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 observe the clinical efficacy of Tongtiao acupuncture-moxibustion method for long COVID-19 olfactory dysfunction. METHODS: A total of 28 patients with long COVID-19 olfactory dysfunction were selected and treated with Tongtiao acupuncture-moxibustion therapy (regulating orifices, invigorating the brain, and regulating qi and blood). Acupoints included Yintang (GV24⁺), Baihui (GV20), Fengfu (GV16), Qihai (CV6) and bilateral Yingxiang (LI20), Fengchi (GB20), Xuehai (SP10), Zusanli (ST36). Deep needling to the periosteum of the nasal bone was performed at Yintang (EX-HN3), with warming needle moxibustion applied. Each treatment lasted 40 min, administered once daily for 6 days per week, followed by a 1-day rest, over 4 consecutive weeks. T&T olfactory test scores, TCM symptom scores, serum cortisol levels, Hamilton depression scale (HAMD) scores, and Hamilton anxiety scale (HAMA) scores were compared before and after treatment. Clinical effect was evaluated based on T&T olfactory test grading. RESULTS: Compared before treatment, the T&T olfactory test scores, each TCM symptom scores, HAMD scores, and HAMA scores were decreased after treatment (P<0.01, P<0.05), while serum cortisol level was increased (P<0.01). The total effective rate was 96.4% (27/28). CONCLUSION Tongtiao acupuncture method could effectively alleviate symptoms of long COVID-19 olfactory dysfunction, increase serum cortisol level, and relieve anxiety and depressive symptoms.

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.

OBJECTIVE: To observe the effect of Huayu Tongluo moxibustion on the NOD-like receptor protein 3 (NLRP3)/cysteine-aspartic acid protease-1 (Caspase-1)/gasdermin D (GSDMD) signaling pathway in rats with vascular dementia (VD), and to explore its mechanism in improving learning and memory ability and alleviating neuronal injury in the hippocampal CA1 region. METHODS: A total of 80 SPF-grade male Wistar rats were included. Three rats were excluded based on the Morris water maze test. From the remaining rats, 12 were randomly selected as the sham operation group. The rest were used to establish VD models via modified bilateral common carotid artery ligation. Thirty-six successfully modeled rats were randomly divided into a model group, a medication group, and a moxibustion group, with 12 rats in each group. The medication group was treated with nimodipine solution (12 mg/kg) via gavage. The moxibustion group was treated with Huayu Tongluo moxibustion. The suspended moxibustion was applied at Shenting (GV24) and Dazhui (GV14), and aconite cake-separated moxibustion was applied at Baihui (GV20), with each acupoint treated for 20 min. All treatments were administered once daily for 21 consecutive days. Before and after modeling, and after intervention, the Morris water maze test was used to assess cognitive function. After intervention, the activation and morphology of microglia in the hippocampal CA1 region were observed by immunofluorescence. Ultrastructure of hippocampal CA1 neurons was examined by transmission electron microscopy. Western blot was used to detect protein expression of NLRP3, apoptosis-associated speck-like protein (ASC), Caspase-1, GSDMD, and interleukin-1β (IL-1β) in the hippocampal CA1 region. ELISA was used to detect the content of IL-6, IL-8, and tumor necrosis factor-α (TNF-α) in the hippocampal CA1 region. RESULTS: Compared with the sham operation group, the model group showed longer mean escape latency (P<0.01) and fewer platform crossings (P<0.01); the microglial processes in the hippocampal CA1 region were thickened, cytoplasm was hypertrophic, and relative fluorescence intensity of ionized calcium-binding adapter molecule 1 (IBA-1) was increased (P<0.05); the neuronal ultrastructure in the CA1 region was severely damaged, rough endoplasmic reticulum was swollen, mitochondria were deformed and swollen, some cristae were ruptured or dissolved, showing vacuolar changes; the protein expression of NLRP3, ASC, Caspase-1, GSDMD, and IL-1β, as well as levels of IL-6, IL-8, and TNF-α were significantly elevated (P<0.001). Compared with the model group, both the medication group and the moxibustion group showed shortened mean escape latency (P<0.01) and increased platform crossings (P<0.01); the microglial processes were thinner, and IBA-1 fluorescence intensity was decreased (P<0.05); the neuronal ultrastructure in the CA1 region was partially improved; the protein expression of NLRP3, ASC, Caspase-1, GSDMD, and IL-1β, and levels of IL-6, IL-8, and TNF-α were significantly reduced (P<0.001). Compared with the medication group, the moxibustion group showed shortened mean escape latency (P<0.05) and more platform crossings (P<0.05); the IBA-1 fluorescence intensity was decreased (P<0.05); the neuronal ultrastructure in the CA1 region was improved; the protein expression of NLRP3, ASC, Caspase-1, GSDMD, and IL-1β, as well as levels of IL-6, IL-8, and TNF-α, were significantly lower (P<0.001). CONCLUSION The Huayu Tongluo moxibustion could enhance learning and memory abilities in VD rats, inhibit excessive activation of microglia, and alleviate neuronal injury in the hippocampal CA1 region. Its mechanism may involve modulation of the NLRP3/Caspase-1/GSDMD signaling pathway, reduction of inflammatory responses.

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.

Objective: To determine the clinical efficacy of platelet-rich plasma (PRP) injection combined with warm acupuncture and moxibustion for treating patients with knee osteoarthritis and cold dampness obstruction syndrome. Methods: One hundred and twenty-eight patients with knee osteoarthritis and cold dampness obstruction syndrome who visited the Rehabilitation Department and Orthopedics Department of the Second Affiliated Hospital of Anhui University of Chinese Medicine from January 2023 to March 2024 and who met the inclusion and exclusion criteria were randomly divided into an experimental (n=64) and control group (n=64) using the random number table method. The experimental group was treated with PRP injection combined with warm acupuncture and moxibustion, whereas the control group was treated with normal saline injection combined with warm acupuncture and moxibustion treatment. PRP and normal saline injections were administered once every two weeks, a total of four times. Patients were treated with warm acupuncture and moxibustion once a day, six times a week, for four consecutive weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Traditional Chinese Medicine (TCM) syndrome, visual analog scale (VAS), and Lysholm scores were determined before treatment, at week 4 and week 8 of treatment, and week 16 of follow-up. Serum interleukin-6 (IL-6), matrix metalloproteinase-3 (MMP-3), tumor necrosis factor-α (TNF-α), osteoprotegerin (OPG), bone gla protein(BGP), and cartilage oligomeric matrix protein (COMP) levels were compared between the two groups before and after 8 weeks of treatment. The clinical efficacy and safety indicators between the two groups were also compared. Results: There was no statistical difference in baseline data such as gender, age, disease duration, and body mass index between the two groups of patients. Compared with before treatment, both groups showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm scores at 4, 8, and 16 weeks after treatment. After treatment, serum IL-6, MMP-3, TNF-α, and COMP levels decreased, whereas serum OPG and BGP levels increased (P<0.05). Compared with the control group, patients in the experimental group showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm score at 4, 8, and 16 weeks after treatment. Compared with the control group, patients in the experimental group showed decreased serum IL-6, MMP-3, TNF-α, and COMP levels and an increase in serum OPG and BPG levels after treatment (P<0.05). The total effective rate of the experimental group was 91.94%, higher than that of the control group (81.97%; P<0.05). Conclusion PRP injection combined with warm acupuncture and moxibustion can improve various TCM symptoms, improve knee joint function and bone metabolism, and reduce inflammation in patients with knee osteoarthritis and cold dampness obstruction syndrome.

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.

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 explore the correlations of multimodal ultrasound manifestations of Hashimoto thyroiditis(HT)with normal thyroid function and serum thyroid peroxidase antibody(TPOAb)titer.Methods Data of gray-scale ultrasound,CDFI and shear wave elastography(SWE)of 100 HT patients with normal thyroid function were retrospectively analyzed.According to gray-scale ultrasound manifestations,HT was classified into focal type(type A),nodular-like type(type B),diffuse hypoechoic type(type C)and diffuse hyperechoic type(type D).Meanwhile,based on blood flow distribution shown on CDFI,HT was classified into abundant type,increased type,normal type and sparse type.Correlations of the mean Young's modulus(Emean)of thyroid gland and CDFI classification of HT with serum TPOAb titer were analyzed.Results For all 100 cases,serum TPOAb titer was(270.31±72.63)IU/ml.There were 38 cases of type A,26 cases of type B,20 cases of type C and 16 cases of type D based on gray-scale ultrasound,and 15 cases of abundant type,9 cases of increased type,69 cases of normal type and 7 cases of sparse type based on CDFI,respectively.The Emean of thyroid in all 100 cases was(22.31±7.38)kPa.Significant differences of serum TPOAb titer and thyroid Emean were found among different gray-scale ultrasound HT types(all P＜0.05).Thyroid Emean values of all 100 patients were positively correlated with TPOAb titer(rs=0.702,P=0.037).The thyroid Emean of patients with type A,B,C and D HT were positively correlated with TPOAb titer(rs=0.752,0.823,0.853,0.497,all P＜0.05),while the CDFI types of HT were negative correlated with serum TPOAb titer(rs=-0.746,P=0.035).Conclusion Both thyroid Emean and blood flow signals in HT patients with normal thyroid function were correlated with serum TPOAb titer.
