Embodiment 1

[0022] Methodology for screening prognostic markers combining transcriptomic profiling and clinical indicators

[0023] (1) Acquisition of discovery queue

[0024] The cohort used for transcriptome sequencing in the present invention comes from the prospective DN cohort of Nanjing General Hospital and National Clinical Research Center of Nephrology. Among them, the conditions for DN patients to enter the group: a) age ≥ 18 years old; b) patients with type 2 diabetes (WHO diagnostic criteria) accompanied by DN admitted to the Nanjing General Hospital of Nanjing Military Region and the National Clinical Research Center for Kidney Diseases diagnosed by renal biopsy , excluding other concomitant renal diseases; c) signed informed consent; d) on the basis of complete routine pathological examination, with renal tissue micro-separation; e) at least 1 year follow-up, at least 2 eGFR follow-up points per year; DN was included in the group 61 patients. Clinical data such as renal tis...

Embodiment 2

[0030] Application of SLPI as a prognostic marker for DN

[0031] (1) RT-PCR

[0032] The renal tissue paraffin specimens of DN patients were sectioned to LEICA laser microseparation special sections, freshly prepared xylene for dewaxing, dehydrated with gradient alcohol, and then the renal tubular tissue was separated by laser microseparation, and the tubular tissue was extracted with the FFPE RNA extraction kit purchased from QIAGEN Company. The total RNA obtained from , was determined by a two-step method: the first step was reverse transcription, and the mRNA was reverse transcribed to synthesize cDNA according to the kit instructions. The reaction conditions were: 25°C, 10min, 37°C, 120min, 85°C, 5min; Step 2: Real-time PCR reaction, using SLPI and 18s as primers, the reaction conditions are: 95℃, 30s, 95℃, 5s, 60℃, 34s, cycle 40 times, 95 ℃, 15s, 60℃, 1min, 95℃, 15s, record and observe the amplification curve and dissolution curve, determine the amplification product as...

Abstract

The invention discloses the use of secreted leukocyte protease inhibitor SLPI as a prognostic marker of diabetic nephropathy DN. The present invention confirms through research: the expression of SLPI in renal tubular epithelial cells of DN patients increases, and the expression in urine also increases, and is significantly correlated with the decline slope of glomerular filtration rate (eGFR) of DN patients, which can predict the decline rate of patients with DN. prognosis. The inventors found that the mRNA and protein levels of SLPI in the renal tubules of DN patients were significantly increased by detecting the renal tissue sections and urine of DN patients, and the expression level of SLPI in urine increased in parallel with the renal protein level, and could effectively predict the prognosis of DN patients. And better than serum creatinine or proteinuria.

Description

technical field [0001] The invention belongs to the technical field of gene biological preparations, in particular to the application of a secreted leukocyte protease inhibitor SLPI in the field of diabetic nephropathy DN. Background technique [0002] Diabetic nephropathy (DN) is one of the most common microvascular complications of diabetes. With the increasing prevalence of diabetes in my country, the incidence of DN also increases. Investigations show that DN has surpassed glomerulonephritis and become the primary cause of chronic kidney disease (CKD) in hospitalized patients in my country. Survey data in the United States in the past 20 years show that under the background of effective control of important complications of diabetes, such as cardiovascular and cerebrovascular events, the incidence of end-stage renal disease (ESRD) caused by diabetes is not obvious. The diagnosis of DN also depends on clinical diagnosis and pathological diagnosis, and the treatment is m...
