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.

Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.

Objective To observe the effect of acupoint sticking therapy along meridians on gastrointestinal function recovery in patients after lumbar internal fixation surgery.Methods From January 2020 to March 2022,125 patients with lumbar degenerative diseases were admitted to our hospital's Department of Orthopaedics and divided into two groups:control(n = 62)and acupoint sticking therapy(n = 63).The control group received standard postoperative care for lumbar internal fixation,while the experimental group received routine care based on acupoint sticking therapy along meridians.The NVAS scores for postoperative nausea and vomiting,abdominal distension and pain,bowel sound,initial exhaust,and defecation time were compared between the two groups.Results Both groups experienced gastrointestinal problems to varied degrees following surgery.The experimental group had signifi-cantly lower rates of nausea,NVAS score,vomiting grade,abdominal distension,return to normal bowel sounds,and time of first exhaust and bowel movement compared to the control group(P<0.05).However,there were no significant differences in abdominal pain and abdominal circumference(P>0.05).There were no adverse reactions in either group.The incidence of postoperative abdominal distension,nausea and vomiting in the observation group was lower than that in the control group,and the difference was statistically significant(P<0.05).Conclusion Acupoint sticking therapy along meridians could accelerate the recovery of gastrointestinal function of patients after lumbar internal fixation,promote rapid recovery after surgery,and improve quality of life.

Massive rotator cuff tears, with mean tendon tears>5 cm or involving two or more tendons in a tear, often result in shoulder pain, stiffness, limited range of motion and impaired function, significantly impacting the patients′ quality of life. At present, massive rotator cuff tears are mainly treated surgically with joint cleaning, rotator cuff repair and patch graft repair, etc, but the problems such as tendon end retraction and high rotator tension after surgical repair lead to high postoperative retear rate. The autogenous long head of biceps tendon (LHBT), as an autograft which has the advantages of high accessibility and low cost, has been employed in the repair of massive rotator cuff tears. However, there is still controversy in the choice of specific surgical method. To this end, the authors reviewed the research progress on the application of LHBT in the repair of massive rotator cuff tears, aiming to provide reference for its clinical treatment.

Objective:To compare the efficacy of superior capsular reconstruction using a "sandwich" patch graft versus a fascia lata autograft in the treatment of irreparable massive rotator cuff tears (IMRCTs).Methods:A retrospective analysis was conducted on 50 patients with IMRCTs who underwent superior capsule reconstruction at Ningbo Medical Center Li Huili Hospital from January 2019 to May 2021. Patients were categorized into two groups based on the type of graft used: the "sandwich" group (27 patients), utilizing a "sandwich" patch graft, and the fascia lata group (23 patients), utilizing a simple fascia lata graft. The "sandwich" group consisted of 10 males and 17 females with a mean age of 65.6±5.7 years (range, 55-76 years), including 6 cases on the left shoulder and 21 cases on the right shoulder. The fascia lata group comprised 10 males and 13 females with a mean age of 65.5±4.2 years (range, 56-72 years), including 4 cases on the left shoulder and 19 cases on the right shoulder. Clinical outcomes were assessed preoperatively and at 1 week, 6 months, 1 year, and 2 years postoperatively using the American Shoulder and Elbow Surgeons (ASES) score, the University of California Los Angeles (UCLA) score, and the visual analogue scale (VAS) for pain and shoulder activity. Imaging outcomes, including acromio humeral distance (AHD) and graft status, were evaluated via radiographs or MRI.Results:The follow-up duration was 40.0±8.4 months (range, 26-54 months) for all patients. The "sandwich" group demonstrated significantly better outcomes compared to the fascia lata group. Improvements were noted in the ASES score (90.1±8.7 vs. 66.8±22.0), ASES score improvement (58.0±11.8 vs. 36.7±24.2), UCLA score (31.0±3.1 vs. 23.0±8.7), UCLA score improvement (20.1±4.5 vs. 12.7±9.2), active elevation (160.0°±21.3° vs. 124.8°±37.4°), active elevation improvement (70.2°±31.4° vs. 33.7°±42.4°), external rotation (35.0°±9.0° vs. 29.0°±6.9°), external rotation improvement (11.3°±7.3° vs. 7.2°±10.4°), AHD (6.4±1.5 mm vs. 4.4±1.0 mm), AHD improvement (3.0±1.6 mm vs. 1.5±1.0 mm), the difference was statistically significant ( P<0.05). The graft healing rate of the "sandwich" group reached 93%, which was higher than the 74% in the fascia lata group, but the difference was not statistically significant (χ 2=1.984, P=0.159). One case of subcutaneous hematoma was reported in the fascia lata group postoperatively. Additionally, two patients in the fascia lata group reported mild thigh discomfort at the last follow-up, which did not impair walking. No cases of infection, joint stiffness, or vascular or nerve damage were observed. Conclusion:Superior capsular reconstruction using a "sandwich" patch graft significantly enhances the healing rate of grafts and short-term postoperative clinical outcomes in patients with irreparable massive rotator cuff tears.

Objective:To investigate the clinical characteristics and prognostic factors of TCF3-PBX1 fusion gene-positive childhood B-cell precursor acute lymphoblastic leukemia (B-ALL).Methods:The clinical data of 1 287 newly diagnosed children with B-ALL who were admitted to five hospital in Fujian province (Fujian Medical University Union Hospital, the First Affiliated Hospital of Xiamen University, Zhangzhou Affiliated Hospital of Fujian Medical University, Quanzhou First Hospital Affiliated to Fujian Medical University, Nanping First Hospital of Fujian Province) from April 2011 to December 2020 were retrospectively analyzed. According to the results of TCF3-PBX1 fusion gene testing, all the patients were divided into TCF3-PBX1-positive group and TCF3-PBX1-negative group. The clinical characteristics, early treatment response [minimal residual disease (MRD) at middle stage and end of induction chemotherapy] and long-term efficacy [overall survival (OS) and event-free survival (EFS)] of the patients in both groups were compared. Kaplan-Meier method was used for survival analysis. The prognostic factors of TCF3-PBX1-positive B-ALL were analyzed by using Cox proportional hazards model. Among 83 children with TCF3-PBX1-positive B-ALL, the treatment regimens, risk stratification and efficacy evaluation of 62 cases were performed by using Chinese Children's Leukemia Group (CCLG)-ALL 2008 regimen and 21 cases were performed by using Chinese Children's Cancer Group (CCCG)-ALL 2015 regimen, and the efficacy and incidence of serious adverse events (SAE) between the two groups compared.Results:Among 1 287 B-ALL patients, 83 patients (6.4%) were TCF3-PBX1-positive. The proportion of patients with initial white blood cell count (WBC)≥50×10 9/L in the TCF3-PBX1-positive group was higher than that in the TCF3-PBX1-negative group, while the proportions of patients with MRD ≥1% on induction chemotherapy day 15 or day 19, and MRD ≥0.01% on induction chemotherapy day 33 or day 46 in the TCF3-PBX1-positive group were lower than those in the TCF3-PBX1-negative group (all P < 0.05). Univariate Cox regression analysis showed that MRD ≥1% on induction chemotherapy day 15 or day 19 and TCF3-PBX1 ≥0.01% on induction chemotherapy day 33 or day 46 were risk factors for OS and EFS (all P < 0.05). Multivariate analysis showed that MRD ≥1% on induction chemotherapy day 15 or day 19 was an independent risk factor for OS ( HR = 10.589, 95% CI 1.903-58.933, P = 0.007) and EFS ( HR = 10.218, 95% CI 2.429-42.980, P = 0.002). TCF3-PBX1≥0.01% on induction chemotherapy day 33 or day 46 was an independent risk factor for EFS ( HR = 6.058, 95% CI 1.463-25.087, P = 0.013) but not for OS ( HR = 3.550, 95% CI 0.736-17.121, P = 0.115). The 10-year EFS and OS rates of the TCF3-PBX1-positive group were 84.6% (95% CI 76.9%-93.1%) and 89.1% (95% CI 82.1%-96.6%), and the differences between the two groups were not statistically significant (both P > 0.05). Among 80 children who received standardized treatment, compared with children who were treated with CCLG-ALL 2008 regimen, the incidence of infection-related SAE was lower in children who were treated with CCCG-ALL 2015 regimen [0 (0/21) vs. 20.3% (12/59), χ2 = 5.22, P = 0.022], but there were no statistical differences in treatment-related mortality, relapse rate, EFS and OS between the two groups (all P > 0.05). Conclusions:Children with TCF3-PBX1-positive B-ALL have a good prognosis, and MRD≥1% at middle stage of induction chemotherapy and TCF3-PBX1≥0.01% at the end of induction chemotherapy may be influencing factors for poor prognosis. CCCG-ALL 2015 regimen can reduce infection-related SAE while achieving good efficacy.

Background::The calcineurin inhibitor (CNI)-based immune maintenance regimen that is commonly used after renal transplantation has greatly improved early graft survival after transplantation; however, the long-term prognosis of grafts has not been significantly improved. The nephrotoxicity of CNI drugs is one of the main risk factors for the poor long-term prognosis of grafts. Sirolimus (SRL) has been employed as an immunosuppressant in clinical practice for over 20 years and has been found to have no nephrotoxic effects on grafts. Presently, the regimen and timing of SRL application after renal transplantation vary, and clinical data are scarce. Multicenter prospective randomized controlled studies are particularly rare. This study aims to investigate the effects of early conversion to a low-dose CNI combined with SRL on the long-term prognosis of renal transplantation.Methods::Patients who receive four weeks of a standard regimen with CNI + mycophenolic acid (MPA) + glucocorticoid after renal transplantation in multiple transplant centers across China will be included in this study. At week 5, after the operation, patients in the experimental group will receive an additional administration of SRL, a reduction in the CNI drug doses, withdrawal of MPA medication, and maintenance of glucocorticoids. In addition, patients in the control group will receive the maintained standard of care. The patients’ vital signs, routine blood tests, routine urine tests, blood biochemistry, serum creatinine, BK virus (BKV)/cytomegalovirus (CMV), and trough concentrations of CNI drugs and SRL at the baseline and weeks 12, 24, 36, 48, 72, and 104 after conversion will be recorded. Patient survival, graft survival, and estimated glomerular filtration rate will be calculated, and concomitant medications and adverse events will also be recorded.Conclusion::The study data will be utilized to evaluate the efficacy and safety of early conversion to low-dose CNIs combined with SRL in renal transplant patients.Trial registration::Chinese Clinical Trial Registry, ChiCTR1800017277.

Klebsiella pneumoniae liver abscess accompanied by metastatic infectious complications was firstly reported in 1986. The pathogen was defined as Hypervirulent K. pneumoniae (hvKp) after a series of studies, which is an evolving pathotype and more virulent than classical K. pneumoniae (cKp). At present, it is difficult to distinguish hvKp and cKp in the clinical microbiology lab, which results in delay in early diagnosis and treatment on hvKp-related infections. Biliary tract diseases after cholangiojejunostomy, biliary interventional therapy and liver transplantation have become common causes of recurrent acute cholangitis. The incidence of bacterial liver abscess is on the rise, especially the infection caused by multidrug-resistant bacteria. This article reviews difficulties in the diagnosis and treatment of bacterial liver abscess.

Purpose: In this article, we aimed to investigate the influences of luteolin on inflammatory injury to cardiomyocytes induced by lipopolysaccharide (LPS). Materials and Methods: H9c2 cells were pretreated with different concentrations of luteolin (10, 20, and 50 μM) for 12 h and then stimulated with 10 μg/mL LPS or no LPS for 6 h. Cell viability was detected by CCK-8 assay. Cell apoptosis was determined by flow cytometry. QRT-PCR and Western blotting were utilized to examine mRNA and protein levels. ELISA was used to determine the levels of monocyte chemoattractant protein-1, tumor necrosis factor-alpha, interleukin (IL)-6, IL-1β, and IL-18 in cell supernatants among different groups of H9c2 cells. Immunofluorescence was applied to evaluate reactive oxygen species formation in H9c2 cells. M-mode images of echocardiography, the ejection fraction test, fractional shortening test, end-systolic volume test, and end-diastolic volume test of mouse heart function were obtained by ultrasonic electrocardiogram. Results: Luteolin could alleviate inflammatory damage and inflammatory factor expression among LPS-induced H9c2 cells. Additionally, we found that luteolin decreased LPS-stimulated inflammatory damage in H9c2 cells by down-regulating NOD-like receptor family pyrin domain containing 3 (Nlrp3). Luteolin also improved myocardial function in mice treated with LPS and reduced myocardial relaxation. Luteolin reversed myocardial histological abnormalities in mice and reduced inflammation and cardiomyocyte apoptosis. Additionally, luteolin inhibited oxidative stress-mediated myocardial and systemic tissue damage in mice. Finally, luteolin reduced LPS-induced inflammatory damage in mouse cardiomyocytes by down-regulating Nlrp3. Conclusion We found that luteolin could reduce inflammatory damage to cardiomyocytes induced by LPS by down-regulating Nlrp3.
