Objectives:to analyze the efficacy of percutaneous coronary intervention(PCI)for complex left main(LM)lesions combined with chronic total occlusion(CTO)of the right coronary artery. Methods:Ninety patients with complex left main lesions hospitalized in Hunan Provincial People's Hospital from January 2019 to December 2022 were consecutively included.According to the coronary angiographic vascular lesions,patients were divided into complex left main lesions combined with right coronary artery CTO(observation group,n=30)and complex left main lesions without right coronary artery CTO(control group,n=60).The baseline clinical data,intraoperative conditions,angiographic results,and postoperative follow-up results of the patients were analyzed and compared between the two groups. Results:Fifty-eight(64.4%)out of the 90 patients were male.There was no statistically significant difference between the two groups in terms of baseline clinical data(all P>0.05),left main lesion condition(P=1.000),left main calcification condition(P=0.249),and preoperative TIMI flow grading(P=1.000).In the comparison between observation group and the control group,intraoperative occurrence of no-reflow(3.3%vs.5.0%,P=1.000),hypotension(10.0%vs.8.3%,P=1.000),pericardial effusion(3.3%vs.0%,P=0.333),the percentage of intravascular ultrasound(IVUS)use(86.7%vs.90.0%,P=0.635),and the use of circulatory assist device(P=0.699),and the proportion of intraoperative coronary spinning(26.7%vs.21.7%,P=0.597)were all similar between the two groups.The median follow-up time was 14.50(11.83,15.85)months,and the differences in the incidence of major adverse cardiovascular events(MACE)such as recurrent angina,acute myocardial infarction,rebleeding,readmission for heart failure,and cardiac death(31.0%vs.32.1%,P=1.000)were not statistically significant between the observation group and the control group. Conclusions:PCI revascularization may be a viable approach for elderly patients with complex LM lesions with multiple underlying disease,and combined right coronary artery CTO,intolerance and reluctance to CABG.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Objective To explore the potential targets of triclosan in the treatment of nonalcoholic fatty liver disease(NAFLD) and to provide new clues for the future research on the application of triclosan. Methods The targets of triclosan and NAFLD were obtained via network pharmacology.The protein-protein interaction network was constructed with the common targets shared by triclosan and NAFLD.The affinity of triclosan to targets was verified through molecular docking.Gene ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment were carried out to analyze the key targets and the potential mechanism of action.NAFLD model was established by feeding male C57BL/6J mice with high-fat diet for 12 weeks.The mice were randomly assigned into a model group and a triclosan group [400 mg/(kg·d),gavage once a day for 8 weeks].The hematoxylin-eosin(HE) staining was used for observation of the pathological changes and oil red O staining for observation of fat deposition in mouse liver.Western blotting was employed to detect the protein level of peroxisome proliferator-activated receptor alpha(PPARα) in the liver tissue. Results Triclosan and NAFLD had 34 common targets,19 of which may be the potential targets for the treatment,including albumin(ALB),PPARα,mitogen-activated protein kinase 8(MAPK8),and fatty acid synthase.Molecular docking predicted that ALB,PPARα,and MAPK8 had good binding ability to triclosan.KEGG pathway enrichment showcased that the targets were mainly enriched in peroxisome proliferator-activated receptor signaling pathway,in which ALB and MAPK8 were not involved.Triclosan alleviated the balloon-like change and lipid droplet vacuole,decreased the lipid droplet area,and up-regulated the expression level of PPARα in mouse liver tissue. Conclusion PPARα is a key target of triclosan in the treatment of NAFLD,which may be involved in fatty acid oxidation through the peroxisome proliferator activated receptor signaling pathway.

Dendrobium nobile Lindl. alkaloids (DNLA) promote the apoptosis of breast cancer and colon cancer cells, but whether they affect the malignant biological behavior of cervical cancer cells is unknown. Herein we explored the effects and possible mechanisms of DNLA on the proliferation, apoptosis, migration and invasion of cervical cancer SiHa cells. SiHa cells were transfected with si-NC, siKCNQ1OT1, miR-NC, miR-487a-3p mimics, pcDNA-NC or pcDNA-KCNQ1OT1. Different doses (15, 30, 60 ng/mL) of DNLA were applied. The CCK-8 method was used to detect cell proliferation; Tran-swell was used to detect cell migration and invasion; flow cytometry was used to detect cell apoptosis; Western blotting was used to detect the expression of MMP2, MMP9 and Cleaved-Caspase-3 genes at the protein level; RT-qPCR was used to detect the expression of KCNQ1OT1 and miR-487a-3p. The dual luciferase reporter gene experiment verified the regulatory relationship between KCNQ1OT1 and miR-487a-3p. The results showed that different doses (15, 30, 60 ng/mL) of DNLA reduced the absorbance value, migration number, invasion number, the protein level of MMP2 and MMP9, reduced the expression of KCNQ1OT1, and increased the apoptosis rate, the abundance of Cleaved-Caspase-3 and the expression of miR-487a-3p (P<0. 05). Low expression of KCNQ1OT1 or high expression of miR-487a-3p reduced the absorbance value, migration number, invasion number, and the protein level of MMP2 and MMP9, but increased the apoptosis rate and the abundance of Cleaved-Caspase-3 (P<0. 05). KCNQ1OT1 negatively regulated the expression of miR-487a-3p. The effects of high expression of KCNQ1OT1 on the proliferation, apoptosis, migration and invasion of SiHa cells were opposite to that of low expression of KCNQ1OT1, and high expression of KCNQ1OT1 reduced the effects of 60 ng/mL DNLA on the proliferation, apoptosis, migration and invasion of SiHa cells. In summary, DNLA may reduce the proliferation, migration and invasion of cervical cancer SiHa cells and promote SiHa cell apoptosis by regulating the KCNQ1OT1/miR-487a-3p axis.
