Objective To investigate multi-slice spiral CT (MSCT) and MRI features of stasis cirrhosis and the diagnostic value of MSCT and MRI. Methods MSCT and MRI findings of 35 patients with stasis cirrhosis were studied. The size of liver and spleen, the diameter of hepatic vein (HV), enhancement pattern of liver parenchyma, contrast medium reflux in inferior vena cava (IVC) and (or) HV, ascites, number of varices and correlated abnormalities were reviewed. Results The volume index of liver and spleen of 35 patients was 4 434.95 cm3 and 621.92 cm3 respectively. The mean diameter of HV of 27 patients (77.1%) was 3.61 cm and HV of other 8 patients (22.9%) were too small to show. Number of patients showed waves of borderline, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, varices and ascites was 5 (14.3%), 29 (82.9%), 20 (57.1%), 16 (45.7%), and 6 (17.1%), respectively. Correlated abnormalities included cardiac enlargement 4 cases (11.4%), pericardium thickening 11 cases (31.4%), and pericardial effusion 2 cases (5.7%). Conclusions Stasis cirrhosis mainly demonstrate liver enlargement, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, and slight portal hypertension. MSCT and MRI play invaluable roles in diagnosis, differential diagnosis and etiological diagnosis of stasis cirrhosis.

Objective To understand the risk factors of measles among babies under 8-months-old and people ≥15 years old,in Gansu province. Methods Laboratory-confirmed measles cases were divided into two groups among children below 8-months-old and those≥15 year olds. Descriptive epidemiology and 1∶3 case control study were conducted to find out those related risk factors as:hospital exposure,contact with measles cases,vaccination,history of measles etc. so as to determine the risk factors and appropriate control measures. Results Histories of hospital exposure,contact with measles cases and travelling to other cities were risk factors for measles among babies younger than 8-months and people≥15 year olds. Vaccination appeared a protective factor for people ≥15 years of age. From 42 cases and 126 controls,through multivariate analysis,results showed that hospital exposure was the only significant factor(OR=29.23,95%CI:2.82-302.89)for those babies younger than 8-months. Factors as hospital exposure and travelling among cities for 7-21 days before being infected,were with significant importance(OR=5.15,95%CI:2.28-11.63;OR=5.48,95%CI:1.38-21.69)for people ≥15 years of age,according to the observation from 74 cases and 222 controls. Conclusion In order to reduce the incidence of measles among babies under 8-month-old and people ≥15 years old, efforts on control of nosocomial infection should be strengthened,while the routine immunization coverage need to be increased for the children at higher risks,to reduce the source of infection.

Objective:To study the clinical features, therapeutic effects, survival time, and prognosis of patents with mantle cell lymphoma (MCL). Methods:Clinical data of 98 MCL patients admitted from January 2005 to December 2013 were retrospectively an-alyzed. Results:The median age was 61 years old, and the male-to-female ratio was 2.9∶1. Among these cases, 85 (86.8%) were in Ann Arbor stageⅢ-Ⅳ, 46 (46.9%) had bone marrow involvement, 25 (25.5%) had digestive tract involvement, and 53 chose R-CHOP as first-line treatment. The expected 3-year overall survival (OS) of these patients was only 61.4%. A total of 14 cases were treated with R-CHOP followed by ASCT. The expected 5-year OS was 92.3%, and the OS of the ASCT group was significantly higher than that of the R-CHOP group (75.5 months vs. 43.6 months, P=0.039). Elevated ESR,>60 years old, increased LDH level, B symptoms, and Ki-67≥25% were poor prognostic factors. Conclusion: Most patients with MCL were elder adults with bone marrow involvement. R-CHOP followed by ASCT had better clinical efficacy than conventional chemotherapy in the treatment of MCL.

OBJECTIVETo compare the prognostic value of different models in patients with early-stage diffuse large B-cell lymphoma (DLBCL).
METHODSEarly-stage DLBCL patients diagnosed from January 2000 to December 2012 were analyzed retrospectively. All patients received with at least 2 cycles of immunochemotherapy R-CHOP regimen (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) with or without radiotherapy. The prognostic value of international prognostic index (IPI) , revised IPI (R-IPI) and enhanced IPI (NCCN-IPI) was compared.
RESULTSNinety-seven cases of early-stage DLBCL were included in the study. The median age was 58 years (15-88 years) with a median follow-up of 34.7 months (range 7.3-77.4 months). The expected 5-year overall survival (OS) for entire group was 82%. There was no patient in the high risk group according to IPI or NCCN-IPI. According to IPI, the 5-year OS in the low, low intermediate, high intermediate risk groups were 95%, 38% and 60%, respectively. According to R-IPI, the 5-year OS in the very good, good, and poor risk groups were 93%, 75% and 60%, respectively. According to NCCN-IPI, the 5-year OS in the low, low intermediate, high intermediate risk groups were 92%, 85% and 29%, respectively.
CONCLUSIONNCCN-IPI would be of an ideal prognostic model for early-stage DLBCL patients.
