[Impacts of different procedures of testicular sperm retrieval on testicular function and antisperm antibodies in azoospermia patients].

Objective: To investigate the influence of different procedures of testicular sperm retrieval on the levels of serum inhibin B (INHB), antisperm antibodies (AsAb), follicle-stimulating hormone (FSH), and testosterone (T) in patients with azoospermia.

Methods: We randomly assigned 210 azoospermia patients to receive testicular sperm extraction (TESE, n = 50), testicular sperm aspiration (TESA, n = 56), testicular fine needle aspiration (TEFNA, n = 64), or microscopic TESE (micro-TESE, n = 40). We measured the levels of serum INHB, FSH, and T and the positive rate of AsAb before and at 1 and 3 months after surgery.

[Degradation of the Nitrogenous Heterocyclic Compound Quinoline by O/UV].

The influences of various factors including initial concentration of quionline solution, static duration after reaction, initial pH, HCOon the degradation of quinoline by O/UV were analyzed in this study. In addition, the degradation mechanism and pathways were also analyzed. The results showed that reaction rate constants and removal rate of quinoline decreased with the increase of the initial concentration of quinoline.
