ObjectiveTo investigate the effects of rhizosphere organic acids secreted by the roots of Salvia miltiorrhiza on continuous cropping obstacles. MethodsThe mixed solution of organic acids in the rhizosphere of S. miltiorrhiza in continuous cropping and rotation cropping was added to the hairy roots subcultured for 21 days, and samples were collected on days 0, 2, 4, 6, 8, and 10. The changes of biomass, effective components, primary metabolites, secondary metabolites, antioxidant enzymes, and hormones in hairy roots of S. miltiorrhiza were observed and determined. ResultsCompared with the rotation cropping group and the blank control group, the simulation of organic acid secretion from the roots of S. miltiorrhiza had a significant inhibitory effect on the growth of hairy roots and decreased the content of effective components as well as total sugar and total protein in primary metabolites. Compared with the blank control group, the rotation cropping group and the continuous cropping group showed total sugar and total protein content decreases of 33.9% and 5.1%, respectively. On the other hand, the secretion of organic acids from S. miltiorrhiza roots significantly promoted the accumulation of total phenolic acids and total tanshinone, which showed increases of 14.6% and 1.6%, respectively, in continuous cropping group and rotation cropping group compared with the blank control group. ConclusionThe organic acid environment under continuous cropping significantly inhibited the growth of hairy roots and the accumulation of primary metabolites, while promoting the synthesis and accumulation of secondary metabolites of S. miltiorrhiza.

Myelodysplastic syndrome (MDS), a myeloid tumor derived from the malignant clones of hematopoietic stem cells, has an annually increasing incidence. The contemporary research direction has shifted to analyzing the synergistic effect of immune surveillance collapse and abnormal bone marrow microenvironment in the pathological process of MDS. Against this backdrop, the immune checkpoint molecule TIM3 has emerged as a key target because of its persistently high expression on the surface of important immune cells such as T and NK cells. The abnormal activation of the TIM3 pathway is the mechanism by which solid tumors and hematological malignancies achieve immune escape and is a key hub in the formation of immune exhaustion phenotypes. This work integrates the original discoveries of our team with the latest international progress, systematically demonstrating the bidirectional regulatory network of TIM3 between the malignant clone proliferation of MDS and the immunosuppressive microenvironment. Integrating the evidence from emerging clinical trials allows us to consider the clinical significance of TIM3-targeted blocking for MDS, providing a transformative path to overcome the resistance of traditional treatments and marking a new chapter in the active immune reconstitution of MDS treatment.

Objective To explore the effects of Jinghou Zengzhi Granules(JHZZG),on ovarian GDF9 secretion and granulosa cells(GCs)apoptosis in controlled ovarian hyperstimulation(COH)rats through p38MAPK/CK2/IκBα/NF-κB pathway.Methods A model of COH rats was prepared and 18 rats were randomly divided into 3 groups,including natural ovulation group(NO group),COH group,and COH+JHZZG group.The expression of p38MAPK,CK2,IκBα,NF-κB,GDF9 mRNA and protein were detected by qRT-PCR and Western blot,and the apoptosis rate of ovarian GCs by TUNEL.Results Compared with the NO group,the expression of p38MAPK and NF-κB in the ovarian tissue of rats in the COH group increased,while the expression of CK2,IκBα and GDF9 decreased,and the apoptosis rate of ovarian GCs increased(all P<0.01).Compared with the COH group,the expression of p38MAPK and NF-κB in the ovarian tissue of rats in the COH+JHZZG group decreased,while the expression of CK2,IκBα and GDF9 increased(all P<0.01),and the apoptosis rate of ovarian GCs decreased(P<0.05).Conclusion Jinghou Zengzhi Granules could promote the secretion of ovarian GDF9 and inhibit the apoptosis of ovarian GCs of COH rats through p38MAPK/CK2/IκBα/NF-κB signaling pathway,which thereby improve the quality of COH oocytes.
8.Review of methods for establishing limbal stem cell deficiency in animal model
Chinese Journal of Experimental Ophthalmology 2024;42(2):202-208
Limbal stem cell deficiency (LSCD) is a common ocular surface disease.Severe LSCD can cause irreversible vision loss and the only effective treatment for severe LSCD is keratoplasty, which is limited by the number of donors.Exploring new effective treatments in lieu of keratoplasty remains a hot topic in current research.Since new treatments need to be critically evaluated in reliable animal models that reflect the pathological mechanisms of human LSCD, the establishment of an appropriate animal model is crucial in any experiment.Up to now, the main modeling methods for LSCD are mechanical method, thermal injury, chemical method, chemical method combined with surgery, and gene knock-down.Mechanical method is mature, reliable and widely used, but it can cause serious mechanical damage.Rotate burr tool could be the best mechanical method because of uniform damage and the small trauma, but it requires accumulation of experience.Cornea suffered from thermal injury performs stable, but the operation is complicated and uncontrollable.Chemical method is quick and simple, and the etiology is highly consistent with clinical cases, but the depth and extent of injury are uncontrollable.The chemical method combined with surgery could ensure the smoothness and flattening of the corneal surface, but the thickness of the central cornea and the limbus may be inconsistent, which affects neovascularization.The gene knockdown method is not widely used because of its complicated operations.Although there are different types of methods, the quality of modeling in different studies is not consistent.Therefore, selecting a reliable and efficient animal model of LSCD is not convenient for researchers.This review discussed current methods to establish LSCD model, including their advantages and disadvantages, therefore to provide inspiration for future model improvement.
