平均血小板体积与动脉性勃起功能障碍的相关性研究

目的评估平均血小板体积(MPV)与动脉性勃起功能障碍(ED)之间的关系。方法选取动脉性ED患者153例,正常对照150例,比较两组年龄、体重、BMI、血小板数量、MPV、血小板分布宽度(PDW)、性腺六项、血脂、白细胞数、血红蛋白等指标,通过Logistic回归分析评价MPV与动脉性ED的相关性。结果两组年龄、体重、BMI、血小板数量,性腺六项、血脂、白细胞、血红蛋白及PDW等之间差异无统计学意义,MPV动脉性ED组明显高于对照组[(9.90±0.98)fl vs.(9.14±1.03)fl,P<0.01]。多因素Logistic回归分析结果显示:MPV与动脉性ED发生具有独立相关性(优势比:3.774,95%可信区间:1.435⁹.928;P<0.01)。结论 MPV作为评价血小板活性的指标,在动脉性ED患者中明显升高,是动脉性ED的独立危险因素。

Retrospective analysis of corticosteroid doses administered to patients with terminal cancer for dyspnea alleviation and survival

Dyspnea negatively affects the survival and quality of life of patients with terminal cancer. Although corticosteroids are currently used to treat dyspnea, the association between corticosteroid dosage and survival remains unclear. This retrospective study was conducted to determine the relationship betweencorticosteroid doses, administered to hospitalized patients with terminal cancer for dyspnea alleviation, and survival. Subsequently, we investigated the associations between corticosteroid doses, which were classified into three categories, and the length of survival in days after stratifying 52 patients treated between January 2012 and December 2015 into corticosteroid responders and non-responders. The mean daily corticosteroid doses were 28.68?±?14.4?mg for responders and 29.13?±?18.5?mg for non-responders. The mean corticosteroid doses on the first day were 27.86?±?14.9?mg for responders and 27.73?±?19.5?mg for non-responders. The mean total corticosteroid doses administered during the first 2 days of treatment were 56.84?±?29.2?mg for responders and 57.16?±?38.5?mg for non-responders. The mean survival was 11.33?±?7.5 days and 5.27?±?3.35 days among responders and non-responders, respectively. In conclusion, the administration of corticosteroid for dyspnea alleviation did not correlate with survival. However, reactivity to corticosteroids increased the duration of corticosteroid use, which may have contributed to survival.     

浅论国际医疗援助中的患者知情同意权

从国际医疗援助中患者知情同意权遭遇的尴尬入手,剖析了国际医疗援助中医患关系的独特性,即医患关系的复杂多变性、医患关系的临时应急性、患者自主选择权相对弱化、医生和患者的角色在一定条件下可转换。在此基础上,探究了国际医疗援助中落实患者知情同意权应把握的几个问题:人本理念至上;强化时效救治意识;采用人性化的沟通方式;落实患者知情同意权的评价原则。     

Relationship between Exposure to Pesticides and Occurrence of Acute Leukemia in Iran

Background: One of the causes of acute leukemia can be exposure to certain chemicals such as pesticides.This study determined the relationship between exposure to pesticides and the occurrence of acute leukemiain Fars province, south of Iran. Materials and Methods: Between April 2011 and April 2013 in a case-controlstudy conducted in Nemazee Hospital in Shiraz, Southern Iran; 314 subjects diagnosed with acute leukemia(94 pediatric cases and 220 adults) were enrolled to determine any correlation between exposure to pesticidesand the occurrence. Controls (n=314) were matched by sex and age. Results: There was a history of exposureto pesticides among 85% of pediatric cases and 69% of their controls and 83% of adult cases and 75% of theircontrols while 87.5% of pediatric cases and 90% of adult cases reported exposure to intermediate and high dosesof pesticides and among the controls, the exposure to low doses of pesticides was 70.5% and 65%, respectively.Exposure to indoor pesticides was seen among most of cases and controls. Being a farmer was at a significantlymore increased risk of developing acute leukemia in comparison to other jobs, especially for their children.Conclusions: Exposure to pesticides was shown to be one of the most important causes of acute leukemia. Itseems that there is a need to educate the people on public health importance of exposure to pesticides especiallyduring school time to reduce the risk of malignancies during childhood.     

维生素D3与结直肠癌相关性的研究进展

越来越多的研究证据已经表明,血清中低水平的维生素D₃（VD₃）与较高的结直肠癌（CRC）风险相关。目前大多数的观察性研究支持血清中25-(OH)-VD₃水平与CRC风险呈负相关性。然而,口服VD3或饮食中补充VD₃可否改善CRC患者的总生存期,目前还存在争议。本文将对近年来VD₃与CRC相关性的研究作一综述,以期有更多前瞻性的基础研究、临床研究和人群观察性研究对VD3是否对CRC的预防和治疗有价值做出澄清。
