〔記者歐素美/台中報導〕 一名50歲男子日前與家人中秋烤肉時吃下一整尾鯖魚,不到1小時突然出現臉部及上半身潮紅、頭痛、心悸、皮膚紅疹等症狀,家人原以為只是喝啤酒後酒精造成臉紅,沒想到症狀持續加劇,趕緊送往衛生福利部豐原醫院急診,結果竟因鯖魚保存不當,形成大量組織胺,就算烤熟也沒用,一樣導致「組織胺中毒」,經服用藥物治療才改善。
衛生福利部豐原醫院急診室主任王者仁表示,鯖魚、鮪魚、鰹魚等魚類含有較高量的組胺酸,若捕撈、運送或料理前沒有妥善低溫保存,魚肉中的細菌可能將組胺酸轉換成大量組織胺,食用後常在短時間內出現臉紅、頭痛、心悸、紅疹、搔癢、噁心、腹痛或腹瀉等症狀,外觀看起來很像一般食物過敏。

王者仁指出,組織胺中毒並不等同於對魚過敏,而是吃進魚肉中已經形成的大量組織胺;若同桌多人吃了相同魚貨後陸續出現類似症狀,也要提高警覺。
王者仁說,民眾常疑問「魚已經烤熟,為什麼還會出問題」?其實,關鍵在於魚肉在保存不當的過程中已經形成大量組織胺,後續即使經過烘烤或煮熟,也無法有效去除,因此「魚有烤熟」不能取代料理前的妥善冷藏。此外,部分組織胺含量升高的魚肉,外觀或氣味未必出現明顯異常,也不能單靠聞味道或看顏色判斷是否安全。
王者仁指出,組織胺中毒通常發作較快,民眾若吃完魚後短時間內突然出現臉紅、心悸、頭痛、搔癢或紅疹,不要只當成喝酒臉紅或一般海鮮過敏,若伴隨呼吸不適、胸悶、血壓下降等情形,應儘速就醫,並主動告知醫師食用的魚類及發作時間,另外預防方面,重點仍在魚貨從取得到料理前持續做好低溫保存,降低組織胺形成的風險。

Li Hongna, an attending psychiatrist at Beijing Children's Hospital, pointed out that children experiencing dizziness, abdominal pain and other discomforts without organic causes may be somatic manifestations of anxiety, stress and other emotions, especially during the school season, before exams or when families are tense. It is recommended that parents help their children alleviate symptoms through acceptance, emotional naming and joint problem-solving.

Zhang Zhiyuan, director of the Reproductive Medicine Center of Taipei Tzu Chi Hospital, pointed out that the success rate of egg freezing is affected by age, ovarian inventory (such as AMH value) and the reason for freezing the eggs. It is not just the younger the better. He stressed that excessive anxiety should be avoided, and used a case to illustrate a successful birth after freezing eggs at the age of 41.

Nutritionist Xu Cijia pointed out that asking elders to name more than 12 kinds of four-legged animals in one minute is a passing standard for cognitive function. However, failure to meet the standard does not mean dementia. He emphasized that there are four warning signs such as repeated forgetting, cooking mistakes, getting lost easily, and deterioration of judgment, which require medical treatment. He also provided five major brain protection principles to reduce the risk of dementia.

Professor Li Qiubai's team from the Department of Rheumatology and Immunology at Wuhan Union Medical College Hospital verified the feasibility of the CD3×CD19 T cell adapter in the treatment of systemic lupus erythematosus through a phase I clinical trial. All 10 patients met the SRI-4 clinical response standard, and some achieved drug-free remission, opening up a new path for the treatment of autoimmune diseases.

Nutritionist Xie Yifang pointed out that taro is a whole-grain staple food, rich in dietary fiber and resistant starch, but it can still raise blood sugar. It is recommended to steam and stew instead of frying, pair it with protein and vegetables, and reduce other staple foods appropriately. She also reminds people with diabetes, weight loss, and high triglycerides to control their total carbohydrate intake. She also emphasizes that taro must be fully cooked to avoid stimulation of calcium oxalate crystals.

Tainan Christian Tainan Xinlou Hospital, which has a history of 161 years, was established in the Madou area with poor medical resources 30 years ago and has long-term dispatched staff to the rural areas of Jiangjun District for medical treatment.
