Abstract
Our previous study demonstrated that T helper (Th) cells from patients with rheumatoid arthritis (RA) display an altered expression profile of Notch receptors and enhanced activation of Notch signalling. The aim of this study was to investigate the role of distinct Notch receptors and ligands in the activation and differentiation of collagen II (CII)-reactive Th cells upon antigen-specific restimulation. Spleen mononuclear cells (SMNCs) from CII-immunized DBA/1J mice were restimulated by culturing with CII. CII-specific proliferation and differentiation of T cells were determined by tritiated thymidine ((3) [H]-TdR) incorporation and flow cytometric analysis, respectively. The mRNA expression of Notch receptors and Hes1 was assessed by real-time polymerase chain reaction (PCR). There was a clear increase in the percentage of Th1 cells and Th17 cells after CII restimulation. No significant difference was observed in the percentage of regulation T cells (T(reg) ) in SMNCs with or without CII restimulation. CII restimulation induced up-regulated transcript levels of Hes1 in CII-reactive CD4(+) T cells. The mRNA level of Notch3 was also up-regulated significantly, while the levels of the other three Notch receptors were not increased. Inhibition of Notch signalling by N-[N-(3,5-difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester (DAPT) and Notch3 antibody decreased the collagen-specific T cell proliferation and attenuated Th1- and Th17-type responses, while treatment with Notch ligand Delta-like 1 promoted such a response. The present study demonstrates that Notch signalling is engaged in CII-specific Th1- and Th17-type expansion in which Notch3 and Delta-like1 were involved. Selective inhibition of Notch signalling mediated by Notch3 or Delta-like1 may offer a new strategy for the treatment of RA.

Abstract
Invasive pulmonary aspergillosis (IPA) has been increasingly frequent in severe liver disease. We aim to investigate the clinical presentation, predisposing factors, and treatment of IPA in patients with liver failure caused by hepatitis B virus (HBV) infection. Medical records from 798 patients with HBV-related liver failure were reviewed. A total of 43 patients with probable IPA were selected as the case group, another 43 patients with bacterial infection and 43 patients without any infections were selected, for whose age, sex, date of admission, and the disease onset were matched with the case group. We evaluated the risk factors, clinical manifestations, treatment, and subsequent outcome of IPA in patients with HBV-related liver failure. Multivariate logistic regression models were used to demonstrate risk factors associated with IPA. Compared with patients with bacterial infection and those without any infection, patients with probable IPA used more antibiotics and steroids, and had poorer conditions and the highest mortality (P < 0.0001). Multiple antibiotics use and frequent invasive procedures were independent factors associated with the occurrence of IPA in patients with HBV-related liver failure. Patients with HBV-related liver failure are predisposed to IPA and may have a more severe condition and poorer prognosis.

Abstract
The pharmacokinetics of lipoyl vildagliptin, a novel dipeptidyl peptidase IV (DPP IV) inhibitor, was studied in rats after oral administration for developing it as an antidiabetic agent. A liquid chromatography-tandem mass spectroscopy (LC-MS/MS) method was developed to determine lipoyl vildagliptin in rat plasma. After an overnight fasting, rats were orally given lipoyl vildagliptin. Following a single oral dose of 25, 50, and 100 mg x kg(-1), T(max) values were from 1.25 to 1.84 h, CL/F values were around 100 l h(-1) kg(-1). In the dose range, C(max) values (63.9-296 μg x l(-1)) and AUC(0-∞)values (260-1214 μg x h x l(-1)) were proportional to the doses. In conclusion, this LC-MS/MS method for the determination of lipoyl vildagliptin in rat plasma was selective and sensitive. In rats, lipoyl vildagliptin displayed linear pharmacokinetics after a single oral dose in the range of 25-100 mg x kg(-1). Lipoyl vildagliptin might have very high CL/F values and V(d)/F values, which indicated that the bioavailability of this drug might be low or lipoyl vildagliptin might distribute extensively or accumulate in tissues in view of its high liposolubility.

Abstract
Recently, it has been reported that a new activation method, brief exposure to cycloheximide before electrical activation, could increase development rates and reduce cell death. In our study, we allocated reconstructed SCNT embryos into 3 groups: electrical activation followed by exposure to cycloheximide (10 μg mL–1) for 4 h (ELE+CHX); exposure to cycloheximide (10 μg mL–1) for 10 min followed by electrical activation (CHX+ELE); and electrical pulse treatment alone (ELE). We found the CHX+ELE (10 min) group had a similar blastocyst formation rate and total blastocyst number with the ELE+CHX (4 h) group, and both groups could increase in vitro development compared with the ELE group. Trichostatin A (TSA), an inhibitor of histone deacetylase, has been reported to potentially enhance cloning efficiency. We examine the effect of TSA on nuclear transfer embryos produced by the CHX+ELE activation method. The reconstructed embryos were treated with 50 nM TSA for 0 and 36 h. We found that 50 nM TSA for 36 h after activation had an increased blastocyst rate compared with the control (15.35 v. 8.84%; P < 0.05), but there was no difference in cleavage rate or in total blastocyst numbers. Our data demonstrate that TSA treatment could significantly improve pig nuclear transfer embryos produced by a new activation method.

Abstract
BACKGROUND Pneumonitis induced by pandemic influenza A H1N1 has a potential to cause respiratory failure, which is a risk factor for death. The underlying immunopathological mechanisms, however, have not yet been fully elucidated. PATIENTS AND METHODS We investigated changes in plasma cytokines, T cell subsets, and C-reactive protein (CRP) in 16 hospitalized patients with pneumonia caused by 2009 H1N1 influenza infection. The patients were classified into a severe disease group and a mild disease group according to PaO2. RESULTS Cytokine profiles showed no changes in interferon gamma (IFN-gamma), interleukin 6 (IL-6), IL-8, or transforming necrosis factor alpha (TNF-alpha) levels throughout the observation period. Transforming growth factor beta (TGF-beta1) was overproduced in the severe group but not in the mild group. Accordingly, we also found some signs of pulmonary fibrosis during the recovery period. Elevated CRP levels and lymphopenia were common in both the severe and the mild group. After treatment, there was a significant elevation in lymphocytes in both groups, but a significant decrease in CRP in the mild group. Lymphocyte counts and CRP levels rapidly recovered to normal levels in all survivors posttreatment; otherwise it seemed to be related to poor prognosis. CONCLUSIONS Serial measurements of cytokines showed that only TGF-beta1 was overproduced, possibly in relation to the early use of corticosteroids, which may have downregulated immune responses to H1N1 infection. Pretreatment TGF-beta1 plasma concentrations and absolute lymphocyte counts were independent predictors of severity. However, the role of elevated TGF-beta1 in H1N1 infection-associated pulmonary fibrosis requires further investigation.

Abstract
Cellulase is the key to utilize the renewable and abundant cellulose resource, cellulase-producing microorganism is an important source of cellulase. The traditional screening method of cellulase-producing microorganism is low efficacy and not macroscopic. The screening method in this study was based on the interactive culture character between cellulase-producing bacteria and Phytophthora parasitica var. nicotianae on plates, the results indicated that the inhibition zone and cellulase activity of bacterial strains are conformity on the whole, so the screening method is very quickly and apparent.

Abstract
We report molecular cytogenetic characterization of mosaic supernumerary r(1)(p13.2q23.3) in a 10-year-old girl with epilepsy, facial asymmetry, psychomotor retardation, kyphoscoliosis, dermatofibrosarcoma and multiple exostoses. The supernumerary r(1) is associated with gene dosage increase of CHRNB2, ADAR and KCNJ10 in the pericentromeric area of 1q, and a breakpoint within CTTNBP2NL at 1p13.2. We speculate that the gene dosage increase of CHRNB2, ADAR and KCNJ10 is most likely responsible for epilepsy, and the breakpoint at 1p13.2 in the supernumerary r(1) is most likely responsible for the development of multiple exostoses and osteochondroma in this patient.

Abstract
OBJECTIVES To understand the advancements in and barriers to the implementation of measures to improve basic public health services in an urban Chinese community. STUDY DESIGN A qualitative study based on semi-structured interviews. Interviews were audio-taped, transcribed and analysed using thematic content analysis. METHODS In-depth interviews were undertaken with the directors of the management centres for community health services in 15 of the 18 districts in Beijing from December 2008 to February 2009. Content analysis of the data was completed in May 2009. RESULTS Fifteen types of free basic public health services had been delivered in Beijing. Some were supplied at a low level. An average of £2.38 per person per year was provided for inhabitants since 2008, but demand for funding far exceeded monies available. Teams consisting of general practitioners, community nurses and public health specialists delivered these services. The number of practitioners and their low levels of skill were insufficient to provide adequate services for community residents. Respondents gave recommendations of how to resolve the above problems. CONCLUSIONS In order to improve the delivery of basic public health services, it is necessary for Beijing Municipal Government to supply clear and detailed protocols, increase funding and increase the number of skilled practitioners in the community health services.
