Under the backdrop of the "Healthy China 2030" strategy, running has become the most common form of exercise. Fitness running is a kind of endurance aerobic exercise. Compared with swimming, aerobics, and other sports with high activity and intensity, the risk of lower limb fatigue injury during fitness running is higher. In this review paper, the risk factors for running-related injuries were summarized by consulting and analyzing the database and focuses on discussing and analyzing the impact of running on joints. The results showed that hip adduction, knee bending, and ankle joint abnormalities are the three joint-related factors that cause the main injuries during running. Four rehabilitation intervention methods for running-related injuries were proposed, that can guide patients to generate personalized rehabilitation treatment plans through training.

BACKGROUND:Ligaments are an important structure for stabilizing the lumbar spine,and they are prone to degenerative changes with age.Currently,there is limited research on lumbar ligaments. OBJECTIVE:To investigate the effect of different combinations of ligament injuries on biomechanical characteristics of lumbar spine under four motion states of forward bending,backward extension,lateral bending,and torsion under a certain sequence of ligament injuries. METHODS:A finite element model of the L4-L5 segment of the lumbar spine was established,and corresponding moments were applied to simulate four motion states of forward bending,backward extension,lateral bending,and torsion.The combined injuries of the ligaments were performed in order to obtain the motion range of each vertebra and the stress of each ligament. RESULTS AND CONCLUSION:(1)Every time a ligament was removed,the remaining ligament stress would increase.Under all four working conditions,capsular ligament would experience the highest stress,especially during forward bending.With the removal of ligaments,the range of motion of the vertebrae was also continuously increasing.(2)When flexing forward,after removing the first ligament capsular ligament,the average stress change in the remaining ligament was the highest,followed by the removal of supraspinous ligament.After removing capsular ligament,the change rate of range of motion was the highest,while after removing posterior longitudinal ligament,the change rate of range of motion was the lowest.(3)When extending backward,all ligaments had the highest rate of stress change after removing capsular ligament,the highest rate of range of motion change after removing capsular ligament,and the lowest rate of range of motion change after removing posterior longitudinal ligament.(4)When bending,the stress change rate of interspinous ligament decreased after removing intertransverse ligament,while supraspinous ligament increased more.After removing capsular ligament and interspinous ligament,the range of motion change rate increased significantly.(5)During lateral bending,after removing capsular ligament,the stress change rate of the remaining ligament was much higher than that of other ligament damage combinations,and the range of motion change rate was the highest after removing capsular ligament.In other cases,the range of motion change rate did not exceed 8%.(6)If the root ligament is damaged,the remaining ligaments will undergo stress compensation.Ligament damage will affect the stability of the lumbar spine,with minimal impact in cases of lateral curvature.Patients with lumbar instability should avoid forward flexion and backward extension movements,which can make it easier to detect the pathological condition of the ligaments.(7)Capsular ligament is an important structure for maintaining lumbar stability,and supraspinous ligament plays a significant role in anterior flexion,maintaining the integrity of the entire lumbar ligament.

BACKGROUND:Ligaments are important structures in maintaining the stability of the lumbar spine,and these structures are prone to degradation due to the generated mechanical stress.However,there are few studies on ligament injuries. OBJECTIVE:To determine the range of motion and stress of each ligament in the state of motion based on a three-dimensional finite element model,and to systematically explore the influence of ligament injury on the stability of the lumbar spine and its biomechanical significance. METHODS:The L4-L5 lumbar finite element model was established.All free forces on the lower surface of L5 were constrained,and a torque of 5 N·m was applied to simulate the motion states of the lumbar spine.Progressive ligament damage was simulated by changing Young's modulus of the ligament. RESULTS AND CONCLUSION:(1)The extension range of motion of most ligament injuries increased significantly.In contrast,there was no significant change in the lateral bending range of motion.(2)The range of motion of capsular ligament injury increased significantly in flexion,extension and lateral bending.The extension range of motion increased significantly after the anterior longitudinal ligament injury.Intertransverse ligament injury resulted in a significant increase in the lateral bending range of motion.(3)After a single ligament injury,the most significant change in range of motion was observed during extension.After a single ligament injury,the stress of the remaining ligaments increased,especially the capsular ligament.The stress changes of the interspinous ligament and ligamentum flavum were the least obvious.Ligament stress changes least in lateral bending and most in torsion.(4)Ligament damage did not result in major changes in disc pressure,indicating that ligament injury leads to an increased range of motion of the lumbar spine and affects the stability of the lumbar spine.(5)Capsular ligament was stable in flexion,extension and lateral bending.The anterior longitudinal ligament showed a stable extension;the intertransverse ligament stabilizes the lateral curve.(6)Extension exercise is sensitive to a ligament injury,and the pathological changes of the ligament can be examined by extension exercise.(7)Stress compensation was given to the remaining ligaments to maintain the stability of the lumbar spine after a single ligament injury.(8)Interspinous ligament and ligamentum flavum injuries have the least impact on the peripheral ligaments,while capsular ligament injuries have the greatest impact on the peripheral ligaments.(9)The ligament injury has the least effect on the residual ligament stress during lateral bending exercise,while it has the greatest effect on the ligament stress during the twisting exercise.Patients with ligament injury should avoid twisting exercises.Ligament injuries do not affect disc pressure.

To develop a framework for clinical teaching management (CTM) position competencies, and to initiate the preliminary application of this framework.

The theory of “diagnosing diseases with sinews” means that through the diagnosis and examination of the channel sinews at the site of the lesion， the surplus and deficit state of qi and blood in the channel sinews， vessles and channels， and the degree of damage to the organism caused by the disease and evils， can be determined， forming the three elements （the nature of the disease， the location of the disease， and the disease tendency） of the disease diagnosis can be closely integrated to form the trinity of diagnostic modes， which is “examining the disease nature by sinews， identifying the pattern by sinews， and determining the tendency by sinews”. For intractable facial paralysis， the method of “diagnosing diseases with sinews” can be adopted， in which the morphological changes of the channel sinews are judged through diagnosis by observation， the traditional Chinese patterns are identified through diagnosis by palpation， and the points of meridian tendons and the circulation of tendon and treatment lines are determined through diagnosis by circulation. The “diagnosing diseases with sinews” not only helps to accurately determine the disease condition， patterns and development trend， but also helps to adopt targeted treatment for the disease and prevent the disease from spreading， and providing ideas and methods for the clinical diagnosis and treatment of intractable facial paralysis.

The correspondence between prescription and syndrome is the advantage and characteristic of traditional Chinese medicine(TCM)treatment.However,the pathogenesis of clinical diseases is complex and the condition is changeable,and the clinical application is difficult to achieve the maximum effect under the existing cognition of the correspondence between prescription and syndrome.In this paper,the five categories of physiological characteristics,pathological characteristics,constitution,syndrome,and disease of the longitudinal classification of"TCM state"are introduced into the correspondence of prescription and syndrome.Under the vertical perspective of"TCM state",the theoretical connotation of the correspondence between prescription and syndrome is interpreted as"correspondence between prescription and state",namely correspondence of"prescription-physiological characteristics",correspondence of"prescription-pathological characteristics",correspondence of"prescription-constitution",correspondence of"prescription-syndrome",and correspondence of"prescription-disease".It is hoped to accurately grasp the corresponding connotation of the correspondence between prescription and syndrome,in order to deepen the clinical thinking mode of TCM.

Cancer stem cells(CSCs)are a small group of cells found in tumors that have same self-renewing properties as nor-mal stem cells.In recent years,with continuous development of science and technology in various aspects,people's research on tumor diseases has been deepened.CSCs has been defined as a key factor in promoting tumor development,especially participating in pro-moting tumor recurrence,metastasis,chemotherapy resistance,etc.Currently,CD133 has become one of popular CSCs markers,and can be highly expressed in a variety of CSCs.CD133 is closely related to diagnosis of cancer diseases,and plays an important role in dignosis and drug targeting for gastric cancer,lung cancer,brain tumor,liver cancer,ovarian cancer and colorectal cancer.This article reviews structure,function,immune mechanism escape of CD133,signal pathway of CD133 in tumorigenesis,and correlation of CD133 with various tumors as well.

In order to meet the needs of the comprehensive development of life sciences and medicine,and fulfill the coher-ence and intersectionality of undergraduate experimental courses,it is necessary to break the teaching contents of conventional single experiment courses,and carry out the teaching reform of tumor comprehensive experimental course.Molecular biology and immuno-logy are two basic subjects which are closely related to the scientific research of life science,basic medicine and clinical medicine.Meantime,they are important sources for students to acquire skill training and scientific thinking as well.In this study,we try to inte-grate the experimental courses about the analysis and intervention of tumor-related genes based on the molecular biology and immunology technologies,facilitating to establish a new tumor comprehensive experimental course system.The course focuses on the development of students'logical thinking,and simulates the scientific research process through database screening,experimental operation,experi-mental report and paper writing,so as to significantly improve undergraduates'interest in scientific research and their ability to com-bine theory with practice,and cultivate students'rigorous scientific and innovative thinking ability as well as their ability to compre-hensively analyze and solve problems.It lays a solid foundation for future postgraduate related scientific research.At the same time,it is helpful to train teachers with multi-disciplinary knowledge reserves,and promote the coordinated development of scientific research through teaching.

Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.

A case of giant liquid tophus in both lower legs was reported. The patient was a 41-year-old man with a history of gout for more than 10 years. The patient had hyperlipidemia and prediabetes, and the long-term use of hormone cortisol drugs was suspected. After standardized treatment for lowering uric acid, reducing blood lipids, and correcting glucose intolerance, the patient lost 12 kg over six months. The patient was admitted to the hospital upon discovering symmetrical enlargement of both calves. Ultrasound showed subcutaneous masses with clear boundaries behind the gastrocnemius muscle, approximately 14.9 cm×6.7 cm on the left and 13.6 cm×4.6 cm on the right. Based on the clinical information and morphological features, a diagnosis of gouty tophus was made. Following ultrasound-guided puncture drainage, aspirate about 200 mL fluid from the subcutaneous masses of each lower legs. The patient continued to receive standardized uric acid-lowering treatment and the patient′s condition improved. For such atypical giant liquid tophus, clinical practitioners should remain vigilant, differentiating them from tumors, infections, autoimmune diseases, and promptly perform pathological examinations through puncture to be diagnosed. After a definitive diagnosis, surgical excision can be performed concurrently with standardized uric acid-lowering treatment to achieve a favorable prognosis.
