ABSTRACT
OBJECTIVE@#Through the analysis of coagulation convention and blood routine parameters of sudden hearing loss (SHL) patients, further prove the correlation of sudden deafness and the the inner ear microcirculation, to guide clinical diagnosis and treatment.@*METHOD@#Select 424 patients (448 ears) with sudden deafness in our department to SHL group. According to hearing curve is classified into low intermediate frequency descent group, high frequency drop and full frequency group, and drawing 244 cases in the same period of hospitalization deviated septum, vocal cord polyp patients as control group. All patients' coagulation detection, D-dimer, blood leukocytes, neutrophils and platelet count percentages were analyzed. Then a meaningful factor multivariate Logistic regression analysis was made.@*RESULT@#There was a statistically significant difference between the two groups' prothrombin time, international normalized ratio, activated partial thromboplastin time, thrombin time measurement, fibrinogen, D-dimer, platelet count, white blood cell, neutrophil ratio(P<0.05); Logistic regression analysis showed that the prothrombin, thrombin time measurement, fibrinogen, D-dimer, neutrophil incidence of sudden hearing loss associated risk factors.@*CONCLUSION@#SHL in patients with coagulation dysfunction may be involved in the occurrence of SHL development mechanism, and there is a correlation of the SHL and the dysfunction of inner ear microcirculation.

Objective To explore the molecular and cytogenetic abnormalities in multiple myeloma (MM).Methods The la-boratory data of bone marrow smears were retrospectively analyzed in 61 patients of MM.24 hours short-term culture of bone marrow and R banding technology were performed in 31 patients.Among these patients,10 cases were selected for de-tecting the IgH gene expression by the interval FISH method.Results The proportions of myeloma cells were 0.19~0.94 in bone marrow smears of 61 patients.In 31 patients,25 patients had enough metaphases for analysis,in which 19 cases (71.3%)had abnormal clones,8q24,11q13,13q14 and 17p13 were important structural abnormalities,where 14q32 rear-rangement was the most characteristic abnormal structure,6 patients were detected IgH gene rearrangement.Conclusion Bone marrow smear combined with other laboratory examinations could make the diagnosis of MM,chromosomal abnormali-ties may help to explore the pathogenesis of MM,and provide a theoretical basis for the early diagnosis,treatment and prog-nosis of this disease.
