Abstract
We describe a case-control study performed in Jiangsu, China, to evaluate risk factors for human infection with novel avian influenza A(H7N9) virus. Twenty-five cases and 93 controls matched by age, sex, and location were included in the study. Direct contact with poultry or birds in the two weeks before illness onset, chronic medical conditions (hypertension excluded), and environment-related exposures were significantly associated with A(H7N9) infection.

Abstract
Several studies by microarray analysis and real-time polymerase chain reaction (RT-PCR) reveal that type I interferon-inducible genes (IFIGs) are implicated in systemic lupus erythematosus (SLE). To find a potential clinical biomarker capable of monitoring lupus disease activity clinically, quantitative RT-PCR was used to identify transcript expression levels of 13 type I IFIGs in peripheral blood cells in 144 patients with SLE, 27 non-SLE patients and 60 healthy controls and then analyse connections between gene expression and disease activity. The expression levels of five type I IFIGs (LY6E, OAS3, IFIT4, OAS1 and OAS2) were significantly higher in the SLE group than in the healthy and non-SLE controls. LY6E gene that had highest expression was chosen to analyse the association of expression level with clinical features. Compared to low LY6E expression group, SLE patients with high LY6E expression had higher SLEDAI-2K score, increased 24 h urine protein and lower blood C3 complement. Active SLE patients had more elevated LY6E expression than stable patients. And LY6E expression levels in patients with SLE were strongly correlated with their SLEDAI-2K scores. Our results indicate that increased expression of LY6E gene in peripheral blood cells in patients with SLE is correlated with lupus activity and may be a useful, noninvasive biomarker for assessing SLE disease activity.

Abstract
BACKGROUND Tumor necrosis factor-alpha (TNF-alpha) is a multifunctional cytokine that has cytotoxic, cytostatic and immunomodulatory effects on malignant tumors. However, clinical trials have revealed high systemic toxicity and this has hampered its utilization as an anti-cancer agent. In this study, a human TNF-alpha mutant was created and tested for its anti-tumor effects. METHODS The TNF mutant (recombinant mutated human TNF; rmhTNF) was prepared by protein engineering in which amino acids Pro, Ser and Asp at positions 8, 9 and 10 of TNF-alpha were substituted by Arg, Lys and Arg, and C terminal Leu157 was substituted by Phe, along with deletion of the first seven N-terminal amino acids. Prokaryotic expression recombinant vector pBV-mhTNF containing the PLPR promotor was constructed and transformed into E. coli DH5alpha. The rmhTNF was expressed in a partially soluble form in DH5alpha, purified from the supernatant of cell lysate by ammonia sulfate precipitation and two sequential chromatographic steps. RESULTS The purified rmhTNF was >95% pure by SDS-PAGE stained with silver and high-pressure size exclusion chromatography (SEC-HPLC). Its yield was about 1.22 mg/g wet cell paste. The mutant rmhTNF exhibited an approximately 50-fold increase in cytotoxicity relative to the wild-type rhTNF on the mouse fibroblast cell line L929 in a standard cytotoxicity test, and at least and at least 50 times higher LD50 as wild type rhTNF in mice. In vivo biological activity studies carried out on tumor cell transplanted mice and nude mice also showed a more effective cytotoxicity of rmhTNF than rhTNF. DISCUSSION These results suggest that rmhTNF has potential for developing an effective anti-tumor reagent for some tumors.

Abstract
We present a case of Sturge-Weber syndrome with a bilateral lymphatic/venous malformation of the mandible. Modern biology suggests an explanation for such a case. The classification of cerebrofacial venous metameric syndromes (CVMS) enables us to recognise this lesion as involving the most caudal of the cranial metamere (CVMS 3).

Abstract
Activated macrophages play a central role in antitumor immunity. However, the stimuli that activate macrophages to kill tumor cells are not completely understood. Because the center of solid tumors can be hypoxic, we hypothesized that hypoxia may be an important signal in activating macrophages to kill tumor cells. Hypoxia stimulates IFN-primed macrophages to express the inducible nitric oxide synthase (NOS2) and to synthesize nitric oxide (NO). We show that this synergy between IFN and hypoxia is mediated by the direct interaction of the hypoxia inducible factor-1 (HIF-1) and IFN regulatory factor-1 (IRF-1), which are both required for the hypoxic transcription of NOS2. This interaction between HIF-1 and IRF-1 may explain the mechanism by which macrophages infiltrating into tumors are activated to express NOS2 and to produce NO, a mediator of tumor apoptosis.

Abstract
Pulmonary inflammation and fibrosis are characterized by increased turnover and production of the extracellular matrix as well as an impairment of lung fibrinolytic activity. Although fragments of the extracellular matrix component hyaluronan induce macrophage production of inflammatory mediators, the effect of hyaluronan on the fibrinolytic mediators plasminogen activator inhibitor (PAI)-1 and urokinase-type plasminogen activator (uPA) is unknown. This study demonstrates that hyaluronan fragments augment steady-state mRNA, protein, and inhibitory activity of PAI-1 as well as diminish the baseline levels of uPA mRNA and inhibit uPA activity in an alveolar macrophage cell line. Hyaluronan fragments alter macrophage expression of PAI-1 and uPA at the level of gene transcription. Similarly, hyaluronan fragments augment PAI-1 and diminish uPA mRNA levels in freshly isolated inflammatory alveolar macrophages from bleomycin-treated rats. These data suggest that hyaluronan fragments influence alveolar macrophage expression of PAI-1 and uPA and may be a mechanism for regulating fibrinolytic activity during lung inflammation.

Abstract
OBJECTIVE To investigate the imbalance of Th1/Th2-type cytokines in patients with systemic lupus erythematosus (SLE) and its relation to disease activity. METHODS Intracellular cytokines were determined by flow-cytometry following whole-blood culture. RESULTS Patients with systemic lupus erythematosus disease activity index (SLEDAI) > 10 had statistically significantly fewer CD4+ or CD8+ T cells producing IFN-gamma than patients with SLEDAI = 0, SLEDAI 1-10 or healthy controls (P < 0.01, P < 0.01 or P < 0.05, respectively). Patients with SLEDAI > 10 also had decreased ratio of IFN-gamma/IL-4 positive CD4+ or CD8+ T cells, compared with patients with SLEDAI = 0, SLEDAI 1-10 or healthy controls (P < 0.05). The decreased Th1 or Tc1 cells and the ratios of IFN-gamma: IL-4 positive CD4+ T-cells were significantly correlated with disease activity (P < 0.05). CONCLUSION SLE is characterized by an imbalance of Th1/Th2 and Tc1/Tc2 cytokines. The decreased Th1 or Tc1 cells and the Th1/Th2 ratio are related to disease activity.

Abstract
OBJECTIVE To evaluate the effects of PHB membrane around dental titanium implants used in guided bone regeneration technique. METHODS Endosseous cylindrical implants were placed in dogs' mandibles after extraction of all the mandibular premolars and the first molars immediately. Ideal implant placement sites were modified by creating standardized 3 mm x 5 mm facial dehiscent defects. The defects were covered with PHB membrane and titanium membrane respectively, then the membranes were fixed on the periosteum by sutures, and the remainder served as controls. Tissue closure was achieved with mattress and interrupted single sutures, and antibiotic injection was given to the dogs in the following 3 days. The dogs were divided into three groups according to the healing time of 1, 2 and 3 months, then the three groups of dogs were sacrificed. After that, tissue blocks containing the implants and the control ones were removed and studied by gross observation, X-ray radiograph and fluorescence microscope, and the surfaces of the membranes were observed by scanning electron microscope. The specimen used for light microscope study were fixed with 10% formaldehyde for 24 hours, and decalcified with 0.5 mol/L EDTA for 2 weeks. After the titanium implants were carefully removed, the tissue blocks were embedded into the paraffin wax, and the sections were obtained. RESULTS The PHB membrane degraded slowly and partly 3 months after placement, and the biodegradable property of the PHB membrane deserved a longer period of study; The bone defects covered with PHB and titanium membrane were filled with much more new bone than that of the control group. CONCLUSION PHB membrane can enhance bone formation and can be used for guided bone regeneration.

Abstract
OBJECTIVE To explore whether patients with ankylosing spondylitis (AS) have hearing loss and the pattern of hearing loss. METHODS Questionnaire, physical examination of the ear, nose and throat, hearing test and sero-immunity examinations were conducted in 34 patients (68 ears) with AS. RESULTS Among 34 patients, 11 cases reported decrease in the sound perception, and 24 cases (41 ears, 60.3%) had hearing loss as evidenced by the pure tone audiometry. In those patients with hearing loss, 2 ears with perforation of tympanic membrane showed conductive hearing loss and the remainder 39 ears showed sensorineural hearing loss in which 26 ears (66.7%) experienced high frequency hearing loss. Auditory brainstem responses were normally presented in 26 case, whereas abolished in 1 case (2 ears) with severe hearing loss. Examinations of sero-immunity showed a positive response in HLA-B27, but negative responses in the antinuclear antibody and rheumatoid factor. The percentage of the C-reactive protein increase was 81.8%. Autoantibodies anaginst the inner ear were positive in 9 cases (28.1%). In addition, all other immunological examinations revealed certain changes. CONCLUSION More than half of the patients with AS had sensorineural hearing loss, particularly in the high frequency range. This hearing loss is paralleled by abnormal immunology and is a local expression of systemic autoimmune disease. Therefore, periodical hearing tests are necessary for these patients.

Abstract
Coxsackievirus infection causes myocarditis and pancreatitis in humans. In certain strains of mice, Coxsackievirus causes a severe pancreatitis. We explored the role of NO in the host immune response to viral pancreatitis. Coxsackievirus replicates to higher titers in mice lacking NO synthase 2 (NOS2) than in wild-type mice, with particularly high viral titers and viral RNA levels in the pancreas. Mice lacking NOS have a severe, necrotizing pancreatitis, with elevated pancreatic enzymes in the blood and necrotic acinar cells. Lack of NOS2 leads to a rapid increase in the mortality of infected mice. Thus, NOS2 is a critical component in the immune response to Coxsackievirus infection.
