To study characteristics and market structure of data service and the role ofoperator, this paper makes a commercial model by applying the theory of intermediaries andneoclassic economics. Data service has different economic characteristics from voice ***, production mode of data service is roundabout production, secondly, driving power of dataservice is economies of specialization, and finally, management method of data service is impersonalmanagement. In data service market, information asymmetry and barrier to entry determinetransaction efficiency and the specialization level of service providers indirectly. Therefore,operator should intervene in the market by offering trade service in order to promote development ofservice providers. Because of different quality of service providers, market structure of dataservice must be the state that trade platform built by operator and intermediary platform built byoperator coexists.

Transplantable experimental tumor models were constructed to study the activities of recombinant human interleukin-15 （rhIL-15） against tumor recurrence and metastasis. The results showed that tumor nodule formation was retarded and tumor growth was inhibited in the subcutaneous tumor model of LA795 lung adenocarcinoma after treatment with rhIL-15, and the survival rate of T739 tumor-bearing mice treated with rhIL-15 was much higher than that of mice treated with either saline or with the same dose of rhIL-2. This indicats that rhIL-15 had better antitumor effect than rhIL-2 at the same dose level. In some rhIL-15 treated mice, the tumor cells inoculated subcutaneously were eradicated and there was no tumor formation even 138 days after tumor cell inoculation. The tumor-free mice were rechallenged with live tumor cells and no tumor reoccurred in the following two months in all of these mice, indicating that long-lasting antitumor systemic immunity developed. It was also shown that tumor recurrence and metastasis were inhibited markedly after treatment with rhIL-15, but not with the same dose of rhIL-2, in both subcutaneously and intravenously disseminated tumor models of LA795 lung adenocarcinoma. Simultaneously, the CTL and NK cell activities of the splenocytes obtained from tumor-bearing mice that had been treated with either rhIL-15 or rhIL-2 were both markedly enhanced. However, the enhancement of CTL and NK cell activities was more significant in rhIL-15 treated mice than that in rhIL-2 treated mice. This suggests that the anti-tumor effect of rhIL-15 in vivo was achieved by enhancing the CTL and NK cell activities in tumor immune response.

The goal of the present study is to elucidate the intragastrointestinal fate of micellar delivery systems by monitoring fluorescently labeled different micelles and the model drug paclitaxel(PTX).Both in vitro and ex vivo leakage studies showed fast PTX release in fluids while micelles remained intact,except in fedstate simulated intestinal fluid and fasted-state pig intestinal fluid,thus referring to the intact absorption of micelles and PTX leakage in the gastrointestinal tract with D-a-tocopherol polyethylene glycol 1000 succinate(TPGS)micelles showing higher stability than other *** groups of micelles were absorbed intact in Caco-2 and Caco-2/HT29-MTX cell models and the absorption of TPGS micelles was found to be higher than other *** transport of the micelles across Caco-2/Raji(1.6%-3.5%),Caco-2(0.8%-1%),and Caco-2/HT29-MTX(0.58%-1%)cell monolayers further verified the absorption of micelles and their subsequent transport;however,more TPGS micelles transported across cell monolayers than other ***,the histological examination also confirmed that micelles ente red the enterocytes and were transported to basolateral tissues and TPGS showed the stronger ability of penetration than other ***,these results are succinctly presenting the absorption of intact micelles in GIT confirmed by imaging evidence with prior leakage of the drug,upta ke by enterocytes and the transport of micelles that survive the digestion by enterocytes and mainly by microfold cells in material nature dependent way with TPGS showing better results than other *** conclusion,these results identify the mechanism by which the gastrointestinal tract processes micelles and point to the likely use of this approach in the design of micelles-based therapies.

The measurement-result-conditioned evolution of a system(e.g., an atom) with spontaneous emissions of photons is described by the quantum trajectory(QT) theory. In this work we generalize the associated QT theory from an infinitely wide bandwidth Markovian environment to the finite bandwidth non-Markovian environment. In particular, we generalize the treatment for an arbitrary spectrum, which is not restricted by the specific Lorentzian case. We rigorously prove the general existence of a perfect scaling behavior jointly defined by the bandwidth of the environment and the time interval between successive photon *** a couple of examples, we obtain analytic results to facilitate the QT simulations based on the Monte-Carlo algorithm. For the case where the analytical result is not available, a numerical scheme is proposed for practical simulations.
