Based on the view that wind pathogen runs through the entire course of the occurrence and development of nephrotic syndrome, it is proposed that the core pathogenesis of refractory nephrotic syndrome (RNS) in children involves imbalance of the lung, spleen, and kidney, invasion of wind pathogen, and stagnation of turbidity and stasis, and that directing the turbid downward with wind medicinals is the key therapeutic strategy. In clinical practice, according to the distinct pathogenic characteristics of three patterns, including defensive qi insecurity of the lung, yang deficiency with loss of regulation, and binding of turbidity and stasis, three corresponding methods are applied, which are diffusing the lung to consolidate defensive qi, elevating yang to supplement the spleen and kidney, and activating blood to unblock turbidity and stasis. For the pattern of defensive qi insecurity of the lung, wind medicinals are used to penetrate and disperse external pathogens, such as fangfeng (Radix Saposhnikoviae) and mahuang (Herba Ephedrae) for diffusing the lung, dispersing wind, and consolidating defensive qi. For yang deficiency with loss of regulation pattern, wind medicinals are employed to elevate yang and assist transformation, such as shengma (Rhizoma Cimicifugae) and gegen (Radix Puerariae Lobatae) for raising clear yang, warming and activating the spleen and kidney. For binding of turbidity and stasis pattern, wind medicinals with scurrying and collateral‑unblocking properties are used, such as jixueteng (Caulis Spatholobi), luoshiteng (Caulis Trachelospermi), and chuanshanlong (Rhizoma Dioscoreae Nipponicae) for dispelling wind, activating blood, resolving stasis, and directing turbidity downward. In all these methods, the core principle is to use wind medicinals to regulate qi movement, open and unblock the sweat pores, and separately eliminate turbid pathogens, thereby providing a theoretical and practical basis for the traditional Chinese medicine diagnosis and treatment of RNS in children.

Autosomal dominant tubulointerstitial kidney disease (ADTKD) is a rare autosomal dominant hereditary disorder characterized by hyperuricemia, gout, impaired urinary concentration, and progressive renal failure. It is primarily caused by mutations in uromodulin (UMOD) gene. This study reports a family with ADTKD in which whole-exome sequencing and Sanger sequencing identified a missense mutation in the UMOD gene, c.761A>C (p.H254P), present in both the proband and affected relatives. According to American College of Medical Genetics and Genomics (ACMG) guidelines, this variant is classified as likely pathogenic. The mutation results in an amino acid substitution that may impair UMOD protein folding and intracellular trafficking. UMOD gene mutations are associated with ADTKD, and genetic testing plays a vital role in the early diagnosis and treatment of this condition, highlighting its importance in the diagnosis of rare kidney diseases.

Paclitaxel (PTX), a valuable natural product derived from Taxus species, exhibits remarkable anti-cancer properties. It penetrates nanopores in microtubule walls, interacting with tubulin on the lumen surface and disrupting microtubule dynamics, thereby inducing cytotoxic effects in cancer cells. PTX and its derivatives have gained approval for treating various diseases due to their low toxicity, high efficiency, and broad-spectrum application. The widespread success and expanding applications of PTX have led to increased demand, raising concerns about accessibility. Consequently, researchers globally have focused on developing alternative production methods and applying nanocarriers in PTX delivery systems to enhance bioavailability. This review examines the challenges and advancements in PTX sourcing, production, physicochemical properties, anti-cancer mechanisms, clinical applications, trials, and chemo-immunotherapy. It aims to provide a comprehensive reference for the rational development and effective utilization of PTX.

Periodontitis and rheumatoid arthritis (RA) are chronic inflammatory diseases that share similar inflammatory mechanisms and characteristics. Programmed cell death (PCD) has recently garnered attention for its crucial role in regulating inflammation and maintaining tissue homeostasis, as well as for its potential to link these two diseases. The various forms of PCD--including apoptosis, pyroptosis, and necroptosis--are closely controlled by signaling pathways such as Toll-like receptor 4 (TLR4) /NF-κB and MAPK. These pathways determine cell fate and influence inflammatory responses, tissue destruction, and repair, and they both play important roles in the pathogenesis of RA and periodontitis. In periodontitis, periodontal pathogens such as Porphyromonas gingivalis (P. gingivalis) and its virulence factors, including lipopolysaccharide (LPS), induce pyroptosis and necroptosis in immune cells such as macrophages via the TLR4/NF-κB pathway, which leads to an excessive release of pro-inflammatory cytokines such as interleukin (IL)-1β and tumor necrosis factor (TNF)-α. Concurrently, these pathogens inhibit the normal apoptotic process of immune cells, such as neutrophils, prolonging their survival, exacerbating immune imbalance, and aggravating periodontal tissue destruction. Similarly, in RA synovial tissue, fibroblast-like synoviocytes (FLS) acquire apoptosis resistance through signaling pathways such as the Bcl-2 family, JAK/STAT, and NF-κB, allowing for the consistent proliferation and secretion of matrix metalloproteinases and pro-inflammatory cytokines. Meanwhile, the continuous activation of pyroptotic pathways in neutrophils and macrophages results in the sustained release of IL-1β, further exacerbating synovial inflammation and bone destruction. Notably, dysregulated PCD fosters inter-organ crosstalk through shared inflammatory mediators and metabolic networks. Damage-associated molecular patterns (DAMPs) and cytokines that originate from periodontal lesions can spread systemically, influencing cell death processes in synovial and immune cells, thereby aggravating joint inflammation and bone erosion. By contrast, systemic inflammation in RA can upregulate osteoclastic activity or interfere with the normal apoptosis of periodontal cells via TNF-α and IL-6, ultimately intensifying periodontal immune imbalance. This review highlights the pivotal bridging role of PCD in the pathogenesis of both periodontitis and RA, providing a reference for therapeutic strategies that target cell death pathways to manage and potentially mitigate these diseases.

Objective:To analyze inpatients preferences for an unaccompanied ward and its influencing factors, for references for the implementation of unaccompanied ward management.Methods:Based on a convergent mixed research design, a convenience sampling method was used to select inpatients who visited a tertiary hospital from June to August 2024 as the survey subjects. A questionnaire survey was conducted on their willingness to choose the unaccompanied ward (provided by medical nursing staff). Meanwhile, using purposive sampling method, 10 inpatients and 11 accompanying family members were selected for semi-structured interviews about unaccompanied ward prference, and the interview topics were summarized and extracted. The results of quantitative and qualitative were compared and integrated.Results:The quantitative research results showed that among the 805 inpatients included, 125 patients (13.03%) chose medical caregivers, 382 patients (39.83%) chose their spouses, and 272 patients (28.36%) chose their children; 411 patients (24.54%) did not choose medical caregivers due to financial burden; 509 patients (63.23%) believed that the cost of an unaccompanied ward should be less than 120 yuan/day. The qualitative research results showed that the interview data formed three themes, including the driving factors of caregiving form selection intention, the emotional tendency of caregiving form selection intention, and the assessment of the benefits and drawbacks of caregiving form selection intention. The mixed research results showed that the majority of inpatients choose their spouse or children accompany them, and their willingness to choose medical caregivers is mainly influenced by service costs and family labor. However, its did not affect patients who are young or have difficulty caring for them; Influenced by traditional Chinese culture, patients tended to choose relatives to accompany them; The main reasons why patients did not choose unaccompanied wards were the economic burden and the mismatch between medical nursing staff services and their expectations.Conclusions:Inpatients tended to choose family members to accompany them. Their willingness to choose unaccompanied ward was influenced by economic burden, family labor, patient age, caregiving difficulty, and filial piety culture.

Objective:To investigate the mechanism through which ginsenoside Re enhances lipid metabolism and mitochondrial function in H9C2 cardiomyocytes induced by high glucose and high fat, specifically by modulating AMP-activated protein kinase(AMPK)and specificity protein 1(Sp1).Methods:The H9C2 cardiomyocyte model was cultured in a high-glucose and high-lipid(HGHL)environment.Six groups were established: a control group(CON group), a model group(HGHL group), a ginsenoside Re 60 μmol/L group(Re 60 μmol/L), a model+ ginsenoside Re 20 μmol/L group(HGHL+ Re 20 μmol/L), a model+ ginsenoside Re 40 μmol/L group(HGHL+ Re 40 μmol/L), and a model+ ginsenoside Re 60 μmol/L group(HGHL+ Re 60 μmol/L).Cell morphology was assessed using hematoxylin and eosin(HE)staining, while intracellular oil and triglyceride content were evaluated using oil red O staining.Reactive oxygen species(ROS)levels were measured with a fluorescence kit, apoptosis was assessed using TUNEL staining, and the expressions of phosphorylated AMPK, Sp1, nuclear respiratory factor 1(Nrf1), and peroxisome proliferator-activated receptor gamma coactivator 1 alpha(PGC1α)were analyzed via Western blotting.Results:Compared to the control group, the model group exhibited significant increases in cell hypertrophy, ROS levels, apoptosis, and intracellular TG.Conversely, the expressions of pAMPK, Nrf1, and PGC1α were significantly decreased, while the expression of Sp1 was significantly increased( P<0.05).Compared to the model group, treatment with Ginsenoside Re at concentrations of 20 μmol/L, 40 μmol/L, and 60 μmol/L significantly improved cell hypertrophy, reduced ROS levels, alleviated apoptosis, and decreased intracellular TG levels.Additionally, the expressions of pAMPK, Nrf1, and PGC1α were significantly increased, while Sp1 expression was significantly decreased in a dose-dependent manner( P<0.05). Conclusions:Ginsenoside Re enhances lipid metabolism, mitigates mitochondrial oxidative stress, and reduces apoptosis in H9C2 cardiomyocytes induced by high glucose and high lipid conditions.This effect is associated with the regulation of AMPK and Sp1 proteins, leading to increased expressions of pAMPK, Nrf1, and PGC-1α, and decreased expression of Sp1.
