Renal involvement, occurring in approximately -1% to 5% of patients with sarcoidosis, is characterized mainly by granulomatous interstitial nephritis. Angiotensin-converting enzyme (ACE) reflects the presence of granuloma; accordingly, serum ACE (sACE) and tubular injury markers are measured in renal sarcoidosis (RS). However, these markers possess low diagnostic accuracy; therefore, we hypothesized that urinary ACE (uACE) could reflect granuloma in the kidneys and be a disease-specific marker for RS. In this single-center retrospective study, the sACE and uACE levels were measured and the creatinine-corrected ratio of uACE and sACE (u/s ACE ratio) was calculated. Additionally, patients with sarcoidosis without renal insufficiency (RI), sarcoidosis with RI, and tubulointerstitial nephritis (TIN) without a sarcoidosis etiology were included as controls. This study included 18, 18, 14, and 10 patients in the RS, sarcoidosis without RI, sarcoidosis with RI, and TIN without sarcoidosis etiology groups, respectively. uACE and u/s ACE ratio in the RS group were higher than those in the control groups. In the RS group, u/s ACE ratio was positively correlated with the degree of tubulointerstitial injury (r = 0.69, P = 0.0045); the cutoff value of u/s ACE ratio for diffuse tubulointerstitial injury was 0.39%, with a sensitivity and specificity of 100.0% each. Furthermore, obvious positive correlations were observed among u/s ACE ratio, inflammatory cell infiltrates (r = 0.53, P = 0.044), and interstitial fibrosis (r = 0.56, P = 0.029) in the RS group. u/s ACE ratio and sACE could be useful biomarkers for diagnosing RS in sarcoidosis and TIN, respectively. A simple uACE assay could help diagnose and assess disease severity in patients with RS.

Combined Effects of Puerarin and Adipose-Derived Stem Cells on Alveolar Bone Preservation and Inflammation Control in Periodontitis Through p38MAPK Modulation.

Liver fibrosis, a wound-healing response to chronic injury, can progress to cirrhosis and hepatocellular carcinoma. We investigated Tripartite motif-containing protein 26 (TRIM26) in liver fibrosis and its mechanisms. TRIM26 knockout (Trim26⁻/⁻) mice were generated to study Trim26's role in liver fibrosis. Histological analyses, qPCR, and western blotting were conducted to examine fibrosis markers and macrophage activation. In vitro studies examined macrophage polarization and hepatic stellate cells (HSCs) activation. Co-immunoprecipitation and ubiquitination assays were performed to explore the interaction between TRIM26 and enhancer of zeste homolog 2 (EZH2). TRIM26 expression was significantly downregulated in human cirrhotic tissues and fibrotic mouse livers. In Trim26⁻/⁻ mice, CCl₄- and BDL-induced fibrosis models exhibited exacerbated collagen deposition, elevated α-smooth muscle actin (α-SMA), and type I collagen (Collagen I) expression, whereas AAV-mediated Trim26 restoration markedly ameliorated these pathological features. Transcriptomic and cellular analyses indicated that Trim26 deficiency increased the pro-inflammatory cytokines, activated NF-κB and STAT1 signaling pathways, enhanced M1 macrophage polarization, and increased inflammatory cell infiltration. In vitro experiments confirmed that conditioned medium from Trim26-deficient macrophages significantly promoted α-SMA and collagen expression in HSCs. Mechanistically, TRIM26 interacts with EZH2, inhibiting TRAF6-mediated K48-linked ubiquitination and degradation to maintain EZH2 stability. EZH2, in turn, suppresses STAT1 transcriptional activity by catalyzing H3K27me3 modification on the STAT1 gene chromatin. EZH2 degradation leads to STAT1 upregulation, exacerbating M1 macrophage polarization. Trim26 attenuates liver fibrosis by stabilizing EZH2 and regulating macrophage polarization, which reduces HSC activation.

Effective preventive measures for radiotherapy and chemotherapy-induced esophagitis are currently lacking. This study aims to investigate the local impact of chemotherapeutic agents on normal esophageal tissue and assess the cytoprotective effects of amifostine against chemotherapy-induced esophageal injury. Twenty-four New Zealand white rabbits were randomly assigned to the control group, which only received saline; the cisplatin (DDP) group, which received 0.25 mg/ml of the chemotherapeutic drug (DDP); and the combined treatment group, which received pre-treatment with 0.8 mg/ml amifostine followed by 0.25 mg/ml DDP. Each group consisted of eight rabbits. A custom-made balloon device for targeted esophageal drug delivery was inserted into the esophagus, followed by the infusion of DDP and/or amifostine into the created space. After six days, rabbits were euthanized, and esophageal specimens were examined for mucosal damage. Macroscopically, compared with the control group, the DDP group exhibited significant thickening, edema, mucosal ulceration, and congestion in the infused esophageal region. Conversely, the combined treatment group showed mild thickening and a smooth or mildly congested mucosal surface. Microscopically, the DDP group displayed extensive mucosal detachment, edema, dilated submucosal blood vessels, and substantial infiltration of inflammatory cells. The combined treatment group exhibited partial mucosal detachment and moderate inflammatory cell infiltration in the submucosal and muscular layers, with few inflammatory cells in the muscle layer. This study provided evidence that damage caused by the local infusion of DDP might be reduced by pre-treatment of the cytoprotective agent amifostine.

The objective of this study was to investigate the protective effect of electroacupuncture (EA) preconditioning on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. The changes in inflammatory factors and total protein content in bronchoalveolar lavage fluid (BALF) were quantified using enzyme-linked immunosorbent assay (ELISA) and bicinchoninic acid assay (BCA). Hematoxylin and eosin (H&E) staining was employed to assess the extent of lung injury, while Ly-6G immunohistochemistry was used to examine the infiltration of inflammatory cells. Western blot analysis was employed to detect the expression of TRPV4 and proteins associated with the mitogen-activated protein kinase (MAPK) signaling pathway. In comparison with the sham-operated group, the model group demonstrated an elevated production of inflammatory factors in the BALF, augmented total protein content, elevated lung injury score, increased number of Ly-6G-positive cells, upregulation of TRPV4 expression in the lung, and enhanced p38 phosphorylation. The aforementioned pathological changes were significantly improved by EA preconditioning. Furthermore, the protective effect of EA preconditioning on ALI mice was verified by the use of GSK1016790A, an agonist of TRPV4, which demonstrated that this effect is exerted through the TRPV4-mediated p38 MAPK signaling pathway.

In recent decades, Cold Atmospheric Plasma (CAP) has become increasingly popular in healthcare for managing diseases, especially skin cancer. This study aimed to assess the preclinical safety of an indigenously developed dielectric barrier discharge-CAP device and its cytotoxic efficacy against melanoma cells while adhering to OECD 402 guidelines for acute dermal toxicity study. The safety evaluation includes ex vivo studies on mouse peritoneal exudates and in vivo acute dermal toxicity tests on Wistar rats. The ex vivo study of mice peritoneal cells treated for up to 120 seconds, showed a survival rate of over 90% up to 90 seconds of CAP treatment for applied voltage 18.6 kV at 20 kHz with no significant difference with control. In the acute dermal toxicity tests, CAP exposure for up to 30 seconds caused minimal inflammatory cell infiltration and no significant Dermal Inflammation Scoring (DIS) (<1). The efficacy study against G361 human melanoma cells showed reduced cell viability by ~50% (MTT assay) upon 30 seconds of CAP treatment for applied voltage 24 kV at 20 kHz through ROS-mediated apoptosis, confirmed by a 3-fold increase in intracellular reactive oxygen species levels and nuclear fragmentation (4',6-diamidino-2-phenylindole staining). Annexin V/PI (propium iodide) staining further revealed ~30% apoptosis after 24 hours of incubation. These findings establish the developed DBD-CAP device is safe for rat skin exposure durations of up to 30 seconds and effective in inducing apoptosis in melanoma cells. This study supports CAP's optimization for clinical applications and its integration with existing therapies for enhanced outcomes. However, further study is needed to examine the possible risks associated with using CAP devices in the biomedical field.
