BACKGROUND:Degenerative scoliosis is defined as a condition that occurs in adulthood with a coronal cobb angle of the spine>10° accompanied by sagittal deformity and rotational subluxation,which often produces symptoms of spinal cord and nerve compression,such as lumbar pain,lower limb pain,numbness,weakness,and neurogenic claudication.The finite element method is a mechanical analysis technique for computer modelling,which can be used for spinal mechanics research by building digital models that can realistically restore the human spine model and design modifications. OBJECTIVE:To review the application of finite element method in the etiology and treatment of degenerative scoliosis. METHODS:The literature databases CNKI,PubMed,and Web of Science were searched for articles on the application of finite element method in degenerative scoliosis published before October 2023.Search terms were"finite element analysis,biomechanics,stress analysis,degenerative scoliosis,adult spinal deformity"in Chinese and English.Fifty-four papers were finally included. RESULTS AND CONCLUSION:(1)The biomechanical findings from the degenerative scoliosis model constructed using the finite element method were identical to those from the in vivo experimental studies,which proves that the finite element method has a high practical value in degenerative scoliosis.(2)The study of the etiology and treatment of degenerative scoliosis by the finite element method is conducive to the prevention of the occurrence of the scoliosis,slowing down the progress of the scoliosis,the development of a more appropriate treatment plan,the reduction of complications,and the promotion of the patients'surgical operation.(3)The finite element method has gradually evolved from a single bony structure to the inclusion of soft tissues such as muscle ligaments,and the small sample content is increasingly unable to meet the research needs.(4)The finite element method has much room for exploration in degenerative scoliosis.

ObjectiveTo evaluate the efficacy of Shuanghua drink in treating primary dysmenorrhea in the rat model and explore its mechanism of action. MethodsAn oxytocin-induced writhing mouse model was established to evaluate the analgesic effect of Shuanghua drink. Forty-eight non-pregnant female institute of cancer research (ICR) mice were randomly divided into six groups, including a blank group, a model group, an ibuprofen group (85.00 mg·kg-1), a low-dose group of Shuanghua drink (7.14 mL·kg-1), a medium-dose group of Shuanghua drink (14.28 mL·kg-1), and a high-dose group of Shuanghua drink (28.57 mL·kg-1). Each group consisted of eight mice. All treatment groups received daily intragastric administration at corresponding doses for 10 consecutive days. One hour after the final administration, 2 U of oxytocin was intraperitoneally injected per mouse. The writhing latency and number of writhing within 20 minutes were recorded. A primary dysmenorrhea rat model was established by using estradiol benzoate and oxytocin to evaluate the inhibitory effect of Shuanghua drink on the contraction of uterine smooth muscle. Forty-eight non-pregnant female Sprague-Dawley (SD) rats were divided into six groups, including a blank group, a model group, an ibuprofen group (51.00 mg·kg-1), a low-dose group of Shuanghua drink (4.28 mL·kg-1), a medium-dose group of Shuanghua drink (8.57 mL·kg-1), and a high-dose group of Shuanghua drink (17.10 mL·kg-1). Each group consisted of eight rats. Rats received subcutaneous injections of estradiol benzoate for 10 consecutive days to enhance uterine sensitivity. On the eleventh day, oxytocin (2 U/rat) was intraperitoneally administered to induce abnormal uterine contractions for establishing the primary dysmenorrhea model. All treatment groups received daily intragastric administration from the second day of modeling for 10 days. The effects of Shuanghua drink were evaluated by using parameters including uterine motility and the variation rate of uterine motility. The mechanism of action was investigated in rats with primary dysmenorrhea. The content of prostaglandin F2α (PGF2α), prostaglandin E2 (PGE2), thromboxane B2 (TXB2), prostacyclin metabolite (6-keto-PGF1α), and β-endorphin (β-EP) in uterine tissue of rats was detected by using enzyme-linked immunosorbent assay (ELISA). The changes in the content of nitric oxide (NO) and inducible nitric oxide synthase (iNOS) were analyzed via colorimetric assay. Western blot was performed to determine the content of phosphorylated inhibitor of kappa B kinase beta (p-IKKβ)/IKKβ, phosphorylated inhibitor of kappa B alpha (p-IκBα), IκBα, phosphorylated p65 (p-p65), p65, and cyclooxygenase-2 (COX-2) proteins in uterine tissue of rats. ResultsIn the oxytocin-induced writhing mouse model, the model group exhibited significantly shortened writhing latency and increased writhing frequency compared to the control group (P<0.01). Both the ibuprofen group and the high-dose group of Shuanghua drink displayed prolonged writhing latency (P<0.05), while the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink exhibited reduced writhing frequency (P<0.01). In the primary dysmenorrhea rat model, the uterine motility and its variation rate in the model group were significantly higher than those in the blank group (P<0.01). These parameters were markedly suppressed by ibuprofen and Shuanghua drink at all tested doses (P<0.01). For the mechanism of action, the model group showed significantly increased PGF2α/PGE2, TXB2/6-keto-PGF1α, NO, and iNOS in uterine tissue (P<0.05, P<0.01) and significantly decreased β-EP (P<0.01). These parameters were significantly attenuated in the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink. The PGF2α/PGE2 (P<0.01), TXB2/6-keto-PGF1α (P<0.01), NO (medium-dose group P<0.05), and iNOS (P<0.01) were reduced, and the β-EP (medium-dose group P<0.05) was up-regulated. Compared to the model group, the ibuprofen group and medium-dose group of Shuanghua drink showed significantly increased content of β-EP in the serum of rats (P<0.05). Compared to the blank group, the model group showed significantly elevated expressions of COX-2, p-IKKβ/IKKβ, p-IκBα/IκBα, and p-p65/p65 proteins (P<0.01) and significantly reduced anti-inflammatory protein IκBα (P<0.05). Compared to the model group, the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink showed significantly reduced expressions of COX-2 (P<0.01), p-IKKβ/IKKβ (P<0.01), p-IκBα/IκBα (P<0.05, P<0.01), and p-p65/p65(P<0.01) and up-regulated expression of IκBα protein (P<0.05, P<0.01). ConclusionShuanghua drink effectively alleviates primary dysmenorrhea through analgesia and suppression of abnormal contractions of uterine smooth muscle. Its mechanism may be mediated by reduced levels of PGF2α/PGE2, TXB2/6-keto-PGF1α, iNOS, and NO, elevated β-EP level, and inhibited COX-2/NF-κB signaling pathway.

ObjectiveTo study the mechanism of compound Xishu granules (CXG) in inhibiting the proliferation of hepatocellular carcinoma cells by regulating ferroptosis. MethodsThe transplanted tumor model of human Huh7 was established with nude mice and the successfully modeled mice were randomized into model, Fufang Banmao (0.21 g·kg-1), low-dose (1.87 g·kg-1) CXG, medium-dose (3.74 g·kg-1) CXG, and high-dose (7.49 g·kg-1) CXG groups. Mice were administrated with drinking water or CXG for 28 days, and the body weight and tumor volume were measured every 4 days. Hematoxylin-eosin staining was employed to observe the histopathological changes of tumors. The cell-counting kit-8 (CCK-8) was used to examine the survival rate of Huh7 cells treated with different concentrations (0, 31.25, 62.5, 125, 250, 500, 1 000 mg·L-1) of CXG for 24 h and 48 h. CA-AM, DCFH-DA, and C11-BODIPY581/591 fluorescent probes were used to determine the intracellular levels of ferrous ion (Fe2+), reactive oxygen species (ROS), and lipid peroxide (LPO), respectively. The colorimetric method was employed to measure the levels of glutathione (GSH) and superoxide dismutase (SOD). Western blot was employed to determine the protein levels of glutathione peroxidase 4 (GPX4), transferrin receptor 1 (TFR1), and ferritin heavy chain 1 (FTH1), respectively. ResultsIn the animal experiment, compared with the model group, the drug treatment groups showed reductions in the tumor volume from day 12 (P<0.01). After treatment, the Fufang Banmao and low-, medium-, and high-dose CXG groups had lower tumor volume, relative tumor volume, and tumor weight than the model group (P<0.05), with tumor inhibition rates of 48.99%, 79.93%, 91.38%, and 97.36%, respectively. Moreover, the CXG groups had lower tumor volume and relative tumor volume (P<0.05 in all the three dose groups) and lower tumor weight (P<0.05 in medium-dose and high-dose groups) than the Fufang Banmao group. Compared with the model group, the drug treatment groups showed reduced number of tumor cells, necrotic foci with karyopyknosis, nuclear fragmentation, and nucleolysis, and the high-dose CXG group showed an increase in the proportion of interstitial fibroblasts. In the cell experiment, compared with the blank group, CXG reduced the survival rate of Huh7 cells in a dose-dependent manner after incubation for 24 h and 48 h (P<0.05). Compared with the blank group, the RSL3 group and the low-, medium-, and high-dose CXG groups showed a decrease in the relative fluorescence intensity of CA-AM and increases in the fluorescence intensity of DCFH-DA and fluorescence ratio of C11-BODIPY581/591, which indicated elevations in the levels of Fe2+ (P<0.01), ROS (P<0.05), and LPO (P<0.01), respectively. Compared with the blank group, the RSL3 and low-, medium-, and high-dose CXG groups showed lowered levels of GSH and SOD (P<0.05). In addition, the RSL3 group and the medium- and high-dose CXG groups showed down-regulated expression of GPX4 and FTH1 (P<0.05), and the low- and high-dose CXG groups presented up-regulated expression of TFR1 (P<0.05). ConclusionCXG suppresses the proliferation of hepatocellular carcinoma cells by inducing ferroptosis via downregulating the GSH-GPX4 signaling axis and increasing intracellular Fe2+and LPO levels.

BACKGROUND:Various clinical strategies for the treatment of tendinopathy have good short-term effects but poor long-term effects,and some studies have proven that mitochondria are closely related to the occurrence and development of tendinopathy.However,the relationship between mitochondria and tendinopathy and mitochondria-targeting therapeutic strategies for tendinopathy have not been summarized so far,which is not good for specialists and scholars in related fields to understand the recent research situation.OBJECTIVE:To review the existing clinical or preclinical original studies,in order to summarize the relationship between mitochondrial dysfunction and tendinopathy and the mitochondria-targeting methods for the treatment of tendinopathy,and to provide certain prospects for the evaluation and management of mitochondria in tendinopathy in the future.METHODS:The relevant literatures in PubMed,Web of Science,CNKI,WanFang and VIP databases were searched.The search time was from January 2009 to March 2024,and the search terms were"tendinopathy,tendon injuries,tendon,tendons,mitochondria,mitochondria dysfunction,mitochondria disease"both in English and Chinese.According to the exclusion and inclusion criteria,62 articles were finally included for review and analysis.RESULTS AND CONCLUSION:(1)In clinical tendinopathy patients or tendinopathy models,mitochondrial dysfunction is common,mainly represented by excessive production of reactive oxygen species,decreased activity of superoxide dismutase,ridge clutter and decreased number of mitochondria,which indicates that mitochondrial dysfunction will occur due to tendon injury,thus further worsening tendinopathy and forming a vicious cycle.(2)When the tendon has not been injured or tendinopathy has not yet occurred,the mitochondrial function will be affected by various internal and external factors,resulting in tendinopathy.This indicates that the normal tendon will be damaged,lesioned or even ruptured due to the abnormal function of the mitochondria.(3)Mechanical tensile stress,advanced glycosylation end products,aging and other internal and external factors are the main causes of mitochondrial dysfunction,and these factors will damage and weaken the biological activity and mechanical properties of normal tendons through molecular mechanisms such as apoptosis,inflammation and respiratory chain damage,and thereby induce tendinopathy.(4)According to molecular mechanisms,mitochondria-targeting therapies mainly include mitochondrial transfer/transplantation,transplantation,targeted antioxidants,etc.(5)This review mainly aims at clinical patients with tendinopathy or animal models with similar modeling methods,providing a reliable idea for clinical exploration of the pathogenesis of tendinopathy and targeted therapies for tendinopathy.However,the disadvantage is that the included studies are mainly animal experiments,and there is a lack of more clinical trials for verification.

Objective:To investigate the methods and skills required for the safe and swift removal of primary or secondary sacral tumors located between the second (inclusive) and fourth sacral vertebrae.Methods:The clinical images, pathology reports, surgical procedures, operation durations, intraoperative bleeding volumes, and postoperative functional follow-up data of 26 patients undergoing sacral tumor resection at the First Affiliated Hospital of Zhengzhou University and Xinjiang Production and Construction Corps Hospital between May 2020 and February 2025 were retrospectively examined. Additionally, the safety measures for sacral tumor resection and techniques for expedited specimen removal were evaluated.Results:According to magnetic resonance imaging (MRI) findings, all 26 patients presented with sacral tumors located between the second (inclusive) and fourth sacral vertebrae. Specifically, 9 patients were diagnosed with primary sacral tumors, pathologically confirmed as chordomas, while 17 patients had secondary sacral tumors. Among the secondary tumor cases, 12 were attributed to recurrent rectal cancer invading the sacrum, and 5 were due to malignant teratomas invading the sacrum. The 26 patients underwent a treatment strategy that began with managing the relationship between the internal iliac artery, vein branches, and the tumor, followed by the resection of the sacrum. During surgery, the bilateral sciatic foramina were accurately positioned, and the presacral fascia was dissected subsequent to the fracture of the sacrum. Among the 26 patients, 9 underwent sacral tumor resection directly through the posterior sacral approach. The average operation time for these patients was (71.1±4.9) minutes, with average blood loss of (186.7±72.8) milliliters. On the other hand, 17 patients underwent sacral tumor resection by transitioning from the supine position to the prone knife position through a combined abdominal and sacral approach. The average operation time for this group was (213.5±19.3) minutes, with average blood loss of (480.0±93.0) milliliters, significantly longer than that of the posterior sacral approach. The follow-up period ranged from 1 to 48 months, with a median of 20 months, ending on March 31, 2025. During this time, 26 patients achieved autonomous defecation with the aid of medication. None of the patients reported any functional movement disorders or pain in their lower limbs. It was observed that two out of the 26 patients developed distant metastasis, while the remaining 24 patients survived without any tumors.Conclusion:By pretreated the relationship between the internal iliac vessels and sacral tumors prior to resecting sacral tumors, utilizing the approach of initially fracturing the sacrum followed by rupturing the presacral fascia, the tumor can be entirely eliminated, resulting in a brief surgical procedure, reduced intraoperative bleeding, and minimal postoperative complications.
