Abstract

The invention discloses enterobacteriaeae Catabacter pertinent to nephrotic syndromes. The inventor of the invention finds that the enterobacteriaeae Catabacter is pertinent to the nephrotic syndromesfor the first time, the abundance of the enterobacteriaeae Catabacter in the nephrotic syndromes is notably reduced, which indicates that the enterobacteriaeae Catabacter can be used as a microorganism marker for diagnosing the nephrotic syndromes, and further individualized treatment is realized.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and relates to an intestinal genus related to nephrotic syndrome, and the genus is Catabacter. Background technique

[0002] Nephrotic syndrome (NS) is a group of clinical syndromes with severe proteinuria, hypoalbuminemia, hyperlipidemia and edema as its main manifestations. Threat to human health. At present, the treatment of NS mainly adopts immunosuppressant therapy, which has achieved certain curative effect. However, the prognosis of NS is closely related to the type of renal pathological changes, and the curative effect is different. Moreover, many patients develop tolerance to the above drugs, or are forced to stop the drugs due to serious adverse reactions. Finally, it develops into advanced renal failure, which brings a heavy economic burden to the patient. Therefore, it is imminent to deeply explore the pathogenesis of NS and find safe and effective therapeutic drugs.

[0066] 1.1 Construction of membranous glomerulonephritis model

[0067] Sprague-Dawley rats were used as experimental animals, referring to the Border method (Border WA, Ward HJ, KamilES, et al. Induction of membraneous nephropathy in rabbits by administration of an exogenous cationic antigen. J Clin Invest, 1982, 69: 451-461) , using C-BSA to immunize rats to reproduce a typical and stable model of membranous glomerulonephritis.
