Abstract
We report the first measurements of the kurtosis (κ), skewness (S), and variance (σ2) of net-proton multiplicity (Np-Np) distributions at midrapidity for Au+Au collisions at square root of s(NN)=19.6, 62.4, and 200 GeV corresponding to baryon chemical potentials (μB) between 200 and 20 MeV. Our measurements of the products κσ2 and Sσ, which can be related to theoretical calculations sensitive to baryon number susceptibilities and long-range correlations, are constant as functions of collision centrality. We compare these products with results from lattice QCD and various models without a critical point and study the square root of s(NN) dependence of κσ2. From the measurements at the three beam energies, we find no evidence for a critical point in the QCD phase diagram for μB below 200 MeV.

Abstract
We report the first three-particle coincidence measurement in pseudorapidity (Δη) between a high transverse momentum (p⊥) trigger particle and two lower p⊥ associated particles within azimuth |Δϕ|<0.7 in square root of s(NN)=200 GeV d+Au and Au+Au collisions. Charge ordering properties are exploited to separate the jetlike component and the ridge (long range Δη correlation). The results indicate that the correlation of ridge particles are uniform not only with respect to the trigger particle but also between themselves event by event in our measured Δη. In addition, the production of the ridge appears to be uncorrelated to the presence of the narrow jetlike component.

Abstract
BACKGROUND Extranodal nasal-type NK (natural killer)/T-cell lymphoma in elderly patients is rare, and its prognosis is unclear. This study aims to investigate the clinical characteristics and prognosis of this lymphoma. PATIENTS AND METHODS We analyzed 24 patients (age, >60 years old) with early-stage extranodal nasal-type NK/T-cell lymphoma. Among these patients, 23 received radiotherapy alone (n = 15) or radiotherapy and chemotherapy (n = 8) and 1 received chemotherapy alone. RESULTS Elderly patients with early-stage extranodal nasal-type NK/T-cell lymphoma were characterized by male predominance, good performance, large proportion of localized disease, more comorbidities, low-risk international prognostic index, and unfavorable prognosis. The 5-year cancer-specific survival (CSS), overall survival (OS), and progression-free survival (PFS) rates for all patients were 54.3%, 42.0%, and 40.2%, respectively. The 5-year CSS, OS, and PFS rates were 43.5%, 36.6%, and 34.1% in patients who received radiotherapy alone, and 50%, 50%, and 50% in patients who received radiotherapy and chemotherapy, respectively (P = 0.852 for CSS, P = 0.801 for OS, and P = 0.694 for PFS). Four patients died of treatment-related mortality. CONCLUSION Elderly patients with early-stage extranodal nasal-type NK/T-cell lymphoma exhibit poor prognosis and need special attention because of high treatment-related mortality.

Abstract
We studied the effects of schisandrol A (SCH) and gomisin A (GOM), two of the main bioactive components of Fructus Schisandrae chinensis, on cytochrome P450-3A4 (CYP3A4) activity and cellular glutathione (GSH) level. In a cell-free system both SCH and GOM inhibited CYP3A4 activity with IC(50) values of 32.02 microM and 1.39 microM, respectively. SCH or GOM at concentrations up to 100 microM did not alter cellular GSH level in regular HepG2 cells and P-glycoprotein overexpressing HepG2-DR cells. Since SCH and GOM may reverse multidrug resistance (MDR) by impeding the activity of P-glycoprotein, a membrane xenobiotic exporter, SCH or GOM could affect cellular drug metabolism in addition to drug uptake.

Abstract
In order to research the target of superior efficacy and lesser side effects, combination of herbal materials has been applied to phytotherapy for thousands of years in China and some other countries. Zuojin Wan (ZJW), a famous traditional Chinese medicine formula, is used in treating gastric diseases in China. It is composed of two herbs, Rhizoma Coptidis (RC) and Fructus Evodiae (FE) in the ratio of 6: 1(w/w). In the present study, we examined the effects of ZJW, RC, FE and active components isolated from these herbs on catecholamine (CA) secretion and intracellular calcium ([Ca(2+)](i)) in cultured bovine adrenal medullary cells. Extracts of ZJW and RC and berberine, palmatine and jatrorrhizine, components of RC, all inhibited CA secretion and rise in [Ca(2+)](i) induced by acetylcholine (ACh), veratridine (Ver) and/or 56 mM K(+). On the other hand, extract of FE, evodiamine and rutaecarpine, components of FE, stimulated CA secretion and rise in [Ca(2+)](i) induced by ACh. Furthermore, different proportions of RC and FE caused different responses in CA secretion. The present findings suggest that two herbs in ZJW have opposite effects, i.e., inhibitory effect of RC and stimulatory effect of FE, on CA secretion induced by acetylcholine in cultured bovine adrenal medullary cells.

Denosumab improves density and strength parameters as measured by QCT of the radius in postmenopausal women with low bone mineral density. Bone 2010; 47:131-9. [PMID: 20399288 DOI: 10.1016/j.bone.2010.04.594] [Citation(s) in RCA: 72] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2009] [Revised: 03/25/2010] [Accepted: 04/09/2010] [Indexed: 11/26/2022]
Abstract
BACKGROUND Bone strength is determined by both cortical and trabecular bone compartments and can be evaluated radiologically through measurement of bone density and geometry. Quantitative computed tomography (QCT) separately assesses cortical and trabecular bone reliably at various sites, including the distal radius where there is a gradation of cortical and trabecular bone. We evaluated the effect of denosumab, a fully human monoclonal antibody that inhibits RANK ligand, on distal radius QCT in women with low bone mass to assess the impact of this novel therapy separately on trabecular and cortical bone. METHODS Postmenopausal women (n=332) with spine areal bone mineral density (BMD) T-scores between -1.0 and -2.5 received denosumab 60 mg or placebo every 6 months during the 24-month study. QCT measurements along the distal radius were made using a whole-body computed tomography scanner and were used to determine the percentage change from baseline in volumetric BMD; volumetric bone mineral content (BMC); cortical thickness; volume; circumference; and density-weighted polar moment of inertia (PMI), a derived index of bone strength. RESULTS Denosumab treatment significantly increased total BMD and BMC along the radius (proximal, distal, and ultradistal sections). At 24 months, the ultradistal region had the greatest percentage increase in total BMD (4.7% [95% CI, 3.6-5.7]; P<0.001) and total BMC (5.7% [95% CI, 4.8-6.6]; P<0.001) over placebo. When cortical and trabecular bone at the proximal and distal regions were separately assessed, cortical bone had significant (P<0.001) increases in BMD, BMC, and thickness, and trabecular bone had a significant increase in BMD relative to placebo (P<0.05). Bone strength, estimated by density-weighted PMI, significantly increased compared with placebo after 6 months of treatment, with the largest percentage increase occurring at 24 months in the ultradistal region (6.6% [95% CI, 5.6-7.6]; P<0.0001). CONCLUSIONS QCT measurements demonstrated that denosumab significantly increased BMD, BMC, and PMI along the radius over 24 months. Additionally, denosumab prevented the decrease in QCT-measured cortical thickness observed in the placebo group. These data extend the evidence from previous dual-energy X-ray absorptiometry studies for a positive effect of denosumab on both the cortical and trabecular bone compartments and propose a possible mechanism for the reduction in fracture risk achieved with denosumab therapy.

Abstract
Previous studies have demonstrated that UVB radiation changes the epidermal permeability barrier and stratum corneum (SC) hydration. It is well known that sun exposure causes erythema, sunburn and melanoma. However, whether daily sun exposure alters SC integrity and epidermal permeability barrier function is largely unknown, especially in Chinese subjects. In the present study, we assess the SC integrity, SC hydration and epidermal permeability barrier function following various doses of sun exposure. A total of 258 subjects (124 males and 134 females) aged 18-50 years were enrolled. A multifunctional skin physiology monitor (Courage & Khazaka MPA5) was used to measure SC hydration and transepidermal water loss (TEWL) on the forearms. In males, basal TEWL was higher with higher doses of sun exposure than with lower doses and control, whereas in females, basal TEWL was higher with lower doses of sun exposure than with higher doses and control. In the group with higher doses of sun exposure, TEWL in females was significantly lower than that in males. The barrier recovery was faster in females than in males in both control and lower-dose groups. In both males and females, barrier recovery was delayed with higher doses of sun exposure. In males, sun exposure did not alter SC hydration, while in females SC hydration was lower with lower doses of sun exposure as compared with control and higher doses of sun exposure. These results demonstrated that sun-induced changes in SC function and SC hydration vary with gender and the extent of sun exposure.

Abstract
Hyperhomocysteinemia (HHcy) has been recognized as a risk factor for developing Alzheimer's disease (AD). However, its underlying molecular mechanisms are still elusive. Here we show that HHcy induces an elevation of amyloid beta (Abeta) levels and deposition, as well as behavioral impairments, in a mouse model of AD-like amyloidosis, the Tg2576 mice. This elevation is not associated with significant change of the steady state levels of the Abeta precursor protein (APP), beta- or alpha-secretase pathways, nor with the Abeta catabolic pathways. By contrast, HHcy significantly reduces glycogen synthase kinase 3 (GSK3) Ser21/9 phosphorylation, but not total GSK3 protein levels. Similar results are obtained in brains homogenates from a genetic mouse model of HHcy. In vitro studies show that homocysteine increases Abeta formation, reduces phosphorylated GSK3 levels, without changes in total APP and its metabolism, and these effects are prevented by selective GSK3 inhibition. Overall, these data support a potential link between GSK3 and the pro-amyloidotic effect of HHcy in vivo and in vitro.

Abstract
Proline oxidase (POX) is a novel mitochondrial tumor suppressor that can suppress proliferation and induce apoptosis through the generation of reactive oxygen species (ROS) and decreasing hypoxia-inducible factor (HIF) signaling. Recent studies have shown the absence of expression of POX in human cancer tissues, including renal cancer. However, the mechanism for the loss of POX remains obscure. No genetic or epigenetic variation of POX gene was found. In this study, we identified the upregulated miR-23b in renal cancer as an important regulator of POX. Ectopic overexpression of miR-23b in normal renal cells resulted in striking downregulation of POX, whereas POX expression increased markedly when endogenous miR-23b was knocked down by its antagomirs in renal cancer cells. Consistent with the POX-mediated tumor suppression pathway, these antagomirs induced ROS, inhibited HIF signaling and increased apoptosis. Furthermore, we confirmed the regulation of miR-23b on POX and its function in the DLD1 Tet-off POX cell system. Using a luciferase reporter system, we verified the direct binding of miR-23b to the POX mRNA 3'-untranslated region. In addition, pairs of human renal carcinoma and normal tissues showed a negative correlation between miR-23b and POX protein expression, providing its clinical corroboration. Taken together, our results suggested that miR-23b, by targeting POX, could function as an oncogene; decreasing miR-23b expression may prove to be an effective way of inhibiting kidney tumor growth.

Abstract
LBA4507 Background: Bone metastases from hormone-refractory (castration-resistant) prostate cancer (CRPC) are associated with RANKL-mediated osteoclast activation resulting in bone destruction and skeletal-related events (SRE). Denosumab is a fully human monoclonal antibody against RANKL. This phase III, randomized, double-blind, active-controlled trial compared the efficacy and safety of denosumab vs. zoledronic acid (ZA) in patients with metastatic CRPC. Methods: Patients (n = 1,901) with CRPC and at least 1 bone metastasis, but no prior IV bisphosphonate use, received either SC denosumab 120 mg and IV placebo (n = 950), or SC placebo and IV ZA 4 mg (n = 951) adjusted for creatinine clearance every 4 weeks. All patients were instructed to take supplemental calcium and vitamin D. The primary endpoint was time to first on-study SRE, defined as pathologic fracture, radiation or surgery to bone, or spinal cord compression. Results: Denosumab significantly delayed the time to first on-study SRE compared with ZA, (HR 0.82 ; 95% CI: 0.71, 0.95 ; p = 0.008.) The median time to first on-study SRE was 20.7 mo denosumab vs. 17.1 mo ZA, a difference of 3.6 months. Denosumab also significantly delayed the time to first and subsequent on-study SRE (multiple event analysis) (HR 0.82 ; 95% CI: 0.71, 0.94 ; p = 0.004). Greater suppression of the bone turnover markers uNTx and BSAP occurred in denosumab patients compared with ZA (p < 0.0001 for both). Overall, adverse event (AE) rates (97% each) and serious AEs (63% denosumab, 60% ZA) were similar, irrespective of potential relationship to study drugs. AEs of hypocalcemia were reported in 13% and 6% of denosumab and ZA patients. Osteonecrosis of the jaw occurred in 22 (2.3%) denosumab compared with 12 (1.3%) ZA patients (p = 0.09). Overall survival (HR 1.03 ; 95% CI: 0.91, 1.17 ; p = 0.65) and time to cancer progression (HR 1.06; 95% CI: 0.95, 1.18; p = 0.30) were similar between treatment arms. Conclusions: Denosumab demonstrated superiority over ZA in delaying or preventing SREs in patients with bone metastases from CRPC. Adverse events were consistent in both treatment groups with those previously reported in advanced cancer populations. [Table: see text]

Abstract
UNLABELLED Receptor for advanced glycation end products (RAGE) may be involved in the pathogenesis of cancer progression. Pathological effects mediated via RAGE are physiologically inhibited by soluble RAGE (sRAGE). The aim of this study was to identify sRAGE and RAGE expression profile in lung cancer patients. An ELISA method was used to quantify serum sRAGE in 45 individuals. Additionally, surgical specimens of 28 lung cancer patients were also included for RAGE expression by immunohistochemistry. Serum sRAGE was significantly decreased in lung cancer patients compared with controls (vs. healthy donors, P=0.034; vs. pulmonary tuberculosis patients, P=0.010). Lower sRAGE concentration was negative correlated with lymph node involvement (N0 vs. N1-2, P=0.028). Down regulation of membranous and cytoplasmic expression for RAGE was also lower in lung cancer tissue than in nearby normal lung tissue. Correlation with serum sRAGE concentration and RAGE expression in lung cancer tissue was existed by CV values. The results indicate that serum sRAGE levels are decreased during lung cancer progression and could reflect decreased RAGE expression in tissue. Serum sRAGE may serve as an effective and convenient diagnostic biomarker for lung cancer. KEYWORDS sRAGE, serum, RAGE, tissue, lung cancer.

Abstract
BACKGROUND Previously, expression profiling has been used to analyse allergen-challenged T-helper type 2 cells, nasal biopsies and nasal fluid cells from patients with seasonal allergic rhinitis (SAR). Allergen-challenged peripheral blood mononuclear cells (PBMCs) provide a human in vitro model of how antigen-presenting cells, CD4+ T cells and effector cells such as basophils interact in allergic inflammation. OBJECTIVE To identify novel genes and pathways in allergen-challenged PBMCs from patients with SAR using gene expression profiling and functional studies. METHODS PBMCs from 11 patients with SAR and 23 healthy controls were analysed with gene expression profiling. mRNA expression of IL17RB in basophils was evaluated using quantitative real-time PCR. Membrane protein expression and apoptosis of basophils were examined by flow cytometry. Degranulation of basophils was assessed by measuring beta-hexosaminidase release. Cytokine release was measured using ELISA. RESULTS Gene expression microarray analysis of allergen-challenged PBMCs showed that 209 out of 44000 genes were differentially expressed in patients compared with controls. IL17RB was the gene whose expression increased most in patients (P<0.0001). FACS analysis of PBMCs showed, for the first time, that basophils express IL-17RB. Following allergen challenge, IL-17RB protein increased significantly on basophils from patients compared with controls (P<0.05). IL-3 significantly increased both mRNA and protein expressions of IL17RB. Activation of IL-17RB by its ligand, IL-25, inhibited apoptosis of basophils. Moreover, IgE-mediated degranulation was enhanced by IL-25. CONCLUSION Increased expression of IL-17RB on allergen-challenged basophil is regulated by IL-3, inhibits apoptosis and promotes IgE-mediated degranulation of basophils.

Abstract
Alpha 7 nicotinic acetylcholine receptor, a kind of ligand-gated ion channel mainly expressed in macrophages, plays a crucial role in improving survival in sepsis via suppressing proinflammatory cytokines. The predisposition of genomic polymorphisms within alpha 7 nicotinic acetylcholine receptor gene (CHRNA7) to sepsis has not been investigated. The current association study was performed to analyse six common genetic variations within 5'-upstream region of CHRNA7 gene in 229 patients with severe sepsis and 267 controls. Neither allelic frequencies nor genotype distributions were significantly different between patients and controls, as well as between surviving and nonsurviving patients. The frequencies of estimated haplotypes were also comparable between above defined groups. The present study suggests that genomic polymorphisms in the 5'-upstream region of CHRNA7 gene may not be a major risk factor for severe sepsis in Chinese Han population.

Abstract
UNLABELLED Field experiments were conducted in five homes during three seasons (summer 2005, summer 2006 and winter 2007) to quantify ozone-initiated secondary aldehyde yields, surface reaction probabilities, and trends any temporal over a 1.5-year interval. Surfaces examined include living room carpets, bedroom carpets, kitchen floors, kitchen counters, and living room walls. Reaction probabilities for all surfaces for all seasons ranged from 9.4 x 10(-8) to 1.0 x 10(-4). There were no significant temporal trends in reaction probabilities for any surfaces from summer 2005 to summer 2006, nor over the entire 1.5-year period, indicating that it may take significantly longer than this period for surfaces to exhibit any 'ozone aging' or lowering of ozone-surface reactivity. However, all surfaces in three houses exhibited a significant decrease in reaction probabilities from summer 2006 to winter 2007. The total yield of aldehydes for the summer of 2005 were nearly identical to that for summer of 2006, but were significantly higher than for winter 2007. We also observed that older carpets were consistently less reactive than in newer carpets, but that countertops remained consistently reactive, probably because of occupant activities such as cooking and cleaning. PRACTICAL IMPLICATIONS Ozone reactions taking place at indoor surfaces significantly influence personal exposure to ozone and volatile reaction products. These field studies show that indoor surfaces only slowly lose their ability to react with ozone over several year time frames, and that this is probably because of a combination of large reservoirs of reactive coatings and periodic additions of reactive coatings in the form of cooking, cleaning, and skin-oil residues. When considering exposure to ozone and its reaction products and in the absence of dramatic changes in occupancy, activities or furnishings, indoor surface reactivity is expected to change very slowly.

Abstract
AIM Reducing lung injury during cardiopulmonary bypass (CPB) is important for patients' recovery. The present study was designed to evaluate the effects of pulmonary artery perfusion pressure on the extent of lung injury during CPB in an animal model. METHODS Twenty healthy mongrel dogs were randomly divided into four groups, including a control group and three perfusion groups designed to simulate clinical cardiopulmonary bypass-induced lung injury. During pulmonary ischemia and cardiopulmonary bypass, protective perfusions were performed using different perfusion pressures (15-20, 25-30, and 40-45 mmHg), while animals in the control group were not perfused. After pulmonary reperfusion, the changes in pulmonary function and tissue histopathology were determined. RESULTS Compared with the control group, lung compliance, oxygenation and vascular resistance after reperfusion were significantly improved in both low- and moderate-pressure groups. The malonaldehyde concentration, neutrophil sequestration ratio, and expression of ICAM-1 were also decreased significantly in the two groups. However, there were no significant differences in any of these parameters between the control group and the high-pressure group. Histopathological examination demonstrated that there were obvious inflammatory cell infiltration and tissue damage in the control and high-pressure groups, which was prevented in the low- and moderate-pressure groups. CONCLUSION The perfusion pressure is an important factor that determines the extent of lung protection, and the use of pressures below 30 mmHg is optimal, with the safest and most effective range being 15-20 mmHg.
