清热利湿法治疗酒精性肝炎疗效观察

目的：探讨清热显法治疗酒精性肝炎的临床疗效及机制。方法：45例酒精性肝炎患者随机分为两组，治疗组30例采用清热利湿法治疗，对照组15例采用常规西药治疗，观察两组临床疗效与外周血白细胞介素－8（IL－8），超氧化物歧化酶（SOD），丙二醛（MDA）水平及肝功能变化的关系。结果：经治疗后治疗组患者外周血IL－8，MDA水平均明显下降（P＜0．05，P＜0．01），SOD活性明显上升（P＜0．05），对照组患者外周血MDA水平均明显下降（P＜0．05），两组肝功能得到不同程度恢复，症状不同程度得到改善，两组总有效率比较差异无显著性意义（P＞0．05），但两组显效率比较差异有显著性意义（P＜0．05），结论：清热利湿法对酒精性肝炎具有较好疗效，其机制可能与下调炎症细胞因子IL－8水平，减轻肝脏脂质过氧化反应等有关。     

How narrative source impacts convergence of ratings from the Social Cognition and Object Relations Scale–Global Rating Method with psychotherapy process measures

This study examines the construct validity of the Social Cognition and Object Relations Scale–Global Rating Method (SCORS-G; Westen, 1995; see also Stein & Mulford, 2018) by exploring the degree of convergence across different narrative sources (i.e., early memories [EM] and psychotherapy narratives [PT]) in relation to patient- and therapist-rated psychotherapy process measures. Using a university-based outpatient sample (n = 81), we found limited convergence for SCORS-G ratings across narrative type. First, paired t tests showed that the means for six of the eight SCORS-G dimensions differed significantly between the EM and PT narratives with the majority having a large magnitude of effect. Moreover, despite 29 significant correlations between a SCORS-G dimension and either an alliance or session quality variable, only two of the eight SCORS-G dimensions significantly correlated with the same process variable across narrative type (e.g., patient-rated session depth with SCORS-G Self Esteem [SE] and Identity and Coherence of Self [ICS]). Importantly, the high degree of theoretical coherence in the associations that emerged between the SCORS-G dimensions and the process variables suggest that the lack of convergence was not due to limited validity of the SCORS-G. Instead, the results underscore the importance of multi-method assessment techniques by highlighting that the manner in which a narrative is elicited will impact the object relational content patients provide. Future research and clinical implications related to the SCORS-G, alliance and psychotherapy process are discussed.     

紧急床旁临时心脏起搏173例分析

对两种临时心脏起搏方法的效果和并发症作一分析。１７３例严重心律失常患者分别采用两种床旁临时起搏方法：即用球囊飘浮电极经静脉心内膜起搏１６９例，用钢丝电极剑突下经皮穿刺心内膜起搏４例。结果：用球囊飘浮电极经静脉心内膜起搏全部成功，起搏７（１～３１）天，电极脱位６例经重新安置电极后恢复起搏；穿刺损伤胸导管１例。用钢丝电极剑突下经皮穿刺心内膜起搏４例，１例成功；３例因心脏停搏时间太久而失败。结论：两种临时心脏起搏方法急救不宜搬动的严重心律失常病人均有效，但应视具体情况选用

Fracture risk of lithium-disilicate ceramic inlays: A finite element analysis

Objectives

In the present study, lithium-disilicate ceramic inlays should be analyzed biomechanically according to their thickness and dimension, and it should be clarified as to whether there is a significant relationship between the inlay volume and the induced tensile stress level.

Methods

Using a new parametric CAD modeling procedure, 27 lithium-disilicate ceramic inlays with various parameters of “depth”, “width”, “angle” and restoration volume were generated. These inlays were integrated into the CAD model of a lower molar created from the CT data of an anatomical preparation. The resulting CAD models were, finally, three-dimensionally cross-linked to FEM models. After applying a compressive force of 200 N, Principal Tensile Stresses (PTSs) could be measured in the inlay. The values were subject to statistical analysis afterwards.

Results

The volume of the inlay restorations varied between 35.7 mm³ and 82.5 mm³. The maximum PTS values (n = 10) only showed a slight negative correlation with the inlay volume. The correlation coefficient according to Spearman was −0.082 (p ≤ 0.001). If the highest 1000 PTS values of each inlay were considered (n = 1000), the correlation coefficient was further reduced to +0.068 (p ≤ 0.001). No significant correlation between the inlay volume and the induced PTS level could be detected.

Significance

Under the conditions and limitations of the present FEM study, the inlay volume did not significantly influence the tensile stress level of ceramic inlays. The results may support the thesis that volume-reduced all-ceramic inlays might not have an increased fracture risk. Further studies are needed to confirm this.
