浅谈不同年龄结节性甲状腺肿合并甲状腺癌患者甲状腺超声特征的临床比较

目的:给予不同年龄结节性甲状腺肿合并甲状腺癌患者实施甲状腺超声检查,对相应的超声检查特征展开分析。方法:选择2018年6月~2019年6月的114例患者为对象,所有患者均被确诊为结节性甲状腺肿合并甲状腺癌,并且利用甲状腺二维超声及多普勒超声对患者进行检查,依据患者年龄阶段均分为两组,每组中各纳入57例患者,年龄超过60岁以上的患者为老年组;年龄在60岁以下的患者为中青年组,对比两组患者的血流相关指标与钙化情况数据。结果:老年组中的平均收缩期流速、阻力指数等数据明显低于中青年组,且比较后P<0.05,具有临床可比较意义。老年组中钙化的总例数为21例,总钙化率占比为36.84%,中青年组中钙化的总例数为38例,总钙化率占比为66.67%,前者数据显著低于后者钙化率,P<0.05。结论:在对结节性甲状腺肿合并甲状腺癌患者实施超声检查后,中青年组患者的病灶呈现低回声、高回声以及伴微小钙化、血流分布以内部血流为主、血流阻力大的特点明显高于老年组,能够显著提升诊断效果,为日后的临床治疗提供了图像依据。     

Preoperative comprehensive malignancy risk estimation for thyroid nodules: Development and verification of a network-based prediction model

BackgroundIn order to avoid excessive treatment of thyroid nodules in the clinic, it is necessary to find a simple and practical analysis method to comprehensively and accurately reflect benign or malignant thyroid nodules. This study aimed to construct and validate a comprehensive and reliable network-based predictive model using a variety of imaging and laboratory criteria for thyroid nodules to stratify the risk of malignancy prior to surgery.MethodsWe retrospectively analyzed data from patients who underwent surgical treatment for thyroid nodules at the Thyroid and Breast Diagnosis and Treatment Center of Weifang Hospital of Traditional Chinese Medicine between January 2018 and December 2020. Binary logical regression analysis was performed to predict whether nodules were malignant or benign. The developmental dataset included 457 patients (January 2018–December 2020). The validation set included separate data points (n = 225, January 2018–December 2020).ResultsIn this study, criteria that showed significant predictive value for malignant nodules included TI-RADS: 4b (p = 0.065); Bethesda IV, Bethesda V, Bethesda VI (P < 0.0001); BRAF^V600E mutation (P < 0.0001); Calcitonin>5 pg/ml (p = 0.0037); and FNA-Tg>30 ng/ml (p = 0.0003). A 10-grade risk scoring system was developed. The risk of malignancy risk ranged from 2.06% to 100% and was positively associated with increasing risk grade. The areas under the receiver-operating characteristic curve of the development and validation sets were 0.972 and 0.946, respectively.ConclusionA simple, comprehensive and reliable web-based predictive model was designed using a variety of imaging and laboratory criteria to stratify thyroid nodules by probability of malignancy.

Go-Ichi-Ni-San 2: A potential biomarker and therapeutic target in human cancers

Cancer incidence and mortality are increasing globally, leading to its rising status as a leading cause of death. The Go-Ichi-Ni-San (GINS) complex plays a crucial role in DNA replication and the cell cycle. The GINS complex consists of four subunits encoded by the GINS1, GINS2, GINS3, and GINS4 genes. Recent findings have shown that GINS2 expression is upregulated in many diseases, particularly tumors. For example, increased GINS2 expression has been found in cervical cancer, gastric adenocarcinoma, glioma, non-small cell lung cancer, and pancreatic cancer. It correlates with the clinicopathological characteristics of the tumors. In addition, high GINS2 expression plays a pro-carcinogenic role in tumor development by promoting tumor cell proliferation and migration, inhibiting tumor cell apoptosis, and blocking the cell cycle. This review describes the upregulation of GINS2 expression in most human tumors and the pathway of GINS2 in tumor development. GINS2 may serve as a new marker for tumor diagnosis and a new biological target for therapy.     

左右半结肠癌病理特征及治疗新策略研究进展

结肠癌患者预后较差，全身系统治疗为目前常用基本策略。近年来的相关研究证据表明，发生在左半结肠和右半结肠的肿瘤病理学特征、分子发病机制及预后存在差异。目前对左、右半结肠癌之间存在的这种异质性差异尚无明确的区分对待策略，国内外指南也尚无定论，因而研究其临床病理特征及相关预后差异具有重要临床意义。笔者在复习相关文献的基础上，就此作一综述。     

左、右半结肠癌骨转移病理特征及预后分析

目的:比较左半结肠癌（LSCC）和右半结肠癌（RSCC）骨转移的病理特征和临床预后差异。方法:对漯河市中心医院2007年1月至2015年12月收治的103例结肠癌骨转移病例资料进行回顾性分析，据解剖位置将64例纳入LSCC组，39例纳入RSCC组，对比分析其病理学特征,绘制并分析生存曲线,筛选预后因素。结果:RSCC骨转移相对LSCC表现为:CA199 阳性率高、年龄大、分化程度更差、分期更晚、预后更差。单因素分析结果示原发肿瘤位置、TNM分期、LDH水平、ALP水平是影响结肠癌骨转移3年生存的相关因素。Logistic多因素回归分析显示原发肿瘤位置、TNM分期、ALP水平是结肠癌骨转移的独立危险因素。结论:左、右半结肠癌在病理特点、临床表现、生物学行为、生存预后等方面存在差异，本文为区分左、右半结肠癌骨转移的不同病理特征及预后评价提供了依据。     

1p31.1 microdeletion including only NEGR1 gene in two patients

Neuronal growth regulator 1 (NEGR1), a member of the immunoglobulin superfamily cell adhesion molecule subgroup IgLON, has been involved in neuronal growth and connectivity. Genetic variants, in or near the NEGR1 locus, have been associated with obesity and, more recently, with learning difficulties, intellectual disability, and psychiatric disorders.Here, we described the only second report of NEGR1 gene disruption in 1p31.1 microdeletion in two patients. Patient 1 is a 14-year-old female with neurological and psychiatric features present also in her family. Patient 2 is a 5-month-old infant showing global hypotonia as unique neurological features till now. This patient also carries 7p22.1 duplication, of paternal origin, that could be responsible for some malformations present in the child.We hypothesize a role of NEGR1 in producing the phenotype of our patients and compare them with other cases previously reported in the literature and DECIPHER database to better identify a possible genotype-phenotype correlation.
