OBJECTIVE To investigate the effects and mechanism of the Yishen paidu formula on renal fibrosis in rats with chronic renal failure (CRF) through the reactive oxygen species (ROS)/thioredoxin-interacting protein (TXNIP)/NOD-like receptor thermal protein domain associated protein 3 (NLRP3) pathway. METHODS Rats were randomly divided into control group, model group, Yishen paidu formula low-dose (Yishen paidu formula-L) group, Yishen paidu formula high-dose (Yishen paidu formula- H) group, Yishen paidu formula-H+pcDNA-NC group, and Yishen paidu formula-H+ pcDNA-TXNIP group, with 10 rats in each group. Except for control group, all other rats were fed a diet containing 0.5% adenine to establish a CRF model; the rats were then administered corresponding drugs or normal saline intragastrically or via tail vein, once daily, for 8 consecutive weeks. After the last administration, the levels of serum creatinine (Scr), blood urea nitrogen (BUN), ROS, superoxide dismutase (SOD), malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-1β were measured in each group. Pathological changes in renal tissue were observed, and the protein expression levels of Collagen Ⅲ, α-smooth muscle actin (α-SMA), transforming growth factor-β1 (TGF-β1), TXNIP and NLRP3 in renal tissue were detected. RESULTS Compared with model group, the renal histopathological damage and fibrosis of rats in Yishen paidu formula-L group and Yishen paidu formula-H group were significantly alleviated. The levels of Scr, BUN, ROS, MDA, TNF- α, IL-6 and IL-1β, and the protein expressions of Collagen Ⅲ, α-SMA, TGF-β1, TXNIP and NLRP3 were significantly decreased, while SOD levels were significantly increased (P<0.05). Moreover, the changes were more pronounced in the Yishen paidu formula-H group (P<0.05). Compared with Yishen paidu formula-H+pcDNA-NC group, above indexes of rats in Yishen paidu formula-H+pcDNA-TXNIP group were reversed significantly (P<0.05). CONCLUSIONS Yishen paidu formula can inhibit renal fibrosis in CRF rats by suppressing the ROS/TXNIP/NLRP3 pathway.

ObjectiveTo investigate the regulatory effect of overexpressed protein tyrosine phosphatase non-receptor type 2 (Ptpn2) on the inflammatory response of mouse alveolar macrophages (MH-S) induced by SiO₂. MethodsCells with overexpressed Ptpn2 were constructed and induced by SiO₂. The experimental groups were divided into four groups: the negative control group with an empty vector (NC), the overexpressed Ptpn2 group (P), the negative control group with an empty vector + SiO₂ induction (NS), and the overexpressed Ptpn2 + SiO₂ induction group (PS). Isobaric tags for relative and absolute quantification (iTRAQ) combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) were used to screen differential proteins, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) database analyses. Immunofluorescence staining was used to detect the expressions of Tumor necrosis factor (TNF) α, Gasdermin D (GSDMD), and Transforming growth factor (TGF)-β1. Western blot was used to detect the protein expression levels of PTPN2, Toll-like receptor 4 (TLR4), tumor necrosis factor-α (TNF-α), nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), and proteins related to the TGF-β1 signaling pathway in the cells of each group. ResultsiTRAQ results identified 144 differential proteins among the four groups. GO analysis showed that in biological processes (BP), these differential proteins were mainly enriched in IκB kinase/nuclear factor-κB (NF-κB) signaling, cell activation and signal transduction involved in immune responses, and regulation of receptor signaling pathways by signal transducer and activator of transcription (STAT), etc. KEGG analysis revealed that the differential proteins were mainly enriched in Toll-like receptor signaling pathway, NF-κB signaling pathway, NOD-like receptor signaling pathway, TGF-β signaling pathway, and TNF signaling pathway. The results of immunofluorescence staining showed that compared with the NC group, the expressions of TNF α, GSDMD, and TGF-β1 in the cells of the NS group increased (P < 0.05); compared to the NS group, the expression of the aforementioned proteins in the PS group decreased in cellular proteins(P < 0.05). The results of Western blot showed that compared with the NC group, the protein expression levels of PTPN2, p-NF-κB,MyD88,TLR4,NLRP3,GSDMD,Caspase-1,IL-1β, TGF-βR1, TGF-βR,p-Smad2/3 in the NS group were significantly upregulated (P < 0.05); compared with the NS group, the expression levels of the aforementioned proteins in the PS group were significantly downregulated (P < 0.05). ConclusionOverexpression of Ptpn2 can inhibit the protein expressions of TLR4-TNF-α signaling, NLRP3 signaling, and TGF-β1 signaling closely related to inflammatory response in SiO₂-mediated MH-S macrophages.

ObjectiveTo investigate the mechanisms by which Shangxia Liangji pills improve cognitive function in Alzheimer's disease (AD) mice based on the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway, aiming to provide experimental evidence for its clinical use in AD treatment. MethodsFifty APP/PS1 double-transgenic mice were randomly divided into a model group, Shangxia Liangji pills low-dose group, medium-dose group, high-dose group, and donepezil hydrochloride group, with 10 mice in each group. Additionally, 10 C57BL/6 mice of the same genetic background were assigned to the normal group. Cognitive function was assessed using the Morris water maze and novel object recognition tests. Hippocampal pathological changes were observed using transmission electron microscopy and Nissl staining. Neuroinflammation in hippocampal tissue was detected by enzyme-linked immunosorbent assay (ELISA). Protein expression levels of PI3K/Akt pathway-related proteins, postsynaptic density protein 95 (PSD95), and amyloid precursor protein (APP) in hippocampal tissue were measured by Western blot. ResultsCompared with the normal group, the model group exhibited significantly increased total swimming distance and escape latency, significantly reduced number of platform crossings (P<0.01), and a decreased recognition index (P<0.01). Marked neuronal apoptosis was observed in the hippocampal region, with a marked reduction in the number of neurons in the CA3 region (P<0.01). Levels of interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) in hippocampal tissue were significantly elevated (P<0.01). APP expression in hippocampal tissue was markedly upregulated (P<0.01), while PSD95, p-PI3K/PI3K, and p-Akt/Akt protein expression were significantly downregulated (P<0.01). Compared with the model group, the Shangxia Liangji pills high-dose group showed significantly reduced total swimming distance and escape latency, significantly increased number of platform crossings (P<0.01), and an elevated recognition index (P<0.01). Hippocampal neuronal apoptosis was alleviated, with a significant increase in the number of neurons in the CA3 region (P<0.01). Levels of IL-6, IL-1β, and TNF-α were significantly decreased (P<0.01). APP expression was downregulated (P<0.05), while PSD95, p-PI3K/PI3K, and p-Akt/Akt protein expression were significantly upregulated (P<0.01). ConclusionShangxia Liangji pills may improve cognitive function in AD mice by modulating the PI3K/Akt pathway, thereby reducing neuroinflammation and alleviating neuronal and synaptic injury.

Patients with inflammatory bowel disease (IBD) require long-term pharmacotherapy. Due to the wide variety of clinically available drugs, medication safety has become increasingly concerning. As an indispensable component of pharmaceutical formulations, drug excipients may induce various adverse reactions, including rash, allergic responses, and gastrointestinal discomfort, and may even lead to severe organic injury. However, they are often overlooked in clinical practice. Therefore, identifying and managing excipient-related adverse reactions is crucial for ensuring medication safety. To address this issue, this article systematically reviews common excipients in IBD therapeutics, the underlying mechanisms of excipient-induced adverse reactions, and corresponding management strategies, aiming to enhance clinicians' awareness of excipient-related issues, improve their ability to recognize and manage such reactions, and ultimately ensure patient safety.

BACKGROUND:Cervical rotation-traction manipulation is effective and safe in the treatment of cervical spondylotic radiculopathy,and has been widely used in clinical work.However,its effects on the biomechanics of cervical vertebra and intervertebral disc and the area of intervertebral foramen have not been systematically clarified. OBJECTIVE:Based on the finite element analysis technique,a relevant research and analysis were carried out to provide digital evidence for the mechanism of effect of cervical rotation-traction manipulation in the treatment of cervical spondylotic radiculopathy. METHODS:The CT image data of a volunteer with no neck diseases were selected as the finite element model material at its left-handed physiological limit position.The initial construction of the finite element model was completed by Mimics 19.0 software,Geomagic Studio 2013 software,Hypermash 14.0 software,and ANSYS Workbench 2020 R2 software,respectively.Based on the literature,the grid division of cervical structure and the assignment of elastic modulus and elastic coefficient were completed.Based on the previous work of the team,the mechanical effects of cervical rotation-traction manipulation were simulated on the model.Effects of cervical rotation-traction manipulation on the mechanical parameters of each vertebral body and intervertebral disc in C3-T1 segment and on the cervical lateral foramen area were analyzed. RESULTS AND CONCLUSION:(1)During cervical rotation-traction manipulation,the stress of bone structure was significantly higher than that of soft tissue such as intervertebral disc.(2)When operating the technique,the stress at the top of each cervical vertebra was higher,the stress at the bottom was lower,and the stress at the facet joint and transverse process was lower.The stress at the top of the intervertebral disc was lower,the stress at the bottom was higher,but the highest point of the intervertebral disc stress was outside the top.(3)In addition,after loading the lifting force,the projected area of the C6/C7 intervertebral foramen increased significantly compared with that before loading.(4)It is indicated that the cervical rotation-traction manipulation has the mechanical characteristics of changing the stress structure of the cervical spine itself,and can expand the C6/7 intervertebral cervical foramen area on the opposite side of the patient's cervical rotation,so as to achieve the purpose of treating cervical spondylotic radiculopathy.

Background:
The association of changes in metabolic syndrome (MetS) with cognitive function remains unclear. We explored this association using prospective and Mendelian randomization (MR) studies.
Methods:
MetS components including high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), waist circumference (WC), fasting plasma glucose (FPG), and triglycerides were measured at baseline and two follow-ups, constructing a MetS index. Immediate, delayed memory recall, and cognitive function along with its dimensions were assessed by immediate 10- word recall test (IWRT) and delayed 10-word recall test (DWRT), and mini-mental state examination (MMSE), respectively, at baseline and follow-ups. Linear mixed-effect model was used. Additionally, the genome-wide association study (GWAS) of MetS was conducted and one-sample MR was performed to assess the causality between MetS and cognitive function.
Results:
Elevated MetS index was associated with decreasing annual change rates (decrease) in DWRT and MMSE scores, and with decreases in attention, calculation and recall dimensions. HDL-C was positively associated with an increase in DWRT scores, while SBP and FPG were negatively associated. HDL-C showed a positive association, whereas WC was negatively associated with increases in MMSE scores, including attention, calculation and recall dimensions. Interaction analysis indicated that the association of MetS index on cognitive decline was predominantly observed in low family income group. The GWAS of MetS identified some genetic variants. MR results showed a non-significant causality between MetS and decrease in DWRT, IWRT, nor MMSE scores.
Conclusion
Our study indicated a significant association of MetS and its components with declines in memory and cognitive function, especially in delayed memory recall.

AIM: To investigate the relationship between Apelin and δ-like ligand 4(DLL4)expression levels and clinical stage and efficacy in patients with neovascular glaucoma(NVG).METHODS: A total of 96 NVG patients(96 eyes)who were admitted to our hospital from January 2022 to March 2024(NVG group)and 96 cataract patients(96 eyes)who underwent cataract surgery in our hospital during the same period(control group)were selected. NVG patients were divided into stage Ⅰ group(22 eyes), stage Ⅱ group(47 eyes)and stage Ⅲ group(27 eyes)according to the clinical stage; furthermore, patients were divided into ineffective group(20 eyes)and effective group(76 eyes)according to efficacy. Aqueous humor Apelin and DLL4 levels were detected by enzyme-linked immunosorbent assay. The influencing factors of the efficacy in NVG patients were analyzed by multivariate unconditional Logistic regression analysis, the evaluation efficiency of aqueous humor Apelin and DLL4 levels on the efficacy in NVG patients was analyzed by receiver operating characteristic(ROC)curve.RESULTS: Compared with the control group, aqueous humor Apelin and DLL4 levels in the NVG group were increased(all P<0.001). Aqueous humor Apelin and DLL4 levels in the stage Ⅰ, stage Ⅱ and stage Ⅲ groups increased in turn(all P<0.001). The effective rate of 96 NVG patients was 79.2%(76/96). Compared with the effective group, aqueous humor Apelin and DLL4 levels in the ineffective group increased(all P<0.001). Clinical stage III, high intraocular pressure, high Apelin and DLL4 were independent risk factors for ineffective treatment in NVG patients(all P<0.05). The area under the curve of the combined evaluation of aqueous humor Apelin and DLL4 levels in evaluating the efficacy of NVG patients was 0.874, which was greater than 0.790 and 0.786 of aqueous Apelin and DLL4 levels alone(all P<0.05).CONCLUSION: Aqueous humor Apelin and DLL4 levels in NVG patients increase, which relate to the increase of clinical stage and poor efficacy, and the combination of aqueous humor Apelin and DLL4 levels is more effective in evaluating the efficacy of NVG patients.
