Transcutaneous electrical acupoint stimulation for rehabilitation after total knee arthroplasty: a systematic review and meta-analysis.

BACKGROUND: Rehabilitation after total knee arthroplasty (TKA) has become an indispensable part of the treatment strategy for degenerative joint disease. Despite some current research demonstrating efficacy of transcutaneous electrical acupoint stimulation (TEAS) for post-TKA rehabilitation, the evidence is not conclusive. OBJECTIVE: To systematically assess the evidence supporting TEAS for rehabilitation after TKA. METHODS: A literature search of the PubMed, Embase, The Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database, Wanfang, and Chinese Scientific Journal Data databases for relevant studies published up to October 16, 2023, was performed. Main indicators included visual analog scale (VAS) and functional scores; secondary indicators included range of motion (ROM), interleukin-6 (IL-6) and C-reactive protein (CRP) levels, and analgesia-related adverse events. Risk of bias was evaluated using the Cochrane Tool, and meta-analysis was performed using Review Manager version 5.4. RESULTS: Twenty RCTs with 1295 participants were included. TEAS improved several outcomes compared to control groups. The TEAS group had significantly greater pain reduction at postoperative 6 h, 12 h, 24 h, 48 h, 72 h, 7 days, and 14 days. Moreover, TEAS significantly improved the Hospital for Special Surgery Knee Score, Knee Society Score, and ROM. Patients who underwent TEAS exhibited a lower incidence of analgesia-related adverse events and lower IL-6 and CRP levels. CONCLUSIONS: Available evidence indicates that the application of TEAS in patients undergoing TKA is related to postoperative pain alleviation, functional improvement, and fewer adverse events associated with analgesia.

Efficacy and safety of Osteoking on fracture healing: a systematic review and meta-analysis.

Background: Osteoking (OK) is prescribed in traditional Chinese medicine to accelerate fracture healing. Although some studies suggest the potential efficacy of OK for fracture healing, the evidence remains inconclusive. Aim: To systematically evaluate the safety of OK and its effect on fracture healing. Methods: Relevant authoritative databases were searched until 25 August 2023. Randomized controlled trials (RCTs) of patients with fractures treated with Osteoking were included. We evaluated the risk of bias using the Cochrane tool and performed a meta-analysis using the Review Manager 5.4 software package. Results: 13 studies involving 1123 participants were included. This meta-analysis showed that compared with observations in the control group, the OK group showed a shortened fracture healing time, increased fracture healing rate, reduced swelling regression time and ecchymosis regression time, and improved bone metabolism. In addition, the included studies did not report any serious side effects associated with the use of OK, and the mild side effects resolved without treatment. Conclusion: OK therapy is beneficial and safe for accelerating fracture healing, reducing swelling, eliminating ecchymosis, and improving bone metabolism. However, the meta-analysis results do not support OK treatment for improving the fracture healing rate at all fracture sites and reducing pain across all fracture sites. Further original, high-quality studies are needed to validate these findings.Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=452430, identifier CRD42023452430.

Comparison of the coverage and rotation of asymmetrical and symmetrical tibial components: a systematic review and meta-analysis.

BACKGROUND: An optimized fit of the tibial component to the resection platform and correct rotational alignment are critical for successful total knee arthroplasty (TKA). However, there remains controversy regarding the superiority of symmetric tibial component versus asymmetric tibial component. The objective of this systematic review and meta-analysis was to evaluate the current evidence for comparing the coverage and rotation of asymmetrical and symmetrical tibial component. METHODS: We searched potentially relevant studies form PubMed, Web of science, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and China National Knowledge Infrastructure (CNKI), up to 1 March 2023. Data extraction and quality assessment were performed by two independent reviewers. Meta-analysis was conducted using Review Manager 5.4. RESULTS: Sixteen articles were identified. Compared to symmetric tibial component, asymmetric tibial component increased the coverage of the proximal tibial cut surface (MD, -2.87; 95%CI, -3.45 to -2.28; P < 0.00001), improved the prevalence of tibial baseplate underhang (OR, 0.16; 95%CI, 0.07 to 0.33; P < 0.00001) and malrotation (OR, 0.13; 95%CI, 0.02 to 0.90; P = 0.04), and reduced the degree of tibial component rotation (MD, -3.11; 95%CI, -5.76 to -0.47; P = 0.02). But there was no statistical significance for improving tibial baseplate overhang (OR, 0.58; 95%CI, 0.08 to 3.97; P = 0.58). Additionally, no revision had occurred for the two tibial components in the included studies. CONCLUSION: The current evidence shows asymmetric tibial component offer advantages in terms of coverage and rotation compared with symmetric tibial component in TKA.

Circadian Rhythms in Cardiovascular Function: Implications for Cardiac Diseases and Therapeutic Opportunities.

Circadian rhythms are internal 24-h intrinsic oscillations that are present in essentially all mammalian cells and can influence numerous biological processes. Cardiac function is known to exhibit a circadian rhythm and is strongly affected by the day/night cycle. Many cardiovascular variables, including heart rate, heart rate variability (HRV), electrocardiogram (ECG) waveforms, endothelial cell function, and blood pressure, demonstrate robust circadian rhythms. Many experiential and clinical studies have highlighted that disruptions in circadian rhythms can ultimately lead to maladaptive cardiac function. Factors that disrupt the circadian rhythm, including shift work, global travel, and sleep disorders, may consequently enhance the risk of cardiovascular diseases. Some cardiac diseases appear to occur at particular times of the day or night; therefore, targeting the disease at particular times of day may improve the clinical outcome. The objective of this review is to unravel the relationship between circadian rhythms and cardiovascular health. By understanding this intricate interplay, we aim to reveal the potential risks of circadian disruption and discuss the emerging therapeutic strategies, specifically those targeting circadian rhythms. In this review, we explore the important role of circadian rhythms in cardiovascular physiology and highlight the role they play in cardiac dysfunction such as ventricular hypertrophy, arrhythmia, diabetes, and myocardial infarction. Finally, we review potential translational treatments aimed at circadian rhythms. These treatments offer an innovative approach to enhancing the existing approaches for managing and treating heart-related conditions, while also opening new avenues for therapeutic development.

Effects of methotrexate combined with tocilizumab on growth and bone metabolism in children with juvenile idiopathic arthritis.

OBJECTIVE: This study was designed to determine the effects of methotrexate combined with tocilizumab on growth and bone metabolism in children with juvenile idiopathic arthritis (JIA). METHODS: The medical records of 112 children with JIA treated in the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from March 2019 to June 2021 were collected and analyzed retrospectively. There were 51 patients treated with methotrexate alone who were assigned to the control group. The remaining 61 patients treated with methotrexate combined with tocilizumab were assigned to the observation group. The efficacy, adverse reactions, and growth after the treatment were compared between the two groups. A multiple variable logistic regression analysis was performed to analyze the independent risk factors affecting the efficacy on children. RESULTS: The observation group had significantly better improvement rates of Pediatric American College of Rheumatology Criteria (ACR) Ped 50 and ACR Ped 70 than the control group (P<0.05). The incidence of adverse reactions in the two groups was not significantly different (P>0.05). After therapy, the observation group showed significantly lower C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels than the control group (P<0.001). Significantly higher Z values of the height and weight was shown in the observation group compared to the control group (P<0.01). The observation group showed significantly lower levels of receptor activator of nuclear factor κB ligand (RANKL) and ß-collagen degradation products (ß-CTX) than the control group. A significantly lower osteoprotegerin (OPG) level was seen in the observation group when compared to the control group (P<0.001). A multivariate logistic regression analysis showed that a longer course of disease, disease type, and treatment with methotrexate alone were the independent risk factors for the failure to improve the efficacy on patients (P<0.05). CONCLUSION: Methotrexate combined with tocilizumab can deliver good efficacy on children with JIA, quickly alleviate their clinical symptoms and laboratory indicators, and control the disease progress. It is safe because it will not increase the incidence of adverse reactions.

Ginsenoside Rb3 attenuates skin flap ischemia-reperfusion damage by inhibiting STING-IRF3 signaling.

We investigate the protective effect of ginsenoside Rb3 on skin flap microvasculature following ischemia-reperfusion (I/R) injury and its regulatory mechanism. We used a rat model of I/R injury with the right iliolumbar artery and oxidative stress model of human dermal microvascular endothelial cells. The effects of Rb3 on skin flap tissue and endothelial cell survival, STING-IRF3 pathway activation, and endothelial cell adhesion were measured. Following reperfusion, the survival rate of rat perforator flaps in the Rb3-treated group gradually increased with increasing Rb3 concentration. The treatment also reduced the amount of STING protein, phosphorylated IRF3, and P-selectin in skin flap tissue, with this change being most obvious in microvascular endothelial cells. In vitro, activated IRF3 binds to the P-selectin promoter and induces P-selectin expression. Our results suggest that Rb3 plays a role in reducing I/R flap damage through negatively regulating STING-IRF3 activation to limit leukocyte-endothelial cell adhesion.

A total of 125 biomarkers were found by Metabolomics approach, which associated with the development of AA, mainly involved in amino acid metabolism and lipid metabolism. While SWP can reverse the above 12 metabolites changed by AA. Network analysis revealed the synergistic effects of SWP through the 43 crucial pathways, including Sphingolipid signaling pathway, Sphingolipid metabolism, Arginine and proline metabolism, VEGF signaling pathway, Estrogen signaling pathway. Conclusion: The study suggested that SWP is a useful alternative for the treatment of AA induced by CTX + APH. Its potential mechanisms are to improve hematopoietic microenvironment and promote bone marrow hematopoiesis therapies.

GC-MS based metabolomics strategy to distinguish three types of acute pancreatitis.

Acute pancreatitis (AP) is a progressive systemic inflammatory response with high morbidity and high mortality, which is mainly caused by alcohol, bulimia, gallstones and hyperlipidemia. The early diagnosis of different types of AP and further explore potential pathophysiological mechanism of each type of AP is beneficial for optimized treatment strategies and better patient's care. In this study, a metabolomics approach based on gas chromatography-mass spectrometry (GC-MS), and random forests algorithm was established to distinguish biliary acute pancreatitis (BAP), Hyperlipidemia acute pancreatitis (HLAP), and alcoholic acute pancreatitis (AAP), from healthy controls. The classification accuracies for BAP, HLAP, and AAP patients compared with healthy control, were 0.886, 0.906 and 0.857, respectively, by using 5-fold cross-validation method. And some special metabolites for each type of AP were discovered, such as l-Lactic acid, (R)-3-Hydroxybutyric acid, Phosphoric acid, Glycine, Erythronic acid, l-Phenylalanine, d-Galactose, l-Tyrosine, Arachidonic acid, Glycerol 1-hexadecanoate. Furthermore, associations between these metabolites with the metabolism of amino acids, fatty acids were identified. Our studies have illuminated the biomarkers and physiological mechanism of disease in a clinical setting, which suggested that metabolomics is a valuable tool for identifying the molecular mechanisms that are involved in the etiology of BAP, AAP, HLAP and thus novel therapeutic targets.
