Music as a non-pharmacological nursing intervention can be used as complementary adjunct in the care of patients with low-energy states who tire easily, such as those requiring mechanical ventilator support.

Engineered functional organs or tissues, created with autologous somatic cells and seeded on biodegradable or hydrogel scaffolds, have been developed for use in individuals with tissue damage suffered from congenital disorders, infection, irradiation, or cancer. However, in those patients, abnormal cells obtained by biopsy from the compromised tissue could potentially contaminate the engineered tissues. Thus, an alternative cell source for construction of the neo-organ or functional recovery of the injured or diseased tissues would be useful. Recently, we have found stem cells existing in the urine. These cells are highly expandable, and have self-renewal capacity, paracrine properties, and multi-differentiation potential. As a novel cell source, urine-derived stem cells (USCs) provide advantages for cell therapy and tissue engineering applications in regeneration of various tissues, particularly in the genitourinary tract, because they originate from the urinary tract system. Importantly, USCs can be obtained via a non-invasive, simple, and low-cost approach and induced with high efficiency to differentiate into three dermal cell lineages.

In this paper, we evaluated the historical features and physical examination findings, as well as laboratory tests and ultrasound examinations, in children with testicular torsion (TT), in order to improve diagnosis and treatment in this population. A retrospective review of patients with diagnosis of TT between January 1990 and January 2010 was performed. We included 118 cases in the study, accounting for 9.01% of all cases of acute scrotum. Mean patient age was 9.3 ± 5.6 years. The left side was predominantly affected. The median duration of symptoms up to surgical exploration was 64 h. Absence of cremasteric reflex presented in 94.9% patients. All boys had an ultrasound of the scrotum; decreased or absent blood flow was observed in all orchidectomy patients. Heterogeneous echogenicity presented in all cases of orchidectomy. At surgery, viable testes were present in 46 boys (39%) and preserved; in 72 boys with nonviable testes, they were removed. The median duration of symptoms at presentation was 12 h when the testes were successfully conserved and 90 h when they were removed. Testicular salvage depends critically on early surgical intervention. Ultrasound is a useful tool for the clinical assessment of patients with TT, however, sonographic interpretation must be in conjunction with the clinical manifestations. We advocate immediate surgical exploration with suspected TT. Long-term hormonal levels are within the normal range regardless of the fate of the testis. Further follow-up is needed to confirm fertility after TT.

The lncRNA XIST (X inactive-specific transcript) is an oncogenic lncRNA that is present in various malignant tumors; however, its role and molecular mechanisms in osteosarcoma (OS) progression remain unclear. In the current study, 40 pairs of OS tissues and matched adjacent non-tumor tissues were collected. qRT-PCR was conducted to investigate the differences in XIST expression in tissues and OS cell lines. The proliferation, invasion, and EMT status of OS cells after transfection were assessed with WST-1 assays, Transwell assays, and Western blot analysis, respectively. Whether miR-195-5p was a direct downstream target of XIST was verified by both bioinformatics target gene prediction and dual-luciferase report analysis. A mouse model was established to evaluate tumor proliferation in vivo. Our results demonstrated that XIST expression was significantly upregulated in OS tissues and cell lines and negatively correlated with clinical prognosis. XIST knockdown inhibited cancer cell proliferation and invasion in vitro, inhibited the EMT of OS cells in vitro, and suppressed subcutaneous tumor growth in vivo. Further analysis demonstrated that XIST regulated YAP expression by functioning as a competing endogenous RNA that sponged miR-195-5p in OS cells. XIST directly interacted with miR-195-5p and decreased the binding of miR-195-5p to the YAP 3'UTR, which suppressed the degradation of YAP mRNA by miR-195-5p. In conclusion, this work demonstrates that lncRNA XIST enhances OS cancer cell proliferation and invasion in part through the miR-195-5p/YAP pathway. Therefore, lncRNA XIST might be a promising therapeutic target for OS.
