Objective To investigate the correlation between epicardial fat thickness (EAT) and the risk factors of coronary artery disease (CAD) as well as the severity of coronary lesions with echocardiography,Methods According to the results of coronary angiography,80 patients underwent coronary angiography were divided into coronary heart disease group (CHD group,4 6 cases) and without coronary heart disease group (control group,34cases),and according to coronary artorrythe severity,CHD goup was divided into subgroups of single-vessel disease (24 cases) and multivessel disease subgroup(22 cases).Tho epioardial fat thickness on the free wall of the right ventricle was measured at end-systole from the para-sterna,long-axis vlews.The relationship between EAT and the risk factors of CAD (such as age,gender,hypercholesterolemia,hypertenston,diabetes,smoking,family CAD history) as well as the severity of coronary lesions were analyzed.Results EAT in multivessel disease CAD group [(8.85 ± 1.44)mm] was significantly higher than that in single vessel CAD group[(6.86 ± 1.09) mm] and control group [(4.58 ± 1.12) mm] (all P ＜ 0.01).EAT was significantly related with the risk factors of CAD.Although the risk factors of CAD such as age,blood glucose,blood pressure were adjusted,EAT was still independently associated with CAD (OR:5.394,95 ％ CI:1.700 ～ 17.1 12,P =0.004).Concluslon The level of EAT is significantly correlated with CAD and the severity of coronary lesions.

Objective To analyze the clinical and histopathological features of 100 cases of scrotal Paget's disease. Methods Specimens were collected from 100 outpatients with scrotai Paget's disease evaluated in the Department of Dermatology, Huashan Hospital, Fudan University during the period of 1987-2004. Clincal data as well as findings in the examination with H&E staining, special staining and immunohisto-chemical staining were retrospectively assessed for these cases. Results Three types of tumor cells were observed in these specimens, including typical Paget cells (51 cases), mutinous or signet-ring cells ( 11 cases), small cells ( 18 cases). Mixed types of tumor cells were seen in 20 cases. Paget cells spread in the epidermis in three patterns (sparsely, intensively and classically). Tumor cells could extend down along the epithelium of follicles or sweat glands, ultimately broke through dermal-epidermal junction or the basal membrane of adnexa, and migrated into the dennis. Conclusions Histopathological examination is the most important clue to the diagnosis of scrotal Paget's disease. Histologically, it should he differentiated from superficial spreading malignant melanoma, skin iymphoma, pagetoid squamous cell carcinoma in situ and secondary scrotal Paget's disease.

Objective To investigate the correlation of social capital and professional burnout in nursing staff. Methods Totally 1329nursing staff were recruited from 6 hospitals in China. They were investigated with the social capital scale and nursing personnel professional burnout scale. Results The mean score of social capital was 13.37±1.30;the mean score of 3 Scales of professional burnout was 24.39± 9.98, 6.24 ± 4.78, 23.37 ± 10.12. The 4 Scales scores of social capital were negative correlated with emotional exhaustion scale, the lack of human individual scale(r=-0.564 to-0.211,P<0.05). Besides with trust and security dimension, low sense of achievement were positively correlated with the total score of social capital (r=0.281-0.281, P<0.05). Conclusion Social capital of nursing staff have important effects on nurse's professional burnout. Nursing managers should take effective measures to reduce nurse's professional burnout.

It was found that protooncogene c-fos was over-expressing in SAC-IIB_2 cell strains. Targeting the code 2-7 sequence of c-fos cDNA of mice, we designed and synthesised eighteen mers antisense. sense and nonsense oligodeoxynucleotides(ODN). The results indicated that antisense c-fos ODN could induce SAC- IIB_2 maturative differentiation, inhibit its growth rate, decrease its ability of forming tumor in nude mice and expression of Fos protein, however, antisense ODN has no remarkable effect on cellular dynamics of SAC-IIB2. But sense and nonsense c-fos ODN have no similar effect on SAC-IIB_2 cell strains. The results demonstrated that antisense c-fos oligodeoxynucleotide has inhibition effects on malignant phenotype of mice SRS lymphoma cell.

Objective The experiment was designed to observe the effect of inhaled arsenic trioxide(As2O3)and in combination with inhaled moxa leaf oil on eosinophils(EOS)and lung tissue's morphology in asthmatic guinea pigs, and to explore its mechanism of relieving wheezing. Methods The ovalbumin(OVA)-induced asthmatic guinea pig model was established. Sixty guinea pigs were randomly divided into As2O3 atomization inhalation group B1 As2O3 low dose group:2.0 mg/(kg·d), B2 As2O3 high dose group:4.0 mg/(kg·d), combined treatment group C1 low dose group:2.0 mg/(kg·d)+moxa leaf oil 0.05 ml, C2 high dose group: 4.0 mg/(kg·d)+moxa leaf oil 0.10 ml, saline aerosol inhalation group(group A) asthma model group)and normal control group(group D)according to random permutation table method. After 7 days medicated, the EOS in bronchoalveolar lavage fluid(BALF)were compared. Guinea pig lung, heart, liver and kidney pathological specimens were prepared and the change of the lung tissue's inflammation and heart, liver and kidney tissue were investigated. Lung tissue’s electron microscopy specimens were prepared and the apoptosis of acidophilic cells and repair of alveolar epithelial cells were observed. Results Compared with asthma model group's EOS number[(58.08±19.01)×105], the difference in As2O3 low dose group、As2O3 high dose group、combined treatment low dose group、combined treatment high dose group and normal control group[(26.37±1.12)×105, (11.50±1.61)×105, (14.16±4.88)×105, (5.03±1.66)×105 and(0.35±0.16)×105, respectively] were statistically significant(P<0.01); there was statistical difference between As2O3 low dose group and As2O3 high dose group(P<0.01);There was statistical difference between As2O3 low dose group and combined treatment low dose group(P<0.01);There was statistical difference between As2O3 high dose group and combined treatment high dose group(P<0.05). Compared with combined treatment high dose group, difference in As2O3 low dose group、As2O3 high dose group and combined treatment low dose group was statistically significant(P<0.05). The difference in B1, B2, C1, C2 and D group was statistically significant compared with group A (P<0.01). The difference in B1 and B2, B1 and C1 group was statistically significant (P<0.01). The difference between B2 and C2 group was statistically significant(P<0.05). The difference in C2 group was statistically significant compared with group B1, B2 and C1(P<0.05). Conclusion EOS abnormal apoptosis was an important pathogenesis of bronchial asthma. The mechanism of arsenic trioxide anti-asthma was that arsenic trioxide could reduce acidophil infiltration and promote acidophilic cell apoptosis. The mechanism of moxa leaf oil anti-asthma was it could reduce acidophil infiltration. Smaller doses of the combination of inhaled As2O3 and moxa leaf oil was safe and effective to achieve the effect of relieving wheezing and the combined use had synergy.
