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.

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.

Objective To explore the relationship between size,shape and function of the left atrium appendage (LAA) and its thrombosis in patients with atrial fibrillation (AF) by transesophageal echocardiography (TEE) to provide evidence for clinical risk assessment,prognosis evaluation and treatment guidance.Method Length,diameter,end-diastolic volume (EDV) and ejection velocity (PEV) of LAA were measured in 41 patients with AF,and thrombus in LAA was detected by TEE.Results Thrombus in LAA was detected in seven of 41 patients of AF (17%).No significant difference in size and EDV was found between the patients with and without thrombus,but there was significant difference in PEV between them (P

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 report a case of myelodysplastic syndrome(MDS) with t(1;18)(p31;p11).

METHODSChromosome specimens were prepared by short-term culture of bone marrow cells. Karyotype analysis was made by R banding technique. Chromosome painting was performed using whole chromosome probes 1 and 18.

RESULTSConventional karyotype analysis revealed t(1;18)(p31;p11) in this patient. Chromosome painting analysis confirmed this result.

CONCLUSIONThe translocation of (1;18) was an unusual recurrent chromosome change and was reported on MDS for the first time.

OBJECTIVETo determine the value of fluorescence in situ hybridization (FISH) to the diagnosis of chromosome abnormality in genetic diseases and prenatal diagnosis.

METHODSFISH was performed using appropriate probes, including alpha-satellite DNA probe, chromosome sequence specific probe and whole chromosome painting probe, to examine the blood samples from 36 patients who were suspected of having chromosome abnormality by conventional cytogenetics, and to examine the amniocytes from 45 pregnant women who were in need of prenatal diagnosis.

RESULTSAmong 36 patients, the following karyotypes 45, X; 45, X/46, XX; 45, X/46, Xr(X); 46, X, i(Xq); 47, XXY; 46, XX, t(4;7); 47, XYY; 47, XXX; 47, XXY, inv(7); 46, XY, inv(7); 47, XX, +21 were detected by FISH. Of the fetuses of the 45 pregnant women, two fetuses with chromosomal abnormalities were diagnosed by FISH; the karyotypes were 47, XX, +18 and 46, XY, der(15) t(Y;15) respectively.

CONCLUSIONFISH can precisely and rapidly detect the chromosome abnormalities. It is a complement to the conventional cytogenetics and can be widely used in the diagnosis of genetic diseases and prenatal diagnosis.

OBJECTIVETo investigate the alternation of biological characteristics of residual ear chondrocytes when proliferating in vitro, and study the effects of CDMP-1 on proliferation and differentiation of residual ear chondrocytes.

METHODSResidual ear chondrocytes were cultured in vitro. Then we observed the effect of CDMP-1 on differentiation by immunohistochemistry of collagen type II and dyeing with toluidine blue, investigated proliferation effects of CDMP-1 by method of MIT, and analysis cell cycle changes by flow cytometry.

RESULTSThe quantity of GAG gradually decreased along with the increase of the doubling time of chondrocytes in vitro. The quantity of chondrocytes with positive expression of collagen type II were significantly more in the experimental group used with CDMP-1 than the contrast. And the most efficient concentration of CDMP-1 was 100 ng/ml.

CONCLUSIONSCDMP-1 had a good effect on proliferating and could maintain morphology of the residual ear chondrocytes of microtia cultured in vitro.
