OBJECTIVETo study the clinicopathological characteristics of papillary cystadenoma of the epididymis.

METHODSUsing routine pathology and immunohistochemistry, we observed the surgically obtained samples from 2 cases of papillary cystadenoma of the epididymis, analyzed their pathological features and clinical presentations, and reviewed the related literature.

RESULTSThe 2 patients were both adult males. The tumors typically manifested as painless swelling in the epididymis, with occasionally dull pain and tenesmus in 1 of the cases. Pathologically, the lesions exhibited three morphological features, i. e., dilated ducts and small cysts surrounded by fibrous connective tissue, adenoid papillary hyperplasia into the cysts embraced by fibrovascular stroma, and acidophil substance present in the cysts. Immunohistochemistry showed that the tumors were strongly positive for CK8/18, CK7, and EMA, but negative for CK20, CEA, MC, Calretenin, P53, P63, SMA, VHL, and CD10, with the positive rate of Ki-67 <1%. Follow-up visits revealed good prognosis in both cases.

CONCLUSIONPapillary cystadenoma of the epididymis is a rare benign tumor in the male urogenital system, which may be accompanied by the VHL syndrome. Surgery is the first choice for its treatment.

OBJECTIVE: To study ApoB gene genetic polymorphism of Han nationality and Mongolian nationality in midwest area of Inner Mongolia. METHODS: Some unrelated individuals of Han nationality and Mongolian nationality in midwest area of Inner Mongolia were selected. Polymerase chain reaction-restriction fragment length polymorphism technology was used to check the presence of Xba I (X+) and EcoR I (E-) sites of rare alleles. The genotype frequency, allelic frequency and population genetics parameters were calculated. RESULTS: The frequencies of Xba I (X+) and EcoR I (E-) rare alleles were 2% and 4.6% in Han population. There was no Xba I (X+) or EcoR I (E-) rare alleles found in Mongolian nationality. CONCLUSION The allelic frequencies of ApoB gene Xba I and EcoR I sites are very different in different races. These sites may be used in identification of ethnicity.

OBJECTIVETo observe the correlation relationship between acupuncture at Dicang (ST 4), Hegu (LI 4) and Houxi (SI 3) on the affected side of peripheral facial paralysis patients and activated areas in brain functional areas and central regulation mechanism of acupuncture at Hegu (LI 4) treatment.

METHODSEighteen cases with left peripheral facial paralysis were randomly divided into a Hegu group, a Dicang group and a Houxi group, 6 cases in each group. They were treated with electroacupuncture at left Dicang (ST 4), Hegu (LI 4) and Houxi (SI 3), respectively, and were examined with fMRI covering the whole brain at the same time. The fMRI data was analyzed by SPM software.

RESULTSIt was found that the left precentral gyrus area and the left postcentral gyrus area were activated when electroacupuncture at left Hegu (LI 4), and the right precentral gyrus area and the bilateral postcentral gyrus area were activated when electroacupuncture at left Dicang (ST 4), and there was no activated area at precentral gyrus area and post central gyrus area when electroacupuncture at left Houxi (SI 3).

CONCLUSIONThe sensory importation information from Hegu (LI 4) and Dicang (ST 4) can converge and coincide in the brain and may influence each other.

OBJECTIVETo compare the effect of Sodium Morrhuate on ECV-304 between its lipo- and normal preparation.

METHODSThe ECV-304 cell line was supplemented with Sodium Morrhuate and lipo-Sodium Morrhuate in order, and the result on morphology (microscope, Giemsa Staining and electron microscope), cell activity (MTT), and flow cytometer between the two preparation were compared.

RESULTSIn normal preparation group, cell's edema occurred. Chromatin was like catkins. Tumefaction and degeneration of mitochondrion and endoplasmic reticulum appeared. In lipo-Sodium Morrhuate group, the membrane was creased and processus appeared. Chromatin aggregates to the membrane of nucleus was like crescent, and then broken. The apoptotic body was formed. MTT changes showed that the curve of the normal preparation group was steep and the change time was short relatively, which cues the vital cells decreased sharply. The curve of lipo-Sodium Morrhuate group was gentle and the change time was long relatively, which cues the vital cells decreased slowly. The flow cytometer showed that typical apoptosis peak appeared.

CONCLUSIONThe normal preparation group shows an acute toxic effect on ECV-304 cell line, which result in a necrosis course, while lipo-Sodium Morrhuate shows a gradual releasing process, which may indicate a apoptosis course.

OBJECTIVETo evaluate the effect of lipo-sodium morrhuate on ECV-304 cell line.

METHODSThe effect lipo-sodium morrhuate was evaluated by toxicology trial (MTT), electron microscope, DNA electrophoresis and flow cytometer.

RESULTSThe toxicology results showed, that the number of vital cells in lipo-sodium morrhuate group decreased slowly. The electron microscope exhibited apoptosis in the lipo-sodium morrhuate group. And there were typical DNA ladder in DNA electrophoresis and typical apoptosis peak in flow cytometer. The apoptosis rate was 22.23%.

CONCLUSIONSUnlike the normal preparation of sodium morrhuate, lipo-sodium morrhuate could induce apoptosis of ECV-304 cell line.

OBJECTIVETo study aberrant expression of cell cycle control genes in patients with myelodysplastic syndromes (MDS).

METHODSReverse transcription polymerase chain reaction (RT-PCR) was used to investigate the expression of cell cycle control genes (cyclin D2, cyclin D3, cyclin A1, cyclin E, CDK2, CDK4, CDK6, p21, p27, p57, Rb and E2F1) in bone marrow mononuclear cells (BMMNCs) from 29 normal control, 27 MDS and 19 de novo acute myeloid leukemia (AML).

RESULTSThe expression levels of cyclin D3 (0.65 +/- 0.17, P < 0.05) and cyclin A1 (0.48 +/- 0.04, P < 0.05) in MDS were higher than those in normal control and significantly lower than those in AML. The expression rates and levels of cyclin D2 (40.7% and 0.78 +/- 0.21) and cyclin E (51.9% and 0.52 +/- 0.10) in MDS were statistically higher than those in normal control and AML. The expression level of CDK2 in MDS (0.66 +/- 0.19, P < 0.01) was higher than that in normal control (0.42 +/- 0.04) and the expression rate of CDK6 in MDS (25.9%) higher than in normal control (3.4%, P < 0.05). There was no significant difference of the expression rates and levels of CDK4 in MDS, AML and normal control. The expression rates and levels of p21 (77.8% and 1.18 +/- 0.21) and p27 (48.1% and 1.14 +/- 0.40) in MDS were statistically higher than those in normal control and AML. The expression level of p57 in MDS (0.69 +/- 0.06) was higher than that (0.53 +/- 0.05, P < 0.01) in normal control but lower than in AML (0.96 +/- 0.16, P < 0.01). The expression rate (55.6%) and level (0.85 +/- 0.17) of Rb in MDS were significantly higher than those in normal control and AML. The expression rate (7.4%) and level (0.39 +/- 0.04) of E2F1 in MDS were comparable to those in normal control but lower than those in AML.

CONCLUSIONMDS clones have aberrant mechanism of cell cycle control: high expressions of cyclin family members, CDK2 and CDK6 may lead to high proliferation; high expression of p21 and p27 may cause the G1 phase arrest.

OBJECTIVETo evaluate the quantitative and functional changes of T helper (Th) cell subsets in the bone marrow of severe aplastic anemia (SAA) patients and the relationship between these changes and the patients hematopoietic function.

METHODSBy FACS, the quantity and ratio of Th1 and Th2 cells, the percentage of CD3(+)CD8(+) cells in the bone marrow were detected in 24 patients with SAA at active phase, 15 patients with SAA at recovery phase, and 16 normal controls. By radioimmunoassay, the serum levels of TNF-alpha, or IL-4 in 20 SAA patients at active phase, 12 at recovery phase and 16 normal controls were measured. The relationships between CD3(+)CD8(+) cells, TNF-alpha and Ret, ANC; and between Th1 cells and CD3(+)CD8(+) cells, TNF-alpha or Ret, ANC; between IL-4, balance of Th1/Th2 and Ret, ANC were evaluated.

RESULTSThe percentages of Th1 and Th2 cells, and ratio of Th1/Th2 in bone marrow of SAA patients at active phase were (4.87 +/- 2.64)%, (0.41 +/- 0.26)% and 21.22 +/- 5.07, respectively, being higher than those of normal controls [(0.42 +/- 0.30)% (P < 0.01), (0.24 +/- 0.17)% (P < 0.05) and (1.57 +/- 0.93) (P < 0.01), respectively] and all of them reduced to normal levels of SAA at recovery phase (P > 0.05). The percentage of CD3(+)CD8(+) cells significantly decreased from (32.32 +/- 8.69)% at active phase to (13.76 +/- 2.96)% at recovery phase (P < 0.01). The serum levels of TNF-alpha and IL-4 at active phase was (4.29 +/- 3.15) microg/L and (1.24 +/- 0.73) microg/L, respectively, being higher than those of normal controls (1.21 +/- 1.16) microg/L, (1.18 +/- 0.97) microg/L, but only the difference of TNF-alpha was statistically significant (P < 0.01). In recovery SAA patients, the serum levels of TNF-alpha significantly decreased to (1.46 +/- 1.41) microg/L (P < 0.01), and the levels of IL-4 increased markedly to (3.05 +/- 1.94) microg/L. The CD3(+)CD8(+) cells and TNF-alpha of patients negatively correlated with Ret (P < 0.05; P < 0.05) and ANC (P < 0.05; P < 0.05), Th1 cells correlated with CD3(+)CD8(+) cells and TNF-alpha positively (P < 0.01; P < 0.05), the Ret and ANC negatively (P < 0.01; P < 0.01), IL-4 and the balance of Th1/Th2 positively correlated with Ret and ANC (P < 0.05, P < 0.01; P < 0.01, P < 0.01).

CONCLUSIONThe bone marrow failure in SAA might be caused not only by the increase of Th1 cells, Th1 type effector cells and cytokines, but also by insufficient compensation of Th2 cells and Th2 type cytokines, which shifted the balance of Th1/Th2 favorable to Th1.

OBJECTIVETo measure the subsets of dendritic cells 1 (DC1) in the bone marrow of severe aplastic anemia (SAA) patients and evaluate the relationships between the CD11c+CD83+ cells and Th1 cells, CD3+CD8+ cells or hematopoietic function and explore the role of DC1 in the pathogenesis of SAA.

METHODSBy FACS, the quantities and ratios of CD11c+CD1a+ cells, CD11c+CD83+ cells, Th1 cells, and CD3+CD8+ cells in the bone marrow of SAA patients and normal controls were detected respectively. The relationships between CD3+CD8+ cells and reticulocyte absolute value (Ret) or neutrophil absolute value (ANC), between Th1 cells and CD3+CD8+ cells, Ret or ANC, between CD11c+CD83+ cells, and Th1 cells, CD3+CD8+ cells, Ret or ANC were evaluated.

RESULTSIn normal controls' bone marrow, the percentages of Th1 cells, CD11c+CD1a+ cells, CD11c+CD83+ cells and the ratio of CD11c+CD83+/CD11c+CD1a+ were (0.42 +/- 0.30)%, (0.38 +/- 0.29)%, (0.37 +/- 0.32)% and 1.07 +/- 0.10, respectively. In untreated SAA patients, they were (4.87 +/- 0.54)%, (1.73 +/- 0.24)%, (3.38 +/- 0.56)% and 2.21 +/- 0.32 respectively, which were higher than that in normal controls (P < 0.01). In recovering SAA patients, the percentages of Th1 cells, CD11c+CD1a+ cells and CD11c+CD83+ cells decreased significantly to (0.53 +/- 0.22)%, (0.61 +/- 0.23)%, (0.65 +/- 0.22)%, respectively (P < 0.01). The ratio of CD11c+CD83+/CD11c+ CD1a+ in recovering SAA patients decreased to 1.37 +/- 0.25, which was similar to that in normal controls (P > 0.05). The percentage of CD3+CD8+ cells in untreated SAA patients was (32.32 +/- 10.22)%, and in recovering SAA patients decreased to (13.67 +/- 5.24)% (P < 0.01). The percentage of CD3+CD8+ cells in SAA patients was negatively correlated with their Ret and ANC (P < 0.05), while their Th1 cell percentages were positively correlated with their CD3+CD8+ cells (P < 0.01), and negatively correlated with their Ret and ANC (P < 0.01). SAA patient's CD11c+CD83+ cell percentages were positively correlated with their Th1 cell and CD3+CD8 cells (P < 0.01, P < 0.05), but negatively with their Ret and ANC (P < 0.01).

CONCLUSIONBoth immature DC1 and activated DC1 increased in the bone marrow of SAA patients, and the balance of DC1 subsets shifted from stable form to active one, which might promote Th0 cells to polarize to Th1 cells, and cause the over-function of T lymphocytes and hematopoiesis failure in SAA.

OBJECTIVETo investigate the role of the burden of abnormal hematopoietic clone in the development of myelodysplastic syndromes (MDS).

METHODSThe ratio of the bone marrow cells with abnormal chromosomes to the total counted bone marrow cells was regarded as the index of MDS clone burden. The disease severity related parameters including white blood cell count, hemoglobin, platelet count, lactate dehydrogenase level, bone marrow blast, myeloid differentiation index, micromegakaryocyte, transfusion, interleukin-2, tumor necrosis factor (TNF), CD4+ and CD8+ T cells of MDS patients were assayed, and the correlations between those parameters and MDS clone burden were also analyzed.

RESULTSThe clone burden of MDS patients was 67.4% +/- 36.2%. MDS clone burden positively correlated with bone marrow blasts (r = 0.483, P < 0.05), negatively with hemoglobin level (r = -0.445, P < 0.05). The number of blasts, hemoglobin, and erythrocytes in high clone burden (> 50%) and low clone burden ( < or = 50%) groups were 7.78% +/- 5.51% and 3.45% +/- 3.34%, 56.06 +/- 14.28 g/L and 76.40 +/- 24.44 g/L, (1.82 +/- 0.48) x 10(12)/L and (2.32 +/- 0.66) x 10(12)/L, respectively (all P < 0.05). CD4+ T lymphocytes of MDS patients and normal controls were (0.274 +/- 0.719) x 10(9)/L and (0.455 +/- 0.206) x 10(9)/L, respectively (P < 0.05). CD8+ T lymphocytes of MDS patients and normal controls were (0.240 +/- 0.150) x 10(9)/L and (0.305 +/- 0.145) x 10(9)/L, respectively. The serum level of interleukin-2 of MDS patients (6.29 +/- 3.58 ng/mL) was significantly higher than normal control (3.11 +/- 1.40 ng/mL, P < 0.05). The serum level of TNF of MDS patients and normal control group were 2.42 +/- 1.79 ng/mL and 1.68 +/- 0.69 ng/mL, respectively. The ratio of CD4 to CD8 was higher in high clone burden MDS patients (1.90 +/- 0.52) than that in low clone burden patients (0.97 +/- 0.44, P < 0.05).

CONCLUSIONThe quantitive clonal karyotype abnormalities and deficient T cell immunity are important parameters for evaluating MDS severity and predicting its progression.
