Objective: To investigate the seroepidemiological characteristics of hepatitis B among outpatients in medical institutions in Jiaxing City, Zhejiang Province, so as to provide a reference for formulating region-specific hepatitis B prevention and control strategies. Methods: From April to June 2024, outpatients were selected as study subjects from sentinel medical institutions in Jiaxing City. Information such as gender and age was collected. Venous blood samples were obtained and serological markers including hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B e antigen (HBeAg), hepatitis B e antibody (HBeAb), and hepatitis B core antibody (HBcAb) were tested. Positive rates of hepatitis B virus (HBV) serological markers were analyzed by genders and ages. Results: A total of 1 468 outpatients were included, among whom 721 were males (49.11%) and 747 were females (50.89%). The mean age was (46.41±19.66) years. The positive rates of HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb were 7.29%, 44.75%, 1.84%, 23.50%, and 42.03%, respectively. The HBcAb positive rate in males was significantly higher than in females (46.05% vs. 38.15%, P<0.05), while no statistically significant gender differences were observed in the positive rates of other four HBV serological markers (all P>0.05). Except for HBsAb, the positive rates of the other four HBV serological markers showed statistically significant differences across different age groups (all P<0.05). Pairwise comparisons results showed that the HBsAg positive rates in age groups of 20-<40 years and 40-<60 years were 9.48% and 9.57%, respectively, which were higher than those in age groups of <20 years (1.43%) and ≥60 years (2.75%) (all P<0.05). A total of 17 HBV serological marker patterns were observed, among which the proportion of all markers negative was the highest, at 39.65%. The proportions of "small three positive" (HBsAg+, HBeAb+, HBcAb+) and "large three positive" (HBsAg+, HBeAg+, HBcAb+) patterns were 4.77% and 1.50%, respectively. Among HBsAg-positive individuals, the proportions of the "small three positive" pattern across age groups were 0, 45.45%, 90.00%, and 81.82%, while those of the "large three positive" were 0, 36.36%, 5.00%, and 0, with statistically significant differences across age groups (both P<0.05). Conclusions The positive rate of HBsAg among outpatients in medical institutions in Jiaxing City is relatively high, with a notable proportion of individuals showing either no immunity or non-response to vaccination. It is recommended to strengthen hepatitis B immunization efforts among the population aged 20-<60 years, and to enhance monitoring and interventional treatment for "small three positive" and "large three positive" patterns.

Objective:To investigate the efficacy and safety of glofitamab in the treatment of relapsed/refractory diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 11 patients with relapsed/refractory DLBCL who were treated with glofitamab in Sichuan Provincial People's Hospital from March 2024 to October 2024 were retrospectively analyzed. All patients received glofitamab monotherapy. Dose escalation was required in the first course, and glofitamab at a dose of 30 mg was administered from the second to the 12th course. The general data, clinical manifestations, laboratory examination results, Eastern Cooperative Oncology Group (ECOG) performance score, previous treatment history, therapeutic effect after medication and adverse reactions were collected.Results:Among 11 patients, there were 8 males and 3 females, with the median age [ M ( Q1, Q3)] of 60 (51, 76) years; 1 case was primary central nervous system DLBCL. The median number of prior treatment lines was 3 (2, 3) lines, and 6 cases received ≥3 lines of therapy; 1 case was double DLBCL and 3 cases was complicated with p53 mutations. The median follow-up time was 5 months (2-7 months). After treatment of the median number of glofitamab, 3 cases achieved complete remission, among which 1 case successfully bridged to autologous hematopoietic stem cell transplantation; 1 case had the stable disease and 7 cases achieved partial remission. Grade 1-2 adverse events included mild leukopenia in 3 patients, mild anemia in 4 patients, thrombocytopenia in 1 patient, and lymphopenia in 8 patients. Grade 3 hematologic adverse events included thrombocytopenia in 1 patient and severe lymphopenia in 1 patient. Non-hematological toxicities included mild rash in 1 patient, grade 1 liver dysfunction in 3 patients and inflammatory factor storm in 4 patients. No medication stop or deferral was found in patients due to severe adverse events. Conclusions:Glofitamab demonstrates a high response rate in the treatment of relapsed/refractory DLBCL, with manageable adverse events and a favorable safety.

Objective:To explore the correlation between serum γ-glutamyl transpeptidase (γ-GGT), albumin/globulin ratio (AGR), miR-208a levels and cardiac function classification and prognosis in patients with chronic heart failure (CHF).Methods:A total of 150 CHF patients who were diagnosed in the Affiliated Hospital of Yan′an University from May 2020 to May 2023 and followed up for at least 1 year were retrospectively selected as the CHF group. Eighty healthy volunteers recruited from the physical examination center were selected as the control group. The serum levels of γ-GGT, AGR and miR-208a were compared between the two groups. Subgroup analysis was conducted according to the New York Heart Association (NYHA) classification of CHF patients and whether major adverse cardiovascular events (MACE) occurred during 1-year follow-up. Multivariate logistic regression analysis was used to screen the influencing factors of prognosis in CHF patients. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of each index for adverse prognosis of patients.Results:The serum levels of γ-GGT and miR-208a in the CHF group were significantly higher than those in the control group (all P<0.05), while the AGR level was lower than that in the control group ( P<0.05). The serum levels of γ-GGT and miR-208a in patients with NYHA class Ⅳ were significantly higher than those in patients with class Ⅱ and Ⅲ (all P<0.05), and the AGR level was lower than that in patients with class Ⅱ and Ⅲ (all P<0.05); the serum levels of γ-GGT and miR-208a in patients with NYHA class Ⅲ were significantly higher than those in patients with class Ⅱ (all P<0.05). The serum levels of γ-GGT and miR-208a in the MACE group were significantly higher than those in the non-MACE group (all P<0.05), while the AGR level was lower than that in the non-MACE group ( P<0.05). Prolonged CHF course, NYHA classification ≥class Ⅲ, decreased left ventricular ejection fraction (LVEF), complicated with atrial fibrillation, increased γ-GGT, decreased AGR and increased miR-208a were independent risk factors for adverse prognosis of CHF patients (all P<0.05). ROC curve analysis showed that the areas under the curve (AUC) of γ-GGT, AGR, miR-208a alone and in combination for predicting adverse prognosis of CHF patients were 0.631(95% CI: 0.531-0.731), 0.704(95% CI: 0.602-0.805), 0.753(95% CI: 0.657-0.849) and 0.879(95% CI: 0.818-0.941), respectively. Conclusions:Serum γ-GGT, AGR and miR-208a are closely related to NYHA classification and adverse prognosis of CHF patients. The combined application of the three indicators has important reference significance for predicting the adverse prognosis of patients.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

The impact of hypertensive disorders of pregnancy(HDP)on maternal and fetal outcomes is well-established.However,the relationship between high-normal blood pressure(BP)and HDP,as well as its association with adverse maternal-fetal outcomes,remains unclear.This retrospective study analyzed singleton pregnancies delivered at Obstetrics and Gynecology Hospital,Fudan University from Jan 2021 to Dec 2021.Participants were categorized into a normal BP group(BP<130/80 mmHg before delivery admission)and two high-normal BP groups(BP:130-139/80-89 mmHg)with subgroup analysis based on gestational week of BP elevation before and after 20 weeks.Maternal characteristics,HDP incidence and adverse outcomes were compared across groups.The results demonstrated that compared with the normal BP group,both high-normal BP groups showed significantly increased HDP incidence,with more pronounced risk in the high-normal BP(after 20 weeks)group.The high-normal BP(before 20 weeks)group was associated with elevated risks of iatrogenic preterm birth and small for gestational age(SGA).This study provides a theoretical basis for implementing stricter BP monitoring strategies to reduce adverse maternal and neonatal outcomes.

Endometriosis is a common estrogen-dependent disease in women of childbearing age,often leading to chronic pelvic pain,infertility,ovarian cancer,and other serious complications,and jeopardizing the health of women.The pathogenesis of endometriosis is complex and involves the alteration of multiple signaling pathways mediated by hormones,immunity,genetics,and the environment,and their interactions.Wnt/β-catenin signaling is involved in the regulation of embryonic development and tissue homeostasis,and it has recently been implicated in the pathogenesis of endometriosis via multiple pathways.This review considers the biological characteristics of the Wnt/β-catenin signaling pathway and summarizes the main mechanisms and signaling pathways involved in the pathogenesis of endometriosis,as well as the curr-ent research status of the regulation of this signaling pathway by traditional Chinese medicine for the treatment of endometriosis.We aim to clarify how the Wnt/β-catenin signaling pathway affects the development of endometriosis,and suggest that future studies should focus on exploring its potential role as an indicator for the clinical prediction and early diagnosis of endometriosis,thus providing theoretical support for the early diagnosis of this condition and the development of targeted drugs.

The activation of Keap1-Nrf2 signaling pathway is an important mechanism for cells to resist oxidative stress.Under oxidative stress,Keap1 is affected by post-translational modification(PTM)such as glutathione,alky-lation and S-sulfhydrylation,which weakens its binding to Nrf2,leading to Nrf2 accumulation,nuclear translocation and the expression and transcription of downstream detoxification and antioxidant defense proteins.The PTM of Keap1 is involved in the regulation of a variety of oxidative stress-related diseases such as cancer,Parkin-son's disease and atherosclerosis.For example,alkylation inhibits abdominal aortic aneurysm formation,methylation promotes innate resistance of breast cancer,and S-sulfhydrylation improves atherosclerosis,which pro-vides a theoretical basis for finding new drug targets and biomarkers.

Widespread utilization of glyphosate has led to environmental residues,posing potential threats to ecological systems and human health.Traditional methods for detection of glyphosate are limited by specialized equipment and operational techniques,resulting in inefficient responses.Therefore,it is urgent to develop a convenient,sensitive and accurate detection method for detection of glyphosate.Herein,a new naphthalenesulfonamide-based"Turn-on"fluorescent probe was synthesized using 2-chloroaniline and dansyl chloride as raw materials through a one-step process,which showed a good linear relationship between the glyphosate concentration in concentration range of 0.003-70 μmol/L and the fluorescence intensity(R2=0.995),with a detection limit of 2.73 nmol/L(S/N=3).Analytical techniques such as nuclear magnetic resonance(NMR)spectroscopy and high-resolution mass spectrometry(HRMS)were used to investigate the interaction mechanism between the fluorescent probe and glyphosate.The results indicated that a nucleophilic substitution reaction occurred between the probe and the secondary amine(—NH—)of glyphosate,inducing a photoinduced electron transfer(PET)effect which enhanced the fluorescence intensity by 11.2 times.The probe showed good anti-interference ability towards coexisting metal ions,anions and pesticides in water.When applied to determination of glyphosate in the samples such as tap water,river water(Xiangxi River Reservoir),soil,soybeans,and corn,the spiking recoveries ranged from 94.7％to 109.9％,demonstrating the high accuracy and broad applicability of this detection method.A portable test strip based on this fluorescent probe was developed for rapid semi-quantitative analysis of glyphosate.The developed method was rapid,sensitive,and portable,providing theoretical and technical support for on-site measurement of environmental contaminants.
