Background: Flow-mediated dilation (FMD) is commonly used as a diagnostic tool to assess endothelial function, and compared with other methods for stimulating radial artery dilation, FMD offers several advantages such as non-invasiveness, ease of execution, minimal equipment requirements, and negligible risk. The study aimed to investigate the effect of FMD in facilitating radial arterial cannulation in the context of intravenous general anesthesia.

Methods: Eighty patients undergoing intravenous general anesthesia and requiring radial artery cannulation were randomized 1:1 to the FMD group and control group.

Objective: Protein kinase C (PKC) has been implicated in the increased contraction of human airway smooth muscle cells (HASMCs) in asthma. Using the three-dimensional collagen gel contraction system, the study aimed to determine the effects of LY333531, a specific inhibitor of the PKC-β isoform, on the contraction of tumor necrosis factor (TNF)-α-sensitized HASMCs.

Methods: Cultured HASMCs were divided into five groups: the control group received no treatment, and the cells in the TNF-α group were sensitized with 10 ng/mL TNF-α for 48 h, while TNF-α was administered to sensitize HASMCs in the presence of 0.

Background: Balanced propofol sedation is extensively used in endoscopic retrograde cholangiopancreatography (ERCP), but sedation-related adverse events (SRAEs) are common. In various clinical settings, the combination of dexmedetomidine with opioids and benzodiazepines has provided effective sedation with increased safety. The aim of this investigation was to compare the efficacy and safety of dexmedetomidine and propofol for sedation during ERCP.

Article Synopsis
  • - The study investigates whether alfentanil, a shorter-acting opioid, can reduce the cough commonly caused by sufentanil during anesthesia induction for thyroid surgery.
  • - Eighty patients were divided into two groups: one receiving alfentanil before sufentanil and the other receiving normal saline. The results showed that the incidence of cough was significantly lower in the alfentanil group (5%) compared to the normal saline group (40%).
  • - No major differences were observed between the two groups regarding side effects, intraoperative hemodynamics, or recovery issues, indicating that alfentanil effectively minimizes sufentanil-induced cough without other adverse effects.

Iron accumulation, which is controlled by transferrin receptor 1 (TfR1), modulates hypoxia-inducible factor-1α (HIF-1α) activation and angiogenesis of hypoxic endothelial cells. The study examined the role of protein interacting with C-kinase 1 (PICK1), a scaffold protein containing PDZ domain, in regulating glycolysis and angiogenesis of hypoxic vascular endothelial cells through its potential effect on TfR1, which features a supersecondary structure that interacts with the PDZ domain. Iron chelator deferoxamine and TfR1 siRNA were employed to assess the impact of iron accumulation on angiogenesis, while the effects of PICK1 siRNA and overexpressing lentivirus on TfR1-mediated iron accumulation were also investigated in hypoxic human umbilical vein vascular endothelial cells (HUVECs).

Background: Umbilical artery serum-derived exosomes (UEs) serve as messengers for maternal-fetal information exchange and cellular regulation. Intravenous remifentanil could be considered as an effective adjunct to epidural anesthesia in providing a favorable analgesia effect for cesarean section (C-section), but its effects on UEs are currently unknown.

Methods: From 01/12/2021 to 30/06/2022, eligible parturients scheduled for repeated C-section at the First Affiliated Hospital of Wenzhou Medical University were randomized to receive either an intravenous bolus (0.

Article Synopsis
  • RIPK1 plays a crucial role in apoptosis by regulating proteins like Bax and Bak, but its influence on Bok in muscle ischemia reperfusion (IR) injury was uncertain.
  • The study involved rats divided into four groups to assess the effects of RIPK1 inhibition via necrostatin-1 during induced skeletal muscle IR injury, evaluating muscle damage and protein expression.
  • Results indicated that necrostatin-1 significantly reduced muscle damage and apoptosis markers while promoting cell survival, suggesting its potential as a therapeutic approach for skeletal muscle protection during IR injury.

Background: Dynamin related protein-1 (Drp1)-mediated mitochondrial fission relates to ischemia reperfusion (IR) injury, and its association with necroptosis is implied. We hypothesized that receptor-interacting protein 1 (RIP1), a key kinase in necroptosis, acted as an upstream of Drp1-mediated mitochondrial fission during skeletal muscle IR.

Methods: Thirty rats were randomized into the SM, IR, NI, MI, and DI group ( = 6).

Background: Regional anesthesia such as interscalene brachial plexus block (ISBPB) with intermediate cervical plexus block (ICPB) is generally a preferred choice for clavicular surgery. However, various studies have shown that these blocks, especially ISBPB, could cause phrenic nerve paralysis and decrease diaphragmatic motion. The study aimed to evaluate the efficacy of clavipectoral fascial plane block (CPB), an alternative technique to ISBPB, with ICPB, in reducing hemidiaphragmatic paralysis during midshaft clavicular surgery.

In this work, a novel sodium silicate-modified peanut shell biochar(Si-PSB) was synthesized and used as phosphorus adsorbents. Compared with unmodified biochar(PSB), the adsorption capacity of Si-PSBs increased significantly. The adsorption capacity of 8% sodium silicate solution modified biochar(8%Si-PSB) was 3.

Background: Both apoptosis and necroptosis have been recognized to be involved in ischemia reperfusion-induced lung injury. We aimed to compare the efficacies of therapies targeting necroptosis and apoptosis and to determine if there is a synergistic effect between the two therapies in reducing lung ischemia reperfusion injury.

Methods: Forty Sprague-Dawley rats were randomized into 5 groups: sham (SM) group, ischemia reperfusion (IR) group, necrostatin-1+ischemia reperfusion (NI) group, carbobenzoxy-Val-Ala-Asp-fluoromethylketone+ischemia reperfusion (ZI) group, and necrostatin-1+carbobenzoxy-Val-Ala-Asp-fluoromethylketone+ischemia reperfusion (NZ) group.

Remote ischemic pre-conditioning (RIPC) may have a protective effect on myocardial injury associated with cardiac bypass surgery (CPB). The objective of the present study was to investigate the effect of RIPC on ischemia/reperfusion (I/R) injury and to assess the underlying mechanisms. A total of 241 patients who underwent valve replacement were randomly assigned to receive either RIPC (n=121) or control group (n=120).

Objective: This study was aimed to investigate the protective effect of methylene blue against lung injury induced by reperfusion of ischemic hindlimb in a rat model.

Methods: Twenty-four healthy adult male Sprague-Dawley rats were equally randomized into three groups: sham (SM) group, ischemia reperfusion (IR) group, and methylene blue (MB) group. Rats in both IR and MB groups were subjected to 4 h of ischemia by clamping the left femoral artery and then followed by 4 h of reperfusion.

Gemin5 acts as a U1 small nuclear RNA (snRNA)-binding protein in U1 small nuclear ribonucleic protein (snRNP) biogenesis. Here, we report a role for Gemin5 in unassembled U1 snRNP disposal under survival of motor neuron (SMN) protein-deficient conditions. We demonstrate that non-Sm protein-associated U1 snRNA and U1A are enriched in cytoplasmic granules and colocalize to P bodies in SMN-deficient cells.

Reperfusion after tourniquet use can induce inflammation and cause remote organ injury. We evaluated the therapeutic effect of transcutaneous electrical acupoint stimulation (TEAS) on inflammatory mediators and lung function in patients receiving lower limb tourniquets. Forty patients undergoing unilateral lower extremity surgery with tourniquet were randomly assigned to two groups: the TEAS group and ischemia-reperfusion (I/R) group.
