The thermal history of sedimentary basins is a key factor for hydrocarbon accumulation and resource assessment, and is critical in the exploration of lithospheric tectono-thermal evolution. In this paper, the Cenozoic thermal histories of nearly 200 wells and the Mesozoic thermal histories of 15 wells are modeled based on the vitrinite reflectance and apatite fission track data in Bohai Bay Basin, North China. The results show that the basin experienced Early Cretaceous and Paleogene heat flow peaks, which reveals two strong rift tectonic movements that occurred in the Cretaceous and the Paleogene in the basin, respectively. The thermal evolution history in Bohai Bay Basin can be divided into five stages including（1） the low and stable heat flow stage from the Triassic to the Jurassic, with the heat flow of 53 to 58 m W/m2;（2） the first heat flow peak from the Early Cretaceous to the middle of the Late Cretaceous, with a maximum heat flow of 81 to 87 m W/m2;（3） the first post-rift thermal subsidence stage from the middle of the Late Cretaceous to the Paleocene, with the heat flow of 65 to 74 m W/m2 at the end of the Cretaceous;（4） the second heat flow peak from the Eocene to the Oligocene, with a maximum heat flow of 81 to 88 m W/m2; and（5） the second thermal subsidence stage from the Neogene to present, with an average heat flow of 64 m W/m2.

Owing to the lack o f terrestrial heat flow data, studying lithospheric thermal structure and geodynamics of the Yingen-Ejinaqi Basin in Inner Mongolia is limited. In this paper, the terrestrial heat flow o f the Chagan sag in the YingenEjinaqi Basin were calculated by 193 system steady-state temperature measurements of 4 wells, and newly measuring 62 rock thermal conductivity and 20 heat production rate data on basis o f the original 107 rock thermal conductivity and 70 heat production data. The results show that the average thermal conductivity and heat production rate are 2.11 ±0.28 W/(m.K) and2.42±0.25 nW/m^3 in the Lower Cretaceous o f the Chagan sag. The average geothermal gradient from the Lower Suhongtu 2 Formation to the Suhongtu 1 Fonnation is 37.6 °C/km, and that o f the Bayingebi 2 Formation is 27.4 °C/km. Meanwhile, the average terrestrial heat flow in the Chagan sag is 70.6 mW/m^2. On the above results, it is clear that there is an obvious negative correlation between the thermal conductivity o f the stratum and its geothermal gradient. Moreover, it reveals that there is a geothermal state between tectonically stable and active areas. This work may provide geothermal parameters for further research o f lithospheric thermal structure and geodynamics in the Chagan sag.

目的探讨血清补体C1q/肿瘤坏死因子相关蛋白3(CTRP3)、波形蛋白(VTN)水平与扩张型心肌病慢性心力衰竭患者预后的关系。方法选取2021年1月至2022年8月河北省邢台市中心医院收治的扩张型心肌病慢性心力衰竭患者179例,根据1年预后分为预后不良组(63例)和预后良好组(116例)。采用酶联免疫吸附试验检测血清CTRP3、VTN水平。单因素和多因素logistic回归分析影响扩张型心肌病慢性心力衰竭患者预后的因素,受试者操作特征曲线分析血清CTRP3、VTN水平对扩张型心肌病慢性心力衰竭患者预后不良的预测价值。结果随访1年,179例扩张型心肌病慢性心力衰竭患者预后不良发生率为35.20%(63/179)。两组年龄、慢性心力衰竭病程、心功能分级、左室射血分数(LVEF)、CTRP3、VTN比较,差异有统计学意义(P0.05)。年龄增加[OR(95%CI):1.090(1.007~1.179)]、心功能分级增加[OR(95%CI):3.868(1.405~10.652)]、VTN升高[OR(95%CI):1.101(1.039~1.167)],LVEF增加[OR(95%CI):0.680(0.543~0.850)]和CTRP3升高[OR(95%CI):0.946(0.916~0.978)]为扩张型心肌病慢性心力衰竭患者预后不良的影响因素(P<0.05)。血清CTRP3联合VTN水平预测扩张型心肌病慢性心力衰竭患者预后不良的曲线下面积(0.878)大于血清CTRP3、VTN水平单独预测的0.782、0.787(Z=3.779、3.546,P<0.05)。结论扩张型心肌病慢性心力衰竭患者血清CTRP3水平降低、VTN水平升高与预后不良密切相关,二者联合预测扩张型心肌病慢性心力衰竭患者预后不良的价值较高。
