Comparison of the practicability of ultrasound and spiral computed tomography in the diagnosis of colon cancer: A protocol for systematic review and meta-analysis

Background:Colon cancer is a common malignant tumor of the gastrointestinal tract. Therefore, a clear diagnosis is particularly important for the treatment of colon cancer. Ultrasound and spiral computed tomography (CT) can both be used in the diagnosis, but each has its own advantages and disadvantages, which could cause confusion in clinical choice. The purpose of this study was to systematically evaluate the practicability of spiral CT and ultrasound in the diagnosis of colon cancer.Methods:A systematic search was performed by retrieving on English databases (PubMed, Embase, Web of Science, the Cochrane Library) and Chinese databases (CNKI, Wanfang, Weipu [VIP], CBM). Besides, manually search for Google and Baidu academic of diagnostic experimental study of ultrasound and spiral CT in the diagnosis of Colon Cancer. The retrieval time limit was from the establishment of the database to October 2020. Two researchers independently extracted and evaluated the quality of the data in the included study. A meta-analysis was performed using Meta Disc1.4 and RevMan5.3 software.Results:Sensitivity, specificity, positive Likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were used to determine the diagnostic efficacy of ultrasonography and helical CT in colorectal cancer.Conclusions:This study will compare the practicability of CT and ultrasound in the diagnosis of colon cancer and provide reliable evidence-based basis for clinicians to choose the appropriate or best evidence-based basis.Ethics and dissemination:The private information from individuals will not be published. This systematic review also will not involve endangering participant rights. Ethical approval is not required. The results may be published in a peer-reviewed journal or disseminated in relevant conferences.OSF Registration number:DOI 10.17605/OSF.IO/WAJHQ     

金水宝片联合依诺肝素对维持性血液透析患者血脂代谢的影响

目的：探究金水宝片联合依诺肝素对维持性血液透析患者血脂代谢的影响。方法：选取2018年12月至2019年3月马鞍山十七冶医院血液净化中心进行透析的患者154例作为研究对象，根据用药不同分为对照组和观察组,每组77例。对照组常规应用依诺肝素抗凝，观察组在对照组抗凝基础上加用金水宝片，各组均干预3个月，比较2组患者血脂变化及持续血液透析并发症发生情况。结果：治疗后，观察组患者三酰甘油、总胆固醇及低密度脂蛋白胆固醇水平下降，高密度脂蛋白胆固醇升高，与治疗前比较差异均有统计学意义（P<0.05），与对照组治疗后比较，差异有统计学意义（P<0.05）；观察组总并发症发生率明显低于对照组，2组比较差异有统计学意义（P<0.05）；2组患者维持性血液透析不良反应发生率均较低，组间比较差异无统计学意义（P>0.05）。结论：金水宝片联合依诺肝素有助于改善维持性血液透析患者血脂代谢水平，降低维持性血液透析相关并发症，值得临床推广应用。     

胞宫胞脉胞络理论与子宫内膜容受性关系探析

胞宫胞脉胞络理论是中医基于脏腑理论对女子生殖功能的基本认识.子宫体、宫颈、卵巢、输卵管、盆壁及其相关的血管、神经、韧带及受体当属胞宫、胞脉、胞络功能范畴.胞脉和胞络属于胞官的一部分.胞脉、胞络将脏腑化生之气血全面布散于胞官,心、肾通过胞脉、胞络与胞官相联系."精满" "血足"是良好子宫内膜环境的体现.肾气亏损,胞脉失疏,冲任不充,胞官瘀滞,藏泻失序,表现为子宫内膜较薄及血供不足,不利于孕卵的着床.治疗子宫内膜容受性低下应予补肾气,通胞脉,自拟二补助育汤,可以改善子宫内膜血液循环,增加子宫内膜厚度,提高辅助妊娠成功率.

Dexamethasone treatment attenuates early seawater instillation-induced acute lung injury in rabbits.

There is very little evidence on the value of giving corticoids in cases of seawater drowning induced acute lung injury/acute respiratory distress syndrome (ALI/ARDS). Therefore, this study aimed to investigate whether dexamethasone treatment can attenuate seawater instillation-induced acute lung injury in rabbits. Seawater (4 ml/kg body weight) was instilled into the lower trachea of ventilated, anesthetized rabbits. Then these rabbits were assigned randomly 20 min later to receive intravenous injection of 1mg/kg body weight of dexamethasone (dissolving in 2 ml of normal saline) or 2 ml of normal saline. All animals demonstrated immediate drops in arterial oxygen tension (PaO2) and the total thoracic compliance, which were significantly improved after 2 h of dexamethasone treatment. Histopathological study also indicated that dexamethasone treatment markedly attenuated lung histopathological changes, alveolar hemorrhage and inflammatory cells infiltration with evidence of decreasing of myeloperoxidase (MPO) activity and tumor necrosis factor-alpha (TNF-alpha) concentration in lung tissue. In addition, dexamethasone treatment reduced extravascular lung water and lung epithelial-endothelial barrier permeability, up-regulated the expression of surfactant protein-A (SP-A) and alpha-epithelial Na+ channel, and increased Na+/K+-adenosine triphosphatase (Na+/K+-ATPase) activity and Na+/K+-ATPase-alpha1 protein abundance. Thus, these data indicate that dexamethasone treatment might be of benefit in patients with seawater aspiration-induced ALI.
