Renal tubular injury caused by oxidative stress and inflammation results in acute kidney injury. Recent research reported that antibiotics may protect renal tubules from progressive deterioration, but the underlying mechanism remains unclear. Therefore, we investigated the efficacy and mechanism of action of antibiotics against renal tubular injury. ⋯ This indicates that ciprofloxacin enhances autophagy, increasing the amount of free Beclin-1 via phosphorylated Bcl-2, and inhibits caspase activity. Therefore, ciprofloxacin might protect against renal tubular injury through the activation of autophagy in the setting of acute kidney injury.

This study explores the clinical efficacy of intra-articular injection of chitosan combined with low-dose glucocorticoid for the treatment of knee osteoarthritis in early and middle stages. The visual analog scale (VAS) score, Lysholm score, Hospital for Special Surgery (HSS) score, and changes in the levels of inflammatory cytokines IL-1, IL-6, and TNF-α in the joint fluid before and after treatment in the 3 groups were compared, and the clinical efficacy was evaluated. All cases were followed up, with a follow-up time of 7 to 12 months, and no lost cases. ⋯ The difference in clinical efficacy among the 3 groups was statistically significant (P < .05). The clinical efficacy of chitosan combined with low-dose glucocorticoid intra-articular injection in the treatment of knee osteoarthritis in early and middle stages is significant, with the characteristics of small trauma, rapid onset, and lasting efficacy, and it avoids the adverse reactions of topical or oral nonsteroidal anti-inflammatory drugs. As a first-line treatment option, it is recommended for promotion and use in clinical practice.

This study aimed to explore the experiences of barriers and facilitators to the implementation of narrative nursing by junior nurses. Participants were recruited using purposive sampling. Semi-structured interviews were conducted from October 2023 to February 2024. ⋯ Relevant barriers include lack of practical skills related to narrative nursing, neglect of the concept of humanistic care, negative events, high workload for junior nurses, restricted implementation environment. The facilitators contain patients' and family members' trust, training related to knowledge and skills, as well as harmonious and cooperative working atmosphere. There is still room for improvement in the implementation of narrative nursing for junior nurses, and the systematic training of narrative nursing knowledge and skills should be enhanced; the medical humanistic environment should be optimized; and the psychological resilience of junior nurses should be improved, so as to encourage them to actively implement narrative nursing at the early stage of their careers, and to deepen the high-quality development of nursing humanism.

Kneeling and half-kneeling training are common positions used in physical therapy. however, research on lower extremity muscle activity is lacking compared to the ergonomic aspects and trunk muscle activity. The purpose of this study is to investigate the effects on lower extremity muscle activity during squats in kneeling and half-kneeling positions. The study was designed as a cross-sectional study with a single group of healthy adults. ⋯ In the HKP, there were statistically significant differences between the ascent and descent phases of the RF, GMax, and GMed (P < .05). The results of this study indicate that squats in the HKP (especially during the ascent phase) require the highest muscle activity, whereas squats in the KP (especially during the descent phase) can be performed with the lowest muscle activity. It can be concluded that these findings could serve as selective indicators for squat exercises and in enhancing postural control, muscle strength, and lower extremity stabilization.

Oxidative stress is an essential contributor to the progression of chronic obstructive pulmonary disease (COPD). A systematic assessment of diet patterns and lifestyle with the oxidative balance score (OBS) to reflect oxidative stress levels will help predict the risk of COPD. This study conducted a cross-sectional analysis to assess the link between OBS and COPD. 5162 participants were collected from 2013 to 2018 from the National Health and Nutrition Examination Survey (NHANES). ⋯ The smoothed curve fitting supported the negative association between OBS and COPD. Subgroup analyses revealed that the protective effect of OBS was notably pronounced among the non-hypertensive and non-diabetic populations. These findings suggest a negative link between OBS and COPD, underscoring the importance of antioxidant-rich diets and lifestyles in preventing COPD.
