Objective To systematically review international research on health communication, and to provide valuable insights and reference for China's health communication research and practice. Methods This study included 693 articles published from January 2023 to April 2024 in two authoritative academic journals in the field of health communication, ^“Health Communication^” and the ^“Journal of Health Communication^”. A systematic review was conducted on the themes, theoretical foundations, research methods, and populations of international health communication research. Results The findings in this study revealed that international health communication research topics were diverse, with hotspots including social media, health information behavior, health misinformation, stigmatization, trust, and risk perception. The results showed that 34% of the articles were based on theoretical foundations, and 93.3% employed research methods, focusing on adolescents, parents, women, and other key populations. Conclusion Domestic health communication research can expand its perspective from ^“information transmission^” to ^“social interaction^”, innovate theories and methods from ^“single paradigm" to ^“multi-integration^” and shift focus from a ^“mass perspective^” to ^“targeted care^” for the health of all populations. Domestic health communication practice can delve into the localization of social media health communication practices, the comprehensive management of health misinformation, and the critical application of new technologies.

Objective To understand the current situation of nutrition literacy of primary and secondary school students in Shijingshan District of Beijing, and analyze its influencing factors, and to put forward targeted suggestions for improving the students’ nutrition literacy and promoting their healthy growth. Methods A multi-stage stratified cluster sampling method was used to select 2480 primary and secondary school students and their parents from 5 primary schools, 3 middle schools and 1 high school in Shijingshan District. The multivariate logistic regression model was used to analyze the factors influencing the attainment rate of nutrition literacy. Results The median score of nutrition literacy of 2480 primary and secondary school students from grades 1 to 12 was 77.86 (in hundred-mark system), the quartile range (IQR) was 16.96, and the attainment rate of nutrition literacy was 42.46%. The cognitive level (45.12%) was higher than the skill level (41.20%) among students from grades 3 to 12. In terms of skills, the attainment rate of food preparation was the lowest, at 30.38%. The scores of nutrition literacy of girls were higher than those of boys, and the scores of primary school students were higher than those of secondary school students. Students with different levels of caregiver’s education, family income, and family food environment had different scores of nutrition literacy, and the differences were statistically significant (P<0.05). Multivariate logistic regression analysis showed that the attainment rate of nutrition literacy was closely related to student’s gender and study stage, caregiver’s education level, and family food environment. Conclusion The nutrition literacy of primary and secondary school students in Shijingshan District still needs to be improved, especially in the aspect of skills. Targeted nutrition education should be carried out.

Objective:To investigate the effects and possible mechanisms of targeted inhibition of Polo-like kinase 1 (PLK1) on the proliferation, mitosis and apoptosis of cervical cancer cells.Methods:Logarithmically growing human cervical cancer cell lines HeLa and C-33A were selected, and cells treated with 10 and 20 nmol/L PLK1 inhibitor GSK461364 were used as different concentrations of GSK461364 groups, while cells not treated with GSK461364 were used as the control group. CCK-8 method was used to detect cell proliferation ability (represented by absorbance values at wavelength 450 nm), flow cytometry was used to detect chromosome ploidy (propidium iodide staining), mitochondrial membrane potential detected by flow cytometry was used to evaluate cell apoptosis status (JC-1 fluorescent probe, the cells where the JC-1 monomers emitting green fluorescence were located were apoptotic cells), and Western blotting was used to detect the expression levels of cell cycle and apoptosis-related proteins.Results:The results of CCK-8 method showed that the proliferation ability of HeLa cells was lower than that of the control group after 24 hours of treatment with 10 and 20 nmol/L GSK461364 and continued culture for 24, 48 and 72 hours without GSK461364. The proliferation ability of C-33A cells was lower than that of the control group after 24 hours of treatment with 10 and 20 nmol/L GSK461364 and continued culture for 48 and 72 hours without GSK461364, and the differences were statistically significant (all P < 0.05). The results of flow cytometry analysis showed that after 24 hours of treatment with GSK461364 and continued culture for 72 hours without GSK461364, the proportions of polyploid cell subpopulations in HeLa cells of the 10 and 20 nmol/L GSK461364 groups and the control group were (13.89±3.73)%, (12.30±5.49)% and (9.86±1.15)%, respectively, with no statistically significant difference ( F = 0.82, P > 0.05); the proportions of polyploid cell subpopulations in C-33A cells of the 10 and 20 nmol/L GSK461364 groups and the control group were (8.45±2.20)%, (11.06±2.53)% and (5.42±1.36)%, respectively, with statistically significant difference ( F = 5.46, P = 0.045). Among them, the proportion of polyploid cell subpopulations in the 20 nmol/L GSK461364 group was higher than that in the control group, with statistically significant differences ( t = 3.40, P = 0.027). The results of flow cytometry detection of mitochondrial membrane potential showed that after 24 hours of treatment with GSK461364 and continued culture for 72 hours without GSK461364, the proportions of apoptotic cells in HeLa cells of the control group, 10 nmol/L GSK461364 group and 20 nmol/L GSK461364 group were (3.96±2.28)%, (24.38±4.89)%, and (46.24±4.38)%, respectively, and the difference was statistically significant ( F = 83.18, P < 0.000 1), the proportion of apoptotic cells in the 10 and 20 nmol/L GSK461364 groups was higher than that in the control group, and the difference was statistically significant (both P < 0.01), and the proportion of apoptotic cells in the 20 nmol/L group was higher than that in the 10 nmol/L group ( t = 5.76, P = 0.005); the proportions of apoptotic cells in C-33A cells of the control group, 10 nmol/L GSK461364 group and 20 nmol/L GSK461364 group were (1.81±1.59)%, (5.22±1.57)% and (15.87±5.81)%, respectively, with statistically significant differences ( F = 12.49, P = 0.007), and the proportion of apoptotic cells in the 20 nmol/L group was higher than that in the 10 nmol/L group and the control group (both P < 0.05). The results of Western blotting analysis showed that after 24 hours of treatment with GSK461364 and continued culture for 72 hours without GSK461364, the relative expression levels of cleaved Caspase-9 and cleaved polyadenosine diphosphate-ribose polymerase in HeLa and C-33A cells treated with 10 and 20 nmol/L GSK461364 were higher than those in the control group, and the relative expression levels of cdc25c and phosphorylated cdc25c (Ser216) were lower than those in the control group, and the differences were statistically significant (all P < 0.05). Conclusions:Targeted inhibition of PLK1 can inhibit the proliferation activity of cervical cancer cells in vitro, induce cell mitotic cycle arrest, and promote cell apoptosis; these may be achieved by regulating cell cycle and apoptosis-related proteins.

Objective To analyze the association of serum anti-glutamic acid decarboxylase antibody(GAD-Ab),C-peptide,and urinary albumin-to-creatinine ratio(UACR)with the changes in white matter and cognitive function in elderly patients with end-stage diabetic nephropathy(ESDN).Methods A total of 128 elderly patients with ESDN admitted to Nantong Sixth People's Hospital from November 2023 to November 2024 were enrolled.According to the Fazekas classification,they were assigned to white matter lesion group(grades 1-3)or non-white matter lesion group(grade 0).The levels of GAD-Ab,C-peptide,and UACR were compared between the two groups.The correlations between white matter lesions and the levels of GAD-Ab,C-peptide,and UACR in elderly ESDN patients were investigated.According to the Mini-Mental State Examination(MMSE)score,the patients were assigned to non-cognitive dysfunction group(with an MMSE score of 27-30)or the cognitive dysfunction group(with an MMSE score of<27).The basic data of the two groups were compared.The factors influencing cognitive function in elderly ESDN patients were analyzed,and ROC curve was used to evaluate the correlation between influencing factors and the occurrence of cognitive dysfunction in elderly ESDN patients.Results Among 128 elderly patients with ESDN,81 had white matter lesions,accounting for 63.28%.The levels of GAD-Ab,C-peptide and UACR in the white matter lesion group were all higher than those in the non-white matter lesion group(P<0.05).The Pearson correlation analysis showed that the white matter lesions in ESDN patients were positively correlated with the levels of GAD-Ab,C-peptide and UACR(P<0.05).There were 42 patients with cognitive dysfunction,accounting for 32.81%.There were significant differences in the 24 h urine protein quantitation(Upro),C-peptide,GAD-Ab,UACR,GFR,procalcitonin and hs-CRP levels between the cognitive dysfunction group and the non-cognitive dysfunction group(P<0.05).Binary Logistic regression analysis showed that 24 h Upro(OR=1.006,95%CI:1.003 to 1.008),GAD-Ab(OR=34.923,95%CI:5.779 to 211.058),C-peptide(OR=2.891,95%CI:1.669 to 5.010),UACR(OR=1.066,95%CI:1.032 to 1.102),procalcitonin(OR=1.221,95%CI:1.103 to 1.352),and hs-CRP(OR=1.471,95%CI:1.232 to 1.757)were risk factors for cognitive dysfunction in elderly ESDN patients,while rGFR level(OR=0.967,95%CI:0.950 to 0.984)was a protective factor for cognitive dysfunction in elderly ESDN patients(P<0.05).ROC curve analysis showed that the sensitivities of GAD-Ab,C-peptide,and UACR in evaluating cognitive dysfunction in elderly ESDN patients were 68.30%,73.20%,and 65.90%,respectively.The specificities were 63.20%,64.40%,and 72.40%,respectively.Their combination had a relatively high value in predicting cognitive dysfunction in elderly ESDN patients(AUC=0.892).Conclusion GAD-Ab,C-peptide,and UACR are associated with white matter lesions in elderly ESDN patients,and the combination of the three indexes has a relatively high value in predicting cognitive dysfunction in elderly ESDN patients.

Objective·To investigate the role of interleukin-1β(IL-1β)in predicting the severity of oral and maxillofacial space infection(OMSI),and to explore the key mechanisms regulating IL-1β release,the critical immune cell subpopulations involved,and the intercellular communication networks among immune cells in OMSI patients.Methods·A total of 62 OMSI patients admitted to the Department of Oral Surgery,Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine,from January to November 2023 were enrolled,including 20 patients with moderate infection,21 with severe infection,and 21 with extremely severe infection.Logistic regression analysis was performed to identify risk factors for extremely severe infection,and receiver operating characteristic(ROC)curves were constructed to evaluate the ability of the above indicators to predict extremely severe infection.Peripheral blood mononuclear cells(PBMCs)from 2 patients in each group(moderate,severe and extremely severe)and 2 healthy controls(GSE224198)were analyzed using single-cell RNA sequencing(scRNA-seq)to identify key pro-inflammatory cell subtypes and genes,and to examine their changing trends with increasing infection severity.Cell-cell communication was assessed using CellChat.Quantitative real-time polymerase chain reaction(qPCR)and Western blotting were used to validate inflammasome activation levels in PBMCs.Results·Compared with patients with moderate and severe infections,levels of procalcitonin(PCT)(P<0.05)and IL-1β(P<0.05)were significantly elevated in patients with extremely severe infection.Logistic regression identified IL-1β as an independent risk factor for extremely severe infection(OR=1.814,95%CI 1.256?2.621,P=0.002).The area under the ROC curve(AUC)for the combined prediction of extremely severe infection using IL-1β and PCT was 0.943.scRNA-seq revealed continuous upregulation of NLRP3(NOD-like receptor family pyrin domain-containing 3)and IL1B gene expression in monocytes as infection severity increased,with intermediate monocytes being the main IL1B-expressing cell subtype.IL-1Β-IL-1R signaling,C-C motif chemokine ligand(CCL)and intercellular adhesion molecule(ICAM)signaling were significantly enhanced in monocytes.Macrophage migration inhibitory factor(MIF)signaling between T cells and monocytes also increased notably.With infection progression,the mRNA levels of NLRP3 and IL1B in peripheral blood rose steadily,and the protein levels of NLRP3,caspase-1 p20,apoptosis-associated speck-like protein containing a CARD(ASC)and IL-1β were persistently elevated.Conclusion·The combined levels of IL-1β and PCT at admission can effectively predict extremely severe OMSI.NLRP3 inflammasome activation is observed in PBMCs of OMSI patients.The elevation of IL-1β is closely associated with intermediate monocytes.Monocyte-mediated IL-1Β-IL-1R,CCL and ICAM signaling pathways,along with T cell-mediated MIF signaling pathways,collectively promote the inflammatory response.

Since the outbreak of SARS in 2003,bat-borne viruses have become a hotspot in the field of emerging infectious diseases.So far,more than 200 vertebrate-infecting viruses have been discov-ered in bats,including coronaviruses,filoviruses,and hantaviruses,which pose a severe threat to public health.The discovery of these viruses not only enhances our understanding of virus diversity harbored by bats but also provides important data for controlling and preventing potential bat-re-lated emerging infectious diseases.Although significant progress has been made in understanding bat-borne virus diversity,many areas such as risk assessment and bat immunity remain largely un-explored.In this review,we summarize important bat-related viruses discovered in China,including coronaviruses,filoviruses,hantaviruses,and others,and discuss the urgent areas that need further research,providing a useful reference for understanding bat-borne viruses in China.

A 58-year-old female patient with anti-synthetase syndrome received compound sulfamethoxazole [containing trimethoprim (TMP) 80 mg and sulfamethoxazole (SMZ) 0.4 g, SMZ-TMP] 3 tablets thrice daily orally for the treatment of Pneumocystis jirovecii pneumonia. Before medication, the patient′s blood potassium was 3.3 mmol/L and blood chlorine was 116 mmol/L. Three days after SMZ-TMP treatment, the patient′s blood potassium was 5.7 mmol/L, blood chlorine was 114 mmol/L, blood pH was 7.3, urine pH was <5.5, blood chlorine was 114 mmol/L, and bicarbonate was 15 mmol/L. Hyperkalemia type renal tubular acidosis due to SMZ-TMP was considered. The dosage of SMZ-TMP was reduced to 2 tablets once daily orally. After 1 day of diuretic and potassium excretion treatments, the patient′s blood potassium levels returned to normal; after 2 days of the treatments, her blood chlorine was 109 mmol/L and bicarbonate was 17 mmol/L; after 3 days of the treatments, her chest CT showed emphysema in the neck and mediastinum. The dose of SMZ-TMP was changed to 3 tablets thrice daily orally, and at the same time intravenous infusion of ganciclovir 0.3 g twice daily was given. And again, her blood potassium increased and blood pH decreased. Sodium bicarbonate 1 g thrice daily orally was given to correct the acidosis. After adding SMZ-TMP for 2 days, SMZ-TMP dosage was reduced to 2 tablets once daily orally again. Seven days later, the patient′s vital signs were stable, her mediastinal emphysema was significantly improved, her blood potassium was 4.7 mmol/L, and blood pH was 7.4.

AIM:To explore the mechanism of doxorubicin/copper(DOX/Cu)complex induced copper death in hepatocellular carcinoma cells.METHODS:Human hepatocellular carcinoma cell line Huh7 was treated with DOX/Cu 0,2.5,4,7.5,10 and 12.5 μmol/L.The cell viability was detected by CCK-8 method.The cell proliferation level was observed by laser microscopy and proliferation kit.The cell invasion ability was determined by cell scratch assay.The flow cytometry was used to de-tect intracellular reactive oxygen species(ROS)and copper ion levels.And the western blot was used to detect intracellular iron-sulfur cluster proteins expression levels.RESULTS:With the increase of DOX/Cu concentration,cell viability,cell prolifera-tion and invasion ability decreased gradually.The copper ion chelating agent(TTM)can significantly restore the effects of DOX/Cu on cell viability.After DOX/Cu treatment,intracellular copper ion and ROS levels related to coproptosis were significantly increased,accompanied by the loss of iron-sulfur cluster proteins.CONCLUSION:DOX/Cu can inhibit hepatocellular carcinoma cells through cuproptosis.

Objective:Multivariate logistic regression analysis was performed to analyze the risk factors for intensive care unit-acquired weakness (ICU-AW) in critically ill patients.Methods:A total of 220 critically ill patients who were admitted to Intensive Care Unit, The First Hospital of Jiaxing from January 2020 to January 2022 were included in this study. The incidence of ICU-AW was recorded. Univariate analysis was conducted to investigate the factors related to ICU-AW, while multiple logistic regression analysis was performed to identify independent risk factors for ICU-AW in critically ill patients.Results:Among the 220 critically ill patients, 64 developed ICU-AW, resulting in an incidence of 29.1% (64/220). There were no significant differences in sex, age, history of alcoholism, history of smoking, marital status, hypertension, diabetes, or use of glucocorticoid (methylprednisolone sodium succinate for injection) between the ICU-AW group and the non-ICU-AW group (all P > 0.05). The proportion of patients with sepsis in the ICU-AW group was higher than that in the non-ICU-AW group [46.9% (30/64) vs. 15.4% (24/156)]. The proportion of patients who were immobilized in the ICU-AW group was higher than that in the non-ICU-AW group [89.1% (37/64) vs. 64.1% (100/156)]. The use of nerve blocker (vecuronium bromide for injection) was more prevalent in the ICU-AW group than that in the non-ICU-AW group [57.8% (37/64) vs. 23.1% (36/156)]. The Acute Physiology And Chronic Health Evaluation Ⅱ score in the ICU-AW group was higher than that in the non-ICU-AW group [16 (11, 23) vs. 12 (8, 17)]. The duration of mechanical ventilation in the ICU-AW group was longer than that in the non-ICU-AW group [8 (4, 13) days vs. 4 (3, 6) days]. The length of hospital stay in the ICU-AW group was longer than that in the non-ICU-AW group [10 (7, 17) days vs. 7 (5, 11) days]. The blood lactate level in the ICU-AW group was higher than that in the non-ICU-AW group [2 (1, 2) mmol/L vs. 1 (1, 2) mmol/L]. All differences were statistically significant ( χ2 = 24.30, 13.83, 24.70, Z = 3.83, 4.59, 3.97, 2.70, all P < 0.05). The results of the univariate analysis, when included in the multivariate logistic regression analysis, showed that sepsis, immobilization, duration of mechanical ventilation, blood lactate level, and Acute Physiology And Chronic Health Evaluation Ⅱ score were independent risk factors for ICU-AW (all P < 0.05). Conclusions:The incidence of ICU-AW is high and the risk factors for ICU-AW are complex. Therefore, targeted control of high-risk factors should be actively performed to prevent and treat ICU-AW.
