Abstract: Previous studies have shown that the oxidizing brines from the Early Permian Rotliegende sequence have influences on the organic matter of Kupferschiefer. However, inside the Rotliegende sequence there are two other black shales: the Lower and Upper Antracosia shales, which have not been studied as much in detail as in Kupferschiefer. In the present study 12 samples from the Lower and Upper Antracosia shales were analyzed by organic geochemical methods in order to clarify the influences of the oxidizing brines on organic matter. The results indicate that the organic matter of the samples from the Upper Antracosia shale and the bottom of the Lower Antracosia shale was oxidized under the influences of the oxidizing brines. The oxidation resulted in a depletion of saturated hydrocarbons and the alkyls of the aromatic compounds.

目的:探讨股骨颈动力交叉钉系统(FNS)治疗中青年移位型股骨颈骨折过程中其动力棒偏移对术后早期临床结果的影响。方法:回顾性分析2019年12月至2023年1月期间苏州市立医院骨科采用FNS固定治疗的114例中青年移位型股骨颈骨折患者资料。根据术后FNS动力棒末端相对于股骨头颈中心轴线的偏移程度(W)不同分为两组:中心组(W≤20%)63例,男27例,女36例;年龄(46.4±8.0)岁。偏移组(W>20%)51例,男20例,女31例;年龄(45.1±9.8)岁。比较两组患者的术后患肢负重时间、骨折愈合时间、尖顶距、末次随访时股骨颈短缩程度、髋关节Harris评分、欧洲五维健康量表(EQ-5D-5L)效用值、并发症发生率及翻修手术率等。结果:两组患者术前一般资料及骨折复位质量比较差异均无统计学意义( P>0.05),具有可比性。两组患者术后患肢部分负重时间比较差异无统计学意义( P>0.05)。中心组患者术后患肢完全负重时间[15.0(14.0,16.0)周]、骨折愈合时间[14.0(12.0,15.0)周]显著短于偏移组患者[16.0(15.0,19.0)、15.0(13.0,17.0)周],尖顶距[(21.4±3.4)mm]显著小于偏移组患者[(23.5±2.7)mm],末次随访时髋关节Harris评分[(90.6±6.1)分]、EQ-5D-5L效用值[0.9(0.8,0.9)]显著高于偏移组患者[(87.7±6.2)分、0.9(0.8,0.9)],中重度股骨颈短缩发生率[25.4%(16/63)]、股骨头缺血性坏死发生率[0(0/63)]、翻修手术率[0(0/63)]显著低于偏移组患者[66.7%(34/51)、7.8%(4/51)、9.8%(5/51)],差异均有统计学意义( P< 0.05)。结论:FNS固定治疗中青年移位型股骨颈骨折时,将FNS动力棒尽可能靠近股骨头颈中心轴线置入可获得满意的临床疗效,并能降低翻修手术率。

目的分析腹膜透析相关性腹膜炎患者外周血基质金属蛋白酶抑制因子-1(TIMP-1)、基质金属蛋白酶抑制因子-2(TIMP-2)和转铁蛋白饱和度(TSAT)水平与临床转归的关系。方法选取2021年8月至2023年2月收治的100例腹膜透析相关性腹膜炎患者,根据患者拔除腹膜透析管后1年内临床转归情况将其分为治愈组(n=68)和恶化组(n=32)。比较2组临床资料及外周血TIMP-1、TIMP-2及TSAT水平,采用多因素Logistic回归分析影响腹膜透析相关性腹膜炎患者病情恶化的独立危险因素,采用受试者工作特征(ROC)曲线分析TIMP-1、TIMP-2及TSAT对患者临床转归的预测价值。结果恶化组透析龄高于治愈组,有腹膜炎病史患者占比大于治愈组,TIMP-1、TIMP-2和TSAT水平低于治愈组(P<0.01)。TIMP-1、TIMP-2和TSAT水平过低均是腹膜透析相关性腹膜炎患者病情恶化的独立危险因素(P<0.05)。ROC曲线分析显示,TIMP-1、TIMP-2和TSAT预测腹膜透析相关性腹膜炎患者临床转归的曲线下面积(AUC)分别为0.759、0.702和0.739,上述指标联合检测的AUC为0.813,具有更好的预测价值(P<0.05)。结论病情恶化的腹膜透析相关性腹膜炎患者TIMP-1、TIMP-2和TSAT水平降低,且三者及其联合检测对患者临床转归均有较高的预测价值。
