A long-term field experiment was established to determine the influence of mineral fertilizer and organic manure on soil fertility. A tract of red soil （Ferralic Cambisol） in Qiyang Red Soil Experimental Station （Qiyang County, Hunan Province, China） was fertilized beginning in 1990 and N20 and CO2 were examined during the maize and wheat growth season of 2007-2008. The study involved five treatments： organic manure （NPKM）, fertilizer NPK （NPK）, fertilizer NP （NP）, fertilizer NK （NK）, and control （CK）. Manured soils had higher crop biomass, organic C, and pH than soils receiving the various mineralized fertilizers indicating that long-term application of manures could efficiently prevent red soil acidification and increase crop productivity. The application of manures and fertilizers at a rate of 300 kg N ha-1 yr-1 obviously increased NzO and CO2 emissions from 0.58 kg N20-N ha-~ yr-~ and 10565 kg C ha-~ yr-~ in the CK treatment soil to 3.0l kg N20-N ha-~ yr-~ and 28 663 kg C ha-~ yr-I in the NPKM treatment. There were also obvious different effects on N20 and CO2 emissions between applying fertilizer and manure. More N20 and CO2 released during the 184-d maize growing season than the 125- d wheat growth season in the manure fertilized soils but not in mineral fertilizer treatments. N20 emission was significantly affected by soil moisture only during the wheat growing season, and CO2 emission was affected by soil temperature only in CK and NP treatment during the wheat and maize growing season. In sum, this study indicates the application of organic manure may be a preferred strategy for maintaining red emissions than treatments only with mineral fertilizer. soil productivity, but may result in greater N20 and CO2

AIM： To assess the effects of obstructive cholestasis on a wider range of gene expression using microarray technology. METHODS： Male C57BI_/6J mice underwent common bile duct ligation （BDl） and were matched with pairfed sham-operated controls. After 7 d, the animals were sacrificed and total RNA was isolated from livers and kidneys. Equal amounts of RNA from each tissue were pooled for each group and hybridized to Affymetrix GeneChip^MG-u74Av2 containing a total of 12488 probe sets. Data analysis was performed using GeneSpring 6.0 software. Northern analysis and immunofluorescence were used for validation. RESulTS： In sham-operated and BDl mice, 44 and 50% of 12488 genes were expressed in livers, whereas 49 and 51% were expressed in kidneys, respectively. Seven days after BDl, 265 liver and 112 kidney genes with GeneOntology annotation were up-regulated and 113 liver and 36 kidney genes were down-regulated in comparison with sham-operated controls. Many genes were commonly regulated in both tissues and metabolism-related genes represented the largest functional group. CONCluSION： Following BDl, microarray analysis reveals a broad range of gene alterations in both liver and kidney.

Background Ring annuloplasty is the standard treatment of ischemic mitral regurgitation (MR), however, it has been associated with some drawbacks. It abolishes normal annular dynamics and freezes the posterior leaflet. In the present study, we evaluated Paneth suture annuloplasty in chronic ischemic MR and both early and mid-term outcomes of the technique on a selected *** The study period was from June 2010 to June 2012. We operated on 21 patients who had the diagnosis of coronary artery disease andMR of grade 3 or 4. The patients had both a coronary artery bypass operation and the mitral semicircular reduction annuloplasty described by Paneth-Burr. The data on the patients were retrospectively collected. Patients were contacted by outpatient clinic controls for mid-term results. Results The male/female ratio was 10/11. The mean age of the patients was 71.0 ±6.4 years. Preoperative and postoperative left ventricular ejection fraction was statistically similar (P = 0.973). Early postoperative MR grade (mean, 0.57 ±0.51) was statistically lower than the preoperative MR grades (mean, 3.38 ±0.50) (P leeding. Two patients had prolonged hospitalization, one for sternal infection and the other for severe chronic obstructive pulmonary disease. No hospital or late postoperative deaths occurred. The mean late postoperative MR grade was 0.66 ±0.97 degrees. One patient had progression of MR in the later follow-up, which was treated by mitral valve replacement. Conclusion Semicircular reduction annuloplasty is an effective, inexpensive and easy surgical annuloplasty technique with lowmortality and morbidity in severe symptomatic ischemic MR.

地质勘探类型是科学地质调查和有效矿产资源评价的基础和前提。矿田是包含几个矿床的成矿空间,单个矿床的勘探类型不一定适用于矿田的地质勘探。文中遵循"成矿作用、地质工作程度和资源经济条件"的思路,探讨矿田勘探类型和分类问题。以地质勘查工作程度(地质调查或勘探报告所遵循的工作精度,即成果图件的比例尺为指标)和资源技术经济条件(各级资源储量的比例,并结合矿山生产规模为指标)为指标,作者建立"地质勘查程度资源经济条件"评价系统。经该系统的综合评价,研究预查矿田(Ⅲ)、普查矿田(Ⅱ)和详查矿田(Ⅰ)的基本地质勘探类型。矿田地质勘探类型的确定,为推动整装勘查区的找矿突破、制定勘查规划和勘探工作的投入提供了可参考的方法和思路。文中选择6个典型矿田,详细展示矿田勘探类型的评价过程和方法。

矿田地质学是研究矿田建造、矿田构造和矿田成矿的学科领域。本文提出矿田的构造岩相分类建议。矿田第一层次的构造岩相分类以成矿地质作用和成矿地质环境为基础,概分为4大类,即沉积矿田或沉积岩相矿田、岩浆矿田或岩浆岩相矿田、变质矿田或变质岩相矿田以及复成型构造蚀变矿田或构造蚀变岩相矿田。考虑矿田成矿构造环境的规模、可识别性和可观测性,本研究以次级岩相建造划分矿田类型:比如在火山岩矿田类型之中,应该具体细分为火山角砾岩相矿田、火山熔结凝灰岩相矿田等类型。初步划分了31类构造岩相矿田:例如,山东淄博湖泊相铝土矿田、德兴陆相次火山热液相斑岩铜矿田、攀枝花基性辉长岩相钒钛磁铁矿田、美国上湖绿片岩相铁矿田、胶东玲珑焦家式黄铁绢英岩相金矿田等。矿田成矿作用和环境及其构造岩相分类,将会推动矿田尺度的地质调查和勘探,推进构造结合建造研究,为矿田地质研究紧密结合找矿预测提供了一个基础分类和研究思路。
