Dose-response relationships between body-mass index and pressure injuries occurrence in hospitalized patients: A multi-center prospective study.

BACKGROUND: Pressure injuries (PIs) are one of the leading potentially preventable hospital-acquired complications associated with prolonged hospital length, poor quality of life and financial burden. The relationship between body mass index (BMI) and PIs occurrence is controversial. OBJECTIVE: The aim of this study was to further examine relationships between BMI and PIs occurrence in hospitalized patients. DESIGN: A multi-center prospective study. SETTING: 39 hospitals located in northwest China from April 2021 to July 2023. PARTICIPANTS: 175,960 hospitalized patients aged over 18 years were enrolled, and 170,800 patients were included in the final analysis. METHODS: BMI and clinical characteristics were assessed at baseline. PIs assessment were performed by trained nurses, with data recorded for the presence, the location and stage of each PI. For staging PIs, the National Pressure Ulcer Advisory Panel（NPUAP） staging system were used. The multivariate logistic regressions analysis and restricted cubic splines (RCS) models were used to explore associations between BMI and PIs, adjusting for potential confounders. RESULTS: Of 175,960 participants, 5160 were excluded from analyses. The multivariate logistic regression model identified a positive relationship between under-weight BMI and risk of PIs occurrence (OR = 1.60, 95% CI:1.18-2.17). We also found U shaped association between BMI and PIs occurrence (non-linear P < 0.001). BMI less than 23 kg/m2 significantly increased risk of PIs, and there was a tendency to increase risk of PIs at BMI higher than 30 kg/m2. We stratified participants by sex to further investigate their association and found the risk of PIs increases substantially in women at BMI below 17 kg/m2 and in men at BMI below 23 kg/m2. CONCLUSIONS: The present study indicated that there was an approximate U shaped relationship between BMI and PIs occurrence, and this association was potentially different between men and women.

Different Levels of Autophagy Activity in Mesenchymal Stem Cells Are Involved in the Progression of Idiopathic Pulmonary Fibrosis.

Idiopathic pulmonary fibrosis (IPF) is an age-related lung interstitial disease that occurs predominantly in people over 65 years of age and for which there is a lack of effective therapeutic agents. It has demonstrated that mesenchymal stem cells (MSCs) including alveolar epithelial cells (AECs) can perform repair functions. However, MSCs lose their repair functions due to their distinctive aging characteristics, eventually leading to the progression of IPF. Recent breakthroughs have revealed that the degree of autophagic activity influences the renewal and aging of MSCs and determines the prognosis of IPF. Autophagy is a lysosome-dependent pathway that mediates the degradation and recycling of intracellular material and is an efficient way to renew the nonnuclear (cytoplasmic) part of eukaryotic cells, which is essential for maintaining cellular homeostasis and is a potential target for regulating MSCs function. Therefore, this review focuses on the changes in autophagic activity of MSCs, clarifies the relationship between autophagy and health status of MSCs and the effect of autophagic activity on MSCs senescence and IPF, providing a theoretical basis for promoting the clinical application of MSCs.

Comparison of the predictive validity of the Braden and Waterlow scales in intensive care unit patients: A multicentre study.

BACKGROUND: The first step in preventing pressure injuries (PIs), which represent a significant burden on intensive care unit (ICU) patients and the health care system, is to assess the risk for developing PIs. A valid risk assessment scale is essential to evaluate the risk and avoid PIs. OBJECTIVES: To compare the predictive validity of the Braden scale and Waterlow scale in ICUs. DESIGN: A multicentre, prospective and cross-sectional study. METHODS: We conducted this study among 6416 patients admitted to ICUs in Gansu province of China from April 2021 to October 2022. The incidence and characteristics of PIs were collected. The risk assessment of PIs was determined using the Braden and Waterlow scale. The sensitivity, specificity, positive and negative predictive values, and the area under the receiver operating characteristic curve of the two scales were compared. RESULTS: Out of 5903 patients, 72 (1.2%) developed PIs. The sensitivity, specificity, positive and negative predictive, and the area under the curve of the Braden scale were 77.8%, 50.9%, 0.014 and 0.996, and 0.689, respectively. These values for the Waterlow scale were 54.2%, 71.1%, 0.017, 0.994 and 0.651. CONCLUSIONS: Both scales could be used for risk assessment of PIs in ICU patients. However, the accuracy of visual inspection for assessment of skin colour, nursing preventive measures for patients and scales inter-rater inconsistency may limited the predictive validity statistics. RELEVANCE TO CLINICAL PRACTICE: Both scales could be used for PIs risk assessment. The low specificity of the Braden scale and low sensitivity of the Waterlow scale remind medical staff to use them in combination with clinical judgement and other objective indicators. PATIENT OR PUBLIC CONTRIBUTION: This study was designed to enhance the management of PIs. Patients and the general public were not involved in the study design, analysis, and interpretation of the data or manuscript preparation.

The potential role of ferroptosis in the physiopathology of deep tissue injuries.

Deep tissue injuries (DTIs) are a serious type of pressure injuries that mainly occur at the bony prominences and can develop rapidly, making prevention and treatment more difficult. Although consistent research efforts have been made over the years, the cellular and molecular mechanisms contributing to the development of DTIs remain unclear. More recently, ferroptosis, a novel regulatory cell death (RCD) type, has been identified that is morphological, biochemical and genetic criteria distinct from apoptosis, autophagy and other known cell death pathways. Ferroptosis is characterized by iron overload, iron-dependent lipid peroxidation and shrunken mitochondria. We also note that some of the pathological features of DTI are known to be key features of the ferroptosis pathway. Numerous studies have confirmed that ferroptosis may be involved in chronic wounds, including DTIs. Here, we elaborate on the basic pathological features of ferroptosis. We also present the evidence that ferroptosis is involved in the pathology of DTIs and highlight a future perspective on this emerging field, desiring to provide more possibilities for the prevention and treatment of DTIs.

Unveiling the veil of lactate in tumor-associated macrophages: a successful strategy for immunometabolic therapy.

Lactate, traditionally regarded as a metabolic waste product at the terminal of the glycolysis process, has recently been found to have multifaceted functional roles in metabolism and beyond. A metabolic reprogramming phenomenon commonly seen in tumor cells, known as the "Warburg effect," sees high levels of aerobic glycolysis result in an excessive production of lactate. This lactate serves as a substrate that sustains not only the survival of cancer cells but also immune cells. However, it also inhibits the function of tumor-associated macrophages (TAMs), a group of innate immune cells ubiquitously present in solid tumors, thereby facilitating the immune evasion of malignant tumor cells. Characterized by their high plasticity, TAMs are generally divided into the pro-inflammatory M1 phenotype and the pro-tumour M2 phenotype. Through a process of 'education' by lactate, TAMs tend to adopt an immunosuppressive phenotype and collaborate with tumor cells to promote angiogenesis. Additionally, there is growing evidence linking metabolic reprogramming with epigenetic modifications, suggesting the participation of histone modification in diverse cellular events within the tumor microenvironment (TME). In this review, we delve into recent discoveries concerning lactate metabolism in tumors, with a particular focus on the impact of lactate on the function of TAMs. We aim to consolidate the molecular mechanisms underlying lactate-induced TAM polarization and angiogenesis and explore the lactate-mediated crosstalk between TAMs and tumor cells. Finally, we also touch upon the latest progress in immunometabolic therapies and drug delivery strategies targeting glycolysis and lactate production, offering new perspectives for future therapeutic approaches.

Machine learning-based prediction models for pressure injury: A systematic review and meta-analysis.

Despite the fact that machine learning (ML) algorithms to construct predictive models for pressure injury development are widely reported, the performance of the model remains unknown. The goal of the review was to systematically appraise the performance of ML models in predicting pressure injury. PubMed, Embase, Cochrane Library, Web of Science, CINAHL, Grey literature and other databases were systematically searched. Original journal papers were included which met the inclusion criteria. The methodological quality was assessed independently by two reviewers using the Prediction Model Risk of Bias Assessment Tool (PROBAST). Meta-analysis was performed with Metadisc software, with the area under the receiver operating characteristic curve, sensitivity and specificity as effect measures. Chi-squared and I2 tests were used to assess the heterogeneity. A total of 18 studies were included for the narrative review, and 14 of them were eligible for meta-analysis. The models achieved excellent pooled AUC of 0.94, sensitivity of 0.79 (95% CI [0.78-0.80]) and specificity of 0.87 (95% CI [0.88-0.87]). Meta-regressions did not provide evidence that model performance varied by data or model types. The present findings indicate that ML models show an outstanding performance in predicting pressure injury. However, good-quality studies should be conducted to verify our results and confirm the clinical value of ML in pressure injury development.

Unlocking the potential of Mesenchymal stem cells in liver Fibrosis: Insights into the impact of autophagy and aging.

Liver fibrosis is a chronic liver disease characterized by extracellular matrix protein accumulation, potentially leading to cirrhosis or hepatocellular carcinoma. Liver cell damage, inflammatory responses, and apoptosis due to various reasons induce liver fibrosis. Although several treatments, such as antiviral drugs and immunosuppressive therapies, are available for liver fibrosis, they only provide limited efficacy. Mesenchymal stem cells (MSCs) have become a promising therapeutic option for liver fibrosis, because they can modulate the immune response, promote liver regeneration, and inhibit the activation of hepatic stellate cells that contribute to disease development. Recent studies have suggested that the mechanisms through which MSCs gain their antifibrotic properties involve autophagy and senescence. Autophagy, a vital cellular self-degradation process, is critical for maintaining homeostasis and protecting against nutritional, metabolic, and infection-mediated stress. The therapeutic effects of MSCs depend on appropriate autophagy levels, which can improve the fibrotic process. Nonetheless, aging-related autophagic damage is associated with a decline in MSC number and function, which play a crucial role in liver fibrosis development. This review summarizes the recent advancements in the understanding of autophagy and senescence in MSC-based liver fibrosis treatment, presenting the key findings from relevant studies.

Association of adverse childhood experiences and depression among medical students: the role of family functioning and insomnia.

Background: Few studies have explored the mechanisms linking adverse childhood experiences (ACEs) to depression in medical students. This study aimed to investigate the relationship between ACEs and depression through the serial mediation effect of family functioning and insomnia. Methods: A cross-sectional survey was conducted with 368 medical students from university in Chengdu in 2021. The participants were asked to complete four self-report questionnaires, including ACEs scale, the family APGAR index, the ISI and PHQ-9. Singe and serial mediation analyses were conducted using structural equation modeling by Mplus 8.3. Results: ACEs had a significant direct effect on depression (ß = 0.438, p < 0.001) and through three significantly indirect pathways: (1) through family functioning (ß = 0.026, 95% CI: 0.007-0.060), accounting for 5.9% of the total effect; (2) through insomnia (ß = 0.103, 95% CI: 0.011-0.187), accounting for 23.5% of the total effect; and (3) through the serial mediators involving in family functioning and insomnia (ß = 0.038, 95% CI: 0.015-0.078), accounting for 8.7% of the total effect. The total indirect effect was 38.1%. Limitations: This cross-sectional study prevented us from establishing causality. Conclusion: This study highlights the role of family functioning and insomnia as serial mediators of the relationship between ACEs and depression. Findings help to elucidate the mechanism that underlines the pathway between ACEs and depression in medical students. These findings may indicate developing measures to strengthen family functioning and improve insomnia aiming to reduce depression in medical students with ACEs.

The prevalence and characteristics of alexithymia in patients with type 2 diabetes mellitus: A systematic review and meta-analysis.

BACKGROUND: Alexithymia is common in patients with type 2 diabetes mellitus (T2DM). Although the estimated prevalence of alexithymia in patients with T2DM is widely reported, these results have not been synthesized. AIM: To systematically assess the prevalence and characteristics of alexithymia in patients with T2DM. METHODS: We searched for relevant publications in PubMed, Embase, Web of Science, China Knowledge Resource Integrated Database, Wanfang Database, Chinese Biomedical Database, and Weipu Database. The prevalence of alexithymia, the mean scores, and standard deviations of the total scale of the 20-item Toronto Alexithymia Scale (TAS-20) were pooled using random effects meta-analysis in Stata 13.0, with studies stratified by study location in this meta-analysis. RESULTS: This meta-analysis included thirteen articles. Pooled prevalence of alexithymia (TAS-20 total scores ≥61) were 43.0% (95%CI 35.0-51.0%), and the prevalence of alexithymia was higher in China (45.0%, 95%CI 36.0-54.0%) compared with non-China (41.0%, 95%CI 29.0-54.0%). The pooled mean score for the TAS-20 total scale was 57.70 (95% CI 55.25-60.15). Leave-one-out analysis showed that none of the studies significantly impacted the overall pooled results. CONCLUSIONS: This meta-analysis indicated a high prevalence of alexithymia in patients with T2DM. Thus, clinicians need to be aware of and assess appropriately for alexithymia in patients with T2DM.

A Deep Insight Into Regulatory T Cell Metabolism in Renal Disease: Facts and Perspectives.

Kidney disease encompasses a complex set of diseases that can aggravate or start systemic pathophysiological processes through their complex metabolic mechanisms and effects on body homoeostasis. The prevalence of kidney disease has increased dramatically over the last two decades. CD4+CD25+ regulatory T (Treg) cells that express the transcription factor forkhead box protein 3 (Foxp3) are critical for maintaining immune homeostasis and preventing autoimmune disease and tissue damage caused by excessive or unnecessary immune activation, including autoimmune kidney diseases. Recent studies have highlighted the critical role of metabolic reprogramming in controlling the plasticity, stability, and function of Treg cells. They are also likely to play a vital role in limiting kidney transplant rejection and potentially promoting transplant tolerance. Metabolic pathways, such as mitochondrial function, glycolysis, lipid synthesis, glutaminolysis, and mammalian target of rapamycin (mTOR) activation, are involved in the development of renal diseases by modulating the function and proliferation of Treg cells. Targeting metabolic pathways to alter Treg cells can offer a promising method for renal disease therapy. In this review, we provide a new perspective on the role of Treg cell metabolism in renal diseases by presenting the renal microenvironment、relevant metabolites of Treg cell metabolism, and the role of Treg cell metabolism in various kidney diseases.

Frailty is associated with 90-day unplanned readmissions and death in patients with heart failure: A longitudinal study in China.

BACKGROUND: Frailty has been reported to be significantly associated with adverse health outcomes in people with heart failure (HF). OBJECTIVES: To explore the potential effects of frailty on unplanned readmissions and death in people with HF patients aged 18 years or older. METHODS: 342 HF patients aged 18 years or older from the heart centers of two different tertiary care hospitals located in northwest of China were enrolled between July and December 2020. Frailty was assessed by the Tilburg Frailty Indicator. The patients were followed for unplanned readmissions, and all-cause mortality at 30, 60, as well as 90 days after discharge. Multivariate cox regression models were used to analyze the effects of frailty on 90-day unplanned readmission and death in the patients with HF. RESULTS: Frailty prevalence was 54.7% among 342 HF patients, with a mean age of 64.65 ± 11.90 years. It was found that compared to non-frailty HF patients, the frailty HF patients were older and displayed higher systolic blood pressure, longer duration of HF, more severe cognitive function, and more comorbidities (P < 0.05). On the contrary, the patients in the frail group had a higher incidence of unplanned readmission (73.1% vs. 26.9%, χ2 = 18.87, P < 0.01) and death (100% vs. 0%, χ2 = 6.94, P < 0.01) than those in the non-frail group. Multivariate cox regression analysis showed that frailty could serve as an independent risk factor for 90-day unplanned readmission (HR = 1.469, 95% CI 1.318-1.637, P < 0.01) and 90-day death (HR=2.270, 95% CI 1.091-4.726, P < 0.01) in the patients with HF. CONCLUSION: Frailty can act as an independent predictor of unplanned readmission and death 90-day after discharge in HF patients aged 18 years or older.

Effects of nurse-led web-based interventions on people with type 2 diabetes mellitus: A systematic review and meta-analysis.

INTRODUCTION: Diabetes mellitus is an expanding global health problem. Currently, the home management of diabetes is mainly led by a multidisciplinary team based on telemedicine. However, the role nurses play in it remains inconclusive. This study aimed to investigate the effectiveness of nurse-led web-based intervention on glycated haemoglobin, blood pressure and lipid profile in patients with type 2 diabetes. METHODS: An exhaustive systematic literature search was undertaken using the following databases: PubMed, Web of Science, Embase, The Cochrane Central Register of Controlled Trials and CINAHL. Two investigators independently extracted data and assessed the quality of the studies by examining the risk of bias and using Modified Jadad Score system. We conducted a meta-analysis of randomized controlled trials that had been published from inception to July 2020, using Review Manager 5.3. RESULTS: Eleven randomized controlled trials were selected that included 2063 participants. Meta-analyses results indicated significant effects on not only glycated haemoglobin (pooled mean difference (MD) = -0.40, 95% confidence interval (CI): -0.5 to -0.26, p < 0.00001), but also on systolic blood pressure (pooled MD = -1.91, 95% CI: -3.73 to -0.09, p = 0.04) and low density lipoprotein (pooled standardized MD = -0.29, 95% CI: -0.44 to -0.15, p < 0.0001). There were no effects of nurse-led web-based intervention on fasting blood glucose, diastolic blood pressure, high density lipoprotein, body mass index and triglycerides. DISCUSSION: Nurse-led web-based intervention is a promising way to complement routine clinical care. However, the specific intervention content and intervention media still need to carry out large-scale well-designed randomized controlled trials. Systematic review registration: PROSPERO CRD 42020204565.

Impacts of frailty on health care costs among community-dwelling older adults: A meta-analysis of cohort studies.

BACKGROUND: The demands for health care services from the frail elderly individuals in the community continue to increase, which will exert a tremendous burden on health care costs. However, little is known regarding the magnitude of these impacts. In this study, we performed a systematic review and meta-analysis of the evidence to explore the impact of frailty on health care costs among community-dwelling older adults. MATERIALS AND METHODS: Relevant published articles were searched from PubMed, Embase, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Journal Full-text Database (VIP), Wanfang Database, Chinese Biomedical Literature Database (CBM), and the reference lists of articles. Published cohort or cross-sectional studies assessing the impacts of frailty on health care costs among community-dwelling older adults were identified (to June 2020). The outcomes on health care costs before and after baseline were stratified by frailty status. RESULTS: A total of 7 cohort studies comprised of a total of 3,750,611 participants were included in our study. Our analyses showed that: (1) compared with the robust group, health care costs increased by $79-13,423.83 (standardized mean difference, SMD = 0.22, 95% Confidence interval, 95% CI, 0.22-0.22; P < 0.00001) in the pre-frail elderly and by $616-32,549.96 (SMD = 0.55, 95% CI, 0.44-0.67; P < 0.00001) in the frail elderly in the community. A significantly higher in the increase of health care costs was observed in the frail group compared with the pre-frail group(SMD = 0.35, 95% CI, 0.19-0.51; P < 0.0001); (2) the frailty phenotype components increased the health care costs of the elderly in community (weight loss: $1,630-6,209, SMD = 0.43, 95% CI, 0.17-0.69; P = 0.001; weakness: $275-7,586, SMD = 0.24, 95% CI, 0.08-0.40; P = 0.001; exhaustion: $1,545-10,559, SMD = 0.31, 95% CI, 0.13-0.49; P = 0.0006; slowness: $352-1,1891, SMD = 0.40, 95% CI = 0.14-0.65; P = 0.003; low physical activity: $512-3,459, SMD = 0.26, 95% CI, 0.16-0.36; P < 0.00001); (3) the increase in the frailty index was parallel with the increase in health care costs by $12,363-21,066 (SMD = 0.41, 95% CI, 0.29-0.53; P < 0.00001). CONCLUSIONS AND IMPLICATIONS: This study revealed the adverse economic impacts of frailty status, frailty phenotype components, and frailty index on health care costs in community-dwelling older adults. Future research is warranted to investigate costs incurred by interventions to improve frailty, which will provide further insights into additional health care costs due to frailty.

Menopause and frailty: a scoping review.

IMPORTANCE AND OBJECTIVE: Frailty refers to the decline in physiological reserve capacity caused by the deterioration of multiple physiological systems (brain, endocrine system, immune system, and skeletal muscle), leading to increased vulnerability and decreased stress capacity. Women have a higher prevalence of frailty than men, although the epidemiological factors underlying this phenomenon are not fully understood. Menopause and menopause-related characteristics may be among the contributing factors. Hence, the purpose of this scoping review was to explore the relationship between menopause and frailty. We attempted to summarize information such as the age that menopause occurs, years since menopause, types of menopause, and hormones and inflammatory markers of frailty among postmenopausal women. METHODS: PubMed, EMBASE, The Cochrane Library, the Cumulative Index to Nursing and Allied Health Literature and Web of Science, the China National Knowledge Infrastructure, the China Biomedical Literature Service System, Wanfang Database and the WeiPu (VIP) Database were searched from inception until April 3, 2019. Supplementary searches of the references, cited documents, and similar documents of the included literature were also carried out. DISCUSSION AND CONCLUSIONS: Of 762 papers identified, 15 articles matching the criteria were included. The prevalence of frailty among postmenopausal women ranged from 5.9% to 57.3%. Existing studies suggest that menopause is associated with frailty. Early menopause, hysterectomy, low-free testosterone levels, and high C-reactive protein levels may increase the likelihood of frailty among postmenopausal women. Few original studies have explored the relationship between estrogen and frailty and the results of these studies are conflicting. Changes in hormone and inflammatory cytokine levels may mediate frailty among postmenopausal women. More in-depth research would be required to better understand the physiological and etiological mechanisms of the occurrence of frailty among postmenopausal women.

Research on the formation of humanistic care ability in nursing students: A structural equation approach.

OBJECTIVE: To construct and test a hypothetical model linking the caring ability of nursing students with empathy ability, emotional intelligence, and communication ability. METHOD: Participants were 851 students from three undergraduate colleges and one junior college in China, Gansu Province. Participating students had to fulfill the following requirements: different levels of nursing majors (undergraduates or junior college students), understand the study purpose, and be willing to participate in this study. Exclusion: secondary college students. Variables were measured by the Caring Ability Inventory, Emotional Intelligence Scale, Supportive Communicative Scale, and Interpersonal Reactivity Index. Data were analyzed with structural equation modeling to explore the path relationships and mutual effects between structural elements. RESULTS: Empathy (ß = 0.25, P<0.001), emotional intelligence (ß = 0.36, P<0.001), and communication ability (ß = 0.28, P<0.001) were significantly associated with the caring ability of nursing students. Empathy was the strongest factor associated with caring ability and emotional intelligence was a partial mediator of the relationship between empathy and communication skills. CONCLUSIONS: The nurse's humanistic care ability requires continuous learning and school education. To enhance the humanistic care ability of nursing students, nursing educators should develop target strategies to improve the 'sympathetic ability,' 'emotional intelligence' and 'communication ability' of nursing students.

Trehalose 6-phosphate signal is closely related to sorbitol in apple (Malus domestica Borkh. cv. Gala).

Trehalose-6-phosphate (Tre6P) is a precursor of trehalose, which is widespread in nature and greatly influences plant growth and development. Tre6P acts as a signal of carbon availability in many plants, but little is known about the function of Tre6P in rosaceous plants, which have specific sorbitol biosynthesis and transportation pathways. In the present study, Tre6P levels and Sorbitol:Tre6P ratios were analyzed in apple (Malus domestica, Borkh. cv. Gala). Tre6P levels were positively correlated with sorbitol content but negatively correlated with sucrose, glucose, and fructose content in developing fruit. However, under sorbitol-limited conditions, Tre6P levels were positively correlated with both sorbitol and sucrose. In the presence of different exogenous sugar supply, Tre6P levels increased corresponding with sorbitol, but this was not the case with sucrose. In addition, Tre6P content and sorbitol:Tre6P ratios were more highly correlated with ADP-glucose levels under sorbitol-limited conditions and fruit development stages, respectively. These results suggest that Tre6P is more closely related to sorbitol than other soluble sugars and has an important role in influencing carbon metabolism in apple.

Dynamic transcription profiles of "Qinguan" apple (Malus × domestica) leaves in response to Marssonina coronaria inoculation.

Marssonina apple blotch, caused by the fungus Marssonina coronaria, is one of the most destructive apple diseases in China and East Asia. A better understanding of the plant's response to fungi during pathogenesis is urgently needed to improve plant resistance and to breed resistant cultivars. To address this, the transcriptomes of "Qinguan" (a cultivar with high resistance to M. coronaria) apple leaves were sequenced at 12, 24, 48, and 72 h post-inoculation (hpi) with Marssonina coronaria. The comparative results showed that a total of 1956 genes were differentially expressed between the inoculated and control samples at the 4 time points. Gene ontology (GO) term enrichment analysis of differentially expressed genes (DEGs) revealed changes in cellular component, secondary metabolism including chalcone isomerase activity, phytoalexin biosynthetic process, anthocyanin-containing compound biosynthetic process, lignin biosynthetic process, positive regulation of flavonoid biosynthetic process; and molecular functions or biological processes related to the defense response, biotic stimulus response, wounding response and fungus response. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that DEGs were significantly enriched in flavonoid biosynthesis, vitamin B6 metabolism, phenylpropanoid biosynthesis, and the stilbenoid, diarylheptanoid and gingerol biosynthesis pathways. Furthermore, the importance of changes in cellular components and partial polyphenol compounds when encountering M. coronaria are discussed.
