Purpose: To evaluate the prognostic value of pretreatment serum γ-glutamyltransferase (GGT) level in patients with advanced hepatocellular carcinoma (HCC) receiving transarterial chemoembolization.
Materials And Methods: This retrospective study included 140 patients (123 male, 17 female; mean age, 56.9 y ± 12.0; range, 22.0-82.0 y) with Barcelona Clinic Liver Cancer class C HCC who received first-line conventional chemoembolization between December 2013 and March 2018. Patients were divided into low and high GGT groups based on a cutoff value calculated with a receiver operating characteristic curve. Overall survival (OS) was compared between groups by log-rank test. Univariate and multivariate survival analyses were performed.
Results: The optimal cutoff values of GGT were 119.5 U/L in men and 175.0 U/L in women. The 6-, 9-, and 12-mo OS rates were 81.7%, 72.4%, and 62.9%, respectively, for patients in the low GGT group (n = 44) and 58.8%, 35.7%, and 28.8%, respectively, for patients in the high GGT group (n = 96; P < .001). Multivariable Cox regression analysis identified high pretreatment serum GGT level (hazard ratio [HR], 2.71; 95% confidence interval [CI], 1.67-4.40; P < .001), multiple tumors (HR, 3.05; 95% CI, 1.23-7.53; P = .02), and performance of target treatment (ie, sorafenib; HR, 0.41; 95% CI, 0.24-0.72; P = .002) or ablation (HR, 0.35; 95% CI, 0.18-0.66; P = .001) as independent prognostic factors for OS.
Conclusions: Pretreatment serum GGT level was an independent prognostic factor for OS in patients with advanced HCC treated with chemoembolization, suggesting that GGT is a useful prognostic biomarker for advanced HCC.

Limb lengthening and deformity correction techniques, particularly distraction osteogenesis, have significantly evolved in pediatric orthopedics. This study examines the temporal changes of key biochemical markers-vascular endothelial growth factor (VEGF), fibroblast growth factor 1 (FGF-1), and the propeptide of type I collagen (P1NP)-during the limb lengthening process. Twenty pediatric patients (aged 13-16) underwent distraction osteogenesis using the Circular Hexapod External Fixator.

Objective: To evaluate the correlation between response assessment measured by PET/CT with [F] F-fluorocholine (Choline PET/CT) and serum levels of PSA in patients with prostate cancer under antiandrogenic treatment.
Methodology: A retrospective study included patients with CRPC and CSPC treated with enzalutamide, abiraterone, or apalutamide between June 2018 and July 2021, who underwent baseline and a follow-up Choline PET/CT. The difference in maximum SUVmax (ΔSUV) between both studies and the PSA value before and at follow-up were recorded.
In vivo toxic and lethal cardiorespiratory effects of a synthetic quaternary ammonium salt derivative of haloperidol in mice.

Department of Pharmacology, Shantou University Medical College, Shantou, Guangdong, China.
Background: To investigate the toxicity of N-n-butyl haloperidol iodide (F2), a quaternary ammonium salt derivative of haloperidol, in mice for potential therapeutic purposes.
Methods: The acute median lethal dose (LD) of F2 was determined using the Bliss method following intravenous administration in mice. Routine surface electrocardiograms (ECGs) and arterial blood pressures (aBPs) were recorded under general anesthesia in untreated and pharmacologically vagotomized mice injected with F2.
Introduction: This study explored the effects of four different surgical methods in the treatment of cesarean scar pregnancy (CSP).
Methods: In this multicenter retrospective analysis of 359 patients, the surgical indices, the time taken for the serum human chorionic gonadotropin level to return to normal, the recovery time of menstruation, and the incidence of postoperative adverse reactions were comparatively analyzed. The clinical efficacies of various preoperative treatment methods to block the blood supply to CSP tissues and those of four different surgical methods to treat CSP, namely, curettage, hysteroscopic surgery, laparoscopic surgery, and vaginal surgery, were evaluated in this study.
VDAC1 Cleavage Promotes Autophagy in Renal Tubular Epithelial Cells With Hypoxia/Reoxygenation Injury.

Aim: To study the effect and elucidate the underlying mechanisms of VDAC1-ΔC on autophagy in renal tubular epithelial cells injured by hypoxia/reoxygenation.
Methods: C57/BL6 mice were randomly divided into groups: sham operation group, IRI 1d group and IRI 2d group. The inner canthal blood of mice was collected to detect the levels of serum creatinine and urea nitrogen and kidney tissues were sampled, and sections were stained with Periodic acid-Schiff for morphological evaluation.
