AIM: To compare the short term outcome of endoscopic submucosal dissection(ESD) with that of laparoscopic colorectal resection(LC) for the treatment of early colorectal epithelial neoplasms that are not amenable to conventional endoscopic removal. METHODS: This was a retrospective cohort study. The clinical data of all consecutive patients who underwent ESD for endoscopically assessed benign lesions that were larger than 2 cm in diameter from 2009 to 2013 were collected. These patients were compared with a cohort of controls who underwent LC from 2005 to 2013. Lesions that were proven to be malignant by initial endoscopic biopsies were excluded. Mid and lower rectal lesions were not included because total mesorectal excision, which bears a more complicated postoperative course, is not indicated for lesions without histological proof of malignancy. Both ESD and LC were performed by the same surgical unit with a standardized technique. The patients were managed according to a standard protocol, and they were closely monitored for complications after the procedures. All hospital records were reviewed, and the following data were compared between the ESD and LC groups: patient demographics, size and location of the lesions, procedure time, shortterm clinical outcomes and pathology results. RESULTS: From 2005 to 2013, 65 patients who underwent ESD and 55 patients who underwent LC were included in this study. The two groups were similar in terms of sex(P = 0.41) and American Society of Anesthesiologist class(P = 0.58), although patients in the ESD group were slightly older(68.6 ± 9.4 vs 64.6 ± 9.9, P = 0.03). ESD could be accomplished with a shorter procedure time(113 ± 66 min vs 153 ± 43 min, P < 0.01) for lesions of comparable size(3.0 ± 1.2 cm vs 3.4 ± 1.4 cm, P = 0.22) and location(colon/rectum:59/6 vs colon/rectum: 52/3, P = 0.43). ESD appeared to be associated with a lower short-term complication rate, but the difference did not reach statistical significance(10.8%

Patients with hepatocellular carcinoma have a very short life expectancy if they receive no surgical interven- tion. A relatively new surgical technique termed ＂Associating Liver Partition and Portal Vein Ligation for Staged Hepa- tectomy＂（ALPPS） has been employed for inducing rapid hypertrophy of the future liver remnant for patients waiting for hepatectomy. As portal vein embolization may not result in satisfactory hypertrophy before tumor progression occurs, ALPPS can be an alternative for patients with advanced hepa- tocellular carcinoma. Herein we describe an ALPPS procedure with tumor thrombectomy for a patient who had a small left liver lobe and a large hepatocellular carcinoma involving the whole right liver lobe and the middle hepatic vein and extend- ing into the inferior vena cava. In the first-stage operation, the right portal vein was controlled and divided with a Hemolock. The right hepatic artery was well protected. Hepatic transec- tion was performed with a 1-cm margin from the tumor. The middle hepatic vein trunk was preserved. Ten days afterwards, there was significant hypertrophy of the left lateral section of the liver, and the second-stage operation was conducted. Ex- tended right hepatectomy and tumor thrombectomy were per- formed under sternotomy and total vascular exclusion. The patient had good recovery and was free of disease 10 months after the operation. ALPPS may be a good treatment option even for patients with advanced disease if carried out at high- volume centers.

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.

With improvements in survival, liver trans- plant recipients now suffer more morbidity from long-term immunosuppression. Considerations were given to develop individualized immunosuppression based on their risk of re- jection. METHOD： We retrospectively analyzed the data of 788 liver transplants performed during the period from October 1991 to December 2011 to study the relationship between acute cel- lular rejection （ACR） and various clinical factors. RESULTS： Multivariate analysis showed that older age （P=0.04, OR=0.982）, chronic hepatitis B virus infection （P=0.005, OR= 0.574）, living donor liver transplantation （P=0.02, OR=0.648） and use of interleukin-2 receptor antagonist on induction （P〈0.001, OR=0.401） were associated with fewer ACRs. Patients with fulminant liver failure （P=.004, OR=4.05） were more likely to develop moderate to severe grade ACR. CONclUSIONS： Liver transplant recipients with older age, chronic hepatitis B virus infection, living donor liver trans- plantation and use of interleukin-2 receptor antagonist on in- duction have fewer ACR. Patients transplanted for fulminant liver failure are at higher risk of moderate to severe grade ACR. These results provide theoretical framework for developing individualized immunosuppression.

Background: Von Hippel–Lindau(VHL) syndrome is a dominantly inherited multisystem cancer syndrome caused by a heterozygous mutation in the VHL tumor suppressor gene. Previous studies suggested that similar populations of Caucasian and Japanese patients have similar genotype or phenotype characteristics. In this comprehensive study of East Asian patients, we investigated the genetic and clinical characteristics of patients with VHL ***: To create a registry of clinical characteristics and mutations reported in East Asian patients with VHL syndrome, we conducted a comprehensive review of English language and non?English language articles identi?fied through a literature search. Publications in Japanese or Chinese language were read by native speakers of the language, who then performed the data ***: Of 237 East Asian patients with VHL syndrome, 154 unique kindreds were identified for analysis. Analyzed by kindred, missense mutations were the most common(40.9%, 63/154), followed by large/complete deletions(32.5%, 50/154) and nonsense mutations(11.7%, 18/154). Compared with a previously reported study of both East Asian and non?East Asian patients, we found several key differences. First, missense and frameshift mutations in the VHL gene occurred less commonly in our population of East Asian patients(40.9% vs. 52.0%; P = 0.012 and 8.4% vs. 13.0%; P < 0.001, respectively). Second, large/complete deletions were more common in our population of East Asian patients(32.5% vs. 10.5%; P < 0.001). Third, phenotypically, we observed that, in our population of East Asian patients with VHL syndrome, the incidence of retinal capillary hemangioblastoma was lower, whereas the incidence of renal cell carcinoma was ***: Evidence suggests that the genotypic and phenotypic characteristics of East Asian patients with VHL syndrome differ from other populations. This should be considered when making screening recommendations for VHL syndrome in Asi
