目的 观察自拟温润方治疗风寒袭肺型急性咳嗽病的临床疗效。方法 64例风寒袭肺型急性咳嗽病患者,随机分为对照组(31例)和治疗组(33例)。对照组患者给予复方甘草口服溶液治疗,治疗组患者给予温润方治疗。比较两组患者治疗前和治疗3、6 d后的中医症状评分以及临床疗效。结果 治疗3、6 d后,两组患者咳嗽、咯痰、恶风、咽痒、鼻塞、流涕、鼻干、口干咽燥症状评分均低于治疗前,差异均具有统计学意义(P<0.05)。治疗组患者治疗3 d后咳嗽、咽痒、鼻干、口干咽燥症状评分分别为(2.18±0.98)、(1.15±0.81)、(0.60±0.61)、(0.81±0.71)分,均低于对照组的(3.04±1.62)、(1.68±0.96)、(0.96±0.67)、(1.37±0.86)分,差异均具有统计学意义(P<0.05);治疗组患者治疗6 d后咳嗽、咽痒、鼻干、口干咽燥症状评分分别为(0.54±0.51)、(0.42±0.48)、(0.40±0.46)、(0.47±0.51)分,均低于对照组的(1.12±0.76)、(1.11±0.98)、(0.88±0.98)、(1.01±0.92)分,差异均具有统计学意义(P<0.05)。两组患者治疗3、6 d后咯痰、恶风、鼻塞、流涕症状评分比较,差异无统计学意义(P>0.05)。治疗3 d后,治疗组治疗总有效率90.9%高于对照组的71.0%,差异具有统计学意义(P<0.05)。治疗6 d后,治疗组患者治疗总有效率93.9%与对照组的90.3%比较,差异无统计学意义(P>0.05)。结论 在风寒袭肺型急性咳嗽病治疗中,温润方在缓解咳嗽以及部分次症方面明显优于复方甘草口服溶液,起效更快。     

Association Between Clinical Tumor Burden and Efficacy of Immune Checkpoint Inhibitor Monotherapy for Advanced Non–Small-Cell Lung Cancer

BackgroundProgrammed cell death 1 (PD-1) inhibitors have become a standard treatment, albeit not completely effective, for patients with advanced non–small-cell lung cancer (NSCLC). Previous studies of advanced melanoma have revealed that the tumor burden predicted the response to PD-1 inhibitors, although this relationship has remained unclear for NSCLC.Patients and MethodsThe present single-center retrospective study evaluated 163 patients with advanced NSCLC who had received PD-1/programmed cell death ligand 1 (PD-L1) inhibitor monotherapy from December 2015 to December 2018. The clinical tumor burden was estimated using the baseline sum of the target lesions’ longest diameters (BSLDs), measured according to the Response Evaluation Criteria for Solid Tumors, and the baseline number of metastatic lesions (BNMLs).ResultsThe optimal cutoff values for predicting progression-free survival (PFS) were 5 for the BNMLs and 76 mm for the BSLDs, using the minimum P value method. The low-BNML group included 73 patients (44.8%). The median PFS was 12.2 months in the low-BNML group and 2.8 months in the high-BNML group (hazard ratio, 0.51; P = .0005). The low-BSLD group included 92 patients (56.4%). The median PFS was 9.6 months in the low-BSLD group and 3.4 months in the high-BSLD group (hazard ratio, 0.52; P = .0006). Multivariable analysis revealed that low-BSLD, low-BNML, nonsquamous histologic type and a PD-L1 tumor proportion score of ≥ 50% were independently associated with prolonged PFS.ConclusionsPD-L1 expression and the clinical tumor burden can predict the efficacy of PD-1/PD-L1 inhibitor monotherapy for NSCLC.     

钩虫病感染者免疫球蛋白水平、临床特点及胃肠镜下形态分析

目的分析钩虫病感染者血清免疫球蛋白(Ig)A、IgG、IgM和IgE水平,临床特点及胃肠镜下形态。方法分析16例钩虫病感染者的临床资料,观察患者的临床表现、Ig水平、血常规检查结果、胃肠镜检查结果及治疗结果。结果 16例患者的IgE水平明显高于正常参考上限值;IgA、IgG、IgM水平与正常参考上限值比较,差异不明显。经诊断患者的钩虫分布情况:十二指肠降部8例(50.00%),十二指肠球部5例(31.25%),回肠末端3例(18.75%),升结肠1例(6.25%),其中十二指肠及回肠末端均见钩虫者1例(6.25%)。所有患者均予阿苯达唑片驱虫治疗,治疗后1个月复查见贫血得到纠正,消化道症状得以缓解,复查胃肠镜未见虫体,均治愈。结论钩虫病感染者的IgE水平明显升高,胃肠镜检查是确诊钩虫病的重要手段,尤其是要加强对十二指肠降部的检查,并在确诊后及时给予正规治疗措施。     

新冠肺炎疫情下艾灸防治帕金森病的临床应用分析＊

帕金森病（Parkinson''s disease，PD）是仅次于阿尔茨海默病的世界第二大神经系统退行性疾病，随着老龄化社会的到来，PD患病率呈明显上升趋势。全球爆发的新型冠状病毒肺炎（简称新冠肺炎）是一种急性传染性疾病，严重威胁人们的身体健康和生命安全。PD患者大多为老年人且合并有基础疾病，体质普遍较弱，是新冠肺炎的易感人群，一旦染病则发展为重症的风险很高。中医艾灸疗法在治疗PD及防治疫病方面发挥了很好的辅助治疗效果。通督扶阳灸法联合强壮穴艾灸治疗，既可以帮助PD患者改善临床症状，延缓病情进展，又可以提高机体免疫功能，增强抗病能力而防治新冠肺炎。     

Diagnostic sensitivity of electrophysiology and ultrasonography in ulnar neuropathies of different severity

ObjectiveTo assess the diagnostic performance of electrophysiology and nerve ultrasound in ulnar neuropathies of varying clinical severity in 135 consecutive patients.MethodsClinical severity of ulnar neuropathy was graded on a 4 point scale from very mild (symptoms only) to severe (marked atrophy of intrinsic hand muscles). Sensitivity and localization ability of electrophysiology and nerve ultrasound were assessed for each point of the scale.ResultsUltrasound had higher sensitivity than electrophysiology in clinically very mild (20% and 3% for ultrasound and electrophysiology, respectively) and mild (62% and 47% for ultrasound and electrophysiology, respectively) neuropathies, had greater localizing ability in axonal ulnar neuropathies, and identified nerve hypermobility.Ultrasound nerve cross-sectional area had strong positive correlation with both clinical and electrophysiological severity scores, but with significant overlap across the severity groups.ConclusionThe diagnostic work-up of ulnar neuropathies was improved by using both electrophysiology and ultrasound at all levels of clinical severity. Ultrasound increased the diagnostic yield in very mild and mild neuropathies, localized all the ulnar neuropathies with abnormal non-localizing electrophysiology and identified nerve hypermobility.SignificanceThis is the first detailed analysis of the diagnostic performance of electrophysiology and ultrasound in ulnar neuropathies of varying severity.
