Background/Aims: Although numerous noninvasive steatosis indices have been developed to assess hepatic steatosis, whether they can be applied to young adults in the evaluation of metabolic dysfunction-associated steatotic liver disease (MASLD) remains uncertain. Methods: Data from patients under 35 years of age who visited the Liver Health Clinic at the Armed Forces Goyang Hospital between July 2022 and January 2024 were retrospectively collected. Steatosis was diagnosed on the basis of a controlled attenuation parameter score ≥250dB/m. MASLD was defined as the presence of steatosis in patients with at least one cardiometabolic risk factor. Results: Among the 1,382 study participants, 901 were diagnosed with MASLD. All eight indices for diagnosing steatosis differed significantly between the MASLD and non-MASLD groups (p<0.001). Regarding the predictive performance, the hepatic steatosis index (HSI), fatty liver index (FLI), Framingham steatosis index, Dallas steatosis index, Zhejiang University index, lipid accumulation product, visceral adiposity index, and triglyceride glucose-body mass index exhibited an area under the curve of 0.898, 0.907, 0.899, 0.893, 0.915, 0.869, 0.791, and 0.898, respectively. The cutoff values for the FLI and HSI were re-examined, indicating a need for alternative cutoff values for the HSI, with a rule-in value of 42 and a rule-out value of 36 in this population. Conclusions This study presents novel findings regarding the predictive performance of established steatosis markers in young adults. Alternative cutoff values for the HSI in this population have been proposed and warrant further validation.

Early-life stress (ES) leads to cognitive dysfunction in female adolescents, but the underlying neural mechanisms remain elusive. Recent evidence suggests that the cell adhesion molecules NECTIN1 and NECTIN3 play a role in cognition and ES-related cognitive deficits in male rodents. In this study, we aimed to investigate whether and how nectins contribute to ES-induced cognitive dysfunction in female adolescents. Applying the well-established limited bedding and nesting material paradigm, we found that ES impairs recognition memory, suppresses prefrontal NECTIN1 and hippocampal NECTIN3 expression, and upregulates corticotropin-releasing hormone (Crh) and its receptor 1 (Crhr1) mRNA levels in the hippocampus of adolescent female mice. Genetic experiments revealed that the reduction of dorsal CA1 (dCA1) NECTIN3 mediates ES-induced object recognition memory deficits, as knocking down dCA1 NECTIN3 impaired animals' performance in the novel object recognition task, while overexpression of dCA1 NECTIN3 successfully reversed the ES-induced deficits. Notably, prefrontal NECTIN1 knockdown did not result in significant cognitive impairments. Furthermore, acute systemic administration of antalarmin, a CRHR1 antagonist, upregulated hippocampal NECTIN3 levels and rescued object and spatial memory deficits in stressed mice. Our findings underscore the critical role of dCA1 NECTIN3 in mediating ES-induced object recognition memory deficits in adolescent female mice, highlighting it as a potential therapeutic target for stress-related psychiatric disorders in women.

Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

Purpose: The use of gallium-68 prostate-specific membrane antigen-11 positron emission tomography/computed tomography (Ga-68 PSMA-11 PET/CT) is becoming increasingly common among men with prostate cancer (PCa). However, it remains uncertain which patients will derive the most benefit, and there is a scarcity of real-world data regarding its impact on altering treatment plans. This study investigated which patients would most benefit from Ga-68 PSMA-11 PET/CT, focusing on detection rates and changes in treatment strategies, drawing from a single-center experience. Materials and Methods: In total, 230 men with PCa who underwent Ga-68 PSMA-11 PET/CT between November 2021 and August 2022 were included in this retrospective study. The patients were classified into 5 groups based on their disease status: group 1, further work-up for high-risk localized PCa; group 2, de novo metastatic PCa; group 3, biochemical recurrence after definitive treatment; group 4, castration-resistant PCa; group 5, others. The positivity rate, positive lesions, predictive value of lymph node metastases, comparison with conventional images, and treatment changes after Ga-68 PSMA-11 PET/CT were analyzed in each group. Results: Of the 230 patients, 40 (17.4%), 20 (8.7%), 77 (33.5%), 76 (33.0%), and 17 (7.4%) were classified into groups 1–5, respectively. Ga-68 PSMA-11 PET/CT showed lesions in 74.8% of patients, and the optimal cutoff value for PSA was 1.99 ng/mL. Lesions not observed on conventional imaging were found in 62 patients (33.2%). In 38 patients (13.5%), treatment was changed due to Ga-68 PSMA-11 PET/CT. Conclusions These real-world data suggest that Ga-68 PSMA-11 PET/CT may be clinically useful for various disease conditions, as substantial stage migration and subsequent treatment changes occur in men with PCa. However, the prognostic impact of this modality remains unclear; thus, a well-designed prospective study is needed to address this issue.

BACKGROUND: The skin, a vital organ protecting against microorganisms and dehydration, undergoes structural decline with aging, leading to visible issues such as wrinkles and sagging. Reduced blood vessels exacerbate vulnerability, hindering optimal cellular function and compromising skin health. Polydioxanone (PDO) biomaterials address aging concerns but produce acidic byproducts, causing inflammation. Inorganic particles and nitric oxide (NO) play crucial roles in inhibiting inflammation and promoting skin regeneration. Stem cell-derived extracellular vesicles (EVs) contribute to intercellular communication, offering the potential to enhance cell functions. The study proposes a method to enhance PDO-based medical devices by incorporating inorganic particles and immobilizing EVs, focusing on facial rejuvenation, anti-inflammatory response, collagen formation, and angiogenesis.METHOD: PDO composites with inorganic particles such as magnesium hydroxide (MH) and zinc oxide (ZO) were prepared and followed by EV immobilization. Comprehensive characterization included biocompatibility, anti-inflammation, collagen formation ability, and angiogenesis ability. RESULTS: Bulk-modified PDO composites demonstrated even dispersion of inorganic particles, pH neutralization, and enhanced biocompatibility. EVs immobilized on the composite surface exhibited spherical morphology. Inflammationrelated gene expressions decreased, emphasizing anti-inflammatory effects. Collagen-related gene and protein expressions increased, showcasing collagen formation ability. In addition, angiogenic capabilities were notably improved, indicating potential for skin rejuvenation. CONCLUSION The study successfully developed and characterized PDO composites with inorganic particles and EVs, demonstrating promising attributes for medical applications. These composites exhibit biocompatibility, anti-inflammatory properties, collagen formation ability, and angiogenic potential, suggesting their utility in skin rejuvenation and tissue engineering. Further research and clinical validation are essential.

Purpose: We sought to report the results of 0.625%/0.1 mL of povidone–iodine (PI) intravitreal injection (0.013% PI vitreous concentration) for treating acute endophthalmitis after cataract surgery.Case summary: Case 1 developed acute endophthalmitis one day after cataract surgery. Prompt intervention with PI injection and vitrectomy led to full resolution of inflammation and a visual acuity of 0.8, and the patient remained stable at 10 months. Case 2, a patient with persistent post-cataract inflammation, was treated with PI injection and vitrectomy, resulting in complete resolution of inflammation and improvement of visual acuity to 0.6 by eight months. Case 3 was a diabetic patient who experienced severe acute endophthalmitis.The patient was treated with the above intervention, resulting in full resolution of endophthalmitis; however, he eventually lost vision due to neovascular glaucoma. Case 4 developed recurrent endophthalmitis caused by Achromobacter xylosoxidans after cataract surgery. This patient required multiple vitrectomies, PI injections, and intraocular lens removal, which led to a resolution of inflammation and restoration of visual acuity to 1.0 after 14 months. Conclusions 0.625%/0.1-mL IPI injection followed by vitrectomy was performed in four acute endophthalmitis patients after cataract surgery and were successfully treated.

Objective:To investigate the effect of modified Retzius-sparing robot-assisted radical prostatectomy(RS-RARP) and " Sandwich" technique of total urethral reconstruction on the early postoperative urinary continence.Methods:The clinical data of 70 consecutive patients who underwent RS-RARP by the same operator at the Cancer Hospital of the Chinese Academy of Medical Sciences from October 2021 to November 2023 were retrospectively analyzed. The age was (65.1±8.0) years old, the body mass index (BMI) was (25.6±3.1) kg/m 2, the prostate volume was (31.9±18.1)ml and the preoperative prostate specific antigen(PSA) was (16.3±16.1)ng/ml. Four patients treated with neoadjuvant hormonal therapy before radical prostatectomy. Eleven patients underwent radical prostatectomy without prostate biopsy, while the remaining 59 patients underwent prostate biopsy. There were 10, 23, 14, 10 and 2 patients with Gleason scores of 6, 7, 8, 9 and 10 respectively.There were 48 patients with clinical stage cT 2 and 22 with cT 3. The surgical method was RS-RARP and "Sandwich" technique of total urethral reconstruction. The operation time, intraoperative blood loss, postoperative drain tube preservation time, postoperative hospitalization time, pathological staging and positive margin rate, and recovery of urinary continence immediately after postoperative catheter removal were recorded. Results:In this study, all 70 surgeries were successfully completed, with no cases converted to anterior approach radical surgery or open surgery, and no serious intraoperative complications such as post-shamus hemorrhage or ureteric/rectal injury. The median postoperative follow-up was 14(3, 28) months, and there were no cases of readmission for surgical complications. The duration of surgery was (89.8±19.5) min, and the blood loss volume was (53.7±25.2)ml. The duration of drainage tube after surgery was (6.7±1.8)d, the duration of hospitalization after surgery was (7.1±1.9)d, and the duration of urinary catheter was (8.9±3.0)d. Immediate urinary continence was achieved in 50 cases when the catheter was removed, and the rate of immediate urinary continence was 71.4%(50/70). Postoperative urinary continence rate was 81.4% (57/70) at 1 month after surgery, and 90.0% (63/70) at 3 months after surgery.At 1 month postoperatively, 94.3% (66/70) of patients had a PSA <0.2 ng/ml. At 3 months postoperatively, 98.5% (69/70) of patients had a PSA <0.2 ng/ml.Conclusions:The RS-RARP and "Sandwich" technique of total urethral reconstruction is technically feasible for patients with localized prostate cancer.The short-term follow-up effect of tumor control and urinary continence are satisfactory.
