20世纪80年代初至1993年为我所计算机监控技术的研究探索阶段,完成了我国第一套水电厂计算机监控系统,并通过摸索几种不同结构模式的监控系统,取得了宝贵的试点经验。1994年起,国内水电厂兴起"无人值班"(少人值守)热潮,面向网络的H9000分布开放系统应运而生,为众多水电厂"无人值班"(少人值守)创造了条件。2000年进一步推出了高可靠性的H9000 V3.0系统,满足了大型水电厂无人值班的技术要求。随着三峡等以巨型机组特大型电站为特征的水电站的建设,我们又推出了高性能的H9000 V4.0系统,在三峡右岸投入运行后完全满足了运行的要求,登上了水电站计算机监控技术的制高点。文章主要从上述几个方面回顾了中国水科院自动化所成立30年来在水电厂计算机监控领域的发展和变化历程。

目的:探讨性激素及雌、孕激素受体(ER,PR)在男性青少年肥胖伴乳房发育症(OGMA)发病中的作用及三苯氧胺的疗效。方法:应用放射免疫分析法测定20例OGMA患者的血清性激素水平,免疫组化法检测其中10例乳腺组织ER、PR含量,并行三苯氧胺治疗。结果:OGMA患者血清总睾酮(TT)、睾酮/雌二醇(T/E2)降低,ER、PR阳性率均为80%。13例患者三苯氧胺治疗3个月,乳腺无明显缩小。结论:肥胖相关的血清TT、T/E2下降与OGMA发生密切相关,ER、PR含量增加是发病机制之一,三苯氧胺治疗本症疗效不确切。

In order to understand the mechanisms on the variation between rice cultivars in Cd uptake and accumulation, two pot soil experiments were conducted with typical rice cultivars that varied greatly in soil Cd uptake. The experiments with six rice cultivars showed that the root oxidation abilities of rice differed with rice cultivars and also with types of the cultivars, the cultivars with indica consanguinity were significantly higher than the cultivars with japonica consanguinity. Root oxidation abilities of the rice cultivars correlated positively and significantly （P〈0.01） with their Cd concentrations and Cd quantity accumulations in rice plants. The experiments with two rice cultivars showed that significant differences also existed between the two cultivars in pot soil redox potentials, which of Shan you 63 （higher soil Cd accumulator） were significantly higher than that of Wu yun jing 7 （lower soil Cd accumulator） under different soil Cd levels, but the degrees of the differences varied with soil Cd levels. The differences were larger under soil Cd treatments than the control. The results indicate that root oxidation ability, especially in Cd contaminated soil, is one of the main mechanisms which dominate Cd uptake and accumulation by rice plant.

The present study aimed to investigate the relationship between histopathological subtype and the probability of inguinal lymph node metastasis （ILNM） in patients with penile squamous cell carcinoma （PSCC）. The clinical records of 198 consecutive patients with PSCC were analyzed retrospectively. Primary lesions were reevaluated according to the 2016 World Health Organization （WHO） histopathological classification. We retrieved the clinicopathological factors from the medical records including age, clinical lymph node stage, pathological tumor stage, lymphatic invasion, and nerve invasion. Uni- and multivariate logistic regression analyses were used to explore the risk factors of ILNM. Multivariate analyses identified clinical lymph node stage （P = 0.000）, pathological tumor stage （P = 0.016）, histologic grade （P = 0.000）, and risk group of histological subtypes （P = 0.029） as independent predictors for ILNM. Compared with the low-risk group of PSCC subtypes, the intermediate- （HR： 3.66, 95% CI. 1.30-10.37, P = 0.021） and high-risk groups （HR： 28.74, 95% Ch 2.37-348.54, P = 0.008） were significantly associated with ILNM. In conclusion, the histopathological subtype of the primary lesion is a significant predictor for ILNM in patients with PSCC.
