This paper proposes a dynamic RWA scheme using fuzzy logic control on IP/GMPLS over WDM networks to achieve the best quality of network transmission. The proposed algorithm dynamically allocates network resources and reserves partial bandwidth based on the current network status, which includes the request bandwidth, average utilization for each wavelength and its coefficient of variance （C.V.） of data traffic, to determine whether the connection can be set tip. Five fuzzy sets for request bandwidth, average rate and C.V. of data traffic are used to divide the variable space： very large （LP）, large （SP）, normal （ZE）, small （SN）, and very small （LN）. Setting the fuzzy limit is a key part in the proposed algorithm. The simulation of scenarios in this paper has two steps. In the first step, the adaptive fuzzy limits are evaluated based on average transmission cost pertaining to ten network statuses. The second step is to compare the proposed algorithm with periodic measurement of traffic （PMT） in ATM networks in six network situations to show that the proposed FC-RWA algorithm can provide better network transmission.

AIM: To investigate the correlation between gammaglutamyl transpeptidase (γ-GTP) expression in the primary HCC and post-resection recurrence and its biological ***: Forty consecutive patients having curative resection for HCC were included in this study. The primers for reverse-transcription polymerase chain reaction (RTPCR) were corresponding to the 5'-noncoding human γ-GTP mRNA of fetal liver (type A), HepG2 cells (type B),and placenta (type C). Both the cancer and non-cancerous tissues of the resected liver were analyzed. The correlations between the expression of γ-GTP and the clinicopathological variables and outcomes (recurrence and survival) were ***: Those with type B γ-GTP mRNA in cancer had significant higher recurrence rate than those without it (63.6 % vs 14.3 %). Both those with type B in cancer and in non-cancer died significantly more than those without it (45.5 % vs 0 % and 53.6 % vs 0 %, respectively). By multivariate analysis, the significant predictors of recurrence included high serum AFP (P=0.0108), vascular permeation (P=0.0084), and type B γ-GTP mRNA in non-cancerous liver (P=0.0107). The significant predictors of postrecurrence death included high serum AFP (P=0.0141),vascular permeation (P=0.0130), and daughter nodules (P=0.0053). As to the manifestations (recurrent number ≥2, recurrent extent≥2 segments, extra-hepatic metastasis, and death) in recurrent patients, there were no statistical significant differences between those with type B in the primary tumor and those without it. The difference between those with type B in non-cancerous liver and those without it also was not ***: Patients of HCC with type B γ-GTP mRNA both in cancer and in non-cancerous tissue had a worse outcome, earlier recurrence, and more post-recurrence death.

AIM: To evaluate mutant p53 gene in primary hepatocellular carcinoma and to investigate the correlation between it and the recurrence of hepatocellular ***: Mutations of p53 gene were examined using antihuman p53 monoclonal antibody and immunohistochemical staining in 79 resected hepatocellular carcinomas. The correlations among variables of p53 positivity and invasiveness, disease free interval and survival were *** addition, in those who developed recurrence, the correlation among p53 positivity, clinical features and postrecurrence survival were also ***: Of these 79 cases, 64 (81%) had p53 *** patients with mutant p53 positivityhad significantly more tumor recurrence (76.6 % vs 40.0 %, P=0.0107).However, the COX proportional hazards model showed that p53 overexpression had only weak correlations with recurrence free interval and survival time (P=0.088 and 0.081), which was probably related to the short duration of follow-up. The invasiveness variables may be predictors of HCC recurrence. On univariate analysis, more patients with mutant p53 positivity had vascular permeation [78.1vs 40.0 %, P=0.0088, O.R. (odds ratio) =5.3], grade Ⅱ-ⅣV differentiation (98.4 vs 80.0 %, P=0.0203, O.R. =15.7), no complete capsule (82.8 vs 53.3 %, P=0.0346, O.R. =4.2)and daughter nodules (60.9 vs. 33.3 %, P=0.0527, O.R.=3.1) than patients with negative p53 staining. Onmultivariate analysis, only vascular permeation and grade of differentiation remained significant (P=0.042 and 0.012).There was no statistically significant correlation betweenthe status of p53 in the primary lesion and the clinical features of recurrent hepatocellular carcinomas examined,including extrahepatic metastasis (P=0.1103) and the number of recurrent tumors (P= 1.000) except for diseaseover more than one segment in the extent of recurrent tumors (P=0.0043). The post-recurrence median survival was lower in patients in whom p53 mutation had been detected in the primar

AIM: To investigate the prognostic value of the expression of connexin (Cx) 26, 32 and 43 messenger RNA (mRNA) in hepatocellular carcinoma (HCC) tissues. METHODS: Using a reverse-transcriptase polymerase chain reaction (RT-PCR), Cx 26, Cx 32 and Cx 43 mRNAs were determined in the liver tissues of 15 controls and in HCC tissues of 25 patients undergoing curative hepatic resection. The patients were followed up ***: Cx 26 and Cx 32 mRNAs were significantly lower in HCC tissues compared with controls (both P<0.01). By multivariate analysis, a lower level of Cx 26 and Cx 32 mRNA correlated significantly with a risk of HCC recurrence (P = 0.033) and recurrence-related mortality (P = 0.031,P= 0.031). Cx 43 mRNA was higher in HCC tissues compared with controls but did not correlate with postoperative recurrence or recurrence-related mortality. Other significant predictors of HCC recurrence included cellular dedifferentiation (P = 0.033), less encapsulation (P = 0.050), vascular permeation (P= 0.046), and daughter nodules (P= 0.046). Significant variables related to recurrence-related mortality consisted of cell dedifferentiation (P = 0.031), vascular permeation (P = 0.048), and daughter nodules (P = 0.048).The levels of Cx 26 and Cx 32 mRNAs correlated significantly with cell differentiation (P= 0.031). CONCLUSION: A low expression of Cx 26 and Cx 32 mRNAs in HCC tissues is predictive of postoperative recurrence of HCCs.

VoD (video on demand) service is regard as one of the most important services in next decade. It requires high speed and huge bandwidth to guarantee the QoS (quality of service). EPON (Ethernet passive optical network) is regarded as one of the best solutions on access network, due to high speed and low cost. The star-ring EPON architecture is an evolution of EPON which provides better local transmission and fault tolerance capability. In addition, the CDN (content delivery network) mechanism, in which the video content is cached at a location closer to the user, is a widely used methodology to reduce the latency of VoD service. Therefore, in this paper, we propose a mechanism which combines the advantage of star-ring based EPON architecture and CDN mechanism to improve QoS. We design a new Sub-OLT (optical line terminal) which includes storage to store video files and serve at local. Thus, it can reduce the bandwidth between OLT and ONU (optical network unit). Simulation results have shown that our proposed mechanism can improve the system performance and QoS in terms of packet delay and jitter.
