Purpose: Although patients with invasive papillary carcinoma (IPC) often have favorable prognoses, it remains unclear whether this special type of breast cancer represents a distinct morphological entity with its own biological features and clinical behavior distinct from those of invasive ductal carcinoma (IDC) and whether its four molecular subtypes are associated with different prognoses. Methods: The study is a retrospective analysis of a large patient cohort from a single institution. 284 IPC samples were collected from January 2000 to May 2011. 300 IDC cases were selected randomly from 13,428 cases of IDC during the same periods. We assessed the clinicopathologic characteristics, molecular features, and prognostic value of IPC (n = 284) and compared them to those of IDC (n = 300). Clinicopathologic features and survival status of the four subtypes of IPC were also evaluated. Results: IPC differed from IDC with respect to age upon diagnosis, tumor grade, lymph node status, and menopausal status (P < 0.05). IPC was associated with a better 5-year overall survival rate (OS) (92.77 vs. 87.95 %) and disease-free survival rate (DFS) (87.95 vs. 80.72 %) than IDC. Tumors of the luminal A subtype had a better 5-year OS (97.78 %) and DFS (95.56 %) than other subtypes. Conclusions: The biologic behavior of IPC is more favorable to patient outcome than that of IDC. The chance of pure IPC causing death without an intervening event of a different histologic type is exceptionally low. Luminal A subtypes have better outcomes when compared to the other subtypes. © 2012 Springer-Verlag.

Invasion and metastasis of hepatocellular carcinoma (HCC) is a major cause for lethal liver cancer. Signaling pathways associated with cancer progression are frequently reconfigured by aberrant phosphorylation of key proteins. To capture the key phosphorylation events in HCC metastasis, we established a methodology by an off-line high-pH HPLC separation strategy combined with multi-step IMAC and LC–MS/MS to study the phosphoproteome of a metastatic HCC cell line, MHCC97-H (high metastasis). In total, 6593 phosphopeptides with 6420 phosphorylation sites (p-sites) of 2930 phosphoproteins were identified. Statistical analysis of gene ontology (GO) categories for the identified phosphoproteins showed that several of the biological processes, such as transcriptional regulation, mRNA processing and RNA splicing, were over-represented. Further analysis of Kyoto Encyclopedia of Genes and Genomes (KEGG) annotations demonstrated that phosphoproteins in multiple pathways, such as spliceosome, the insulin signaling pathway and the cell cycle, were significantly enriched. In particular, we compared our dataset with a previously published phosphoproteome in a normal liver sample, and the results revealed that a number of proteins in the spliceosome pathway, such as U2 small nuclear RNA Auxiliary Factor 2 (U2AF2), Eukaryotic Initiation Factor 4A-III (EIF4A3), Cell Division Cycle 5-Like (CDC5L) and Survival Motor Neuron Domain Containing 1 (SMNDC1), were exclusively identified as phosphoproteins only in the MHCC97-H cell line. These results indicated that the phosphorylation of spliceosome proteins may participate in the metastasis of HCC by regulating mRNA processing and RNA splicing. © 2015 by the authors; licensee MDPI, Basel, Switzerland.

We report a 74-year-old woman who presented with bilateral chorea and no known history of diabetes. Movement disorders such as chorea can be observed in patients presenting with hyperglycemia. The occurrence of hemichorea-hemiballism has been increasingly associated with nonketotic hyperglycemia in the medical literature. The chorea disappeared completely after correction of the hyperglycemia. © 2015 Elsevier Ltd. All rights reserved.

Nasal NK/T cell lymphoma is a rare and distinct type of extranodal Non-Hodgkin's lymphoma. Current study has proved that Radiotherapy is the most effective treatment method in the early stage nasal NK/T cell lymphoma, but there is no universal standard for concrete radiotherapy modality, such as the radiation target, the radiation dose and preventive neck radiation. Most studies have proved that radiotherapy of extended field and higher dose achieved good effect in early stage nasal NK/T cell lymphoma. And the studies also do not suggested preventive neck radiation in local stage patients, but it need further study in the extensive stage patients.

Background: Previous studies reported the association between single nucleotide polymorphism (SNP) of IL15 receptor alpha (IL15RA) gene with susceptibility to ossification of the posterior longitudinal ligament of the spine (OPLL). However, the results were still in controversy. Therefore, the purpose of the present study was to investigate the association between SNPs of IL15RA gene with susceptibility to OPLL in a Chinese Han population. Methods: A total of 235 OPLL patients and 250 age-matched healthy controls were recruited. All the subjects were genotyped using the PCR (polymerase chain reaction)-based invader assay. A case-control study was performed to define the contribution of rs2228059 and rs2296139 to predisposition of OPLL. We also performed subgroup analysis according to the different gender. Results: A significant association of rs2228059 with OPLL was observed in the Chinese Han population (p <0.001, OR = 1.63, 95% CI = 1.26-2.11). The subgroup analysis showed that there was a significant association between the allele frequency of rs2228059 and the susceptibility of OPLL in males (p = 0.002, OR = 1.72, 95% CI = 1.23-2.42). However, there was no significant association between SNP of rs2296139 and susceptibility to OPLL. Conclusions: The present study demonstrates that the SNP of rs2228059 in IL15RA gene is associated with susceptibility to OPLL in a Chinese Han population, especially in males.
