Abstract
BACKGROUND Recently, widespread interest has grown regarding melatonin treatment of hypertension including its cardioprotective effects. Studies in rodents indicate that melatonin plays a role in the pathogenesis of hypertension in rats with metabolic syndrome. Piromelatine, a melatonin agonist, serotonin 5-HT-1A and 5-HT-1D agonist and serotonin 5-HT2B antagonist is a multimodal agent with sleep promoting, anti-diabetic, analgesic, anti-neurodegenerative, anxiolytic and antidepressant potential, currently in development for the treatment of insomnia. AIM In this report we assessed the effects of piromelatine and melatonin treatment on blood pressure in spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto (WKY) rats. MATERIALS AND METHODS Five groups of 12-wk-old rats (10/group) were treated for 5 weeks with a vehicle, piromelatine (5, 15 and 50 mg/kg BW) and melatonin (10 mg/kg BW) and an age-matched WKY control group. Systolic blood pressure (tail-cuff method) was measured weekly at 9:00 a.m. and at 9:00 p.m. The rats body weight, plasma glucose, insulin, triglyceride, adiponectin, total cholesterol, HDL and LDL/VLDL cholesterol were also measured. RESULTS Our results showed that both piromelatine and melatonin reduced SHR blood pressure significantly both during the morning and the evening. Piromelatine, but not melatonin, also reduced SHR body weight gain and both significantly decreased plasma glucose and insulin levels and increased adiponectin levels. CONCLUSIONS Piromelatine, similar to melatonin, has an antihypertensive effect and also attenuates body weight, improves metabolic profiles and might be useful in the treatment of hypertension and the metabolic syndrome.

Abstract
OBJECTIVE The purpose of this study was to assess the ability of a new dentifrice containing arginine, an insoluble calcium compound, and fluoride to arrest or reverse naturally occurring buccal caries lesions measured using Quantitative Light-induced Fluorescence (QLF). METHODS Three study groups used dentifrices which contained 1) 1.5% arginine and 1450 ppm fluoride as sodium monofluorophosphate (experimental), 2) 1450 ppm fluoride as sodium monofluorophosphate (positive control), and 3) no fluoride (negative control). All three dentifrices were formulated in the same calcium base. The study participants were from three schools in the city of Chengdu, Sichuan Province, China. A total of 446 of 450 recruited subjects completed the study. Of these, 147 were in the experimental, 148 in the positive control, and 151 in the negative control groups. The initial age of the children was 10-12 years (mean 11.4 +/- 0.54); 47.5% were female. RESULTS Using QLF, assessments of buccal caries lesions were made at baseline and after three and six months of product use. For AQ, representing lesion volume, the baseline mean value for the three groups was 27.30, and at the three-month examination the mean values were 16.76, 19.25, and 25.89 for the experimental, positive, and negative control dentifrices, respectively. This represents improvements from baseline of 38.6%, 29.5%, and 5.2%. At six months, the deltaQ values for the three groups were 13.46, 18.47, and 24.18, representing improvements from baseline of 50.7%, 32.3%, and 11.4%. For all QLF metrics, deltaF (loss of fluorescence), area, and deltaQ, the differences between the negative control and both the experimental and positive control groups were statistically significant (p < or = 0.01). The differences between the experimental and positive control groups attained statistical significance for deltaQ (p < or = 0.003) at the six-month examination. CONCLUSION It is concluded that both of the fluoride-containing toothpastes are significantly better at arresting and reversing buccal caries lesions than the non-fluoride toothpaste. Furthermore, it is concluded that the new dentifrice containing arginine, an insoluble calcium compound, and fluoride provides significantly greater anticaries benefit than a dentifrice containing fluoride alone.

Abstract
OBJECTIVE The purpose of this six-month study was to assess the ability of a new dentifrice containing 1.5% arginine, an insoluble calcium compound, and 1450 ppm fluoride, as sodium monofluorophosphate, to arrest and reverse primary root caries lesions in adults. METHODS Three test groups used dentifrices which contained either: 1) 1.5% arginine and 1450 ppm fluoride as sodium monofluorophosphate in a calcium base (experimental); 2) 1450 ppm fluoride as sodium fluoride in a silica base (positive control); or 3) no fluoride in a calcium base (negative control). The study participants were residents of the city of Chengdu, Sichuan Province, China. In order to take part, subjects had to have at least one non-cavitated primary root caries lesion. A total of 412 subjects completed the study. They were aged from 50 to 70 years (mean age 64 +/- 4.1 years) and 53.6% were female. Efficacy for arresting and reversal of primary root caries was assessed by clinical hardness measures and through the use of the Electrical Caries Monitor. RESULTS After three months of product use, clinical hardness measures showed that 27.7%, 24.6%, and 13.1% of lesions had improved in the experimental, positive, and negative control groups, respectively, and 0.7%, 4.5%, and 16.8% had become worse, respectively. The differences in the distribution of lesion change between the negative control group and both the experimental (p < 0.001) and positive control (p = 0.001) were statistically significant. The Electrical Caries Monitor was also used as an objective measure of lesion severity. The end values increased from baseline to the three-month examinations, but none of the differences between the groups attained statistical significance. After six months, clinical hardness measures showed that only one lesion (0.7%) was worse than at the baseline examination-in the experimental group compared to 9.0% and 18.2% in the positive and negative control groups, respectively. In addition, 61.7%, 56.0%, and 27.0%, respectively, showed improvement for the three groups. The differences in the distribution of lesion change scores between the negative control group and both the experimental (p < 0.001) and positive control (p < 0.001) were statistically significant, as was the difference between the experimental group and the positive control (p = 0.006). The Electrical Caries Monitor end values for the experimental, positive, and negative control groups at the six-month examination were 7.9, 1.9 mega omega(s), and 387 kilo omegas(s), respectively. The differences between the negative control group and both the experimental (p < 0.001) and positive control (p < 0.001) were statistically significant. The difference between the experimental and positive control groups was also statistically significant (p = 0.03). CONCLUSION It is concluded that the new toothpaste containing 1.5% arginine and 1450 ppm fluoride, as sodium monofluorophosphate in a calcium base, provided greater anticaries benefits than a conventional toothpaste containing 1450 ppm fluoride. Both fluoride toothpastes demonstrated greater benefits than non-fluoride toothpaste.

Abstract
Abstract
Background: Surgical removal of primary breast cancer may result in subsequent alterations of host milieu. Massive clinical data have indicated that surgical extirpation favorably modifies the natural history for some patients, but it may also precipitate the metastatic outgrowth for others. Drainage fluid, harvested from a post-surgical wound, appears to be a physiological response to surgical trauma. However, few clinicians have recognized that the volume of wound drain might mirror the postoperative recurrence kinetics.
Methods: A total of 1439 patients were selected retrospectively from a large database of patients who underwent surgery between Jan 1, 2000 and Dec 31, 2002 in Fudan University Shanghai Cancer Center, Shanghai, China. The Spearman rank correlation analysis was conducted to evaluate the association between drainage volume of postoperative day 1 (POD1) and clinicopathological parameters, which included age at diagnosis, body weight at diagnosis, total number of excised axillary lymph nodes (ALNs), time to drainage volume less than 30ml (TTV30), total protein and albumin concentrations in serum. Survival curves were performed with Kaplan–Meier method and annual recurrence hazard was estimated by hazard function.
Results: Drainage volume of POD1 was positively correlated with age at diagnosis (Spearman's P < 0.001), weight at diagnosis (P <0 .001) and number of excised ALNs (P <0 .001) and TTV30 (P <0 .001), whereas it was inversely correlated with total protein concentration in serum (p = 0.028). We also observed that drainage volume of POD1 was significantly higher in patients with larger tumors (P < 0.001) and ALNs involvement (P = 0.030).
In the univariate survival analysis, there was less recurrence and death in patients with lower drainage volume of POD1 (both p = 0.006). Cox proportional hazards regression analysis revealed that drainage volume of POD1 was an independent predictor of recurrence-free survival (RFS; p = 0.035) and overall survival (OS; p = 0.047). Additionally, triple negative patients with larger volume of POD1 seemed to have poorer RFS (log-rank p = 0.022; Cox model P < 0.05) and OS (log-rank p = 0.015; Cox model P < 0.05).
Conclusions: Our study suggests that postsurgical drainage volume was strongly correlated with prognosis in breast cancer patients. The aim of this study was not only to enlighten novel prognostic factors, but also to infer that some host related characteristics such as extent of reaction to surgery play very important roles in the growth of micro-metastases. Therefore, integration of both host and tumor related factors be more precise to predict relapse risk than current modalities such as the St Gallen criteria, Oncotype-21 and Mammaprint etc. Further research on the underlying mechanism of this phenomena may lead the way to new adjuvant treatment targets and strategies.

Abstract
OBJECTIVES Pediatric obesity has become a significant public health concern. The historical focus in pediatric liver transplant (LT) has been undernutrition, with limited knowledge regarding obesity. Therefore, we sought to determine the prevalence of obesity in pediatric LT, compare it to National Health and Nutrition Examination Surveys (NHANES) data, and identify risk factors for obesity in pediatric LT. METHODS SPLIT, which collects pediatric LT data at 39 centers, was queried for subjects ages 2 to 18 years at follow-up, LT between 1995 and 2007, and with at least 1 body mass index measured 1 to 5 years after LT. RESULTS Of 1706 individuals included, 44% had biliary atresia (47% boys, 58% white, mean age at LT 4.6 years). Of these individuals, 19% were obese at 1 year and 18% at 3 years, higher than in the general pediatric population reported by 2003-2004 NHANES, whereas 11% obesity at 5 years after LT was similar to NHANES data. Using logistic regression, Hispanic ethnicity (odds ratio [OR] 1.8, 95% confidence interval [CI] 1.19-2.23), steroid use at follow-up (OR 1.48, 95% CI 1.23-1.77), overweight (OR 4.34, 95% CI 2.91-6.68), and obesity (OR 10.62, 95% CI 5.9-19.65) at LT independently predicted post-LT obesity. CONCLUSIONS These findings suggest a need to broaden standard care to include obesity assessment and intervention in routine pre- and posttransplant care.

Abstract
Interleukin-25 (IL-25 or IL-17E), a member of the structurally related IL-17 family, functions as an important mediator of T helper 2 cell-type (type 2) responses. We examined the cell type-specific role of IL-25-induced Act1-mediated signaling in protective immunity against helminth infection. Targeted Act1 deficiency in epithelial cells resulted in a marked delay in worm expulsion and abolished the expansion of the Lin(-)c-Kit(+) innate cell population in the mesenteric lymph node, lung, and liver. Th2 cell-inducing cytokine (IL-25 and IL-33) expression were reduced in the intestinal epithelial cells from the infected and IL-25-injected epithelial-specific Act1-deficient mice. Adoptive transfer of Lin(-)c-Kit(+) cells or combined injection of IL-25 and IL-33 restored the type 2 responses in these mice. Taken together, these results suggest that epithelial-specific Act1 mediates the expansion of the Lin(-)c-Kit(+) innate cell population through the positive-feedback loop of IL-25, initiating the type 2 immunity against helminth infection.

Abstract
Risk factors for chronic anemia in the post-transplant period have not been clearly delineated in pediatric liver transplant recipients. We analyzed data from children transplanted from 2000 to 2008 with at least two consecutive hemoglobin values from follow-up between six months and five yr post-transplant. A multivariate model was derived to determine independent risk factors associated with chronic anemia. Of 1026 children in this analysis, 242 (23.6%) were found to have chronic anemia. On multivariate analysis, GI bleeding (OR 11.83 [2.08-67.49], p = 0.0054), presence of leukopenia (OR 9.55 [95% CI 3.71-24.62], p < 0.0001), use of cyclosporine (OR 3.69, [95% CI 1.56-8.76], p = 0.0039) and corticosteroids (OR 2.90 [95% CI 1.94-4.33], p < 0.0001), and cGFR <90 mL/min/1.73 m(2) (OR 4.62 [95% CI 2.47-8.67], p < 0.0001) represented the most significant risk factors for chronic anemia. Use of antihypertensive medications (OR 1.89 [95% CI 1.23-2.91], p = 0.0039) was also significantly associated with a higher risk. In summary, chronic anemia is common in children following liver transplant. Our findings underscore the need to define the mechanisms by which these risk factors, some of which are modifiable, result in chronic anemia in pediatric liver transplant recipients.

Abstract
As pediatric liver transplant (LT) recipients come of age, additional insight into long-term medical complications of immunosuppression is warranted. The aims of this study were to estimate the prevalence of elevated blood pressure (BP) in long-term survivors of pediatric LT using the data from the Studies in Pediatric Liver Transplantation (SPLIT) database and to identify predictive factors. Patients enrolled in the BP arm of the SPLIT cohort participated in the study. All patients were of at least 5 years but ≤10 years post-LT. Automated BP measurements were obtained at anniversary visits. BP measures were classified as normal, borderline or elevated according to standard criteria. Patients taking antihypertensive medications were classified as "elevated." Eight hundred and fifteen patients participated. The prevalence of elevated BP measurements 5 to 10 years post-LT was 17.5 to 27.5%. Of total 62.5% patients presented with at least one additional elevated BP at a later follow up visit. Multivariate analysis revealed the following parameters to be predictive of elevated BP: age at transplant, steroid use at last BP measurement and cGFR at last BP measurement. Pediatric LT patients show a high prevalence of elevated BP measurements 5 to 10 years following LT, which is related to age at LT, decreased cGFR and recent steroid use.

Abstract
Abstract
Background: Hypoxia-inducible factor-1 (HIF-1) plays an important role in the development and progression of breast cancer. However, conflicting results have been yielded for the association between HIF-1 polymorphisms and breast cancer risk. Therefore, we carried out a meta-analysis to assess the association of HIF-1 1772 C/T and 1790 G/A polymorphisms with breast cancer.
Material and methods: Computerized and manual searches were performed to identify eligible studies comparing allelic and genotypic frequency between cases and controls in breast cancer. Odds ratios (ORs) were used to estimate the association between HIF-1 polymorphisms and breast cancer risk. The fixed-effects or random-effects model was used to combine data. Subgroup analyses by ethnicity were also performed.
Results: This meta-analysis for 1772 C/T polymorphism included 1934 breast cancer cases and 1848 controls, and for 1790 G/A polymorphism included 602 breast cancer cases and 479 controls. We found that 1772C/T polymorphism increased the risk of breast cancer in the recessive model (OR = 2.273, 95% CI: 1.061−4.872, P = 0.035), whereas similar effect failed to be observed in the dominant model (OR = 1.075, 95% CI: 0.717−1.613, P = 0.725). There was a significant increase in breast cancer risk among Asian women (OR = 4.162, 95% CI: 1.508−11.484, P = 0.006) but not Turkish patients in the recessive model. For the 1790G/A polymorphism, we found that it had no exact effect on the decreased risk of breast cancer in both recessive and dominant model.
Discussion: This meta-analysis indicates that the polymorphism of HIF-1 1772C/T rather than 1790G/A polymorphism might be one of the high risk factors for breast cancer. The effect of the 1772C/T polymorphism on breast cancer risk is completely generated by the Asian women.

Abstract
Abstract
Topoisomerase IIα is not only a proliferation marker of tumor cells but also a target for anthracycline-based chemotherapy. Both in vitro and in vivo studies have shown that there was a relationship between topo IIα and chemosensitivity to anthracyclines, but the predictive role of topo IIα is still controversial in breast cancer patients. A meta-analysis based on published studies was performed with the aim of obtaining an accurate evaluation of the association between topo IIα and sensitivity to anthracycline-based chemotherapy. A total of 13 eligible studies including 2,633 cases and 2,118 controls were identified. Topo IIα was associated with sensitivity to anthracyclines in locally advanced breast cancer patients who received neoadjuvant chemotherapy (RR = 1.93, 95%CI: 1.27−2.94, P=0.002; RR =1.98, 95%CI: 1.37−2.86, P<0.001). In early breast cancer patients who received anthracycline-based adjuvant chemotherapy compared with non-taxane-based polychemotherapy, amplification(HR = 0.64, 95%CI: 0.49−0.83, P=0.001; HR = 0.59, 95% CI: 0.35−1.01, P=0.056) or deletion (HR = 0.82, 95%CI: 0.67−1.00, P=0.051; HR =0.58, 95%CI: 0.35−0.97, P=0.036) of topo IIα was significantly associated with better RFS and OS. The subgroup analysis in the early breast cancer patients indicated that taxane could be an interference for evaluation of the predictive role of topo IIα. In summary, the present meta-analysis suggests that topo IIα is a predictive factor for breast cancer patients who received anthracycline-based chemotherapy. Larger and well-designed prospective studies are required to further evaluate the predictive role of topo IIα in clinical practice.

Abstract
Abstract
Background: The effect of zoledronic acid in breast cancer adjuvant therapy concerning improvement of patient survival has yet to be confirmed. We performed a meta-analysis of published and unpublished randomized controlled trials with the aim of accurate evaluation between clinical outcome and the association of the addition of zoledronic acid to adjuvant therapy.
Methods: We searched Pubmed (from 1966 to present) and online abstracts from the proceeding Annual Meetings of the American Society of Clinical Oncology (ASCO) (years 1992–2010) and online abstracts from San Antonio Breast Cancer Symposium (years 2004–2010). A total of five eligible studies including 3676 subjects and 3678 controls met our search criteria and were evaluated. Random and fixed-effects meta-analytical models were used where indicated, and between-study heterogeneity was assessed. The primary study endpoints were the DFS. Secondary endpoints were OS, distant or loco-regional recurrence free survival and bone metastasis free survival.
Results: Compared with the control arm, adjuvant breast cancer treatment with zoledronic acid did not significantly improve overall survival (OS), disease free survival (DFS), bone metastasis free survival, distant and locoregional recurrence free survival. However, in the postmenopausal subgroup, the addition of zoledronic acid to standard therapy could significantly improve DFS (RR=0.763, 95%CI 0.658−0.884, p<0.001) and reduce the risk of distant (RR=0.744, 95% CI 0.611−0.906, p=0.003) and locoregional recurrence (RR=0.508, 95% CI 0.340−0.760, p=0.001).
Discussion: Adjuvant zoledronic acid may potentially improve the prognosis of postmenopausal patients. Additional studies are needed to evaluate the value of adjuvant treatment of zoledronic acid in premenopausal couterparts, differing disease stages, and various pathological types of breast cancer.

Abstract
Interleukin-17 (IL-17) and IL-25 signaling induce the expression of genes encoding inflammatory factors and are implicated in the pathology of various inflammatory diseases. Nuclear factor κB (NF-κB) activator 1 (Act1) is an adaptor protein and E3 ubiquitin ligase that is critical for signaling by either IL-17 or IL-25, and it is recruited to their receptors (IL-17R and IL-25R) through heterotypic interactions between the SEFIR [SEF (similar expression to fibroblast growth factor genes) and IL-17R] domain of Act1 and that of the receptor. SEFIR domains have structural similarity with the Toll-IL-1 receptor (TIR) domains of Toll-like receptors and IL-1R. Whereas the BB' loop of TIR is required for TIR-TIR interactions, we found that deletion of the BB' loop from Act1 or IL-17RA (a common subunit of both IL-17R and IL-25R) did not affect Act1-IL-17RA interactions; rather, deletion of the CC' loop from Act1 or IL-17RA abolished the interaction between both proteins. Surface plasmon resonance measurements showed that a peptide corresponding to the CC' loop of Act1 bound directly to IL-17RA. A cell-permeable decoy peptide based on the CC' loop sequence inhibited IL-17- or IL-25-mediated signaling in vitro, as well as IL-17- and IL-25-induced pulmonary inflammation in mice. Together, these findings provide the molecular basis for the specificity of SEFIR-SEFIR versus TIR-TIR domain interactions and consequent signaling. Moreover, we suggest that the CC' loop motif of SEFIR domains is a promising target for therapeutic strategies against inflammatory diseases associated with IL-17 or IL-25 signaling.
