Major Innovation of the Newly Revised Accounting Law-Reinforcing the Responsibility of the Persons in Charge of Units

With the uninterrupted development of the socialist market economy, there are many phenomena such as mendacious accounting information and false account in the accounting practice. It is an inevitable request for us to amend and improve the Accounting Law, so as to make it reflecting the new content and playing a significant role in accounting work. In this paper, after a thorough discussion of the nature, background and characteristics of the newly revised Accounting Law, a great innovation of the law that laying the primary accounting obligation on the persons in charge of unit is pointed out and its rationality, function and duty are summarized and analyzed.

新疆维吾尔自治区策勒县绿洲一沙漠过渡带小气候特征

利用HOBO小气候观测仪,在2010年7月23日至8月24日对新疆策勒绿洲—沙漠过渡带的柽柳群落、柽柳—骆驼刺—花花柴群落、骆驼刺群落3个典型天然植物群落的风速、气温、空气相对湿度、光合有效辐射进行了同步观测,分析了它们的小气候特征的差异,初步探讨了产生这些差异的原因。结果表明,策勒绿洲—沙漠过渡带的植被具有独特的小气候作用,植被覆盖度越大,风速越小,气温越低,相对湿度越高。相比植被覆盖度仅3%的柽柳群落,柽柳—骆驼刺—花花柴群落（覆盖度27%）和骆驼刺群落（覆盖度67%）在观测期内0.5,1,2,4,8和10m处风速平均减小了32%,47%,近地表0.5m风速减少的最多,分别为57%,87%;2m处气温的平均值分别减少了0.32,1.02℃;2m处空气相对湿度的平均值分别增加2.33%,7.67%;策勒绿洲—沙漠过渡带柽柳群落、柽柳—骆驼刺—花花柴群落和骆驼刺群落的光合有效辐射差异不明显;阴天和沙尘暴天气光合有效辐射比晴天分别减少40%,60%。     

利用~（15）N自然丰度法区分有机和常规生产的作物

应用15N自然丰度法区分有机和常规生产作物,是近年来国内外氮同位素技术应用研究的热点之一。由于化学合成氮肥和有机肥δ15N的不同,作物产品中相应的δ15N也不同,因此利用作物δ15N判断肥料类型就成为可能。影响作物δ15N的因素,除氮肥类型外,还包括作物的类型、生长阶段、部位、大气沉降、水分、pH以及土地利用方式等。在...     

水貂EGF基因SNPS与皮张长度的相关性试验

以水貂的表皮生长因子基因(EGF)作为候选基因,采用单链构象多态性和DNA测序的方法检测了EGF基因单核苷酸多态性(SNPs)。针对该群体的特点建立合适的统计分析模型,并进行了EGF基因多态性与皮长性状的关联分析。结果表明,EGF基因对水貂的皮张长度有一定影响。BB基因型个体与AA基因型个体之间有一定的差异(P<0.05)。CD基因型个体皮长平均要高于CC和DD基因型,且与CC型个体差异显著(P<0.05),与DD型差异不显著(P>0.05)。统计各基因型之间的组合给水貂皮长带来的影响时,发现多数组合基因型对所检测的水貂皮长有显著影响(P<0.05)。

以中国草原红牛、西门塔尔牛、利木赞牛、天一冈山黑牛为试验对象,利用PCR-SSCP结合测序的方法进行SNPs检测,并采用SPSS软件分析CAPN3基因的遗传多态性与肉质性状的关系。结果表明,仅在草原红牛及天一冈山黑牛中发现第46 414处（NC_007308）发生G→T的突变,且发生G→T突变的位点所对应不同基因型的个体,其大理石花纹、失水率、滴水损失和剪切力这些肉质性状存在显著差异,而西门塔尔牛和利木赞牛中未发现此突变。     

Homing and engraftment of allogeneic bone marrow cells in a sensitized mouse model

AIM: To investigate homing and engraftment of allogeneic bone marrow cells (BMCs) in a sensitized mouse model.METHODS: Sensitized BALB/c mice were established by allogeneic splenocytes transfusion. Normal BALB/c mice were used as non-sensitized controls. After 8 Gy of irradiation, the sensitized or non-sensitized mice received 1×10⁷ BMCs from C57BL/6 donor intravenously. A homing assay was also performed by labeling the donor cells with the cell tracker CFSE. Cell suspensions from different tissues were analyzed at different time points (2 h, 12 h and 48 h after transplantation). The survivals were assessed after transplantation, and hematopoietic recovery was monitored. BMCs from recipients were labeled with H-2D^b and the percentage of donor cells was calculated.RESULTS: BMCs labeled with CFSE was suitable for homing study in vivo. Compared with the non-sensitized recipients, the homing assay showed allogeneic BMCs significantly decreased in peripheral blood, spleen and femur of sensitized recipients. Long-term survival was observed in non-sensitized recipients after transplantation by engraftment study, and hematopoiesis recovered rapidly along with time. However, all the sensitized recipients died within 2 weeks after transplantation with a median of 13 days, and hematopoiesis decreased along with time. Severn days after-transplantation, the percentages of allogeneic BMCs in non-sensitized and sensitized recipients were (48.07±4.70) % and (0.77±0.11)% ,respectively, with statistically significant difference (P<0.01).CONCLUSION: Allogeneic BMCs are depleted in spleen and femur of sensitized recipients, and could not engraft in the sensitized recipients.
