目的:探索建立带状疱疹后遗神经痛(PHN)风险因素预测模型,并进行PHN高危因素分析.方法:回顾性分析了2017年3月至2021年12月本院收住院治疗的急性期带状疱疹患者,根据是否发生PHN将其分为两组.使用LASSO联合Logistic回归分析建立预测模型,并进行危险因素评价.结果:共有307例患者入选本研究,101例(32.8％)患者出现了PHN.应用LASSO联合Logistic回归分析筛选出以下独立危险因素:年龄≥50岁(OR值3.522,95％CI 1.631～7.606,P=0.001)、合并糖尿病史(OR值2.182,95％CI 1.073～4.438,P=0.031)、急性期皮损面积≥5％(OR值2.756,95％CI 1.426～5.327,P=0.003)、先驱痛(OR值2.233,95％CI 1.216～4.099,P=0.010)、急性期疼痛程度评分(NRS)≥6分(OR值10.724,95％CI 5.549～20.725,P<0.001).结论:年龄≥50岁、合并糖尿病史、急性期皮损面积≥5％、急性期先驱痛、急性期疼痛程度评分(NRS)≥6分为PHN发生的独立危险因素.

通过对照研究桥本甲状腺炎(HT)背景下的甲状腺癌与非HT背景下的甲状腺癌超声图像特征,为HT背景下的甲状腺癌结节的提早发现提供诊断依据.将2018年5月-2021年8月于山东大学第二医院手术并且病理证实的409例甲状腺癌患者纳入研究.按照是否合并HT,分为合并HT组(n=198)和未合并HT组(n=211),比较两组年龄、性别、二维及CDFI超声图像特征,包括大小、位置、边界、形态、钙化、血流等.分析HT对甲状腺癌的图像有无影响.两组在年龄、结节的大小、位置、形态、钙化、血流分级等方面差异无统计学意义(P＞0.05);合并HT组在性别构成、结节边界、毛刺、内部回声特点、纵横比及被膜侵犯方面与未合并HT组差异有统计学意义(P＜0.05).合并HT组中结节边界不清的占比(65.15％)多于未合并HT组(占44.08％)、毛刺占比(30.81％)少于未合并HT组(占63.51％),结节内部回声特点也较未合并HT组更为复杂.HT对甲状腺癌结节的超声图像特征确实有一定影响;HT的背景使甲状腺癌结节更加复杂,结节边界不清,毛刺边缘、纵横比不典型及内部回声多样性大大增加了其诊断难度,这也为HT背景下甲状腺癌的诊断提供了新的思路.

Objective To develop an easy‐to‐use nomogram for discrimination of malignant thyroid nodules and to compare diagnostic efficiency with the Kwak and American College of Radiology (ACR) Thyroid Imaging, Reporting and Data System (TI‐RADS). Study Design Retrospective diagnostic study. Setting The Second Hospital of Shandong University. Subjects and Methods From March 2017 to April 2019, 792 patients with 1940 thyroid nodules were included into the training set; from May 2019 to December 2019, 174 patients with 389 nodules were included into the validation set. Multivariable logistic regression model was used to develop a nomogram for discriminating malignant nodules. To compare the diagnostic performance of the nomogram with the Kwak and ACR TI‐RADS, the area under the receiver operating characteristic curve, sensitivity, specificity, and positive and negative predictive values were calculated. Results The nomogram consisted of 7 factors: composition, orientation, echogenicity, border, margin, extrathyroidal extension, and calcification. In the training set, for all nodules, the area under the curve (AUC) for the nomogram was 0.844, which was higher than the Kwak TI‐RADS (0.826, P =. 008) and the ACR TI‐RADS (0.810, P <. 001). For the 822 nodules >1 cm, the AUC of the nomogram was 0.891, which was higher than the Kwak TI‐RADS (0.852, P <. 001) and the ACR TI‐RADS (0.853, P <. 001). In the validation set, the AUC of the nomogram was also higher than the Kwak and ACR TI‐RADS ( P <. 05), each in the whole series and separately for nodules >1 or ≤1 cm. Conclusions When compared with the Kwak and ACR TI‐RADS, the nomogram had a better performance in discriminating malignant thyroid nodules.

目的:研究早期浸润性乳腺癌腋窝淋巴结(ALN)转移与术前MRI及相应临床病理特征的相关性分析.方法:回顾性收集2007年5月-2014年12月在中山大学肿瘤防治中心影像科术前行乳腺MRI检查的507例浸润性乳腺癌患者资料,包括相应临床病理及MRI特征,将ALN分为无转移(N0)及有转移(N+)两组,利用单因素及Logistic回归分析淋巴结转移的相关危险因素,绘制受试者工作特征(ROC)曲线评价其诊断效能.结果:368例患者纳入研究,其中254例患者腋窝淋巴结无转移,114例患者出现腋窝淋巴结转移.将有可能影响ALN转移的因素行单因素分析结果显示,病理分级(P=0.008)、脉管侵犯(P＜0.001)、T分期(P=0.021)、肿瘤位置(P=0.042)、肿瘤大小(P=0.001)、瘤周水肿(P＜0.001)与早期浸润性乳腺癌ALN转移相关(P＜0.05).行二分类Logistic回归分析显示病理分级(P=0.02)、脉管侵犯(P＜0.001,OR=4.495)、瘤周水肿(P＜0.001,OR=3.019)是早期浸润性乳腺癌ALN转移的独立危险因素.根据上述Logistic回归分析建立Logistic回归模型,并绘制ROC曲线,曲线下面积为0.762(95％CI为0.710～0.814,P＜0.001),当约登指数为最大值时,多因素联合诊断早期浸润性乳腺癌ALN转移的最佳截点值为0.260,敏感度为76.8％,特异度为63.9％,诊断效能中等.结论:早期浸润性乳腺癌ALN转移可能与病理分级、脉管侵犯、T分期、肿瘤位置、肿瘤大小、瘤周水肿有关;病理分级、脉管侵犯及瘤周水肿是其独立危险因素,ROC曲线显示术前MRI及临床病理特征多参数联合诊断对早期浸润性乳腺癌ALN转移有较高的诊断价值.

BACKGROUND The diagnostic specificity of conventional ultrasound for breast non-mass lesions (NMLs) is low at approximately 21%-43%. Shear wave elastography (SWE) can distinguish benign from malignant lesions by evaluating the internal and peripheral stiffness. SWE has good reproducibility and high diagnostic efficacy. However, there are very few independent studies on the diagnostic value of SWE in breast NMLs. AIM To determine the value of SWE in the differential diagnosis of breast NMLs. METHODS This study enrolled a total of 118 patients with breast NMLs who underwent SWE examinations in the Beijing Shijitan Hospital Affiliated to Capital Medical University and The Second Hospital of Shandong University from January 2019 to January 2020. The internal elastic parameters of the lesions were recorded, including maximum (Emax), mean (Emean) and minimum elastic values and the standard deviation. The following peripheral parameters were noted: Presence of a "stiff rim" sign; Emax, and Emean elasticity values within 1 mm, 1.5 mm, 2 mm, 2.5 mm and 3 mm from the edge of NMLs. The receiver operating characteristic curve of each parameter was drawn, and the areas under the curve were calculated. RESULTS Emax, Emean and elastic values, and the standard deviation of the internal elastic values in malignant NMLs were significantly higher than those in benign NMLs (P< 0.05). The percentage with the "stiff rim" sign in malignant NMLs was significantly higher than that in the benign group (P< 0.05), and Emax and Emean at the shell of 1 mm, 1.5 mm, 2 mm, 2.5 mm and 3 mm in the malignant group were all higher than those in the benign group (P< 0.05). Of the surrounding elasticity values, Emax of the shell at 2.5 mm in malignant NMLs had maximum areas under the curve of 0.900, and the corresponding sensitivity and specificity were 94.57% and 85.86%, respectively. CONCLUSION The "stiff rim" sign and multiple quantitative elastic values within and around the lesion had good diagnostic performance in the differential diagnosis of breast NMLs. Emax in peripheral tissue had better diagnostic efficiency than other parameters.

BACKGROUND The Rex shunt was widely used as the preferred surgical approach for cavernous transformation of the portal vein (CTPV) in children that creates a bypass between the superior mesenteric vein and the intrahepatic left portal vein (LPV). This procedure can relieve portal hypertension and restore physiological hepatopetal flow. However, the modified procedure is technically demanding because it is difficult to make an end-to-end anastomosis of a bypass to a hypoplastic LPV. Many studies reported using a recanalized umbilical vein as a conduit to resolve this problem. However, the feasibility of umbilical vein recanalization for a Rex shunt has not been fully investigated. AIM To investigate the efficacy of a recanalized umbilical vein as a conduit for a Rex shunt on CTPV in children by ultrasonography. METHODS A total of 47 children who were diagnosed with CTPV with prehepatic portal hypertension in the Second Hospital, Cheeloo College of Medicine, Shandong University, were enrolled in this study. Fifteen children received a recanalized umbilical vein as a conduit for a Rex shunt surgery and were enrolled in group I. Thirty-two children received the classic Rex shunt surgery and were enrolled in group II. The sonographic features of the two groups related to intraoperative and postoperative variation in terms of bypass vessel and the LPV were compared. RESULTS The patency rate of group I (60.0%, 9/15) was significantly lower than that of group II (87.5%, 28/32) 7 d after (on the 8th d) operation (P < 0.05). After clinical anticoagulation treatment for 3 mo, there was no significant difference in the patency rate between group I (86.7%, 13/15) and group II (90.6%, 29/32) (P > 0.05). Moreover, 3 mo after (at the beginning of the 4th mo) surgery, the inner diameter significantly widened and flow velocity notably increased for the bypass vessels and the sagittal part of the LPV compared to intraoperative values in both shunt groups (P < 0.05). However, there was no significant difference between the two surgical groups 3 mo after surgery (P > 0.05). CONCLUSION For children with hypoplastic LPV in the Rex recessus, using a recanalized umbilical vein as a conduit for a Rex shunt may be an effective procedure for CTPV treatment.
