Abstract
BACKGROUND Allergic Rhinitis Control Test (ARCT) has been validated for assessing allergic rhinitis (AR) control and identifying severe AR. The aim of the study was to assess the ARCT questionnaire as a tool for stepwise pharmacotherapy. METHODS A standard pharmacotherapy regimen from Step 1 (oral second-generation H1 antihistamine as needed) to Step 5 (oral corticosteroid) was carried out prospectively in a Chinese AR population. The AR patients were initiated with Allergic Rhinitis and its Impact on Asthma (ARIA) appropriate step treatment and assessed with ARCT every 15 days. If ARCT score was equal or above 20 (controlled AR) and maintained for 15 days, the patient would finish the study; if ARCT score was strictly <20 (uncontrolled AR), the patient would receive higher step treatment according to a predefined open design up to Step 5. The different AR control subgroups were compared. RESULTS A total of 255 patients were enrolled in the study; 5 patients dropped out and 2 (0.8%) were controlled at day 0, 85 (34.0%) at day 15, 177 (70.8%) at day 30, 222 (88.8%) at day 45, 241 (96.4%) at day 60 and 242 (96.8%) at day 75. Only 8 (3.2%) patients remained uncontrolled at the endpoint of the study. Patients with ARIA moderate/severe or persistent symptoms, moderate/severe impaired quality of life, asthma history, rhinorrhea and cough symptoms always needed up to Step 4 (nasal corticosteroid plus antihistamine) and prolonged treatments to achieve disease control. CONCLUSIONS The majority of AR can be controlled with standard stepwise treatment. ARCT offers an objective criterion for the stepwise pharmacotherapy of AR.

Abstract
The complement system plays a critical role in ischemia-reperfusion injury (IRI)-mediated delayed graft function (DGF). To better understand the roles of complement activation pathways in IRI in kidney transplantation, donor kidneys were treated ex vivo with terminal complement pathway (TP) inhibitor, anti-rat C5 mAb 18A10, or complement alternative pathway (AP) inhibitor TT30 for 28 h at 4°C pretransplantation in a syngeneic kidney transplantation rat model. All 18A10- and 67% of TT30-pretreated grafts, but only 16.7% of isotype control-pretreated grafts, survived beyond day 21 (p < 0.01). Inhibitor treatment in the final 45 min of 28-h cold ischemia (CI) similarly improved graft survival. Systemic posttransplant treatment with 18A10 resulted in 60% increased graft survival beyond day 21 (p < 0.01), while no TT30-treated rat survived > 6 days. Our results demonstrate that AP plays a prominent role during CI and that blocking either the AP or, more effectively the TP prevents ischemic injury and subsequent DGF. Multiple complement pathways may be activated and contribute to reperfusion injury; blocking the TP, but not the AP, posttransplant is effective in preventing reperfusion injury and increasing graft survival. These results demonstrate the feasibility of using complement inhibitors for prevention of DGF in humans.

Abstract
Phototherapy has been widely used in treating neonatal jaundice, but detailed metabonomic profiles of neonatal jaundice patients and response to phototherapy have not been characterized. Our aim was to depict the serum metabolic characteristics of neonatal jaundice patients relative to controls and changes in response to phototherapy. A (1) H nuclear magnetic resonance (NMR)-based metabonomic approach was employed to study the metabolic profiling of serum from healthy infants (n = 25) and from infants with neonatal jaundice (n = 30) pre- and postphototherapy. The acquired data were processed by multivariate principal component analysis (PCA) and orthogonal partial least-squares-discriminant analysis (OPLS-DA). The PLS-DA and OPLS-DA model identified nine metabolites capable of distinguishing patients from controls. In addition, 28 metabolites such as β-glucose, α-glucose, valine, and pyruvate changed in response to phototherapy. This study offers useful information on metabolic disorders in neonatal jaundice patients and the effects of phototherapy on lipids, amino acid, and energy metabolism.

Abstract
In the current study, we discovered that Hoechst 33342 (H342) could produce significant toxicity to the human neuroblastoma SK-N-SH cells at concentrations typically used to identify side population (SP) cells. At 3.75 and 5 µg/ml, H342 induced cell death and apoptosis. Flow cytometry analysis revealed cell cycle arrest at S-phase. Our findings caution against using H342 for SP analysis without considering differential susceptibility of different cells to H342. Specifically, concentration of H342 needs to be adjusted carefully to minimize toxicity for each cell line.

Abstract
BACKGROUND The pathophysiological mechanisms for atrial fibrillation (AF) vulnerability in diabetic patients are largely unclear. AIM To investigate the high risk factors of AF in Chinese Kailuan diabetes. DESIGN A retrospective review of AF in Chinese Kailuan diabetes. METHODS Research and statistic analysis on the clinical data of 9050 diabetic patients from Kailuan Coal Mine Group Corporation who participated in a health survey from July 2006 to October 2007. RESULTS Sixty diabetic patients (50 males and 10 females) were diagnosed with AF during the health checkup, with a prevalence of 0.66% (0.67% in males and 0.62% in females). Univariate analysis showed that patients with AF were older and had higher levels of serum uric acid (UA), pulse pressure, serum c-reactive protein and anti-hypertensive medication usage, but lower levels of fasting blood glucose and triglycerides (TG). Multivariate analysis indicated that older age (OR = 1.09; 95% CI: 1.06-1.12), increased UA (OR = 1.01; 95% CI: 1.00-1.01) and decreased TG (OR = 0.71; 95% CI: 0.55-0.92) were independent predictive factors of AF after adjusting for other variables. After gender stratification, age and UA remained as independent predictive factors of AF in both male and female patients. However, TG had an independent inverse association with AF in male patients only. CONCLUSIONS Age and UA are independent predictive factors of AF in both male and female diabetic patients. TG is inversely correlated with AF in male diabetic patients only.

Abstract
OBJECTIVES This study aimed to investigate effects of neurotrophin receptor-mediated melanoma antigen-encoding gene homology (NRAGE) on proliferation and odontoblastic differentiation of mouse dental pulp cells (mDPCs). MATERIALS AND METHODS Mouse dental pulp cells were infected with recombinant lentivirus to stably knockdown expression of NRAGE, and biological effects of NRAGE on the cells were detected. Proliferation and odontoblastic differentiation of mDPCs were observed. Simultaneously, mRNA and protein levels of NRAGE and nuclear factor-κB (NF-κB) protein expression were detected. Immunofluorescence assay was used to detect expression and location of NRAGE and NF-κB. RESULTS NRAGE mRNA and protein levels reduced significantly after mDPC odontoblastic induction. Knockdown of NRAGE inhibited the proliferation of mDPCs. However, knockdown of NRAGE enhanced their odontoblastic differentiation with up-regulated ALPase activity. It also promoted mineral nodule formation as well as mRNA and protein expressions of ALP, DSPP and DMP1. Protein levels of NF-κB/p50 significantly increased, whereas NF-κB/p105 protein expression decreased in the mDPC/shNRG group. Immunofluorescence revealed that relocation of NF-κB was similar to that of NRAGE during odontoblastic induction, in which NF-κB translocated from the cytoplasm to the nucleus. CONCLUSION NRAGE is a potent regulator of proliferation and odontoblastic differentiation of mDPCs, which might be via the NF-κB signalling pathway.

Abstract
Transplant vasculopathy is associated with neointimal accumulation of recipient-derived mesenchymal stem cells. Increased circulating levels of LG3, a C-terminal fragment of perlecan, were found in renal transplant patients with vascular rejection. Here, we evaluated whether LG3 regulates the migration and homing of mesenchymal stem cells and the accumulation of recipient-derived neointimal cells. Mice were transplanted with a fully-MHC mismatched aortic graft followed by intravenous injection of recombinant LG3. LG3 injections increased neointimal accumulation of α-smooth muscle actin positive cells. When green fluorescent protein (GFP)-transgenic mice were used as recipients, LG3 injection favored accumulation of GFP+ cells to sites of neointima formation. LG3 increased horizontal migration and transmigration of mouse and human MSC in vitro and led to increased ERK1/2 phosphorylation. Neutralizing β1 integrin antibodies or use of mesenchymal stem cells from α2 integrin-/- mice decreased migration in response to recombinant LG3. Reduced intima-media ratios and decreased numbers of neointimal cells showing ERK1/2 phosphorylation were found in α2-/- recipients injected with recombinant LG3. Collectively, our results suggest that LG3, through interactions with α2β1 integrins on recipient-derived cells leading to activation of ERK1/2 and increased migration, favors myointimal thickening.
