In permafrost regions with warm frozen soil,subgrade thaw-collapse phenomenon commonly occurs,facing thaw collapse problems of the existed frozen soil subgrade,thus it is difficult to use traditional methods such as active cooling and passive protection technology to stabilize the existed warm frozen soil *** study derives a novel stabilizer method,a long-short(L-S)cement-mixed batter pile composite foundation to stabilize the existed warm frozen soil *** solve the thawcollapse problems in warm frozen soil subgrade,high water content and large compressibility characteristics were compared between soft soil and warm frozen *** analysis of heat conduction and numerical simulation of finite element model were used to study the freeze–thaw process and evaluate the stabilized effects of the L-S cement-mixed batter piles on the warm frozen soil foundation of the qinghai-Tibet ***,the thaw process and mechanical properties of foundation and piles were analyzed by introducing the hydration heat factor in the thermodynamic control *** results indicate that the thawing displacement of the existed warm frozen soil subgrade was reduced owing to the“support”and“grasp”effects of the L-S cement-mixed batter piles on the surrounding *** composite ground formed by strengthening the warm frozen ground with batter piles could considerably improve the bearing capacity of the existed warm frozen ground,effectively restrain the deformation of the upper embankment,and improve the strength of the *** analysis can provide method for the construction design of cement mixing batter pile foundation in cold regions.

Aplastic anemia （AA）, myelodysplastic syndrome （MDS）, and paroxysmal noctumal hemoglobinuria （PNH） are bone marrow failure disorders closely related to each other. PNH often occurs in the course of AA or MDS-refractory anemia （RA）. Acquired AA patients, particularly with PNH clones, have benefited from the immunosuppressive therapy （IST）. Although the possible immune abnormality was not considered as the core mechanism in MDS pathology,1 MDS-RA cases with PNH clones also reflected a high probability of response to IST. We report here one rare case of advanced MDS with PNH clones diagnosed by flow cytometry （FCM）.

Qualitative reasoning uses incomplete knowledge to compute a description of the possible behaviors for dynamic systems. A standard qualitative simulation（QSIM） algorithm frequently results in a large number of incomprehensible behavioral descriptions and the simulation for complex systems frequently is intractable. Two model de- composition methods are proposed in this paper to eliminate or decrease the insujficiency of this algorithm. Using a directed graph to represent the qualitative model, the strongly connected graph based theory and genetic algorithm based model decomposition are proposed to decompose the model. A new simple system model is reconstructed by subgraphs and causal relations when the system directed graph is decomposed completely. Each sub-graph is viewed as a separate system and will be simulated separately, and the simulation result of causally upstream subsystem is used to constrain the behavior of downstream subsystems. The model decomposition algorithm provides a promising paradigm for qualitative simulation whose complexity is driven by the complexity of the problem specification rather than the inference mechanism used.

AIM: The imaging features of MRI and DSA, using the modelsof implanted and induced hepatoma, were investigated in ***: CBRH3 cancer cells were implanted for differentliver site of rat liver and the diethylnitrosoamine was givenorally to rats in order to induce liver cancer. Both experimentalgroups were detected by magnetic resonance imaging (MRI),digital subtraction angiography (DSA) and morphologic ***: Hypointensity on T1WI and homogenous highsignal intensity on T2WI in MRI, and ring-like abnormal stainon DSA were found in implanted cancer. Induced cancersappeared as homogeneous or heterogeneous hypointensityon T1WI (10 cases), and equal or slight high intensity onT2WI (8 cases), but some as hypointensity on T2WI (2 cases).CONCLUSION: The imaging features of implanted cancerswere similar to that of human liver metastases. Therefore, itcould serve as an experimental model of human liver metastatictumor. The imaging feature of induced cancers, whereas, weresimilar to that of human primary liver cancer. It could be useas an experimental model of human primary liver cancer.
