Objective To evaluate the relationship between the carotid atheroscalerosis and coronary artery disease. Methods High frequency ultrasonography was used to examine the carotid artery in seventy two patients who had undergone coronary artery angiography because of acute myocardiac infarction, angina or chest pain. They were divided a group with normal coronary angiography and another group with coronary artery lesion. The latter group included three subgroups according to the number of coronary artery involved: B1 group, B2 group, and B3 group. Scoring of atherosclerosis of the common carotid artery, internal carotid artery and external carotid artery were made with reference to plaques, the intima media thickness (IMT) and the V max of blood flow of the carotid artery as demonstrated by high frequency ultrasonograply. Results The IMT of the group with coronary lesion was significantly higher than that of the normal group ( P

Objectives To explore the relevant factors of liver X receptor (LXR) and lipid metabolism in school-age chil-dren with obesity. Methods A total of 80 obese children were selected by indexes of physical growth from pupils in Grades 1-6, aged 7-14 years from June 2011 to October 2011. Fifty-one age and sex matched children with normal BMI were chosen as nor-mal controls. The metabolic indexes including aspartate transaminase (AST), alanine aminotransferase (ALT), glutamyl transpep-tidase (GGT), total cholesterol (CHOL), triacylglycerol (TG), high density lipoprotein cholesterol (HDL-C), low density lipopro-tein cholesterol (LDL-C) and expression of LXR were detected in fasting blood. Results The expression level of LXR in obese children (9.14 ± 1.15) was higher than that in control children (2.84 ± 3.68) with significant difference (t=4.55,P=0.000). Eighty percent (80%) of obese children were LXR>1 (64/80) which was higher than that of control children (23/51, 45.1%), and signifi-cant difference was found between the two groups (χ2=17.01, P=0.000). Compared to controls, the levels of AST, ALT, GGT, CHOL, TG and LDL-C were higher while the level of HDL-C was lower in obese children (P<0.05). The correlation analysis found that AST, ALT, CHOL, LDL-C and BMI were positively correlated with LXR (r=0.18~0.26,P<0.05). Logistic regression ana-lysis showed that AST≥40IU/L (OR=1.076), ALT≥40IU/L (OR=1.036), CHOL≥5.20 mmol/L (OR=2.038), LDL-C≥3.36 mmol/L (OR=2.176) and BMI≥18.9 kg/m2 (OR=1.131) were risk factors for LXR>1 (P<0.05). Conclusions Obesity in school-age chil-dren can up-regulate the expression of liver X receptor and cause liver damage and abnormal lipids metabolism.

Objective To investigate the clinical features of patients with multiple sclerosis (MS) and restless legs syndrome (RLS) and to further examine relevant factors that may contribute to the co-occurrence of MS and RLS.Methods Seventy MS patients were recruited in the present study.The RLS screen was further performed in MS patients based on the diagnostic criteria for RLS.MS patients with RLS were designated as the case group and MS patients without RLS served as the control group.The clinical data including age of MS onset,MS duration and clinical disability by the expanded disability status scale (EDSS) were analyzed.Results There were 12 MS patients with RLS in total 70 MS patients and the incidence rate was 17.1％.The average age of MS onset in the RLS group was (47.6 ± 10.0) years,and (40.1 ± 10.4 ) years in the control group.The difference of average age of MS onset was found to be significant (t =2.29,P =0.030).The average history of MS in the RLS group was ( 12.6 ± 6.8 ) years,and ( 8.2 ± 6.6) years in the control group ( t =2.10,P =0.039).The average EDSS of the RLS group was 4.5 ±2.5,and 2.5 ±2.0 in the control group (t =3.02,P =0.004).There was no significant association between RLSRS and EDSS in MS patients with RLS (P =0.15).Conclusion The incidence rate of RLS in MS patients was high.Among patients with MS,RLS was associated with older age,longer MS duration,and more severe disability.

Objective To evaluate the efifcacy and safety of Xiyanping in the treatment of hand-foot and mouth disease. Methods Based on the principles and methods of Cochrane systematic reviews, Cochrane Library, PubMed, Medline, Chinese Bio-medicine Database (CBM), China Journal Full-text Database (CNKI), VIP database and Wanfang database were searched. All of the randomized controlled trials (RCT) of Xiyanping versus ribavirin were included. The data were extracted and evalu-ated by two reviewers independently. Risk assessment tool was used to assess the risk of bias and software Revman5.0 was used for meta-analysis. Results Twenty-four RCT and 3314 patients were included. Comparing to ribavirin, Xiyanping showed better therapeutic outcomes regarding to total effective rate, durations of fever and rash elimination (RR=1.17, 95%CI:1.12~1.23;MD=-1.56, 95%CI:-2.10~-1.02;MD=-1.41, 95%CI:-1.90~-0.93). Side effects were rare in both groups and could be recovered after drug withdrawal. Conclusions The current evidence suggests that Xiyanping is superior to ribavirin in the treatment of hand-foot and mouth disease.

Objective To observe the expression of insulin receptor mRNA in skeletal muscle and the change of oxidative stress in diabetic rats at different intensity training.Methods Sprague-Dawley rats were divided into group A(control group),group B(non-exercise group),group C(low-intensity exercise group),group D(moderate-intensity exercise group) and group E(high-intensity exercise group),6 rats in each group.A diabetic rat model was induced by injecting streptozotocin(STZ)for 4 weeks after high lipid and glucose breeding.Rats were trained for 6 weeks on a treadmill.Serum glucose and insulin,insulin resistance index(HOMA-IR),activities of SOD and GSH-Px,and MDA were detected before and after training.Expression levels of InsR mRNA in skeletal muscle were measured by RT-PCR.Results The InsR receptor mRNA expression level in three exercise groups at different intensities was 0.55?0.05,0.53?0.04,and 0.41?0.05,respectively,and was significantly higher in low and moderate intensity exercise groups than in group B (P

The efficacy and safety of uric-acid-lowering therapy (UALT) on slowing the progression of chronic kidney disease (CKD) accompanied by hyperuricemia were assessed. We searched Cochrane Library, PubMed, EMbase, CNKI, Wanfang and Vip databases up to November 15, 2012 for randomized controlled trials (RCTs) which compared the effect of UALT to control therapy in hyperuricemic patients secondary to CKD, and then performed quality evaluation and meta-analysis on the included studies. Seven RCTs involving 451 cases were included. UALT delayed the increase of serum creatinine (MD=-62.55 μmol/L, 95% CI: -98.10 to -26.99) and blood urea nitrogen (MD= -6.15 mmol/L, 95% CI: -8.17 to -4.13) as well as the decrease of glomerular filtration rate [MD=5.65 mL/(min·1.73 m2), 95% CI: 1.88 to 9.41], decreased systolic blood pressure (SBP) (MD= -6.08 mmHg, 95% CI: -11.67 to -0.49), and reduced the risk of the renal disease progression (RR=0.30, 95% CI: 0.19 to 0.46). However, there was no statistically significant difference in 24-h urinary protein quantity and diastolic blood pressure (P>0.05). We identified that UALT could delay the progression of CKD with secondary hyperuricemia. And this also indirectly proved that hyperuricemia was a risk factor for the CKD progression.

Objectives To investigate the serum uric acid level and its related factors in obese children. Methods Obese children were selected from all pupils (ages 7-14) of 3 primary schools. Age-and sex-matched children with normal body mass index (BMI) were chosen as normal controls. Fasting venous blood samples were collected to detect uric acid (UA), glucose (GLU), total cholesterol (CHOL), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipopro-tein cholesterol (LDL-C). Results Sixty-eight (2.2%) obese children (57 boys and 11 girls) were detected from 3 000 children. Compared with 136 normal controls, the blood pressure (BP), levels of UA, CHOL, TG and LDL-C, and waist circumference (WC) were higher while HDL-C was lower in obese children (P<0.05). The detection rate of hyperuricemia in obese children (35.3%) were signiifcantly higher than that in normal controls (5.9%) (P<0.05). UA was positively related with WC, BMI, BP and TG, negatively related with HDL-C. Conclusions Obesity can lead to higher serum UA, higher BP and abnormal lipid metabolism. The level of serum UA was correlated with BP and abnormal lipid metabolism.

Objective To compare genomic expression differences between androgenic complete hydatidiform mole (AnCHM) and normal first trimester villi with similar gestation weeks,and search for potential adjuvant diagnostic molecular markers.Methods Short tandem repeat (STR) detection was used to identify AnCHM,human oligonucleotide array U133 Plus 2.0 was used to measure genomic expression differences between AnCHM and normal villi,and quantitative fluorescent RT-PCR was used to verify array of several genes.Results Nine of 11 histologically diagnosed complete hydatidiform moles were found to be AnCHM by means of STR,and the other 2 were biparental complete hydatidifonn mole (BiCHM). Compared with villi,oligonueleotide array showed 279 genes (0.72%,279/38 500) were over expressed and 1710 genes (4.44%,1710/38 500) under expressed in AnCHM.Bioinformatics analysis found that differentially expressed genes were involved in multiple biological processes and pathways.Changes of imprinting genes,growth hormone genes and chorionie somatomammotropin hormone genes were especially remarkable.Conclusions Pathogenesis of AnCHM is a complex process involving multiple genes and pathways.Altered expression of imprint genes may play important roles in the process.
