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.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To analyze the multimodal ultrasound characteristics of primary breast cancer and sentinel lymph node (SLN) and to establish a nomogram model for predicting SLN metastasis in invasive breast cancer, thereby providing reference for precise clinical diagnosis and treatment.Methods:A total of 329 patients diagnosed with invasive breast cancer and admitted to the Affiliated Hospital of Nanjing University of Chinese Medicine from June 2018 to October 2023 were retrospectively enrolled. They were randomly divided into a training cohort ( n=230) and a validation cohort ( n=99) in a ratio of 7 to 3. In the training cohort, ultrasound findings and clinical parameters were analyzed, univariate and multivariate Logistic regression analyses were used to identify independent predictive factors for SLN metastasis, and a nomogram model was constructed based on these factors. The ROC curve, calibration curve, and decision curve analysis (DCA) were plotted between the training and validation cohorts to assess the discrimination, calibration, and clinical applicability of the nomogram model. Results:Regression analysis identified 3 independent risk factors for establishing the nomogram prediction model: ratio of the long diameter to the short diameter of SLN ( P=0.020), lymphatic contrast-enhanced ultrasound (LCEUS) enhancement pattern ( P<0.001) and intravenous contrast-enhanced ultrasound (ICEUS) enhancement mode ( P=0.002). The area under the curve (AUC) of the training cohort was 0.888, the accuracy was 0.865; the AUC of the validation cohort was 0.870, the accuracy was 0.859, demonstrating good predictive performance of the model in both cohorts. The calibration curve demonstrated that the nomogram has a strong concordance between predicted and actual probability. DCA demonstrated that the nomogram could increase net benefit within a certain probability threshold range. Conclusions:The nomogram based on ratio of the long diameter to the short diameter of SLN, LCEUS enhancement pattern and ICEUS enhancement mode can effectively predict SLN status in patients with invasive breast cancer, facilitating precise diagnosis and treatment.

Objective To determine the median effective dose(ED50)of ropivacaine for spinal anesthesia in sub-high altitude cesarean sections.Methods A total of 30 parturients from sub-high altitudes received initial 14 mg(1.4 mL)of 1%ropivacaine intrathecally.Effectiveness was defined by sensory block to T6 within 15 minutes without additional epidural anesthesia.Doses were adjusted by±1 mg based on response.ED50 and 95%CI were estimated using Dixon's method and isotonic regression.Adverse reactions were noted.Results Thirty parturients with an average age of(30.88±5.56)years,gestational weeks of(40±1.41)weeks,height of(156.69±5.80)cm,and weight of(67.44±10.48)kg were studied.The ED50 was 10.68 mg(95%CI:9.65-12.58 mg)by Dixon's method and 10.33 mg(95%CI:9.41-12.07 mg)by isotonic regression.Intraoperatively,8 cases of hypotension,1 case of bradycardia,and 7 cases of nausea and vomiting were observed,no hypertension or shivering occurred among the parturients.Conclusion The ED50 for ropivacaine in sub-high altitude cesarean sections is 10.68 mg,which is higher than the currently known ED50 required for patients in plain areas.

Objective To analyze the risk factors and survival status of Epstein-Barr virus(EBV)infection in pa-tients with aplastic anemia(AA)after haploid allogeneic hematopoietic stem cell transplantation(Haplo-HSCT).Methods Clinical data of 78 AA patients who underwent Haplo-HSCT in the hematology department of a hospital from January 1,2019 to October 31,2022 were analyzed retrospectively.The occurrence and onset time of EBV viremia,EBV-related diseases(EBV diseases),and post-transplant lymphoproliferative disorders(PTLD)were ob-served,risk factors and survival status were analyzed.Results Among the 78 patients,38 were males and 40 were females,with a median age of 33(9-56)years old;53 patients experienced EBV reactivation,with a total inci-dence of 67.9％,and the median time for EBV reactivation was 33(13,416)days after transplantation.Among pa-tients with EBV reactivation,49 cases(62.8％)were simple EBV viremia,2 cases(2.6％)were possible EBV di-seases,and 2 cases(2.6％)were already confirmed EBV diseases(PTLD).Univariate analysis showed that age 1＜40 years old at the time of transplantation,umbilical cord blood infusion,occurrence of acute graft-versus-host disease(aGVHD)after transplantation,and concurrent cytomegalovirus(CMV)infection were independent risk fac-tors for EBV reactivation in AA patients after Haplo-HSCT.Multivariate analysis showed that concurrent CMV in-fection was an independent risk factor for EBV reactivation in A A patients after Haplo-HSCT(P=0.048).Ritu-ximab intervention before stem cell reinfusion was a factor affecting the duration of EBV reactivation(P＜0.05).The mortality of EBV viremia,EBV diseases,and PTLD alone were 8.2％,50.0％,and 100％,respectively.The 2-year overall survival rate of patients with and without EBV reactivation were 85.3％,and 90.7％,respectively,difference was not statistically significant(P=0.897).However,patients treated with rituximab had 2-year lower survival rate than those who did not use it,with a statistically significant difference(P=0.046).Conclusion EBV reactivation is one of the serious complications in AA patients after Haplo-HSCT,which affects the prognosis and survival of patients.

The alterations of serum biological endogenous chemicals in rats with phlegm dampness accumulation syndrome of prehypertension (PHT) were interfered by Banxia Baizhu Tianma decoction (BBT), and the metabolic regulatory pathway of BBT was clarified using serum metabonomics analysis. To replicate the rat model of prehypertension phlegm dampness syndrome, blood pressure, behavioral markers, and serum biochemical markers of rats were collected. BBT's effectiveness in controlling blood pressure and blood lipids was assessed, and changes in endogenous small molecules in rat serum were determined using UPLC-Q-Orbitrap MS metabolic analysis. The results showed that BBT could regulate 9 metabolites, including arachidonic acid, cholic acid, glycodeoxycholic acid, N-adenosyltyrosine, arginine, lysophosphatidylethanolamine (20:0/0:00), lysophospholipid (P-18:0), lysophospholipid (18:0), lysophospholipid (22:5(7Z,10Z,13Z,16Z,19Z)). MetaboAnalyst was used to analyze the metabolic pathway. There were 7 metabolic pathways closely related to the change of blood pressure in rats, among which arachidonic acid metabolic pathway was the most critical. The metabolism difference foreign body in the model rats tends to return to the normal level, which provides a research basis for the mechanism of BBT from the perspective of metabonomics. This study was approved by the Experimental Animal Welfare Ethics Review Committee of Shandong University of Traditional Chinese Medicine (approval number: SDUTCM20211103001).
