BACKGROUND:Lijin manipulation can promote skeletal muscle repair and treat skeletal muscle injury.However,the formation of fibrosis and scar tissue hyperplasia are closely related to the quality of skeletal muscle repair.To study the regulatory effect of Lijin manipulation on the formation of fibrosis and scar tissue hyperplasia is helpful to explain the related mechanism of Lijin manipulation to improve the repair quality of skeletal muscle injury. OBJECTIVE:To explore the mechanism of Lijin manipulation to improve the repair quality of skeletal muscle injury in rabbits,thereby providing a scientific basis for clinical treatment. METHODS:Forty-five healthy adult Japanese large-ear white rabbits were randomly divided into blank group,model group and Lijin group,with 15 rats in each group.Gastrocnemius strike modeling was performed in both model group and Lijin group.The Lijin group began to intervene with tendon manipulation on the 3rd day after modeling,once a day,and 15 minutes at a time.Five animals in each group were killed on the 7th,14th and 21st days after modeling.The morphology and inflammatory cell count of gastrocnemius were observed by hematoxylin-eosin staining,the collagen fiber amount was observed by Masson staining,the expression of interleukin-6 and interleukin-10 in gastrocnemius was detected by ELISA.The protein and mRNA expressions of paired cassette gene 7,myogenic differentiation factor,myoblastogenin,alpha-actin,transforming growth factor beta 1,and type Ⅰ collagen were detected by western blot and RT-PCR,respectively,and the expression of type Ⅰ collagen protein was detected by immunohistochemistry. RESULTS AND CONCLUSION:Hematoxylin-eosin staining and Masson staining showed that compared with the model group,inflammatory cell infiltration and collagen fiber content decreased in the Lijin group(P<0.01),and the muscle fibers gradually healed.ELISA results showed that compared with the model group,the expression of interleukin-6 in the Lijin group continued to decrease(P<0.05),and the expression of interleukin-10 increased on the 7th day after modeling(P<0.05)and then showed a decreasing trend(P<0.05).Western blot and RT-PCR results showed that compared with the model group,the protein and mRNA expressions of paired cassette gene 7,myogenic differentiation factor,myoblastogenin in the Lijin group were significantly increased on the 14th day after modeling(P<0.05),but decreased on the 21st day(P<0.05);the protein and mRNA expressions of alpha-actin,transforming growth factor beta 1,and type Ⅰ collagen in the Lijin group were significantly decreased compared with those in the model group(P<0.05).Immunohistochemical results showed that the expression of type Ⅰ collagen in the Lijin group was significantly lower than that in the model group(P<0.05).To conclude,Lijin manipulation could improve the repair quality of skeletal muscle injury by inhibiting inflammation,promoting the proliferation and differentiation of muscle satellite cells,and reducing fibrosis.

Acupuncture-moxibustion technical specifications are a crucial component of the acupuncture-moxibustion standardization system. This study reviews the current development status of acupuncture-moxibustion technical specifications in China, and analyzes their classifications and characteristics. It is found that the scope and classification of acupuncture technical specifications remain unclear in academic circles, and the development process faces numerous difficulties and challenges. Therefore, this study proposes the need for a systematic approach to the planning and management of acupuncture technical specifications based on a clear definition of acupuncture techniques and categories. Additionally, it suggests conducting methodological research on the development of acupuncture technical specifications and promoting the rational application of the consensus method in this process.

Basket trial, as an innovative clinical trial design concept, marks the transformation of medical research from the traditional large-scale and single-disease treatment to the precise and individualized treatment. By gradually incorporating the Bayesian method during development, the trial design becomes more scientific and reasonable and increases its efficiency. The fundamental principle of the Bayesian method is the utilization of prior knowledge in conjunction with new observational data to dynamically update the posterior probability. This flexibility enhances the basket trial's capacity to effectively adapt to variations during the research process. Consequently, it enables researchers to dynamically adjust research strategies based on accumulated data and improve the predictive accuracy regarding treatment responses. In addition, the design concept of the basket trial aligns with the traditional Chinese medicine(TCM) principle of "homotherapy for heteropathy". The principle of "homotherapy for heteropathy" emphasizes that under certain conditions, different diseases may have the same treatment. Similarly, basket trials allow using a uniform trial design across multiple diseases, offering enhanced operational and significant practical value in the realm of TCM, particularly within the context of syndrome-based disease research. By introducing basket trials, the design of TCM clinical studies will be more scientific and yield higher-quality evidence. This study systematically categorized various Bayesian methods and models utilized in basket trials, evaluated their strengths and weaknesses, and identified their appropriate application contexts, so as to offer a practical guide for designing basket trials in the realm of TCM.

OBJECTIVE To analyze the correlation between styloid process related parameters and symptoms in patients with styloid process syndrome.METHODS A retrospective study was conducted on the 3D reconstruction CT results of the styloid process in 68 patients diagnosed with styloid process syndrome who visited the Department of Otolaryngology Head and Neck Surgery,the Second Affiliated Hospital of Xi'an Jiaotong University from January 2010 to December 2024.The relationship between parameters such as styloid process length,angle,distance from styloid process tip to pharynx,and specific symptoms in patients with styloid process syndrome was analyzed.RESULTS Among 68 patients with styloid process syndrome,44 had unilateral symptoms and 24 had bilateral symptoms.The length of the styloid process on the symptomatic side of patients with unilateral symptoms(3.86±0.16)cm was significantly longer than that on the asymptomatic side(2.98±0.17)cm(Z=-2.191,P=0.028);The length of the styloid process on the side with severe symptoms in patients with bilateral symptoms(3.98±0.37)cm was also significantly longer than that in patients with mild symptoms(3.37±0.15)cm(t=2.448,P=0.024).Patients with styloid process syndrome mainly present with pharyngalgia(64.71%,44/68).There were no significant differences in the length,inclination angle,anteversion angle,and distance between the styloid process tip and the pharynx among those with unilateral pharyngalgia(n=29),bilateral pharyngalgia(n=15),and non pharyngalgia(n=24)(P>0.05).However,among the 68 patients with styloid syndrome,12 had calcification of the styloid hyoid ligament,while 56 did not.The incidence of unilateral pharyngalgia was significantly higher in patients with calcification of the styloid hyoid ligament than in patients without calcification(66.7%vs.35.7%,χ2=3.909,P=0.048).CONCLUSION The severity of symptoms in patients with styloid process syndrome is related to the length of the styloid process,and those with calcification of the styloid hyoid ligament are more likely to experience pharyngalgia.

Objective To explore the protective effect of Lycium barbanun glycopeptide(LbGP)against osteogenic inhibition induced by exosomes derived from human gingival fibroblasts(HGFs)exposed to radiation.Methods Cultured HGFs with or without LbGP pretreatment were exposed to 8 Gy X-ray radiation,and the changes in cell apoptosis,senescence and α-SMA level were detected using RT-qPCR,Western blotting and β-galactosidase staining.The exosomes secreted by the treated cells were extracted,and after identification by electron microscopy,particle size analysis and Western blotting,the exosomes were added into primary cultured bone mesenchymal stem cells(BMSCs),and osteoclast activity and osteogenesis in the cell cultures were detected by Trap staining,Alizarin red staining,ALP staining,RT-qPCR and Western blotting.Results In cultured HGFs,X-ray radiation significantly increased the percentage of senescent cells,which was obviously lowered by LbGP treatment.X-ray radiation significantly reduced Bcl-2/Bax ratio and increased α-SMA expression in HGFs,and these changes were significantly suppressed by LbGP pretreatment.In rat BMSCs,incubation with the exosomes derived from HGFs with radiation exposure caused a significant increase of osteoclasts,reduced calcium nodules and lowered alkaline phosphatase expression in the cells;The opposite changes were observed in the cells treated with exosomes from LbGP-pretreated HGFs,which also significantly increased the cellular expressions of the osteogenic genes(BMP2,ALP,and RUNX2)and proteins(ALP and RUNX2)as compared with the exosomes from irradiated HGFs.Conclusion LbGP can effectively inhibit osteoclast activity and promote osteogenesis by acting on exosomes secreted by irradiated HGFs,suggesting its potential value for treatment of osteoradionecrosis of the jaw.

Keloid is a common skin disease, and the mechanism of its occurrence is not fully understood. There is evidence to show that multiple factors such as genetics, race, age, gender, hormones, infection, immunity, and oxidative stress, etc. may be related to the occurrence of keloids. Metabolic remodeling and protein acylation modification, as two important biological processes, play important roles in various skin related diseases. Based on this, this article reviews the roles of metabolic remodeling and protein acylation modification in keloids and the interrelationship between the two biological processes, and explores the application prospects of targeting the two biological processes in the prevention and treatment of keloids.
