IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide and a major cause of chronic kidney disease and kidney failure. IgAN exhibits marked heterogeneity in clinical presentation, histopathology, and pathogenic mechanisms, contributing to variable treatment responses and prognosisamong patients. Precise risk assessment and individualized intervention are therefore of critical importance. This review systematically traces the evolution of IgAN management from traditional risk stratification toward biomarker-driven precision medicine. We first review the clinical utility and limitations of established risk stratification tools, including the KDIGO guidelines, the Oxford MEST-C classification, and the International IgAN Prediction Tool. We then discuss emerging biomarkers closely linked to disease pathogenesis, including galactose-deficient IgA1 (Gd-IgA1), anti-Gd-IgA1 autoantibodies, B cell activating factor (BAFF), a proliferation-inducing ligand (APRIL), and complement components, as well as the targeted therapies they have informed. In addition, urinary biomarkers and multi-omics approaches show promise for dynamic disease monitoring and individualized risk stratification.

Objective: To explore the mechanism of Buzhong Yiqi Decoction in modulating macrophage polarization and intervening in autoimmune thyroiditis (AIT) mice. Methods: Using the random number table method, 48 SPF-grade NOD.H-2h4 mice were assigned to the normal, model, low-dose (4.10 g/kg), medium-dose (8.19 g/kg), high-dose group (16.38 g/kg) of Buzhong Yiqi Decoction, and selenium yeast tablet (0.026 mg/kg) groups, with eight mice in each group. All groups, except the normal group, were free to drink high iodine water (0.05% sodium iodide) to prepare AIT mouse models for 8 consecutive weeks. After the modeling was complete, each treatment group was orally administered with the corresponding medication, while the normal and model groups were orally administered with an equal volume of distilled water once a day for 8 consecutive weeks. High-performance liquid chromatography with an oscillometric refractive detector was used to analyze the content of Astragaloside Ⅳ in Buzhong Yiqi Decoction. Hematoxylin and eosin staining was used to observe the pathological morphology of mouse thyroid tissue. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of serum thyroid peroxidase antibody (TPO-Ab), thyroglobulin antibody (TgAb), interleukin (IL)-6, IL-10, and tumor necrosis factor-α (TNF-α). An immunofluorescence assay was used to detect the positive area percentage of M1 and M2 macrophages in mouse thyroid tissue. Flow cytometry assay was used to detect macrophage polarization in mouse spleen tissue. Real-time fluorescence quantitative PCR was used to detect the mRNA expression of nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3), nuclear factor kappa B inhibitory protein α (IκBα), and nuclear factor-κB (NF-κB) p65 in mouse spleen tissue. Western blotting was used to detect the expression of the phosphorylated IκBα (p-IκBα), phosphorylated NF-κB p65 (p-NF-κB p65), and NLRP3 protein in mouse spleen tissue. Results: The content of Astragaloside Ⅳ in Buzhong Yiqi Decoction was (7.09±0.06) g/L. Compared to the normal group, significant lymphocyte infiltration was observed in the thyroid tissue of mice in the model group. The levels of serum TPO-Ab, TgAb, IL-6, and TNF-α increased (P<0.05). The positive area percentage of M1 macrophages in thyroid tissue increased (P<0.05). The proportion of M1 macrophages and M1/M2 in spleen tissue increased (P<0.05). The relative expression levels of NF-κB p65 and NLRP3 mRNA in spleen tissue increased (P<0.05). The relative expression of p-IκBα, p-NF-κB p65, and NLRP3 proteins increased (P<0.05). Compared to the model group, the inflammation infiltration degree in the thyroid tissue of mice in each dose group of Buzhong Yiqi Decoction and selenium yeast tablet group was reduced, the serum TPO-Ab, TgAb, IL-6, TNF-α content was decreased, the spleen tissue M1/M2 was reduced, the expression of NF-κB p65 mRNA was reduced, and the relative expression levels of p-IκBα, p-NF-κB p65 protein were reduced (P<0.05). The Buzhong Yiqi Decoction high-dose and selenium yeast tablets groups showed an increase in IL-10 content, an increase in positive area percentage of M2 macrophages in thyroid tissue, an increase in M2 macrophages proportion in spleen tissue, and a decrease in NLRP3 mRNA and protein relative expression levels (P<0.05). Conclusion Buzhong Yiqi Decoction may regulate macrophage polarization by inhibiting the NF-κB/NLRP3 signaling pathway, thus improving the inflammatory damage in mice with AIT.

OBJECTIVE: To explore the effect mechanism of electroacupuncture (EA) for ameliorating diabetic peripheral neuropathy (DPN) based on the analysis of gut microbiota and metabolomics. METHODS: Thirty SPF-grade male SD rats were randomly divided into a normal group, a model group, and an EA group, with 10 rats in each one. Except in the normal group, the intraperitoneally injection with streptozotocin was used to induce diabetes mellitus model in the rest groups. In the EA group, acupuncture was delivered at bilateral "Zusanli" (ST36), "Sanyinjiao" (SP6), "Pishu" (BL20) and "Shenshu" (BL23), and electric stimulation was attached to "Zusanli" (ST36)-"Sanyinjiao" (SP6) and "Pishu" (BL20)-"Shenshu" (BL23), on the same side, with continuous wave and a frequency of 2 Hz, for 10 min in each intervention. The intervention measure of each group was delivered once every 2 days, 3 times a week, for 8 consecutive weeks. Body weight, random blood glucose (RBG), thermal withdrawal latency (TWL), and mechanical withdrawal threshold (MWT) before intervention, and in 4 and 8 weeks of intervention, separately, as well as sensory nerve conduction velocity (SCV) and motor nerve conduction velocity (MCV) of the sciatic nerve after intervention were measured. Metagenomic sequencing (MS) was used to analyze gut microbiota and screen for differential species. Liquid chromatography-mass spectrometry (LC-MS) was employed to detect the differential metabolites in plasma, and the metabolic pathway enrichment analysis was performed on the differential metabolites. Spearman correlation analysis was adopted to assess the relationship between gut microbiota and metabolomics. RESULTS: After 4 and 8 weeks of intervention, when compared with the model group, the EA group showed the increase in body weight, TWL, MWT (P<0.01), and the decrease in RBG (P<0.01). Compared with the normal group, SCV and MCV, as well as Chao1 index were dropped in the model group (P<0.01), and those were elevated in the EA group when compared with those in the model group (P<0.01). The dominant bacterial phyla of each group were Firmicutes (F) and Bacteroidota (B), the ratio of them (F/B) in the model group was lower than that of the normal group (P<0.05), and F/B in the EA group was higher when compared with that in the model group (P<0.05). In comparison with the normal group, the relative abundance increased in Prevotella, Segatella, Prevotella-hominis and Segatella-copri (P<0.05); and it decreased in Ligilactobacillus, Eubacterium, Pseudoflavonifractor, Ligilactobacillus-murinus (P<0.05) in the model group. Compared with the model group, the relevant abundance of the above mentioned gut bacteria was all ameliorated in the EA group (P<0.05, P<0.01). Among the three groups, 120 differential metabolites were identified and enriched in 28 key metabolic pathways, such as glycerophospholipid and linoleic acid, of which, glycerophospholipid was the most significantly affected pathway in EA intervention. Spearman correlation analysis showed that 6 phosphatidylcholine metabolites were significantly positively correlated with Pseudoflavonifractor and were negatively with Prevotella, Segatella, Prevotella-hominis, Segatella-copri; 5 phosphatidylethanolamine metabolites were significantly negatively correlated with Pseudoflavonifractor and positively correlated with Prevotella, Segatella, Prevotella-hominis, Segatella-copri. CONCLUSION EA may regulate metabolic pathways such as glycerophospholipid, modulate specific gut microbiota such as Pseudoflavonifractor, Prevotella, and Segatella, and the co-expressed differential metabolites like phosphatidylcholine and phosphatidylethanolamine, thereby reducing blood glucose and protecting nerve function, so as to relieve the symptoms of DPN of rats.

OBJECTIVE: To investigate the efficacy and safety of diagnostic-driven therapy for invasive fungal disease(IFD) in patients with myeloid hematologic malignancies. METHODS: A retrospective analysis was conducted on the clinical data of 91 patients with myeloid hematologic malignancies who received diagnostic-driven therapy for IFD at the Second Hospital of Anhui Medical University from January 1, 2020 to December 31, 2023. The patients were divided into two groups based on medication: 44 patients in the caspofungin group and 47 patients in the voriconazole group. The clinical efficacy and adverse reactions of the two groups were compared and analyzed. RESULTS: The overall response rates in the caspofungin and voriconazole groups were 67.4% and 60.0%, respectively. Among patients who transitioned to diagnostic-driven therapy following prophylactic or empirical treatment with triazole antifungal agents, the response rate of the caspofungin group was significantly higher than that of the voriconazole group (76.9% vs 35.3%, P <0.05). A total of 9 patients in both groups experienced adverse reactions, and no grade III or higher adverse reactions occurred. The incidence of grade I-II adverse reactions in the caspofungin group was lower than in the voriconazole group (2.3% vs 17.0%, P <0.05). CONCLUSION In patients with myeloid hematologic malignancies, caspofungin and voriconazole demonstrate comparable clinical efficacy in diagnostic-driven therapy for IFD, but caspofungin is associated with a lower incidence of adverse reactions. Caspofungin exhibits significant effectiveness when initiating diagnostic-driven therapy after prophylactic or empirical treatment with broad-spectrum triazole antifungal agents.

BACKGROUND: Previous evidence showed that ambient air pollution and cardiovascular mortality are related. However, there is a lack of evidence towards the modification effect of long-term lifestyle on the association between short-term ambient air pollution and death from cardiovascular events. METHOD: A total of 14,609 death from major adverse cardiovascular events (MACE) were identified among the China Kadoorie Biobank participants from 2013 to 2018. Ambient air pollution exposure including particulate matter 2.5 (PM_2.5), SO₂, NO₂, CO, and O₃ from the same period were obtained from space-time model reconstructions based on remote sensing data. Case-crossover design and conditional logistic regression was applied to estimate the effect of short-term exposure to air pollutants on MACE mortality. RESULTS: We found MACE mortality was significantly associated with PM_2.5 (relative percent increase 2.91% per 10 µg/m³ increase, 95% CI 1.32-4.53), NO₂ (5.37% per 10 µg/m³ increase, 95% CI 1.56-9.33), SO₂ (6.82% per 10 µg/m³ increase, 95% CI 2.99-10.80), and CO (2.24% per 0.1 mg/m³ increase, 95% CI 1.02-3.48). Stratified analyses indicated that drinking was associated with elevated risk of MACE mortality with NO₂ and SO₂ exposure; physical inactivity was associated with higher risk of death from MACE when exposed to PM_2.5; and people who had balanced diet had lower risk of MACE mortality when exposed to CO and NO₂. CONCLUSIONS The study results showed that short-term exposure to ambient PM_2.5, NO₂, SO₂, and CO would aggravate the risk of cardiovascular mortality, yet healthy lifestyle conduct might mitigate such negative impact to some extent.

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.

Objective:To explore the clinical and pathological features and survival outcomes of patients with early-onset intrahepatic cholangiocarcinoma (EOICC).Methods:This is a multicenter, retrospective cohort study. Data of 1 160 intrahepatic cholangiocarcinoma patients undergoing radical resection in 14 tertiary Grade A hospitals in China from January 2010 to November 2021 were retrospectively collected. The cohort included 632 males and 528 females, aged( M (IQR)) 61 (14) years (range: 22 to 93 years). ICC aged ≤50 years at the time of diagnosis was defined as EOICC and >50 years as late-onset intrahepatic cholangiocarcinoma (LOICC). Of these, there were 247 cases in the EOICC group and 913 cases in the LOICC. The clinical and pathological characteristics of both groups were analyzed and compared using the independent sample t-test, Mann-Whitney U test or Kaplan-Meier method. Univariate and multivariate Cox regression models for patient outcomes were constructed and forest graphed. Results:Compared with the patients in the LOICC group, patients in the EOICC group had lower carcinoembryonic antigen levels (2.5(4.0) μg/L vs. 3.1(5.2)μg/L, U=124 899, P=0.009) and CA19-9 level (63.4(524.7)U/ml vs. 77.9(611.3)U/ml, U=120 320, P=0.013), higher levels of ALT (29(35)U/L vs. 24(26)U/L, U=101 214, P=0.013), a lower score of the Eastern US Cooperative Oncology Group (0 score patients: 54.7% vs. 44.1%, χ2=12.472, P=0.014), higher TNM stage ( χ2=11.807, P=0.038), and proportion of lymph node dissection (62.3% vs. 54.1%, χ2=5.355, P=0.021). Patients in the two groups in sex, first diagnosis symptoms, intrahepatic bile duct stone history, nail protein, albumin, total bilirubin, transaminase, liver function Child-Pugh grade, T stage, stage, N stage, preoperative laparoscopic exploration proportion, tumor diameter, vascular invasion proportion, differentiation, margin, intraoperative bleeding, postoperative complications, postoperative hospital days were no statistical significance (all P>0.05). Patients in the EOICC group had better outcomes than the LOICC group (median survival time: 29.7 months vs. 25.0 months, 3-year overall survival: 45.1% vs. 37.8%, P=0.027). Conclusion:EOICC patients are better than LOICC patients in carcinoembryonic antigen, CA19-9, ALT, physical strength status and TNM stage, and the long-term prognosis is also better than LOICC patients.

Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

Objective To investigate the influence of basic condition,surgical strategy,and postoperative condition of adolescent idiopathic scoliosis(AIS)patients on the length of hospitalization.Methods A total of 145 AIS patients who underwent posterior spinal fusion and internal fixation in The First Affiliated Hospital of Naval Medical University(Second Military Medical University)from Jan.1,2014 to Dec.31,2023 with more than 2 years of follow-up were retrospectively enrolled.According to the surgical strategy,they were assigned to selective fusion group(n=50)and non-selective fusion group(n=95).AIS patients were assigned to intensive care unit(ICU)group(n=81)and non-ICU group(n=64)according to whether they were admitted to ICU.Parameters related to basic,surgical and postoperative conditions,hospital stay and postoperative hospital stay were analyzed.Multiple linear regression analysis was used to study the influencing factors of hospital stay and postoperative hospital stay.Results The number of surgical segments,surgical time,intraoperative blood loss,drainage volume on the 3rd day postoperatively,hospital stay,and postoperative hospital stay in the selective fusion group were significantly less than those in the non-selective fusion group(all P＜0.05).The patients in the ICU group were younger,had longer surgery time,had more intraoperative blood loss and blood transfusion,and had longer hospital stay and postoperative hospital stay compared with those in the non-ICU group(all P＜0.05).Correlation analysis showed that hospital stay and postoperative hospital stay were both positively correlated with ICU admission(r=0.179,0.240;both P＜0.05)and were both negatively correlated with selective fusion(r=-0.187,-0.242;both P＜0.05).Conclusion The hospital stay and postoperative hospital stay of AIS patients with non-selective fusion in posterior spinal fusion and internal fixation is longer than those of patients with selective fusion.Non-selective fusion and ICU admission may be factors contributing to the prolonged hospital stay and postoperative hospital stay in AIS patients.
