Acupoint Application Combined with Acupressure as an Adjunctive Therapy for Chemotherapy-induced Nausea and Vomiting.

Chemotherapy-induced nausea and vomiting (CINV) refers to the nausea and vomiting experienced by patients after the application of chemotherapy drugs, significantly affecting their quality of life and physical recovery, as well as increasing the pain of the patients. Basic medicine primarily focuses on acid suppression, gastric protection, and vomiting suppression, but there are still many patients with nausea and vomiting symptoms that cannot be alleviated. Traditional Chinese medicine (TCM) can effectively alleviate nausea and vomiting through acupoint stimulation and pressure, while also offering advantages such as simplicity, affordability, and fewer side effects. The aim of this article is to introduce the method of using acupoint application combined with acupressure as an adjunctive therapy for CINV, using the Multinational Association of Supportive Care in Cancer (MASCC) Antiemesis Tool (MAT) tablet scale as a questionnaire. The article details aspects such as acupoint selection, production, and the use of acupoint application, massage techniques, and operating procedures, all with the goal of ensuring the safety and efficacy of acupoint application combined with acupressure as an adjuvant therapy, thereby improving patients' clinical symptoms and quality of life.

Predictors of mortality in patients with isolated gastrointestinal perforation.

Gastrointestinal (GI) perforation is common in the emergency department and has a high mortality rate. The present study aimed to identify risk factors for mortality in patients with GI perforation. The objective was to assess and prognosticate the surgical outcomes of patients, aiming to ascertain the efficacy of the procedure for individual patients. A retrospective cohort study of patients with GI perforation who underwent surgery in a public tertiary hospital in China from January 2012 to June 2022 was performed. Demographics, clinical characteristics, laboratory and imaging results, and outcomes were collected from electronic medical records. The primary outcome measure was in-hospital mortality, and patients were divided into survivor and non-survivor groups based on this measure. Univariate and multivariable logistic regression analyses were performed to obtain independent factors associated with mortality. A total of 529 patients with GI perforation were eligible for inclusion. The in-hospital mortality rate after emergency surgery was 10.59%. The median age of the patients was 60 years (interquartile range, 44-72 years). Multivariable logistic regression analysis indicated that age, shock on admission, elevated serum creatinine (sCr) and white blood cell (WBC) count <3.5x109 or >20x109 cells/l were predictors of in-hospital mortality. In conclusion, advanced age, shock on admission, elevated sCr levels and significantly abnormal WBC count are associated with higher in-hospital mortality following emergency laparotomy.

Atrophic gastritis rather than Helicobacter pylori infection can be an independent risk factor of colorectal polyps: a retrospective study in China.

BACKGROUND: Colonoscopy is considered the most effective screening method for colorectal polyps. However, the longevity and complexity of the procedure makes it less desirable to screen for colorectal polyps in the general population. Therefore, it is essential to identify other independent risk factors. In this study, we explored the link between Hp infection, atrophic gastritis, and colorectal polyps to identify a new potential risk factors of colorectal polyps. METHODS: In this study, atrophic gastritis and intestinal polyps were diagnosed by endoscopy and pathology. All the 792 patients in this retrospective study were divided into sub-groups based on the presence of colorectal polyps. The correlation between polyps and atrophic gastritis was analyzed using the chi-square test and Kruskal-Wallis test. The receiver operating characteristic (ROC) curve was used to compare the predictive value for colorectal polyps between Hp infection and atrophic gastritis. Binary logistic regression was utilized to identify independent risk factors for colorectal polyps. RESULTS: Patients with colorectal polyps were primarily male with advanced age, and the number of patients with colorectal polyps had a higher association with smoking, alcohol drinking, and Hp infection than the control group. A positive correlation between the number of colorectal polyps and the severity of atrophic gastritis was observed. ROC analysis showed that atrophic gastritis was a better risk factors for colorectal polyps. Multivariate analysis identified atrophic gastritis as an independent risk factor for colorectal polyps (OR 2.294; 95% CI 1.597-3.296). CONCLUSIONS: Atrophic gastritis confirmed could be an independent risk factors for colorectal polyps.

Ferroptosis in pancreatic diseases: potential opportunities and challenges that require attention.

The pancreas is an abdominal organ with both endocrine and exocrine functions, and patients with pancreatic diseases suffer tremendously. The regulated cell death of various cells in the pancreas is thought to play a key role in disease development. As one of the newly discovered regulated cell death modalities, ferroptosis has the potential for therapeutic applications in the study of multiple diseases. Ferroptosis has been observed in several pancreatic diseases, but its role in pancreatic diseases has not been systematically elucidated or reviewed. Understanding the occurrence of ferroptosis in various pancreatic diseases after damage to the different cell types is crucial in determining disease progression, evaluating targeted therapies, and predicting disease prognosis. Herein, we summarize the research progress associated with ferroptosis in four common pancreatic diseases, namely acute pancreatitis, chronic pancreatitis, pancreatic ductal adenocarcinoma, and diabetes mellitus. Furthermore, the elucidation of ferroptosis in rare pancreatic diseases may provide sociological benefits in the future.

Magnetic resonance imaging thicknesses and apparent diffusion coefficient values of the endometrium and junction zone in women of reproductive age.

BACKGROUND: The endometrium and uterine junction zone often change throughout the menstrual cycle. Some pathological conditions may appear normal in uterine imaging, which will lead to missed diagnosis and misdiagnosis. PURPOSE: To evaluate the changes in the thickness and apparent diffusion coefficient (ADC) values of the endometrium and uterine junction zone throughout the menstrual cycle in magnetic resonance imaging (MRI) of women of reproductive age. MATERIAL AND METHODS: Data were collected from 40 healthy women of reproductive age with regular menstrual cycles from January 2017 to April 2018. They underwent four total MRI sessions during the menstrual, proliferation, and early and late secretive phases. The main MRI sequences were T2-weighted (T2W) volume isotropic turbo spin echo acquisition (VISTA) spectral attenuated inversion recovery (SPAIR) and diffusion-weighted imaging (b = 0, 600, 800, 1000 s/mm2), which were used to measure the thicknesses and ADC values of endometrium and uterine junction zone. RESULTS: First, the endometrium was thinnest during the menstrual phase and thickest in the late secretive phase. Second, the uterine junction zone was thinnest in the late secretive phase and thickest in the menstrual phase. Third, the ADC values of the endometrium were lowest in the menstrual phase and peaked in the early secretive phase. Finally, the ADC values of the uterine junction zone were lowest in the menstrual phase and peaked in the late secretive phase. CONCLUSION: The endometrium and uterine junction zone showed cyclic changes. Radiologists should consider these changes in the thickness and ADC values when analyzing MRI images of the uterus.

EBV-microRNAs as Potential Biomarkers in EBV-Related Fever: A Narrative Review.

At present, timely and accurate diagnosis and effective treatment of Epstein-Barr Virus (EBV) infection-associated fever remain a difficult challenge. EBV encodes 44 mature microRNAs (miRNAs) that inhibit viral lysis, adjust inflammatory response, regulate cellular apoptosis, promote tumor genesis and metastasis, and regulate tumor cell metabolism. Herein, we have collected the specific expression data of EBV-miRNAs in EBV-related fevers [including infectious mononucleosis (IM), EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH), chronic active EBV infection (CAEBV), and EBV-related tumors] and proposed the potential value of EBV-miRNAs as biomarkers to assist in the identification, diagnosis, and prognosis of EBV-related fever, as well as therapeutic targets for drug development.

The Prognostic Value of Microvascular Density in Early Postoperative Recurrence and Metastasis of T1 Esophageal Squamous Cell Carcinoma.

OBJECTIVE: To identify the relation of microvascular density (MVD) to the early postoperative recurrence and metastasis of T1 esophageal squamous cell carcinoma, and to determine whether MVD could be a prognostic predictor of esophageal squamous cell carcinoma. METHODS: Patients with T1 esophageal squamous cell carcinoma were enrolled. Immunohistochemistry with primary antibody against CD-34 was performed to count MVD. ROC curve was plotted and appropriate cutoff value was determined to evaluate the potential power of MVD in predicting early recurrence and metastasis of T1 esophageal squamous cell carcinoma. Survival curves were drawn by the Kaplan-Meier method and significance were tested by the Mantel-Cox test. RESULTS: A total of 37 patients with T1 esophageal squamous cell carcinoma were enrolled. The MVD of T1 esophageal squamous cell carcinoma patients with early metastasis was significantly higher than that of T1 esophageal squamous cell carcinoma patients without early metastasis (65.83±4.39 vs. 42.26±2.34, p<0.001). MVD was available in distinguishing whether patients with early esophageal are prone to postoperative recurrence or metastasis (AUC=0.861; 95% CI 0.738-0.984, p<0.001), with 88.89% sensitivity and 68.42% specificity of MVD being obtained when the cut-off is 44.5. Kaplan-Meier survival curves showed that patients with a higher MVD had a lower survival (37.35 months) compared with those with low MVD (40.79 months) (p<0.05). CONCLUSIONS: MVD could be a promising indicator for early postoperative recurrence and metastasis of T1 esophageal squamous cell carcinoma and the prognosis of these patients.

Efficacy of phospholipid complex of flavonoids from persimmon leaves on atherosclerosis, and possible mechanism.

OBJECTIVE: To investigate the efficacy of phospholipid complex of flavonoids from persimmon leaves (PLF-PC) on atherosclerosis, and to study its mechanism behind the action. METHODS: To clarify the constituents of the flavonoids from persimmon leaves (PLF), an ultra-performance liquid chromatography/quadrupole-time-of-flight mass spectrometry method was established. To enhance the anti-atherosclerotic effect of PLF, a newly emerging approach based on the combination of phospholipid complexation technique was employed. PLF-PC was prepared by the solvent-evaporation method then characterized using Fourier transform infrared spectroscopy, Powder X-Ray Diffractometry and Scanning electron microscopy. A model of oxidized low-density lipoprotein-induced injury on human umbilical vein endothelial cells was established to investigate the anti-atherosclerotic effect of PLF-PC versus PLF. The levels of nitric oxide, endothelial nitric oxide synthase, intracellular adhesion molecule-1, reactive oxygen species, superoxide dismutase, tumor necrosis factor-αand nuclear factor-κB were observed assay kits. RESULTS: A total of 31 compounds were identified in PLF. PLF-PC showed better anti-atherosclerotic power compared with PLF, moreover, enzyme linked immune-osorbent assay analysis showed that the PLF-PC may effect on endothelial dysfunction and atherosclerosis antioxidant-related mechanisms. CONCLUSIONS: Our findings elucidated that PLF-PC significantly enhanced the PLF's efficacy on atherosclerosis.

FGF2 is overexpressed in asthma and promotes airway inflammation through the FGFR/MAPK/NF-κB pathway in airway epithelial cells.

BACKGROUND: Airway inflammation is the core pathological process of asthma, with the key inflammatory regulators incompletely defined. Recently, fibroblast growth factor 2 (FGF2) has been reported to be an inflammatory regulator; however, its role in asthma remains elusive. This study aimed to investigate the immunomodulatory role of FGF2 in asthma. METHODS: First, FGF2 expression was characterised in clinical asthma samples and the house dust mite (HDM)-induced mouse chronic asthma model. Second, recombinant mouse FGF2 (rm-FGF2) protein was intranasally delivered to determine the effect of FGF2 on airway inflammatory cell infiltration. Third, human airway epithelium-derived A549 cells were stimulated with either HDM or recombinant human interleukin-1ß (IL-1ß) protein combined with or without recombinant human FGF2. IL-1ß-induced IL-6 or IL-8 release levels were determined using enzyme-linked immunosorbent assay, and the involved signalling transduction was explored via Western blotting. RESULTS: Compared with the control groups, the FGF2 protein levels were significantly upregulated in the bronchial epithelium and alveolar areas of clinical asthma samples (6.70 ± 1.79 vs. 16.32 ± 2.40, P = 0.0184; 11.20 ± 2.11 vs. 21.00 ± 3.00, P = 0.033, respectively) and HDM-induced asthmatic mouse lung lysates (1.00 ± 0.15 vs. 5.14 ± 0.42, P < 0.001). Moreover, FGF2 protein abundance was positively correlated with serum total and anti-HDM IgE levels in the HDM-induced chronic asthma model (R2 = 0.857 and 0.783, P = 0.0008 and 0.0043, respectively). Elevated FGF2 protein was mainly expressed in asthmatic bronchial epithelium and alveolar areas and partly co-localised with infiltrated inflammatory cell populations in HDM-induced asthmatic mice. More importantly, intranasal instillation of rm-FGF2 aggravated airway inflammatory cell infiltration (2.45 ± 0.09 vs. 2.88 ± 0.14, P = 0.0288) and recruited more subepithelial neutrophils after HDM challenge [(110.20 ± 29.43) cells/mm2 vs. (238.10 ± 42.77) cells/mm2, P = 0.0392] without affecting serum IgE levels and Th2 cytokine transcription. In A549 cells, FGF2 was upregulated through HDM stimulation and promoted IL-1ß-induced IL-6 or IL-8 release levels (up to 1.41 ± 0.12- or 1.44 ± 0.14-fold change vs. IL-1ß alone groups, P = 0.001 or 0.0344, respectively). The pro-inflammatory effect of FGF2 is likely mediated through the fibroblast growth factor receptor (FGFR)/mitogen-activated protein kinase (MAPK)/nuclear factor kappa B (NF-κB) pathway. CONCLUSION: Our findings suggest that FGF2 is a potential inflammatory modulator in asthma, which can be induced by HDM and acts through the FGFR/MAPK/NF-κB pathway in the airway epithelial cells.

A challenge in soft tissue reconstruction: The use of pedicled anterolateral thigh fasciocutaneous flap and gluteal fasciocutaneous rotational flap in reconstructing a huge full thickness lateral trunk defect.

INTRODUCTION AND IMPORTANCE: Lateral abdominal wall (LAW) defect presents as a rare and unique challenge to the reconstructive surgeons. CASE PRESENTATION: We report a huge recurrent right lateral abdominal DFSP with local invasion in a 35-year-old lady. After wide local excision, the reconstruction was done by using pedicled anterolateral thigh fasciocutaneous flap and gluteal fasciocutaneous rotational flap. CLINICAL DISCUSSION: The goal of reconstruction of the lateral abdominal wall is similar to that of the anterior abdominal wall, namely to provide a static repair that will not attenuate and form a bulge or hernia over time. Anchoring a mesh to stable fixation points is expected to ensure structural integrity in the LAW defect. However, we selected fascial inset from our flaps which did not lead to hernia formation or a bulge following a 7-month postoperative review. In terms of soft tissue coverage, the pedicled anterolateral thigh fasciocutaneous flap and gluteal fasciocutaneous rotational flap were used. The standard free flap will require more complexity of works, especially if the recipient vessels for microsurgical reconstruction are remotely situated or sometimes not even available. CONCLUSION: Huge full-thickness LAW defect following an oncological resection can be reconstructed with combination of simpler locoregional flaps which yield good functional and aesthetic outcome.

Exosomes secreted by chemoresistant ovarian cancer cells promote angiogenesis.

BACKGROUND: Ovarian cancer (OC) has the highest mortality rate in gynecologic tumors. Despite decades of continuous efforts, the survival rate of patients has not improved significantly, mostly due to drug resistance. Exosomes are hot topics in recent years. Cells can affect the biological behaviors of other cells by transferring exosomes. So far, numerous researchers have found that tumor cells can secrete exosomes which play a important role in the development of tumors. Solid tumors can promote angiogenesis. When drug resistance occurs, it seems that more blood vessels form. We suppose that exosomes derived from chemoresistant OC cells can also promote angiogenesis. RESULTS: We investigate whether exosomes secreted by chemoresistant SKOV3-DDP cells (SKOV3-DDP-exo) and sensitive SKOV3 cells (SKOV3-exo) influence angiogenesis. After exosomes were extracted, exosomes were co-cultured with HUVECs. We found that SKOV3-DDP-exo and SKOV3-exo are absorbed by endothelial cells and promote the proliferation, migration, invasion and tube formation of endothelial cells. Moreover, SKOV3-DDP-exo is more powerful in angiogenesis, suggesting that parts of the components of SKOV3-DDP-exo are significantly radical. We also found that miR-130a was highly expressed in drug-resistant OC cells. Also, we found that miR-130a in SKOV3-DDP-exo is higher than SKOV3-exo. Therefore, we suggest that miR-130a in exosomes is the main cause of chemoresistant OC cells promoting angiogenesis.

Effects of ClpP protease on biofilm formation of Enterococcus faecalis

Abstract Enterococcus faecalis (E. faecalis), one of the main pathogens responsible for refractory periapical periodontitis and nosocomial infections, exhibits markedly higher pathogenicity in biofilms. Objectives Studies have shown that caseinolytic protease P (ClpP) is involved in biofilm formation. However, to date, few studies have investigated the role of ClpP in the survival of E. faecalis, and in enhancing biofilm formation. Therefore, we investigated the role of ClpP in the formation of E. faecalis biofilms. Methodology In our study, we used homologous recombination to construct clpP deleted and clpP complement strains of E. faecalis ATCC 29212. A viable colony counting method was used to analyze the growth patterns of E. faecalis. Crystal violet staining (CV) and confocal scanning laser microscopy (CLSM) were used to characterize biofilm mass formation and scanning electron microscopy (SEM) was used to observe the biofilm microstructure. Data was statistically analyzed via Student's t-test or one-way analysis of variance (ANOVA). Results The results exhibited altered growth patterns for the clpP deletion strains and depleted polysaccharide matrix, resulting in reduced biofilm formation capacity compared to the standard strains. Moreover, ClpP was observed to increase biofilm formation in E. faecalis. Conclusion Our study shows that ClpP can increase biofilm formation in E. faecalis and emphasizes the importance of ClpP as a potential target against E. faecalis.

Divided Eyelid Nevus: Surgical Repair Discussion and Case Reports From Northwestern China.

Currently, due to the lack of long-term postoperative follow-up outcomes of the congenital divided eyelid nevus, we described our surgical approaches and presented the functional and cosmetic results of 13 patients with an average of 5-year follow-up. Based on the surgical treatments and the follow-ups, the selection of total or subtotal excision depends on the lesion location and the use of blepharoplasty approaches is determined by defect size. The CO2 laser may be a useful second-stage procedure to ablate remnant lesions, but long-term monitoring is required.

Étant donné le peu de suivi postopératoire à long terme sur les résultats cliniques de la réparation du nævus palpébral congénital en miroir, les chercheurs décrivent les méthodes chirurgicales utilisées et présentent les résultats fonctionnels et esthétiques chez 13 patients, suivis sur une période moyenne de cinq ans. D'après les traitements chirurgicaux et les suivis, le choix d'une excision totale ou partielle dépend du foyer de la lésion, et le mode de blépharoplastie repose sur la dimension de l'anomalie. Le laser CO2 peut être utilisé en deuxième phase pour faire disparaître les vestiges des lésions, mais une surveillance à long terme s'impose.

Long-term PM2.5 exposure increases the risk of non-small cell lung cancer (NSCLC) progression by enhancing interleukin-17a (IL-17a)-regulated proliferation and metastasis.

PM2.5 is a class of airborne particles and droplets with sustained high levels in many developing countries. Epidemiological studies have indicated that PM2.5 is closely associated with the increased morbidity and mortality of lung cancer in the world. Unfortunately, the effects of PM2.5 on lung cancer are largely unknown. In the present study, we attempted to explore the role of PM2.5 in the etiology of NSCLC. Here, we found that long-term PM2.5 exposure led to significant pulmonary injury. Epithelial-mesenchymal transition (EMT) and cancer stem cells (CSC) properties were highly induced by PM2.5 exposure. EMT was evidenced by the significant up-regulation of MMP2, MMP9, TGF-ß1, α-SMA, Fibronectin and Vimentin. Lung cancer progression was associated with the increased expression of Kras, c-Myc, breast cancer resistance protein BCRP (ABCG2), OCT4, SOX2 and Aldh1a1, but the decreased expression of p53 and PTEN. Importantly, mice with IL-17a knockout (IL-17a-/-) showed significantly alleviated lung injury and CSC properties following PM2.5 exposure. Also, IL-17a-/--attenuated tumor growth was recovered in PM2.5-exposed mice injected with recombinant mouse IL-17a, accompanied with significantly restored lung metastasis. Taken together, these data revealed that PM2.5 could promote the progression of lung cancer by enhancing the proliferation and metastasis through IL-17a signaling.

Tumor deposit serves as a prognostic marker in gastric cancer: A propensity score-matched analysis comparing survival outcomes.

BACKGROUND: Gastric cancer (GC) treatment is determined by accurate tumor staging. The value of tumor deposit (TD) in prognostic prediction staging system is not yet determined. METHODS: We retrospectively analyzed clinical information on GC patients who underwent gastrectomy at the Department of General Surgery of the Chinese PLA General Hospital from July 2014 to June 2016. Propensity score matching (PSM) was performed to reduce the possibility of selection bias according to the presence of TD. RESULTS: Of the 1034 GC patients, 240 (23.21%) presented with TD, which was associated with younger age and larger tumor size (all P < .05). TD-positive patients had a worse survival than TD-negative patients before (P < .001) and after (P = .017) matching. Multivariable analysis showed that mortality risk of patients with TD increased by 58%, 62%, 37%, and 40% in the crude (HR = 1.58, 95% CI 1.32-1.89, P < .001), adjusted I (HR = 1.62, 95% CI 1.35-1.94, P < .001), adjusted II (HR = 1.37, 95% CI 1.13-1.66, P = .001), and adjusted III (HR = 1.40, 95% CI 1.16-1.68, P < .001) models before matching. Similarly, in the PSM cohort patients with TD had worse prognosis in the crude (HR = 1.32, 95% CI 1.07-1.63, P = .011), adjusted I (HR = 1.35, 95% CI 1.09-1.67, P = .005), adjusted II (HR = 1.26, 95% CI 1.00-1.58, P = .049), and adjusted III (HR = 1.33, 95% CI 1.07-1.65, P = .010) models. TD had a similar value range between N1 and N2 stages among different models. CONCLUSIONS: Among GC patients, TD is associated with survival and may have a role in the staging of patients.

Seawater Immersion Aggravates Early Mitochondrial Dysfunction and Increases Neuronal Apoptosis After Traumatic Brain Injury.

Traumatic brain injury (TBI) is a major cause of death and disability in naval warfare. Due to the unique physiochemical properties of seawater, immersion in it exacerbates TBI and induces severe neural damage and complications. However, the characteristics and underlying mechanisms of seawater-immersed TBI remain unclear. Mitochondrial dysfunction is a major cause of TBI-associated brain damage because it leads to oxidative stress, decrease in energy production, and apoptosis. Thus, the present study aimed to further elucidate the current understanding of the pathology of seawater-immersed TBI, particularly the role of mitochondrial dysfunction, using a well-defined rat model of fluid percussion injury and a stretch injury model comprising cultured neurons. The biochemical and pathological markers of brain-related and neuronal injuries were evaluated. Histological analysis suggested that seawater immersion enhanced brain tissue injury and induced a significant increase in apoptosis in rats with TBI. Additionally, lactate dehydrogenase release occurred earlier and at higher levels in stretched neurons at 24 h after seawater immersion, which was consistent with more severe morphological changes and enhanced apoptosis. Furthermore, seawater immersion induced more rapid decreases in mitochondrial membrane potential, adenosine triphosphate (ATP) content, and H+-ATPase activity in the cortices of TBI rats. In addition, the immunochemical results revealed that seawater immersion further attenuated mitochondrial function in neurons exposed to stretch injury. The increases in neuronal damage and apoptosis triggered by seawater immersion were positively correlated with mitochondrial dysfunction in both in vivo and in vitro models. Thus, the present findings strengthen the current understanding of seawater-immersed TBI. Moreover, because seawater immersion aggravates mitochondrial dysfunction and contributes to post-traumatic neuronal cell death, it is important to consider mitochondria as a therapeutic target for seawater-immersed TBI.

Mast cell activation, TLR4-NF-κB/TNF-α pathway variation in rats' intestinal ischemia-reperfusion injury and Tongxinluo's therapeutic effect.

This study was designed to investigate mast cell activation and related TLR4-NF-κB/TNF-α pathway variation in 3 and 7 days' rats intestinal I/R injury, and TXL's intervention effect. Rat intestine I/R injury was carried out using superior mesenteric artery occlusion model with 30 min ischemia followed 3 or 7 days' reperfusion. Rats were administered TXL ultrafine power of 0.4, 0.8 and 1.6g/kg/d respectively for 3 or 7 days after modeling. Mast cell activation was determined by immunofluorescent double staining. TLR4, ANGPTL4 and microRNA126 were determined by RT-PCR. PECAM-1, NF-κB p65, TNF-α and VE-Cadherin were determined by immunohistochemical staining. Intestine I/R induced massively mast cell activation and overexpressed TLR4, NF-κB, TNF-α, PECAM-1, miR126 in 3 and 7 days. VE-cadherin and ANGPTL4 expression was reduced. TXL treatment attenuated mast cell activation and inhibited TLR4, NF-κB, TNF-α, PECAM-1 over-expression in 3 and 7 days, protected VE-cadherin and ANGPTL4 protein. Inflammation boomed in rats' intestine I/R injury for 3 and 7 days, characterized by mast cell and related TLR4-NF-κB/TNF-α pathway activation, accompanied with endothelial barrier dysfunction and enhanced vascular permeability. TXL treatment attenuated inflammation, protected endothelial barrier function. TXL treat intestine I/R injury, according with "Treat different diseases with the same method" in TCM theory.

Reliability measure of the rib cage deformity by a postural assessment software in patients with adolescent idiopathic scoliosis / Medida da Confiabilidade da Deformidade da Caixa Torácica por um Software de Avaliação Postural em Pacientes com Escoliose Idiopática do Adolescente

Abstract Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine that generates changes in the biomechanics of the rib cage. Digital photogrammetry enables the recording of subtle changes and the interrelationship between parts of the human body that are difficult to measure by other means. The aim of this study was to create angles and thoracic distances and to evaluate the interobserver and intraobserver reliability of these measurements using the Software de Avaliação Postural (SAPO) in patients with AIS. This cross-sectional study evaluated 30 individuals aged between 11 and 18 years with AIS. We used SAPO with the thoracic markers in the form of angles (A) and distances (D) with involves structures like acromion, manubrium, xiphoid process, lower angle of the scapula, last false rib, anterior iliac spine process. Two experienced observers (A and B) analyzed the photos and all followed the same routine of analysis. Intraobserver and interobserver reproducibility was assessed by the Bland-Altman plot and intraclass correlation coefficient (ICC), while intraobserver and interobserver reliability was assessed by the T-Test and Wilcoxon's Test. A high repeatability index was obtained among the evaluations, with twelve of the sixteen variables considered as reliable in all statistical tests. The interobserver analyzes presented excellent correlation coefficients (ICC), showing good reliability for six of the sixteen variables proposed. The SAPO method presented good reproducibility and reliability for most of the thoracic markers created, showing that photogrammetry may be a complementary tool in the evaluation of thoracic alterations in patients with AIS.

Resumo A escoliose idiopática do adolescente (EIA) é uma deformidade tridimensional da coluna que gera alterações na biomecânica da caixa torácica. A fotogrametria digital permite o registro de mudanças sutis e a inter-relação entre partes do corpo humano que são difíceis de medir por outros meios. Objetivou-se criar ângulos e distâncias torácicas e avaliar a confiabilidade interobservador e intraobservador dessas medidas utilizando o Software de Avaliação Postural (SAPO) em pacientes com EIA. Este estudo transversal avaliou 30 indivíduos com idades entre 11 e 18 anos com EIA. Utilizamos o SAPO com os marcadores torácicos na forma de ângulos (A) e distâncias (D), envolvendo estruturas como: acrômio, manúbrio, processo xifóide, ângulo inferior da escápula, última costela falsa, processo da espinha ilíaca anterior. Dois observadores experientes (A e B) analisaram as fotos e todos seguiram a mesma rotina de análise. A reprodutibilidade intraobservador e interobservador foi avaliada pelo gráfico de Bland-Altman e coeficiente de correlação intraclasse (CCI), enquanto a confiabilidade intraobservador e interobservador foi avaliada pelo Teste T e Teste de Wilcoxon. Um alto índice de repetibilidade foi obtido entre as avaliações, com doze das dezesseis variáveis ​​consideradas confiáveis ​​em todos os testes estatísticos. As análises interobservadores apresentaram excelentes coeficientes de correlação (ICC), mostrando boa confiabilidade para seis das dezesseis variáveis ​​propostas. O método SAPO apresentou boa reprodutibilidade e confiabilidade para a maioria dos marcadores torácicos criados, mostrando que a fotogrametria pode ser uma ferramenta complementar na avaliação de alterações torácicas em pacientes com EIA.
