高尿酸血症患者疾病不确定感与影响因素

目的探究高尿酸血症(HUA)患者疾病不确定感现状及影响因素。方法采用便利抽样方法,运用自行编制的一般资料量表、疾病不确定感成人量表、社会支持评定量表、医学应对方式量表,对496名HUA患者行问卷调查。结果疾病不确定感总分平均为(95. 79±9. 57)分,87. 36%患者处于中高水平;其中不明确性维度得分(37. 86±5. 18)分、复杂性维度得分(20. 56±1. 98)分、信息缺乏性维度得分(20. 96±2. 91)分、不可预测性维度得分(16. 41±1. 94)分。文化程度、客观支持、屈服、并发症、年龄、收入、饮酒是其疾病不确定感主要影响因素(P<0. 05)。医学应对方式中面对维度与不明确性、复杂性、信息缺乏性、不可预测性维度及疾病不确定感总分呈负相关(P<0. 05),屈服维度与疾病不确定感4个维度及总分呈正相关(P<0. 05)。结论 HUA患者疾病不确定感处于较高水平,与社会支持和医学应对方式存在相关性。医护人员应重视疾病不确定感影响因素,肯定和注重客观支持作用,采取积极的应对方式,以降低其疾病不确定感。全国高等医学教育学会(GJHLZ160018);;辽宁省教育厅(JG16DB139

Determination of D-ribose by ion chromatography with integrated pulsed amperometric detection

采用离子色谱-积分脉冲安培检测法(IC-IPAd)测定d-核糖,采用CArbO PACTM PA10色谱柱进行分离,60 MMOl/l nA OH溶液为淋洗液,流速0.6 M l/MIn,柱温30℃,Ed3000安培检测器,Au工作电极,TI对电极,Ag/Ag Cl复合参比电极。以外标法定量,d-核糖质量浓度为3.60~43.2Mg/l范围内峰面积呈良好的线性关系(r2=0.9999),检出限及定量限分别为0.200、0.620 ng,精密度实验的相对标准偏差(rSd)为0.524%,平均回收率为101%。因此,IC-IPAd可用于d-核糖含量的测定,且操作简便、无需衍生、分离效果好、灵敏度高。An analytical method was proposed and established for determination of D-ribose by ion chromatography with integrated pulsed amperometric detection(IC-IPAD).The separation was performed on a 250 mm×4 mm Carbo PacTM PA10 column at 30 ℃ by HPLC equipped with an ED3000 detector.The mobile phase was 60 mmol/L sodium hydroxide with a flow rate of 0.6 m L/min.The quantification was performed by an external standard approach.The concentration linear range for D-ribose was 3.60~43.2 mg/L(R2=0.9999).The relative standard deviation of precision was 0.524%.The detection and quantification limits for D-ribose were 0.200 ng and 0.620 ng,respectively.The average recovery ration for D-ribose was 101%.IC-IPAD was proved to be suitable for the determination of D-ribose with its convenience,rapidness,and sensitivity.海洋公益性专项(201105029); 国家重大科学仪器专项(2013YQ170525); 厦门市海洋经济发展专项资金项目(13CZP003HJ05

巢湖蓝藻水华的季节变化

&lt;正&gt;巢湖是中国第5大淡水湖,位于安徽省中部。100多年前已有记载:到了夏天,巢湖水面上漂浮有&quot;湖靛&quot;,即现在称作的蓝藻水华。历来,湖边农民捞这种湖靛作为肥料。这表明,巢湖蓝藻水华出现在环境污染严重化之前。上世纪90年代后,随着环境污染的日趋严

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
