Malignant tumors are one of the leading causes of death which impose an increasingly heavy burden on all countries. Therefore, the establishment of research models that closely resemble original tumor characteristics is crucial to further understanding the mechanisms of malignant tumor development, developing safer and more effective drugs, and formulating personalized treatment plans. Recently, organoids have been widely used in tumor research owing to their advantages including preserving the structure, heterogeneity, and cellular functions of the original tumor, together with the ease of manipulation. This review describes the history and characteristics of tumor organoids and the synergistic combination of three-dimensional (3D) culture approaches for tumor organoids with emerging technologies, including tissue-engineered cell scaffolds, microfluidic devices, 3D bioprinting, rotating wall vessels, and clustered regularly interspaced short palindromic repeats-CRISPR-associated protein 9 (CRISPR-Cas9). Additionally, the progress in research and the applications in basic and clinical research of tumor organoid models are summarized. This includes studies of the mechanism of tumor development, drug development and screening, precision medicine, immunotherapy, and simulation of the tumor microenvironment. Finally, the existing shortcomings of tumor organoids and possible future directions are discussed.  相似文献

AIM:To evaluate the association between HLA-DRB1 alleles and Han and Uyghur ulcerative colitis (UC) patients residing in the Xinjiang Uyghur Autonomous Region of China. METHODS:In this study, 102 UC patients (53 Han including 22 men and 31 women, and 49 Uyghur patients including 25 men and 24 women; aged 48.07 ± 15.83 years) and 310 age- and sex-matched healthy controls were enrolled in the Department of Gastroenterology, Xinjiang People’s Hospital of China from January 2010 to May 2011. UC was diagnosed based on the clinical, endoscopic and histological findings following Lennard-Jones criteria. Blood samples were collected and genomic DNA was extracted by routine laboratory methods, and both polymerase chain reaction and gene sequencing were used to identify HLA-DRB1 allele variants. The potential association between genetic varia-tion and UC in Han and Uyghur patients was examined. There were no statistical differences in HLA-DRB1 allele frequencies in Han UC patients. RESULTS:There was no significant difference in the sex ratio between the controls and UC patients (P = 0.740). In Han patients with UC (n = 53), HLA-DRB1 *03 , *13 allele frequencies were lower than in healthy controls (n = 161), but not statistically significant, and HLA-DRB1*04*11*14 allele frequencies were higher than in healthy controls, but without statistical significance. Differences between Uyghur UC patients and the control group were observed for HLA-DRB1*04 and HLA-DRB1*13 , both showed a greater frequency in UC patients (10.21% vs 2.69%, P = 0.043; 14.29% vs 4.03%, P = 0.019). HLA-DRB1*14 also showed a greater frequency in UC patients (14.29% vs 2.69%, P = 0.006). The frequencies of DRB1*04 , *13*14 alleles were increased in Uyghur UC patients compared with normal controls. The frequency of DRB1 * 08 was decreased in Uyghur UC patients compared with normal controls. HLA-DRB1 alleles showed no association with UC in Han patients. There were no statistical differences in HLA-DRB1 allele frequencies in Han UC patients. The frequenci  相似文献

中医药调治亚健康失眠概况   总被引:4,自引:4,他引:0  
亚健康状态普遍存在,是当今社会威胁人类健康的隐形杀手,调查表明75%的人处于亚健康状态,而失眠又占其中的42.5%。西医针对亚健康失眠多使用镇静催眠药物,甚则运用抗精神类药物达到睡眠的生理要求,此类药物会引起日间困倦和认知功能的损害,并会产生耐药性和依赖性。祖国医学对亚健康的认识结合了\"治未病\"的观点,强调未病先防,既病防传的理论。中医药治疗亚健康失眠的优势在于可根据中医辩证分型,采用不同方药论治,针对性强,因而取得了较为满意的疗效;且治疗手段多样,包括针灸、耳穴、心理干预、气功等。适当的联合运用或可获得可喜的疗效。用中医养生保健理念纠正不良睡眠习惯,保持健康的生活方式对预防亚健康失眠起到重要作用。应加强多中心大样本的临床研究,以加深对亚健康失眠的证候分布及辩证规律的认识,从而进一步丰富和完善中医学对亚健康失眠的诊治理论和治疗手段。  相似文献

目的:测定新生血管性青光眼(neovascular glaucoma,NVG)患者血清及房水中IL-6、IL-8、TNF-α的表达水平,并探讨IL-6、IL-8、TNF-α在NVG发生发展中的意义。

方法:采用前瞻性病例分析方法,纳入2015-08/2017-03在我院诊治的NVG患者38例38眼,并按虹膜新生血管分级标准分为Ⅱ级8眼,Ⅲ级19眼,Ⅳ级11眼。选取同期原发性开角型青光眼(primary open-angle glaucoma,POAG)患者31例31眼、年龄相关性白内障患者33例33眼作为对照。分别于术前检测患者眼压水平,分别抽取患者静脉血及房水样本,利用酶联免疫吸附法(ELISA)检测血清及房水中IL-6、IL-8、TNF-α含量。

结果:NVG组血清和房水中IL-6、IL-8、TNF-α水平均明显高于POAG组和白内障组,差异有统计学意义(P<0.05); POAG组血清和房水中IL-6、IL-8、TNF-α水平显著高于白内障组(P<0.05)。Ⅳ级NVG组血清和房水中IL-6、IL-8、TNF-α水平显著高于Ⅲ级患者,差异有统计学意义(P<0.05),Ⅲ级患者血清及房水中IL-6、IL-8、TNF-α水平明显高于Ⅱ级,差异有统计学意义(P<0.05)。NVG患者血清及房水中IL-6、IL-8、TNF-α水平均与眼压水平呈正相关(P<0.05)。

结论:IL-6、IL-8、TNF-α在NVG患者血清及房水中高表达,可能参与虹膜新生血管生长和眼压升高。  相似文献
