Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown: the present invention first analyzes the differential tsRNA in seminal plasma exosomes of non-obstructive azoospermia, obstructive azoospermia and healthy control population, and then analyzes the selected differential tsRNA in more non-obstructive azoospermia, Perform real-time fluorescent quantitative PCR verification in samples from patients with obstructive azoospermia, severe spermatogenic dysfunction and healthy controls, and finally determine whether the screened tsRNA is present in testicular tissue samples from patients with obstructive azoospermia and non-obstructive azoospermia Whether there is a difference in expression, to further determine its feasibility as a diagnosis of non-obstructive azoospermia, and conduct bioinformatics functional analysis to determine its possible regulatory mec...

Abstract

The invention discloses a seminal plasma exosome tsRNA marker related to the diagnosis of non-obstructive azoospermia and its application. The markers are tRF-Pro-AGG-003 and tRF-Val-AAC-010, the sequence of tRF-Pro-AGG-003 is SEQ ID NO.1, and the sequence of tRF-Val-AAC-010 is SEQ ID NO. 2. The marker has specificity and sensitivity to non-obstructive azoospermia, and can be used to prepare a diagnostic kit for non-obstructive azoospermia. The two seminal plasma exosome markers tRF-Pro-AGG-003 and tRF-Val-AAC-010 of the present invention are differentially expressed in the seminal plasma of patients with non-obstructive azoospermia and obstructive azoospermia, which can be compared with It can diagnose non-obstructive azoospermia well, and can predict the result of sperm retrieval in azoospermia, and its effect is better than commonly used indicators such as plasma follicle stimulating hormone level and testicular volume.

Description

technical field [0001] The invention relates to the fields of biological diagnosis and medicine, in particular to a seminal plasma exosome tsRNA marker related to the diagnosis of non-obstructive azoospermia and its application. Background technique [0002] The incidence of azoospermia accounts for 10%-20% of male infertility. According to the presence or absence of sperm in the testis, it can be divided into two categories: one is obstructive azoospermia (OA) with normal spermatogenesis in the testis. The other is non-obstructive azoospermia (NOA), which is a disorder of testicular spermatogenesis. An accurate diagnosis of non-obstructive azoospermia can provide valuable guidance to clinicians. Although conventional biochemical markers in semen, such as citric acid, acid phosphatase, fructose, and α-glucosidase, can be used to assist in the diagnosis of OA patients; testicular volume, serum follicle-stimulating hormone (FSH) levels, etc. can be used to assist in the diag...
