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.

Objective:To analyze the efficacy of unilateral arytenoid chondroplasty combined with minimally invasive mucosal flap plasty in the management bilateral vocal cord paralysis.Methods:A total of 66 patients with bilateral vocal cord paralysis hospitalized in the First Hospital of Sun Yat-sen University from January 2018 to December 2023 were retrospectively analyzed, among whom there were 8 males and 58 females, with ages ranging from 35 to 86 years old(mean age (57.8±11.6) years). All patients underwent suspension laryngoscopic CO 2 laser unilateral arytenoid chondroplasty and mucosal flap under general anesthesia. Postoperative follow-up period extended from 6 months to 6 years, with a median duration of 28 months. The study compared the degree of dyspnea and voice quality (subjective and objective evaluation) of the patients pre- and post-operatively, and analyzed the clinical differences between patients with and without preoperative or intraoperative tracheotomy, the extubation rate of tracheotomized patients, the recurrence rate, and the complication rate. Continuous variables conforming to normal distribution were tested by t-test and categorical variables by χ2 test,the Wilcoxon rank-sum test was used to analyze the improvement in dyspnea before and after surgery. Results:Compared with the preoperative period, 59 patients showed improvement in postoperative dyspnea ( U=161.5, P<0.01); there was no significant difference in voice disorder index 10, subjective auditory-perceptual assessment, and maximal vocalization time ( P>0.05), all of which remained within the relative normal range. Tracheotomy was performed in 32 out of 66 patients, with predominantly degree Ⅲ- dyspnea (46.9%, 15/32), including 26 patients with preoperative tracheotomy and 6 patients with intraoperative tracheotomy. Among the 34 patients who did not undergo tracheotomy, the majority presented with degree Ⅱ-dyspnea (82.4%, 28/34). All patients achieved successful extubation following surgery, with a mean median time to extubation of 1 month. Conclusions:The combination of unilateral arytenoid chondroplasty and minimally invasive mucosal flap plasty represents a refined and effective therapeutic approach for bilateral vocal cord paralysis. This minimally invasive technique has the potential to reduce the rate of tracheotomy.

Objective To analyze the core functional component groups(CFCG)in Yinchenhao Decoction(YCHD)and their possible pathways for treating hepatic fibrosis based on network pharmacology.Methods PPI data were extracted from DisGeNET,Genecards,CMGRN and PTHGRN to construct a weighted network using Cytoscape 3.9.1.The data of the chemical components in YCHD were obtained from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),and the potential active components and targets were selected using PreADMET Web server and SwissTargetPrediction.A fusion model was constructed to obtain the functional effect space and evaluate the effective proteins to identify the CFCG followed by GO and KEGG pathway enrichment analyses for all the targets.In cultured human hepatic stellate cells(LX-2 cells),the cytotoxicity of different compounds in YCHD was tested using CCK-8 assay;the effects of these compounds on collagen α1(Col1a1)mRNA expression and the pathways in 20 ng/mL TGF-β1-stimulated cells were analyzed using RT-qPCR and Western blotting.Results A total of 1005 pathogenic genes,226 potential active components and 1529 potential targets in YCHD and 52 potential targets of CFCG were obtained.Benzyl acetate,vanillic acid,clorius,polydatin,lauric acid and ferulic acid were selected for CCK-8 verification,and they all showed minimal cytotoxicity below the concentration of 200 μmol/L.Clorius,polydatin,lauric acid and ferulic acid all effectively inhibited TGF-β1-induced LX-2 cell activation.At the concentration of 200 μmol/L,all these 4 components inhibited PI3K,p-PI3K,AKT,p-AKT,ERK,p-ERK,P38 MAPK and p-P38 MAPK expressions in TGF-β1-induced LX-2 cells.Conclusion The therapeutic effect of YCHD on hepatic fibrosis is probably mediated by its core functional components including benzyl acetate,vanillic acid,clorius,polydatin,lauric acid and ferulic acid,which inhibit the PI3K-AKT and MAPK pathways in hepatic stellate cells.

Objective:To evaluate the feasibility of PET automatic drug infusion system combined with power peripherally inserted central catheter (PICC) for 18F-FDG injection and PET/CT imaging. Methods:Fifty patients with malignant neoplasms who underwent 18F-FDG PET/CT imaging in Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine between December 2021 to July 2022 were prospectively enrolled. They were equally divided into power PICC group and peripheral venipuncture group. PET automatic drug infusion system was respectively connected with the pre-established channels of power PICC and peripheral venipuncture for 18F-FDG injection. Each patient underwent a routine PET/CT imaging at 1 h post-injection. The blood glucose, body weight, prescription dose and injection dose were recorded, and SUV max in the liver and cavoatrial junction were measured in both groups. The independent-sample t test was performed to compare the differences between 2 groups. The power PICC tip positions after 18F-FDG injection in power PICC group were observed. Results:The liver SUV max in the power PICC group and peripheral group were 2.54±0.50 and 2.57±0.31 ( t=0.37, P=0.716), and the SUV max of cavoatrial junction in the 2 groups were 1.68±0.25 and 1.63±0.22 ( t=-0.78, P=0.441), respectively. No significant differences were found in blood glucose, body weight, prescription dose and injection dose between the 2 groups ( t values: 0.00-0.13, all P>0.05). The ratios of injection dose to prescription dose in the 2 groups were 0.998 3±0.007 3 and 0.997 6±0.016 5, respectively, indicating high injection accuracy of the injection methods. No obvious drug residue was displayed at the end of catheter, resulting in good imaging quality. All the tip positions after injection were between T5 and T8, in line with the standardization management of power PICC. Conclusion:PET automatic drug infusion system combined with power PICC can be safely used for 18F-FDG injection and PET/CT imaging with less injection puncture.
