Xinnaotongluo liquid protects H9c2 cells from H/R-induced damage by regulating MDM2/STEAP3

by Jiankun Cui, Qinwen Wang, Minghao Li

Xinnaotongluo liquid has been used to improve the clinical symptoms of patients with myocardial infarction. However, the molecular mechanism of Xinnaotongluo liquid is not completely understood. H9c2 cells exposed to hypoxia/reoxygenation (H/R) was used to simulate damage to cardiomyocytes in myocardial infarction in vitro. The biological indicators of H9c2 cells were measured by cell counting kit-8, enzyme linked immunoabsorbent assay, and western blot assay. In H/R-induced H9c2 cells, a markedly reduced murine double minute 2 (MDM2) was observed. However, the addition of Xinnaotongluo liquid increased MDM2 expression in H/R-induced H9c2 cells. And MDM2 overexpression strengthened the beneficial effects of Xinnaotongluo liquid on H9c2 cells from the perspective of alleviating oxidative damage, cellular inflammation, apoptosis and ferroptosis of H/R-induced H9c2 cells. Moreover, MDM2 overexpression reduced the protein expression of p53 and Six-Transmembrane Epithelial Antigen of Prostate 3 (STEAP3). Whereas, STEAP3 overexpression hindered the function of MDM2-overexpression in H/R-induced H9c2 cells. Our results insinuated that Xinnaotongluo liquid could protect H9c2 cells from H/R-induced damage by regulating MDM2/STEAP3, which provide a potential theoretical basis for further explaining the working mechanism of Xinnaotongluo liquid.

Comparative efficacy of non‐pharmacological interventions on sleep quality in old adults: A systematic review and network meta‐analysis

Abstract

Aims and Objectives

To compare the effectiveness of non-pharmacological interventions in enhancing sleep quality in older people.

Background

Sleep problems in older adults have become increasingly prominent. Sleep problems not only affect the health and quality of life of older people, but also the range of chronic diseases caused by sleep problems also impose a huge burden on social services and health care. Non-pharmacological interventions are an effective alternative to pharmacological therapies, but it is unclear which non-pharmacological therapies are most effective in enhancing sleep quality in older adults.

Design

A systematic review and network meta-analysis based on PRISMA-NMA.

Methods

A total of seven databases were searched from the establishment of the database to March 2023. After literature screening and data extraction, the Cochrane Bias assessment tool 2.0 version of randomised controlled trials (RCTs) was used to evaluate literature quality. A network meta-analysis was performed to evaluate the relative efficacy of the non-pharmacological interventions on sleep quality.

Results

A total of 71 RCTs involving nine non-pharmacological interventions were included. The results of the network meta-analysis showed that the joint intervention may be the most effective non-pharmacological intervention to enhance sleep quality in older adults.

Conclusion

This study confirms that non-pharmacological interventions can improve sleep quality in older adults. The use of non-pharmacological interventions can be promoted by healthcare professionals in the future to improve the quality of sleep and thus the physical and mental health of older people.

Relevance to Clinical Practice

This evidence suggests that joint interventions may be most effective. Therefore, in the future, a combination of non-pharmacological interventions could be used to maximise their effectiveness in improving sleep quality in older people and promoting healthy aging.

The efficacy of sacral foam dressing in preventing sacral pressure injury: A systematic review and meta‐analysis

Abstract

Purpose

We aim to evaluate the efficacy of sacral foam dressings in preventing sacral pressure injury.

Methods

The PubMed, Embase and Web of Science databases were searched for relevant publications until October 2023. All studies evaluating the efficacy of sacral foam dressings in preventing sacral pressure injury were included. We calculated pooled risk ratio (RR) with 95% confidence intervals (CIs) for binary outcomes. The Cochrane's Risk of Bias Tool were used to evaluate the quality of studies.

Results

A total of 9 randomized controlled studies with 3972 patients were included in this analysis. Sacral pressure injury rate was significantly lower in the sacral foam dressing group compared with the standard care group (RR: 0.37, 95% CI: 0.17–0.82). Furthermore, the rate of ≥stage II sacral pressure injury was also significantly reduced (RR: 0.56, 95% CI: 0.37–0.83), along with a lower blanching erythema rate (RR: 0.64, 95% CI: 0.42–0.97). No obvious publication bias was observed in the funnel plot (Egger's p values = 0.91).

Conclusions

Sacral foam dressing significantly reduced the incidence of sacral pressure injuries, including those of stage II or higher, and blanching erythema when compared to standard care without sacral foam dressing. However, the results should be interpreted with cautious because of the observed heterogeneity and the diverse patient population. Further larger, well-designed randomized control studies are needed.

Associations of serum DNA methylation levels of chemokine signaling pathway genes with mild cognitive impairment (MCI) and Alzheimer’s disease (AD)

by Ting Zou, Xiaohui Zhou, Qinwen Wang, Yongjie Zhao, Meisheng Zhu, Lei Zhang, Wei Chen, Pari Abuliz, Haijun Miao, Keyimu Kabinur, Kader Alimu

Objective

To investigate the associations of serum DNA methylation levels of chemokine signaling pathway genes with Alzheimer’s disease (AD) and mild cognitive impairment (MCI) in elderly people in Xinjiang, China, and to screen out genes whose DNA methylation could distinguish AD and MCI.

Materials and methods

37 AD, 40 MCI and 80 controls were included in the present study. DNA methylation assay was done using quantitative methylation-specific polymerase chain reaction (qMSP). Genotyping was done using Sanger sequencing.

Results

DNA methylation levels of ADCY2, MAP2K1 and AKT1 were significantly different among AD, MCI and controls. In the comparisons of each two groups, AKT1 and MAP2K1’s methylation was both significantly different between AD and MCI (p MAP2K1’s methylation was also significantly different between MCI and controls. Therefore, AKT1’s methylation was considered as the candidate serum marker to distinguish AD from MCI, and its association with AD was independent of APOE ε4 allele (p AKT1 hypermethylation was an independent risk factor for AD and MAP2K1 hypomethylation was an independent risk factor for MCI in logistic regression analysis (p Conclusion

This study found that the serum of AKT1 hypermethylation is related to AD independently of APOE ε4, which was differentially expressed in the Entorhinal Cortex of the brain and was an independent risk factor for AD. It could be used as one of the candidate serum markers to distinguish AD and MCI. Serum of MAP2K1 hypomethylation is an independent risk factor for MCI.

Comprehensive analysis of risk factors for surgical site infections following thoracoscopic radical resection in patients with lung cancer

Abstract

Surgical site infections (SSIs) post-thoracoscopic radical resection in lung cancer patients pose significant clinical challenges. This study aims to comprehensively identify the independent risk factors that influence the occurrence of SSIs following thoracoscopic radical resection for lung cancer. The study employed a retrospective analysis of 130 patients who underwent thoracoscopic radical resection for lung cancer. Inclusion and exclusion criteria were clearly defined, and ethical approvals were obtained. Patients were monitored for SSIs via clinical and biochemical markers, with data comprehensively gathered from electronic health records. Statistical analysis was rigorously conducted using SPSS v27.0, with methodologies including t-tests, Chi-square tests and logistic regression. The study aimed to identify independent risk factors for SSIs and incorporated a multidimensional assessment approach to provide robust, clinically relevant findings. Univariate analysis revealed surgical duration ≥3 h, non-usage of antibiotics, presence of diabetes and elevated levels of C-reactive protein (CRP) and procalcitonin (PCT) as significant correlates for SSIs. Multivariate analysis substantiated these factors as independent risk variables: surgery duration (odds ratio [OR] = 9.698, p < 0.05), presence of diabetes (OR = 6.89, p < 0.05), elevated CRP (OR = 7.306, p < 0.05) and elevated PCT (OR = 6.838, p < 0.05). Conversely, antibiotic administration served as a protective factor (OR = 0.572, p < 0.05). Surgical duration of 3 h or more, diabetes and elevated levels of CRP and PCT significantly heighten the risk for SSIs after thoracoscopic radical resection in lung cancer patients. Perioperative antibiotic administration acts as a protective factor. Clinicians should implement tailored preventative strategies to mitigate these identified risks.

Rehabilitation effects of game therapy in people living with dementia: A systematic review and meta‐analysis

Abstract

Background

As a devastating neurodegenerative disease, Alzheimer's disease (AD) imposes a considerable direct and indirect financial burden. However, effective drug treatment options are limited. In recent years, game therapy has become a research hotspot in this field.

Aims

The purpose of this study was to synthesize the conclusions of existing studies and integrate the data to evaluate the effects of game therapy on people living with dementia (PLWD).

Methods

We included randomized clinical trials and quasi-experimental studies which assessed the impacts of game therapy on PLWD and took cognitive function, quality of life, and depression as outcome indicators. Two trained researchers independently screened the studies, evaluated the quality, and extracted the data. Statistical analysis was performed by Review Manager (Revman) 5.3 and STATA16.0 software.

Results

There were 12 studies involving 877 PLWD included, total. The results of the meta-analysis demonstrated that the Mini-Mental State Examination (MMSE) scores of the test group were significantly higher than that of the control group (SMD = 2.69, 95% CI [1.88, 3.51], p < .01), and the Cornell Scale for Depression in Dementia scores of the test group were significantly lower than those of the control group (SMD = −4.28, 95% CI [−6.96, −1.60], p < .01); but in terms of quality of life (SMD = 0.17, 95% CI [−0.82, 1.16], p = .74), the difference was not statistically significant.

Linking Evidence to Action

Game therapy can improve cognitive function and depression in PLWD. The combination of different types of games can improve the different clinical symptoms of PLWD, and different intervention time also have different effects on the outcome, which shows that we can develop unique, systematic, safe, and scientific game intervention programs for PLWD to improve their cognitive function and depression.
