Objective To analyze the mental health status among Chinese officials for providing the evidence for mental health promotion.Methods Meta -analysis was used.The data were extracted from 1 995 to 201 2 published papers on the mental health of Chinese officials.And the results was compared with the norm established in 2006.Results The scores of SCL -90 scale among the police officials were significantly higher than that of the norm(P <0.05)and the effect fell in the middle effect scope of Cohen(0.2 0.05 ).Conclusion The meta -analysis demonstrates that the mental health of Chinese officials is not optimistic.More attention should be paid to promote the officials'mental health.

OBJECTIVETo investigate the diagnosis and differential diagnosis of extranodal Rosai-Dorfman disease.

METHODSTwo cases of extranodal Rosai-Dorfman disease were studied using hematoxylin-eosin, and immunohistochemical staining, along with a literature review.

RESULTSThe lesions of RDD were characterized by the presence of large histiocytes with emperipolesis, accompanied by infiltration of lymphocytes, plasma cells and other inflammatory cells. The large histiocytes had an abundant cytoplasm, pale to eosinophilic in appearance, positive for S-100 protein staining, with a vesicular nucleus and a small basophilic nucleolus in each cell.

CONCLUSIONSExtranodal Rosai-Dorfman disease is known as an idiopathic proliferative disease of histiocytes with a distinct morphologic feature and is very rare. Differential diagnosis from other types of fibrohistiocytic proliferation lesions is recommended.

OBJECTIVETo compare 3 common sperm counting chambers by the computer-assisted sperm analysis (CASA) system and evaluate their precision in analyzing sperm density and motility.

METHODSWe used latex bead solution at (20 +/- 5) x 10(6)/ml as analogue semen samples and analyzed the samples with Makler, Leja and Microcell counting chambers, 30 times with each chamber. And the average (x +/- s) and the coefficient of variation of sperm density were calculated by the CASA system. Meanwhile 54 semen samples collected from the outpatients analyzed with the 3 sperm counting chambers by the CASA system for the rates of forward movement and motility of the sperm.

RESULTSThe averages of sperm density obtained with Makler, Leja and Microcell chambers were (25.90 +/- 3.97) x 10(6)/ml, (18.74 +/- 1.62) x 10(6)/ml and (20.35 +/- 2.55) x 10(6)/ml, the coefficients of variation were 15.31%, 8.64% and 12.54%, the rates of sperm forward movement were (46.54 +/- 17.09)%, (30.65 +/- 14.88)% and (30.49 +/- 13.21)%, and the rates of sperm motility were (59.75 +/- 16.12)%, (46.76 +/- 14.11)%, (43.11 +/- 14.02)% respectively. There were significant differences in average sperm density among the 3 groups (P < 0.05). The rates of sperm forward movement and motility obtained with the Makler chamber were significantly higher than those achieved with the Leja chamber and Microcell chamber (P < 0.05), but there were no significant differences between the latter two (P > 0.05).

CONCLUSIONThe rates of sperm density obtained with the 3 sperm counting chambers differed significantly. In the analysis of sperm motility, a higher rate can be achieved with the coverslip-pressed chamber than the capillary-drawn chamber.

OBJECTIVETo evaluate the safety and immunogenicity of Canada split influenza virus vaccine.

METHODSCluster samples were by randomly chosen and divided into split vaccination group and homoimported influenza vaccination group.

RESULTSAfter injection, fever-reaction and local reaction rates of 'trial' group were found as 3.69% and 1.75% respectively, but no statistical significance was found when compared with 'control' group. However the antibody positive rates of 'trail' and 'control' groupsappeared statistically significant (H1N1: 96.8% vs. 92.3%, H3N2: 95.8% vs. 90.2%, B: 52.3% vs. 62.3%). For geometric mean titer (GMT) of type H1N1, H3H2 and B antibody, 'trial' group and 'control' group increased 22.4, 16.8, 8.2 and 21.2, 12.5 and 7.4 times respectively. The antibody protective rates of type H1N1, H3N2 and B were 99%, 99% and 53.9% for 'trial' group, and 96.2%, 98.4% and 62.3% for 'control' but with no statistically significant difference.

CONCLUSIONInfluenza split vaccine made in Shire company in Canada was safe and with good immunogenicity.

OBJECTIVETo observe the exercise single photon emission computed tomography (SPECT) myocardial perfusion imaging of patients with myocardial bridge and assess the association between myocardial ischemia and extent of myocardial systolic compression.

METHODSSeventeen patients with myocardial bridge diagnosed by coronary angiogram were included and underwent exercise SPECT myocardial perfusion imaging.

RESULTSAbnormal SPECT perfusion imaging was evidenced in 12 out of 17 patients with myocardial bridge (2 out of 6 patients with systolic compression induced stenosis < 50%, 3 out of 4 patients with systolic compression induced stenosis between 50% - 75% and 7 out of 7 patients with the systolic compression induced stenosis between 75% - 100%).

CONCLUSIONExercise stress SPECT myocardial perfusion imaging could detect myocardial ischemia in patients with myocardial bridge and abnormal perfusion is positively related to the extent of systolic compression induced stenosis.

OBJECTIVETo research the maturation regulation of dendritic cells (DCs) pulsed with hepatocellular carcinoma (HCC) cell soluble antigens.

METHODSBCG HSP 70 was purified by SDS-PAGE electrophoresis and its biological activity was determined with ELISA. Phenotypes of DCs pulsed with antigens or with both antigens and BCG HSP 70 were analysed with flow cytometry. MTT assay was used to estimate the proliferation of self lymphocytes and the mixed lymphocyte reaction (MLR) of BCG HSP 70 primed DCs.

RESULTSThe characteristics of DCs had changed after loaded with soluble antigens of HCC. There were about 10% DCs which had lost their specific markers. The expression levels of CD54, CD83, CD86 molecules and the stimulatory ability in allogeneic MLR decreased. However, after being activated by BCG HSP 70, the DCs pulsed with antigens could keep their special markers and the expression levels of CD54, CD83, CD86 molecules increased too. The stimulatory abilities in allogeneic MLR and proliferation of self lymphocytes also improved.

CONCLUSIONThis study shows that BCG HSP 70 can induce DCs pulsed with antigens maturation and improve their antigen-presenting ability, which may be a useful maturation inducer for dendritic cells.

Objective To prospectively evaluate whether DWI with mSENSE(mSENSE-DW1)can help to improve image quality and affect the calculation of lesion's ADC,compared with DWI with conventional phase encoding(conventional DWI)in patients with small HCC lesions.Methods Thirty-two patients with 47 small HCC lesions underwent single-shot spin-echo echo-planar.(SE-EPI)DWI with conventional phase encoding and mSENSE.Three b values of 300,500 and 800 s/mm~2 were used.Image quality and CNR between conventional DWI and mSENSE-DWI group were compared with different b value. Lesion's ADC were also calculated and compared.Matched-pairs Wilcoxon signed rank test and Friedman test were used to test statistical significance.Results The image quality was assessed with a five-point scale.For conventional DWI group,image quality score of 2 was assigned in 5 cases,score of 3 in 24 cases, score of 4 in remaining 3 eases with b=300 s/mm~2,score of 2 in 9 eases,score of 3 in 22 cases,score of 4 in remainingl cases with b=500 s/mm~2,score of 1 in 2 cases,score of 2 in 24 cases,score of 3 in remaining 6 cases with b=800 s/mm~2.For mSENSE-DWI group,image quality score of 3 was assigned in 4 cases,score of 4 in 25 cases,score of 5 in 3 eases with b=300 s/mm~2,score of 3 in 10 cases,score of 4 in 20 cases,score of 5 in remaining 2 cases with b=500 s/mm~2,score of 2 in 7 cases,score of 3 in 23 eases, score of 4 in remaining 2 cases with b=800 s/mm~2.Higher image quality scores were achieved at mSENSE- DWI group than conventional DWI group(Z=-5.578,-5.488,-4.796 respectively,P
