Objective: To analyze National Chinese Medicine Master Liu Shangyi’s prescription characteristics of clinical medicinefor the treatment of cancer patients with stomachache. Methods: Data on prescriptions for cancer patients withstomachache between January 2014 and July 2016 were collected. The composing principles were analyzed byunsupervised data mining methods including Apriori algorithm in association rules and complex system entropy cluster.Results: Based on the analysis of 120 prescriptions, the frequency of each herb and association rules among the herbswere computed. Four core combinations and two new prescriptions were mined from the database. Compared to thebefore treatment, the clinical symptomatic grading of stomachache after treatment was lower (P 〈 0.001). Conclusion:Professor Liu has been successful in the treatment of cancer patients with stomachache by prescribing medication thataids in activating blood circulation, removing dampness, and alleviating pain. 展开更多

On January 10, 1998, an earthquake of ML=6.2 occurred in the border region between the Zhangbei County and Shangyi County of Hebei Province. This earthquake has been the most significant event occurred in the northern China in the recent years. Historical seismicity in the Zhangbei-Shangyi region was very low. In the epicentral area no active fault capable of generating a moderate earthquake like this event was found. The earthquake locations of the main shock and its aftershocks of the Zhangbei-Shangyi earthquake sequence given by several agencies and authors were diverse and the resulted hypocentral distribution revealed no any dominant horizontal lineation. To study the seismogenic structure of the Zhangbei-Shangyi earthquake, in this paper the main shock and its aftershocks with ML3.0 of the Zhangbei-Shangyi earthquake sequence were relocated using the master event relative relocation algorithm. The relocated results show that the epicentral location of the main shock was 41.145癗, 114.462癊, which was located 4 km to the NE of the macro-epicenter of the main shock. The relocated focal depth of the main shock was 15 km. The hypocenters of the aftershocks distributed in a nearly vertical N20E-striking plane and its vicinity. The relocated results of the Zhangbei-Shangyi earthquake sequence clearly indicated that the seismogenic structure of this event was a nearly N-S- to NNE-SSW-striking fault with right-lateral and reverse slip, and that the occurrence of this event was associated with the horizontal and ENE-oriented compressive tectonic stress, which was compatible with the tectonic stress field in the northern China. 展开更多

On January 10, 1998, at 11h50min Beijing Time (03h50min UTC), an earthquake of ML=6.2 occurred in the border region between the Zhangbei County and Shangyi County of Hebei Province. This earthquake is the most significant event to have occurred in northern China in the recent years. The earthquake-generating structure of this event was not clear due to no active fault capable of generating a moderate earthquake was found in the epicentral area, nor surface ruptures with any predominate orientation were observed, no distinct orientation of its aftershock distribution given by routine earthquake location was shown. To study the seismogenic structure of the Zhangbei- Shangyi earthquake, the main shock and its aftershocks with ML3.0 of the Zhangbei-Shangyi earthquake sequence were relocated by the authors of this paper in 2002 using the master event relative relocation technique. The relocated epicenter of the main shock was located at 41.145癗, 114.462癊, which was located 4 km to the NE of the macro-epicenter of this event. The relocated focal depth of the main shock was 15 km. Hypocenters of the aftershocks distributed in a nearly vertical plane striking 180~200 and its vicinity. The relocated results of the Zhangbei-Shangyi earthquake sequence clearly indicated that the seismogenic structure of this event was a NNE-SSW-striking fault with right-lateral and reverse slip. In this paper, a relocation of the Zhangbei-Shangyi earthquake sequence has been done using the double difference earthquake location algorithm (DD algorithm), and consistent results with that obtained by the master event technique were obtained. The relocated hypocenters of the main shock are located at 41.131癗, 114.456癊, which was located 2.5 km to the NE of the macro-epicenter of the main shock. The relocated focal depth of the main shock was 12.8 km. Hypocenters of the aftershocks also distributed in a nearly vertical N10E-striking plane and its vicinity. The relocated results using DD algorithm clearly indicated that the seismogenic structure of this event was a NNE-striking fault again. 展开更多

The regional seismotectonic environment for the Zhangbei- Shangyi earthquake is described, and in combination with the distribution of macroscopic seismic intensity, source mechanism solution, and interpretation of lineaments on satellite images, the seismogenic structure for the earthquake and possible seismogenic fault are discussed in this paper. It is suggested that the Zhangbei-Shangyi earthquake is a result of the latest movement along the northwestern termination of the Zhangjiakou-Penglai fault zone and we should pay serious attention to the future trend of seismic activity along this fault zone. 展开更多

The study of deep-seated structure in the Zhangbei-Shangyi earthquake area and its surroundings indicates that in comparison with the Shanxi rift system, the North China rifted basin, the Yanshanian fold belt on both sides, and the Zhangjiakou-Penglai tectonic belt have lower resistivity, and a distinctly different velocity interface in the crust and depth distribution of Moho discontinuity. The Yanqing- Huai’lai basin bisects the Zhangjiakou-Penglai tectonic belt into two segments, the northwestern and the southeastern segments. The latest magnetotelluric sounding and investigation indicate that the electrical structure within the Zhangbei-Shangyi earthquake area is different to a certain degree from that in its surroundings. There exists a nearly NNW-trending structure in the crust. The main shock and most aftershocks occurred above the low-resistivity zone in the crust. 展开更多

High-value subsurface fluid anomalies appeared in the northern part of North China region for more than two years before the Zhangbei-Shangyi earthquake. Some of the anomalies have appeared alternately and were correlated with moderate and moderately strong earthquakes in the region during the last year (1997). Typical short-term subsurface fluid anomalies have appeared in the area at 100 km ~ 200 km distance from the epicenter for two months before an earthquake. Tracing these anomalies during the last two years and repeatedly improving the knowledge of seismic regime, we have more successfully performed short-term and imminent earthquake prediction at half a month before its occurrence. 展开更多

On 10 January, 1998 an earthquake of Ms=6.2 occurred in the Zhangbei-Shangyi region of North China. The surface seismic deformation was measured in the previous study using the 3 pass ERS-1/2 SAR differential inter-ferometric technology (D-INSAR). In this note the focal mechanism of Zhangbei-Shangyi earthquake is estimated from the D-INSAR measurement of surface deformation based on a standard elastic dislocation model for seismic displacement. The inversion procedure is an iterative, linear least-squares algorithm. Through the relation between the focal parameters and displacement in the line of sight direc-tion measured in the radar interferogram, the optimum focal parameter set is derived. The results show that the seismic fault of Zhangbei-Shangyi earthquake is a thrust fault dip-ping SW with a large right-lateral displacement component. The strike and dip are 95°and 30°respectively on a fault patch of 12 km long by 14 km wide. Its hypocenter is located at N40°58’, E114°21’, and 7.5 km in depth. 展开更多
