Objective To investigate the role of Ezrin and its phosphorylation(p-Ezrin)in the modulation of rat pulmonary microvascular endothelial cell(PMVEC)injury induced by tumor necrosis factor-α(TNF-α)and the impact of Rac 1. Methods Cultured PMVECs of Sprague-Dawley(SD)rats were randomly divided into time-dependent injury group induced by TNF-αand intervention group in which cells were pretreated with Rac 1 inhibitor (NSC 23766).①In the time-dependent injury group, Western Blot was used to detect the expression of Ezrin and p-Ezrin after 10μg/L TNF-αstimulation for 0,0.25,0.5,1,3,6,12,24 hours.②In the intervention group,after pre-treatment with 200μmol/L NSC 23766 for 0.5 h,PMVECs were treated with 10μg/L TNF-α,and the expression of p-Ezrin was detected by Western Blot after 3 hours. Besides these groups,there were control(1% fetal bovine serum simulation),single NSC 23766 or TNF-α simulation groups. Results ① Few Ezrin expression was found in PMVEC,and TNF-α could not affect Ezrin expression. p-Ezrin protein expression(p-Ezrin/Ezrin,gray scale) of PMVECs at 0 hour after TNF-αstimulation was 0.21±0.03,and elevated at 0.25 hour(0.53±0.19),peaked at 3 hours(1.68±0.30),then it was gradually lowered,but it remained at higher level at 24 hours(0.87±0.18)with significant difference(F=62.200,P=0.000). It demonstrated that TNF-αcould increase Ezrin phosphorylation in a time-dependent manner.②Compared with blank control group,in single NSC 23766 or TNF-αsimulation group, p-Ezrin expression was induced(TNF-αgroup:0.92±0.12 vs. 0.68±0.16,t=-2.864,P=0.020;NSC 23766 group:1.33±0.24 vs. 0.68±0.16,t=-5.429,P=0.000. When NSC 23766 was pre-treated with PMVECs,the expression of p-Ezrin was significantly increased compared with that in single TNF-αsimulation group(2.14±0.18 vs. 0.92±0.12,t=-14.670,P=0.000)with significant difference(F=73.810,P=0.000). Conclusion Ezrin proteins are phosphorylated by TNF-α. Rac 1 signaling pathway inhibition plays an important role in TNF-α-induced injury by up-regulation of p-Ezrin in PMVECs.

Hepatitis B virus (HBV) infection can cause a series of severe liver diseases such as chronic hepatitis B, liver cirrhosis and hepatocellular carcinoma, remaining one of most serious worldwide public health problems. Autophagy is a conserved lysosome-dependent degradation pathway in eukaryotic cells and plays a critical role in host innate immune response. Multiple processes in the life cycle of HBV, including viral replication, maturation and secretion, are closely related to autophagy. Autophagy can regulate the assemble, envelopment and secretion of HBV in human hepatocytes and participate in innate and adaptive immune responses to clear HBV. HBV induces strong autophagy in human hepatocytes and escapes autophagic degradation through certain mechanisms. This review summarized the progress in autophagy and autophagic degradation regulated by HBV infection, hoping to provide a theoretical reference for further understanding the mechanism of autophagy regulated by HBV infection and developing novel strategies for anti-HBV therapy.

ObjectiveTo analyze the hotspots and development of researches on animal-assisted intervention in the past ten years. MethodsThe researches on animal-assisted intervention from 2011 to 2021 were retrieved from the Web of Science core database, and analyzed the countries/regions, institutions, authors, cited journals, cited literature and keywords using CiteSpace. ResultsA total of 607 researches were included. The researches increased with years, while United States (230), Italy (65) and the United Kingdom (45) were the top three in the number of publications; Purdue University published the most researches (20); and Santaniello A, etc. were the high-producing authors. The key nodes of literature were mainly systematic reviews and randomized controlled trials. Animal-assisted therapy and dogs were high-frequency keywords, with 20 keywords of high centrality and 16 keywords of strongest bursting. Hotspots focused on Alzheimer's disease, depression, children, autism. Disorder and occupational therapy might be the new topics in the future. ConclusionThe animal-assisted intervention has been mainly used as a healthcare in psychology, and may be an approach of occupational therapy.

Objective To explore the effects of different acupoints,different target organs,and different interventions on acupoint efficacy based on ACU&MOX-DATA platform;To illustrate and visualize whether the above factors have the characteristics of"specific effect"or"common effect"of acupoint efficacy.Methods The multi-source heterogeneous data were integrated from the original omics data and public omics data.After standardization,differential gene analysis,disease pathology network analysis,and enrichment analysis were performed using Batch Search and Stimulation Mode modules in ACU&MOX-DATA platform under the conditions of different acupoints,different target organs,and different interventions.Results Under the same disease state and the same intervention,there were differences in effects among different acupoints;under the same disease state,the same acupoint and intervention,the responses produced by different target organs were not completely consistent;under the same disease state and acupoint,there were differences in effects among different intervention measures.Conclusion Based on the analysis of ACU&MOX-DATA platform,it is preliminary clear that acupoints,target organs,and interventions are the key factors affecting acupoint efficacy.Meanwhile,the above results have indicated that there are specific or common regulatory characteristics of acupoint efficacy.Applying ACU&MOX-DATA platform to analyze and visualize the critical scientific problems in the field of acupuncture and moxibustion can provide references for deepening acupoint cognition,guiding clinical acupoint selection,and improving clinical efficacy.
