Primary cardiac tumors, which originate from the heart, are uncommon and can be classified as benign or malignant, with the majority being benign. Malignant primary cardiac tumors have a poor prognosis. Benign ones may also cause severe hemodynamic and electrophysiological consequences, but the prognosis is generally good if they are detected early and treated properly. In recent years, researches on the genetic and molecular causes of primary cardiac tumors have yielded some promising breakthroughs, with some of them already being translated into clinical practice. This article reviews research progress and its use in precise diagnosis and targeted therapy from the perspective of DNA, RNA, and protein changes, as well as prospects the promising research directions in the future.
目的:探讨儿童糖尿病患者的营养治疗方法以提高治疗效果。 方法:随机选择20例胰岛素依赖型儿童糖尿病患者,结合年龄、体重、病情、胰岛素用量、营养状况、生长发育需要设计个体化营养治疗方案。结果:通过营养治疗,除1例患儿家属在病情控制相对稳定,但血糖未有效控制提前出院外,其余19例患者均坚持营养治疗。治疗前后,随机血糖、餐后2 h血糖差异有统计学意义,P＜0.05;糖化血红蛋白差异无统计学意义。结论:个体化的营养治疗有助于儿童糖尿病患者血糖控制,并能促进儿童的生长发育及提高生活质量。
ObjectiveTo investigate a more convenient and safe sampling method for viral nucleic acid detection of coronavirus disease 2019.MethodsAn oropharyngeal swab and nasopharyngeal swab were simultaneously taken from 100 patients with coronavirus disease 2019 in a hospital in Wuhan. Then the efficacies of two sampling methods were compared on the positive rates of viral nucleic acid detection.ResultsThe positive rate for SARS-CoV-2 was 54% in oropharyngeal swabs, while 89% positive in nasopharyngeal swabs. There was a significant difference in the detection rate between oropharyngeal swab and nasopharyngeal swab (χ2=3.850 4, P=0.049 7).ConclusionsThe positive rate for nucleic acid testing from nasopharyngeal swabs are significantly better than that from oropharyngeal swabs. Therefore, sampling by nasopharyngeal swabs, rather than oropharyngeal swabs, should be chosen as the preferred virological screening method for patients with coronavirus disease 2019.
