基于“祛邪为第一要义”从清热化湿论治新型冠状病毒肺炎

结合验案分析,基于"祛邪为第一要义"探讨新型冠状病毒肺炎从清热化湿论治的思路与方法。认为新型冠状病毒肺炎主要是属于"湿热"性质的疫病,治疗应强调清热化湿,以"祛邪为第一要义",辅以扶正。在中医祛邪与扶正理论指导下,通过宣肺平喘、通腑泻热、芳香化湿等治法,祛邪为主,肺肠合治,可以使发热减轻或消退,使大便通畅,从而截断病情进展,避免或减少危重症的发生及死亡的风险;通过清热化湿、疏肝健脾、凉血化瘀等治法,祛邪兼以扶正,肺与肝、脾合调,可以改善肝功能损伤,减少病情加重的风险;通过补气健脾等扶正治法,可以改善患者的精神和体力,促使病毒更快转阴,缩短病程,促进患者早日康复。     

Racial differences in characteristics and prognoses between Asian and white patients with nonsmall cell lung cancer receiving atezolizumab: An ancillary analysis of the POPLAR and OAK studies

This study aimed to compare the differences in characteristics and prognoses between Asian and white patients receiving immunotherapy for nonsmall cell lung cancer (NSCLC). We studied 390 patients who received atezolizumab as part of the POPLAR or OAK trial, and analyzed the differences in baseline characteristics, outcomes and genetic mutations in blood samples between Asian and white patients. Overall survival (OS) was longer in Asian compared to white patients (median OS: 18.7 vs. 11.1 months; p = 0.005). Race was identified as an independent prognostic factor for OS (Asian vs. white: hazard ratio 0.647, 95% confidence interval 0.447–0.936, p = 0.021), together with performance status, histology, baseline sum of the longest tumor diameters (BLSLD) and number of metastatic sites. The two groups also differed in terms of characteristics including smoking history, BLSLD, epidermal growth factor receptor (EGFR) mutation frequency, programmed death-ligand 1 expression and blood-based tumor-mutation burden. Blood mutations of STK11, EGFR, KEAP1, POLE, GRM3, ATM and STAG2 were associated with treatment response, and TP53, KEAP1, APC, RB1, CREBBP, EPHA5 and STAG2 mutations were associated with OS. The blood-based mutation profiles differentiated between Asian and white patients, especially in relation to EGFR (23.8 vs. 8.5%), TP53 (30.2 vs. 46.9%) and STK11 (1.6 vs. 12.3%) mutations (all p < 0.05). The different clinicopathological features and mutation profiles in Asian and white patients may explain the superior outcome following atezolizumab treatment in Asian patients with NSCLC. The results of this study have important implications for further studies on racial disparities in relation to immunotherapy.     

肺癌靶向治疗研究:以文献计量学和可视化分析描述的热点与趋势

目的:通过文献计量学分析方法，阐述并分析肺癌靶向治疗的研究热点与趋势。方法:文章检索了万方数据库、Web of Science、SooPAT(中国专利)数据库近10年来国内外肺癌靶向治疗的相关文献，以文献计量学方法，分析并归类了肺癌靶向治疗的研究热点与时效变迁的趋势。结果:在万方数据库3 744篇肺癌靶向治疗的中文文章中，发现作用于表皮生长因子受体基因突变位点的分子靶向药物-吉非替尼治疗非小细胞肺癌的研究是中国学者近10年的主要研究热点；在近10年Web of Science数据库中检索到的810篇英文文章及参考文献显示，西妥昔单抗、贝伐单抗、纳武单抗、吉非替尼、厄洛替尼和环唑替尼为这10年肺癌治疗领域靶向治疗的热点药物，而多种靶向药物的联合治疗、晚期非小细胞肺癌的靶向治疗效果和肺癌靶向治疗后的脑转移也成为近5年该领域的国际关注热点；中国肺癌靶向治疗领域的254项有权专利的分析显示，申报了专利的主要药物包括酸敏感的吉非替尼-氟硼二吡咯衍生物、顺铂抗肺癌主动靶向隐形类脂质体等。结论:文章采用文献计量学的量化分析技术，呈现出近10年肺癌靶向治疗已成为该领域专业研究者持续关注的热点，而如何选择正确的靶向药物或药物组合方案来解决肺癌治疗中的耐药性问题，同时最大程度地减少患者的不良反应，以延长患者的生存率，应是未来集中研究的方向。     

单孔胸腔镜下肺癌术后胸腔引流时间的影响因素分析北大核心

目的:探讨单孔胸腔镜下肺癌手术术后胸腔引流时间的影响因素。方法:本研究采用回顾性分析方法,回顾我院2018年01月至2019年12月原发性肺癌患者经单孔胸腔镜手术治疗的病例199例。按照术后胸腔引流时间分为两组,Ⅰ组(术后胸腔引流时间<5天)和Ⅱ组(术后胸腔引流时间≥5天)。对于影响术后胸腔引流时间的可能因素在两组间先采用单因素分析的方法筛选,再将筛选出来的对术后胸腔引流时间可能有意义的影响因素进行二项Logistic多因素回归分析。结果:经单因素分析及二项Logistic多因素回归分析结果显示:年龄≥60岁、手术部位、肺段切除术、胸膜粘连、手术时间≥180 min、术后早期下床活动是术后胸腔引流时间的独立影响因素(P<0.05)。结论:对于具有多个延长术后胸腔引流时间的独立影响因素的患者,应制定个体化管理方案,尽可能减少术后胸腔引流时间,减少住院天数,加快患者康复。     

子宫内膜功能亢进性疾病的“异病同治”诊治研究思路＊

笔者根据现代临床子宫内膜的病理演变过程结合中医“异病同治”理念，提出“子宫内膜功能亢进性疾病”概念，涵盖5种常见的子宫内膜疾病：无排卵性异常子宫出血（Abnormal Uterine Bleeding Ovulatory dysfunction，AUB-O），子宫内膜息肉（Endometrial Polyp，EP），子宫内膜异位症（Endometriosis，EMs），子宫腺肌病（Adenomyosis，AM），子宫内膜癌（Endometrial Carcinoma，EC）。基于文献的汇总，分析得到此类疾病的子宫内膜病理演变与中医病因病机的关联性，为寻找关键通路、创新性治疗此类疾病提供了重要的参考方向，对深化中医妇科学常见疾病的共性病因病机提供了理论依据和探索思路。     

Vaccines and autoimmunity during the COVID-19 pandemic

To control the pandemic, efficient vaccines must be applied to the population, including patients with autoimmune diseases. Therefore, one can expect that coronavirus disease 2019 (COVID-19) vaccines may influence the underlying autoimmune processes in these patients. Additionally, it is essential to understand whether COVID-19 vaccines would be effective, safe, and provide long-lasting immunological protection and memory. However, the currently available and approved COVID-19 vaccines turned out to be safe, effective, and reliable in patients with autoimmune inflammatory and rheumatic diseases. Furthermore, most patients said they felt safer after getting vaccinations for COVID-19 and reported enhanced overall quality of life and psychological wellbeing. In general, the COVID-19 vaccines have been highly tolerated by autoimmune patients. Such findings might comfort patients who are reluctant to use COVID-19 vaccines and assist doctors in guiding their patients into receiving vaccinations more easily and quickly.
