ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the therapeutic efficacy of VICP+L-ASP/TKI on adult patients with B-ALL and to explore the influence factors.</p><p><b>METHODS</b>Forty-one adult B-ALL patients treated with VICP+L-ASP/TKI from August 2008 to June 2014 were following-up. The complete remission(CR) rate, toxicity, overall survival(OS) and event free survival(EFS) after induction treatment were analyzed, the therapeutic outcome of patients between different risk stratification subgroups was compared, the influence of standardized consolidatory and maintaining treatment as well as allogeneic hematopoietic stem cell transplantation(allo-HSCT) on survival time was analyzed.</p><p><b>RESULTS</b>The early death not occurred in 41 patients with B-ALL including 37 cases with CR; the CR rate of 1 course treatment was 90.2%. The follow-up time lasted to March 17, 2015, the median follow-up time was 25(9-79) months; the 1 year OS rate was 75.3%, the EFS rate was 58.3%. Analysis of risk factors showed that the initial WBC count over 30×10/L, LDH over 250 U/L and minimal residual disease(MRD) over 10after treatment were poor prognostic factors. After remission, the standardized consolidatory treatment or allo-HSCT according to the "2012 China adult ALL diagnosis and treatment expert consensus" could improve long-term survival, 3 years OS rate was 73.8% and 61.5% respectively, 3 years EFS were 63.5% and 65.7% respectively. The main toxic and side effects were hematologic reactions, the hematologic adverse reaction of IV grade was observed in 97.6%(40/41) during induction treatment.</p><p><b>CONCLUSION</b>Induction chemotherapy based on VICP+L-ASP/TKI and standardized consolidatory after remission according to the "2012 China adult acute lymphoblastic leukemia diagnosis and treatment expert consensus" can improve the therapeutic efficacy. The allo-HSCT should be actively performed for B-ALL paients with high risk(elevated initial WBC count and LDH level); at some time, the regularly monitoring MRD and adjusting therapeutic protocol according to monitoring result can promote the prognosis of adult B-ALL patients.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To establish a human gallbladder carcinoma cell line derived from a metastatic gallbladder carcinoma and identify its biological characteristics.</p><p><b>METHODS</b>Tissue samples were separated from the surgical specimen obtained from a patient with metastatic carcinoma and single-cell suspension was prepared. Then the cells were cultured in DMEM medium supplemented with 15% fetal bovine serum. The morphology of tumor cells was observed under an electron microscope. The cell growth curve was plotted. The tumorigenicity of the cell line was studied by subcutaneous inoculation in SCID mice. The cells were infected by lentiviral vector carrying fluorescent report genes (lenti-GFP and lenti-Red2) separately for expressions of GFP and Red2, respectively.</p><p><b>RESULTS</b>A novel metastatic gallbladder carcinoma cell line was successfully established and named "EH-GB1". It could be passaged for over 20 generations with typical malignant epithelial morphology and a stable growth cycle of 24 h. Tumors were formed in all of the 10 SCID mice inoculated with EH-GB1 cells subcutaneously, and the tumor cells were tumor marker CA19-9-positive. Continuous expressions of fluorescent report genes were observed in EH-GB1 cells infected by lenti-GFP and lenti-Red2.</p><p><b>CONCLUSION</b>EH-GB1 cells might be the first stable cell line of human gallbladder carcinoma established from a metastatic focus of gallbladder carcinoma. This cell line with continuous expressions of GFP and Red2 might be a novel and perfect experimental model for clinical and basic research on gallbladder carcinoma.</p>

Objective To explore the underlying relationship between hyperglycemic factors in type 2 diabe- tes.Methods Fifty seven type 2 diabetes with obesity (DM-OB)and 64 without obesity(DM-NOB)were recruited. Age,body mass index(BMI),hemoglobin A1c (HbA1c),homeostasis model assessment-2 insulin resistance (HO- MA-IR),high-sensitivity C-reactive protein (hsCRP),fasting plasma glucose,postprandial plasma glucose (PPG), postprandial glucose excursion(PPGE),lipid profile,blood pressure were determined.Results DM-OB subjects had significantly higher HOMA-IR,BMI,DBP,TC,hsCRP,HbAlc,LDL-C when compared with DM-NOB sub- jects.Pearson correlation analysis,in DM-OB subjects,BMI,FBG,FPG,HOMA-IR,hs-CRP were all the posi- tive relative factors(P all
