The main symptoms of acute nephritis are hematuria and facial edema, and hematuria is almost always visual hematuria, which can be seen directly and cannot be determined by taking a pulse. The main symptoms of chronic nephritis are hematuria, edema, hypertension, and urine protein. Hypertension can only be measured by a blood pressure monitor, and the value of blood pressure cannot be determined by taking the pulse. The majority of hematuria in patients with chronic nephritis is microscopic hematuria, which can only be determined by urine routine, and cannot be determined by taking a pulse. Urine protein is a routine test item in the urine routine, which cannot be determined by pulse taking. The pulse is a Chinese medicine technique that can only determine the disease of Chinese medicine, while nephritis is a Western medicine disease, there is no nephritis in Chinese medicine, so taking the pulse to determine nephritis is nonsense.
