[Abundances and Morphology Patterns of Microplastics Under Different Land Use Types on the Loess Plateau].

As an emerging pollutant to the environment, microplastics have received widespread attention worldwide. The Loess Plateau, as one of the major agricultural production areas in China, has various land use types, but how the abundance and morphological patterns of microplastics differ among soils under different land use types remains unclear. In this study, we collected soils from three different land use types:croplands, apple orchards, and landfills in the Wangdonggou Catchment.

microRNA-486-5p is implicated in the cisplatin-induced apoptosis and acute inflammation response of renal tubular epithelial cells by targeting HAT1.

The proinflammatory property of cisplatin is potentially destructive and contributes to the pathogenesis of acute kidney injury (AKI). The role and upstream regulatory mechanism of histone acetyltransferase 1 (HAT1) in acute kidney inflammation are still unknown. We performed RNA sequencing to filter differentially expressed microRNAs (miRNAs) in the kidney tissue of mice with AKI induced by cisplatin and ischemia-reperfusion.

Long Non-coding RNA MEG3 Promotes Pyroptosis in Testicular Ischemia-Reperfusion Injury by Targeting MiR-29a to Modulate PTEN Expression.

Increasing evidence shows that the abnormal long non-coding RNAs (lncRNAs) expression is closely related to ischemia-reperfusion injury (I/R) progression. Studies have previously described that lncRNA MEG3 regulates pyroptosis in various organs I/R. Nevertheless, the related mechanisms of MEG3 in testicular I/R has not been clarified.

[Novel coronavirus induces testicular injury: Analysis of causes and follow-up monitoring].

The outbreak of coronavirus disease 2019 (COVID-19) caused by 2019 novel coronavirus has become a global public health challenge. In addition to the typical respiratory symptoms, COVID-19 can induce damage to testicular spermatogenesis. This study focuses on the possible causes and follow-up monitoring of testicular injury induced by COVID-19.

[Effect of testicular autophagy on spermatogenic cells in varicocele rats].

Objective: To study the effect of different levels of autophagy in the testis on the apoptosis of spermatogenic cells in the rat model of varicocele (VC).

Methods: We randomly divided 54 SD male rats into six groups, blank control (n = 6), rapamycin control (n = 6), chloroquine control (n = 6), VC model control (n = 12), VC + rapamycin (n = 12), and VC + chloroquine (n = 12). We observed the histomorphological changes of the testis and epididymis by HE staining, obtained the scores on spermatogenesis in the testis and epididymis, calculated the apoptosis index (AI) of the testicular spermatogenic cells by TUNEL, and determined the expressions of LC3-Ⅱ, LC3-Ⅰ, p62, Bax and Bcl-2 proteins in the testis tissue by Western blot.

Autophagy may play an important role in varicocele.

The present study aimed to determine the expression of autophagy and investigate whether the hypoxia‑inducible factor 1α (HIF‑1α)/BCL2 interacting protein (BNIP3)/Beclin‑1 autophagy signaling pathway serves an important role in activating autophagy in varicocele (VC) rat testes cells. Furthermore, the current study aimed to explain the possible association between autophagy and apoptosis. A total of 48 adult male Sprague Dawley rats were divided into group A (control), group B (VC 15‑day), group C (VC 30‑day) and group D (VC 45‑day), with 12 rats in each group.

Treatment of renal uric acid stone by extracorporeal shock wave lithotripsy combined with sodium bicarbonate: 2 case reports.

Uric acid stone is the most comment radiolucent renal stone with high recurrence rate, which would further cause acute upper urinary tract obstruction and kidney failure. Here we report two cases of renal uric acid stone from December 2012 to April 2013. One 43-year-old male patient suffered from chronic uric acid nephrolithiasis caused by the long-term indwelling of bilateral double-J stent.

Overexpression of immunoglobulin G prompts cell proliferation and inhibits cell apoptosis in human urothelial carcinoma.

Only B lymphocytes can express immunoglobulins according to the traditional immunological theories, and the expression of immunoglobulin G (IgG) messenger RNA (mRNA) and protein was found in certain human cancer cells recently. However, the expression pattern of IgG and its possible role in human urothelial carcinoma are still elusive. In this study, we investigated the expression of IgG in two human urothelial carcinoma cell lines, T24 and BIU-87, and in 56 cases of clinical urothelial carcinoma tissues.

[Urethroplasty with oblique preputial island flap for the treating of hypospadia].

Objective: To Explore the effect of oblique preputial island flap for the treating of hypospadias.

Methods: Fifty-one patients were performed one-stage urethroplasty with oblique preputial island flap to repair hypospadias.

Results: All cases resulted in a good contour of the penis without any redundancy and a normal anatomic position of slit-shaped urethral meatus.

[Influence of male genital bacterial infection on sperm function].

Male infertility is related to urogenital tract bacterial infection. The significance of bacteriosperimia for male infertility has been paid attention in recent years. Asymptomatic bacteriosperm may play an important role.
