Objective To explore the influence of ICAM-1 and LFA-1 on the breast cancer metastasis and provide scientific base for studying the molecular mechanism of breast cancer metastasis by observing the expression of ICAM-1(intercellular adhension molecule1) and LFA-1(Lymphocyte function related antigen 1) in different time different metastasis stage of breast cancer. Methods We observed the expression of ICAM-1 and LFA-1 in breast cancer tissue as well as the expression of ICAM-1、LFA-1 and VEGFR-3 in Lymphatic vessel endothelial cell of nearby the breast cancer tissues from the patients of the operation in the defferent stages with the methods of HE staining and immunohistochemistry staining. Results The positive rate of ICAM-1 and LFA-1 expression in cancer cell and cancer nest of breast cancer was increased gradually along with the increase of clinical stages and the occurrence of lymph node metastasis. And the positive rate of ICAM-1、LFA-1 and VEGFR-3 expression in lymphatic vessel endothelial cell of nearby the breast cancer tissues was increased gradually too along with the increase of clinical stages and the occurrence of lymph node metastasis,which has the positive correlation,and it has the positive correlation that the ICAM-1 and LFA-1 expressed in Lymphatic vessel endothelial cell of nearby the breast cancer tissues(P0.05).Conclusion The ICAM-1 and LFA-1 were related with breast cancer lymph metastasis,and the ICAM-1 and LFA-1 promoted breast cancer lymph metastasis through synergism each other.The increase or decrease of ICAM-1 and LFA-1 expression in the breast cancer tissue and lymphatic vessel endothelial cell of nearby the breast cancer tissues could as the data target to display certain instruction function for prevention and treatment of breast cancer lymph metastasis.The Lymphatic vessel quantity of nearby the breast cancer tissues was increased along with tumor progress, which may be related with breast cancer lymph metastasis.VEGFR-3 has the high specificity in the lymphatic vessel endothelial cell expression,and may act as the lymphatic vessel as the lymphatic vessel endothelial cell specific marker.

Spleen-yin theory was the innovation of doctors in Ming Dynasty for Piwei theory of Dongyuan based on the inheritance of nourishing yin theory of Danxi. But because of rise of stomach yin theory, spleen yin theory was ignored gradually. This article revealed the neutralizing therapeutic conception contained in this theory, which was hoped to be applyed into medical practice and to be deepened furtherly.

Objective To explore the therapeutic mechanism of Xiao Chaihu Decoction for endometriosis in rats. Methods The rat models of endometriosis were treated with Xiao Chaihu Decoction, Danazol, and Xiao Chaihu Decoction plus Danazol for 4 weeks,respectively. And then cyclooxygenase-2(COX-2) expression in endometrium and endometriotic tissue was observed by immunohistochemistry method. Results The expression of COX-2 in the endometriotic tissue was lower than that in endometrium in Xiao Chaihu Decoction group and Xiao Chaihu Decoction plus Danazol group, while the results in Danazol group and control group were opposed to those in the above two groups. Conclusion The mechanism of Xiao Chaihu Decoction for rats endometriosis may be related to the decrease of COX-2 expression in ectopic Endometrium, thus reducing the formation of prostaglandins.

Objective To investigate the correlation of plasma lysophosphatidic acid (LPA) and matrix metalloproteinase-9 (MMP-9) with carotid atheromatous plaque stability in patients with cerebral infarction. Methods The duplex uhrasonography and transcranial Doppler-detected microemboli were performed in the carotid arteries of all the 87 patients with cerebral infarction located in arteriae carotis interna system. The patients were divided into the intima thickening group (n=16),unstable plaque group (n=41), stable plaque group (n=21) and non-plaque group (n=9). And there were 27 patients with positive microembolic signal and 60 patients with negative microembolic signal.The plasma levels of LPA and MMP-9 were determined by quantitative determination of inorganic phosphorus and enzyme-linked immunosorbent assay. Results The levels of LPA and MMP-9 were significantly higher in unstable plaque group than in the other three groups (F=49.98 and 106.49,both P<0.01), MMP-9 in intima thickening group and stable plaque group were both higher than in non-plaque group (q=7.04 and 7.51, both P=0. 00). LPA was higher in intima thickening group than in stable plaque group (q=7.37, P=0. 00), and higher in the above two groups than in non-plaque group (both P<0.05). The levels of LPA and MMP-9 were higher in microembolic signal-positive patients than in signal-negative patients (t=42.57 and 16.61, both P=0.00). LPA level was positively correlated with MMP-9 (r=0.22, P<0.05). Conclusions LPA and MMP-9 may serve as a potential risk signal to hint the formation and rupture of unstable carotid atheromatous plaque which may cause ischemic cerebrovascular disease.

The therapeutic management of hepatic portal hypertension in patients with cirrhosis is still a challenge. At present surgical devascularization and shunting play the important roles in treatment of portal hypertension. While some cirrhotic patients can not bear the stress of operation and anesthesia because of inadequat potential hepatic function. So the mortality of operation is very high. With the development of endoscopy,radiological techniques and new materials and equipments, the mini invasive treatments become more important. This review summarizes the current advances of mini invasive treatments of portal hypertension in cirrhosis.
