硒对小鼠亚急性阿霉素心肌损害的保护作用

本文以1次剂量阿霉素(ADR 17.5mg/kg ip)引起小鼠亚急性心肌早期病变,探讨硒的保护作用。预先给硒(Se 80μg/kg×10 ip)可防止ADR所致心肌早期损害(D—PAS染色物质显示的细胞膜通透性增加)。这种保护可能与心肌硒水平和谷胱甘肽过氧化物酶活性增高从而降低脂质过氧化产物水平有部分关系。     

电视腹腔镜胆囊切除术

<正> 胆囊结石是外科最常见疾病之一。传统的胆囊切除术百余年来一直被认为是治疗这一疾病最有效的方法.1987年法国医生Mouret在腔内镜技术发展的基础上率先在腹腔镜下行胆囊切除术(LC)获得成功。     

Preparation and Characterization of the Covalent-Integrated Poly（lactic acid） and Scrap Leather Fiber Composites

Scrap leather fibers (SLFs) modified with active silane containing epoxide groups were incorporated into poly(lactic acid) (PLA) modified by vinyl trimethoxysilane, i.e., the PLA/SLF composites were prepared for bio-composites by solvent compounding technology in this article. The effects of silane coupling agents on the structures of PLA and SLF molecules were examined, and the mechanical properties and thermal stability of PLA/SLF composites were also measured. The results of Fourier-transform infrared spectroscopy (FTIR) had proved that silane had been incorporated successfully to PLA and SLF molecules by means of the solvent technology. Scanning electric microscopy (SEM) was used to investigate both the changes in shapes between the pristine SLFs and the treated SLFs and the microscopic structures of composites. According to SEM results, it was shown that there were some significant differences between the untreated and treated SLFs, and a double continuous phase structure had occurred in PLA/SLF composites due to the excellent dispersion of SLFs in matrix. The addition of the treated SLFs into PLA resulted in a distinct improvement of the impact and tensile strengths. When the mass fraction of the treated SLFs was 15%, the notched impact strength and tensile strength of PLA/SLF bio-composites were improved by 34.4% and 21.2% compared with the pristine PLA, respectively. Additionally, with the increase of the modified SLFs content, the thermal stability of PLA/SLF bi-composites was apparently improved. The macroscopic properties of bio-composites were found to be strongly dependent on their components, concentration, dispersion and resulted morphological structures.

从60年历史纵观胆囊癌诊治进展

西安交通大学第一附属医院在胆囊癌诊治方面已有60余年的历史,1956—2018年共收治3430例胆囊癌患者,其中手术治疗1941例,根治性手术703例.通过对比分析1956—2008年和2009—2018年的数据,胆囊癌根治性切除率由19.9％提升至48.3％.在预后方面,2004—2008年胆囊癌区域性根治术及扩大根...     

影像学检查对恶性梗阻性黄疸的诊断价值

我院1985～1993年间收治的恶性梗阻性黄疸171例,所有病例均经B型超声（B-us）、内窥镜下逆行胰胆管造影（ERCP）、经皮肝穿刺胆管造形（PTC）及电子计算机断层扫描（CT）等影像学检查,并经手术证实。通过分析比较,详细地讨论了各种影像学检查的优缺点及特点。指出:入院前即完成肝功、B-us检查。对肝内胆管扩张者,采用PTC检查,对不扩张者采用ERCP检查,若ERCP失败,也可改用PTC方法,对于低张十二指肠造影不做为常规的检查方法。     

胆石中游离和结合胆汁酸定量分析研究(薄层扫描色谱法)

在付立叶变换红外光谱(FT-IR)定性分类胆石的基础上,用薄层扫描色谱法进行胆石中游离和结合胆汁酸的定量分析研究。60例胆石经FT-IR 分为7种类型:胆固醇结石,胆固醇混合石、胆色素混合石、色素新型石、类色素型石、黑石磷酸盐型和黑石蛋白型。本文将从不同类型胆石游离和结合胆汁酸含量的差异,探讨胆汁酸在胆石成因中的作用.
