Soil water is the key factor that restricts the restoration of the local ecological systems in the Loess Plateau of China.Studying the effects of vegetation types on soil water and its seasonal variation helps to understand hydrological characteristics and provides insights into the sustainable restoration of vegetation.Therefore,the Caijiachuan watershed was chosen as the research object to investigate the water status of a 0-10 m soil layer under different vegetation types including Pinus tabulaeformis,Robinia pseudoacacia,Platycladus orientalis,apple orchard,natural forestland,farmland and grassland.By comparing the difference between soil water of different land use types and that of grassland during the same period,the seasonal changes of soil water status of different types were judged.The results show that(1)in the 0-10 m soil layer,the largest value of soil water content was in the0.3-0.4 m layer,and the lowest was in the 5.6-5.8 m layer.The depths at which the vegetation cover influenced the soil water were up to 10 m;(2)among summer,fall and spring,the soil water storage wasthe highest in the fall.In addition,the lowest value of relative accumulation was in the fall,which was the period in which the soil water recovered;(3)the soil water in the 0-10 m layer was in a relatively deficient state in the artificial forestlands,apple orchards and native forestlands,while the relative accumulation was in the farmland.In addition,the relative deep soil layers(8-10 m)had more serious deficits in the areas in which P.tabulaeformis,R.pseudoacacia and the apple orchard grew;(4)during the study period,the farmland in the summer had the largest relative accumulation(182.71 mm),and the land under R.pseudoacacia in the fall had the lowest relative deficit(512.20 mm).In the Loess Plateau,vegetation cover will affect the change of deep soil moisture and artificial forest will cause soil water loss in different degrees.

内源性大麻素系统作为维持和平衡人体各项机能的重要生物网络,参与疼痛、情绪、学习记忆等多项生理功能,其中内源性大麻素受体(包括Ⅰ型、Ⅱ型)在疼痛的调控中发挥着重要的作用,也成为针刺镇痛机制研究中的重要靶点。在中枢和外周神经系统中,针刺可以分别激活大麻素Ⅰ型受体和Ⅱ型受体,参与到中枢痛觉信号和相关递质的传导以及外周与疼痛相关的炎性反应中,进而缓解模型动物的痛觉超敏。本文系统总结了上述机制在不同类型动物模型中的作用,以期为针刺镇痛机制研究提供新思路。

The ecosystems of China seas and coasts are undergoing rapid changes under the strong influences of both global climate change and anthropogenic activities.To understand the scope of these changes and the mechanisms behind them is of paramount importance for the sustainable development of China,and for the establishment of national policies on environment protection and climate change mitigation.Here we provide a brief review of the impacts of global climate change and human activities on the oceans in general,and on the ecosystems of China seas and coasts in particular.More importantly,we discuss the challenges we are facing and propose several research foci for China seas/coasts ecosystem studies,including long-term time series observations on multiple scales,facilities for simulation study,blue carbon,coastal ecological security,prediction of ecosystem evolution and ecosystem-based management.We also establish a link to the Future Earth program from the perspectives of two newly formed national alliances,the China Future Ocean Alliance and the Pan-China Ocean Carbon Alliance.

Background Long-term use of antiplatelet agents, statins, beta-blockers and angiotensin-converting enzyme inhibitors are proven therapies for secondary prevention in acute coronary syndrome. However, little is known of physicians＇ opinion about their use in China. Methods In 2010, standard questionnaires were posted to chief cardiologists in 1397 geographically diverse and representative sample of tertiary and secondary hospitals in China, collecting information about their opinions on the recommended treatments for acute coronary syndrome. Results A total of 1009 （72%） cardiologists responded with a valid questionnaire. Of them, 77% reported routine use of all the four main secondary preventive treatments, with little difference between secondary and tertiary hospitals （75% vs. 79%, P=0.16）. Of the cardiologists reporting routine or selective use of aspirin, beta-blockers, statins and angiotensin-converting enzyme inhibitors, 94%, 85%, 73% and 86% would recommend indefinite use respectively. For all the 4 treatments combined, only 63.5% reported indefinite use at the same time, with no significant difference between secondary and tertiary hospitals （62% vs. 65%, P=0.17）, nor between hospitals with or without fast track for primary percutaneous coronary intervention （66% vs. 61%, P=0.50）. Conclusions Although Chinese cardiologists seem we treatments for acute coronary syndrome, there is still gap in use of these treatments. informed about the value of main secondary preventive their understanding of the need for combined and prolonged

二通插装阀组合而成的功能阀在各类高压大流量系统中应用广泛。常用的O型机能三位四通换向功能阀由P型先导电磁阀+二通插装阀组合而成,有一种由O型先导电磁阀+二通插装阀组合而成的换向阀,不仅具有O型机能三位四通功能,同时在进油端还集成防反冲功能,在系统急停等情况下供油端已卸荷,因换向功能阀阀芯未来得及关闭到位,可有效防止液压缸压力油瞬间超大流量回流并经已卸荷的电磁溢流阀回油的情况。但这种换向功能阀在使用一段时间后出现回油压力异常增高的现象。本研究为了解异常现象的背后机理,首先通过介绍其详细工作原理,分析并定位了影响回油压力异常增高的几个可能因素,针对换向功能阀,基于AMESim软件仿真模拟不同先导阻尼孔径对插装阀压力损失的影响效果来复现故障,再通过现场试验,验证了分析结果,最后给出了设计细节方面的优化建议。

Left ventricular hypertrophy associated with the use of tacrolimus is a rare complication of solid organ transplantation in adult recipients. We present a cardiac transplant recipient who developed severe concentric left ventricular hypertrophy with congestive heart failure related to myocardial hypertrophy on tacrolimus. Hypertrophy improved when the drug was discontinued and replaced with sirolimus.
