ObjectiveTo investigate the value of intestinal fatty acid-binding protein （I-FABP） in predicting 6-week mortality in patients with liver cirrhosis after successful endoscopic hemostasis for esophagogastric variceal bleeding （EVB）. MethodsA retrospective analysis was performed for the clinical data of 207 patients with liver cirrhosis who underwent successful endoscopic treatment for EVB （including ligation and sclerotherapy） in The Affiliated Hospital of Yanbian University from September 2020 to June 2025， with the endpoint of 6-week bleeding-related mortality. ELISA was used to measure the serum level of I-FABP on admission， and a stratified analysis was performed based on the quartiles of I-FABP measurements. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier survival analysis， Cox regression analysis， and restricted cubic spline （RCS） curve were used to investigate the association between I-FABP and mortality. Machine learning models were used to further quantify the impact of I-FABP on mortality. The integrated Brier score and an integrated cumulative/dynamic area under the curve were used to assess the importance of time-dependent variables， and the receiver operating characteristic （ROC） curve was used to assess the performance of the predictive model. ResultsDuring the study， 29 patients （14.0%） died within 6 weeks after successful endoscopic hemostasis， with a median time to death of 16 （8—26） days. The mortality group had a significantly higher serum level of I-FABP than the survival group （Z=-3.731， P<0.001）. The Kaplan-Meier survival analysis showed that there was a significant difference in 6-week mortality between the groups of patients based on I-FABP quartiles （χ²=12.78， P=0.005）. The multivariable Cox regression analysis showed that an increase in I-FABP （hazard ratio=1.87， P=0.003） was an independent influencing factor for 6-week mortality. The RCS analysis showed a linear relationship between I-FABP and 6-week mortality （P_non-linear=0.280， P_overall=0.029）. Machine learning models showed that there was a dynamic change in the importance of I-FABP over time， and Brier score loss and the loss of cumulative/dynamic area under the curve after permutation showed that I-FABP was an important variable affecting 6-week mortality rate. ConclusionI-FABP level is independently associated with the risk of 6-week mortality endoscopic hemostasis for EVB in patients with liver cirrhosis， and therefore， it can be used as a potential biomarker for poor short-term prognosis.

Instrument separation is a critical complication during root canal therapy, impacting treatment success and long-term tooth preservation. The etiology of instrument separation is multifactorial, involving the intricate anatomy of the root canal system, instrument-related factors, and instrumentation techniques. Instrument separation can hinder thorough cleaning, shaping, and obturation of the root canal, posing challenges to successful treatment outcomes. Although retrieval of separated instrument is often feasible, it carries risks including perforation, excessive removal of tooth structure and root fractures. Effective management of separated instruments requires a comprehensive understanding of the contributing factors, meticulous preoperative assessment, and precise evaluation of the retrieval difficulty. The application of appropriate retrieval techniques is essential to minimize complications and optimize clinical outcomes. The current manuscript provides a framework for understanding the causes, risk factors, and clinical management principles of instrument separation. By integrating effective strategies, endodontists can enhance decision-making, improve endodontic treatment success and ensure the preservation of natural dentition.

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.

Periodontal bone defects, primarily caused by periodontitis, are highly prevalent in clinical settings and manifest as bone fenestration, dehiscence, or attachment loss, presenting a significant challenge to oral health. In regenerative medicine, harnessing developmental principles for tissue repair offers promising therapeutic potential. Of particular interest is the condensation of progenitor cells, an essential event in organogenesis that has inspired clinically effective cell aggregation approaches in dental regeneration. However, the precise cellular coordination mechanisms during condensation and regeneration remain elusive. Here, taking the tooth as a model organ, we employed single-cell RNA sequencing to dissect the cellular composition and heterogeneity of human dental follicle and dental papilla, revealing a distinct Platelet-derived growth factor receptor alpha (PDGFRA) mesenchymal stem/stromal cell (MSC) population with remarkable odontogenic potential. Interestingly, a reciprocal paracrine interaction between PDGFRA⁺ dental follicle stem cells (DFSCs) and CD31⁺ Endomucin⁺ endothelial cells (ECs) was mediated by Vascular endothelial growth factor A (VEGFA) and Platelet-derived growth factor subunit BB (PDGFBB). This crosstalk not only maintains the functionality of PDGFRA⁺ DFSCs but also drives specialized angiogenesis. In vivo periodontal bone regeneration experiments further reveal that communication between PDGFRA⁺ DFSC aggregates and recipient ECs is essential for effective angiogenic-osteogenic coupling and rapid tissue repair. Collectively, our results unravel the importance of MSC-EC crosstalk mediated by the VEGFA and PDGFBB-PDGFRA reciprocal signaling in orchestrating angiogenesis and osteogenesis. These findings not only establish a framework for deciphering and promoting periodontal bone regeneration in potential clinical applications but also offer insights for future therapeutic strategies in dental or broader regenerative medicine.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

BACKGROUND:Cervical disc herniation can cause pain in the neck and shoulder area,as well as radiating pain in the upper limbs.The incidence rate is increasing year by year and tends to affect younger individuals.Fully understanding the biomechanical characteristics of the cervical spine in adolescents is of great significance for preventing and delaying the onset of cervical disc herniation in this age group. OBJECTIVE:To reconstruct cervical spine models for both healthy adolescents and adolescent patients with cervical disc herniation utilizing finite element analysis techniques,to analyze the motion range of the C1-T1 cervical vertebrae as well as the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and the cartilage of the small joints. METHODS:A normal adolescent's cervical spine and an adolescent patient with cervical disc herniation were selected in this study.The continuous scan cervical spine CT raw image data were imported into Mimics 21.0 in DICOM format.The C1-T1 vertebrae were reconstructed separately.Subsequently,the established models were imported into the 3-Matic software for disc reconstruction.The perfected models were then imported into Hypermesh software for meshing of the vertebrae,nucleus pulposus,annulus fibrosus,and ligaments,creating valid geometric models.After assigning material properties,the final models were imported into ABAQUS software to observe the joint motion range of the C1-C7 cervical vertebrae segments under different conditions,and to analyze the biomechanical characteristics of the annulus fibrosus,nucleus pulposus,endplates,and small joint cartilage of each cervical spine segment. RESULTS AND CONCLUSION:(1)In six different conditions,the joint motion range of the C1 vertebra in the cervical spine models of both normal adolescent and adolescent patient with cervical disc herniation was higher than that of the other vertebrae.Additionally,the joint motion range of each cervical spine segment in normal adolescent was greater than that in adolescent patient with cervical disc herniation.(2)In the cervical spine model of normal adolescent,the maximum stress values in the annulus fibrosus and nucleus pulposus were found on the left side during C2-3 flexion conditions(0.43 MPa and 0.17 MPa,respectively).In the cervical spine model of adolescent patient with cervical disc herniation,the maximum stress values were found on the left side during C7-T1 flexion conditions(0.54 MPa and 0.18 MPa,respectively).(3)In the cervical spine model of normal adolescent,the maximum stress value on the endplate was found on the left side of the upper endplate of C3 during flexion conditions(1.46 MPa).In the model of adolescent patient with cervical disc herniation,the maximum stress value on the endplate was found on the left side of the lower endplate of C7 during flexion conditions(1.32 MPa).(4)In the cervical spine model of normal adolescent,the maximum stress value in the small joint cartilage was found in the C2-3 left rotation conditions(0.98 MPa).In adolescent patient with cervical disc herniation,the stress in the small joint cartilage significantly increased under different conditions,especially in C1-2,with the maximum stress found during left flexion(3.50 MPa).(5)It is concluded that compared to normal adolescent,adolescent patient with cervical disc herniation exhibits altered cervical curvature and a decrease in overall joint motion range in the cervical spine.In adolescent with cervical disc herniation,there is a significant increase in stress on the annulus fibrosus,nucleus pulposus,and endplates in the C7-T1 segment.The stress on the left articular cartilage of the C1-2 is notable.Abnormal cervical curvature may be the primary factor causing these stress changes.

OBJECTIVE: To assess the efficacy and safety of Erzhu Jiedu Decoction (EZJDD) Granules in treating mid-advanced hepatitis B virus-associated primary liver cancer (HBV-PLC) patients with Pi (Spleen)-deficiency and dampness-heat syndrome. METHODS: From January 2021 to June 2023, a cohort of 132 patients were enrolled and randomly assigned to a control group or a EZJDD group according to the random numbers, with 66 patients in each group. The patients in the control group received conventional treatment for 3 months, followed by a 3-month follow-up. In addition to the conventional treatment, patients in the EZJDD group were administered EZJDD Granules (10.9 g/pack, 2 packs twice per day) orally for same duration. Progression-free survival (PFS) as primary outcome was evaluated by Kaplan Meier method. Karnofsky performance status (KPS) scores were used to assess the quality of life in two groups before and after treatment, and survival rates were determined as well. The efficacy of Chinese medicine syndrome was calculated with Nimodipine method. Liver function, tumor indicators and T lymphocyte subsets were measured, respectively. Safety indicators were recorded and assessed. RESULTS: Of the 116 patients who completed the study, 57 were in the control group and 59 in the EZJDD group. The median PFS was 3.53 months (106 days) in the EZJDD group compared to 2.33 months (70 days) in the control group (P=0.005). Six-month survival rate was 52.63% (30/57) in the control group and 69.49% (41/59) in the EZJDD group (P=0.039). The median KPS score in the EZJDD group [70(63, 90)] was higher than that in the control group [70(60, 80)] (P=0.013). The total effective rate of CM syndrome was 52.63% (30/57) in the control group and 77.97% (46/59) in the EZJDD group (P=0.005). The levels of alpha fetoprotein, alpha fetoprotein-L3, alpha-L-fucosidase and protein induced by Vitamin K absence or antagonist- II in the EZJDD group increased less than the control group (P>0.05). CD8⁺ levels were decreased, while CD3⁺ and CD4⁺ levels, as well as CD4⁺/CD8⁺ ratio were significantly increased in the EZZJD group (P<0.05). No treatment-related adverse reactions were observed during the study. CONCLUSION EZJDD Granules significantly prolonged the median PFS and improved 6-month survival rate in patients with mid-advanced HBV-PLC (Registration No. ChiCTR2200056922).

Objective:To investigate the predictive value of serum neutrophil gelatinase-associated lipocalin(NGAL),calcitonin gene-related peptide(CGRP),and neutrophil-to-lymphocyte ratio(NLR)for the prognostic regression of elderly patients with stroke complicated with pulmonary infection(SCPI).Methods:This study was a retrospective single-center study,149 elderly patients with SCPI who were admitted to Inner Mongolia Baogang Hospital from June 2020 to June 2024 were selected,they were divided into poor prognosis group(n=56)and good prognosis group(n=93)according to the prognosis.Baseline data and laboratory test indicators were collected,and NLR was calculated.Serum NGAL and CGRP levels were measured by ELISA.Influencing factors of poor prognosis of elderly patients with SCPI were analyzed by Multivariate logistic regression.Predicts value was analyzed by Receiver operating characteristic(ROC)curve.Results:Compared with good prognosis group,the poor prognosis group had higher of aged ≥ 70 years,incidence of hemorrhagic stroke,serum creatinine,white blood cell count,national institute of health stroke scale(NIHSS),platelet count,C-reactive protein,NGAL,and NLR levels,longer nerosurgery intensive care unit(NICU)stay,and lower CGRP levels(P＜0.05).Higher CGRP level was an independent protective factor of poor prognosis of elderly patients with SCPI(OR＜1,P＜0.05).Age ≥ 70 years,hemorrhagic stroke,longer NICU stay,higher NIHSS score,higher NGAL level and higher NLR were independent risk factors of poor prognosis of elderly patients with SCPI(OR＞1,P＜0.05).The area under the curve(AUC)for predicting the prognostic regression of elderly patients with SCPI used NGAL,CGRP,and NLR alone or in combination was 0.777,0.771,0.786,and 0.927,respectively,with the combination of three factors showed the highest predictive power(P＜0.05).Conclusion:Age ≥70 years,hemorrhagic stroke,longer NICU stay,higher NIHSS score,higher NGAL level and higher NLR are independent risk factors of poor prognosis of elderly patients with SCPI,while higher CGRP level is an independent protective factor.The combination detection of NGAL,CGRP and NLR can improve the predictive value of prognostic regression in elderly patients with SCPI.

Wumei Pills, a classic traditional Chinese medicine(TCM) formula, are widely used in the treatment of biliary ascariasis and diarrhea. In recent years, studies have shown that Wumei Pills have advantages in the treatment of type 2 diabetes mellitus(T2DM), while there are no relevant reports that systematically evaluate the efficacy of Wumei Pills in the treatment of T2DM. This study addresses this issue by systematically evaluating the efficacy and safety of Wumei Pills, aiming to provide an evidence-based basis for clinical practice. PubMed, Cochrane Library, EMbase, Web of Science, CNKI, Wanfang, and VIP were researched for the randomized controlled trial(RCT) involving Wumei Pills for the treatment of T2DM that were published from inception to September 2024. RevMan 5.3 was used for the Meta-analysis of the data. A total of 18 RCTs were included, with a total of 1 437 patients. Meta-analysis produced the following results.(1)Treatment group outperformed control group in terms of overall response rate(RR=1.28, 95%CI[1.14, 1.43], P<0.000 1), fasting blood glucose(FPG)(WMD=-0.69, 95%CI[-0.93,-0.46], P<0.000 01), two-hour postprandial plasma glucose(2hPG)(WMD=-0.74, 95%CI[-1.17,-0.31], P<0.000 7), glycated hemoglobin(HbA1c)(WMD=-0.39, 95%CI[-0.60,-0.18], P=0.000 3), high-density lipoprotein(HDL)(WMD=0.38, 95%CI[0.28, 0.48], P<0.000 01), and body mass index(BMI)(WMD=-1.41, 95%CI[-2.40,-0.42], P=0.005).(2)The two groups had comparable effects regarding total cholesterol(TC)(WMD=-0.53, 95%CI[-1.13, 0.08], P=0.09) and low-density lipoprotein(LDL)(WMD=-0.25, 95%CI[-0.56, 0.06], P=0.12).(3)Triglycerides(TG)(WMD=-0.28,95%CI [-0.59,0.03],P=0.08), sensitivity analysis showed potential reduction effect(WMD=-0.20,95%CI[-0.36,-0.04],P=0.01). Occurrence of adverse drug reaction(RR=0.43,95%CI [0.23,0.80],P=0.007), sensitivity analysis showed significant disappearance(RR=0.56,95%CI[0.26,1.22],P=0.14), suggesting that the efficacy of treatment group was not better than that of control group. The results indicate that the treatment of T2DM with Wumei Pills is greatly related to the improvement of glucose metabolism, lipid metabolism, and clinical efficacy. The findings provide a basis for clinical application of Wumei Pills in treating T2DM, while the conclusion remains to be verified by clinical studies with higher quality.
