Objective To investigate the effects of Xuetong capsule on blood lipids and liver lesion in hyperlipidemic model animals. Methods Sixty ICR mice were randomly divided into six groups. The normal control group was fed with normal diet, the other groups were fed with high-fat diet to induce hyperlipidemia. After four weeks feeding, the three groups were given low, middle, and high doses of Xuetong capsules （0.5, 1.0, and 2.0 g/kg） by gavage, and the positive drug control group was given atorvastatin calcium （1.5 mg/kg） by gavage. The model group was given solvent （0.5% carboxymethyl cellulose sodium）. After treatment for 8 weeks, the body weight, organ index, blood lipids, blood glucose and liver function index were measured. The liver oil red staining was used to determine the lipid droplet content, and quantitative PCR was used to detect the expression of inflammatory factors TNF-α, IL-6, and IL-1β. Results The body weight, the weight of liver and spleen were significantly increased by high-fat diet. High-fat diet increased the organ indexes of the liver and spleen, the degree of liver oil red staining, and also significantly increased the levels of glucose, triglyceride （TG）, cholesterol （CHOL）, and low-density lipoprotein cholesterol （LDL-C） in serum. Compared with the model group, the level of TG has no significant change in low, middle and high doses groups. The level of CHOL in serum was reduced by Xuetong capsule with a dose dependent manner. There were significant difference between the model group and middle, high doses groups. The results of LDL-C were similar, the level of LDL-C was significantly reduced by middle and high doses groups [middle dose (0.55±0.21) mmol/L, high dose (0.52±0.22) mmol/L vs (0.81±0.29) mmol/L in model group, P<0.05]. Compared with the normal control, there was no significant difference in HDL-C levels between the high-fat model and each drug-treated group. Liver function showed that Xuetong capsules significantly reduced the degree of liver oil red staining and decreased the level of alanine aminotransferase （ALT） induced by high-fat diet. The body weight, the weight and organ indexes of liver and spleen were significantly reduced by positive drug control group. The levels of CHOL, LDL-C, and TG, and the degree of liver oil red staining were also significantly reduced in positive drug control group. Further studies have shown that high dose of Xuetong capsules significantly reduced the expression of TNF-α and IL-6 induced by high-fat diet （P<0.05）, while the reduction of IL-1β was not so significant （P>0.05）. Conclusion Xuetong capsules significantly reduced the body weight of animals with high fat, liver size, fat deposition, inflammatory damage and also significantly reduced blood lipid CHOL and LDL-C levels and transaminase elevation. The above effects may be related to Xuetong capsules reducing the expression of inflammatory factors such as TNF-α and IL-6 in the liver.

Objective:To explore the dual mediating effects of health belief and depression among health knowledge, social support, and health behaviors based on the capacity, opportunity, motivation-behavior (COM-B) model, and analyze the influencing factors of health behaviors in patients with ischemic stroke.Methods:This multi-center cluster sampling research recruited ischemic stroke patients ( n=1 696) who were hospitalized in neurology departments of five tertiary hospitals in Henan Province from October 2023 to October 2024. A cross-sectional investigation was conducted using the general information questionnaire, social support rating scale (SSRS), stroke prevention knowledge questionnaire(SPKQ), short form health belief model scale(SF-HBMS), health promoting lifestyle profile-Ⅱ (HPLP-Ⅱ), and patient health questionnaire-9(PHQ-9) to ultimately reveal the pathways and effect sizes among variables. Partial correlation analysis and multiple linear stepwise regression analysis were conducted to examine the relationships among social support, health knowledge, health belief, health behaviors, and depression in stroke patients by SPSS 26.0 software. Structural equation modeling was constructed using AMOS 28.0 software, and the mediating effect was tested using the Bootstrap method. Results:The scores of social support, health knowledge, health belief, and health behaviors among ischemic stroke patients were (37.46±9.94), (26.56±6.84), (75.62±12.62) and (130.79±26.27), respectively. The score of depression was 5.00 (2.00, 8.00). Health behaviors were positively correlated with health knowledge, social support, and health belief( r=0.333, 0.246, 0.267, all P<0.05), while negatively correlated with depression ( r=-0.146, P<0.05). Multiple linear stepwise regression analysis showed that health knowledge, social support, health belief, and depression were all influencing factors of health behaviors in ischemic stroke patients (all P<0.05). Health belief (effect value=0.068, 95% CI=0.048-0.093) and depression (effect value=0.009, 95% CI=0.003-0.018) both played partial mediating roles between health knowledge and health behaviors, accounting for 17.3%(0.077/0.446) of the total effect. Meanwhile, health belief (effect value=0.045, 95% CI=0.029-0.063) and depression (effect value=0.016, 95% CI=0.008-0.027) both played partial mediating roles between social support and health behaviors, accounting for 26.5%(0.061/0.230) of the total effect. Conclusion:Health knowledge and social support can not only directly influence health behaviors but also indirectly affect them through health belief and depression in patients with ischemic stroke.

Objective To optimize the extraction process of Xuetong capsules and establish its quality control method. Methods The extraction process was optimized by orthogonal experiment using ethanol reflux method to investigate the effects of different factors on diphenylstilbene, aloin and extraction yield. The content of 5 anthraquinone compounds in Xuetong capsule was determined by HPLC. Results The optimal extraction process was to add 10 times ethanol, with an ethanol concentration of 70%, and extract 3 times, each time for 1 h; 5 components had a good linear relationship with peak area within a certain concentration range, r>0.999 7; The range of sample recovery rate was 93.66%-96.85%, RSD range of 1.48%-1.66%. The content determination results of the 5 components in three batches of Xuetong capsules were （0.632-0.641）, （0.660-0.681）, （1.968-1.991）, （2.547-2.580）, and （1.076-1.101） mg/g. Conclusion The method was accurate, reproducible, and highly feasible, which could be references for producing and improving the quality control standards of Xuetong capsules.

Objective To analyze the influencing factors of malaria infection of labor service exported to overseas in Langfang City, in order to establish a visualization tool to assist clinicians in predicting the risk of malaria. Methods A total of 4 774 expatriate employees of the Nibei Pipeline Project of the Pipeline Bureau from October 2021 to August 2023 were taken as the subjects, and the gender, age, overseas residence area and Knowledge of malaria controlscores of the study subjects were investigated by questionnaire survey, and the possible risk factors of malaria were screened by logistic regression model. At the same time, the nomogram prediction model was established, and the subjects were divided into the training group and the validation group at a ratio of 2:1, and the area under the curve (ROC) and the decision curve were plotted to evaluate the prediction ability and practicability of the prediction model in this study. Results Among the 4 774 study subjects, 96 cases of malaria occurred, and the detection rate was 2.01%. Junior school （OR=1.723，95% CI:1.361-2.173）， and residence in rural areas（OR=2.091，95%CI:1.760 -3.100）were risk factors (OR>1), while protective measures（OR=0.826，95% CI : 0.781 - 0.901） and high malaria education scores （OR=0.872，95% CI : 0.621 - 0.899）were protective factors.The nomogram prediction model results showed that the area under the curve of the nomogram prediction model in the training group was 0.94 (95% CI : 0.85 - 1.00), while the validation group was 0.93 (95% CI : 0.80 - 1.00). The results of the decision curve showed that when the threshold probability of the population was 0-0.9, the nomogram model was used to predict the risk of malaria occurrence with the highest net income. Conclusion The nomogram prediction model (including gender, education, region, protection and malaria education score) established and validated in this study is of great value for clinicians to screen high-risk patients with malaria.
