Cremastrae Pseudobulbus Pleiones Pseudobulbus is a Chinese medicinal material used for clearing heat， detoxicifying， resolving phlegm， and dissipating nodules. It is derived from Cremastra appendiculata， Pleione bulbocodioides， or Pleione yunnanensis， as recorded in the 2025 edition of the Pharmacopoeia of the People′s Republic of China， with the former known as Maocigu and the latter two known as Bingqiuzi. Current antitumor studies mainly focus on polysaccharides， water-extracted alcohol-precipitated fractions， and purified extracts of C. appendiculata. Structurally characterized glucomannans suppress breast and liver tumor xenografts and exhibit immunomodulatory effects. The water-extracted alcohol-precipitated fractions inhibit tumor angiogenesis in hepatoma-bearing mice. A purified C. appendiculata extract standardized to five phenanthrene and bibenzyl constituents induces mitochondrial apoptosis in hepatocellular carcinoma cells. Reported pharmacological effects involve cell-cycle regulation， apoptosis， epithelial-mesenchymal transition， angiogenesis， autophagy， and the tumor immune microenvironment， with phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）， Wnt/β-catenin， and Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3） signaling pathways being the major mechanism links. Quality evaluation of Cremastrae Pseudobulbus Pleiones Pseudobulbus has progressed from single-marker assays to an integrated approach involving botanical authentication， chromatographic fingerprinting， multicomponent analysis， and evaluation of associations between blood-absorbed constituents and antitumor effects. Militarine and dactylorhin A can be used for botanical identification and batch evaluation， and in vivo exposure data from related orchids are concentrated on militarine. Quantitative associations between these constituents and antitumor effects remain to be established. Clinical evidence mainly focuses on formula-based applications and expert experience. Comparative antitumor data in hepatoma models are available for the commercial specifications of Maocigu and Bingqiuzi， whereas parallel evaluations of pharmacological effects， safety windows， and drug interactions among the three official botanical origins remain insufficient. The major limitations are the incomplete standardization of botanical origins and preparations and the lack of quantitative links among quality markers， systemic exposure， antitumor effects， and toxicity endpoints， which constrain reproducible pharmacological evaluation and clinical translation of Cremastrae Pseudobulbus/Pleiones Pseudobulbus.

Objective:To discuss the effect of concentrated growth factor(CGF)on the performance of bone marrow mesenchymal stem cells(BMSCs)sheets,and to clarify the role of CGF-containing composite cell sheets(CS)in the bone defect repairment.Methods:In in vitro experiments,the BMSCs were isolated and cultured from two 3-week-old SD rats;Alizarin Red S and Oil Red O staining were used to identify the osteogenic and adipogenic capabilities of BMSCs;CGF liquid extracts(CGFe)was prepared from three 3-week-old SD rats.The cells were divided into control group,traditional CS(BMSC-CS)group,and CGF-containing composite CS(CGF/BMSC-CS)group.The morphology of the CS in two groups was observed by HE staining.Alizarin Red and alkaline phosphatase(ALP)staining were used to detect the osteogenic differentiation of the CS in various groups;cell scratch assay was used to detect the migration abilities of the cells in various groups;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the mRNA expression levels of ALP,collagen are type 1(COL-1),Runt-related transcription factor 2(RUNX2),and osteocalcin(OCN)in the cells in various groups.In in vivo experiments,15 SD rats were randomly divided into control group,BMSC-CS group,and CGF/BMSC-CS group;micro computed tomography(Micro-CT)was used to detect the bone formation parameters in skull defects of the rats in various groups;HE staining and Masson staining were used to observe the morphology of skull defect tissue of the rats in various groups.Results:The third-generation BMSCs were spindle-shaped,closely arranged,and grew in a vortex cluster.The Alizarin red staining results showed obvious calcium nodules,and the Oil red O staining showed red lipid droplets,confirming the cells'ability to undergo osteogenic and adipogenic differentiation.The CS were white and semi-transparent,with slightly curled edges.The peeled CS were irregularly curled and wrinkled.Compared with BMSC-CS group,the CS in CGF/BMSC-CS group were whiter,less transparent,significantly increased in thickness and extensibility,less prone to breakage,and had a certain degree of stickiness and plasticity.The HE staining results showed that compared with BMSC-CS group,the number of the cells of CS in CGF/BMSC-CS group was increased,with denser arrangement and more abundant extracellular matrix(ECM),which wrapped and connected the cells to form an integral sheet-like structure.The Alizarin red and ALP staining results showed that compared with control group,the ALP activity and mineralization uplift value of CS in BMSC-CS group were significantly increased(P<0.05);compared with control group and BMSC-CS group,the number of osteoblasts and red mineralized nodules in the CS in CGF/BMSC-CS group was significantly increased,with obvious deepening of the staining,increased positive area,and the ALP activity and mineralization uplift value were significantly increased(P<0.05).Compared with BMSC-CS group,the ALP activity and mineralization uplif value of the CS in CGF/DMSC-CS group were increased(P<0.05).The cell scratch assay results showed that after 24 of culture,compared with control group,the migration rates of the cells in BMSC-CS group and CGF/BMSC-CS group were significantly increased(P<0.05).Compared with BMSC-CS group,the migration rate of the cells in CGF/BMSC-CS group was significantly increased(P<0.01).After 48 h of culture,compared with control group,the migration rate of the cells in CGF/BMSC-CS group was significantly increased(P<0.05).The RT-qPCR results showed that compared with control group,the expression levels of COL-1 and OCN mRNA in the cells in BMSC-CS group were significantly increased(P<0.01),and the expression levels of ALP,COL-1,OCN,and RUNX2 mRNA in the cells in CGF/BMSC-CS group were significantly increased(P<0.01).Compared with BMSC-CS group,the expression levels of ALP,COL-1,and OCN mRNA in the cells in CGF/BMSC-CS group were significantly increased(P<0.01).The Micro-CT detection results showed that in control group,the boundary of the rat skull defect area was clear,with almost no new bone formation.In BMSC-CS group,a small amount of new bone formed only at the edge of the bone defect in skull of the rats,with a significant gap in the central area of the defect.In CGF/BMSC-CS group,new bone formed along the edge of the bone defect towards the central area in skull of the rats,repairing most of the bone defect.Compared with control group,the bone volume(BV)and trabecular number(Tb.N)of the rats in BMSC-CS group were significantly increased(P<0.05);the bone volume(BV),bone volume fraction[BV/tissue volume(TV)],trabecular thickness(Tb.Th),and trabecular number(Tb.N)in skull of the rats in CGF/BMSC-CS group,were significantly increased(P<0.05).Compared with BMSC-CS group,the BV,BV/TV,Tb.Th,and Tb.N in skull of the rats in CGF/BMSC-CS group were significantly increased(P<0.01).The HE and Masson staining observation showed that in control group,almost no new bone formed in the skull defect tissue of the rats,with only a large amount of collagen fibers connecting the two sides of the bone ends.In BMSC-CS group,a small amount of new bone formed only at the edge of the bone defect in skull tissue of the rats,with the central area of the defect containing dense collagen fibers connected to the newly formed bone at the defect edge.In CGF/BMSC-CS group,new bone tissue could be seen at the edge of the bone defect,and bone islands formed in the central area of the defect,surrounded by osteocytes and a large amount of collagen fibers.The Masson staining observation results showed that the cytoplasm and osteoid were red,and the collagen was blue.In CGF/BMSC-CS group,newly formed osteoid was observed in skull defect tissue of the rats,with the highest amount of new bone formation.Conclusion:CGF can promote the osteogenic differentiation and increase the richness of ECM in BMSCs sheets.CGF-containing composite CS can efficiently repair skull defects of the rats and serve as an ideal and safe material for promoting the bone regeneration.

Objective:To discuss the therapeutic effect of resveratrol on the temporomandibular joint osteoarthritis(TMJOA),and to clarify the related mechanism.Methods:Forty-five SD rats were randomly divided into control group,model group,and resveratrol group,and there were 15 rats in each group.The rats in model group and resveratrol group were intra-articularly injected with 50 μL of 20 g·L-1 monosodium iodoacetate(MIA)to set TMJOA rat models,while the rats in control group were injected with an equal volume of normal saline.Three weeks after modeling,the rats in resveratrol group received an injection of 80 μL resveratrol solution,once a week for three weeks,while the rats in control and model groups were injected with an equal volume of normal saline.Micro-computed tomography(Micro-CT)system was used to detect the condyle structure and the bone volume fraction(BV/TV),trabecular thickness(Tb.Th),trabecular spacing(Tb.Sp),and trabecular number(Tb.N)of the rats in various groups were calculated;HE staining and toluidine blue staining were used to observe the pathomorphology of temporomandibular joint(TMJ)tissue of the rats in various groups;immunohistochemistry was used to detect the expression levels of SRY-related HMG box(SOX)-9,matrix metalloproteinase(MMP)-13,silent information regulator(Sirt)1,phosphatidylinositol 3-kinase(PI3K),phosphorylated protein kinase B(p-Akt),and phosphorylated mammalian target of rapamycin(p-mTOR)in TMJ tissue of the rats in various groups;real-time quantitative PCR(RT-qPCR)method was used to detect the expression levels of SOX-9,MMP-13,Sirt1,PI3K,mTOR,and Akt mRNA in TMJ tissue of the rats in various groups.Results:Three weeks after modeling,condylar bone was destructed,the surface was roughness,and continuity interruption were observed,indicating TMJOA model of the rats was established successfully.The Micro-CT system results showed that the condylar surface of the rats in control group was smooth and regularly shaped,with continuous bone texture;the rats in model group had significant condylar destruction,disrupted continuity,surface roughness,and varying degrees of bone defects;the rats in resveratrol group showed alleviated condylar lesions and improved appearance.Compared with control group,the BV/TV and Tb.Th of the rats in model group were significantly decreased(P<0.05),and Tb.Sp was significantly increased(P<0.05);compared with model group,the BV/TV and Tb.Th of the rats in resveratrol group were significantly increased(P<0.05),and the Tb.Sp was significantly decreased(P<0.05).The HE staining results showed clear layers and orderly chondrocyte arrangement in condyle of the rats in control group;the rats in model group showed rough uneven surface,obvious defects,and typical TMJOA features;the rats in resveratrol group showed slightly rough surface with generally clear layers and orderly arranged cells.The toluidine blue staining results showed distinct blue-purple staining of chondrocytes in hypertrophic layer of the rats in control group;pale staining or even loss of staining in some areas of the rats in model group;and distinct and relatively uniform staining in hypertrophic layer of the rats in resveratrol group.The immunohistochemistry results showed that compared with control group,the expression levels of MMP-13,PI3K,p-Akt,and p-mTOR proteins in TMJ tissue of the rats in model group were significantly increased(P<0.05),while the expression levels of SOX-9 and Sirt1 proteins in TMJ tissue of the rats were significantly decreased(P<0.05);compared with model group,the expression levels of SOX-9 and Sirt1 proteins in TMJ tissue of the rats in resveratrol group were significantly increased(P<0.05),whereas the expression levels of MMP-13,PI3K,p-Akt,and p-mTOR proteins were significantly decreased(P<0.05).The RT-qPCR results showed that compared with control group,the expression levels of MMP-13,PI3K,Akt,and mTOR mRNA in TMJ tissue of the rats in model group were significantly increased(P<0.05),while the expression levels of SOX-9 and Sirt1 mRNA were significantly decreased(P<0.05);compared with model group,the expression levels of SOX-9 and Sirt1 mRNA in TMJ tissue of the rats in resveratrol group were significantly increased(P<0.05),whereas the expression levels of MMP-13,PI3K,Akt,and mTOR mRNA were significantly decreased(P<0.05).Conclusion:Resveratrol has therapeutic effect on TMJOA,and its mechanism may be related to the activation of Sirt1 and inhibition of the PI3K-Akt-mTOR signaling pathway.

CD4 +T cells play an important role in regulating adaptive immune responses to various inflammatory responses. Parental T cell populations can differentiate in response to different cytokines into at least four subpopulations: Th1, Th2, Th17, and Treg cells. These differentiated T cells participate in various immune responses and have different roles and functions in oral cancer and precancerous diseases. The Th1/Th2 balance, the Th17/Treg balance and the occurrence and development of oral cancer and precancerous diseases are related to immune imbalances. Reversing these T cell imbalances and strengthening the patient’s autoimmune function may prevent or even reverse the progression of oral and precancerous diseases. This paper reviews the research advances on the CD4 +T cell balance in oral cancer and precancerous lesions.
