ABSTRACT

PURPOSE: To investigate the association between the single nucleotide polymorphisms (SNPs) of the adiponectin gene and nonalcoholic fatty liver disease (NAFLD) as well as the impact of the interaction of multiple SNPs on NAFLD risk, based on a Chinese population study. METHODS: A total of 612 subjects (411 male, 201 female) were selected, including 302 NAFLD patients and 310 controls. Three SNPs were selected for genotyping in the case-control study: rs266729, rs822393, and rs1501299. A logistic regression model was used to examine the interaction between the SNPs and NAFLD. The odds ratio (OR) and 95 % confidence interval (95 % CI) were calculated. Generalized multifactor dimensionality reduction (GMDR) was employed to analyze the interaction among SNPs. RESULTS: Logistic analysis showed a significant association between genotypes of variants in rs266729 and rs822393 and increased NAFLD risk. The carriers of the homozygous mutant of two SNP polymorphisms revealed increased NAFLD risk compared to those with wild-type homozygotes; ORs (95 % CI) were 1.31 (1.14-1.81) (p = 0.001) and 1.18 (1.05-1.71) (p = 0.005), respectively. There was a significant two-locus model (p = 0.0010) involving rs266729 and rs822393, indicating a potential gene-gene interaction between rs266729 and rs822393. Overall, the two-locus models had a cross-validation consistency of 10 and testing accuracy of 62.17 %. Subjects with the CG or GG and CT or TT genotype have the highest NAFLD risk compared to subjects with the CC-CC genotype; the OR (95 % CI) was 2.52 (1.31-3.82), p < 0.001, after covariate adjustment. CONCLUSIONS: Our results support an important association of the rs266729 (-11377 G/C) and rs822393 (-4522 C/T) polymorphism with increased risk of NAFLD. The interaction analysis showed a combined effect of rs266729 and rs822393 on NAFLD.

ABSTRACT

The present study aimed to explore whether the stretch of ischemic myocardium could modulate the electrophysiological characteristics via mechanoelectric feedback (MEF), as well as the effect of phalloidin on the electrophysiological changes. Thirty-two Wistar rats were randomly divided into 4 groups: control group (n=9), phalloidin group (n=7), myocardial infarction (MI) group (n=9), MI + phalloidin group (n=7). The acute myocardial infarction (AMI) was conducted by ligation of the left anterior descending (LAD) coronary artery for 30 min in isolated rat heart. The volume alternation of a water-filled latex balloon in the left ventricle produced the stretch of myocardium. After perfused on Langendorff, the isolated hearts were stretched for 5 s by an inflation of 0.1, 0.2 and 0.3 mL separately and the effect of stretch was observed for 30 s, including the left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), ±dp/dt(max), monophasic action potential duration at 90% repolarization (MAPD90), and occurrence of premature ventricular beats (PVB) and ventricular tachycardia (VT). The stretch caused an increase of MAPD(90) in both control and MI rats (P<0.05, P<0.01). Moreover, MAPD(90) in MI group increased more significantly than that in the control group at the same degree of stretch (P<0.05, P<0.01). Phalloidin (1 μmol/L) had no effect on MAPD(90) in basal state. After stretch, MAPD(90) in phalloidin group slightly increased but was not significantly different from that in the control group. However, phalloidin reduced MAPD(90) in infarcted myocardium, especially when ΔV=0.3 mL (P<0.05). The incidence rates of PVB and VT in MI group were higher than that in the control group (both P<0.01). And there was no significant difference in the incidence rates of PVB and VT between phalloidin group and control group. Phalloidin inhibited the occurrence of PVB and VT in infarcted hearts (both P<0.01). LVSP and +dp/dt(max) in MI group obviously decreased (P<0.01 vs control). With application of phalloidin, LVSP slightly, but not significantly increased in infarcted hearts, while -dp/dt(max) significantly increased (P<0.05). It is suggested that MI facilitates the generation and maintenance of malignant arrhythmias, while phalloidin obviously inhibits the occurrence of arrhythmias.

ABSTRACT

<p><b>OBJECTIVE</b>To study the therapeutic effect of traditional Chinese herbal medicinal preparation Tangshenqing (TSQ) combined with alprostadil in the treatment of early- and intermediate-stage diabetic nephropathy (DN).</p><p><b>METHODS</b>One hundred and twenty DN patients were randomized into 3 groups for different treatment protocols. The patients in the control group were given the basic treatment (low-protein diabetic diet and rigorous control of blood glucose, blood pressure, and blood fatty acid), and those in treatment group A received TSQ (containing Astragalus membranaceus, Panax notoginseng, Epimedium brevicornum, etc) in addition to the basic treatment, and those in treatment group B were treated with alprostadil injections (for 14 consecutive days) in addition to the treatment given in group A. Therapeutic effect evaluation was carried out after a 30-day treatment in all the patients.</p><p><b>RESULTS</b>The overall efficaey rate of the treatment was 78.37% in the control group, 88.57% in the treatment group A, and 94.44% in treatment group B, suggesting better therapeutic effect in the latter two groups than in the control group (P<0.05). Patients in all the 3 groups exhibited symptomatic improvement of various degrees, but the treatment group B had the best results. After the treatments, the patients' blood glucose and fatty acids were lowered, without obvious difference between the 3 groups. Compared with the control group, the patients in the two treatment groups showed significant reduction in fibrinogen, 24-h urine microprotein and urine protein after the treatment (P<0.01 or 0.05).</p><p><b>CONCLUSION</b>Combined use of traditional Chinese herbal medicine TSQ and alprostadil injections produces definite therapeutic effect on early- to intermediate-stage DN.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of integrative Chinese and Western medicine (ICWM) on improvement of the islet beta cell function in treating patients with latent autoimmune diabetes mellitus in adults (LADA).</p><p><b>METHODS</b>Eighty-four patients of LADA were randomly divided into 3 groups (20 in A, 33 in B and 31 in C), they were treated respectively with sulfonylurea, insulin and combination of insulin and Chinese medicine. The changes before and after treatment in blood glucose, glycohemoglobin and islet beta cell function were observed.</p><p><b>RESULTS</b>After treatment, the damaged islet beta cell function in Group A was not improved, the secrete peak value of C-peptide was still low and delayed in Group A, but in Group B and C, it shifted earlier, suggesting that a certain degree of improvement and recovery of islet beta cell function. The improving effect in Group C was better.</p><p><b>CONCLUSION</b>Chinese herbal medicine had effect in lowering blood glucose and improving islet beta cell function in patients with diabetes mellitus, and showed a synergistic and enhancing action when combined use with insulin. Early treatment of insulin or combination of insulin and Chinese medicine should be applied to patients with LADA.</p>
