B7-H1 and B7-H3, two members of the B7 family that are thought to regulate T-cell activation, are expressed in human non-small cell lung cancer (NSCLC). However, their prognostic significance is poorly understood. In the present study we reported that B7-H1 and B7-H3 were expressed in 96/128 (72.7%) and 89/128 (69.5%) samples, respectively. B7-H1 and B7-H3 expression and the number of infiltrating T-cell intracellular antigen-1+ and interferon-γ + cells in NSCLC tissues were significantly higher than those in the adjacent tissues (p < 0.01). High B7-H1 or B7-H3 expression was associated with lymph node metastasis and TNM stage (p < 0.05, respectively). Sex, TNM stage, B7-H1, B7-H3, and T-cell intracellular antigen-1 expression remained significant prognostic factors after adjusting for other prognostic factors in a multivariate Cox proportional hazards regression model. In vitro studies revealed that knockdown of B7-H3 on tumor cells enhanced T-cell growth and interferon-γ secretion when stimulated by anti-CD3 and anti-CD28 monoclonal antibodies. Interferon-γ reduced CXCR4 expression on cancer cells and inhibited the CXCL12-induced cell migration.B7-H1 and B7-H3 are independent predictors of poorer survival in patients with NSCLC. Interference of the signal pathways of these negative regulatory molecules might be a new strategy for treating NSCLC. Source

Multi-centric solid-pseudopapillary neoplasm (SPN) of the pancreas is a rare tumor: only 4 cases are reported in the literature. The clinical and pathological features have not yet been fully clarified. We report 3 cases of multi-centric SPN and discuss their clinical presentations and histological and immunohistochemical features, comparing with solitary SPN. Among the total of 7 cases, 6 were female and 1 was male. Patients had nonspecific symptoms at presentation. Tumors were often large and well demarcated with cystic degeneration and clear margin between lumps. Histologically, characteristic pseudopapilla was formed with uniform cells surrounding the delicate blood vessels. Tumor cells were positive for vimentin, synaptophysin, progesterone receptor, and CD10 and demonstrated nuclear localization of β-catenin. The prognosis of patients was excellent after complete surgical resections. Multi-centric SPN shares similar clinical and pathological features to solitary SPN. © 2012 Springer Science+Business Media New York. Source

Objective: To observe the clinical efficacy of combined tuina and Chinese medicinal fumigation for knee osteoarthritis. Methods: The 147 cases were randomly allocated into a treatment group of 76 cases and a control group of 71 cases. Combined tuina and fumigation were employed in the treatment group, versus combined oral Gu Ci Ning capsule and external application of plasters in the control group. The therapeutic effect was observed after 2 courses of treatment. Results: The total effective rate of the treatment group was 98.7%, versus 84.5% in the control group, indicating a significant difference (P<0.01). Conclusion: Combined tuina and Chinese medicinal fumigation has exact effect for knee osteoarthritis. © 2011 Shanghai Research Institute of Acupuncture and Meridian and Springer-Verlag Berlin Heidelberg.

We performed our study to determine whether plasma macrophage migration inhibitory factor (MIF) levels have diagnostic and prognostic value in hepatocellular carcinoma (HCC) patients. Enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry were used to measure the expression of MIF in plasma and tissues, respectively. Plasma MIF levels were compared to HCC occurrence, clinicopathological features and outcomes. Cutpoints of plasma MIF levels for diagnosis and prognosis were, respectively, determined by receiver operating characteristic analysis and X-tile in corresponding training cohort, and then were confirmed in the validation cohort. The postoperative plasma MIF levels of HCC patients were detected in an independent cohort (80 HCC patients). As a result, MIF expression in situ was mainly observed in the cytoplasm of HCC cells. Intratumoral MIF expression was positively correlated with plasma MIF levels (r = 0.759, p < 0.001). Compared to serum α-fetoprotein (AFP), plasma MIF had a higher diagnostic value for discrimination of HCC from controls at 35.3 ng/ml. With determined cutpoints, plasma MIF levels demonstrated a significant association with overall survival (OS) and disease-free survival (DFS) of HCC patients even in patients with normal serum AFP levels and Tumor Node Metastasis (TNM) stage I. In addition, the plasma MIF levels were identified as an independent factor for OS [hazard ratio (HR) = 1.754; p = 0.012] and DFS (HR = 2.121; p < 0.001). Plasma MIF levels decreased markedly within 30 days after tumor resection (p < 0.001). Therefore, plasma MIF levels have potential as a diagnostic and prognostic factor for HCC.

Allostery is the most direct, rapid and efficient way of regulating protein function, ranging from the control of metabolic mechanisms to signaltransduction pathways. However, an enormous amount of unsystematic allostery information has deterred scientists who could benefit from this field. Here, we present the AlloSteric Database (ASD), the first online database that provides a central resource for the display, search and analysis of structure, function and related annotation for allosteric molecules. Currently, ASD contains 336 allosteric proteins from 101 species and 8095 modulators in three categories (activators, inhibitors and regulators). Proteins are annotated with a detailed description of allostery, biological process and related diseases, and modulators with binding affinity, physicochemical properties and therapeutic area. Integrating the information of allosteric proteins in ASD should allow for the identification of specific allosteric sites of a given subtype among proteins of the same family that can potentially serve as ideal targets for experimental validation. In addition, modulators curated in ASD can be used to investigate potent allosteric targets for the query compound, and also help chemists to implement structure modifications for novel allosteric drug design. Therefore, ASD could be a platform and a starting point for biologists and medicinal chemists for furthering allosteric research.
