Background: Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing mild hypercapnia during the recovery period on the emergence time after total IV anesthesia (TIVA). Methods: Adult patients undergoing transurethral lithotripsy under TIVA were randomly allocated to normocapnia group (end-tidal carbon dioxide [ETCO2] 35–40 mmHg) or mild hypercapnia group (ETCO2 50-55 mmHg) during the recovery period. The primary outcome was the extubation time. The spontaneous breathing-onset time, voluntary eye-opening time, and hemodynamic data were collected. Changes in the cerebral blood flow velocity in the middle cerebral artery were assessed using transcranial Doppler ultrasound. Results: In total, 164 patients completed the study. The extubation time was significantly shorter in the mild hypercapnia (13.9 ± 5.9 min, P = 0.024) than in the normocapnia group (16.3 ± 7.6 min). A similar reduction was observed in spontaneous breathing-onset time (P = 0.021) and voluntary eye-opening time (P = 0.008). Multiple linear regression analysis revealed that the adjusted ETCO2 level was a negative predictor of extubation time. Middle cerebral artery blood flow velocity was significantly increased after ETCO2 adjustment for mild hypercapnia, which rapidly returned to baseline, without any adverse reactions, within 20 min after extubation. Conclusions Mild hypercapnia during the recovery period significantly reduces the extubation time after TIVA. Increased ETCO2 levels can potentially enhance rapid recovery from IV anesthesia.

Post transplantation diabetes mellitus(PTDM)is one of the common complications after kidney transplantation,with an incidence rate of 4%to 30%.The pharmacological treatment of PTDM after kidney transplantation faces many challenges.It is necessary to consider not only the blood glucose-lowering efficacy of the drugs themselves,but also the impact of the drugs on the function of the transplant kidney.At the same time,the interaction between antihyperglycemic drugs and immunosuppressive agents should be taken into account.Glucagon-like peptide-1 receptor agonist(GLP-1RA)have been widely used for blood glucose control in patients with type 2 diabetes mellitus.Some GLP-1RA can also improve the renal and cardiovascular outcomes of patients,and they have multiple metabolic benefits,such as regulating the lipid and reducing body weight.Clinical studies have suggested that GLP-1RA can be used for blood glucose control in kidney transplant recipients with PTDM,with multiple benefits,including reducing the risk of kidney disease and adverse cardiovascular events,as well as improving metabolism.Moreover,no influence of GLP-1RA application on the blood concentration of immunosuppressive agents in kidney transplant recipients with PTDM has been found.Given the good application potential of GLP-1RA in the treatment of kidney transplant recipients with PTDM,this article reviews the current status and future prospects of GLP-1RA treatment for PTDM,analyzes the differences in effects of different GLP-1RA,and explores their potential mechanisms of action in renal protection and multiple metabolic benefits,providing a basis for clinical application.

Background and Aims:N6-methyladenosine(m6A)epigenetic modification plays a crucial role in post-transcriptional gene expression regulation and various physiological and pathological processes,including tumorigenesis.The m6A reader IGF2BP2 significantly enhances mRNA stability and translation efficiency and is abnormally expressed in multiple cancers.However,the specific biological function of IGF2BP2 in pancreatic cancer remains unclear.Therefore,this study investigated the expression of the m6A reader IGF2BP2 in pancreatic cancer and its effects on pancreatic cancer cell functions.Methods:The expression levels of m6A-related writers,erasers,and readers were analyzed using The Cancer Genome Atlas(TCGA),the Genotype-Tissue Expression(GTEX)database,and the Gene Expression Omnibus(GEO).Kaplan-Meier survival analysis was conducted to assess the relationship between IGF2BP2 expression and the prognosis of pancreatic cancer patients.Immunohistochemistry was used to validate IGF2BP2 expression in clinical specimens of pancreatic cancer tissues and adjacent normal tissues.Functional experiments,including CCK-8 assay,flow cytometry for cell cycle analysis,colony formation assay,and Transwell migration assay,were performed to evaluate changes in cell proliferation,cell cycle distribution,colony formation ability,and migration capacity after IGF2BP2 knockdown in pancreatic cancer cells.Results:TCGA-GTEX and GEO database analyses showed that IGF2BP2 was highly expressed in pancreatic cancer tissues(both P<0.05)and that its high expression was associated with poor overall survival(both P<0.05).Immunohistochemical staining of clinical specimens confirmed that IGF2BP2 protein expression was higher in pancreatic cancer than in adjacent normal tissue.Functional experiments demonstrated that IGF2BP2 knockdown significantly reduced the proliferation ability of pancreatic cancer cells,arrested more cells in the G0-G1 phase,decreased colony formation,and impaired cell migration(all P<0.05).Conclusion:The m6A reader IGF2BP2 is highly expressed in pancreatic cancer tissues and is closely associated with poor prognosis in patients with this disease.Its mechanism of action may be related to the promotion of cancer cell growth and migration.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To investigate the current situation of water-borne endemic fluorosis in Anhui Province, and provide basic data for the adjusting the prevention and control measures.Methods:Using cross-sectional survey method, all villages in the water-borne endemic fluorosis areas were investigated in Anhui Province from 2019 to 2022. In water-borne endemic fluorosis village, the situation of water improvement project and the fluoride level of drinking water were investigated, and dental fluorosis of all children aged 8 - 12 was examined. The criteria for determining the achievement of control targets for water-borne endemic fluorosis in affected counties were based on the "Evaluation Measures for Control and Elimination of Key Endemic Diseases (2019 Edition)".Results:From 2019 to 2022, the rate of water improvement village in water-borne endemic fluorosis areas were 88.47% (1 527/1 726), 100% (1 726/1 726), 100% (1 726/1 726) and 100% (1 726/1 726), respectively. The qualified proportion of water fluoride in water-borne endemic fluorosis villages was 33.84% (584/1 726), 63.09% (1 089/1 726), 70.74% (1 221/1 726) and 74.33% (1 283/1 726), respectively. The prevalence rates of dental fluorosis in children aged 8 - 12 were 25.48% (45 461/178 440), 15.78% (27 959/177 200), 13.68% (23 505/171 880) and 12.66% (23 315/184 200), respectively. The proportion of affected counties that had achieved the control target of water-borne endemic fluorosis was 16% (4/25), 60% (15/25), 36% (9/25) and 40% (10/25), respectively.Conclusions:The water-borne endemic fluorosis areas in Anhui Province have improved the water fluoride qualification rate and reduced the incidence of fluorosis in children through prevention and control measures such as water improvement and fluoride reduction. However, the prevention and control efforts in key areas and counties need to be further improved.
