Large cystic infiltrating ductal carcinoma in male breast

Cystic infiltrating ductal carcinoma is a very rare entity that, to the best of our knowledge, has not yet been reported in males. We report the sonographic and CT findings of a large cystic infiltrating ductal carcinoma in a 51-year-old man.

Interactions between sleep disorders and oral diseases

Dental sleep medicine is a rapidly growing field that is in close and direct interaction with sleep medicine and comprises many aspects of human health. As a result, dentists who encounter sleep health and sleep disorders may work with clinicians from many other disciplines and specialties. The main sleep and oral health issues that are covered in this review are obstructive sleep apnea, chronic mouth breathing, sleep‐related gastroesophageal reflux, and sleep bruxism. In addition, edentulism and its impact on sleep disorders are discussed. Improving sleep quality and sleep characteristics, oral health, and oral function involves both pathophysiology and disease management. The multiple interactions between oral health and sleep underscore the need for an interdisciplinary clinical team to manage oral health‐related sleep disorders that are commonly seen in dental practice.     

Anaphylaxis after prick‐to‐prick test with fish

Skin prick testing is the diagnostic procedure for allergies and is considered to be safe. It is usually performed using the prick and the prick‐to‐prick method. Herein is described a pediatric case of anaphylaxis during prick‐to‐prick testing with raw fish in a patient who had consumed fish without any systemic allergic reactions beforehand, to illustrate that skin prick testing should be carefully planned and performed with caution in order to avoid potentially serious risks for the patient.     

半边旗提取物5F-Na盐溶液的制备及体外抑癌作用研究

目的:制备5F-Na盐,并观察其对肺癌细胞株NCL-H460和肝癌细胞株BEL-7402的杀伤作用。方法:加入0.5mol·L-1NaOH使半边旗提取物5F完全溶解,稀HCl调节pH值为7.4,加入磷酸盐缓冲液使其pH值稳定,高效液相色谱法测定5F-Na盐溶液中5F的含量。通过MTT法检测所制备5F-Na盐溶液对肺癌细胞株NCL-H460和肝癌细胞株BEL-7402的杀伤作用。结果:所制备5F-Na盐溶液中5F为标示量的(100.51±2.18)%,其对NCl-H460细胞株24、48、72h的IC50分别为23.7、14.2、7.0μg·mL-1,对BEL-7402细胞株24、48、72h的IC50分别为157.3、41.5、21.0μg·mL-1。结论:本研究制备的5F-Na盐溶液能有效抑制癌细胞株生长增殖。
