Objective To study the expression and significance of CD10, SMA, P63 on human breast myoepithelial cells. Methods SP immunohistochemical method was used to examine the expression of CD10, SMA, P63 on human breast myoepithelial cells from 68 breast diseases samples, including breast fibroadenoma, breast fibroadenesis, breast atypical ductal hyperplasias, ductal carcinomas in situ and breast invasive carcinomas. Results 2 +/3 + circumferential CD10, SMA and P63 staining of MEC was seen in 10 patients with breast fibroadenoma, breast fibroadenoma and 13 patients with atypical ductal hyperplasias. In an analysis of total ducts by 15 patients with breast ductal carcinomas in situ, 3 + circumfenrential staining was seen in 92 of 384 ducts(23.96%) stained for CD10 versus 185 of 384 ducts (48. 18%) stained for SMA and 80 of 384 ducts(20. 83%) stained for P63. All differences among percentage positively stained of these three antibodies was significant, p-values was lower 0. 05. MECs were not found with immunohistochemistry in 170 of 384 duets (44. 27%)with anti-CD10,74 of 384 ducts(19.27%) with anti-SMA and 127 of 384 ducts(33.07%) with anti-P63. MECs were not found with CD10,SMA and P63 in 30 patients with breast invasive carcinomas. Conclusion We concluded that CDIO could be another useful marker of breast myoepithelial cells after SMA and P63. It provided more sophisticated information about presence or absence of breast myoepithelial cells in confusing breast lesions.

Objective To analyze the imaging characteristics of pulmonary sclerosing hemangioma(PSH) and to improve the accurate rate of its diagnosis before surgery.Methods Imaging findings in 11 cases pathologically proved sclerosing hemangiomas were retrospectively analyzed in comparison with pathology.Results The imaging findings of PSH mostly were solitary masses with homogeneous density,and with smooth margin in 10 cases and irregular margin in 1 case;1 case with slight calcification and 1 case with air-meniscus sign were found.7 cases were homogeneous enhancement and 4 were heterogeneous enhancement on contrast-enhanced scan.The high and low attenuation areas on CT corresponded with angiomatous and cystic areas respecitvely on pathology.Conclusion Chest roentgenogram and unenhanced CT scan of PSH are not of remarkable characteristics,contrast-enhanced CT scan plays an important role in diagnosis and differential diagnosis of PSH.

Objective To evaluate the accuracy of systolic pressure variation (SPV) in monitoring blood volume in patients.Methods Twenty-two ASA Ⅱ or Ⅲ patients (17 male,5 female),aged 49-79 yr,with body height 153-173 cm,weighing 55-89 kg,scheduled for elective coronary artery bypass grafting under cardiopulmonary bypass,were studied.Stroke volume variation (SVV) was monitored based on the arterial pressure wave and SPV measured based on the invasive arterial pressure wave after changing the title.After the chest was closed,the volume load test was immediately carried out.6％ hydroxyethyl starch 130/0.4 50-80 ml/min was infused via the jugular vein until cardiac index (CI) increased by 10％.HR,mean arterial pressure (MAP),SPV,CI,SVV,stroke volume index (SVI),systemic vascular resistance index (SVRI),central venous pressure (CVP),and pulmonary capillary wedge pressure (PCWP) were recorded in supine position (T1),at 30° head-down tilt before skin incision (T1'),before (T2) and after opening the chest in supine position (T2'),before (T3) and after the volume load test in supine position after closing the chest (T3'),in supine position after skin closure (T4),and at 30° head-down tilt after skin closure (T4').The difference in SPV and SVV (△SPV and △SVV) was calculated.The receiver operator characteristic curve for △SVV and △ SPV in determining blood volume changes was plotted.Results MAP,CVP,PCWP,CI,and SVRI were significantly increased,while SVV and SPV were decreased at T1' compared with those at T1 (P ＜ 0.05).HR was significantly increased,while CVP was decreased at T2' compared with those at T2 (P ＜ 0.05).MAP,CVP,PCWP,and CI were significantly increased,while SVV and SPV were decreased at T3' compared with those at T3 (P ＜ 0.05).MAP,CVP,and PCWP were significantly increased,while SVV and SPV were decreased at T4' compared with those at T4 (P ＜ 0.05).The area under receive operator characteristic curve for △SVV and △SPV in determining blood volume changes was 0.603 and 0.616 respectively,and there was no significant difference (P ＞ 0.05).Conclusion SPV can accurately monitor the blood volume in patients.

Objective:To evaluate angioimmunoblastic T-cell lymphoma(AITL) completely, we gave in-depth investigation of histopathological features, specific immunochemical markers, antigen receptor gene rearrangements and in situ hybridization for Epstein-Barr virus (EBV). Methods: 15 cases of typical AITL displayed effacement of the normal lymph node architecture partially or completely, abundance of arborizing high endothelial vessels, infiltration of polymorphic cells and hyperplastic atypical T lymphocytes with or without clear cytoplasm. Clinical characteristics, histological manifestations, and immunohistochemical staining for CD3, CD20, CD4,CD21, CXCL13, CD10, and BCL6 were analyzed. Polymerase chain reaction for immunoglobulin heavy chain (IgH) and T cell receptor ? (TCR?) rearrangements and in situ hybridization for Epstein-Barr virus encoded RNA (EBER-1) were performed.Results: Histologically, we found eight cases with regressed lymphoid follicles, six with absence of follicles and one with hyperplastic follicles with interfollicular lesions. We also found eight cases displaying aggregation of clear cells, four infiltration of large lymphoid cells, five abundant epithelioid histiocytes. CD20 staining showed hyperplasia of large B cells in four cases. CD21 expression exihibited extrafollicular expansion of follicular dendritic cell meshworks in 11 cases (73.3%), partially with a tendency of perivascular distribution. Positive rate for CXCL13 and CD10 are 73.3% and 6.7% respectively. Monoclonal rearrangements of TCR? were detected in 6/15 (40%) of cases, IgH rearrangements in 7/15 (46.7%), of which five were monoclonal, while two oligoclonal. 8 out of 15 cases (53.3%) contained EBV-positive cells. Among the four cases with large B cell proliferation, three were EBV-positive. Conclusion: AITL display great complexity and diversity clinicopathologically. Only when we recognize such diversity, can we reasonably apply and properly evaluate immunochemical markers and molecular techniques, and thus give a correct diagnosis.

Objective To construct the RNA interference (RNAi) eukaryotic expression vectors of galectin-1, and establish the LST-R1 cell lines stably transfected by RNAi vectors. Methods Two pairs of small interfering RNAs (siRNA) targeting to galectin-1 mRNA (GenBank: NM002305) were designed. The corresponding single-strand short hairpin interfering RNAs (shRNA), containing BamH Ⅰ, Hind Ⅲ sites and a 9nt hairpin structure, was synthesized and annealed. The annealed product and the linear eukaryotic expression plasmid pSuperior-puro, which were digested with Bgl Ⅱ and Hind Ⅲ, were ligated by T4 ligase to set up the interfering system. The recombined plasmid was identified with EcoR Ⅰand Hind Ⅲ enzyme digestion and sequencing, and co-transfected to LST-R1 cells with pcDNA6/TR with Lipofectamine2000. Positive clones were selected with 0.8?g/ml puromycin. After incubated with 4?g/ml tetracyclin for 48 hours, RT-PCR, Western blotting and immunochemistry were employed to determine galectin-1 mRNA and protein levels. Results Sequencing results suggested that the nucleotide sequence and read frame of RNAi eukaryotic exprssion vector of galectin-1, p-shRNA1 and p-shRNA2 were perfect. Stably transfected LST-R1 cell lines of p-shRNA1-LST and p-shRNA2-LST were established. The relative values of galectin-1 expression in LST-R1 cells, p-shRNA1-LST cells, p-shRNA2-LST cells and p-LST cells by RT-PCR were 0.616, 0.298, 0.373 and 0.641, respectively, and 1.00, 0.07, 0.38 and 0.97 by Western blotting. The p-shRNA1 gave the best interfering effect, which was in conformity with the results of immunochemistry measurement. Conclusions RNAi eukaryotic expression vector of galectin-1 mRNA has been successfully constructed. Establishment of the stably transfected LST-R1 cell lines may lay a foundation to explore the roles of galectin-1 in laterally spreading tumor.
