Medicinal plant underground diseases, typified by root rot, directly result in a significant reduction in both the yield and quality of traditional Chinese medicine(TCM) because of its hidden occurrence and difficulty in prevention and control. Prevention and control measures depending on chemical pesticides bring potential risks to the safety of TCM and easily cause environmental pollution. The introduction of the new version of Good Agricultural Practice for Chinese Crude Drugs(GAP) and the enhancement of pesticide residue limit standards for TCM and decoction pieces in Chinese Pharmacopoeia(2025 edition) have elevated the requirements for green and efficient disease prevention and control technologies of TCM. This paper provided a comprehensive overview of the advancements over the past two decades in the diversity of pathogens, characteristics and hazards associated with disease occurrence, the main prevention and control agents currently registered, and the prevention and control techniques for TCM root rot. In light of the environmental backdrop of global climate change and the increasing frequency of disastrous climates, coupled with the challenges encountered in root rot prevention and control amidst the new paradigm of large-scale and standardized cultivation of TCM, the paper proposed the key direction of basic research and the application strategy for new technologies that integrate "early prevention and control-soil health-digital monitoring", including precise pathogen identification and early disease diagnosis, exploration of host disease resistance mechanisms and disease-resistant breeding, field soil health and ecological regulation, monitoring of fungicide resistance and rational pesticide use, as well as the integration of digital technology and intelligent plant protection. The ultimate goal is to advance the application of green plant protection technology in TCM, thereby providing robust scientific and technological support to ensure the healthy and sustainable development of the TCM agriculture sector.

This study aims to establish the S_(180) tumor-bearing mice model, and to investigate the influence of Shenqi Erpi Granules(SQEPG) on immune function, as well as the drug's tumor-suppressive effect and mechanism. SPF grade KM mice(half male and half female) were randomly divided into 6 groups: a control group, a model group, a cyclophosphamide group(50 mg·kg~(-1)), as well as SQEPG groups in low-, medium-, and high-dose(5.25, 10.5, 21 g·kg~(-1)). The control group and the model group were given distilled water, and the other 4 groups were given the corresponding drugs by gavage. The administration continued for 10 days before the mice were sacrificed. The antitumor and immune regulation effects of SQEPG were evaluated. The effect of SQEPG on delayed type hypersensitivity reaction(DTH), carbon clearance index, and serum hemolysin antibody level was observed to reflect the effect on the immune function of tumor-bearing mice. Tumor weight was recorded to calculate the tumor suppression rate and the immune organ index. Hematoxylin-eosin(HE) staining was used to detect morphological changes in tumor tissues. Flow cytometry was employed to detect the percentage of CD4~+ and CD8~+ T-cells in the spleen tissues and the tumor tissue apoptosis levels. Immunohistochemistry was conducted to detect the KI67 protein expression level of tumor tissues. ELISA resorted to the detection of the following expression levels in tumor tissues: tumor necrosis factor-α(TNF-α), interleukin-2(IL-2), interferon-γ(IFN-γ). Western blot was performed to detect the expression levels of caspase-3, B-cell lymphoma-2(Bcl-2), Bcl-2-associated X protein(Bax), cyclin-dependent kinases 4(CDK4), G_1/S-specific cyclin D1(cyclin D1), and vascular endothelial growth factor A(VEGFA). The results showed that, compared with the model group, the SQEPG could increase the swelling of the auricle of the tumor-bearing mice; significantly increase the phagocytic index of carbon granule contour(P<0.05 or P<0.01), and the middle dose of SQEPG could significantly increase the antibody level of hemolysin(P<0.05); different doses of SQEPG significantly inhibit the growth of the tumor, and decrease the mass of the tumor tissues(P<0.05 or P<0.01); the low dose of SQEPG significantly decreased spleen index(P<0.05), low and high doses of SQEPG increased thymus index, while medium doses of SQEPG decreased thymus index. High doses of SQEPG significantly elevated the levels of CD4~+ and CD8~+ T-cells in the spleens of the homozygous mice(P<0.01 or P<0.001), and increased the apoptosis rate of the cells of the tumor tissues(P<0.05); Meanwhile, high-dose SQEPG elevated the levels of immunity factors such as IL-2, IFN-γ and TNF-α in the serum of tumor-bearing mice(P<0.01); medium-and high-dose SQEPG significantly lowered the rate of positive expression of KI67 protein in tumor tissues(P<0.01). Compared with the model group, high-dose SQEPG significantly up-regulated the expression of caspase-3 and Bax proteins in tumor tissues(P<0.05), and significantly down-regulated the expression of CDK4, cyclin D1, and VEGFA proteins(P<0.05 or P<0.01). In conclusion, SQEPG has the effect of improving immune function and inhibiting tumor growth in tumor-bearing mice. Its mechanism of tumor-suppressive effects may be related to apoptosis promotion, cell cycle progression block, and tumor cell proliferation inhibition.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Parkinson's disease(PD)is one of the most common neurodegenerative disorders.Recent evidence implicates pyroptosis as one of the pathogenic mechanisms in central nervous system disorders,although its specific mechanisms remain unclear.In this study,SH-SY5Y cells were transfected with py-roptosis-related proteins GSDME full-length(GSDME-F)or GSDME-N terminal(GSDME-N)plasmids revealed that GSDME-N significantly reduced mitochondrial membrane potential(P<0.0001).To inves-tigate the mechanism by which GSDME mediates mitochondrial dysfunction,Western blotting analysis demonstrated that transfection with GSDME-N plasmids significantly increased BAX expression and en-hanced its translocation to mitochondria in both HEK 293T and SH-SY5Y cells(P<0.05).SH-SY5Y cells treated with varying concentrations of rotenone(ROT)exhibited GSDME cleavage,elevated BAX expression(P<0.05),increased mitochondrial BAX aggregation(P<0.05),and reduced mitochondrial membrane potential(P<0.01),as confirmed by Western blotting and JC-1 staining.Concurrently,MTT assays assessing cell viability and lactate dehydrogenase(LDH)release assays indicated that ROT in-duced these processes prior to pyroptosis.Furthermore,in a ROT-induced mouse PD model,ROT trig-gered GSDME cleavage,enhanced BAX expression,caused dopaminergic neuronal damage,and induced motor deficits.In summary,this study demonstrates that GSDME-N exacerbates mitochondrial damage and increases cytotoxicity by upregulating BAX expression and facilitating its mitochondrial translocation.This study provides novel insights into the role of GSDME in PD pathogenesis and suggests potential avenues for therapeutic intervention.

Aim To investigate the role of myotubula-rin related protein 7(MTMR7)in the pathogenesis of pulmonary hypertension manifested by pulmonary vas-cular intimal thickening,right ventricular hypertrophy,progressive right heart failure and dysfunction.Meth-ods A total of 40 healthy male C57BL/6J mice and Mtmr7-transgenic(Mtmr7-Tg)mice were divided into the control group,Mtmr7-Tg group,monocrotaline(MCT)group and MCT+Mtmr7-Tg group.Pulmonary artery acceleration time(PAT)and pulmonary artery ejection time(PET)of the pulmonary artery were measured by ultrasound.When the free wall of the right ventricle was separated,the right heart hypertro-phy index(RVHI)was calculated.Pulmonary artery remodeling was observed by immunostaining.Mouse pulmonary artery smooth muscle cells(PASMCs)were cultured in hypoxic environment to induce the prolifer-ation and migration.Results MTMR7 was expressed in pulmonary vessels.Compared to the wild-type mice,Mtmr7-Tg mice showed increased PAT/PET ratio(P<0.05),reduced RVHI(P<0.01)after MCT stimu-lus.PASMCs were transfected with adenovirus encond-ing Mtmr7 gene,which inhibited proliferation and mi-gration of PASMCs.After restoring the activity of ERK1/2 by chemerin-9,the proliferation and migra-tion ability of PASMCs was elevated.Conclusions MTMR7 can counteract the growth and mobility of mouse PASMCs induced by hypoxia,thereby comba-ting pulmonary arterial hypertension via reducing ERK1/2 phosphorylation.
