The main signs of spinal consumption, one of the manifestations of spinal syphilis, are loss of knee and ankle reflexes, impaired vibration and position sensation in the lower extremities, and a positive closed-eye refractory sign. Spinal syphilis is an important type of central nervous syphilis, including spinal consumption, spinal membranous vascular syphilis, and syphilitic myelitis. Syphilitic myelitis is also called syphilitic spinal myelitis because the lesions often involve the spinal membrane. What are the examination methods? 1, cerebrospinal fluid examination is a sensitive indicator of neurosyphilis activity, neurosyphilis patients often show abnormalities, increased cell count, in (200-300) × 106 / L, mostly lymphocytes and a small number of plasma cells and monocytes. Cerebrospinal fluid protein is elevated, 0.4 to 2 g/L, cerebrospinal fluid IgG is elevated, and sugar is generally normal. 2.Serological test of syphilis includes non-specific STD investigation test, flocculent test and specific dense spirochete immunofluorescence adsorption test and dense spirochete braking reaction. 3.Blood routine Blood routine is the most general, the most basic blood test. Routine blood test is usually taken with peripheral blood, such as blood from fingertips and earlobes. After the blood cell analysis instrument, the computer reports the results, and this item has become a practice to examine patients. Blood consists of two major parts, liquid and tangible cells, and routine blood tests are performed on the cellular part of the blood. Blood has three different functions of cells – red blood cells (commonly known as red blood cells), white blood cells (commonly known as white blood cells), and platelets. Diseases are determined by observing changes in number and morphological distribution. It is one of the common auxiliary tests for doctors to diagnose the disease. 4.Blood biochemistry six items The blood biochemistry six items examination is a preliminary examination of human blood condition, including alanine aminotransferase, creatinine, urea nitrogen, serum glucose, triglyceride, total cholesterol examination. The diagnosis is not difficult based on smut history, syphilis infection history, spinal cord damage manifestation, typical a-ro pupil, positive VDRL and FTA-ABS in serum and cerebrospinal fluid.
