1, more men than women: men account for 78.1~95%, 40~60 years old, with the improvement of people’s living standards, in recent years the onset of the trend has been younger. 2, from the bottom up: often the lower limb joints are the first to be involved, the first arthritis to the metatarsophalangeal joints are common, accounting for 50% to 70%, followed by the dorsal foot, ankle, heel, knee, wrist, finger and elbow joints, and eventually any joint of the extremities. 3, good at night attack: often sudden onset at night, pain is unbearable, the patient often barefoot rushed to the hospital for help. 4. Self-remission: Without treatment, the arthritis may resolve on its own in some patients in about 1 week. 5. Recurring: Arthritis can recur, making it difficult to prevent. The recurring attacks are mostly single joint or multi-joint alternating attacks. Uric acid crystals can be detected in the synovial fluid during the attacks, and crystal deposits can form gout stones over time, leading to joint deformity and disability; they can also involve the kidneys, forming uric acid kidney stones and gouty nephropathy. 6, high blood uric acid: serum uric acid level is higher than 6.8mg/dl, a few patients can also be in the normal range. 7, treatment divided into urgent: the acute phase should be actively controlled inflammation, early standardized treatment, rapid relief of joint symptoms, otherwise easy to delay; remission treatment to control blood uric acid, but before starting treatment with uric acid-lowering drugs, patients should take low doses of colchicine or non-steroidal anti-inflammatory drugs, so as not to induce acute gout attack. 8, treatment and prevention of excess: to prevent the long-term over-application of anti-inflammatory drugs for the treatment of acute gouty arthritis, some of which have even caused irreversible pharmacological kidney damage; to prevent the failure to reduce xanthine oxidase inhibitors or pro-uric acid excretory drugs to the lowest maintenance dose when blood uric acid control has been achieved; also to prevent over-treatment with uric acid-lowering drugs for asymptomatic hyperuricemic patients. However, both asymptomatic hyperuricemia and symptomatic gout patients must be treated for concurrent combined hypertension, diabetes mellitus, coronary heart disease, obesity and alcoholism. 9, depending on the diet: should drink more water, oral sodium bicarbonate tablets alkalize urine to promote uric acid excretion; should control purine intake, to avoid purine-rich foods, such as animal offal, brain, mixed beans, gravy, etc.; should also strictly abstain from smoking and alcohol, including alcoholic beverages and drugs.
