特发性肺纤维化急性加重期证候与血清生物标志物的相关性研究＊

目的 通过分析特发性肺纤维化急性加重期（AE-IPF）患者证候与血清生物标志物的关系，为中医辨证治疗提供参考。方法 采用观察性研究设计，收集2019年3月至2019年11月三个中心的AE-IPF患者76例，其中痰热壅肺证26例、痰浊阻肺证50例，并纳入健康志愿者10例作为对照。采用ELISA测定患者血清CCL18、HMGB1、KL-6、MMP-7、SP-A和SP-D水平，分析与中医证候的相关性。结果 AE-IPF患者血清CCL18、HMGB1、KL-6、MMP-7、SP-A和SP-D水平均显著高于健康对照组。血清CCL18、HMGB1、KL-6、MMP-7和SP-D水平在痰热壅肺证和痰浊阻肺证患者间无显著性差异（P＞0.05），而血清SP-A水平存在显著性差异（P＜0.05）。结论 血清SP-A与AE-IPF证候存在一定的相关性，血清SP-A的浓度升高，与痰热壅肺证关系越密切，反之，血清SP-A浓度降低，则与痰浊阻肺证关系越密切。AE-IPF痰热壅肺证患者的预后可能较痰浊阻肺证患者更差。     

Efficacy of Curcumin in Combination with Intralesional Dexamethasone with Hyaluronidase in the Treatment of Oral Submucous Fibrosis: A Randomized Controlled Trial

Objective: The objective of this study was to determine the efficacy of curcumin in combination with  intralesional dexamethasone with hyaluronidase in the treatment of oral submucous fibrosis (OSF). Methods: This randomized, double blind, parallel design, clinical trial was conducted at B.P. Koirala Institute of Health Sciences, Nepal. Thirty-four patients with clinically diagnosed OSF were randomized into two groups (17 participants in each) with baseline treatment of intralesional dexamethasone with hyaluronidase for 6 weeks for the both. Curcumin (2gm/day) was provided to Group A (Test) and Group B (Control) received placebo. Interincisal mouth opening, tongue protrusion, cheek flexibility and visual analogue scale (VAS) scoring of burning sensation of oral mucosa was recorded at baseline, 6, 8 and 12 weeks follow-up and independent t-test was used to compare the improvements in two groups. Results: On comparing the 6 weeks and baseline values, in Group A and B the mean difference in mouth opening was 8.82±1.33 mm and 5.53±1.17 mm respectively (p<0.001), in cheek flexibility was 2.94±1.02 mm and 1.94±1.24 mm respectively (p=0.02) and in tongue protrusion was 6.23±1.48 and 3.65±1.37 mm respectively (p<0.001). The findings were consistent in the 8 weeks follow-up. In 12 weeks follow-up, on comparing with the baseline values, in Group A and B, the mean difference in mouth opening was 8.71±1.16 mm and 5.35±1.22 mm respectively (<0.001), ), in cheek flexibility was 2.81±1.01 mm and 1.76±1.35 mm respectively (p=0.02) and in tongue protrusion was 6.06±1.48 and 3.35±1.50 mm respectively (p<0.001). Both the arms showed 100% improvement in burning sensation in 6, 8 and 12 weeks follow-up. Conclusion: Curcumin in combination with intralesional dexamethasone with hyaluronidase is efficacious in the treatment of OSF.     

中医药治疗特发性肺纤维化的系统评价再评价＊

目的 对中医药治疗特发性肺纤维化（idiopathic pulmonary fibrosis， IPF）的系统评价（SRs）进行再评价。方法 检索知网、中国生物医学数据库、维普、万方、The Cochrane Library、Web of Science、PubMed和EMbase数据库，纳入中医药治疗IPF的SRs，截止2021年5月。使用AMSTAR 2量表进行方法学质量评价，GRADE系统工具进行结局指标证据质量分级。结果 共纳入28篇文献，试验组除辨证论治外，治疗方法集中在活血化瘀、补肺益气等方面，基本符合治疗法则。结果显示中医药治疗IPF可以提高有效率、增加肺功能、提高PaO₂、增加6WMD、缓解临床症状、提高患者的生活质量等。AMSTAR 2量表评价，所纳入SRs均有多项关键条目不达标，整体方法学质量等级不高。采用GRADE工具进行质量分级，一共234个结局指标，无高等证据质量，整体证据等级不高。结论 中医药对比西医治疗IPF有效且不良反应不明显，但RCT研究和系统评价研究方法质量尚有缺陷，完全按照西医评价指标可能会低估真实结果，未来需要更规范的研究及适合中医的评价指标，对中医药研究的安全性方面关注还有待提高。     

术前SCC与CYFRA21-1在肺鳞癌患者表达上调及临床意义

目的 分析术前SCC、CYFRA21-1与肺鳞癌临床病理特征、预后之间的关系。方法 收集2017年3月~2018年4月在云南省肿瘤医院确诊的肺鳞癌患者100例为观察组，确诊为肺良性肿瘤患者90名为肺良性肿瘤组、以及正常人群90名为健康人群组。通过电化学发光法对SCC、CYFRA21-1两种指标进行检测。检测SCC、CYFRA21-1含量，分析在肺鳞癌中表达的临床意义。结果 SCC、CYFRA21-1在肺鳞癌中比在肺良性肿瘤、健康人群中含量要高，差异有统计学意义（P＜0.001），并且敏感性均高于其他两组；男性患者的SCC、CYFRA21-1含量高于女性患者，差异具有统计学意义（P＜0.05）；SCC、CYFRA21-1含量在年龄≥60岁的含量高于＜60岁患者，差异无统计学意义（P＞0.05）；有吸烟史患者的SCC含量高于无吸烟史患者，差异无统计学意义（P＞0.05）。CYFRA21-1在吸烟史患者中高表达，差异有统计学意义（P＜0.05）；SCC、CYFRA21-1在有淋巴结转移、远处转移、肿瘤直径≥5 cm、病理分期为晚期时高表达，差异具有统计学意义（P＜0.05）；SCC、CYFRA21-1阳性患者OS、PFS比阴性患者短；SCC、CYFRA21-1两者之间呈正相关,相关系数（r）为0.630。结论 SCC、CYFRA21-1在肺鳞癌中表达上调；SCC、CYFRA21-1与性别之间存在某种内在联系；SCC、CYFRA21-1与肺鳞癌的TNM分期呈正相关；SCC、CYFRA21-1阳性患者OS、PFS比阴性患者短；SCC、CYFRA21-1两者之间呈正相关,相关系数（r）为0.630。     

Survival effects of time to surgery for Stage I lung cancer: A population-based study

ObjectivesTo examine the impact of time to surgery (TTS) on survival among patients with stage I non-small cell lung cancer (NSCLC).MethodsAll patients in the Canadian province of Ontario with stage I NSCLC from 2007 to 2017 were included. A logistic regression identified the predictors of TTS and a flexible parametric model estimated survival rates based on TTS.ResultsOver the study period, 6428 patients with stage I NSCLC undergoing surgical resection were identified, of which 62.5% had TTS >28 days. Less than half these patients (40.8%) underwent open resection, with 19.3% undergoing open sublobar and 21.5% undergoing open lobectomy. Adenocarcinoma and squamous cell carcinoma tumors accounted for 33.3% and 22.0% of cases, respectively. The majority (85.6%) of patients lived in urban areas within 50 km of a regional cancer center (76.9%). Variables that predicted TTS >28 days include age and extent of resection. After adjustment for VATS vs. open resection, age, sex, frailty, year of diagnosis, histology of tumor, and extent of resection, the hazard ratio for TTS >28 days was 1.26 (95%CI:1.13–1.40), indicating a 26% increased risk of all-cause mortality (p < 0.0001). The highest 5-year survival was observed for patients with stage I disease undergoing resection within 28 days.ConclusionsThe present study found age and extent of resection to be associated with increased TTS. Importantly, patients with TTS >28 days had reduced long-term survival.
