Objective:
To prospectively evaluate the feasibility, accuracy, and safety of multiparameter MRI-guided percutaneous biopsy using a 1T open MRI scanner for evaluating suspicious centrally located lung lesions with associated post-obstructive atelectasis.
Materials and Methods:
In this single-center study, MRI-guided percutaneous coaxial cutting biopsy was performed for 107 suspicious central lung lesions with associated post-obstructive atelectasis in 107 patients between July 2015 and December 2020. A fast T2-weighted imaging (T2WI)-turbo spin echo (TSE) sequence and an enhanced fast T1-weighted imaging (T1WI)-TSE sequence were used to identify, localize, and biopsy lung lesions, and diffusion-weighted imaging (DWI) was used as a supplementary sequence for identifying the lesion location. The final diagnosis was confirmed by surgical histopathology or clinical follow-up for a minimum of 24 months. The sensitivity, specificity, and accuracy for diagnosing lung malignancies were calculated, and the complications were recorded for each case.
Results:
Using multiparameter MRI, central lung lesions could be clearly distinguished from post-obstructive atelectasis in 96 patients (89.7%). The sensitivity, specificity, and accuracy of MRI-guided percutaneous biopsy for diagnosing lung malignancy was 97.0% (98/101), 100% (6/6), and 97.2% (104/107), respectively. Self-limited hemoptysis occurred in three patients. Pneumothorax occurred in five patients, of which none required pleural drainage. No serious procedure-related complications were observed.
Conclusion
As a technology that does not involve ionizing radiation, multiparameter MRI-guided percutaneous coaxial cutting biopsy is a safe and accurate diagnostic technique for evaluating centrally located lung lesions associated with post-obstructive atelectasis.

OBJECTIVE To evaluate the efficacy and safety of rituximab (RTX) in the treatment of primary Sjögren syndrome (pSS). METHODS Randomized controlled trials (RCTs) on the effects of RTX (trial group) versus placebo (control group) in the treatment of pSS were searched from the Cochran Library, PubMed, Embase, Medline, Web of Science, VIP, CNKI, Wanfang, and other databases during the inception to February 2024. After literature screening and quality evaluation, meta-analysis was performed by using RevMan 5.3 software. RESULTS Seven RCTs were finally included, involving a total of 518 patients. Results of meta-analysis showed that European League Against Rheumatism Sjögren syndrome disease activity index (ESSDAI) score [MD=-1.17, 95%CI(-1.52, -0.82), P<0.000 01] and oral dryness visual analogue scale (VAS) score [MD=-3.97, 95%CI (-5.08, -2.86), P<0.000 01] in the trial group were significantly lower than the control group; unstimulated salivary flow rate [SMD=0.64, 95%CI(0.41, 0.87), P<0.000 01] and Schirmer score [MD=0.19, 95%CI(0.18, 0.20), P<0.000 01] were significantly higher than the control group. There was no statistical significance in response rate [RD=0.10, 95%CI(-0.04, 0.23), P=0.16], fatigue VAS score [MD=-12.50, 95%CI(-35.14, 10.15), P=0.28], European League Against Rheumatism Sjögren syndrome patient reported index (ESSPRI) score [MD=0.33, 95%CI(-0.53, 1.18), P=0.46], Short-form 36 health survey physical component summary (SF36-PCS) score [MD=0.90, 95%CI(-2.97, 4.78), P=0.65], SF-36 mental component summary (SF36-MCS) score [MD=0.11, 95%CI(-0.41, 0.63), P=0.68], total salivary gland ultrasound score [SMD=-1.91, 95%CI(-4.01, 0.19), P=0.07] or the incidence of adverse drug reactions [OR=1.15,95%CI(0.62,2.13),P=0.66] between 2 groups. CONCLUSIONS RTX has advantages in the improvement of ESSDAI score, unstimulated salivary flow rate, Schirmer score and oral dryness VAS score in pSS patients, and has a good safety profile. However, it did not exhibit significant improvement in fatigue VAS score, ESSPRI score, SF36-PCS score, SF36-MCS score or response rates.

Membrane-bound organelles and membraneless organelles (MLOs) coordinate various biological processes within eukaryotic cells. Among these, stress granules (SGs) are significant cytoplasmic MLOs that form in response to cellular stress, exhibiting liquid-like properties alongside stable substructures. SGs interact with diverse organelles, thereby influencing cellular pathways that are critical in both health and disease contexts. This review discusses the interplay between SGs and organelles and explores the methodologies employed to analyze interactions between SGs and other MLOs. Furthermore, it highlights the pivotal roles SGs play in regulating cellular responses and the pathogenesis of amyotrophic lateral sclerosis. Gaining insights into these interactions is essential for deciphering the mechanisms underlying both physiological processes and pathological conditions.

The NOD-like receptor protein 3 (NLRP3) inflammasome is essential in innate immune-mediated inflammation, with its overactivation implicated in various autoinflammatory, metabolic, and neurodegenerative diseases. Pharmacological inhibition of NLRP3 offers a promising treatment strategy for inflammatory conditions, although no medications targeting the NLRP3 inflammasome are currently available. This study demonstrates that clioquinol (CQ), a clinical drug with chelating properties, effectively inhibits NLRP3 activation, resulting in reduced cytokine secretion and cell pyroptosis in both human and mouse macrophages, with a half maximal inhibitory concentration (IC50) of 0.478 μM. Additionally, CQ mitigates experimental acute peritonitis, gouty arthritis, sepsis, and colitis by lowering serum levels of interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α). Mechanistically, CQ covalently binds to Arginine 335 (R335) in the NACHT domain, inhibiting NLRP3 inflammasome assembly and blocking the interaction between NLRP3 and its component protein. Collectively, this study identifies CQ as an effective natural NLRP3 inhibitor and a potential therapeutic agent for NLRP3-driven diseases.
