Esophageal squamous cell carcinoma(ESCC) is a common malignancy in china,and TNM staging is the standard staging system for ESCC.However,in clinical practice,patients' prognosis is not always consistent with the staging.This phenomenon may be attributed from the fact that the current limitation and imperfect of the TNM staging system,and besides,another possible reason might be that some prognostic factors for ESCC other than TNM descriptors may exist.Among all the prognostic factors for ESCC,molecular biomarkers received widely concern.We searched the literatures and identified 12 molecular biomarkers that received the most concern and validated them in our single surgeon team.The results showed that only P21,COX-2 and E-cadherin were significant prognostic factors for ESCC in this series.Therefore,in the current study,we reviewed the literature regarding the prognostic significance of the above mentioned three biomarkers for clinical reference.

OBJECTIVETo detect cholesteryl ester transfer protein (CETP) levels, frequencies of CETP D442G and I 14A mutations and characteristics of abnormal lipids in patients with cardio-cerebro vascular diseases.
METHODSNinety-four myocardial infarction (MI) patients, 110 stroke patients and 335 healthy controls were selected. The CETP concentration was determined using ELISA. The CETP activity was measured using a substrate of (14)C-radiolabeled discoidal bilayer particles. The CETP gene mutations were detected by PCR-RFLP.
RESULTSThe CETP concentrations in the MI and stroke group, were higher than those in the controls. The gene mutation frequencies of D442G in the MI, stroke and control group were 3.5%, 3.6% and 5%, respectively, and the frequencies of I 14A were 1.05%, 0.91% and 1%, respectively. One case of D442G homozygote was detected in the healthy group. The frequency of two CETP gene mutations showed no significant difference among the patients and controls. The CETP concentration and activity in subjects with CETP mutations were one-third of those in the control group. The level of HDL-C, apo-A1 increased in the mutation subjects, while the TG level decreased.
CONCLUSIONSThe CETP level increased significantly in patients with cardio-cerebrovascular diseases. The carriers of CETP deficiency had CETP and lipid abnormalities.

OBJECTIVETo evaluate the long-term outcome of immunosuppressive therapy (IST) in patients with severe aplastic anemia (SAA).
METHODSHematopoietic recovery (peripheral blood cell counts, bone marrow aspirates, bone marrow biopsy, in vitro culture of hematopoietic progenitors), immunity of T lymphocyte, quality of life and side-effects of the therapy were assessed in 50 SAA patients who have survived more than 3 years after IST.
RESULTSAt 3 years, 4 years and 5 years follow-up, 81.5% (13 cases), 86.7% (13 cases) and 89.5% (17 cases) of the SAA patients reached and maintained normal peripheral blood cell counts, 93.4% (15 cases), 93.3% (14 cases) and 94.7% (18 cases) showed normal bone marrow pictures, and 37.5% (6 cases), 40.0% (6 cases) and 73.7% (14 cases) had normal yields of bone marrow cell culture, respectively. Overall, 86.0% (43 cases), 94.0% (47 cases) and 52.0% (26 cases) of the total SAA patients were normalized in peripheral blood counts, bone marrow picture and culture of hematopoietic progenitor yields, respectively. During the follow-up, 88.0% (44 cases) of the patients achieved 100 of Karnofsky scores; 26 of the 31 patients (83.9%) who received bone marrow biopsy showed normal histological pictures, and 29 of 37 patients (78.4%) tested had normal subsets of T lymphocytes. No clonal disease was found. The late side-effects of IST were mild. All of the parameters tested were normal in 24 patients.
CONCLUSIONAfter IST, the hematopoietic function of bone marrow, the immunity of the T lymphocyte and the life quality were normalized with few side-effects in patients with SAA. These patients would probably be cured.

[Abstract] Objective: To investigate the effect of lncRNA MAFG-AS1/ miR-11181-3p/GLG1 axis on cell migration, invasion and aerobic glycolysis of gastric cancer (GC) cells and its possible mechanism. Methods: AGS, a GC cell line with relatively high expression of MAFG-AS1, was selected as the study object. qPCR was used to detect RNA expression levels of MAFG-AS1, miR-11181-3p and GLG1. Transwell and glycolysis analysis were used to investigate cell migration, invasion and aerobic glycolysis. Bioinformatics analysis and Dual luciferase reporter gene assay were used to analyze the interaction among MAFG-AS1, miR-11181-3p and GLG1. Results: Knockdown of MAFG-AS1 significantly up-regulated miR-11181-3p and down-regulated GLG1 expression (both P<0.01), and significantly inhibited migration, invasion and aerobic glycolysis of GC cells (all P<0.01). Luciferase reporter gene assay confirmed that MAFG-AS1 competitively sponged miR-11181-3p (P<0.01). Inhibition of miR-11181-3p or overexpression of GLG1 partially reversed the inhibitory effect of MAFG-AS1 knockdown on GC cell migration, invasion, and aerobic glycolysis (all P<0.05 or P<0.01). Conclusion: MAFG-AS1 promotes cell migration, invasion and aerobic glycolysis of GC cells via miR-11181-3p/GLG1 axis, and may be a potential molecular target for GC diagnosis and therapy.
