epsis is a systemic inflammatory response syndrome triggered by infection， and its high mortality rate is closely associated with immune imbalance， particularly the imbalance in the differentiation of helper T cell （Th） cell subsets [Th1， Th2， Th17， regulatory T cell （Treg） ] . In recent years， traditional Chinese medicine （TCM）， with its characteristics of multi-component and multi-target actions， has demonstrated unique advantages in regulating Th cell differentiation and function， as well as correcting immune imbalances in sepsis， offering new perspectives for immunotherapy of sepsis. This review summarizes relevant studies on the regulation of Th cell differentiation for sepsis treatment by TCM monomers and active ingredients （such as Astragalus membranaceus ， Scutellaria baicalensis ， Coptis chinensis ， Rheum palmatum ， Ganoderma lucidum ， Ginkgo biloba ， and Cistanche deserticola ）， the alcohol extract of Dai Baijie， and TCM formulas and preparations categorized as blood-activating and stasis-removing， purgative and laxative， warming and tonifying yang， and tonifying qi and nourishing yin. The results indicate that these TCM monomers， active ingredients， extracts， formulas， and preparations can regulate the Th1/Th2 and Th17/Treg balance， target the differentiation balance of Th cell subsets， alleviate inflammatory responses， or improve immune suppression， thereby exerting therapeutic effects on sepsis.

The intestinal flora and its metabolites are closely bound up with the metabolism and immune function of human body and at the meantime affect the metabolisms of nutrients and drugs,which play an important role in maintaining the physiological function.As the largest reservoir of microorganisms within the human body,the intestinal flora play a vital role in maintaining the health.Numerous studies have shown that the alteration of intestinal flora may not only affect the emergence of gastrointestinal diseases but also has impact on the common diseases of multiple systems,it may mediate the emergence and development of relevant diseases through gut-kid-ney axis,gut-liver axis,and gut-brain axis,and interact with the diseases.As a traditional Chinese medicine ex-ternal therapy,the traditional Chinese medicine enema therapy has remarkable advantages in treatment of various clinical diseases and shows significant effect on improvement of intestinal flora imbalance during the disease pro-gression.The effect of the traditional Chinese medicine enema therapy on improving the intestinal flora imbalance of the patients during the process of emergence and development of the common diseases is reviewed in the article.

BACKGROUND:Currently,the mandibular joint prosthesis manufactured at home and abroad needs to rely on screws to fix the condylar part of the prosthesis during the replacement process,and the retention hole is reserved to facilitate the operation during the operation.However,due to the lack of personalized jaw design,the reattachment plate may not fit the jaw,resulting in screw loosening and dislocation.Therefore,personalized condylar prosthesis replacement is of great value in the repair of the temporomandibular joint.OBJECTIVE:To design a personalized condylar prosthesis with an internal GYROID for mandibular condylar repair and reconstruction.METHODS:The GYROID structure was selected in the Rhinoceros 7 software with the single cell size of 6 mm and the wall thickness of 0.2,0.3,0.4,0.5,0.6,0.7,0.8 mm.The mechanical properties of the GYROID structure were analyzed by finite element method.3D printing of GYROID structural test specimens with different wall thickness(0.2,0.3,0.4,0.5,0.6,0.7,and 0.8 mm)was performed to test the mechanical properties of the specimens through room temperature compression experiments.A wall thickness value conforming to the range of mandibular mechanical properties was selected through finite element analysis and room temperature compression test results.An adult male mandibular CT data were used for inverse modeling to design a condylar prosthesis with an internal GYROID.Finite element analysis was used to simulate the movement of the apical staggered position and the opposite-blade jaw position after condylar prosthesis replacement.RESULTS AND CONCLUSION:(1)The results of finite element analysis and room temperature compression experiment showed that the elastic modulus of the GYROID structure increased with the increase of wall thickness.The elastic modulus of the GYROID structure with wall thickness of 0.5-0.7 mm was within the range of the elastic modulus of the mandible(1.5-4.0 GPa).Therefore,the 6 mm monocellular GYROID structural model with a wall thickness of 0.6 mm was selected for the design of the condylar prosthesis.(2)The results of finite element analysis showed that the stress distribution of mandibular model was symmetrical.The stress distribution of the two types of occlusion was roughly the same,and the stress peak was not significantly different.The stress concentrated in the neck of the condylar prosthesis,and the stress on the replacement side was slightly larger than that on the healthy side.The maximum equivalent stress of the whole internal fixation model was 269.34 MPa,and the maximum equivalent stress of the screw was 20.14 MPa.The equivalent stress and equivalent strain values of the prosthesis were greater than that of the opposite edge jaw position when the tooth tip was interlaced.The equivalent stress and equivalent strain values of the screw were smaller than that of the opposite edge jaw position when the tooth tip was interlaced.(3)The results showed that the design and retention of the personalized GYROID condylar prosthesis were good,which was consistent with the mechanical conduction of the mandible.

OBJECTIVE To explore the effect of Astragali Radix-Curcuma Zedoaria-Paridis Rhizoma(Qi-Zhu-Zao)combina-tion on inhibiting the growth and metastasis of colon cancer based on the PINK1/Parkin/EMT signaling pathway.METHODS Thirty male BALB/c mice were randomly assigned to five groups:sham operation group,model group,positive control group,high-dose Qi-Zhu-Zao group(5.85 g·kg-1),and low-dose Qi-Zhu-Zao group(2.925 g·kg-1),with six mice in each group.An orthotopic colon cancer model was established in the mice using CT26.WT cells.After 15 days of treatment,tumor and liver tissues were collected from each group.Hematoxylin and eosin(HE)staining was performed to assess tumor metastasis,and transmission electron microscopy was used to observe mitochondrial autophagy in tumor tissues.The expression of mitochondrial autophagy-related proteins PINK1,Parkin,p62,and LC3-Ⅱ/LC3-Ⅰ was analyzed using Western blot and immunohistochemistry(IHC).Additionally,the expression levels of epithelial-mesenchymal transition(EMT)-related proteins and mRNA,including E-cadherin,N-cadherin,Vimentin,and Snail,were detected using Western blot,qPCR,and IHC staining.RESULTS Compared to the model group,mice in the treatment groups exhibited significantly reduced tumor volumes and fewer metastatic foci.Additionally,liver tissues showed pathological changes,and the overall growth condition of the mice was markedly improved;the tumor tissues in the treatment groups displayed selective mitochon-drial autophagy,accompanied by the formation of autophagosomes.The treatment influenced the PINK1/Parkin pathway-mediated mi-tochondrial autophagy biological process,with PINK1,Parkin,p62,and LC3-Ⅱ/LC3-Ⅰ levels being significantly upregulated(P<0.05,P<0.01),the high-dose group exhibited a more significant impact than the low-dose group(P<0.05,P<0.01).Furthermore,the treatment groups also showed significant reductions in the protein and mRNA levels of N-cadherin,Vimentin,and Snail(P<0.05,P<0.01),along with significant increases in the protein and mRNA levels of E-cadherin(P<0.05,P<0.01),these effects were more pronounced in the high-dose group compared to the low-dose group(P<0.05,P<0.01).CONCLUSION The herbal combination of Qi-Zhu-Zao inhibits tumor growth and metastasis to a certain extent in a mouse model of orthotopic transplantation of colon cancer.The underlying mechanism may involve the restoration of mitochondrial function through the PINK1/Parkin signaling pathway and the inhibition of the epithelial-mesenchymal transition(EMT)process,thereby achieving a therapeutic effect on colon cancer.
