Clinical significance of HIF-1 alpha, MMP-2, and e-cadherin expression in rectal carcinoma

To investigate the clinical significance of aberrant hypoxia inducible factor-la [HIF-la], matrix metalloproteinase-2 [MMP-2], and E-cadherin expression in rectal adenocarcinoma. Prospective study.Chongqing Medical University, Chinese Ministry of Education Key Laboratory of Child Development and Disorders, Chongqing Provincial Key Laboratory of Pediatrics, Chongqing, China A total of 88 rectal adenocarcinoma tissues and 12 normal mucosa specimens were included in the study. The expression of HIF-la, MMP-2 and E-cadherin protein were detected by using immunohistochemistry. Clinico-pathological factors associated with expression of HIF-la, MMP-2, and E-cadherin were analyzed using the x[2] test. Survival curves were plotted according to the Kaplan-Meier method. HIF-la, MMP-2, and E-cadherin protein expression Results: HIF-la, MMP-2, and E-cadherin proteins were expressed in 65.9%, 71.6%, and 28.4% of rectal cancer tissues, respectively. However, HIF-la and MMP-2 proteins were not expressed, but E-cadherin protein was strongly expressed in 12 normal tissue samples. Altered HIF-la and MMP-2 protein expression was associated with lymph node and distant metastases and Duke's classification, while loss of E-cadherin protein expression was associated with tumor de-differentiation and lymph node and distant metastases. Combining these three markers together, the association was even more significant. Kaplan-Meier curve analysis showed that HIF-la and MMP-2 protein expression but loss of E-cadherin protein expression significantly contributed to poor overall patient survival. Altered HIF-la, MMP-2, and E-cadherin protein expression significantly contributed to the progression of rectal carcinoma and poorer patient survival

Effects of nutritional management intervention on gestational weight gain and perinatal outcome

To evaluate whether nutritional management intervention can prevent excessive weight gain during pregnancy and improve perinatal outcomes. This cross-sectional study included 276 pregnant women undergoing prenatal care between June 2010 and December 2011 at the Obstetrics and Gynecology Department of the Second Affiliate Hospital of the ChongQing University of Medical Sciences, Chongqing, China. Of them, 131 women received individualized nutritional management in addition to routine prenatal care [intervention group], and 145 women received only routine prenatal care [control group]. The primary study outcome was gestational weight gain [GWG]. Secondary outcomes included birth weight, Apgar score, and incidence of pregnancy complications. Baseline demographic characteristics of the 2 groups were the same. The average GWG was higher in the control group [12.57 +/- 4.62 kg] compared with the intervention group [7.58 +/- 1.59 kg; p=0.000]. The incidence rate of preeclampsia was 3.1% and gestational diabetes was 3.8% for the intervention group, compared with 11% for preeclampsia and 14.5% gestational diabetes for the control group [p<0.05]. The incidence rates of premature rupture of membranes, preterm labor, birth weight, birth of a newborn, and major congenital anomalies did not significantly differ between the 2 groups. Nutritional management intervention prevented excessive GWG and improved perinatal outcomes. These results support the hypothesis that nutritional management intervention can decrease the rate of complications experienced by expecting mothers

Age-dependent alternations in beta-adrenoceptor function in human detrusor and possible mechanism / 中华外科杂志

<p><b>OBJECTIVE</b>To study the age-dependent alternations in beta-adrenergic response and possible mechanism.</p><p><b>METHODS</b>The response to beta-adrenergic agonists isoprenaline and BRL37344, forskolin and dibutyryl cyclic AMP (DBcAMP) of samples from senile people in 10 cases were examined by cellular functional test. Radioligand binding assay was also performed using non-selective beta-adrenergic receptors ligand [(3)H]-dihydroalprenolol ([(3)H]-DHA), the specimens of young men in 10 cases as the control group.</p><p><b>RESULTS</b>There was no age-dependent change in the contractile response to potassium chloride. The relaxing responses to isoprenaline, BRL37344 and forskolin decreased by 15.0%, 17.6% and 12.6% respectively (P < 0.01). The pD(2) values of the isoprenaline and BRL37344 also declined significantly. There was no difference in the responses to DBcAMP between the two groups. The maximum binding site decreased significantly with increasing age, but the equilibrium-dissociation constant did not change.</p><p><b>CONCLUSIONS</b>There is an age-related decline in beta-adrenergic responsiveness, which might be one of the causative factors of the reduced bladder compliance of the elderly. The decrease of cAMP level caused by the reduced receptor density and adenyl cyclase activity might be the molecular mechanisms underlying the changes of beta-adrenergic responsiveness.</p>
