日本居家安宁疗护服务体系构建经验及其对我国的启示

21世纪的日本"少子高龄化"特征明显，发展居家安宁疗护、构建完备的居家安宁疗护服务体系，是日本卫生服务提供体制改革的重要方向。本文介绍了日本居家安宁疗护的含义与理念，以及关于居家安宁疗护服务提供机构、提供人员、提供内容及费用保障的法律规定，提示我国在条件成熟时应尽快健全安宁疗护相关立法，在卫生服务提供体系框架下实现居家安宁疗护的稳定发展，建立并强化安宁疗护过程中的协作机制，并为居家安宁疗护提供必要的经费保障，通过完善的制度设计保障老年人"居家善终"的权益。     

Proteomics analysis of lysine crotonylation and 2-hydroxyisobutyrylation reveals significant features of systemic lupus erythematosus

Introduction/objectives

To seek significant features of systemic lupus erythematosus (SLE) by utilizing bioinformatics analysis.

Method

Liquid chromatography-tandem mass spectrometry (LC–MS/MS) was used to quantify lysine crotonylation (Kcr) and lysine 2-hydroxyisobutyrylation (Khib) in peripheral blood mononuclear cells (PBMCs) of systemic lupus erythematosus (SLE) patients and normal controls.

Results

Seventy-six differentially modified proteins (DMPs) dually modified by Kcr and Khib were identified between SLE patients and healthy people. GO enrichment analysis prompted significant enrichment of seventy-six DMPs in MHC class II protein complex binding and leukocyte migration. KEGG pathways were enriched in antigen processing and presentation pathway and leukocyte transendothelial migration pathway. Six DMPs (CLTC, HSPA1B, HSPA8, HSP90AB1, HSPD1, and PDIA3) were identified in antigen processing and presentation pathway, of which HSPA8 was the core protein. Significant changes of Kcr and Khib in HSPA8 may increase ATP hydrolysis and promote antigen binding to MHC II molecule. In leukocyte transendothelial migration pathway, 7 DMPs (ACTN1, ACTN4, EZR, MSN, RAC1, RHOA, and VCL) were identified. MSN was the protein with the most modification sites in this pathway. In amino terminal ferm region of MSN, Kcr and Khib expression change may lead to the adhesion between leukocytes and endothelial cells, which was an important step of leukocyte migration.

Conclusion

Kcr and Khib may promote the antigen presentation and jointly regulate the tissue damage mediated by leukocyte migration in SLE patients, which may play key roles in the pathogenesis of SLE probably.

青年人群近距离工作后眼部参数的变化及恢复时间

目的：观察青年人群近距离用眼后眼部生理及功能性参数的变化及恢复时间。

方法：前瞻性研究。随机选取2019-12/2020-06在我院进行医学验光的患者69例138眼，根据主觉验光结果分为正视组(+0.75D≤等效球镜度≤-0.50D，18例36眼)、低度近视组(-0.75D≤等效球镜度≤-3.00D，25例50眼)和中度近视组(-3.25D≤等效球镜度≤-6.00D，26例52眼)。所有受试者近距离阅读20min后远眺放松20min，分别于近距离用眼前、近距离用眼20min后、远眺5、10、15、20min时测量受试者眼部生理性参数\〖前房深度(ACD)、眼轴长度(AL)\〗和功能性参数\〖正相对调节(PRA)、调节反应(BCC)\〗，分析各参数的达极时间和恢复时间。

结果：近距离用眼后眼轴变长，前房变浅，PRA绝对值变大，BCC无明显变化，75%(52/69)的受试者AL在近距离用眼20min后达极，87%(60/69)的受试者ACD在远眺5min时达极，96%(66/69)的受试者PRA在近距离用眼20min后达极，且以上参数均在远眺10min后逐渐恢复至初始状态。

结论：近距离用眼后眼部参数发生改变，眼轴变长，前房变浅，PRA绝对值增大，但均在远眺放松过程中逐渐回退，且均需要10min以上才能恢复至初始状态。     

首批依诺肝素钠国家对照品1,6-脱水衍生物含量赋值的协作研究

目的： 建立首批1,6-脱水衍生物系统适用性对照品，完善国家标准。方法：以欧洲药典依诺肝素钠对照品(EP Enoxaparin Sodium，Batch5)为系统适用性对照品，采用依诺肝素钠新国家标准草案 “1,6-脱水衍生物”检查法，对依诺肝素钠国家对照品(批号：140810-201801)进行1,6-脱水衍生物含量测定，由全国14个药品检验机构及依诺肝素生产企业实验室协作标定。结果：对依诺肝素钠系统适用性国家对照品(批号：140810-201801)1,6-脱水衍生物含量标定结果为20.3%，并对实验室内误差进行考察，14个实验室中有1个实验室(Lab1)标准差(SD)为1.8%，5个实验室(Lab2、Lab4、Lab10、 Lab11和Lab13)的SD为0.5%~0.7%，其余8个实验室的SD值均小于0.5%。对实验室间误差进行考察，有效数据的SD值为0.6%，相对标准偏差(RSD)为3.2%。结论：经国家药品标准物质委员会审定后批准， 依诺肝素系统适用性国家对照品(批号：140810-201801)增加1,6-脱水衍生物含量赋值，可以用于依诺肝素钠1,6-脱水衍生物检查系统适用性考察使用。
