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.

Objective To study the application of ultrasound elasticity imaging combined thickness analysis of uterine scar in predicting uterine rupture in women pregnant after cesarean section．Methods Pregnant women with vaginal birth after cesarean（VBAC）from January 2020 to December 2021 in Zhongshan Hospital of Traditional Chinese Medicine were selected as the research subjects．A total of 32 VBAC parturients with uterine rupture and 90 VBAC parturients without uterine rupture were included according to the inclusion and exclusion criteria．The basic information of the subjects was queried through the medical record information system of the hospital．In the third trimester（≥37 weeks）,the thickness and elasticity of uterine scar were measured by ultrasound,and the predictive effect of uterine scar thickness and elastic SI value on uterine rupture was analyzed by ROC curve．Results Chi-square test showed that the incidence of uterine rupture was higher in patients with age>35 years,pregnancy>2 times,interval from last cesarean section<2 years,newborn weight≥3kg,and the proportion of uterine rupture in single suture was higher than that in double suture（P<0.05）．The mean uterine scar thickness of 122 subjects was（3.42±0.49）mm,and the mean SI was（2.57±0.45）．The area under curve（AUC）of uterine scar thickness alone for predicting uterine rupture was 0.805（95%CI：0.730-0.880,P<0.05）,the cut off value was 3.05 mm,the sensitivity was 0.726,the specificity was 0.910,and the Youden coefficient was 0.636 by ROC curve analysis．The AUC of uterine scar SI alone for predicting uterine rupture was 0.730（95%CI：0.635-0.824,P<0.05）,the cut off value was 2.11,the sensitivity was 0.767,the specificity was 0.781,and the Youden coefficient was 0.548 by ROC curve analysis．The AUC of uterine scar thickness combination for predicting uterine rupture was 0.874（95%CI：0.812-0.937,P<0.01）,the sensitivity was 0.875,the specificity was 0.811,and the Youden coefficient was 0.686 by ROC curve analysis．The AUC predicted by uterine scar thickness combined with uterine scar SI value was higher than that predicted by uterine scar thickness alone（Z=7.611,P=0.041）and uterine scar SI value（Z=25.864,P=0.025）．Conclusions Elastic SI value of ultrasound imaging of uterine scar combined with uterine thickness can effectively improve the prediction efficiency of ultrasound for VBAC maternal uterine rupture,which has certain application significance,but further demonstration is still needed．

糖尿病已成为全球最严重的健康问题之一。需要白内障手术的糖尿病患者也日益增多,虽然糖尿病的眼表并发症很常见,但由于糖尿病患者全身和眼部疾病十分复杂,使得眼前段如角结膜和泪腺的糖尿病并发症往往被忽视。糖尿病患者白内障超声乳化术有引发或加重眼前节疾病的风险,包括干眼病（DED）、角膜上皮糜烂、上皮缺损迁延不愈,甚至威胁视力的角膜溃疡。这些风险里最为常见的是DED,并且可能因白内障超声乳化手术而加重。眼科医生需要在手术前预先评估已存在的DED是否需要术前治疗,并且需要注意在已存在 DED 的情况下,各项术前检查数据测量的准确性会降低,以及尽可能减少对眼表造成损害的各种手术因素;并考虑通过管理减少术后 DED。本综述就评估白内障超声乳化术对合并糖尿病的老年性白内障患者的眼表术中的影响因素进行分析。

Diabetes mellitus(DM)has become one of the most serious health problems in the world. The number of diabetic patients requiring cataract surgery is also increasing. Although ocular surface complications of DM are common,the complexity of systemic and ocular disease in diabetic patients makes diabetic complications in the anterior segment,such as the cornea and lacrimal gland,often be overlooked. Phacoemulsification in diabetic patients carries the risk of triggering or exacerbating ocular segment disease,including dry eye disease,corneal epithelial erosion,persistent epithelial defects and even vision-threatening corneal ulcers. The most common of these risks is dry eye disease,and it can be exacerbated by cataract phacoemulsification. Ophthalmologists need to preemptively assess the need for preoperative treatment of pre-existing dry eye disease(DED),be aware of the reduced accuracy of preoperative data measurements in the presence of DED,and minimize surgical factors that can damage the ocular surface;and consider management to reduce postoperative DED. In this review,we analyze the factors that influence phacoemulsification in ocular surface surgery for senile cataract patients with diabetes.

Methods The data of 116 elderly patients with PICC catheterization in our hospital from December 2019 to January 2021 were retrospectively analyzed.Patients were divided into implementation group and control group (58 cases each) according to whether they received special preventive nursing for complications of ultrasound-guided PICC catheterization (specialized nursing). The catheterization outcomes and complications of the two groups were compared, the changes in the psychological state were evaluated, and satisfaction rate of the patients was investigated. Results The success rate of the first catheterization, the head-end in place, and ideal placement of the head-end in implementation group were higher than those of the control group, the average number of catheterization and operation time were less than those of the control group, and the differences were statistically significant (P<0.05). The total incidence of various complications in the implementation group was 18.97%, while that in the control group was 46.55%, the difference between two groups was statistically significant (P<0.05). The scores of Self-Rating Anxiety Scale and Self-Rating Depression Scale of the two groups after PICC catheterization were lower than those before catheterization, and the implementation group was lower than the control group, the differences were statistically significant (P<0.05). The total satisfaction rate of patients in the implementation group was 96.55%, and that in the control group was 77.59%, which difference was statistically significant (P<0.05). Conclusion Special preventive nursing measures could improve the catheterization accuracy of ultrasound-guided PICC for elderly patients, reduce the risk of catheter-related complications, relieve the psychological pressure of patients, and improve patients’ satisfaction.

目的 探讨术前超声有关指标在预测腹腔镜胆囊切除术(LC)难易度中的价值,以预判LC手术的风险,减少手术的盲目性。方法 257例术前获得的超声参数包括:胆囊大小、胆囊壁厚度、胆囊黏膜面情况、胆囊内胆汁透声情况、胆囊结石最大直径、胆囊颈部结石嵌顿情况。术后资料包括手术时间、术中出血量、是否放置引流管、是否中转进腹手术、术后并发症。计算257例手术的平均时间并将其称为标准手术时间,将超过标准手术时间的、术中出血≥100 mL、术后放置引流管、中转开腹的手术定义为有难度手术。以此标准将257例手术患者分为容易组和困难组,应用χ²检验进行单因素分析,LC手术困难的危险因素;再对这些指标进行Logistic多元回归分析,确定预测LC难易的独立危险因素。结果 单因素分析,术前超声指标:胆囊大小>50 cm²、胆囊壁厚度>4 mm、胆囊结石最大直径>2 cm、胆囊颈部结石嵌顿、胆囊内胆汁透声差,是LC难度的危险因素。Logistic多元回归分析证实,胆囊大小、胆囊壁厚度、胆囊内胆汁透声差、胆囊颈部结石嵌顿等4项超声检测指标是困难LC的独立危险因素。结论 手术前胆囊超声检查可以客观评估LC难度,对指导术者选择LC病例具有一定的预测价值。

Objective To explore the value of preoperative ultrasound indicators in predicting the difficulty of laparoscopic cholecystectomy (LC), in order to predict the risk of LC surgery and reduce the blindness of surgery. Methods The preoperative ultrasonographic parameters of 257 cases included gallbladder size, gallbladder wall thickness, gallbladder mucosal surface, bile sound transmission in gallbladder, maximum diameter of gallstone, and gallstone incarceration in gallbladder neck. Postoperative data included operation time, intraoperative blood loss, whether drainage tube was placed, whether transfer to abdominal surgery, and postoperative complications. The average operation time of the 257 cases was calculated and called the standard operation time, and the operation that exceeded the standard operation time, intraoperative bleeding ≥100 mL, postoperative drainage tube placing, and conversion of abdominal operation were defined as difficult operation. According to this standard, 257 patients were divided into the easy group and the difficult group. The χ² test was used for univariate analysis to identify the risk factors of difficult LC operation. Logistic multiple regression analysis was performed to determine the independent risk factors for predicting LC difficulty. Results According to unifactor analysis, preoperative ultrasound indicators: gallbladder size >50 cm², gallbladder wall thickness >4 mm, maximum diameter of gallstone >2 cm, gallbladder neck stone incarceration, and poor bile ultrasound transmission in gallbladder were risk factors for LC difficulty. Logistic multiple regression analysis confirmed that gallbladder size, gallbladder wall thickness, poor bile ultrasound transmission in gallbladder and stone incarceration in gallbladder neck were independent risk factors for difficult LC. Conclusions Ultrasound examination of gallbladder before operation could objectively evaluate the difficulty of LC, and had certain predictive value for guiding the surgeon to select LC cases.

Objective To evaluate the value of ultrasonography scoring system in differential diagnosis of well-differentiated liposarcomas (WDLPS) and benign lipoma (LP), and to provide evidence for the differential diagnosis and treatment choice. Methods Fourteen WDLPS cases (total of 15 masses) and 37 LP cases (total of 40 masses) were diagnosed by surgical histopathology, which clinical data and the ultrasound images were analyzed retrospectively. The parameters including age, gender, region, mass length, length/width ratio, shape, margin, envelope echoes, echogenicity, texture, location, blood flow were compared between the groups above. A scoring system was established by analyzing the parameters with statistical differences, and the ROC curve was plotted to calculate the best cut-off value and evaluate the diagnostic efficiency of the scoring system. Results There were statistically significant differences between two groups in the following six parameters: age, mass length, length/width ratio, envelope echoes, location, blood flow(P＜0.05). The scoring system was established by assigning 0 or 1 point to each factor, and the total score was 0～6 points. The highest diagnostic efficiency of WDLPS was observed at the cut-off value ≥ 3. The sensitivity, specificity, accuracy, the positive predictive value and the negative predictive value was 86.7%, 77.5%, 80%, 59.1%, 93.9% respectively. Conclusions The ultrasonography-based scoring system has a better diagnostic efficacy in differentiating WDLPS and LP, which can provide an important reference basis for the selection of clinical treatment, and is worthy of promotion and application.

Objective To compare the efficacy and safety of remimazolam tosilate and propofol in painless ultrasonic gastroscopy. Methods In a randomized, single-blind controlled study, 60 patients undergoing ultrasonic gastroscopy were selected and divided into observation group (31 cases) and control group (29 cases). Observation group was anesthetized with remimazolam tosilate, while control group was anesthetized with propofol. Two groups' hemodynamic index, perioperative adverse events, changes of MOAA/S score, awakening and departure time were observed at different time points during anesthesia. Results The observation group had less changes on hemodynamics. The observation group had enough depth of sedation, while the control group had a deeper degree of sedation. The onset time of the two groups was similar and both awoke quickly and left, but the awakening time and leaving time in the observation group were slightly shorter. Adverse events in the control group were more than those in the observation group. Conclusions Remimazolam tosilate for painless ultrasonic gastroscopy had little effect on hemodynamics, which can generate enough depth of sedation, and make patients wake up quickly. In addition, the incidence of its adverse events was low, and the overall effectiveness and safety were superior to those of propofol.

目的 探究超声检查对于甲状腺囊性结节随访中的作用和临床价值,探讨其临床应用意义。方法 以2018年1月—2019年1月在本院就诊,经过临床金标准诊断为甲状腺囊实性结节的83名患者作为研究对象,采用历史性队列研究方法对患者进行为期18个月的随访观察,对患者在随访期内,使用超声检查所得知的甲状腺囊实性结节的大小、形态、边界、内部回声、钙化及血流信号等特征进行记录,并与患者初次就诊时的记录进行对比分析。结果 根据随访记录得知,83例患有甲状腺囊实性结节的患者当中,75例患者在随访后发现具有甲状腺恶性结节症,其余8例患者不具有甲状腺恶性结节特征。随访后83例患者的甲状腺囊实性结节均呈现好转,主要表现为:甲状腺囊实性结节出现不同程度的吸收;结节体积减小,个数无变化;结节吸收后在超声下显示在同一部位的结节表现为低或极低回声结节;囊性液体成分明显减少,部分原结节较小的患者,囊性成分出现消失。根据对随访前后患者甲状腺囊实性结节的平均体积对比有统计学差异(P<0.05),随访后的结节半径明显小于随访前。甲状腺囊实性结节体积有效缩小率为68%～88%。结论 通过对甲状腺囊实性结节定期进行超声复查可以实现对甲状腺结节的动态观察,有助于对患者的病情进行掌握,且由于甲状腺囊实性结节患者在后期结节吸收过程中常常出现恶性结节特征。通过使用超声检查对患者进行长期随访不仅可起到早期诊断甲状腺恶性肿瘤的意义,还可以避免,因过度诊断为甲状腺恶性结节,而使用细胞穿刺检查等有创检查对患者造成的不便。
