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:Migraine and tremor share some genetic mutation sites,and clinical studies have also confirmed their correlation.This study aims to explore the clinical and electrophysiological characteristics of migraine patients with concomitant tremor,and to analyze the relevant influential factors of tremor occurrence. Methods:We retrospectively analyzed the clinical data of 217 migraine patients who visited the Third Affiliated Hospital of Qiqihar Medical University from June 2022 to October 2023.The Clinical Rating Scale for Tremor(CRST),Numerical Rating Scale(NRS),Generalized Anxiety Disorder-7(GAD-7),and Patient Health Questionnaire-9(PHQ-9)were respectively used to assess the tremor symptoms,degree of headache,anxiety,and depression of patients.All patients underwent routine head MR scanning and electromyography examination,and were divided into a migraine with tremor group and a migraine without tremor group based on the electromyogram examination. Results:The migraine with tremor group and the migraine without tremor group were included 52 patients(23.96%)and 165 patients(76.04%),respectively.Compared with the migraine without tremor group,the migraine with tremor group had a longer course and duration of headache,higher frequency of headache attacks,higher NRS score,GAD-7 score,and PHQ-9 score,and fewer weekly physical exercises.The differences were statistically significant(all P<0.05).There were no statistically significant differences in the presence or absence of prodromal headache and white matter hyperintensities(WMHs)between the 2 groups(both P>0.05).The evaluation results of the CRST showed that out of 217 migraine patients,39 patients(17.97%)were accompanied by tremors.The electromyographic results showed that all 52 migraine patients with tremors had upper limb tremors,including 28 migraine patients with postural tremors and 24 migraine patients with static tremors.Compared with the migraine patients with static tremors,the migraine patients with postural tremors had lower average frequency,peak frequency,and headache onset frequency(all P<0.05).Multiple linear regression analysis showed that frequency of physical exercise,duration of illness,frequency of headache attacks,NRS score,GAD-7 score,and PHQ-9 score were risk factors for migraine patients with concomitant tremors(all P<0.05). Conclusion:Patients with migraine mainly experience upper limb postural tremors.Reduced physical exercise,long course of disease,long duration of headache,frequent headache attacks,severe headache,anxiety,and depression are risk factors for migraine patients with concomitant tremors.

ObjectiveAlveolar macrophages (AMs) are critical for maintaining the homeostasis of pulmonary microenvironment. They process surfactants to ensure alveoli patency, and also serve as the first line of immune defense against pathogen invasion. Available studies have shown that monocyte-derived AMs continuously release pro-inflammatory cytokines and chemokines, recruiting other immune cells to the damaged area during pulmonary fibrosis. These monocyte-derived AMs maintains and amplifies inflammation, playing a negative role in pulmonary fibrosis progression. Current researches have predominantly focused on the gene expression levels of AMs in pulmonary fibrosis microenvironment, with less emphasis on the function and regulation of proteins. This study aims to investigate the differentially expressed proteins (DEPs) of AMs under normal physiological conditions and after pulmonary fibrosis, in order to gain a more comprehensive understanding of the role of AMs in the progression of pulmonary fibrosis. MethodsFirstly, the construction of bleomycin-induced pulmonary fibrosis mouse models was evaluated through using measurements such as body mass, lung coefficient, lungwet-to-dry mass ratio, H&E staining and Masson staining. Subsequently, AMs from both the saline controls and the pulmonary fibrosis models (2.5×10⁵ cells per sample) were collected using FACS sorting, and protein expression profiles of these cells were obtained through label-free proteomics approach. The quality of the proteomic data was assessed by comparing our saline control proteomic data with public proteomic data of physiological AMs. Thirdly, DEPs analysis between the saline controls and the bleomycin groups was carried out using R package Prostar. Functional enrichment analyses of significantly upregulated DEPs were performed using R package Clusterprofiler for GO and KEGG pathways. Finally, the STRING database was used to explore the protein-protein interaction networks related to phagocytosis regulation, inflammatory response regulation, andI-κB/NF-κB signaling pathway. The expression levels of Tlr2 and Pycard were detected respectively by FACS and western blotting. ResultsCompared to the saline controls, mice in the bleomycin groups exhibited a lower average body mass, extensive infiltration of inflammatory cells, and deposition of collagen in the lungs. This indicates that bleomycin successfully induced pulmonary fibrosis in mouse models. The proteomic data of AMs obtained from these models was of high quality and fulfilled the research requirements. A comprehensive analysis showed that 778 proteins were upregulated in pulmonary fibrosis groups compared with control groups. Moreover, the signal pathways enriched in up-regulated DEPs were related to the I‑κB/NF‑κB pathway, inflammatory response regulation, phagocytosis regulation, TGF-β signaling, and HIF-1 pathway, indicating that AMs in pulmonary fibrosis microenvironment exerted pro-inflammatory and pro-fibrotic functions. Protein-protein interaction network analysis of the DEPs suggested that the interactions between Tlr2 and Pycard were control nodes for the pro-inflammatory phenotype of AMs, thereby contributing to pulmonary fibrosis progression. Further validation by FACS and Western blotting respectively confirmed that the expression levels of Tlr2 and Pycard in AMs were significantly increased after pulmonary fibrosis. ConclusionThis study investigates the changes in the protein expression profile of AMs in the pulmonary fibrosis microenvironment. The results show that AMs notably enhanced the activity of various pathways associated with inflammation and fibrosis, suggesting that the interaction between Tlr2 and Pycard serves as a key control node for the highly pro-inflammatory behavior of AMs.

Objective To investigate the clinical efficacy of therapy of clearing heat,percolating dampness and lowering turbidity combined with Silibin Meglumine Tablets in the treatment of non-alcoholic steatohepatitis(NASH)patients with abnormal alanine aminotransferase(ALT)level of damp-heat accumulation type.Methods A retrospective study was conducted.According to the medication,80 patients with NASH with abnormal ALT level of damp-heat accumulation type were divided into control group and observation group,with 40 cases in each group.The control group was treated with Silibin Meglumine Tablets,and the observation group was treated with therapy of clearing heat,percolating dampness and lowering turbidity on the basis of treatment for the control group.The course of treatment covered 12 weeks.The changes of liver function indicators of ALT,aspartate aminotransferase(AST),and gamma glutamyl transpeptidase(GGT),blood lipid indicators of total cholesterol(CHOL)and triglyceride(TRIG),and the degree of hepatic steatosis in the two groups were observed before and after treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After 12 weeks of treatment,the total effective rate of the observation group was 95.00%(38/40),and that of the control group was 77.50%(31/40).The curative effect of the observation group was significantly superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the levels of ALT,AST and GGT in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of ALT,AST and GGT in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the levels of CHOL and TRIG in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of CHOL and TRIG in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the degree of hepatic steatosis in the two groups was significantly lower than that before treatment(P＜0.05),and the decrease of the degree of hepatic steatosis in the observation group was significantly superior to that in the control group(P＜0.05).(5)During the treatment,no obvious adverse reactions occurred in the two groups,indicating high safety.Conclusion The therapy of clearing heat,percolating dampness and lowering turbidity combined with Silibin Meglumine Tablets exerts certain effect in the treatment of NASH patients with abnormal ALT level of damp-heat accumulation type,and the therapy can significantly enhance the clinical efficacy of Silibin Meglumine Tablets alone for NASH.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the impacts of different levels(1,3 and 5)of iDream reconstruction on CT quantitative analysis of lung function parameters,providing references for quantitative measurement of emphysema indicators by iDream reconstruction technology.Methods A retrospective study was performed for 50 patients who underwent noncontrast chest CT scan in some hospital from December 2021 to January 2022,and the images were reconstructed using four methods:fittered back projection(FBP)and level 1,3 and 5 iDream techniques.For the four groups of images,the main tracheal CT values and standard deviation(SD)values were measured,the signal to noise ratio(SNR)was calculated and the total lung volume(TLV),emphysema volume(EV),emphysema index(EI),15th percentile of lung attenuation(Perc 15)and pulmonary density 15％(PD15％)were detected with quantitative lung function analysis software.Statistical analysis was performed using SPSS 24.0 software.Results The four groups did not have significant differences in the main tracheal CT value and TLV(P＞0.05),while did in SD,SNR,EV,EI,PD15％and Perc 15(P＜0.05).As the reconstruction level of iDream increased,the main tracheal SD value,EV and EI decreased gradually,and level 3 and 5 iDream reconstruction groups had no significant differences in EV and El(P＞0.05);as the reconstruction level of iDream increased,PD15％and Perc 15 rose gradually,and level 3 and 5 iDream reconstruction groups had no significant differences in PD15％and Perc 15(P＞0.05).Conclusion Increase of the level of iDream reconstruction algorithm affects the results of CT quantitative analysis of lung function by reducing image noise.Level 3 and 5 iDream reconstruction ensures the stability of EV,EI,PD15％and Perc 15,which are not influenced by the strength of the iterative reconstruction algorithm.[Chinese Medical Equipment Journal,2024,45(9):57-61]

AIM: To investigate the relationship among the fasting plasma glucose coefficient of variation(FPG-CV)and macular morphology and microcirculation in patients with nonproliferative diabetic retinopathy(NPDR).METHODS: A retrospective analysis of 82 cases(82 eyes)with NPDR admitted to our hospital from February 2018 to June 2022 was the research object, and another 82 cases(82 eyes)of non-diabetic retinopathy(NDR)patients during the same period were selected as the control group, and the clinical data of the two groups of patients were analyzed. Multivariate Logistic regression was used to analyze the risk factors affecting the incidence of NPDR, and the back propagation(BP)neural network model was established and evaluated. Pearson correlation was used to analyze the correlation among FPG-CV and macular morphology and microcirculation in patients. RESULTS: The results of multivariate Logistic regression analysis showed that the disease duration ≥7.2a, glycated hemoglobin A1c(HbA1c)≥7.7%, triglyceride(TG)≥1.9 mmol/L, microalbuminuria(MALB)≥24.5 mg/L, FPG-CV ≥9.8%, superficial capillary plexus-vessel density(SCP-VD)<27.6%, deep capillary plexus-vessel density(DCP-VD)<47.7%, foveal avascular zone(FAZ)area ≥0.38 mm2, central retinal thickness(CRT)≥197.7 μm and subfoveal choroidal thickness(SFCT)<227.7 μm were risk factors for NPDR(P<0.05). The number of hidden layer nodes is 5, and the receiver operating characteristic(ROC)curve, calibration curve and clinical decision curve show that the prediction model has good discrimination, accuracy and validity. The results of Pearson correlation analysis showed that FPG-CV was negatively correlated with SCP-VD, DCP-VD and SFCT(P<0.05); FPG-CV was positively correlated with FAZ area and CRT(P<0.05).CONCLUSION: The course of disease, HbA1c, TG, MALB, FPG-CV, SCP-VD, DCP-VD, FAZ area, CRT and SFCT are all related to the pathogenesis of NPDR. With the increase of FPG-CV, the indexes of macular morphology and microcirculation changed. FPG-CV was negatively correlated with SCP-VD, DCP-VD and SFCT and positively correlated with FAZ area and CRT.
