Orexins/hypocretins (Orx/Hcrt) are hypothalamic peptides that regulate a wide range of physiological processes and have been shown to be recruited by drugs of abuse. This study was designed to test the effect of the specific Orx/Hcrt receptor-1 (Hcrt-r1) antagonist, N-(2-methyl-6-benzoxazolyl)-N'-1,5-naphthyridin-4-yl urea (SB334867), on reinstatement elicited by ethanol (EtOH)-associated stimuli versus stimuli associated with a conventional reinforcer [i.e. SuperSac, consisting of 3% glucose and 0.125% saccharin (w/v)]. SB334867 (1-10 mg/kg, i.p.) dose-dependently reduced reinstatement induced by the EtOH- but not SuperSac-associated stimuli. These findings support a differential role of Hcrt-r1 in mediating EtOH seeking versus natural reward seeking.

Analysis of the morbidity characteristics and related factors of pulmonary nodules in patients with type 2 diabetes mellitus: a retrospective study.
BMC Endocr Disord
January 2025
Dongzhimen Hospital, Affiliated to Beijing University of Chinese Medicine, Beijing, 100700, China.
Objective: To analyze the characteristics of pulmonary nodules (PNs) and related influencing factors in patients with type 2 diabetes mellitus (T2DM).
Methods: Retrospectively analyzed the clinical and biochemical characteristics of 224 patients with PNs and 488 patients with non-PNs in patients with T2DM, and compared the clinical data of 72 patients with large nodules (≥ 5 mm) and 152 patients with small nodules (< 5 mm) in the pulmonary nodules (PNs) group.
Results: Compared to the non-PNs group, the PNs Patients in the group had a longer duration of diabetes, higher age, serum creatinine (SCR), blood urea nitrogen (BUN) and the lower albumin (ALB) and body mass index (BMI); women, diabetic retinopathy (DR), diabetic peripheral neuropathy (DPN), and estimated glomerular filtration rate (eGFR) < 60 ml/min1.
Hyperuricemia prevalence and its risk factors in uremic patients undergoing maintenance hemodialysis.
BMC Nephrol

Department of Nephrology, Jinshan Hospital Affiliated to Fudan University, Shanghai, China.
Background: To explore the prevalence of hyperuricemia and its associated factors in uremic patients undergoing maintenance hemodialysis (MHD).
Methods: Two hundred two uremic patients undergoing MHD for ≥ 3 months, in Jinshan Hospital, Fudan University, were enrolled. Pre-dialysis blood samples were tested during March 1st, 2023 to April 30th, 2023.
Ursodeoxycholic acid protects against sepsis-induced acute kidney injury by activating Nrf2/HO-1 and inhibiting NF-κB pathway.
BMC Nephrol
January 2025
Department of Intensive Care Medicine, No. 971st Hospital of the People's Liberation Army Navy, Qingdao, Shandong Province, PR China.
Background: Ursodeoxycholic acid (UDCA), traditionally recognized for its hepatoprotective effects, has also shown potential in protecting kidney injury. This study aimed to evaluate the protective effects of UDCA against sepsis-induced acute kidney injury (AKI) and to elucidate the underlying mechanisms.
Methods: Sixty male C57BL/6 N mice were utilized to establish a sepsis-induced AKI model through intravenous injection of lipopolysaccharides (LPS, 10 mg/kg).
Unanchored simulated treatment comparison on survival outcomes using parametric and Royston-Parmar models with application to lenvatinib plus pembrolizumab in renal cell carcinoma.

January 2025
Clifton Insight, Bristol, UK.
Background: Population-adjusted indirect comparison using parametric Simulated Treatment Comparison (STC) has had limited application to survival outcomes in unanchored settings. Matching-Adjusted Indirect Comparison (MAIC) is commonly used but does not account for violation of proportional hazards or enable extrapolations of survival. We developed and applied a novel methodology for STC in unanchored settings.

Background: Although extracorporeal membrane oxygenation (ECMO) is an effective technique for life support, the incidence of acute kidney injury (AKI) during ECMO support remains high. Dexmedetomidine (DEX), which has been widely used for sedation during ECMO, possesses several properties that help reduce the occurrence of AKI. This study aimed to investigate the protective effect of DEX on kidney function during ECMO.
