ObjectiveTo investigate the inhibitory effect of Biejia Decoction Pill on the proliferation， migration， and aerobic glycolysis of hepatocellular carcinoma （HCC） using cell experiments， as well as related mechanisms. MethodsHuman liver cancer cell line Huh7 was selected， and Sprague-Dawley rats were randomly divided into blank serum group， inhibitor group， and high-， middle-， and low-dose Biejia Decoction Pill groups. Rat serum containing the drug was prepared for the incubation of Huh7 cells. CCK8 assay and scratch assay were used to explore the effect of Biejia Decoction Pill on the proliferation and migration of HCC cells； glycolytic rate-limiting enzymes and metabolites were measured to explore the effect of Biejia Decoction Pill on aerobic glycolysis of liver cancer cells； RT-qPCR and Western blot were used to explore the effect of Biejia Decoction Pill on the mRNA expression， related proteins， and phosphorylation of the protein kinase B （AKT）/mammalian target of rapamycin （mTOR） signaling pathway. A one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test or the Dunnett’s T3 test were used for further comparison between two groups. ResultsCompared with the blank serum group， the Biejia Decoction Pill groups had significant reductions in OD value， migration rate during different periods of time， glycolytic rate-limiting enzymes （hexokinase， phosphofructokinase， pyruvate kinase）， and glycolytic metabolites （pyruvate， lactic acid， ATP） （all P<0.05）. RT-qPCR results showed that compared with the blank serum group， the high-， middle-， and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of mTOR， and the high- and low-dose Biejia Decoction Pill groups had a significant reduction in the mRNA expression level of AKT （all P<0.05）. Western blot results showed that compared with the blank serum group， the high-， middle-， and low-dose Biejia Decoction Pill groups had significant reductions in the expression levels of mTOR-related proteins and phosphorylated proteins， and the high- and middle-dose Biejia Decoction Pill groups had significant reductions in the expression levels of AKT-related proteins and phosphorylated proteins （all P<0.05）. ConclusionThis study preliminarily verifies that the serum containing Bijia Decoction Pill can inhibit the aerobic glycolysis of human hepatoma Huh7 cells， thereby inhibiting their proliferation and migration， possibly by inhibiting the expression of the proteins related to the AKT/mTOR signaling pathway.

Objective : To explore the relationship between single nucleotide polymorphisms ( SNPs) in D-loop region of mitochondrial DNA ( mtDNA) and mtDNA copy number and the risk of dermatomyositis ( DM) ，and its in- fluencing factors． Methods : 74 patients with DM and 92 healthy controls were included in the study． Genomic DNA was extracted from peripheral blood and the target fragment of mtDNA D-loop region was amplified by PCR technique，and the products were subsequently sequenced．Serum levels of ROS were assessed using a high-sensi- tivity reactive oxygen species detection kit．The expression levels of cytokines，interleukin ( IL) -5，IL-13，inter- feron-γ ( IFN-γ) ，IL-2，IL-6，IL-10，tumor necrosis factor-α ( TNF-α) and IL-4 were measured using Flow Fluo- rescence Immunmicrobeads Assay．Wilcoxon rank-sum test was used to assess the potential correlation between cy- tokines and SNPs associated with DM risk．The relative copy number of mtDNA was measured using quantitative re- al-time polymerase chain reaction ( qPCR) analysis． Results : Two SNPs ( 16304T / C，16519T / C) were found to be associated with the risk of developing DM，and alleles 16304C ( χ2 = 4. 937，P = 0. 026) and 16519C ( χ2 = 4. 405，P = 0. 036) in the mitochondrial D-loop region were confirmed to be associated with DM development risk． The DM risk-associated allele 16304C was significantly associated with lower IL-4 expression ( P = 0. 016) ．The mtDNA copy number was significantly higher in DM patients than in controls ( P ＜0. 001) ． Conclusion Mitochondrial D-loop SNPs can be potential biomarkers for DM risk，and SNPs may be involved in DM by influencing cytokines．DM shows high expression of mtDNA copy number，and the increase in mtDNA copy number may lead to mitochondrial dysfunction，which triggers the pathogenesis of DM．

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To analyze the trabecular bone score (TBS) and its association with muscle health in the postmenopausal population.Methods:It was a cross-sectional study. A total of 214 postmenopausal individuals who underwent dual-energy X-ray absorptiometry testing at the Beijing Research Institute of Sports Science between January and December 2023 were consecutively included. The participants were divided into two groups based on the presence or absence of osteoporosis (OP): 62 cases in the OP group and 152 cases in the non-OP group. All subjects completed body composition assessments and scans of bilateral hip and lumbar spine bone mineral density (BMD)(All the BMD in this study were areal BMD). Demographic data, including age, age at menarche, age at menopause, and fracture history, were also collected. TBS was calculated using the TBS iNsight software. Muscle health indicators included upper limb, lower limb, trunk, and total muscle mass, lean body mass, appendicular skeletal muscle mass index (ASMI), and grip strength. The Pearson correlation analysis was used to determine the relationship between TBS and muscle health indicators, as well as between TBS and the BMD of lumbar spine (L 1-4). Further, multiple linear regression analysis was conducted to explore the independent association between TBS and muscle health indicators. Results:TBS, lean body mass, ASMI, grip strength, and muscle mass of the upper limb, lower limb, trunk, whole body in the OP group were all lower than those in the non-OP group [(1.27±0.07) vs (1.35±0.07) score, (36.64±3.45) vs (39.14±3.62) kg, (6.16±0.56) vs (6.44±0.63) kg/m2, (23.87±3.31) vs (25.34±4.33) kg, (3.54±0.47) vs (3.78±0.47) kg, (11.70±1.33) vs (12.68±1.49) kg, (16.57±1.68) vs (17.50±1.69) kg, and (34.91±3.33) vs (37.13±3.47) kg] (all P<0.05). Pearson analysis showed that TBS was positively correlated with lean body mass, ASMI, grip strength, and muscle mass of the upper limb, lower limb, whole body (all P<0.05). TBS was negatively correlated with age ( P<0.01). TBS was positively correlated with the BMD of lumbar spine (L 1-4) ( r=0.660, P<0.01). Multiple regression analysis demonstrated that ASMI was positively correlated with TBS ( β=0.284, P<0.01). Conclusion:In the postmenopausal population, individuals with OP have lower TBS. Furthermore, TBS is closely associated with muscle health.

Natural herbs demonstrate significant therapeutic potential in managing chronic and complex diseases; however, their clinical application faces limitations due to low bioavailability, instability, toxicity, and herb-drug interactions. Furthermore, insufficient standardized evidence and global acceptance impede their widespread adoption. Liposomes, nanocarriers consisting of a phospholipid bilayer enclosing an aqueous core, present a promising approach for enhancing the pharmacokinetics and therapeutic efficacy of herbal compounds. These adaptable systems can encapsulate both hydrophilic and hydrophobic agents, enabling targeted drug delivery and enhanced stability. Moreover, liposomes can be modified to carry diagnostic and imaging agents, enabling precise disease detection and monitoring. While liposomes offer potential as an innovative delivery technology for herbal remedies, their application in Traditional Chinese Medicine (TCM) remains relatively unexplored. TCM, with its holistic, energy-based approach to health and organ function, presents distinct challenges regarding formulation and delivery. This review examines the therapeutic potential of herbal medicines, emphasizing how liposomes address delivery challenges within the TCM framework. It also investigates the integration of TCM with Western medical practices, demonstrating how liposomal systems may bridge these approaches. The review analyzes key formulation techniques for TCM-loaded liposomes, particularly the microfluidic method, which demonstrates superior control over particle size and encapsulation efficiency compared to conventional methods. The analysis addresses barriers to integrating liposomal delivery systems with TCM, including physicochemical properties, scalability issues, and regulatory challenges. Finally, this review provides strategic recommendations for overcoming these obstacles and identifies future research directions to maximize the potential of liposomal technology in enhancing TCM therapies.

Objective To observe the clinical effect of Huangqi Yixin Decoction combined with sacubitril/valsartan in treatment of patients with heart failure with preserved ejection fraction(HFpEF)of Qi deficiency and blood stasis type.Methods A total of 86 patients with HFpEF of Qi deficiency and blood stasis type were randomly divided into western medicine group and combination group using the random number table method,with 43 cases in each group.The western medicine group was trea-ted with sacubitril/valsartan sodium tablets on the basis of conventional anti-heart failure therapy,while the combination group was additionally treated with Huangqi Yixin Decoction on the basis of the western medicine group's treatment.The therapeutic efficacy,traditional Chinese medicine(TCM)syndrome scores,cardiac function indicators[Tei index,N-terminal pro-brain natriuretic peptide(NT-proBNP)],exercise tolerance[6-minute walk distance(6MWD),maximum exercise heart rate,metabolic equivalent(MET)],and the occurrence of adverse reactions were compared between the two groups.Results The overall clinical effective rate in the combination group was 93.02％,which was higher than that in the western medicine group(76.74％),and the difference was statistically significant(P＜0.05).After treatment,the TCM syndrome scores in both groups were lower than those before treatment,and the scores in the combination group were lower than those in the western medicine group,with a statistically significant difference(P＜0.05).After treatment,the levels of Tei index and NT-proBNP in both groups were lower than those before treatment,and the levels in the combination group were lower than those in the western medicine group,with a statistically sig-nificant difference(P＜0.05).After treatment,the 6MWD,maximum exercise heart rate,and MET in both groups were higher than those before treatment,and the values in the combination group were higher than those in the western medicine group,with a statistically significant difference(P＜0.05).The incidence of adverse reactions in the western medicine group was 18.60％,which was higher than that in the combination group(4.65％),and the difference was statistically signifi-cant(P＜0.05).Conclusion Huangqi Yixin Decoction combined with sacubitril/valsartan has a good therapeutic effect on HFpEF of Qi deficiency and blood stasis type.It can reduce the TCM syn-drome scores of patients,improve exercise tolerance,and has good safety.

Objective:To investigate the protective effects of resveratrol (RSV) on human sperm cryopreservation and explore its underlying protective mechanisms.Methods:A total of 165 normal fresh semen samples were collected from the Reproductive Medicine Center, Department of Obstetrics and Gynecology and Human Sperm Bank of the First Affiliated Hospital of Anhui Medical University between December 2022 and December 2024. Among them, 65 samples were used to obtain semen parameters before and after conventional freezing. Each sample of the other 104 samples was mixed at a 2∶1 volume ratio with cryoprotectant containing 0, 10 -?, 10 -?, or 10 -? mol/L RSV, followed by cryopreservation in liquid nitrogen for 24 h. Post-thaw assessments included routine sperm parameters, sperm DNA fragmentation index (DFI) evaluated by sperm chromatin dispersion assay, reactive oxygen species (ROS) levels measured via flow cytometry, RSV and nuclear factor erythroid 2-related factor 2 (NRF2) interactions examined by molecular docking and cellular thermal shift assay (CETSA), NRF2 protein contents analyzed by immunofluorescence and Western blotting, mRNA levels of NRF2 and downstream antioxidant proteins Heme Oxygenase-1 (HO-1) and NAD(P)H: quinone oxidoreductase 1 (NQO1) quantified by qRT-PCR and effects of NRF2 inhibitor ML385 on sperm parameters. Results:Compared with fresh samples, conventional cryopreservation significantly reduced sperm motility (all P<0.001). The addition of 10 -? mol/L RSV significantly improved the percentage of forward motile sperm after freezing (26.98%±8.98% vs. 19.61%±8.03%, P<0.001) while reducing DFI (9.84%±3.81% vs. 15.06%±4.22%, P<0.001) and ROS levels ( P<0.001) compared with the post-freezing group without the addition of RSV. Both molecular docking analysis and CETSA confirmed that RSV interacted with NRF2. Notably, sperm cryopreserved with 10 -? mol/L RSV exhibited significantly higher contents of NRF2 and its downstream effectors HO-1 and NQO1 compared with the post-freezing group without the addition of RSV (all P<0.001). This protective effect was markedly attenuated by co-treatment with the NRF2 inhibitor ML385, as evidenced by a significant decline in sperm motility ( P<0.001). Conclusion:RSV exerts cryoprotective effects likely through NRF2-mediated antioxidant pathways, reducing oxidative stress and enhancing post-thaw sperm quality.

Objective Construction and Practice of a Whole-Process Digitalized Hemodialysis Management System.Methods ① Integrate device data through the Internet of Things(IoT)to enable automatic collection of dialysis parameters and real-time validation of quality control rules.② Build an"intelligent error prevention system"based on Data Analysis,realizing the transformation from patient management to digital quality control management in hemodialysis treatment.③ Implement a closed-loop management system for the entire patient dialysis process.Results The system reduced clinicians' time spent manu-ally filling and verifying documentation by 75％,and increased the adequacy compliance rate for maintenance dialysis patients to 100％per quarter and other goals.Conclusion Traditional hemodialysis management relies on manual records,leading to issues such as fragmented data,delayed quality control,material waste,and high risks of hospital-acquired infections.The entire process,from patient appointment to post-dialysis summary management lacks coordination,and manual calculation of key indica-tors is prone to errors,with insufficient timeliness in quality surveillance warnings.The construction of an information system can break down operational silos and enable"data-driven decision-making",and provides a replicable model for the digital manage-ment of hemodialysis.
