Clinical effects and mechanisms of a Chinese patent medicine, Tongxinluo capsule, as an adjuvant treatment in coronary heart disease.

Coronary heart disease (CHD) is the leading cause of death globally, posing a serious threat to human health. However, the current treatment approaches available for CHD fall short of the ideal results. Tongxinluo (TXL) is a traditional Chinese medicine (TCM) that has been employed in the clinical treatment of cardiovascular and cerebrovascular diseases (such as angina pectoris, stroke, etc.) in China for many years and holds great potential as a prospective treatment. TXL either as a standalone treatment or in combination with interventions recommended in CHD guidelines has been shown to be effective and well tolerated in clinical trials for CHD. Drawing on the evidence from clinical trials and experimental studies, this review will focus on the cardiovascular protective properties and related mechanisms of TXL. By searching 8 Chinese and English databases, more than 4000 articles were retrieved. These articles were categorized, then read, and finally written into this review. In this review, the pharmacological properties of TXL include regulation of blood lipids, improvement of endothelial function, anti-inflammatory, antioxidant, inhibition of apoptosis and regulation of autophagy, anti-fibrosis, promotion of angiogenesis, and modulation of exosome communication. The information provided in this review will help the reader to comprehend better the insights that TCM has developed over time in practice and provide new perspectives for the treatment of CHD.

Bright light therapy has a positive effect on sleep quality in patients with cancer: A meta-analysis.

Cancer patients frequently encounter difficulties associated with suboptimal sleep quality. Bright Light Therapy (BLT), an innovative treatment approach, has shown promise in enhancing sleep quality. However, several literature reviews showed conflicting results, and more analysis should be conducted regarding detailed BLT settings on sleep. This meta-analysis was undertaken to comprehensively assess the impact of BLT on sleep quality among cancer patients. Twelve studies with 679 patients were included. Compared with the control group, BLT overall resulted in significant improvements in terms of sleep quality [g = -0.34], total sleep time [g = 0.24], wake after sleep onset [g = -0.80], and fatigue [g = -0.54]. However, it did not yield a statistically significant effect on sleep efficiency, sleep onset latency, and insomnia severity. Regarding light settings, interventions featuring light intensities >5000lux, intervention duration ≥4 weeks, spectral emission peak at 464∼465 nm, and using a lightbox demonstrated heightened efficacy in improving sleep. BLT may be considered a supplementary therapeutic option to improve sleep quality among cancer patients. However, more extensive and rigorous studies are necessary to determine the optimal timing of BLT delivery and its applicability to cancer patients across different age groups.

Effect of Tai Chi vs Aerobic Exercise on Blood Pressure in Patients With Prehypertension: A Randomized Clinical Trial.

Importance: Prehypertension increases the risk of developing hypertension and other cardiovascular diseases. Early and effective intervention for patients with prehypertension is highly important. Objective: To assess the efficacy of Tai Chi vs aerobic exercise in patients with prehypertension. Design, Setting, and Participants: This prospective, single-blinded randomized clinical trial was conducted between July 25, 2019, and January 24, 2022, at 2 tertiary public hospitals in China. Participants included 342 adults aged 18 to 65 years with prehypertension, defined as systolic blood pressure (SBP) of 120 to 139 mm Hg and/or diastolic BP (DBP) of 80 to 89 mm Hg. Interventions: Participants were randomized in a 1:1 ratio to a Tai Chi group (n = 173) or an aerobic exercise group (n = 169). Both groups performed four 60-minute supervised sessions per week for 12 months. Main Outcomes and Measures: The primary outcome was SBP at 12 months obtained in the office setting. Secondary outcomes included SBP at 6 months and DBP at 6 and 12 months obtained in the office setting and 24-hour ambulatory BP at 12 months. Results: Of the 1189 patients screened, 342 (mean [SD] age, 49.3 [11.9] years; 166 men [48.5%] and 176 women [51.5%]) were randomized to 1 of 2 intervention groups: 173 to Tai Chi and 169 to aerobic exercise. At 12 months, the change in office SBP was significantly different between groups by -2.40 (95% CI, -4.39 to -0.41) mm Hg (P = .02), with a mean (SD) change of -7.01 (10.12) mm Hg in the Tai Chi group vs -4.61 (8.47) mm Hg in the aerobic exercise group. The analysis of office SBP at 6 months yielded similar results (-2.31 [95% CI, -3.94 to -0.67] mm Hg; P = .006). Additionally, 24-hour ambulatory SBP (-2.16 [95% CI, -3.84 to -0.47] mm Hg; P = .01) and nighttime ambulatory SBP (-4.08 [95% CI, -6.59 to -1.57] mm Hg; P = .002) were significantly reduced in the Tai Chi group compared with the aerobic exercise group. Conclusions and Relevance: In this study including patients with prehypertension, a 12-month Tai Chi intervention was more effective than aerobic exercise in reducing SBP. These findings suggest that Tai Chi may help promote the prevention of cardiovascular disease in populations with prehypertension.

A follow-up study on factors affecting the recovery of patients with hypothyroidism in different selenium environments.

BACKGROUND: Hypothyroidism is a major manifestation of autoimmune thyroid diseases (AITD). We previously reported that a low selenium (Se) status was linked to an elevated prevalence of thyroid diseases. We hypothesized that Se status may also influence the restoration of thyroid function. Thus, this study aimed to investigate the factors affecting the recovery of thyroid function in patients with (sub-)clinical hypothyroidism, with a specific focus on Se status. METHODS: We conducted a 6-year prospective cohort study comparing two counties with different Se concentrations. Demographic and disease data were collected from 1,190 individuals (549 Se-adequate and 641 Se-deficient) who completed a follow-up study in 2019. In addition, urinary iodine (I) levels, thyroid function, and serum and nail Se levels were measured. Logistic regression was used to investigate the relationship between Se deficiency and recovery of thyroid function. RESULTS: Sex and smoking status was similar between the two counties studied. Thyroid function recovery rate was significantly higher in Se-deficient counties (46.0% vs. 30.6%, P = 0.008). In the multivariate analysis, our results show that female sex (odds ratio [OR] (95% confidence interval [CI]) = 1.875 (1.080-3.257), P = 0.026] and increasing age [OR (95%CI) = 1.028(1.007-1.049), P = 0.009] were associated with the recovery rate. Additionally, our study revealed that while Se status was significant in the univariate analysis, this association appeared to disappear in the multivariate analysis. CONCLUSIONS: Female sex and increasing age have unfavorable effects on the recovery of thyroid function in patients over 30 years of age with (sub-) clinical hypothyroidism.

Removal of Wires for Sternal Internal Fixation After Cardiac Surgery in Adolescents.

Objective: The objective of this study was to assess the safety and patient satisfaction of sternal wire removal surgery, rendering reference for clinical practice in the future. Methods: A total of 70 adolescent patients with completely healed sternum and no other diseases or able to receive surgery were randomly selected and subjected to sternal wire removal surgery. Besides, relevant data including patient age, gender, wire rupture, reason for wire removal, postoperative wire residuals, patient satisfaction, age at cardiac surgery, waiting time after cardiac surgery, and removal duration were recorded. Results: Raptured wire group exhibited higher proportions of males and chest pain cases and longer operative time than unruptured wire group. The demand for wire removal had no relation to gender, but patients receiving surgery due to chest pain were mainly aged 12-15 years old, those undergoing surgery due to employment and further education were mainly aged 9-12 years old, and those subjected to surgery sue to ruptures found in physical examinations were mainly aged 6-9 years old. According to statistics of wire rupture position, the rupture of the 4th wire accounted for the largest proportion, and rupture of multiple wires was found in some patients. No statistically significant differences were found in gender, age, age at cardiac surgery, and waiting time after cardiac surgery between patients with only one wire ruptured and those with multiple wires ruptured. Patients were grouped based on the absence and presence of chest pain, and it was found that chest pain group had a longer removal duration, but comparable age at cardiac surgery and waiting time after cardiac surgery, and the waiting time after cardiac surgery was a risk factor for chest pain. The waiting time after cardiac surgery was positively correlated with operative time, so we recommend that if there were symptoms of chest discomfort, it should be removed as soon as possible. However, due to the needs of the patients, no control group was set up, which is the limitation of this study. In the next step, we will conduct more long-term observation of the patients to confirm whether the chest pain can be relieved by itself without removing the wire. Conclusion: This study found that for adolescent patients with chest pain or other life troubles after cardiac surgery, removing the sternal internal fixation wire can quickly and effectively relieve the troubles, and is a safe and reliable treatment means. Therefore, if it is necessary to remove the wire, it should be removed as soon as possible to avoid wire breakage and increase the difficulty of surgery.

Chemopreventive Effects of Polysaccharides and Flavonoids from Okra Flowers in Azomethane/Dextran Sulfate Sodium-Induced Murine Colitis-Associated Cancer.

Okra flowers are a good source of polysaccharides and flavonoids, with biological activities of anti-inflammatory action and modulation of the gut microbiota. Previously, we reported that flavonoid-rich extracts from okra flowers (AFE) presented effective anti-colorectal cancer (CRC) activity in CRC cells as well as xenograft models, but their role in colitis-associated cancer (CAC) is unidentified. In this study, we aimed to evaluate the effects of AFE and APE (polysaccharides extracted from okra flowers) on the CAC symptoms of azoxymethane (AOM)/dextran sodium sulfate (DSS)-intervened mice. The results showed that APE and AFE exert potent efficacy in inhibiting colitis and colorectal tumorigenesis stimulated by AOM/DSS, characterized by decreased colonic shortening, DAI score, and tumor numbers. Compared with the control group, APE/AFE alleviated the microbiota dysbiosis driven by AOM/DSS. In addition, AFE elicited its anticancer activity through regulation of NFκB/IL-6/Stat3, JAK2/Stat3, MAPKs, PI3K/AKT, and Wnt/ß-catenin signal transductions in AOM/DSS mice, which was consistent with a vitro model of CT26 cells, while APE treatment exhibited anticancer activity through regulation of Nrf2/IL-6, MAPKs, PI3K/AKT, and Wnt/ß-catenin signal transductions in the AOM/DSS mouse model. Collectively, our studies revealed, for the first time, that flavonoids and polysaccharides from okra flowers possess the ability to attenuate colitis and colorectal tumorigenesis, with them having great potential to become promising candidates against CRC.

[Effects of mycorrhizal planting on small molecular chemical components of Dendrobium officinale].

This study aimed to provide a scientific basis for the application of the mycorrhizal planting technology of Dendrobium officinale by investigating the effects of mycorrhizal planting on the fingerprints of D. officinale and the content of six chemical components. Seventeen samples of D. officinale under mycorrhizal and conventional planting were collected from four regions, such as Jinhua of Zhejiang. The HPLC fingerprints were established to evaluate the similarity of the samples. The content of six chemical components of the samples was determined by HPLC. There were 15 common peaks in the fingerprints, and five of them were identified by marker compounds, which were naringenin, 4,4'-dihydroxy-3,5-dimethoxybibenzyl, 3,4'-dihydroxy-5-methoxybibenzyl, 3',4-dihydroxy-3,5'-dimethoxybibenzyl(gigantol), and 3,4-dihydroxy-4',5-dimethoxybibenzyl(DDB-2). The similarities of the fingerprints of mycorrhizal and conventional planting samples and the control fingerprint were in the ranges of 0.733-0.936 and 0.834-0.942, respectively. The influences of mycorrhizal planting on fingerprints were related to planting regions, the germplasm of D. officianle, and the amount of fungal agent. The content of six chemical components in the samples varied greatly, and the content of DDB-2 was the highest, ranging from 69.83 to 488.47 µg·g~(-1). The mycorrhizal planting samples from Chongming of Shanghai and Taizhou of Jiangsu showed an increase in the content of 5-6 components, while samples from Zhangzhou of Fujian and Jinhua of Zhejiang showed an increase in the content of 1-2 components. The results showed that mycorrhizal planting technology did not change the chemical profile of small molecular chemical components of D. officinale, but affected the content of chemical components such as bibenzyls, which has a good application prospect.

Effect and possible mechanisms of saponins in Chinese herbal medicine exerts for the treatment of myocardial ischemia-reperfusion injury in experimental animal: a systematic review and meta-analysis.

Introduction: Preventing ischemia-reperfusion injury is the main direction of myocardial infarction treatment in the convalescent stage. Some studies have suggested that saponins in Traditional Chinese medicine (TCM) preparations can protect the myocardium by various mechanisms. Our meta-analysis aims to evaluate the efficacy of TCM saponins in treating myocardial ischemia-reperfusion injury (MIRI) and to summarize the potential molecular mechanisms further. Methods: We conducted a literature search in six electronic databases [Web of Science, PubMed, Embase, Cochrane Library, Sinomed, China National Knowledge Infrastructure (CNKI)] until October 2022. Results: Seventeen eligible studies included 386 animals (254 received saponins and 132 received vehicles). The random effect model is used to calculate the combined effect. The effect size is expressed as the weighted average difference (WMD) and 95% confidence interval (CI). Compared with placebo, saponins preconditioning reduced infarct size after MIRI significantly (WMD: -3.60,95% CI: -4.45 to -2.74, P < 0.01, I2: 84.7%, P < 0.001), and significantly increased EF (WMD: 3.119, 95% CI: 2.165 to 4.082, P < 0.01, I2: 82.9%, P < 0.0 L) and FS (WMD: 3.157, 95% CI: 2.218 to 4.097, P < 0.001, I2: 81.3%, P < 0.001). Discussion: The results show that the pre-administration of saponins from TCM has a significant protective effect on MIRI in preclinical studies, which provides an application prospect for developing anti-MIRI drugs with high efficiency and low toxicity.

Effects of PTH on osteoblast bioenergetics in response to glucose.

Parathyroid hormone acts through its receptor, PTHR1, expressed on osteoblasts, to control bone remodeling. Metabolic flexibility for energy generation has been demonstrated in several cell types dependent on substrate availability. Recent studies have identified a critical role for PTH in regulating glucose, fatty acid and amino acid metabolism thus stimulating both glycolysis and oxidative phosphorylation. Therefore, we postulated that PTH stimulates increased energetic output by osteoblasts either by increasing glycolysis or oxidative phosphorylation depending on substrate availability. To test this hypothesis, undifferentiated and differentiated MC3T3E1C4 calvarial pre-osteoblasts were treated with PTH to study osteoblast bioenergetics in the presence of exogenous glucose. Significant increases in glycolysis with acute ∼1 h PTH treatment with minimal effects on oxidative phosphorylation in undifferentiated MC3T3E1C4 in the presence of exogenous glucose were observed. In differentiated cells, the increased glycolysis observed with acute PTH was completely blocked by pretreatment with a Glut1 inhibitor (BAY-876) resulting in a compensatory increase in oxidative phosphorylation. We then tested the effect of PTH on the function of complexes I and II of the mitochondrial electron transport chain in the absence of glycolysis. Utilizing a novel cell plasma membrane permeability mitochondrial (PMP) assay, in combination with complex I and II specific substrates, slight but significant increases in basal and maximal oxygen consumption rates with 24 h PTH treatment in undifferentiated MC3T3E1C4 cells were noted. Taken together, our data demonstrate for the first time that PTH stimulates both increases in glycolysis and the function of the electron transport chain, particularly complexes I and II, during high energy demands in osteoblasts.

Effect of an Online Mindfulness-Based Stress Reduction Intervention on Postpandemic Era Nurses' Subjective Well-being, Job Burnout, and Psychological Adaptation.

This study explores the effects of an online mindfulness-based stress reduction intervention on postpandemic era nurses' subjective well-being, job burnout, and psychological adaptation. Previous studies on the psychological adaptability of nurses mainly focused on investigation rather than intervention. Ninety nurses were randomly classified into an intervention or control group. The intervention group received weekly online mindfulness-based stress reduction training for 8 weeks. The Subjective Well-being, Job Burnout, and Psychological Use scales were administered pre- and postintervention. Postintervention, nurses' positive emotions and life satisfaction significantly improved. Nurses' psychological adaptation was significantly higher postintervention than preintervention. The total scores for negative emotion, low personal accomplishment, and job burnout were significantly lower postintervention than preintervention. The scores for positive emotion and life satisfaction in the intervention group were significantly higher than those in the control group, and the scores for low personal accomplishment in the intervention group were significantly lower than those in the control group. Online mindfulness-based stress reduction interventions can improve nurses' subjective well-being, reduce job burnout, and improve their level of psychological adaptability. Moreover, it could promote nurses' ability to communicate mindfully with patients and their families. This intervention could help promote the development of mindfulness in the nursing field.

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.

Massage therapy significantly improves cancer-related fatigue in cancer patients: a meta-analysis of randomized controlled trials.

PURPOSE: This study was designed to investigate the effectiveness and safety of massage therapy in cancer-related fatigue (CRF) and to provide a reference for the future management of CRF. METHODS: Eight databases (PubMed, Embase, Cochrane Library, CINAHL, Sinomed, Chinese Scientific Journal database (VIP), Wanfang, and China National Knowledge Infrastructure (CNKI)) were systematically reviewed from inception to May 2022 for randomized controlled trials. Two reviewers critically and independently assessed the risk of bias using Cochrane Collaboration criteria and extracted correlated data using the designed form. The meta-analysis was performed using RevMan 5.3 to calculate the pooled effect sizes and 95% confidence intervals (CIs). Sensitivity analysis was performed to find the source of the heterogeneity. Publication bias was assessed via funnel plot analysis and the Egger test. RESULT: A total of 11 qualified studies that included 789 patients (massage therapy group: 389; control group: 400) were included in the meta-analysis. Massage therapy had a marked effect on fatigue in cancer patients [standardized mean difference (SMD) = - 1.69, 95% CI (- 2.46, - 0.93), P < 0.01], especially in breast cancer [SMD = - 1.62, 95% CI (- 2.18, - 1.05), P < 0.01]. Reflexology [SMD = - 2.71, 95% CI (- 4.65, - 0.77), P < 0.01] and Chinese massage [SMD = - 1.14, 95% CI (- 1.95, - 0.33), P < 0.01] can have a more significant effect on fatigue. Massage time is 20 to 40 min [SMD = - 2.39, 95% CI (- 4.13, - 0.66), P < 0.01], twice a week [SMD = - 3.46, 95% CI (- 5.47, - 1.45), P < 0.01] for 3-5 weeks [SMD = - 2.36, 95% CI (- 3.53, - 1.19), P < 0.01], which is more effective in relieving fatigue in cancer patients. Five studies described the occurrence of adverse events and only two studies had adverse events. CONCLUSION: Massage therapy can be effective in relieving fatigue in cancer patients. Current evidence suggests that reflexology is the most effective approach to relieve fatigue, particularly in the breast cancer patients. The optimal intervention frequency and cycle for massage therapy is twice a week for 3-5 weeks, and the optimal duration is 20-40 min.

[Research progress in strigolactones and application prospect in medicinal plants].

Strigolactones(SLs) are a class of sesquiterpenoids derived from the carotenoid biosynthesis pathway with the core carbon skeleton consisting of tricyclic lactone(ABC tricyclic ring) and α,ß-unsaturated furan ring(D ring). SLs are widely distributed in higher plants and are symbiotic signals between plants and Arbuscular mycorrhiza(AM), which play key roles in the evolution of plant colonizing terrestrial habitats. As a new type of plant hormone, SLs possess such important biological functions as inhibiting shoot branching(tillers), regulating root architecture, promoting secondary growth, and improving plant stress resistance. Therefore, SLs have attracted wide attention. The biological functions of SLs are not only closely related to the formation of "excellent shape and quality" of Chinese medicinal materials but also have important practical significance for the production of high-quality medicinal materials. However, SLs have been currently widely studied in model plants and crops such as Oryza sativa and Arabidopsis thaliana, and few related studies have been reported on SLs in medicinal plants, which need to be strengthened. This review focused on the latest research progress in the isolation and identification, biological and artificial synthesis pathways, biosynthesis sites and transport modes, signal transduction pathways and mechanisms, and biological functions of SLs, and prospected the research on the regulation mechanism of SLs in the growth and development of medicinal plants and their related application on targeted regulation of Chinese herbal medicine production, which is expected to provide some references for the in-depth research on SLs in the field of Chinese medicinal resources.

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.

The Chinese herbal prescription JieZe-1 inhibits caspase-1-dependent pyroptosis induced by herpes simplex virus-2 infection in vitro.

OBJECTIVE: JieZe-1 (JZ-1), a Chinese herbal prescription, has an obvious effect on genital herpes, which is mainly caused by herpes simplex virus type 2 (HSV-2). Our study aimed to address whether HSV-2 induces pyroptosis of VK2/E6E7 cells and to investigate the anti-HSV-2 activity of JZ-1 and the effect of JZ-1 on caspase-1-dependent pyroptosis. METHODS: HSV-2-infected VK2/E6E7 cells and culture supernate were harvested at different time points after the infection. Cells were co-treated with HSV-2 and penciclovir (0.078125 mg/mL) or caspase-1 inhibitor VX-765 (24 h pretreatment with 100 µmol/L) or JZ-1 (0.078125-50 mg/mL). Cell counting kit-8 assay and viral load analysis were used to evaluate the antiviral activity of JZ-1. Inflammasome activation and pyroptosis of VK2/E6E7 cells were analyzed using microscopy, Hoechst 33342/propidium iodide staining, lactate dehydrogenase release assay, gene and protein expression, co-immunoprecipitation, immunofluorescence, and enzyme-linked immunosorbent assay. RESULTS: HSV-2 induced pyroptosis of VK2/E6E7 cells, with the most significant increase observed 24 h after the infection. JZ-1 effectively inhibited HSV-2 (the 50% inhibitory concentration = 1.709 mg/mL), with the 6.25 mg/mL dose showing the highest efficacy (95.76%). JZ-1 (6.25 mg/mL) suppressed pyroptosis of VK2/E6E7 cells. It downregulated the inflammasome activation and pyroptosis via inhibiting the expression of nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing protein 3 (P < 0.001) and interferon-γ-inducible protein 16 (P < 0.001), and their interactions with apoptosis-associated speck-like protein containing a caspase recruitment domain, and reducing cleaved caspase-1 p20 (P < 0.01), gasdermin D-N (P < 0.01), interleukin (IL)-1ß (P < 0.001), and IL-18 levels (P < 0.001). CONCLUSION: JZ-1 exerts an excellent anti-HSV-2 effect in VK2/E6E7 cells, and it inhibits caspase-1-dependent pyroptosis induced by HSV-2 infection. These data enrich our understanding of the pathologic basis of HSV-2 infection and provide experimental evidence for the anti-HSV-2 activity of JZ-1.

Elucidation of the underlying mechanism of Hua-ban decoction in alleviating acute lung injury by an integrative approach of network pharmacology and experimental verification.

The pathogenic hyper-inflammatory response has been regarded as the major cause of the severity and death related to acute lung injury (ALI). Hua-ban decoction (HBD) is a classical prescription in traditional Chinese medicine (TCM). It has been extensively used to treat inflammatory diseases; however, its bioactive components and therapeutic mechanisms remain unclear. Here, we established a lipopolysaccharide (LPS)-induced ALI model that presents a hyperinflammatory process to explore the pharmaco-dynamic effect and underlying molecular mechanism of HBD on ALI. In vivo, we confirmed that in LPS-induced ALI mice, HBD improved pulmonary injury by via down-regulating the expression of proinflammatory cytokines, including IL-6, TNF-α, and macrophage infiltration, as well as macrophage M1 polarization. Moreover, in vitro experiments in LPS-stimulated macrophages demonstrated that the potential bioactive compounds of HBD inhibited the secretion of IL-6 and TNF-α. Mechanically, the data revealed that HBD treatment of LPS-induced ALI acted via NF-κB pathway, which regulated macrophage M1 polarization. Additionally, two major HBD compounds, i.e., quercetin and kaempferol, showed a high binding affinity with p65 and IkBα. In conclusion, the data obtained in this study demonstrated the therapeutic effects of HBD, which indicates the possibility for the development of HBD as a potential treatment for ALI.

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.

Whole-genome Duplication Reshaped Adaptive Evolution in A Relict Plant Species, Cyclocarya paliurus.

Cyclocarya paliurus is a relict plant species that survived the last glacial period and shows a population expansion recently. Its leaves have been traditionally used to treat obesity and diabetes with the well-known active ingredient cyclocaric acid B. Here, we presented three C. paliurus genomes from two diploids with different flower morphs and one haplotype-resolved tetraploid assembly. Comparative genomic analysis revealed two rounds of recent whole-genome duplication events and identified 691 genes with dosage effects that likely contribute to adaptive evolution through enhanced photosynthesis and increased accumulation of triterpenoids. Resequencing analysis of 45 C. paliurus individuals uncovered two bottlenecks, consistent with the known events of environmental changes, and many selectively swept genes involved in critical biological functions, including plant defense and secondary metabolite biosynthesis. We also proposed the biosynthesis pathway of cyclocaric acid B based on multi-omics data and identified key genes, in particular gibberellin-related genes, associated with the heterodichogamy in C. paliurus species. Our study sheds light on evolutionary history of C. paliurus and provides genomic resources to study the medicinal herbs.

Mitochondrial pyruvate carrier influences ganoderic acid biosynthesis in Ganoderma lucidum.

Mitochondrial pyruvate carriers (MPCs), located in the inner membrane of mitochondria, are essential carriers for pyruvate to enter mitochondria. MPCs regulate a wide range of intracellular metabolic processes, such as glycolysis, the tricarboxylic acid cycle (TCA cycle), fatty acid metabolism, and amino acid metabolism. However, the metabolic regulation of MPCs in macrofungi is poorly studied. We studied the role of MPCs in Ganoderma lucidum (GlMPC) on ganoderic acid (GA) biosynthesis regulation in G. lucidum. In this study, we found that the mitochondrial/cytoplasmic ratio of pyruvate was downregulated about 75% in GlMPC1- and GlMPC2-silenced transformants compared with wild type (WT). In addition, the GA content was 17.72 mg/g and increased by approximately 50% in GlMPC1- and GlMPC2-silenced transformants compared with WT. By assaying the expression levels of three key enzymes and the enzyme activities of isocitrate dehydrogenase (IDH) and α-ketoglutarate dehydrogenase (α-KGDH) of the TCA cycle in GlMPC1- and GlMPC2-silenced transformants, it was found that the decrease in GlMPCs activity did not significantly downregulate the TCA cycle rate, and the enzyme activity of IDH increased by 44% compared with WT. We then verified that fatty acid ß-oxidation (FAO) supplements the TCA cycle by detecting the expression levels of key enzymes involved in FAO. The results showed that compared with WT, the GA content was 1.14 mg/g and reduced by approximately 40% in co-silenced transformants. KEY POINTS: • GlMPCs affects the distribution of pyruvate between mitochondria and the cytoplasm. • Acetyl-CoA produced by FAO maintains the TCA cycle. • Acetyl-CoA produced by FAO promotes the accumulation of GA.

[Overview on the modern development of fire needling device: from tradition to innovation].

The appropriate needle device is crucial for obtaining the curative effect of fire needling therapy. The article introduces the material specification, clinical operation, indications, characteristics and advantages of the contemporary traditional fire needling devices (e.g. He's fire needle and Shi 's fire needle) and the contemporary new-type ones (e.g. fire needling with filiform needle and micro-needle); and determines the innovations of modern fire needling. It is anticipated that the needle specifications, production process and operation standard of fire needling devices should be further unified so as to provide the references for the selection of fire needling devices in treatment based on clinical syndrome differentiation and expand the clinical application of fire needling therapy.
