Laboratory tests Elevated urate concentration in the blood, normal values are 70mg/L for men and 60mg/L for women, with high values up to 180mg/L or more. The rate of blood cell sedimentation is fast during the attack, and NPN is elevated; joint fluid microscopy shows urate crystals. 1.X-ray plain film has joint swelling in the early stage, and worm-like or chisel-like defects at the proximal end of the joint in the later stage, joint space narrowing in the late stage, extensive bone destruction and obvious soft tissue swelling in the severe cases, and calcification shadow can be seen in the calcified gout stone. 2.CT and MRI examinations: can help in the early diagnosis of this disease and can be used as appropriate. Treatment For patients with elevated blood uric acid, even if the disease does not develop, attention should be paid to diet moderation, abstain from eating a diet containing high purine, avoid alcohol abuse, overwork and mental stimulation. If the blood uric acid exceeds 80mg/L, you should take uric acid excreting drugs, such as propofol, 1-2mg/d, in 2 oral doses, and drink more water. For those who have developed symptoms, regular treatment should be carried out in time. 1, general treatment bed rest, local cold compress, drink more water to increase the excretion of uric acid. 2.Pharmacologic therapy clinically, mostly with colchicine 1mg, once every 2 hours, until the symptoms are controlled or a reaction, manifested as nausea, vomiting or diarrhea, generally begin to reduce swelling after 12h of taking the drug, the total amount of 4-8mg per day. 0,5mg, 3 times / d later, 1-2 days after the pain can disappear completely. The daily dose of the drug does not exceed 3mg for those with poor kidney function. During the course of taking the drug, the white blood cells should be checked, and the dose should be reduced or stopped when it decreases. For those with heavy gastrointestinal reaction, it can be changed to intravenous injection, 1-3mg each time, add 20ml saline and inject slowly, repeat once every 6-8h when needed, avoid leakage of drug when injecting. After the symptoms are relieved, colchicine 0,5mg can be given intermittently, 3 times/d, or with pautazone or indomethacin. Abstain from high purine food and drink more water; when blood uric acid is high, take propoxur as above. Other medications include: (1) POTAXONE: 400mg for the first dose, 200mg every 4-6 hours thereafter; after symptoms are controlled, 100mg 3 times/d. This drug can replace colchicine. (2) Indomethacin: 150mg for the first dose, 100mg every 4-6 hours thereafter, 3-4 times in a row. From the next day onwards, 50mg each time, 3 times/d. 3.Surgical treatment If the gout stone is in danger of wearing out or impeding joint movement and wearing shoes and socks, it should be surgically removed, and those who have ruptured and formed sinus tracts should be scraped out and implanted as appropriate.
