In this research, based on continuous nearly 50-year data including runoff volume, sediment discharge as well as sediment accretion from hydrographic stations, and 10-year information of water quality from pollution monitoring stations, the method for measuring in-stream flow requirement has been put forward supported by experiential models and GIS spatial analysis. Additionally, the changes of in-stream flow requirement for environment and economic development have been addressed from spatial-temporal dimensions. The results show that： （1） According to the central streams in Yan＇an region, mean annual in-stream flow requirement reaches 1.0619 billion m^3, and the surface water for economic exploitation is 0.2445 billion m3 （2） Mean annual in-stream flow requirement for sediment transfers in flood period occupies over 80% of the integrated volume in a year. （3） From the 1950s to 1970s, in-stream flow requirement for sediment transfers is comparatively higher, while from the 1980s to 1990s, this requirement presents a decreasing tendency.展开更多

Standardized and unified logging interpretation results play a decisive role in fine reservoir description and reservoir development. Aiming at the problem of the conflict between the development effect and the initial interpretation result of Yan 9 reservoir in Hujianshan area of Ordos Basin, by combining the current well production performance, logging, oil test, production test and other data, on the basis of making full use of core, coring, logging, thin section analysis and high pressure mercury injection data, the four characteristics of reservoir are analyzed, a more scientific and reasonable calculation model of reservoir logging parameters is established, and the reserves are recalculated after the second interpretation standard of logging is determined. The research improves the accuracy of logging interpretation and provides an effective basis for subsequent production development and potential horizons.展开更多

METHODS Thirty four cases of cirrhosis (in decompensation) were divided into YGJY decotion treated group and control group treated by routine method. FN, FNR and TNF α were measured with ELESA and expressed as mg/L (FN, FNR) and ng/L (TNF α), and IL 1 was measured by mice thymocyte proliferation using β scintillation counter and expressed as cpm. RESULTS In YGJY decoction treated group, before treatment, FN was 247 9±97 2, FNR 5 6±2 7, TNF α 83 9±7 1 and IL 1 was 2760 8±813 6, and after treatment. FN was 298 3±93 2 ( P <0 01), FNR 4 3±2 3 ( P <0 05, TNF α 93 6±12 0 ( P <0 05) and IL 1 was 1922 3±847 0 ( P <0 05). The FN and TNF α plasma level after treatment increased remarkably, while FNR and IL 1 decreased obviously. In the control group before treatment, FN was 248 8±101 9, FNR 5 5±1 9, TNF α 126 1±48 1 and IL 1 was 2540 6±603 2, and after treatment was 241 6±77 1 ( P >0 05), FNR 5 4±1 2 ( P >0 05), TNF α 100 6±15 5 ( P >0 05) and IL 1 was 2360 6±860 0 ( P >0 05), the plasma levels of FN, TNF α, FNR and IL 1 did not change signifiantly. CONCLUSION YGJY decoction could prevent the process of the hepatic fibrosis by readjusting the plasma levels of FN, FNR, TNF α and IL 1 mediating acivities in cirrhosis, which is of clinical significance.展开更多

The results showed that the activity of the subtropical high had a significant impact on the occurrence of this rainstorm process. During the rainstorm in Yan'an,the subtropical high extended westward obviously,and the southerly airflow on the periphery of the subtropical high intersected with cold air in northern Shaanxi. The good coupling of high-and low-level jet stream provided dynamic conditions for the occurrence of downpour. During the rainstorm,the low-level jet stream at 850 h Pa was radial,and the high-level jet stream at 200 h Pa in this process was in a quasi-horizontal direction. In the rainstorm process,there was an obvious large-value band of water vapor transport,while the water vapor flux arrived at a high latitude,and the intensity was great.展开更多
