Patients with liver cirrhosis are more susceptible to various bacterial or viral infections due to immune dysfunction. Recent studies have shown that compared with the general population， individuals with liver cirrhosis show a significant increase in the incidence rate of adverse outcomes after severe acute respiratory syndrome coronavirus 2 infection， including the progression of liver injury and the increase in mortality rate. Vaccination can reduce the incidence rates of breakthrough infections and severe coronavirus disease 2019 （COVID-19） in patients with liver cirrhosis， but such patients have low immune response and thus require booster doses to enhance immunity. This article reviews the clinical features of cirrhotic patients with COVID-19 and related management strategies， in order to provide evidence-based guidance for the clinical diagnosis and treatment of such patients.

Objective: To assess the association of family food environment with dietary and nutrition literacy among junior and senior high school students, providing a basis for nutritional health education and adolescent nutritional improvement. Methods: From January 9 to February 10, 2025, a total of 1 473 junior and senior high school students aged 12-20 were recruited by using a cluster random sampling method combined with convenient sampling from 15 provinces (municipalities and autonomous regions) across China. Data on basic demographic characteristics, home food environment, and dietary and nutrition literacy were collected by using the Food and Nutritional Literacy Questionnaire for Chinese School age Children. Multiple linear regression and Logistic regression models were employed to analyze the association of the home food environment on adolescent dietary and nutrition literacy. Results: The total score of dietary and nutrition literacy among junior and senior high school students was (65.28±9.03). The score in the cognitive domain (67.59±10.56) was higher than that in the skill domain (60.74±9.15), and the score for food preparation skills (56.60±14.28) was the lowest. Students aged 16-20, senior high school students, those for only children, non boarding students, those with urban household registration, those from wealthier families, those whose primary caregivers were parents with higher education levels, and those who previously received nutrition and health education had significantly higher dietary and nutrition literacy scores compared to their respective counterpart groups ( t/F =-8.32, -8.14, 4.76, -2.70, 7.15, 18.29, 10.68, 11.66 , all P <0.05). Multiple linear regression analysis revealed that family food environment was associated with dietary and nutrition literacy, and the model was statistically significant ( R 2=0.20, F=20.54, P <0.05). Lower availability of fruits at home in the past month and lower frequency of family communication regarding dietary and nutrition were associated with lower dietary nutrition literacy scores among junior and senior high school students ( β =-1.35, -1.67, both P <0.01). Among junior and senior high school students, lower frequency of dining out with the family, watching videos during family meals, and being urged by parents to eat more food in the past month were associated with higher scores on dietary nutrition literacy ( β =1.35, 1.13, 0.71, all P <0.01). Logistic regression model results indicated that watching videos during family meals ( OR =1.70) and family communication regarding dietary and nutrition ( OR =0.51) were significantly associated with dietary and nutrition literacy levels (both P <0.05). Conclusions The score of dietary and nutrition literacy among junior and senior high school students is relatively low, and the family food environment is a key factor. It is recommended that nutrition education and improvement initiatives for junior and senior high school students prioritize attention on children and adolescents from households with less favorable food environments.

ObjectiveTo investigate the mechanism of Hei Xiaoyaosan （HXS） in ameliorating cognitive impairment in the rat model of Alzheimer's disease （AD） by regulating the adenosine 5'-monophosphate-activated protein kinase （AMPK）/sterol regulatory element-binding protein 2 （SREBP2）/proprotein convertase subtilisin/kexin type 9 （PCSK9）/low-density lipoprotein receptor-related protein 1 （LRP-1） signaling pathway to clear amyloid-β （Aβ） from the peripheral circulation. MethodsNinety 8-week-old specific pathogen-free （SPF）-grade male Sprague-Dawley （SD） rats were acclimatized for 1 week. After acclimatization， 10 rats were randomly selected as the blank control group， and the remaining 80 rats were prepared for surgical modeling. Among the 80 rats for modeling， 70 were anesthetized and injected with 1 μL of amyloid-β_1-42 （Aβ_1-42） solution into the bilateral hippocampal CA1 region for the modeling of AD， and the remaining 10 were assigned to the sham operation group， which received an injection of 1 μL normal saline at the same anatomical site. The successfully modeled rats were randomly assigned into 6 groups （n=10 per group）： a model group， a donepezil hydrochloride group， an acadesine （AICAR， an AMPK agonist） group， and high-， medium-， and low-dose HXS groups. After 42 consecutive days of administration intervention， the Morris water maze test and T-maze test were performed to evaluate the learning and memory abilities of rats. Fluoro-Jade B （FJB） staining was conducted to observe pathological changes of neurons in the rat hippocampus， and thioflavin S staining to quantify the area of Aβ deposition in the hippocampal region. Immunofluorescence double staining （IF-DS） was performed to detect the expression of LRP-1 and Aβ signals in the liver tissue. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of Aβ_1-42 and soluble LRP-1 （sLRP-1） in the serum. Western blot was performed to determine the protein levels of AMPK， phosphorylated AMPK （p-AMPK）， SREBP2， PCSK9， and LRP-1 in the liver tissue. Real time polymerase chain reaction（Real-time PCR） was adopted to assess the mRNA levels of AMPK， SREBP2， PCSK9， and LRP-1 in the liver tissue. ResultsCompared with the blank control group， the model group showed increased total swimming distance on day 6 and path length in the target quadrant on day 7 （P<0.01）， a decreased correct alternation rate in the T-maze test （P<0.01）， disarrangement of hippocampal neurons， increased FJB-positive cells （P<0.01）， enlarged area of Aβ deposition （P<0.01）. reduced LRP-1 fluorescence signals and enhanced Aβ fluorescence signals in the liver tissue （P<0.01）， elevated serum level of Aβ_1-42， declined serum level of sLRP-1 （P<0.01）， downregulated protein levels of p-AMPK and LRP-1 as well as mRNA levels of AMPK and LRP-1， and upregulated protein and mRNA levels of SREBP2 and PCSK9 in the liver tissue （P<0.01）. Compared with the model group， the high-dose HXS group， donepezil hydrochloride group， and AICAR group exhibited reduced total swimming distance and target quadrant path length （P<0.05， P<0.01）， an increased correct alternation rate in the T-maze test （P<0.05）， decreased FJB-positive cells （P<0.01）， reduced Aβ deposition （P<0.01） in the hippocampal tissue， enhanced LRP-1 signals and weakened Aβ signals in the liver tissue （P<0.01）， a declined serum level of Aβ_1-42 and an elevated serum level of sLRP-1 （P<0.01）， upregulated protein levels of p-AMPK and LRP-1 as well as mRNA levels of AMPK and LRP-1， and downregulated protein and mRNA levels of SREBP2 and PCSK9 in the liver tissue （P<0.01）. ConclusionHei Xiaoyaosan can regulate the AMPK/SREBP2/PCSK9/LRP-1 signaling pathway to enhance the clearance of peripheral Aβ by the liver tissue and reduce Aβ deposition in the brain， thereby improving the learning and memory abilities of AD rats.

Compared with the model group， the positive control group and the high-dose Hei Xiaoyaosan group exhibited shortened escape latency （P<0.01）， an increased percentage of retention time in the target quadrant， an increased alternation response rate （P<0.05， P<0.01）， alleviated neuronal shrinkage， regular morphology and arrangement of neurons in the hippocampal tissue， lowered levels of p-tau and Aβ in the hippocampal tissue （P<0.05， P<0.01）， declined levels of IL-1β， IL-18， and Aβ_1-42， downregulated mRNA and protein levels of AEP， tau， α-Syn， TLR2， and NLRP3， and downregulated protein levels of p-tau and p-α-Syn （P<0.05， P<0.01）. ConclusionHei Xiaoyaosan can protect hippocampal neurons and ameliorate cognitive impairment in the rat model of AD. Specifically， it may inhibit AEP to regulate tau phosphorylation， Aβ deposition， and neuroinflammation.

ObjectiveTo investigate the effects of Hei Xiaoyaosan on neuroinflammation in APP/PS1 mice and decipher the mechanism based on the C-X3-C chemokine ligand 1 （CX3CL1）-CX3CL1 receptor 1 （CX3CR1） signaling axis. MethodsSixty 16-week-old male APP/PS1 mice were selected and acclimatized for one week， and they were then randomly allocated into a model group， a CX3CL1 group （bilateral hippocampal injection of CX3CL1 at 0.5 g·L^-1）， and high-， medium-， and low-dose （22.10， 11.05， and 5.53 g·kg^-1， respectively） Hei Xiaoyaosan groups， with 12 mice in each group. Twelve age-matched male C57BL/6J mice served as the blank group （bilateral hippocampal injection of an equal volume of PBS）. The high-， medium-， and low-dose Hei Xiaoyaosan groups received corresponding drugs via gavage， while the blank group received an equal volume of normal saline， with an intervention period of 90 days. Morris water maze was used to assess learning and memory abilities. Nissl staining was performed to observe the pathological changes in neurons of the hippocampal CA1 region. Immunohistochemistry was adopted to detect amyloid-β_1-42 （Aβ_1-42） deposition in the hippocampal CA1 region. The immunofluorescence assay was employed to detect the expression of M1 and M2 microglial markers， including cluster of differentiation 86 （CD86）/ionized calcium-binding adapter molecule 1 （Iba-1） and arginase-1 （Arg1）/Iba1. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of interleukin-8 （IL-8） and interleukin-13 （IL-13） in the hippocampal tissue. Western blot was employed to determine the protein levels of CX3CL1， CX3CR1， CREB-binding protein （CBP）， cyclic AMP response element-binding protein （CREB）， phosphorylated （p）-CREB， and brain-derived neurotrophic factor （BDNF） in the hippocampal tissue. ResultsCompared with the blank group， the model group exhibited prolonged escape latency on day 5 and a reduced swimming distance in the target quadrant （P<0.01）， disarrangement of hippocampal neurons， with a reduced number of cells and uneven Nissl body staining， increased CD86/Iba1 expression， decreased Arg1/Iba1 expression （P<0.01）， enhanced Aβ expression （P<0.01）， an elevated IL-8 level and a declined IL-13 level （P<0.01）， and downregulated protein levels of CX3CL1， CX3CR1， CBP， p-CREB， and BDNF （P<0.01）. Compared with the model group， all treatment groups showed shortened escape latency on day 5 and an increased swimming distance in the target quadrant （P<0.05， P<0.01）， regular arrangement of neurons with an increased number and increased Nissl bodies， reduced CD86/Iba1 expression， increased Arg1/Iba1 and decreased Aβ expression （P<0.01）， and a declined IL-8 level and an elevated IL-13 level （P<0.05， P<0.01）. In the CX3CL1 group and the high- and medium-dose Hei Xiaoyaosan groups， the relative expression levels of CX3CL1， CX3CR1， CBP， and p-CREB were upregulated （P<0.01）. In the low-dose Hei Xiaoyaosan group， the relative expression levels of CX3CL1， CX3CR1， CBP， p-CREB/CREB， and BDNF were upregulated （P<0.05， P<0.01）. ConclusionHei Xiaoyaosan can improve learning and cognitive abilities in APP/PS1 mice. Specifically， it may regulate the CX3CL1/CX3CR1 signaling axis to activate the CREB/BDNF signaling pathway for the subsequent release of BDNF， modulation of microglial polarization， reduction of inflammatory cytokine levels， and attenuation of Aβ deposition.

ObjectiveTo investigate the effect and mechanism of Hei Xiaoyaosan in preventing and treating Alzheimer's disease （AD） by activating autophagy through regulating the adenosine monophosphate-activated protein kinase （AMPK）/UNC-51 like autophagy activating kinase 1 （ULK1） signaling pathway. MethodsNinety 8-week-old male SPF-grade SD rats were selected and randomized into two groups： a blank control group （n=10） and a modeling group （n=80）. From the modeling group， 10 rats were randomly assigned as a sham group （bilateral hippocampal injection of 1 μL normal saline）， while the remaining 70 rats were injected with 1 μL Aβ_1-42 solution bilaterally into the hippocampus to replicate the AD model. The Morris water maze test was conducted to screen the successfully modeled rats， which were then randomly allocated to the model， donepezil hydrochloride， 5-aminoimidazole-4-carboxamide 1-β-D-ribofuranoside （AICAR， an AMPK agonist）， and high-， medium-， and low-dose Hei Xiaoyaosan groups， with 10 rats per group. After 42 days of drug intervention， the Morris water maze and open field tests were conducted to assess learning and memory abilities and motor function. Pathological changes in the hippocampal tissue were observed by Nissl staining， and autophagy-related pathological damage was examined via transmission electron microscopy （TEM）. The expression of LC3 in the hippocampus was observed by immunofluorescence staining. The protein levels of AMPK， phosphorylate （p）-AMPK， ULK1， p-ULK1， p62， and autophagy related 7 （Atg7） were determined by Western blot， while the mRNA levels of AMPK and ULK1 were measured by Real-time polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank control group， the model group showed increased escape latency （P<0.01） and decreased platform crossings （P<0.01） on day 6 in the water maze test， reduced total distance traveled and average speed in the open field test （P<0.01）， disarranged neurons with Nissl body loss and evident autophagic damage， weakened LC3 fluorescence signal （P<0.01）， downregulated protein levels of p-AMPK， p-ULK1， and Atg7 and mRNA levels of AMPK and ULK1 in the hippocampus （P<0.01）， and upregulated protein level of p62 （P<0.01）. Compared with the model group， the positive drug group， high-dose Hei Xiaoyaosan group， and AICAR group showed decreased escape latency （P<0.05， P<0.01） and increased platform crossings （P<0.01） on day 6， and increased total distance traveled and average speed in the open field test （P<0.05）. The positive drug group， high- and medium-dose Hei Xiaoyaosan groups， and the AICAR group showed alleviated cellular structural damage， regular neuronal arrangement， increased Nissl bodies， and orderly distribution of autophagosomes. Furthermore， the LC3 fluorescence intensity was enhanced in the positive drug group， high- and medium-dose Hei Xiaoyaosan groups， and the AICAR group （P<0.01）. The positive drug group， high-dose Hei Xiaoyaosan group， and the AICAR group exhibited upregulated protein and mRNA levels of p-AMPK and p-ULK1 （P<0.05， P<0.01）， upregulated protein level of Atg7 （P<0.05， P<0.01）， and downregulated protein level of p62 （P<0.01）. ConclusionHei Xiaoyaosan can improve learning and memory abilities and alleviate pathological status in the rat model of AD by regulating the AMPK/ULK1 signaling pathway， enhancing cellular autophagy， and repairing damaged nerve cells.

To target the pivotal BCR/ABL oncoprotein in chronic myeloid leukemia (CML) cells, tyrosine kinase inhibitors (TKIs) are utilized as landmark achievements in CML therapy. However, TKI resistance and intolerance remain principal obstacles in the treatment of CML patients. In recent years, drug repositioning provided alternative and promising perspectives apart from the classical cancer therapies, and promoted anthelmintic mebendazole (MBZ) as an effective anti-cancer drug in various cancers. Here, we investigated the role of MBZ in CML treatment including imatinib-resistant CML cells. Our results proved that MBZ inhibited the proliferation and induced apoptosis in CML cells. We found that MBZ effectively suppressed BCR/ABL kinase activity and MEK/ERK signaling pathway by reducing p-BCR/ABL and p-ERK levels with ABL1 targeting ability. Meanwhile, MBZ directly targeted the colchicine-binding site of β-tubulin protein, hampered microtubule polymerization and induced mitosis arrest and mitotic catastrophe. In addition, MBZ increased DNA damage levels and hampered the accumulation of ataxia-telangiectasia mutated and DNA-dependent protein kinase into the nucleus. This work discovered that anthelmintic MBZ exerts remarkable anticancer effects in both imatinib-sensitive and imatinib-resistant CML cells in vitro and revealed mechanisms underlying. From the perspective of drug repositioning and multi‐target therapeutic strategy, this study provides a promising option for CML treatment, especially in TKI-resistant or intolerant individuals.

To summarize Professor GAO Shuzhong's clinical experience in treating idiopathic tinnitus with a combination of acupuncture and Chinese meteria medica. It is believed that idiopathic tinnitus is mostly caused by weak lungs and spleen， kidney essence deficiency， liver constraint transforming into fire， and binding constraint of heart qi. Treatment advocates the combination of acupuncture and Chinese meteria medica in clinical practice. Acupuncture treatment mainly focus on the method of opening the orifices by syndrome identification in combination with Ermen （TE 21）， Tinggong （SI 19）， Tinghui （GB 2）， Shenmai （BL 62） to regulate qi and blood， and supporting with Baihui （GV 20）， Yintang （EX-HN 3）， Taichong （LR 3）， and Yanglingquan （GB 34） to soothe the liver， resolve constraint， and calm the mind. Oral administration of Chinese medicinal prescription usually includes modified Yiqi Congming Decoction （益气聪明汤） and Tongqi Powder （通气散）， and the external administration of Chinese medicinal prescription can apply self-prescribed Wenqing Powder （温清散） to navel moxibustion.

Objective:Exploration of the immunogenicity and persistence of three different immunization regimens of hepatitis B vaccines in diabetic patients.Methods:Participants with diabetes and non-diabetic individuals were recruited from study sites and assigned to different vaccination regimens: the diabetic group (①D60Yeast0-1: received 60 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-month schedule; ②D20Yeast0-1-6: received 20 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-6-month schedule; ③D20CHO0-1-6: received 20 μg Chinese hamster ovary (CHO) cell-derived recombinant HBV vaccine on a 0-1-6-month schedule) and the non-diabetic group (ND20Yeast0-1-6: non-diabetic individuals received 20 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-6-month schedule). Venous blood samples were collected at 1,12, and 48 months post-full vaccination to measure anti-HBs levels. Differences in immunogenicity between diabetic and non-diabetic groups, as well as among diabetic subgroups, were analyzed.Results:This study enrolled a total of 564 subjects. In the D20CHO0-1-6 group, the seroconversion rate decreased from 90.72% (95% CI: 84.84%-96.60%) at 1 month to 74.23% (95% CI: 65.37%-83.08%) at 48 months, and the antibody geometric mean concentration (GMC) decreased from 676.08 (95% CI: 389.05- 1 148.20) mIU/ml at 1 month to 33.11 (95% CI: 23.44-46.77) mIU/ml at 48 months. In the D20Yeast0-1-6 group, the seroconversion rate declined from 93.81% (95% CI: 89.29%-98.32%) at 1 month to 63.72% (95% CI: 54.71%-72.72%) at 48 months, with antibody GMC dropping from 630.96 (95% CI: 407.40-954.99) mIU/ml to 25.70 (95% CI: 17.78-38.02) mIU/ml over the same period. For the D60Yeast0-1 group, seroconversion rate fell from 82.03% (95% CI: 75.29%-88.77%) to 56.25% (95% CI: 47.54%-64.96%), and antibody GMC decreased from 81.28 (95% CI: 51.29-128.82) mIU/ml to 15.49 (95% CI: 11.75-20.89) mIU/ml between 1 and 48 months. The ND20Yeast0-1-6 group (non-diabetic control) exhibited a higher initial seroconversion rate of 97.56% (95% CI: 94.80%- 100.00%) at 1 month, but it still declined to 76.42% (95% CI: 68.82%-84.03%) at 48 months, with antibody GMC decreasing from 1 318.30 (95% CI: 912.01- 1 905.50) mIU/ml to 34.67 (95% CI: 25.12-47.86) mIU/ml. Multivariate analysis on factors influencing the GMC of antibodies revealed statistically significant differences in antibody GMC between the D20Yeast0-1-6 group and ND20Yeast0-1-6 group at 12 months (a OR=0.73, 95% CI: 0.58-0.93) and 48 months (a OR=0.79, 95% CI: 0.63-0.99) post-vaccination (all P<0.05). As for the diabetic population, when compared with the D20Yeast0-1-6 group, the D60Yeast0-1 group also showed statistically significant differences in antibody GMC at 12 months (a OR=0.57, 95% CI: 0.44-0.74) and 48 months (a OR=0.60, 95% CI: 0.47-0.76)(all P<0.05). Conclusions:The seroconversion rate and antibody GMC gradually decreased over time (1, 12, and 48 months) in the four groups. Diabetic patients showed poor immunogenicity and persistence to hepatitis B vaccines. The immunogenicity and persistence of hepatitis B vaccination in diabetic patients were associated with vaccine type, antigen dose, and vaccination regimen. The CHO cell-recombinant hepatitis B vaccine demonstrated better performance in terms of immunogenicity and persistence among the diabetic population.
