BACKGROUND: Stromal derived factor-1 (SDF-1) is an efficacious leukocyte chemoattractant, which can attract lymphocytes and mononuclear cells from bloodstream into the site of inflammation. Emodin., an anthraquinone derivative from Radix et Rhizoma Rhei, and baicalein, a flavone from Scutellaria baicalensis Georgi, both have been reported to possess anti-inflammatory activities. The expression pattern of SDF-1 in experimental acute pancreatitis (AP) and the effect of emodin or baicalein on that are not well defined. The present study aimed to investigate the effects of emodin and baicalein on pancreatic myeloperoxidase (MPO) activity (reflecting leukocyte sequestration) and cytokine production, as well as tissue SDF-1 expression in the setting of AP. METHODS: A :rat model of AP was induced by administration (of 5% sodium taurocholate through the biliopancreatic duct. The level of tumor necrosis factor-a (TNF-alpha), interleukin-6 (IL-6) and MPO in the pancreas, and serum amylase were tested by immunohistochemistry, EliSA and chromatometry. The expressions of SDF-1 alpha and SDF-1 beta were detected by real-time PCR, Western blotting, and immunohistochemistry. RESULT: Combination of emodin and baicalein significantly reduced pancreatic TNIP-alpha, IL-6 and MPO, and also inhibited pancreatic SDF-1 expression. CONCLUSIONS: The inhibition of SDF-1 expression by emodin and baicalein might contribute, in part at least, to the amelioration of pancreatic inflammation. The present study also shows benefits of simultaneous treatment of AP.

Background It is generally accepted that spleen plays a complex role in the tumor immunity, which would change in the different periods of cancer. In this study, we investigated the changes in the function of splenic macrophage （Mφ） in different stages of liver cancer induced by diethylnitrosamine （DEN） in rats. The aim was to support the characteristics of ＂two-way＂ and ＂phase＂ of spleen in tumor immunity. Methods The model of pulmonary metastasis of liver cancer was established in forty male SD rats by DEN. In the 8th, 13th and 16th week, 10 rats were randomly chosen and sacrificed, and divided into cirrhosis, liver cancer and pulmonary metastasis groups depending on the pathological result, respectively. The other 10 rats were taken as control group. The Mφ was isolated by anchoring cultivation. The changes in ultrastructure, phagocytosis, cytokine secretion, antigen processing and presenting, and viability of splenic Mφ） were detected by transmission electron microscopy, VybrantTM Phagocytosis Assay, DQ^TM Ovalbumin, and rat TNF-α EliSpot kits. Results Under the electron microscope, the Mφ） in the control group had some pseudopodium-like prominences, and mitochondria, ribosome, rough endoplasmic reticulum, lysosome can be found in the cytoplasm, and phagocytized RBC. In the liver cirrhosis and liver cancer group, Mφ had more prominences, meanwhile much more mitochondria, ribosome, rough endoplasmic reticulum, lysosome can be found in the cytoplasm, especially in the liver cancer group. In the pulmonary metastasis group, the Mφ was swelling, with few organelle. As compared to the control group, the function of splenic Mφ） increased in cirrhosis and cancer groups, but decreased in metastasis group （phagocytosis rate：（84.7±1.9）% （89.5±3.1）%, and （36.0±2.6）% vs （75.6±1.7）%, P〈0.05, P〈0.01; viability：（1.53±0.15）%, （1.56±0.14）%, and （1.12±0.29）% vs （1.48±0.17）%, P 〈0.05, P 〈0.01; TNF-α secretion：（741.0±52.9）%, （1126.2±174.5）%, and （313.8±50.8）% vs （626.6±24.6）%, P

明代建昌地区建置变化很大,有其特殊性。洪武二十五年前主要是行政建置,以当地民族为府州县卫所土官。洪武二十五年后,月鲁帖木儿等土官反明被平定,明王朝废除了行政建置,代以军事建置,增设四川行都司和卫所,驻军达五万多人。四川行都司辖六卫三十二千户所和五个长官司。行都司官员以流官为主,卫所官员有流有土,长官司为土官。明后期万历三年省建昌前卫后,才出现五卫八所。明前期,行都司及卫所、长官司有效地统治着建昌地区。明中期后,由于军民与夷人交往中的不良行为引起边衅,建昌卫土指挥使和邛部长官司土官衰落,原受土官抑制的彝族奴隶制扩张,掠夺劫杀卫所城镇军民,导致卫所萧条,控制范围大大缩小,军士减至五千多,靠从外地调入大批军队才能平定动乱。继之增置营戍,增派数千军士,分五大信地防守,但仍不能有效控制交通沿线,这种情况直到明朝灭亡。

Morphological changes of blood spleen barrier in portal hypertensive spleen

Chinese Medical Journal 2008年第6期121卷 561-565页

作者： li zong-fang ZHANG Shu HUANG Ying XIA Xian-ming li Ai-min PAN Dun ZHANG Wei WANG Juan Department of General Surgery Second Affiliated Hospital School of Medicine Xi'anJiaotong University Xi'an Shaanxi 710004 China Department of Pathology Second Affiliated Hospital School of Medicine Xi'anJiaotong University Xi'an Shaanxi 710004 China

The pathogenesis of hypersplenism and the immune function of the spleen in patients with portal hypertension （PH） remain obscure. This study aimed to evaluate the morphological changes of blood spleen barrier in spleen with hypersplenism due to PH and provide evidence for an in-depth investigation of the immune function of the spleen with hypersplenism and the mechanism of hypersplenism. Methods Spleen samples from 12 portal hypertensive patients and 4 patients with traumatic ruptures of spleen were examined. The samples of spleen were made into pathological sections, stained with Masson trichrome stain, Gomori stain, and CD68, CD34 immunohistochemistry, and were examined microscopically for the changes in the distribution of collagen fibers, reticular fibers, macrophages, and vascular endothelial cells. The changes in ultrastructure of macrophages and endothelial cells in marginal zone were also evaluated by transmission electron microscopy. Results As compared to the normal spleen, the density of macrophage in the PH spleen was decreased, but the macrophages were mainly located in the marginal zone and distributed around the splenic corpuscle, with many villi and pseudopodium-like protrusion on the cell surface. The accrementition of collagen fibers was obvious around the splenic corpuscle and central artery. The increased reticulate fibers encircled the splenic corpuscle with more connection between the fibers. The vascular endothelial cells were in diffused distribution, without any regionality in PH spleen, but the vessel with enlarged lumina increased in red pulp. Conclusions The morphological changes of the blood spleen barrier can be one of the pathological fundaments for the abnormality of the immune function and the increased destruction of blood cells located in the spleens of patients with PH However. this still entails clarification.

Background Chinese medicine plays an important role in hepatoprotective treatment. This study was conducted to investigate the protective effects of emodin and astragalus polysaccharides （APS） in a rat model of chronic hepatic injury. Methods Chronic hepatic injury was induced by hypodermic injection of an olive oil solution containing 40% carbon tetrachlodde （CCI4） twice a week, in addition to a diet of 79.5% maizena, 20% fat, 0.5% cholesterol, and 10% alcohol in the drinking water ad libitum for 12 weeks. Meanwhile, the rats were exposed to different concentrations of emodin （40 mg·kg^-1·d^-1）, APS （200 mg·kg^-1·d^-1）, combination drug （emodin 40 mg·kg^-1·d^-1 combined with APS 200 mg·kg^-1·d^-1） and colchicine （0.1 mg·kg^-1·d^-1） in parallel by oral gavage （once a day for 12 weeks）. At the end of 12 weeks, blood serum and liver tissue were taken. Serum was collected to determine the levels of total bilirubin （TBIL）, alanine transaminase （ALT）, aspartate transaminose （AST）, and albumin （ALB）. liver and spleen indexes were assayed, followed by the measurements of the liver associated enzyme superoxide dismutase （SOD） and malondialdehyde （MDA）. Histopathological changes were studied using optical microscopy. Results Splenohepatomegalia was alleviated and serum levels of TBIL and ALT were reduced in the groups treated with emodin and APS when compared to the control group. In addition, the ALB level in the APS and combination groups was higher. Similarly, the SOD activity of liver homogenates was significantly higher in the groups treated with emodin and APS, while administration of the herbal derivatives prevented the elevation in MDA levels. Histological analysis showed that the APS and combination groups significantly ameliorated the hepatic injury. Conclusions Co-administration of emodin and APS demonstrated a synergistic action in reducing ALT and restoring ALB in the serum from a rat model of chronic hepatic injury. Emodin and APS may ameliorate the CCI4-
