Abstract
General anesthesia, as a commonly used medical intervention, has been widely applied during surgical procedures to ensure rapid loss of consciousness and pain relief for patients. However, recent research suggests that general anesthesia may be associated with the occurrence of perioperative neurocognitive disorder (PND). PND is characterized by a decline in cognitive function after surgery, including impairments in attention, memory, learning, and executive functions. With the increasing trend of population aging, the burden of PND on patients and society's health and economy is becoming more evident. Currently, the clinical consensus tends to believe that peripheral inflammation is involved in the pathogenesis of PND, providing strong support for further investigating the mechanisms and prevention of PND.

Abstract
INTRODUCTION Although venovenous extracorporeal membrane oxygenation (VV ECMO) is a reasonable salvage treatment for acute respiratory distress syndrome (ARDS), it requires sedating the patient. Sevoflurane and propofol have pulmonary protective and immunomodulatory properties. This study aimed to compare the effectiveness of sevoflurane and propofol on rats with induced ARDS undergoing VV ECMO. METHODS Fifteen sprague-dawley (SD) rats were randomly divided into three groups: Con group, sevoflurane (Sevo) group and propofol (Pro) group. Arterial blood gas tests were performed at time pointsT0 (baseline), T1 (the time to ARDS), and T2 (weaning from ECMO). Oxygenation index (PaO2/FiO2) was calculated, and lung edema assessed by determining the lung wet:dry ratio. The protein concentration in bronchial alveolar lavage fluid (BALF) was determined by using bicinchoninic acid assay. Haematoxylin and eosin staining was used to evaluate the lung pathological scores in each group. IL-1β and TNF-α were also measured in the BALF, serum and lung. RESULTS Oxygenation index showed improvement in the Sevo group versus Pro group. The wet:dry ratio was reduced in the Sevo group compared with propofol-treated rats. Lung pathological scores were substantially lower in the Sevo group versus the Pro group. Protein concentrations in the BALF and levels of IL-1β and TNF-α in the Sevo group were substantially lower versus Pro group. CONCLUSION This study demonstrates that compared with propofol, sevoflurane was more efficacious in improving oxygenation and decreasing inflammatory response in rat models with ARDS subject to VV ECMO treatment.

Abstract
We are aiming to develop an electrochemical microcatheter sensor for the detection and real-time continuous monitoring of propofol (PPF), which is an anesthetic drug majorly used during medical treatment. This proposed microcatheter-based sensing strategy meets the challenge of real-time periodic and continuous monitoring of propofol by using d-Ti3C2Tx-rGO-chi-modified carbon paste microcatheter sensor transducer. The sensing methodology relies on voltammetry and chronoamperometry transduction methods. The reusable microcatheter sensor was fabricated by embedding the three electrodes into a few millimeters-wide Teflon tube. The nanocomposite was characterized using advanced analytical instruments such as XRD, FE-SEM, EDX, Raman spectroscopy, and XPS. Further, electrode interfacial properties were characterized with voltammetry and electrochemical impedance spectroscopy. The electroanalytical performance of the modified microcatheter sensor was tested for the detection of PPF in phosphate buffer by using chronoamperometry with a wide linear range of 5 to 110 µM (at an applied potential of 0.3 V vs. Ag/AgCl). The sensor's practical potency was confirmed in human serum with a dynamic linear range of 10 to 130 µM. The sensor exhibited a good limit of detection values in phosphate buffer (2 µM) and natural human plasma (4 µM). The new sensor displays different dimensions of information while displaying high sensitivity, selectivity, and long-term stability. The outstanding analytical performance of the developed sensor holds considerable promise for the continuous monitoring of propofol, its effective management, and optimization of the doses in the patient's body.

Abstract
OBJECTIVES To further investigate how sevoflurane affects the oxidative stress injury (OSI) in patients undergoing laparoscopic cholecystectomy (LC). METHODS A prospective cohort study was carried out at Shandong Provincial Third Hospital, Jinan, China on 82 gallstone patients who underwent LC, with sevoflurane maintenance during surgery. Genotyping analysis of the rs145204276 polymorphism was performed using the TaqMan platform. Oxidative stress injury and liver injury parameters were also examined. Lipopolysaccharide (LPS)-induced macrophages, which were challenged with sevoflurane, propofol, or the lncRNA-GAS5 overexpressing plasmid, were used to evaluate the effect of Sevoflurane on lncRNA-GAS5-mediated macrophage polarization. RESULTS At TM1 and TM2, the levels of OSI markers and long noncoding (lnc) RNA-GAS5 were not obviously different, whereas at the TM3 time point, these indices were significantly different between the Del-Sevoflurane and Del-Propofol subgroups. These indices were not different between the Ins-sevoflurane and Ins-Propofol subgroups at any time point. Cell-based experiments demonstrated that Sevoflurane could increased the lncRNA-GAS5 level in LPS-induced Del-macrophages (p=0.0058), but Propofol did not have this effect (p=0.847). Both Sevoflurane and Propofol did not have the effect on lncRNA-GAS5 level in LPS-induced Ins-macrophages (p=0.321 and p=0.822, respectively). CONCLUSION Sevoflurane maintenance can decrease OSI during LC in the Del genotype of the rs145204276 polymorphism. The Del genotype facilitates lncRNA-GAS5 up-regulation under Sevoflurane exposure and therefore decrease the extent of M1 macrophage polarization.

Aging (Albany NY) 2021; 13:15511-15522.

Abstract
Propofol (Pro) confers protection against renal ischemia/reperfusion (rI/R) injury through incompletely characterized mechanisms. Since Pro has shown net anti-inflammatory properties as part of its beneficial effects, we examined the potential role of Pro in the modulation of macrophage polarization status during both rI/R injury in vivo and exposure of cultured peritoneal macrophages (PMs) to hypoxia/reoxygenation (H/R). Rats were subjected to 45-min r/IR surgery or a sham procedure and administered PBS (vehicle) or Pro during the ischemia stage. Pro administration attenuated rI/R-induced kidney damage and renal TNF-α, IL-6, and CXCL-10 expression. Enhanced macrophage M2 polarization, evidenced by reduced iNOS and increased Arg1 and Mrc1 mRNA levels, was further detected after Pro treatment both in the kidney, after rI/R in vivo, and in H/R-treated PMs. Pro administration also repressed phosphorylated signal transducer and activator of transcription 1 (p-STAT1) and increased p-STAT3, p-STAT6, and peroxisome proliferator-activated receptor-γ (PPARγ) mRNA levels in H/R-exposed PMs. Importantly, siRNA-mediated PPARγ silencing repressed Pro-mediated STAT3 activation in PMs and restored proinflammatory cytokine levels and prevented macrophage M2 marker expression in both rI/R-treated rats and cultured PMs. These findings suggest that Pro confers renoprotection against rI/R by stimulating PPARγ/STAT3-dependent macrophage conversion to the M2 phenotype.
