Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Objective:To evaluate the accuracy, completeness, and reproducibility of domestic open-source large language models (LLM) in diabetic retinopathy (DR) patient education, and to explore their potential as intelligent virtual assistants for DR patient education.Methods:A total of 41 questions and answers related to the diagnosis and treatment of DR in five categories, namely risk factors, screening and examination, symptoms and staging, diagnosis, treatment and prognosis.All questions were repeated twice as a " new dialogue" in the LLM, and all the answers were recorded.Three senior fundus physicians independently evaluated the answers on a 6-point Likert scale for accuracy and a 3-point Likert scale for completeness and repeatability, and for each answer, the evaluator was asked to make a recommendation between the LLM and the manual answers.Five questions were randomly selected to evaluate the three open source LLM, ERNIE Bot 3.5, Qwen and Kimi chat, and the LLM with the best overall performance was selected for further evaluation in the full question bank.Results:Among the three LLM, Kimi chat had the best overall performance, Kimi chat performed best, with percentages of 6 for accuracy, 3 for completeness, and 3 for repeatability among the 5 questions at 90%, 90%, and 100%, respectively.For all questions answered, the number of words in manual replies was 106 (70, 202), which was significantly lower than 505 (386, 600) in Kimi chat ( Z=-7.866, P<0.001).There was no significant correlation between the number of Kimi chat replies and the accuracy score ( rs=-0.044, P=0.492), but it was positively correlated with the integrity score ( rs=0.239, P<0.001).The interclass correlation coefficient for accuracy and completeness scores were above 0.700 among three evaluators, with the highest agreement for repeatability at 0.853, followed by completeness of the first response at 0.771.The proportion of responses ≥5 points for accuracy was 87.0%(214/246), the proportion ≥2 points for completeness was 98.0%(241/246), and the proportion higher than 70% for repeatability was 78.5%(193/246).Kimi chat excelled in answering basic questions about the disease such as disease definition, staging, frequency of screening, and common risk factors, but performed poorly on questions involving treatment choices that require a doctor's professional judgment.The proportion of evaluators choosing Kimi chat responses as superior was 69.5% (171/246), and the reasons for non-selection included lack of characteristic answers, inclusion of too much irrelevant information, and lack of responses to questions requiring a high degree of medical expertise. Conclusions:Kimi chat answers DR-related diagnostic questions in a detailed and well-organized manner, with a high degree of accuracy, completeness and reproducibility.

Objective To investigate the value of magnetic resonance image compilation(MAGiC)sequences for diagnosing quantitatively osteonecrosis of the femoral head.Methods The hip joint MAGiC images of 57 femoral head osteonecrosis patients confirmed by clinical history,symptoms and conventional imaging in some hospital from February 2022 to August 2023 were analyzed retrospectively.The Ti,T2 and proton density(PD)values of the necrotic areas of the femoral heads and the bone marrow edema areas of the femoral necks were measured and compared with the normal values of corresponding areas,and ROC curves were plotted for the parameters with statistically significant differences to evaluate its diagnostic efficacy for the femoral head osteonecrosis and femoral neck bone marrow edema;the differences in the Ti,T2 and PD values of the patients with different ARCO stages were compared.SPSS 26.0 software was used for data analysis.Results The T1 value of the necrotic area was significantly higher than that of the normal femoral head,the T2 and PD values were significantly lower,and the differences were statistically significant(P＜0.001).The T1 value of the edema area was significantly higher than that of the normal femoral neck,the PD value was significantly lower,and the differences were statistically significant(P＜0.001).The T2 and PD values of the necrotic area were significantly lower than those of the edema area,and the differences were statistically significant(P＜0.001).The AUCs of the T1,T2 and PD in the necrotic area for diagnosing femoral head osteonecrosis were 1.000,0.947 and 0.914,with sensitivities of 100.0％,89.2％and 92.8％and specificities of 100.0％,96.7％and 76.7％,respectively,and the three quantitative values proved to have high diagnosis efficacy.The AUCs of the T1 and PD in the edema area for diagnosing bone marrow edema were 0.969 and 0.797,with sensitivities of 90.4％and 86.5％and specificities of 100.0％and 60.0％,respectively,and the T,showed high diagnosis efficacy.As the ARCO stage progressed,the T1 value of the necrotic area gradually increased and the T2 and PD values gradually decreased.The edema area had the lowest Ti,T2 and PD values in stage Ⅰ and the highest Ti,T2 and PD values in stage Ⅱ.Conclusion The Ti,T2 and PD of the MAGiC sequences are effective for the diagnosis of femoral head osteonecrosis,the T1 and PD have high efficacy for diagnosing bone marrow edema of the femoral neck,and the T2 and PD gains advantages in differentiating osteonecrosis of the femoral head from bone marrow edema of the femoral neck.MAGiC sequences can provide objective references for quantitative diagnosis of femoral head osteonecrosis.[Chinese Medical Equipment Journal,2024,45(3):66-70]

Objective:To investigate the correlation of the clinical characteristics,fever characteristics,serum biomarkers with cytokine release syndrome (CRS) in patients with relapsed/refractory multiple myeloma (R/R MM) treated with chimeric antigen receptor T cell (CAR-T) immunotherapy. Methods:104 R/R MM patients who received CAR-T cell therapy at the Affiliated Hospital of Xuzhou Medical University from June 2017 to November 2021 were included,and the correlations of their clinical characteristics,fever characteristics,serum biomarkers with the severity of CRS were analyzed. Results:Among 104 R/R MM patients receiving CAR-T treatment,no CRS was observed in 8 cases (7.7％),and 96 cases (92.3％) developed CRS. Patients with high-risk cytogenetics had a higher risk of developing CRS (P=0.040),while patients who had previously received autologous hematopoietic stem cell transplantation (ASCT) had a lower risk of developing CRS (P=0.004). There was a significant difference in the duration of fever between patients with grade 1-2 and grade 3-5 CRS (P=0.006). The highest body temperature varied among patients with different treatment regimens (P=0.001). The decrease in total protein in patients with CRS was more significant than in patients without CRS (P=0.002). Within one month after CAR-T cell infusion,the degree of albumin recovery in patients with grade 3-5 CRS was lower than that in patients with grade 0-2 CRS (P=0.037). Compared to patients with grade 1-2 CRS,patients with grade 3-5 CRS showed a significant increase in heart rate after CAR-T cell infusion (P=0.013),while IL-6,C-reactive protein (CRP),and serum ferritin (SF) also showed significant increases (P=0.007,P<0.001,P=0.003). Conclusion:High-risk cytogenetics is a risk factor for severe CRS. Long duration of fever is a clinical characteristic of severe CRS. CRP can better reflect the severity of CRS.

Objective To investigate the distribution and antimicrobial resistance profiles of the common pathogens isolated from urine from 2015 to 2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods The bacterial strains were isolated from urine and identified routinely in 51 hospitals across China in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Antimicrobial susceptibility was determined by Kirby-Bauer method,automatic microbiological analysis system and E-test according to the unified protocol.Results A total of 261 893 nonduplicate strains were isolated from urine specimen from 2015 to 2021,of which gram-positive bacteria accounted for 23.8％(62 219/261 893),and gram-negative bacteria 76.2％(199 674/261 893).The most common species were E.coli(46.7％),E.faecium(10.4％),K.pneumoniae(9.8％),E.faecalis(8.7％),P.mirabilis(3.5％),P.aeruginosa(3.4％),SS.agalactiae(2.6％),and E.cloacae(2.1％).The strains were more frequently isolated from inpatients versus outpatients and emergency patients,from females versus males,and from adults versus children.The prevalence of ESBLs-producing strains in E.coli,K.pneumoniae and P.mirabilis was 53.2％,52.8％and 37.0％,respectively.The prevalence of carbapenem-resistant strains in E.coli,K.pneumoniae,P.aeruginosa and A.baumannii was 1.7％,18.5％,16.4％,and 40.3％,respectively.Lower than 10％of the E.faecalis isolates were resistant to ampicillin,nitrofurantoin,linezolid,vancomycin,teicoplanin and fosfomycin.More than 90％of the E.faecium isolates were ressitant to ampicillin,levofloxacin and erythromycin.The percentage of strains resistant to vancomycin,linezolid or teicoplanin was＜2％.The E.coli,K.pneumoniae,P.aeruginosa and A.baumannii strains isolated from ICU inpatients showed significantly higher resistance rates than the corresponding strains isolated from outpatients and non-ICU inpatients.Conclusions E.coli,Enterococcus and K.pneumoniae are the most common pathogens in urinary tract infection.The bacterial species and antimicrobial resistance of urinary isolates vary with different populations.More attention should be paid to antimicrobial resistance surveillance and reduce the irrational use of antimicrobial agents.

Objective To understand the distribution and changing resistance profiles of clinical isolates of Enterococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Enterococcus according to the unified protocol of CHINET program by automated systems,Kirby-Bauer method,or E-test strip.The results were interpreted according to the Clinical & Laboratory Standards Institute(CLSI)breakpoints in 2021.WHONET 5.6 software was used for statistical analysis.Results A total of 124 565 strains of Enterococcus were isolated during the 7-year period,mainly including Enterococcus faecalis(50.7％)and Enterococcus faecalis(41.5％).The strains were mainly isolated from urinary tract specimens(46.9％±2.6％),and primarily from the patients in the department of internal medicine,surgery and ICU.E.faecium and E.faecalis strains showed low level resistance rate to vancomycin,teicoplanin and linezolid(≤3.6％).The prevalence of vancomycin-resistant E.faecalis and E.faecium was 0.1％and 1.3％,respectively.The prevalence of linezolid-resistant E.faecalis increased from 0.7％in 2015 to 3.4％in 2021,while the prevalence of linezolid-resistant E.faecium was 0.3％.Conclusions The clinical isolates of Enterococcus were still highly susceptible to vancomycin,teicoplanin,and linezolid,evidenced by a low resistance rate.However,the prevalence of linezolid-resistant E.faecalis was increasing during the 7-year period.It is necessary to strengthen antimicrobial resistance surveillance to effectively identify the emergence of antibiotic-resistant bacteria and curb the spread of resistant pathogens.

Objective To examine the changing antimicrobial resistance profile of Enterobacter spp.isolates in 53 hospitals across China from 2015 t0 2021.Methods The clinical isolates of Enterobacter spp.were collected from 53 hospitals across China during 2015-2021 and tested for antimicrobial susceptibility using Kirby-Bauer method or automated testing systems according to the CHINET unified protocol.The results were interpreted according to the breakpoints issued by the Clinical & Laboratory Standards Institute(CLSI)in 2021(M100 31st edition)and analyzed with WHONET 5.6 software.Results A total of 37 966 Enterobacter strains were isolated from 2015 to 2021.The proportion of Enterobacter isolates among all clinical isolates showed a fluctuating trend over the 7-year period,overall 2.5％in all clinical isolates amd 5.7％in Enterobacterale strains.The most frequently isolated Enterobacter species was Enterobacter cloacae,accounting for 93.7％(35 571/37 966).The strains were mainly isolated from respiratory specimens(44.4±4.6)％,followed by secretions/pus(16.4±2.3)％and urine(16.0±0.9)％.The strains from respiratory samples decreased slightly,while those from sterile body fluids increased over the 7-year period.The Enterobacter strains were mainly isolated from inpatients(92.9％),and only(7.1±0.8)％of the strains were isolated from outpatients and emergency patients.The patients in surgical wards contributed the highest number of isolates(24.4±2.9)％compared to the inpatients in any other departement.Overall,≤ 7.9％of the E.cloacae strains were resistant to amikacin,tigecycline,polymyxin B,imipenem or meropenem,while ≤5.6％of the Enterobacter asburiae strains were resistant to these antimicrobial agents.E.asburiae showed higher resistance rate to polymyxin B than E.cloacae(19.7％vs 3.9％).Overall,≤8.1％of the Enterobacter gergoviae strains were resistant to tigecycline,amikacin,meropenem,or imipenem,while 10.5％of these strains were resistant to polycolistin B.The overall prevalence of carbapenem-resistant Enterobacter was 10.0％over the 7-year period,but showing an upward trend.The resistance profiles of Enterobacter isolates varied with the department from which they were isolated and whether the patient is an adult or a child.The prevalence of carbapenem-resistant E.cloacae was the highest in the E.cloacae isolates from ICU patients.Conclusions The results of the CHINET Antimicrobial Resistance Surveillance Program indicate that the proportion of Enterobacter strains in all clinical isolates fluctuates slightly over the 7-year period from 2015 to 2021.The Enterobacter strains showed increasing resistance to multiple antimicrobial drugs,especially carbapenems over the 7-year period.
