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.

Objective To investigate the role and underlying mechanism of activating transcription factor 3(ATF3)in suppressing lipopolysaccharide(LPS)-induced autophagy and inflammatory responses in macrophages.Methods Firstly,the gene expression omnibus(GEO)database was used to analyze ATF3 expression in peripheral blood mononuclear cells(PBMCs)from sepsis patients,and gene set enrichment analysis(GSEA)was performed to identify enriched signaling pathways.Secondly,RAW264.7 macrophages were divided into a blank control group and an LPS-stimulated group(100 ng/mL LPS).Western blotting and immunofluorescence assay were used to detect ATF3 protein expression and observe its subcellular localization,respectively.Lentiviral transduction was used to generate ATF3 knockdown and overexpression cell lines to evaluate their effects on cytokine release and bacterial clearance.Cleavage Under Targets and Tagmentation(CUT&Tag)sequencing was employed to identify downstream target genes transcriptionally regulated by ATF3.Furthermore,the impact of ATF3 knockdown or overexpression on autophagy-related gene 5(ATG5),autophagy-related gene 16-like 1(ATG16L1),and autophagy levels was evaluated.Results GEO analysis revealed that ATF3 expression was significantly elevated in PBMCs from sepsis patients(P<0.01),and GSEA showed significant enrichment of autophagy-related and inflammation-related pathways(P<0.01).In RAW264.7 cells,100 ng/mL LPS stimulation significantly increased ATF3 expression in the nucleus than the blank control group(P<0.01).ATF3 knockdown led to increased secretions of TNF-α and IL-6 and enhanced bacterial clearance of macrophages(P<0.01),whereas ATF3 overexpression significantly suppressed TNF-α and IL-6 releases,and remained bacterial clearance at a low level when compared with the conditions in the negative control(NC)group(P<0.01).CUT&Tag results demonstrated that ATF3 was enriched at the promoter regions of key autophagy genes Atg5 and Atg16l1.Compared with the NC group,ATF3 knockdown significantly up-regulated the protein levels of LC3-II/I,ATG5,and ATG16L1 while decreased p62 expression(P<0.01).Conversely,ATF3 overexpression inhibited the expression of LC3-II/I,ATG5,and ATG16L1(P<0.01),but had no significant effect on p62 level.Conclusion Sepsis induces elevated ATF3 expression in macrophages,and suppresses autophagic activity and down-regulates pro-inflammatory cytokines TNF-α and IL-6,which probably mediated by ATF3 regulating transcription of ATG5 and ATG16L1,suggesting ATF3 as a potential therapeutic target for autophagy-inflammation imbalance.

Objective:To investigate the expression of hippocampal synapse-related proteins including synaptophysin (SYN), postsynaptic density protein 95 (PSD95) and growth-associated protein 43 (GAP43) in rats with epilepsy accompanied by depression.Methods:The 3-month-old female clean grade SD rats were selected for the experiment.Lithium chloride pilocarpine was used to establish an epileptic rat model. Rats with successful epilepsy models were divided into epileptic depressive group (EWD group)and epileptic group with 10 in each group based on whether they were accompanied by depression. Furthermore, ten rats with matched body mass were taken as the depressive group and 10 were taken as control group. As for the depressive group rats, chronic unpredictable mild stress stimulation combined with orphanage was adopted to establish a model of depression.The depressive behaviors of rats were evaluated by body mass, sucrose preference test and open field test. Immunohistochemical staining and Western blot were used to detect the expression of SYN, PSD95 and GAP43 proteins in rat hippocampal tissue. SPSS 17.0 software was used for data statistical analysis, repeated measurement ANOVA was used for behavioral results, one-way ANOVA was used for inter group comparison of protein expression data, and LSD test was used for further pairwise comparison.Results:As for the body mass, there was significant interaction effect between the time and group among the 4 groups ( F=7.33, P<0.01). On the 8th day and the 29th day, the body weight of rats in the EWD group and the depressive group were lower than those in the epilepsy group (all P<0.05). The body weight of rats in the EWD group on the 29th day was lower than that on the first day ( P<0.05). As for the sucrose preference rates, there was significant interaction effect between the time and group among the 4 groups( F=2.67, P<0.05). The sucrose preference rate of EWD group on the15th and 29th day were lower than that on the first day (both P<0.05). The results of the open field test showed that the interaction effects of the number of vertical standing times( F=2.74) and the number of horizontal movement lattices ( F=1.76) both were not significant (both P>0.05), but both the time effect and group effect were significant (vertical standing times: Ftime=4.35, P<0.05, Fgroup=25.64, P<0.01; horizontal movement lattices: Ftime=12.75, P<0.01, Fgroup=21.37, P<0.01). The immunohistochemical results showed that there was a statistically significant difference in the number of positive cells expressing synaptic proteins SYN, PSD95 and GAP43 among the four groups of rats ( F=93.85, 58.66, 98.84, all P<0.05). The numbers of positive cells of SYN (11.73±4.30), PSD95 (24.47±7.58) and GAP43 (9.40±3.50) in the epilepsy group were lower than those in the control group ((51.00±15.39), (55.60±13.17) and (29.53±4.05)) (all P<0.05). The numbers of positive cells of SYN (5.80±3.53), PSD95 (12.87±4.03) and GAP43 (5.33±3.50) in the EWD group were lower than those in the depressive group ((11.33±3.22), (48.13±12.69) and (15.47±5.21) )(all P<0.05). Western blot results showed that there were statistically significant differences in the expression of synaptic proteins SYN, PSD95 and GAP43 among the four groups of rats ( F=13.19, 9.38, 16.80, all P<0.05). The expression levels of SYN, PSD95 and GAP43 in the epilepsy group were lower than those in the control group (all P<0.05). The expression levels of SYN, PSD95 and GAP43 in the EWD group were lower than those in the epilepsy group and the depressive group (all P<0.05). Conclusion:The low expression of SYN, PSD95 and GAP43 proteins in the hippocampus of rats with epilepsy accompanied by depression may be related to their pathogenesis.

Purpose: This study aimed to investigate reproductive concerns among breast cancer patients of reproductive age, analyze the influencing factors, explore the relationship between coping styles, fear of progression (FOP), and reproductive concerns, and identify the multiple effects of coping styles on the relationship between FOP and reproductive concerns among Chinese breast cancer patients. Methods: A cross-sectional, descriptive study was conducted among breast cancer patients in four tertiary grade A hospitals in Fujian, China, from January 2022 to September 2022. A total of 210 patients were recruited to complete paper-based questionnaires, which included the general data questionnaires, the Reproductive Concerns After Cancer Scale (RCACS), the Fear of Progression Questionnaire-Short Form (FOP-Q-SF), and the Medical Coping Modes Questionnaire (MCMQ). Structural equation models were utilized to evaluate the multiple effects of coping styles on FOP and reproductive concerns. Results: Reproductive concerns in breast cancer patients had a mean score of 53.02 (SD, 10.69), out of a total score of 90, and coping styles for cancer (confrontation, avoidance) were closely associated with FOP and reproductive concerns. FOP showed a significant positive correlation with reproductive concerns (r = .52, p < .01). At the same time, confrontation was significantly negatively correlated with both FOP (r = −.28, p < .01) and reproductive concerns (r = −.39, p < .01). Avoidance was positively correlated to both FOP (r = .25, p < .01) and reproductive concerns (r = .34, p < .01). The impact of FOP on reproductive concerns is partially mediated by confrontation and avoidance, with effect sizes of .07 and .04, respectively. These mediating factors account for 22.0% of the total effect. Conclusions The FOP directly impacted reproductive concerns, while coping styles could partially mediate the association between FOP and reproductive concerns. This study illustrates the role of confrontation and avoidance in alleviating reproductive concerns, suggesting that it is necessary to focus on the changes in reproductive concerns among reproductive-age breast cancer patients. Healthcare professionals can improve disease awareness and reduce patients' FOP, thereby promoting positive psychological and coping behaviors and ultimately alleviating reproductive concerns.

Objective:To investigate the clinicopathologic characteristics, gene mutation profile and prognostic influencing factors of diffuse large B-cell lymphoma (DLBCL) complicated with follicular lymphoma (FL) (DLBCL/FL).Methods:The clinicopathological data of 50 DLBCL/FL patients admitted to Rui Jin Hospital Affiliated of Shanghai Jiao Tong University School of Medicine from February 2018 to November 2021 were retrospectively analyzed. Targeted sequencing was performed to assess the mutation profile of 55 lymphoma-related genes. The clinicopathological characteristics were summarized to evaluate the short-term therapeutic efficacy of all patients. Kaplan-Meier method was used to analyze the overall survival (OS) and progression-free survival (PFS) of patients. Cox regression risk models were used to assess the factors affecting the OS and PFS.Results:Among 50 DLBCL/FL patients, 23 cases (46%) were male, 22 cases (44%) had an international prognosis index (IPI) score ≥ 2 points, 16 cases (32%) were double-expression lymphoma (DEL) and 4 cases (8%) were double-hit lymphoma (DHL). The complete response (CR) and overall response rates were 68% (34/50) and 78% (39/50), respectively after the first-line therapy. The median follow-up time was 23.3 months (5.1-50.9 months). The 2-year OS rate was 82.1% and 2-year PFS rate was 67.1%; and the median OS and PFS were not reached. Targeted sequencing results showed that the mutation frequencies of KMT2D, MYD88, TP53, BTG2, DTX1, EZH2, CD70, CREBBP, DUSP2, HIST1H1C, HIST1H1E and PRDM1 genes in this cohort were more than 15%. Multivariate Cox regression analysis showed that male ( HR = 4.264, 95% CI 1.144-15.896, P = 0.031) and IPI score ≥ 2 points ( HR = 6.800, 95% CI 1.771-37.741, P = 0.007) were independent risk factors of PFS in newly diagnosed DLBCL/FL patients, and TP53 mutation ( HR = 4.992, 95% CI 1.027-24.258, P = 0.046) was an risk influencing factor of OS. Conclusions:The proportion of male and female DLBCL/FL patients is similar, with a small proportion of DHL. Mutations of KMT2D, MYD88 and TP53 genes are commonly found in DLBCL/FL patients. Generally, DLBCL/FL patients can have a high overall response and good prognosis. Male and IPI score ≥ 2 points are the independent risk factors of PFS, and TP53 mutation is an independent risk factor of OS in DLBCL/FL patients.

At present, the routine specialized training for primary pediatricians (focusing on theoretical learning of public subjects) cannot meet the needs of primary pediatricians. In order to promote the development of children's medical care at the grassroots level and improve the quality, medical and clinical research abilities of regional pediatric medical personnel, the Children's Hospital of Chongqing Medical University has designed and built a "hierarchical training model for improving the professional ability of pediatricians" from the aspects of training objectives, training contents, training methods, construction and evaluation of training programs, and quality control. In addition, the 8-month "Pediatric Professional Basic Training" and the 9-month "Pediatric Professional Ability Improvement Training" were respectively carried out in Xianyang Children's Hospital. In the "Professional Basic Training", 88 trainees were comprehensively evaluated after training, 53 of whom were qualified or above. In the "Ability Improvement Training", 26 of the 29 students actually participated in the evaluation and reached the qualified level or above. Learners provided feedbacks that they have effectively improved their own knowledge structure, expanded their clinical diagnosis and treatment thinking and clinical research ideas, and provided some guidance for clinical work.

Objective:To report 2 young infants of sodium channel related epilepsy with SCN2A gene mutation, and to discuss the clinical characteristics of the disease and the efficacy and safety of lacosamide combined with the literature.Methods:Corresponding information of 2 children hospitalized in the Department of Neurology of Hunan Children′s Hospital in July 2021 and October 2021 was collected, including the symptoms, comprehensive physical examination, blood, cerebrospinal fluid, imaging, electrophysiological examination, diagnosis and treatment process, response to treatment and other clinical data, as well as the sequencing results of the whole exome of the children. The efficacy and safety of lacosamide were analyzed, and the related literatures of the Biomedical Literature Database, Wanfang Data Knowledge Service Platform and Chinese Knowledge Infrastructure Database were searched and reviewed.Results:Both of the 2 cases were girl. Their onset age was within 3 months. The initial symptoms were frequent convulsions and backward development. There was no structural abnormality in the head image. The convulsions could not be controlled according to conventional multidrug treatment. The seizures were quickly controlled with lacosamide. Now they have been followed up for 6 months. No obvious adverse reactions were found. Case 1 gene test results showed the SCN2A gene (chr2:166152333-166246334) heterozygous deletion, SCN1A gene (chr2:166847754-16693013) heterozygous deletion, the deletion size being about 5.72 Mb. Case 2 gene test results showed new missense mutation of SCN2A (c.1285G>A, p.Glu429Lys). There were dozens of seizures every day. They were treated with valproic acid, oxcarbazepine and levetiracetam successively. The seizures could not be controlled. Three focal seizures originated in the left temporal region were detected by electroencephalogram. There was no recurrence on the third day after adding lacosamide, and there was no attack after 5 months of follow-up. No obvious adverse reactions were found during follow-up.Conclusions:Sodium channel related epileptic encephalopathy often starts early, has frequent seizures, and can be accompanied by backward psychomotor development at the same time. The slow sodium channel blocker lacosamide has good efficacy and safety in the treatment of sodium channel-related epilepsy with SCN2A gene mutation or combined SCN1A gene mutation.
