Objective: To observe the inhibitory effects of biotic royal jelly on the ascitic hepatoma cell H22. Methods: Mice bearing H22 tumor were fed on different types of royal jelly: No.1, 2 and 3. Their anti-tumor effects were observed in vivo. The general royal jelly and normal saline were observed as control. Results: Among these biotic royal jelly, the biotic royal jelly No.1 showed obvious tumor-inhibiting and survival-prolonging effects. In addition, it increased the number of WBC and augmented the amount of IL-2 and IFN-γ; the pathological study also indicated the denaturing and necrosis of most tumor cells with nuclei constraining and cell membrane rupturing, and large amount of lymphocytes and plasmacytes infiltrating around the mass. Conclusion: The No.1 biotic royal jelly has obvious anti-tumor effect, and it may take effects by inhibiting or killing tumor cells and improving the immunity of the host.

To explore the value of detection of PML/RARalpha gene rearrangement on bone marrow smears (BMS) by dual-color fluorescence in situ hybridization (D-FISH) for the diagnosis of acute promyelocytic leukemia (APL), the locus-specific probes for PML and RARalpha genes labeled directly and respectively by Spectrum Green and Spectrum Orange and the D-FISH technique were used to detect the PML/RARalpha gene rearrangement on BMS in 27 suspected APL patients. The results were compared with that of conventional cytogentics (CCG) and reverse transcriptase polymerase chain reaction (RT-PCR). The results showed that out of 18 newly diagnosed patients 14 were found having t(15;17) translocation by CCG and PML/RARalpha gene rearrangement were confirmed by BMS-D-FISH and RT-PCR. Thus, their APL diagnosis was determined; out of 4 patients in whom t(15;17) translocation was not detected by CCG, one had positive BMS-D-FISH and RT-PCR results, thus, this case was considered as having a cryptic t(15;17) translocation, three had negative BMS-D-FISH and RT-PCR results, thus, they were diagnosed as having acute myeloid leukemia rather than APL. In 9 cases with remission, one case with partial remission was found having t(15;17) translocation by CCG, and he had positive BMS-D-FISH and RT-PCR results, the other 8 patients (6 cases with normal karyotype and 2 cases without CCG examination) displayed different BMS-D-FISH and RT-PCR results: negative in 6 cases, but positive in 2 cases. The 2 cases were believed that they survived with minimal residual disease (MRD). It is concluded that BMS-D-FISH is a sensitive and reliable method for the detection of PML/RARalpha rearrangement. It is helpful for diagnosing APL and monitoring its MRD, and especially fit to those patients presenting a cryptic translocation or with failed cytogenetics, lacking suitable material for RT-PCR, as well as needing retrospective study.

OBJECTIVETo perform immunophenotyping and molecular genetic analysis for diffuse large B-cell lymphoma (DLBCL), and to explore their correlation and implication for prognosis.

METHODSImmunohistochemical streptavidin peroxidase (SP) method was used to determine the expression of CD10, BCL6 and MUM1 in 59 cases of DLBCL. A Hans algorithm was used to classify DLBCL into germinal center B-cell (GCB) and non-GCB subtypes. Interphase fluorescence in situ hybridization (FISH) assay was performed on paraffin-embedded lymphoma tissue sections to detect translocations and amplifications of BCL6, BCL2 and MYC genes with dual-color break-apart BCL6 probe, dual-color dual-fusion IgH/ BCL2 probe and dual-color break-apart MYC probe, respectively.

RESULTSIn the 59 cases of DLBCL, 28.8% (17/59) belonged to GCB subtype, and 71.2% (42/59) belonged to non-GCB subtype. The incidences of BCL6, BCL2 and MYC gene translocations were 24.1% (14/58), 1.7% (1/59) and 5.3% (3/57), respectively. The incidences of BCL6, BCL2 and MYC gene amplifications were 17.2% (10/58), 22.0% (13/59) and 21.1% (12/57), respectively. BCL6 amplification was not correlated with BCL6 translocation (P=0.424), but was correlated with amplifications of BCL2 and MYC (C=0.405 and 0.403, respectively, P <0.01). The incidence of BCL6 translocation in GCB type was higher than that in non-GCB type, and amplifications of BCL6, BCL2 or MYC were more frequently encountered in non-GCB type, though no statistical significance was detected (P=0.089 and 0.106, respectively). By univariate analysis, immunophenotyping and international prognostic index (IPI) exerted a significant effect on overall survival (OS) (P=0.047 and 0.001, respectively), but to which BCL6 translocation and amplification of the 3 genes were not related (P=0.150 and 0.444, respectively). By multivariate analysis, IPI score was the only independent prognostic factor for OS (RR =3.843, P=0.017).

CONCLUSIONThe GCB subtype of DLBCL is less common in the patient cohort. Common genetic aberrations have included BCL6 translocation and BCL6, BCL2 and MYC amplifications. Amplification of the 3 genes is strongly correlated with each other, and the incidence of BCL2 translocation is low. Immunophenotyping only has minor significance for the prognosis. Genetic aberrations cannot predict the clinical outcome of DLBCL.

OBJECTIVETo explore the efficacy and shortcoming of endovascular therapy with mainly endovascular graft in treating disorders occurring in the thoracic or thoracoabdominal aorta.

METHODSTotal 137 cases with great vessel disorders including dissections, aneurysm, pseudoaneurysm, aortic deceleration injury and coarctation were treated by endovascular technique. The lowest lesion located between the celiac and mesenteric arteries.

RESULTSTwo cases underwent emergent surgery due to acute visceral arterial insufficiency. Seven cases had early endoleaks. After a follow-up of 1 - 43 (average of 11) months, 2 late endoleaks were detected; 5 patients died, 4 of them were due to endograft unrelated diseases, one due to a recurrent multiple aneurysms.

CONCLUSIONEndovascular treatment is relatively safe and effective for treating high risky patients with lesions occurring in the great vessels and seems to have a prospective future, although the device needs to be further improved and the long-term efficacy should be confirmed.

OBJECTIVETo report a rare variant of t(15;17), ins(17;15)(q21;q14q22) in an acute promyelocytic leukemia (APL) patient and the results of cytogenetic and molecular genetic studies.

METHODSChromosomes were prepared after 24 hours culture of bone marrow cells and peripheral blood cells. R-banding technique was used to analyze karyotypes. Chromosome painting analysis was performed using whole chromosome paints for chromosomes 15 and 17. PML-RAR alpha and RAR alpha-PML fusion transcripts were detected by reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSKaryotypic analysis using both specimens from bone marrow and peripheral blood leukemic cells revealed 15q- and 17q+. Chromosome painting analysis confirmed that the karyotypic abnormality was ins(17;15). PML-RAR alpha fusion transcript (S type) was detected by RT-PCR, while RAR alpha-PML fusion transcript was not detected.

CONCLUSIONChromosome painting and RT-PCR are reliable methods for characterization of the insertion involving chromosomes 15 and 17 in APL patients.

OBJECTIVETo explore the value of dual-color fluorescence in situ hybridization (D-FISH) in the detection of inv(16) in acute myeloid leukemia (AML).

METHODSEleven AML patients were investigated by D-FISH with two-color break apart probe for MYH11 labeled directly by fluorescein isocyanate (FITC) and a Texas Red. The results were associated or compared with those of cell morphology, cytogenetics, single color fluorescence in situ hybridization (FISH) and reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSFour cases (M4Eo three cases, M2a one case) had inv(16), of which one had trisomy 22 in addition to inv(16), while the other seven cases had no inv(16), of which, five cases (M4Eo three cases, M4 two cases)had a normal karyotype, one (M2a) had 5p+ and trisomy 22, one (M4Eo) had a translocation t(9;22) on G-banded karyotypic analysis. All 11 cases of AML were positive for the rearrangement of inv(16) detected by D-FISH. The average positive cell rate for these 11 AML patients was 93.45% (range 86.6%-98.7%). Of them, four had a minimal deletion of 16p13 in addition to inv(16). The results of D-FISH coincided with those of RT-PCR or single color FISH.

CONCLUSIOND-FISH is a powerful tool for the detection of inv(16) due to its sensitivity and specificity. For raising the detecting rate of inv(16), it is necessary to screen inv(16) rearrangement by D-FISH in all M4- and M2-AML cases or the cases with trisomy 22, no matter whether they are accompanied by bone marrow eosinophilia.
