邓小平关于中国农业实行家庭联产承包责任制和发展适度规模经营的“两个飞跃”的构想 ,开辟了中国社会主义农业发展之路。中国农业成功地进行了“第一个飞跃”,实现了历史性的超越。在取得巨大成功的同时 ,“第一个飞跃”也产生了一些制约中国农业进一步发展的新问题。“第二个飞跃”的酝酿现已悄然起步。在实现“第二个飞跃”的进程中 ,家庭联产承包责任制的基本原则不能改变 ,但同时又要解决好诸如农地流转、农业产业化经营等深层次问题。

aiM： To investigate whether the recombinant adenovirus induces the TNF-α-mediated apoptosis in vivo. METHODS： Human hepatocarcinoma cell line （HepG2） cells were transfected into BALB/c nude mice, and the tumor growth curve was drawn. We analyzed apoptosis in HepG2 cells by TUNEL, HE staining and electron microscopy. RESULTS： AdIκBαM was expressed stably and efficiently in HepG2 and could not be degraded by induction of TNF-α. Tumor growth in mice could be reduced remarkably if treated by AdIκBαM plus TNF-α. There was apoptosis of 〉 70% of cells treated with AdIκBαM plus TNF-α and about 50% of cells treated with AdIκBαM. In contrast, there was few cell apoptosis in HepG2 cells treated with phosphate buffered saline and AdIκBαM. HepG2 cells in mice also exhibited a high level of apoptosis after in vivo injection with AdIκBαM. The tumor growth curve indicated the tumor transfected with AdIκBαM could be restrained. CONCLUSION： AdIκBαM gene therapy greatly enhances apoptosis due to inhibition of an NF-κB-mediated antiapoptosis signaling pathway.

目的观察参苓白术散加减联合光动力疗法(PDT)治疗复发性阿弗他溃疡(RAU)的临床观察。方法将70例R AU病例随机分为2组,中药组35例,给予参苓白术散加减治疗;PDT组35例,在中药组治疗基础之上,局部涂搽光敏剂后予以红光照射处理。分别观察中药组和PDT组局部证候的改善情况,观察周期为6天。结果治疗前后比较,两组溃疡面积大小、溃疡疼痛指数(VAS评分)、愈合时间均有不同程度的改善(P<0.05);且PDT组较中药组在减轻溃疡疼痛、缩小溃疡面积大小、增加愈合时间都更有明显优势(P<0.05)。结论参苓白术散加减联合光动力疗法(PDT)治疗复发性阿弗他溃疡(RAU)的临床疗效优于参苓白术散加减,临床值得推广应用。

Since the room-temperature detector CdZnTe(CZT) has advantages in terms of detection efficiency,energy resolution, and size, it has been extensively used to detect X-rays and gamma-rays. So far, nuclear radiation detectors such as cerium chloride doped with lanthanum bromide(LaBr_3(Ce)), thallium doped with cesium iodide(sI(Tl)), thallium doped with sodium iodide(Nai(Tl)),and high-purity germanium(HPGe) primarily use the spectroscopy-dose rate function(G(E)) to achieve the accurate measurement of air kerma rate(K_a) and ambient dose equivalent rate(H*(10)). However, the spectroscopy-dose rate function has been rarely measured for a CZT detector. In this study, we performed spectrum measurement using a hemispherical CZT detector in a radiation protection standards laboratory. The spectroscopy-dose rate function G(E) of the CZT detector was calculated using the least-squares method combined with the standard dose rate at the measurement position. The results showed that the hemispherical CZT detector could complete the measurement of air kerma rate(K_a) and ambient dose equivalent rate(H*(10)) by using the G(E) function at energies between 48 keV and 1.25 MeV, and the relative intrinsic errors were, respectively, controlled within ± 2. 3 and ± 2. 1%.
