Yousiling —— protamine recombinant human insulin mixed injection (30/70) This insulin is a pre-mixed insulin, and one insulin contains 30% recombinant human insulin and 70% protamine recombinant human insulin, which is simply 30% short-acting insulin and 70% medium-acting insulin. Briefly speaking, the types of insulin can be divided into four categories according to the time-effect of action: quick-acting insulin: Youbile, Novorosharp, Abed short-acting insulin: Novorozil R, Youbilin R, Ganshulin R, Zhonghelin R medium-acting insulin: Novorozil N, Youbilin N, Ganshulin N, Chonghelin N long-acting insulin: Laideshi, Changxiulin, Novoropeace, Novorozil. Manufacturers also produce premixed insulin (short-acting and medium-acting) and premixed insulin analogues (quick-acting and medium-acting) in proportion, and make up for the lack of insulin secretion by injecting 2-3 times a day. Many sugar friends can&;t understand the complicated names of insulin, and don&;t know what their respective characteristics are. They can only distinguish the advantages and disadvantages of insulin by price, and make a simple comparison for everyone through the following figure. The premixed insulin used in the subject is to mix short-acting insulin and medium-acting insulin together in advance, and the two kinds of insulin with aging effect are injected at the same time, but because of the different peak and duration of action, the short-acting insulin is mainly used to reduce postprandial blood sugar, while the medium-acting insulin reduces fasting blood sugar and non-postprandial blood sugar. Cheap is the advantage of Yousiling, but it also has its shortcomings in sugar control. Compared with other premixed insulin analogues, such as Novozil 30 and Youbile 25, the quick-acting insulin has shorter onset time (15 minutes), faster peak time (1 hour), more convenient injection (about 15 minutes before meals) and easier coincidence with the rising curve of postprandial blood sugar (lasting for 4-6 hours), so it can control postprandial blood sugar. If the subject&;s condition is not serious, and his remaining islet function is acceptable, especially the basis of diet exercise control is good, then the use of Yousiling can make the blood sugar reach the standard, and the cost performance is higher. If the subject&;s blood sugar fluctuates greatly and there are many variations, the effect of using Yousiling on sugar control may be relatively limited. The specific application should be based on personal illness and living conditions, and the doctor should draw up a suitable plan and adjust it regularly.
