Exercise, as a non-pharmacological intervention, holds a pivotal role in metabolic regulation, neuroplasticity, and immune homeostasis maintenance. However, human exercise studies are constrained by ethical limitations in tissue sampling, especially for key organs such as muscles and the brain. Meanwhile, rodent models like mice exhibit physiological differences in exercise patterns and metabolic rates from human. Despite these challenges, approximately 70% of human and mouse genes are conserved, providing a molecular basis for cross-species comparisons. This paper leverages the GEPREP database, which integrates human and mouse exercise transcriptomic data from multiple platforms, to conduct a comprehensive cross-species analysis of exercise-induced gene expression patterns. We employ a stringent data standardization process, including the conversion of orthologous genes and the filtering of low-expressing genes, to ensure the accuracy and reliability of the analysis. A mixed-effects model is utilized to assess differential gene expression across multiple cohorts, identifying genes that are significantly upregulated or downregulated in response to exercise. The analysis reveals a complex pattern of gene expression, with a significant number of genes showing conserved responses between humans and mice, particularly in acute aerobic exercise, where genes such as ATF3, PPARGC1A, and ANKRD1 are commonly upregulated. These genes are implicated in muscle stress response, metabolic regulation, and muscle adaptation, highlighting the shared molecular pathways activated by exercise across species. However, the study also uncovers substantial species-specific differences in gene expression, especially in chronic aerobic exercise, where the number of divergently regulated genes increases. These differences suggest that while some fundamental biological processes are conserved, the specific regulatory mechanisms and gene expression patterns can vary significantly between humans and mice. Functional enrichment analysis further reveals that conserved genes are involved in muscle development, inflammation regulation, and energy metabolism, while species-specific genes are associated with ion transport, extracellular matrix (ECM) organization, and muscle contraction, indicating the multifaceted impact of exercise on skeletal muscle function. The findings emphasize the importance of considering species-specific differences when interpreting results from animal models and translating them to human health applications. The study highlights the need for a more nuanced understanding of the molecular underpinnings of exercise-induced adaptations and underscores the value of cross-species comparative analyses in uncovering the evolutionary and functional basis of these responses. Future research should focus on integrating multi-omics data and expanding the analysis to include other tissues to provide a more comprehensive view of the systemic effects of exercise. Additionally, the development of species-specific gene editing models and the validation of key genes in exercise physiology will further enhance our understanding of the evolutionary logic behind exercise interventions. This study not only provides valuable insights into the molecular mechanisms of exercise-induced adaptations but also underscores the necessity of validating findings from animal models in human cohorts to ensure the reliability and applicability of translational research in exercise science. By addressing these aspects, the study aims to bridge the gap between basic research and clinical applications, ultimately contributing to the development of personalized exercise prescriptions and interventions that can effectively promote health and prevent diseases.

ObjectiveTo investigate the effect of Danggui Shaoyaosan on ferroptosis in the rat model of non-alcoholic fatty liver disease （NAFLD） and explore the underlying mechanism based on the nuclear factor E₂-related factor 2 （Nrf2）/solute carrier family 7 member 11 （SLC7A11）/glutathione peroxidase 4 （GPX4） signaling pathway. MethodsThe sixty SD rats were randomly grouped as follows： control， model， Yishanfu （0.144 g·kg^-1）， and low-， medium-， and high-dose （2.44， 4.88， and 9.76 g·kg^-1， respectively） Danggui Shaoyaosan. A high-fat diet was used to establish the rat model of NAFLD. After 12 weeks of modeling， rats were treated with corresponding agents for 4 weeks. Then， the body weight and liver weight were measured， and the liver index was calculated. At the same time， serum and liver samples were collected. The levels or activities of total cholesterol （TC）， triglycerides （TG）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and Fe²⁺ in the serum and TC， TG， free fatty acids （FFA）， malondialdehyde （MDA）， superoxide dismutase （SOD）， glutathione peroxidase （GPX）， and Fe²⁺ in the liver were measured. Hematoxylin-eosin staining and oil red O staining were employed to observe the pathological changes in the liver. Immunofluorescence was used to assess the reactive oxygen species （ROS） content in the liver. Mitochondrial morphology was observed by transmission electron microscopy. The protein levels of Nrf2， SLC7A11， GPX4， transferrin receptor 1 （TFR1）， and divalent metal transporter 1 （DMT1） in the liver were determined by Western blot. ResultsCompared with the control group， the model group showed increases in the body weight， liver weight， liver index， levels or activities of TC， TG， ALT， AST， and Fe²⁺ in the serum， levels of TC， TG， FFA， MDA， Fe²⁺， and ROS in the liver， and protein levels of TFR1 and DMT1 in the liver （P<0.01）， and decreases in the activities of SOD， GPX and the protein levels of Nrf2， SLC7A11， and GPX4 in the liver （P<0.05， P<0.01）. Meanwhile， the liver tissue in the model group presented steatosis， iron deposition， mitochondrial shrinkage， and blurred or swollen mitochondrial cristae. Compared with the model group， all doses of Danggui Shaoyaosan reduced the body weight， liver weight， liver index， levels or activities of TC， TG， ALT， AST， and Fe²⁺ in the serum， levels of TC， TG， FFA， MDA， Fe²⁺， and ROS in the liver， and protein levels of TFR1 and DMT1 in the liver （P<0.01）， while increasing the activities of SOD and GPX and the protein levels of Nrf2， SLC7A11， and GPX4 in the liver （P<0.01）. Furthermore， Danggui Shaoyaosan alleviated steatosis， iron deposition， and mitochondrial damage in the liver. ConclusionDanggui Shaoyaosan may inhibit lipid peroxidation and ferroptosis by activating the Nrf2/SLC7A11/GPX4 signaling pathway to treat NAFLD.

ObjectiveTo explore the effect and mechanism of Zhishi Xiebai Guizhitang on the progression of atherosclerosis （AS） mice based on the regulation of cholesterol metabolism in foam cells by transient receptor potential channel ankyrin 1 （TRPA1）. MethodThe AS model was established on apolipoprotein E knockout （ApoE^-/-） mice with a high-fat diet. The mice were randomly divided into low-dose， middle-dose， and high-dose groups of Zhishi Xiebai Guizhitang （2.97， 5.94， 11.88 g·kg^-1） and simvastatin group （0.002 g·kg^-1）， and the drug was administered along with a high-fat diet. C57BL/6J mice were fed an ordinary diet as a normal group. After the above process， the aorta and serum of mice were taken. The pathological changes of the aortic root were observed by hematoxylin-eosin （HE） staining. The lipid plaques in the aorta were observed by gross oil redness. Serum levels of total cholesterol （TC）， triglyceride （TG）， low density lipoprotein cholesterol （LDL-C）， and high density lipoprotein cholesterol （HDL-C） were detected， and the levels of interleukin-1β （IL-1β） and interleukin-18 （IL-18） were detected by enzyme-linked immunosorbent assay （ELISA）. Western blot and immunohistochemical method were used to analyze the expression of TRPA1， ATP-binding cassette transporter A1 （ABCA1）， ATP-binding cassette transporter G1 （ABCG1）， and mannose receptor （CD206）. ResultFrom the perspective of drug efficacy， compared with the normal group， pathological changes such as plaque， a large number of foam cells， and cholesterol crystals appeared in the aorta of the model group， and the serum levels of TC， LDL-C， IL-1β， and IL-18 were significantly increased （P<0.01）. The HDL-C level was significantly decreased （P<0.01）， and the CD206 level in aortic tissue was significantly decreased （P<0.01）. Compared with the model group， the lipid deposition in the aorta was alleviated in all drug administration groups. In addition， except for the high-dose group of Zhishi Xiebai Guizhitang， all drug administration groups could significantly decrease the levels of TC and LDL-C （P<0.01）. In terms of inflammation， except for the middle-dose group of Zhishi Xiebai Guizhitang， the levels of IL-1β and IL-18 were significantly decreased in all drug administration groups （P<0.05）. Moreover， Zhishi Xiebai Guizhitang could also up-regulate the levels of CD206， and the difference was significant in the middle-dose and high-dose groups （P<0.05）. From the perspective of mechanism， the expression levels of TRPA1， ABCA1， and ABCG1 in the aorta in the model group were lower than those in the normal group （P<0.05）. Compared with the model group， all drug administration groups significantly increased the expression of TRPA1 in the aorta （P<0.05）， and the expressions of ABCA1 and ABCG1 were increased. The differences in the middle-dose and high-dose groups and the simvastatin group were significant （P<0.05）， which was basically consistent with the trend of immunohistochemical results. ConclusionZhishi Xiebai Guizhitang can effectively reduce blood lipid and inflammation levels and inhibit the formation of aortic plaque. The mechanism may be explained as follows： the expressions of ABCA1 and ABCG1 downstream are increased through TRPA1， which promotes cholesterol outflow in foam cells， thereby regulating cholesterol metabolism， intervening in inflammation level to a certain extent， and finally treating AS.

Osteoporosis （OP） is a common bone disease affecting the quality of life and causing huge medical burden to the patients and society. The occurrence of OP is mainly caused by excessive bone resorption and insufficient bone formation， which are directly influenced by external calcium ion balance. Calcium imbalance can impair bone integrity， reduce the calcium supply to the bone， and lower the calcium content in the bone， thus triggering OP. Drugs are the main anti-OP therapy in modern medicine， which， however， may cause adverse reactions and drug dependence. Chinese medicines have good clinical effects and high safety in treating OP， being suitable for long-term use. Recent studies have shown that Chinese medicines can alleviate estrogen deficiency， regulate bone cell and calcium metabolism， which is crucial for the formation and development of OP. The transient receptor potential cation channel superfamily V members 5 and 6 （TRPV5 and TRPV6， respectively） affect bone homeostasis by mediating the transmembrane calcium ion transport in the intestine （TRPV6） and kidney （TRPV5）. Therefore， TRPV5/6 is one of the key targets to understand the anti-OP mechanisms of the effective parts of Chinese medicines， which is worthy of further study. This paper summarizes the research results about the anti-OP effects of Chinese medicines in the last two decades， especially the mechanism of regulating calcium metabolism， aiming to provide new ideas for the basic research， clinical application， and drug development of OP treatment.

ObjectiveTo explore the effect of home exercise on pain, function and quality of life after operation for rotator cuff injury. MethodsFrom June, 2023 to June, 2024, 45 patients after operation for rotator cuff injury were selected from Xuzhou Rehabilitation Hospital Affiliated to Xuzhou Medical University and Xuzhou Central Hospital, and randomly divided into conventional group (n = 15), home-based group (n = 15) and combined group (n = 15). The conventional group received an eight-week routine rehabilitation program in hospital, the home-based group received an eight-week home exercise prescription training, and the combined group first received four weeks of routine rehabilitation in hospital, and followed by four weeks of home exercise prescription training. They were assessed with Visual Analogue Scale for pain (VAS), University of California at Los Angeles shoulder rating scale (UCLA), Constant-Murley Score (CMS), range of motion (ROM) of shoulder, and the Short-form of Health Survey-36 (SF-36) before treatment, and four and eight weeks after treatment. ResultsVAS scores decreased in all the three groups four and eight weeks after treatment (Z > 2.964, P < 0.001), which was the most in the home-based group four weeks after treatment (|Z| > 2.531, P < 0.05). The main effect of time was significant in scores of UCLA, CMS, and physical health and mental health of SF-36 (F > 498.102, P < 0.001), which improved after treatment (P < 0.001). The main effect of group was significant in score of mental health of SF-36 (F = 7.408, P = 0.002), which was the most in the home-based group four and eight weeks after treatment (P < 0.01). The interaction was significant in score of physical health of SF-36 (F = 10.138, P < 0.001), which was the least in the home-based group four weeks after treatment (P < 0.05). The main effect of time was significant in every direction of ROM, which improved after treatment (P < 0.001). The interaction was significant in ROM of abduction and external rotation (F > 4.059, P < 0.01), and almost significant in ROM of flexion (F = 2.412, P = 0.055). However, ROM of flexion was less in the home-based group than in the combined group four weeks after treatment (P = 0.047), which was less in the home-based group than in the conventional group eight weeks after treatment (P = 0.042); ROM of abduction was the least in the home-based group four weeks after treatment (P < 0.01), which was less in the home-based group than in the combined group eight weeks after treatment (P = 0.046); ROM of external rotation was less in the home-based group than in the combined group four weeks after treatment (P = 0.022). ConclusionHome exercise is effective on pain, function and quality of life in patients after operation for rotator cuff injury. There are benefits with both home exercise and institution-based rehabilitation, and almost the same in a whole eight weeks after treatment.

ObjectiveTo investigate the mechanism and effect of Qingfei Paidu decoction on transient receptor potential vanilloid-1/Transient receptor potential ankyrin1 （TRPV1/TRPA1） based on heat-sensitive channel and inflammatory response. MethodAccording to body weight， 80 8-week-old C57BL/6 mice were randomly divided into the normal group， model group， dexamethasone group （5 mg·kg^-1）， and low-dose， medium-dose， and high-dose groups of Qingfei Paidu decoction （14.865， 29.73， 59.46 g·kg^-1）， with 12 mice in each group. In addition to the normal group， the other groups were administered 20 μL （1×10^-3 g·kg^-1） to each mouse by airway infusion to establish the acute lung injury （ALI） model. In the administration group， the drug was given 1 h after modeling and again after an interval of 24 h. The lung tissue was taken 36 h after modeling. Double lung wet/dry weight ratio（W/D）， hematoxylin-eosin （HE） staining， enzyme-linked immunosorbent assay （ELISA）， and Western blot were used to observe and detect the pathological changes of lung tissue， expression levels of inflammatory cytokine tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）， and expressions of TRPV1 and TRPA1 proteins in heat-sensitive channel， nuclear factor kappa-B （NF-κB）， inhibitor of NF-κB （IκBα） in inflammatory pathway， and phosphorylated proteins. The phosphorylated protein/total protein ratio was calculated. ResultCompared with that in the normal group， the lung tissue of mice in the model group was seriously damaged， and pulmonary capillary permeability increased. Alveolar capillary congestion and dilation destroyed the complete structure of the alveolar， and the alveolar wall thickened. A large number of inflammatory cells and red blood cells were infiltrated， and pulmonary edema was significantly aggravated. The expressions of TNF-α， IL-6， TRPV1， TRPA1， phosphorylated NF-κB p65/NF-κB p65， and phosphorylated IκBα/IκBα were significantly increased （P<0.01）， and the whole lung W/D was significantly increased （P<0.01）. Compared with the model group， the dexamethasone group and low-dose， medium-dose， and high-dose groups of Qingfei Paidu decoction could significantly improve pulmonary edema. TNF-α， IL-6， TRPV1， TRPA1， lung tissue NF-κB p65， and IκBα phosphorylated protein/total protein ratio decreased significantly （P<0.05， P<0.01）. The whole lung W/D also decreased significantly （P<0.05， P<0.01）. ConclusionQingfei Paidu decoction has anti-inflammatory and protective effects on LPS-ALI mice， which can effectively reduce inflammation， induce diuresis， and alleviate edema. Its mechanism may be related to the regulation of the expression of TRPA1 and TRPV1 and the inhibition of the activation of the NF-κB pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To compare the safety and clinical efficacy of freehand and 3D printing navigation template assisted screw placement in patients with old odontoid fractures of type Ⅱ.Methods Total of 38 patients with old odontoid fractures of type Ⅱ were treated from November 2018 to December 2022,all of which presented as chronic neck pain.According to the dif-ferent methods of screw insertion into the pedicle,the patients were divided into a navigation template group and a freehand group.In the navigation template group,there were 17 patients including 9 males and 8 females with an average age of(51.30±13.20)years old,disease duration was(22.18±7.59)months.In the freehand group,there 21 patients including 7 males and 14 females with an average age of(49.46±11.92)years old,disease duration was(19.52±9.17)months.The intraoperative blood loss,operation time,and postoperative drainage output were recorded and compared between two groups.The accuracy of screw placement was evaluated by CT scan.Before operation and 1 year after operation,cervical pain was assessed by visual analogue scale(VAS),neurological changes were evaluated by the Japanese Orthopaedic Association(JOA)score,and the de-gree of spinal cord injury was assessed by the American Spinal Injury Association(ASIA)injury scale.Results All patients were followed up for(25.31±1.21)months.The operation time of template group(112.00±20.48)min had significantly shorter than that of the freehand group(124.29±15.24)min(P＜0.05),while there were no significant differences between two groups in terms of intraoperative blood loss,postoperative drainage,and hospital stay(P＞0.05).At 1 year after operation,in template group and freehand group,the VAS[(2.88±0.86),(2.90±0.83)]and JOA[(14.94±1.82),(14.62±2.19)]improved with pre-operative[VAS(4.71±0.92),(4.86±0.79)and JOA(12.18±2.30),(11.95±2.31)](P＜0.05),with no significant difference between two groups(P＞0.05).No significant improvement was observed in ASIA grading in either group at 1 year after opera-tion(P＞0.05),and there was no significant difference between two groups(P＞0.05).The template group had significantly better accuracy of screw placement in the pedicle of the axis than the freehand group(P＜0.05),while no significant difference was observed between two groups in the accuracy of screw placement in the pedicle of the atlas(P＞0.05).Conclusion In the treat-ment of type Ⅱ old odontoid fractures with posterior pedicle screw fixation,3D printing navigation template screw placement can significantly shorten the operation time,achieve similar clinical efficacy as free-hand screw placement,and significantly im-prove the accuracy of screw placement in the pedicle of the axis.

Purpose::Although traditional craniotomy (TC) surgery has failed to show benefits for the functional outcome of intracerebral hemorrhage (ICH). However, a minimally invasive hematoma removal plan to avoid white matter fiber damage may be a safer and more feasible surgical approach, which may improve the prognosis of ICH. We conducted a historical cohort study on the use of multimodal image fusion-assisted neuroendoscopic surgery (MINS) for the treatment of ICH, and compared its safety and effectiveness with traditional methods.Methods::This is a historical cohort study involving 241 patients with cerebral hemorrhage. Divided into MINS group and TC group based on surgical methods. Multimodal images (CT skull, CT angiography, and white matter fiber of MRI diffusion-tensor imaging) were fused into 3 dimensional images for preoperative planning and intraoperative guidance of endoscopic hematoma removal in the MINS group. Clinical features, operative efficiency, perioperative complications, and prognoses between 2 groups were compared. Normally distributed data were analyzed using t-test of 2 independent samples, Nonnormally distributed data were compared using the Kruskal-Wallis test. Meanwhile categorical data were analyzed via the Chi-square test or Fisher’s exact test. All statistical tests were two-sided, and p < 0.05 was considered statistically significant. Results::A total of 42 patients with ICH were enrolled, who underwent TC surgery or MINS. Patients who underwent MINS had shorter operative time ( p < 0.001), less blood loss ( p < 0.001), better hematoma evacuation ( p =0.003), and a shorter stay in the intensive care unit ( p =0.002) than patients who underwent TC. Based on clinical characteristics and analysis of perioperative complications, there is no significant difference between the 2 surgical methods. Modified Rankin scale scores at 180 days were better in the MINS than in the TC group ( p =0.014). Conclusions::Compared with TC for the treatment of ICH, MINS is safer and more efficient in cleaning ICH, which improved the prognosis of the patients. In the future, a larger sample size clinical trial will be needed to evaluate its efficacy.

Background/Aims: Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy. Methods: We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment. Results: The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset. Conclusions Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.
