Emergency Care EMTALA Alterations During the COVID-19 Pandemic in the United States

The coronavirus 2019 pandemic has affected almost every aspect of health care delivery in the United States, and the emergency medicine system has been hit particularly hard while dealing with this public health crisis. In an unprecedented time in our history, medical systems and clinicians have been asked to be creative, flexible, and innovative, all while continuing to uphold the important standards in the US health care system. To continue providing quality services to patients during this extraordinary time, care providers, organizations, administrators, and insurers have needed to alter longstanding models and procedures to respond to the dynamics of a pandemic. The Emergency Medicine Treatment and Active Labor Act of 1986, or EMTALA, is 1 example of where these alterations have allowed health care facilities and clinicians to continue their work of caring for patients while protecting both the patients and the clinicians themselves from infectious exposures at the same time.     

Emerging therapeutic options in inflammatory bowel disease

Inflammatory bowel disease (IBD) is a chronic disease that requires chronic treatment throughout the evolution of the disease, with a complex physiopathology that entails great challenges for the development of new and specific treatments for ulcerative colitis and Crohn´s disease. The anti-tumor necrosis factor alpha therapy has impacted the clinical course of IBD in those patients who do not respond to conventional treatment, so there is a need to develop new therapies and markers of treatment response. Various pathways involved in the development of the disease are known and the new therapies have focused on blocking the inflammatory process at the gastrointestinal level by oral, intravenous, subcutaneous, and topical route. All these new therapies can lead to more personalized treatments with higher success rates and fewer relapses. These treatments have not only focused on clinical remission, but also on achieving macroscopic changes at the endoscopic level and microscopic changes by achieving mucosal healing. These treatments are mainly based on modifying signaling pathways, by blocking receptors or ligands, reducing cell migration and maintaining the integrity of the epithelial barrier. Therefore, this review presents the efficacy and safety of the new treatments that are currently under study and the advances that have been made in this area in recent years.     

基于网络药理学和临床试验探讨前列消汤对ⅢA型前列腺炎IL-17与Foxp3表达影响研究＊

目的 基于网络药理学进行前列消汤治疗慢性前列腺炎的预测，同时采用临床试验进行验证，证明前列消汤对ⅢA型前列腺炎患者的临床疗效及对前列腺液（Expressed Prostatic Secretion， EPS）中白细胞介素17（interleukin 17， IL-17）及双头叉转录因子p3（Forkhead box p3， Foxp3）表达的影响。方法 采用网络信息学分析方法，筛选出前列消汤在ⅢA型前列腺炎治疗中发挥疗效的主要作用靶点，采用临床随机非盲法，将符合纳入标准的80例ⅢA型前列腺炎湿热下注证患者随机分为观察组和对照组各40例，观察组口服自拟前列消汤，对照组口服银花泌炎灵片。观察治疗前后两组的症状及证候评分情况、前列腺按摩液以及其IL17、Foxp3表达的差异。取40例正常男性前列腺液为正常对照。结果 网络药理学分析结果提示IL17信号通路为前列消汤治疗慢性前列腺炎的重要通路之一，临床试验结果提示经治疗后观察组有效率达89.19%，较对照组的73.68%为优（P < 0.05）。两组患者服药后的临床表现、前列腺按摩液WBC、症状及证候评分均存在明显改善。观察组和对照组IL-17水平较治疗前下降，Foxp3表达较治疗前升高（P < 0.05）。观察组对降低IL-17表达和提升Foxp3表达上较对照组差异更大（P < 0.05）。观察组治疗后与正常组IL-17和Foxp3水平比较差异较小（P > 0.05）。结论 网络药理学能一定程度上预测中药作用于疾病的相应靶点，前列消汤对ⅢA型前列腺炎湿热下注证患者的临床症状有明显改善作用，并能降低IL-17表达，对Foxp3表达有提升作用，在总有效率和对细胞因子的影响上较银花泌炎灵片组明显。     

Effect and Safety of Tongyan Spray (通咽喷雾剂) on Hyoid Motion in Patients with Dysphagia after Ischemic Stroke

Objective: To observe the effects and safety of Tongyan Spray (通咽喷雾剂) on the range and time of hyoid motion in patients with ischemic post-stroke dysphagia. Methods: Seventy-two patients with ischemic post-stroke dysphagia were selected and randomly assigned to a treatment group (36 cases) and a control group (36 cases) by a random number table from January 2013 to October 2014. All patients swallowed 4 kinds of barium meals with different traits respectively, and each patient underwent video fluoroscopy (VF) examination twice. In the treatment group, Tongyan Spray was sprayed to the pharynx on both sides and the middle part once respectively. The spray was applied 30 min before the second examination. Purified water at room temperature was used as placebo in the control group. The changes in the range and time of hyoid motion in both groups were observed before and after treatment. Results: Six patients dropped out in each group, and 60 patients completed the study and were included in the final analysis. Significant improvement was observed in the range of superior hyoid excursion distance and the time of hyoid motion in the treatment group compared with the control group (P<0.05). There were no obvious adverse reactions observed in oral mucosa in both groups during the whole study. Conclusion: Tongyan Spray was an effective and safe medicine for improving swallowing function in patients with ischemic post-stroke dysphagia.     

人工智能在中医药领域的应用进展及现状思考

人工智能（Artificial Intelligence，AI）的蓬勃兴起为现代社会带来了前所未有的机遇，中医药是中华民族传承千年的文化瑰宝。随着人工智能技术不断在中医药领域的科技创新中崭露头角，二者的融合不断加深，人工智能在中医药领域的发展前景、争议挑战也引发了诸多思考。本文将从人工智能在中医药领域的应用入手，对人工智能辅助中医诊断、智能决策与数据挖掘、健康管理及中草药现代化研究等方面，就近年来国内外研究进展进行总结与分析，以期为AI视域下实现中医药现代化、智能化赋能。     

基于内容分析法的中医类APP现状分析

随着手机APP对人们日常工作和生活方式的改变，中医类APP日益得到关注。文章基于内容分析法对目前中医类APP现状进行梳理，分析存在的问题，对未来中医类APP的设计和开发提出建议。以每一个APP为分析单元，从一般情况、主要功能、用户评价等3个方面进行分析，建立了7个维度22个细目的编码体系，进行频数统计和分析。发现目前中医类APP功能丰富，用户广泛，成为中医药服务及中医科学传播的重要载体，具有良好的用户粘度及巨大市场需求，但存在质量良莠不齐、内容资源不佳等问题。提出中医类APP开发应符合中医药发展战略的方向，应进一步规范中医类APP隐私政策和相关法律法规；并探索中医类APP的评价标准和评价指标体系，促进和规范中医类APP的质量提升和不断发展。     

基于外邪理论探讨肿瘤的发病机制

肿瘤防控是当今世界性一大难题，目前我国每年新发肿瘤病例即将突破400万。近年来，我国肿瘤总体发病率和死亡率呈现逐年上升趋势，肿瘤的高死亡率和低治愈率已严重威胁我国居民健康，很大程度影响了患者的生存质量，大大降低患者的生活水平，危害患者的身心健康。中医认为，肿瘤发病的病因复杂，病机变化多端，是内外因相互影响、相互作用的结果。若在外邪作用于人体之初，及时辨证施治，防止伏邪入里发生传变，将大大减少肿瘤疾病的发生和发展。因此，外邪理论与肿瘤的发病机制亟待进一步探究。在中国知网（CNKI），Public Medline（PubMed）数据库中以外感、邪气、中医、肿瘤、发病机制等关键词进行检索，本文共纳入67篇中英文文献为参考，对外邪理论与肿瘤发病机制进行全面探讨。强调了外邪在肿瘤发病中的重要作用，以及中医药在早期防治肿瘤中具有显著的优势。外邪如风邪、寒邪、湿邪、火邪、从口鼻皮表而入的邪气等因素，使得肿瘤的发生更具复杂性。中医药可以在肿瘤发展早期进行有效的防护和干预，可大大提高防病抗肿瘤的目的，减少肿瘤的发生、发展、传变，使临床用药更有效、更精准、更具靶向性，不至使肿瘤的治疗错失良机，为临床治疗肿瘤提供更明确的指导方向。
