OBJECTIVETo analyze the risk factors of hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation for beta-thalassemia in children.
METHODSThe clinical records of 30 children with beta-thalassemia undergoing allogeneic hematopoietic stem cell transplantation between December, 2008 and November, 2009 were analyzed.
RESULTSHemorrhagic cystitis occurred in 8 of the 33 patients with an incidence of 24.24%, including 1 with grade I, 6 with grade II and 1 with grade III hemorrhagic cystitis. The median time of hemorrhagic cystitis onset was 22.9 days (range 6-35 days) and the median duration was 11.9 days(range 3-27 days). Univariate analysis indicated that the different types of transplantation and acute graft-versus-host disease affect the occurrence of hemorrhagic cystitis. The children with Allo-PBSCT had higher incidence than those receiving Allo-PBSCT+Allo-UBT and Allo-BMT (P<0.05). The children at an age >or=6 years had obviously higher incidence of hemorrhagic cystitis than those at younger ages.
CONCLUSIONAge is the major factor that affects the occurrence of hemorrhagic cystitis in children undergoing allogeneic hematopoietic stem cell transplantation for beta-thalassemia.

This study was aimed to investigate the expression characteristics of two transcriptional factors in Ikaros family, Ikaros and Helios isoforms and their mechanism, as well as their correlation with clinical parameters, which play important roles in transcriptional regulation of hematopoiesis. Expression of Ikaros and Helios isoforms in a total of 163 patients with leukemia and correlations between Ikaros and Helios isoforms were analyzed by PCR. The results showed that different expression patters of Ikaros and Helios isoforms existed in leukemia patients, that is, Ikaros isoform (Ik-6) was predominantly expressed in acute lymphoblastic leukemia (ALL) with BCR/ABL fusion gene, while Helios isoform (He-i) was overexpressed in T-cell ALL patients. The results of cloning and sequencing demonstrated that the isoforms of Ikaros and Helios had different genetic alterations. The statistical correlation between these two isoforms not was found in this study, although interaction between Ikaros and Helios has been reported. It is concluded that although Ikaros and Helios belong to the same family with similar structure of zinc fingers, their isoforms have different expression profile, specific genetic alterations, and different clinical relevance in patients with leukemia. The connection and interaction between Ik-6 and He-i needs further research.

This study was aimed to establish the technique of fluorescence immunophenotyping and interphase cytogenetics as a tool for the investigation of neoplasms (FICTION) used to smear of bone marrow, so as to develop a new technique for detection of the molecular cytogenetic abnormalities in multiple myeloma (MM). By using the bone marrow smear as the carrier and the anti-CD138 antibody linked with FITC, direct fluorescence staining was applied to mark plasma cells (PCs) and differences were compared in the proportion of both PCs marked by fluorescence staining and PCs detected in morphology. At the same time, the chromosome 8 centromere probe was used in interphase fluorescence in situ hybridization (I-FISH) for detection of the chromosome 8 abnormalities in PCs marked by fluorescence staining. The results showed that there was no significant difference between the proportions of both PCs marked by fluorescence staining and PCs detected in morphology on smear (p>0.05). 4 out of 9 patients (44%) had the chromosome 8 abnormalities, including 3 cases with -8 (33%) and one case with +8 (11%). It is concluded that the FICTION technique on the basis of bone marrow smear is characterized by convenience, specificity and accuracy. Therefore, it can be used for molecular cytogenetic research in MM.

OBJECTIVETo evaluate postoperative glottic area and vocal quality of three various surgical techniques for treating bilateral vocal cord paralysis, including laser arytenoidectomy (Group A, 24 cases), reinnervation of the posterior cricoarytenoid muscle by phrenic nerve (Group B, 9 cases) and arytenoidectomy accompanying lateral cordopexy by extralaryngeal approach (Woodman's procedure, Group C, 13 cases).
METHODS46 cases suffered from bilateral recurrent laryngeal nerve injury were included in our study. The pre-postoperative glottic measurement and vocal acoustic parameters were analyzed.
RESULTSThe decannulated cases in group A and group B and group C were 22, 8, 13 respectively. The post-operative mean maximal glottic area was (47.2 +/- 7.4) mm2, (78.3 +/- 16.0) mm2, (48.1 +/- 6.5) mm2 respectively. Group B cases glottic area was larger than that of group A and group C (t value were 4.46 and 3.85, P value were 0.000 and 0.001). No significant difference was found between group A and group C (t = 1.68, P = 0.101). After surgery, in group A, 17 cases voice quality was the same compared with that of before surgery, and 7 cases voice quality had become worse; In group B, the voice quality had become better in 5 cases, completely recovered in 1 case, and had not change in 3 cases; In group C, the voice quality had become deteriorated in 10 cases and no change in 3 cases. And in group B, ipsilateral diaphragm paralysis in 9 cases after surgery, whose vital capacity and forced vital capacity had decreased to 72%-84%, 76%-84% of that before the surgery respectively; and the diaphragm mobility had recovered by 35%-76% respectively, while vital capacity and forced vital capacity had become 93%-97%, 91%-98% of that before the surgery. In Group B, all cases' pulmonary function was normal half a year postoperatively.
CONCLUSIONSReinnervation of the posterior cricoarytenoid muscle by phrenic nerve seems to be best procedure with better post-operative voice and larger glottic area. Although the sufficient airway for decannulation can be acquired in Group A and Group C, but most of patients in Group A had pre-operative vocal level and badly abnormal in Group C.

OBJECTIVETo evaluate the clinical significance of the application of fluorescence in situ hybridization (FISH) in detecting chronic myeloid leukemia (CML).
METHODSChromosome preparation was made by using 24-hour culture. FISH technique using dual color dual fusion (DC-DF) BCR/ABL probe was performed in all 158 cases and R-banding was also employed for karyotyping in some patients.
RESULTSAmong the 158 cases, 98 cases were Ph positive, of which 69 cases (70.4%) were typical FISH pattern (1R1G2F), the other 29 cases (29.6%) showed 12 different types of atypical FISH pattern. The most frequent atypical patterns found were 1R1G1F in 7 cases (7.1%), 2R1G1F in 5 cases (5.1%), 1R1G2F and 1R1G3F in 4 cases (4.1%), 2R2G1F in 3 cases (3.1%). Karyotype analysis on 18 CML cases with atypical FISH patterns demonstrated that the atypical FISH patterns were due to variant translocation in 3 cases; the additional third signal was because of a supernumerary Ph chromosome. The karyotyping results did not conform to FISH results in four cases suggesting the conceivable mistakes in karyotyping. The 1R1G1F signal pattern seen in 3 cases with classical t(9;22) resulted from the deletion of derivative chromosome 9. The 1R1G2F signal pattern detected in 40% to 64% of interphase cells of 3 cases without Ph chromosome by conventional cytogenetic analysis suggested a submicroscopic translocation. Three cases treated with Glivec or bone marrow transplantation showed normal karyotypes with a small amount of BCR/ABL positive cells by FISH detection.
CONCLUSIONFISH technique is of great value for the diagnosis of CML and confirmation of variant translocation, occult Ph translocation, derivative chromosome 9 deletion, therapeutic effect of interferon and Glivec as well as detection of minimal residual disease after bone marrow transplantation.
