Objective: To compare the correlation and difference of body type index and physical forms of the Wa nationality in China and Myanmar across different age groups and genders, and to clarify the body type characteristics of the Wa nationality in China and Myanmar. Methods: The Heath-Carter somatotype evaluation method was used to determine and evaluate the body types of 508 Wa people (326 males and 182 females) from China and 368 Wa people (242 males and 126 females) from Myanmar. Results: The average body size values of Chinese and Burmese Wa males were 2.3-5.6-2.7 and 2.2-5.7-3.5, respectively. The average body size values of Chinese and Burmese Wa females were 4.3-5.2-2.1 and 4.2-5.4-2.4, respectively. The endomorphic component values of Chinese Wa males and females were slightly higher than those of Myanmar Wa nationality, while the mesomorphic and ectomorphic component values were lower than those of Myanmar Wa nationality. For males in both groups, there were no significant differences in the three somatotype components across different age groups. Similarly, for females, there were no significant correlations in the three somatotype components across age groups. However, bone development, muscle strength, fat and linearity of the body were significantly different across different age groups, showing statistical significance. There was no significant difference in average somatotype values between the Wa nationality in China and Myanmar. Conclusion: The male of Sino-Burmese Wa nationality has higher linearity and slender body shape. The female of Sino-Burmese Wa nationality have a more pronounced distribution of subcutaneous fat, resulting in a more curvaceous physique. Overall, males predominantly exhibit a mesomorphic ectomorphic somatotype, while females predominantly exhibit a mesomorphic endomorphic somatotype.

The traditional view holds that bone tissue lacked lymphatic vessels, but recent studies utilizing advanced imaging techniques have confirmed the presence of functional lymphatics in bone, joints, and intervertebral discs. The lymphatic system plays a crucial role in bone homeostasis and repair by clearing metabolic waste and coordinating the immune microenvironment. Pathological inflammation can remodel lymphatic function, and targeting lymphatics (e.g., modulating VEGF-C signaling) has shown potential to promote bone regeneration in animal models. Such findings have overturned traditional understanding, providing novel perspectives for understanding bone repair mechanisms and developing new therapies for bone and joint disorders.

Objective: To explore the effects of protocatechuic acid (PCA) on bone metabolism and Yes-associated protein 1/acyl-CoA synthetase long-chain family member 4/lysophosphatidylcholine acyltransferase 3 (YAP/ACSL4/ LPCAT3)-mediated ferroptosis in a rat model of steroid-induced osteonecrosis of the femoral head (SONFH). Methods: The SONFH model of rats was prepared and randomly divided into the control group, the SONFH group, and the Liproxstatin-1 (ferroptosis inhibitor) group, the low-dose PCA (PCA-L) group, the high-dose PCA (PCA-H) group, and the PCA-H+Verteporfin (YAP activator) group based on the SONFH model. Serum Ca, P, total iron ion concentrations, bone metabolism and oxidative stress levels were detected. Flow cytometry was applied to detect the level of reactive oxygen species (ROS). Micro-CT was performed to observe the femoral morphology. Transmission electron microscopy was employed to observe the ultrastructural changes in femoral head, H-E staining was utilized to observe the pathological changes in femoral head. Immunohistochemistry was used to detect the expressions of ferroptosis-related proteins in femoral head. Western blotting were adopted to detect the expressions of YAP1, ACSL4 and LPCAT3 in femoral head. Results: Compared with the control group, the SONFH grouphad severe pathological damage of the femoral head. The Ca, P, osteoprotegerin (OPG), OPG/receptor activator of nuclear factor-κB ligand ratio, glutathione, level glutathione peroxidase 4 and solute carrier family 7 member 11 expressions were decreased, while the total iron concentration, RANKL, malondialdehyde, ROS content, and YAP1, ACSL4, and LPCAT3 expressions were increased. Liproxstatin-1, PCA-L and PCA-H groups significantly improved the pathological damage of the femoral head and reversed the trend of the above indicators. Verteporfin treatment partially reversed the improvement effect of PCA-H treatment on bone metabolism in SONFH rats. Conclusion: PCA can improve bone metabolism in SONFH rats by inhibiting the YAP/ACSL4/LPCAT3 pathway-mediated ferroptosis.

Human anatomy has emerged from humanity’s practical exploration of the human body. Anatomy has played an irreplaceable role in the advancement of medicine, from the mummification practices of ancient Egypt to Leonardo da Vinci’s anatomical sketches during the Renaissance, from Vesalius’s De humani corporis fabrica to modern digital anatomical atlases. The history of this discipline not only reflects continuous innovations in science and technology but also embodies the deepening of human self-understanding. However, with the rapid advancement of modern medicine, traditional anatomical research faces many challenges, and its role and future direction within the medical system have sparked widespread academic reflection. Based on the realities of traditional anatomy and integrating historical evolution with contemporary medical needs, this article explores new pathways for anatomical research. It emphasizes the critical value of clinical applied anatomy, analyzes the synergistic relationship between human anatomy and surgery, and envisions future directions for anatomical research empowered by modern technologies, thereby providing insights for innovative development in the field.

The lumbar intervertebral foramen serves as a critical access route in posterolateral minimally invasive spinal surgery, transmitting vital neurovascular structures such as nerve roots and blood vessels, and is characterized by complex anatomical relationships. Damage to these structures during surgical procedures may lead to severe complications. Therefore, a deep understanding of the regional anatomy of the lumbar intervertebral foramen is crucial for percutaneous endoscopic surgery. This article reviews the bony structure of the intervertebral foramen, the definition and measurement of the Kambin ’s safe triangle, the course of intraframinal nerve roots and th e classification of ganglia, as well as the distribution characteristics of ligaments and blood vessels, with the aim of discussing how this anatomical knowledge can promote the selection of surgical approaches, the improvement of specialized instruments, and the avoidance of operational risks, thereby providing an anatomical basis for the precise application of this technique.

Objective: To systematically delineate the afferent and efferent connectivity patterns of temporal association cortex (TeA), with particular focus on elucidating its divergent upstream inputs relative to primary auditory cortex (Au1). Methods: Using adult C57BL/6J wild-type mice, we performed bidirectional viral tracing through stereotaxic injections. For retrograde tracing, AAV2/retro-hSyn-mCherry was injected into either TeA or Au1 to label and quantify upstream input neurons. For anterograde tracing, HSV1-H129 was injected specifically into TeA to map and quantify its downstream projection targets. Results: Both Au1 and TeA received extensive upstream inputs, including ipsilateral and contralateral auditory cortices, thalamus and other cortical regions. Compared with Au1, TeA received more inputs from the limbic system and entorhinal cortex. Downstream projections showed that TeA targeted auditory cortex, auditory thalamus, amygdala, pontine nuclei and other brain regions. Conclusion: In contrast to Au1, TeA, as a multisensory integration hub, receives more inputs from the limbic system and cerebral cortex, and widely projects to brain regions related to emotion, movement and sensory regulation, suggesting its potential key role in sensory-motor integration networks.

Objective: To investigate whether melatonin can alleviate ferroptosis induced by RAS-selective lethal small molecule 3 (RSL3) in AML12 cells and the role of melatonin receptor 1 (MT1) in the process. Methods: A ferroptosis model of AML12 cells was established via RSL3 induction. Cell viability was assessed by CCK-8 staining. Intracellular ferrous ion (Fe2+), reactive oxygen species (ROS), and lipid peroxidation levels were detected through fluorescent probe staining. Expressions of MT1 and ferroptosis-related proteins, namely long-chain acyl- CoA synthetase 4 (ACSL4) and glutathione peroxidase 4 (GPX4), were measured by Western blotting. The impact of MT1 knockdown on the effects of melatonin was observed using the broad-spectrum receptor antagonist of melatonin, N-acetyl-2-benzyltryptamine (Luz) and small RNA interference technology. Results: After RSL3 induction, AML12 cell viability decreased, GPX4 expression was reduced, and ACSL4 expression was increased, along with elevated levels of intracellular Fe2+, ROS, and lipid peroxidation. Melatonin pretreatment antagonized the changes in cell viability, ferroptosis-related proteins, intracellular Fe2+, ROS, and lipid peroxidation. RSL3 induction led to a decrease in MT1 expression in AML12 cells, which was rescued by melatonin administration. Luz and MT1 knockdown could both antagonize the protective effect of melatonin on AML12 cell ferroptosis. Conclusion: Melatonin may alleviate RSL3-induced ferroptosis in AML12 cells via MT1.

The protective effect of exercise on the heart and its benefits in promoting cardiovascular health have been widely recognized. Exercise induces physiological hypertrophy of the myocardium, improves mitochondrial metabolism and function, regulates the balance of the cardiovascular autonomic nervous system. These mechanisms enhance cardiovascular fitness, improves cardiovascular metabolism and function, and reduce the risk of various cardiovascular diseases, playing a positive biological role in disease prevention and treatment. Exercise also has a beneficial health effect on the structure and function of the cardiovascular system by promoting the secretion of related exercise factors, inducing and activating related signaling pathways, improving insulin sensitivity and metabolism of the cardiovascular system, and enhancing antioxidant capacity. Studying the mechanisms of exercise-mediated benefits on cardiovascular structure and function and its role in disease prevention and treatment offers valuable theoretical insights for designing effective exercise-based health promotion strategies and holds great promise for clinical applications.

Objective: To investigate the existence, morphological characteristics and function of the apical ligament of the coronoid process in the elbow joint through integrated anatomical, histological and imaging analyses. Methods: Ten frozen elbow joints from cadavers were dissected to measure the coronoid process and to isolate capsulo-ligamentous structures. The collagen fiber structure of the joint capsule was analyzed by tissue staining and sectioning. The CT images from 20 patients with elbow joint fractures were collected. Having been reconstructed on the three-dimensional images, the height and width of the coronary process, and the distance between the fracture fragment and the humeral trochlear were measured. Results: Anatomical studies showed that white connective tissue attached to the cartilaginous surface of the coronoid process. Histological sections, scanned through CaseViewer 2.4 software, showed ligament-like tissue attached to the bony tissue of the coronoid, with an attachment point thickness of (1.86±0.45) mm. The imaging analysis indicated that the height of the coronoid process fracture was (7.68±3.54) mm, the linear distance from the fracture to the humerus was (3.18±0.87) mm, and the distance from the fracture to the midpoint of the olecranon was (14.57±3.32) mm. According to the Regan Morrey classification, there were 14 type Ⅰ , 4 type Ⅱ , and 2 type Ⅲ fractures. There was no significant correlation between the distance from the fracture fragment to the humerus and the fragment height or distance to the olecranon midpoint. Conclusion: Anatomical and histological analyses revealed the presence of a ligament-like structure within the anterior aspect of the coronoid process capsule. Imaging evaluations demonstrated no significant correlation between the linear distance from the fracture fragment to the humeral axis, the height of the fracture fragment, and its distance to the midpoint of the olecranon. Furthermore, a distinct ligamentous attachment was identified at the tip of the ulnarcoronoid process, herein termed the apical ligament. These findings contribute to a refined understanding of coronoid tip anatomy, support the standardization of treatment strategies for coronoid tip fractures, and enhance postoperative rehabilitation while reducing the risk of complications.

Objective: To investigate the effect of miR-488-3p targeting pentraxin 3 (PTX3) on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). Methods: QRT-PCR was used to detect the expression of miR-488-3p and PTX3 mRNA in undifferentiated and differentiated BMSCs. BMSCs were divided into seven groups: control group, inhibition control group, miR-488-3p inhibition group, overexpression control group, PTX3 overexpression group, miR-488-3p inhibition+si-NC group, and miR-488-3p inhibition+si-PTX3 group. QRTPCR was applied to detect the expression of miR-488-3p and the mRNA expression of PTX3, Runt-related transcription factor 2 (Runx2), osterix, osteocalcin (OCN), and osteopontin (OPN) in BMSCs. CCK-8 was used to detect the viability of BMSCs. The activity of alkaline phosphatase (ALP) and the degree of ALP staining in BMSCs were detected. Alizinin red staining was adopted to detect calcium deposition levels and OD570 in BMSCs. Western blotting was employed to detect the protein expression levels of Runx2, osterix, OCN, OPN, and PTX3. Additionally, the relationship between miR-488-3p and PTX3 was verified. Results: In differentiated BMSCs, the expression of miR-488-3p was downregulated, while the expression of PTX3 mRNA was upregulated. Either inhibiting miR-488-3p or overexpressing PTX3 significantly increased the expression level of PTX3 mRNA, BMSC viability, ALP activity, degree of ALP staining, calcium deposition level, OD570, as well as the mRNA and protein expression levels of Runx2, osterix, OCN, and OPN in BMSCs. Silencing PTX3 reversed the promoting effect of miR-488-3p inhibition on the osteogenic differentiation of BMSCs. Moreover, miR-488-3p was found to target and regulate the expression of P TX3. Conclusion: Inhibition of miR-488-3p may promote osteogenic differentiation of BMSCs by upregulating of PTX3.

Objective: To observe the clinical anatomical features of the superior rectal artery (SRA) under digital subtraction angiography (DSA) and provide an anatomical basis for transvascular interventional therapy in hemorrhoidal disease. Methods: Non-hemorrhoid volunteers undergoing vascular interventional therapy were enrolled. A total of 24 volunteers (12 males and 12 females) were included. SRA imaging data were obtained through DSA to analyze clinical characteristics, SRA origin, initiation, morphology, branching patterns, and distribution. Results: The SRA trunk and branches appeared with complete visualization. The primary branching pattern was bifurcation type (left and right branches from the main trunk), accounting for 87.5%. Morphological subtypes based on terminal branches were as follows: type 22 (left 2, right 2 branches): 29.2%; type 12 (left 1, right 2 branches): 25.0%; type 31 (left 3, right 1 branch): 8.3%; type 13 (left 1, right 3 branches): 13.0%; type 21 (left 2, right 1 branch) and type 23 (left 2, right 3 branches): 8.3% each; type 14 (left 1, right 4 branches) and type 32 (left 3, right 2 branches): 4.2% each. The mean numbers of secondary, tertiary, and quaternary branches before reaching the anorectal junction were (3.9±1.3), (3.5±1.9), and (1.5±2.2), respectively. At the anorectal junction, the average number of branches was (5.5±1.3), and at the dentate line, the average number of branches was (2.3±1.1), with (1.0±0.7) on the left side and (1.4±0.7) on the right side. Conclusion: DSA-based clinical anatomy of the SRA and its branches better evaluates its origin, initiation, morphology, branching patterns, and distribution. These findings provide critical references for selecting target vessels and embolic agent dosage in superselective arterial embolization ablation, as well as offer theoretical support for optimizing procedural protocols.

Objective: To explore the feasibility of the second sacral vertebrae (S2) pedicle screw fixation and provide anatomical basis for its placement. Methods: Adult cadaveric lumbosacral specimens were selected, and parameters including screw trajectory length and lateral angulation angle were measured. Results: The lateral trajectory length was (26.87±4.28) mm, with a lateral angulation angle of (29.26±7.87)°; the medial trajectory length was (34.69±5.60) mm, with a lateral angulation angle of (44.81±4.74)°. Conclusion: S2 pedicle screw fixation is feasible with an appropriate lateral angulation ang le.

Objective: To explore the anatomical features of the posterior distal tibia and to design a bone plate based on three-dimensional reconstruction. Methods: Computed tomography (CT) data of the distal tibia and fibula from 57 healthy adults (30 males, 27 females; 30 left, 27 right; mean age, 42.9 years) were retrospectively analyzed. Fortynine parameters across nine groups were measured, and differences between sexes and sides were assessed by using the t test or Mann–Whitney U test. Results: Twelve parameters showed significant sex differences (e.g., HPS, ∠ A0, ∠ CAPM35, DOC35, ∠ B2), and seven parameters exhibited significant side differences ( ∠ A0, ∠ CAPM25, ∠ B1, h2–h4). Transverse sections revealed that the posteromedial ridge transitions from a sharp angle distally to a blunt arc proximally, with DOC and ∠ CAPM describing the blunt segment. Sagittal section analysis showed that, posterior malleolar height (h) displayed a wave-like pattern, peaking in zone 3 and reaching a minimum in zone 5. The posterior malleolar arc parameters ( ∠ P, d, rad) progressively decreased from distal to proximal. Notable individual variations were observed, with a small proportion of posterior malleoli tending to be flatter and showing markedly larger arc radii than in other individuals. Conclusion: The posterior distal tibia demonstrates quantifiable anatomical characteristics that are partly influenced by sex and side. Three-dimensional measurements provide a basis for the individualized design of helical-surface fixation plates and may offer innovative strategies for the surgical management of posterior malleolar fractures.

Objective: To analyze the impacts of quercetin on lipopolysaccharide (LPS)-induced osteoblast apoptosis and bone morphogenetic protein 2 (BMP2)/Runt-related transcription factor 2 (Runx2) pathway. Methods: Mouse osteoblast MC3T3-E1 cells were cultured in vitro and randomly divided into control group (untreated), LPS group (500 ng/mL LPS treatment), and low-, medium- and high-dose quercetin groups (added 10, 25, 50 μmol/L quercetin on the basis of LPS group). The proliferation of MC3T3-E1 cells was detected by CCK-8 assay. Apoptosis of MC3T3-E1 cells was detected by flow cytometry. Alizarin red staining was applied to measure the relative proportion of cell mineralized nodules. Alkaline phosphatase (ALP) kit was adopted to measure cellular ALP activity. ELISA method was performed to measure the levels of type Ⅰ collagen, inflammatory factors tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) of cells in each group. Western blotting was employed to measure the levels of BMP2/Runx2 pathway and apoptosis-related proteins in MC3T3-E1 cells in each group. Results: The cell proliferation inhibition rate, apoptosis rate, levels of TNF-α, IL-6, as well as the protein levels of Bax and cleavedcaspase- 3 of MC3T3-E1 cells in LPS group at 48 h were higher than those of control group, while the relative proportion of mineralized nodules, ALP activity, and the protein levels of collagen type Ⅰ , BMP2, Runx2 and Bcl-2 were lower than those of control group. The cell proliferation inhibition rate, apoptosis rate, levels of TNF-α, IL-6, as well as the protein levels of Bax and cleaved-caspase-3 of MC3T3-E1 cells in the low-, medium- and highconcentration quercetin groups at 48 h were lower than those of the LPS group, while the relative proportion of mineralized nodules, ALP activity, and the protein levels of collagen type Ⅰ , BMP2, Runx2 and Bcl-2 were higher than those in the LPS group, and these effects were dose-dependent. Conclusion: Quercetin may inhibit LPS-induced osteoblast apoptosis and inflammatoryresponse by activating the BMP2/Runx2 pathway, and antagonize the inhibitory effect of LPS on osteogenic differentiation.

Objective: To investigate the inhibitory effect of Empagliflozin on human renal clear cell adenocarcinoma cells and its related mechanisms. Methods: Bioinformatics analysis was used to screen differential genes and pathways. In vitro experiments were conducted using 786-O cells, which were divided into a control group and an Empagliflozin group (combined with the AMPK inhibitor BAY-3827 or agonist Nilotinib). Western blotting and q-PCR were used to detect the expression of AMPK, PTEN, HDAC11, YAP, BRD4 proteins and epithelial-mesenchymal transition (EMT) markers. Scratch and Transwell assays were performed to evaluate cell migration and invasion capabilities. A nude mouse tumorigenesis experiment was conducted to validate the regulatory role of the AMPK pathway. Results: Bioinformatics analysis screened 1384 differentially expressed genes (800 up-regulated, 584 downregulated), enriched in PI3K-Akt, chemokines and Rap1 pathway; Engleretin significantly up-regulated p-AMPK, PTEN, HDAC11, while inhibiting YAP/BRD4 nuclear expression; down-regulated Snail, Slug mRNA, and enhanced E-cadherin expression; Emgleretin reduced cell migration and invasion, which were reversed by BAY-3827 but further inhibited by Nilotinib. In vivo studies showed Empagliflozin suppressed tumor growth, with AMPK-KD mice exhibiting larger tumor and AMPK-OE mice smaller tumors. Conclusion: Empagliflozin inhibits the progression of renal clear cell adenocarcinoma by activating the AMPK/PTEN/HDAC11 pathway, suppressing YAP/BRD4 nuclear localization and the EMT process, providing new mechanistic insights for clinical treat ment.

Objective: To explore the mechanism by which Ras-related protein Rab-11A (Rab11a) promotes the invasion and metastasis of colorectal cancer (CRC) through its regulation of protein kinase B (AKT) expression and subsequent effects on the Hippo signaling pathway . Methods: Western blotting was employed to detect the expression levels of Rab11a, phosphorylated AKT (p-AKT), phosphatase and tensin homolog (PTEN), nuclear Yes-associated protein (YAP), nuclear activator protein 1 (AP-1), cadherin 2 (CDH2), and microtubule-actin crosslinking factor 1 (MACF1). Wound healing, colony formation, flow cytometry, and Transwell assays were conducted to evaluate the proliferation and migration capabilities of SW480 cells. A nude mouse tumor model was established to assess the impact of Rab11a on tumor growth. Results: Bioinformatics analysis revealed that the expression of Rab11a was significantly higher in colorectal cancer tissues compared with normal tissues, and exhibited significant correlations with the expression of PTEN, AKT, YAP, and AP-1. Experiment results demonstrated that inhibition of Rab11a significantly reduced the expression of p-AKT, nuclear YAP, and nuclear AP-1, while increasing the expression of PTEN. Furthermore, Rab11a knockdown significantly attenuated the migration, proliferation, and invasion of colorectal cancer cells. The nude mouse tumor model further confirmed that overexpression of Rab11a significantly promoted tumor growth, whereas interventions targeting PTEN and YAP suppressed this effect. Conclusion: Rab11a can promote colorectal cancer invasion and metastasis through AKT-mediated inhibition of Hippo pathway.

Nuclear receptor coactivator 4 (NCOA4), a key protein in the regulation of intracellular iron homeostasis, has garnered increasing attention for its role in mediating ferroptosis during intervertebral disc degeneration (IVDD). IVDD is a degenerative condition characterized by nucleus pulposus cell senescence and degradation of the extracellular matrix. This article systematically reviews the molecular mechanisms by which NCOA4 triggers ferroptosis via the ferritinophagy pathway and focuses on the potential roles of NCOA4-associated signaling pathways in regulating iron metabolism dysregulation, oxidative stress, and nucleus pulposus cell apoptosis within the IVDD process. The aim of this review is to provide new insights for tar geted therapies of IVDD.

Objective: To explore the effects of safflower yellow (SY) on the angiogenesis and fracture healing in osteoporotic fracture (OPF) rats through activation of the hypoxia-inducible growth factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF) signaling pathway. Methods: An ORF model of rats was established and randomly divided into five groups: sham operation group, model group, SY group (15.75 mg/kg), inhibitor group (HIF-1α inhibitor-digoxin, 0.05 mg/kg), SY (15.75 mg/kg) + inhibitor (0.05 mg/kg) group. After the administration, X-ray examination was conducted to assess the fracture and healing status of the rats; the changes in bone mineral density (BMD) and bone mineral content (BMC) in callus tissue were detected; H-E staining was used to observe the histopathological changes in rat callus tissue; ELISA was performed to detect the levels of serum biochemical indicators of rats-bone morphogenetic protein-2 (BMP-2) and insulin-like growth factor-1 (IGF-1); Western blotting and RT-qPCR were employed to determine the expression of HIF-1α and VEGF proteins and mRNA in rat callus tissue. Results: Compared with the sham operation group, the model group exhibited clear fracture lines, less callus growth and no connection, disorganized and sparse bone trabeculae, a few osteoblasts and newly formed blood vessels. The fracture healing score, BMD, BMC, HIF-1α, VEGF protein and mRNA expression, BMP-2, and IGF-1 levels were significantly reduced. Compared with the model group, the histopathological changes in the callus tissue and fracture healing of the rats in the SY group were improved, with fracture healing score, BMD, BMC, HIF-1α, VEGF protein and mRNA expression, BMP-2,and IGF-1 levels significantly increased. Compared with the model group, the inhibitor group showed poorer histopathological changes in the callus tissue and the fracture healing, with significant reductions in fracture healing score, BMD, BMC, HIF-1α, VEGF protein and mRNA expression, BMP-2, and IGF-1 levels. Compared with the SY group, the fracture healing score, BMD, BMC, HIF-1α, VEGF protein and mRNA expression, BMP-2, and IGF-1 levels in the SY + inhibitor group were significantly reduced. Conclusion: SY can promote angiogenesis at the fracture site, improve the morphology of bone tissue in osteoporotic rats by activating the HIF-1α/VEGF signaling pathway, thereby accelerating the process of fracture healing.

Objective: To investigate the effect of propofol on osteogenic differentiation of rat osteoblasts and its possible mechanism. Methods: Osteoblasts isolated from neonatal SD rat calvariae were induced to differentiate and were divided into control (differentiation induction only), propofol (12.5, 25.0, and 50.0 μmol/L), and propofol+ phosphatidylinositol 3-kinase (PI3K) inhibitor (LY294002) groups (50.0 μmol/L propofol+10.0 μmol/L LY294002). After 7 d of culture, RT-qPCR was used to detect the mRNA expression levels of alkaline phosphatase (ALP), osteocalcin (OCN), osteopontin (OPN), Runt-related transcription factor 2 (RUNX2), and osterix (Osx) genes in osteoblasts. The expressions of OCN, OPN, RUNX2 and Osx proteins were detected by immunofluorescence staining. Western blotting was performed to detect PI3K, p-PI3K, protein kinase B (AKT), p-AKT, and B-cell lymphomaextra large (Bcl-xL) proteins. ALP staining was adopted after 14 days of cultivation to detect the positivity rate of ALP in rat osteoblasts. After 21 days of cultivation, Alizarin red staining was applied to detect the mineralized nodule formation of rat osteoblasts. Results: After the treatment of propofol with different concentrations, the ALPpositive rate of osteoblasts, mineralized nodule formation, mRNA levels of ALP, OCN, OPN, RUNX2 and Osx, immunofluorescence intensity of OCN, OPN, RUNX2 and Osx, as well as the ratios of p-PI3K/PI3K and p-AKT/AKT and the expression of Bcl-xL were increased. LY294002 attenuated the effects of 50.0 μmol/L propofol on osteogenic differentiation of rat osteoblasts. Conclusion: Propofol promotes osteogenic differentiation of rat osteoblasts, and its mechanism of action may be associated with the activation of th e PI3K/AKT/Bcl-xL signaling pathway.

Objective: To investigate the effect of artesunate (ART) on pain response in lumbar intervertebral disc degeneration (IVDD) rats by regulating the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. Methods: SD rats were used to establish a lumbar IVDD model by acupuncture of the annulus fibrosus, and then random ly divided into model group, low-dose ART group, high-dose ART group, and hi ghdose ART + DUSP19 (JAK2/STAT3 activator) group. Another healthy SD rats were taken as the sham surgery group. After intervention with ART and DUSP19, lumbar spine sagittal T2-weighted MRI scans were performed, and the degree of intervertebral disc degeneration was assessed by using the Pfirrmann grading system. The Von Frey pain threshold test and the tail suspension test were applied to detect pain symptoms in rats. The open field test was used to test the motor ability of rats. H-E staining was applied to detect the morphological changes of lumbar intervertebral disc tissue of rats in each group. ELISA was applied to measure the levels of inflammatory factors such as granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-1β in the serum and lumbar disc tissue of rats in each group. Western blotting was applied to detect the expression and phosphorylation levels of JAK2 and STAT3 in the lumbar disc tissue of rats in each group. Results: Compared with the sham surgery group, the Pfirmmann score, tail suspension test bending time, lumbar disc tissue score, GM-CSF and IL-1β levels, p-JAK2/ JAK2 and p-STAT3/STAT3 levels of rats in the modelgroup were greatly increased, while the mechanical pain threshold, tail suspension test struggling time, total distance traveled, average speed, and standing/resting time in the open field test were greatly reduced. Compared with the model group, the Pfirmmann scores, tail suspension test bending time, lumbar disc tissue scores, GM-CSF and IL-1β levels, p-JAK2/JAK2 and p-STAT3/STAT3 levels of rats in the low- and high-dose ART groups were all reduced, while the mechanical pain threshold, tail suspension test struggling time, total distance traveled, average speed, and standing/resting time in the open field test were all increased, and high-dose ART had a stronger effect. Compared with the high-dose ART group, the Pfirmmann score, tail suspension test bending time, lumbar disc tissue score, GM-CSF and IL-1β levels, p-JAK2/JAK2 and p-STAT3/STAT3 of rats in the high-dose ART + DUSP19 group were increased, while the mechanical pain threshold, tail suspension test struggling time, total distance traveled, average speed, and standing/resting time in the open field test were decreased. Conclusion: ART can inhibit the inflammatory response of lumbar IVDD rats by blocking the activation of the JAK2/STAT3 signaling pathway, thereby reducing

Objective: To investigate the effect and mechanism of safflower injection in alleviating oxidative stressinduced testicular damage in diabetic male rats. Methods: Male SD rats were randomly divided into three groups: a normal group, a model group, and a treatment group. The general condition and testicular mass of the rats were compared bamong the groups, plus the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in testicular tissue. Histological structure, cell morphology, and the rate of proliferating cell nuclear antigen (PCNA)- positive cells in testicular tissue were also evaluated. Results: Compared with the normal group, the model group exhibited poorer mental state, dull and yellowish fur, increased food and water intake, more urination and defecation, significantly reduced testicular mass, and markedly decreased SOD levels and increased MDA levels in the testicular tissue. Through the observation under a light microscope, there was decreased and disordered arrangement of spermatogenic cells in the testes along with a lower rate of PCNA-positive cells. Compared with the model group, the treatment group showed improved responsiveness, less pronounced dull and yellowish fur, reduced food and water intake, and less urination, significantly increased testicular mass, elevated SOD levels, and significantly decreased MDA levels in testicular tissue. Morphological lesions in testicular tissue were alleviated, and the rate of PCNApositive cells was increased. Conclusion: Safflower injection can improve the testicular damage in male diabetic rats, and its mechanism may be related to the regulation of MDA and SOD in the oxidative stress system.

Stroke is a common neurological disorder caused by cerebrovascu lar events. Central post-stroke pain (CPSP) is a refractory complication of stroke characterized by variable onset times and diverse clinical manifestations. Its clinical management often yields poor therapeutic outcomes, significantly impairing patients' quality of life and even leading to suicidal tendencies in some cases. The pathogenesis of CPSP remains elusive. Current clinical treatments, including pharmacotherapy and adjunctive neuromodulatory therapies, have shown limited efficacy. This paper reviews recent advances in CPSP research from the perspectives of tissue, cellular, and molecular levels. It also discusses CPSP clinical treatment methods, aiming to provide new perspectives for both basic research and clinical management of CPSP.

Objective: To explore the anterior extraperitoneal anatomical targeted surgical approach for acetabular fractures and to meet the requirements for precise minimally invasive robotic-assisted orthopedic surgery. Methods: Fresh adult Chinese cadavers were used with arterial perfusion. Based on the clinical needs of internal fixation of acetabular fractures, five most common fracture sites of acetabulum were selected, including anterior column, anterior wall, acetabular roof, medial quadrilateral surface and greater ischial notch. The distribution and density of blood vessels with diameter ≧ 2.0 mm were measured in the above areas. The shortest linear distance between blood vessels and bone was categorized as follows: Grade Ⅰ (extremely hazardous, 0–5.0 mm), Grade Ⅱ (highly hazardous, 5.0–10.0 mm), or Grade Ⅲ (moderately hazardous, 10.0–20.0 mm). Venous and arterial distribution density ≥ 10, 8, 6 vessels within a 30.0 mm radius was classified as Grade A (extremely hazardous), Grade B (highly hazardous), or Grade C (moderately hazardous). According to the above measurements, the vascular protection levels for5 regions were drawn up. The extraperitoneal targeted minimally invasive surgical pathways were summarized to avoid important blood vessels. Results: Grade I vessels included the corona mortis, obturator artery and vein, femoral artery and vein, superior gluteal artery and vein, which required level Ⅰ protection. Grade Ⅱ vessels comprised iliolumbar artery and vein, internal iliac artery and vein and their branches, external iliac artery and vein, inferior gluteal artery and vein, which needed level Ⅱ protection. Grade Ⅲ vessels consisted of deep inferior epigastric artery and vein, umbilical artery and vein, testicular artery and vein, which called for level Ⅲ protection. Grade A area was located at the greater sciatic notch. Grade B area was located at the obturator area of the superior pubic ramus, the acetabular roof and the medial quadrangle. Grade C area was located on the anterior wall. Blood vessels with a diameter ≧ 5.0mm could cause rapid fatal hemorrhage after injury, including common iliac artery and vein, external iliac artery and vein, and internal iliac artery and vein. The vascular protection levels for the five regions were as follows: level ⅠA (superior gluteal artery and vein, obturator artery and vein, and coronary artery of death), level IB (Femoral artery and vein), level ⅡA (internal iliac artery and vein, external iliac artery and vein), level ⅡB (inferior gluteal artery and vein), level ⅢB (testicular artery and vein, uterine round ligament artery and vein, umbilical artery and vein). Five extraperitoneal targeted minimally invasive pathways for acetabular fractures were identified in superior pubic ramus, anterior wall (2 sites), acetabulum roof, and the greater sciatic notch area of arcuate line. Three newly discovered arteries, with 1.0–1.5 mm in diameter, which were not described in previous anatomical works and literature, were named as the pubic posterior trophic branch of the coronary artery of death, the psoas major branch and peritoneal branch of the superior gluteal artery, and the acetabular parietal trophic branch of the iliacus vessel. Conclusion: This study provides five targeted pathways for robotic-assisted orthopedic surgery to achieve precise and minimally invasive treatment of acetabular fractures, which can allow rapid access to the five targeted fracture sites of the acetabulum and reduce the iatrogenic damage to normal tissues in non-fracture areas. The three newly discovered vessels enrich anatomical understanding of acetabular vasculature and are of significant significance to avoid intraoperative vascular injury and bleeding.
