The incidence of metabolic dysfunction-associated steatotic liver disease (MASLD) has been escalating annually, positioning it as the leading cause of chronic liver disease worldwide. Ursolic acid has demonstrated promising therapeutic efficacy in managing MASLD, thereby justifying the need for an in-depth exploration of its pharmacological mechanisms. This study aimed to investigate elucidate the therapeutic mechanisms by which ursolic acid modulates estrogen conversion in the treatment of MASLD.

Building upon prior studies that have highlighted the potent anti-inflammatory effects of ursolic acid and its specific targeting of 17β-hydroxysteroid dehydrogenase 14 (HSD17B14), this investigation employed a western diet to induce MASLD in murine models with varying severities over different time intervals.

The protein expression of HSD17B14 initially increased, followed by a subsequent decrease. This trend was accompanied by corresponding changes in 17β-estradiol (E2) and estrone (E1) levels. Intervention with ursolic acid resulted in a reduction in HSD17B14 and E1 levels during the phase of high HSD17B14 expression, while simultaneously elevating E2 levels. In steatotic hepatocytes, E1 promoted cellular inflammation, whereas E2 exhibited anti-inflammatory effects. However, the alleviated effects of E2 were antagonized by HSD17B14. As expected, ursolic acid modulated HSD17B14, thereby mitigating the inflammatory response in steatotic hepatocytes.

HSD17B14, a crucial enzyme regulating the balance between E1 and E2, catalyzes the conversion of estrogen E2 into E1, thereby exacerbating tissue inflammation induced by metabolic stress. Ursolic acid, by modulating HSD17B14-mediated estrogen conversion, appears to ameliorate immune-related inflammation in MASLD.

Poor bioavailability and a short half-life limit the therapeutic efficacy of ibuprofen. This study developed floating nanoballoons to enhance ibuprofen’s bioavailability and sustain its anti-inflammatory effects through improved gastric retention.

Ibuprofen-loaded nanoballoons were synthesized using solvent evaporation with ethyl cellulose as the polymer matrix. The formulation was characterized for morphology, buoyancy, drug loading, and release kinetics. In vivo studies assessed the anti-inflammatory efficacy in acute and chronic inflammation models using male Sprague-Dawley rats.

The nanoballoons exhibited optimal characteristics, including 96% buoyancy and a drug loading efficiency of 96.54 ± 1.32%. Scanning Electron Microscopy revealed a spherical morphology with a porous structure. Drug release followed a biphasic pattern: an initial release of 35.23 ± 2.13% over 2 h, followed by sustained release reaching 97.54 ± 1.30% at 12 h. In acute inflammation studies, the nanoballoon formulation showed superior edema inhibition (68.12%) compared to pure ibuprofen (51.67%). Chronic inflammation studies demonstrated significant improvements in inflammatory markers: reduced TNF-α (19.12 ± 0.48 vs. 31.11 ± 1.23 pg/mL), hs-CRP (201.7 ± 11.02 vs. 232.12 ± 11.33 ng/mL), and IL-6 (100.01 ± 18.40 vs. 135 ± 11.22 pg/mL), with increased anti-inflammatory IL-10 (507.18 ± 10.11 vs. 276.11 ± 19.16 pg/mL).

The developed floating nanoballoon system significantly enhanced ibuprofen’s bioavailability and anti-inflammatory efficacy, presenting a promising gastro-retentive delivery platform for poorly water-soluble drugs.

This review explores the integration of complexity science—specifically, the biological holographic phenomenon and chaos-fractal theory—with the fundamental principles of traditional Chinese medicine (TCM) to optimize perioperative recovery. It examines how these theories provide a scientific foundation for developing a digital TCM diagnosis and treatment platform. Key topics discussed include the application of digital four-diagnosis technology, visualization of perioperative Yin-Yang states, and artificial intelligence-driven biomarker discovery. By quantifying and digitizing core TCM concepts, this approach enables their incorporation into Enhanced Recovery After Surgery protocols. Ultimately, the review highlights the potential of integrating TCM with Western medicine to advance personalized postoperative management, offering both theoretical insights and practical strategies for improving perioperative care.

Paget’s disease of the esophagus is extremely rare, with few cases reported. In this report, we describe a case of recurrent esophageal Paget’s disease coexisting with small cell carcinoma. A 63-year-old man presented with the chief complaint of a rediscovered early esophageal cancer. Endoscopic examination revealed two separate superficial flat tumors in the upper and mid esophagus. Endoscopic submucosal dissection was performed, diagnosing diffuse Paget’s disease (5.5 × 3.5 cm) and a small focus on intramucosal squamous cell carcinoma, respectively. Paget’s cells were also found in the distal and right margins of the first specimen of endoscopic submucosal dissection. Immunohistochemical analysis showed that Paget’s disease diffusely expressed cytokeratin 7 (CK7), CK18, and mucin 6 (MUC6), and focally expressed CD56 and chromogranin A, but not CK5/6, p63, p40, MUC5AC, MUC2, or synaptophysin. A complete absence of p53 and Rb1 was observed in Paget’s disease. However, overexpression of p53 and retention of Rb1 were seen in squamous cell carcinoma. Approximately 27 months later, a prominent tumor was found at the same location as the previous Paget’s disease. Subsequently, radical surgery was performed, and the final pathological evaluation revealed esophageal small cell carcinoma coexisting with Paget’s disease. Moreover, both p53 and Rb1 were completely absent in both Paget’s disease and the small cell carcinoma. This suggests that esophageal Paget’s disease may dedifferentiate and develop into small cell carcinoma. In conclusion, esophageal Paget’s disease can co-occur with invasive carcinomas, including small cell carcinoma, and should be completely resected endoscopically, with close follow-up.

Insulinoma is a neuroendocrine tumor originating in the pancreas that secretes excess amounts of insulin, leading to severe hypoglycemia. The clinical presentation of hypoglycemia is classically described by Whipple’s Triad. Due to the rarity of this diagnosis, it can often be mistaken for other etiologies with similar presentations. In this paper, we present the case of a woman in her 70s with metastatic insulinoma involving the liver, who was initially diagnosed with an insulin-like growth factor 2-secreting hepatocellular carcinoma. Biochemical and immunohistochemical analyses were instrumental in distinguishing between these two etiologies.

Epidemiological data on bacterial infections in cirrhosis in China remain limited. Therefore, we aimed to conduct a multicenter study to investigate the characteristics and outcomes of patients with cirrhosis and bacterial infections in China.

We retrospectively enrolled 1,438 hospitalized adult patients with cirrhosis and bacterial or fungal infections from 24 hospitals across China between January 2018 and September 2024. Data on demographics, clinical features, microbiology, treatment, and outcomes were collected.

A total of 1,783 infection episodes were recorded, including 1,668 first infections and 115 second infections. Most infections were community-acquired (86.6%). Pneumonia was the most common infection type (26.7%), followed by spontaneous bacterial peritonitis (19.5%) and spontaneous bacteremia (14.1%). Among 754 pathogens isolated from 620 patients, Klebsiella pneumoniae (20.1%) was nearly as common as Escherichia coli (21.7%). Multidrug-resistant (MDR) organisms accounted for 41.0% of all isolates, with extended-spectrum β-lactamase-producing Escherichia coli being the most prevalent MDR strain (8.9% of patients). Adherence to empirical antibiotic treatment guidelines from the European Association for the Study of the Liver was significantly lower in this cohort compared to the global study (21.5% vs. 61.2%, P < 0.001), accompanied by a lower clinical resolution rate (63.5% vs. 79.8%, P < 0.001).

The clinical and microbiological characteristics of bacterial infections in patients with cirrhosis in China differ substantially from those reported in other regions. These findings highlight the need for region-specific management and prevention strategies, particularly in light of the changing microbiological landscape, high MDR prevalence, and suboptimal antibiotic practices.

Hepatic biliary adenofibroma is an exceedingly rare biliary neoplasm that primarily affects adults. It typically presents as a solitary mass composed of low-grade microcystic and tubuloglandular bile duct structures, which are lined by low columnar to cuboidal non-mucin-producing biliary epithelium and supported by abundant fibrous stroma. Histologically, it resembles the Von Meyenburg complex but is much larger in size and often shows cytologic atypia. Although considered benign, emerging case studies and analyses suggest that biliary adenofibroma may serve as a precursor lesion to intrahepatic cholangiocarcinoma. However, its extreme rarity, coupled with an incompletely understood histogenesis, perpetuates diagnostic uncertainty and may lead to misclassification with other similar entities. This review consolidates the current understanding of the histopathological and molecular characteristics of biliary adenofibroma, highlights its differential diagnosis, explores its potential progression to cholangiocarcinoma, and discusses unresolved questions while proposing future research directions.

Ischemic colitis has been previously associated with the use of certain medications; however, no cases have been reported in connection with zolmitriptan. This study aimed to describe a case of ischemic colitis associated with zolmitriptan use. A 56-year-old female patient taking zolmitriptan presented to the hospital with complaints of abdominal pain, bloody diarrhea, and emesis. Colonoscopy and abdominal imaging with computed tomography revealed findings consistent with ischemic colitis. After recognizing the association between ischemic colitis and zolmitriptan use, the medication was discontinued, and the patient recovered with supportive therapy. This is the first reported case of ischemic colitis associated with zolmitriptan.

Mucinous cystic neoplasms (MCNs) are rare pancreatic lesions that often go undiagnosed due to their asymptomatic nature. Though typically benign, they can harbor malignant potential, making early detection and treatment essential. This case report presents a 32-year-old female with intermittent epigastric pain, who was found to have a cystic lesion in the pancreatic tail, diagnosed as an MCN through endoscopic ultrasound and fine-needle aspiration. The patient underwent a spleen-sparing distal pancreatectomy, which was complicated by a peri-pancreatic abscess that required drainage. This case highlights the importance of distinguishing MCNs from other pancreatic cystic lesions, as misdiagnosis or delayed intervention can lead to adverse outcomes. It underscores the need for vigilant diagnostic imaging and individualized treatment strategies, particularly in young patients, to avoid unnecessary morbidity and ensure optimal outcomes. The report contributes to the growing understanding of MCNs, emphasizing early diagnosis, tailored surgical management, and the significance of postoperative care.
