ObjectiveTo investigate the role of Ras-GTPase-activating protein SH3 domain-binding protein 2 (G3BP2) in regulating the activation, proliferation, and migration of hepatic stellate cells (HSCs). MethodsThe mouse HSCs (JS-1 cell line) were treated with 5 μg/L transforming growth factor-beta 1(TGF-β1) for 24 hours to establish an HSC activation and proliferation model. A G3BP2 knockdown system was constructed using siRNA interference technology. The experiment was divided into four groups: Control, TGF-β1 treatment, TGF-β1+si-NC, and TGF-β1+ G3BP2-siRNA. The expression levels of key fibrosis indicators, including type I collagen (Collagen I), α-smooth muscle actin (α-SMA), and G3BP2, were detected by Western blot and RT-qPCR. Cell proliferation activity was assessed using the CCK-8 proliferation assay kit and EdU fluorescence labeling technology. Cell migration ability was analyzed by scratch wound healing assay and Transwell migration assay. The formation level of stress granules was quantified by immunofluorescence microscopy to investigate the effects of G3BP2 on stress granule formation in activated HSCs. ResultsStimulation with TGF-β1 upregulated the expression of G3BP2 in JS-1 cells (RT-qPCR: P0.000 1; Western blot: P0.000 1), while a downward trend in its expression was observed in the G3BP2‑silenced group (RT-qPCR: P0.01; Western blot: P0.000 1). Compared with the control group, the TGF-β1 group exhibited increased protein expression levels of α-SMA and Collagen I (RT-qPCR: both P0.01; Western blot: P0.01 and P0.05, respectively), concomitant with an increased number of stress granules and enhanced cell proliferation and migration capacity (all P0.001). The experimental results demonstrated that G3BP2 knockout effectively reversed the aforementioned phenotypes, with the G3BP2-silenced group showing reduced expression of fibrotic markers (all P0.01), decreased stress granule formation (P0.01), and reduced cell proliferation and migration capacity (all P0.05), compared to the negative control group. ConclusionG3BP2 enhances the activation, proliferation, and migration of HSCs by promoting the formation of stress granules, thereby accelerating the pathological progression of liver fibrosis. This suggests that stress granules may serve as important regulators in controlling the activation, proliferation, and migration of HSCs.

Objective:
To explore the effect of YTH domain family protein 1(YTHDF1) on the activation, proliferation and migration of hepatic stellate cells(HSCs) by regulating mitochondrial fission mediated by mitochondrial fission protein 1(Fis1).
Methods:
The mouse hepatic stellate cell line JS-1 was treated with 5 ng/ml TGF-β1 for 24 h to induce its activation and proliferation, andYTHDF1-siRNA was used to construct aYTHDF1silencing model.The experiment was divided into Control group, TGF-β1 group, TGF-β1+si-NC group and TGF-β1+si-YTHDF1 group.Expression changes ofYTHDF1,Fis1and key indicators of fibrosis, type Ⅰ collagen(CollagenⅠ) and α-smooth muscle actin(α-SMA) were detected through reverse transcription quantitative polymerase chain reaction(RT-qPCR) and Western blot; CCK-8 was used to detect cell proliferation ability; Transwell migration assay and cell scratch assay were used to detect cell migration ability; immunofluorescence staining experiment was used to detect the effect ofYTHDF1onFis1-mediated mitochondrial fission; finally, JC-1 staining was used to experimentally detect the effect ofYTHDF1on mitochondrial membrane potential.
Results:
Compared with the Control group, RT-qPCR and Western blot experimental results showed that the expression ofYTHDF1andFis1increased in the TGF-β1 group(P<0.05,P<0.01;P<0.000 1), as well as the fibrosis markersCollagenⅠand the expression level of α-SMA increased(P<0.01;P<0.001,P<0.000 1); while adding CCK-8, the experimental results showed that the proliferation ability of HSCs in the TGF-β1 group was enhanced(P<0.000 1); Transwell experimental results showed that the migration ability of HSCs in the TGF-β1 group was enhanced(P<0.01); the cell scratch experiment results showed that the migration ability of HSCs in the TGF-β1 group was enhanced(P<0.000 1); the immunofluorescence experiment results showed that the TGF-β1 group Mito-Tracker Red staining andFis1co-localization signal increased(P<0.05); JC-1 staining experiment results showed that the mitochondrial membrane potential increased in the TGF-β1 group(P<0.01). Compared with the TGF-β1+si-NC group, RT-qPCR and Western blot experimental results showed that the expression ofYTHDF1andFis1in the TGF-β1+si-YTHDF1 group was reduced(P<0.01;P<0.001), and fibrosis markers the levels ofCollagenⅠandα-SMAwere reduced(P<0.01;P<0.001,P<0.01).CCK-8 experimental results showed that the proliferation ability of HSCs in the TGF-β1+si-YTHDF1 group was weakened(P<0.000 1); Transwell experiment results showed that the migration ability of HSCs in the TGF-β1+si-YTHDF1 group was weakened(P<0.001); cell scratch experiment results showed that the migration ability of HSCs in the TGF-β1+si-YTHDF1 group was weakened(P<0.000 1); immunofluorescence experiment results showed that the Mito-Tracker Red staining andFis1co-localization signal decreased in the TGF-β1+si-YTHDF1 group(P<0.01); JC-1 staining experiment results showed that mitochondrial membrane potential decreased in the TGF-β1+si-YTHDF1 group(P<0.05).
Conclusion
YTHDF1promotes the activation, proliferation and migration capabilities of HSCs by positively regulatingFis1-mediated mitochondrial fission. This suggests thatYTHDF1may be a key gene involved in regulating the activation, proliferation and migration of HSCs.

4.Progress in research on the role of calcium ion transport in dental biomineralization
Chinese Journal of Stomatology 2025;60(1):81-87
Tooth development is a complex biomineralization process formed through the interaction between epithelial tissue and mesenchymal tissue. The Ca 2+ transport channel is the intrinsic regulatory mechanism of this process, which regulates the concentration of Ca 2+ inside and outside the cell in time and space, thereby affecting the biological functions of various cells and the growth of extracellular hydroxyapatite. This article reviews the researches on the effects of Ca 2+ transport in tooth biomineralization and corresponding cell development in recent years, with the aim of providing ideas and basis for the prevention of tooth developmental defects, assisting in early clinical diagnosis, and improving treatment methods.

This paper summarizes Li Fei's academic insights and clinical experience in treating intractable facial paralysis.Li Fei posits that prolonged illness inevitably leads to deficiency and stasis,and thus,the treatment of intractable facial paralysis should first focus on identifying the etiology and syndrome differentiation,resolving stasis and unblocking stagnation,and regulating qi and blood,with particular emphasis on the relaxation of the meridian sinew system.The meridian sinew system,affiliated with the meridian and collateral,serves as the framework through which qi and blood nourish muscles,tendons,and joints,playing a crucial role in facial paralysis treatment.Guided by the theory of the meridian sinew system,Li Fei employs syndrome-based treatment,integrating the anatomy of facial expression muscles.His approach includes needle-knife therapy to release adhesions and break stasis,acupuncture to harmonize qi and blood,and intradermal needle therapy for sustained stimulation.Through these methods,the meridian sinew system is relaxed,qi and blood are regulated,and facial muscles are nourished,leading to gradual recovery from facial paralysis.

OBJECTIVE:
To investigate the therapeutic potential of octaarginine (R8)-modified essential oil from Fructus Alpiniae zerumbet (EOFAZ) lipid microspheres (EOFAZ@R8LM) for cardiovascular therapy.
METHODS:
EOFAZ@R8LM was developed by leveraging the volatilization of EOFAZ and integrating it with the oil phase of LM, followed by surface modification with cell-penetrating peptide R8 to target the site of vascular endothelial injury. The therapeutic effects of this formulation in alleviating lipopolysaccharide-induced vascular endothelial inflammation were evaluated by assessing mitochondrial membrane potential (MMP), intracellular reactive oxygen species (ROS) levels, as well as inflammatory factors interleukin-6 (IL-6) and interleukin-1β (IL-1β) levels.
RESULTS:
EOFAZ@R8LM effectively delivered EOFAZ to the site of injury and specifically targeted the mitochondria in vascular endothelial cells, thereby ameliorating mitochondrial dysfunction through regulation of MMP and reduction of intracellular ROS levels. Moreover, it attenuated the expression levels of IL-6 and IL-1β, exerting protective effects on the vascular endothelium.
CONCLUSION
Our findings highlight the significant therapeutic potential of EOFAZ@R8LM in cardiovascular therapy, providing valuable insights for developing novel dosage forms utilizing EOFAZ for effective treatment against cardiovascular diseases.

To analyze the clinical characteristics of acute diquat poisoning complicated by central nervous system injury (CNSI) and identify early risk factors, aiming to provide a theoretical basis for reducing mortality in diquat poisoning with CNSI. Clinical data from patients with acute diquat poisoning admitted to the Emergency Department of Fuyang People's Hospital Affiliated to Anhui Medical University between October 2019 and October 2024 were retrospectively analyzed. Patients were divided into CNSI and non-CNSI groups based on complications. Clinical features were compared between groups, and variables with statistical significance were subjected to binary logistic regression to identify independent risk factors for CNSI. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive value of these factors. A total of 63 eligible patients were included, with 18 deaths (28.57%) and 26 cases (41.27%) complicated by CNSI. The median time from diquat ingestion to CNSI onset was 15.5 (9.8, 31.3) hours. The CNSI group exhibited significantly higher mortality rates and required more frequent respiratory support and anti-shock therapy than the non-CNSI group (all CNSI is a fatal complication of acute diquat poisoning with high mortality. Diquat plasma concentration (≥549.95 μg/L) and APACHE Ⅱ score are independent risk factors for CNSI, and their combined application enhances predictive accuracy. These findings underscore the importance of early risk stratification and targeted interventions in high-risk populations.

OBJECTIVE:
To investigate the effects of Huayu Tongluo (transforming stasis and unblocking collaterals) moxibustion on cognitive function and insulin resistance in patients with type 2 diabetes mellitus (T2DM) and cognitive decline.
METHODS:
Ninety patients with T2DM and cognitive decline were randomly divided into a moxibustion group (n=45, 3 cases dropped out, 2 cases were eliminated) and a waiting moxibustion group (n=45, 2 cases dropped out). Both groups received routine hypoglycemic treatment for 12 weeks. The moxibustion group additionally received Huayu Tongluo moxibustion at Baihui (GV20), Shenting (GV24), and Dazhui (GV14). Pressing moxibustion was applied to Baihui (GV20) for 20 min, while suspended moxibustion was applied to Shenting (GV24) and Dazhui (GV14) for 20 min each. Treatments of moxibustion were administered every other day (three times per week) for 12 weeks. All patients were followed up for 12 weeks, during which their original hypoglycemic medication regimen was maintained. Before treatment, after 12 weeks of treatment, and at the 12-week follow-up, the scores of Montreal cognitive assessment (MoCA), mini-mental state examination (MMSE), Addenbrooke's cognitive examination Ⅲ (ACE-Ⅲ), symbol digit modalities test (SDMT), and Athens insomnia scale (AIS) and the insulin resistance index (HOMA-IR) were observed in the two groups.
RESULTS:
Compared with before treatment, the MoCA scores, MMSE scores, ACE-Ⅲ subscale scores (attention, memory, language fluency, language, visuospatial ability) and total scores, and SDMT scores were increased (P<0.01), while the AIS scores were decreased (P<0.05) in the moxibustion group after treatment and at follow-up. Compared with before treatment, the MMSE score, ACE-Ⅲ subscale scores (memory, attention) and total score after treatment, as well as the ACE-Ⅲ subscale scores (language, memory, attention) and total score, and SDMT score at follow-up were increased (P<0.05, P<0.01) in the waiting moxibustion group. Compared with before treatment, HOMA-IR was decreased in both groups after treatment and at follow-up (P<0.01). At follow-up, ACE-Ⅲ subscale scores (attention, memory), and the total score in the moxibustion group were lower than those after treatment (P<0.05, P<0.01), and the ACE-Ⅲ language subscale score, total ACE-Ⅲ score, and SDMT score in the waiting moxibustion group were higher than those after treatment (P<0.01, P<0.05). After treatment and at follow-up, compared with the waiting moxibustion group, the moxibustion group had higher MoCA scores, MMSE scores, SDMT scores, ACE-Ⅲ subscale scores (attention, memory, language fluency) and total scores (P<0.05, P<0.01), and lower HOMA-IR (P<0.05).
CONCLUSION
Huayu Tongluo moxibustion can effectively improve cognitive function in patients with T2DM and cognitive decline. This improvement may be associated with the reduction in insulin resistance.
