ObjectiveTo prepare triptolide-Chuanxiong Rhizoma extract ethanol transfersomes(TP-CX@TESs), conduct its quality evaluation, and investigate its in vitro anti-inflammatory efficacy and the underlying mechanisms. MethodsTP-CX@TESs was prepared via the ultrasonic injection method. With encapsulation efficiency and particle size as evaluation indicators, Box-Behnken design-response surface methodology(BBD-RSM) was employed to optimize the formulation process. The TP-CX@TESs prepared under the optimal process was characterized and evaluated for in vitro transdermal performance. A lipopolysaccharide(LPS)-induced RAW264.7 cell inflammation model was established. After 24 h of drug intervention, the levels of inflammatory factors such as nitric oxide(NO), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) in the cell supernatant were detected. Western blot was used to determine the protein expression levels of Janus kinase 2(JAK2), signal transducer and activator of transcription 3(STAT3), and α7 nicotinic acetylcholine receptor(α7nAChR), and real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) was applied to measure the mRNA expression levels of JAK2, STAT3, the encoding gene of α7nAChR(CHRNA7), and nuclear transcription factor-κB(NF-κB). ResultsResults of BBD-RSM showed that the optimal formulation for preparing TP-CX@TESs was as follows:egg yolk lecithin content of 2.3%, ethanol volume fraction of 30%, and ratio of polysorbate-80 to egg yolk lecithin of 2∶5. Microscopic characterization revealed that TP-CX@TESs exhibited a spherical-like structure with a particle size of (105.60±3.85) nm, a polydispersity index of 0.19±0.03, and a Zeta potential of (-15.89±0.98) mV. The encapsulation efficiencies of triptolide, ferulic acid, and ligustilide were (76.88±4.40)%, (78.84±4.40)%, and (65.88±0.06)%, respectively. Both in vitro release and transdermal penetration of triptolide, ferulic acid, and ligustilide in TP-CX@TESs all followed the first-order kinetic model, showing a certain sustained-release property. Experimental results in RAW264.7 cells indicated that TP-CX@TESs significantly inhibited the release of NO, TNF-α, and IL-6(P<0.01), remarkably upregulated the protein expression levels of STAT3 and α7nAChR(P<0.01), increased the mRNA expression level of CHRNA7, and significantly downregulated the mRNA expression level of NF-κB(P<0.05, P<0.01). ConclusionThe optimized formulation process of TP-CX@TESs is simple and feasible, along with favorable in vitro release property, good transdermal permeability, and excellent in vitro anti-inflammatory activity, the mechanism is related to the inhibition of NF-κB.

ObjectiveTo investigate the role of runt-related transcription factor 3 (RUNX3) in transforming growth factor-β1 (TGF-β1)-induced activation of mouse primary pulmonary fibroblasts (PFs), and its effects on fibroblast activation protein (FAP) expression, cell proliferation, and collagen synthesis. MethodsPFs were isolated from C57BL/6 mice and cultured. A RUNX3 knockdown model was established using small interfering RNA (siRNA). Cells were assigned to the control group (Control), TGF-β1-treated group (TGF-β1), negative control group (TGF-β1+siRNA-NC), and RUNX3-silenced group (TGF-β1+si-RUNX3). In addition, a RUNX3 overexpression rescue experiment was performed based on TGF-β1 stimulation. Protein and mRNA levels of RUNX3, FAP, and typeⅠcollagen (COL1A1) were measured by Western blot and reverse transcription quantitative real-time PCR (RT-qPCR). Cell proliferation was assessed using CCK-8 and EdU assays. Co-expression of COL1A1 and FAP was examined by double immunofluorescence staining. ResultsCompared with the Control group, RUNX3, FAP, and COL1A1 expression levels were upregulated in PFs in the TGF-β1 group (P<0.01). The CCK-8 assay showed that the absorbance value was reduced in the RUNX3 knockdown group compared with the negative control group (P<0.01). Consistently, the EdU assay demonstrated a lower proportion of EdU-positive cells in the RUNX3 knockdown group than in the negative control group (P<0.01). Immunofluorescence double staining revealed decreased fluorescence intensities of COL1A1 and FAP in the RUNX3 knockdown group relative to the negative control. Under RUNX3 overexpression conditions, these fluorescence signals exhibited a partial rebound (P<0.01). ConclusionRUNX3 in TGF-β1-induced PFs may promote cell proliferation and collagen synthesis by positively regulating FAP expression. Targeting the RUNX3/FAP axis may represent a potential therapeutic strategy for pulmonary fibrosis.

ObjectiveTo explore the protective effect and underlying mechanism of Gegen Qinliantang on cognitive function in db/db mice with diabetic cognitive impairment (DCI). MethodsThirty-two 8-week-old male db/db mice were randomly assigned to the model group, dapagliflozin group (1.0 mg·kg-1·d-1), low-dose Gegen Qinliantang group (6.24 g·kg-1·d-1), and high-dose Gegen Qinliantang group (24.96 g·kg-1·d-1). Eight db/m mice served as the normal group. All mice were administered the corresponding treatment once daily by gavage for 10 consecutive weeks. Body weight and fasting blood glucose (FBG) were dynamically monitored. The Morris water maze test was used to evaluate cognitive function. Hematoxylin-eosin (HE) staining and Nissl staining were used to observe pathological changes in the hippocampus. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in hippocampal tissue. Immunofluorescence double staining was used to detect the co-expression of M1 microglial marker CD16/32 and ionized calcium-binding adapter molecule 1 (IBA1) in the hippocampus. Western blot analysis was performed to detect the protein expression of postsynaptic density protein 95 (PSD-95), synapsin (SYN), nuclear factor-κB p65 (NF-κB p65), and phosphorylated NF-κB p65 (p-NF-κB p65) in the hippocampus. ResultsCompared with the normal group, the model group showed significantly increased body weight and FBG levels (P<0.01), significantly prolonged escape latency and reduced platform crossings in the Morris water maze test (P<0.01), disordered arrangement of hippocampal neurons, nuclear pyknosis, increased neuronal necrosis, reduced Nissl bodies, decreased expression of synaptic proteins PSD-95 and SYN (P<0.01), increased CD16/32+ /IBA1+ positive rate, elevated levels of TNF-α and IL-1β, and an increased p-NF-κB p65/NF-κB p65 ratio (P<0.01). Compared with the model group, the dapagliflozin group exhibited significantly reduced FBG levels at weeks 5 and 10 (P<0.05, P<0.01) and increased body weight. The high-dose Gegen Qinliantang group showed significantly reduced FBG at week 10 (P<0.05). Escape latency was significantly reduced on days 3 and 5 of the water maze test in the dapagliflozin group and on day 5 in the high-dose Gegen Qinliantang group (P<0.05). Platform crossings were significantly increased in both the dapagliflozin group and the high-dose Gegen Qinliantang group (P<0.05). Hippocampal pathological damage was alleviated to varying degrees in the dapagliflozin group and the low- and high-dose Gegen Qinliantang groups, with significantly increased expression of PSD-95 and SYN (P<0.01). Further studies revealed that both low- and high-dose Gegen Qinliantang reduced hippocampal IL-1β levels and the CD16/32+/IBA1+ positive rate of microglia, while the high-dose group also significantly reduced hippocampal TNF-α levels and the p-NF-κB p65/NF-κB p65 (P<0.05, P<0.01). ConclusionGegen Qinliantang can improve hyperglycemia, cognitive dysfunction, and synaptic damage in DCI, inhibit M1 polarization of microglia and neuroinflammation, and its mechanism may be related to the inhibition of NF-κB activation.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C0), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug-drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Hearing loss is the most prevalent disabling disease. Cochlear implantation(CI) serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system(Favorable, Marginal, Poor). The consensus focuses on common hereditary non-syndromic hearing loss(such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1) and syndromic hereditary hearing loss(such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome), which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.
