Purpose: The risk stratification of pediatric anaplastic large cell lymphoma (ALCL) has not been standardized. In this study, new risk factors were included to establish a new risk stratification system for ALCL, and its feasibility in clinical practice was explored. Materials and Methods: On the basis of the non-Hodgkin’s lymphoma Berlin–Frankfurt–Munster 95 (NHL-BFM-95) protocol, patients with minimal disseminated disease (MDD), high-risk tumor site (multiple bone, skin, liver, and lung involvement), and small cell/lymphohistiocytic (SC/LH) pathological subtype were enrolled in risk stratification. Patients were treated with a modified NHL-BFM-95 protocol combined with an anaplastic lymphoma kinase inhibitor or vinblastine (VBL). Results: A total of 136 patients were enrolled in this study. The median age was 8.8 years. The 3-year event-free survival (EFS) and overall survival of the entire cohort were 77.7% (95% confidence interval [CI], 69.0% to 83.9%) and 92.3% (95% CI, 86.1% to 95.8%), respectively. The 3-year EFS rates of low-risk group (R1), intermediate-risk group (R2), and high-risk group (R3) patients were 100%, 89.5% (95% CI, 76.5% to 95.5%), and 67.9% (95% CI, 55.4% to 77.6%), respectively. The prognosis of patients with MDD (+), stage IV cancer, SC/LH lymphoma, and high-risk sites was poor, and the 3-year EFS rates were 45.3% (95% CI, 68.6% to 19.0%), 65.7% (95% CI, 47.6% to 78.9%), 55.7% (95% CI, 26.2% to 77.5%), and 70.7% (95% CI, 48.6% to 84.6%), respectively. At the end of follow-up, one of the five patients who received maintenance therapy with VBL relapsed, and seven patients receiving anaplastic lymphoma kinase inhibitor maintenance therapy did not experience relapse. Conclusion This study has confirmed the poor prognostic of MDD (+), high-risk site and SC/LH, but patients with SC/LH lymphoma and MDD (+) at diagnosis still need to receive better treatment (ClinicalTrials.gov number, NCT03971305).

OBJECTIVES: To evaluate the performance of different multi-modality fusion models for predicting radiation-induced oral mucositis (RIOM) following radiotherapy in patients with nasopharyngeal carcinoma (NPC). METHODS: We retrospectively collected the data from 198 patients with locally advanced NPC who experienced RIOM following radiotherapy at the Affiliated Tumor Hospital of Guangzhou Medical University from September, 2022 to February, 2023. Based on oral radiation dose-volume parameters and clinical features of NPC, basic classification models were developed using different combinations of feature selection algorithms and classifiers and integrated using a multi-criterion decision-making (MCDM)-based classifier fusion (MCF) strategy and its variant, the H-MCF model. The basic classification models, MCF model, the H-MCF model with a single modality or multiple modalities and other ensemble classifiers were compared for performances for predicting RIOM by assessing the area under the ROC curve (AUC), accuracy, sensitivity, and specificity. RESULTS: The H-MCF model, which integrated multi-modality features, achieved the highest accuracy for predicting severe RIOM with an AUC of 0.883, accuracy of 0.850, sensitivity of 0.933, and specificity of 0.800. CONCLUSIONS Compared with each of the individual classifiers, the multimodal multi-classifier fusion algorithm combining clinical and dosimetric modalities demonstrates superior performance in predicting the incidence of severe RIOM in NPC patients following radiotherapy.

[Objective]To investigate the effect of GRACE scores on prediction of 30-day cardiovascular adverse events in acute chest pain patients.[Methods]A prospective,observational analysis was conducted in the patients with acute chest pain in Emergency Department(ED)from January 1,2016 through April 1,2016.Data including characteris-tics and GRACE scores were collected.All causes leading to MACE were followed up at 30th day after the onset of acute chest pain.[Results]Among a total of 209 patients presenting with acute chest pain enrolled in this study,110 were male (52.63%)and 99 were female(47.37%).The range of age was 20-98years old,and mean age was(65.28±16.85)years old.During follow-up period,12 patients had MACE,2 patients died in ED,3 patients died in hospital,6 patients died out of hospital,and 1 person was diagnosed with myocardial infarction. When compared with non-MACE group,factors including age,BMI,hospitalized patient number,and number of patients admitted in CCU as well as GRACE scores, were significantly higher in MACE group(P<0.05). The predictive ROC curve area of GRACE scores in 30-day MACE was 0.819(0.735 to 0.902). The optimal sensitivity and specificity were 0.92 and 0.65,respectively. The probability of 30-day cardiovascular adverse events in various GRACE score risk stratification was 0.95%(low-risk),6.67%(medi-um-risk),and 18.92%(high-risk),respectively.[Conclusion]The GRACE score was a useful predictor to the occur-rence of 30-day cardiovascular adverse events in acute chest pain patients.

Objective To investigate the diagnostic value of prenatal ultrasonography and magnatic resonance imaging in the fetal intracranial hemorrhage. Methods The 20 antenatal diagnosed ICH cases was collected from 31 200 prenatal diagnosis units in Guangzhou Women and Children′s Medical Center from July 2012 to June 2014. Maternal characteristics, ultrasound, and magnetic resonance imaging findings, clinical course, and postnatal outcome were reviewed. Results Twenty consecutive cases of fetal ICH were evaluated. All cases were diagnosed at mid or third trimester. Transabdominal ultrasound showed 9 cases of hyper echoic lesions in the lateral ventricle, 2 cases of hypoechonic lesions, 2 cases of irregular mixed echo in the parenchyma, 1 case of hyperechoic cerebellar hemisphere with infarction, and 1 case of abnormal choroid plexus. Seventeen cases were associated with ventriculomegaly, brain compression or brain midline displacement. MRI showed the nodular, patchy or linear low signal on T2WI and high signal on T1WI. Some cases were combined with cortex lesions or abnormal parenchyma. ICH was complicated with other structural abnormalities:1 case of cleft palate, 2 cases of spinal deformity and 3 cases of other cerebral cortical malformations. Prenatal diagnosis results were:2 cases diagnosed as positive cytomegalovirus infection and no chromosome abnormalities found in all cases. The follow up results were:1 case was lost, 16 cases were terminated after prenatal diagnosis. Among the 3 survival cases, 1 case has the neurological complication and the other two were normal till now. Conclusions Fetal intracranial hemorrhage has some image features on ultrasound and magnetic resonance. Ultrasound showed hyper echoic lesions with ventriculomegaly. MRI showed the nodular, patchy or linear low signal on T2WI and high signal on T1WI. MRI may contribute to the accuracy of diagnosis, particularly in bleeding site. The regular ultrasonic monitoring is helpful to improve the detection rate.

To study the link between BRAFV600E status and the expression of BIM gene in papillary thyroid carcinoma( PTC) tissues and to analyze the association of these factors with clinicopathological characteristics. BRAFV600E status was determined by MASA-PCR, and qPCR was applied to detect the expression of BIM gene. Finally, the associations of these factors with clinicopathological characteristics were analysed. The rate of mutant BRAFV600E in PTC was 54. 1% , and the expression of BIM gene was lowered in BRAFV600E positive PTC tissues. Additionally, there was significant association( P < 0. 05) between BRAFV600E positiveness and raised TNM Staging (Ⅲ/ Ⅳ), and lowered BIM expression was significantly associated (P<0. 05) with the tumor size and raised TNM Staging(Ⅲ/ Ⅳ). These findings may help us to know more about the mechanism of PTC and to develop new diagnostic biomarkers or prognostic indicators of PTC.

OBJECTIVETo evaluate the efficacy of specific sublingual immunotherapy (SLIT) with Dermatophagoides farinae drops on children with allergic asthma and allergic rhinitis of the preschool and school-age groups of children and adolescents.

METHODThis study analyzed the efficacy of SLIT in 122 children (aged 3-14 yr) with house dust mites-induced allergic asthma and allergic rhinitis. According to the age, patients were defined as the preschool group ( ≤ 6 years old, n = 59) and school-age group (> 6 years old, n = 63). All children were treated with Dermatophagoides farinae drops for at least 2 years. Clinical observation and follow-up study were conducted during the treatment. Before and after SLIT for half a year, 1 year and 2 years, asthma symptom scores (day and night), rhinitis symptom scores and medication scores were evaluated. The adverse events were assessed during the study.

RESULTAfter SLIT for half a year, 1 year and 2 years, there were no significant differences between the preschool group (0.3 ± 0.5,0.0 ± 0.1,0.0 ± 0.0) and school-age group (0.3 ± 0.4,0.0 ± 0.1,0.0 ± 0.0) in day scores of asthma (Z value was -1.687, -0.613,0.000, all P > 0.05). There were no significant differences between the preschool group (0.2 ± 0.5,0.1 ± 0.3,0.0 ± 0.0) and school-age group (0.2 ± 0.4,0.1 ± 0.3, 0.0 ± 0.0) in night scores of asthma (Z value was -0.496, -0.486,0.000, all P > 0.05). There was no significant differences between the preschool group (1.4 ± 0.9,0.4 ± 0.5,0.1 ± 0.3) and school-age group (1.3 ± 0.9,0.5 ± 0.6,0.2 ± 0.4) in symptom scores of allergic rhinitis (Z value was -0.394, -1.166, -1.075, all P > 0.05). There were no significant differences between the preschool group (1.6 ± 0.8,0.0 ± 0.0,0.0 ± 0.0) and school-age group (1.7 ± 0.7,0.0 ± 0.0,0.0 ± 0.0) in medication scores of allergic rhinitis (Z value was -0.655,0.000,0.000, all P > 0.05). After SLIT for 2 years, most children in the preschool and school-age groups were no longer using asthma controlling medication, with no significant difference between the two groups (Z value was 0.000, P > 0.05). The overall incidence of adverse reactions was only 7%, and there was no significant difference in the incidence of adverse reactions between the two groups (χ(2) = 0.000, P > 0.05). The local adverse events were mild gastrointestinal discomfort and rash, a majority of local adverse events in the preschool group were diarrhea. No severe adverse events happened in the treatment.

CONCLUSIONSLIT with Dermatophagoides farinae drops is safe and effective in children with allergic asthma and allergic rhinitis of the preschool and school-age groups of children and adolescents, which provides evidences for early SLIT intervention of the disease.

Objective Discuss the preventions of complications and nursing characters after split liver transplantation in children. Methods Retrospectively analyze the clinical materials of the two cases of child split liver transplantations operated by our center. Results Acute rejection and simple appendicitis happened in one patient. Both patients had some complications including pleural effusion, neuro-system and psycho-system complications, electrolyte disturbances and etc. No bile leakage and bleeding occurred. They took a favorable turn with treatments. Conclusions There were some differences between children and adults in categories of primary liver diseases, pathophysiologic characters, operation methods and complications of operations. In children, the operations were difficult and the complications were more. The postoperative managements were complicated. Emphasizing observation after operation, finding complication as soon as possible and early treatment could help living through perioperative period.
