The tandem queueing system is a basic structure of queueing networks. However, it is hard to accurately calculate the mean waiting time of the general tandem queueing system except for the tandem queues with the Markov property or constant service times. To characterize the dependence among stations in the tandem queues, this paper proposes the concept of performance ratio to study the mean waiting time. By analyzing the numerical properties of performance ratio, the fitting function of the performance ratio is achieved with which the mean waiting time of the downward station in the tandem queue is approximated. As a result, numerical experiments show that the approximation method based on the performance ratio performs well. [ABSTRACT FROM AUTHOR]

Heptamethine cyanine near infrared fluorescence (NIRF) dyes can be taken up directly and accumulated specifically in the cancer cells and character with tumors target. By conjugated these dye with drug as carriers for the safe delivery of chemotherapies to tumor site through blood-brain barrier (BBB), not only reduce the side effects and doses of drug but also allow the real-time monitoring of therapeutic effect. Moreover theses dyes can be utilized as effective agent for photodynamic therapy. Some these dyes even reveal remarkable tumoricidal activity with mitochondrial toxicity to directly kill tumor cells and inhibit tumor growth by destroying neovascularization. Encapsulated nanoparticle significantly enhanced NIRF dyes tumor-targeting ability and tracking drug release. The different uptake of the dyes into cancer but not normal cells is possible due to the presence of specific organic anion-transporting peptides (OATPs), and regulated by hypoxia and mitochondrial membrane potentials. These advances have widely extended current application of cancer target therapy by NIRF delivery carrier. [ABSTRACT FROM AUTHOR]

Effective preclinical evaluation of the efficacy and safety of antitumor drugs is largely limited by the experimental use of cell line-derived tumor xenografts(CDX) which are deficient in the characteristics of tumor heterogeneity and genetic diversity as compared to primary tumors. As such, the overuse of drugs often fails to treat diseases and the development of clinical drugs is significantly impeded. Patient-derived tumor xenografts(PDTX) inherit intact molecular, genetic and pathologic features from primary tumors, which are sustainable through serial passaging in mice, and thus provide a better alternative model than CDX for developing personalized antitumor therapy. In this review, the characteristics of PDTX model and its applications in cancer research will be summarized. [ABSTRACT FROM AUTHOR]

Objective To assess the effects of surgical clipping for patients with ruptured intracranial aneurysm.

Objective To establish the experimental model of morphine dependent rhesus monkey and observe the changes of D3R expression in nucleus accumbens, hippocampus, cingulate gyrus and cortex of frontal lobe. Methods Four rhesus monkeys were divided into three groups: treatment group (Group A with two monkey), control group (Group B with one monkey) and normal group (Group C with one monkey). The model of morphine dependent monkey was established with imitated Seveers' method and treated by gamma-knife. The changes of D3R expression in nucleus accumbens, hippocampus，cingulate gyrus and cortex of frontal lobe of three groups were observed using immunohistochemistry. Results The D3R expression in Group B was higher than that in Group C ( < 0.001), and the expression density increased range from 254% to 499%. The D3R expression in Group A was lower than that in Group B (< 0.001), but higher than that in Group C. The D3R expression in the nucleus accumbens， hippocampus and cingulategyurs decreased significantly and the expression in nucleus accumbens approached normal after gamma-knife treatment. Conclusion The expression of D3R in the nucleus accumbens significantly decreased after gamma-knife treatment，suggesting D3R is effective to adjust the process of morphine addiction.

Objective To explore the value of ultrasound elastography in the non-invasive monitoring of liver elasticity of stable recipients at different stages after liver transplantation. Methods Clinical data of 73 stable recipients after liver transplantation were collected. According to the time after liver transplantation, all patients were divided into the early group (n=25) and medium-to-long group (n=48). In addition, 38 healthy subjects were assigned into the control group. The ultrasound indexes and liver function indexes were statistically compared among each group. The ultrasound elastography indexes of liver and spleen were analyzed, and their correlation with liver function indexes was analyzed. Results Compared with the control group, the ultrasound indexes, alanine aminotransferase (ALT), γ-glutamyl transferase (GGT) and alkaline phosphatase (ALP) levels were significantly increased in the early group (all P<0.05), and the ultrasound indexes in the medium-to-long group were significantly increased, whereas the GGT level was significantly decreased (all P<0.05). Compared with the early group, the right oblique diameter of liver, ALT, GGT and ALP levels were significantly decreased in the medium-to-long group (all P<0.05). Compared with the control group, the sound touch elastography (STE) and sound touch quantify (STQ) values of liver and STE value of spleen in the early group and medium-to-long group were significantly increased (all P<0.05). Compared with the early group, the ultrasound elastography indexes of liver and spleen in the medium-to-long group were remarkably decreased (all P<0.05). The ultrasound elastography indexes of liver were weakly correlated with the ALT, aspartate aminotransferase (AST) and GGT levels, significantly correlated with ALP level. The STE value of spleen was weakly correlated with the ALP level. The STE value of liver was significantly correlated with the STQ value of liver. The STE and STQ values of liver were weakly correlated with the STE value of spleen. Conclusions The characteristics of liver elasticity in stable recipients after liver transplantation are various among different stages. Persistent monitoring of liver elasticity may provide a novel non-invasive monitoring method during follow-up after liver transplantation. [ABSTRACT FROM AUTHOR]
