[Objective] To explore the predictive value of HALP score for prognosis in patients with multiple myeloma (MM). [Methods] A retrospective analysis was conducted on laboratory indicators and related clinical data of newly diagnosed multiple myeloma (NDMM) patients, treated at the Affiliated Hospital of North Sichuan Medical College from January 2016 to October 2023, prior to their first treatment. The HALP score was calculated, and the optimal cutoff value for HALP was determined using X-tile software. Survival analysis was performed using Kaplan-Meier curves for high HALP and low HALP groups. Univariate and multivariate analyses were conducted using the Cox regression model, and a forest plot was generated using Graphpad Prism to illustrate factors that may impact patient prognosis. The predictive ability of HALP score combined with β2-microglobulin and ECOG score for prognosis in MM patients was evaluated using receiver operating characteristic curve (ROC) analysis. [Results] A total of 203 MM patients were included, with the optimal cutoff value for HALP score being 29.15 (P<0.05). Among them, 101 patients were in the low HALP score group, and 102 patients were in the high HALP score group. The results of univariate and multivariate analysis using the Cox regression model showed that a HALP score <29.15 was an independent risk factor for progression-free survival (PFS) and overall survival (OS) (P<0.05). ROC curve analysis indicated that the combination of HALP score with β2-microglobulin and ECOG score had a higher predictive value for prognosis in MM patients compared to using HALP score alone. [Conclusion] The HALP score is closely related to the prognosis of patients with NDMM. A low HALP score indicates a poorer prognosis, while the combination of HALP score with β2-microglobulin and ECOG score provides a higher predictive value when assessed together.

Objective:To explore the relationship between drug literacy and quality of life in patients with multiple chronic diseases.Methods:It was a cross-sectional study. Between March and October 2023, 260 patients with multiple chronic diseases from the General Medicine Department of Peking University Third Hospital were selected using a convenience sampling method. A medication literacy scale, a medication adherence scale, and a health survey scale (SF-36 scale) were used to conduct a questionnaire survey in the patients. The SF-36 scale reflected the quality of life of the patients (including physical health and mental health). A total of 260 questionnaires were distributed, 260 questionnaires were returned, and 240 were effective (92.3%). Single-factor analysis of medication literacy in those patients was conducted using F-test and t-test. The correlation between medication literacy and medication adherence, as well as between medication literacy and quality of life, was analyzed using Pearson′s test. The correlation between different factors and medication adherence, as well as quality of life, in those patients was analyzed using multiple linear regression. Results:Among the 240 patients with multiple chronic diseases, 134 were male and 106 were female, aged (65.84±11.56) years. The drug literacy scale score was (8.36±3.57) points, the SF-36 physical health score was (242.00±87.85) points, mental health score was (275.67±80.29) points, medication compliance scale score was (6.22±1.93) points. The drug literacy was positively correlated with medication compliance ( r=0.157) and mental health ( r=0.165) in patients with multiple chronic diseases (all P<0.05). The score of drug literacy ( SE=2.440), mental health score ( SE=2.523), perceptual impairment ( SE=2.046) and duration of disease ( SE=2.459) were positively correlated with the medication compliance of the patients, while the number of chronic diseases ( SE=-2.818) was negatively correlated with the medication compliance of the patients (all P<0.05). The score of drug literacy ( SE=0.121) and insensible perception disorder ( SE=0.399) were positively correlated with the quality of life of the patients, and the number of chronic diseases ( SE=-0.171) was negatively correlated with the quality of life of the patients (all P<0.05). Conclusion:The drug literacy of patients with multiple chronic diseases is at the medium level, and the drug literacy is positively correlated with medication compliance and quality of life.

Objective:To explore the prognostic value of assessing plasma thrombin-antithrombin complex (TAT) and D-dimer (D-D) in patients with acute ischemic stroke (AIS).Methods:This prospective cohort study enrolled 538 AIS patients admitted to the General Hospital of Tianjin Medical University from July 2021 to May 2024, including 306 males and 232 females, with an average age of (69.5±11.5) years. Among them, there were 147 cases of lacunar infarction, 166 cases of large artery atherosclerosis type, 122 cases of cardioembolic type, and 103 cases of cancer-related type. Follow-up observations were conducted on enrolled patients, data within 30 days after the initiation of acute phase treatment for one week were collected, thrombus-related cerebral ischemic events recurrence served as the endpoint event, starting from August 5, 2021, to June 19, 2024. During the follow-up period, 68 patients experienced endpoint events, including 14 cases of large artery atherosclerosis type, 23 cases of cardioembolic type, and 31 cases of cancer-related type. The plasma levels of TAT and D-D were determined by chemiluminescence method and enzyme-linked immunofluorescence assay respectively. The receiver operating characteristic (ROC) curve was used to analyze the prediction performance of TAT and D-dimer for recurrent ischemic events in AIS patients during the 30-day follow-up period, and the Kaplan-Meier curve was used for survival analysis.Results:Statistically differences were observed in the plasma TAT and D-D levels among patients with different types of AIS ( P<0.05), with cancer-related type had higher levels than cardioembolic type ( P<0.05), and cardioembolic type had higher levels than large artery atherosclerosis type ( P<0.05). In the non-recurrent ischemic event group, the plasma TAT and D-D levels of patients with large artery atherosclerosis type, cardioembolic type and cancer-related type were lower in post-treatment than pre-treatment ( P<0.05). In the recurrent ischemic event group, the plasma D-D levels were higher in post-treatment than pre-treatment in the patients with large artery atherosclerosis type ( P<0.05); there was no statistically difference between the post-treatment and pre-treatment in plasma TAT and D-D levels in patients with cardioembolic type ( P>0.05); in patients with cancer-related type, the TAT and D-D levels were lower in post-treatment than pre-treatment ( P<0.05), but higher than those in the non-recurrence group ( P<0.05). The ROC curve showed that the area under the curve for predicting the risk of ischemic event recurrence within 30 days in AIS patients by plasma TAT combined with D-D on day 7 after treatment was all >0.9 (0.950 for large artery atherosclerosis type, 0.965 for cardioembolic type, and 0.907 for cancer-related types). Survival analysis indicated that various patients with both indicators above the critical value had an increased cumulative risk probability of adverse events (log-rank χ 2=93.667, 109.266, and 58.433, respectively, with all P<0.001). Conclusion:The changes of plasma TAT and D-D levels in AIS patients are associated with stroke type and coagulation activation, and dynamic monitoring of these two indicators could help evaluate the treatment effect and predict the risk of recurrent ischemic events.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

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.

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering. We discuss strategies to increase ADC efficacy and safety, including multitarget approaches, pH-dependent antibodies, and masked peptide technologies. The importance of comprehensive antigen expression profiling in both tumor and normal tissues is emphasized, highlighting the role of advanced technologies, such as single-cell sequencing and artificial intelligence, in optimizing target selection. Furthermore, we explore combination therapies and innovations in linker‒payload chemistry, which may provide approaches for expanding the therapeutic window of ADCs. These advances pave the way for the development of more precise and effective cancer treatments, potentially extending ADC applications beyond oncology.

Objective:To investigate whether biochanin A(BCA)has a protective effect against dextran sodium sulfate(DSS)-in-duced ulcerative colitis(UC)in mice.Methods:Thirty C57BL/6N mice were randomly divided into normal control group,DSS model group,sulfasalazine(SASP)-positive drug control group,and low/medium/high-dose(5 mg/kg,10 mg/kg,and 20 mg/kg)BCA groups.The mouse model of UC was induced by administering 2.5%DSS aqueous solution for 7 days.During the experimental period,both the normal control and model groups were given 0.5%carboxymethyl cellulose sodium solution daily by gavage.The positive control group was given 100 mg/kg SASP,while the BCA groups were given BCA suspensions at doses of 5 mg/kg,10 mg/kg,and 20 mg/kg.The ad-ministration lasted for 10 days.Body weight changes and fecal status of the mice were recorded every day;the colon was dissected,col-lected,and measured for its length.The colon was stained with Hematoxylin-Eosin for pathomorphological study.Quantitative poly-merase chain reaction was used to determine the levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and interleukin-10(IL-10)in the colon.Immunofluorescence was used to determine the expression of tight junction proteins,zonula occluden-1(ZO-1)and occludin,in the colon.Results:It showed that 5 mg/kg and 10 mg/kg BCA significantly alleviated weight loss in mice with UC,while 5 mg/kg,10 mg/kg,and 20 mg/kg BCA reduced the disease activity index scores.Additionally,BCA showed similar effects to SASP in improving the structure and reducing the shortening of the colon in mice with UC.Compared with the model group,all BCA groups had significantly decreased TNF-α(P=0.024、P=0.060、P=0.003)and IL-6(P=0.002、P<0.001、P<0.001)and significantly increased IL-10(P=0.006、P=0.003、P<0.001),with varying degrees of up-regulated expression of tight junction proteins.Conclusion:BCA can effectively alleviate DSS-induced symptoms,reduce intes-tinal damage,and protect the intestinal barrier in mice with UC.

Objective To explore the value of the ratio of soluble FmS-like tyrosine kinase-1(sFlt-1)to placental growth factor(PlGF)in predicting vitamin D deficiency in pregnant women with preeclampsia.Methods A total of 740 singleton pregnant women who underwent prenatal examination in Qijiang Health Center for Maternal and Child Care from January to November 2023 and were able to complete follow-up were selected as the research subjects.They were divided into the normal group(n=44)and the deficiency group(n=696)according to the vitamin D[1,25-(OH)2D3]level.Information such as age,BMI,pregnancy histo-ry,family history and medical history of each group was collected.5 mL of peripheral venous blood was drawn after fasting for 6-8 hours at 12-14 weeks of pregnancy to detect the levels of sFlt-1,PlGF and vitamin D in peripheral blood,and evaluated the predictive value of sFlt-1/PlGF for vitamin D deficiency in preeclampsia.Results There were no statistically significant differences in general conditions such as height,age,BMI,edu-cational level and occupation between the two groups(P>0.05).There were statistically significant differ-ences in the prenatal weight,vitamin D level,sFlt-1/PlGF and neonatal birth weight between the two groups(P<0.05).The results of univariate analysis showed that the prenatal weight,sFlt-1/PlGF,and neonatal birth weight were risk factors for vitamin D deficiency in patients with PE.The results of multivariate analysis showed that sFlt-1/PlGF and neonatal birth weight were factors for predicting vitamin D deficiency in patients with PE(P<0.05).All these variables are used to establish the nomogram prediction model.The receiver op-erating characteristic(ROC)curve showed that area under the curve(AUC)of the training group and the val-idation group was 0.66(95%CI:0.56-0.77)and 0.63(95%CI:0.49-0.76),respectively.Conclusion In pregnant women with preeclampsia,elevated sFlt-1/PlGF may be an early warning indicator for predicting vi-tamin D deficiency.
