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 construct univariate and multivariate relapse free survival (RFS) prediction models for breast cancer patients with diabetes mellitus type 2 (T2DM) and to compare and select the model with higher predictive performance.Methods:A total of 912 breast cancer patients treated at the First Affiliated Hospital of Dalian Medical University from January 2010 to December 2016 were included, of which 202 patients had T2DM and 710 patients did not. Kaplan-Meier survival curve was drawn based on whether patients had T2DM, and log-rank test was performed based on whether patients had T2DM. All patients were randomly divided into a training set ( n=640) and a validation set ( n=272) at a ratio of 7∶3. Univariate and multivariate Cox proportional risk regression models were used to analyze RFS in breast cancer patients with the survival package. The "rms" package was employed to construct univariate and multivariate RFS prediction models for breast cancer patients with T2DM. Clinical decision curves and calibration curves were used to validate the models. The receiver operator characteristic (ROC) curve was used to compare and analyze the prediction performance of the two models. Results:There were no statistically significant differences between the training set and the validation set patients in terms of age, T2DM, surgical approach, axillary management methods, T stage, N stage, molecular sub-type, estrogen receptor (ER) 1, ER2, progesterone receptor (PR) , ER and PR consistency, Ki67, human epidermal growth factor receptor 2 (HER2) (all P>0.05) . There was a statistically significant difference in histological grade ( χ2=7.59, P=0.022) . Survival analysis showed that the 5-year RFS rate was 83.7% in patients with T2DM and 92.3% in patients without T2DM ( χ2=16.61, P<0.001) . Univariate analysis revealed that age ( HR=1.04, 95% CI: 1.03-1.06, P<0.001) , T2DM ( HR=2.31, 95% CI: 1.49-3.55, P<0.001) , surgical approach ( HR=2.39, 95% CI: 1.20-4.77, P=0.013) , axillary management methods ( HR=2.62, 95% CI: 1.72-3.98, P<0.001) , T stage (T 2: HR=2.13, 95% CI: 1.36-3.31, P<0.001; T 3: HR=6.90, 95% CI: 3.35-14.22, P<0.001) , N stage (N 2: HR=3.87, 95% CI: 2.12-7.07, P<0.001; N 3: HR=8.61, 95% CI: 4.71-15.75, P<0.001) , molecular sub-type (Luminal B: HR=2.74, 95% CI: 1.17-6.36, P=0.019; HER2 +: HR=3.64, 95% CI: 1.38-9.58, P=0.009; TNBC: HR=4.40, 95% CI: 1.71-11.34, P=0.002) , ER1 (>10%: HR=0.57, 95% CI: 0.37-0.90, P=0.016) , ER2 ( HR=0.57, 95% CI: 0.37-0.89, P=0.015) , and PR ( HR=0.56, 95% CI: 0.37-0.86, P=0.008) were all factors influencing RFS in breast cancer patients. Multivariate analysis demonstrated that age ( HR=1.04, 95% CI: 1.02-1.06, P<0.001) , T2DM ( HR=1.82, 95% CI: 1.16-2.85, P=0.009) , T stage (T 2: HR=1.60, 95% CI: 1.01-2.54, P=0.046; T 3: HR=2.64, 95% CI: 1.22-5.72, P=0.014) , N stage (N 2: HR=3.72, 95% CI: 2.01-6.88, P<0.001; N 3: HR=5.34, 95% CI: 2.78-10.25, P<0.001) , and ER1 (>10%: HR=0.63, 95% CI: 0.39-0.99, P=0.046) were independent factors influencing RFS in breast cancer patients. Based on the 10 and 5 variables with P<0.05 in the univariate and multivariate analyses respectively, the nomograms of the univariate and multivariate prediction models were constructed to evaluate the influence of factors such as T2DM on the postoperative RFS of breast cancer patients. Clinical decision curves and calibration curves indicated that both models had high predictive value for RFS in breast cancer patients, and the predictive results were highly consistent with the actual observed results. ROC curve analysis showed that there was no statistically significant difference in the area under the curve (AUC) of the two models for predicting the RFS rates of breast cancer patients in the training set and validation set at 36, 60, and 84 months (all P>0.05) , indicating that the predictive efficacy of the two models was comparable. The multivariate model is more suitable for clinical application because it uses fewer variables. Conclusions:Breast cancer patients with T2DM have poorer prognosis. Age, T2DM, T stage, N stage, and ER1 are independent factors influencing postoperative RFS in breast cancer patients. The multi-factor prediction model of RFS in breast cancer patients based on T2DM is more suitable for clinical application due to its higher predictive efficacy and fewer variables.

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.

Drug development encompasses multiple processes, wherein protein subcellular localization is essential. It promotes target identification, treatment development, and the design of drug delivery systems. In this research, a deep learning framework called LocPro is presented for predicting protein subcellular localization. Specifically, LocPro is unique in (a) combining protein representations from the pre-trained large language model (LLM) ESM2 and the expert-driven tool PROFEAT, (b) implementing a hybrid deep neural network architecture that integrates convolutional neural network (CNN), fully connected (FC) layer, and bidirectional long short-term memory (BiLSTM) blocks, and (c) developing a multi-label framework for predicting protein subcellular localization at multiple granularity levels. Additionally, a dataset was curated and divided using a homology-based strategy for training and validation. Comparative analyses show that LocPro outperforms existing methods in sequence-based multi-label protein subcellular localization prediction. The practical utility of this framework is further demonstrated through case studies on drug target subcellular localization. All in all, LocPro serves as a valuable complement to existing protein localization prediction tools. The web server is freely accessible at https://idrblab.org/LocPro/.

OBJECTIVE: To identify the optimal machine learning algorithm for predicting post-stroke epilepsy (PSE) within one year following acute stroke, establish a nomogram model based on this algorithm, and perform external validation to achieve accurate prediction of secondary epilepsy. METHODS: A total of 870 acute stroke patients admitted to the emergency department of Xiang'an Hospital of Xiamen University from June 2019 to June 2023 were enrolled for model development (model group). An external validation cohort of 435 acute stroke patients admitted to the Fifth Hospital of Xiamen during the same period was used to validate the machine learning algorithms and nomogram model. Patients were classified into control and epilepsy groups based on the development of PSE within one year. Clinical and laboratory data, including baseline characteristics, stroke location, vascular status, complications, hematologic parameters, and National Institutes of Health Stroke Scale (NIHSS) score, were collected for analysis. Nine machine learning algorithms such as logistic regression, CN2 rule induction, K-nearest neighbors, adaptive boosting, random forest, gradient boosting, support vector machine, naive Bayes, and neural network were applied to evaluate predictive performance. The area under the curve (AUC) of receiver operator characteristic curve (ROC curve) was used to identify the optimal algorithm. Logistic regression was used to screen risk factors for PSE, and the top 10 predictors were selected to construct the nomogram model. The predictive performance of the model was evaluated using the ROC curve in both the model and validation groups. RESULTS: Among the 870 patients in the model group, 29 developed PSE within one year. Among the nine algorithms tested, logistic regression demonstrated the best performance and generalizability, with an AUC of 0.923. Univariate logistic regression identified several risk factors for PSE, including platelet count, white blood cell count, red blood cell count, glycated hemoglobin (HbA1c), C-reactive protein (CRP), triglycerides, high-density lipoprotein (HDL), aspartate aminotransferase (AST), alanine aminotransferase (ALT), activated partial thromboplastin time (APTT), thrombin time, D-dimer, fibrinogen, creatine kinase (CK), creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH), serum sodium, lactic acid, anion gap, NIHSS score, brain herniation, periventricular stroke, and carotid artery plaque. Further multivariate logistic regression analysis showed that white blood cell count, HDL, fibrinogen, lactic acid and brain herniation were independent risk factors [odds ratio (OR) were 1.837, 198.039, 47.025, 11.559, 70.722, respectively, all P < 0.05]. In the external validation group, univariate logistic regression analysis showed that platelet count, white blood cell count, CRP, triacylglycerol, APTT, D-dimer, fibrinogen, CK, CK-MB, LDH, NIHSS score, and cerebral herniation were risk factors for PSE one year after acute stroke. Further multiple logistic regression analysis showed that APTT and cerebral herniation were independent predictors (OR were 0.587 and 116.193, respectively, both P < 0.05). The nomogram model, constructed using 10 key variables-brain herniation, periventricular stroke, carotid artery plaque, white blood cell count, triglycerides, thrombin time, D-dimer, serum sodium, lactic acid, and NIHSS score-achieved an AUC of 0.908 in the model group and 0.864 in the external validation group. CONCLUSIONS The logistic regression-based prediction model for epilepsy one year after acute stroke, developed using machine learning algorithms, showed optimal predictive performance. The nomogram model based on the logistic regression-derived predictors showed strong discriminative power and was successfully validated externally, suggesting favorable clinical applicability and generalizability.

Background and Aims:Acute inferior vena cava thrombosis(IVCT)commonly occurs secondary to inferior vena cava filter(VCF)implantation.If not promptly treated,it may lead to serious complications such as bilateral lower limb swelling and pulmonary embolism and can also reduce the likelihood of successful filter retrieval.Percutaneous mechanical thrombectomy(PMT)and catheter-directed thrombolysis(CDT)are currently the main interventional treatments for IVCT,but comparative studies evaluating their efficacy and safety remain limited.This study was to conduct a prospective randomized controlled trial to compare the clinical efficacy and safety of AngioJet mechanical thrombectomy versus conventional CDT in the treatment of acute IVCT and to explore factors influencing filter retrieval rates,thereby providing evidence-based guidance for clinical decision-making.Methods:From January 2022 to December 2024,patients diagnosed with acute IVCT following VCF implantation were prospectively enrolled at the Department of Vascular Surgery,Beijing Jishuitan Hospital,Capital Medical University.Patients were randomly assigned to either the CDT group(n=46)or the PMT group(n=48)according to the interventional procedure used.The two groups were compared in terms of filter retrieval rates,thrombus clearance outcomes,operative time,thrombolytic drug dosage,and incidence of complications.Logistic regression analysis was used to identify factors associated with primary filter retrieval.Results:A total of 94 patients were enrolled,with 46 in the CDT group and 48 in the PMT group.Compared to the CDT group,the PMT group demonstrated a significantly higher primary filter retrieval rate(77.1%vs.43.5%),grade Ⅲ thrombus clearance rate(70.8%vs.37.0%),and better postoperative thrombus scores.Additionally,the PMT group required lower urokinase doses and shorter thrombolysis duration(all P<0.05).The overall filter retrieval rate and 3-month IVC patency were similar between groups,both exceeding 93%.Regarding safety,the CDT group had a higher incidence of catheter-related infections and medical adhesive-related skin injury,while vagal reflex symptoms were more frequent in the PMT group.Logistic regression analysis identified thrombus clearance rate as an independent factor significantly associated with primary filter retrieval in the PMT group(OR=190.773,P<0.05).Conclusion:Compared to CDT,AngioJet mechanical thrombectomy combined with manual aspiration achieves higher thrombus clearance and primary filter retrieval rates in the treatment of acute IVCT while also reducing thrombolysis duration and drug dosage.However,attention should be paid to the increased risk of vagal reflex symptoms.There was no significant difference between the two groups in secondary filter retrieval rates or long-term IVC patency.The choice of intervention should be based on the patient's condition,timing of filter retrieval,and individualized clinical considerations.

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 investigate the ultrasonographic features and risk factors of patients with papillary thyroid carcinoma（PTC）located in the isthmus of the thyroid gland combined with lymph node metastasis（LNM）.Methods:A retrospective analysis was performed on a cohort of 614 patients diagnosed with isthmic PTC through postoperative pathological confirmation at Zhejiang Cancer Hospital between January 2020 and June 2024. The patients were divided into the LNM group（ n=225）and non-LNM（ n=389）based on the pathological results. The baseline information and ultrasound characteristics of the nodules were compared between the two groups. The risk factors associated with the development of LNM in patients with isthmus PTC were explored using univariate and multivariate Logistic regression analysis. The predictive performance was analyzed using ROC curve. Results:Comparison of the baseline information revealed that the age，maximum diameter of the cancerous lesion，gender were statistically different between LNM group and non-LNM group（all P<0.05）. Comparison of thyroid nodule ultrasound characteristics showed that there were statistically significant differences in boundary，aspect ratio，calcification，and color Doppler blood flow imaging（CDFI）grades between the two groups（all P<0.05）. Univariate and multifactorial Logistic regression analyses showed that the maximum diameter of the cancer foci（ OR=1.180，95% CI=1.119-1.244），gender is female（ OR=1.798，95% CI=1.187-2.723），and microcalcification（ OR=1.509，95% CI=0.183-12.441）were the factors affecting LNM of the isthmus PTC. The AUC value of the model used to predict the occurrence of LNM in isthmus PTC was 0.756（95% CI=0.717 - 0.795），with a sensitivity of 75.8% and a specificity of 63.6%. Conclusions:The maximum diameter of the cancer foci，microcalcification and gender female were independent risk factors for the occurrence of LNM in patients with thyraid isthmus PTC. The model constructed based on the above characteristics has a better predictive performance for thyroid isthmus PTC with LNM，and patients with the above high-risk character istics should be more vigilant.

Objective:To develop a scientific and practical questionnaire for general practice residents, and to conduct multidimensional and comprehensive evaluation of the quality of general practice teaching clinics.Methods:A preliminary draft of the questionnaire items was formulated based on a literature review and in-depth interviews. The Delphi method was employed to conduct two rounds of consultation with 14 experts. Following revisions, a convenience sampling method was used to invite general practice residents from three standardized residency training bases to test the reliability and validity of the questionnaire.Results:The questionnaire consisted of 23 items, covering the three dimensions of preparation, implementation process, and comprehensive evaluation of the teaching clinics. The response rates for the two rounds of the expert consultation were both 100.00%, with expert authority coefficients of 0.89 and 0.90, respectively. The overall Cronbach's α coefficient of the questionnaire was 0.93, and the correlation coefficients between each item score and the total score were all >0.30. Structural validity analysis revealed that three common factors were extracted from the questionnaire, with a cumulative variance contribution rate of 77.89%. Conclusions:The General Practice Teaching Clinic Quality Evaluation Questionnaire for Residents developed in this study demonstrates high reliability and validity. The questionnaire provides a scientific basis for the standardized assessment of teaching quality in general practice clinics. By incorporating resident feedback on the teaching process, the questionnaire promotes the development of a teaching clinic quality improvement mechanism focused on residents and plays a significant role in enhancing the teaching capabilities of supervising physicians in clinics.
