Aim: To analyze the significance of different clinical factors for prognostic prediction in diffuse large B-cell lymphoma (DLBCL) patients. Methods: Two hundred and twenty-seven DLBCL patients were retrospectively reviewed. Patients were managed with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen or rituximab plus the CHOP (RCHOP) regimen. Results: Lactate dehydrogenase (LDH), ${\beta}2$-microglobulin (${\beta}2$-M), B symptoms, Ann Arbor stage and genetic subtypes were statistically relevant in predicting the prognosis of the overall survival (OS). In the CHOP group, the OS in patients with germinal center B-cell-like (GCB)(76.2%) was significantly higher than that of the non-GCB group (51.9%, P=0.032). With RCHOP management, there was no statistical difference in OS between the GCB (88.4%) and non-GCB groups (81.9%, P=0.288). Conclusion: Elevated LDH and ${\beta}2$-M levels, positive B symptoms, Ann Arbor stage III/IV, and primary nodal lymphoma indicate an unfavorable prognosis of DLBCL patients. Patients with GCB-like DLBCL have a better prognosis than those with non-GCB when treated with the CHOP regimen. The RCHOP treatment with the addition of rituximab can improve the prognosis of patients with DLBCL.

The goals of this study were to investigate the role of the Notch1/PDGFRβ/ROCK1 signaling pathway in the pathogenesis of pulmonary fibrosis and to explore the possibility of treating fibrosis by targeting Notch1. Lung tissues from patients with pulmonary fibrosis were examined for the expression of Notch1/PDGFRβ/ROCK1 using RT-qPCR, western blotting, and immunostaining. Cultured mouse lung pericytes were transfected with Notch1-overexpressed vectors or shRNA targeting PDGFRβ/ROCK1 to examine cell behaviors, including proliferation, cell cycle arrest, and differentiation toward myofibroblasts. Finally, a mouse pulmonary fibrosis model was prepared, and a Notch1 inhibitor was administered to observe tissue morphology and pericyte cell behaviors. Human pulmonary fibrotic tissues presented with overexpression of Notch1, PDGFRβ, and ROCK1, in addition to a prominent transition of pericytes into myofibroblasts. In cultured mouse lung pericytes, overexpression of Notch1 led to the accelerated proliferation and differentiation of cells, and it also increased the expression of the PDGFRβ and ROCK1 proteins. The knockdown of PDGFRβ/ROCK1 in pericytes remarkably suppressed pericyte proliferation and differentiation. As further substantiation, the administration of a Notch1 inhibitor in a mouse model of lung fibrosis inhibited the PDGFRβ/ROCK1 pathway, suppressed pericyte proliferation and differentiation, and alleviated the severity of fibrosis. Our results showed that the Notch1 signaling pathway was aberrantly activated in pulmonary fibrosis, and this pathway may facilitate disease progression via mediating pericyte proliferation and differentiation. The inhibition of the Notch1 pathway may provide one promising treatment strategy for pulmonary fibrosis.

Salinity stress is a major limiting factor in agriculture and adversely affecting the whole plant. As a halophyte, the moss Physcomitrella patens, has been suggested to be an ideal model plant to study salinity tolerance and adaption. Two abiotic stress-responsive Group 3 Late Embryogenesis Abundant protein genes had been identified in P. patens and named as PpLEA3-1 and PpLEA3-2, respectively. Functions of these two genes were analyzed by heterologous expressions in Arabidopsis, driven either by their native P. patens promoters or by the 35S CaMV constitutive promoter. Phenotype analysis revealed that pLEA3::LEA3, pLEA3::LEA3::GFP and 35S::LEA3::GFP transgenic lines had stronger salinity resistance than that in the wild type and empty-vector control. Further analysis showed that the contents of proline and soluble sugar were increased and the malondialdehyde (MDA) were repressed in these transgenic plants after exposure to salinity stress. Our observations indicate that these two Group 3 PpLEA genes played a role in the adaption to salinity stress.

Access control is the basic of information security. It is always used to protect sensitive information and critical resources from malicious attacks. But the traditional access control models are more adapt to closed network environment. And there are more and more unknown threats and attacks in the open networks, especially the mobile networks. To solve this problem, we propose a new access control model which is applicable to the open mobile networks by using non-zero-sum game theory in this paper. The model is composed by six modules: access evaluation module, access permission determination module, non-zero-sum game theory analysis module, decision-making module, result evaluation module, access feedback module and a prior information database. And in this model, the subjects will choose to be more honest when they make access requests because they all want to get more permission next time. Then we do some experiments to prove this fact.

Purpose: Complement receptor 1 (CR1) is induced by Epstein-Barr virus (EBV) and may be a potential biomarker of nasopharyngeal carcinoma (NPC). We conducted the present study to evaluate the association of CR1 expression with clinicopathological features and prognosis of NPC. Methods: We enrolled 145 NPC patients and 110 controls. Expression levels of CR1 in peripheral blood mononuclear cells (PBMCs) were detected using quantitative real-time PCR and associations with clinicopathological features and prognosis were examined. Results: CR1 levels in the NPC group [3.54 (3.34, 3.79)] were slightly higher than those in the controls [3.33 (3.20, 3.47)] (P<0.001). Increased CR1 expression was associated with histology classification (type III vs. type II, P=0.002), advanced clinical stage (P=0.003), high T stage (P=0.017), and poor overall survival (HR, 4.89; 95% CI, 1.23-19.42; P=0.024). However, there were no statistically significant differences in CR1 expression among N or M stages. Conclusion: These findings indicate that CR1 expression in PBMCs may be a new biomarker for prognosis of NPC and a potential therapeutic target.

Based on the exact analytical method, this paper calculates the no-load back electromotive force, air gap fux density, cogging torque, and electromagnetic torque of outer rotor wheel-hub permanent magnet synchronous motor (PMSM); the calculation results are in good agreement with those of the fnite element method, which verifes the accuracy of the exact analytical method for solving the outer rotor PMSM. On this basis, the second-generation non-dominated sorting genetic algorithm (NSGA-II) is applied to optimize the multiple structural parameters and performance of the motor more quickly. Compared with the initial scheme of the motor, the torque ripple and permanent magnet mass of the optimized scheme is decreased by a quarter; the average electromagnetic torque, efciency is also improved. Finally, the simulation and experimental results show that the proposed method is reasonable and efective.
