Objective:To investigate the LOH at regions on chromosomal arm 8p22,11p15,17p13 and its relationship with clinicopathological parameters. Methods:Thirty-four paraffin-embedded tumor and corresponding noncancerous tissues were analysed. PCR was used to amplified three microsatellite markers D8S136,D11S988 and TP53 located at these chromosomal regions. PCR products were electrophoresed on 6%polyacrylamide gel and detected using silver staining. The P53, c-erBb-2,PR,ER status were determined by immunohistochemistry. Results:Of the three markers we studied, D8S136 was detected LOH at a frequency of 12 in 34 tumors(35.29%). D11S988 and TP53 were detected LOH at a frequency of 5 in 34 tumors(14.71%). There were no obvious associations between LOH at D11S988、TP53 and clinicopathological parameters, but the tumors with LOH at D8S136 were significant larger than that without LOH(P=0.0049). Conclusion: Invasive ductal carcinoma of the breast has a frequent LOH on chromosome 8p22. The loss or inactivation of putative tumor suppressor genes on 8p22 may contribute to the excessive growth of the tumors.

Objective:To assess effect of age on the characteristic of letf ventricular (LV) twist-displacement loop in health volunteers by velocity vector imaging (VVI) and to provide a new method for LV function evaluation in clinic.
Methods:Atfer obtaining basal and apical LV short-axis images in 98 healthy volunteers (18-75 years old) by 2-dimensional echocardiography, we use VVI sotfware to analysis LV twist motion and radial displacement at each plane off-line. hTe peak LV twist (Ptw), the peak untwist velocity (PutwV), the proportion of untwist in isovolumetric relaxation period (Iutw%) and LV radial displacement (Dis) were measured and calculated. Then we constructed LV twist-displacement loop and compared the characteristic of them among different groups.
Results:Ptw increased gradually with the increase in age. The biggest PutwV was in the group of 30-60 years old. Iutw%increased gradually before 60 years old, then decreased atfer that. Dis was not obviously different among the three groups. hTe characteristic of LV twist-displacement loop was like the configuration of 8. There was a linear relation between twist and displacement during systole, and the slope increased gradually with the increase in age. During early diastole, the relatively small radial expanding displacement displayed with untwisting, resulting in a much steeper twist-displacement relationship curve occurred in each group, which was getting smooth gradually when the radial expanding displacement increased during mid to late diastole.
Conclusions:VVI can be used to effectively and noninvasively assess LV twist-displacement loop with change in age and provide important information for LV function. hTe effect of age must take into account when evaluate the LV function by the twist-displacement loop.

OBJECTIVETo investigate the regulatory effect of Jiangu Granule (JGG) on osteoblast and its effect on bone absorption on the molecular level and from aspect of bone metabolism.

METHODSOsteoporosis model SD rats established by ovariectomy were interfered by drug. Levels of urinary deoxypyridinoline (D-Pyr) and osseous integrin beta1 (Itgbeta1) mRNA expression were detected by ELISA and in situ hybridization, respectively.

RESULTSLevel of urinary D-Pyr increased (P < 0.01) and osseous Itgbeta1 mRNA expression decreased significantly in the model rats. After treatment with JGG for 12 weeks, the D-Pyr levels in them decreased significantly (P < 0.05), while the quantity of osteoblasts and the expression of Itgbeta1 mRNA in bone tissue increased obviously. Conclusion JGG can not only decrease the catabolism of collagen fiber type I in bone matrix, but also promote the osteogenic activity of osteoblast. So, it can improve or reverse the pathological tendency of osteogenesis shortage caused by E2 reduction to play its action in strengthening bone.

Objective To investigate the auxoaction and mechanism of CDllc+DCs on psoriasis. Methods CDllc+ DCs in the psoriasis-like lesions were confirmed by immunofluorescence double staining experiments. The CD1lc+ DCs were subcutaneously injected into the neck skin of transgenic mice without disease. The clinical features were observed and assessed with PASI score every day. The ear and back skin were checked by HE stained. At the same time, the T lymphocyte and DCs of bone marrow, spleen, submandibular lymph nodes and blood were analyzed by flow cytometry, and the T lymphocyte in the skin lesions were analyzed by immunofluorescence. The heart, liver, spleen, lungs and kindey were HE stained. Results In the psoriasis-like lesions, about 90％ CDllc+ cells expressed CDllc. HE test showed that the thickness of the skin layer was significant different between the experimental group (ear: 29±4 μm; back: 25±3 μm) and the control group(ear: 11±2 μm; back: 9±1 μm) (P＜0.01). CD3 + CD4+ T lymphocyte cells in the blood of the experimental mice (17.87％) were decreased significantly (P＜0.01) compared with the control group mice (31.77％). The numbers of Thl and Th17 cells from bone marrow, spleen, submaxillary lymph nodes and blood, as the same as CD1lc+DCs from bone marrow and submaxillary lymph nodes, were decreased in the experimental mice compared with the control group mice (P＜0.01). The number of CD4﹢T cells, CD8+T cells, IL-17a+cells and IFN-γ+cells in the skin lesions from the experimental group all were higher than that from the control group (P＜0.01). And the vessels in the lesions of the experimental group were higher than that in the control group (P＜0.01). Conclusions CD1 lc+CD1 lc+DCs may play an important role in the occurrence and development of psoriasis by increasing the T lymphocyte and the blood vessel in the skins of K14-VEGF transgenic mice.
