Objective To evaluate the profile of proliferating T cells and dendritic cells ( DCs ) in the skin infiltrates of patients with mycosis fungoides ( MF) in different stages. Method Paraffin section and immunohistochemisty with monoclonal antibody were used to detect the expression of special antigen per section. Results The numbers of Ki-67+ cells and cutaneous lymphocyte-associated antigen ( CLA+) cells both increased significantly in the skin infiltrates of MF. Most Ki-67+ cells expressed both CLA and CD4 antigen. The number of Ki-67+ cells was significantly higher ( P

AIM: To investigate two single nucleotide polymorphisms (SNP) in the apolipoprotein(a) promoter at positions -418 and -384 and to compare distributing difference of genotype frequencies of single nucleotide among different races and to explore the influencies of them on serum lipid level and their association with coronary heart disease (CHD). METHODS: Using PCR-RFLP (BsgI,BfaI) method, we determined genotypes of these two SNPs in 156 unrelated healthy controls of HanZu Chinese and 56 unrelated CHD patients of HanZu Chinese and 56 unrelated African Blacks, then cloned polymerase chain reaction (PCR) products into T-vector and sequenced it by M13 currency primer, correspondingly. RESULTS: (1) There was no polymorphism at position -418A/A and -384C/C in control group. Only one CHD patient′s genotype determined was -418G/G, other were -418A/A and (-384C/C) in CHD patients. (2) Only two African Blacks′ genotype determined was -418G/G, other were -418A/A and (-384C/C) in African Blacks. (3) However, the Apo(a) promoter sequence was in coincident with the sequence publicized in GenBank and the base at positions -418 was adenine (A) and -384 was cytosine (C). CONCLUSION: The mutation frequencies at position -418 and -384 are low in the Chinese Han Population of Hubei and perhaps no single nucleotide polymorphisms is at two positions. No association with serum lipid levels and CHD is observed. There may be great variabilities to the SNPs in the Apo(a) promoter among different races.

Clinical medicine is a comprehensive discipline integrating natural science and hu-manities and social science. Lemology is closely related with basic medicine and medical microbiology and medical immunology are the basis of lemology. Therefore, in the process of cultivating postgradu-ates of lemology, we should not only should attach importance to the cultivation of basic medical knowl-edge and clinical professional quality, but also pay more attention to the development of the intelligence factors and non-intelligence factors. Meanwhile education on humanity, social sciences and relevant laws and regulations should be enhanced to cultivate doctors' professional quality. Reverse thinking and lateral thinking in the clinical diagnosis should be strengthened to achieve the training objectives of cultivating international medical talents.

Objective To explore the relationship between occupational physical activity and peripheral arterial disease (PAD)assessed by ankle-brachial index (ABI). Methods Data including ABI,occupational physical activity intensity, health history, medication use, blood biochemistry and physical examinations derived from 16 446 subjects from 9 areas throughout China were analyzed. Univariate and multivariate adjusted logistic regression analysis were used for the data analyses. Results Occupational physical activity intensity was classified into 5 levels as jobless, very light, light, moderate and heavy intensity. With the increasing of physical activity intensity, the risk of PAD gradually decreased ( Ptrend <0. 05). In comparison with jobless group, the ORs of PAD for other groups were 0. 65 (95% CI:0. 52,0.82), 0.70 (95% CI:0.56, 0.87), 0.57 (95% CI:0.44, 0.73), 0.65 (95% CI: 0.53, 0.80)respectively. After adjusting for gender, age, smoke, obesity/overweight, the history of hypertension,hypercholesterolemia, diabetes, cardiovascular disease and stroke, the ORs were 1.02 (95% CI: 0. 80,1.31), 0.91 (95% CI:0.72, 1.15), 0. 92(95% CI:0. 70, 1.19), 0.90(95%CI:0.72, 1.12) (Ptrend <0. 05). Conclusion PAD risk reduced in proportion with increasing occupational physical activity.

BACKGROUND:Human amniotic epithelial cells are an important source of cells in regenerative medicine as its multipotentation, but new studies mainly focused on differentiation features and there were little research oneffect of culture in vitro on biological property of amniotic epithelial cells.
OBJECTIVE:To analyze the effects of in vitro culture on growth, cellphenotype and differentiation capacity of human amniotic epithelial cells into cardiomyocyte-like cells, and explore the correlation of primarily cultured human amniotic epithelial cells marker SSEA-4 expression level and the change of biological characteristics of human amniotic epithelial cells.
METHODS:Primarily cultured human amniotic epithelial cells were obtained from amniotic tissues by using the same separation protocol. Human amniotic epithelial cells were cultured in vitro. The proliferation, cellphenotype and the differentiation capacity of human amniotic epithelial cells into cardiomyocyte-like cells were evaluated by means of cellcounting kit-8, flow cytometry and real-time PCR.
RESULTS AND CONCLUSION:The SSEA-4 positive cells in primarily cultured human amniotic epithelial cells from different fetal tissues were between 26.7%-97%, which indicated that there was great individual difference among amniotic tissue samples. Moreover, with passage, the SSEA-4 expression in human amniotic epithelial cells decreased significantly, which did not correlate with the SSEA-4 expression in primarily cultured human amniotic epithelial cells. Results indicated that there was great individual difference in SSEA-4 expression level in primarily cultured human amniotic epithelial cells from different amniotic tissue samples. Thus, it is necessary to set up clinical screening indexes to get samples with higher SSEA-4 expression stably and to control the quality of human amniotic epithelial cells. In addition, during culture period, SSEA-4 expression level was affected by culture conditions. The culture conditions of human amniotic epithelial cells should be optimized to maintain SSEA-4 expression at a high level. In addition, the differentiation capacity of human amniotic epithelial cells into cardiomyocyte-like cells was also affected by individual difference among different samples and culture conditions, which wil be further studied in the future.

Objective To investigate the expression of GOLPH3 in the tumor tissues of patients with gliomas and evaluate its clinical significance. Methods Seventy-six patients with brain gliomas (13 with grade Ⅰ, 27 grade Ⅱ, 25 grade Ⅲ and 11 with glioblastoma) performed surgical excision in our hospitals from July 2008 to December 2009 were chosen and 9 cases of normal brain tissues from patients performed decompression operation resulting from cerebral hernia were selected as the controls in our experiment. RT-PCR and Western-blotting were used to detect the mRNA and protein expressions of GOLPH3. Results The results investigated by RT-PCR and Western-blotting were consistent,revealing that the mRNA and protein expression rate of GOLPH3 in glioma tissues was not significantly different between different grades of tumors (P＞0.05), but their expression value was obviously significant between different grades of tumors and increased in a grade-dependent manner (P＜0.05). And minimal mRNA and protein expressions of GOLPH3 were found in the tissues of controls. The up-regulative protein expression of GOLPH3 was positively correlated to the malignancy-grade of the gliomas (r,=0.961, P=0.000). Conclusion The mRNA and protein expressions of GOLPH3 are noted with positive correlation to the pathological grades of the gliomas, indicating th at GOLPH3 may play an important role in the generation and development of gliomas.

OBJECTIVETo explore the relationship between maternal milk and serum thyroid hormones in patients with thyroid-related diseases.

METHODSSerum and breast milk samples were collected from 56 breastfeeding mothers. Milk and serum free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine(T3), thyroxine (T4), and thyrotrophin (TSH) were determined, and T3/T4 was calculated. Using the serum thyroid hormones as the independent variables and milk thyroid hormones as the dependent variables, we performed linear regression analysis.

RESULTSThe milk FT3, FT4, T3, T4, TSH, and T3/T4 were (2.30 ± 0.82) pg/ml ,(0.45 ± 0.26) ng/dl, (0.35 ± 0.20) ng/ml, (2.96 ± 1.55) Μg/dl, (0.12 ± 0.08) ΜU/ml, and 0.12 ± 0.04, respectively. Milk FT3 (r = 0.778, P = 0.000), T3 (r = 0.603, P = 0.000), T4 (r = 0.485, P = 0.004), and TSH (r = 0.605, P = 0.000) concentrations were positively correlated with those in serum.

CONCLUSIONThyroid hormones are present in human milk and are positively correlated with those in serum.
