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.

ObjectiveTo explore the application value of probe-based confocal laser endomicroscopy (pCLE) in rapidly detecting and evaluating the morphological characteristics of digestive tract tissues in mice. MethodsTwelve male SPF Kunming mice aged 6 weeks were randomly divided into two groups. Six mice were subjected to gastric gavage with 52% Red Star Erguotou to establish the model, and six were given saline by gastric gavage as a control. After 28 days of modeling, 3 mice were randomly selected from each group. After deep anesthesia induced by inhalation of 3% isoflurane, the mice were sacrificed by cervical dislocation. The stomach, duodenum, jejunum, and rectum tissues were excised and immersed in 1% fluorescein sodium solution for staining. The microstructure of the mucosal surface of each tissue was observed using pCLE. The remaining mice in the model group and the control group were deeply anesthetized by inhaling 3% isoflurane, then cardiac perfusion was performed successively with saline and 4% paraformaldehyde. The stomach, duodenum, jejunum, and rectum tissues were excised for dehydration, section and hematoxylin-eosin (HE) staining, and the morphological changes of the tissues were observed under a microscope. ResultsUnder pCLE imaging, fluorescence staining on the surface of the gastrointestinal mucosa was uniform in the control group; the morphology of gastric pits, intestinal villi, and intestinal crypts was intact, arranged compactly, and had distinct boundaries. In the model group, the gastrointestinal mucosa exhibited mucosal swelling and deformation, with uneven fluorescence staining and fluorescein leakage. Furthermore, some tissues showed defects or cell shedding, and the boundaries between adjacent characteristic structures (e.g., gastric pits, intestinal crypts) were blurred. HE staining showed that the gastrointestinal tissue structure of the control group mice was normal and well-organized, with no structural defects. Moreover, submucosal glands were uniform in size, with no hyperplasia observed, and no obvious inflammatory cell infiltration. In the model group, some gastrointestinal mucosal structures were defective and sparsely arranged; submucosal glands showed atrophy, accompanied by obvious inflammatory cell infiltration. The histological characteristics detected by pCLE were consistent with those of HE staining. ConclusionpCLE can be used to obtain rapid, real-time, large-scale, and high-resolution microscopic imaging of the gastrointestinal mucosa, realistically and comprehensively displaying its physiological and microstructural characteristics. It shows promising prospects and practical utility in the histological evaluation of digestive system injuries in small animals.

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.

Objective:To explore the correlation between serum 1, 5-anhydroglucitol (1, 5-AG) and mild cognitive impairment (MCI) in elderly patients with type 2 diabetes mellitus (T2DM).Methods:A total of 160 patients with T2DM aged 60-75 years old who visited the First Hospital of Hebei Medical University from May 2021 to July 2022 were selected. According to the Montreal cognitive assessment (MoCA), all patients were divided into T2DM with MCI group (T2DM+ MCI group, n=81) and T2DM without MCI group (T2DM group, n=79). All research subjects were tested for glycated hemoglobin A1c (HbA1c), serum 1, 5-AG, serum β-amyloid peptide 42 (Aβ42), and blood biochemical indicators.SPSS 25.0 statistical software was used for data analysis. The t test, Mann-Whitney U test and χ2 test were used to compare the two groups. Binary Logistic regression analysis was used to examine the relevant influencing factors. Results:(1) Compared with T2DM group, patients in T2DM+ MCI group had significantly higher age, systolic pressure and HbA1c(all P<0.05).The level of 1, 5-AG in T2DM+ MCI group was significantly lower than that in T2DM group( (15.65±2.56 )μg/mL, (18.17±3.72 )μg/mL, P<0.01), and the level of Aβ42 was higher than that of T2DM group (2.95 (3.36) pg/mL, 1.91 (2.48) pg/mL, P<0.05). (2) Binary Logistic regression analysis results showed that HbA1c( β=0.230, OR=1.259, 95% CI=1.010-1.568, P=0.040) and Aβ42( β=0.188, OR=1.206, 95% CI=1.033-1.409, P=0.018) were the independent risk factors for MCI in elderly patients with T2DM, while 1, 5-AG ( β=-0.240, OR=0.786, 95% CI=0.698-0.886, P<0.001) was the protective factor for MCI. Conclusion:There is a positive correlation between serum 1, 5-AG and cognitive function, and the decrease of 1, 5-AG level was associated with the increased risk of MCI in elderly patients with T2DM.

Objective To investigate the value of serum chitinase-3-like protein 1 (CHI3L1) in predicting the risk of decompensation events in patients with liver cirrhosis, since prediction of decompensation events and adoption of active preventive measures are the key to improving the survival time of patients with liver cirrhosis. Methods A case-control study was conducted for 305 patients with liver cirrhosis who were diagnosed and treated in Tianjin Second People's Hospital from January 2019 to May 2021, among whom there were 200 patients with compensated liver cirrhosis and 105 patients with decompensated liver cirrhosis at baseline. According to whether decompensation events occurred within 1 year, the 305 patients with liver cirrhosis were divided into decompensation group with 79 patients and non-decompensation group with 226 patients; according to whether decompensation events occurred for the first time within 1 year, the 200 patients with compensated liver cirrhosis were divided into first-time decompensation group with 43 patients and non-first-time decompensation group with 157 patients. The independent samples t -test or the Mann-Whitney U test was used for comparison of normally distributed continuous data between groups, and the Wilcoxon rank-sum test or the chi-square test was used for comparison of categorical data between groups. The binary logistic regression analysis was used to investigate the association between each variable and decompensation events; the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC) were used to investigate the value of each variable in predicting decompensation events, and the maximum value of Youden index was used to determine the optimal cut-off value. Results The patients who experienced decompensation events within 1 year had a significantly higher baseline serum level of CHI3L1 than those who did not experience such events [243.00 (136.00-372.00) ng/mL vs 117.50 (67.75-205.25) ng/mL, U =4720.500, P < 0.001], and the patients who experienced decompensation events for the first time within 1 year had a significantly higher baseline serum level of CHI3L1 than those who did not experience such events [227.98 (110.00-314.00) ng/mL vs 90.00 (58.00-168.50) ng/mL, U =1 681.500, P < 0.001]. Patients with cirrhosis with higher baseline CHI3L1 levels had an increased risk of decompensation events within 1 year ( OR =1.004, 95% CI : 1.002-1.006, P < 0.001); Patients with compensated cirrhosis with higher baseline serum CHI3L1 levels had an increased risk of first decompensated event within 1 year ( OR =1.006, 95% CI : 1.003-1.008, P < 0.001). The baseline serum level of CHI3L1 had an AUC of 0.751 in predicting the risk of first-time decompensation events, with a sensitivity of 90.7% and a specificity of 55.4% at the optimal cut-off value of 95.5 ng/mL. The predictive model based on the combination of serum CHI3L1 level and Child-Pugh class had an AUC of 0.809, with a sensitivity of 72.1% and a specificity of 77.1% at the maximum value of Youden index. Conclusion Serum CHI3L1 level can be used as an effective predictive factor for the risk of first-time decompensation events in patients with compensated liver cirrhosis, and its combination with Child-Pugh class shows a higher predictive value.

Most information used to evaluate diabetic statuses is collected at a special time-point, such as taking fasting plasma glucose test and providing a limited view of individual's health and disease risk. As a new parameter for continuously evaluating personal clinical statuses, the newly developed technique "continuous glucose monitoring" (CGM) can characterize glucose dynamics. By calculating the complexity of glucose time series index (CGI) with refined composite multi-scale entropy analysis of the CGM data, the study showed for the first time that the complexity of glucose time series in subjects decreased gradually from normal glucose tolerance to impaired glucose regulation and then to type 2 diabetes (P for trend < 0.01). Furthermore, CGI was significantly associated with various parameters such as insulin sensitivity/secretion (all P < 0.01), and multiple linear stepwise regression showed that the disposition index, which reflects β-cell function after adjusting for insulin sensitivity, was the only independent factor correlated with CGI (P < 0.01). Our findings indicate that the CGI derived from the CGM data may serve as a novel marker to evaluate glucose homeostasis.

Objective:To evaluate the role of signal transducer and activator of transcription 3 (STAT3)/nuclear receptor coactivator 4 (NCOA4)-mediated ferritinophagy in salidroside-induced attenuation of intestinal ischemia-reperfusion (I/R) injury in mice and the relationship with ferroptosis.Methods:Thirty-six SPF-grade healthy male C57BL mice, aged 6-8 weeks, weighing 20-25 g, were divided into 6 groups ( n=6 each) by a random number table method: sham operation group (S group), sham operation+ salidroside group (SS group), intestinal I/R group (IR group), intestinal I/R+ salidroside group (IS group), intestinal I/R+ salidroside+ autophagy activator rapamycin group (ISR group) and intestinal I/R+ salidroside+ STAT3 activator colivelin group (ISC group). The intestinal I/R injury model was established by clamping the superior mesenteric artery for 45 min followed by 30-min reperfusion in IR, IS, ISR and ISC groups, while the superior mesenteric artery was only isolated without clipping in S and SS groups. At 1 week before developing the model, salidroside 40 mg/kg was intraperitoneally injected once a day for 7 consecutive days in SS, IS, ISC and ISR groups, rapamycin 4 mg/kg was intraperitoneally injected once a day for 7 consecutive days in group ISR, colivelin 1 mg/kg was intraperitoneally injected once a day for 7 consecutive days in group ISC, while the equal volume of normal saline was given instead in the rest two groups. The mice were sacrificed at 30 min of reperfusion, and intestinal tissues were obtained for examination of the pathological changes after HE staining (with a optical microscope) which were scored according to Chiu and for determination of contents of malondialdehyde (MDA), Fe 2+, glutathione (GSH) and reactive oxygen species (ROS), activity of superoxide dismutase (SOD) and expression of p-STAT3, STAT3, glutathione peroxidase 4 (GPX4), NCOA4 and ferritin heavy chain 1 (FTH1) in intestinal tissues (by Western blot). Results:Compared with group S, the Chiu′s score and contents of MDA, Fe 2+ and ROS were significantly increased, the content of GSH was decreased, the activity of SOD was decreased, the expression of p-STAT3 and NCOA4 was up-regulated, the expression of GPX4 and FTH1 was down-regulated, the p-STAT3/STAT3 ratio was increased ( P<0.05), pathological injury was found in intestinal tissues, and no significant change was found in the aforementioned indexes in group IR( P>0.05). Compared with group IR, the Chiu′s score and contents of MDA, Fe 2+ and ROS were significantly decreased, GSH content was increased, SOD activity was increased, the expression of p-STAT3 and NCOA4 was down-regulated, the expression of GPX4 and FTH1 was up-regulated, p-STAT3/STAT3 ratio was decreased ( P<0.05), and the pathological injury was significantly alleviated in intestinal tissues in group IS. Compared with group IS, the Chiu′s score and contents of MDA, Fe 2+ and ROS were significantly increased, GSH content was decreased, SOD activity was decreased, the expression of p-STAT3 and NCOA4 was up-regulated, the expression of GPX4 and FTH1 was down-regulated, p-STAT3/STAT3 ratio was increased ( P<0.05), and the pathological injury was aggravated in intestinal tissues in ISR and ISC groups. There was no statistically significant difference in the expression of STAT3 among the five groups ( P>0.05). Conclusions:STAT3/NCOA4-mediated ferritinophagy is involved in the process of salidroside-induced reduction of intestinal I/R injury in mice, which may be related to inhibiting ferroptosis.
