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.

Objective To evaluate the effect of donor gender on short-term survival rate of lung transplant recipients. Methods A retrospective analysis was conducted on the data of 1 066 lung transplant recipients. The log-rank test was used to evaluate the differences in short-term fatality among different donor gender groups and donor-recipient gender combination groups. Multivariate Cox regression, propensity score (PS) regression, and propensity score matching (PSM) were employed to control for confounding factors and further assess the differences in fatality. Subgroup analyses were also performed based on donor gender. Results Multivariate Cox regression analysis showed no statistically significant differences in fatality at 30 days, 1 year, 2 years and 3 years postoperatively between male and female donor groups (all P>0.05). After PS regression and PSM, univariate Cox regression analysis indicated that recipients from female donors had a higher fatality at 2 years postoperatively compared to those from male donors, with hazard ratios (95% confidence intervals) of 1.29 (1.01-1.65) and 1.36 (1.03-1.80) respectively. Multivariate Cox regression analysis also revealed no statistically significant differences in fatality at various follow-up time points among different donor-recipient gender combination groups (all P>0.05). Subgroup analyses based on donor sex showed no statistically significant differences in fatality among recipients of different gender within either male or female donor groups (all P>0.05). Conclusions Female donors may reduce the short-term postoperative survival rate of lung transplant recipients, but this negative impact is not sustainable in the long term. At present, there is no evidence to support the inclusion of sex as a factor in lung allocation rules.

OBJECTIVE To explore clinical characteristics and risk factors of drug-induced hypofibrinogenemia， providing a reference for rational clinical drug use. METHODS Retrospective case analyses literature on drug-induced hypofibrinogenemia were collected from domestic and international databases from their inception to December 31， 2024. The patients’ gender， age， fibrinogen （FIB） levels before and after treatment， drug types， the incidence of drug-induced hypofibrinogenemia， time of occurrence， bleeding rates， clinical manifestations， risk factors， and protective factors were all analyzed. RESULTS A total of 40 retrospective case analysis studies were included， involving 17 313 patients. Patient age ranged from 0.83 to 78.40 years， with males accounting for 16.90%-81.00%. The involved drugs comprised 5 categories and 13 specific agents， including tigecycline， snake venom hemocoagulase， tocilizumab， and alteplase， etc. The incidence of drug-induced hypofibrinogenemia ranged from 0 to 100%， occurring between 2 hours and 9 months after drug administration， and FIB levels rebounded in most patients after drug discontinuation. The bleeding rate varied from 0% to 91.30%， including epistaxis， airway bleeding， gastrointestinal bleeding， and cerebral hemorrhage. Risk factors included high drug dosage， prolonged treatment duration， abdominal infection， advanced age， and low baseline FIB levels. Protective factors were only mentioned in studies on tigecycline， including skin and soft tissue infections and high baseline FIB levels. CONCLUSIONS Drug-induced hypofibrinogenemia is commonly associated with tigecycline， hemocoagulase， and tocilizumab. Its clinical features vary depending on the drug， and risk factors include high drug dosage， prolonged treatment， low baseline FIB levels， and advanced age. For high-risk medications， individualized medication management and monitoring of FIB levels are recommended.

Platycodonis Radix is the dry root of Platycodon grandiflorum of Campanulaceae, which has a variety of pharmacological effects and is a commonly used bulk Chinese medicine. In this study, the chloroplast genome sequences of six P. grandiflorum from different producing areas has been sequenced with Illumina HiSeq X Ten platform. The specific DNA barcodes were screened, and the germplasm resources and genetic diversity were analyzed according to the specific barcodes. The total length of the chloroplast genome of 6 P. grandiflorum samples was 172 260-172 275 bp, and all chloroplast genomes showed a typical circular tetrad structure and encoded 141 genes. The comparative genomics analysis and results of amplification efficiency demonstrated that trnG-UCC and ndhG_ndhF were the potential specific DNA barcodes for identification the germplasm resources of P. grandiflorum. A total of 305 P. grandiflorum samples were collected from 15 production areas in 9 provinces, for which the fragments of trnG-UCC and ndhG_ndhF were amplificated and the sequences were analyzed. The results showed that trnG-UCC and ndhG_ndhF have 5 and 11 mutation sites, respectively, and 5 and 7 haplotypes were identified, respectively. The combined analysis of the two sequences formed 13 haplotypes (named Hap1-Hap13), and Hap4 is the main genotype, followed by Hap1. The unique haplotypes possessed by the three producing areas can be used as DNA molecular tags in this area to distinguish from the germplasm resources of P. grandiflorum from other areas. The haplotype diversity, nucleotide diversity and genetic distance were 0.94, 4.79×10^-3 and 0.000 0-0.020 3, respectively, suggesting that the genetic diversity was abundant and intraspecific kinship was relatively close. This study laid a foundation for the identification of P. grandiflorum, the protection and utilization of germplasm resources, and molecular breeding.

OBJECTIVE: To assess the outcomes after acupoint application in patients with pharyngeal pain in a real-world settings, and analyze the characteristics of effective population and prescription characteristics of acupoint application. METHODS: Based on CHUNBO platform, patients with pharyngeal pain who were candidates for acupoint application on the basis of physician-evaluation, were enrolled in a nationwide, prospective, 69-week multicenter observational study from August 2020 to February 2022. Propensity score matching (PSM) was used to match the confounding factors and the association rules were used to analyze the characteristics of effective population and prescription characteristics of acupoint application. Outcome assessments included the disappearance rate of pharyngeal pain (within 3, 7, and 14 days), disappearance time of pharyngeal pain, as well as adverse events. RESULTS: Of 7,699 enrolled participants, 6,693 (86.9%) received acupoint application and 1,450 (21.7%) with non-acupoint application. After PSM, there were 1,004 patients each in the application group (AG) and non-application group (NAG). The disappearance rate of pharyngeal pain in the AG at 3, 7, and 14 days were all higher than those in the NAG (P<0.05). The disappearance time of pharyngeal pain in the AG were shorter than that in the NAG (logrank P<0.001, hazard ratio=1.51, 95% confidence interval: 1.41-1.63). The median age of effective cases was 4 years, mainly 3-6 years old (40.21%). The disappearance rate of pharyngeal pain in the application group with tonsil diseases was 2.19 times higher than that in the NAG (P<0.05). The commonly used acupoints for the effective cases were Tiantu (RN 22), Shenque (RN 8) and Dazhui (DU 14). The commonly used herbs for the effective cases were Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae. Among them, Natrii sulfas was applied to RN 8 most frequently (support 84.39%). A total of 1,324 (17.2%) patients experienced AEs, and mainly occurred in the AG, with significant difference in the incidence of AEs between goups (P<0.05). All AEs reported were the first grade, and the average regression days of AEs was 2.8 days. CONCLUSIONS Acupoint application in patients with pharyngeal pain resulted in improved effective rate and shortened duration, especially children aged 3-6 years old, and those with tonsil diseases. Acupoint of RN 22, RN 8 and DU 14, Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae were the most commonly used herbs in the treatment of pharyngeal pain.
