To introduce a strategy for a case of severe pneumonia complicated with lung abscess caused by Fusobacterium necrotum.The pathogen was not identified,but the patient was still coughing up feverish bloody sputum after being treated with meropenem,linezolid and ornidazole.The results of detection of pathogen metagenomes in bronchoalveolar lavage fluid by posterior bronchoscopy suggested that the pathogen was Fusobacterium necrophorum,according to the characteristics of bacteria,the dynamic changes of clinical symptoms,liver and kidney function,body temperature and blood picture infection index,combined with the results of bacterial culture/drug sensitivity test,bronchoalveolar lavage fluid NGS and the pharmacokinetic/pharmacodynamic characteristics of antimicrobial agents,to propose an anti-infective regimen that is strategically adjusted to imipenem cilastatin(1.0 g,ivd,q8h)plus ornidazole(0.5 g,ivd,q12h)for the implementation of pharmaceutical care after adoption by physicians.After 21 days,the patient's severe infection and lung abscess was controlled and patient was discharged.In this case,clinical pharmacists study the bacterial characteristics of Fusobacterium necrotum,review a large number of domestic and foreign literature to track the frontier knowledge of antimicrobial agents,and use their own expertise to provide effective pharmaceutical support for the clinical team,to assist clinical team in the diagnosis and treatment of rare infections,to achieve professional value.

Digital intraoral scanning is a hot topic in the field of oral digital technology.In recent years,digital intra-oral scanning has gradually become the mainstream technology in orthodontics,prosthodontics,and implant dentistry.The precision of digital intraoral scanning and the accuracy and stitching of data collection are the keys to the success of the impression.However,the operators are less familiar with the intraoral scanning characteristics,imaging process-ing,operator scanning method,oral tissue specificity of the scanned object,and restoration design.Thus far,no unified standard and consensus on digital intraoral scanning technology has been achieved at home or abroad.To deal with the problems encountered in oral scanning and improve the quality of digital scanning,we collected common expert opin-ions and sought to expound the causes of scanning errors and countermeasures by summarizing the existing evidence.We also describe the scanning strategies under different oral impression requirements.The expert consensus is that due to various factors affecting the accuracy of digital intraoral scanning and the reproducibility of scanned images,adopting the correct scanning trajectory can shorten clinical operation time and improve scanning accuracy.The scanning trajec-tories mainly include the E-shaped,segmented,and S-shaped methods.When performing fixed denture restoration,it is recommended to first scan the abutment and adjacent teeth.When performing fixed denture restoration,it is recommend-ed to scan the abutment and adjacent teeth first.Then the cavity in the abutment area is excavated.Lastly,the cavity gap was scanned after completing the abutment preparation.This method not only meets clinical needs but also achieves the most reliable accuracy.When performing full denture restoration in edentulous jaws,setting markers on the mucosal tissue at the bottom of the alveolar ridge,simultaneously capturing images of the vestibular area,using different types of scanning paths such as Z-shaped,S-shaped,buccal-palatal and palatal-buccal pathways,segmented scanning of dental arches,and other strategies can reduce scanning errors and improve image stitching and overlap.For implant restora-tion,when a single crown restoration is supported by implants and a small span upper structure restoration,it is recom-mended to first pre-scan the required dental arch.Then the cavity in the abutment area is excavated.Lastly,scanning the cavity gap after installing the implant scanning rod.When repairing a bone level implant crown,an improved indi-rect scanning method can be used.The scanning process includes three steps:First,the temporary restoration,adjacent teeth,and gingival tissue in the mouth are scanned;second,the entire dental arch is scanned after installing a standard scanning rod on the implant;and third,the temporary restoration outside the mouth is scanned to obtain the three-di-mensional shape of the gingival contour of the implant neck,thereby increasing the stability of soft tissue scanning around the implant and improving scanning restoration.For dental implant fixed bridge repair with missing teeth,the mobility of the mucosa increases the difficulty of scanning,making it difficult for scanners to distinguish scanning rods of the same shape and size,which can easily cause image stacking errors.Higher accuracy of digital implant impres-sions can be achieved by changing the geometric shape of the scanning rods to change the optical curvature radius.The consensus confirms that as the range of scanned dental arches and the number of data concatenations increases,the scanning accuracy decreases accordingly,especially when performing full mouth implant restoration impressions.The difficulty of image stitching processing can easily be increased by the presence of unstable and uneven mucosal mor-phology inside the mouth and the lack of relatively obvious and fixed reference objects,which results in insufficient ac-curacy.When designing restorations of this type,it is advisable to carefully choose digital intraoral scanning methods to obtain model data.It is not recommended to use digital impressions when there are more than five missing teeth.

Objective To analyze the effect of fisetin against venous thrombosis in rats.Methods Seventy SD rats were randomly divided into the following groups:sham-operation group,model group,fisetin 45 mg/kg,15 mg/kg,5 mg/kg groups,and aspirin group(47 mg/kg).The corresponding medication was administered by gavage once a day consecutively(the sham-operation group and the model group were given 0.5％carboxymethyl cellulose sodium solution with 10 mL/kg,respectively)for 7 consecutive days.One hour after the last administration,the rats were anesthetized,the lower part of the intersection of inferior vena cava and left renal vein was ligated with silk thread(no ligation in the sham-operation group),and the abdominal wall was sutured.Two hours later,the abdominal cavity was reopened,the other venous branches 1.5 cm away from the ligation site were closed with the artery clamp,and blood was collected from the abdominal aorta.The anticoagulant ratio of 3.8％sodium citrate∶whole blood was 1∶9.The venous thrombus 1 cm down from the ligation point of the intersection of inferior vena cava and left renal vein was cut and the thrombus was separated.The residual blood was dried with filter paper,weighed and recorded.Plasma was taken after anticoagulant blood centrifugation.The levels of plasma antithrombin-Ⅲ(AT-Ⅲ),protease C(PC),plasminogen(PLG),and plasminogen activator inhibitor(PAI-1)were detected by ELISA kits.Results Compared with the model group,the weight of thrombus in fisetin 45 mg/kg group and aspirin 47 mg/kg group decreased(P＜0.01).The content of AT-Ⅲ in three fisetin groups increased(all P＜0.05).The content of PC in fisetin 45 mg/kg increased(P＜0.05).The content of PLG and PAI-1 in fisetin 45 mg/kg group decreased(both P＜0.05).Conclusion Fisetin has the effect against venous thrombosis in vivo,and the effect is related to the upregulation of AT-Ⅲ and PC and the downregulation of PLG and PAI-1.

Objectives:The present study evaluated the impact of ablation pain during pulmonary vein isolation(PVI)on catheter-tissue contact at different regions. Methods:Forty consecutive patients with atrial fibrillation(AF)referred to Central China Fuwai Hospital for catheter radiofrequency ablation from February to May 2023 were enrolled.The pulmonary veins on each side were divided into 8 regions.The catheter-tissue contact force(CF)and the number of ablation contact stability(>50%catheter attach time CF≥10 g)of each ablation lesion were analyzed.Pain scores during the ablation were assessed using the Faces Pain Scale-Revised and the maximum score was taken for each ablation region.Based on the pain scores,in each region,20 cases with higher pain scores were categorized into the pain group and 20 cases with lower pain scores were categorized into the normal group.The CF characteristics of each region and the relationship with ablation induced pain were analyzed. Results:A total of 3 832 lesions were recorded in 40 patients with AF,with a mean CF of(12.2±7.8)g.Among them,the CF in the pain group was significantly lower than that in the normal group([11.1±5.1]g vs.[13.4±4.8]g,P<0.05).The top region of the right pulmonary vein was the region with the largest CF(16.5±5.8)g,and the upper part of the left anterior wall(at the ridge between the left atrial appendage)was the region with the smallest CF(7.5±3.7)g.At the bottom of right pulmonary vein,right lower posterior wall,left pulmonary vein,and left posterior wall,as well as the middle region of left posterior wall,and upper region of left posterior wall,the CF was significantly smaller in the pain group than that in the normal group(all P<0.05).Of the 3 832 lesions,2 193(57.2%)were stable lesions,and the proportion of stable lesions in the pain group was significantly lower than that in the normal group(55.2%vs.59.5%,P<0.05).In the right pulmonary vein bottom,right lower posterior wall,left lower anterior wall,left pulmonary vein bottom,and left lower posterior wall,the proportion of stable lesions was significantly lower in the pain group than in the normal group(all P<0.05).In addition,the ratio of stable lesions in left pulmonary vein regions was lower than in the right(54.2%vs.60.5%,P<0.05).In the upper part of the left anterior wall(at the ridge between the left atrial appendage),only 88(39.3%)of the 224 lesions in 40 patients were stable lesions. Conclusions:Pain during ablation significantly affects the stability of the catheter to tissue.Monitoring real-time CF during PVI may have important implications for improving ablation efficacy,especially in regions with more intense pain.

Background:Slight mucosal lesions in the early stage of gastric cancer(GC)are difficult to recognize,and the miss rate of early GC by conventional endoscopy is high.Artificial intelligence(AI)systems can assist in the identification of gastric neoplastic lesions and reduce miss rate,but it is not clear whether AI-assisted endoscopic screening is cost-effective.Aims:The subjects of this study were to evaluate the cost-effectiveness of a population-based endoscopy screening program for GC in high-incidence countries(China,Japan and South Korea),and to explore the applicability of domestic AI--Intelligent and real-time endoscopy analytical device(IREAD)-assisted endoscopy for GC screening in these three countries.Methods:Based on the natural history of GC,a Markov model with cycle year of 1 year was constructed to compare cost-effectiveness of two strategies for GC screening in recommended age group:no screening(the control strategy),conventional endoscopy screening and IREAD-assisted endoscopy screening.Data such as transition probabilities of different states and treatment costs were obtained from previously published studies.The cost-effectiveness analysis was conducted from the perspective of society by calculating cost,Quality adjusted life years(QALY),Incremental cost effectiveness ratio(ICER).Results:The cohort results showed that 15.87%and 24.52%of GC-related deaths could be respectively avoid by conventional endoscopy screening and IREAD-assisted endoscopy screening in China,which the screening effects were similar to Japan;In South Korea,Conventional endoscopic screening and IREAD-assisted endoscopic screening averted 41.34%and 53.15%of GC-related deaths,respectively.Between the two strategies,IREAD-assisted endoscopic screening is more economic,with ICER of $34 827.61/QALY,$87 978.71/QALY and $10 574.30/QALY in China,Japan and South Korea,respectively,which were lower than the willingness-to-pay(WTP)threshold.Conclusions:When the threshold of WTP is 3 times Gross domestic product per capita,the application of AI-assisted endoscopy for GC screening in age-specific population in high-incidence countries may be more cost-effective.Meanwhile,this study provides important evidence for the promotion of domestic IRAED-assisted endoscopy in GC screening in China,Japan and South Korea.

Hepatocellular carcinoma (HCC) is the most common primary hepatic malign-ancy in clinic. The prognosis of patients remains extremely poor because of the high malignancy and easy recurrence and metastasis of HCC. In recent years, the roles of platelets in promoting the malignant progression of HCC have increasingly attracted much attention. It is known that platelets could promote HCC cells proliferation and invasion through tumor microenvironment. On the other hand, platelets are capable to promote HCC cells distant metastasis by facilitating tumor cells evasion of immune surveillance. Besides, the platelet-derived growth factors and proangiogenic factors are also involved in the proliferation, invasiveness, and neovascularization of HCC. In addition, patients with HCC normally have a background of cirrhosis, and it is still controversial that whether the thrombocytopenia by portal hypertension and hypersplenism can promote the malignant progress of HCC. In view of this, the diagnostic and prognostic value of platelet levels, as well as platelet-associated scores in HCC have increasingly become research focus. The authors elaborate the detailed mechanisms of platelets in malignant progression of HCC, and discuss the recent research progress of platelets as effective diagnostic or prognostic tools for the assessment of HCC, which is of great importance to optimize the current treatment regimen and explore novel therapeutic strategies against HCC.

Objective:To explore the effectiveness of the artificial intelligence-endoscopic ultrasound (AI-EUS) biliary and pancreatic recognition system in assisting the recognition of EUS images.Methods:Subjects who received EUS due to suspicious biliary and pancreatic diseases from December 2019 to August 2020 were prospectively collected from the database of Department of Gastroenterology, Renmin Hospital of Wuhan University. Pancreatic EUS images of 28 subjects were included for recognition of pancreas standard station. EUS images of bile duct of 29 subjects were included for recognition of bile duct standard station. Eight new endoscopists from the Gastroenterology Department of Renmin Hospital of Wuhan University read the 57 EUS videos with and without the assistance of AI-EUS biliary and pancreatic recognition system. Accuracy of endoscopists' identification of biliary and pancreatic standard sites with and without the assistance of AI-EUS was compared.Results:The accuracy of pancreas standard station identification of the new endoscopists increased from 67.2% (903/1 344) to 78.4% (1 054/1 344) with the assistance of AI-EUS. The accuracy of bile duct standard station identification increased from 56.4% (523/928) to 73.8% (685/928).Conclusion:AI-EUS biliary and pancreatic recognition system can improve the accuracy of EUS images recognition of biliary and pancreatic system, which can assist diagnosis in clinical work.

Objective:To construct the concept and its conceptual framework of hospital health literacy(HHL) for exploring the HHL promotion mechanism in the country.Methods:Based on the proceduralised grounded theory, twelve middle or senior managers of hospitals were selected for in-depth interviews and three hospitals were selected for field research from July 2021 to February 2022. Open coding, axial coding, and selective coding were used in data analysis, establishing the concept of HHL and its conceptual framework in China.Results:The conceptual framework of HHL was composed of an internal driver mechanism(hospitals improve their health literacy promotion management system, staff-led health literacy promotion, health literacy promoting physical environment construction), and an external driver mechanism(cooperate with external organizations and institutions to conduct health literacy promotion). The concept of HHL in China was derived as follows: the combination of supportive environments and human resources that health care organizations have in place can improve access and understandability of health information and simplify healthcare services to help patients of different health literacy levels more easily obtain, process, and understand health information as well as to make the most of medical services.Conclusions:Hospital health literacy promotion mechanism in China is a synergy between internal and external driver mechanisms.
