Arenobufagin modulation of PCSK9-mediated cholesterol metabolism induces tumor-associated macrophages polarisation to inhibit hepatocellular carcinoma progression.

BACKGROUND: The tumor microenvironment (TME) of hepatocellular carcinoma is heterogeneous enough to be prone to drug resistance and multidrug resistance during treatment, and reprogramming of cholesterol metabolism in TME mediates tumor-associated macrophages (TAMs) polarization, which has an impact on the regulation of malignant tumor progression. Arenobufagin (ARBU) was extracted and isolated from toad venom (purity ≥98 %), which is the main active ingredient of the traditional Chinese medicine Chan'su with good anti-tumor effects. PURPOSE: To investigate the regulatory effect of ARBU on lipid metabolism in tumor microenvironment, interfere with macrophage polarization, and determine its mechanism of action on liver cancer progression. METHODS: In this study, the inhibitory effect of ARBU on the proliferation of Hepa1-6 in C57 mice and the safety of administration were evaluated by establishing a transplanted tumor model of Hepa1-6 hepatocellular carcinoma mice and using 5-FU as a positive control drug. In addition, we constructed a co-culture system of Hepa1-6 cells and primary mouse macrophages to study the effects of ARBU on the polarization phenotypic transformation of macrophages and the proliferation and migration of hepatoma cells. The influence of ARBU on the metabolism of lipids in the hepatocellular carcinoma mouse model was investigated by combining it with lipidomics technology. The influence of ARBU on the PCSK9/LDL-R signaling pathway and macrophage polarization, which regulate cholesterol metabolism, was tested by using qRT-PCR, gene editing, IF, and WB. CONCLUSION: ARBU significantly inhibited the proliferation of Hepa1-6 in vivo and in vitro, regulated cholesterol metabolism, and promoted the M1-type polarization of macrophages in the tumor microenvironment. ARBU inhibits cholesterol synthesis in the TME through the PCSK9/LDL-R signaling pathway, thereby blocking macrophage M2 polarization, promoting apoptosis of the tumor cells, and inhibiting their proliferation and migration.

Ferritin-mediated mitochondrial iron homeostasis is essential for the survival of hematopoietic stem cells and leukemic stem cells.

Iron metabolism plays a crucial role in cell viability, but its relationship with adult stem cells and cancer stem cells is not fully understood. The ferritin complex, responsible for intracellular iron storage, is important in this process. We report that conditional deletion of ferritin heavy chain 1 (Fth1) in the hematopoietic system reduced the number and repopulation capacity of hematopoietic stem cells (HSCs). These effects were associated with a decrease in cellular iron level, leading to impaired mitochondrial function and the initiation of apoptosis. Iron supplementation, antioxidant, and apoptosis inhibitors reversed the reduced cell viability of Fth1-deleted hematopoietic stem and progenitor cells (HSPCs). Importantly, leukemic stem cells (LSCs) derived from MLL-AF9-induced acute myeloid leukemia (AML) mice exhibited reduced Fth1 expression, rendering them more susceptible to apoptosis induced by the iron chelation compared to normal HSPCs. Modulating FTH1 expression using mono-methyl fumarate increased LSCs resistance to iron chelator-induced apoptosis. Additionally, iron supplementation, antioxidant, and apoptosis inhibitors protected LSCs from iron chelator-induced cell death. Fth1 deletion also extended the survival of AML mice. These findings unveil a novel mechanism by which ferritin-mediated iron homeostasis regulates the survival of both HSCs and LSCs, suggesting potential therapeutic strategies for blood cancer with iron dysregulation.

Cinobufacini injection delays hepatocellular carcinoma progression by regulating lipid metabolism via SREBP1 signaling pathway and affecting macrophage polarization.

ETHNOPHARMACOLOGICAL RELEVANCE: Cinobufacini injection, an aqueous extract of the toad, is a commonly used anti-tumor animal herbal medicine in clinical practice. It has the effects of detoxifying, reducing swelling, and relieving pain. AIMS OF THE STUDY: To investigate the effects of Cinobufacini injection on hepatocellular carcinoma progression by regulating lipid metabolism and macrophage polarization in the tumor microenvironment and to identify the potential molecular mechanisms. MATERIALS AND METHODS: To establish the axillary transplantation tumor model of hepatocellular carcinoma Hepa1-6 in C57BL/6 mice, and to evaluate the inhibitory effect of Cinobufacini injection on hepatocellular carcinoma in vivo as well as drug delivery security. Combined metabolomics and transcriptomics analysis of the effect of Cinobufagin Injection on tumor microenvironment. An in vitro mouse co-culture model of peritoneal macrophages and Hepa1-6 cells was established to research the effects of Cinobufacini injection on macrophage polarization, hepatocellular carcinoma cell growth, migration, and changes in lipid metabolism. Cinobufacini injection inhibition of the AMPK/SREBP1/FASN signaling pathway regulating cholesterol metabolism and affecting macrophage polarization was examined using qRT-PCR, lentiviral transfection, immunofluorescence, and Western blot. RESULT: In vivo experiments demonstrated that Cinobufacini injection treatment significantly inhibited the growth of Hepa1-6 hepatomas, along with a reduction in cholesterol content and a decrease in the percentage of M2 macrophages in tumor tissue. In vitro, we found that Cinobufacini injection inhibits IL-4-induced M2 macrophage polarization, reduces the cholesterol content of Hepa1-6 cells in a co-culture system, and inhibits the promotion of hepatocellular carcinoma cells by M2 macrophages. In addition, successful overexpression of SREBP1 in Hepa1-6 cells showed more pronounced cellular activity whereas Cinobufacini injection inhibited this change and reduced intracellular lipid levels. CONCLUSION: Cinobufacini injection inhibits cholesterol synthesis within the tumor microenvironment via the AMPK/SERBP1/FASN signaling pathway, which in turn blocks the M2 polarization of macrophages, leading to the weakening of hepatocellular carcinoma growth and migration, and the promotion of its apoptosis. Our findings provide an important Introduction to understanding the molecular mechanism of Cinobufacini injection's anticancer activity and provide reliable theoretical and experimental support for its clinical application.

Paris polyphylla saponins II inhibits invasive, migration and epithelial-mesenchymal transition of melanoma cells through activation of autophagy.

Malignant melanoma is a kind of malignant tumor derived from normal epidermal melanocytes or original nevus cells. It has a high degree of malignancy, rapid progress, dangerous condition, and poor prognosis. In recent years, the innovation of traditional Chinese medicine has broadened the scope and effect of tumor treatment. It is a hotspot and breakthrough to find new anti-tumor invasion and migration drugs from natural plants or traditional Chinese medicine. This study explored the role of PPII in promoting autophagy to inhibit EMT of melanoma cells, the role of the PI3K/Akt signaling pathway in the invasion and migration of melanoma cells induced by PPII. We found that PPII effectively inhibited the proliferation, invasion and migration of melanoma B16 and B16F10 in vitro, and induced autophagy. We also established the xenograft tumor and metastatic tumor model of C57BL/6 mice with B16F10 cells. Results showed that PPII effectively inhibited the growth of transplanted tumors, induced autophagy and inhibited the expression level of EMT related protein; Metastasis experiment showed that PPII inhibited the invasion and migration of B16F10, the effect of inhibiting lung metastasis is the most significant. Further mechanism studies showed that the inhibition of PPII on melanoma invasion and migration is related to its induction of autophagy and then inhibition of EMT.

A UPLC-QTOF/MS-based hepatic tissue metabolomics approach deciphers the mechanism of Huachansu tablets-based intervention against hepatocellular carcinoma.

Huachansu (HCS) tablets, classified as well-known traditional Chinese medicine (TCM) preparation, have been proved to be effective in the treatment of hepatocellular carcinoma (HCC) in clinical studies. However, the underlying mechanism of HCS tablets against HCC has not been comprehensively elucidated. In this study, a rat model of HCC was established with diethylnitrosamine (DEN) inducer. The efficacy of HCS tablets against HCC was assessed through liver histopathological examination and evaluation of biochemical indicators. A metabolomics method based on UPLC-Q-TOF/MS combined with multivariate data analysis was established to identify differential metabolites related to the inhibition effect of HCS tablets on HCC, and then the relevant metabolic pathway analysis was performed to investigate the anti-HCC mechanisms of HCS tablets. The results showed that compared to the control group, the HCC model group showed a significant increase in the values of HCC-related biochemical indicators and the number of tumor nodules, indicating the successful establishment of the HCC rat model. Upon treatment with HCS tablets, the values of HCC-related biochemical indicators decreased, liver fibrosis and nuclear deformation were also significantly alleviated. A total of 15 differential metabolites associated with the anti-tumor effect of HCS tablets on HCC were screened and annotated through hepatic tissue metabolomics studies. Analysis of metabolic pathways revealed that the therapeutic effects of HCS tablets on HCC mainly involved the pentose and glucuronate interconversions and arachidonic acid metabolism. Further western blotting corroborated that the alteration in arachidonic acid (AA) level after the intervention of HCS tablets was related to the inhibition of cPLA2α expression in rat liver tissues. In conclusion, HCS tablets exhibit a certain anti-tumor effect on HCC, and the metabolomics method based on UPLC-Q-TOF/MS combined with further verification at the biochemical level is a promising way to reveal its underlying mechanism.

Bibliometric analysis of Traditional Chinese Medicine nanoparticles research from 2005 to 2023.

To gain a deeper understanding of the current status of research on Traditional Chinese Medicine (TCM) and nanoparticles, we conducted a bibliometric study. We conducted a literature search in the Web of Science (WOS) for publications related to TCM and nanoparticles from 1992 to 2023. The data, including countries of publication, research institutions, journals, citations, and keywords, were analyzed using the Bibliometrix R-4.0 software package. We performed an analysis to identify the co-occurrence of keywords in the documents including their titles and abstracts. From 2005 to 2023, a total of 309 publications were included, with an average annual growth rate of 4.25%. The majority of these publications were published in Q1 journals (72, 47.06%) and Q2 journals (45, 29.41%). Among the 309 publications, 22 articles (7.12%) had an impact factor greater than 10, while 78 articles (25.24%) had an impact factor greater than 5. The analysis of international collaboration networks revealed limited international cooperation, with most collaborations occurring between institutions in China, the United States, and Australia. These 309 publications involved a total of 438 research institutions, with Chinese research institutions being the most prolific contributors. In this study, a total of 309 publications were included, comprising 1142 author keywords and 1175 keywords plus. Factor analysis of the 1175 keywords plus revealed that they could be grouped into five categories: one category included terms such as "oxide" and "zinc," another category included terms like "lipid" and "acid," a third category included terms such as "improve" and "enhance," a fourth category included terms like "silica" and "mesoporous," and the fifth category included terms like "PLGA" and "immune." Research on nanoparticles in TCM has been gradually gaining popularity. Currently, most of the research in this field is conducted in China, with limited international collaboration. The majority of TCM nanoparticle research focuses on individual herbal compounds, while research on nanoparticle formulations of traditional herbal prescriptions is relatively scarce.

Mangiferin Protects against Angiotensin-II-Enhanced Hypertrophic Markers and Apoptosis in H9c2 Cardiomyocytes.

Hypertrophic cardiomyopathy accompanies numerous cardiovascular diseases, and the intervention of cardiac hypertrophy is an important issue to prevent detrimental consequences. Mangiferin (MGN) is a glucosylxanthone found in Mangifera indica, which exhibits anti-oxidant and anti-inflammatory properties. Various studies have demonstrated the cardioprotective potential of MGN, but the mechanisms behind its beneficial effects have not been fully revealed. Here, angiotensin-II (Ang-II) was used to induce cardiac hypertrophy, and we examined cell size, expression of hypertrophy markers (e.g., ANP, BNP, and [Formula: see text]-MHC), and oxidative stress (e.g., the ratio of NADPH/NADP[Formula: see text], the expression of p22phox and p67phox, and ROS and SOD production) of cardiomyocytes. Moreover, we assessed the activation of mitogen-activated protein kinase (MAPK) signaling (e.g., p38 and ERK) and the NF-[Formula: see text]Bp65/iNOS axis. Additionally, an annexin V/PI assay was employed to evaluate whether MGN administration can attenuate Ang-II-elicited apoptosis. Lastly, the expression of Ang-II type 1 receptor (AT1) was measured to confirm its involvement in MGN-mediated protection. Our results showed that treatment with MGN attenuated the Ang-II-induced cell size, expression of hypertrophy markers, and oxidative stress in cardiomyocytes. MGN also abrogated the activation of MAPK signaling and the NF-[Formula: see text]Bp65/iNOS axis. Additionally, MGN prevented apoptosis and downregulated the elevation of AT1 in cardiomyocytes that had been exposed to Ang-II. Altogether, these results demonstrated the potential of using MGN to ameliorate the Ang-II-associated cardiac hypertrophy, which may be due to its anti-oxidant and anti-inflammatory effects through suppression of MAPK signaling and the NF-[Formula: see text]Bp65/iNOS axis.

Efficacy of scalp acupuncture combined with conventional therapy in the intervention of post-stroke depression: A systematic review and meta-analysis.

BACKGROUND: Post-stroke depression (PSD) is a common complication following a stroke, significantly impacting patients' quality of life and mental well-being. Currently, two primary approaches are employed to treat PSD: drug therapy and non-drug therapy. Among these, acupuncture, specifically scalp acupuncture (SA), has gained attention due to its cost-effectiveness and broad social benefits. SA is a precise and direct form of acupuncture that has been utilized in the treatment of PSD. Although several randomized controlled trials (RCTs) have demonstrated the efficacy of SA in treating PSD, there is a lack of comprehensive systematic reviews. Given the limitations of existing evidence, we conducted a systematic evaluation to assess the effectiveness of SA in combination with conventional therapy (CT) for intervening in PSD. METHODS: We systematically searched five databases for articles published up until May 31, 2023, pertaining to SA treatment of PSD. A team of researchers meticulously screened and assessed these articles to identify the final included studies. After extracting relevant information and outcome indicators from the selected articles, we employed RevMan5.3 software to evaluate their quality and perform statistical analysis. Throughout our research, we strictly adhered to the PRISMA 2020 guidelines. RESULTS: A total of 11 articles were included, and a meta-analysis was conducted to evaluate the effectiveness of SA combined with CT for treating PSD. The results revealed that SA combined with CT can effectively improve the treatment's success rate for PSD and reduce the severity of depressive symptoms measured by the Self-Rating Depression Scale. However, SA combined with CT did not show significant reductions in depressive symptoms assessed by the Hamilton Rating Scale for Depression, which may be related to the inclusion of high heterogeneity articles. Importantly, the combination treatment did not lead to an increase in adverse reactions among PSD patients. CONCLUSION: While the effectiveness of SA combined with CT in treating PSD still requires further validation through rigorous randomized double-blind trials, this study provides a comprehensive collection of studies that meet the criteria for SA combined with CT in PSD treatment. It objectively and systematically evaluated the impact of SA combined with CT on PSD. Consequently, the findings of this study hold certain clinical significance.

Utility of Trimethylamine Oxide (TMAO) in Predicting Early Neurological Deterioration after Acute Ischemic Stroke.

OBJECTIVE:  To investigate whether plasma trimethylamine N-oxide (TMAO) levels might predict early neurological deterioration (END) in individuals with acute ischemic stroke. STUDY DESIGN: Cohort study. Place and Duration of the Study: Jiulongpo District Hospital of Traditional Chinese Medicine, Chongqing City, China, from January 2020 to December 2021. METHODOLOGY:  Patients presenting with ischemic stroke were classified into the END group and the non-END group. The National Institutes of Health Stroke Scale (NIHSS) total increasing by 2 points or more within 72 hours of admission was the definition of the END. Plasma TMAO levels were determined by high-performance liquid chromatographic and tandem mass spectrometry. RESULTS:  Twenty-six (25%) of the 104 patients, diagnosed with END exhibited higher TMAO levels after admission (median 1.438 vs. 0.449 nmol/mL, p=0.001). Elevated plasma TMAO levels were significant predictors of END in univariate logistic analysis. After controlling for age, gender, and cardiovascular risk factors in the multivariate conditional logistic regression model, the plasma TMAO levels in the END group remained significantly higher than those in the non-END group (OR=6.646, 95% CI 2.434-18.147, p<0.001). In receiver operator characteristic (ROC) analysis, the sensitivity and specificity of TMAO in distinguishing the END group and the non-END group at 0.564 nmol/mL cutoff value were 0.885 and 0.679, respectively. CONCLUSION: According to this research, the development of END on admission in patients with acute ischemic stroke may be positively correlated with the elevation in plasma TMAO levels. KEY WORDS:  Trimethylamine N-oxide level, Acute ischemic stroke, Early neurological deterioration, NIHSS score.

False Tendons in the Left Ventricle: Implications for Successful Ablation of Left Posterior Fascicular Tachycardias.

BACKGROUND: The anatomical substrate for left posterior fascicular ventricular tachycardia (LPF-VT) is still unclear. OBJECTIVES: The purpose of this study is to describe the endocavitary substrate of the re-entrant loop of LPF-VT. METHODS: A total of 26 consecutive patients with LPF-VT underwent an electrophysiology study and radiofrequency ablation. RESULTS: Intracardiac echocardiography imaging observed a 100% prevalence of false tendons (FTs) at the left posterior septal region in all patients, and 3 different types of FTs could be classified according to their location. In 22 patients, a P1 potential could be recorded via the multielectrode catheter from a FT. In 4 patients without a recorded P1 during LPF-VT, the earliest P2 potentials were recorded from a FT in 3 patients, and from a muscular connection between 2 posteromedial papillary muscles in 1 patient. Catheter ablation focused on the FTs with P1 or earliest P2 (in patients without P1) was successful in all 26 patients. After 19 ± 8.5 months of follow-up, no patients had recurrence of LPF-VT. CONCLUSIONS: FTs provide an electroanatomical substrate for LPF-VT and a "culprit FT" may be identified as the critical structure bridging the macro-re-entrant loop. Targeting the "culprit FT" is a novel anatomical ablation strategy that results in long-term arrhythmia-free survival.

Massage therapy can effectively relieve cancer pain: A meta-analysis.

BACKGROUND: To critically evaluate the effects of massage therapy on cancer pain. METHODS: Nine Chinese and English databases (PubMed, Cochrane Library, Embase, SCOPUS, Web of Science core, China Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang, and VIP) were systematically searched from the inception of databases to November 2022 for randomized controlled trials. According to Cochrane Collaboration, 2 reviewers independently assessed the risk of bias and extracted data from the included studies. All analyses were performed with Review Manager 5.4. RESULTS: Thirteen randomized controlled trials were included in the meta-analysis, containing 1000 patients (498 in the massage therapy group and 502 in the control group). Massage therapy could significantly relieve cancer pain in patients (standardized mean difference = -1.16, 95% confidence interval [-1.39, -0.93], P < .00001), especially those in the perioperative period and those with hematological malignancies. Foot reflexology and hand acupressure had a moderate effect on cancer pain relief, with hand acupressure being more effective. Massage duration of 10 to 30 minutes and a program length of ≥1 week had a better effect and could significantly relieve pain. The occurrence of adverse events was reported in 4 of the 13 studies, all of which were no adverse events. CONCLUSIONS: Massage therapy can be used as a complementary alternative therapy to relieve cancer pain in patients with hematological malignancies, breast cancer, and cancers of the digestive system. It is suggested that chemotherapy patients use foot reflexology, and perioperative period patients use hand acupressure. A massage duration of 10 to 30 minutes and a program length of ≥1 week is recommended to achieve better effects.

Nonpharmacological interventions for cancer-related fatigue: A literature review.

Cancer-related fatigue (CRF) is a prevalent and debilitating side effect of cancer treatment that can persist for years posttreatment, significantly impacting patients' quality of life. Given the limited efficacy of pharmacological treatments, nonpharmacological interventions are gaining attention as effective management strategies for CRF. This review aims to provide an overview of the most common nonpharmacological interventions for CRF management, including exercise therapies, psychosocial interventions, sensory art therapy, light therapy, nutritional management, traditional Chinese medicine therapies, sleep management, combination therapy, and health education. By synthesizing the findings of high-quality literature, this review presents the definition of each therapy, along with their advantages and disadvantages in treating patients with CRF. Additionally, it addresses the role of oncology nurses in the nonpharmacological management of CRF. In summary, this review aims to inform oncology nurses about the prevalent nonpharmacological interventions for CRF and explore their clinical application to facilitate the development of effective CRF management strategies in clinical practice.

Towards advanced simultaneous nitrogen removal and phosphorus recovery from digestion effluent based on anammox-hydroxyapatite (HAP) process: Focusing on a solution perspective.

In this paper, the state-of-the-art information on the anammox-HAP process is summarized. The mechanism of this process is systematically expounded, the enhancement of anammox retention by HAP precipitation and the upgrade of phosphorus recovery by anammox process are clarified. However, this process still faces several challenges, especially how to deal with the âˆ¼ 11% nitrogen residues and to purify the recovered HAP. For the first time, an anaerobic fermentation (AF) combined with partial denitrification (PD) and anammox-HAP (AF-PD-Anammox-HAP) process is proposed to overcome the challenges. By AF of the organic impurities of the anammox-HAP granular sludge, organic acid is produced to be used as carbon source for PD to remove the nitrogen residues. Simultaneously, pH of the solution drops, which promotes the dissolution of some inorganic purities such as CaCO3. In this way, not only the inorganic impurities are removed, but the inorganic carbon is supplied for anammox bacteria.

Mind-body therapies for sleep disturbance among patients with cancer: A systematic review and meta-analysis.

OBJECTIVES: To assess whether mind-body therapies (MBTs) are effective for relieving sleep disturbance among patients with cancer. DESIGN: Systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS: Seven English electronic databases were searched from the date of inception to September 2022. All RCTs that included adults (≥18 years) who were treated with mindfulness, yoga, qigong, relaxation, and hypnosis were screened. The outcome was subjective and/or objective sleep disturbance.The revised Cochrane tool (RoB 2.0) was applied to evaluate the risk of bias. The RevMan software was applied to assessed each outcome according different control groups and assessment time points. Subgroup analyses were performed according to different categories of MBTs. RESULTS: Sixty-eight RCTs (6339 participants) were identified. After requesting for missing data from corresponding authors of included RCTs, 56 studies (5051 participants) were included in the meta-analysis. The meta-analysis showed a significant immediate effect of mindfulness, yoga, relaxation, and hypnosis on subjective sleep disturbance, compared with usual care or wait list control, and the effect of mindfulness lasted at least 6 months. For objective sleep outcomes, we observed significant immediate effects of yoga on wake after sleep onset and of mindfulness on sleep onset latency and total sleep time. Compared with active control interventions, MBTs had no significant effect on sleep disturbance. CONCLUSIONS: Mindfulness, yoga, relaxation, and hypnosis were effective in sleep disturbance severity reduction among patients with cancer at post-intervention, and the effect of mindfulness lasted at least 6 months. Future MBTs studies should apply both objective and subjective sleep measurement tools.

Biomedical applications of chitosan/silk fibroin composites: A review.

Natural polymers have been used in the biomedical fields for decades, mainly derived from animals and plants with high similarities with biomacromolecules in the human body. As an alkaline polysaccharide, chitosan (CS) attracts much attention in tissue regeneration and drug delivery with favorable biocompatibility, biodegradation, and antibacterial activity. However, to overcome its mechanical properties and degradation behavior drawbacks, a robust fibrous protein-silk fibroin (SF) was introduced to prepare the CS/SF composites. Not only can CS be combined with SF via the amide and hydrogen bond formation, but also their functions are complementary and tunable with the blending ratio. To further improve the performances of CS/SF composites, natural (e.g., hyaluronic acid and collagen) and synthetic biopolymers (e.g., polyvinyl alcohol and hexanone) were incorporated. Also, the CS/SF composites acted as slow-release carriers for inorganic non-metals (e.g., hydroxyapatite and graphene) and metal particles (e.g., silver and magnesium), which could enhance cell functions, facilitate tissue healing, and inhibit bacterial growth. This review presents the state-of-the-art and future perspectives of different biomaterials combined with CS/SF composites as sponges, hydrogels, membranes, particles, and coatings. Emphasis is devoted to the biological potentialities of these hybrid systems, which look rather promising toward a multitude of applications.

Which Exercise Approaches Work for Relieving Cancer-Related Fatigue? A Network Meta-analysis.

OBJECTIVE: To determine the most effective exercise modalities for managing cancer-related fatigue during and after cancer treatment. DESIGN: Network meta-analysis (NMA) of randomized controlled trials. LITERATURE SEARCH: Seven electronic databases were systematically searched from inception to January 2022. STUDY SELECTION CRITERIA: Randomized controlled trials testing the effects of exercise on relieving cancer-related fatigue in adult patients with cancer. DATA SYNTHESIS: An NMA of 56 studies was conducted, and the PRISMA-NMA guidelines were followed when reporting results. To determine the most effective interventions, the surface under the cumulative ranking curve (SUCRA) value was calculated for each exercise modality. RESULTS: Combined aerobic and resistance exercise (standardized mean difference [SMD], 1.57; credible interval [CrI], 1.03-2.10), yoga (SMD, 1.02; CrI: 0.44, 1.60), and regular physical activity (SMD, 1.07; CrI: 0.21, 1.92) could significantly alleviate cancer-related fatigue compared to control groups (usual care, wait-list, and regular physical activity). Combined aerobic and resistance exercise (SUCRA, 97.2%) had the highest probability of efficacy, followed by yoga (SUCRA, 75.5%) and regular physical activity (SUCRA, 74.1%). During cancer treatment, combined aerobic and resistance exercise (SUCRA, 94.5%) ranked first in efficacy, followed by regular physical activity (SUCRA, 82.1%) and yoga (SUCRA, 73.8%). After cancer treatment, only combined aerobic and resistance exercise (SMD, 0.99; CrI: 0.13, 1.84) had a significant effect on cancer-related fatigue. CONCLUSION: Combined aerobic and resistance exercise, yoga, and regular physical activity were the most effective exercise modalities for alleviating cancer-related fatigue. Combined aerobic and resistance exercise is recommended during and after cancer treatment. J Orthop Sports Phys Ther 2023;53(6):1-10. Epub: 23 March 2023. doi:10.2519/jospt.2023.11251.

Self-Acupressure for Symptom Management in Cancer Patients: A Systematic Review.

CONTEXT: Acupressure is a popular nonpharmacological intervention that is increasingly proven to effectively alleviate symptoms in patients with cancer. However, the effects of self-acupressure on cancer symptom management are less clear. OBJECTIVES: This systematic review is the first to summarize the current experimental evidence on self-acupressure for symptom management in cancer patients. METHODS: Eight electronic databases were searched for experimental studies that examined self-acupressure for cancer patients with symptoms and published in peer-reviewed English or Chinese journals. The methodological quality of the included studies was evaluated using the revised Cochrane risk-of-bias assessment tool and the JBI critical appraisal checklist for quasi-experimental studies. Data were extracted as predefined and synthesized narratively. The Template for Intervention Description and Replication checklist was used to report the intervention characteristics. RESULTS: A total of 11 studies were included in this study, six as feasibility or pilot trials. The methodological quality of included studies was suboptimal. Substantial heterogeneity was observed in acupressure training, acupoint selection, intervention duration, dosage, and timing. Self-acupressure was only associated with reduced nausea and vomiting (P = 0.006 and P = 0.001). CONCLUSION: The limited evidence from this review precludes the definitive conclusions on intervention effectiveness for cancer symptoms. Future research should consider developing the standard protocol for intervention delivery, improving the methodology of self-acupressure trials, and conducting large-scale research to advance the science of self-acupressure for cancer symptom management.

Total flavonoid extract from Dracocephalum moldavica L. improves pulmonary fibrosis by reducing inflammation and inhibiting the hedgehog signaling pathway.

Dracocephalum Moldavica L. is a traditional herb for improving pharynx and relieving cough. However, the effect on pulmonary fibrosis is not clear. In this study, we explored the impact and molecular mechanism of total flavonoid extract from Dracocephalum moldavica L. (TFDM) on bleomycin-induced pulmonary fibrosis mouse model. Lung function testing, lung inflammation and fibrosis, and the related factors were detected by the lung function analysis system, HE and Masson staining, ELISA, respectively. The expression of proteins was studied through Western Blot, immunohistochemistry, and immunofluorescence while the expression of genes was analyzed by RT-PCR. The results showed that TFDM significantly improved lung function in mice, reduced the content of inflammatory factors, thereby reducing the inflammation. It was found that expression of collagen type I, fibronectin, and α-smooth muscle actin was significantly decreased by TFDM. The results further showed that TFDM interferes with hedgehog signaling pathway by decreasing the expression of Shh, Ptch1, and SMO proteins and thereby inhibiting the generation of downstream target gene Gli1 and thus improving pulmonary fibrosis. Conclusively, these findings suggest that TFDM improve pulmonary fibrosis by reducing inflammation and inhibition of the hedgehog signaling pathway.

Experience of parents in delivering pediatric tuina to children with symptoms of attention deficit hyperactivity disorder during the COVID-19 pandemic: qualitative findings from focus group interviews.

BACKGROUND: Evidence suggests that pediatric tuina, a modality of traditional Chinese medicine (TCM), might have beneficial effects on the symptoms of attention deficit hyperactivity disorder (ADHD), such as overall improvements in concentration, flexibility, mood, sleep quality, and social functioning. This study was conducted to understand the facilitators and barriers in the delivery of pediatric tuina by parents to children with ADHD symptoms. METHODS: This is a focus group interview embedded in a pilot randomized controlled trial on parent-administered pediatric tuina for ADHD in preschool children. Purposive sampling was employed to invite 15 parents who attended our pediatric tuina training program to participate voluntarily in three focus group interviews. The interviews were audio-recorded and transcribed verbatim. The data were analyzed through template analysis. RESULTS: Two themes were identified: (1) facilitators of intervention implementation and (2) barriers to intervention implementation. The theme of the facilitators of intervention implementation included the subthemes of (a) perceived benefits to children and parents, (b) acceptability to children and parents, (c) professional support, and (d) parental expectations of the long-term effects of the intervention. The theme of barriers to intervention implementation included the subthemes of (a) limited benefits for children's inattention symptoms, (b) manipulation management difficulties, and (c) limitations of TCM pattern identification. CONCLUSION: Perceived beneficial effects on the children's sleep quality and appetite and parent-child relationships, as well as timely and professional support, mainly facilitated the implementation of parent-administered pediatric tuina. Slow improvements in the children's inattention symptoms and the possible inaccuracies of online diagnosis were the dominant barriers of the intervention. Parents have high expectations for the provision of long-term professional support during their practice of pediatric tuina. The intervention presented here can be feasibly used by parents.

Progress on Prevention and Treatment of Cerebral Small Vascular Disease Using Integrative Medicine.

Cerebral small vessel disease (CSVD) is a senile brain lesion caused by the abnormal structure and function of arterioles, venules and capillaries in the aging brain. The etiology of CSVD is complex, and disease is often asymptomatic in its early stages. However, as CSVD develops, brain disorders may occur, such as stroke, cognitive dysfunction, dyskinesia and mood disorders, and heart, kidney, eye and systemic disorders. As the population continues to age, the burden of CSVD is increasing. Moreover, there is an urgent need for better screening methods and diagnostic markers for CSVD, in addition to preventive and asymptomatic- and mild-stage treatments. Integrative medicine (IM), which combines the holistic concepts and syndrome differentiations of Chinese medicine with modern medical perspectives, has unique advantages for the prevention and treatment of CSVD. In this review, we summarize the biological markers, ultrasound and imaging features, disease-related genes and risk factors relevant to CSVD diagnosis and screening. Furthermore, we discuss IM-based CSVD prevention and treatment strategies to stimulate further research in this field.
