Dysfunction of the interoceptive system is recognized as an important component of clinical symptoms, including anxiety, depression, psychosis, and other mental disorders. Non-invasive neuromodulation is an emerging clinical intervention approach, and over the past decade, research on non-invasive neuromodulation aimed at regulating interoception has rapidly developed. This review first outlines the pathways of interoceptive signals and assessment methods, then summarizes the interoceptive abnormalities in psychiatric disorders and current studies for non-invasive neuromodulation targeting interoception, including intervention modes, target sites, interoceptive measures, and potential neurobiological mechanisms. Finally, we discuss significant research challenges and future directions.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

Opioid analgesics are currently known as the best analgesics. However， toxicity and side effects such as constipation， tolerance and addiction severely limit their clinical application. With the in-depth understanding of the signal transduction mechanism of opioid receptors and the continuous advancement of drug design technology， researchers have managed to develop many promising new methods to get low-toxic and more efficient opioid analgesics， which are different from the traditional morphine skeleton structure modifications. This article focuses on three new research strategies of G-protein biased activation，“ one drug-multiple targets” and peripheral activation. The basic principles of relative separation of analgesic activity and adverse drug reaction by each strategy are introduced， and the latest research progress of representative drugs is briefly reviewed. Among them， the recently approved novel opioid analgesics oliceridine and tegileridine are G-protein biased μ-opioid receptor agonists， Cebranopadol is a typical “one drug-multiple targets” analgesic， and NFEPP is a representative drug of peripheral opioid receptor agonists. The above several strategies complement each other and provide reference for the development of new opioid analgesic drugs.

Objective To examine the precise function of influenza A virus target genes(IATGs)in malignancy. Methods Using multi-omics data from the TCGA and TCPA datasets,33 tumor types were evaluated for IATGs.IATG expression in cancer cells was analyzed using transcriptome analysis.Copy number variation(CNV)was assessed using GISTICS 2.0.Spearman's analysis was used to correlate mRNA expression with methylation levels.GSEA was used for the enrichment analysis.Pearson's correlation analysis was used to examine the association between IATG mRNA expression and IC50.The ImmuCellAI algorithm was used to calculate the infiltration scores of 24 immune cell types. Results In 13 solid tumors,IATG mRNA levels were atypically expressed.Except for UCS,UVM,KICH,PCPG,THCA,CHOL,LAMI,and MESO,most cancers contained somatic IATG mutations.The main types of CNVs in IATGs are heterozygous amplifications and deletions.In most tumors,IATG mRNA expression is adversely associated with methylation.RT-PCR demonstrated that EGFR,ANXA5,CACNA1C,CD209,UVRAG were upregulated and CLEC4M was downregulated in KIRC cell lines,consistent with the TCGA and GTEx data. Conclusion Genomic changes and clinical characteristics of IATGs were identified,which may offer fresh perspectives linking the influenza A virus to cancer.

The standardized workflow of computer-aided static guided implant surgery includes preoperative exami-nation,data acquisition,guide design,guide fabrication and surgery.Errors may occur at each step,leading to irrevers-ible cumulative effects and thus impacting the accuracy of implant placement.However,clinicians tend to focus on fac-tors causing errors in surgical operations,ignoring the possibility of irreversible errors in nonstandard guided surgery.Based on the clinical practice of domestic experts and research progress at home and abroad,this paper summarizes the sources of errors in guided implant surgery from the perspectives of preoperative inspection,data collection,guide de-signing and manufacturing and describes strategies to resolve errors so as to gain expert consensus.Consensus recom-mendation:1.Preoperative considerations:the appropriate implant guide type should be selected according to the pa-tient's oral condition before surgery,and a retaining screw-assisted support guide should be selected if necessary.2.Da-ta acquisition should be standardized as much as possible,including beam CT and extraoral scanning.CBCT performed with the patient's head fixed and with a small field of view is recommended.For patients with metal prostheses inside the mouth,a registration marker guide should be used,and the ambient temperature and light of the external oral scan-ner should be reasonably controlled.3.Optimization of computer-aided design:it is recommended to select a handle-guided planting system and a closed metal sleeve and to register images by overlapping markers.Properly designing the retaining screws,extending the support structure of the guide plate and increasing the length of the guide section are methods to feasibly reduce the incidence of surgical errors.4.Improving computer-aided production:it is also crucial to set the best printing parameters according to different printing technologies and to choose the most appropriate postpro-cessing procedures.

Objective To investigate the key genes associated with ferroptosis in peri-implantitis and explore the potential mecha-nisms regulating peri-implantitis.Methods Several datasets were obtained from the GEO database.Differential expressed genes were screened,and GO and KEGG analyses were performed.A PPI network was constructed using the STRING website.Key genes were val-idated using a test set,and the diagnostic value of key genes was determined.The content and proportion of 22 immune cells in peri-im-plantitis tissues were obtained through immune infiltration analysis.Key genes were validated by qRT-PCR and Western Blot(WB).Results There were 1 138 differential genes between peri-implantitis tissues and normal gingival tissues,of which 29 were related to ferroptosis.The gene expression in peri-implantitis tissues mainly involved processes such as immune response activation.Five key genes in the ferroptosis-related differential genes,namely SOX2,GJA1,IL1B,GPX2 and CHAC1,were differentially expressed in peri-implantitis tissues and had high diagnostic value.Immune infiltration analysis showed significant changes in immune cells such as memory B cells and plasma cells in peri-implantitis tissues.qRT-PCR and WB confirmed significant differential expression of mRNA and the protein transcribed by key genes.Conclusion Differential genes between peri-implantitis and ferroptosis are screened using bioinformatics analysis and biological validation,providing new insights into the study on peri-implantitis.

Objective To explore the effect of personality characteristics on the facial esthetic satisfaction of edentulous patients,in order to provide reference for improving esthetic satisfaction after complete denture restoration.Methods Twenty-two edentulous sub-jects were randomly selected.Before complete denture treatment,the emotional stability of patients was assessed by Eysenck personality questionnaire N scale score(EPQ-N).Before and three months after treatment,patients completed the orofacial esthetic questionnaire,and 3D stereophotogrammetry was performed to evaluate the changes in facial appearance.In addition,multiple linear regression model was established by using N scale score,changes in facial appearance and facial esthetic satisfaction score.Results After complete denture treatment,the difference in the ratio of the middle and lower parts of the face between patients and the normal group was re-duced by(3.85±2.63)%,and the difference of the nasolabial angle between patients and the normal group was reduced by(6.66°±5.39°).The multiple linear regression model showed that N scale score and changes of the differencein the facial proportion between edentulous subjects and normal population were influencing factors of patients'esthetic satisfaction on the facial appearance,and the N scale score and changes of the difference inthe nasolabial anglebetween patients and normal population were influencing factors of the patients'aesthetic satisfaction on the facial profile.Moreover,the effect of two independent variables(N scale score and facial soft tissue change)on the aesthetic satisfaction of facial appearance and facial profile was statistically significant(P＜0.001).Furthermore,when the N score increased,the patients'aesthetic satisfaction on the facial appearance and facial profile decreased(B＜0).Conclusion Personality can affect the aesthetic satisfaction of edentulous patients.Consequently,we should take reasonable measures for patients with different personality in the process of complete denture restoration,so as to achieve the goal of improving patients'aesthetic satisfaction.

Objective:To explore the protective effect of sivelestat (SV) against sepsis-induced acute kidney injury (AKI) and its molecular mechanism.Methods:According to the random number table method, 64 male Wistar rats were divided into sham operation group (Sham group), sepsis due to cecal ligation and puncture group (CLP group), low dose of SV treatment group (SL group, 50 mg/kg SV was injected into the tail vein at 12 hours and 24 hours after CLP), and high dose of SV treatment group (SH group, 100 mg/kg SV was injected into the tail vein at 12 hours and 24 hours after CLP), with 16 rats in each group. 48 hours after CLP, the 48-hour survival of rats were recorded, all rats were sacrificed and samples were harvested. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of kidney injury molecule-1 (KIM-1), interleukins (IL-1β, IL-6), tumor necrosis factor-α (TNF-α) and neutrophil elastase (NE). Hematoxylin-eosin (HE) staining was used to observe histopathological changes and assess renal tubule injury score. Masson staining was used to detect the collagen volume fraction (CVF) of kidney tissue. Western blotting was used to detect the protein expressions of phosphatidylinositol 3-kinase (PI3K), phosphorylation PI3K (p-PI3K), protein kinase B (AKT), phosphorylation AKT (p-AKT), nuclear factor-κB p65 (NF-κB p65) and NE. The protein expressions of p-PI3K, p-AKT, NF-κB p65 were detected by immunohistochemistry.Results:Compared with Sham group, the 48-hour survival rate of CLP group was significantly reduced. Histopathological results showed that large tubular epithelial cells and brush margins were shed, tubular casts were formed, some tubular atrophy, glomerular hyperemia, renal interstitial inflammatory cell infiltration and increased renal tubular injury score. Renal interstitial fibrosis was obvious and CVF increased. The levels of KIM-1, IL-1β, IL-6, TNF-α and NE in serum were significantly elevated in the CLP group. The proteins expression of inflammatory pathway-related p-PI3K/PI3K, p-AKT/AKT, NF-κB p65 and NE were significantly increased in kidney tissue. It suggested that septic rats had renal injury and the PI3K/AKT inflammatory pathway was activated. Compared with CLP group, there was no significant difference in 48-hour survival in SL group and SH group (68.75%, 75.00% vs. 56.25%, both P > 0.05), but kidney injury was significantly relieved. Specifically: renal tubular injury score and CVF significantly decreased [tubular injury score: 2 (1, 2), 1 (1, 1) vs. 2 (2, 3); CVF: (22.36±0.86)%, (18.74±1.05)% vs. (58.38±0.79)%, all P < 0.05]; the serum levels of KIM-1, IL-1β, IL-6, TNF-α and NE also decreased significantly [KIM-1 (ng/L): 145.03±8.88, 117.58±7.02 vs. 158.22±12.00; IL-1β (ng/L): 108.32±9.00, 92.98±8.06 vs. 133.78±8.48; IL-6 (ng/L): 124.33±10.11, 115.42±8.17 vs. 165.19±5.70; TNF-α (ng/L): 321.56±19.29, 289.68±21.57 vs. 424.88±22.76, NE (mol/L): 93.84±9.14, 75.01±10.56 vs. 113.45±6.39, all P < 0.05]; the proteins expression of inflammatory pathway-related p-PI3K/PI3K, p-AKT/AKT, NF-κB p65 and NE were significantly decreased (p-PI3K/PI3K: 0.93±0.06, 0.67±0.04 vs. 1.27±0.08; p-AKT/AKT: 0.78±0.09, 0.47±0.05 vs. 0.96±0.12; NF-κB p65/GAPDH: 1.43±0.13, 0.85±0.08 vs. 1.88±0.17; NE/GAPDH: 1.45±0.06, 0.91±0.04 vs. 1.71±0.08, all P < 0.05), the positive expressions of p-PI3K, p-AKT and NF-κB p65 in kidney tissue were decreased [p-PI3K positive expression area: (13.36±1.84)%, (8.03±1.12)% vs. (21.56±1.20)%; p-AKT positive expression area: (21.57±0.91)%, (15.21±2.76)% vs. (30.81±2.12)%; NF-κB p65 positive expression area: (25.17±1.38)%, (17.07±2.11)% vs. (37.85±2.50)%, all P < 0.05]. Serum inflammatory factor level, and PI3K/AKT pathway related protein, NF-κB p65, NE protein expression level and p-PI3K, p-AKT, NF-κB p65 positive area and other indicators in renal tissue in SH group were further lower than those in SL group (all P < 0.05). Conclusions:SV can ameliorate sepsis-induced AKI. The mechanism may be related to the inhibition of PI3K/AKT pathway, and high dose of SV has better efficacy.

Cancer-related fatigue (CRF) is a symptom associated with cancer and cancer treatment. The incidence of CRF during radiotherapy is extremely high and severely affects the quality of life and treatment compliance of patients. Although more and more studies on CRF have been carried out, the pathogenesis of CRF caused by radiotherapy is still not well understood, and systemic interventions remain to be improved. In this article, the pathogenesis, influencing factors, and interventions of CRF caused by radiotherapy were reviewed, aiming to provide reference for optimizing treatment options in clinical practice.

Objective To evaluate the risk of occupational noise-induced hearing loss in workers in a metal tool manufacturing enterprise, and to carry out risk classification and risk management. Methods A total of 91 male noise-exposed workers from a metal tool manufacturing enterprise in Hebei Province were selected as the research subjects using the convenience sampling method. The work site survey on occupational health and the measurement on individual noise exposure level were carried out. The ISO 1999：2013 (E) Acoustics-Estimation of Noise-Induced Hearing Loss was used to predict the risk of high frequency hearing loss (HFHL) and occupational noise-induced deafness (ONID). The risk classification and risk management were conducted using the WS/T 754-2016 Guideline for Risk Management of Occupational Noise Hazard (hereinafter referred to as WS/T 754-2016). Results The individual noise exposure intensity of workers in the six work sites of the enterprise, including blade workers, sheet punching workers, roller forging workers (hoe), hole punching workers, roller forging workers(shovels), and carpenters, exceeded the national occupational exposure limit, with the maximum volume of 91.2-104.1 dB(A). Among these workers, the positions of blade workers, sheet punching workers, and roller forging workers (hoe) were identified as critical control points for noise hazards in the enterprise. The detection rates of HFHL and ONID were 24.2% and 8.8%, respectively. The risk prediction results showed that, based on the actual noise exposure time and age of the study subjects, the risk of HFHL and ONID ranged from 1.7%-48.8% and 0.0%-29.5%, respectively. The risks of HFHL caused solely by occupational noise exposure when working up to 50.0, 55.0, and 60.0 years of age were 11.4% to 64.7%, 16.4% to 65.1%, and 17.2% to 59.4%, respectively. The risks of ONID caused solely by occupational noise exposure were 0.0% to 45.5%, 4.2% to 51.7%, and 5.9% to 57.4%, respectively. Except for the blade workers, the predicted median of potential noise-induced permanent threshold shifts (NIPTS) in the other five positions were lower than the actual values of NIPTS, with the difference ranging from 3.0-28.3 dB, and 73.3% of them underestimated by 10.0 dB or more. Conclusion The outcome of noise exposure on the hearing of workers in this enterprise are severe. Risk management should be conducted according to the WS/T 755-2016.
