RESUMEN
INTRODUCTION: Music interventions can alleviate patient anxiety and improve post-surgical satisfaction. However, it remains uncertain whether personal music preferences affect efficacy. The authors tested whether personal music intervention with patient-selected songs played ad libitum is more effective than standard therapist-designed treatment with classical music. METHODS: A prospective, parallel-group, single-blinded, randomized controlled trial with 229 participants (aged 18-60 years) previously scheduled for elective surgery. Data analyses followed a modified intention-to-treat principle. The patients were randomized into three groups: Standard care without music (Control), therapist-designed classic music treatment (TT), or personal music intervention with patient-selected songs played ad libitum by the patient (PI). All patients received standard post-anaesthesia care, and music intervention was started upon arrival at the post-anaesthesia care unit. Primary outcomes were anxiety and overall satisfaction at discharge. In contrast, secondary outcomes were systolic blood pressure during music intervention, the sleep quality of the night after surgery, and the occurrence of postoperative nausea and vomiting within the first 24 h after surgery. RESULTS: Compared with therapist-designed music treatment, personal intervention decreased systolic blood pressure (T 0 : 124.3±13.7, 95% CI:121-127.7; T 20min : 117.6±10.4, 95% CI:115-120.1; T 30min : 116.9±10.6, 95% CI:114.3-119.4), prevented postoperative nausea and vomiting (Control: 55.9%, TT: 64.6%, PI: 77.6%), including severe postoperative nausea (VAS score>4; Control: 44.1%; TT: 33.8%; PI: 20.9%) and severe emesis (Frequency≥3, Control: 13.2%; TT: 7.7%; PI: 4.5%). None of the treatments affected sleep quality at night after surgery (Median, Q1-Q3, Control: 3, 1-3; TT: 3, 1-4; PI: 3, 1-3.5). Personal, but not therapist, music intervention significantly prevented anxiety (Control: 36.4±5.9, 95% CI:35.0-37.9; TT: 36.2±7.1, 95% CI: 34.4-37.9; PI: 33.8±5.6, 95% CI: 32.4-35.2) and emesis (Control: 23.9%; TT: 23.4%; PI: 13.2%) and improved patient satisfaction (Median, Q1-Q3, C: 8, 6-8; TT: 8, 7-9; PI: 8, 7-9). CONCLUSIONS: Personal music intervention improved postoperative systolic blood pressure, anxiety, nausea, emesis, and overall satisfaction, but not sleep quality, as compared to therapist-designed classic intervention.

Background: Breathing exercise can help patients with dyspnea to change the wrong breathing pattern, improve the degree of freedom of respiratory muscles, increase alveolar ventilation, promote breathing, and relieve the symptoms of dyspnea patients. Therefore, this study is aimed at investigating the role of breathing training in alleviating postoperative pain in patients with spinal nerve root entrapment syndrome. Objective: To explore the effect of respiratory training in relieving postoperative pain in patients with spinal nerve root entrapment syndrome. Methods: Fifty-eight patients with spinal nerve root entrapment syndrome treated in our hospital from May 2020 to May 2021 were analyzed retrospectively. The patients were randomly divided into a control group (n = 29) and an observation group (n = 29). The control group was given routine postoperative pain nursing, and the observation group was given respiratory training on the basis of the control group. The scores of visual analogue scale (VAS), self-rating anxiety scale (SAS), Oswestry dysfunction index questionnaire (ODI), the dosage of postoperative analgesics, and the time of first out-of-bed activity were recorded before pain nursing intervention and 3 days and 7 days after intervention. Results: The VAS, SAS, and ODI scores of the observation group after 3 d and 7 d of intervention were lower than those of the control group. Compared with the same group, the scores of VAS, SAS, and ODI after 3 d and 7 d of intervention were lower than those before intervention, and those after 7 d of intervention were lower than those after 3 d of intervention (P < 0.05). The dosage of postoperative analgesics and the time of first out-of-bed activity in the observation group were lower than those in the control group (P < 0.05). Conclusion: Respiratory training can effectively relieve postoperative pain, reduce anxiety, and improve spinal function in patients with spinal nerve root entrapment syndrome, which is beneficial to the prognosis of patients and is worthy of promotion.

BACKGROUND: Neurodegenerative diseases, such as Alzheimer's disease, and traumatic brain and spinal cord injury (SCI) are prevalent in clinical practice. Inhibition of hyperactive inflammation and proliferation of endogenous neural stem cells (NSCs) is a promising treatment strategy for SCI. Our previous studies demonstrated the beneficial effects of rosiglitazone (Rosi) on SCI, but its roles in inflammation inhibition and proliferation of NSCs are unknown. METHODS: SCI in a rat model was established, and the effects of Rosi on motor functions were assessed. The effects of Rosi on NSC proliferation and the underlying mechanisms were explored in details. RESULTS: We showed that Rosi ameliorated impairment of moto functions in SCI rats, inhibited inflammation, and promoted proliferation of NSCs in vivo. Rosi increased ATP production through enhancing glycolysis but not oxidative phosphorylation. Rosi reduced mitophagy by downregulating PTEN-induced putative kinase 1 (PINK1) transcription to promote NSC proliferation, which was effectively reversed by an overexpression of PINK1 in vitro. Through KEGG analysis and experimental validations, we discovered that Rosi reduced the expression of forkhead box protein O1 (FOXO1) which was a critical transcription factor of PINK1. Three FOXO1 consensus sequences (FCSs) were found in the first intron of the PINK1 gene, which could be potentially binding to FOXO1. The proximal FCS (chr 5: 156680169-156680185) from the translation start site exerted a more significant influence on PINK1 transcription than the other two FCSs. The overexpression of FOXO1 entirely relieved the inhibition of PINK1 transcription in the presence of Rosi. CONCLUSIONS: Besides inflammation inhibition, Rosi suppressed mitophagy by reducing FOXO1 to decrease the transcription of PINK1, which played a pivotal role in accelerating the NSC proliferation.

Radiation-induced acute intestinal injury is a common and serious occurrence following abdominal and pelvic irradiation. The Nod-like receptor protein 3 (NLRP3)-dependant inflammasome and inflammation activation is crucial in this process. In a pre-experimental design of radiation-induced intestinal injury, we found that rosiglitazone inhibited caspase-1 which is a key marker of inflammasome activation. The purpose of the present study was to clarify the inhibitory effect of rosiglitazone on the NLRP3 inflammasome both in vivo and in vitro. Radiation-induced intestinal injury after rosiglitazone treatment, and the expression of interleukin-1ß (IL-1ß), tumor necrosis factor-α (TNF-α), caspase-1 and NLRP3 in a radiation-induced intestinal injury model in a rat and macrophages were observed. We found that rosiglitazone ameliorated radiation-induced intestinal injury in rats by suppressing the expression of caspase-1, NLRP3, IL-1ß and TNF-α. Treatment with rosiglitazone in vitro reduced the expression of NLRP3, and the NLRP3 activator monosodium urate (MSU) reversed the inhibition of IL-1ß and TNF-α by rosiglitazone in macrophages. MSU reversed the protective effect of rosiglitazone on radiation-induced intestinal injury in rats by reversing the rosiglitazone-induced inhibition of IL-1ß and TNF-α. Taken together, these findings indicate that the peroxisome proliferator-activated receptor gamma (PPARγ) agonist, rosiglitazone, ameliorates radiation-induced intestine inflammation in rats via inhibiting the induction of the NLRP3-dependent inflammasome in macrophages.

Persistent inflammation disrupts functional recovery after spinal cord injury (SCI). Peroxisome proliferator-activated receptor gamma (PPAR-γ) activation promotes functional recovery in SCI rats by inhibiting inflammatory cascades and increasing neuronal survival. We sought to clarify the relationship between PPAR-γ activation and NACHT, LRR and PYD domain-containing protein 3 (NLRP3) inflammasome suppression, and the role of NF-κB in activating the NLRP3 inflammasome in neurons. In SCI rats, we found that rosiglitazone (PPAR-γ agonist) inhibited the expression of caspase-1. In in vitro neurons, G3335 (PPAR-γ antagonist) reversed the rosiglitazone-induced inhibition of caspase-1, interleukin 1 (IL-1ß), and interleukin 6 (IL-6). Rosiglitazone inhibited the expression of NLRP3, caspase-1, IL-1ß, and IL-6. However, the activator of NLRP3 could counteract this inhibition induced by PPAR-γ activation. NF-κB did not participate in the process of rosiglitazone-induced inhibition of NLRP3. Consistent with our in vitro results, we verified that locomotor recovery of SCI rats in vivo was regulated via PPAR-γ, NLRP3, and NF-κB. These results suggest that PPAR-γ activation exerts an anti-inflammatory effect by suppressing the NLRP3 inflammasome-but not NF-κB-in neurons and that PPAR-γ activation is a promising therapeutic target for SCI.

The peroxisome proliferator-activated receptor gamma (PPAR-γ) agonist rosiglitazone inhibits NF-κB expression and endogenous neural stem cell differentiation into neurons and reduces the inflammatory cascade after spinal cord injury (SCI). The aim of this study was to explore the mechanisms underlying rosiglitazone-mediated neuroprotective effects and regulation of the balance between the inflammatory cascade and generation of endogenous spinal cord neurons by using a spinal cord-derived neural stem cell culture system as well as SD rat SCI model. Activation of PPAR-γ could promote neural stem cell proliferation and inhibit PKA expression and neuronal formation in vitro. In the SD rat SCI model, the rosiglitazone + forskolin group showed better locomotor recovery compared to the rosiglitazone and forskolin groups. MAP2 expression was higher in the rosiglitazone + forskolin group than in the rosiglitazone group, NF-κB expression was lower in the rosiglitazone + forskolin group than in the forskolin group, and NeuN expression was higher in the rosiglitazone + forskolin group than in the forskolin group. PPAR-γ activation likely inhibits NF-κB, thereby reducing the inflammatory cascade, and PKA activation likely promotes neuronal cell regeneration.
RESUMEN
This paper studied the effects of two amendments (iron sulfate[Fe2 (SO4)3] and calcium carbonate[CaCO3]) on the bioavailability of Pb, Cd and As in a garden soil and on the migration and accumulation of Pb, Cd and As in pepper through an in-situ experiment planting pepper plants. The results indicated that:â Addition of these amendments significantly decreased TCLP extractable contents of Pb and Cd in soil, and increased TCLP extractable contents of As.â¡Compared with the control group, addition of Fe2 (SO4)3 led to reduction in contents of Pb and Cd in pepper fruits by 7.2%-22.9% and 2.3%-2.9%, respectively, but no obvious changes were observed for As contents in pepper fruits. Meanwhile, addition of CaCO3 decreased the contents of Pb, Cd and As in pepper fruits by 15.8%-16.3%, 11.8%-15.0%, and 0.03%-53.2%, respectively. â¢The maximum reductions for the translocation factors of Pb, Cd and As from stem to fruits in pepper plants were 16.7%, 68.0%, 10.2%, respectively, due to Fe2(SO4)3 application and 16.7%, 51.5%, 45.6%, respectively, due to CaCO3 application, compared with the control group. It was obvious that Fe2 (SO4)3 and CaCO3 could both effectively decrease the migration of soil Pb, Cd and As to pepper plants, but the effects of CaCO3 were better than those of Fe2 (SO4)3.

The disodium hydrogen phosphate (DSP) and hydroxyapatite (HAP) were added into arsenic contaminated soil, then rice pot experiment was conducted to study the effects of phosphorus (P)-containing substances on arsenic (As) uptake by rice. The results showed that: DSP and HAP significantly increased soil pH and the contents of available P in soil (P < 0.05), activating soil arsenic. And DSP was stronger than HAP in improving the migration ability of As in soil. DSP and HAP treatments both significantly reduced the contents of total As in root, as well as total As and inorganic As in brown rice. But HAP significantly increased total As contents in stem. DSP and HAP treatments had better reducing effects on inorganic As than on total As in brown rice. And DSP had the same reducing effects as HAP on total As and inorganic As in brown rice. Analysis results showed that the contents of As in rice were affected by the antagonism between P and As and the increase of As bio-availability in soil. The antagonism played the major role in this study and it was clearly exhibited in both root and rice. Lower dosage (< or = 0.12 g x kg(-1)) of DSP and HAP increased total biomass of rice and brown rice yield, but with the increase of P addition, the two kinds of P-containing substances obviously inhibited the growth of rice, and inhibition by HAP was relatively light.
