目的 应用高频超声观察眼轮匝肌的解剖信息和动态特征,探究肉毒毒素注射前超声评估的可行性,为个体化、精准化的治疗提供可能,以实现更加安全、更加高效的治疗效果。方法 采用高频超声获取40名20~30岁健康志愿者的双侧80条眼轮匝肌的长轴、短轴切面声像图,观察其全程形态、内部回声,并测量外眦水平眼轮匝肌最外侧缘与外眦之间的距离、外眦水平眼轮匝肌最厚处的前后径、外眦水平眼轮匝肌最厚处与表皮之间的距离,并对数据进行统计学分析。结果 高频超声可以清晰地显示眼轮匝肌全程的走形和整体肌束结构。微笑时可见外眦外侧的眼轮匝肌向内收缩,并出现不同程度的增厚。男性和女性外眦水平眼轮匝肌最外侧缘与外眦之间的距离分别为左侧（27.50±2.58）（25.32±2.17）mm,右侧（27.35±2.15）（25.11±2.08）mm;外眦水平眼轮匝肌最厚处的前后径分别为左侧（1.055±0.209）（0.770±0.172）mm,右侧（1.010±0.171）（0.775±0.162）mm;外眦水平眼轮匝肌最厚处与表皮之间的距离分别为左侧（2.450±0.274）（2.860±0.375）mm,右侧（2.430±0.252）（2.825±0.424）mm。上述3种指标在左右侧对比差异无统计学意义（P>0.05）。与男性对比,女性外眦水平皮下组织较厚、眼轮匝肌较薄,其最外侧缘与外眦之间的距离较短（P<0.05）。结论 高频超声为观察青年人群眼轮匝肌结构的有效影像学工具,可用于肉毒毒素注射前的面部评估。

Objective To observe the anatomical information and dynamic characteristics of the orbicularis oculi muscle by high-frequency ultrasound,to explor the feasibility of ultrasound evaluation before botulinum toxin injection,and to provide the possibility for personalized and precise treatment to achieve safer and more efficient therapeutic effects．Methods High frequency ultrasound was used to obtain long axis and short axis sectional ultrasound images of 80 bilateral orbicularis oculi muscles from 40 healthy volunteers aged 20-30．The overall morphology and internal echoes were observed,and the distance between the outermost edge of the orbicularis oculi muscle and the outer canthus,the anterior posterior diameter of the thickest part of the orbicularis oculi muscle at the outer canthus level,and the distance between the thickest part of the orbicularis oculi muscle and the epidermis at the outer canthus level were measured．Statistical analysis was performed on the data．Results High frequency ultrasound can clearly display the entire course of the orbicularis oculi muscle and the overall muscle bundle structure．When smiling,the orbicularis oculi muscle on the outer side of the outer canthus can be seen to contract inward and show varying degrees of thickening．The distance between the outermost edge of the orbicularis oculi muscle and the outer canthus of males and females were（27.50±2.58）（25.32±2.17）mm on the left side and（27.35±2.15）（25.11±2.08）mm on the right side,respectively．The anterior posterior diameters of the thickest part of the orbicularis oculi muscle at the level of the outer canthus were left（1.055±0.209）（0.770±0.172）mm and right（1.010±0.171）（0.775±0.162）mm,respectively．The distance between the thickest part of the orbicularis oculi muscle at the level of the outer canthus and the epidermis were（2.450±0.274）（2.860±0.375）mm on the left side and（2.430±0.252）（2.825±0.424）mm on the right side．There was no statistically significant difference in the comparison of the above three indicators on the left and right sides（P>0.05）,while there was a statistically significant difference in the mean values of both males and females（P<0.05）．Compared with males aged 20-30,females had thicker subcutaneous tissue at the level of the outer canthus and thinner orbicularis oculi muscle,with a shorter distance between the outermost edge and the outer canthus． Conclusions High frequency ultrasound is an effective imaging tool for observing the structure of the orbicularis oculi muscle in young population,and can be used for facial assessment before botulinum toxin injection．

目的 探讨气道径向超声(RP-EBUS)引导多维度联合检查对周围型肺癌的诊断价值。方法 选取2019年9月—2021年12月于佛山市第二人民医院确诊的74例周围型肺癌患者,分析RP-EBUS引导肺活检、支气管黏膜刷检、支气管肺泡灌洗细胞学及DNA甲基化检测等多维度联合检查对周围型肺癌的诊断阳性率及影响因素。结果 RP-EBUS引导肺活检、支气管黏膜刷检、支气管肺泡灌洗液细胞学、DNA甲基化检测对周围型肺癌的诊断阳性率分别为52.7%、47.3%、45.9%和51.4%,RP-EBUS引导多维度联合检查阳性率为71.6%,高于单一方法检查(P<0.05);RP-EBUS引导多维度联合检查病灶直径≥30 mm诊断阳性率高于病灶直径＜30 mm (82.9% vs 57.6%),差异有统计学意义(P<0.05);RP-EBUS引导多维度联合检查在肺上叶、中叶/舌叶、下叶病灶的阳性率分别为69.7%、66.7%和76.9%,差异无统计学意义(P>0.05);联合检查中超声探及病灶的诊断阳性率高于超声未探及病灶(76.9% vs 33.3%),差异有统计学意义(P<0.05);病灶超声图像表现为中心均实型的联合检查诊断阳性率高于非中心均实型(86.0% vs 59.1%),差异有统计学意义(P<0.05)。结论 RP-EBUS引导多维度联合检查对周围型肺癌有更高的诊断阳性率,诊断阳性率与病灶大小、超声是否探及病灶及病灶超声图像特征有关,与病灶部位无关。

Objective To investigate the value of radial probe endobronchial ultrasound (RP-EBUS)guided multi-dimensional combined examination in the diagnosis of peripheral lung cancer. Methods A retrospective analysis of 74 patients with peripheral lung cancer which were diagnosed in Foshan Second People's Hospital from September 2019 to December 2021 was carried out. RP-EBUS guided biopsy, brushing biopsy, bronchus alveolar lavage cytology and DNA methylation detection results were analyzed to obtain the positive diagnosis rate and influencing factors. Results The positive rates of RP-EBUS guided biopsy, brushing biopsy, bronchus alveolar lavage cytology and methylation for peripheral lung cancer were 52.7%, 47.3%, 45.9% and 51.4%, respectively. The positive rate of RP-EBUS guided multi-dimensional combined detection was 71.6%, which was significantly higher than single detection (P<0.05). The positive rate of RP-EBUS multi-dimensional combined examination in lesions diameter ≥30 mm was higher than that of lesion diameter ＜30 mm (82.9% vs 57.6%, P<0.05). The positive rate of RP-EBUS guided multi-dimensional combined group in the upper lobe, middle lobe/lingual lobe, and lower lobe of the lung were 69.7%, 66.7% and 76.9%, respectively, with no significant difference (P>0.05). The positive rate of ultrasound detected lesion in combined group was higher than that of undetected lesions (76.9% vs 33.3%, P<0.05). The ultrasound images of solid center lesions had higher positive rates than that of non solid center lesions (86.0% vs 59.1%, P<0.05). Conclusions RP-EBUS guided multi-dimensional combined examination has a higher positive rate for diagnosis of peripheral lung cancer. The positive rate of diagnosis are related to the size of the lesion, whether the lesion is detected by ultrasound and the characteristics of the ultrasound image of the lesion, but not related to the location of the lesion.

目的 探讨肺部超声(LUS)在高龄(≥75 岁)感染新型冠状病毒肺炎(COVID-19)患者中的应用及后续对病程的监测及诊断价值。方法 回顾性分析2022年11月1日—2023年1月15日本院内科收治的25例COVID-19高龄患者进行病例归纳总结,除临床资料外,动态监测肺部超声检查情况,并与肺CT结果对比,观察检查结果,以及对病程转归的预判及影响。结果 LUS检查提示患者出现不同程度肺间质损伤,包括离散型B线(间质渗出)或融合型B线(渗入肺泡)以及肺实变(肺泡萎陷)。随着病情好转,LUS可见肺实变范围缩小,B线逐步稀疏到消散,A 线出现。结论 LUS与同期胸部CT结果一致性良好。LUS检查安全简便,重复性好,可实时动态监测,即可作为初筛手段,亦可运用于特殊人群,协助临床治疗决策。

Objective To explore the application and follow-up monitoring and diagnostic value of lung ultrasound (LUS) in elderly patients(≥75y) with novel coronavirus pneumonia (COVID-19). Methods Data of 25 COVID-19 elderly patients admitted to the Department of Internal Medicine from November 1, 2022 to January 15, 2023 were retrospectively analyzed and summarized. In addition to clinical data, dynamic monitoring of LUS was performed, and the results were compared with lung CT results. The examination results, as well as the prediction and impact on the course of disease were observed. Results LUS imaging indicated that patients had different degrees of interstitial lung injury, including discrete type B line (interstitial exudation) or fusion type B line (alveolar infiltration) and lung consolidation (alveolar collapse). With the improvement of the disease, the range of lung consolidation seen in LUS was reduced, the B-line was gradually sparse to dissipate, and the A-line appeared. Conclusions The results of LUS and chest CT in the same period are consistent. LUS examination is safe, simple, reproducible, and can be monitored dynamically in real time. It can be used as a primary screening method, and also be used in special patients to assist clinical treatment decision-making.
