The Effectiveness of Auricular Acupressure on Chronic Musculoskeletal Pain: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Objectives: To assess the effectiveness of auricular acupressure (AA) in managing pain and disability in individuals with chronic musculoskeletal pain. Materials and Methods: A systematic search on six electronic databases was performed from their inception to May 7, 2023, to identified relevant randomized controlled trials (RCTs). Two independent reviewers screened the abstracts and full texts, extracted data, and assessed risk of bias using RoB 2. The primary outcomes were pain intensity and disability. The secondary outcomes were pain pressure thresholds, pain catastrophizing level, and fear avoidance beliefs. A random-effects model was used for meta-analyses. The certainty of evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation. Sensitivity analyses were conducted after removing low-quality papers. Results: Of 633 identified records, six studies involving 496 participants were included. All included studies compared the effectiveness of AA with sham controls in treating various chronic musculoskeletal pain. Four meta-analyses were conducted to compare the effectiveness of AA with sham controls. Low-quality evidence supported that AA had a large effect size on postintervention subjective pain reduction (standardized mean difference [SMD] = -0.95; 95% confidence interval [CI]: -1.36 to -0.54; p = 0.00; I2 = 52.61%); moderate-quality evidence substantiated that AA had a large effect size on enhancing postintervention pressure pain threshold (SMD = -0.55; 95% CI: -0.88 to -0.23; p = 0.00; I2 = 0%). There was low-quality evidence that AA had a large effect on reducing postintervention disability (SMD = -0.68; 95% CI: -1.24 to -0.12; p = 0.02; I2 = 51.33%). Our sensitivity analysis reaffirmed the same conclusion regarding pain reduction immediately after the intervention. Fourteen participants reported minimal adverse events, including soreness, tenderness, irritation, and redness, which disappeared within 1-7 days. Discussion: Our systematic review revealed that AA significantly improved pain, pressure pain thresholds, and disability in individuals with various chronic musculoskeletal pain conditions immediately post-treatment compared with sham treatment. Given the paucity of studies and inconsistent protocols, future RCTs are warranted to evaluate the effectiveness of AA in people with chronic musculoskeletal pain at a longer follow-up with detailed protocols, which allows researchers and clinicians to optimize AA intervention. Conclusion: AA has immediate post-treatment benefits for chronic musculoskeletal pain, whereas its effects at the 1- or 6-month follow-up remain uncertain.

Analysis of mechanism, therapeutic strategies, and potential natural compounds against atherosclerosis by targeting iron overload-induced oxidative stress.

Ferroptosis is a novel form of cell demise characterized primarily by the reduction of trivalent iron to divalent iron, leading to the release of reactive oxygen species (ROS) and consequent induction of intense oxidative stress. In atherosclerosis (AS), highly accumulated lipids are modified by ROS to promote the formation of lipid peroxides, further amplifying cellular oxidative stress damage to influence all stages of atherosclerotic development. Macrophages are regarded as pivotal executors in the progression of AS and the handling of iron, thus targeting macrophage iron metabolism holds significant guiding implications for exploring potential therapeutic strategies against AS. In this comprehensive review, we elucidate the potential interplay among iron overload, inflammation, and lipid dysregulation, summarizing the potential mechanisms underlying the suppression of AS by alleviating iron overload. Furthermore, the application of Traditional Chinese Medicine (TCM) is increasingly widespread. Based on extant research and the pharmacological foundations of active compounds of TCM, we propose alternative therapeutic agents for AS in the context of iron overload, aiming to diversify the therapeutic avenues.

Network pharmacology combined with experimental validation reveals the mechanism of action of erpixing granules on functional dyspepsia.

ETHNOPHARMACOLOGICAL RELEVANCE: Functional dyspepsia (FD) is a prevalent gastrointestinal disorder characterised by high incidence and recurrence rates, posing significant health risks. Erpixing Granules (EPX), approved by the National Food and Drug Administration in 2002, are known for their spleen and stomach invigorating properties, effectively treating FD. However, its mechanism of action remains unclear. AIM OF THE STUDY: This study aims to elucidate EPX's mechanism of treating FD through network pharmacology, and experimental validation using FD animal models. METHODS: In this study, the chemical composition of EPX in positive and negative ion modes was analyzed by UHPLC-Q-TOF MS. The mass spectral data were processed and analyzed using MS-DIAL software to automatically match compound fragment information and identify the known components with the compound database to obtain the active components of EPX. SwissTargetPrediction was used to obtain EPX targets, while FD-related targets were sourced from GeneCards, OMIM and DisGeNET databases. A protein-protein interaction (PPI) network was constructed using the STRING platform, and potential signalling pathways of EPX were determined through Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Finally, an FD model was established in rates by administering a 0.1% iodoacetamide sucrose solution, followed by tail clamp stimulation to experimentally validate the network pharmacology findings. RESULTS: Our results revealed 139 effective ingredients in EPX, targeting 60 core FD-related genes. PPI network analysis identified EGFR, CTNNB1 and NFκB1 as core target genes. The KEGG pathway analysis indicated that EPX can modulate FD progression through the PI3K/AKT signalling pathway. Animal experiments demonstrated EPX's capacity to increase body mass, food intake and food utilisation efficiency in FD rats, alongside increased gastric juice secretion, pepsin activity, trypsin activity, cholesterol, bile acid and bilirubin activity. HE examination revealed that EPX improved the inflammatory infiltration of gastric mucosal cells in rats. Furthermore, EPX also promoted gastric emptying and intestinal propulsion in mice. These results suggest that EPX improves spleen and stomach function, enhances the protective effect on the spleen and stomach and promotes food digestion and absorption. Immunofluorescence studies revealed upregulated expression of PI3K, AKT and ANO1 proteins in gastric tissue following EPX administration, while Western blotting indicated increased expression of SCF and C-kit proteins. CONCLUSION: Suggesting EPX's anti-FD effect may involve the regulation of the SCF/C-kit signalling pathway and activation of downstream PI3K/AKT signalling pathway, thereby promoting gastrointestinal motility and improving FD symptoms.

The mechanism of Gejie Zhilao Pill in treating tuberculosis based on network pharmacology and molecular docking verification.

Introduction: Gejie Zhilao Pill (GJZLP), a traditional Chinese medicine formula is known for its unique therapeutic effects in treating pulmonary tuberculosis. The aim of this study is to further investigate its underlying mechanisms by utilizing network pharmacology and molecular docking techniques. Methods: Using TCMSP database the components, potential targets of GJZLP were identified. Animal-derived components were supplemented through the TCMID and BATMAN-TCM databases. Tuberculosis-related targets were collected from the TTD, OMIM, and GeneCards databases. The intersection target was imported into the String database to build the PPI network. The Metascape platform was employed to carry out Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Heatmaps were generated through an online platform (https://www.bioinformatics.com.cn). Molecular docking was conducted between the core targets and core compounds to explore their binding strengths and patterns at the molecular level. Results: 61 active ingredients and 118 therapeutic targets were identified. Quercetin, Luteolin, epigallocatechin gallate, and beta-sitosterol showed relatively high degrees in the network. IL6, TNF, JUN, TP53, IL1B, STAT3, AKT1, RELA, IFNG, and MAPK3 are important core targets. GO and KEGG revealed that the effects of GJZLP on tuberculosis mainly involve reactions to bacterial molecules, lipopolysaccharides, and cytokine stimulation. Key signaling pathways include TNF, IL-17, Toll-like receptor and C-type lectin receptor signaling. Molecular docking analysis demonstrated a robust binding affinity between the core compounds and the core proteins. Stigmasterol exhibited the lowest binding energy with AKT1, indicating the most stable binding interaction. Discussion: This study has delved into the efficacious components and molecular mechanisms of GJZLP in treating tuberculosis, thereby highlighting its potential as a promising therapeutic candidate for the treatment of tuberculosis.

The efficacy and safety of Dachaihu decoction in the treatment of nonalcoholic fatty liver disease: a systematic review and meta-analysis.

Background: Nonalcoholic fatty liver disease (NAFLD), also known as metabolic associated fatty liver disease (MAFLD), is a common liver condition characterized by excessive fat accumulation in the liver which is not caused by alcohol. The main causes of NAFLD are obesity and insulin resistance. Dachaihu decoction (DCHD), a classic formula in traditional Chinese medicine, has been proved to treat NAFLD by targeting different aspects of pathogenesis and is being progressively used in the treatment of NAFLD. DCHD is commonly applied in a modified form to treat the NAFLD. In light of this, it is imperative to conduct a systematic review and meta-analysis to assess the effectiveness and safety of DCHD in the management of NAFLD. There is a need for a systematic review and meta-analysis to assess the effectiveness and safety of modified DCHD in treating NAFLD. Objective: The objective of this meta-analysis was to systematically assess the clinical effectiveness and safety of DCHD in treating NAFLD. Methods: This meta-analysis adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Including seven databases, both Chinese and English databases were searched for relevant studies. The quality of included studies was carefully assessed using the bias risk assessment tool in the Cochrane Handbook. Eligible articles were the source of extracted data which was meta-analyzed by using Review Manager 5.4 and Stata 17.0. Results: A total of 10 studies containing 825 patients were included. Compared with conventional treatments, combined treatment could clearly improve the liver function of NAFLD patients, which could reduce the levels of ALT (MD = -7.69 U/L, 95% CI: -11.88 to -3.51, p < 0.001), AST (MD = -9.58 U/L, 95% CI: -12.84 to -6.33, p < 0.01), and it also had a certain impact on regulating lipid metabolism, which could reduce the levels of TC (MD = -0.85 mmol/L, 95% CI: -1.22 to 0.48, p < 0.01), TG (MD = -0.45 mmol/L, 95% CI: -0.64 to 0.21, p < 0.01). Adverse event showed that DCHD was relatively safe. Due to the inclusion of less than 10 trials in each group, it was not possible to conduct a thorough analysis of publication bias. Conclusion: According to the meta-analysis, in the treatment of the NAFLD, it is clear that the combination of DCHD was advantages over conventional treatment alone in improving liver function, regulating lipid metabolism. Additionally, DCHD demonstrates a relatively safe profile. Nevertheless, due to limitations in the quality and quantity of the studies incorporated, the effectiveness and safety of DCHD remain inconclusive. Consequently, further high-quality research is imperative to furnish more substantial evidence supporting the widespread clinical application of DCHD.

Treatment of a patient with severe cerebral malaria during the COVID-19 pandemic in China: A case report.

BACKGROUND: On June 30, 2021, China received certification from the World Health Organization for malaria elimination. However, this certification does not signify the absence of malaria within China. Due to the increasing frequency of international exchanges and collaborations, the threat of imported malaria persists in China. Consequently, the prevention and control of imported malaria have become a primary focus for our country to maintain its malaria elimination status. CASE SUMMARY: Herein, we present a case report of a 53-year-old Chinese man who worked in Africa for nearly two years. He was diagnosed with malaria in the Democratic Republic of the Congo between November 19 and November 23, 2022. After receiving effective treatment with oral antimalarial drugs, his condition improved, allowing him to return to China. He was later admitted to our hospital on January 12, 2023, during the coronavirus disease 2019 pandemic in Huangshi, China. Through a thorough evaluation of the patient's symptoms, clinical signs, imaging and laboratory test results, and epidemiological data, he was rapidly diagnosed with severe cerebral malaria. The patient underwent successful treatment through a series of intensive care unit interventions. CONCLUSION: The successful treatment of this imported case of severe cerebral malaria provides a valuable reference for managing patients with similar malaria infections and has significant clinical implications.

The effect of Bushenhuoxue nutritional decoction in the treatment of overweight patients with polycystic ovarian syndrome.

Objective: To assess the effect of Traditional Chinese Medicine (TCM) nutrition treatment (Bushenhuoxue nutritional decoction) in overweight patients with polycystic ovary syndrome (PCOS). Methods: Retrospective analysis of 96 overweight patients with PCOS who received treatment in our hospital from October 2020 to June 2022 was done. Among them, 46 patients received routine drug treatment and daily dietary intervention (control group), while 50 patients received additional TCM nutrition support in addition to routine treatment (observation group). Glucose and lipid metabolism indicators and hormone levels were compared between the two groups before and after the treatment. Ovulation rate, pregnancy rate, and adverse reactions were compared between both groups one year after the treatment. Results: After treatment, the improvement of glucose and lipid metabolism indicators and hormone levels in the observation group was significantly better than in the control group (P<0.05). After treatment, the TCM syndrome scores of the two groups were lower than that before treatment (P < 0.001), and the TCM syndrome scores of the observation group was lower than that of the control group (P < 0.001).Ovulation and pregnancy rates were significantly higher in the observation group compared to the control group at 1-year follow up (P<0.05), and the incidence of adverse reactions in the observation group was significantly lower than that in the control group (P<0.05). Conclusions: Combined with conventional drug treatment, TCM nutrition treatment can significantly improve glucose and lipid metabolism, hormone levels, and TCM syndrome of overweight PCOS patients, increase the ovulation and pregnancy rates, and reduce potential adverse reactions.

Huanglian Wendan Decoction Improves Insomnia in Rats by Regulating BDNF/TrkB Signaling Pathway Through Gut Microbiota-Mediated SCFAs and Affecting Microglia Polarization.

Insomnia is a typical type of sleep disorder. Huanglian Wendan Decoction (HWD) is a traditional Chinese medicine (TCM) with the effects of regulating Qi, drying dampness and resolving phlegm, calming the mind, and relieving irritation. This study aims to investigate the effect of HWD on insomnia in rats and its mechanism. Para-chlorophenylalanine (PCPA)-induced insomnia in rats was used for in vivo experiments and then treated with HWD. Behavioral tests, Western blot, real-time PCR, immunofluorescent staining, 16S rRNA sequencing were conducted. The content of SCFAs was determined by GC-MS. Acetic acid-pretreated rat hippocampal nerve cells were used for in vitro experiments. The results showed that HWD significantly improved the learning memory ability, decreased sleep latency, and prolonged sleep duration in insomniac rats. HWD reduced TNF-α and IL-6 levels and increased IL-10 and Foxp3 levels. HWD also promoted the polarization of macrophages from M1 pro-inflammatory phenotype to M2 anti-inflammatory phenotype. In addition, HWD increased the expression levels of BDNF and TrkB in the hippocampus. Administration of the TrkB receptor agonist 7,8-dihydroxyflavone (7,8-DHF) confirmed the mechanism by which HWD activates BDNF/TrkB signaling to ameliorate insomnia. Furthermore, HWD restored gut microbiota richness and diversity and promoted short-chain fatty acid (SCFA) production in insomniac rats. In vitro experiments confirmed that the acetic acid-treated SCFA group could activate the BDNF/TrkB signaling pathway in neuronal cells, further promoting neuronal cell growth. In conclusion, HWD alleviated insomnia by maintaining gut microbiota homeostasis, promoting SCFA production, reducing neuroinflammatory response and microglia activation, and activating BDNF/TrkB signaling pathway.

[Cuiru Keli Improves Postpartum Hypogalactia in Rats Through Secreted Frizzled-Related Protein 2-Wnt/ß-catenin Signaling Pathway]. / 催乳颗粒通过分泌Frizzledç›¸å ³è›‹ç™½2-Wnt/ß-cateninä¿¡å·é€šè·¯æ”¹å–„å¤§é¼ äº§åŽç¼ºä¹³.

Objective: Based on the secreted frizzled-related protein 2 (SFRP2)-Wnt/ß-catenin signaling pathway, this study explored the effect and mechanism of Cuiru Keli (CRKL) in the treatment of postpartum hypogalactia. Methods: A rat model of postpartum hypogalactia was established by gavaging 2 mL of 1.6 mg/mL bromocriptine mesylate to female rats on the third day after delivery. Female rats with a delivery time difference of less than 48 hours were selected and randomly assigned to 7 groups, including a normal group (without any modeling or medication), a model group, a CRKL low-dose group of model group model rats receiving CRKL at the dose of 3 g/kg, a CRKL medium-dose group of model rats receiving CRKL at the dose of 6 g/kg, a CRKL high-dose group of model rats receiving CRKL at the dose of 9 g/kg, a positive drug group of model rats receiving domperidone at the dose of 3 mg/kg, and a negative control (NC) group of model rats receiving normal saline. Each group contained 6 rats. Except for the normal and model groups, the remaining 5 groups were continuously administered with the respective intervention drugs at the specified doses by gavage once a day for 10 days. Changes in the total litter mass of the offspring in the 7 groups within 10 days were measured, and HE staining was performed to identify pathological changes in the mammary tissue (MT). Six groups of rats (excluding the positive control group) were used to observe the pathological changes of eosinophils in pituitary tissue. ELISA was performed to determine the content of prolactin (PRL) in serum, immunohistochemical staining was used to determine the expression of prolactin receptor (PRLR) in MT, and RT-qPCR was used to determine the mRNA expression of genes related to lactation in MT. Network pharmacology and molecular docking were used to study the therapeutic effect and mechanism of CRKL on postpartum hypogalactia, particularly whether it acted through the SFRP2-Wnt/ß-catenin signaling pathway. The mechanism of CRKL treatment was further validated by detecting mRNA (RT-qPCR) and protein expression (Western blot) of related pathway genes. Cell experiments were conducted using primary culture rat mammary epithelial cells (RMEC) from rat MT. RMEC were divided into four groups, including a normal group (primary culture RMEC, untreated), SFRP2 overexpression group (primary cultured RMEC treated with SFRP2 overexpression vector), SFRP2 overexpression+CRKL group (receiving treatment for SFRP2 overexpression group plus 10% drug-containing serum), and negative control group (primary culture RMEC treated with empty vector). The effect of CRKL on the expression of lactation-related genes FASN, CSN2, and GLUT1 mRNA after SFRP2 overexpression was detected by RT-qPCR. Results: In this study, CRKL was administered at a dose of 3 g/kg in the CRKL low-dose group, 6 g/kg in the medium-dose group, and 9 g/kg in the high-dose group (P<0.05 or P<0.01). Compared with the model group, CRKL at all doses significantly increased the total litter weight gain of the offsprings within 10 days (P<0.05 or P<0.01), and effectively increased lactation (P<0.01), the area of mammary lobules, and the size and filling of acinar cavities. CRKL at all doses also increased the number of eosinophils that secreted PRL in the pituitary gland of the postpartum hypogalactia rat model, and increased the content of PRL in the serum (P<0.05 or P<0.01). CRKL promoted the secretion and expression of PRL in postpartum hypogalactic model rats. In addition, it significantly promoted the expression of genes related to milk fat, milk protein, and lactose synthesis in MT (P<0.05 or P<0.01). Network pharmacology predicted that the Wnt signaling pathway might be a key pathway for CRKL in treating postpartum hypogalactia. The molecular docking results showed that related chemical components in CRKL had good binding ability with CCND1 and SFRP2. Compared with the model group, CRKL at all doses inhibited the expression of SFRP2 gene in vivo (P<0.01) and activated the mRNA and protein expression of CCND1 and c-Myc in the Wnt/ß-catenin signaling pathway in MT (P<0.05 or P<0.01). Cell experiments showed that, compared to the normal group, SFRP2 overexpression reduced the mRNA expression of milk synthesis-related genes FASN, CSN2, and GLUT1 in RMEC (P<0.01). The CCK8 results indicated that 10% of the drug-containing serum was the effective concentration administered to cells (P<0.01). After administering drug-containing serum, the expression of the lactation-related genes FASN, CSN2, and GLUT1 were up-regulated (compared with the SFRP2 overexpression group, P<0.01). Conclusion: CRKL alleviates postpartum hypogalactia through the SFRP2-Wnt/ß-catenin signaling pathway. SFRP2 might be a potential new target for the diagnosis and treatment of postpartum hypogalactia. This reveals a new mechanism of CRKL in treating postpartum hypogalactia and promotes its clinical application.

Effectiveness of Electroacupuncture for Managing Urinary Retention Post Lumbar Spine Surgery: a retrospective single-cohort study.

Objectives: Post-operative urinary retention (POUR) is a frequent complication following surgical procedures, characterized by an acute inability to void, leading to additional complications and extended hospitalization. Acupuncture has been shown to be effective in facilitating spontaneous urination and alleviating anxiety in patients experiencing poor urination. The present study aims to evaluate the effectiveness of electroacupuncture in the management of POUR in patients who have undergone lumbar spine surgery. Methods: This retrospective study conducted at the National Hospital of Acupuncture in Vietnam and reviewed the medical records of patients over 18 years old who underwent lumbar spine surgery and were diagnosed with POUR between January to December 2019. Electroacupuncture was administered at five specific acupuncture points Qugu (CV2), Zhongji (CV3), Zhibian (BL54), Pangguanshu (BL28), and Kunlun (BL60). This study monitored key parameters related to the effectiveness of the acupuncture treatment, including the number of acupuncture treatment sessions required until a patient was successfully treated was recorded, with a maximum of three acupuncture treatment sessions per patient, the time elapsed until urination following the treatment (minutes), and urinary bladder volume before and after treatment (mL). Results: The study demonstrated a 93.3% success rate in treating POUR with electroacupuncture. A significant reduction in post-void residual volume was noted, and patients could void within 30 minutes post-treatment. No significant differences in treatment effectiveness were observed across difference genders and age groups. Conclusion: Electroacupuncture proved to be a highly effective treatment for POUR in patients post-lumbar spine surgery, with a rapid response time and substantial reduction in PVR. However, the retrospective nature of the study and single-center focus limit its generalizability. Future research incorporating randomized controlled trials or multi-center observational studies are recommended to validate these findings and explore the potential of acupuncture in POUR management on a broader scale.

Pityriasis Rosea-Like Eruption following anti-fatigue traditional herbs: Aconitum carmichaelii Debx and Panax Ginseng suspected.

Traditional herbs have a history of clinical use in anti-fatigue. However, several adverse effects of herbs have been identified. Pityriasis rosea-like eruption (PR-LE) is a rare cutaneous complication of herbs. To the best of our knowledge, there have been few reports of PR-LE following herbs. Here, we described a case of PR-LE that developed 6 days after taking anti-fatigue herbs. After the 17 days of stopping Aconitum carmichaelii Debx and Panax Ginseng, it notably faded. So, when anti-fatigue herbs being authorized for fatigue use, monitoring for potential adverse effects is necessary.

Application of artificial intelligence combined with near infrared spectroscopy in the continuous counter-current extraction process of Angelica dahurica formula granules.

The establishment of near infrared (NIR) spectroscopy model mostly relies on chemometrics, and spectral analysis combined with artificial intelligence (AI) provides a new way of thinking for pharmaceutical quality inspection, new algorithms such as back propagation artificial neural networks (BP-ANN) and swarm intelligence optimization algorithms such as sparrow search algorithm (SSA) provide core technical support. In order to explore the application of AI in the pharmaceutical field, in this study, Angelica dahurica formula granules with a relatively complex system were selected as the research object. Quantitative analysis models were established by using partial least squares regression (PLSR) with a micro-NIR spectrometer, and BP-ANN modeling results were compared. For the best PLSR models of six characteristic components in the continuous counter-current extract of Angelica dahurica, R2v of imperatorin was lower than 0.90, and the RPD values of imperatorin, phellopterin, and isoimperatorin were even lower than 1. When the prediction model established by SSA-BP-ANN was used for quantitative analysis, R2v of six components were all higher than 0.92, and the RPD values all higher than 1.5, which proved that the BP-ANN method was better than PLSR. This study confirmed that in the continuous counter-current extraction progress of Angelica dahurica formula granules, the use of micro-NIR spectrometer combined with AI could realize the rapid prediction of the contents of six characteristic components. The comparison results provided a scientific reference for the process analysis and on-line monitoring in the production process of traditional Chinese medicine by micro-NIR spectrometer combined with AI.

Lingguizhugan Decoction Improved Obesity by Modulating the Gut Microbiota and its Metabolites in Mice.

BACKGROUND: The global obese population is rapidly increasing, urgently requiring the development of effective and safe weight-loss medications. The classic Chinese medicine formulation Lingguizhugan De-coction has exerted a significant anti-obesity effect. However, the underlying mechanism is still unclear. OBJECTIVE: This study aimed to explore the mechanism of LGZGD in the treatment of obesity based on the gut microbiota and its metabolites. METHODS: Three different dosages of LGZGD were gavaged to ob/ob mice for 8 weeks. Body mass and visceral fat mass were evaluated. Additionally, the changes in gut microbiota, fecal and plasma metabolites in mice after LGZGD treatment were analyzed by metagenomics and non-targeted metabolomics. RESULTS: The results demonstrated a significant anti-obesity effect of LGZGD treatment in ob/ob mice. Fur-thermore, the metagenomic analysis revealed that LGZGD reduced the ratio of Firmicutes / Bacteroidetes (F to B) in the gut, restored gut microbiota diversity, and identified 3 enriched KEGG pathways, including energy metabolism, lipid metabolism, and energy production and conversion pathways. Based on non-targeted metab-olomics analysis, 20 key metabolites in the feces and 30 key metabolites in the plasma responding to LGZGD treatment were identified, and the levels of Eicosapentaenoic acid (EPA) and Myristoleic acid (MA) might be the metabolites related to gut microbiota after LGZGD treatment. Their biological functions were mainly re-lated to the metabolism pathway. CONCLUSIONS: These findings suggested that LGZGD had therapeutic potential for obesity. The mechanism of LGZGD alleviating obesity was associated with improving dysbiosis of the gut microbiota. LDZGD affected gut microbiota-derived metabolites of EPA and MA and may act on energy metabolism pathways.

A flexible and dissolving traditional Chinese medicine microneedle patch for sleep-aid intervention.

About a quarter of the world's population suffers from insomnia, and the number of the insomniacs is gradually increasing. However, the current drug therapy and non-drug therapy sleep-aid methods have certain limitations. In general, the sleep-aid effect of drug therapy is better than that of Non-drug therapy, but western medicine may lead to some side effects and drug abuse. Although the side effects of Chinese Herbal Medicine (CHM) are relatively small, making the herbal decoction is complex and time-consuming. Therefore, exploring a novel sleep-aid method is very significant. In this paper, a flexible and dissolving Traditional Chinese Medicine (TCM) microneedle patch is proposed for sleep-aid intervention. The TCM microneedle patch is a micrometer-scale intrusive object, and the herbal extracts are carried by the patch. The materials, design method, and fabrication process of the microneedle patch have been described in detail. Besides, the mechanical characteristics of the microneedle patch, sleep-aid effect evaluation method, and experimental scheme have been presented. Three microneedle tips with radii of 5 µm, 15 µm, and 22 µm are selected for simulation analysis. Abaqus simulation results indicate that the smaller the radius of the microneedle tip, the smaller the piercing force. Considering that the microneedle should easily penetrate the skin without buckling, that is, the piercing force should be larger than the buckling force, thus 15 µm, instead of 5 µm or 22 µm, is more suitable to be adopted as the radius of the microneedle tip. For the microneedle with the radius of 15 µm, the piercing force is 0.033 N, and the difference between the piercing force and buckling force is 0.036 N. Experimental results demonstrate that the fracture force of the microneedle is about 0.29 N, which is far larger than the piercing force and buckling force. The single-lead EEG signals of the frontal lobe are used to evaluate the sleep-aid effect of the TCM microneedle patch. After sleep-aid intervention on the Anmian and Yintang acupoints using the patches, for most subjects, the ratios of the low-frequency brain wave energies to the high-frequency brain wave energies are increased obviously, indicating that the proposed sleep-aid method is effective.

Clinical efficacy of Baijin pills in the treatment of generalized tonic-clonic seizure epilepsy with cognitive impairment.

BACKGROUND: The generalized tonic-clonic seizure (GTCS) is the most usual variety of epileptic seizure. It is mainly characterized by strong body muscle rigidity, loss of consciousness, a disorder of plant neurofunction, and significant damage to cognitive function. The effect of antiepileptic drugs on cognition should also be considered. At present, there is no effective treatment for patients with epilepsy, but traditional Chinese medicine has shown a significant effect on chronic disease with fewer harmful side effects and should, therefore, be considered for the therapy means of epilepsy with cognitive dysfunction. AIM: To investigate the clinical efficacy of Baijin pills for treating GTCS patients with cognitive impairment. METHODS: This prospective study enrolled patients diagnosed with GTCS between January 2020 and December 2023 and separate them into two groups (experimental and control) using random number table method. The control group was treated with sodium valproate, and the experimental group was Baijin pills and sodium valproate for three months. The frequency and duration of each seizure, the Montreal Cognitive Assessment Scale (MoCA), and the Quality of Life Rating Scale (QOLIE-31) were recorded before and after treatment. RESULTS: There were 85 patients included (42 in the control group and 43 in the experimental group). After treatment, the seizure frequency in the experimental group was significantly reduced (P < 0.05), and seizure duration was shortened (P < 0.01). The total MoCA score in the experimental group significantly increased compared to before treatment (P < 0.01), and the sub-item scores, except naming and abstract generalization ability, significantly increased (P < 0.05), whereas the total MoCA score in the control group significantly decreased after treatment (P < 0.05). The QOLIE-31 score of the experimental group increased significantly after treatment compared to before treatment (P < 0.01). CONCLUSION: Baijin pills have a good clinical effect on epilepsy with cognitive dysfunction.

Jiawei Duhuo Jisheng Mixture Mitigates Osteoarthritis Progression in Rabbits by Inhibiting Inflammation: A Network Pharmacology and Experimental Approach.

BACKGROUND: Knee osteoarthritis (KOA) is a common degenerative joint disease characterized by cartilage degradation, inflammation, and pain. Traditional Chinese Medicine, including JDJM (a herbal formula derived from the renowned Du Huo Ji Sheng Tang), has been used to alleviate symptoms of KOA, but its underlying mechanisms remain unclear. OBJECTIVE: This study aims to elucidate the potential therapeutic mechanisms of JDJM in treating KOA through network pharmacology, weighted gene co-expression network analysis (WGCNA), molecular docking, and experimental validation in animal models. METHODS: The active compounds of JDJM were identified through TCMSP database searches, and their potential targets were predicted using network pharmacology. WGCNA was employed to identify key modules and hub genes associated with KOA. Molecular docking was performed to assess the binding affinities of key compounds to critical inflammatory targets. Molecular dynamics (MD) simulations were used to evaluate the stability of the protein-ligand complexes. An experimental KOA model in rabbits was used to validate the therapeutic effects of JDJM. Histopathological examinations and inflammatory marker analyses were conducted to confirm the findings. RESULTS: Network pharmacology and WGCNA analyses identified 21 key targets and pathways potentially involved in the therapeutic effects of JDJM. Molecular docking results showed that Glyasperin C had the highest docking scores with EGF and IL-1ß, followed by Stigmasterol with IL-6, Myricanone with INS, and Sesamin with VEGFA. MD simulations confirmed the stability of these protein-ligand complexes, indicating strong and stable interactions. In the rabbit KOA model, JDJM treatment significantly improved knee joint morphology and reduced the levels of inflammatory markers, such as IL-6 and TNF-α. Histopathological analysis revealed reduced cartilage degradation and inflammation in the JDJM-treated group compared to controls. CONCLUSION: JDJM exhibits promising anti-inflammatory and cartilage-protective effects, making it a potential therapeutic option for KOA patients. Further experimental and clinical studies are warranted to confirm these findings and translate them into clinical practice.

Product of traditional Chinese medicine longgui yangxinwan protects the human body from altitude sickness damage by reducing oxidative stress and preventing mitochondrial dysfunction. High Alt Med Biol. 00:00-00, 2024. Background: Plateau reaction, caused by high-altitude exposure, results in symptoms like headaches, dyspnea, palpitations, fatigue, shortness of breath, and insomnia due to reduced oxygen levels. Mitochondria are crucial for high-altitude acclimatization as they regulate oxygen metabolism and cellular energy, reducing oxidative stress and maintaining bodily functions. Methods: The study participants were randomly divided into placebo group, Rhodiola group and longgui yangxinwan (Original name: taikong yangxinwan) group, with 20 people in each group. Three groups of subjects were sampled at three time points (PI: pre-intervention; P-D1: high-altitude day 1; P-D7: high-altitude day 7), and blood pressure, blood oxygen, heart rate, hemoglobin, and red blood cell count were measured. The ATP content, mitochondrial DNA copy number, expression of mitochondria-related genes, reactive oxygen species (ROS), glutathione peroxidase (GSH-PX) and malondialdehyde (MDA) levels, and mitochondrial morphology were measured in blood at each time point. Results: Our study results demonstrate that longgui yangxinwan keeps the selected human physiological indicators stable and prevents mitochondrial dysfunction in the high altitude. Mechanically, longgui yangxinwan decreases the level of ROS in human serum, whereas increases the activity of the antioxidant enzyme GSH-PX. At high-altitude day 1 (P-D1) and high-altitude day 7 (P-D7), ROS in the placebo group were 1.5 and 2.2-fold higher than those of the longgui yangxinwan group, respectively. In addition, longgui yangxinwan enhances ATP production capacity, restores the levels of mitochondrial respiratory chain complexes, and effectively maintains mitochondrial morphology and integrity. At P-D1 and P-D7, the ATP levels in the longgui yangxinwan group were 19-fold and 26-fold higher than those in the placebo group, respectively. Conclusions: Our study highlights longgui yangxinwan as a potential drug for protecting humans from high-altitude damage by reducing oxidative stress and preventing mitochondrial dysfunction.

Chromosome genome assembly of the Camphora longepaniculata (Gamble) with PacBio and Hi-C sequencing data.

Introduction: Camphora longepaniculata, a crucial commercial crop and a fundamental component of traditional Chinese medicine, is renowned for its abundant production of volatile terpenoids. However, the lack of available genomic information has hindered pertinent research efforts in the past. Methods: To bridge this gap, the present study aimed to use PacBio HiFi, short-read, and highthroughput chromosome conformation capture sequencing to construct a chromosome-level assembly of the C. longepaniculata genome. Results and discussion: With twelve chromosomes accounting for 99.82% (766.69 Mb) of the final genome assembly, which covered 768.10 Mb, it was very complete. Remarkably, the assembly's contig and scaffold N50 values are exceptional as well-41.12 and 63.78 Mb, respectively-highlighting its excellent quality and intact structure. Furthermore, a total of 39,173 protein-coding genes were predicted, with 38,766 (98.96%) of them being functionally annotated. The completeness of the genome was confirmed by the Benchmarking Universal Single-Copy Ortholog evaluation, which revealed 99.01% of highly conserved plant genes. As the first comprehensive assembly of the C. longepaniculata genome, it provides a crucial starting point for deciphering the complex pathways involved in terpenoid production. Furthermore, this excellent genome serves as a vital resource for upcoming research on the breeding and genetics of C. longepaniculata.

Naoxintong capsule for treating cardiovascular and cerebrovascular diseases: from bench to bedside.

Naoxintong Capsule (NXT), a renowned traditional Chinese medicine (TCM) formulation, has been broadly applied in China for more than 30 years. Over decades, accumulating evidences have proven satisfactory efficacy and safety of NXT in treating cardiovascular and cerebrovascular diseases (CCVD). Studies have been conducted unceasingly, while this growing latest knowledge of NXT has not yet been interpreted properly and summarized comprehensively. Hence, we systematically review the advancements in NXT research, from its chemical constituents, quality control, pharmacokinetics, to its profound pharmacological activities as well as its clinical applications in CCVD. Moreover, we further propose specific challenges for its future perspectives: 1) to precisely clarify bioactivities of single compound in complicated mixtures; 2) to evaluate the pharmacokinetic behaviors of NXT feature components in clinical studies, especially drug-drug interactions in CCVD patients; 3) to explore and validate its multi-target mechanisms by integrating multi-omics technologies; 4) to re-evaluate the safety and efficacy of NXT by carrying out large-scale, multicenter randomized controlled trials. In brief, this review aims to straighten out a paradigm for TCM modernization, which help to contribute NXT as a piece of Chinese Wisdom into the advanced intervention strategy for CCVD therapy.
