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 analyze the early and long-term results after mitral-aortic valve replacement for rheumatic valvular disease and the determinant factors involved and subsequent therapies.

METHODS1 154 patients receiving combined mitral-aortic valve replacement for rheumatic valvular disease from May 1981 to May 2001 were reviewed. The mean age of the patients was 41.48 +/- 10.00 years. Concomitant valve plasty was performed for associated tricuspid organic or significant functional lesions. Lateral tilting disc or bileaflet valve prostheses were used for replacement. New York Heart Association functional status showed Class III or IV in 91.77% of the patients. Moderate to severe pulmonary hypertension occurred in 29.38% of the patients. The duration of follow-up varied from 8 months to 20 years.

RESULTSThe hospital mortality was decreased from 6.50% to 4.45%. The 5-, 10- and l5-year survival rates were 89.46% +/- 1.35%, 86.50% +/- l.91% and 67.86% +/- 6.16%, respectively. The 5-, 10- and l5-year thromboembolic event free rates were 97.80% +/- 0.74%, 88.31% +/- 2.20% and 94.08% +/- 2.29%, respectively. the 5-, 10- and l5-year anticoagulant related bleeding free rates were 94.80% +/- 1.09%, 89.32% +/- 2.10% and 83.12% +/- 3.57% respectively. Cardiac functional status returned to Class II in 98% patients and to Class III in 2% during follow-up.

CONCLUSIONSBoth left and right ventricular functions may be impaired as a result of rheumatic valvular disease. Tricuspid valve should be explored during surgery and any significant tricuspid annular enlargement and regurgitation showed be corrected in concomitance. Long-acting penicillin regimen is needed for 3 - 5 years for the prevention of rheumatic fever relapse. A low intensity anticoagulant regimen after valve replacement with prothrombin time targeting at 1.5 - 2.0 times is advisable in lessening anticoagulant related bleeding yet optimizing sufficient prevention against thromboembolic complications.

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

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.
