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.

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.

Objective To explore the therapeutic mechanism of maggot for psoriasis-like lesions in mice from the perspective of immune stress and complement activation regulation.Methods Thirty-six male C57BL/6 mice were randomly divided into control group,model group,maggot(1.25%,2.5%,and 5%)groups,and Benvitimod(1%)group.Psoriasis-like lesions were induced by application of imiquimod cream,and the severity of skin lesions was assessed using the modified Psoriasis Area and Severity Index(MPASI)score.Auricular swelling of the mice was observed,and histopathological changes of the skin lesions were examined with HE staining.Scratching behavior of the mice was observed and the spleen index was calculated.Toluidine blue staining was used to detect mast cells in the skin lesions,and serum levels of IgG,IgM,the complements CH50,C1s,C3,C3a,C5 and C5a,and the inflammatory factors IL-23,IL-17A and TNF-α were determined with ELISA.Results In mice with imiquimod-induced psoriasis-like skin lesions,treatment with the maggot at the 3 doses significantly decreased MPASI score,alleviated auricular swelling and pathologies in the skin lesions,reduced scratching behaviors,spleen index,and the number of mast cells in the lesions.Treatment with high-dose maggot significantly lowered serum levels of IgG,C1s,C3a,C5a,IL-23,IL-17A and TNF-α and the levels of C1s,C3,C3a,C5 and C5a in the lesion tissue,and increased serum levels of CH50,C3,and C5.The therapeutic effect of maggot showed a dose-effect dependence.Conclusion Maggot can alleviate psoriasis-like skin lesions in mice by inhibiting immune stress and complement activation.

Objective:To explore the influencing factors and effectiveness of community follow-up in patients with cardiac implantable electronic device (CIED) implantation.Method:A total of 132 patients who received CIED implantation in the Department of Cardiology of Tongren Hospital, Shanghai Jiao Tong University School of Medicine from February 2021 to February 2022 were enrolled in this prospective cohort study. Among them 33 patients were followed up in community health service centers associated with Tongren Hospital (community follow-up group) and 99 matched patients were followed up in the CIED outpatient clinic of the hospital (outpatient follow-up group) with a ratio of 1∶3. The clinical data of the selected patients were collected through a questionnaire survey; the follow-up data were extracted through the CarelinkExpress electronic follow-up platform and the CIED outpatient information system of Tongren Hospital. Adjustment of the treatment protocol or CIED parameters at follow-up, and the referral from the community health service centers were defined as visit with-an-action (VWA). The endpoint of follow-up was the occurrence of major adverse events. The multivariate logistic regression model was used to analyze the factors influencing patient selection for community follow-up.Results:The univariate analysis showed that the frequency of visits to community health service centers and the service contracting rate in community follow-up group were higher than those of outpatient follow-up group ( P<0.05). The multivariate logistic regression analysis showed that the contracted community physician service was an independent influencing factor of patient choosing community follow-up ( OR=2.143, 95% CI: 1.103-4.166, P=0.025). A total of 469 visits of followed up occurred in 132 patients, including 45 community visits and 424 outpatient visits. VWA accounted for 22.2% (10/45) in the community follow-up group, and 17.2% (73/424) in the outpatient follow-up group ( P>0.05). There was no significant difference in the safety and effectiveness indicators (VWA, major adverse events, and unplanned follow-up) between the two groups ( P>0.05). More patients in the community follow-up group walked to the hospital than the outpatient follow-up group ( P<0.05);and the main transportation for the later was by bus or taxi(42(42.4%)or 41(41.4%)). The average waiting time in the community follow-up group was significantly shorter than that in outpatient follow-up group ( P<0.05). The total time required for a single follow-up in the community follow-up group was 50.0 (45.0, 59.5) minutes, which was significantly shorter than that in the routine outpatient follow-up group (107.0 (90.0, 135.0) minutes, P<0.05). Conclusions:The contracting with community physicians is an independent influencing factor for CIED implanted patients to choose community follow-up. The safety and effectiveness of community follow-up are comparable to routine outpatient follow-up, and community follow-up is more convenient.

Background::Urticaria is a common skin disease characterized by episodes of wheals, and it has a negative effect on patients’ quality of life. Large-scale population-based epidemiological studies of urticaria are scarce in China. The aim of this survey was to determine the prevalence, clinical forms, and risk factors of urticaria in the Chinese population.Methods::This survey was conducted in 35 cities from 31 provinces, autonomous regions, and municipalities of China. Two to three communities in each city were selected in this investigation. Participants completed questionnaires and received dermatological examinations. We analyzed the prevalence, clinical forms, and risk factors of urticaria.Results::In total, 44,875 questionnaires were distributed and 41,041 valid questionnaires were collected (17,563 male and 23,478 female participants). The lifetime prevalence of urticaria was 7.30%, with 8.26% in female and 6.34% in male individuals ( P < 0.05). The point prevalence of urticaria was 0.75%, with 0.79% in female and 0.71% in male individuals ( P < 0.05). Concomitant angioedema was found in 6.16% of patients. Adults had a higher prevalence of urticaria than adolescents and children. Living in urban areas, exposure to pollutants, an anxious or depressed psychological status, a personal and family history of allergy, thyroid diseases, and Helicobacter pylori infection were associated with a higher prevalence of urticaria. Smoking was correlated with a reduced risk of urticaria. Conclusion::This study demonstrated that the lifetime prevalence of urticaria was 7.30% and the point prevalence was 0.75% in the Chinese population; women had a higher prevalence of urticaria than men. Various factors were correlated with urticaria.
