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.

OBJECTIVE To explore the mechanism of Zadi-5 pill in improving myocardial ischemia-reperfusion injury （MIRI）. METHODS The targets and pathways of potential effects of Zadi-5 pill improving MIRI were screened based on the network pharmacology. Seventy-two rats were randomly divided into model group， sham operation group， Danshen group [Compound danshen dripping pills 80 mg/（kg·d）] and Zadi-5 pill high-dose， medium-dose and low-dose groups [1.6， 0.8， 0.4 g/（kg·d）]， with 12 rats in each group. The rats in each group were given corresponding drugs intragastrically， once a day， for 14 consecutive days. After the last administration， MIRI model was established by ligating the anterior descending branch of left coronary artery in rats， while rats in the sham operation group were threaded without ligation. The contents of creatine kinase （CK）， lactate dehydrogenase （LDH）， aspartate transaminase （AST）， cardiac troponin T （CTn-T）， apoptotic rate of cardiomyocyte， phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， B-cell lymphoma-2 （Bcl-2）， Bcl-2 related X protein （Bax） and caspase-3 in myocardial tissue were detected in each group after modeling； the morphological changes of myocardial tissue were observed. RESULTS A total of 177 active ingredients and 220 targets of Zadi-5 pill were obtained， including 51 targets involved in improving myocardial ischemia； the core target of Zadi-5 pill improving MIRI was AKT1， including PI3K-Akt， endoplasmic reticulum and hypoxia-inducible factor-1. Compared with model group， the contents of CK， LDH， AST and CTn-T， the apoptotic rate of cardiomyocyte as well as the protein expressions of caspase-3 and Bax were significantly decreased in Danshen group and Zadi-5 pill high-dose group （P＜0.05 or P＜0.01）， while the protein expressions of PI3K， Akt and Bcl-2 in myocardial tissue were significantly increased （P＜0.05 or P＜0.01）， respectively； the myocardial histopathological changes were significantly improved. The above indicators were improved to varying degrees in Zadi-5 pill low-dose and medium-dose groups， too. CONCLUSIONS Zadi-5 pill may inhibit apoptosis by activating the PI3K-Akt signaling pathway， thus playing a role in improving MIRI.

Mongolian medicine is an indispensable part in developing traditional Mongolian medicine. This study is aimed to provide a basis for the formulation of clinical and Mongolian medicinal materials standards by clarifying the original plant and species collation of Mongolia medicine of "saradma". Mongolian herbal medicine, as an important part of Mongolian medicine, is needed to study the authentic Mongolian medicine, in order to exert the best therapeutic effect in the application. The Mongolian medicine of "saradma" is a kind of medicinal material for diuresis, reinforcing kidney, and eliminating edema, for which comes from the roots, stems, leaves, flowers, fruits, seeds and other parts of medicinal plant. The ancient books of Mongolian medicine are the most important reference the research of Mongolian medicine varieties. This review adopts the method of inductive comparison of ancient books in order to summarize the conclusion of Mongolian medicine of "saradma". According to the investigations, Mongolian medicine of "saradma" type is mainly Leguminosae plant, Oxytropis latibracteata, Hedysarum multijugum, Thermopsis barbata, Astragalus membranaceus, Vicia amoena, O. caerulea, Astragalus bhotanensis, Hedysarum sikkimense. Compared with modern works, it is found that the drug has a wide range of resources distribution and application. It can be used for the treatment of cold edema, hot edema, nephrogenic edema, edema, swelling and likes caused by different diseases. Based on the research of Mongolian medicine of "saradma" varieties, it was found that the most commonly used varieties in Inner Mongolia were cayan saradma, xara saradam and sira saradma all of which are all top-grade drugs that reduce swelling.
