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.

Objectives:To evaluate the predictive value of Tabular Prior-data Fitted Network(TabPFN) for short-term outcome in patients with spontaneous intracerebral hemorrhage (sICH), and compared with the Extreme Gradient Boosting (XGboost) model and traditional logistic regression (LR) model. Methods:Patients with sICH admitted to the Department of Neurology, Hefei Second People's Hospital from January 2018 to March 2024 were included retrospectively. The demographic and baseline data were collected. At 3 months after onset, the modified Rankin Scale score was used to determine the outcome, 0-2 was defined as good outcome and >2 was defined as poor outcome. All enrolled patients were randomly divided into a training set and a testing set at a ratio of 7:3. Feature selection was performed using recursive feature elimination (RFE) method, and then the selected feature variables were included into TabPFN, XGboost, and LR models for training and testing. The area under the curve (AUC) of receiver operating characteristic (ROC) curve was used to evaluate the predictive ability of the models. Shapley additive explanations (SHAP) method was used for model interpretation.Results:A total of 547 patients with sICH were enrolled, including 367 males (67.1%), with a median age of 65 (interquartile range, 54-76) years. Two hundred twenty-six patients (41.3%) had poor outcome. Age, baseline blood pressure (systolic blood pressure, diastolic blood pressure), baseline laboratory tests (white blood cell count, red blood cell count, platelet count, neutrophil count, hemoglobin, fasting blood glucose, creatinine, uric acid, urea nitrogen, alanine aminotransferase, aspartate aminotransferase), hematoma rupture into the ventricle, island sign, baseline hematoma volume, and baseline National Institutes of Health Stroke Scale (NIHSS) score were selected as characteristic variables using RFE method. ROC curve analysis showed that the ROC AUC for TabPFN, Xgboost, and LR models predicting poor short-term outcome in the testing set were 0.918 (95% confidence interval [ CI] 0.870-0.966], 0.883 (95% CI 0.826-0.940), and 0.905 (95% CI 0.854-0.957), respectively. SHAP analysis showed that the top four important variables in the TabPFN model were baseline NIHSS score, baseline hematoma volume, baseline aspartate aminotransferase, and age. Conclusions:The TabPFN model is superior to the LR model and the XGBoost model in predicting poor outcome in patients with sICH. In the TabPFN model, baseline NIHSS score, baseline hematoma volume, aspartate aminotransferase, and age are the most important predictors of poor outcome in patients with sICH.Objectives To evaluate the predictive value of Tabular Prior-data Fitted Network(TabPFN) for short-term outcome in patients with spontaneous intracerebral hemorrhage (sICH), and compared with the Extreme Gradient Boosting (XGboost) model and traditional logistic regression (LR) model.

Objective To explore the impact of family sandplay therapy based on the narrative concept on family resilience and sense of meaning in life among gastric cancer patients.Methods A total of 104 gastric cancer patients were selected and randomly divided into control group and experi-mental group,with 52 patients in each group.The control group received routine nursing care,while the experimental group received family sandplay therapy based on the narrative concept in addition to routine nursing care.Both groups were assessed using the Chinese Family Resilience Assessment Scale(C-FRAS)and the Chinese Meaning in Life Questionnaire(C-MLQ)before the intervention and at 1 month and 3 months post-intervention.The scores of scales were compared.Results After interven-tion,the total C-FRAS score and score of each dimension were higher in the experimental group than those in the control group,and both the total C-FRAS score and score of each dimension showed an upward with time extension.The total C-MLQ score and score of each dimension were also higher in the experimental group compared with the control group(P＜0.05).Conclusion Family sandplay therapy based on the narrative concept can enhance family resilience and sense of meaning in life a-mong gastric cancer patients.

Objective To analyze the impact of patients ages on propofol dosage in painless gastroscopy.Methods A retrospective analysis was conducted on the clinical data of 158 painless gastroscopy patients from January 2017 to June 2020.They were divided into the young group(18～44 years old,n = 57),the middle-aged group(45～59 years old,n = 51),and the elderly group(≥60 years old,n = 50)based on their age.The anesthesia status and safety of each group were compared.Results The results showed that the dosage of propofol,average total dosage of propofol,MAP,HR,RR,SpO2 levels in the young group were higher than those in the middle-aged and elderly groups when consciousness disappeared,and the middle-aged group was higher than the elderly group;The onset time,anesthesia recovery time,orientation recovery time,and departure time in the young group of patients were shorter than those in the middle-aged and elderly groups,and the middle-aged group was shorter than the elderly group(P<0.05).The incidence of airway obstruction,hypoxemia,mandible support,mask ventilation,adverse cardiovascular events,sedation related adverse events,and incidence of obstructed endoscopy in the elderly group were higher than those in the young and middle-aged groups.The incidence of smooth endoscopy was lower than that in the young and middle-aged groups(P<0.05).Conclusion Aging may increase the dosage of propofol in patients underwent painless gastroscopy under anesthesia,prolong the onset time,anesthesia recovery time,orientation recovery time,and departure time,increase stress reactions and adverse reactions,and strengthen monitoring for elderly patients in clinical practice.

Objective:To analyze the clinical data of histiocytic necrotizing lymphadenitis(HNL),comparing the similarities and differences between children and adults,to deepen the understanding of the disease by clinical physicians,and to improve diagnostic rate and reduce misdiagnosis and mistreat-ment.Methods:The clinical data of hospitalized patients with histiocytic necrotizing lymphadenitis diagnosed by biopsy from January 2010 to August 2023 in Peking University First Hospital were collec-ted,and the clinical features,laboratory examinations,pathological features,treatments with antibiotics and glucocorticoids,and prognosis of histiocytic necrotic lymphadenitis were analyzed.Grouped based on age,the differences of clinical characteristics,laboratory tests,treatment,and prognosis between the children group(＜16 years old)and the adult group(≥16 years old)were compared.Results:Among the 81 enrolled patients,there were 42 males and 39 females.The median age was 21(14,29)years,the median duration of disease was 20.0(13.0,30.0)days,and the median length of hospital stay was 13.0(10.0,15.0)days.The first symptoms were fever,lymphadenopathy,and both.All the patients had enlarged lymph nodes with different parts and sizes,96.3％(78 of 81)of the patients had cervical lymphadenopathy,50.6％(41 of 81)had bilateral cervical lymphadenopathy,55.6％(45 of 81)had supraclavicular,axillary or inguinal lymphadenopathy,and the median lymph node diameter was 20.0(20.0,30.0)mm.Only one patient had no fever,the other 80 patients had fever,the median peak body temperature was 39.0(38.0,39.8)℃.Accompanying symptoms:rash(8.6％,7/81),fatigue(34.6％,28/81),night sweating(8.6％,7/81),chills(25.3％,25/81),muscle soreness(13.6％,11/81),and joint pain(6.2％,5/81).There were 17 cases(21.0％,17/81)of hepatosplenomegaly,of which 12 cases(70.6％,12/17)were splenomegaly.68.8％(55/80)of patients had a decrease in white blood cell(WBC)count,with 47.5％(38/80)increased in lymphocyte(LY)proportion,53.4％(39/73)increased in high-sensitivity C-reactive protein(CRP),79.2％(57/72)increased in erythrocyte sedimentation rate(ESR),22.2％(18/81)increased in alanine transaminase(ALT),27.2％(22/81)elevated in aspartate transaminase(AST),and 81.6％(62/76)elevated in lactate dehydrogenase(LDH).All the 81 patients underwent lymph node biopsy,and 77.8％(63/81)of the patients showed that most of the structures in the lymph nodes were destroyed or disappeared,and 16.0％(13/81)of the lymph nodes were still in existence,hyperplasia and normal lymph node were 1.2％(1/81)respectively,and 3.7％(3/81)had normal lymph node structures.Immunohistochemical staining was performed in 67 cases.The percentages of CD3+and CD68(KP1)+were respectively 97.0％(65/67),and MPO+were 94.0％(63/67).In the study,51 patients(63.0％,51/81)were treated with glucocorticoid therapy after diagnosis.The median time for temperature to return to normal was 1.0(1.0,4.0)days after glu-cocorticoid therapy.when the glucocorticoid treatment worked best,the body temperature could drop to normal on the same day.There were significant differences in length of stay,predisposing factors,chills,the rate of increase in high-sensitivity CRP,antibiotic and glucocorticoid treatment between the adults and children groups(P＜0.05).Conclusion:In clinical practice,if there are cases with unexplained fever,su-perficial lymph node enlargement,and reduced white blood cells as clinical characteristics,and general anti-biotics treatment is ineffective,histiocytic necrotic lymphadenitis should be considered.Lymph node biopsy should be performed as early as possible to clarify the diagnosis,reduce misdiagnosis and mistreatment,and symptomatic treatment should be the main treatment.Glucocorticoids therapy has a definite therapeutic effect.

Objective:To learn about the operation of fluoride reduction and water improvement projects, the current situation of water fluoride level and the changing trend of fluorosis in drinking water-borne endemic fluorosis areas in Shaanxi Province, and to evaluate the effect of prevention and control measures.Methods:From March 2014 to December 2021, 15 endemic villages in drinking water-borne endemic fluorosis areas of Dali, Dingbian, Jingbian, Jingyang and Liquan counties in Shaanxi Province were selected as monitoring villages to investigate the operation of water improvement projects. Water samples were collected, and the water fluoride level was detected according to the "Standard Examination Methods for Drinking Water - Nonmetal Parameters" (GB/T 5750.5-2006). "Diagnosis of Dental Fluorosis" (WS/T 208-2011) was done to detect dental fluorosis in all children aged 8 - 12 who were born and lived in the monitoring village. Using "Diagnostic Standard for Endemic Skeletal Fluorosis" (WS/T 192-2008) and "Determination of Fluoride in Urine - Ion Selective Electrode Method" (WS/T 89-2015), X-ray examination and urine fluoride level test were performed on adults over 25 years old who had lived in the monitoring village for more than 5 years, respectively.Results:From 2014 to 2021, a total of 122 water improvement projects were investigated, all of which were in normal operation. The qualified rate of water fluoride increased from 81.25% (13/16) in 2014 to 100.00% (11/11) in 2021. A total of 5 595 children aged 8 - 12 were examined, 1 790 children with dental fluorosis were detected, with a detection rate of 31.99%. The detection rate of dental fluorosis in children decreased from 52.05% (304/584) in 2014 to 9.68% (93/961) in 2021, showing an overall downward trend (χ 2trend = 533.76, P < 0.001). In 2014, 791 adults were examined, and 256 patients with skeletal fluorosis were detected, the detection rate was 32.36%. In 2019, 770 adults were examined, and 88 patients with skeletal fluorosis were detected, with a detection rate of 11.43%. The detection rate of skeletal fluorosis in adults in 2019 was lower than that in 2014, and the difference was statistically significant (χ 2 = 99.54, P < 0.001). In 2014, 754 adult urine samples were collected, and the geometric mean of urine fluoride was 2.571 mg/L. In 2019, 770 adult urine samples were collected, and the geometric mean of urine fluoride was 1.292 mg/L. The geometric mean of urine fluoride in adults in 2019 was lower than that in 2014, and the difference was statistically significant ( Z = - 12.74, P < 0.001). Conclusions:From 2014 to 2021, the water improvement projects in drinking water-borne endemic fluorosis areas in Shaanxi Province are running normally, and the qualified rate of water fluoride has increased. The incidence of dental fluorosis in children and skeletal fluorosis in adults has decreased. In the later stage, it is necessary to continuously strengthen the monitoring and management of water improvement projects to prevent the rebound of water fluoride from causing residents' illness.

Objective: To investigate the current situation of hearing health among college students and associated factors, and to provide a basis for universities and relevant departments to carry out hearing health work. Methods: By using stratified random sampling method, 1306 students from 4 universities in Taiyuan were screened for hearing loss and were investigated with a questionnaire from March to November 2021. Data were analyzed by using the SPSS 19.0 statistical. Results: The detection rate of hearing loss was 31.70%. The majority (51.91%) failed to pass the 4 000 Hz hearing screening. The total awareness rate of hearing problems was 58.96%. Logistic regression analysis showed that the total daily usage time of earphones >4 h/d, the duration of using earphones >1 h/time were positively correlated with positive screening for hearing loss among college students( OR=1.23, 1.14, P < 0.01), and good awareness of hearing health care and highest education of parents were negatively correlated with positive screening for hearing loss among coollege students( OR =0.54, 0.76, 0.37, P <0.05). Conclusion The awareness of hearing health care among college students is low. Universities and relevant departments should take targeted measures to provide the best hearing health care services.

Purpose: To analyze the gene mutation, immune infiltration and tumor growth of primary tumor and distant tumor under different treatment modes. Materials and Methods: Twenty B16 murine melanoma cells were injected subcutaneously into the of both sides of the thigh, simulating a primary tumor and a secondary tumor impacted by the abscopal effect, respectively. They were divided into blank control group, immunotherapy group, radiotherapy group, and radiotherapy combined immunotherapy group. During this period, tumor volume was measured, and RNA sequencing was performed on tumor samples after the test. R software was used to analyze differentially expressed genes, functional enrichment, and immune infiltration. Results: We found that any treatment mode could cause changes in differentially expressed genes, especially the combination treatment. The different therapeutic effects might be caused by gene expression. In addition, the proportions of infiltrating immune cells in the irradiated and abscopal tumors were different. In the combination treatment group, T-cell infiltration in the irradiated site was the most obvious. In the immunotherapy group, CD8+ T-cell infiltration in the abscopal tumor site was obvious, but immunotherapy alone might have a poor prognosis. Whether the irradiated or abscopal tumor was evaluated, radiotherapy combined with anti-programmed cell death protein 1 (anti-PD-1) therapy produced the most obvious tumor control and might have a positive impact on prognosis. Conclusion Combination therapy not only improves the immune microenvironment but may also have a positive impact on prognosis.

OBJECTIVES: Diabetic kidney disease is one of the most serious complications of diabetes mellitus (DM), and it is a main cause for chronic kidney disease and end-stage kidney disease (ESRD). It is important to find out the factors that cause the progression of renal function. The study aims to explore the relationship between serum uric acid (SUA) trajectory and the progression of renal function in patients with Type 2 diabetes mellitus (T2DM). METHODS: A total of 846 patients with T2DM, who were admitted to the Department of Nephrology and Endocrinology, the Third Xiangya Hospital of Central South University, from January 2009 to December 2021 and met the criteria of baseline estimated glomerular filtration rate (eGFR)≥60 mL/(min·1.73 m²), were selected as the research subjects. The SUA data of multiple measurements were collected and identified as different SUA trajectories by group-based trajectory modeling (GBTM). According to the SUA trajectories, the patients were divided into a low trajectory group (105 cases), a middle trajectory group (396 cases), a middle high trajectory group (278 cases), and a high trajectory group (67 cases). Cox regression analysis was used to examine the effect of SUA trajectory on the progression of renal function in patients with T2DM. Subgroup analysis was performed by sex, age, course of disease, body mass index (BMI) and hemoglobin A1c (HbA1c). RESULTS: The median follow-up was 4.8 years. At the end of follow-up, 158 patients had different degrees of decline in renal function. After adjusting for multiple confounding factors by Cox regression analysis, the risks of eGFR<60 mL/(min·1.73 m²), eGFR reduction rate≥50%, serum creatinine (Scr) doubling and composite endpoint (eGFR reduction rate≥50%, Scr doubling or ESRD) in the high trajectory group were significantly higher than those in the low trajectory group, with HR of 3.84 (95% CI 1.83 to 8.05), 6.90 (95% CI 2.27 to 20.96), 6.29 (95% CI 2.03 to 19.52), and 8.04 (95% CI 2.68 to 24.18), respectively. There was no significant difference in the risk of ESRD among the above 4 groups (all P>0.05). Subgroup analysis showed that: compared with the low trajectory group, the risks of eGFR<60 mL/(min·1.73 m²) in patients with high trajectory in the subgroup of male, female, age<65 years, course of disease<10 years, BMI≥24 kg/m² and HbA1c≥7% were increased (all P<0.05). The SUA trajectory had no interaction with sex, age, course of disease, BMI and HbA1c (all interactive P>0.05). CONCLUSIONS The high SUA trajectory increases the risk for progression of renal function in patients with T2DM. Long-term longitudinal changes of SUA should be paid attention to.

The hemodynamics of children with congenital heart disease (CHD) often changes during the perioperative period. Unfortunately, the evaluation of cardiac function in children with CHD is mainly focused on the left ventricle. With the further understanding of cardiac hemodynamics, the monitoring of RV function has gradually become an important part of cardiac intensive care department. We totally searched five databases including Pubmed, Embase, Cochrane, Wanfang Med, as well as China National Knowledge Infrastructure (CNKI) and reviewed the clinical research progress of the application of TAPSE in the evaluation of RV systolic function in children with CHD to provide a theoretical basic for the monitoring of RV function before and after operation in children with CHD.
