Distribution characteristics of immune infiltration and lymphovascular invasion in patients with breast cancer skin recurrence.

BACKGROUND: To assess the distribution characteristics of immune infiltration and lymphovascular invasion in breast cancer skin recurrence patients. METHODS: We retrospectively analyzed the clinicopathological data of patients who underwent radical surgery for primary breast cancer and experienced skin recurrence between January 2001 and April 2019. Immune and lymphovascular biomarkers were quantified in primary breast cancers, skin lesions and visceral metastatic lesions. Differences in biomarkers distribution between matched tissues were statistically analyzed using the Wilcoxon signed-rank test and Kruskal-Wallis one-way ANOVA. RESULTS: A total of 71 female breast cancer patients were reviewed in this study. Our study found that the expression levels of various lymphocyte immune markers in primary tumor specimens were higher than those in skin recurrences. The expression of CD8, CD57 and CD31 in primary breast cancer was higher than those in the skin. Compared to visceral metastatic lesions, D2-40 was highly expressed in the skin, while CD8 tended to decrease. In the skin specimens, the expression of CD8 (P < 0.001), FOXP3 (P = 0.006) and CD68 (P < 0.001) in the intratumoral area was higher, while the expression of CD57 (P < 0.001) was higher in the peritumoral area. Analyzing specimens from the same patient at different time points of skin progression, it was found that the expression of peritumoral CD4 decreased (P = 0.044) as the disease progressed. The low expression of D2-40 and CD163 in the skin lesions suggested a decrease in DFS. CONCLUSION: The immune microenvironment of breast cancer skin recurrence may be in a state of suppression, and this suppression may intensify with disease progression. The pattern of skin recurrence may be more inclined toward lymphatic invasion. Our study provides new insights into the biological behaviors of this disease and its response to immunotherapy.

Glycyrrhizic acid and glycyrrhetinic acid loaded cyclodextrin MOFs with enhanced antibacterial and anti-inflammatory effects for accelerating diabetic wound healing.

A water stable cyclodextrin MOF (Cu-SD) was synthesized with γ-cyclodextrin derivative as organic ligand and Cu2+ as metal center to co-crystallizely load glycyrrhizic acid (GL) and glycyrrhetinic acid (GA). Cu-SD has a high drug loading capacity for GL (499.91 µg/mg) and GA (112.37 µg/mg), and the drug-loaded materials had a controlled release in different meadiums. In addition, Cu-SD and its drug loaded materials demonstrated better inhibiting α-glucosidase activity than the control drug acarbose. Furthermore, Cu-SD presented excellent antibacterial activity, and the antibacterial activity was significantly enhanced after GA and GL being encapsulated by Cu-SD. Moreover, both free and drug-loaded materials had good anti-inflammatory activities, and the anti-inflammatory effects of GL@Cu-SD and GA@Cu-SD were superior to those of their corresponding free drugs. Cu-SD, GL@Cu-SD and GA@Cu-SD demonstrated good biocompatibility and were applied to treat the wounds of diabetic rats. The experimental results showed that GL@Cu-SD and GA@Cu-SD had good promoting effects on the recovery of chronic diabetic wounds by suppressing wound inflammation.

CRISPR screening identifies PRMT1 as a key pro-ferroptotic gene via a two-layer regulatory mechanism.

Ferroptosis is a form of nonapoptotic cell death characterized by iron-dependent peroxidation of polyunsaturated phospholipids. However, much remains unknown about the regulators of ferroptosis. Here, using CRISPR-Cas9-mediated genetic screening, we identify protein arginine methyltransferase 1 (PRMT1) as a crucial promoter of ferroptosis. We find that PRMT1 decreases the expression of solute carrier family 7 member 11 (SLC7A11) to limit the abundance of intracellular glutathione (GSH). Moreover, we show that PRMT1 interacts with ferroptosis suppressor protein 1 (FSP1), a GSH-independent ferroptosis suppressor, to inhibit the membrane localization and enzymatic activity of FSP1 through arginine dimethylation at R316, thus reducing CoQ10H2 content and inducing ferroptosis sensitivity. Importantly, genetic depletion or pharmacological inhibition of PRMT1 in mice prevents ferroptotic events in the liver and improves the overall survival under concanavalin A (ConA) exposure. Hence, our findings suggest that PRMT1 is a key regulator of ferroptosis and a potential target for antiferroptosis therapeutics.

Synergy of a CuO/C3N4 interface and CuO nanoparticles in the ethynylation of formaldehyde for 1,4-butynediol synthesis.

Catalysts made of CuO/Bi2O3 nanoparticles supported on g-C3N4 were synthesized using a MOF-derived strategy. The activation of CuO to CuCCCu species and stabilization of the catalyst were facilitated by the synergistic effect of the CuO/C3N4 interface and CuO nanoparticles, resulting in enhanced catalytic efficacy in the ethynylation of formaldehyde.

Decreased CNNM2 expression in prefrontal cortex affects sensorimotor gating function, cognition, dendritic spine morphogenesis and risk of schizophrenia.

Genome-wide association studies (GWASs) have reported multiple single nucleotide polymorphisms (SNPs) associated with schizophrenia, yet the underlying molecular mechanisms are largely unknown. In this study, we aimed to identify schizophrenia relevant genes showing alterations in mRNA and protein expression associated with risk SNPs at the 10q24.32-33 GWAS locus. We carried out the quantitative trait loci (QTL) and summary data-based Mendelian randomization (SMR) analyses, using the PsychENCODE dorsolateral prefrontal cortex (DLPFC) expression QTL (eQTL) database, as well as the ROSMAP and Banner DLPFC protein QTL (pQTL) datasets. The gene CNNM2 (encoding a magnesium transporter) at 10q24.32-33 was identified to be a robust schizophrenia risk gene, and was highly expressed in human neurons according to single cell RNA-seq (scRNA-seq) data. We further revealed that reduced Cnnm2 in the mPFC of mice led to impaired cognition and compromised sensorimotor gating function, and decreased Cnnm2 in primary cortical neurons altered dendritic spine morphogenesis, confirming the link between CNNM2 and endophenotypes of schizophrenia. Proteomics analyses showed that reduced Cnnm2 level changed expression of proteins associated with neuronal structure and function. Together, these results identify a robust gene in the pathogenesis of schizophrenia.

Redox homeostasis dysregulation in noise-induced hearing loss: oxidative stress and antioxidant treatment.

Noise exposure is an important cause of acquired hearing loss. Studies have found that noise exposure causes dysregulated redox homeostasis in cochlear tissue, which has been recognized as a signature feature of hearing loss. Oxidative stress plays a pivotal role in many diseases via very complex and diverse mechanisms and targets. Reactive oxygen species are products of oxidative stress that exert toxic effects on a variety of physiological activities and are considered significant in noise-induced hearing loss (NIHL). Endogenous cellular antioxidants can directly or indirectly counteract oxidative stress and regulate intracellular redox homeostasis, and exogenous antioxidants can complement and enhance this effect. Therefore, antioxidant therapy is considered a promising direction for NIHL treatment. However, drug experiments have been limited to animal models of NIHL, and these experiments and related observations are difficult to translate in humans; therefore, the mechanisms and true effects of these drugs need to be further analyzed. This review outlines the effects of oxidative stress in NIHL and discusses the main mechanisms and strategies of antioxidant treatment for NIHL.

Genetic analysis of oligo-recurrence breast cancer: correlation with clinical outcomes.

BACKGROUND: We aimed to identify the relationship between the genomic characteristics and clinical outcomes of oligo-metastatic breast cancer. METHODS: Oligo-metastatic breast cancer diagnosed by pathology from January 2001 and August 2019 were reviewed and we matched the poly-metastatic patients based on the clinicopathological features of patients included. Clinicopathological values and data of genomic alterations were collected. Oligo-recurrence (oligo-R) was defined as a situation where disease progression occurred in less than 5 anatomical sites and other anatomic areas still suppressed by the ongoing therapy. RESULTS: A total of 26 breast cancer patients were enrolled in our study, including 14 patients with strict oligo-metastatic disease (oligo-R > 6 months) and 12 with simultaneous poly-metastatic disease. PIK3CA, TP53 and ERBB2 were the most common shared alterations identified in patients included. Based on the median time of oligo-R, we divided the patients with oligo-metastasis into longer oligo-R group (oligo-R > 31.04 months) and shorter oligo-R group (oligo-R ≤ 31.04 months). The analysis of PIK3CA mutation sites showed that H1047R mutation was closely associated with oligo-metastasis, rather than poly-metastasis. H1047R mutation also predicted a better prognosis (oligo-R > 31.04 months) in oligo-metastatic breast cancer. In addition, HER2 positive was more likely to be related to a good outcome in patients with oligo-metastasis. CONCLUSIONS: Through the genetic analysis of samples from oligo-metastasis, we found the prognostic values of PIK3CA H1047R and HER2 in oligo- and poly-metastasis. We improved the stratification of prognosis and provided new insights for biological behaviors of oligo-metastatic breast cancer.

The prognostic significance of skin involvement in breast cancer patients with chest wall recurrence.

PURPOSE: To assess the prognostic significance of skin involvement in breast cancer patients with chest wall recurrence (CWR). METHODS: We retrospectively analyzed the clinicopathological data of breast cancer patients with CWR who were diagnosed pathologically between January 2000 and April 2020. Disease-free survival (DFS) was the time from radical resection for CWR to disease recurrence. Progression-free survival (PFS) was defined as the time from the diagnosis of locally unresectable CWR to the first sign of disease progression. Persistent chest wall progression was defined as three consecutive chest wall progressions with no distant organ involvement. RESULTS: A total of 476 patients with CWR were included in this study. Skin involvement was confirmed in 345 patients. Skin involvement was significantly correlated with a high T stage (p = 0.003), more positive nodes at initial examination (p < 0.001) and lymphovascular invasion (p < 0.001). Kaplan-Meier analysis showed that skin involvement was a predictor of shorter DFS (p < 0.001), including both local disease progression (p < 0.001) and distant disease progression (p = 0.022). Multivariate analysis showed that skin involvement was an independent biomarker for DFS (p = 0.043). Patients with skin involvement were more likely to experience persistent chest wall progression (p = 0.040). After eliminating the potential deviation caused by an insufficient follow-up time, persistent chest wall progression was more likely to be associated with a high N stage (p = 0.002), negative progesterone receptor (PR; p = 0.001) and positive human epidermal growth factor receptor 2 (HER2; p = 0.046) of the primary site, and negative oestrogen receptor (ER; p = 0.027) and PR (p = 0.013) of the chest wall lesion and skin involvement (p = 0.020). CONCLUSION: Skin involvement was a predictor of poor disease control in patients with CWR and was closely related to persistent chest wall progression. We stratified the prognosis of individualized treatment for breast cancer patients with CWR to provide new insights into the biological behaviours of the disease.

Skin involvement is a predictor of poor local disease control in breast cancer patients with CWR and a factor contributing to persistent chest wall progression after CWR. We stratified the prognosis of individualized treatment for breast cancer patients with CWR.

Oxidative stress in pituitary neuroendocrine tumors: Affecting the tumor microenvironment and becoming a new target for pituitary neuroendocrine tumor therapy.

Pituitary adenomas (PAs), or pituitary neuroendocrine tumors (PitNETs), are commonly found in the anterior pituitary gland. Although the majority of PitNETs are benign and stable, several tumors have malignant characteristics. The tumor microenvironment (TME) plays an important role in the process of tumorigenesis and is composed of several types of cells. Various cells in the TME are significantly affected by oxidative stress. It has been reported that immunotherapeutic strategies have good effects in several cancers. However, the clinical potential of immunotherapies in PitNETs has not yet been fully discussed. Oxidative stress can regulate PitNET cells and immune cells in the TME, thus affecting the immune status of the TME of PitNETs. Therefore, modulation of oxidative stress-regulated immune cells using a combination of several agents and the immune system to suppress PitNETs is a promising therapeutic direction. In this review, we systematically analyzed the oxidative stress process within PitNET cells and various immune cells to elucidate the potential value of immunotherapy.

Glucose-Triggered Release of trans-N-p-Coumaroyltyramine from Zeolitic Imidazolate Framework-8 (ZIF8) Modified with Dioscorea opposita Thunb Polysaccharide.

A Dioscorea opposita Thunb polysaccharide (DOP)-modified ZIF8 material was developed in this study, which can be used as a "smart" glucose-responsive carrier to control the slow release of drugs. The 3-aminophenylboronic acid (APBA) functionalized carboxylated long-chain polymer poly(ethylene glycol) (PEG) segments, which were first modified on the surface of ZIF8 nanoparticles with a hydrogen bond and then chemically cross-linked with DOP through a borate ester bond, leading to the drugs loaded on ZIF8 being "closed" in PBS but being "open" via taking off the DOP coating in high concentrations of glucose; thus, leakage can be prevented in the drug loaded and a glucose-triggered release can effectively result. Moreover, the materials showed good biocompatibility and the released trans-N-p-coumaroyltyramine (NCT) could work synergistically with the DOP to improve insulin resistance and promote glucose consumption in insulin-resistant HepG2 cells.

The prognostic value and immune microenvironment association of AR in HER2+ nonmetastatic breast cancer.

This study aimed to investigate the prognostic value of AR in HER2+ nonmetastatic breast invasive ductal carcinoma (IDC) and its relationship with the immune microenvironment. HER2+ nonmetastatic breast IDC patients diagnosed by pathology who underwent surgery at Sun Yat-sen University Cancer Center from 2016 to 2017 were included. AR+ and AR- breast IDC samples were matched 1:1 in age, T stage, and N stage for immune infiltration analysis. A total of 554 patients with HER2+ nonmetastatic breast cancer were included in this retrospective study, regardless of HR status. The cut-off value for AR was set at 10%. ER+ (p < 0.001) and PR+ (p < 0.001) were associated with positive AR expression. Kaplan-Meier survival curve analysis suggested that AR was closely correlated with overall survival (OS) (p = 0.001) but not disease-free survival (DFS) (p = 0.051). After eliminating the potential impact caused by HR, AR also predicted longer OS (p = 0.014) and was an independent predictive factor for OS of HER2+HR- nonmetastatic breast IDC patients, as revealed by multivariate analysis (p = 0.036). For AR+ and AR- matched HER2+HR- patients, TILs (p = 0.043) and PD-L1 (p = 0.027) levels were significantly lower in AR+ patients. The strongest negative correlation was observed between AR and PD-L1 (Pearson's r = -0.299, p = 0.001). AR+ status was markedly related to better OS in HER2+HR- nonmetastatic breast cancer patients, while a negative correlation was observed between AR and PD-L1/TILs. We provide new insights into the prognostic value of AR and its association with the immune microenvironment to optimize treatment strategies in HER2+ nonmetastatic breast IDCs.

MAPKAPK5-AS1/miR-515-5p/CAB39 Axis Contributes to Non-small Cell Lung Cancer Cell Proliferation and Migration.

Several studies have elucidated the pivotal function that long noncoding RNAs (lncRNAs) exerted on the initiation and development of various human carcinomas, encompassing non-small cell lung cancer (NSCLC). In spite of the fact that lncRNA MAPKAPK5 antisense RNA 1 (MAPKAPK5-AS1) has already been investigated by researchers and confirmed to play oncogenic roles in colorectal cancer, the underlying regulatory function of MAPKAPK5-AS1 in NSCLC cells still remain unclear. In our research, we found that MAPKAPK5-AS1 was expressed at high levels in NSCLC cells. Biological functional assays unclosed that downregulation of MAPKAPK5-AS1 repressed proliferative and migratory capacities whereas promoted apoptotic level in NSCLC cells. Molecular mechanism experiments confirmed that, in NSCLC cells, MAPKAPK5-AS1 combined with miR-515-5p and negatively modulated miR-515-5p expression level. Besides, calcium-binding protein 39 (CAB39) expression level was verified to be negatively modulated by miR-515-5p whereas positively modulated by MAPKAPK5-AS1 in NSCLC cells. Furthermore, rescued-function assays disclosed that inhibited miR-515-5p expression or overexpressed CAB39 could restore the suppressive influence of MAPKAPK5-AS1 silence on NSCLC progression. In summary, MAPKAPK5-AS1 upregulates CAB39 expression level to facilitate NSCLC progression by sequestering miR-515-5p, providing promising biomarkers for NSCLC treatment.

Current Situation of Diagnosis and Treatment of HER2-Positive Metastatic Breast Cancer Patients in China: A Nationwide Cross-Sectional Survey of Doctors.

BACKGROUND: The Advanced Breast Cancer Alliance conducted a nationwide investigation to understand the current situation of the diagnosis and treatment of human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) patients. METHODS: In 2019, electronic questionnaires including basic information about respondents, characteristics of patients, and the present status of diagnosis and treatment were sent to 495 doctors from 203 medical centers covering 28 provinces. RESULTS: The factors that influenced treatment plans included the disease process, the performance status, and the economic status of patients. Regimens and response to neoadjuvant/adjuvant chemotherapy were important factors in the decision of the first-line treatment. Overall, 54% of doctors retained trastuzumab and replaced chemotherapy drugs in second-line treatment regimens for patients with progression-free survival (PFS) ≥ 6 months in the first-line setting, while 52% of participants chose pyrotinib plus capecitabine for patients with PFS < 6 months. Economic factors played an important role in doctors' decision-making and the varying treatment options for respondents in first-tier, second-tier, and other cities. CONCLUSIONS: This large-scale survey regarding the diagnosis and treatment of HER2-positive MBC patients revealed that clinical decisions made by Chinese doctors followed the guidelines, but their choices were constrained by economic factors.

Ferroptosis in glioma treatment: Current situation, prospects and drug applications.

Ferroptosis is a regulatory form of iron-dependent cell death caused by the accumulation of lipid-based reactive oxygen species (ROS) and differs from apoptosis, pyroptosis, and necrosis. Especially in neoplastic diseases, the susceptibility of tumor cells to ferroptosis affects prognosis and is associated with complex effects. Gliomas are the most common primary intracranial tumors, accounting for disease in 81% of patients with malignant brain tumors. An increasing number of studies have revealed the particular characteristics of iron metabolism in glioma cells. Therefore, agents that target a wide range of molecules involved in ferroptosis may regulate this process and enhance glioma treatment. Here, we review the underlying mechanisms of ferroptosis and summarize the potential therapeutic options for targeting ferroptosis in glioma.

Cryoablation reshapes the immune microenvironment in the distal tumor and enhances the anti-tumor immunity.

As one of the local treatments, cryoablation plays an increasingly important role in the comprehensive treatment of malignant tumors with its advantages of less trauma, high reproducibility, and minimally invasive. Activation of anti-tumor immunity, another characteristic of cryoablation, has attracted more and more attention with the extensive application of immunotherapy. Unfortunately, the mechanism by which cryoablation enhances anti-tumor immunity is still unclear. In this study, we applied a multi-omics approach to investigate the effects of local cryoablation in the distal tumor microenvironment. The results revealed that large amounts of tumor antigens were released post-cryoablation, leading to a sterile inflammatory response in distant tumors. During this period, activated lysosome-related pathways result in over-expression of SNAP23 (Synaptosome associated protein 23) and STXBP2 (Syntaxin binding protein 2), activation of immune effector cells, suppression of the release of immunosuppressive factors, and finally enhancement of anti-tumor immunity, which shows a broad prospect in combined immunotherapy.

TiO2 nanotube immobilised 5-lipoxygenase-mediated screening and isolation of anti-inflammatory active compounds from the leaves of lonicera japonica thunb.

In this work, a highly effective separation approach mediated by 5-Lipoxygenase (5-LOX) was established for screening and isolation of anti-inflammatory ingredients from leaves of Lonicera japonica Thunb. (LLJT). Using 5-LOX immobilised on TiO2 nanotubes as a microreactor, the targeted screening was exploited by combining with HPLC-MS system. Four compounds confirmed as luteolin, luteoside, lonicerin, and isochlorogenic acid C and a fraction (M1) were screened out to be potent inhibitors of 5-LOX. Their anti-inflammatory activities were further investigated and confirmed by RAW 264.7 cells inflammation model and rat foot swelling model. Furthermore, M1 was prepared by MCI GEL CHP20P column chromatography, and further separated by Pre-HPLC. One new compound confirmed to be 5,7,3',4'-tetrahydroxyflavone-7-O-sambubioside was first isolated from LLJT. The results provide a new method for the effective separation of active components derived from natural products.HighlightsA 5-LOX mediated separation method was established for isolation of anti-inflammatory compounds.An anti-inflammatory ingredient was separated by MCI GEL CHP20P column chromatography.One new compound was first isolated from leaves of Lonicera japonica Thunb.5-LOX was immobilised on TiO2 nanotubes and exploited by combining with HPLC-MS system.The anti-inflammatory activity of screened components was evaluated.

Carbon Dots Embedded Hybrid Microgel with Phenylboronic Acid as Monomer for Fluorescent Glucose Sensing and Glucose-Triggered Insulin Release at Physiological pH.

A multifunctional and biocompatible hybrid microgel (poly(VPBA-AAm)-CD) using N, S-doped carbon dots (CDs) and ethylene glycol dimethacrylate (EGDMA) as cross-linking agents, and 4-vinylbenzene boronic acid (VPBA) and acrylamide (AAm) as monomers, was designed in this work. This microgel can be easily prepared by a simple one-pot radical dispersion polymerization of the reactants using a rationally designed hydrogen-bonded complex method. The hybrid microgels were spherical particles with a smooth surface and an average particle size of 234 ± 8 nm. The poly(VPBA-AAm)-CD microgel displayed the glucose-responsive swelling within a clinically concerned range at a physiological pH and could realize the controllable release of insulin. In addition, the release rate of insulin in the hybrid microgel (poly(VPBA-AAm)-CD) could be triggered by glucose concentrations in the solution, and the increasing glucose concentrations can accelerate the insulin release. Further in vitro cytotoxicity studies showed that the microgel had good biocompatibility and no obvious toxicity to the cells. These indicate that the prepared microgel (poly(VPBA-AAm)-CD) may supply a new pattern for the self-regulating therapy of insulin deficiency in diabetes.

A Dioscorea opposita Thunb Polysaccharide-Based Dual-Responsive Hydrogel for Insulin Controlled Release.

A novel hydrogel (DOP/PEI-PBA) based on the "three-component" reaction of 2-formylphenylboric acid (2-FPBA), the primary amine group of polyethyleneimine (PEI) and the cis-o-dihydroxy groups of Dioscorea opposita Thunb polysaccharide (DOP) was designed in this work. The hydrogel can be easily prepared by simply mixing the three reactants at room temperature. The hydrogel had dual responsiveness to glucose and pH, and can realize the controllable release of insulin. Moreover, the hydrogel combining insulin and DOP can inhibit the reactive oxygen species (ROS) level and malondialdehyde (MDA) content, and promote glucose consumption as well as the level of superoxide dismutase (SOD), in high-glucose-induced injury in HL-7702 cells, which reflects the synergistic effect of insulin and DOP to protect hepatocytes from oxidative stress at the same time. Further in vitro cytotoxicity studies showed that the hydrogel had good biocompatibility and no obvious toxicity to cells. These indicate that the prepared hydrogel (DOP/PEI-PBA) can be expected to be applied in the clinical treatment of insulin deficiency in diabetes.

SIX5-activated LINC01468 promotes lung adenocarcinoma progression by recruiting SERBP1 to regulate SERPINE1 mRNA stability and recruiting USP5 to facilitate PAI1 protein deubiquitylation.

Increasing research has uncovered the involvement of long noncoding RNAs (lncRNAs) in the progression of multiple cancers including lung adenocarcinoma (LUAD). RT-qPCR and western blot were done to measure RNAs and proteins. Functional assays assessed LUAD cell biological behaviors under knockdown or overexpression of LINC01468, SIX5, SERBP1 or SERPINE1, and the specific function of those genes in regulating LUAD progression was evaluated via animal experiments. Supported by bioinformatics analysis, the interaction among genes was verified via mechanism assays. Upregulation of LINC01468 in LUAD tissues and cells as well as its association with poor clinical outcome was predicted. LINC01468, transcriptionally activated by SIX5, could strengthen proliferative, migratory and invasive abilities of LUAD cells. The oncogenic role of LINC01468 was further validated via animal experiments. SIX5 was a positive transcription regulator of LINC01468 and could exacerbate LUAD cell malignant behaviors. LINC01468 could recruit SERBP1 to enhance SERPINE1 mRNA stability and interact with USP5 to affect PAI1 protein ubiquitination. The oncogenic role of SERBP1 and SERPINE1 was also confirmed. Rescue experiments finally verified LINC01468 modulated proliferation, migration and invasion of LUAD cells via upregulation of SERPINE1. Our observations could contribute to deeper understanding of LUAD.

Immediate effects of neuromuscular joint-facilitation bridging exercises on walking ability and balance function in stroke patients.

[Purpose] This study aimed to examine the immediate effects of a pelvic neuromuscular joint-facilitation intervention on the walking and balance ability of patients with hemiplegia caused by cerebrovascular accidents. [Participants and Methods] A total of 15 patients with hemiplegia caused by cerebrovascular accidents underwent a neuromuscular joint-facilitation lumbar-pattern intervention (intervention group), a bridge exercise (bridge intervention group), or a neuromuscular joint-facilitation bridge intervention (neuromuscular joint-facilitation bridge group). Each intervention was randomly administered at 7-day intervals. Measurement items included the timed up-and-go test, functional reach test, 10-m maximum walking speed test, and load in the standing position. Measurements were taken before and after the intervention in each group. [Results] The timed up-and-go test result was significantly shorter in the neuromuscular joint-facilitation intervention group. Timed up-and-go test results, functional reach, 10-m walking time, and standing load (non-paralyzed side) significantly improved in the neuromuscular joint-facilitation bridge group. [Conclusion] The neuromuscular joint-facilitation bridge intervention was immediately effective in patients with hemiplegia caused by cerebrovascular accidents and improved their walking and balance ability.
