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.

To analyze the pathogenesis, clinical symptoms, misdiagnosis and operation of endometriosis in unusual sites,32 cases of unusual site endometriosis were analyzed. 468% was correctly diagnosed before operation,and 625% was found to have a history of operation.Good prognosis can be achieved by combined treated on the basis of discussing its pathogenesis clarifying its increasing incidence rate,and attaching importance to its malignant tendency.

Objective　To observe the changes of serum soluble interleukin-6 receptor (sIL-6R) and soluble gp130 (sgp130) in patients with pregnancy induced hypertension. Methods　Enzyme linked immunosorbent assay (ELISA) was used to determine serum sIL-6R and sgp130 levels in 40 patients with pregnancy induced hypertension (study group), 20 normal non-pregnant women (control group I) and 20 normal pregnant women (control group II). Results　In study group, sIL-6R was (196.7±12.9) μg/L and sgp130 was (379.4±79.3) μg/L. In control group I, sIL-6R was (174.8±46.2) μg/L and sgp130 was (273.6±28.3) μg/L. In control group II, sIL-6R was (174.4±48.3) μg/L and sgp130 was (254.4±34.7) μg/L. SIL-6R and sgp 130 were higher in study group than those in control groups with significant difference (P<0.01). In study group, the more severe the patients, the higher the sIL-6R and sgp130 levels. There was significant difference (P<0.01). There was no difference in sIL-6R and sgp130 levels between control groups (P>0.05). Conclusions Serum sIL-6R and sgp130 levels are related to the development of pregnancy induced hypertension.

Objective To study the clinical therapeutic effect of Yifumin Capsule in treating type 2 diabetic insulin resistance and its effect on relevance indexes.Methods Two hundred and forty cases of type 2 diabetic insulin resistance with deficiency of qi-yin and stagnation of phlegm and toxin were divided randomly into two groups,120 cases in each group.The treatment group was given orally Yifumin Capsule,and the control group was given orally pioglitazone.The treatment course of the two groups was 12 weeks.Clinical symptoms,blood glucose,blood lipid,CRP,ISI,FINS,HOMA-IR,liver and kidney function were detected respectively.Results Chinese medicine symptoms and signs were all improved.The total effective rate of clinical effect was 88.1% in treatment group and 52.9% in control group.The clinical therapeutic effect of the treatment group was obviously better than the control group.Both groups had a notable seducement in HOMA-IR,FINS,FPG,2 h PG,HbA1c,TG and LDL-C with an obviously improvement in ISI after the treatment.Compared with the control group,the treatment group had a significant decrease in TC and CRP with notable difference.Conclusion Yifumin Capsule can effectively improve the insulin resistance of type 2 diabetic patients.

Objective To study the distribution and correlation of 20 kinds of inorganic elements (Na,Mg,A1,V,Cr,Co,Fe,Ni,Cu,Zn,Mn,As,Se,Cd,Cs,Sr,Ag,Hg,Pb,and U) in Jiawei Xiaoyao Formula (JXF).Methods The levels of 20 inorganic elements in 10 kinds of herbal substances were determined by ICP-MS with microwave digestion for sample preparation,and the results were analyzed with SPSS22.0.Results There were some correlations among the inorganic elements in JXF;Four main factors were selected by principal component analysis (PCA).The PCA results showed that Na,Mg,A1,V,Ni,Cu,Se,Sr,Cs,Mn,Hg,and Fe might be the characteristic elements in JXF;There were Mg,A1,Mn,and Fe elements in 10 herbal drugs,the contents of inorganic elements in herbal drug were different because the medicinal parts were different,and the decreasing order was roots and rhizomes,skin type,all grass,fruit seeds,and fungi.Conclusion Contents of inorganic elements can not only characterize the stability of extraction process,and can provide experimental evidence for the study of traditional Chinese medicine compound compatibility law.

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.
