Background Exfoliation syndrome (XFS) is a systemic disease with abnormal accumulation of extracellular matrix.Researches showed that the single nucleotide polymorphisms (SNPs) of lysyl oxidase-like 1 (LOXL1) gene is associated with the pathogenesis of XFS in global population.However,the results are varied among different ethnicity and regions.Objective This study aimed to assess the association between LOXL1 gene polymorphisms and XFS in Uygur population.Methods One-hundred and fifty-two Uygur XFS patients without relativeness were enrolled from January to August in 2014,and 228 ethnicity-and gender-matched normal controls were recruited at the same period from the same region.Each individual underwent comprehensive eye examinations and 5 ml peripheral blood was collected.Genomic DNA was extracted from peripheral blood.PCR-ligase detection response (LDR) was used to determine the allele and genotype frequencies of the six SNPs rs12914489,rs4886467,rs4558370,rs4461027,rs4886761 and rs16958477 in the promoter region of LOXL1 gene.The distribution frequency between the patients and normal controls was compared by x2 test.Logistic regression analysis was used for age adjustment.This study was approved by Ethic Committe of Xinjiang Medical University,and informed consent was obtained from the subjects.Results rs12914489 site in the normal control group diverged from Hardy-Weinberg equilibrium (HWE) (P =0.033),and the rs4886467,rs4558370,rs4461027,rs4886761 and rs16958477 sites followed HWE.The frequencies of G allele and GG genotype of rs4886467 in the XFS group were lower than those in the control group (both at P =0.00) and were protective factors of XFS (OR =0.54,95 ％ CI:0.40-0.74,P =0.000;OR=0.51,95％ CI:0.33-0.78,P=0.001);the frequencies of T allele and TT genotype of rs4558370 in the XFS group were significantly higher than those in the control group (both at P=0.00) and were the risk factors of XFS (OR=1.96,95％ CI:1.23-3.11,P =0.004;OR =2.18,95％ CI:1.31-3.64,P =0.002);the frequencies of C allele and CC genotype of rs4461027 in the XFS group were significantly higher than those in the control group (both at P=0.00) and were the risk factors of XFS (OR=2.25,95％ CI:1.67-3.04,P=0.000;OR=3.06,95％ CI:1.89-4.96,P=0.000);the frequencies of T allele and TT genotype of rs4886761 in the XFS group were significantly higher than those in the control group (both at P=0.00) and were the risk factors of XFS (OR=2.44,95％ CI:1.79-3.33,P =0.000;OR =3.02,95％ CI:1.63-5.60,P =0.000);the frequencies of C allele and CC genotype of rs16958477 in the XFS group were significantly higher than those in the control group (both at P=0.00) and were the risk factors of XFS (OR =2.00,95 ％ CI:1.47-2.71,P =0.000;OR =2.37,95 ％ CI:1.31-4.27,P =0.004).Conclusions The SNPs of promoter region of LOXL1 gene are associated with hereditary susceptibility of XFS individually in Uygur population.The SNPs of rs4886467 locus are protective factor,while the SNPs of rs4558370,rs4461027,rs4886761 and rs16958477 locus are risk factors for pathogenesis of XFS.

Objective To investigate the relationship between isolated systolic high-normal blood pressure and cor-onary heart disease (CHD) in the middle-aged and elderly population. Methods A total of 236 patients over 50 years old and undergone coronary angiography were enrolled and divided into isolated systolic high-normal blood pressure (ISHNBP) group (n=135) and non-ISHNBP (NISHNBP) group (n=101) according to their systolic and diastolic blood pressure levels. All clinical data and angiographic data were collected. Results There was no significant difference in systolic blood pres-sure between NISHNBP group and ISHNBP group (P>0.05). There were significantly lower levels of diastolic blood pres-sure and higher pulse pressure in ISHNBP group (P＜0.01). Results of multivariate logistic analysis showed that isolated sys-tolic high-normal blood pressure was the independent risk factor for CHD (OR=2.67,95%CI:1.50-4.75, P＜0.01). And the distribution of diseased coronary vessel numbers was more extensive in the ISHNBP group (P＜0.01). Conclusion The iso-lated systolic blood pressure in the middle-aged and elderly population with high risk of coronary heart disease should be paid attention to, and make appropriate interventions, which may help reduce the incidence of cardiovascular disease.

Objective To assess the effects of management by diabetes specialist nurse (DSN) on blood glucose control.Methods A comprehensive search of databases was carried out including PubMed,the Cochrane Library,Web of Science,China National Knowledge Infrastructure (CNKI),Chinese Biomedical Literature Database (CBM),China Scientific Journal Database (VIP) and Wanfang Database from their inception to November 2013 in any language to identify trials.Searching of relevant publications was undertaken to identify additional trials.Randomized controlled trials and quasi-randomized controlled trials dealing with the effects of management by DSN on glycosylated hemoglobin (HbA lc) were included in the review.Two investigators performed data extraction and quality assessment independently.Statistic analysis were carried out using RevMan5.2 software.Results Eighteen trials were included finally.Meta-analysis showed that management by DSN can better control the blood glucose of patients(WMD=-0.63,95％CI-0.88--0.38),but the effect was influenced by intervention time,location and type of the diabetes mellitus.Conclusions The presence of a DSN can improve patients' blood glucose control,especially in the long-term control of blood glucose.

Objective To investigate the correlation of diastolic blood pressure (DBP) ＜70mm Hg and isolated systolic hypertension (ISH) with coronary atherosclerosis (CAS) and coronary heart disease (CHD) in elderly patients and to analyze the independent risk factors for low DBP.Methods A total of 246 elderly patients with untreated ISH who underwent coronary angiography were divided into the low DBP group (n=102) and the non-low DBP group (n=144) according to DBP level.All clinical and angiographic data were collected and the retrospective analysis was performed to assess the risk of CAS and CHD in patients with low DBP and to analyze the risk factors for low DBP.Results There were no significant differences in systolic pressure level between the low DBP group and the non low DBP group [(156.2±15.6) mmHgvs.(154.4±14.2) mmHg,t=0.93,P＞0.05],while pulse pressure level was significantly higher in the low DBP group than in the non-lowDBPgroup [(91.3±±17.7) mmHgvs.(72.9±15.1) mm Hg,t=8.54,P＜0.01].Stepwise logistic analysis showed that age,diabetes and smoking were independent risk factors for low DBP.After adjustment for age,gender and other common risk factors,low DBP was independently associated with CAS and CHD (OR =1.72 and 1.44,95％ CI:1.082.72 and 1.04-1.99,respectively,both P＜ 0.05).Conclusions Low DBP is independently associated with CAS and CHD in elderly patients with untreated ISH.Age,diabetes and smoking are the independent risk factors for low DBP.

OBJECTIVE: To determine the levels of visfatin in patients with chronic kidney disease (CKD) and to explore the relationship between visfatin levels and caroid atherosclerosis in CKD patients. METHODS: A total of 180 CKD patients (102 non-dialyzed patients and 78 dialysis patients) and 42 healthy subjects enrolled in this study. The serum levels of visfatin, IL-6, and high sensitive C-reactive protein (hsCRP) were measured by ELISA. Common carotid arteries intima-media thickness (CCA-IMT), cross-sectional calculated intima-media thickness (c IMT) area and atherosclerotic plaque were detected by non-invasive high-resolution B-mode ultrasonography. RESULTS: The serum levels of visfatin, IL-6 and hsCRP were significantly increased in CKD patients compared with age matched healthy subjects (P<0.01). The serum levels of visfatin, IL-6 and hsCRP in the dialyzed patients were significantly higher than those in non-dialyzed patients (P<0.05). Visfatin levels increased with the progression of renal dysfunction and inversely related to creatinine clearance (Ccr) in non-dialyzed patients (r=-0.415, P<0.05). Patients with carotid artery plaques showed significantly higher levels of visfatin[(34.22±7.96) ng/mL)] compared with those without plaques [(28.24±6.18) ng/mL, P<0.05]. The serum levels of visfatin were closely correlated with IL-6 (r=0.548, P<0.001), hsCRP (r=0.430, P<0.001), CCA-IMT (r=0.462, P<0.05), and c IMT area (r=0.411, P<0.05). After adjusting for GFR, age, gender, and other risk factors associated with atherosclerosis, multiple stepwise regression analysis showed that serum visfatin is a independent risk factor for CCA-IMT (β=0.433, P<0.01) and c IMT area (β=0.412, P<0.01). CONCLUSION The serum level of visfatin increase with the progression of CKD and should be considered to be a new risk factor for atherosclerosis in CKD.

BACKGROUND: Hippocampal neuron presents remarkably injury in cerebral after seizure of epilepsy. Necrosis and apoptosis are two kinds of neural cell injury after epilepsy and play an important role in neural injury of epilepsy. Being endogenous neural protective transmitter, adenosine may inhibit the release of excitatory amino acid, production of oxygenic free radical and action of nitric oxide. Simultaneously, it can improve cerebral blood flow and anti-convulsion. But it has been unknown concerning to the relationship between adenosine and cell apoptosis after epilepsy yet.OBJECTIVE: To observe the effects of 2-CAdo adenosine-receptor excitant on genetic expression of bcl-2, Bax of hippocampal cells in epileptic rats and further probe into the mechanism of adenosine on anti-convulsion and brain protection.DESIGN: Completely randomized controlled experimental research in which the experimental animals were taken as the objects.SETTING: Pediatrics department and general surgical department of one oil field general hospital, and pediatric internal department of a hospital affiliated to one university.MATERIALS: The experiment was performed in Experimental Zoology Departnent and Pathological Teaching & Research Department of Harbin Medical University from October 2002 to March 2003. Totally 104 Wistar rats of either sex were employed, weighing varied from 200 g to 250 g. The animals were randomly divided, named as normal group 8 rats, epileptic group 32 rats, epileptic & 2-CAdo group 32 rats, and epileptic & physiological saline group 32 rats.INTERVENTIONS: The animal epileptic model was set up by intra-abdominal injection of coriamyrtin 15 mg/kg(provided by Pathology Department of Harbin Medical University. Convulsion presented in all of rats, 5 minutes later after injection, lasting for 1 or 2 minutes. In epileptic & 2-CAdo group, 2-CAdo(provided by ICN company), 0.6 mg/kg, was injected from the vein on the tail 1 hour before coriamyrtin injection and 1 hour after convulsion respectively. In epileptic & physiological saline group, the physiological saline of equal dosage was injected from the vein on the tail 1 hour before coriamyrtin injection and 1 hour after convulsion respectively.MAIN OUTCOME MEASURES: Positive cell counts of bcl-2 and Bax genetic expression in hippocampal CA1 area.RESULTS: Twenty-four hours after epilepsy seizure, neural cell bcl-2 expression was increased in hippocampal CA1 area, was remarkably decreased in 48 hours, and the expression was only little amount in 72 hours, but it was increased again in 7 days. Bax expression began increased in 24 hours after epilepsy seizure, was significantly increased in 48 hours, reached the peak in 72 hours, the expression was the minimum in 7 days. In epileptic & 2-CAdo group, bcl-2 expressions at corresponding times were remarkably increased compared with epileptic group and epileptic & physiological saline group( P＜ 0.05), Bax expressions were remarkably decreased compared with epileptic group and epileptic & physiological saline group( P ＜ 0.05), indicating statistical significance.CONCLUSION: 2-CAdo can reduce apoptosis of hippoeampal neural cells after epilepsy seizure and provide a certain protection for neural cells.

Objective To investigate the changes in myocardial proteomics in the late phase of limb ischemic preconditioning (LIP) in rats.Methods Twelve pathogen-free adult male Sprague-Dawley rats,aged 8-9 weeks,weighing 260-280 g,were randomly assigned into LIP group (n=6) and control group (group C,n=6) using a random number table.Limb ischemia was preceded by 3 cycles of 5-min ischemia which was induced by ligation of the root of the right hindlimb with a rubber band followed by 5-min reperfusion in group LIP.At 24 h after LIP,the tissues were obtained from the left ventricle,and the isobaric tags for relative and absolute quantification technique and liquid chromatography-mass spectrometry were applied to detect the differences in protein expression profiles between the two groups (the difference in expression between the two groups＞ 1.2 times and P＜0.05).The identified differentially expressed proteins were analyzed using the bioinformatics,and some were further verified by Western blot.Results A total of 55 proteins were identified to be differentially expressed,and among the 55 proteins,the expression of 35 proteins was up-regulated,and the expression of 20 proteins was down-regulated.Bioinformatics analysis showed that most of the 55 proteins were organelles,cell membrane or macromolecular compounds,were involved in the process such as metabolism,biological regulation,stress response and signal transduction,and showed functions such as the binding affinity to molecules,catalytic activity,anti-oxidant activity,and modulation of the activity of enzyme.The results verified by Western blot were consistent with those shown by using the isobaric tags for relative and absolute quantification analysis.Conclusion The late phase of LIP can induce changes in the expression of the 55 proteins involving regulation of energy metabolism,anti-oxidant action,regulation of gene expression,and protein folding and degradation in the myocardium,which may be the mechanism of myocardial protection in rats.
