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.

Isosteviol is a tetracyclic diterpenoid compound obtained by hydrolysis of natural stevia glycoside under acidic conditions. It has many pharmacological activities, such as anti-tumor, hypoglycemic, anti-inflammatory and antibacterial. Due to its low water solubility, low activity and low bioavailability, isosteviol has poor performance. In order to overcome these shortcomings, scholars have obtained a large number of isosteviol derivatives with novel structures and excellent activity. In this paper, we review the recent progress in the research on the structure modification, biological activity, structure-activity relationship and microbial transformation of isosteviol, in order to provide a reference for the development of new drugs of isosteviol and its derivatives.

Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective To investigate an automated pretreatment technology for detecting levels of free silica in workplace dust. Methods An fully automated pretreatment workstation for detecting free silica levels in workplace dust was developed by integrating graphite-controlled digestion temperature, online-controlled dilution of digestion solutions, and filtration endpoint recognition based on monitoring technology, combined with multi-channel synchronous measurements. Results The fully automatic pretreatment workstation was used to digest and filter 14 standard samples of free silica produced by three institutions, and then detected by pyrophosphate method. The result range of high-, medium-, and low-level free silica standard samples detection was 66.5%-84.8%, 40.0%-44.5%, and 2.1%-24.8%, respectively. The mean relative standard deviations were 3.9%, 1.4% and 1.5%. Conclusion The fully automated pretreatment workstation produced results that met relevant requirements. It can effectively replace the manual digestion and filtration steps of the pyrophosphate method to measure free silica levels in workplace dust and enable rapid detection of free silica in dust samples.

Objective To investigate the effect and mechanism of transplantation of neuregulin1(NRG1)gene-modified bone marrow mesenchymal stem cells(BMSCs)on the repair of hemi-transected spinal cord injury(SCI)in rats.Methods Isolated and cultured rat BMSCs,followed by transfection with the NRG1 gene.The levels of NRG1 in BMSCs lysate and culture supernatant was deected by ELISA method,and the proliferation activity of the BMSCs was detected by cell counting method.Forty-three healthy 8-week-old SD rats were randomly divided into control group(n=10),SCI model group(n=10),BMSCs group(n=10),and NRG1-BMSCs group(n=13).After establishing the spinal cord hemisection model,animals received in-situ transplantation of BMSCs or NRG1-BMSCs.On the 1,7,14,21,and 28 days after transplantation,the hind limb motor function was evaluated using BBB score and inclined plate test;on the 7th day after transplantation,the migration and distribution of transplanted cells was monitored using a fluorescence microscope;on the 28th day after transplantation,the pathological changes of rat spinal cord tissues was examined using HE staining and Nissl staining;cell apoptosis using TUNEL staining,and levels of endoplasmic reticulum stress-related proteins[X-box binding protein 1(XBP1),C/EBP homologous protein(CHOP),activating transcription factor 4(ATF4),ATF6,glucose-regulated protein 78(GRP78)]and apoptosis-related proteins[B-cell lymphoma-2(Bcl-2)and Bcl-2-associated protein X(Bax)]in rat spinal cord tissues using Western blotting.Results BMSCs were successfully isolated,cultured,and transfected with the NRG1 gene.ELISA method results showed that the NRG1 contents in the NRG1-BMSCs lysate and culture supernatant were significantly higher than that of BMSCs in a time-dependent manner(P<0.05).The proliferation activity of NRG1-BMSCs was significantly higher than that of BMSCs(P<0.05).On the 21 and 28 days after transplantation,the BBB score and the slope angle of the inclined plate in NRG1-BMSCs group were higher than those in SCI model group or BMSCs group(P<0.05).However,it did not reverse to the level in control group(P<0.05).On the 28th day after transplantation,compared with the SCI model group and BMSCs group,neuronal pyknosis reduced,the Nissl body density increased,the expression levels of XBP1,CHOP,ATF4,ATF6,GRP78,and Bax,and the rate of TUNEL-positive cells significantly reduced in NRG1-BMSCs group(P<0.05),and the expression level of Bcl-2 significantly increased(P<0.05).Conclusion Transplantation of NRG1 gene-modified BMSCs can alleviate SCI and improve the recovery of motor function in rats.The mechanism may be related to promoting the proliferation activity of BMSCs,inhibiting cell apoptosis,and mitigating endoplasmic reticulum stress.

As an emerging discipline that combines traditional diagnostic methods with modern scientific technology,micro syndrome differentiation has good prospects for development,but there are some controversies in the research process.Based on ancient and modern literature,this article reviewed the origin and flow of research on micro syndrome differentiation,and summarized the problems to be improved in the process of research on micro syndrome differentiation from three aspects:application of disease type,guiding ideology and micro indicators.Based on this,the article further expounded the new thinking on"near-micro"syndrome differentiation from three aspects:connotation,scope of application,and links to traditional identification and micro-identification,and pointed out that the modern medical detection basis should be incorporated into the field of TCM syndrome differentiation,and at the same time,it should be based on the overall thinking mode of TCM,which would provide a new idea for the development of modern TCM diagnosis technology.
