technique ,expressions of BMP-4 were investigated in different tissues from 90 gastric cancer specimens and 30 specimens from normal gastric mucosa as control. ResultS:The positive rate of BMP-4 was 23. 3% (21/90) in gastric cancer and 3. 3% (1/30) in normal gastric mucosa. The expression of BMP-4 in gastric cancer was closely related with locus, serosa infiltration,cell differentiation and lymph node metastasis (P

AIM: To develope a reversed-phase high performance liquid chromatographic method for the quantitative determination of chlorogenic acid and caffeic acid in Shegan Kangbingdu Injection. METHODS: The operation was carried out in the Kromasil ODS column with the mobile phase consisting of a mixture of water-methanol-acetonitril aceti acid(95∶10∶5∶2,v/v),in which the flow rate of 1.0 mL/min and UV detection wavelength at 326 nm were set to determine the contents of chlorogenic acid and caffeic acid. RESULTS: There were good linear relations between the concentrations and the peak-areas of chlorogenic acid and caffeic acid.The relative standard deviation of peak areas for chlorogenic acid or caffeic acid were 0.60%,0.32%,respectively.The two kinds of standard solutions were both stable in 16 h(RSD=0.54% for CGA,0.11% for CFA).The average recovery was 100.1%,99.6% for CGA,CFA,repectively.The detectable limit(S/N=3)was 0.012,0.020 mg/L,and the quantitative limit (S/N=10) was 0.037,0.052 mg/L,repectively. CONCLUSION:The method is simple,sensitive,rapid and accurate,and can be used for the quality control of Shegan Kangbingdu Injection

AIM: To observe the dynamic changes of plasma levels of nitric oxide(NO) and endothelin (ET-1) in portal veins of the rats during prehepatic portal hypertension, and investigate the role of them in hyperdynamic circulation. METHODS: The models of prehepatic portal hypertension were established in Sprague-Dawley rats by means of partial portal vein ligation (PVL). The plasma levels of nitrite/nitrate (NO - 2/NO - 3) and ET-1 in the portal veins were detected by the method of nitric reductase and radioimmunoassay, respectively. In this study, rats were divided into normal, sham operation (SO) and PVL group. SO and PVL rats were divided into several subgroups according to different time after operations. Meanwhile, the changes of several hemodynamic indexes in these rats were also measured. RESULTS: The levels of NO - 2/NO - 3 were significantly increased and ET-1 were significantly decreased in rats at different time after PVL compared with normal control, whereas the hemodynamic indexes changed accordingly. CONCLUSION: The portal hypertensive rats are in hyperdynamic circulatory state (HCS). NO and ET-1 may play an important role in the induction and maintenance of HCS.

Objective To investigate the effect of synthetic small interfering RNA (siRNA) targe- ting plasminogen activator inhibitor-1 (PAI-1) on the biological characters of hepatic stellate cells (HSCs).Methods Synthetic siRNA targeting PAI-1 was transfected into HSC-T6 by lipofectamine package.Negative siRNA transfection and no transfection were used as negative control and blank con- trol respectively.After incubation with siRNA,total RNA and protein of HSC-T6 cells were extracted. The expression of PAI-1 gene was detected by reverse transcription-polymerase chain reaction and immuno- cytofluorescent.The proliferation of HSC-T6 was determined using MTT assay.HSC-T6 cycle and apoptosis were measured by flow cytometry.Content of typeⅠandⅢcollagen in the supernatants were determined by enzyme linked immunosorbent assay.Results The expressions of PAI-1 mRNA and pro- tein were markedly down-regulated in siRNA-transfected HSC-T6.The proliferation of HSC-T6 was inhibited by transfection of siRNA.The level of typeⅠcollagen in the supernatants decreased by (20.71?8.40)% and (37.97?6.40)%,repectively(F=42.69,P=0.0001) compared to those in the negative control at 48 and 72 hours.The level of typeⅢcollagen decreased by (35.98?4.60)% (F=105.52,P= 0.0001) at 72 hours.Conclusion Inhibition of PA-1 by siRNA may have a potential effect in prevention and treatment of hepatic fibrosis by inhibiting proliferation,promoting apoptosis of stellate cells.Therefore,it decreases the synthesis and the secretions of typeⅠandⅢcollagen.

OBJECTIVETo compare and evaluate clinical applications of two definitions of metabolic syndrome in children and adolescents, which was developed by Pediatric Academy of Chinese Medical Association in 2012 (Chinese definition) and by International Diabetes Federation in 2007 (IDF definition), respectively.

METHODS593 obese children and adolescents aged 10 ≊16 y from July 2006 to December 2012 were enrolled in the study. The diagnostic concordance of two definitions for metabolic syndrome and individual components was estimated, and their sensitivity and specificity for detecting insulin resistance and early macrovascular complications were compared.

RESULTSThe concordance between two definitions for diagnosing metabolic syndrome was good (kappa=0.626); as for detecting the individual components, the Kappa concordance index were 1.000, 0.803, 0.780, 0.734 and 0.594 for hypertriglyceridemia, hyperglycemia, cholesterol abnormality and hypertension, respectively. The incidence of insulin resistance and early macrovascular complications, detected by the two definitions, were both increased with increasing number of abnormal components. The sensitivity and specificity for detecting insulin resistance in children with metabolic syndrome were 54.5% and 65.7% by Chinese definition, and 36.1% and 83.1% by IDF definition; while the sensitivity and specificity for detecting early macrovascular complications were 58.3% and 55.8% by Chinese definition, and 37.3% and 70.8% by IDF definition. After adjusting for age and sex, compared to the obese children and adolescents without metabolic syndrome, the odds ratios of insulin resistance and early macrovascular complications were 2.166 (P<0.001) and 1.771(P=0.008) for children with metabolic syndrome diagnosed by Chinese definition, and the odds ratio of insulin resistance and early macrovascular complications were 2.618 (P<0.001) and 1.357 (P=0.190) by IDF definition.

CONCLUSIONThe concordance between Chinese and IDF definitions for diagnosing metabolic syndrome in Chinese obese children and adolescents is good. Compared to IDF definition, Chinese definition is more sensitive for hypertension, hyperglycemia and hypercholesterolemia, thus it can more effectively detect insulin resistance and early macrovascular complication.

A model of intrahepatic portal hypertension was established in SD rats by injection of carbon tetrachloride (CCl4). By observing the opening angle of the portal vein, the zero-stress state of the portal veins was studied at different time during the pathogenesis of intrahepatic portal hypertension. After CCl4 injection, the opening angles of the portal veins were increased, in the tenth week, they were much greater than those in the corresponding controls (P<0.05). The results suggest that during the pathogenesis of portal hypertension, unequal remodeling exists in the portal veins to change its biomechanical properties, and the residual stress and strain of the portal veins in portal hypertensive rats are greater than those in normal controls.

Objective To investigate whether FTO gene SNP polymorphisms were associated with metabolic traits in Chinese children. Methods A total of 595 children aged between 6 and 17 years were enrolled. The five common SNPs in the FTO gene(rs1421085,rs17817449,rs8050136,rs3751812 and rs9939609)were genotyped. Metabolic compo-nents and insulin were measured. Results (1)The obese patients showed the components of the metabolic traits were significant difference compared to control group.(2)The allele frequency and the genotype distribution of the five SNPs were significant differences between two groups. Minor allele carriers of the five SNPs were associated with increased risks of childhood obesity compared with the wild-type genotype. (3)After adjustment of age, sex and BMI-z score,all of the five SNPs showed a trend towards higher SBP. In addition, rs3751812 and rs8050136 showed significant as-sociation with LDL-C and HOMA-IR levels. Conclusion The five common SNPs in the FTO gene contributes to the e-tiology of obesity and hypertension. The FTO gene polymorphisms (rs3751812 and rs8050136)are found to be associ-ated with increased insulin resistance and plasma LDL levels.
