Differences between Hodgkin's lymphoma (HL) patients in China and Western countries are known to exist, but data on Chinese patients with HL are limited. It is not clear whether there are clinical and histological differences in patients with HL involving different extranodal sites. This is the first study to analyze Chinese patients with HL involving different extranodal sites. We selected 22 HL patients with extranodal involvement from more than 250 previously untreated HL patients. Most patients were young males, and 20 of the 22 patients had stage IV disease. The major pathologic types were nodular sclerosis classical HL (NSCHL) and mixed cellularity classical HL(MCCHL). At diagnosis, the most commonly involved extranodal sites were the liver and lung, followed by the bones. There was no significant association between the international prognostic score(ips) and survival in patients with different extranodal sites. Our data showed the overall survival (OS) and disease-free survival (DFS) rates of low-risk group (ips = 0-2) were relatively higher than those of high-risk group (ips ≥ 3), but the ips did not show predictive power for survival. Although HL with extranodal involvement is rare, it should be considered as a unique form of HL.

Induced pluripotent stem (ips) cell technology demonstrates that somatic cells can be reprogrammed to a pluripotent state by over-expressing four reprogramming factors.This technology has created an interest in deriving ips cells from domesticated animals such as pigs,sheep and cattle.Moloney murine leukemia retrovirus vectors have been widely used to generate and study mouse ips cells.However,this retrovirus system infects only mouse and rat cells,which limits its use in establishing ips cells from other mammals.In our study,we demonstrate a novel retrovirus strategy to efficiently generate porcine ips cells from embryonic fibroblasts.We transfected four human reprogramming factors (Oct4,Sox2,Klf4 and Myc) into fibroblasts in one step by using a VSV-G envelope-coated pantropic retrovirus that was easily packaged by GP2-293 cells.We established six embryonic stem (ES)-like cell lines in human ES cell medium supplemented with bFGF.Colonies showed a similar morphology to human ES cells with a high nuclei-cytoplasm ratio and phase-bright flat colonies.Porcine ips cells could form embryoid bodies in vitro and differentiate into the three germ layers in vivo by forming teratomas in immunodeficient mice.

As a milestone breakthrough of stem cell and regenerative medicine in recent years,somatic cell reprogramming has opened up new applications of regenerative medicine by breaking through the ethical shackles of embryonic stem cells.However,induced pluripotent stem(ips) cells are prepared with a complicated protocol that results in a low reprogramming rate.To obtain differentiated target cells,ips cells and embryonic stem cells still need to be induced using step-by-step procedures.The safety of induced target cells from ips cells is currently a further concerning matter.More broadly conceived is lineage reprogramming that has been investigated since 1987.Adult stem cell plasticity,which triggered interest in stem cell research at the end of the last century,can also be included in the scope of lineage reprogramming.With the promotion of ips cell research,lineage reprogramming is now considered as one of the most promising fields in regenerative medicine,will hopefully lead to customized,personalized therapeutic options for patients in the future.

The integrated power system(ips) is a foundation of all-electrical ships and vessels. The stability of ips becomes a prerequisite of complicated cruise tasks. Thus, advanced stability analysis and regulation methods for ips are of great importance. In this paper, a novel method is proposed for analyzing and enhancing transient stability of ips, which is regarded as a cyber-physical system comprising of subsystems and connections. Criterions for determining input-output stability of such a system are firstly derived. Then, the stability analysis of ips can be performed in the following two steps: 1) evaluating local input-output stability features of each subsystem independently through simulations. 2) Checking stability criterions with system topology and subsystem stability features. Moreover, synthetic approaches are proposed for stabilization and stability enhancement of ips. To avoid system in-stability after major failures or topology changes, the optimal emergency control is performed to reconfigure subsystems. The other optimal regulation is used to strengthen system stability by adjusting subsystems' control parameters during normal operation conditions. Case studies on a typical ips validate the proposed stability analysis and enhancement approach.

Previous research has shown that mouse embryonic stem (ES) cells can be induced to form neural cells in adherent monocultures.In this study,pluripotent stem (ips) C5 cells derived from meningeal membranes were converted successfully into neural-like cells using the same protocol generally used for ES cells.Meningeal-ips C5 cells were induced to express neural markers Sox1,Sox3,Pax6,Nestin and Tuj1 and to reduce the expression of ES markers Oct4 and Nanog during neural differentiation,and can be differentiated into Pax6 and Nestin positive neural progenitors,and further into neuronal,astrocytic,and oligodendrocytic cells.In vitro differentiation of ips cells into patient-specific neural cells could serve as a model to study mechanisms of genetic diseases and develop promising candidates for therapeutic applications in dysfunctional or aging neural tissues.Meningeal cells express a high level of the embryonic master regulator Sox2,allowing them to be reprogrammed into ips cells more easily than other somatic cells.

A so-called ISF method for predicting geomagnetic disturbances caused by solar wind storm blowing to the earth is suggested. The method is based on a combined approach to solar activity, interplanetary scintillation (ips) and geomagnetic disturbance observations in 1966-1982, dynamics of disturbance propagation and fuzzy mathematics. Prediction test has been made for 24 large geomagnetic disturbance events that produced space disasters during the period of 1980-1998, with the three-dimensional propagation characteristics, the best close degree of each radio source and the influence of the south-north components of interplanetary magnetic fields considered. The main results are (I) for onset time of the geomagnetic disturbance, events with relative error △Tpred/Tobs≤10% between the observation Tobs and the prediction Tpred, account for 45.8% of all events, ≤30% for 78.3% and >30% for only 21.7%; (ii) as for the magnetic disturbance magnitude, events with relative error △∑Kp,pred/∑Kp,obs≤10% between the observation ∑Kp,obs and the prediction ∑Kp,pred, account for 41.6% of all events, ≤30% for 79% and ≤45% for 100%. For example, the prediction test of April-May event in 1998 indicates that △Tpred/Tobs=7.4%, △∑Kp,pred/∑Kp,obs=15.3%. Our result shows that the prediction method suggested in this paper has encouraging prospects in improving geomagnetic disturbance prediction in space weather events.
