A bag of chocolate milk tea like plasma was displaced from the body of a patient with severe hypertriglyceridemia, which is shocking. Recently, the 12th People's Hospital of Guangzhou City conducted two rounds of dual plasma exchange therapy for Mr. Chen. On January 16th, the results of the re examination showed that his triglyceride levels had returned to normal range from 50 times higher than the previous limit, greatly reducing the risk of fatal diseases. On January 11th, Mr. Chen, a 49 year old patient, came to the endocrinology department of the 12th Hospital of the city with a medical examination report. He thought it was a trivial matter and was immediately admitted to the hospital. The physical examination report from the external hospital shows that Mr. Chen's triglycerides are as high as 87.54mmol/L, which is 50 times the normal value. He belongs to extremely severe hypertriglyceridemia, which is relatively rare in clinical practice and can easily trigger life-threatening diseases such as acute pancreatitis, myocardial infarction, cerebral infarction, pulmonary embolism, etc. After admission, the endocrinology department will review the patient's blood lipids and complete relevant examinations to rule out acute pancreatitis, myocardial infarction, coagulation abnormalities, etc. At the same time, hydration and oral lipid-lowering drugs will be given for treatment. Based on the examination results, Li Wanmei, Deputy Director of the Internal Medicine Department and Chief Physician of the Endocrinology Department of the 12th Hospital of the city, and Chen Yunchao, Deputy Director and Chief Physician of the Poisoning Treatment Center, jointly consulted and formulated a dual plasma exchange (DFPP) plan. The whole bag of "chocolate milk tea" like plasma that was replaced from the body for the first time was shocking. Mr. Chen received two plasma exchange treatments, and his triglyceride levels finally significantly decreased. On January 16th, the recheck value dropped to 11.04 mmol/L. The four indicators in the physical examination report indicate that in recent years, with the improvement of living standards and the change of eating habits, the incidence rate of hyperlipidemia has also increased year by year. The 2020 Report on the Nutrition and Chronic Disease Status of Chinese Residents shows that the prevalence of hyperlipidemia among residents aged 18 and above in China is as high as 35.6%. Hyperlipidemia has no obvious symptoms, "silently" erodes the patient's blood vessels, liver, pancreas, etc., leading to a sudden rise in the risk of atherosclerosis, pancreatitis and other diseases, often known as the "invisible killer". There are many factors that can induce hyperlipidemia. "This patient sits quietly for a long time due to work reasons and likes to eat nuts." Li Wanmei said that in daily life, in addition to high cholesterol foods such as peanuts, fatty meat, and fried foods, bad habits such as alcohol abuse and smoking are also very likely to cause elevated blood lipids. What numerical abnormalities in the medical examination report should be alert to blood lipid abnormalities? In clinical practice, the presence of lipid abnormalities is mainly determined based on four values: total cholesterol, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. If total cholesterol ≥ 5.7mmol/L, triglycerides ≥ 1.7mmol/L, low-density lipoprotein cholesterol ≥ 3.4mmol/L, and high-density lipoprotein cholesterol ≤ 1mmol/L meet one of the criteria, it can be diagnosed as dyslipidemia. Two daily adjustments are beneficial for lowering blood lipids. The triglyceride value is relatively high, such as between 1.7-5.7mmol/L
