ObjectiveTo investigate the correlation between tumor-vessel signs on 64-slice spiral CT (MSCT) and malignant change of tubulovillous adenoma in the colon and rectum. MethodsA retrospective study of the image and the clinical data of 16 patients with tubulovillous adenoma or malignant change proved by pathologies from February 2010 to October 2012 was conducted. The tumor-vessel signs were analyzed by multiplanar reformation (MPR) and maximum intensity projection (MIP) on picture archiving and communication systems workstation. ResultsAmong the 16 cases of tubulovillous adenoma or malignant change, 2 cases of tumor diameter≤2 cm had no tumor-vessel sign; and in the 14 cases of tumor diameter >2 cm, 13 were observed to bear tumor-vessel signs. The size of the tumor and tumor-vessel signs showed a certain correlation (r=0.618, P=0.002). And the manifestation of tumor-vessel signs had obvious differences between benign and malignant tumor. For the adenoma group, it showed venous blood vessel involvement, and downy and natural contour; for the adenocarcinoma group, it showed arterial blood vessel involvement, blood vessels with uneven thickness, visible expansion and irregular defect manifestations. No obvious difference was detected among tumor-vessel signs of adenocarcinoma with different malignant degree. ConclusionMSCT combined with image reconstruction techniques (such as MPR and MIP) can clearly demonstrate tumor blood supply, and tumor-vessel in the arterial phase may suggest a high risk of malignant change of tubulovillous adenoma in the colon and rectum.
目的 探讨经胼胝体-穹窿间入路切除第三脑室肿瘤术后，近期下丘脑反应的发生情况及相关因素，为防治第三脑室肿瘤术后下丘脑反应提供参考。 方法 回顾分析2003年1月－2008年12月经胼胝体-穹窿间入路切除的78例第三脑室肿瘤患者手术后近期（1个月内）下丘脑反应的发生情况，并将其按照肿瘤部位、病理性质、大小、血供、手术切除程度进行分类统计，用SPSS 13.0软件logistic 回归分析影响这些并发症的因素。 结果 78例术后下丘脑反应37例，发生率47.4%；死亡5例，下丘脑反应病死率为13.5%（5/37）。其中电解质糖代谢紊乱33例（42.3%），尿崩症27例（34.6%），激素水平低下16例（20.5%），高热6例（7.7%）。好转痊愈率：激素水平低下43.7%，其余均＞70%。第三脑室前部颅咽管瘤术后最容易发生下丘脑反应（P＜0.05）。 结论 经胼胝体-穹窿间入路切除第三脑室肿瘤术后近期存在程度不同的下丘脑反应，其发生与肿瘤部位、病理性质有密切关系。经积极治疗，大部分下丘脑反应能在术后1个月内好转甚至痊愈。
Recently, real world studies (RWS) have received increasing attentions. Such studies typically involve patient information, and their results may have potentially significant impact on patient well-being and safety. When reviewing the protocol of real world studies, ethical issues should be carefully considered and assessed. This paper discussed three issues, including the overview of bioethics and its application to classic clinical trials, key features of RWS, and medical ethical considerations on RWS.
ObjectiveTo explore and analyze the risk factors of pleural invasion in patients with small nodular type stage ⅠA pulmonary adenocarcinoma.MethodsFrom June 2016 to December 2017, 168 patients with small nodular type stage ⅠA pulmonary adenocarcinoma underwent surgical resection in the First Affiliated Hospital of Nanjing Medical University. There were 59 males and 109 females aged 58.7±11.5 years ranging from 28 to 83 years. The clinical data were analyzed retrospectively. Single factor Chi-square test and multivariate logistic regression were used to analyze the independent risk factors of pleural invasion.ResultsAmong 168 patients, 20 (11.9%) were pathologically confirmed with pleural invasion and 148 (88.1%) with no pleural invasion. Single factor analysis revealed significant differences (P<0.05) in nodule size, nodule status, pathological type, relation of lesion to pleura (RLP), distance of lesion to pleura (DLP), epidermal growth factor receptor (EGFR) mutation between patients with and without pleural invasion in stage ⅠA pulmonary adenocarcinoma. Logistic multivariate regression analysis showed that significant differences of nodule size, nodule status, RLP, DLP and EGFR mutation existed between the two groups (P<0.05), which were independent risk factors for pleural invasion.ConclusionImageological-pathological-biological characteristics of patients with small nodular type stage ⅠA pulmonary adenocarcinoma are closely related to pleural invasion. The possibility of pleural invasion should be evaluated by combining these parameters in clinical diagnosis and treatment.
Differential diagnosis of benign and malignant ground glass nodule (GGN) is of great significance to the early detection, diagnosis and treatment of lung cancer. Increasing attention has been paid to radiomics technology application in early diagnosis of benign and malignant GGN, which can analyze the characteristic appearances of GGN in non-invasive manner. This article reviews the latest research progress of radiomics in the diagnosis of GGN.
Postoperative gastrointestinal disorder (POGD) is a common complication after surgery under anesthesia. Strategies in combination with traditional Chinese medicine and Western medicine have shown some distinct effects but standardized clinical practice guidelines are not available. Thus, a multidisciplinary expert team from various professional bodies including the Perioperative and Anesthesia Professional Committees of the Chinese Association of Integrative Medicine (CAIM), jointly with Gansu Province Clinical Research Center of Integrative Anesthesiology/Anesthesia and Pain Medical Center of Gansu Provincial Hospital of Traditional Chinese Medicine and WHO Collaborating Center for Guideline Implementation and Knowledge Translation/Chinese Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Center /Gansu Provincial Center for Medical Guideline Industry Technology/Evidence-based Medicine Center of Lanzhou University was established to develop evidence-based guidelines. Clinical questions (7 background and 12 clinical questions) were identified through literature reviews and expert consensus meetings. Based on systematic reviews/meta-analyses, evidence quality was analyzed and the advantages and disadvantages of interventional measures were weighed with input from patients’ preferences. Finally, 20 recommendations were developed through the Delphi-based consensus meetings. These recommendations include disease definitions, etiologies, pathogenesis, syndrome differentiation, diagnosis, and perioperative prevention and treatment.
