Objective: To explore the effects of different concentrations of glucose solution on the survival of Aedes albopictus and Culex pipiens pallens larvae, the attraction to mosquitoes and egg-laying behaviors, so as to provide the reference for developing mosquito control technology based on sugar bait. Methods: White porcelain bowls were filled with 100 mL of 3%, 5%, 8%, 10% and 15% glucose solutions. Ten of fourth instar larvae of Aedes albopictus or Culex pipiens pallens were added to each bowl, and the survival of larvae was recorded after 2, 4, 6, 24, 48 and 72 hours. Egg-laying cups containing 5%, 8% and 15% glucose solution were put in mosquito cages containing fully blooded female mosquitoes of Aedes albopictus and Culex pipiens pallens (50 mosquitoes each), and the total number of eggs laid in 72 hours was observed. The analogous site room was filled with fully blooded and starved female mosquitoes of Aedes albopictus and Culex pipiens pallens (100 mosquitoes each), and simple mosquito control buckets containing 5% and 8% glucose solution and black sticky insect plates. The number of mosquitoes and eggs was observed after 6 days. All the above experiments were repeated 3 times using dechlorinated water as the control. Results: The 72 hour corrected mortality rates of Aedes albopictus and Culex pipiens pallens larvae gradually increased with the increase of glucose concentration. The glucose solution with 5% and higher concentrations was not suitable for mosquito larvae to survive. The attraction of egg-laying behaviors to Aedes albopictus and Culex pipiens pallens gradually decreased with the increase of glucose concentration. The effects were similar between 5% and 8% glucose solution, with the averages of 686.67 and 682.33 eggs for Aedes albopictus, and 3.00 and 2.33 egg rafts for Culex pipiens pallens. In analogous site room, there were 93.33, 105.00 and 130.33 adult mosquitoes captured on average in the control group, 5% and 8% glucose solution groups, respectively, with 8% glucose solution group more attractive to adult mosquitoes than the control group (F=3.283, P=0.030); there were 70.33, 55.33 and 63.00 Aedes albopictus eggs (eggs counts+larvae counts) on average, respectively, with statistically significant differences among the three groups (H=6.761, P=0.034). Conclusion Glucose solution with concentration of 5% or higher can effectively inhibit the survival of Aedes albopictus and Culex pipiens pallens larvae, and attractive to adult mosquitoes and egg-laying behavoirs.

BACKGROUND:The application of orthodontic force triggers autophagy in the periodontal tissue via diverse signaling pathways,augmenting or attenuating the activity of relevant cell types such as periodontal ligament cells,osteocytes,osteoclasts,and osteoblasts,thus facilitating the process of periodontal remodeling. OBJECTIVE:To review the research progress in orthodontic force mediated autophagy in periodontal tissue and its impact on orthodontic tooth movement. METHODS:The PubMed,Web of Science,China Biology Medicine disc and CNKI were searched for literature published from 2010 to 2023 to summarize the progress in orthodontics-related autophagy.And 76 papers were finally included in the analysis and discussion. RESULTS AND CONCLUSION:Orthodontic force can trigger a series of biochemical signal changes through periodontal mechanical receptors and aseptic inflammation they cause,leading to autophagy in periodontal tissue.Subsequently,autophagy generates corresponding feedback through cascaded amplified signaling pathways such as Phosphoinositide 3-kinase/protein kinase B,Hippo,and mitogen-activated protein kinase pathways,promoting periodontal tissue remodeling and ultimately achieving tooth movement and stability.Orthodontic force-induced autophagy can differentially regulate bone resorption on the tooth pressure side and bone formation on the tension side.Related targets have good prospects in the clinical application of orthodontic treatment.Orthodontics and autophagy have complex mechanisms.However,existing research has only focused on exploring the role of autophagy in orthodontic tooth movement.Further exploration is needed to investigate the mutual regulatory effects between autophagy and orthodontic tooth movement,as well as the interactions between upstream mechanical receptors and signaling pathways involved in related pathways.

AIM:To explore the effects of CD38 on lysosome reformation and cholesterol efflux in macro-phages.METHODS:Bone marrow-derived macrophages from low-density lipoprotein(LDL)receptor knockout(LDLr-/-)mice were cultured as cell model.Live cell imaging system was applied to evaluate the effect of nicotinic acid adenine di-nucleotide phosphate(NAADP)on lysosome number.ELISA was conducted to measure NAADP level in macrophages.After the cells were treated with nicotinic acid(NA),RT-qPCR was conducted to detect CD38 mRNA expression,and Western blot was conducted to observe CD38 protein expression and phosphorylated transcription factor EB(TFEB)level.Laser scanning confocal microscopy was applied to evaluate the influence of CD38/NAADP signaling on lysosome number and cholesterol egression.RESULTS:NAADP remarkably increased lysosome number(P<0.05),and this effect was significantly inhibited by NAADP antagonist NED-19,Ca2+ chelator BAPTA,and calcineurin inhibitor CsA(P<0.05).CD38 markedly enhanced NAADP synthesis in macrophages(P<0.05).NAADP synthetic substrate NA prominently ele-vated the expression of CD38 mRNA and protein(P<0.05).NA significantly decreased the phosphorylated TFEB level;this effect was also attenuated by NED-19,BAPTA and CsA(P<0.05).Disrupting CD38/NAADP signaling pathway markedly inhibited NA-induced enhancement of lysosome number,lysosomal free cholesterol and cytosol cholesterol ester efflux in macrophages(P<0.05).NA-induced enhancement of lysosome number,lysosomal free cholesterol and cytosol cholesterol ester efflux abolished in LDLr/CD38 DKO macrophages(P<0.05),whereas these effects induced by NA were recovered after CD38 gene rescue.CONCLUSION:CD38 triggers lysosome reformation via TFEB and consequently pro-motes the efflux of lysosomal free cholesterol and cytosol cholesterol ester.

Abstract Dry eye disease is a chronic ocular surface inflammatory disease caused by abnormal tear quality or quantity and decreased tear film stability due to various reasons, and often accompanied by ocular discomfort such as itching, dryness, foreign body sensation, and visual dysfunction, which can seriously affect the patient′s quality of life and visual quality if not intervened in time. With the change of social lifestyles, the increase of environmental pollution and the trend of population aging, dry eye disease has become the most common ocular surface disease besides refractive error. Currently, dry eye disease is widely recognized as a non-infectious immune-related inflammatory disease, but the signaling pathways involved in dry eye disease are poorly understood. Whether dry eye disease is caused by excessive tear evaporation, insufficient tear production, or mucin deficiency, the ocular surface tissues(cornea/conjunctiva) inevitably undergo pathological processes such as aberrant proliferation, squamous epithelial hyperplasia, initiation of corneal damage repair mechanisms, and reduction in the number of conjunctival goblet cells, whereas the Wnt/β-catenin pathway is known to have a wide range of biological functions and plays an important role in cell proliferation, differentiation, and stemness maintenance. Therefore, this review describes the pathogenesis and potential experimental therapeutic options of the Wnt/β-catenin signaling pathway in dry eye disease from this perspective, aiming to provide new targets for the treatment of dry eye disease and achieve the goal of controlling the disease progression from the root.

Objective To explore the sufentanil by adjusting the adenosine monosodium phosphate activa-ted protein kinase(AMPK)/thioredoxin interacting proteins(TXNIP)/nucleotide-binding oligomerization do-main-like receptor protein 3(NLRP3)signaling pathways of the alveolar epithelial cells induced by lipopo-lysaccharide to the dead.Methods Human alveolar epithelial type Ⅱ cell(AECⅡ)were cultured to logarith-mic phase.Then they were divided into control group(normal glucose culture),lipopolysaccharide group(li-popolysaccharide induced injury by 50 μg/mL),low concentration sufentanil group(20 μmol/L),high concen-tration sufentanil group(40 μmol/L),high concentration sufentanil(40 μmol/L)+AMPK-IN-3 group(50μmol/L AMPK inhibitors).MTT assay was used to detect cell proliferation.Pyroptosis was detected by Ho-echst 33342 and propidium iodide(PI)double staining.The levels of interleukin(IL)-1β,IL-18 and tumor nec-rosis factor-α(TNF-α)in cell supernatant were detected by enzyme-linked immunosorbent assay.Quantitative real-time PCR was used to detect the mRNA expression of focal death related factors cysteinyl proteinase-1(Caspase-1),apoptosis-associated speck-like protein(ASC),and gasdermin D(GSDMD).The protein expres-sion of AMPK,phosphorylated adenosine monosodium phosphate activated protein kinase(p-AMPK),TXNIP and NLRP3 were detected by Western blot.Results Compared with the control group,the survival rate of AEC Ⅱ cells in the lipopolysaccharide group decreased,the number of PI+positive cells increased,the release of inflammatory factors IL-1β,IL-18 and TNF-α increased,the expression of Caspase-1,ASC and GSDMD mR-NA increased,the expression of p-AMPK/AMPK decreased,and the expression of TXNIP and NLRP3 in-creased(P＜0.05).Compared with the lipopolysaccharide group,the survival rate of AEC Ⅱ cells in the low concentration sufentanil group and the high concentration sufentanil group increased,PI+positive cells de-creased,the release of inflammatory factors IL-1β,IL-18 and TNF-α decreased,the expression of Caspase-1,ASC and GSDMD mRNA decreased,the expression of p-AMPK/AMPK increased,and the expression of TX-NIP and NLRP3 decreased(P＜0.05).Compared with the high concentration sufentanil group,the survival rate of AEC Ⅱ cells in the high concentration sufentanil+AMPK-IN-3 group decreased,the number of PI+positive cells increased,the release of inflammatory factors IL-1β,IL-18 and TNF-α increased,the expression of Caspase-1,ASC and GSDMD mRNA increased,the expression of p-AMPK/AMPK decreased,and the ex-pression of TXNIP and NLRP3 increased(P＜0.05).Conclusion Sufentanil may improve lipopolysaccharide induced alveolar epithelial cell pyroptosis by regulating AMPK/TXNIP/NLRP3 signaling pathway.

As a severe clinical manifestation of nonalcoholic fatty liver disease， nonalcoholic steatohepatitis （NASH） is characterized by lipid deposition and inflammatory damage in the liver. At present， clinical medications for NASH are still in the exploratory phase， and it is urgent to make progress. Recent studies have shown that the pathogenesis of NASH is associated with circadian rhythm disorders in the liver， with the specific manifestation of dysregulated expression of liver clock genes such as BMAL1， which increases hepatic lipogenesis， reduces fatty acid oxidation， and activates pro-inflammatory factors. Therefore， improving circadian rhythm of the liver and regulating the expression of liver clock genes are feasible strategies for the prevention and treatment of NASH. Currently， some medications for NASH via activating the proteins encoded by clock genes have been applied in animal experiments， for example， the REVERB full-agonist SR9009 can inhibit the development of liver inflammation， which confirms the possibility of NASH treatment by targeting the proteins encoded by clock genes. This article summarizes the role of hepatic clock genes in regulating lipid metabolism and the development and progression of inflammation in the liver and elaborates on the recent advances in medications targeting clock genes and the proteins encoded by clock genes， in order to provide new targets for the treatment of NASH.
