Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Lysine methyltransferase 2A( KMT2A) rearrangement (KMT2A-r) is a high-risk gene subtype of acute lymphoblastic leukemia (ALL) in children with a high relapse rate, poor prognosis and suboptimal response to conventional chemotherapy.Improving the treatment and prognosis of childhood KMT2A-r ALL is an urgent problem.In recent years, with an in-depth understanding of the mechanism of KMT2A-r, more accurate risk stratification of KMT2A-r ALL has been carried out, and great progress has also been made in its immune and targeted therapy.In this article, the genetic and biological characteristics, risk stratification, treatment strategies and prognosis of children KMT2A-r ALL were reviewed in order to provide theoretical support for clinical work and future research.

The incidence of early-onset gastric cancer (EOGC) is consistently increasing, and its etiology is notably complex. This increase may be attributed to distinctive factors that differ from those associated with late-onset gastric cancer (LOGC), including genetic predispositions, dietary factors, gastric microbiota dysbiosis, and screening of high-risk cases. These factors collectively contribute to the onset of cancer. EOGC significantly differs from LOGC in terms of clinicopathological and molecular characteristics. Moreover, multiple differences in prognosis and clinical management also exist. This study aimed to systematically review the latest research advancements in the epidemiological characteristics, etiological factors, clinicopathological and molecular features, prognosis, and treatment modalities of EOGC.

Objective:To construct a diagnostic model for fatty liver using body composition analysis and further evaluate the diagnostic effect of the model on fatty liver.Methods:726 cases with chronic liver disease who visited Tianjin Second People's Hospital from April 2019 to June 2022 and had body composition analysis tests were retrospectively enrolled and were divided into a fatty liver group (551 cases with fatty liver) and a control group (175 cases without fatty liver) according to the measured values of abdominal ultrasound and controlled attenuation parameter. An independent sample t-test and a non-parametric rank sum test were used for statistical processing. Logistic regression was used to construct a diagnostic model. Hosmer-Lemeshow was used to validate the fit of model. Receiver operating characteristic curve was used to confirm the diagnostic efficiency of the model. In addition, 341 cases of chronic liver disease who visited Tianjin Second People's Hospital were included to further verify the application effect of the model between July 2022 and February 2023.Results:Compared with the control group, the differences in various indicators of body composition analysis in the fatty liver group were statistically significant ( P < 0.05). Basal metabolic rate (X1), visceral fat area (X2), and body fat (X3) were eventually included in the diagnostic model for BCA-FL (body composition analysis-fatty liver)= -7.771+0.002X1-0.035X2+0.456X3 with the Hosmer-Lemeshow test (P=0.059). The measured area under the receiver operating characteristic curve, the sensitivity, and the specificity were 0.888, 0.889, and 0.726, respectively, when the diagnostic threshold value was 0.615 with the Youden index and the receiver operating characteristic curve. In the validated model group, the area under the receiver operating characteristic curve, Youden index, sensitivity, and specificity were 0.875, 0.624, 0.799, and 0.825, respectively. Conclusion:The diagnostic model BCA-FL for fatty liver constructed using human body composition analysis has good diagnostic efficacy and is suitable for screening fatty liver in different basic liver disease populations.

Background::The role of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with high-risk (HR) T-cell acute lymphoblastic leukemia (T-ALL) in first complete remission (CR1) is still under evaluation. Moreover, relapse is the main factor affecting survival. This study aimed to explore the effect of allo-HSCT (especially haploidentical HSCT [haplo-HSCT]) on improving survival and reducing relapse for HR childhood T-ALL in CR1 and the prognostic factors of childhood T-ALL in order to identify who could benefit from HSCT.Methods::A total of 74 newly diagnosed pediatric T-ALL patients between January 1, 2012 and June 30, 2018 were enrolled in this retrospective study. Patients were stratified into the low-risk chemotherapy cohort ( n = 16), HR chemotherapy cohort ( n = 31), and HR transplant cohort ( n = 27). Characteristics, survival outcomes, and prognostic factors of all patients were then analyzed. Results::Patient prognosis in the HR chemotherapy cohort was significantly worse than that in the low-risk chemotherapy cohort (5-year overall survival [OS]: 58.5% vs. 100%, P = 0.003; 5-year event-free survival [EFS]: 54.1% vs. 83.4%, P = 0.010; 5-year cumulative incidence of relapse [CIR]: 45.2% vs. 6.3%, P = 0.011). In HR patients, allo-HSCT improved the 5-year EFS and CIR compared to that of chemotherapy (5-year EFS: 80.1% vs. 54.1%, P = 0.041; 5-year CIR: 11.6% vs. 45.2%, P = 0.006). The 5-year OS was higher in the HR transplant cohort than that in the HR chemotherapy cohort (81.0% vs. 58.5%, P = 0.084). Minimal residual disease re-emergence was an independent risk factor for 5-year OS, EFS, and CIR; age ≥10 years was an independent risk factor for OS and EFS; and high white blood cell count was an independent risk factor for EFS and CIR. Conclusion::Allo-HSCT, especially haplo-HSCT, could effectively reduce relapse of children with HR T-ALL in CR1.

Objective:To evaluate three-stage induced membrane technique combined with anterior and posterior double-plate fixation in the treatment of a total talus defect after infection.Methods:Included in this study were 11 patients with talus infection who had been treated at Department of Orthopaedics, Foshan Hospital of Traditional Chinese Medicine from January 2014 to December 2018. They were 8 males and 3 females, aged from 23 to 63 years (mean, 37.0 years). The infection followed re-implantation after open dislocation of total talus in 4 cases, internal fixation for open talus fracture of Gustilo type Ⅲa in 3 cases and surgery of open ankle fracture of Gustilo type Ⅲc in 2 cases, and was complicated with ankle intraarticular tuberculosis in 2 cases. The three-stage operations consisted of debridement, total talus resection, implantation of antibiotic bone cement and vacuum sealing drainage at the first stage, change of bone cement, re-debridement, wound closure or flap covering at the second stage 7 to 10 days later, and reconstruction after infection control using anterior and posterior double-plate fixation and induced membrane technique at the third stage 6 to 12 weeks later. Assessment of lower limb shortening was performed by comparing the full length of the leg between the normal and affected sides; the functions were assessed by comparing the ankle-hindfoot scores of American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS) between preoperation and the final follow-up.Results:The 11 patients were followed up for an average of 24.3 months (from 12.2 to 37.5 months). Superficial skin necrosis was observed in 2 patients and injury to superficial peroneal nerve in one. Absolute calcification of the autograft area was observed in all patients, leading to ankle fusion. The final follow-ups observed no significant difference in the full length of the leg between the normal and affected sides [(380.4±35.5) mm versus (376.3±32.8) mm] ( P>0.05) , a significant increase in the ankle-hindfoot AOFAS scores from preoperative 28.0±3.4 to 72.8±5.4, and a significant decrease in VAS scores from preoperative 5(5,6) to 0(0,1) (all P<0.05). Slight varus developed in 2 patients and slight ankle stiffness in 3; recurrence of infection or breakage of implants was found in none of the patients. Conclusion:Three-stage induced membrane technique combined with anterior and posterior double-plate fixation can effectively control infection of the talus, maintain the length and reconstruct the function of the lower limb after a total talus defect.
