With the great success of imatinib mesylate(IM) and other tyrosine kinase inhibitor (TKI),chronic myelogenous leukemia (CML) is taken as a successful model of targeted therapies for human cancer.Although the emergence of TKI has greatly improved the prognosis of CML,the long-term TKI treatment may bring the problems of drug resistance,serious side effects,poor compliance,and heavy economic burden.Recently,people focus on whether patients would be cured after discontinuation of TKI treatment.Here,the progresses on discontinuation of TKI therapy in CML presented in the 54th American Society of Hematology (ASH) annual meeting were reviewed.

BACKGROUND: Parameters of platelet can reflect functions of coagulation. Granule membrane protein-140 (GMP-140), which is also called P-Selectin, in α-granules of platelets can reflect activities of platelet. Dysfunction of blood sugar and blood lipid in diabetic patients can result in complications such as thrombotic diseases.OBJECTIVE: To analyze the variation regulation of the platelet parameters and GMP-140 in patients with type 2 diabetes mellitus.DESIGN: A case-control study.SETTING:Department of Clinical Laboratory and Department of Endocrinology, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: From March to April 2005, forty-five patients with type 2 diabetes mellitus, who were treated at the Department of Endocrinology,Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology, were enrolled as diabetic group, and 45 healthy people, who were checked with health examination at the same period,were selected as control group. They all joined the experiment voluntarily. METHODS: Changes of quantity of blood platelet, mean platelet volume (MPV), platelet distribution width (PDW) and platelett-large cell ratio (PLCR) were analyzed with blood cell counter. GMP-140 was measured by enzyme-linked immunosorbent assay (ELISA), meanwhile, compared with those of the healthy people.MAIN OUTCOME MEASURES: Contents of the parameters of platelets and GMP-140 of subjects in the two group s.RESULTS: A total of 90 cases without drop out, 45 cases in the diabetic group and control group, respectively, were involved in the result analysis.①Comparison of the content of GMP-140 in the two groups: It was significantly higher in the diabetic group than that in the control group [(28.8±10.3) ,(9.1±5.6)μg/L(t=2.37,P ＜ 0.01 )]. ②Comparison of parameters of blood platelet of subjects of the two groups: The MPV, PDW and P-LCR in patients of the diabetic group were markedly higher than those in the control group (t=2.02, 2.02, 2.02, P ＜ 0.01 ), while the blood platelets (PLT)was dramatically lower than that in the control group (t=2.15, P ＜ 0.01 ).CONCLUSION: The MPV, PDW, P-LCR and the content of GMP-140 of patients with type 2 diabetes mellitus significantly increase, while the PLT decreases, which indicate that platelet activity enhances and the consumption of platelet increases in patients with type 2 diabetes mellitus.

Objective To investigate the expression of folate receptor(FR) in primary hepatocellular carci noma and to explore its correlation with clinical and pathological features.Methods Immunohistochemistry was used to detect the expression of FR alpha and beta in primary hepatocellular carcinoma (45 cases),cirrhosis (32 cases) and normal liver tissue (20 cases).And then the relationship between the expression of FR alpha and clinic0pathological features was analyzed.Results The positive expression of FR alpha was detected in 88.9％ (40/45) primary hepatocellular carcinoma,18.8％ (6/32) cirrhosis,and there was no positive expression of FR alpha in normal liver tissue.There was no FR beta expression in primary hepatocellular carcinoma and cirrhosis,only 15％ (3/20) normal liver tissue expressed FR beta.The expression of FR alpha did not correlate with gender and age,but the positive expression of early-mid-term patients was higher than that of the advanced patients.Conclusion FR alpha is presented in most liver tissues of primary hepatocellular carcinoma,which provide basis of early diagnosis and molecular drug target.

ObjectiveTo test the antifungal activity of berberine (BBR) against Candida albicans in vitro. MethodsAccording to the National Committee for Clinical Laboratory Standards (NCCLS) M27-A protocol, broth microdilution test was performed to assess the susceptibility of 30 clinical isolates of Candida albicans to BBR and fluconazole alone or in combination. ResultsThe geometric mean minimum inhibitory concentration (MIC) was 248.18 mg/L and 2.64 mg/L for BBR and fluconazole alone, respectively. When combined with BBR of 320, 160 and 80 mg/L, the geometric mean MIC decreased to 0.03, 0.35 and 1.35 mg/L respectively for fluconazole. Fluconazole and BBR showed synergistic effects in 26.7％ of these isolates including 3 fluconazoleresistant strains, additive effects in 56.7％, indifferent effects in 16.7％, antagonistic effects in none. Conclu sionIn vitro, BBR has antifungal activity against Candida albicans and can enhance the activity of fluconazole against Candida albicans.

Objective To study the significance of anti-cyclic citrullinated peptide (anti-CCP),anti keratin antibody (AKA) and anti-RA33 autoantibodies (RA33)in the diagnosis of elderly-onset rheumatoid arthritis (EORA) and to explore the role of the united detection of anti-CCP, AKA and RA33 in the diagnosis of EORA. Methods The above three kinds of autoantibodies were detected in 69 patients with EORA, 73 patients with polymyalgia rheumatica (PMR) and 65 patients with osteoarthritis (OA). The anti-CCP and RA33 were measured by enzyme-linked immunosorbent assay (ELISA),and AKA was measured by indirect immunofluorescence (IIF). Results In the group of patients with EORA, the sensitivity and specificity of anti-CCP were 55.1% and 94.3%, the sensitivity and specificity of AKA were 31.3% and 91.5%, and the sensitivity and specificity of RA33 were 36.2% and 95.4% respectively, which were significantly higher than those in the groups of patients with PMR and OA. United-detection of anti-CCP, AKA and RA33 reduced the sensitivity,hut increased the specificity (100%) with higher positive predictive value. Conclusions Anti-CCP,AKA and anti-RA33 can emerge in the patients with EORA and the anti-CCP displays higher sensitivity and specificity. United detection of anti-CCP, AKA and RA33 can increase the specificity and positive predictive value (100%) and has high value in the diagnosis of EORA.

Long non-coding RNAs (lncRNA) play important roles in many biological processes.However,compared with other types of RNAs,limited research has been conducted on lncRNA,mostly concerning its relationship with tumor,and there are much fewer studies on its relationship with atherosclerosis.In this article,we summarized the latest research findings in this field,with an emphasis on the importance of IncRNA in atherosclerosis.The value of lncRNA in targeted therapy of atherosclerotic disorders is also discussed.

The changes in shape, structure and function of red blood cells (RBC) after cold storage were observed by using slow cold storage technique. Before and after cold storage, RBC mean corpuscular volume (MCV), RBC fragility (RF), whole blood viscosity (WBV), RBC deformity (RBCD), LFU, SatO2, hematocrit (HCT), RBC recovery rate (RBCRR) and RBC immune function were measured. The result showed that after resuscitation, RBC had vital resistance to hypotonic solution. There was no significant difference in MCV, RBCD and LFU (P>0.05). HCT and WBV were decreased and RBCRR reached 84.1 %(all P<0.01). SatO2 was increased from 30.5 % to 98.2 %. RBC immune function showed no significant difference (P>0.05). It was suggested that quality of RBC didn't change after cold storage and RBC could be cryopreserved for a long time.
