Prevention of de novo HbV infection by the presence of anti-Hbs in transplanted patients receiving core antibody-positive livers

World Journal of Gastroenterology 2006年第13期12卷 2070-2074页

作者： Rafael barcena Gloria Moraleda Javier Moreno M Dolores Martín Emilio de Vicente Jesús nuo M Luisa Mateos Santos del Campo Department of Gastroenterology Hospital Ramón y Cajal Facultad de MedicinaUniversidad de AlcaláCtra.

AIM： To analyze whether the presence of anti-Hbs in liver transplant recipients is effective in preventing HbV infection. METHODS： Twenty-three patients receiving anti-Hbc positive liver were studied. Nine recipients were anti-Hbc positive as a result of previous HbV infection. Of them, one also received HbV vaccine during the pre-liver transplantation period. Fourteen recipients were anti-Hbs positive due to HbV vaccine administered during the pretransplant period. Liver biopsy was obtained in 10/14 anti-Hbc negative/anti-Hbs positive recipients and in 4/9 anti-Hbc positive recipients. RESULTS： After a mean foUow-up period of 46 months, 1 recipient with protective serum anti-Hbs levels developed de novo HbV infection as a consequence of immune escape HbV mutants. Among the 14 vaccinated anti-Hbc negative/anti-Hbs positive recipients, 1/10 patients with available liver biopsy （10%） had liver HbV-DNA at 13 mo post-liver transplantation without serum viral markers and did not develop de novo HbV *** vaccinated anti-Hbc positive recipient without HbV vaccine response was HbV-DNA positive in serum and liver, viral DNA was continuously negative in the following tests, so a spontaneous seroconversion was diagnosed. CONCLUSION： The presence of anti-Hbs as a result of HbV vaccine or past HbV infection seems to be effective at protecting patients receiving livers from anti-Hbc positive donors. However, the emergence of immune escape HbV mutants, which can evade the anti-Hbs protection, should be considered as a risk of HbV infection.

Mediating effect of dopamine D3 receptors on Jak2 and GAbAAα1 expression in mouse brains induced by cocaine

引用

Chinese Medical Journal 2007年第10期120卷 910-914页

作者： LIU nu-yun ZHANG Lu ZHANG Lin WANG Xiao-ning College of Traditional Chinese Medicine Southern Medical University Guangzhou 510515 China Department of Pathophysiology Key Laboratory of Guangdong Proteome Analysis Key Laboratory for Transcriptomics and Proteomics Ministry of Education Southern Medical University Guangzhou 510515 China Department of Histology and Embryology Southern Medical University Guangzhou 510515 China Laboratory of Molecular Immunology Southern Medical University Guangzhou 510515 China

background Cocaine addiction may involve complex neuroadaptations, including many changes of genes expression. Dopamine D3 receptors play an important role in cocaine addiction; however, its role in cocaine induced gene expression change is poorly understood. To identify the changes in gene expression induced by repeated cocaine exposure through D3 dopamine receptors, we compared the expression of four molecules： Janus kinase 2 （Jak2）, g-aminobutanoic acid receptor subunit alpha 1 （GAbAAα1）, glutamate receptor AMPA3 alpha 3 （GluR 3） and stromal cell derived factor 1 （SDF1）. These four have been implicated in mediating the actions of cocaine in the nucleus accumbens （NAc） and caudoputamen （CPu） in mice after acute and repeated cocaine exposure. Methods For the acute and repeated injections, the mice were divided into four groups： 30 mg/kg cocaine, nafadotride 0.5 mg/kg ＋ cocaine 30 mg/kg, nafadotride 0.5 mg/kg, and saline as the basal group. The expression of Jak2, GAbAAα1, GluR 3 and SDF1 were assayed by Western blot, quantitative real-time RT-PCR and immunohistochemistry. Results Twenty-four hours after seven consecutive days of repeated cocaine exposure, the expression of GAbAAα1 decreased in cocaine group compared with basal line and further decreased in the cocaine ＋ nafadotride group and remained at basal level in the nafadotride group. Similarly, the Jak2 expression decreased in cocaine group compared with base line. However, the levels of Jak2 increased in cocaine ＋ nafadotride group compared with cocaine group, while remained at basal level in nafadotride group. Conclusions GAbAAα1 and Jak2 may be involved in chronic cocaine induced neuroadaptations. D3 dopamine receptors play an important role in the expression of these genes.

Journal of Wuhan University of Technology(Materials Science) 2003年第4期18卷 72-75页

作者：胡曙光 Wuhan University of Technology

The hydration process,hydration product and hydration heat of blended cement paste mixed with mineral admixture and expansive agent at low W/b ratio are studied by XRD,thermo analysis,and calorimetry instrument,and they were compared with those of pure cement *** results show that pure cement and blended cement at low W/b ratio have the same types of hydration products,but their respective amounts of hydration products of various blended cements at same ages and the variation law of the amount of same hydration products with ages are different;The joint effect of tumefaction of gel-ettringite due to water absorption and the expansive pressure on the pore and rift caused by the crystalloid ettringite is the impetus of the volume expansion of cement paste,and the former effect is much greater than the latter one.

崧泽文化时期的经济基础是玉石小商品经济。犁耕促进了集约化农业商品粮生产,用于粮食交易的石权和商品交易计数的陶筹随之出现,陶豆等陶器则可能出于满足商品交换的需要而实现了量产;社会分工的进一步细化催生了艺术家阶层的诞生;核心地区与边缘地区商品生产形成产品和市场的互补。崧泽文化圈及其商品经济贸易圈为手工业和商业精英成为社会上层提供了路径,引发了社会的等级分化,使得长江流域的社会分化即复杂化开始于崧泽文化时期,明显早于其他地区。
