①Rat MSC and VSMC were cultured and identified, respectively. MSC were labeled with DAPI firstly, and then co-cultivated with VSMC. The changes of morphology and ultrastructure of co-cultured cells were observed. Immunfluorescence analysis was performed by using monoclonal antibodies against specific antigen.②We established the regulatable system in two steps: a stable MSC line expressing rtTA has been constructed and characterized firstly by transfected with pUHD 17-1hyg and then selected by hygromycin B; in a second step, this line was used for trandfer the AT2R gene to MSC to get the well establishing double stable MSC lines;③The expression of AT2R regulated by doxycycline was evaluated by western blot;④The MSCs were transduced into rat carotid arteries with regulatable AT2R gene after the establishment of rat carotid balloon injury restenosis model. The intimal/medial area ratio were measured by digital analysis system.

Results: The main manifestations of imaging in PCCCL appeared as peripheral nodules or masses (6/7) in the right lung. Tiny nodules with coarse spiculate margin, lack of pleural indentation and vacuole sign. When masses of turmor grew larger, smooth margins were found in them. spinous process and cavity were seldom seen. Central mass of left lung superior lobe (n=1), lesion was lobulated, and with smooth margin, which seem others central carcinoma of the lung.
结果:PCCCL影像学上主要表现为右肺周围性肿块或结节(6/7),结节边缘可见毛刺征,无胸膜凹陷征、空泡征;肿块较大时,边缘光滑,无棘状突起、空洞等征象,1例左肺上叶中心性分叶状肿块,边缘光滑,酷似其它类型肺癌。

The essence of EDID is to set up a normal behavior fuzzy sub collection A on the basis of watching the normal system transfer of the privilege process, and set up a fuzzy sub collection B with real time transfer array, then detect with the principle of minimum distance in fuzzy discernmethodThe innovation point of this paper is : Put forward the method of EDID, can not only reduce efficiently false positive rate and false negative rate, also make real time intrusion detection to become possibility; have independent and complete character database, according to the classification of monitoring program, design normal behavior and anomaly behavior etc., have raised the strongness of IDS; Use tree type structure to preservation the character database, have saved greatly stock space; in detection invade , carry out frequency prior principle, prior analysis and handling the behavior feature of high frequency in information table, have raised efficiency and the speed of detection, make real time intrusion detection to become possibility; have at the same time realized anomaly intrusion detection and misuse intrusion detection, have remedied deficiency of unitary detection method.
