Objective Most patients with sepsis were diagnosed in the emergency department when admitted to the hospital. This study aimed to explore independent factors for hospital mortality in sepsis patients in the emergency *** It was a retrospective study. All patients with sepsis admitted to the emergency department of Changsha Central Hospital between 1 July 2020 and 1 July 2021 were included. Variables that showed significant differences between the survivor group and the non-survivor group were caculated in multivariate logistic regression analysis. Independent factors associated with in-hospital mortality in sepsis were *** A total of 194 patients were included in this study. In-hospital mortality was 17.01%(n=33). Two independent risk factors including albumin(ALB) and urea nitrogen were identified by multivariate logistic regression analysis. The optimal cut-off values of ALB and urea nitrogen were 26.5g/L and 8.03mmol/L. While combined ALB and urea nitrogen, the area under the ROC curve(AUC) was 0.790, which was superior to the SOFA, qSOFA, and APACHEⅡ*** Independent factors including ALB and urea nitrogen for in-hospital mortality in sepsis in the emergency department were identified. It could help physicians identify those patients with a higher risk of a poor prognosis early and easily, so intervention and management could be performed quickly.

伴随金融实践日新月异的变化,新金融中介理论在提高其解释力的过程中不断拓展其分析视野,内容得到了极大的丰富,理论的发展不断走向完善和深入。追寻新金融中介理论的发展轨迹,我们看到:一是金融中介的研究边界逐步发生着变化,由传统的存款类机构转向更广义的中介机构(包括共同基金和养老基金等);二是在寻求金融中介的存在根由上,从外生性因素分析转向内生性因素分析;三是金融中介与市场的关系开始从静态对立的竞争关系转向动态互补的共生关系;四是对金融中介的总体研究范式一改以往狭隘的机构观,而代之以更具有说服力的功能观。

戈德史密斯(1969)和爱德华.肖(1973)分别对发达国家和落后国家的金融发展状况进行了实证研究,得出了落后国家经济之所以落后,主要是因为其金融发展与发达国家之间存在着明显的差异的结论,由此提出了金融深化的观点,标志着金融发展理论的形成。在金融发展理论的指导下,许多落后国家纷纷改革其金融体制,推行金融自由化,以促进其金融发展。然而20世纪90年代以后,全球金融危机的频繁爆发,引起了人们对金融发展理论的反思。金融发展理论的再度兴起,使金融发展的涵义不断得到丰富与发展,金融发展涵义从结构观、制度观向功能观和环境观逐步演进。

目的探讨两种全身麻醉方式对腹腔镜下根治性广泛全子宫切除术患者术后认知功能的影响。方法将100例择期腹腔镜下根治性广泛全子宫切除术患者分为两组:丙泊酚组(P组)、七氟醚组(S组),每组各50例。记录麻醉时间、舒芬太尼用量、维库溴铵用量、苏醒时间、定向力恢复时间,记录麻醉复苏期并发症。分别于术前1d(T_0)、术后1d(T_1)、术后3d(T_2)、术后7d(T_3)、术后1个月(T_4)、术后3个月(T_5)对患者进行简易智能状态量表(MMSE)评分,采用Z计分法评定术后认知功能障碍(POCD)发生情况。结果与P组比较,S组舒芬太尼用量及维库溴铵用量较少(P<0.05),苏醒时间及定向力恢复时间增加(P<0.05),S组患者出现寒战、躁动、上呼吸道梗阻较多(P<0.05)。组间MMSE评分变化相比较,差异无统计学意义(F=0.14,P=0.709);时间点MMSE评分变化相比较,差异有统计学意义(F=74.46,P<0.01);全身麻醉方式与时间MMSE评分之间存在交互效应(F=7.99,P<0.01);与P组比较,T_1、T_2时间点S组MMSE评分较低(P<0.05),S组中T_1、T_2、T_3、T_4时间点POCD发生率高(P<0.05)。结论腹腔镜下根治性广泛全子宫切除术中,采用七氟醚吸入麻醉患者较丙泊酚麻醉患者POCD发生率较高,但3个月后POCD发生率无差异。

利用山西省忻州市日光温室的室内小气候观测数据及气象站资料,用BP神经网络及逐步回归法建立多种输入变量不同天气条件下的日光温室内最高温度、最低温度的模型。结果表明:利用BP神经网络及逐步回归法建立的模型R2均在0.96以上,RMSE与AE大部分在2℃之下,模拟精度较高。利用逐步回归方法在模拟日光温室内晴天最高、最低温度和寡照的最高温度精度较高,利用BP神经网络模型在多云天气的最高、最低温度与寡照的最低温度模拟的精度较高。选择精度更好的模型对日光温室的极端气温做准确的预测,可为山西省设施农业的管理和调控及小气候预报提供支持。
