Lymphadenectomy for urothelial carcinoma of the upper urinary tract has attracted the attention of physicians. the mapping study of lymphatic spread has shown that a relatively wide area should comprise the regional nodes for tumors of the right renal pelvis or the right upper two-thirds of the ureter. A prospective study showed that an anatomical templatebased lymphadenectomy significantly improved patient survival in tumors of the renal pelvis. this benefit was more evident for patients with p t2 stage tumors or higher. the risk of regional node recurrence is significant reduced by template-based lymphadenectomy,which is likely to be associated with improved patient survival. the removal of lymph node micrometastases is assumed to be the reason for therapeutic benefit following lymphadenectomy. the number of resected lymph nodes can be used to assess the quality of lymphadenectomy,but not to determine the extent of lymphadenectomy. the guidelines currently recommend lymphadenectomy for patients with muscle-invasive disease,even though the current recommendation grades are still low. the present limitation of lymphadenectomy is the lack of standardization of the extent of lymphadenectomy and the randomized trials. Further studies are warranted to collect the evidence to support lymphadenectomy.

In the outer periclinal cytoplasm of leaf epidermal cells of an aquatic angiosperm Vallisneria, blue light induces ＂chloroplast de-anchoring＂, a rapid decline in the resistance of chloroplasts against centrifugal force. Chloroplast de- anchoring is known induced within lmin of irradiation with high-fluence-rate blue light specifically, preceding the com- mencement of chloroplasts migration toward the anticlinal cytoplasm. However, its regulatory mechanism has remained elusive, although pharmacological analysis suggested that a calcium release from intracellular calcium stores is necessary for the response, in search of the responsible photoreceptors, immunoblotting analysis using antibodies against phototropins demonstrated that cross-reactive polypeptides of 120-kDa exist in the plasma-membrane fraction prepared from the leaves. In vitro phosphorylation analysis revealed that 120-kDa polypeptides were phosphorylated by exposure to blue light in a fluence-dependent manner. the blue-light-induced phosphorylation activity was sensitive to a Ser/thr kinase inhibitor, staurosporine, and unusually was retained at a high level for a long time in darkness. Furthermore, phototropin gene homologs （Vallisneria PHOtOtROPINI and PHOtOtROPIN2） expressed in leaves were isolated. We propose that calcium- regulated chloroplast de-anchoring, possibly mediated by phototropins, is an initial process of the blue-light-induced avoidance response of chloroplasts in Vallisneria.

We discuss a supersymmetric model with discrete flavor symmetry A4×Z3. the additional scalar fields which contribute masses of leptons in the Yukawa terms are introduced in this model. We analyze their scalar potential and find that they have various vacuum structures. We show the relations among 24 different vacua and classify them into two types. We derive expressions of the lepton mixing angles, Dirac CP violating phase and Majorana phases for the two types. the model parameters which are allowed by the experimental data of the lepton mixing angles are different for each type. We also study the constraints on the model parameters which are related to Majorana phases. the different allowed regions of the model parameters for the two types are shown numerically for a given region of two combinations of the CP violating phases.

Basing upon the Weber-Fechner Law with respect to the stimulus (distance-headway) to the vehicle driver and the driver’s sensation (speed), the characteristic speed Vβ is defined, which is the critical vehicles flow speed just before going to congestion in road traffic flow. From the information of real time measurement of traffic flow speed (V) and time-headway (t) at the specific positions along the road, the value of Vβ is calculated and used for forecasting the flow. Discussed is how to use each Vβ to forecast the congestion. the CN system devoted to the management of road traffic flow is proposed. the idea may contribute not only to easing the traffic flow but also to optimizing it to get high efficient traffic flow.

AIM： to estimate the contribution of autoimmune thrombocytopenia to hepatitis C virus-related liver cirrhosis （type C cirrhosis）, we evaluated the influence of splenectomy upon platelet-associated immunoglobulin G （PAIgG） levels and platelet numbers. MEtHODS： PAIgG titers and immune markers were determined in 24 type C cirrhotic patients with an intact spleen, 17 type C cirrhotic patients submitted to splenectomy, and 21 non-C cirrhosis with an intact spleen. RESULtS： thrombocytopenia （PLt〈15×10^4/μL） in type C cirrhosis was diagnosed in all patients with an intact spleen, 8 patients submitted to splenectomy, and in 19 non-C cirrhosis with intact spleen. Elevated titers of PAIgG at more than 25.0 ng/107cells were detected in all cirrhotic patients except for one splenectomized patient. PAIgG titers （ng/10^7cells） were significantly higher in the type C cirrhosis with an intact spleen （247.9 ± 197.0） compared with the splenectomized patients （125.6±87.8） or non-C cirrhosis （152.4± 127.4）. PAIgG titers were negatively correlated with platelet counts in type C cirrhotic patients with an intact spleen. In comparison with the type C cirrhosis with an intact spleen, the splenectomized patients had a reduced CD4/CD8 ratio and serum neopterin levels. the spleen index （cm^2） was negatively correlated with platelet counts in the non-C cirrhosis, but not in the type C cirrhosis. CONCLUSION： Our data indicate that the autoimmune mechanism plays an important role in thrombocytosis complicated by HCV-positive cirrhosis. In addition, splenectomy may impair t cells function through, at least in part, a reduction of CD4/CD8 ratio, consequently suppressing PAIgG production.
