ABSTRACT
La preparación física, como parte del entrenamiento de los cadetes, busca poner en óptimo estado al practicante, perfecciona sus aptitudes naturales y desarrolla al máximo sus capacidades físicas por medio de ejercicios sistemáticos. En ese sentido, la velocidad de reacción durante la defensa personal constituye un importante aspecto a tratar; sin embargo, la observación y análisis de la realidad educativa en el Instituto de Enseñanza Superior del Ministerio del Interior, en Santiago de Cuba, reveló insuficiencias que limitan el logro de altos niveles en la velocidad de reacción. El objetivo del estudio consistió en elaborar una metodología para el desarrollo de la velocidad de reacción durante la defensa personal, en los cadetes de la carrera Ciencias de la Seguridad del Estado del Ministerio del Interior. En esa línea de pensamiento, se realizó una investigación con enfoque mixto y diseño cuasi experimental que empleó como métodos empíricos la revisión documental, la observación científica y la entrevista no estructurada; se utilizó la estadística inferencial por medio de la prueba de rangos de Wilcoxon para muestras relacionadas, lo que permitió conocer la eficiencia de los ejercicios especiales que se aplicaron. La calidad de la metodología quedó corroborada por los resultados obtenidos en la aplicación del criterio de expertos en la variante "Delphi" y del prexperimento, confirmados por diferentes técnicas estadísticas que resaltan la funcionalidad, sostenibilidad, pertinencia y factibilidad de la propuesta.
A preparação física, como parte do treinamento dos cadetes, busca colocar o praticante em ótimas condições, aperfeiçoar suas aptidões naturais e desenvolver ao máximo suas capacidades físicas por meio de exercícios sistemáticos. Nesse sentido, a velocidade de reação durante a defesa pessoal é um aspecto importante a ser abordado; no entanto, a observação e a análise da realidade educacional no Instituto de Ensino Superior do Ministério do Interior, em Santiago de Cuba, revelaram insuficiências que limitam a obtenção de altos níveis de velocidade de reação. O objetivo do estudo foi elaborar uma metodologia para o desenvolvimento da velocidade de reação durante a autodefesa, em cadetes do curso de Ciências de Segurança do Estado do Ministério do Interior. Nessa linha de pensamento, foi realizada uma pesquisa com abordagem mista e desenho quase experimental, utilizando como métodos empíricos a revisão documental, a observação científica e a entrevista não estruturada; foi utilizada a estatística inferencial por meio do teste de postos de Wilcoxon para amostras relacionadas, o que permitiu conhecer a eficiência dos exercícios especiais aplicados. A qualidade da metodologia foi corroborada pelos resultados obtidos na aplicação de critérios de especialistas na variante "Delphi" e no pré-experimento, confirmados por diferentes técnicas estatísticas que destacam a funcionalidade, a sustentabilidade, a relevância e a viabilidade da proposta.
Physical preparation, as part of training of the cadets, seeks to put the practitioner in optimal condition, perfects their natural aptitudes and develops their physical capabilities to the maximum through systematic exercises. In this sense, the speed of reaction during self-defense is an important aspect to address; however, the observation and analysis of the educational reality at the Institute of Higher Education of the Ministry of the Interior, in Santiago de Cuba, revealed insufficiencies that limit the achievement of high levels in reaction speed. The objective of the study was to develop a methodology for the development of reaction speed during self-defense, in the cadets of the State Security Sciences career of the Ministry of the Interior. In this line of thought, research was carried out with a mixed approach and quasi-experimental design that used documentary review, scientific observation and unstructured interviews as empirical methods; inferential statistics was used through the Wilcoxon rank test for related samples, which made it possible to know the efficiency of the special exercises that were applied. The quality of the methodology was corroborated by the results obtained in the application of expert criteria in the "Delphi" variant and of the pre-experiment, confirmed by different statistical techniques that highlight the functionality, sustainability, relevance and feasibility of the proposal.
ABSTRACT
By analysing the similarity between defense qi and leukocytes in terms of function， site of action， and circadian rhythm， it is proposed that in traditional Chinese medicine （TCM）， the pathogenesis of leukopenia is defense qi deficiency. By analyzing the relevant discussions on the generation and transmission of defense qi in TCM classics， it is believed that the original qi in lower jiao （焦） is the source of defense qi， while the water and grain qi in middle jiao enriches defense qi， and the upper jiao transmits and distributes defense qi to the whole body. Therefore， when treating leukopenia after chemotherapy with TCM， Guilu Erxian Gelatin （龟鹿二仙胶） and Yougui Pill （右归丸） are often used to tonify the kidney and supplement essence， and moxibustion at Guanyuan （CV 4） and Qihai （CV 6） is usually accompanied to replenish the original qi in lower jiao and enrich the source of defense qi. Guipi Decoction （归脾汤）， Buzhong Yiqi Decoction （补中益气汤）， Shenling Baizhu Powder （参苓白术散）， and Sijunzi Decoction （四君子汤） are often suggested to strengthen spleen and replenish qi， in combination with moxibustion at Zhongwan （CV 12） and Zusanli （ST 36） to transport the spleen and stomach in the middle jiao to enrich the defense qi. Modified Guizhi Decoction （桂枝汤） to harmonize nutrient and defensive aspects is often used， and moxibustion at Dazhui （GV 14） and Feishu （BL 13） or scraping is added to dredge the striae and interstice in the upper jiao and promote transmission and dissemination of the defense qi. Considering the whole process of generation and distribution of defense qi， it is suggested to choose the most appropriate treatment modality flexibly， and combine internal treatment with external treatment， in order to provide ideas for the treatment of leukopenia in tumour patients.
ABSTRACT
Este artículo analiza la producción académica relacionada con la acción colectiva, movilización social y defensa territorial en Colombia durante las últimas dos décadas (2000-2020). Para esto, se parte de un contexto de conflicto social, político y económico, comenzando con la Política de Defensa y Seguridad Democrática y finalizado con la implementación de los acuerdos de paz con las Fuerzas Armadas Revolucionarias de Colombia (FARC). Se soporta en referentes teóricos propios del estudio de la acción colectiva, los movimientos sociales y la defensa territorial tanto de la escuela anglosajona clásica como en la escuela latinoamericana contemporánea. La metodología implementada es documental, relacional y espacial, incluso trabajos doctorales hechos en Colombia y artículos en revistas académicas a escala global. Lo anterior evidencia el crecimiento en la cantidad de este tipo de trabajos, sus principales temas y vacíos, así como la distribución espacial de los casos de estudio abordados.
This article analyzes the academic production related to the processes of collective action, social mobilization and territorial defense in Colombia during the last two decades (2000-2020). A context of social, political, and economic conflict is taken as a starting point. Beginning with the Democratic Security policy and ending with the implementation of the peace agreements with the FARC. This work is supported by theoretical references typical of the study of collective action, social movements, and territorial defense, both from the classical Anglo-Saxon tradition, as well as the contemporary Latin American one. The analysis is based on a documentary, relational and spatial methodology, which includes the review of doctoral works done in Colombia, and articles in academic journals on a global scale. The above evidences the growth in the amount of this type of work, its main themes as well as its gray areas, also the spatial distribution of the case studies addressed.
ABSTRACT
Pendrin is an electroneutral anion exchanger transporter, residing in the apical region of airway epithelium cells.It is responsible for the reabsorption of chloride(Cl -) and the exchange of bicarbonate(HCO 3－)or thiocyanate(SCN -) to the lumen.It is mainly involved in regulating the pH and thickness of airway surface liquid(ASL), mucin secretion, and airway defense, which is of great significance for maintaining the stability of the airway surface microenvironment.The expression of pendrin is significantly up-regulated in bronchial asthma, which is closely related to the pathological processes of the lung in bronchial asthma, such as airway hyperresponsiveness, neutrophil infiltration, and increased mucin secretion.Inhibiting the function of pendrin may be a new target for the treatment of bronchial asthma.
ABSTRACT
Human RNase A (human RNase A) superfamily contains 13 members (RNase 1~RNase 13) with different biological activities. In addition to the conserved catalytic sequence, its protein structure also has a significant diversity of sequences, which determines that human ribonuclease A can exert biological functions other than ribonuclease activity. Human RNase A superfamily members are expressed in various immune cells such as eosinophils, neutrophils, monocytes, and macrophages and can be secreted to exert various biological functions, including anti-microbial activity, promote host defense, participate in angiogenesis and sperm maturation, etc. Some members of the human ribonuclease A superfamily can exert antimicrobial and antiparasitic activities through direct actions such as hydrolysis of viral RNA, inhibition of viral replication, destruction of bacterial cell walls, promotion of microbial aggregation, damage to parasitic cell membranes and mitochondrial membranes, and indirect actions mediated by host innate immune cells, thereby participating in host defense. This article reviews the antimicrobial (including viruses, bacteria, and fungi) and antiparasitic activities of human ribonuclease A and their mechanisms of action. It also prospects the prospects of human ribonuclease A as an active antimicrobial substance and innate immune molecule for the treatment of severe and drug-resistant microbial infections.
ABSTRACT
Fear, a negative emotion triggered by dangerous stimuli, can lead to psychiatric disorders such as phobias, anxiety disorders, and depression. Investigating the neural circuitry underlying congenital fear can offer insights into the pathophysiological mechanisms of related psychiatric conditions. Research on innate fear primarily centers on the response mechanisms to various sensory signals, including olfactory, visual and auditory stimuli. Different types of fear signal inputs are regulated by distinct neural circuits. The neural circuits of the main and accessory olfactory systems receive and process olfactory stimuli, mediating defensive responses like freezing. Escape behaviors elicited by visual stimuli are primarily regulated through the superior colliculus and hypothalamic projection circuits. Auditory stimuli-induced responses, including escape, are mainly mediated through auditory cortex projection circuits. In this article, we review the research progress on neural circuits of innate fear defensive behaviors in animals. We further discuss the different sensory systems, especially the projection circuits of olfactory, visual and auditory systems, to provide references for the mechanistic study of related mental disorders.

Objective@#To investigate the prevalence of depression and anxiety among transgender populations and the correlation with defense mechanism, so as to provide the evidence for improving mental health among transgender populations. @*Methods@#Transgender populations that visited Psychosexual Outpatient Department of Beijing Huilongguan Hospital for the first time from December 2020 to December 2021 were enrolled. Participants' demographics, depression, anxiety and type of defense mechanisms were collected using self-designed questionnaires, Self-rating Depression Scale, Self-rating Anxiety Scale and Defense Style Questionnaire (DSQ). Factors affecting depression and anxiety were identified using a multivariable logistic regression model. @*Results@#Totally 126 transgender individuals were enrolled, including 95 men (75.40%) with a mean age of (21.53±4.55) years and 31 women (24.60%) with a mean age of (23.58±5.55) years. The prevalence of depression was 46.83% among participants, including 44.07% of participants with mild depression, 30.51% with moderate depression and 25.42% with severe depression, and the prevalence of anxiety was 26.19% among participants, including 60.61% of participants with mild anxiety, 21.21% with moderate anxiety and 18.18% with severe anxiety. The detection of depression was 54.74% among men and 22.58% among women (P<0.05), and the detection of both depression (62.79% vs. 38.55%, P<0.05) and anxiety (41.86% vs. 18.07%, P<0.05) was significantly higher among transgender populations with self-injury or suicide behaviors than among those without. Multivariable logistic regression analysis showed that immature defense mechanisms increased the risk of depression (OR=1.034, 95%CI: 1.018-1.051) and anxiety (OR=1.031, 95%CI: 1.014-1.049) among transgender populations, while mature defense mechanisms reduced the risk of depression (OR=0.887, 95%CI: 0.832-0.946) and anxiety (OR=0.878, 95%CI: 0.821-0.938) among transgender populations.@*Conclusions@#The prevalence of depression and anxiety was 46.83% and 26.19% among transgender populations included in this study. Mature defense mechanisms are beneficial to reduce the risk of depression and anxiety among transgender populations. Key words： transgender population depression anxiety defense mechanism
ABSTRACT
El sistema respiratorio cumple múltiples funciones no respiratorias, entre ellas es fundamental su rol en la defensa del organismo frente a una gran variedad de agentes externos potencialmente nocivos. Para ello, cuenta con mecanismos de protección de la vía aérea, dado por sus estructuras anatómicas, reflejos y el transporte mucociliar, además de un complejo y amplio desarrollo del sistema inmune pulmonar. El objetivo de este articulo es revisar los conceptos y componentes más importantes de función defensiva del sistema respiratorio.
The respiratory system fulfills multiple non-respiratory functions, including its role in defending the body against a wide variety of potentially harmful external agents. For this, it has airway protection mechanisms, given by its anatomical structures, reflexes and mucociliary transport, as well as a complex and extensive development of the pulmonary immune system. The objective of this article is to review the most important concepts and components of the defensive function of the respiratory system.

El artículo aborda un tema particularmente sensible para la investigación científica como lo son los estudios que involucran directamente a niños y niñas. El valor social y la relevancia científica de la investigación en este campo es indudable, sin embargo, su justificación requiere especial detenimiento en las condiciones para el ejercicio de sus derechos antes, durante y después del proceso de investigación. La naturalización de su denominación como "población vulnerable" y el ejercicio de su autonomía relativa, son dos dimensiones principales aquí. El artículo navega por preguntas que no se resuelven aquí precisamente, ¿qué garantías para el proceso efectivo de asentimiento informado?, ¿cómo acompañar en la toma de decisiones sin sustituir al niño y la niña? Sin embargo, sí avanza en la instalación de dilemas y aspectos conceptuales y reflexivos sustantivos en la práctica científica.
The article deals with a particularly sensitive topic for scientific research, such as research studies that directly involve boys and girls. The social value and scientific relevance of research in this field is unquestionable; however, its justification requires special care regarding the conditions of children's rights before, during and after the research process. The naturalization of their denomination as a "vulnerable population" and the exercise of their relative autonomy are the two main dimensions of this study. This paper explores questions that are not answered in it precisely: what guarantees informed consent during the effective process? How to accompany the decision making process without replacing the boy and the girl? However, the study makes progress regarding the setting of substantive conceptual and reflective dilemmas and aspects in scientific practice.

Abstract Introduction: The study of herbivory is fundamental in ecology and includes how plants invest in strategies and mechanisms to reduce herbivore damage. However, there is still a lack of information about how the environment, plant density, and functional traits influence herbivory in aquatic ecosystems. Objective: To assess if there is a relationship between herbivory, environmental variables, and plant traits two species of Montrichardia, a neotropical aquatic plant. Methods: In September 2018, we studied 78 specimens of Montrichardia arborescens and 18 of Montrichardia linifera, in 18 sites in Melgaço, Pará, Brazil. On each site, we measured water depth, distance to the margin, and plant density. From plants, we measured plant height and leaf thickness, and photographed the leaves to calculate the specific leaf area and percentage herbivory. To identify anatomical structures, we collected fully expanded leaves from three individuals per quadrat. Results: For M. arborescens, plants with thicker leaves and higher specific leaf area have less herbivore damage. For M. linifera, plants from deeper sites and with thicker leaves had more herbivore damage, while plants that grew farther from the margin had less damage. We found anatomical structures related to defense, such as idioblast cells with phenolic compounds, and cells with solid inclusions that can contribute to avoiding severe damage. Conclusions: Herbivory in these Montrichardia species can be explained by a combination of plant and environmental traits (patch isolation and water depth). The main plant traits are leaf thickness and area, but chemical compounds and solid inclusions also help Montrichardia to sustain less damage than other macrophytes.
Resumen Introducción: La herbivoría es fundamental para comprender cómo las plantas invierten en diferentes estrategias para evitar la depredación, lo que implica diferentes mecanismos de defensa. Factores relacionados con el medio ambiente, la densidad de plantas y/o los rasgos funcionales de las plantas pueden influir en la herbivoría en los ecosistemas acuáticos. Sin embargo, todavía falta información sobre cómo esos factores influyen en la herbivoría en los ecosistemas acuáticos y pueden contribuir a la carga de herbivoría. Objetivo: Evaluar si existe una relación entre la herbivoría y las variables ambientales (p. ej., profundidad del agua y distancia al margen), los factores ecológicos (densidad de plantas) y los rasgos estructurales de las plantas (altura, grosor de la hoja y área foliar) e indicar estructuras anatómicas que actúen junto con los rasgos estructurales en el sistema de defensa de especies de Montrichardia. Métodos: Se evaluaron 96 individuos de Montrichardia spp. (78 de M. arborescens y 18 de M. linifera, en 18 sitios) recolectados en septiembre de 2018. En cada sitio, se midió la profundidad del agua, la distancia al margen y la densidad de plantas. De los individuos, medimos la altura de la planta, el grosor de la hoja y fotografiamos las hojas para calcular el área foliar específica y la cantidad de herbivoría (en porcentaje). Para identificar las estructuras anatómicas relacionadas con la defensa de las plantas, se recogió hojas completamente expandidas de tres individuos por cuadrante. Resultados: Para M. arborescens, las plantas con hojas más gruesas y mayor área foliar específica tienen menos daño por herbivoría. Para M. linifera, las plantas con hojas más gruesas y que habitan en sitios más profundos tienen más daño por herbívoros, mientras que las plantas más alejadas del margen tienen menos daño por herbívoros. Se encontró estructuras anatómicas relacionadas con la defensa, como células idioblásticas con compuestos fenólicos y células con inclusiones sólidas que pueden contribuir a evitar daños severos en las características de las hojas. Conclusiones: Nuestros resultados indican que la herbivoría en las especies de Montrichardia podría explicarse por una combinación de características ambientales (aislamiento del parche y profundidad del agua) y de la planta. Descubrimos que los rasgos de las hojas eran factores importantes que impulsaban los cambios en la carga de herbivoría, especialmente el grosor de las hojas y el área foliar específica. Además, las especies de Montrichardia invierten en compuestos químicos e inclusiones sólidas para evitar daños graves en las hojas y, por lo tanto, pueden sufrir menos daños que otras especies de macrófitos.

Na obra de Sigmund Freud, é possível localizarmos outra teoria da neurose que não está ancorada na existência de sintomas oriundos do processo defensivo próprio ao recalque, como pudemos verificar na constituição da neurose de caráter e das neuroses atuais. A evidência de tal problemática, presente já na elaboração teórica freudiana, nos leva à atualidade de nossa clínica. Na prática psicanalítica contemporânea, nos deparamos, cada vez mais, com fenômenos sintomáticos que não correspondem a sintomas propriamente ditos. O fenômeno da obesidade para alguns sujeitos evidencia uma forma de defesa inconsciente primária, mais arcaica, sem a produção de conflito psíquico e não sendo possível a satisfação da pulsão por meio do sintoma. A obesidade pode ser localizada como uma variante da neurose.
In Sigmund Freud's work it is possible to locate another theory of neurosis that is not anchored in the existence of symptoms arising from the defensive process at work in repression, as we could see in the constitution of the character neurosis and in the current neuroses. The evidence of such a problem, already present in the Freudian theoretical preparation, takes us to the present day of our clinic. In contemporary psychoanalytic practice, we are increasingly faced with symptomatic phenomena that do not correspond to symptoms themselves. The phenomenon of obesity for some subjects is evidence of a primary, more archaic form of unconscious defense, without the production of psychic conflict, and in which it is not possible to satisfy the drive through the symptom. Obesity can be located as a variant of neurosis.
Il est possible de localiser, dans l'Åuvre de Sigmund Freud, une autre théorie de la névrose qui n'est pas ancrée dans l'existence de symptômes issus du processus défensif propre au refoulement, comme nous avons pu vérifier dans la constitution de la névrose de caractère et des névroses actuelles. L'évidence d'une telle problématique, présente déjà dans l'élaboration théorique freudienne, nous conduit à l'actualité de notre clinique. Dans la pratique psychanalytique contemporaine, nous sommes confrontés, de plus en plus, à des phénomènes symptomatiques qui ne correspondent pas à des symptômes proprement dits. Le phénomène de l'obésité pour certains sujets met en évidence une forme de défense inconsciente primaire, plus archaïque, sans la production de conflit psychique, n'étant pas possible la satisfaction de la pulsion par le symptôme. L'obésité peut être localisée comme une variante de la névrose

Objective: To evaluate the impact of defense mechanisms at baseline on depressive symptoms after brief psychotherapies and after 6-months of follow-up among depressed patients with and without cluster B personality disorders (PDs). Methods: This quasi-experimental study nested within a randomized clinical trial included a clinical sample of adults (18-60 years) diagnosed with major depressive disorder using the Mini-International Neuropsychiatric Interview. The Millon Clinical Multiaxial Inventory-III was applied to assess PD, the Defense Style Questionnaire 40 was used to analyze defense mechanisms, and the Beck Depression Inventory was used to measure the severity of depressive symptoms. Adjusted analysis was performed by linear regression. Results: The final sample consisted of 177 patients diagnosed with major depressive disorder, of whom 39.5% had cluster B PDs. Immature defenses at baseline significantly predicted the persistence of depressive symptoms at post-intervention and at 6-months of follow-up only in patients with PDs. Conclusion: In depressed patients with cluster B PDs, immature defenses predicted a poor response to brief therapies. The assessment of immature defenses at baseline can help identify patients at greater risk of poor therapeutic results and enable more appropriate treatment choices.

Consultation with specialists shows the need to implement a systematic self-defense training process at the Naval High School. The indicators of relevance, feasibility, priority and comprehensiveness are presented as positive in the design of a prospective process to provide professional improvement to Ecuadorian naval personnel in the aspect of self-defense.
ABSTRACT
ObjectiveTo explore the psychological defense styles and family environment among male prisoners of different terms of imprisonment， and to analyse the relationship between their psychological defense styles and family environment. MethodsA total of 200 male prisoners in a prison in Guangdong were randomly selected from April to June 2015， and they were classified into less than 5 years of imprisonment group （n=108） and 5 years or more imprisonment group （n=92）. Their defense style and family environment were evaluated by Defense Style Questionnaire （DSQ） and Family Environment Scale-Chinese Version （FES-CV）. Pearson correlation analysis was used to test the correlation between each scale score. ResultsThe factor scores of immature defense mechanism and intermediate defense mechanism of DSQ in the group with less than 5 years of imprisonment were lower than those in the group with 5 years or more imprisonment， with statistically significant differences （t=4.198， 1.137， P<0.01）. The scores of FES-CV family intimacy， emotional expression and organizational factors in less than 5 years of imprisonment group were higher than those in 5 years or more imprisonment group （t=3.122， 2.993， 2.203， P<0.01）， and the scores of contradiction factors were lower than those in 5 years or more imprisonment group （t=-3.682， P<0.01）. The scores of DSQ immature， intermediate defense mechanism and concealment factor of male prisoners were negatively correlated with the scores of FES-CV family intimacy and emotional expression factor （r=-0.428~-0.172， P<0.05 or 0.01）， and the scores of 4 factors in DSQ were all positively correlated with the scores of contradiction factor in FES-CV （r=0.175~0.384， P<0.05 or 0.01）. ConclusionCompared with male prisoners with less than 5 years of imprisonment， those with 5 years or more are prone to adopt immature and intermediate defense mechanisms， and their family environments are characterized by apparent contradiction and a lack of family intimacy， emotional expression and organization. Furthermore， the defects of psychological defense mechanism of prisoners are related to their family environment.
ABSTRACT
Fluorine is a non-metallic chemical element, which often exists in the form of fluoride in nature. Long-term excessive intake of fluoride will lead to chronic fluorosis. Fluoride is mainly absorbed through the digestive tract, so the intestinal tract is more vulnerable to fluoride damage. Excessive fluoride not only destroys intestinal structure and interferes with intestinal flora and micro-environment, but also induces intestinal toxicity through oxidative stress. This article reviews the effects of fluoride on intestinal structure and defense function, aiming to provide theoretical references and new ideas for the mechanism study of fluoride-induced intestinal damage.
ABSTRACT
The application of "standardized patient" in clinical teaching of our country has the irreplaceable function, but it is still unavoidably challenged by ethics. From two aspects of medical ethics and teaching ethics, this paper puts forward the ethical basis for the justification of standardized patient application. And in order to ensure that the legitimate interests of standardized patients are not infringed, clinical teachers applying standardized patients must follow the principles of respect, protection of privacy and ethical supervision. Only in a legal and reasonable vision, can we promote the orderly development of standardized patients, and provide services for more doctors, medical students and patients.
ABSTRACT
The research on the essence of triple energizer has not reached a consensus. The correspondence between the existing understanding and the classical theory of triple energizer is still limited in terms of structure and function. According to the traditional theory， nutrient-defense takes channels as the main circulatory system， while the operation of nutrient-defense in the triple energizer remains unclear. Since little is known about the physical structure of the triple energizer， the role of triple energizer as a collection of other Zang-fu organs has been ignored in most cases. The new progress in anatomy paves the way for the research on the essence of triple energizer. The function and structure of triple energizer are similar to those of interstitium and interfacial fluid flow， which enriches our understanding of the macro and micro structures of triple energizer. The triple energizer is distributed throughout the body and composed of membrane and interstitial space. The material structure of triple energizer includes fiber scaffold， collagen fiber， mesenchymal stem cells， histiocytes， pericytes， and interstitial fluid. The functions of triple energizer include passing body fluids， operating nutrient-defense， distributing original Qi， and transmitting and changing pathogenic Qi. According to the available theories and research achievements， we put forward the concept of vertical and horizontal triple energizer， pointed out that triple energizer had independent structure and the features of Zang-fu organs， and preliminarily defined the spatial distribution of triple energizer. The relationship between channels and triple energizer is essential for discussing the operation of nutrient-defense. Telocyte （Tc） and telopod （Tp） has the characteristics of channels in function and structure. The connective tissue with the distribution of Tc and Tp belongs to the same material as the basic structure of interstitial/interfacial fluid flow system and the fibrous skeleton of interstitium. It is clear that channels and triple energizer have material commonality. From the operation paths of nutrient-defense， we proposed that channels may be soaked and attached in triple energizer and put forward the model of channels soaked and attached in triple energizer. By combining the circulation of nutrient-defense with the vertical and horizontal triple energize， we developed the theory of triple energizer-nutrient-defense loop to comprehensively describe the generation， transport， and metabolism of nutrient-defense in channels and triple energizer， aiming to provide a theoretical model for future studies of disease transmission and change from exterior to interior.
ABSTRACT
The production efficiency of microbial cell factory is determined by the growth performance, product synthetic capacity, and stress resistance of the strain. Strengthening the stress resistance is the key point to improve the production efficiency of microbial cell factory. Tolerance engineering is based on the response mechanism of microbial cell factory to resist stress. Specifically, it consolidates the cell wall-cell membrane barrier to enhance the defense against stress, accelerates the stress response to improve the damage repair, and creates tolerance evolutionary tools to screen industrial microorganisms with enhanced robustness. We summarize the regulation strategies and forecast the prospects of tolerance engineering, which plays an important role in the microbial cell factories for sustainable production of natural products and bulk chemicals.
