广西隆安县南圩镇亥日市场上的"牛中",是当地牲畜交易的中介人。尽管"牛中"本身并不直接交易牲畜,但他们在当地牲畜交易市场的运作中扮演着十分重要的角色。基于对亥日牲畜市场的调查,文章对于牛中在市场中的社会功能进行了研究。认为牛中是维系南圩亥日牲畜市场交换的重要力量,他们的活动促进了牲畜交易市场与当地社会的整合,而牛中现象的出现也折射出南圩农民在商品交换问题上的风险意识和成本意识。

Objective: Impairment of natural killer(NK) cell activity is an important mechanism of tumor immunoevasion. T-cell immunoglobulin domain and mucin domain-3(Tim-3) is an activation-induced inhibitory molecule, inducing effector lymphocyte exhaustion in chronic viral infection and cancers. However, its function in NK cells in human esophageal cancer remains ***: We prospectively collected peripheral blood and tumor samples from 53 patients with esophageal cancer. Peripheral and tumor-infiltrating NK cells were analyzed for Tim-3, Annexin V, CD69, CD107 a and IFN-g expression by flow cytometry. Quantitative real-time PCR was used to test relative mRNA expression of IFN-g, granzyme B, perforin and NKG2 D in sorted Tim-3+ NK cells and Tim-3-NK cells, respectively. NK cells isolated from healthy donors were treated with recombinant TNF-α to induce Tim-3 expression. Tim-3 and TNF-α mRNA levels in tumor tissues were measured in both humans and mice. Finally, associations between NK cell frequencies with pathological parameters were ***: We observed up-regulation of Tim-3 expression on NK cells from esophageal cancer patients, especially at the tumor site. Furthermore, tumor-infiltrating NK cells with high Tim-3 expression exhibited a phenotype with enhanced dysfunction. In vitro, Tim-3 expression on NK cells isolated from blood of healthy donors can be induced by recombinant TNF-α via NF-κB pathway. In both animal models and patients, the Tim-3 level was positively correlated with TNF-α expression in esophageal cancer tissues. Finally, higher Tim-3 level on tumor-infiltrating NK cells is correlated with big tumor size, nodal status and poor stage in patients with esophageal ***: Taken together, Tim-3 may play a crucial role to induce NK cell dysfunction in tumor microenvironmentand could serve as a potential biomarker for prognosis of esophageal cancer.

Water and nitrogen (N) management are key factors for sustainable pear production in many areas. Effects of integrated N fertilization and irrigation systems, rootstocks, and cultivars on pear (Pyrus communis) mineral nutrition, irrigation water and N consumption, and fruit productivity were investigated on a fine sandy loam soil at Hood River, Oregon from 2005 through 2007. Nitrogen application reduced to 80% of the current broadcast application rate and fertigated in five equal split applications could supply bearing pear trees with adequate N nutrition without reducing soil N reserves. Shifting from the broadcast of dry N fertilizer on soil surface and micro sprinkler irrigation system (BSS) to the split N fertigation and drip irrigation system (FDS) did not affect tree growth, fruit yield, or fruit size of pear. However, FDS produced more Bartlett fruit in color categories of 390 - 417 and 417 - 496 nm than BSS. Irrigation water consumption was reduced by 42.0% to 78.3%, but water use efficiency was enhanced by 51.0% to 264.2% with FDS relative to BSS. Split N fertigation and drip irrigation system may be used as an alternate N fertilization and irrigation system on bearing pear orchards to reduce irrigation water and N consumption in Hood River and other similar areas.

Based on the structure of citation network, the citation paths among papers, and the association strength such as coupling, co-citation and etc. between two papers are defined in this article. We give formulas to quantify the association strength in order to establish citation network model based on the citation path structure. Then, the OPTICS algorithm is brought into the scientific communities found model since it can solve the parameter’s setting problem. This method combines various kinds of path structures together and thus it contains more complete citation network information. Experiments and analysis reveal the reliability and validity of this method.

Detection of abnormal myocardial perfusion is crucial to the prognosis of patients with coronary artery disease(CAD)after they have undergone percutaneous coronary intervention(PCI).The objective of this study is to evaluate the effect of myocardial perfusion by three different methods—intra-coronary myocardial contrast echocardiography(ICMCE),corrected thrombolysis in myocardial infarction frame count(CTFC),and coronary blood flow velocity(BFV)—and to determine the value of these different methods in the evaluation of the effect of myocardial perfusion *** the study sixty-eight patients were divided into four groups based on selective coronary angiography results:group A(normal coronary artery),group B(75%–95%coronary artery stenosis),group C(coronary artery stenosis>95%)and group D(acute total coronary occlusion).The effect of myocardial reperfusion was evaluated using the above mentioned three methods 15 min after ***-MCE was also performed before PCI in group *** quantitative parameters of MCE involved:contrast peak intensity,time to peak intensity and area under the curve,representing myocardial blood volume,reperfusion velocity and myocardial blood flow,*** difference was found in CTFC between the coronary artery stenosis group and the normal *** was slower in group D than in group A(P<0.05).The myocardial blood volume and the myocardial blood flow of the IC-MCE quantitative parameters were markedly lower in group C compared with those in group A(P<0.05),and there were significant differences in the three MCE parameters between group D and group A(P<0.05).For those patients with acute or total occlusion,the levels of myocardial perfusion before and after PCI were similar,as determined by IC-MCE and visually analyzed from 61 segments(P<0.05).Quantitative IC-MCE evaluation of myocardial reperfusion is more accurate than with the other two ***,with qualitative IC-MCE the level of myocardial reperfusion can be viewed di
