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 analyze the pharmacodynamic activity of Bupleuri Radix processed with Trionyx sinensis blood in the treatment of Yin deficiency and study the spectrum-effect relationship of this medicine. MethodsHigh performance liquid chromatography was employed to establish the fingerprints of 15 batches of Bupleuri Radix processed with Trionyx sinensis blood， and the similarity was evaluated according to the SOP of Similarity Evaluation System of Chromatographic Fingerprint of TCM （version 2012）. A mouse model of Yin deficiency induced by thyroxine was established. The relationship between the active components and the effect on Yin deficiency was explored by grey correlation analysis and partial least squares method based on the changes in the serum levels of triiodothyronine （T3）， thyroxine （T4）， cyclic adenosine phosphate （cAMP）， and cyclic guanosine phosphate （cGMP）. The components screened out based on the spectrum-effect relationship were used for retrieval of the targets from the Traditional Chinese Medicine Systems Pharmacology and Analysis Database （TCMSP）， The Encyclopedia of Traditional Chinese Medicine （ETCM）， and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP）. Furthermore， the Online Mendelian Inheritance in Man （OMIM）， GeneCards， TTD， DisGeNET， and Drugbank were employed to establish the active component-target against Yin deficiency network of Bupleuri Radix processed with Trionyx sinensis blood. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses were carried out for the core targets. Real-time PCR was conducted to verify the predicted key pathways and mechanisms. ResultsThe fingerprints of the 15 batches of Bupleuri Radix processed with Trionyx sinensis blood showed the similarities of 0.976-0.999 with the control fingerprint. Compared with the model group， the drug administration group showed elevated levels of T3 and T4 and lowered levels of cAMP， cGMP and cAMP/cGMP. The results of grey correlation analysis showed that active components in terms of the correlations followed the trend of saikosaponin B₁ > saikosaponin B₂ > saikosaponin C > saikosaponin D > saikosaponin A. The partial least squares analysis showed that saikosaponins A， D， B₁， and B₂ had higher VIP values. Network pharmacology predicted a total of 30 common targets， which were enriched in 276 GO terns and 115 KEGG pathways. The results of Real-time PCR showed that the model group had lower mRNA levels of Caspase-9， kinase insert domain receptor （KDR）， and mammalian target of rapamycin （mTOR） and higher mRNA level of mouse double minute 2 homolog （MDM2） than the blank group and the drug administration group. ConclusionBupleuri Radix processed with Trionyx sinensis blood has therapeutic effect on Yin deficiency syndrome， which provides a new idea for studying Bupleuri Radix processed with Trionyx sinensis blood.

ObjectiveTo explore the clinical safety of Feilike Mixture （FLK） in the real world. MethodsThe safety of all children who received FLK from 29 institutions in 12 provinces between January 21，2021 and December 25，2021 was evaluated through prospective centralized surveillance and a nested case control study. ResultsA total of 3 035 juveniles were included. There were 29 research centers involved，which are distributed across 12 provinces，including one traditional Chinese medicine （TCM） hospital and 28 general hospitals. The average age among the juveniles was （4.77±3.56） years old，and the average weight was （21.81±12.97） kg. Among them，119 cases （3.92%） of juveniles had a history of allergies. Acute bronchitis was the main diagnosis for juveniles，with 1 656 cases （54.46%）. FLK was first used in 2 016 cases （66.43%），and 142 juvenile patients had special dosages，accounting for 4.68%. Among them，92 adverse drug reactions （ADRs） occurred，including 73 cases of gastrointestinal system disorders，10 cases of metabolic and nutritional disorders，eight cases of skin and subcutaneous tissue diseases，two cases of vascular and lymphatic disorders，and one case of systemic diseases and various reactions at the administration site. The manifestations of ADRs were mainly diarrhea，stool discoloration，and vomiting，and no serious ADRs occurred. The results of multi-factor analysis indicated that special dosages （the use of FLK）［odds ratio （OR） of 2.642， 95% confidence interval （CI） of 1.105-6.323］，combined administration： spleen aminopeptide （OR of 4.978， 95%CI of 1.200-20.655），and reason for combined administration： anti-infection （OR of 1.814， 95%CI of 1.071-3.075） were the risk factors for ADRs caused by FLK. Conclusion92 ADRs occurred among 3 035 juveniles using FLK. The incidence of ADRs caused by FLK was 3.03%，and the severity was mainly mild or moderate. Generally，the prognosis was favorable after symptomatic treatment such as drug withdrawal or dosage reduction，suggesting that FLK has good clinical safety.

Myocardial ischemia-reperfusion injury （MIRI） is a common cardiac pathological process， resulting from the combined effects of multiple mechanisms involving metabolic changes and mitochondrial dysfunction. Mitochondrial quality control （MQC）， as a key regulatory mechanism， may serve as an important target for the prevention and treatment of MIRI. In recent years， traditional Chinese medicine （TCM） has demonstrated unique advantages in the field of improving MIRI， with multiple targets， multiple pathways， and low toxic and side effects. It has gained widespread clinical recognition and application. Through systematically organizing and summarizing recent studies on the targeting of MQC by monomers， active fractions， herb pairs， compound formulas and related preparations of TCM to improve MIRI， this paper finds that monomers and active fractions of TCM （such as schisandrin B， isoliquiritigenin， calenduloside E， berberine， Lycium barbarum polysaccharides and so on） as well as TCM herb pairs， compound formulas， and related preparations （couplet medicinals of Fuzi-Ganjiang， Yixin formula， Shuangshen ningxin capsule， Baijin formula， Yiqi huoxue decoction and so on）， can alleviate MIRI by activating MQC to reduce oxidative stress-induced damage， promote mitochondrial biogenesis， maintain mitochondrial fission/fusion homeostasis， regulate mitochondrial autophagy， and restore mitochondrial calcium homeostasis.

Aging and cancer share overlapping characteristics, referred to as meta-hallmarks, which elucidate the convergent, antagonistic, or contradictory relationships between aging and cancer. Likewise, as a key characteristic of aging, senescent cells share some meta-hallmarks with tumor cells. These hallmarks include apoptosis resistance, metabolic alterations, secretory phenotypes, epigenetic reprogramming, and immune surveillance, all of which play pivotal roles in both tumorigenesis and senescence. Moreover, senolytic drugs, which are a class of agents selectively designed to eliminate senescent cells, have emerged as promising therapeutic agents in oncology and aging-related diseases. Since the discovery of the first senolytic drug in 2015, a diverse array of such agents has been developed. Notably, most senolytic drugs are repurposed from existing anti-tumor therapies, leveraging their shared mechanisms with senescent cells and tumor cells. Thus, this review examines the similarities between senescent cells and tumor cells, providing a better understanding of the meta-hallmarks. Besides, we categorize existing senolytic drugs based upon meta-hallmarks and elucidate the potential molecular mechanisms underlying their effects. By integrating insights from cancer and senescence research, this work aims to inspire innovative strategies for senolytic drug discovery.

Tooth autotransplantation is a restoration technology that grafts the patient's own teeth to the missing tooth area, usually by using the third molar to replace a nonnormally functioning molar for the purpose of "turning waste into treasure". Robotic surgical assistance has been widely used in the fields of breast cancer, liver cancer, and orthopedics; however, its application in the dental field, particularly in tooth autotransplantation, remains relatively rare. This paper reports a case of tooth autotransplantation with the assistance of a domestic autonomous oral surgery robot, providing a reference for the application of robotic surgery assistance in tooth autotransplantation.

Objective To explore the predictive value of lipoprotein(a) (Lp[a]) levels for major adverse cardiovascular events (MACE) in patients with acute coronary syndrome (ACS). Methods A total of 310 ACS patients who were hospitalized in Dalian Friendship Hospital and completed coronary angiography from August 2021 to October 2023 were included in this study. According to the level of Lp(a), the patients were divided into high Lp(a) group (＞300 mg/L, n=224) and low Lp(a) group (≤300 mg/L, n=86). All patients undergo outpatient follow-up after discharge, the occurrence of major MACE was recorded, and multivariate Cox regression analysis was performed to analyze the influencing factors of MACE in ACS patients. Results The age, C-reactive protein, total cholesterol, ApoB, proportion of multiple lesions and percutaneous coronary intervention (PCI), Gensini score of the high Lp(a) group were higher than those of the low Lp(a) group, while uric acid and LVEF were lower than those of the low Lp(a) group (all P<0.05). The median follow-up time for all ACS patients was 22 (17, 24) months, with a total of 61 patients (19.68%) experiencing MACE. The high Lp(a) group had a higher readmission rate and cumulative MACE incidence for angina compared to the low Lp(a) group (P=0.009, P=0.001). Single factor analysis showed that high Lp(a) level, diabetes, myocardial infarction, left main artery disease, multi vessel disease, PCI, age, Gensini score, LVEF, and homocysteine were significantly correlated with MACE (all P<0.05). After adjusting for multiple factors, the MACE risk in the high Lp(a) group was 3.42 times higher than that in the low Lp(a) group (HR=3.42, P=0.016). Conclusion Lp(a)＞300 mg/L is an independent risk factor for the development of MACE in patients with ACS, and can be used as a predictor for the development of MACE in patients with ACS.
