OBJECTIVEThis study aims to determine the gene expression changes of iron transporters-divalent metal transporter 1 (DMT1) and ferroportin 1 (Fpn1) in the duodenal tissue of diet-induced obese mice.

METHODSC57BL/6J mice were randomly divided into normal control (NC) and obesity model (OM) group, 6 in each, and fed on conventional and high-fat diet respectively for 14 weeks by table of random number. Then the DMT1 and Fpn1 mRNA contents in duodenal tissues of the animals were measured by Real-time PCR method, and the protein expression levels were analyzed by Western blot test.

RESULTSThe Real-time PCR detection results showed that, compared with the NC group for which the mRNA expression level was defined as 1.0, the Fpn1 mRNA expression in OM group (0.58±0.11) was reduced significantly (t = 6.71, P = 0.014), whereas the relative expression level of DMT1 mRNA in OM group (0.89±0.26) showed no obvious alteration (t = 2.01, P = 0.122). Western blot results showed that the relative protein expression levels of Fpn1 in OM and NC group were 0.32±0.06 and 0.65±0.19, respectively, and the difference was statistically significant (t = 5.37, P = 0.026). The DMT1 protein relative abundance was 0.88±0.21 in OM group and 0.92±0.17 in NC group, and the difference has no statistical significance (t = 1.84, P = 0.185).

CONCLUSIONFpn1 gene expression is inhibited in the duodenum of diet-induced obesity mouse while DMT1 expression keeps unchanged, and this implies that decreased iron export from enterocytes into circulation might be responsible for the impaired iron absorption in obesity.

BACKGROUND:Pathophysiological mechanisms after spinal cord injury are very complex, so there is no compressive and in-depth understanding on it.
OBJECTIVE:To study the effect of dura mater spinalis integrity on cytokine levels in the cerebrospinal fluid of animal models of spinal cord injury.
METHODS:The white rabbit models of spinal cord injury were established using clamp compression method, and then the models were randomly divided into four groups:no dura mater spinalis defect group, dura mater spinalis defect group, dura mater spinalis defect composite with membrane repairing group and dura mater spinalis defect composite with autologous fascia repair group. Enzyme-linked immunosorbent assay was
performed to detect the changes of levels of cytokines (interleukin-6, interleukin-10 and tumor necrosis factorα) in the cerebrospinal fluid at 30 minutes, 1, 3, 6, 12 and 36 hours after surgery.
RESULTS AND CONCLUSION:The levels of interleukin-6, interleukin-10 and tumor necrosis factorαin the
cerebrospinal fluid of the dura mater spinalis defect group, dura mater spinalis defect composite with membrane repairing group and dura mater spinalis defect composite with autologous fascia repair group were significantly lower than those of the no dura mater spinalis defect group at 6 hours after surgery (P<0.05). There were no significant differences in the levels of interleukin-6, interleukin-10 and tumor necrosis factorαat other time points between groups (P>0.05). The results indicate that maintaining the integrity of dura mater spinalis of the spinal cord injury model can affect the levels of interleukin-6, interleukin-10 and tumor necrosis factorαin the
cerebrospinal fluid, thus inhibiting the inflammatory response.

OBJECTIVETo investigate the prevalence and risk factors of hyperuricemia in the subjects undergoing routine physical examinations in Guangzhou.

METHODSThis study was conducted among 8302 subjects (5136 male and 3166 female) undergoing routine physical examinations in a hospital in Guangzhou during the period from October 1, 2010 and December 31, 2011. For all the subjects, such indices as body height, weight, waist circumference, hip circumference, blood pressure, heart rate, and blood biochemistry were examined, and the body mass index (BMI) and waist-hip ratio were calculated. The risk factors of hyperuricemia were analyzed using univariate and multivariate logistic regression analysis.

RESULTSHyperuricemia was detected in 35.68% of the total subjects, and the detection rates were significantly higher in male than in female subjects (46.83% vs 17.59%, P<0.0001). Unconditional logistic regression analysis showed a significant correlation of hyperuricemia with age, sex, BMI, hypertension, waist-hip ratio, triglycerides, low-density lipoprotein (LDL), very low-density lipoprotein cholesterol (VLDL-C), creatinine, and blood urea nitrogen (P<0.05). Multivariate logistic regression analysis identified BMI, blood pressure, waist-hip ratio, hypertriglyceridemia, LDL, VLDL-C, creatinine, and urea nitrogen as the risk factors for hyperuricemia, and age and gender were negatively correlated with the incidence of hyperuricemia with OR values of 0.991 and 0.660, respectively.

CONCLUSIONHyperuricemia has a high prevalence in the subjects undergoing routine physical examinations in Guangzhou. The risk factors of hyperuricemia include hypertension, hypertriglyceridemia, and elevations of BMI, waist-hip ratio, LDL, VLDL-C, creatinine, and blood urea nitrogen. Age and gender can be protective factors against hyperuricemia.
