To the Editor:The papain-like protease(PL^(pro)),as one of the most important proteases of SARS-CoV-2,has emerged as a highly promising target protein,its inhibitor probably holds dual potentials,namely blocking the cleavage of viral polyprotein and intercepting the deubiquitination and deISGylation functions to restore antiviral immunity1.

Objective:Identifying novel strategies to prevent particulate matter(PM)-induced lung injury is crucial for the reduction of the morbidity of chronic respiratory *** combined intervention represented by herbal formulae for simultaneously targeting multiple pathological processes can provide a more beneficial effect than the single *** aim of this paper is therefore to design a safe and effective medicinal and edible Chinese herbs(MECHs)formula against PM-induced lung ***:PM-induced oxidative stress,inflammatory response and apoptosis A549 cell model were used to screen anti-oxidant,anti-inflammatory and anti-apoptotic MECHs,respectively.A network pharmacology method was utilized to rationally design a novel herbal *** performance liquid chromatography-mass spectrometer was utilized to assess the quality control of MECHs *** excretion of magnetic iron oxide nanospheres of the MECHs formula was estimated in *** MECH formula against PM-induced lung injury was investigated with mice ***:Five selected herbs were rationally designed to form a new MECH formula,including Citri Exocarpium Rubrum(Juhong),Lablab Semen Album(Baibiandou),Atractylodis Macrocephalae Rhizoma(Baizhu),Mori Folium(Sangye)and Polygonati Odorati Rhizoma(Yuzhu).The formula effectively promoted the magnetic iron oxide nanospheres excretion in *** mid/high dose formula significantly prevented PM-induced lung damage in mice by enhancing the activity of SOD and GSH-Px,reducing the MDA and ROS level and attenuating the upregulation of pro-inflammatory cytokine(IL-6,IL-8,IL-1βand TNFa),down regulating the protein expression of NF-κB,STAT3 and ***:Our findings suggest that the effective MECHs formula will become a novel strategy for preventing PM-induced lung injury and provide a paradigm for the development of functional foods using MECHs.

目的：分析进展期非小细胞肺癌患者采用短疗程、大分割胸部姑息放疗（palliative thoracic radiotherapy，PTR）的疗效及其不良反应。方法：回顾性分析天津医科大学肿瘤医院2010年9月至2012年7月行PTR的ⅢB期及Ⅳ期非小细胞肺癌患者共2... 详细信息

目的：分析进展期非小细胞肺癌患者采用短疗程、大分割胸部姑息放疗（palliative thoracic radiotherapy，PTR）的疗效及其不良反应。方法：回顾性分析天津医科大学肿瘤医院2010年9月至2012年7月行PTR的ⅢB期及Ⅳ期非小细胞肺癌患者共25例，其计划靶区（PTv）剂量为45Gy／15f，单次剂量3Gv。评价PTR症状缓解情况、放疗疗效及相关不良反应。Kaplan—Meier法进行生存分析并用Log-rank进行检验。结果：除l例患者只完成36Gy／12，其余24例均完成全部放疗计划。18例患者的胸部症状得到缓解，患者咳血症状缓解率为87．5％（7／8），咳嗽为70．6％（12／17），胸痛为73．3％（11／15），呼吸困难为57．1％（8／14），声音嘶哑为50％（1／2）。PTR后胸部病灶达部分缓解（PR）＋完全缓解（CR）为28％（17／25），未发现3级及以上放疗相关不良反应。患者的中位生存（overall survival，0s）为13个月（95％CI6．6～19．5个月），1年OS为51．5％（17／25）。单因素分析显示，PTR前KPS评分、PTR后化疗周期数是影响生存的重要因素。结论：对于进展期NSCLC患者，采用45Gy／15f短疗程、PTR剂量分割模式缩短了治疗时间．明显改善了患者的胸部症状，提高了OS，且近期不良反应较低，值得进一步进行大样本前瞻性随机分组研究。

【目的】建立树型金银花与野生金银花的HPLC指纹图谱,为全面、客观评价金银花质量、快速鉴别金银花品种提供依据。【方法】从陕西洛南、丹凤和河南灵宝等地收集树型金银花样品13份、野生金银花样品12份进行HPLC分析,将数据导入“中药色谱指纹图谱相似度评价系统(2012年版)”,以绿原酸色谱峰为参照峰,采用中位数法进行多点校正,建立树型金银花、野生金银花指纹图谱;应用SPSS 13.0软件,采用离差平方和法,以相对峰面积为评价指标,对2种金银花分别进行聚类分析;以绿原酸、异绿原酸、木犀草苷标准品为对照,用HPLC仪测定各样品中的3种成分含量。【结果】野生金银花指纹图谱匹配共有峰28个,树型金银花指纹图谱匹配共有峰13个。12份野生金银花样品中有10份与其对照指纹图谱相似度达0.95以上,13份树型金银花样品中有12份与其对照指纹图谱相似度达0.95以上,有24份样品与对照指纹图谱相似度达0.90以上。根据聚类分析结果,野生金银花样品可分为4个分支,其中洛南石坡、巡检、灵口、景村4地金银花聚为一支,河南灵宝的2份样品为一支,丹凤县铁峪铺、武关、蔡川、留仙坪4地样品为一支,丹凤县花瓶子、竹林关2地样品为一支;树型金银花样品也可分成4个分支,其中陕南各地样品为一支;渭南蒲城、西安鄠邑、河南灵宝3地各为1支。野生金银花样品中的绿原酸、异绿原酸、木犀草苷3种成分平均含量分别为3.72%,0.39%,0.15%,树型金银花样品分别为3.42%,1.22%,0.06%。【结论】利用对照指纹图谱可快速鉴别树型金银花与野生金银花;野生金银花的化学物质较树型金银花丰富,但后者因是规范的人工栽培品种,品质更稳定,更符合药品质量稳定性、均一性的要求。

创伤性眶上裂综合征(TSOFS)是由颅底创伤后眶上裂内神经受卡压引起的临床症候群,眶上裂内受压的颅神经如不行手术减压,眼睑下垂、复视及眼球运动障碍等症状会长时间存在,严重影响患者的生活质量。由于其整体发病率不高、不被广大神经外科医师熟悉,部分TSOFS可能合并颅底血管损伤,如未处理血管损伤而先行眶上裂减压手术可能造成大出血,严重者可致残甚至危及生命。目前,国内外尚无可参考的TSOFS诊治的相关共识或指南。为提高临床医师对TSOFS的认识水平、建立规范的诊治的方案,中国医师协会神经修复学专业委员会颅底创伤学组、中华医学会神经外科学分会神经创伤学组、中华医学会创伤学分会神经创伤学组和《中华创伤杂志》编辑委员会组织相关专家,遵循循证医学证据、结合临床诊治经验,制订《创伤性眶上裂综合征诊治中国专家共识(2024版)》,对TSOFS的诊断、分型、治疗、疗效评估与随访等方面提出12条推荐意见,为各级医院神经外科医师规范TSOFS的诊治提供参考。
