Temporal evolution of postsurgical bone repair in a rabbit model: A [99mTc]Tc-MDP scintigraphic study

Abstract Bone regeneration is crucial for repairing bone tissue following various injuries. Research techniques that enable the study of metabolic changes in bone tissue under different conditions are important for understanding bone repair and remodeling. This study used bone scintigraphy to evaluate osteogenesis secondary to osteotomy in a preclinical model of New Zealand rabbits. For this purpose, we conducted a longitudinal, prospective, case-control study in which scintigraphic variables were measured in both the right forearm (case-operated) and the left forearm (control - non-operated). The study sample consisted of 10 rabbits subjected to osteotomy, followed by a 12-week postoperative evaluation period, divided into six imaging stages at 1, 2, 3, 4, 8, and 12 weeks. We observed that the operated forearm showed significantly higher external radiation than the control side, using the pinhole collimator, denoting an increase in the biodistribution and tropism of the radiopharmaceutical to the operated forearm. Among the three evaluated time points, osteoblastic activity was highest in the second week and presented a significant decline in the 8th and 12th weeks, denoting regeneration and resolution of the surgical injury; the control forearm was also influenced by the inactivity imposed by the operated forearm. This fact was notably evidenced by the reduction in the metabolic activity of osteoblasts in the left forearm. Our study suggested that bone scintigraphy was sensitive enough to semi-quantitatively differentiate the metabolic activity of osteoblasts in the operated forearm in the three temporal landmarks evaluated in the study.

A Ten-Year Comparative Study on Ethical Cognition of Experimental Animals among Medical Students in a University / 中国医学伦理学

The study was carried out to understand the changes in the ethical cognition status of laboratory animals and the effectiveness of laboratory animal ethics education among medical students in Xiangya School of Medicine of Central South University (CSU), and provide new enlightenment for further strengthening the ethical education of laboratory animals. In the study, the same self-compiled questionnaire was used to investigate the ethical cognition of experimental animals among medical students in Xiangya School of Medicine of CSU in 2011 and 2021, and 359 and 363 questionnaires were collected respectively. Through comparative analysis of the questionnaire results before and after ten years, it was found that medical students’ animal experiment operation and attitudes towards laboratory animals, cognition of experimental animal ethics knowledge and their attitude to animal experiment ethics education were significantly improved. It showed that the state of experimental animal ethics cognition among medical students in Xiangya School of Medicine of CSU had improved significantly in recent 10 years, but the cognition of experimental animal ethics knowledge was higher than the actual behavior of caring for experimental animals, and there was the phenomenon of "separation of knowledge and action". The ethics education of experimental animals needs to pay more attention to the development of students’ behavior of caring for experimental animals.

Total Saponins of Dioscorea Mitigate Nonalcoholic Steatohepatitis in Mice by Regulating AMPK/SREBP-1c/ACC Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the role and mechanism of total saponins of Dioscorea （TSD） in mitigating nonalcoholic steatohepatitis （NASH） in mice. MethodForty-eight C57BL/6J mice were randomized into a normal group and a modeling group. The mice for modeling were fed with a high-fat and high-cholesterol diet + 20% fructose solution for 16 weeks and randomized into model， atorvastatin （4 mg·kg-1·d-1）， and high-， medium-， and low-dose （200， 60， and 20 mg·kg-1·d-1） TSD groups. The mice were administrated with corresponding doses of drugs by gavage for 8 weeks. The mouse activity， liver index， levels of total cholesterol （TC）， triglycerides （TG）， and free fatty acids （FFAs） in the liver， and levels of TC， TG， aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， γ-glutamyl transferase （GGT）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in the serum were measured. Hematoxylin-eosin staining， Masson staining， oil red O staining， and transmission electron microscopy were employed to observe the pathological changes， lipid accumulation， and morphological changes of liver ultrastructure. Western blot was employed to determine the protein levels of AMP-activated protein kinase （AMPK）， sterol regulatory element-binding protein-1c （SREBP-1c）， acetyl-CoA carboxylase （ACC）， and phosphorylated ACC （p-ACC） in the liver tissue. ResultCompared with the normal group, the activity of mice in the model group decreased(P<0.05， P<0.01), the levels of TC, TG, FFA and serum TC, TG, ALT, AST, GGT, IL-1β and TNF-α, liver coefficient and liver pathology scores were significantly increased, the expression of p-AMPK/AMPK and p-ACC proteins in liver tissues was significantly reduced, and the expressions of SREBP-1c and ACC proteins were significantly increased (P<0.01). Compared with the model group， atorvastatin increased the mouse activity （P<0.05）， while each dose of TSD caused no significant changed in the mouse activity. The levels of TC, TG, FFA in liver and serum TC, TG, ALT, AST, GGT, IL-1β, TNF-α, liver coefficient and liver pathological score in TSD and atorvastatin groups were significantly decreased, and the expressions of p-AMPK/AMPK and p-ACC in liver tissue were significantly increased. The expressions of SREBP-1c and ACC were significantly decreased (P<0.05,P<0.01). ConclusionTSD may alleviate NASH in mice by regulating the AMPK/SREBP-1c/ACC signaling pathway to reduce lipid synthesis.

TREM-2 Drives Development of Multiple Sclerosis by Promoting Pathogenic Th17 Polarization / 神经科学通报·英文版

Multiple sclerosis (MS) is a neuroinflammatory demyelinating disease, mediated by pathogenic T helper 17 (Th17) cells. However, the therapeutic effect is accompanied by the fluctuation of the proportion and function of Th17 cells, which prompted us to find the key regulator of Th17 differentiation in MS. Here, we demonstrated that the triggering receptor expressed on myeloid cells 2 (TREM-2), a modulator of pattern recognition receptors on innate immune cells, was highly expressed on pathogenic CD4-positive T lymphocyte (CD4+ T) cells in both patients with MS and experimental autoimmune encephalomyelitis (EAE) mouse models. Conditional knockout of Trem-2 in CD4+ T cells significantly alleviated the disease activity and reduced Th17 cell infiltration, activation, differentiation, and inflammatory cytokine production and secretion in EAE mice. Furthermore, with Trem-2 knockout in vivo experiments and in vitro inhibitor assays, the TREM-2/zeta-chain associated protein kinase 70 (ZAP70)/signal transducer and activator of transcription 3 (STAT3) signal axis was essential for Th17 activation and differentiation in EAE progression. In conclusion, TREM-2 is a key regulator of pathogenic Th17 in EAE mice, and this sheds new light on the potential of this therapeutic target for MS.

Mechanism of Cuscutae Semen to Control Premature Ovarian Failure Based on Lipid and Atherosclerosis Pathways / 中国实验方剂学杂志

ObjectiveThe active ingredients， action targets， and signaling pathways of Cuscutae Semen to control premature ovarian failure were initially predicted by network pharmacology and molecular docking techniques， and an animal model of premature ovarian failure was constructed to explore the mechanism of Cuscutae Semen based on lipid and atherosclerosis signaling pathways. MethodThe effective components and corresponding targets of drugs were obtained from Traditional Chinese Medicines Systems Pharmacology Platform （TCMSP）， Swiss Target Prediction， Pharmmapper， and other databases. GeneCards database was used to collect disease-related targets. Venny2.1.0 online tool was used to screen out the intersection targets of drugs and diseases， and STRING database and Cytoscape v3.7.2 software were used to construct the network diagram of "drug-component-target" and protein-protein interaction （PPI）. The gene ontology （GO） and the Kyoto encyclopedia of genes and genomes （KEGG） enrichment analyses of the intersection targets were performed by running the R language script. The molecular docking technology was utilized to dock drug components with targets and visualize some of the docking results. The mice were randomly divided into a blank group， a model group， a Cuscutae Semen group， and an estradiol valerate group， and the ovarian premature failure model was prepared by chronic stress. The blank group and the model group were gavaged with the same amount of normal saline， and the Cuscutae Semen group was given a Cuscutae Semen decoction of 2.6 g·kg-1·d-1. The estradiol valerate group was given an estradiol valerate solution of 0.13 mg·kg-1·d-1. After four weeks， samples were collected， and hematoxylin-eosin （HE） staining was performed to observe the histopathological changes in the ovary. Serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E2）， Muller's tube inhibitor/anti-Muller's tube hormone （AMH）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） were determined by enzyme-linked immunosorbent assay （ELISA）. The expression levels of extracellular regulatory protein kinase （ERK）， nuclear transcription factor-κB p65 （NF-κB p65）， nuclear transcription factor-κB suppressor α （IκBα）， interleukin-1β （IL-1β）， IL-6， and tumor necrosis factor-α （TNF-α） were measured by Western blot. ResultA total of 171 targets of Cuscutae Semen for the prevention and treatment of premature ovarian failure were screened， mainly including tumor protein p53 （TP53）， protein kinase B1 （Akt1）， sarcoma （SRC）， tumor necrosis factor （TNF）， epidermal growth factor receptor （EGFR）， etc. KEGG pathway enrichment analysis predicts that Cuscutae Semen is mainly involved in lipid and atherosclerosis， TNF signaling pathway， and TP53 signaling pathway to control premature ovarian failure. The animal experiments show that compared with the premature ovarian failure model group， the Cuscutae Semen group can significantly upregulate AMH， E2， and HDL-C （P<0.05， P<0.01）， significantly downregulate LH， TC， and LDL-C （P<0.01）， greatly reduce IL-1β， IL-6， and TNF-α protein levels， as well as ERK， NF-κB p65， and their phosphorylation levels （P<0.01）. ConclusionCuscutae Semen can regulate hormone levels and improve ovarian function through a multi-component， multi-target， and multi-pathway approach， and the mechanism may be related to the regulation of lipid and atherosclerosis signaling pathways.

Effect of Longmu Piyan Prescription on Oxidative Stress in Atopic Dermatitis Mice / 中国实验方剂学杂志

ObjectiveThis study observes the intervention effect of Longmu Piyan prescription on oxidative stress in BALB/c mice with atopic dermatitis （AD） induced by 2，4-dinitrochlorobenzene （DNCB） and explores its mechanism. MethodThe AD model was established using the method of DNCB sensitization on the back skin of BALB/c mice. Forty male BALB/c mice were randomly divided into a blank group， a model group， a vitamin C control group （0.5×10-3 mg·kg-1）， and a Longmu Piyan prescription group （26 g·kg-1）. Except for the blank group， other groups were sensitized with different concentrations of DNCB on the back to induce AD， and the blank group was treated with matrix coating. The gastric administration was started on the seventh day after sensitization with 2% DNCB and on the 24th day after sensitization with 0.2% DNCB continuously for 21 days. The changes in skin lesions of each group were directly observed after the experiment. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of interleukin （IL）-4， tumor necrosis factor （TNF）-α， immunoglobulin E （IgE）， and reactive oxygen species （ROS） in the serum of each group. The total antioxidant capacity determination kit-trace method (ABTS method) was used to measure the level of total antioxidant capacity （TAOC） in serum. The Hematoxylin eosin （HE） staining method was used to observe the pathological and morphological changes of the skin lesion site. The immunohistochemical method was used to detect the expression of thymic stromal lymphopoietin （TSLP） in the skin lesion site. Western blot was used to detect the expression of filaggrin （FLG） in the dorsal skin lesions. ResultThe results showed that compared with the blank group， the skin lesion score of the model group mice was significantly increased （P<0.01）， and HE staining showed characteristic pathological changes of AD in the skin lesion site. At the same time， the expression of TSLP in the skin lesion was significantly increased， and that of FLG was reduced （P<0.05）. The levels of TNF-α， IL-4， IgE， and ROS in serum increased， while the activity of TAOC decreased （P<0.01）. Compared with the model group， the Longmu Piyan prescription group showed a significant decrease in skin lesion scores and a significant improvement in skin lesion pathology. At the same time， the expression of TSLP decreased， and the expression of FLG increased in the skin lesions （P<0.05）. In addition， compared with the model group， the serum levels of TNF-α， IL-4， IgE， and ROS also decreased to varying degrees （P<0.05，P<0.01）， and TAOC activity increased in the Longmu Piyan prescription group （P<0.01）. ConclusionThere is a significant correlation among the degree of oxidative stress， the severity of skin lesions in AD， and the levels of inflammatory cytokines. Longmu Piyandu prescription can improve AD-like skin lesions in BALB/c mice by promoting ROS clearance， enhancing TAOC， and inhibiting oxidative stress， thus protecting the skin barrier and reducing inflammation.

La solidez de la investigación homeopática fundamental / The strength of fundamental homeopathic research

La investigación fundamental en homeopatía ha avanzado considerablemente en los últimos 20 años: desde estudios exploratorios con animales y plantas hasta la caracterización de los efectos sistémicos de los medicamentos homeopáticos y estudios in vitro con sistemas celulares aislados para evaluar los cambios en los mecanismos de adaptación celular y señalización intracelular frente a tratamientos homeopáticos variables. El número de artículos publicados a lo largo del tiempo ha permitido realizar varias revisiones sistemáticas. Recientemente, la demostración de que los medicamentos homeopáticos podrían modificar las funciones celulares a través de mecanismos epigenéticos (metilación y desmetilación de ADN) preparó el camino para un campo de investigación completamente nuevo. En paralelo, el descubrimiento de las nanopartículas y propiedades físicas específicas de las diluciones homeopáticas ha arrojado luz hacia un campo antes poco conocido, dado que se consideraba que las diluciones homeopáticas no consistían más que de agua. Así las cosas, los retos para el futuro conciernen a la demostración, o no, de la interrelación entre ambos fenómenos.

Fundamental research in homeopathy has much advanced in the past 20 years. From exploratory studies with animals and plants to the characterization of the systemic effects of homeopathic medicines and in vitro studies with isolated cell systems to assess changes in the mechanisms of cell adaptation and intracellular signaling facing variable homeopathic treatments. The amount of articles published over time enabled several systematic reviews. Recently, demonstration that homeopathic medicines might modify cell functions through epigenetic mechanisms (DNA methylation and demethylation) paved the road for a fully new field of research. In parallel, the discovery of nanoparticles and specific physical properties of homeopathic dilutions brought light to a previously poorly known field, as it was believed that homeopathic dilutions consist in nothing but water. Thus being, challenges for the future concern the demonstration, or not, of the interrelationship between both phenomena.

Results there was no statistical difference between the types of intervention considering the average of correct answers of the productions and the number of sessions. There was a significant effect for pre- and post-therapy conditions in the comparison PCC-R values ​​for both models. The individuals in the GC had the PCC-R values higher than those of GG. Conclusion both models of intervention present similar results, providing an improvement in the individuals phonological performance from the first session.

The role of proteasome in muscle wasting of experimental arthritis

Abstract Background Rheumatoid arthritis is an autoimmune inflammatory disease that often leads patients to muscle impairment and physical disability. This study aimed to evaluate changes in the activity of proteasome system in skeletal muscles of mice with collagen-induced arthritis (CIA) and treated with etanercept or methotrexate. Methods Male DBA1/J mice were divided into four groups (n = 8 each): CIA-Vehicle (treated with saline), CIA-ETN (treated with etanercept, 5.5 mg/kg), CIA-MTX (treated with methotrexate, 35 mg/kg) and CO (healthy control group). Mice were treated two times a week for 6 weeks. Clinical score and hind paw edema were measured. Muscles were weighted after euthanasia and used to quantify proteasome activity, gene (MuRF-1, PMSα4, PSMβ5, PMSβ6, PSMβ7, PSMβ8, PSMβ9, and PSMβ10), and protein (PSMβ1, PSMβ5, PSMβ1i, PSMβ5i) expression of proteasome subunits. Results Both treatments slowed disease development, but only CIA-ETN maintained muscle weight compared to CIA-MTX and CIA-Vehicle groups. Etanercept treatment showed caspase-like activity of 26S proteasome similar to CO group, while CIA-Vehicle and CIA-MTX had higher activity compared to CO group (p: 0.0057). MuRF-1 mRNA expression was decreased after etanercept administration compared to CIA-Vehicle and CO groups (p: 0.002, p: 0.007, respectively). PSMβ8 and PSMβ9 mRNA levels were increased in CIA-Vehicle and CIA-MTX compared to CO group, while CIA-ETN presented no difference from CO. PMSβ6 mRNA expression was higher in CIA-Vehicle and CIA-MTX groups than in CO group. Protein levels of the PSMβ5 subunit were increased in CO group compared to CIA-Vehicle; after both etanercept and methotrexate treatments, PSMβ5 expression was higher than in CIA-Vehicle group and did not differ from CO group expression (p: 0.0025, p: 0.001, respectively). The inflammation-induced subunit β1 (LMP2) was enhanced after methotrexate treatment compared to CO group (p: 0.043). Conclusions The results of CIA-Vehicle show that arthritis increases muscle proteasome activation by enhanced caspase-like activity of 26S proteasome and increased PSMβ8 and PSMβ9 mRNA levels. Etanercept treatment was able to maintain the muscle weight and to modulate proteasome so that its activity and gene expression were compared to CO after TNF inhibition. The protein expression of inflammation-induced proteasome subunit was increased in muscle of CIA-MTX group but not following etanercept treatment. Thus, anti-TNF treatment may be an interesting approach to attenuate the arthritis-related muscle wasting.

ABSTRACT Objective: to develop and analyze content and face validity evidence of a board game to promote healthy lifestyle habits for patients with coronary artery disease. Method: this is a psychometric study of development and validity of a board game for health education. Data collection was carried out between October 2021 and January 2022. Initially, the game rules were described and, sequentially, themes related to cardiovascular prevention were identified, used as a basis for card development. The game was submitted to assessment by 14 experts in terms of clarity, theoretical relevance, practical relevance, image visibility and relationship between image and text, through a Likert scale score. The content validity coefficient was calculated for each round, with a coefficient greater than 0.57 being considered valid. New assessment rounds were performed until the appropriate coefficient was reached. Results: the board game was built containing images of anthropomorphized hearts alluding to healthy lifestyle habits and 45 spaces. A total of 69 cards were developed containing the themes of healthy eating, physical activity and the importance of smoking and alcohol cessation. In the first round of assessment, three cards did not reach the minimum content validity coefficient. They were reformulated and sent to a second round of assessment, and was considered validated in this new round. Conclusion: the game, its rules and its content showed adequate content validity evidence after the second round. Further studies to analyze its effect on lifestyle modification should be carried out.

Sildenafil in endotoxin-induced pulmonary hypertension: an experimental study

Abstract Background Sepsis and septic shock still represent great challenges in critical care medicine. Sildenafil has been largely used in the treatment of pulmonary arterial hypertension, but its effects in sepsis are unknown. The aim of this study was to investigate the hypothesis that sildenafil can attenuate endotoxin-induced pulmonary hypertension in a porcine model of endotoxemia. Methods Twenty pigs were randomly assigned to Control group (n = 10), which received saline solution; or to Sildenafil group (n = 10), which received sildenafil orally (100 mg). After 30 minutes, both groups were submitted to endotoxemia with intravenous bacterial lipopolysaccharide endotoxin (LPS) infusion (4 µg.kg-1.h-1) for 180 minutes. We evaluated hemodynamic and oxygenation functions, and also lung histology and plasma cytokine (TNFα, IL-1β, IL6, and IL10) and troponin I response. Results Significant hemodynamic alterations were observed after 30 minutes of LPS continuous infusion, mainly in pulmonary arterial pressure (from Baseline 19 ± 2 mmHg to LPS30 52 ± 4 mmHg, p< 0.05). There was also a significant decrease in PaO2/FiO2 (from Baseline 411 ± 29 to LPS180 334 ± 49, p< 0.05). Pulmonary arterial pressure was significantly lower in the Sildenafil group (35 ± 4 mmHg at LPS30, p< 0.05). The Sildenafil group also presented lower values of systemic arterial pressure. Sildenafil maintained oxygenation with higher PaO2/FiO2 and lower oxygen extraction rate than Control group but had no effect on intrapulmonary shunt. All cytokines and troponin increased after LPS infusion in both groups similarly. Conclusion Sildenafil attenuated endotoxin-induced pulmonary hypertension preserving the correct heart function without improving lung lesions or inflammation.

Evaluation of oxidative stress in an experimental model of Crohn's disease treated with hyperbaric oxygen therapy

Abstract Introduction: Treatments of Inflammatory Bowel Disease (IBD) are able to control symptoms in most cases, however, a fraction of patients do not improve or have a loss of response to treatments, making it important to explore new therapeutic strategies. Hyperbaric oxygen therapy (HBO) may represent one of them. The aim of this study was to evaluate the effects of HBO therapy in an experimental model of IBD. Methods: Sixty male BALBc mice were divided into six groups. Group 1 was colitis-induced with trinitrobenzene sulfonic acid (TNBS) + ethanol, group 2 received TNBS + ethanol plus HBO, group 3 received only ethanol, group 4 received ethanol plus HBO, group 5 received saline solution, and group 6 received saline solution plus HBO. HBO was performed for four days, subsequently, the mice were evaluated daily. At the end of the study, samples from the intestine were collected for histological analysis as well as for measurement of antioxidant enzymes and cytokine levels. Results: HBO significantly improved the clinical and histological status of the animals. Treatment with HBO increased the activity of the antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx) in all of the groups; moreover, the difference was only significant between the TNBS and TNBS + HBO groups and treatments promoted a reduction in the proinflammatory cytokines IFN-γ, IL-12, IL-17 and TNF-α and increased the anti-inflammatory cytokines IL-4 and IL-10, with no changes in IL-13. Conclusion: HBO effectively treats TNBS-induced colitis by increasing the activity of antioxidant enzymes and modulating cytokine profiles.

RESUMO A capacidade tática nos jogos esportivos coletivos se baseia na relação com os conhecimentos que o praticante possui por meio de suas experiências anteriores, e a escola deve oportunizá-las, a fim de promover a formação geral dos alunos. O objetivo do estudo foi avaliar os impactos no conhecimento tático processual (CTP) de escolares em formação esportiva geral após um programa híbrido de ensino. Participaram 40 escolares (20 no grupo experimental-GE e 20 no grupo controle-GC) com idades entre 8 e 10 anos (7,85 ± 0,48), de ambos os sexos. Aplicou-se o Teste de Conhecimento Tático Processual: Orientação Esportiva para avaliação do CTP antes e após 17 sessões de aulas com um programa híbrido de ensino que utilizou conteúdos das propostas metodológicas da Iniciação Esportiva Universal (IEU) e da Escola da Bola (EB). A intervenção no GE provocou melhora significativa no CTP dos escolares para as ações em ataque e defesa com mãos e pés quando comparado ao CG com tamanho de efeito grande. Conclui-se que a utilização desse programa híbrido de ensino (IEU + EB) aplicado nas aulas de educação física (EF) foi capaz de melhorar o CTP de escolares.

ABSTRACT The tactical capacity in team sports is based on the relationship with the knowledge that the practitioner has through his previous experiences, and the school must provide them in order to promote the general formation of the students. The aim of this study was to evaluate the impacts on the procedural tactical knowledge (PTK) of students in general sports formation after a hybrid teaching program. Participants were 40 students (20 in the experimental group-EG and 20 in the control group-CG) aged between 8 and 10 years old (7.85 ± 0.48), of both sexes. The PTK test: Sports Orientation was applied to evaluate the PTK before and after 17 sessions of school classes with a hybrid teaching program that used contents of the methodological proposals of the Universal Sports Initiation (USI) and the Ball School (BS). The intervention in the EG caused a significant improvement in the PTK of the students for the actions in attack and defense with hands and feet when compared to the GC with large effect size. It is concluded that the use of this hybrid teaching program (USI + BS) applied in physical education classes was able to improve the PTK of students.
