Abstract
OBJECTIVES To observe the potential protective effect of angiopoietin-1 (Ang-1) on rat choroidal neovascularization (CNV) leakage. METHODS The study was conducted at the Eye Institute of Shandong University of Traditional Chinese Medicine, Jinan, China from June 2012 to June 2013. Thirty CNV model rats were induced by laser. In vivo, fluorescein fundus angiography and pathological techniques were applied to detect the effect of vascular endothelial growth factor (VEGF) and Ang-1 intravitreous injection. In vitro, 3-(4, 5-dimethylthiazole-2-yl)-2, 5-biphenyl tetrazolium bromide (MTT) assay was applied to detect the proliferation of cultured bovine retinal endothelial cells (BRECs) after treatment with VEGF and Ang-1. Transmission electron microscopy (TEM) was used to detect the morphological changes under VEGF and Ang-1. RESULTS In the CNV rat model, less late leakage was found in the Ang-1 group than the vehicle control or the VEGF group. The MTT assay showed Ang-1 administration inhibited the proliferation of BRECs. The VEGF promoted proliferation at low concentrations and inhibited the proliferation when its concentration reached 50 ng/ml. The administration of VEGF+Ang-1 rescued the inhibition effect of Ang-1 alone. The TEM results showed that there were less intercellular junctions in the VEGF group compared with the vehicle control. In the VEGF + Ang-1 group, the intercellular junctions were nearly normal. CONCLUSION The Ang-1 can induce intercellular junction formation and decrease the CNV leakage.

Abstract
UNLABELLED This study gathered and processed the available air quality daily reports in 86 cities throughout China in 2001-2011. Urban air quality was assessed in terms of the evolution of the key pollutants, the pollution level, and the PM10 (particulate matter with an aerodynamic diameter < 10 microm) concentrations. The authors conclude that PM10 is the most important pollutant in Chinese cities, especially after the national sulfur dioxide (SO2) controls during the 11th Five Year Plan (FYP; 2006-2010). A notable advance was the reduction of extremely heavily polluted days with air pollution index (API) above 150 from 7% in 2001 to 1% in 2011 in the all-city average. In addition, the average API-derived PM10 concentrations continually decreased during the past 11 yr. Additionally, the pollution pattern of "more severe from south to north "in China became less obvious due to the decline of PM10 concentrations in the northern cities and the more obvious regional characteristics of air pollution. Nevertheless, more pollutants should be included in the API system to fully reflect the air quality status and guide future air pollution controls in Chinese cities. IMPLICATIONS Air quality daily report, the only publicly accessible observation database in the past decade, provides valuable insight into the air quality in Chinese cities. Using this data set, this paper assesses the status and change of urban air quality in China in 2001-2011, during which great effort was made to mitigate urban air pollution. It is valuable for the further refinement of national air quality control strategies, and the needs of updating the present daily report system are implicated.

Abstract
OBJECTIVE To assess whether the contributions of individual metabolic syndrome components to coronary heart disease (CHD) risk vary in patients with different glucose tolerance. METHODS A total of 1619 patients were included in this cross-sectional study. CHD, metabolic syndrome and glucose tolerance were assessed using coronary angiography, anthropometric and biochemical parameters, and an oral glucose tolerance test, respectively. Associations between CHD and components of metabolic syndrome were determined using logistic regression analysis. RESULTS Low high-density lipoprotein-cholesterol (HDL-C) was the only CHD risk factor in patients with both CHD and metabolic syndrome who had normal glucose tolerance, after adjustments for age, smoking and low-density lipoprotein-cholesterol (LDL-C) concentration. In patients with CHD plus metabolic syndrome and prediabetes, the most important risk factor was hypertension; additional risk factors were high postprandial blood glucose (PBG) and low HDL-C. In patients with CHD plus metabolic syndrome and diabetes, high PBG was the strongest risk factor, followed by hypertension, high FBG and high waist circumference. CONCLUSIONS Individual components of metabolic syndrome contributed variously to CHD across different glucose tolerance statuses.

Abstract
The amino acid metabolism in patients with hepatitis B virus (HBV) infection is significantly changed. In this study, we analyzed the relationship between the amino acid profiles and varying clinical stages of HBV infection, and investigated their significance. The plasma amino acid concentrations in 115 patients with HBV infection and 32 healthy donors were detected and analyzed, and the main indicators of liver function were measured. Correlation analysis was performed between the amino acid profiles (Fischer's ratio, branched-chain amino acid to tyrosine ratio [BTR]) and the key indicators of liver function in patients with HBV infection. Fisher's ratio and the BTR of patients with HBV infection was found to differ from that of the healthy controls, and was also found to significantly correlate with the stage of HBV infection. Changes in the BTR were closely related to the level of key indicators of liver function, and a significant relationship was detected between the Fischer's ratio and the BTR (r=0.928, p<0.001). These results suggest that Fischer's ratio and the BTR can indirectly reflect the degree of liver cell injury. Determining and tracking the plasma amino acid profiles could, therefore, be used for the diagnosis, treatment selection, and prognosis of patients with varying stages of HBV infection.

Abstract
Objective: To examine whether there is an association between the serum concentration of vaspin and the presence of carotid plaque in early stage type 2 diabetes mellitus (T2DM). Methods: Patients ( n = 61) with T2DM within 3 years of diagnosis were divided into those with and those without carotid plaque. Fasting serum vaspin levels, measured by enzymelinked immunosorbent assay, and blood pressure were compared between these two groups and also with an age-matched, apparently healthy control group ( n = 26). Results: Fasting serum vaspin concentrations were significantly higher in patients with T2DM without carotid plaque than in controls, but significantly lower in T2DM patients with carotid plaque than inthose without. Multivariate logistic regression analysis showed a significant positive association between the presence of carotid plaque and systolic blood pressure and a significant inverse association between the presence of carotid plaque and fasting serum vaspin concentration. Conclusion: A significant inverse association was found, in patients with T2DM within 3 years of diagnosis, between serum vaspin concentration and the presence of carotid plaque.

Abstract
Quantitation of individual monoclonal antibodies (mAbs) within a combined antibody drug product is required for preclinical and clinical drug development. We have developed two antitoxins, XOMA 3B and XOMA 3E, each consisting of three mAbs that neutralize type B and type E botulinum neurotoxin (BoNT/B and BoNT/E) to treat serotype B and E botulism. To develop mAb-specific binding assays for each antitoxin, we mapped the epitopes of the six mAbs. Each mAb bound an epitope on either the BoNT light chain (LC) or translocation domain (H(N)). Epitope mapping data were used to design LC-H(N) domains with orthogonal mutations to make them specific for only one mAb in either XOMA 3B or XOMA 3E. Mutant LC-H(N) domains were cloned, expressed, and purified from Escherichia coli. Each mAb bound only to its specific domain with affinity comparable to the binding to holotoxin. Further engineering of domains allowed construction of enzyme-linked immunosorbent assays (ELISAs) that could characterize the integrity, binding affinity, and identity of each of the six mAbs in XOMA 3B and 3E without interference from the three BoNT/A mAbs in XOMA 3AB. Such antigen engineering is a general method allowing quantitation and characterization of individual mAbs in a mAb cocktail that bind the same protein.

Abstract
BACKGROUND Cytokines are the important modulators that bind to their relevant receptors in response to some stimuli to mediate the homeostasis. It has been suggested that the imbalance of immune system of the host might affect the generation of diseases, including cancers. PATIENTS AND METHODS We investigated the association between six functional polymorphisms of IL-4, IL-13, and IL-4R genes and susceptibility to renal cell cancer in a hospital-based study, including 620 renal cell carcinoma (RCC) patients and 623 controls. Logistic regression model was used to assess the genetic effects on the development of RCC. RESULTS Overall, individuals with IL-4R Ile50Val CT/TT genotypes had a 0.34-fold significantly decreased RCC risk (CT/TT versus CC), and the T variant allele was associated with a decreased risk of RCC in a dose-response manner (Ptrend=0.009). In addition, we also observed that IL-13 C-1055T and Arg130Gln polymorphisms could decrease the risk of RCC [TT versus CC/CT odds ratio=0.36, 95% confidence interval (CI)=0.16-0.78; AA versus GG/GA: 0.66, 0.44-0.97, respectively]. Furthermore, a multiplicative interaction association between the combined IL-4R Ile50Val and IL-13 C-1055T genotypes was observed to decrease the risk of RCC (P=0.036). CONCLUSION IL-13 and IL-4R may play an important role in the etiology of RCC.

Abstract
Angiogenesis is required for invasive tumor growth and metastasis and constitutes an important point in the control of cancer progression. Its inhibition may be a valuable approach to cancer therapy. Antiangiogenic agents are designed to attack the tumor vasculature and cut off the tumor's supply of nutrients. Systemic blockade of angiogenesis has been recently approved for the treatment of several types of human cancers. Antiangiogenic therapy presents various advantages as compared to conventional treatment. Vascular endothelial growth factor (VEGF) is considered to be one of the most important regulators of angiogenesis and a key target in anticancer treatment. VEGF binding to its receptor (VEGFR) leads to cell proliferation and new vascular formation by tyrosine kinase (TK) pathway. VEGF/VEGFR pathway is becoming attractive target for anticancer drug design. It is believed to be important in the control of angiogenesis. Antiangiogenic therapy based on inhibition of VEGFR was reported to be powerful clinical strategies. In this review, the authors describe the existing literature regarding VEGFR inhibitors in the last few years. We attempt to cover all essential publications on the medicinal chemistry in terms of chemical structure, pharmacological profile and structure-activity relationships.

Abstract
BACKGROUND Most physiologic processes exhibit diurnal fluctuations controlled by the circadian regulation of sleep-wake behavior and feeding cycles. In addition, many cell types express endogenous circadian rhythms that affect cell-specific processes. Independent reports support the hypothesis that thrombopoietin (TPO) is under circadian control. OBJECTIVES The current study tested the hypothesis that CLOCK, a circadian transcription factor, may regulate Thpo, the gene encoding TPO. METHODS Circadian gene expression patterns were analyzed in mice and in human cell lines, Small interfering RNA was used to knock down CLOCK expression in cell lines, and gene expression was also examined in Clock(Δ19/Δ19) mutant mice. RESULTS It was found that there was a diurnal rhythm in the expression of Thpoin vivo in mice, and that this was associated with concomitant rhythms of protein abundance. Thpo was rhythmically expressed in human cell lines, consistent with the gene being directly or indirectly regulated by the circadian clock. Silencing of CLOCK in the Huh7 human hepatoma cell line led to a significant reduction in the rhythmicity of Thpo expression. The expression of Mpl in murine marrow also displayed diurnal rhythmicity in vivo. In Clock(Δ19/Δ19) mutant mice, Thpo and Mpl expression was disrupted and there was an increase in the number of mature megakaryocytes, but no change in the ploidy distribution within the megakaryocyte population. CONCLUSIONS These findings establish that Clock regulates Thpo and Mpl expression in vivo, and demonstrate an important link between the body's circadian timing mechanisms and megakaryopoiesis.

Abstract
Environmental contamination by energetic compounds is an increasing international concern, although little is known of their accumulation in and affect on wildlife. Reptiles are often good models for contaminants studies due to natural history traits that increase their potential for exposure. We report a study to assess accumulation and effects of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX, High Melting Explosive) in green anoles (Anolis carolinensis). Acute oral toxicity (LD(50)) was estimated to exceed 2000 mg/kg body weight in adult male and female anoles using a standard up-and-down method. Accumulation of HMX was assessed in adult females via dietary exposure and into eggs by two routes (directly from the soil and via maternal transfer). HMX readily accumulated into adult females in a dose-dependent manner and into eggs following both exposure pathways. However, total HMX in soil-exposed eggs was up to 40-times greater than those exposed via maternal transfer. Although there was a suggestion of an HMX-induced reduction in body weight in adult females, overall there were no effects observed over the 12 week exposure period. The only significant effect on eggs was a 50% reduction in hatching success for eggs exposed to 2000 mg/kg HMX in the soil during incubation. Growth and survival of hatchlings was not affected by HMX exposure. Our results demonstrate that HMX accumulates through the food chain and into eggs from the soil, but likely poses minimal threat to lizards except to hatching success in eggs incubated in soils with HMX levels near maximum environmental concentrations.
