Abstract
SHP2 participates in multiple signaling events by mediating T-cell development and function, and regulates cytokine-dependent granulopoiesis. To explore whether and how SHP2 can regulate bone-marrow eosinophil differentiation, we investigate the contribution of SHP2 in the bone-marrow eosinophil development in allergic mice. Blockade of SHP2 function by SHP2 inhibitor PHPS-1 or conditional shp2 knockdown by adenovirus-inhibited bone-marrow-derived eosinophil differentiation in vitro, with no detectable effects on the apoptosis of eosinophils. Furthermore, SHP2 induced eosinophil differentiation via regulation of the extracellular signal-regulated kinase pathway. Myeloid shp2 conditional knockout mice (LysMcreshp2flox/flox) failed to induce eosinophilia as well as airway hyper-responsiveness. The SHP2 inhibitor PHPS-1 also alleviated eosinophilic airway inflammation and airway hyper-responsiveness, accompanied by significantly reduced levels of systemic eosinophils and eosinophil lineage-committed progenitors in allergic mice. We demonstrate that inhibition of eosinophil development is SHP2-dependent and SHP2 is sufficient to promote eosinophil formation in vivo. Our data reveal SHP2 as a critical regulator of eosinophil differentiation, and inhibition of SHP2 specifically in myeloid cells alleviates allergic airway inflammation.

Abstract
Triflusal presents comparable antiplatelet activity to aspirin while presenting a more favourable safety profile, and is used in the treatment of thrombosis. The study aimed to evaluate the pharmacokinetics and safety of triflusal and its major metabolite 2-(hydroxyl)-4-(trifluoromethyl)- benzoic acid (HTB) in healthy Chinese subjects.30 healthy subjects were recruited in this randomized, single-center, and open-label, parallel, single ascending doses (300, 600, 900 mg) and multiple doses (600 mg, once daily for 7 days) study. Plasma samples were analyzed with a validated liquid chromatography tandem mass spectrometry (LC/MS/MS) method. Safety was assessed by adverse events, ECG, laboratory testing, and vital signs.Triflusal was safe and well tolerated. After single-dose administration, triflusal was rapidly absorbed with a mean Tmax of 0.55-0.92 h and a mean t1/2 kel of 0.35-0.65 h, HTB was absorbed with a mean Tmax of 2.35-3.03 h and a mean t1/2 kel of 52.5-65.57 h. Cmax and AUC for triflusal and HTB were approximately dose proportional over the 300-900 mg dose range. In the steady state, the accumulation index (R) indicated that the exposure of triflusal increased slightly with repeated dosing, and the exposure of HTB increased obviously. 3 adverse events certainly related to the investigational drugs occurred in the multiple-dose phase.Following oral dosing under fasting condition, triflusal is promptly absorbed and rapidly depleted from the systemic circulation. HTB is quickly generated from triflusal and slowly eliminated. Triflusal accumulates slightly in the body. HTB plasma concentration builds up progressively toward steady-state.

Abstract
Hypomethylation of the O6-methylguanine-DNA-methyltransferase (MGMT) promoter in glioma cells has been associated with temozolomide resistance. S-adenosylmethionine (SAM), which is produced during folate metabolism, is the main source of methyl groups during DNA methylation. As a key enzyme during folate metabolism, polymorphisms of 5,10-methylenetetrahydrofolate reductase (MTHFR) may regulate folate end-products. We investigated the effect of typical polymorphisms of MTHFR (C677T and A1298C) on MGMT methylation based on different serum folate levels in patients with glioma from Northeast China. A total of 275 patients with glioma and 329 without malignant tumors were tested. Serum folate concentration was assayed by using the electrochemiluminescence immunoassay. MTHFR polymorphisms were detected by Taqman-Fluorescence quantitative polymerase chain reaction (PCR). Methylation-specific PCR was used to assess MGMT methylation. The constituent ratio of glioma patients below the serum folate biological reference value was significantly higher than that of the control population (P < 0.001). In patients with oligodendroglioma and glioblastoma, heterozygotes for the A1298C mutation were found in higher frequency than homozygotes or wild types (oligodendroglioma, P < 0.001; glioblastoma, P < 0.01). When grouped by the median or biological reference value of serum folate, only homozygotes for C677T with low levels of folate were significantly associated with decreased methylation of MGMT (median, P < 0.001; biological reference value, P = 0.036). These data suggest that, in combination with a negative folate balance in glioma patients, T/T genotypes in MTHFR C677T may be associated with MGMT demethylation.

Abstract
OBJECTIVE Landiolol is an ultra-short-acting β-blocker that appears to be more cardioselective and less toxic than esmolol. The main objective of this study was to investigate the pharmacokinetics, pharmacodynamics, and safety of landiolol hydrochloride in healthy Chinese volunteers. METHODS We set 2-dose regimen (L and H groups) [L (low): 0.125 mg/kg/min (1 min) loading→0.02 mg/kg/min (20 min) continuous, H (high): 0.25 mg/kg/min (1 min) loading→0.04 mg/kg/min (20 min) continuous]. 20 healthy subjects of either sex were allocated randomly to the L and H groups (n=10, and 10). Blood samples were collected over 1 h after continuous infusion and were determined using a validated liquid chromatography/mass spectrometry (LC/MS/MS) assay. The safety of landiolol hydrochloride was assessed by adverse events recording, 12-lead ECG findings, physical examination, laboratory testing, and vital signs. RESULTS The main pharmacokinetic parameters of landiolol hydrochloride in healthy Chinese subjects were as follows: doses of 2 groups (L and H); Cmax of 400±110 and 731±246 ng/mL; C21min of 327±109 and 508±141 ng/mL; Tmax of 10.1±6.5 and 6.2±5.7 min; t1/2 of 4.7±1.6 and 6.5±1.7 min. Landiolol hydrochloride was safe. There were no adverse events in any subject. The heart rates and blood pressures of subjects administered landiolol hydrochloride decreased, but no clinically significant changes were observed. CONCLUSION The concentration of landiolol hydrochloride rapidly reached steady state levels, and rapidly dissipated after completion of administration. Landiolol hydrochloride appears to have rapid onset and short action.

Abstract
BACKGROUND Neonatal Bacillus Calmette-Guérin (BCG) vaccination induces vigorous T-helper type 1 (Th1) responses and inhibits allergy-related airway dysfunction, but the exact mechanisms remain unclear. The objective of this study was to address where the Th1 cells induced by neonatal BCG vaccination are generated and stored, and how they are recruited into the inflamed airway for the prevention of allergen-induced airway inflammation. METHODS We vaccinated neonatal C57BL/6 mice with BCG in a mouse model of asthma and analyzed the expression and function of Th1 cells in vivo and in vitro. RESULTS BCG vaccination-induced Th1 cells in the local inguinal lymph nodes (ILN) migrated into the lungs upon inhaled ovalbumin (OVA) challenge in OVA-sensitized mice. These CD4(+) T cells in the ILN exhibited potentials of activation, proliferation and cytokine secretion and expressed high levels of CXCR3. Adoptive transfer of CD4(+) T cells from BCG-treated ILN significantly decreased allergic airway responses. In addition, the protective effect of BCG vaccination against allergic airway inflammation was lost upon the excision of the ILN. CONCLUSIONS These data demonstrate that ILN serves as a 'weapon' pool of Th1 cells following BCG vaccination, and these cells are ready for the migration into the inflamed lungs upon the allergen challenge, thereby inhibiting allergen-induced airway disorder.

Abstract
OBJECTIVES This study measured the serum concentrations of resistin and adiponectin in Chinese subjects with impaired glucose tolerance (IGT) and investigated their association with insulin resistance, metabolic parameters and circulating inflammatory markers. METHODS A total of 124 subjects participated in the study (44 with IGT and 80 with normal glucose tolerance [NGT]). Fasting serum concentrations of lipids, glucose, insulin and adipocytokines (resistin, adiponectin, leptin, tumour necrosis factor-α [TNF-α], interleukin-6 and C-reactive protein) were measured. RESULTS Serum resistin concentrations were similar in the IGT and NGT groups but were significantly higher in overweight/ obese IGT subjects than in those of normal weight. Serum adiponectin concentrations were significantly lower in the IGT group than in the NGT group. In the IGT group, resistin was positively correlated with age, body mass index and TNF-α, and adiponectin was correlated positively with high-density lipoprotein cholesterol and negatively with TNF-α and waist/hip ratio. CONCLUSIONS Circulating resistin is unlikely to be a major mediator of glucose tolerance in humans but it may have an inflammatory role in IGT. The data support the theory that circulating adiponectin has an anti-inflammatory and anti-insulin resistance function.

Abstract
The study used network analysis to identify forms and sources of social support associated with a medical services use among a medically underserved population living with HIV/AIDS. Participants were African American former or current injection drug users (n=295; 34% female, 45% current drug users and 17% AIDS diagnosed). Outcomes were access to the same medical provider, use of outpatient services and emergency room (ER) use with or without subsequent hospitalization. Controlling for AIDS diagnosis, insurance, current drug use and gender, access to the same medical care provider was associated with more females in one's support network and more network sources of emotional support, financial support and instrumental assistance. Adjusting for confounders, outpatient service use was associated with more female support network members and more sources of emotional support. Controlling for participants' drug use and insurance, sub-optimal emergency department use was associated with greater number of active drug users in one's support network. Contrary to other study findings, having a supportive sex partner was associated with lower access to medical care, and kin support was not associated with medical service use. Results indicate that specific sources and forms of social support had differential influences on the sample's utilization of medical services. The findings suggest that promoting HIV-positive African American injection drug users' support network functioning may help improve HIV medical services utilization among this medically underserved population.

Abstract
The physics of the heat conduction and viscous dissipation in rarefied gases is analyzed and discussed. A heat transfer model valid for arbitrary Knudsen numbers, defined as the ratio of the molecular mean free path to the characteristic length of channels, is derived by treating the heat transfer behavior in the slip and transition regimes as an intermediate function of continuum heat transfer model and free molecular heat transfer model. Comparison studies reveal that this model not only shows good agreement with the numerical results based on the direct simulation Monte Carlo method, but also has some unique features that can overcome the deficiencies existing in the previous models. Therefore, this model is capable to study the heat transport phenomena in very dilute gas Couette flows through micro/nanochannels more accurately.

Abstract
A set of resonant inelastic X-ray scattering (RIXS) studies focusing on the 2p64f(n)-->2p54f(n)5d1(2p54f(n+1)5d0)-->2p63d94f(n)5d1(2p63d94f(n+1)5d0) channel of dysprosium in Dy metal, Dy2O3, DyNi3 and Dy25Fe18 compounds have been carried out. Data showed with high statistics and resolution, the different delocalization degree of the 5d band of dysprosium in these compounds, e.g., decreasing from Dy metal to DyNi3, Dy25Fe18 and to dysprosium oxide, in agreement with the high-resolution XANES (HRXANES) spectra. Band structure calculations performed on Dy metal and Dy2O3 confirm both RIXS and HRXANES results in the increasing delocalization of the dysprosium 5d band in Dy metal with respect to Dy2O3. The 5d orbital occupancies of DyNi3 and Dy25Fe18 alloys have been also studied by comparison of the HRXANES white line (WL) area with the behavior of the final states energy position in RIXS spectra and we show that DyNi3 has a higher 5d orbital occupancy than Dy25Fe18.

Abstract
The Laser Interferometer Gravitational-Wave Observatory has performed a third science run with much improved sensitivities of all three interferometers. We present an analysis of approximately 200 hours of data acquired during this run, used to search for a stochastic background of gravitational radiation. We place upper bounds on the energy density stored as gravitational radiation for three different spectral power laws. For the flat spectrum, our limit of omega0 < 8.4 x 10(-4) in the 69-156 Hz band is approximately 10(5) times lower than the previous result in this frequency range.

Abstract
We place direct upper limits on the amplitude of gravitational waves from 28 isolated radio pulsars by a coherent multidetector analysis of the data collected during the second science run of the LIGO interferometric detectors. These are the first direct upper limits for 26 of the 28 pulsars. We use coordinated radio observations for the first time to build radio-guided phase templates for the expected gravitational-wave signals. The unprecedented sensitivity of the detectors allows us to set strain upper limits as low as a few times 10(-24). These strain limits translate into limits on the equatorial ellipticities of the pulsars, which are smaller than 10(-5) for the four closest pulsars.
