  • Effects of Ulinastatin Therapy on Acute Lung Injury after Seawater Drowning in Rats

    Objective To investigate the protective effects of ulinastatin on acute lung injury ( ALI)induced by seawater drowning in rats. Methods Thirty male SD rats were randomly divided into three groups, ie. a control group, a model group, and an ulinastatin treatment group. The rats in the model group and the ulinastatin treatment group received intratracheal artificial seawater ( 4 mL/kg) instillation. Then the ulinastatin treatment group received ulinastatin ( 100 000 U/kg) injection after infusion of seawater while the model group received an injection of same amount of saline. The rats were sacrificed at 4 hours after instillation. The pathological changes of lung were evaluated by hematoxylin-eosin stain under light microscope. Lung wet/dry weight ratios were measured to assess the level of pulmonary edema.Concentrations of tumor necrosis factor ( TNF) -α, interleukin ( IL) -1β, IL-6, and IL-10 in bronchoalveolar lavage fluid ( BALF) were detected by enzyme-linked immunosorbent assay ( ELISA) . The myeloperoxidase activity in lung tissue homogenates were measured by colorimetric method. Results Ulinastatin treatmentsignificantly relieved the decline of PaO2 and lung pathological changes, inhibited myeloperoxidase activity,and reduced lung wet/dry weight ratios. Ulinastatin also inhibited the release of TNF-α, IL-1β, and IL-6,whereas increased the expression of IL-10 simultaneously. Conclusion Ulinastatin attenuates seawater induced ALI, which may be related to its inhibitory effects on inflammation reaction through regulating cytokine secretion.

  • Research on the cognitive frailty in maintenance hemodialysis patients

    The coexistence of cognitive impairment and physical frailty in maintenance hemodialysis (MHD) patients is known as cognitive frailty. It has emerged as a novel complication in MHD patients and increases the risk of adverse outcomes such as falls, fractures, functional impairment and death. Timely intervention can delay or even reverse the development of cognitive frailty to dementia, thereby reducing the risk of adverse outcomes and improving the quality of life of patients. Based on this literature review method, this article summarizes the domestic and foreign research progress on the epidemiology, assessment tools, influencing factors and intervention measures of cognitive frailty in MHD patients, aiming to provide reference for clinical staff to carry out early screening and intervention of cognitive frailty in MHD patients.

  • Correlation between Coronary Plaque Composition and Degree of Stenosis by 128-slice Spiral Computed Tomography Coronary Angiography in Patients with Coronary Heart Disease

    目的 应用128层螺旋CT冠状动脉成像,探讨冠状动脉不同成分斑块与狭窄程度的诊断价值。 方法 对2010年3月-2012年10月150例临床拟诊冠心病及确诊冠心病患者的128层螺旋CT冠状动脉成像检查,冠状动脉影像表现由两位心血管CT诊断医师独立判断冠状动脉斑块成分及测量冠状动脉狭窄程度。应用Circulation血管分析软件,分析冠状动脉斑块成分与狭窄程度之间的相关性。 结果 150例患者中,共发现319处斑块,其中软斑块104处,纤维、混合斑块103处,钙化斑块112处。冠状动脉轻度狭窄114处中,钙化斑块86处 (75.4%);冠状动脉中度狭窄113处中,纤维、混合斑块75处(66.3%);冠状动脉重度狭窄92处中,软斑块68处(73.9%)。 结论 128层螺旋CT冠状动脉成像能够有效检测患者冠状动脉斑块的成分及准确判断冠状动脉狭窄程度。

  • Preliminary exploration on the construction of “province, city, county, village” four-level hierarchical medical system in Yibin city

    The Second People’s Hospital of Yibin was taken over by West China Hospital of Sichuan University into its close hospital alliance, and simultaneously undertook the task of construction of regional hospital alliance in Yibin city. The article introduces the experiences of the Second People’s Hospital of Yibin in the high-quality development of novel healthcare system. Led by West China Hospital of Sichuan University and based on all-level medical institutions in Yibin, the Second People’s Hospital of Yibin preliminarily established a four-level hierarchical medical system as “province, city, county, village” model, according to the guide of governments within the whole region. It aims to propose a “Yibin model exploration” in hospital alliance construction based on the western regional situation.
