Objective This study aimed to investigate the temporal and spatial changes in the expression of perios-tin during periodontal inflammation in mice.Methods A periodontitis model was constructed using silk thread ligation.Mice were randomly divided into five groups in-cluding control group,4-day ligation group,7-day liga-tion group,14-day ligation group,and self-healing group(thread removal for 14 days after 14-day ligation).Mi-cro-CT and histological staining were performed to char-acterize the dynamic changes in the mouse periodontal tissue in each group.RNAscope and immunohistochemical staining were used to analyze the pattern of changes in peri-ostin at various stages of periodontitis.The cell experiment was divided into three groups:control group,lipopolysac-charide(LPS)stimulation group(treated with LPS for 12 h),and LPS stimulation removal group(treated with LPS for 3 h followed by incubation with medium for 9 h).Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression of periostin,transforming growth factor-β1(TGF-β1),and matrix metalloproteinase 2(MMP2).Results Significant alveolar bone resorption was observed 7 days after ligation.With increasing duration of ligation,the damage to the mouse periodontal tissue was aggravated,which manifested as increased osteoclasts,widen-ing of the periodontal membrane space,and decreased alveolar bone height.Some degree of periodontal tissue repair was observed in the self-healing group.Periostin expression decreased at 4 and 7 days compared with the control group and increased at 14 days compared with 4 and 7 days.A significant recovery was found in the self-healing group.The qRT-PCR results showed that the expression of periostin and TGF-β1 in the LPS stimulation group decreased compared with that in the control group but significantly recovered in the LPS removal group.Conclusion Periostin expression in the PDL of mice showed a downward and upward trend with inflammation progression.The significant recovery of periostin expression after removing inflammatory stimuli may be related to TGF-β1,which is crucial to maintain the in-tegrity of the PDL.

Objective:To explore the current status of rumination in inpatients with metastatic prostate cancer (mPCa) under the disease coping mechanism, and analyzing its influencing factors.Methods:From March 2021 to December 2022, 267 mPCa inpatients at the Tenth People's Hospital of Tongji University were selected as the study subject using convenience sampling. The survey was conducted using the General Information Questionnaire, Chinese Version of Event Relate Rumination Inventory (C-ERI), Medical Coping Modes Questionnaire (MCMQ), International Prostate Symptom Score (IPSS), and Social Support Revalued Scale (SSRS), and the factors influencing the rumination in patients were analyzed.Results:This study collected 260 valid questionnaires, with an effective response rate of 97.4% (260/267). The total score of rumination in 260 mPCa patients was (31.08±6.46), with invasive rumination and purposeful rumination scores of (14.13±4.44) and (16.95±4.55), respectively. The initial prostate-specific antigen index, confrontation medical coping modes were the influencing factors of invasive rumination in mPCa patients ( P<0.05). The initial prostate-specific antigen index, course of disease, social support, and confrontation medical coping style were the influencing factors of purposeful rumination in mPCa patients ( P<0.05) . Conclusions:The rumination of mPCa patients is above the medium level, and is influenced by multiple factors under the disease coping mechanism. Clinical medical and nursing staff should combine the clinical situation and characteristics of mPCa patients, provide personalized interventions as early as possible, and assist patients in improving their positive cognitive processing abilities.

OBJECTIVES: Shelter hospital was an alternative way to provide large-scale medical isolation and treatment for people with mild coronavirus disease 2019 (COVID-19). Due to various reasons, patients admitted to the large shelter hospital was reported high level of psychological distress, so did the healthcare workers. This study aims to introduce a comprehensive and multifaceted psychosocial crisis intervention model. METHODS: The psychosocial crisis intervention model was provided to 200 patients and 240 healthcare workers in Wuhan Wuchang shelter hospital. Patient volunteers and organized peer support, client-centered culturally sensitive supportive care, timely delivery of scientific information about COVID-19 and its complications, mental health knowledge acquisition of non-psychiatric healthcare workers, group activities, counseling and education, virtualization of psychological intervention, consultation and liaison were exhibited respectively in the model. Pre-service survey was done in 38 patients and 49 healthcare workers using the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Patient Health Questionnaire 2-item (PHQ-2) scale, and the Primary Care PTSD screen for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (PC-PTSD-5). Forty-eight healthcare workers gave feedback after the intervention. RESULTS: The psychosocial crisis intervention model was successfully implemented by 10 mental health professionals and was well-accepted by both patients and healthcare workers in the shelter hospital. In pre-service survey, 15.8% of 38 patients were with anxiety, 55.3% were with stress, and 15.8% were with depression; 16.3% of 49 healthcare workers were with anxiety, 26.5% were with stress, and 22.4% were with depression. In post-service survey, 62.5% of 48 healthcare workers thought it was very practical, 37.5% thought more practical; 37.5% of them thought it was very helpful to relief anxiety and insomnia, and 27.1% thought much helpful; 37.5% of them thought it was very helpful to recognize patients with anxiety and insomnia, and 29.2% thought much helpful; 35.4% of them thought it was very helpful to deal with patients' anxiety and insomnia, and 37.5% thought much helpful. CONCLUSIONS Psychological crisis intervention is feasible, acceptable, and associated with positive outcomes. Future tastings of this model in larger population and different settings are warranted.

Objective:To compare the efficacy of endoscopic submucosal dissection (ESD) and surgery for circumferential superficial esophageal squamous cell neoplasm.Methods:A retrospective analysis was performed on 153 patients with superficial esophageal squamous cell neoplasm who underwent ESD or surgery at Cancer Hospital, Chinese Academy of Medical Sciences from November 2013 to October 2021. There were 116 cases in ESD group and 37 cases in the surgical group. The en block resection rate, complete resection rate, operation time, perioperative complication incidence, postoperative quality of life, postoperative disease-free survival and overall survival were compared.Results:In the ESD group, the en block resection rate was 100.0% (116/116) and the complete resection rate was 96.6% (112/116). The longitudinal diameter of lesion had no significant correlation with complications or complete resection rate ( P>0.05). The operation time of the ESD group was significantly shorter than that of the surgical group (175.1±52.2 min VS 266.7±88.2 min, t=-5.991, P<0.001). There was no significant difference in the incidence of perioperative complications between the ESD group and surgical group [5.2% (6/116) VS 8.1% (3/37), P=0.452]. According to EORTC-QLQ-C30 and EORTC-QLQ-OES18, emotional function ( P=0.008),cognitive function ( P=0.013) and the total health level ( P<0.001) of the ESD group were significantly higher than those in the surgical group. Fatigue ( P=0.002), pain ( P<0.001), dyspnea ( P<0.001), insomnia ( P<0.001), anorexia ( P<0.001), diarrhea ( P<0.001) and reflux ( P<0.001) in the surgical group were significantly higher than those in ESD group. There was no significant difference in disease-free survival or overall survival between the two groups ( P>0.05). Polyglycolic acid combined with autologous esophageal mucosal transplantation combined with temporary esophageal stent implantation could reduce the rate of esophageal scar stenosis after ESD [53.3% (24/45) VS 100.0% (55/55), P<0.001] and significantly reduce the number of postoperative dilation [1.00 (0.00, 5.00) VS 9.00 (5.00, 14.00), P<0.001] compared with balloon dilation alone. Conclusion:ESD is superior to traditional surgery for the treatment of circumferential superficial esophageal squamous cell neoplasm because of high operational safety, shorter operation time, less trauma, better postoperative life quality. Postoperative esophageal stenosis can still be well cured after endoscopic treatment. Therefore, ESD can be used as the first choice for the treatment of circumferential superficial esophageal squamous cell neoplasm.

Unlike healthy, non-transformed cells, the proteostasis network of cancer cells is taxed to produce proteins involved in tumor development. Cancer cells have a higher dependency on molecular chaperones to maintain proteostasis. The chaperonin T-complex protein ring complex (TRiC) contains eight paralogous subunits (CCT1-8), and assists the folding of as many as 10% of cytosolic proteome. TRiC is essential for the progression of some cancers, but the roles of TRiC subunits in osteosarcoma remain to be explored. Here, we show that CCT4/TRiC is significantly correlated in human osteosarcoma, and plays a critical role in osteosarcoma cell survival. We identify a compound anticarin-β that can specifically bind to and inhibit CCT4. Anticarin-β shows higher selectivity in cancer cells than in normal cells. Mechanistically, anticarin-β potently impedes CCT4-mediated STAT3 maturation. Anticarin-β displays remarkable antitumor efficacy in orthotopic and patient-derived xenograft models of osteosarcoma. Collectively, our data uncover a key role of CCT4 in osteosarcoma, and propose a promising treatment strategy for osteosarcoma by disrupting CCT4 and proteostasis.

In the process of animal fat deposition, the proliferation and differentiation of pre-adipocytes and the change of lipid droplet content in adipocytes are regulated by a series of transcription factors and signal pathways. Although researchers have conducted in-depth studies on the transcriptional regulation mechanisms of adipogenesis, there are relatively few reports on post-transcriptional modification on mRNA levels. The modification of mRNA m⁶A regulated by methyltransferase, demethylase and methylation reading protein is a dynamic and reversible process, which is closely related to fat deposition in animals. Fat mass and obesity associated proteins (FTO) act as RNA demethylases that affect the expression of modified genes and play a key role in fat deposition. This article summarized the mechanism of FTO-mediated demethylation of mRNA m⁶A in the process of animal fat deposition, suggesting that FTO may become a target for effective treatment of obesity. Moreover, this review summarized the development of FTO inhibitors in recent years.

Due to the complexity of bioactive ingredients in biological samples,the screening of target proteins is a complex process.Herein,a feasible strategy for directing protein immobilization on silica magnetic beads for ligand fishing based on SpyTag/SpyCatcher(ST/SC)-mediated anchoring is presented.Carboxyl functional groups on the surface of silica-coated magnetic beads(SMBs)were coupled with SC using the 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride/N-hydroxysulfosuccinimide method,named SC-SMBs.The green fluorescent protein(GFP),as the capturing protein model,was ST-labeled and anchored at a specific orientation onto the surface of SC-SMBs directly from relevant cell lysates via ST/SC self-ligation.The characteristics of the SC-SMBs were studied via electron microscopy,energy dispersive spectroscopy,and Fourier transform infrared spectroscopy.The spontaneity and site-specificity of this unique reaction were confirmed via electrophoresis and fluorescence analyses.Although the alkaline stability of ST-GFP-ligated SC-SMBs was not ideal,the formed isopeptide bond was unbreakable under acidic conditions(0.05 M glycine-HCl buffer,pH 1-6)for 2 h,under 20％ethanol solution within 7 days,and at most temperatures.We,therefore,present a simple and universal strategy for the preparation of diverse protein-functionalized SMBs for ligand fishing,prompting its usage on drug screening and target finding.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Objective:To explore the effect of Dachengqi Decoction on the postoperative recovery of laparoscopic gastrectomy under general anesthesia.Methods:From March 2015 to May 2018, 96 patients with gastric cancer undergoing laparoscopic gastrectomy under general anesthesia in our hospital were selected as the study objects and divided into two groups according to the random number table method. The control group received routine nursing. The observation group received the intervention of Dachengqi Decoction with ultrasonic conductivity on the basis of the control group. The recovery of gastrointestinal function, the levels of gas (serum gastrin), MTL (plasma motilin) and Quality of Recovery 40 (QoR40) were compared between the two groups.Results:The gastrointestinal function indexes of the observation group were better than those of the control group ( P<0.05). Compared with one day before operation, the levels of gas and MTL in the two groups were lower 24 hours after operation, but the levels of GAS and MTL in the observation group were (92.56±5.12), (258.58±5.59) ng/L, which were higher than (52.12±3.15), (185.63±4.12) ng/L in the control group ( t values were 46.608, 72.782, P<0.01). Compared with the pre intervention group, QoR40 scores of the two groups were improved after intervention, and the observation group was (198.56±5.58) points, which was higher than (152.12±2.63) points of the control group ( t value was 52.157, P<0.01). Conclusion:Dachengqi Decoction can promote the recovery of patients after laparoscopic gastrectomy under general anesthesia.
