Objective To study the rule of gene expression profiles of chronic myelogenous leukemia (CML), and to find new sensitive molecules which express specifically in peripheral blood mononuclear cells(PBMC) of CML patients, in order to further elucidate the potential molecular biological mechanisms leading to CML. Methods The expression of mRNA from PBMC of CML patients was compared with that of normal controls using a cDNA microarray. The bioinformatics analysis was used for every up- or down-regulated gene in CML. The new gene with unknown function and no homology to known genes in the database was confirmed, and electric polymerase chain reaction was conducted for the cloning of its full-length DNA in conjunction with Kozak rule and the exit of polyadenyl signal sequence. Sequence specific primers were designed to amplify the new gene from the mRNA of CML PBMC with the reverse transcription PCR (RT-PCR). Results Many genes commonly up- or down-regulated in CML cells were identified. Of these, we found a novel gene with unknown function with high expression in the patients cells. Its nucleotide sequence and corresponding protein-encoding amino acid had been determined, which contained 1 872nt and 624aa respectively. We named the new gene as human chronic myelogenous leukemia associated protein gene (CMLAP), and logged the sequence of the CMLAP gene into the GenBank with the accession number AY762229. Conclusion CMLAP gene expressed highly in CML PBMC was cloned and identified successfully by combining DNA chip technology and bioinformational technology. The gene was likely to play an important role in the disease and might serve as a molecular marker for CML. The findings will pave the way for the further study of the molecular mechanism of CML.

OBJECTIVE To retrospectively analyze the clinical characteristics of the benign paroxysmal positional vertigo (BPPV) secondary to the sudden deafness (SD) and to explore the possible pathogenetic mechanism, diagnosis and treatment. METHODS 218 cases of the SD in our department were retrospectively analyzed, and 37 patients with primary BPPV during the same period were used as control group. All patients were confirmed by the examination of Dix-Hallpike and the roll check,the primary disease (sudden deafness) of secondary BPPV patients were in line with the Chinese Medical Association diagnostic criteria. RESULTS In all these patients with SD,there were 91 cases with BPPV secondary to the SD. There were 67 cases of BPPV of posterior semicircular canal and 21 cases of BPPV of lateral BPPV semicircular canal. Besides, 3 cases were of multi-semicircular canal affected. All patients with BPPV were diagnosed as the same ears as the SD. The symptoms were alleviated and initial success rate was 68.1%. During 6-22 month follow-ups, total success rate was 100%, and recurrence rate was7.7% (7/91). The hearing recovery of high frequency is worse than that of the low frequency. There were 2 cases of recurrence in lateral BPPV group, 5 cases in posterior BPPV group. All were cured by reposositioning maneuver. All patients with primary and secondary BPPV were cured with Epley maneuver or Barbecue roll maneuver, and the curative effect of them is similar. CONCLUSION The occurrence of BPPV may follow SD,and the majority of BPPV secondary to the SD occurs in the posterior semicircular canal. The canalith repositioning is an effective therapy for secondary BPPV.
