As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

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 explore EEG characteristics and the therapeutic effect in children with electrical status epilepticus during slow sleep(ESES).Methods The eligible ESES cases in our center from 2014 to 2020 were included.The age at diagnosis of ESES,the duration of ESES,spike wave index(SWI)during wakefulness and the distribution of spike wave during the period of ESES,age at seizure onset,the clinical syndromes and the outcomes after treatment were analyzed.The ESES cases were divided into 4 groups according to the distribution of spike wave:focal ESES,unilateral ESES,bilateral asymmetric ESES,multiple foci ESES.The SWI during the awake stage were divided into 3 groups based on the different rates:≤20%,21%～49%,≥50%.The therapeutic outcomes were classified into three groups:satisfactory response,seizure control and ineffective.Results 50 cases were included,with 32 males and 18 females.The average onset age of ESES was 6 years and 7 months,and the average duration of ESES was 28 months.A significant correlation between the distribution of ESES and the thera-peutic effects was found,bilateral asymmetric ESES had a good therapeutic effects,while multiple foci ESES showed a poor therapeutic effects.The duration of ESES was significantly correlated with therapeutic effects,and the efficacy was worse when the duration was longer than 1 year.A significant relationship between the SWI during wakefulness of ESES and the therapeutic effects was detected,the patient with SWI≤20%during wakefulness had a good therapeutic effect.There was a negative correlation between the onset age of ESES and the duration of ESES and SWI index during wakefulness.There was a positive correlation between the duration of ESES and SWI index during wakefulness.Conclusion Our results suggest that onset age,distribution,duration and SWI during wake-fulness of ESES were correlated with therapeutic outcomes,The patient with SWI≤20%during wakefulness had a good therapeutic effect and have unfavorable outcomes with ESES last more than 1 year.The earlier onset of ESES,the longer duration of ESES and higher SWI during wakefulness will be showed..

Objective:To explore the value of mitoxantrone hydrochloride injection for tracing in endoscopic thyroidectomy (ETE) via anterior chest approach for papillary thyroid carcinoma (PTC) .Methods:A retrospective analysis was conducted on patients undergoing ETE via anterior chest approach for PTC admitted to Beijing Longfu Hospital (Medical Treatment Combination with Peking Union Medical College Hospital) from Sep. 2022 to Mar. 2024. The patients were divided into two groups: the control group (without tracer) and the tracer group (with mitoxantrone hydrochloride injection for tracing). All surgeries were performed by the same thyroid surgical team. Baseline, postoperative pathologies and complications were compared between the 2 groups.Results:A total of 25 patients (13 in the control group and 12 in the tracer group) were included in this study, and the average dissection of unilateral central region lymph nodes in the tracer group was 7.4±4.6, significantly more than in the control group (2.4±1.9) ( P=0.004). There were no instances of mistakenly resected parathyroid gland in the postoperative pathology or accidental injury of recurrent laryngeal nerve in either group. The incidence of transient hypocalcemia did not significantly different between the two groups ( P=0.503). However, the incidence of transient hypoparathyroidism in the tracer group was 1 (1/12,8.3%), significantly lower than in the control group 4 (4/13,30.8%) ( P=0.009). The tracer group exhibited more impressive levels in parathyroid hormone (5.4±8.1) pg/mL compared to the control group (20.0±11.1) pg/mL ( P=0.001) .The total volume of postoperative drainage in the tracer group (142.9±71.7) mL was more than that of the control group (87.7±38.8) mL ( P=0.030). But It did not affect the extubation time in either group ( P=0.610). No residual tracer was observed at the skin puncture site in the tracer group after 2 weeks. Conclusions:Mitoxantrone hydrochloride injection for tracing as tracer in ETE via breast approach can increase the number of pathological lymph nodes dissection in cervical central region. Combined with negative development, identifying and protecting the function of parathyroid glands show feasible and potential application value to improve the safety of thyroidectomy. The use of mitoxantrone hydrochloride injection for tracer has the risk of increased exudation from the surgical area, but does not affect the time to remove the drain.

Objective:To explore the use of near-infrared autofluorescence probe (NIRAF-P) and its application in identifying parathyroid glands during surgery.Methods:A total of 68 patients undergoing thyroid surgery at Peking Union Medical College Hospital and Beijing Longfu Hospital between Dec. 2023 and Jun. 2024 were selected. During the operation, the near-infrared parathyroid gland detector was used to identify the parathyroid gland tissue to be tested, and histopathological examination was performed. The positive predictive value and accuracy of the near-infrared parathyroid gland detector were analyzed.Results:A total of 111 parathyroid glands were identified in 68 patients, and the positive predictive value and accuracy of the NIRAF-P were 95.5% and 94.6%, respectively.Conclusions:The NIRAF-P has high accuracy in identifying parathyroid glands. The standardized application of the NIRAF-P can help improve the efficiency of identifying parathyroid glands during surgery.

Objective To investigate the relationship between serum levels of E-cadherin and β-catenin and calcium phosphorus metabolism and carotid artery calcification in patients with diabetic nephropathy.Methods A total of 112 patients with diabetic nephropathy admitted to the hospital from May 2019 to No-vember 2022 were selected as the study group,and were divided into a carotid artery calcification group(n=44)and a non-carotid artery calcification group(n=68)according to the results of bilateral carotid artery col-or Doppler ultrasound.In addition,90 healthy people who underwent physical examination in the hospital dur-ing the same period were selected as the control group.Serum E-cadherin,β-catenin,calcium phosphorus me-tabolism levels were detected and compared.Pearson correlation analysis was used to explore the relationship between serum E-cadherin,β-catenin and calcium phosphorus metabolism in patients with diabetic nephropa-thy.Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of serum E-cad-herin and β-catenin for carotid artery calcification in patients with diabetic nephropathy.Multivariate Logistic regression analysis was used to explore the influencing factors of carotid artery calcification in patients with di-abetic nephropathy.Results The levels of glycosylated hemoglobin,serum phosphorus,calcium-phosphorus product,parathyroid hormone(iPTH),creatinine,alkaline phosphatase and β-catenin in the study group were higher than those in the control group,and the level of E-cadherin was lower than that in the control group(P＜0.05).The levels of serum phosphorus,serum calcium,calcium phosphorus product,iPTH,creatinine,al-kaline phosphatase and β-catenin in the carotid artery calcification group were higher than those in the non-ca-rotid artery calcification group,and the level of E-cadherin was lower than that in the non-carotid artery calci-fication group(P＜0.05).Pearson correlation analysis showed that serum E-cadherin level in patients with di-abetic nephropathy was negatively correlated with serum phosphorus,serum calcium,calcium phosphorus product,iPTH,creatinine and alkaline phosphatase(r=-0.453,-0.654,-0.365,-0.490,-0.411,-0.377,all P＜0.001).The level of serum β-catenin was positively correlated with serum phosphorus,serum calcium,calcium phosphorus product,iPTH,creatinine,and alkaline phosphatase(r=0.444,0.345,0.421,0.398,0.651,0.622,all P＜0.001).ROC curve analysis showed that the area under the curve of serum E-cad-herin,β-catenin and their combination for predicting carotid artery calcification in diabetic nephropathy were 0.844(95％CI 0.795-0.894),0.853(95％CI 0.801-0.901)and 0.901(95％CI 0.801-0.901),respec-tively.Multivariate Logistic regression analysis showed that serum E-cadherin(OR=3.789,95％CI 2.055-6.983),β-catenin(OR=4.104,95％CI 1.795-9.385),calcium phosphorus product(OR=2.998,95％CI 1.895-4.743)and iPTH(OR=2.713,95％CI 1.787-4.118)were the influencing factors of carotid artery calcification in patients with diabetic nephropathy(P＜0.05).Conclusion The level of β-catenin is increased and the level of E-cadherin is decreased in patients with diabetic nephropathy.β-catenin and E-cadherin are closely related to calcium phosphorus metabolism and carotid artery calcification,which could be used as effec-tive indicators to evaluate carotid artery calcification in patients with diabetic nephropathy.The combination ofβ-catenin and E-cadherin has a higher predictive value for carotid artery calcification.

Objective To investigate the relationship between serum levels of growth differentiation factor-11(GDF-11)and S100 calcium binding protein A4(S100A4)and the severity and disease outcome in diabetic nephropathy(DN)patients.Methods A total of 95 DN patients admitted to the hospital from May 2021 to January 2023 were selected as the study group,and 110 healthy people were selected as the healthy group.The DN patients were divided into mild group(n=66)and severe group(n=29)according to the severity of the disease.The patients were followed up for half a year after discharge,and were divided into good prognosis group(n=64)and poor prognosis group(n=31)according to the prognosis.Serum GDF-11 and S100A4 lev-els were detected by enzyme-linked immunosorbent assay.Spearman rank correlation analysis was used to ex-plore the relationship between serum GDF-11,S100A4 levels and the severity of the disease.Receiver operat-ing characteristic(ROC)curve was used to evaluate the predictive value of serum GDF-11 and S100A4 for dis-ease outcome in DN patients,and multivariate Logistic regression was used to analyze the influencing factors of disease outcome in DN patients.Results The levels of serum GDF-11 and S100A4 in mild group and severe group were higher than those in healthy group,and those in severe group were higher than those in mild group(P＜0.05).Serum GDF-11 and S100A4 levels were positively correlated with the severity of DN patients(P＜0.05).The good prognosis group had significantly lower serum levels of GDF-11 and S100A4 than the poor prognosis group(P＜0.05).The area under the curve(AUC)of serum GDF-11 and S100A4 in predicting the outcome of DN patients was 0.785 and 0.839,respectively,and the AUC of combined prediction was 0.902.The proportion of type 2 diabetes(T2DM)duration,glomerular grade Ⅲ-Ⅳ,interstitial inflammation score 2,interstitial fibrosis and tubular atrophy(IFTA)score 2-3 points,estimate glomerular filtration rate＜60 mL/(min·1.73 m2)and the levels of total cholesterol,triglyceride,low-density lipoprotein choles-terol,24 h urinary protein,glycosylated hemoglobin,C-peptide,hematocrit,and erythrocyte sedimentation rate in the good prognosis group were higher than those in the good prognosis group(P＜0.05).Multivariate Lo-gistic regression analysis showed that the duration of T2DM ≥12.0 years,IFTA score ≥2 points,GDF-11≥700.82 ng/mL,S100A4 ≥ 211.53 ng/L were risk factors for poor prognosis in DN patients(P＜0.05).Conclusion The levels of serum S100A4 and GDF-11 are highly expressed in patients with diabetes mellitus,and are related to the severity and outcome of the disease,which are expected to be potential markers for eval-uating the condition and prognosis of diabetes mellitus.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.
