AIM: To analyze the prognostic factors influencing the overall survival of peripheral cholangiocarcinoma (PCC) patients undergoing surgical treatment during 25 years at a single institution. METHODS: This study retrospectively reviewed prospectively collecting data about 373 patients with historically proven PCC who underwent surgical treatment between 1977 and 2001. RESULTS: Three hundred and seventy-three PCC patients (159 men and 214 women) underwent surgical treatment from 1977 to 2001. Among them, 187 PCC patients underwent hepatectomy and 135 had curative resection (curative resectability rate: 36.2%). The follow-up duration ranged from 1.05 to 167.6 mo (mean/median = 14.1/7.2 mo). Overall cumulative survival rates at 1, 3, and 5 years were 32.5%, 9.2%, and 4.1%, respectively. Univariate log-rank analysis identified the following as adverse influences on overall survival: presence of symptoms, absence of mucobilia, elevated CEA and CA 19-9 levels, non-papillary tumor type, receiving non-hepatectomy, advanced tumor staging, lack of post-operative chemotherapy, and radiotherapy. Meanwhile, multivariate Cox's proportional hazard analysis demonstrated that absence of mucobilia, non-papillary tumor type, advanced tumor staging, non-hepatectomy, and lack of post-operative chemotherapy were the five independent prognostic factors that adversely affected overall survival. CONCLUSION: Favorable overall survival of PCC patients undergoing surgical treatment depends on early tumor stage, presence of mucobilia, papillary tumor type, hepatic resection, and post-operative chemotherapy.

Enterovesical fistulas are not uncommon in patients with inflammatory or malignant colonic disease, however, fistulas secondary to primary bladder carcinomas are extremely rare. We herein reported a patient presenting with intractable urinary tract infection due to enterovesical fistula formation caused by a squamous cell carcinoma of the urinary bladder. This patient underwent en bloc resection of the bladder dome and involved ileum, and recovered uneventfully without urinary complaint. To the best of our knowledge, this is the first case reported in the literature.

Primary squamous cell carcinoma (SCC) of the liveris rare. Totally nine such cases have been reportedin the literature. Primary SCC of the liver has beenreported to be associated with hepatic teratoma,hepatic cyst, or hepatolithiasis. Complete remission ofpoorly differentiated SCC of the liver could be achievedby systemic chemotherapy followed by surgery orremarkably respond to hepatic arterial injection of lowdose chemotherapeutic drugs. Here we report the fi rstcase of primary SCC of the liver presenting as a solidtumor and receiving successful hepatic resection with9-mo disease free survival.

AIM:To clarify the benefit of surgical excision for patients with extrahepatic metastases of hepatocellular carcinoma(HCC). METHODS:We retrospectively reviewed the medical records of 140 patients with pathologically proven extrahepatic metastases of HCC and evaluated the outcomes of those who had undergone surgical resection(SR)for extrahepatic metastatic *** made on the basis of extrahepatic metastatic sites were also examined. RESULTS:The survival rates of patients who underwent SR of extrahepatic metastases were significantly better than those of patients who did not receive SR. For the SR group,1-and 3-year survival rates were 24%and 7%,respectively,while for the non-resection group,the survival rates were 8%and 0%,respec- tively(P<0.0001).Survival rates related to metastatic sites were also significantly superior after SR of extrahepatic metastases:median survivals were 32 mo with lung metastasis,10 mo with bone metastasis,6.1 mo with brain metastasis. CONCLUSION:SR can provide survival benefits forpatients with 1 or 2 isolated extrahepatic metastases and who concurrently exhibit good hepatic functional reserve and general performance status as well as successful treatment of intrahepatic HCC.

AIM: To analyze the predictive factors for lymph node metastasis (LNM) in early gastric cancer (EGC). METHODS: Data from patients surgically treated for gastric cancers between January 1994 and December 2007 were retrospectively collected. Clinicopathological factors were analyzed to identify predictive factors for LNM. RESULTS: Of the 2936 patients who underwent gas-trectomy and lymph node dissection, 556 were diag-nosed with EGC and included in this study. Among these, 4.1% of patients had mucosal tumors (T1a) with LNM while 24.3% of patients had submucosal tumorswith LNM. Univariate analysis found that female gen-der, tumors ≥ 2 cm, tumor invasion to the submucosa, vascular and lymphatic involvement were significantly associated with a higher rate of LNM. On multivariate analysis, tumor size, lymphatic involvement, and tumor with submucosal invasion were associated with LNM. CONCLUSION: Tumor with submucosal invasion, size ≥ 2 cm, and presence of lymphatic involvement are predictive factors for LNM in EGC.

从Jacob和Wick所推导的具有自旋粒子的散射矩阵元一般表示式出发,采用适当近似后,分析了中子引起Th230,Th232,U234,U236,U238裂变的阈能附近碎块角分布的实验数据。分析结果说明:1)阈能附近碎块角分布可以用裂变是通过鞍点上少数转动带（每一带具有确定的宇称）来解释;2)这些转动带与Nilsson的渐近能谱图所预言的基本上一致。同时利用对称裂变鞍点比非对称裂变鞍点高的观点,讨论了裂变碎块角分布各向异性与质量比之间的关系。

我们把Migdal的关于基态原子核转动惯量的半经典近似的推导,推广到激发态（T≠0）情形;并由此计算了裂变碎块角分布参数K02。与实验数据比较的结果表明:在现有近似下,原子核的对相互作用能解释U区裂变核在低激发能（Eexc≤15MeV）时,K02“反常”小的现象,同时利用对相互作用与角动量的依赖关系,可以定性地解释Pb附近裂变核并没有这种“反常”现象。

The development of the CNS in vertebrate embryos involves the generation of different sub-types of neurons and glia in a complex but highly-ordered spatio-temporal manner. Zebrafish are commonly used for exploring the development, plasticity and regeneration of the CNS, and the recent development of reliable protocols for isolating and culturing neural stem/progenitor cells(NSCs/NPCs) from the brain of adult fish now enables the exploration of mechanisms underlying the induction/specification/differentiation of these cells. Here, we refined a protocol to generate proliferating and differentiating neurospheres from the entire brain of adult zebrafish. We demonstrated via RT-qPCR that some isoforms of ip3 r, ryr and stim are upregulated/downregulated significantly in differentiating neurospheres, and via immunolabelling that 1,4,5-inositol trisphosphate receptor(IP3 R) type-1 and ryanodine receptor(RyR) type-2 are differentially expressed in cells with neuron-or radial glial-like properties. Furthermore, ATP but not caffeine(IP3 R and RyR agonists, respectively), induced the generation of Ca^(2+) transients in cells exhibiting neuron-or glial-like morphology. These results indicate the differential expression of components of the Ca^(2+) -signaling toolkit in proliferating and differentiating cells. Thus, given the complexity of the intact vertebrate brain, neurospheres might be a useful system for exploring neurodegenerative disease diagnosis protocols and drug development using Ca^(2+) signaling as a read-out.

Primary torsion dystonia(PTD)is a clinically and genetically heterogeneous movement *** least thirteen different types of dystonia can be distinguished on a genetic basis.~1 The DYT1 gene was first mapped by Ozelius et al in 1989.~2(Kramer et)al^3 linked the same locus to PTD in 12 Ashkenazi Jewish families in *** patients with early-onset generalized PTD were caused by the same three base pair(GAG)deletion in the DYT1 gene on chromosome 9q34.^(1,4,5)The product of the gene is a protein called torsinA.~5(Although the)function of this protein is as yet uncertain,it is widely distributed throughout the brain with high levels in the substantia nigra compacta dopamine neurones.
